Description

  The present invention uses a high place where a high place equipment used at a high place such as a surveillance camera or an illuminator can be moved up and down between a use position at a high place and a storage position at a low place by means of an extendable boom. The present invention relates to a lifter device with equipment.

  When monitoring the surroundings with a camera or performing night illumination outdoors, a surveillance camera or an illuminator is often installed at a high place. In addition, when the equipment is not used, the surrounding scenery is damaged or disturbed, so that the equipment is stored in a low place.

  Conventionally, for example, the telescopic illumination as shown in FIG. 22 is assumed to be able to raise and lower this type of equipment for use in high places (surveillance cameras and illuminators) between a use position at a high place and a storage position at a low place. The tower is widely used. The telescopic lighting tower corresponds to the lifter device with equipment for use in high places targeted by the present application.

  Also, known examples of this type of telescopic lighting tower include, for example, Japanese Utility Model Publication No. 63-46977 (Patent Document 1), Japanese Utility Model Publication No. 4-47848 (Patent Document 2), Japanese Utility Model Publication No. 5-4648 (Patent Document 1). There are some which are shown in literature 3).

  The telescopic illumination tower shown in FIG. 22 is configured such that a telescopic boom 102 is erected on a base 101 and an illuminator 132 is attached to an upper end portion of a distal end boom 123 of the telescopic boom 102. Four casters 111 are attached to the lower surface of the base 101. The telescopic boom 102 is a three-stage boom. In the telescopic illumination tower of FIG. 22, the upper end 132a of the illuminator 132 (the upper end of the illuminator mounting base) 132a is higher than the upper end 102a of the telescopic boom 102 by a height H1 (H1 = 20 to 30 cm, for example). (The same applies to Patent Document 2 and Patent Document 3.)

  The telescopic illumination tower shown in FIG. 22 retracts the telescopic boom 102 to the lowest position when not in use and positions the illuminator 132 at a low place, and extends the telescopic boom 102 to the maximum extent as shown by a chain line (reference numeral 102 ') when in use. Thus, the illuminator 132 can be used at a high place where a chain line is shown (reference numeral 132 ').

  By the way, in this type of telescopic lighting tower, it is required that the illuminator 132 can be lifted to a desired height (for example, a height of about 7 m from the ground) during use. In order to increase the height, it is conceivable to increase the length of each telescopic boom 102 per single boom or increase the number of single booms. However, if the length per single boom is increased, the height of the entire telescopic lighting tower (height H3 in FIG. 22) is increased even in the retracted state (the most contracted state of the telescopic boom), and the number of single booms is increased. (For example, a 4-5 stage boom) increases the weight and the configuration. For example, as shown in FIG. 22, when the telescopic boom 102 is a three-stage boom type, the illuminator 132 can be lifted up to a height (H2) of about 7 m in the fully extended state of the telescopic boom. Even if the telescopic boom 102 is in the most contracted state, the upper end height H3 of the illuminator 132 is about 3 m.

  Further, in order to carry the telescopic lighting tower of FIG. 22 to the place of use, the telescopic lighting tower is carried on a truck bed, and loading / unloading of the telescopic lighting tower onto the truck bed is performed using a crane or a forklift.

Japanese Utility Model Publication No. 63-46977 Japanese Utility Model Publication No. 4-47848 No. 5-4648

  Incidentally, the conventional telescopic illumination tower shown in FIG. 22 has the following various problems.

  (1) The illuminator 132 is attached to a fixed position of the tip boom 123 in an up-and-down state, and the upper end (upper end of the illuminator mounting base) 132a of the illuminator 132 is positioned higher than the upper end 102a of the telescopic boom 102. Therefore, the upper end 132a of the illuminator is at a considerably high position (height H3 = about 3 m) from the ground even when the telescopic boom 102 is in the most contracted state. Therefore, even when the telescopic boom 102 is in the most contracted state (stored state), the overall height H3 of the telescopic lighting tower is increased, and various disadvantages occur. In particular, when the telescopic lighting tower is transported by a truck, if the telescopic lighting tower is placed in an upright position on the truck bed, the overall height H3 of the telescopic lighting tower is set to the height of the truck bed (for example, 0.8 to 1 m). There is a risk that it will exceed the height limit (3.8m) by the Road Transport Vehicle Act.

  In the telescopic lighting tower of Patent Document 1 (Japanese Utility Model Publication No. 63-46977), the illuminator is suspended by an inverted L-shaped bracket so that the upper end of the illuminator is positioned below the upper end of the telescopic part of the telescopic boom. In this way, when the illuminator is positioned below the upper end of the telescopic boom, the illuminator does not protrude upward from the upper end of the telescopic boom. The height at becomes low. Therefore, in this case, in order to increase the head of the illuminator, it is necessary to increase the stroke of the telescopic boom, and as a result, the overall height of the telescopic lighting tower increases (or the number of boom stages of the telescopic boom increases).

  (2) When the equipment used in high places (illuminator or surveillance camera) is fixed to the tip of the telescopic boom, the lift of the equipment is limited to the stroke range of the telescopic boom. A telescopic boom with a long stroke must be used, thus increasing the overall height in the retracted state.

  (3) The telescopic lighting tower of the above-mentioned conventional example (FIG. 22) is a lighting device 132 with an umbrella (reflecting mirror) as an object to be lifted and lifted even if the lighting device is in a fixed posture in one direction. Although there is no hindrance, when the target equipment is, for example, an illuminating lamp without a cover that illuminates the entire circumference, or when the equipment is a plurality of surveillance cameras that monitor the entire area in the circumferential direction, the equipment is provided with a telescopic boom tip. If it is at a lower position, the distal end of the telescopic boom interferes with illumination and visibility.

  In the case where such a device for illuminating or monitoring the entire circumferential direction is installed at a position above the distal end of the telescopic boom, the telescopic boom distal end does not interfere with illumination or visibility, but is installed on the telescopic boom distal end. Min, the overall height will be higher.

  (4) In the telescopic lighting tower of FIG. 22, the four casters 111, 111,... On the lower surface of the base are grounded when in use, but the area range enclosed by each caster is relatively small, so In the state in which 102 is fully extended), the position of the center of gravity becomes high and becomes unstable. Further, if the installation ground of the base 101 is inclined, or if the ground at the caster position is concave or convex, the base cannot be installed horizontally (the telescopic boom 102 does not become a vertical posture), so it becomes more unstable. become.

  (5) A crane or forklift is required to load and unload the telescopic lighting tower on the truck bed. In particular, to load and unload the telescopic lighting tower on the truck bed at the site of use, the crane truck and forklift truck are also transferred to the site of use. There is a need to.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lifter device with equipment for use in high places (a monitoring camera and an illuminator) that can improve various problems of the conventional example.

  The present invention has the following configuration as means for solving the above problems. The present invention is directed to a lifter device with equipment for use in high places used at high places such as surveillance cameras and illuminators.

[Invention of Claim 1 of the Present Application]
The lifter device with equipment for use in high places of the invention of claim 1 of the present application stores equipment for use in high places such as surveillance cameras and illuminators in a low place by a telescopic boom erected on the base. It can be moved up and down between a position and a use position at a high place.

  In the case of supporting the lifter device with equipment for use in high places only by a base, a base having an appropriate area is used in order to ensure stability during use. In addition, casters may be attached to the lower surface of the base near the four corners.

  For example, a two-stage telescopic boom (three-stage boom) can be used as the telescopic boom used in the lifter device with equipment for use in high places of the present application. Further, only one telescopic boom may be used, but two telescopic booms may be used at intervals on the base. In addition, when using two expansion-contraction booms, it is good to install a high place use equipment between both expansion-contraction booms.

  The equipment for use in high places (monitoring camera and illuminator) is installed so as to be vertically displaced between a downward movement position below the upper end of the telescopic boom and an upward movement position above the upper end of the telescopic boom. This equipment for use in high places is preferably guided by a vertically extending guide rod so that it can be displaced vertically with respect to the tip boom of the telescopic boom. In addition, it is good to attach the equipment used for high places to an appropriate mounting base, and to be able to displace the equipment used for high places up and down via the mounting base.

  In the lifter device with equipment for use in high places according to claim 1 of the present application, vertical movement means for moving the equipment used in high places up and down between the lower movement position and the upper movement position, and equipment for use in high places in the lower movement position. And a supporting means for supporting at each of the upward movement positions.

  As the vertical movement means, an appropriate lifting device such as a telescopic cylinder or a chain lift can be used.

  As each support means, any appropriate means can be used as long as it can support the equipment for use in high places at the lower movement position and the upper movement position. For example, a stopper (which may be a lock pin) that restricts the downward movement of the equipment for use in high places can be used as the support means for the downward movement position, and a lock pin can be used as the support means for the upward movement position.

  And the lifter apparatus with a high place use equipment of this Claim 1 is used as follows.

  First, when the equipment used at a high place is not used, the telescopic boom is contracted to the minimum, and the equipment used at a high place is supported by a supporting means (for example, a stopper) at a downward movement position below the upper end of the telescopic boom. In this state (low storage state), since the telescopic boom is contracted to the minimum and the equipment for use in high places is positioned below the upper end of the telescopic boom, the height of the entire lifter device is low.

  On the other hand, when using the high-altitude equipment, the telescopic boom is extended to the maximum while the high-altitude equipment is supported by the support means (for example, a lock pin) at the upward movement position above the upper end of the telescopic boom. In this state (high-use usage state), the telescopic boom is fully extended and the high-altitude equipment is located above the upper end of the telescopic boom, so the height of the high-altitude equipment is high. Further, in this high altitude use state, the high altitude equipment is positioned above the upper end of the telescopic boom, so that there is no obstruction (upper end of the telescopic boom) around the high altitude equipment.

Further, in the invention of claim 1, in the above Symbol altitude using equipment with lifter devices, sharing the vertically moving means in telescopic boom.

Furthermore, in the invention of claim 1, the extension of the telescopic boom has a temporary holding means for provisionally holding the altitude used equipment at a position moved upward and altitude using equipment with telescopic boom top to upward position and the After temporarily holding the equipment used at a high place with the temporary holding means, the telescopic boom is shrunk so that the equipment used at a high position is positioned in the upward movement position with respect to the upper end of the telescopic boom. The upper moving position support means can be connected to the upper end of the telescopic boom.

That is, according to the first aspect of the present invention, the equipment used at high places is connected to the upper end of the telescopic boom (the equipment used at high places moves up and down together with the upper end of the telescopic boom) and temporarily held by the temporary holding means (high It can be supported (replaced) in two forms, that is, the place-use equipment is in a free state relative to the upper end of the telescopic boom.

Therefore, in the lifter device with equipment for use in high places according to the first aspect of the present invention, the equipment for use in high places can be changed to the downward movement position and the upward movement position with respect to the upper end of the telescopic boom. A telescopic boom can be used as the moving means.

[Invention of claim 2 of the present application]
The invention of claim 2 of the present application is such that the four corners of the base are supported by the jacks so as to be movable up and down in the lifter device with equipment for use in high places of claim 1 . Each jack can be synchronously expanded and contracted, and the expansion / contraction amount can be individually adjusted.

  In the lifter device with equipment for use in high places according to the second aspect of the present invention, even when the installation ground is inclined or uneven, the amount of expansion / contraction of each jack is adjusted individually to make the base stand in a horizontal position. Can be used in a maintained state.

  Moreover, in the lifter device with a high place use equipment of this invention of Claim 2, the part for the expansion / contraction stroke of a jack can be added separately from the expansion / contraction stroke of a telescopic boom as a lift of the high place use equipment.

  By the way, this lifter device with equipment for use in high places is mounted on a truck bed and transported on public roads, but when traveling on public roads, there are height restrictions due to the road transport vehicle method, and use in high places in the retracted state It is necessary to keep the overall height of the lifter device with equipment itself low. That is, the total height of the lifter device with equipment for use in high places is the height obtained by subtracting the height of the truck bed (for example, 0.8 to 1 m) from the height limit (3.8 m) by the road transport vehicle method (for example, 2.8). ~ 3m). As described above, in order to keep the height of the lifter device with equipment for use in high places low, it is necessary to use a boom with a short single boom length as an extendable boom, and extend and retract with a boom having a small number of boom stages (eg, a three-stage boom). The stroke may be shortened and a sufficient lift may not be secured. If a multistage boom (for example, a 4-5 boom) is used as the telescopic boom, the telescopic stroke of the telescopic boom becomes longer, but there is a disadvantage that the structure becomes complicated and the weight becomes heavy.

  Therefore, in the lifter device with equipment for use in high places according to the second aspect of the present invention, since the jack for raising and lowering the base is provided separately from the main telescopic boom, the truck transport in which the overall height of the lifter device itself is limited. Even if it is a type | mold, the expansion-contraction stroke of an expansion-contraction boom can be reduced by the expansion-contraction stroke of a jack (single boom length can be shortened).

[Invention of claim 3 of the present application]
The invention of claim 3 of the present application is the lifter device with equipment for use in high places according to claim 2, wherein a pair of front and rear outriggers in which the inner cylinder protrudes and retracts on the left and right sides with respect to the outer cylinder are attached to the front and rear positions of the base. In addition, jacks (four in total) are respectively attached to the distal ends of the outrigger inner cylinders.

  Each jack uses one having a longer expansion / contraction stroke than the height of the truck bed for transporting the lifter device. The height of the truck bed that transports the lifter device of the present application is, for example, about 0.8 to 1 m, but an extension stroke (for example, 1) that allows the lower surface of the base of the lifter device to float as a jack from the upper surface of the truck bed. Those having an extension stroke of about 0.6 m are used.

Further, in the lifter device with equipment for use in high places according to claim 3 , in the retracted state of each outrigger, the distance between the left and right outer surfaces of the entire lifter device is within the width of the truck bed, while in the fully extended state of each outrigger. The distance between the inner surfaces of the left and right jacks is set so as to extend to a position straddling the truck bed in the width direction. The lifter device with equipment for use in high places used in claim 3 has a left and right width (interval between left and right outer surfaces) of about 1.8 m in the outrigger retracted state, and the carrier is used as a truck for transporting the lifter device. A wider one is used.

The lifter device with equipment for use in high places according to claim 3 can be loaded and unloaded on the truck bed by itself as follows.

  In other words, in order to load this lifter device with equipment for use in high places on a truck bed, each outrigger extends to the left and right outwards from the state where the lifter device is installed on the ground (base is grounded) → each jack is extended. The base is raised above the height of the truck bed → The truck bed is moved backward into the space below the base → Each jack is reduced and the base is seated on the truck bed → Each outrigger is set to the minimum position of the jack. Loading is completed by storing. Further, in order to lower the lifter device with equipment for use at high places on the truck bed, the above-described operation at the time of loading may be performed in the reverse order.

[Effect of the invention of claim 1 of the present application]
The lifter device with equipment for use in high places according to claim 1 of the present invention is configured such that the equipment for use in high places (monitoring camera and illuminator) is moved downward between the upper end of the telescopic boom and the upper movement position above the upper end of the telescopic boom. It is installed so that it can be displaced up and down, and is configured to be able to support the equipment for use in high places in the downward movement position and the upward movement position by the vertical movement means and the respective support means.

  Therefore, the lifter device with equipment for use in high places according to the first aspect of the present invention has the following effects.

  (1) When storing the equipment used in high places in a low place when not in use, the height of the entire lifter device can be lowered by supporting the equipment used in high places in the downward movement position (below the upper end of the telescopic boom) Compactness can be achieved. In addition, if the height of the entire lifter device at the time of storage is kept low as described above, the height limit when the lifter device is loaded on a truck bed and travels on a public road can be afforded.

  (2) When lifting the equipment used at high altitudes during use, support the equipment used at high altitudes in the upward movement position (above the upper end of the telescopic boom), so that the equipment used at high altitudes is as much as the telescopic stroke of the telescopic boom. Apart from that, it is possible to take an extra head by the amount of vertical displacement of the equipment used at a high position with respect to the upper end of the telescopic boom.

  (3) When the high-altitude equipment is in the upward movement position with respect to the tip of the telescopic boom, there is no obstacle (upper end of the telescopic boom) around the high-altitude equipment when the high-altitude equipment is used at high locations. Even if the high place use equipment is located below the upper end of the telescopic boom in the retracted state, the upper end of the telescopic boom does not obstruct the visibility of the high place use equipment.

Further, the invention of claim 1, in altitude using equipment with lifter devices over reporting, by sharing the vertical movement means with telescopic boom, the altitude using equipment of the downward position and the upward position It is possible to use a telescopic boom to move up and down.

Therefore, in addition to the above-described effect, the lifter device with equipment for use in high places according to the first aspect of the present invention eliminates the need for dedicated up-and-down moving means, thereby reducing costs and achieving weight reduction.

[Effect of the invention of claim 2 of the present application]
The invention of claim 2 of the present application is such that the four corners of the base are supported by the jacks so as to be movable up and down in the lifter device with equipment for use in high places of claim 1 .

Therefore, the lifter device with equipment for use in high places of the invention of claim 2 has the following effect in addition to the effect of claim 1.

  First, as a lift for equipment used at high altitudes, a lifter device with equipment used at high altitudes can be added to the extension stroke of the jack separately from the extension stroke of the extension boom, and the overall height is kept low in the retracted state. However, it is possible to increase the height of equipment used at high altitudes. Alternatively, the expansion / contraction boom of the telescopic boom can be reduced by an amount corresponding to the increase in the lift by the jack (the length of the single boom can be shortened), and as a result, the overall height of the lifter device in the retracted state can be further reduced.

  In addition, when using equipment used in high places, by adjusting the expansion and contraction amount of each jack individually, the base can be maintained in a horizontal posture even when the installation ground is inclined or uneven, Use posture is stable.

[Effect of the invention of claim 3 of the present application]
According to the third aspect of the present invention, in the lifter device with equipment for use in high places according to the second aspect , the expansion / contraction stroke of each jack is made longer than the height of the truck bed, and each jack protrudes left and right beyond the truck bed width by an outrigger. I am trying to let you.

Thus, at heights using equipment with lifter device of the invention as claimed in claim 3, in addition to the above effects of Claim 2, there is an effect that it unloading the altitude using equipment with lifter devices truck bed on their own.

The auxiliary bracket 55 located at the position facing the pin unit mounting bracket 54 is formed with a pin hole 55b into which the pin tip portion 74a of the pin unit 72 of the temporary holding means 70 is inserted.

  Then, each pin unit 72 of the temporary holding means 70 is in a non-engagement state with respect to the pin receiving base 71 when the pin 74 is retracted as shown by a solid line in FIG. When the pin 74 is protruded at the raised position (FIGS. 8 to 10), the pin tip 74a engages with the upper surface (recessed portion) of the pin receiving base 71 as shown by a chain line (74a ') in FIG. (To be listed).

  A pair of outriggers 4, 4,... Are installed at each of the front and rear ends of the base 1 in a left-right direction (a total of four). Each of the outriggers 4, 4... Is one in which the inner cylinder 42 protrudes and protrudes on the left and right sides with respect to the outer cylinder 41. The appearance stroke of each inner cylinder 42 is about 60 to 70 cm on one side.

  Jacks 43, 43,... Are respectively attached to the distal ends of the inner cylinders 42, 42,. Each jack 43, 43,... Has an expansion / contraction stroke of about 1.6 m.

  In the state where the outriggers 4, 4,... Are fully extended as shown by the chain lines in FIG. 7, the jacks 43, 43,... Have a longitudinal interval (FIG. 6) of about 2.2 to 2.3 m, The left-right distance (FIG. 7) is about 3.1 to 3.2 m, and this lifter device can be supported at four points in a wide area range. Further, when each jack 43, 43,... Is extended as shown in FIGS. 6 and 7, the lower surface of the base 1 can be separated from the ground by about 1.5 m, and casters 11 are attached to the lower surface of the base. Even in this state, the lower surface of the caster 11 can be lifted from the ground by about 1.15 to 1.2 m.

  By the way, the lifter device with equipment for use in high places according to the first embodiment can be loaded and unloaded on the truck bed 81 by itself as shown in FIGS. The truck bed 81 has a height of about 0.8 to 1 m and a lateral width of about 2.0 to 2.2 m.

  When all the outriggers 4, 4,... Are contracted to the minimum, the distance between the left and right outer surfaces of the entire lifter device (for example, 1.8 m) is smaller than the width of the truck bed 81, as shown by the solid line in FIG. . Therefore, in a state where the lifter device with equipment for use in high places is mounted in the center of the truck bed 81, the left and right outer surfaces of the lifter device do not protrude from the left and right width of the truck bed 81. On the other hand, when all the outriggers 4, 4,... Are fully extended, the inner surface spacing (for example, about 2.8 m) of the jacks 43, 43,. It becomes considerably larger than the width of the loading platform 81. Therefore, when all the outriggers 4, 4,... Are fully extended, the jacks 43, 43,... Can be extended and contracted even when the lifter device is placed on the truck bed 81.

  The extension stroke of each jack 43, 43,... Is 1.6 m. When each jack 43 is extended to the maximum, the lower surface of the base 1 can be lifted about 1.5 m from the ground as shown in FIG. . Therefore, a space higher than the height (0.8 to 1 m) of the truck bed 81 can be secured below the lower surface of the base 1. In this case, as shown in FIG. 9, even when the caster 11 is attached to the lower surface of the base 1, the truck bed 81 can be sent into the lower space. If the caster 11 on the lower surface of the base 1 is removed when transported on 81, the total height of the lifter device with equipment for use in high places becomes low, and the height restriction by the road transport vehicle method (3.8m) ) Can afford.

  In the lifter device with equipment for use in high places of this embodiment, an enclosure 12 that surrounds the outer portion on the base 1 is provided. This enclosure 12 has each side part which coat | covers the circumference | surroundings 4 surface on the base 1, and the top | upper surface part which can coat | cover the upper part use equipment 3 and the telescopic booms 2 and 2 in a retracted state.

The control panel 15 is installed on the side where the side doors 13 and 13 are located, and the control panel 15 is operated by opening the side doors 13 and 13. In addition, when the telescopic booms 2 and 2 are extended or the altitude equipment 3 is moved up, the top doors 14 and 14 are opened.

  The lifter device with equipment for use in high places according to the first embodiment is used as follows.

  First, in the first usage example, as shown in FIGS. 1 to 3, the caster 11 is used, but in this case, the lifter device can be manually moved and adjusted in the use position. In this initial state, each telescopic boom 2, 2 is contracted to the minimum, and each downward movement position support means (stopper) is at a position where the elevating body (each slide cylinder 52) is lowered to the lowest movement position with respect to each guide bar 51. ) 60 is supported. At this time, the pin 64 of each pin unit 62 of the upward moving position support means 61 is in the immersive position (lock release position), and the pin 74 of each pin unit 72 of the temporary holding means 70 is also in the immersive position (non-removed position). In the engaged position).

  When the use position and orientation of the lifter device are determined, the outriggers 4, 4,... Are extended as shown by the chain lines in FIG. 7, and then the jacks 43, 43,. It is supported by the jacks 43, 43 of the book. At this time, when the use position is an inclined ground or the ground contact portion of each jack 43 is uneven, the expansion / contraction amount of each jack 43, 43,... Is adjusted to hold the base 1 in a horizontal posture.

  Next, when each of the telescopic booms 2 and 2 is extended by the first stage (in the illustrated example, the intermediate boom 22 is extended), as shown in FIGS. 8 and 9, the telescopic booms 2 and 2 are moved up and down together with the four guide rods 51, 51. The body (the equipment used at a high place 3, the mounting base 33, the support base 35, and each slide cylinder 52) moves upward, and the pin 74 of the pin unit 72 of the temporary holding means 70 is the upper surface of the pin receiving base 71 on the proximal boom 21 side. The extension operation of the telescopic booms 2 and 2 is stopped at a position where the telescopic booms 2 and 2 are moved up to a height where they can be engaged with each other. 10, the pins 74 of the pin units 72 (there are four) of the temporary holding means 70 are protruded to the lock position, and the pin tips 74a are placed on the pin holders 71. Engage with. In order to engage the pin tip portion 74a on the pin receiving base 71, the extension of the telescopic boom 2 is temporarily stopped at a position where the pin 74 of the pin unit 72 is moved to a position slightly higher than the upper surface of the pin receiving base 71. Then, after projecting the pin 74 to the lock position, the telescopic boom 2 is contracted so that the tip 74a of the pin 74 is locked (mounted) on the pin receiving base 71. The pin holder 71 can be easily and reliably engaged. In the temporary holding state by the temporary holding means 70 (the four pin tip portions 74a are engaged on the four pin receiving bases 71), the lifting body (the equipment for use in high places 3, the mounting base mounting base, the support) The load of the base support base and each slide cylinder 52) is supported by four pin bases 71. In this state (the state shown in FIGS. 8 and 9), the elevating body is still in the downward movement position A with respect to the upper end of the telescopic boom, and the upper part of the telescopic boom 2, the overhanging material 24, each guide bar 51, etc. are high. They are at the same height as the high-use equipment 3 and are in a position where they obstruct the field of view of the high-use equipment (monitoring camera) 3.

  Next, when each telescopic boom 2 is contracted to the minimum while the lifting body is temporarily held by the temporary holding means 70, the four guide rods 51 move downward relative to the respective slide cylinders 52 as shown in FIG. Then, the elevating body (the equipment for use in high places 3) is located at the upward movement position B with respect to the upper end of the telescopic boom (the obstruction is removed from the side peripheral portion of the surveillance camera). In the state of FIG. 11, as shown in FIG. 12, the pin tip portion 64 a of the pin unit 62 of the upward moving position support means 61 faces the pin insertion hole 68 located near the upper portion of the guide bar 51 (4 In other words, by projecting the pin 64 of the pin unit 62 to the lock position, the pin tip end portion 64a is engaged with the pin insertion hole 68 (all four locations). In this state, each guide bar 51 and each slide cylinder 52 are integrally coupled.

  In this embodiment, in the temporary holding state by the temporary holding means 70, the pins 74 (pin tip portions 74a) are merely placed on the upper surfaces of the pin receiving bases 71 (shown in chain lines in FIG. 10). The telescopic boom 2 can be extended (moving up and down) even in the holding state. However, in the case of using a type in which the pin is inserted into the pin hole as the temporary holding means, After the upper moving position support means 61 (the pin 64 and the pin insertion hole 68) is locked, the pin of the temporary holding means is unlocked with respect to the pin hole.

  Next, when each telescopic boom 2 is extended from the state shown in FIG. 11 (upward moving position support means 61 is locked), each guide bar 51 is moved up together with the telescopic boom tip (projecting member 24). As a result, the elevating body (the equipment used at a high place 3 to each slide cylinder 52) also moves up. In the state in which each of the telescopic booms 2 and 2 is extended to the maximum, as shown in FIG. 13, the equipment for use in high places 3 can be lifted to a height of H4 (H4 = 6 to 7 m). In addition, when there is anxiety about stability in the high place use state shown in FIG. 13, you may stretch the recording wire 9 in four directions. In this case, the upper end of the holding wire 9 is connected to the bracket portion of the overhanging material 24 in the contracted state of the telescopic boom, and the holding wire 9 is lifted after the height-use equipment 3 is lifted to the use height shown in FIG. It is preferable to connect the lower end of the anchor to the anchor.

  In the lifter device with equipment for use in high places according to the first embodiment, since it can be supported by the four jacks 43 in the use state, the stability is improved, and the base 1 can be used in a state where it is accurately maintained in a horizontal posture. Further, in the retracted state, the telescopic booms 2 and 2 can be reduced to the minimum, and the device for use in high places 3 can be lowered to the downward movement position A below the upper end of the telescopic boom, so that the total height in the retracted position is kept low. be able to. Furthermore, in the usage state of the high place use equipment 3, the extension amount of the jack 43, the increase amount from the lower movement position A to the upper movement position B, and the extension amount of the telescopic boom 2 can be increased by the total stroke. Therefore, even if the overall height can be kept low in the stored state, the required head can be secured.

  Moreover, in the lifter device with equipment for use in high places of the first embodiment, even if the four casters 11 are attached to the lower surface of the base 1 as in the first use example, the lifter device can be operated by itself. Can be loaded and unloaded on a truck bed. That is, as shown by the chain line in FIG. 7, in the state where the outriggers 4 are extended and the jacks 43 are extended to the maximum, a space is secured between the lower surface of the caster 11 and the ground so that the truck bed can be taken in and out. It is like that. Therefore, when the lifter device is lowered from the truck bed to the ground, and when the lifter device is placed on the truck bed from the ground, the outriggers 4 and the jacks 43 are operated in a predetermined order. It can be loaded and unloaded on its own without using a crane.
