Description

  The present invention relates to a container that can be mounted on a vehicle body and can store a conveyed product inside.

    2. Description of the Related Art Conventionally, containers that can store a liquid such as water or petroleum, a powdered fluid such as food or chemicals, or a solid such as earth and sand or garbage are known. Since the container can be mounted on a vehicle body of a transport vehicle having a loading device, the container can be easily moved to a predetermined site. (For example, see Patent Document 1)

  An example of the container is a tank container used for water supply work at a disaster site or the like. The tank container has a tank capable of storing potable water therein. When using the tank container, first, a manhole covering an opening provided on the upper surface of the tank of the tank container stored in a storage or the like is opened. Thereafter, drinking water is poured into the tank from the opening, and the drinking water is stored in the tank. And the tank container which stored drinking water is mounted on a conveyance vehicle, and a tank container is moved to the predetermined site (for example, water supply site which performs water supply operation | work). After arriving at the water supply site, the transport vehicle lowers the tank container on the vehicle body to the ground in order to transport another tank container to another site. The grounded tank container discharges drinking water from the outlet and performs water supply work.

Japanese Patent No. 3738868

However, the discharge port of the tank container is located near the bottom of the tank so that the potable water in the tank can be supplied with as little residual amount as possible, so if the tank is low in the height direction when the tank container is grounded The position of the discharge port may be close to the ground, making water supply work difficult.
Therefore, in order to increase the position of the discharge port when the tank container is grounded, it is conceivable that the lower part of the tank container is grounded via a support member, and the tank position of the tank container is increased by the height of the support member. . However, when the position of the tank is increased by the support member, the height of the manhole on the upper surface of the tank from the ground is further increased, so that it takes time to supply water into the tank.
Accordingly, the present invention has been made in view of the above-described problems, and an object thereof is to provide a container that facilitates the operation of loading into the container and the operation of discharging out of the container.

    In order to achieve the above object, a container according to the present invention comprises a container main body capable of storing a conveyed product therein and a holding device capable of supporting the container main body, and the holding device lowers the container main body when grounded. It is characterized in that it can be supported at a high position in the container height direction compared to the position and the low position.

Further, the holding device has a leg portion, and the leg portion includes a base-side leg portion whose one end is attached to the container body, and a base-side leg portion on the other end side of the base-side leg portion. It consists of a front leg that is swingable between a projecting position that projects downward and a retracted position that swings relative to the base leg, and a base grounding member is provided at the lower end of the base leg. The first leg contact member that contacts the ground when the front leg is in the protruding position and the first leg that contacts the ground when the front leg is in the retracted position are provided on the front leg. A two-tip grounding member is provided.

According to this configuration, the container main body can be supported at a low position and a high high position in the container height direction as compared with the low position. It is possible to work easily by setting it to the low position, and when the worker works at the lower part of the container, the work can be easily done by setting the container body to the high position. Efficiency can be improved.

In addition , as a grounding part to be grounded when the front leg is refracted , a base grounding member is provided on the base leg and a second grounding member is provided on the front leg. Even if the storage location is muddy due to rain, if the front leg is refracted and grounded, the installation area of the grounding portion is large, so that the holding device is buried in the ground and the container can be prevented from tilting.

    According to the present invention, since the container body can be supported at a low position and a high position higher in the container height direction than the low position, the height of the container main body can be changed according to work, Work efficiency can be improved.

Since each discharge port 13d has a faucet 13e, when the faucet 13e is twisted with the central opening / closing valve 13c opened, the drinking water in the tank is discharged from the discharge port 13d and can be supplied.

  The holding device H of the present invention is provided with a pair of left and right front legs HF provided on the front side of the container body 1 and a pair of left and right sides on the rear side of the container body 1 as shown in FIGS. And rear leg HR. Since the left and right front leg portions HF and the left and right rear leg portions HR have the same configuration, the right front leg portion HF and the rear leg portion HR will be described below.

    As shown in FIGS. 1 and 4, the front leg HF is configured to be foldable by a base leg 14 and a tip leg 15 attached to the base leg 14. More specifically, as shown in FIGS. 5 and 6, the upper end of the base side leg portion 14 is fixed to the lower surface of the right end portion of the connection frame 4 by welding. The base side leg portion 14 is formed of a channel material whose rear surface and lower surface are opened. A stopper 16 described later is provided on the rear surface of the base side leg portion 14. A hole 17 is formed in the lower outer side surface of the base side leg portion 14. A pin 18 can be inserted into the hole 17 so that the pin 18 is urged in a direction to be inserted into the hole 17 by a spring (not shown). A base grounding member 19 is provided at the lower end of the base leg 14.

    A front-side leg 15 is provided at the center of the base-side leg 14 via a pin 20 so as to be swingable with respect to the base-side leg 14. The front-side leg 15 is a square member that is hollow and has a rectangular cross section, and has a dimension that can be disposed in the base-side leg 14. Accordingly, the front leg HF has a protruding position where the front leg 15 shown in FIG. 5 protrudes below the base leg 14 and the front leg 15 shown in FIG. It is possible to switch to the storage position swinging backward. The outer side surface of the front leg 15 is provided with a hole 21 through which the pin 18 can be inserted when the front leg 15 protrudes below the base leg 14. Accordingly, as shown in FIG. 5, by inserting the rear pin 18 with the front side leg portion 15 projecting below the base side leg portion 14 into the holes 17 and 21, the front side leg portion 15 is moved to the base side. It is fixed to the leg part 14 and the front leg part HF is held at the protruding position. When the front leg HF is in the retracted position, as shown in FIG. 6, the stopper 16 and the rear surface of the front leg 15 and the pin 18 and the front surface of the front leg 15 abut each other. Thus, it is possible to keep the front side leg portion 15 swinging backward, and the front side leg portion HF is held in the retracted position. A first front portion grounding member 22 that comes into contact with the ground when the front side leg portion HF is in the protruding position is provided on the lower surface of the front portion side leg portion 15. A front surface of the front leg 15 is provided with a second front ground member 23 that can come into contact with the ground when the front leg HF is in the retracted position.

As shown in FIGS. 1 and 4, the rear leg portion HR is provided at both left and right end portions of the rear frame 24 provided at the rear end portions of the stringers 3 and 3, and slides with a cylindrical member 25 described later. The member 27 can be extended and contracted.
The rear leg portion HR will be described in detail. As shown in FIGS. 7 and 8, a cylindrical member 25 having a rectangular cross section is fixed to the rear frame 24 by welding. The cylindrical member 25 has an open upper surface and a lower surface. In addition, a hole 26 is provided at the center of the side surface of the cylindrical member 25. A sliding member 27 having a rectangular cross section is inserted into the cylindrical member 25 so as to be slidable in the vertical direction with respect to the cylindrical member 25. A lid member 28 wider than the cross section of the cylindrical member is welded and fixed to the upper surface of the sliding member 27, and a handle 29 is attached to the upper surface of the lid member 28. A bracket 30 is fixed to the lower end of the sliding member 27, and a roller 31 is rotatably attached to the bracket 30.

    An upper hole 32 (see FIG. 8) and a lower hole 33 (see FIG. 7) that coincide with the hole 26 of the tubular member 25 when the sliding member 27 is slid are provided on the side surface of the sliding member 27. It has been. The position of the upper hole 32 is formed so as to coincide with the hole 26 when the lower surface of the lid member 28 contacts the upper surface of the tubular member 25 (see FIG. 7). When the pin 34 is inserted in a state where the upper hole 32 and the hole 26 are aligned, as shown in FIG. 7, the rear leg HR becomes an extended position where the roller 31 and the lower surface of the cylindrical member 25 are separated from each other. When the pin 34 is inserted in a state where the lower hole 33 and the hole 26 are aligned, as shown in FIG. 8, the rear leg HR has a contracted position where the roller 31 and the lower surface of the cylindrical member 25 are close to each other. Become. Accordingly, the rear leg HR is configured to be extendable and contractable between the extended position and the contracted position.

    As shown in FIG. 9, the container C of the present invention is loaded and unloaded between the vehicle body 101 and the ground by a loading device 102 mounted on the vehicle body 101 of the transport vehicle 100. The loading device 102 includes a lift arm 103 pivotally supported with respect to a vehicle body, a hook arm 104 having an L-shape in side view attached to a tip portion of the lift arm 103, and A hook 105 provided at the tip of the hook arm 104, a drive cylinder (not shown) for rotating the lift arm, and a hook cylinder (not shown) for rotating the hook arm are configured. The hook 105 can be engaged with a lift bar 8 provided on the front surface of the container C. A jack 106 that can be refracted toward the front of the vehicle is provided at the rear end of the transport vehicle 100. The jack 106 is held in a storage position that is refracted forward of the vehicle when the vehicle is traveling, and is held in a protruding position that protrudes downward when the container C is loaded. A contact detection device 107 is provided on the rear end surface of the vehicle. When the contact portion 108 of the contact detection device 107 comes into contact with another member, the operation of the loading device 102 is stopped.

[Work for lowering container C at a low position on the ground from the body 101 of the transport vehicle 100]
Next, the operation of loading and unloading the container C of the present invention by the transport vehicle will be described with reference to FIGS.

    When the container C at a low position is lowered from the body 101 of the transport vehicle 100 to the ground, first, the container C is stored from the state in which the container C is mounted on the transport vehicle 100 (see FIGS. 9 and 10A). The jack 106 at the position is moved from the storage position to the extended position. At this time, the front leg HF is close to the retracted position where the front leg 15 is swung backward (see FIG. 6), and the rear leg HR is close to the lower surface of the bracket 30 and the cylindrical member 25. It is located in the contracted position (see FIG. 8). This prevents the front leg HF from coming into contact with the transport vehicle 100 and being damaged when the container C is mounted on the transport vehicle 100, and the rear leg HR contacts an obstacle on the road while the transport vehicle is running. This is to prevent damage. From this state, the hook arm 104 is rotated toward the rear of the vehicle by the hook cylinder. By this operation, the container C moves rearward of the vehicle in parallel with the vehicle body.

    Next, the lift arm 103 is rotated toward the rear of the vehicle by the drive cylinder (see FIG. 10B), and the container C is moved rearward while tilting backward. By this operation, the rear part of the container C is rotated downward, and the roller 31 is grounded.

    When the lift arm 103 continues to rotate to the rear of the vehicle and rotates to the position shown in FIG. 10C, the hook arm 104 faces downward and the container C is lowered to the ground behind the transport vehicle 100. At this time, since the front leg HF is held in the retracted position, the front leg HF is connected to the base grounding member 19 of the base leg 14 and the front leg 15 as shown in FIG. The second tip portion grounding member 23 is in contact with the ground. For this reason, since the ground contact area where the front leg portion HF is in contact with the ground is large, it is possible to prevent the front leg portion HF from being buried in the ground even when the weight of the container C is dispersed and the ground is muddy.

  Next, if the hook 105 at the tip of the hook arm 104 is removed from the lift bar 8, the container C is completely separated from the transport vehicle 100. After separation, the jack 106 in the extended position is refracted to the storage position, and the lowering operation of the container C is completed.

As described above, the container C on the transport vehicle 100 can be placed on the ground at a low position where the front leg portion HF and the rear leg portion HR are the retracted position and the retracted position, respectively. Therefore, by placing the container C after the completion of the water supply work in a storage space on the ground at a low position, the height from the ground to the manhole 10 on the upper surface of the container C is lowered, so the manhole 10 is opened at the next water supply work. Then, the work of feeding a transported object such as potable water into the tank T can be performed efficiently.
Note that the operation of loading the container C at the low place on the transport vehicle 100 from the ground is omitted because the operation of lowering the container C is performed in reverse.

[Work for lowering container C at a high position from the body 101 of the transport vehicle 100 to the ground]
When the container C at a high place is lowered from the vehicle body 101 of the transport vehicle 100 to the ground, the container C is first stored from the state where the container C is mounted on the transport vehicle 100 (see FIG. 9 and FIG. 11A). The jack 106 at the position is moved from the storage position to the extended position. At this time, the front leg HF is close to the retracted position where the front leg 15 is swung backward (see FIG. 6), and the rear leg HR is close to the lower surface of the bracket 30 and the cylindrical member 25. It is located in the contracted position (see FIG. 8).

  Thereafter, the rear leg HR is changed from the contracted position to the extended position. More specifically, the operator holds the handle 29 of the rear leg HR in the contracted position shown in FIG. As a result, the fitting between the pin 34 and the hole 26 of the cylindrical member 25 and the lower hole 33 of the sliding member 27 is released, so that the sliding member 27 slides in the height direction with respect to the cylindrical member 25. It becomes possible. In this state, the sliding member 27 is slid downward with respect to the tubular member 25, so that the upper hole 32 and the hole 26 are aligned (see FIG. 7). At this time, the position of the upper hole 32 coincides with the hole 26 when the lower surface of the lid member 28 abuts on the upper surface of the cylindrical member 25. It is possible to easily match the positions of the upper hole 32 and the hole 26 only by lowering them by their own weight. Thereafter, the pin 34 is fitted into the upper hole 32 and the hole 26. As a result, the rear leg HR can be changed / held from the contracted position shown in FIG. 8 to the extended position shown in FIG. Thereafter, the hook arm 104 is rotated toward the rear of the vehicle by the hook cylinder. By this operation, the container C moves rearward of the vehicle in parallel with the vehicle body.

    Next, the lift arm 103 is rotated toward the rear of the vehicle by the drive cylinder (see FIG. 11B). The container C is moved rearward while tilting backward. By this operation, the rear part of the container C is rotated downward.

  When the lift arm 103 continues to rotate to the rear of the vehicle and rotates until the front leg HF is positioned behind the rear bumper as shown in FIG. 11C, the rotation of the lift arm 103 is stopped. Let Thereafter, the front leg 15 of the front leg HF is changed from the retracted position to the protruding position. More specifically, the operator pulls the pin 18 of the front leg HF in the retracted position shown in FIG. 6 against the urging force of the spring, so that the pin 18 contacts the front surface of the front leg 15. Is released. Then, the front leg 15 is swung forward, and the pin 18 is fitted into the hole 17 of the base leg 14 and the hole 21 of the front leg 15 to hold the front leg HF in the protruding position. (See FIG. 6).

  Thereafter, when the rearward rotation of the vehicle by the lift arm 103 is resumed and rotated to the position shown in FIG. 11D, the hook arm 104 is directed downward and the container C is lowered to the ground behind the transport vehicle 100. It is. Next, if the hook 105 at the tip of the hook arm 104 is removed from the lift bar 8, the container C is completely separated from the transport vehicle 100. After separation, the jack 106 at the protruding position is refracted to the storage position, and the lowering operation of the container C is completed.

As described above, the container C on the transport vehicle 100 can be placed on the ground at a high position where the front leg 15 of the front leg HF protrudes and the rear leg HR extends. Therefore, when the water supply operation is performed with the container C placed on the ground, the position of the discharge port is close to the ground, and the opening of the polytank P cannot be brought close to the discharge port, thereby preventing the water supply operation from becoming difficult. be able to. In addition, since the container C can be placed on the ground at a high position, the height of the faucet 13e is increased, so that the water supply operation performed by operating the faucet 13e is facilitated.
Since the discharge port 13d at the rear of the container C can be arranged at a high place, the opening of the polytank P can be brought close to the discharge port 13d at the time of water supply, and water supply work can be performed efficiently.

[Work for loading container C at a high position on the ground onto the vehicle body 101 of the transport vehicle 100]
When loading the container C at a high position placed on the ground onto the vehicle body 101 of the transport vehicle 100, first, the lift arm 103 is rotated backward together with the hook arm 104 and rotated to the position shown in FIG. Let Thereafter, after the jack 106 is moved from the storage position to the extended position, the transport vehicle 100 is moved backward, and the hook 105 is engaged with the lift bar 8.

  Next, the hook arm 104 is rotated toward the front of the vehicle to the position of FIG. At this time, since the container front part rises, the front leg part HF of the container is in a state of floating from the ground. In this state, the front leg 15 of the front leg HF is changed from the protruding position to the retracted position. More specifically, when the operator pulls the pin 18 of the front leg HF in the protruding position shown in FIG. 5 outward against the biasing force of the spring, the hole 17 and the tip of the base leg 14 The hole is extracted from the hole 21 of the side leg portion 15, and the fitting between the pin 18 and the hole 21 of the front side leg portion 15 is released. Then, the front leg 15 is manually swung back to the retracted position. After rocking the front leg 15, the pin 18 is inserted into the hole 17 in the base leg 14 by releasing the hand from the pin 18. Thereby, since the pin 18 and the front surface of the front part side leg part 15 contact, the state which the front part side leg part 15 rock | fluctuated back can be maintained, and the front side leg part HF is hold | maintained in a retracted position. (See FIG. 6).

  If the front arm HF is not switched to the retracted position at the position of FIG. 11C and the lift arm 103 is rotated forward with the projecting position, the second front-end grounding member 23 of the contact detection device 107 Contact the contact portion 108. As a result, the operation of the loading device 102 is stopped, so that it is possible to prevent the front leg HF at the protruding position protruding from the container frame 2 from coming into contact with the vehicle body 101 and being damaged. In addition, since the front surface (surface to be grounded) of the second tip portion grounding member 23 is in contact with the contact portion 108, even if the container moves up and down when the container C is mounted on the vehicle body of the transport vehicle 100, The tip grounding member 23 and the contact portion 108 can reliably contact each other.

  Thereafter, the lift arm 103 and the hook arm 104 are rotated forward in this order, and the container C is mounted on the vehicle body 101 of the transport vehicle 100 as shown in FIG. Next, the rear leg HR is changed from the extended position to the contracted position. More specifically, the worker holds the handle 29 of the rear leg HR at the extended position shown in FIG. As a result, the fitting between the pin 34 and the hole 26 of the cylindrical member 25 and the upper hole 32 of the sliding member 27 is released, so that the sliding member 27 slides in the height direction with respect to the cylindrical member 25. It becomes possible. In this state, the sliding member 27 is slid upward with respect to the cylindrical member 25, and the pin 34 is fitted into the lower hole 33 and the hole 26 in a state where the lower hole 33 and the hole 26 are aligned. As a result, the rear leg HR can be changed and held from the extended position to the contracted position. Thereafter, the jack 106 is moved from the protruding position to the storage position. Thereby, the conveyance vehicle 100 can convey the container C.

As described above, since the container C placed on the ground can be mounted on the transport vehicle 100, the container C can be easily transported from the water supply site after the water supply operation is completed.
In addition, since the front leg HF is moved from the protruding position to the retracted position while the container C is being loaded onto the transport vehicle 100, the front leg HF does not interfere with the vehicle body 101 of the transport vehicle 100 and is not damaged. Furthermore, since the rear leg HR is moved from the extended position to the contracted position after the container C is loaded on the transport vehicle 100, it does not come into contact with an obstacle or the like on the road when the transport vehicle 100 travels.

  Further, the operation of changing the positions of the front leg portion HF and the rear leg portion HR is performed in a state where the container C is lifted by the loading device 102 during the container unloading operation. Therefore, the front leg HF and the rear leg HR are not grounded, and the position can be switched without the weight of the container C acting on the front leg HF and the rear leg HR. Therefore, the switching operation of the front leg HF and the rear leg HR can be performed manually.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the container C is a tank container that transports drinking water, but may be a container that transports powdered fluid such as granular food products or powdered chemicals. At that time, a compressor for pressurizing the inside of the tank and a power source for driving the compressor can be mounted on the container.

  Although the front leg HF and the rear leg HR can be manually operated, the positions of the front leg HF and the rear leg HR may be switched using a driving device such as a cylinder. . Even in this case, if the position of the front leg HF and the rear leg HR is switched in a state where the container is floated from the ground, the container is placed on the front leg HF and the rear leg HR. Since the position can be switched without its own weight acting, a driving device such as a cylinder can be reduced in size.

    Further, the front leg HF can be folded by the base leg 14 and the front leg 15 that can be bent with respect to the base leg 14, and the rear leg HR has a cylindrical member 25, Although it can be expanded and contracted by the sliding member 27 slidable with respect to the cylindrical member 25, the front leg HF can be expanded and contracted, and the rear leg HR can be folded. Furthermore, both the front leg HF and the rear leg HR may be either a foldable structure or a stretchable structure.
