DETAILED DESCRIPTION OF THE INVENTION The present invention provides for movably supporting a carrier on an elevating body equipped with an elevating drive wheel or a meshing gear that engages in rotation with a horizontal member of an elevating guide support that constitutes an elevating guide rail. The present invention also relates to an elevating and lowering transport device that can continuously move horizontally and keep the upper surface of the carrier horizontal at all times to effectively transport articles.

Conventionally, as is well known, in devices for lifting and transporting goods, handling in the vertical direction and handling in the horizontal direction are carried out separately.Elevators, lifts, etc. are especially used for transporting materials at construction work sites, etc. Vertical transportation is carried out using a lifting device, and this is transported to the required work floor using a hand truck or a hand truck.
Horizontal transportation is carried out using conveyors, oak lifts, etc., and at the intersection of vertical transportation and horizontal transportation, relay work is performed manually or with various types of power transportation equipment. In this respect, it is very inconvenient and is one of the factors that hinders the improvement of work efficiency.

Therefore, there has been a long-awaited desire to create a transportation system that can continuously shift from vertical transportation to horizontal transportation, but this has not been easy as the drive method would be significantly different.

In view of the current situation, the present invention has been developed to carry out vertical transportation and lateral transportation, which were difficult to solve in the past, by using a single carrier along a series of guide rails to transport various materials and other items, for example, on the ground. It is possible to freely move and transport it continuously, either horizontally or in an inclined position after rising from the ground to the appropriate position at a high place, and this movement can be carried out without any difficulty. It is an object of the present invention to provide an elevating and lowering transport device having a structure in which the article-receiving surface of the carrier can be moved in a horizontal state at all times with respect to the elevating and lowering frame.

That is, the present invention provides a guide rail in which a large number of interlocking horizontal members are arranged at a predetermined pitch between two pairs of longitudinal members each having a guide portion on the outer side, with the longitudinal members arranged on the left and right sides. The upright part and the lateral moving part are supported by a structure, etc., and are arranged continuously with a curved part interposed therebetween, or are appropriately inclined, and such guide rails are arranged in two rows in parallel at appropriate intervals, and each guide rail is arranged in parallel at appropriate intervals. Each row of guide rails is equipped with an elevating frame through two sets of front and rear movable roller support legs in which guide rollers engage with guide portions of the rails, and each elevating frame has a horizontal member of the guide rail on its upper part. A carrier support shaft is provided at a suitable location in the lower half of the lifting frame to protrude to the side, and the center is supported by the protrusion of the support shaft. The peripheral edge of the support attached to the lower part of the lifting frame is auxiliary supported by a roller, and a support plate of an appropriate diameter is provided, and the support plate is placed between a pair of lifting frames arranged so that the support plates face each other. A carrier is mounted so that the interval can be adjusted via a fixed support, and a movable rod end of an electric reciprocating body pivotally connected at the intermediate portion via a support piece fixed to the end of the support shaft is attached to one end of the support plate. The electric reciprocating body is connected to the upper part of the bracket that is fixed upright to the guide rail, and is associated with an electric control mechanism that operates the electric reciprocating body to maintain the carriage horizontally at all times between the carriage and the guide rail.

The guide rail used is one in which a number of horizontal members made of steel plates, one or two of which have approximately circular arc surfaces, can be formed integrally with a set pinch between a pair of longitudinal members with guide grooves formed on the outside. The gear attached to the lifting frame includes an impeller having a plurality of arms each having a roller at its tip with a circumferential pinch matching the horizontal member pinch of the guide rail, and an L.
(1) A roller is adopted in which the roller engages with the above-mentioned horizontal member in a rolling manner.

In addition, instead of the above-mentioned guide rail, a guide rail in which a horizontal member with a circular cross section is arranged at the required pinch between a pair of longitudinal members with guide grooves formed on the outside can be used, and it can be used as a gear attached to the lifting frame.

At the same time, when the carrier 40 is lifted up and ascends along the guide rail, the supporting legs 25, 25' are supported by the flange portion of the vertical member 1107 forming the guide groove 13 of the guide rail 10, as shown in FIG. The guide adder 25'' is guided, and the impeller 260 row 2 is guided as described above.
21 and the arcuate surface 12' of the horizontal member 12 is ensured, and the connecting portion between the carrier 40 and both lifting frames 20 is in a normal state and the carrier is raised while being kept horizontal.

When the curved rail 16 is reached, the elevating frame 20
In the guide groove part of the rail 16, each guide roller 25'',
25" is guided and gradually tilts while maintaining the rolling engagement between the impeller 26 and the rail horizontal member 1T, and the seven elevating frames 20
When a detector installed near the °C guide rail (for example, a mechanically operated switch, a non-contact switch, a photoelectric switch, etc.) detects the progress of the elevating frame 20 immediately before the elevating frame 20 starts tilting, the electric motor mounted on the elevating frame 20 When the activation signal is given to the reciprocating drive body 36 and the operating rod 36' of the reciprocating drive body 36 is retracted according to the moving speed of the elevating frame set in advance by the electric controller, the operating rod 36' is moved as shown in FIG. 36' retreats, the distance t between the connecting pin 31 at the end of the bracket 34 and the position of the pivot pin 35' by the seven-piece piece 35 of the reciprocating drive body 36 gradually decreases, and the lifting frame 20 is supported even though it is tilted. The supporting pieces 33, 33 provided on the upper part of the board 30 always maintain an upward position, so that the carriers 40, which are mounted and connected to each other via the supporting pieces 33 and by the buffer bodies 43, remain horizontal. During the transition of only the lifting frame 20 from the upright part to the horizontal part, about 9
The support plate 30 is displaced through the 0° support shaft 23, and during this time, the support plate 30 rotates easily with respect to the outer edge 30' due to the engagement between the flanged sockets 231 and 31 attached to the lower end of the lifting frame 20 and the outer edge 30'. However, even when moving to the horizontal area, the upper surface of the carrier 40 is kept horizontal and only the elevating frame 20 remains tilted as it moves to this section.

By fixing the row 2 support leg 25', which supports the main body to the support shaft 23 during curved displacement, to the shaft 23, the guide roller 25'' rolls along the curved section rail 16. At this time, rotational force is applied to the support shaft 23 in response to the guide, and the reciprocating drive body 3 is rotated through the fork piece 35.
6 and the guide row 225'' attached to the support leg 25 attached to the drive shaft 21 side, the elevating frame can be stably held and displaced.

When the elevating frame 20 moves from the upright section to the horizontal section in this way, the carrier 40 mounted between the two elevating frames 20 and 20 maintains its posture in the upright elevating section as shown by the broken line A in FIG. Up to, the impeller 2 attached to the lifting frame 20
The row 227 of No. 6 engages with the horizontal member 15 of the horizontal section rail 14 and moves by .degree.

When the plane has passed through the curved guide rail 16, the platform horizontal control command by the detector provided near the guide rail at the relevant position is completed, and the reciprocating drive body 36 is activated by the command.
The operation of is stopped and the state of 1 is maintained.

Therefore, if you move to a desired position and stop the drive motor, you can easily stop at any position and unload or load articles placed on the carrier. The included control device and the built-in stabilizing device act to stop the impeller from rotating, and the elevator stops without moving, so there is no problem in any position from the horizontal to the upright section. do not have.

After transporting the goods etc. to the required level such as the above-ground area,
In order to return the elevating frame and the carrier to their original positions or to a high place at the bottom, the two-part motor M of the elevating and descending seven frames is reversed so that the impeller 26 moves freely and the reciprocating drive body 36 moves at the curved portion of L1. The operating rod 36' moves forward in the opposite direction to the above, so that the carrier can be moved while keeping it horizontal at all times.

Also, both guide rails 10, 10, 13, 13, and 14
．． 14 Even if the spacing is slightly inconsistent, 7 frames 20
and the carrier 40 are the rows 2 that can roll on the supporting pieces 33.
42 and in cooperation with the buffer body 43, deviations in the rail spacing can be automatically corrected, and smooth operation can be achieved without causing any deviation in the progress of the seven left and right vertically moving frames.

In the device of the present invention, as explained in the above embodiment, the elevating frame moves up and down along the guide rail having the horizontal members arranged at the required pinch to connect the pair of left and right vertical members serving as guide parts. A drive wheel (impeller, or a tooth-shaped gear whose horizontal member has a circular cross section and meshes with it) mounted on the elevating frame.
By meshing with the horizontal member, the reaction force at the time of vertical movement is supported by the horizontal member, and two pairs are provided at the front and rear of the guide portion of the guide rail at the front and rear positions of the meshing portion and at appropriately distant positions. The guide rollers are in contact with each other and guided and supported, and the elevating frame is moved via the two sets of support legs that support the guide row 2, so that the guide rails are not connected to the linear part. Even if it is combined with a curved part, it can be moved and operated without any problems.

As an elevator, the device of the present invention moves continuously three-dimensionally from an upright section to a curved section to a horizontal section. The carrier can be moved up and down while automatically adjusting the deviation between the pair of guide rails and always maintaining a horizontal state.
At the curved section, the lift frame is guided by the guide rail by the operation of the reciprocating drive body, and the lift frame is guided by the guide rail, and the lift frame is guided by the guide rail, and the lift frame is guided by the guide rail.The lift frame is guided by the guide rail, and the lift frame is guided by the guide rail. By interposing L, this support plate is stably supported on the lifting frame side so that it can rotate, and the carrier is mounted on such a support plate, making it possible to carry out smooth three-dimensional transportation. As a result, it was necessary to transport materials for construction work from the above-ground part to the appropriate upper part of the structure, or to transport materials and soil between the underground and above-ground parts via a shaft, and other lifting and lateral movements. As a result, the combined conveyance work can now be carried out continuously, making it possible to streamline the work in a way that was previously unforeseen.

In addition, according to the spirit of the present invention, from the upright section to the inclined section,
Further, it is also possible to arbitrarily carry it up and down in a horizontal section with an inclined section and a curved section, or in an inclined state.
