Description

[Detailed description of the invention] The present invention relates to a transport vehicle for transporting drums, and includes a master cylinder that raises an elevating plate that is secured to a mast that is set up on a movable trolley and has a handle on the top. In a structure comprising a plunger pump to be driven and a pumping handle for operating the same, an elevating plate pole is erected and fixed on one side of the elevating plate, a drum can holder is connected to the lower end of the elevating plate pole, and a clamp is attached to the upper end of the elevating plate pole. A lower drum receiving claw having a roller on the plate is rotatably fixed via a fulcrum shaft, and an upper drum receiving claw whose one end is brought into contact with the roller of the lower claw above this is attached to the mounting plate via the fulcrum shaft. The device is rotatably fixed to the drum and configured to transmit the receiving force of the lower claw to the upper claw via the roller, so that the drum can be lifted with the receiving force of the upper and lower claws proportional to the weight of the drum. By locking, it is possible to securely lock the drum and prevent the drum from coming off from the upper and lower claws when going up and down or moving.Also, there is no need for links, etc., and the drum can is locked only by the upper and lower claws via rollers. Therefore, it is an object of the present invention to provide a drum transport vehicle with an elevator that has a simple structure and can be manufactured at low cost, thereby reducing costs.

2 and vertically stored in contact with the shaft 2.
By rotating only the pumping handle 21 around 2, locking it with the stopper 33, and pushing down the horizontally protruding pumping handle 21 with a foot operation, the lever member 17
The handle 21 is integrally swung to operate the pump 15 and drive the hydraulic cylinder 13.

As shown in FIGS. 6 to 8, the elevating plate 10
A lifting plate pole 34 is connected and fixed to the pole 3.
A drum receiver 35 is integrally connected to the lower part of 4.
At the top of the pole 34, a clamp mounting plate 36a,
36b via the fulcrum shaft 37, and the drum A
A lower claw 38 that is engaged with the lower surface of the upper edge B from below is formed at one end of a support claw 39 that is a drum receiving lower claw, and the middle of the support claw 39 is attached to the clamp mounting plates 36a, 36b with a fulcrum shaft 40. The roller 4 is rotatably supported via the supporting claw 39, and the roller 4
1 is pivotally supported via a roller shaft 42.

The base end of the movable claw 43, which is the drum receiving upper claw against which the roller 41 abuts, is fixed to the clamp mounting plate 36.
a, 36b via a fulcrum shaft 44, and an upper claw 45 is formed at the tip of the movable claw 43 to engage with the inner surface of the upper edge portion B of the drum can A. A roll pin 4
A spring 48 is tensioned via the springs 6 and 47.
Thus, the roller 41 is supported in contact with the movable claw 43. A stopper 49 is attached to the clamp mounting plates 36a, 36b so as to abut against the upper portion of the pole 34 and restrict the forward and backward tilt of the clamp mounting plates 36a, 36b.
36b, and further connected and fixed to the clamp mounting plate 36
A locking pin 5 is provided between the pole 34 and the a, b
A spring 52 is tensioned via the clamp attachment plates 36a and 36b, and the spring 52 supports the clamp attachment plates 36a and 36b in a forward inclined manner.

The present invention is constructed as described above, and when the lower claw 38 is brought into contact with the side surface of the drum A, the clamp mounting plates 36a and 36b resist the spring 52, as shown by the imaginary line in FIG. The stopper 49 is displaced backward by the regulated width, and the upper claw 38 is supported in contact with the side surface of the drum A. In the above state, when the pumping handle 21 is tilted and operated by foot to drive the hydraulic cylinder 13 and lift the lift plate pole 34 via the lift plate 10, the lower claw 38 touches the lower surface of the upper end B of the drum. The support claw 39 is engaged from below, and at the same time the support claw 39 rotates around the fulcrum shaft 40 due to the weight of the drum A, the roller 41 of the support claw 39
The movable claw 43 is rotated around the fulcrum shaft 44, and the upper claw 45 at the tip of the movable claw 43 is engaged with the inner surface of the upper edge B of the drum from above, and the lower claw 38 and the upper claw 45 Then, lift the drum A by grasping the upper edge B of the drum. On the other hand, when moving the lifted drum A to a predetermined position and lowering it as described above, when the hydraulic cylinder 13 is moved back by operating the pressure relief valve 16 to drain the pressure oil, the lifting plate pole 34 is lowered. The lower claw 38 separates downward from the upper edge B of the drum, the roller 41 separates from the movable claw 43, the upper claw 45 is lifted upward by the connection of the spring 48, and the lower claw 38 and the upper claw 45 move toward the upper end of the drum. Move away from edge B.

As shown in the embodiments described above, the present invention is based on a plunger that drives a master cylinder 12 that lifts a lifting plate 10 by locking an elevating plate 10 to masts 6, 6 which are set up on a movable cart 5 and having a handle 7 on the upper part. In a structure including a pump 15 and a pumping handle 21 for operating the same, the elevating plate 10
An elevating plate pole 34 is erected and fixed on one side, a drum receiver 35 is connected to the lower end thereof, and a lower drum receiver claw such as a support claw 39 equipped with a roller 41 is attached to the clamp mounting plates 36a and 36b provided at the upper end. A drum can receiving upper claw such as a movable claw 43 which is rotatably fixed via a fulcrum shaft 40 and whose one end is brought into contact with the roller 41 of the lower claw 38 above the movable claw 43 is attached to the mounting plate 36a via a fulcrum shaft 44. , 36b, and transmits the receiving force of the lower claw 38 to the upper claw 45 via the roller 41,
By locking the drum A with the receiving force of the upper claw 45 and the lower claw 38 proportional to the weight of the drum A, the drum A is reliably locked and the drum A is removed from the upper and lower claws 38, 45 during elevation and movement. It is possible to prevent the separation of the parts, and since it is locked only by the upper and lower pawls 38 and 45 via rollers without the need for links, the structure is simple and the manufacturing cost can be reduced, making it extremely practical. It has remarkable effects such as being effective.
