Abstract

The invention relates to the field of lifting and transport equipment for carrying out loading and unloading operations in warehouses of trading bases, shops, workshops and other objects. The aim of the invention is to increase the reliability of the device. It contains a platform 2 suspended on the frame 1 by means of cables 3 thrown over the blocks 4 and fixed in the lower parts of the counterbalance springs 5 placed in cylindrical cases 6, in the upper parts of which the spring preload mechanisms 7 are installed. In the upper part of the frame 1, a double-acting hydraulic cylinder 15 is fixed, the piston of which is connected to platform 2 via a lever mechanism 16. The loading platform 2 is in the upper position, the hydraulic system valve is set to the closed position, and the spring 5 pressing mechanism is set to a predetermined level lowering the platform with the load. The platform 2 is loaded and the hydraulic system valve is turned to the "open" position, while the platform under the action of the mass of the load is gradually lowered to the predetermined level, compressing the counterweights springs. After unloading, the platform 2 and the lever mechanism 16 with the piston of the hydraulic cylinder are returned to their original position by the action of expanding counterbalance springs. 4 il.

Description

The invention relates to lifting and handling equipment for carrying out loading and unloading operations in trading bases, warehouses and stores using the mass of the cargo.

The purpose of the invention is to increase reliability.

Figure 1 shows the device, a general view of figure 2 - the same, side view; on fig.Z - the mechanism of a preload of a spring, a general view; figure 4 - view And fig.Z. The device comprises a frame 1, on which a cargo platform 2 is suspended by means of cables 3, thrown over blocks 4 and secured in the lower parts of springs 5 placed in lateral cylindrical housings 6. In the upper parts of the latter, mechanisms 7 for preloading springs 5 an anvil 8 connected by axles 9 with gears 10 and a handle 11 "Gears 10 are meshed with a rack 12 installed in the housing cavity b. Outside the latter, a frame 13 with a vernier and a scale of 14 spring preload 5, fixed in the levels of lowering and lifting the load, are fixed on the axis x 9. A hydraulic cylinder 15 of double action is fixed on the upper part of the frame 1, the piston of which is connected to the loading platform 2 via a lever mechanism 16,

The device works as follows.

The load platform 2 is in the upper position, the hydraulic valve is set to the Closed position, and the springs 5 are preloaded by turning the handle 11 to the required lowering of the platform 2. On the platform 2, containers or other loads are loaded from the vehicle or from the ramp

warehouse Then, the hydraulic system valve is set to the Open position, and under the action of the weight of the load the platform is lowered smoothly down to the predetermined height on the spring counterweights. The smoothness of the platform run is controlled by the degree of opening of the hydraulic system valve. After unloading the containers, the platform 2 under the action of the springs 5 rises to the upper initial position, and the hydraulic system with a lever mechanism also comes to its initial position.

Claims (3)

1. A loading and unloading device containing a loading platform suspended on a frame, connected by a cable-and-block system with counterweights and connected to a double action hydraulic cylinder piston mounted on a frame, characterized in that, to improve reliability, the counterweights are made in the form of cylindrical springs, the lower parts of which are connected to the platform by cables thrown over the blocks, and spring mechanisms are installed in the cases above their upper parts,
2. The device according to claim 1, about tl and the fact that the spring-pull mechanism is designed as an emphasis connected by axles with gears interlocking with each other,
| And one gear meshed with the rack housing.
3. A device as claimed in Claims 1 and 2, characterized in that the piston of the hydraulic cylinder of the hydraulic system is connected to the load platform through a lever mechanism.
