Support loading and unloading device

Abstract

The invention discloses a support loading and unloading device, and belongs to the field of support transporting cars. In order to solve the technical problem, the support loading and unloading device is provided, traction oil cylinders cooperate with steel wire ropes to drag a support, and therefore loading and unloading operations are completed. Rollers are additionally arranged on a support supporting plate to reduce friction force between the support and a support transporting car. According to the technical scheme for solving the technical problem, the support loading and unloading device comprises a U-shaped frame and the support supporting plate, the support supporting plate is located between two side walls of the U-shaped frame, and the support to be loaded is arranged on the support supporting plate; the traction oil cylinders are arranged on the two side walls of the U-shaped frame and arranged in the directions of the side walls of the U-shaped frame, pulleys are arranged on the movable ends of the traction oil cylinders, and the steel wire ropes for dragging the support are wound around the pulleys; and one end of each steel wire rope is fixed to the corresponding side wall of the U-shaped frame, the other end of each steel wire rope is arranged on the support, and support unloading pulleys are arranged on the inner sides of the upper surfaces of the side walls of the U-shaped frame. The support loading and unloading device can be widely applied to the field of the support transporting cars.

Description

technical field [0001] The device for loading and unloading a bracket of the invention belongs to the technical field of frame transport vehicles. Background technique [0002] The frame needs to be realized by the frame truck during the transfer transportation process, and how to place the frame stably on the frame frame car, and then get off the car smoothly is a common problem. The traditional frame transport method is flat car rail transportation , rubber-tyred frame trucks, and hoisting crawler trucks. The problem with the hoisting type trucks in the prior art is that it is difficult to hook the front end, that is, when the bracket is on the car, it needs to be lifted by the chain. Decoupling phenomenon, and when hooking, it is necessary to manually enter the inside of the frame transport vehicle to connect the frame transport vehicle and the bracket through a chain, so there is a great potential safety hazard, and when the bracket is lifted, due to the softness of the ...

[0002] The frame needs to be realized by the frame truck during the transfer transportation process, and how to place the frame stably on the frame frame truck, and then get off the car smoothly is a common problem. The traditional frame transport method is flat car rail transportation , rubber-tyred frame trucks, and hoisting crawler trucks. The problem with the hoisting type trucks in the prior art is that the front end is difficult to hook. Decoupling phenomenon, and when hooking, it is necessary to manually enter the inside of the frame transport vehicle to connect the frame transport vehicle and the bracket through a chain, so there is a great potential safety hazard, and when the bracket is lifted, due to the softness of the chain, in the The bracket swings greatly during the lifting process

[0003] Although the shovel-type loading method used in the prior art overcomes the instability of the hoisting-type loading method, it also brings the problem of long travel distance for traction and high friction, and the need to add a special mechanism for unloading
