Loading and unloading assisting device

Abstract

The invention provides a loading and unloading assisting device and relates to the technical field of loading and unloading machinery. A rack adopts an H-shaped structure, ground columns are arranged at left and right ends of a cross beam of the rack, vertical sliding chutes I matched with first sliding blocks are formed at upper half parts, pulleys are arranged at lower ends, horizontal sliding chutes are formed in side surfaces of the middles of the vertical chutes I, and horizontal second sliding blocks matched with the horizontal sliding chutes are arranged in the horizontal sliding chutes; a pair of columns with vertical sliding chutes II is arranged on the inner side of the cross beam, and third sliding blocks matched with the vertical sliding chutes II are fixedly connected with pneumatic springs; one end of each connecting rod III is hinged to the corresponding vertical first sliding block, and the other end is hinged to the upper end of a corresponding connecting rod I; one end of each connecting rod IV is hinged to the middle of the corresponding connecting rod III, the hinged end of the other end of the connecting rod IV and a corresponding connecting rod II is hinged to the corresponding horizontal second sliding block, and the other end of each connecting rod II is hinged to the corresponding correcting rod I; the lower end of each connecting rod I is hinged to the middle of the side surface of a flat plate; one end of each wire cable is fixedly connected with a balancer, and the other end winds around the corresponding pulley to be fixedly connected with the corresponding vertical first sliding block. The loading and unloading assisting device is mainly used for loading and unloading assistance.

Description

technical field [0001] The invention relates to the technical field of loading and unloading machinery, in particular to a loading and unloading device in logistics transportation. Background technique [0002] During the transportation of express cartons, it is usually necessary to move the cartons from the ground to the transport vehicle, and when they reach the destination, the cartons need to be transported from the transport vehicle to the ground. Carton loading and unloading is a very important part of the transportation process; however, the existing loading and unloading methods require a lot of manpower and high labor costs. At the same time, the handling takes a long time, and the handling method is not standardized enough, which may easily cause damage to the box. There is another loading method, first stack the boxes on the pallet, then lift the pallet to a certain height with a lifting machine, and then push the boxes into the car. The unloading process is the...

AI Technical Summary

Problems solved by technology

[0004] The technical solutions of the above-mentioned two kinds of power-assisted loading devices have shortcomings. The device of the first technical solution needs to adjust three fastening clips to control the lifting height, and the operation is complicated; Poor versatility; and not suitable for repetitive operations

The device of the second technical solution is bulky and is affected by terrain factors; it is expensive and not easy to promote in small logistics points; the operation method is rigid and must be used with pallets
