a loading and unloading device

Abstract

The invention provides a loading and unloading device, which includes a driving mechanism and one or more pick-and-place units arranged side by side in the left-right direction and driven by the drive mechanism to move in the up-down direction and the front-back direction. The pick-and-place unit includes a main support arm , the main support arm is spaced apart in the front and rear direction with two stop arms extending up and down, and the two stop arms and the main support arm together form a support arm that accommodates and holds up the three-dimensional shelf when the main support arm moves from bottom to top U-shaped storage tank for stored pipe or bar stock. The loading and unloading device of the present invention is simple in structure, easy to operate, can conveniently realize the loading and unloading of pipes or bar parts on the multi-layer three-dimensional shelf, is safe and reliable, greatly improves the loading and unloading efficiency, and reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to a loading and unloading device suitable for loading and unloading pipe or rod parts. Background technique [0002] With the rapid development of power transmission and transformation projects, high-voltage isolating switches have been widely used in large numbers. In the high field isolation switch, the transmission movement of the switch in the process of opening and closing is realized by the mutual linkage of the vertical connecting rod and the horizontal pull rod, which plays a very important role in the whole working process. The vertical connecting rods and horizontal tie rods are generally made of steel pipes, so the usage of steel pipes is very large. In order to save space when these steel pipes are stored in the warehouse, they are generally stored on three-dimensional shelves with upper and lower layers. like Figure 1-2 As shown, the three-dimensional shelf 3 includes uprights 33 arranged opposite to each other.

AI Technical Summary

Problems solved by technology

Although this kind of three-dimensional shelf can store a large number of steel pipes in a small space, it is very inconvenient when loading and unloading steel pipes. Interference occurs, and in serious cases, the three-dimensional shelf will be overturned in the forward and backward direction, and the manual loading and unloading will greatly increase the labor intensity of the workers, the loading and unloading time is also longer, and the work efficiency is low.
