Description

a loading and unloading device

technical field

The invention relates to a loading and unloading device suitable for loading and unloading pipe or rod parts.

Background technique

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. As shown in Figure 1-2, the three-dimensional shelf 3 includes uprights 33 arranged opposite to each other. The uprights 33 are respectively symmetrically provided with support arms 31 extending forward and backward on the front and rear sides of the uprights. Form a multi-layer structure, the corresponding support arms 31 on the left and right columns 33 are used to support the two ends of the steel pipe 9 respectively, and the end of the support arm 31 away from the column 33 is provided with a stop for preventing the steel pipe 9 from breaking away from the support arm 31. For the rod 32, for the convenience of the following description, the distance between the column 33 and the blocking rod 32 is defined here as the storage width. 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 when it is serious, it will cause the three-dimensional shelf to overturn 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.
