Classification and structural characteristics of steel drag chains

Classification and structural characteristics of steel drag chains:

Steel drag chains are used on cables, oil pipes, gas pipes, water pipes and air ducts of machine tools and machinery for traction and protection. The use of steel drag chains originated in Germany, and later the structure was introduced and innovated in China. Now the steel drag chain has been widely used on machine tools, which protects the cables and makes the machine tools look more beautiful as a whole. Steel drag chains are divided into three types: bridge steel drag chains, fully enclosed steel drag chains, and semi enclosed steel drag chains according to the use environment and use requirements.

Structure of steel drag chain:

1. The steel drag chain looks like a tank chain and is composed of many unit links, which rotate freely.

2. The inner height, outer height and pitch of the same series of steel drag chains are the same, and the inner height and bending radius r of the drag chain can be selected differently.

3. The unit chain link is composed of left and right chain plates and upper and lower cover plates. Each section of the steel drag chain can be opened, which is convenient for assembly and disassembly without threading. After opening the cover plate, the cable, oil pipe, gas pipe, etc. can be put into the drag chain.

4. In addition, separators can be provided to separate the space in the chain as required.
