Problems solved by technology
The drag chain in the equipment, due to long-term bending back and forth, will produce debris, dust, etc. due to wear and tear, etc., these debris, dust, etc. will pollute the clean room, thereby reducing the quality of the product
[0003] In order to solve the problems of drag chains such as debris and dust due to wear and tear, among the related technologies, dust-free drag chains are usually used in equipment in clean workshops. Known dust-free drag chains usually need to add a load-bearing chain in the sheath. However, , most of the known dust-free drag chains carry weight through the joints between the chain links, and the load-bearing strength is not enough. When the movement distance is long, it is easy to collapse

The invention discloses a bearing chain, a drag chain and a dust-free drag chain. The bearing chain is used for bearing the drag chain. The bearing chain comprises a bearing base band which can be bent in the length direction, and a chain link group arranged on the bearing base band and provided with a plurality of first chain links and second chain links, wherein the first chain links are installed on the bearing base band, can float relative to the bearing base band and are distributed in the length direction of the bearing base band, the second chain links are distributed in the length direction of the bearing base band, each second chain link is connected with the two corresponding adjacent first chain links and can float relative to at least one of the two corresponding adjacent firstchain links, and when one part of the bearing base band is in a bent state, the second chain link located at the bent position of the bearing base band pulls the two corresponding first chain links connected with the second chain link. According to the bearing chain, due to the fact that the bearing base band used for installing the first chain links is arranged, the bearing strength of the bearing chain can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of cable protection, in particular to a carrying chain, drag chain and dust-free drag chain. Background technique [0002] Drag chains are widely used in various automation equipment to protect the cables (such as cables and air pipes) of the equipment and prevent them from breaking and entanglement. In manufacturing industries such as pharmaceuticals, microelectronics, and medical devices, it is usually necessary to produce related products in a clean room. The drag chain in the equipment, due to long-term bending back and forth, will produce debris, dust, etc. due to wear and tear, etc., these debris, dust, etc. will pollute the clean room, thereby reducing the quality of the product. [0003] In order to solve the problems of drag chains such as debris and dust due to wear and tear, among the related technologies, dust-free drag chains are usually used in equipment in clean workshops. Known dust-free dra...
