Abstract
Description
Technical Field
[0001] This utility model relates to the field of heavy-duty cable chain technology, and in particular to a durable and reinforced heavy-duty cable chain. Background Technology
[0002] A cable chain is a device used to secure cables, air hoses, and oil pipes, facilitating their rotation or linear movement with equipment. By wrapping these components, the cable chain prevents them from being subjected to external forces such as friction, collision, and tension during equipment movement, thus reducing the risk of wear, breakage, and damage. Furthermore, the cable chain keeps cables and pipes organized, avoiding entanglement and cross-linking that could lead to malfunctions and safety hazards, thereby improving the stability and reliability of the equipment.
[0003] In many applications, cable chains carry heavy cables and conduits with long travel distances, frequent movements, and operate in harsh environments. This places high demands on the cable chain's material strength, load-bearing capacity, and service life. Simultaneously, to complement equipment usage, the cable chain itself must be compact, lightweight, and operate smoothly and flexibly. Therefore, cable chain manufacturers are actively seeking breakthroughs in the cable chain's structure, using excellent and unique structural designs to solve problems, thus driving continuous progress and development in cable chain technology.
[0004] Currently, cable chains used in heavy-duty applications often experience chain breakage after a period of use due to uneven stress, accelerated wear, and stress concentration, resulting in the plastic-made shaft. Chain breakage can significantly impact the main equipment, potentially causing cables and pipes to jam, break, or snap, leading to equipment downtime, inoperability, or even serious safety accidents. Therefore, this application provides a durable, reinforced, heavy-duty cable chain to meet this need. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a durable and reinforced heavy-duty cable chain to solve the problem that existing cable chains used in heavy-duty applications break after a period of use due to uneven stress, increased wear, stress concentration, etc., resulting in the breakage of the plastic shaft.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a durable and reinforced heavy-duty cable chain, comprising multiple chain plate bodies connected end to end and an axial mounting assembly for connecting the multiple chain plate bodies. One end of each chain plate body is provided with a first connecting groove, and the other end of each chain plate body is provided with a second connecting groove corresponding to the first connecting groove. A chain plate rotatable countersunk hole is fixedly provided in the second connecting groove. A chain plate rotatable fitting shaft is fixedly provided in the first connecting groove and rotatably inserted into the chain plate rotatable fitting countersunk hole. The axial mounting assembly includes a first bolt and a second bolt connected to each other.
[0007] Optionally, both ends of the chain plate body are equipped with protruding plates, and both the first connecting groove and the second connecting groove are provided with hollow grooves.
[0008] Optionally, the inner wall of the first connecting groove is fixed with a protrusion, and the side wall of the second connecting groove is provided with a receiving groove.
[0009] Optionally, the protrusion is embedded in the receiving groove, and the protrusion is rotatably disposed within the receiving groove.
[0010] Optionally, mounting posts are embedded and fixed in the inner wall of the countersunk hole of the chain plate and the rotating shaft of the chain plate, and the outer wall of the chain plate body is provided with a groove corresponding to the mounting post.
[0011] Optionally, both the first bolt and the second bolt are embedded in the groove, and the first bolt is fitted into the mounting post.
[0012] Optionally, the first bolt has a threaded hole on its side wall, and the second bolt has a threaded rod connection part that is threaded into the threaded hole.
[0013] Compared with the prior art, this utility model has at least the following beneficial effects:
[0014] In the above solution, a chain plate rotating engagement shaft and a chain plate rotating engagement countersunk hole are respectively provided in the first connecting groove and the second connecting groove. The chain plate rotating engagement shaft is rotatably inserted into the chain plate rotating engagement countersunk hole. The chain plate rotating engagement shaft supports the connection of the chain plate body, thereby improving the connection strength of the chain plate body. At the same time, a first bolt and a second bolt are embedded in the mounting column. The threaded connection part of the second bolt is threaded into the threaded hole and fixed with the first bolt. By replacing the plastic connecting shaft with the first bolt and the second bolt, the connection strength of the chain plate body is further improved, and the situation of chain plate breakage due to excessive axial tensile force is reduced.

The axial mounting assembly includes a first bolt 10 and a second bolt 12 that are connected to each other.
[0029] Both ends of the chain plate body 1 are equipped with protruding plates 2. The first connecting groove 3 and the second connecting groove 8 are both provided with hollow grooves 9. The inner wall of the first connecting groove 3 is fixed with a protrusion 5. The side wall of the second connecting groove 8 is provided with a receiving groove 7.
