Description

Technical Field

[0001] This utility model belongs to the field of cable drag chain technology, and in particular relates to an industrial cable drag chain. Background Technology

[0002] As a key component specifically designed to accommodate and protect cables and adapt to the movement trajectory of equipment, industrial cable drag chains must simultaneously meet the requirements of cable protection and flexible dragging. They must prevent problems such as cable sheath damage and signal interruption caused by friction, collision, and entanglement during the reciprocating motion of equipment, while also ensuring that the drag chain itself can bend at multiple angles and move over long distances with the equipment, and is easy to disassemble and maintain, so as to adapt to complex industrial operation scenarios.

[0003] Chinese patent application CN213585043U discloses a telescopic arm cable drag chain, including chain links. Each chain link has a protective plate at both ends. A cable placement mechanism is located inside each chain link. The protective plate has a mounting groove on its surface, and a fixing mechanism is located inside the mounting groove. The cable placement mechanism includes a mounting cylinder inside the chain link, with a threaded cylinder penetrating through the mounting cylinder. This invention allows for easier fixing and splicing of chain links, greatly improving the work efficiency of users. It also provides placement and protection for cables, preventing damage or breakage during transport. Furthermore, it allows for the transport and protection of multiple cables, accelerating work efficiency.

[0004] The above-mentioned fixing method using arc-shaped clamps and threaded rods has the following drawbacks when it is necessary to accommodate cables of different specifications: either the spacing is too large, causing the cables to shake inside the cable chain and collide and rub against the inner wall of the cable chain or other cables; or the spacing is too small, causing the cables to be excessively squeezed. After long-term use, problems such as outer sheath wear and internal conductor damage will occur. It lacks elastic adjustment capability and cannot adapt to the mixed laying needs of multiple specifications and quantities of cables in industrial scenarios.

[0005] To address these issues, we provide an industrial cable drag chain. Utility Model Content

[0006] The purpose of this utility model is to provide an industrial cable drag chain that, through the cooperation of connecting blocks and adjustment mechanisms, solves the problem that existing cable drag chains lack elastic adjustment capabilities and cannot adapt to the mixed laying needs of multiple specifications and quantities of cables in industrial scenarios.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an industrial cable drag chain, comprising a section plate, a connecting block fixedly connected to one side of the section plate, and an adjustment mechanism provided on one side of the connecting block. The adjustment mechanism includes a connecting post, one side of which is fixedly connected to the connecting block. Threaded posts are fixedly connected to the top and bottom of the connecting post. A connecting plate is fitted onto the surface of the threaded post, and a fastening nut is threadedly connected to the surface of the threaded post on one side of the connecting plate. Both sides of the connecting plate are in contact with the section plate. The two threaded posts are symmetrically distributed, providing bidirectional balanced support and positioning points for the connecting plate. The connecting plate slides freely along the axial direction of the threaded posts to adjust according to actual needs. The installation position can be adjusted as needed. By tightening the nuts and threaded posts, the connecting plate is locked in the preset position, preventing positional displacement due to vibration or other factors during use. Both sides of the connecting plate are in contact with the section plate, forming a surface contact fit. This not only improves the stability of the connecting plate after installation but also limits radial sway of the connecting plate through the contact surface fit. The connecting plate slides freely along the threaded posts. Combined with the locking function of the tightening nuts, the installation position of the connecting plate can be flexibly adjusted to adapt to the installation requirements of different cable specifications or the assembly scenarios of different equipment. Multi-scenario adaptation can be achieved without replacing the entire component, improving the versatility of the cable chain.

[0009] The present invention is further configured such that a cable fixing mechanism is fixedly connected to one side of the connecting plate. The cable fixing mechanism includes a fixing plate, one side of which is fixedly connected to the connecting plate. A spring sleeve is fixedly connected to one side of the connecting plate, and a positioning block is fixedly connected to one side of the spring sleeve. A positioning groove is provided on the top of the positioning block. The position adjustment of the connecting plate is synchronized with the cable laying requirements to avoid the cables being randomly distributed inside the cable carrier. The elastic characteristics of the spring sleeve give the positioning block an adaptive clamping ability, which flexibly adjusts the clamping force according to the outer diameter of the cable, preventing the cable from loosening and shifting, and avoiding cable damage caused by excessive compression. The positioning groove provides a space for the cable, realizing the orderly separation of single or multiple cables, reducing friction between cables, and ensuring stable signal transmission and cable life.

[0010] The present invention is further configured such that there are three positioning slots, which are equidistant from each other. The three positioning slots enable the independent placement of the three cables, avoiding friction and wear or signal interference caused by the mixing and contact of multiple cables. This is especially suitable for the separate laying of power cables and signal cables.

[0011] The present invention is further configured such that there are two section plates, which are symmetrically arranged. Both sides of the surface of each section plate are provided with connecting holes. The two symmetrically arranged section plates form a symmetrical clamping structure, which provides balanced support and protection from both sides of the cable, avoids deformation of the cable chain or cable deviation caused by unilateral force, improves the overall structural strength of the cable chain, and the symmetrical design makes the cable chain more evenly stressed during bending and dragging, reduces local stress concentration, and extends the fatigue life of the cable chain.

[0012] The present invention is further configured such that the spring sleeve includes a sleeve body, an internal spring, and a telescopic column. The sleeve body is fixedly connected to a fixing plate. The internal spring is disposed inside the sleeve body. One end of the telescopic column abuts against the internal spring, and the other end is fixedly connected to a positioning block. The sleeve body provides a closed installation space for the internal spring and the telescopic column, preventing dust, oil, and other impurities in the industrial environment from entering the spring gap, ensuring that the spring maintains good elastic performance for a long time, and extending the service life of the buffer structure.

[0013] The present invention is further configured such that the inner wall of the positioning groove is provided with a flexible protective pad, the flexible protective pad is in contact with the inner wall of the positioning groove, the flexible protective pad fills the gap between the inner wall of the positioning groove and the cable sheath, avoids friction and wear caused by rigid contact between the cable and the positioning groove, has a certain elastic deformation capability, further enhances the clamping adaptability of the positioning groove, and improves the clamping stability.

[0014] The present invention is further configured such that a positioning post is fixedly connected to the bottom of the telescopic post, and one side of the positioning post extends into the inner cavity of the built-in spring. The positioning post plays a guiding role, restricts the movement trajectory of the telescopic post, and ensures that the telescopic post can only extend and retract along the axial direction of the sleeve body, avoiding spring jamming or positioning block displacement caused by the tilting of the telescopic post. The positioning post is inserted into the inner cavity of the built-in spring to prevent problems such as end detachment and deformation of the built-in spring during long-term repeated extension and retraction.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses the cooperation of connecting posts, threaded posts and fastening nuts to flexibly adjust the installation position of the connecting plate, thereby achieving spacing adjustment. It can flexibly adapt to the fixed space according to the diameter and quantity of cables. The elastic extension and contraction characteristics of the spring sleeve provide adaptive clamping force for the cable, which not only prevents the cable from loosening and shaking, but also avoids excessive compression. It effectively adapts to the mixed laying needs of cables of different specifications and improves the protection effect of the cable chain on the cable.

[0017] 2. This utility model uses threaded posts and fastening nuts for quick positioning and fixing, and can adjust the position of the cable fixing mechanism without disassembling the entire chain links. The cable fixing mechanism directly carries the cable through the positioning groove. The structure is intuitive and easy to operate. When it is necessary to repair or replace the cable, it is only necessary to adjust the adjustment mechanism or directly remove the cable without disassembling the main structure of the drag chain, which greatly reduces the maintenance difficulty and improves the operation efficiency.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-6This utility model is an industrial cable drag chain, including two section plates 1, which are symmetrically arranged. Both sides of the surface of the section plate 1 are provided with connection holes 5. A connecting block 2 is fixedly connected to one side of the section plate 1. An adjustment mechanism 3 is provided on one side of the connecting block 2. The adjustment mechanism 3 includes a connecting post 31. One side of the connecting post 31 is fixedly connected to the connecting block 2. Threaded posts 32 are fixedly connected to the top and bottom of the connecting post 31. A connecting plate 33 is sleeved on the surface of the threaded post 32. A fastening nut 34 is threadedly connected to the surface of the threaded post 32 and on one side of the connecting plate 33. Both sides of the connecting plate 33 are in contact with the section plate 1.

[0028] Specifically: Two threaded posts 32 are symmetrically distributed, providing bidirectional balanced support and positioning points for the connecting plate 33. The connecting plate 33 slides freely along the axial direction of the threaded posts 32 to adjust the installation position according to actual needs. The connecting plate 33 is locked and fixed in the preset position by the threaded engagement of the fastening nut 34 and the threaded post 32, preventing positional displacement due to vibration or other factors during use. Both sides of the connecting plate 33 are in contact with the section plate 1, forming a surface contact fit, which not only improves the stability of the connecting plate 33 after installation, but also limits the radial sway of the connecting plate 33 through the contact surface fit. The free sliding of the grooved column 32, combined with the locking function of the fastening nut 34, allows for flexible adjustment of the installation position of the connecting plate 33, adapting to the installation requirements of different cable specifications or the assembly scenarios of different equipment. It can achieve multi-scenario adaptation without replacing the entire component, improving the versatility of the cable chain. The two symmetrically arranged section plates 1 form a symmetrical clamping structure, providing balanced support and protection from both sides of the cable, avoiding cable chain deformation or cable offset caused by unilateral force, and improving the overall structural strength of the cable chain. The symmetrical design makes the cable chain more evenly stressed during bending and dragging, reducing local stress concentration and extending the fatigue life of the cable chain.

[0029] A cable fixing mechanism 4 is fixedly connected to one side of the connecting plate 33. The cable fixing mechanism 4 includes a fixing plate 41. One side of the fixing plate 41 is fixedly connected to the connecting plate 33. A spring sleeve 42 is fixedly connected to one side of the connecting plate 33. The spring sleeve 42 includes a sleeve body 421, an internal spring 422, and a telescopic column 423. A positioning column 6 is fixedly connected to the bottom of the telescopic column 423. One side of the positioning column 6 extends into the inner cavity of the internal spring 422. The sleeve body 421 is fixedly connected to the fixing plate 41. The internal spring 422 is located inside the sleeve body 421. One end of the telescopic column 423 abuts against the internal spring 422, and the other end is fixedly connected to the positioning block 43. A positioning block 43 is fixedly connected to one side of the spring sleeve 42. A positioning groove 44 is provided on the top of the positioning block 43. There are three positioning grooves 44, which are equidistant. A flexible protective pad is provided on the inner wall of the positioning groove 44. The flexible protective pad fits against the inner wall of the positioning groove 44.

[0030] Specifically: The position adjustment of the connecting plate 33 is synchronized with the cable laying requirements, avoiding messy cable distribution inside the cable chain. The elasticity of the spring sleeve 42 gives the positioning block 43 adaptive clamping capability, flexibly adjusting the clamping force according to the outer diameter of the cable, preventing cable loosening and displacement, and avoiding cable damage caused by excessive compression. The positioning groove 44 provides a space for the cable, realizing the orderly separation of single or multiple cables, reducing friction between cables, ensuring stable signal transmission and cable lifespan. The three positioning grooves 44 realize the independent placement of three cables, avoiding friction wear or signal interference caused by mixed contact of multiple cables, which is especially suitable for the classified laying of power cables and signal cables. The sleeve body 421 provides a closed installation for the built-in spring 422 and telescopic column 423. The space prevents dust, oil, and other impurities from entering the spring gap, ensuring the spring maintains good elasticity over a long period and extending the service life of the buffer structure. The flexible protective pad fills the gap between the inner wall of the positioning groove 44 and the cable sheath, preventing friction and wear caused by rigid contact between the cable and the positioning groove 44. It has a certain elastic deformation capability, further enhancing the clamping adaptability of the positioning groove 44 and improving clamping stability. The positioning post 6 acts as a guide, restricting the movement trajectory of the telescopic post 423 and ensuring that the telescopic post 423 can only extend and retract along the axial direction of the sleeve body 421. This prevents the spring from jamming or the positioning block 43 from shifting due to the tilting of the telescopic post 423. The positioning post 6 is inserted into the inner cavity of the built-in spring 422 to prevent the built-in spring 422 from falling off at the end or deforming during long-term repeated extension and retraction.

[0031] The working principle of this utility model is as follows: According to the specifications of the cable to be installed, the position of the cable fixing mechanism 4 is adjusted by the adjusting mechanism 3, the fastening nut 34 on the threaded column 32 is rotated, and the connecting plate 33 slides freely along the axial direction of the two symmetrically distributed threaded columns 32 until it moves to the preset position suitable for cable laying. Then the fastening nut 34 is tightened, and the connecting plate 33 is locked and fixed by the self-locking characteristic of the threaded engagement.

[0032] The cables are placed in the positioning slot 44, allowing the three cables to be placed independently. The built-in spring 422 applies a continuous and gentle elastic force to the positioning block 43 through the telescopic column 423, so that the positioning block 43 can flexibly adjust the clamping force according to the outer diameter of the cable. When the outer diameter of the cable is large, the telescopic column 423 compresses the built-in spring 422 to generate a greater clamping force. When the outer diameter of the cable is small, the built-in spring 422 rebounds to maintain stable clamping, which not only prevents the cable from loosening and shifting, but also avoids excessive squeezing and damage to the cable.

[0033] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
