Description

Technical Field

[0001] This utility model relates to the technical field of cable chain support components and equipment, and more specifically, to a cable chain anti-warping device. Background Technology

[0002] For bridge-type plastic cable carriers that support cables, they generally include an upper cover plate and a lower support plate, as well as separators and connecting sections between the upper cover plate and the lower support plate. In actual use, vertical installation is inevitable. Under these conditions, the cable carrier generally has a large stroke. In addition, due to its own weight and the bending of the internal cables, when the moving end of the cable carrier approaches the fixed end, the bending area below the cable carrier is very prone to warping. This causes the cable carrier to deviate from the preset movement track, resulting in significant wear and damage to the upper cover plate, lower support plate, and separators, thus affecting the service life of the cable carrier. Utility Model Content

[0003] The purpose of this utility model is to provide a cable chain anti-warping device. This cable chain anti-warping device, through the design of a flexible anti-warping sleeve and a concave anti-warping frame structure, can reduce the warping generated on the cable chain when the moving end approaches the fixed end, improve the stability, safety and reliability of the cable chain movement, and thus reduce the wear damage caused by cable chain warping to the upper cover plate, lower support plate and separator, and extend the overall service life of the cable chain.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cable chain anti-warping device includes a cable chain, which is divided into a moving end cable chain and a fixed end cable chain. The fixed end cable chain is fixed inside a mounting compartment with an opening at the bottom. The mounting compartment is fixed on a frame. A rectangular through groove is provided at the lower end of the outer side of the mounting compartment. Flexible anti-warping sleeves are provided between the rectangular through grooves. Triangular brackets are connected forward on both sides of the lower front side of the mounting compartment via screws. A concave anti-warping clip is connected between the three vertices of the triangular bracket. When the moving end cable chain approaches the fixed end cable chain, the three concave anti-warping clips are respectively located at the middle position of the inclined cable chain cover plate below the fixed end cable chain, the middle position of the horizontal cable chain cover plate at the junction of the moving end cable chain and the fixed end cable chain, and the middle position of the vertical cable chain cover plate at the bottom of the moving end cable chain.

[0006] As a further optimization of this solution, the inner side of the concave anti-bend card frame is provided with a concave adhesive buffer pad, and both sides of the concave anti-bend card frame are connected to the inner side of the three vertices of the triangular bracket by bolts.

[0007] As a further optimization of this solution, the flexible anti-warping sleeve is mounted on the mounting shaft, and both sides of the mounting shaft are connected to the slider through rotating bearing seats. Vertical blind grooves are provided on both sides of the rectangular through groove of the mounting chamber. A vertical guide rod is provided in the middle of the vertical blind groove. The slider is slidably mounted on the guide rod, and a buffer spring is mounted on the guide rod above the slider.

[0008] As a further optimization of this solution, the width of the rectangular through slot is greater than the width of the cable chain.

[0009] As a further optimization of this solution, the outer side of the buffer pad contacts the outer side of the connecting joints on both sides of the cable chain and the outer side of the upper cover plate. When the moving end cable chain is far away from the fixed end cable chain, the concave anti-bending frame is suspended in the air by the triangular bracket.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes a triangular support structure to install three concave anti-bend clips. When the moving-end cable chain approaches the fixed-end cable chain, the three concave anti-bend clips are positioned at the middle of the inclined cable chain cover plate below the fixed-end cable chain, the middle of the horizontal cable chain cover plate at the junction of the moving-end and fixed-end cable chains, and the middle of the vertical cable chain cover plate at the bottom of the moving-end cable chain. This reduces bending misalignment between adjacent cable chains in the lower bending area, achieving anti-bend operation below the cable chain and ensuring motion stability. Simultaneously, a flexible anti-tilting sleeve is designed to prevent tilting of the inclined cable chain below the fixed end, utilizing sliding... The structure, including blocks, buffer springs, and guide rods, provides a certain degree of upward freedom for the cable chain tilting below the fixed end. The elasticity of the buffer spring limits the upward position of the slider, thereby limiting the flexible anti-tilting sleeve and ultimately limiting the position of the cable chain tilting below the fixed end, resulting in a good anti-tilting effect. The flexible anti-tilting sleeve, combined with the buffer pad structure, provides the cable chain with a certain degree of freedom. Compared with rigid contact anti-tilting structures without any degree of freedom, it provides better protection for the cable chain components, reduces wear and tear on the upper cover plate, lower support plate, and separator caused by cable chain warping, and extends the overall service life of the cable chain.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0017] To address the existing problem that warping easily occurs in the bending area below the cable chain when the moving end approaches the fixed end, causing the cable chain to deviate from the preset movement track, resulting in significant wear and damage to the upper cover plate, lower support plate, and separator plates, and affecting the service life of the cable chain;

[0018] like Figure 1 As shown, this application includes a cable chain, which is divided into a moving end cable chain 1 and a fixed end cable chain 2. The fixed end cable chain 2 is fixed inside the mounting compartment 3 with an opening at the bottom. The mounting compartment 3 is fixed on the frame. A rectangular through groove is opened at the lower end of the outer side of the mounting compartment 3. A flexible anti-warping sleeve 6 is provided between the rectangular through grooves. The front sides of the lower side of the mounting compartment 3 are connected to triangular brackets 4 by screws 9. A concave anti-bend frame 5 is connected between the three vertices of the triangular bracket 4. When the moving end cable chain 1 approaches the fixed end cable chain 2, the three concave anti-bend frames 5 are respectively located at the middle position of the inclined cable chain cover plate below the fixed end cable chain 2, the middle position of the horizontal cable chain cover plate at the junction of the moving end cable chain 1 and the fixed end cable chain 2, and the middle position of the vertical cable chain cover plate at the bottom of the moving end cable chain 1.

[0019] like Figure 2 As shown, the inner side of the concave anti-bend frame 5 is provided with concave adhesive buffer pads 7, and both sides of the concave anti-bend frame 5 are connected to the inner side of the three vertices of the triangular bracket 4 by bolts 8.

[0020] like Figure 3 As shown, the flexible anti-warping sleeve 6 is mounted on the mounting shaft 10. Both sides of the mounting shaft 10 are connected to the slider through the rotating bearing seat 11. Vertical blind grooves 15 are provided on both sides of the rectangular through groove of the mounting box 3. A vertical guide rod 13 is provided in the middle of the vertical blind groove 15. The slider 12 is slidably mounted on the rod of the guide rod 13. A buffer spring 14 is mounted on the rod of the guide rod 13 above the slider 12.

[0021] Specifically, the width of the rectangular through slot is greater than the width of the cable chain, which facilitates the lifting of the inclined cable chain below the fixed end cable chain 2 to a certain height. When the moving end cable chain 1 moves away from the fixed end cable chain 2, the concave anti-bend bracket 5 is suspended by the triangular bracket 4. When the moving end cable chain 1 approaches the fixed end cable chain 2, the three concave anti-bend brackets 5 respectively block and limit the inclined cable chain below the fixed end cable chain 1, the horizontal cable chain at the junction of the moving end cable chain 1 and the fixed end cable chain 2, and the middle position of the vertical cable chain at the bottom of the moving end cable chain 1. The outer side of the buffer pad 7 contacts the outer side of the connecting joints on both sides of the cable chain and the outer side of the upper cover plate, reducing the bending misalignment between adjacent cable chains in the lower bending area, thus achieving the protection of the lower part of the cable chain. The flexible anti-warping sleeve 6 prevents the cable chain from warping below the fixed end 2. The flexible anti-warping sleeve 6 blocks the cable chain and moves upward a certain distance to compress the return spring 14. Then, under the elastic force of the return spring 14, the flexible anti-warping sleeve 6 returns to its original position, effectively limiting the position of the cable chain below the fixed end 2. The anti-warping effect is good. The flexible anti-warping sleeve 6, combined with the buffer pad 7 structure, provides the cable chain with a certain degree of freedom. Compared with a rigid contact anti-warping structure without freedom, it provides better protection for the cable chain components, reducing wear damage to the upper cover plate, lower support plate, and separator caused by cable chain warping, and extending the overall service life of the cable chain.
