Description

Technical Field

[0001] This invention relates to the field of cable chain equipment technology, specifically to a cable chain structure for storing cables. Background Technology

[0002] Cable chains, also known as tank chains, are suitable for use in complex motion applications. They can store, pull, and protect internal cables, oil pipes, air pipes, water pipes, etc. Each section of the cable chain can be opened for easy installation and maintenance. They operate with low noise, are wear-resistant, and can move at high speeds. Currently, the main body of cable chains on the market is composed of multiple cable chain blocks that are hinged together. Cable chains are generally placed horizontally. When the traction end moves left and right, the cable chain will form a curved section at the connection between the upper and lower halves. During the lateral movement of the main body of the cable chain, the bending position is constantly changing. The cable harness has the greatest deformation and the greatest tensile force in the curved section. During long-term operation and repeated lateral movement, the cable chain is also repeatedly bent and displaced. The entire cable harness will be subject to long-term wear due to the bending caused by the lateral movement of the cable chain, which can easily lead to problems such as cracking, aging, or even breakage of the cable harness skin.

[0003] Currently, the only solution to this problem is to increase the curvature of the overall bending section of the cable chain, that is, to increase the distance between the upper and lower halves, thereby increasing the length of the bending section and the bending angle, thus improving the bending deformation problem. However, this will increase the overall space occupied by the cable chain and the corresponding operating space, and will also require a longer overall length of the cable chain, and the internal wiring harness will also need to be increased accordingly. However, even with the cable chain setup that sacrifices cost and space, the maximum change in the bending profile of the wiring harness still cannot exceed the maximum outer contour range of the cable chain itself. How to maximize the overcoming of bending deformation problem of the wiring harness while shortening the size of the wiring harness and the overall cable chain has become a contradictory issue.

[0004] Therefore, to address the above issues, we need a cable chain device that can both retain the traditional cable chain size and installation space while reducing the wear and tear caused by repeated bending of the internal wiring harness. Summary of the Invention

[0012] As a further embodiment of the present invention, a wire release box for winding the wire harness is fixedly installed on the traction side of the drag chain body, and the wire release box elastically winds up the excess wire harness for the lateral movement mechanism to pull out.

[0013] As a further embodiment of the present invention, the belt drive mechanism includes a belt, a reversing pulley, and a main lead screw gear.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention modifies the structure of a single cable chain block in a conventional cable chain body. It uses the change in the relative angle of the cable chain block as it moves from the lower half to the upper half as the driving force for adjustment. This allows the bending angle of the original wire harness at the bending section of the changing position to be increased and adjusted in real time. This prevents the wire harness in the bending section of the cable chain body from being subjected to excessive bending deformation force during operation, which could easily lead to damage. No external adjustment control unit or wireless external drive device is required. The function of automatic angle adjustment and wire harness protection of the internal wire harness of the cable chain body can be achieved by simply modifying the original structure of the cable chain body itself.

[0018] 2. When the wire clamp of the present invention extends outward, the wire clamp will also generate a lateral displacement to counteract the lateral pulling on the wire bundle due to the change in the straight distance between adjacent wire clamps.

[0019] 3. The wire harness cleaning plate provided in this invention can perform a large displacement cleaning action along the wire harness when the main slider drives the wire clamp to extend outward with a small displacement;

[0020] 4. The cleaning brush provided in this invention can automatically clean the cable chain cross plates inside the cable chain block where dust easily accumulates. Attached Figure Description

Detailed Implementation

[0031] Please see Figures 1-8 The present invention provides a technical solution: a cable carrier device for storing cables, comprising multiple cable carrier blocks 1 that are hinged to each other, the multiple cable carrier blocks 1 being hinged to each other to form a cable carrier body, and each cable carrier block 1 having a cable clamp 2 for storing cables inside.

[0032] The cable chain block 1 includes two vertically arranged cable chain vertical plates 10, which are fixedly connected to each other by a horizontally arranged cable chain horizontal plate 11, and two adjacent cable chain blocks 1 are hinged by a rotating cable chain shaft 12.

[0033] The wire clamp 2 is installed on the side wall of the drag chain vertical plate 10 via a screw lifting mechanism. A shaft bevel gear 13 is fixedly installed on the shaft wall of the drag chain shaft 12. A shaft plate 16 is fixedly installed on the side wall of the drag chain vertical plate 10. A reversing shaft 15 is rotatably installed on the inner side plate of the shaft plate 16. A reversing bevel gear 14 for meshing with the shaft bevel gear 13 is fixedly installed on the outer end of the reversing shaft 15. The reversing shaft 15 is connected to the power input end of the screw lifting mechanism via a belt drive mechanism.

[0034] When the relative angle between two adjacent drag chain blocks 1 changes, the drag chain shaft 12 rotates, the belt drive mechanism drives the screw lifting mechanism to move, and the screw lifting mechanism drives the wire clamp 2 to extend towards the outer ring of the drag chain body.

[0035] At work, such as Figure 1 As shown, multiple cable chain blocks 1 are hinged together to form a cable chain body. The cable harness is clamped and installed inside the cable chain body by multiple cable clamps 2. As shown in the figure, the traction end of the cable chain body is located on the right side. The overall movement mode of the cable chain body is left and right movement. A bending section appears on the left side of the cable chain body. At this time, the cable harness receives the greatest deformation tension. During the long-term left and right movement of the cable chain body, the cable harness in the bending section is prone to damage over time. Therefore, the present invention improves the cable clamps 2:

[0036] The relative angle between adjacent cable chain blocks 1 at the bending section changes. From the perspective of a single cable chain block 1, each block rotates approximately 180 degrees from the lower half to the upper half of the cable chain body. The pivot point of this rotation is the hinge between two adjacent cable chain blocks 1. In this invention, the conventional hinge is replaced by a rotatable cable chain shaft 12. This shaft 12 is rotatably mounted between two cable chain vertical plates 10 and can rotate. One side of the vertical plate 10 is fixed to the shaft wall of the shaft 12. When the two cable chain blocks 1 rotate relative to each other, the shaft 12 rotates. The rotation of the shaft 12 is mediated by a shaft bevel gear 13 and a reversing bevel gear. The reversing gear 14 drives the reversing shaft 15 to rotate. The reversing shaft 15 drives the screw lifting mechanism through the belt drive mechanism. The screw lifting mechanism moves the wire clamp 2. It should be noted that when the drag chain block 1 in the lower half of the drag chain body moves from the curved section to the upper half, the rotation direction of adjacent drag chain blocks 1 is the same. That is, the 180-degree rotation of the drag chain block 1 from the lower half to the upper half is unidirectional and continuous. Therefore, the direction in which the lifting screw mechanism drives the wire clamp 2 to move is also unidirectional, that is, towards the outer ring of the drag chain body. So when the drag chain block 1 moves from the curved section to the upper half of the drag chain body, the wire clamp 2 inside will move as follows: Figure 1 As shown, the original bending angle of the wire harness will be changed by the action of multiple wire clamps 2 extending outward from the upper part of the drag chain body. The original side U-shape will be changed to an upward-angled shape in the upper part, which will expand the original bending angle. As a result, the deformation and tensile force on the wire harness in the bending section will be greatly reduced.

[0037] It should be noted that in this invention, a single drag chain block 1 is formed by connecting and fixing two drag chain vertical plates 10 to a single drag chain horizontal plate 11. When the drag chain block 1 is in the lower half of the drag chain body, the drag chain horizontal plate 11 is at the top, covering the wire harness below. The wire clamp 2 is housed inside the drag chain block 1. When the drag chain block 1 moves to the upper half of the drag chain body, the drag chain horizontal plate 11 rotates and moves downward, and the wire clamp 2 extends upward. When adjacent drag chain blocks 1 become flat, the drag chain shaft 12 does not rotate relative to each other. The state no longer changes. During the process of the drag chain block 1 moving from the upper half to the lower half, the drag chain shaft 12 rotates in the opposite direction, and the wire clamp 2 will return to the initial state of storage. It will not affect the normal movement of the drag chain body. When the drag chain block 1 moves towards the upper half, the wire clamp 2 inside the drag chain block 1 will move outward. The wire clamp 2 can be set to move only inside the drag chain block 1, or the wire clamp 2 can be set to extend completely out of the outer contour range of the drag chain block 1, thereby further expanding the angle of the maximum wiring curvature of the outer contour of the drag chain body itself.

[0038] Therefore, by changing the structure of a single cable block 1 in a conventional cable chain body, and using the change in the relative angle of the cable block 1 as it moves from the lower half to the upper half as the adjustment driving amount, the bending angle of the original wire harness at the bending section at the changing position can be increased and adjusted in real time. This prevents the wire harness in the bending section from being subjected to excessive bending deformation force during operation of the cable chain body, which could easily lead to damage. No external adjustment control unit or wireless external drive device is required. The function of automatic angle adjustment and wire harness protection of the internal wire harness of the cable chain body can be achieved by simply modifying the original structure of the cable chain body itself.

[0039] As a further embodiment of the present invention, the screw lifting mechanism includes a main slider 3, a main screw 30, and a main guide rod 31. The main screw 30 is rotatably mounted on the drag chain vertical plate 10 along the moving direction of the wire clamping frame 2. The main slider 3 is threaded onto the main screw 30. The main guide rods 31 are fixed parallel to each other on both sides of the main screw 30. The two sides of the main slider 3 are slidably mounted on the rod wall of the corresponding side of the main guide rod 31. The wire clamping frame 2 is mounted on the main slider 3.

[0040] During operation, the drag chain shaft 12 drives the reversing shaft 15 to rotate through the shaft bevel gear 13 and the reversing bevel gear 14. The reversing shaft 15 drives the main lead screw 30 to rotate through the belt drive mechanism. Under the restriction of the main lead screws 31 on both sides, the main slider 3 will perform translational sliding action on the main lead screw 30, so that the wire clamp 2 installed on the main slider 3 can perform translational lifting and lowering operation.

[0041] As a further embodiment of the present invention, the wire clamp 2 is installed on the main slider 3 via a transverse mechanism. The transverse mechanism includes a wire clamp connecting plate 21. The wire clamp connecting plate 21 is fixedly installed on the main slider 3. A wire clamp screw 22 is rotatably installed on the wire clamp connecting plate 21. A 20 is threaded onto the wire clamp screw 22. Wire clamp guide rods 24 are fixed on both sides of the wire clamp screw 22. The two sides of the 20 are slidably sleeved on the corresponding side of the wire clamp guide rod 24. The wire clamp 2 is fixedly installed on the 20. A wire clamp follower gear 23 is fixed on the end of the wire clamp screw 22 facing the main slider 3. A wire clamp linkage gear 25 for meshing with the wire clamp follower gear 23 is rotatably installed on the wire clamp connecting plate 21 via a linkage gear mounting plate 26. A wire clamp rack 27 for meshing with the wire clamp linkage gear 25 is fixedly installed on the drag chain vertical plate 10. The wire clamp rack 27 is arranged parallel to the direction of the main screw 30.

[0042] During operation, as the wire clamp 2 moves towards the outer ring of the drag chain body, and the spacing between adjacent wire clamps 2 is fixed, when the outward extension heights of adjacent wire clamps 2 are inconsistent, a lateral pulling force will be generated on the wire harness between the two wire clamps 2. In order to counteract this lateral pulling caused by the outward extension of the wire clamp 2, the entire wire clamp 2 is mounted on the main slider 3 through a lateral movement mechanism. When the main slider 3 drives the wire clamp 2 to move outward, the wire clamp connecting plate 21 moves together with the main slider 3. During the movement, the wire clamp linkage gear 25 meshes with the wire clamp rack 27 to generate rotation. The wire clamp linkage gear 25 drives the wire clamp follower gear 23 to rotate, thereby causing the wire clamp screw 22 to rotate. Under the limiting guidance of the wire clamp guide rod 24, the wire clamp 2 moves laterally along the wire clamp screw 22. Thus, when the wire clamp 2 extends outward, the wire clamp 2 will also generate a lateral displacement to counteract the lateral pulling on the wire harness caused by the change in the straight-line distance between adjacent wire clamps 2.

[0043] As a further embodiment of the present invention, a wire release box 6 for winding the wire harness is fixedly installed on the traction side of the drag chain body, and the wire release box 6 elastically winds up the excess wire harness for the lateral movement mechanism to pull out.

[0044] During operation, when the lateral movement mechanism moves laterally, the wire release box 6 can pre-wrap up the excess wire length inside it. When the lateral movement mechanism moves laterally, the excess wire can be pulled out, thus facilitating the lateral movement of the wire to counteract the lateral pulling force and further protect the wire.

[0045] As a further embodiment of the present invention, the belt drive mechanism includes a belt 18, a reversing pulley 17 and a main lead screw gear 32. The main lead screw gear 32 is fixed to the top outer end of the main lead screw 30. The main pulley 33 and the reversing pulley 17 are respectively fixedly installed on the outer end face of the main lead screw gear 32 and the shaft wall of the reversing shaft 15. The main pulley 33 and the reversing pulley 17 are connected by the belt 18.

[0046] During operation, when the drag chain shaft 12 drives the reversing shaft 15 to rotate through the shaft bevel gear 13 and the reversing bevel gear 14, the reversing shaft 15 drives the reversing pulley 17 to rotate synchronously. The reversing pulley 17 drives the main pulley 33 to rotate through the belt 18. The main pulley 33 and the main lead screw gear 32 will drive the main lead screw 30 to rotate, thereby the lead screw lifting mechanism will drive the wire clamp 2 to extend outward.

[0047] As a further embodiment of the present invention, the inside of the drag chain block 1 is provided with a wire harness cleaning plate 4 for cleaning dust on the surface of the wire harness. Multiple wire harness cleaning brushes 40 are fixedly installed on the panel of the wire harness cleaning plate 4. A cleaning connecting plate 41 is fixed on one side of the main slider 3. A cleaning screw 43 parallel to the extension direction of the wire harness is rotatably installed on the cleaning connecting plate 41. A cleaning slider 42 is threaded onto the cleaning screw 43. The wire harness cleaning plate 4 is fixedly installed on the cleaning slider 42. A cleaning follower gear 44 is fixed at the outer end of the cleaning screw 43 facing the main slider 3. A cleaning linkage gear 45 that meshes with the cleaning follower gear 44 is rotatably installed on the cleaning connecting plate 41 through the cleaning gear mounting plate 46. A cleaning rack 47 parallel to the direction of the main screw 30 is fixed on the drag chain vertical plate 10. The cleaning linkage gear 45 meshes with the cleaning rack 47.

[0048] During operation, when the main slider 3 drives the cleaning connecting plate 41 to slide and translate, the cleaning linkage gear 45 and the cleaning rack 47 generate relative displacement. The cleaning linkage gear 45 drives the cleaning follower gear 44 to rotate together, and the cleaning follower gear 44 drives the cleaning screw 43 to rotate. The cleaning screw 43 drives the limited cleaning slider 42 to move laterally along the direction of the cleaning screw 43. Thus, the wire harness cleaning plate 4 will perform a cleaning action on the surface of the wire harness along the direction of the wire harness extension. It should be noted that the cleaning linkage gear 45 and the cleaning follower gear 44 are mainly used for speed change. Because the displacement of the main slider 3 driving the wire clamp 2 is small, while the cleaning lateral movement of the wire harness cleaning plate 4 should be as large as possible, the angular displacement of the cleaning follower gear 44 needs to be as large as possible. Therefore, the speed can be adjusted by the meshing relationship of the cleaning rack 47, the wire clamp linkage gear 25 and the cleaning follower gear 44, so that when the main slider 3 drives the wire clamp 2 to produce a small outward displacement, the wire harness cleaning plate 4 can produce a large displacement cleaning action along the wire harness.

[0049] As a further embodiment of the present invention, a cable chain cleaning frame 5 for dust removal is provided on one side of the cable chain cross plate 11. A cable chain screw 52 is rotatably mounted on the cable chain cross plate 11. A cable chain cleaning slider 51 is threaded onto the cable chain screw 52. Cable chain guide rods 53 are fixed on both sides of the cable chain screw 52. The two sides of the cable chain cleaning slider 51 are slidably sleeved on the corresponding side of the cable chain guide rod 53. The cable chain cleaning frame 5 is fixedly installed on both sides of the cable chain cleaning slider 51. Multiple cable chain cleaning brushes 50 are fixedly installed on the panel of the cable chain cleaning frame 5 facing the cable chain cross plate 11. The cable chain screw 52 and the main screw 30 are connected by two cleaning bevel gears 54 that mesh perpendicularly with each other.

[0050] During operation, when the main lead screw 30 rotates, it drives the support screw 52 to rotate via two cleaning bevel gears 54. When the support screw 52 rotates, it drives the support cleaning slider 51 to move along the extension direction of the drag chain cross plate 11, thereby cleaning the surface of the drag chain cross plate 11. Here, the radius of the cleaning bevel gear 54 on one side of the main lead screw 30 can be set much larger than that on the side of the support screw 52, ​​thereby increasing the angular displacement of the support screw 52 and achieving a large displacement of the support cleaning brush 50.
