Description

Technical Field

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

[0002] Plastic cable chains are mainly used for pulling and protecting cables and other wire harnesses. For cable chains longer than two meters, they need to perform frequent reciprocating motion during operation. When they move to one side and approach the maximum stroke position, due to their long length and the weight of the internal cables, the middle of the plastic cable chain will sag. Furthermore, the sag links change continuously during the movement, which can easily cause wear and breakage of the cable chain links.

[0003] Currently, for longer plastic cable chains, multiple rollers supported by brackets are generally used to support the drooping area of ​​the plastic cable chain. This drooping support structure has the following problems: First, when the closed end of the cable chain moves to the support area, the drooping support structure needs to be frequently removed so that the cable chain can continue to run, which is time-consuming and labor-intensive; Second, the existing drooping support structure is supported by a single roller, which does not provide sufficient support for the drooping area and cannot flexibly adjust the support point according to the different weights of plastic cable chains. Utility Model Content

[0004] The purpose of this utility model is to provide a drooping support device for plastic cable chains. This drooping support device adopts a rotating structure, which makes it easy to move out in time when the closed end of the cable chain moves to the support area without affecting the normal operation of the cable chain. At the same time, the support structure has three adjustable support points to adapt to the support needs of plastic cable chains of different weights, and the support effect is better.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A plastic cable carrier droop support device includes a plastic cable carrier composed of several interconnected cable carrier units. Cables pass through the inside of the plastic cable carrier, which is embedded in a track. Slide grooves are provided on both sides of the track, and a base trolley is slidably installed inside each slide groove. Several threaded plates for connecting equipment are provided on the upper surface of the base trolley. Several droop support devices are spaced apart along the direction of the plastic cable carrier on one side of the slide groove. Each droop support device includes a base. A lifting plate is connected upwards to both sides of the upper surface of the base via telescopic supports. A rotating bearing seat is installed at the center of the upper surface of the lifting plate. The rotating part above the rotating bearing seat is connected upwards to the output shaft of a drive motor. The drive motor is mounted above the lifting plate via an L-shaped connecting plate. A controller is installed on the upper surface of the L-shaped connecting plate and is connected to the drive motor via wiring.

[0007] As a further optimization of this solution, a connecting rod is connected to the outer side of the upper rotating part of the rotating bearing seat. A rotating shaft is connected to the outer end of the connecting rod. A support roller is mounted on the shaft. Symmetrical L-shaped telescopic connecting rods are provided at intervals on the connecting rod. The telescopic section of the L-shaped telescopic connecting rod is forward-facing and the outer end of the telescopic section is connected to the rotating shaft. A support roller is mounted on the shaft. All the support rollers extend at intervals into the area below the drooping area of ​​the plastic cable chain.

[0008] As a further optimization of this solution, the L-shaped telescopic connecting rod and the telescopic support are both limited by the locking bolts of the non-telescopic section.

[0009] As a further optimization of this solution, the controller is connected to an external control box via a wireless signal. The control box controls the forward and reverse rotation of the drive motor, thereby controlling the rotation of the support roller.

[0010] As a further optimization of this solution, the support roller, after turning outward, does not come into contact with the plastic cable chain and the base trolley.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] In this utility model, a drive motor is set to drive the connecting rod to rotate, thereby driving the support roller to turn outward or inward. When the closed end of the cable chain moves to a certain drooping support device area, the support roller can be turned outward without affecting the normal operation of the cable chain. When a certain section of plastic cable chain needs to be supported, the support roller is turned inward to a position below the drooping area of ​​the plastic cable chain for support.

[0013] This invention utilizes a symmetrical L-shaped telescopic linkage structure to extend the support rollers on both sides, forming a wider support surface with the central support roller. This surface jointly supports the drooping plastic cable chain in this area. The support structure has three adjustable support points to accommodate the support needs of plastic cable chains of different weights, resulting in a better support effect.

Detailed Implementation

[0018] 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.

[0019] To address the issues that require frequent removal of the droop support structure to allow the cable chain to continue operating when the closed end of the cable chain moves to the support area, which is time-consuming and labor-intensive, and that the existing droop support structure is a single roller support, which does not provide sufficient support for the droop area and cannot flexibly adjust the support point according to different weights of plastic cable chains;

[0020] like Figure 1 As shown, this application includes a plastic cable chain 1 composed of several cable chain units connected to each other. A cable 18 passes through the inside of the plastic cable chain 1. The plastic cable chain 1 is embedded in the inside of the track 2. Slide grooves 3 are provided on both sides of the track 2. A base trolley 4 is slidably installed inside the slide groove 3. Several threaded plates 5 for connecting equipment are provided on the upper surface of the base trolley 4. Several drooping support devices are provided at intervals along the direction of the plastic cable chain 1 on the outside of one side of the slide groove 3.

[0021] like Figure 2 As shown, each of the drooping support devices includes a base 6. Both sides of the upper surface of the base 6 are connected to a lifting plate 8 via telescopic support columns 7. A rotating bearing seat 10 is installed at the center of the upper surface of the lifting plate 8. The rotating part above the rotating bearing seat 10 is connected to the output shaft of the drive motor 16. The drive motor 16 is mounted above the lifting plate 8 via an L-shaped connecting plate 15. A controller 17 is installed on the upper surface of the L-shaped connecting plate 15. The controller 17 is connected to the drive motor 16 via a line.

[0022] A connecting rod 11 is connected to the outer side of the rotating part above the rotating bearing seat 10. A rotating shaft 14 is connected to the outer end of the connecting rod 11. A support roller 13 is mounted on the shaft of the rotating shaft 14. Symmetrical L-shaped telescopic connecting rods 12 are provided at intervals on the rod of the connecting rod 11. The telescopic section of the L-shaped telescopic connecting rod 12 is forward-facing and the outer end of the telescopic section is connected to the rotating shaft 14. A support roller 13 is mounted on the shaft of the rotating shaft 14. All the support rollers 13 extend at intervals into the position below the drooping area of ​​the plastic drag chain 1. The L-shaped telescopic connecting rod 12 and the telescopic support column 7 are both limited by the locking bolts 9 of the non-telescopic section.

[0023] Specifically, the controller 17 is connected to an external control box via a wireless signal. The control box controls the forward and reverse rotation of the drive motor 16, thereby controlling the rotation of the support roller 13. After the support roller 13 rotates outward, it does not contact the plastic cable chain 1 and the base trolley 4. In use, the height of the lifting plate 8 can be adjusted by the telescopic support column 7 according to the height of the plastic cable chain 1 being used, so that the support roller 13 can be extended into the lower area of ​​the plastic cable chain 1 at intervals. Then, according to the weight of the plastic cable chain 1 and the weight of the cable 18, the distance between the two side support rollers 13 and the middle support roller 13 can be adjusted by the L-shaped telescopic connecting rod 12. Through three adjustable support points, the support needs of plastic cable chains 1 of different weights can be adapted, forming a wider support surface to jointly support the plastic cable chain 1 hanging in this area, resulting in a better support effect.

[0024] When the closed end of the plastic cable chain 1 moves to a certain area of ​​the drooping support device, it can turn outward to support the roller 13 without affecting the normal operation of the plastic cable chain 1. When it is necessary to support a certain section of the plastic cable chain 1, it can turn inward to support the roller 13 to a position below the drooping area of ​​the plastic cable chain 1 for support. Compared with traditional support devices, it does not require reciprocating disassembly and only needs to be remotely controlled through the control box.
