Description

Technical Field

[0001] This utility model relates to the field of overhead cable support technology, specifically a long-distance overhead cable support module. Background Technology

[0002] In fields such as industrial automation and mechanical equipment, cable chains are widely used in machine tools, robots, lifting and transportation equipment as key components used to protect cables, oil pipes and other pipelines and guide their movement with equipment.

[0003] When cable carriers need to operate over long distances, their overhead support capacity is significantly insufficient due to limitations in structural strength and material properties. Once the travel distance reaches a certain length, the middle section of the cable carrier is prone to "collapse" due to gravity, leading to uneven stress on the pipeline, increased friction between the cable carrier and surrounding structures, and even malfunctions such as jamming and breakage, severely impacting the normal operation and service life of the equipment. To address this, we propose a long-distance cable carrier overhead support module. Utility Model Content

[0004] The purpose of this utility model is to provide a long-distance cable chain overhead support module to solve the problem mentioned in the background art that when the cable chain needs to achieve long-distance operation, its overhead capacity is significantly insufficient due to the limitations of its own structural strength and material properties. When the stroke reaches a certain length, the middle section of the cable chain is prone to "collapse" due to gravity, resulting in uneven stress on the pipeline, increased friction between the cable chain and the surrounding structure, and even causing malfunctions such as jamming and breakage, which seriously affects the normal operation and service life of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a long-distance cable chain overhead support module, comprising: a cable chain body, and an extension bracket, a support body fixedly connected to the extension bracket, a cover plate fixedly connected to the outside of the support body, a swing bracket provided inside the support body, the swing bracket supporting the cable chain body, and a reset component provided on the swing bracket, the reset component resetting the swing bracket.

[0006] The swing bracket and the support body are provided with mounting holes on both sides. Screws are installed in the mounting holes. The screws connect the swing bracket and the support body. A nut is provided at the end of the screw away from the support body. The screw is rotatably connected to the swing bracket and the support body, so that the swing bracket can swing relative to the support body around the screw axis.

[0007] The reset assembly includes a cylindrical spring fixedly connected to the swing bracket, with the other end of the cylindrical spring fixedly connected to the inner wall of the cover plate; it also includes: The coil spring is located between the support body and the swing bracket. One end of the coil spring is fixedly connected to the swing bracket, and the other end of the coil spring is fixedly connected to the inner wall of the support body.

[0008] The swing bracket is equipped with a mounting groove, and a roller is installed in the mounting groove. The roller extends out of the swing bracket toward a part of the cable chain body.

[0009] The roller has a roller cover on its outer side, and fastening bolts are provided on the roller cover. The roller cover is connected to the swing bracket through the fastening bolts to fix the roller axially in the mounting groove.

[0010] The swing bracket and reset assembly are symmetrically arranged on both sides of the cable chain along the width direction, and multiple sets can be arranged along the length direction of the cable chain.

[0011] A washer is provided between the nut and the swing bracket.

[0012] This utility model has at least the following beneficial effects: In use, this utility model effectively prevents the cable chain from "collapsed" by having the top of the swing bracket contact the bottom of the cable chain. The rolling friction generated by the rollers on the swing bracket also reduces wear and extends service life. Through the cooperation of the cylindrical spring and coil spring in the reset component, the swing bracket can be quickly reset after the cable chain passes, ensuring continuous and stable support without manual intervention, thus improving convenience and reliability. The two work together to significantly improve the durability of the cable chain, making it perform excellently in long-distance cable chain support. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: a long-distance cable chain overhead support module, comprising: a cable chain body 1, and an extension bracket 2. A support body 3 is fixedly connected to the extension bracket 2, and a cover plate 4 is fixedly connected to the outside of the support body 3. A swing bracket 5 is provided inside the support body 3, supporting the cable chain body 1. A reset component 6 is provided on the swing bracket 5, resetting the swing bracket 5. The extension bracket 2 can be adjusted according to its height to adapt to different models and bending radii of the cable chain body 1, ensuring precise and stable support for the cable chain body 1. The top of the extension bracket 2 is fixedly connected to the support body 3 by fastening bolts 13, etc., and the connection part is reinforced to have sufficient load-bearing strength. The top of the swing bracket 5 contacts the bottom of the cable chain body 1, effectively supporting the cable chain body 1 and preventing the cable chain body 1 from "collapsed" due to its own weight during long-distance operation. After the cable chain body 1 passes, the reset component 6 quickly moves the swing bracket 5 back to its initial support position to ensure continuous support for subsequent sections of the cable chain body 1.

[0017] The swing bracket 5 and the support body 3 are provided with mounting holes 7 on both sides. Screws 8 are provided in the mounting holes 7. The screws 8 connect the swing bracket 5 and the support body 3. A nut 9 is provided at the end of the screw 8 away from the support body 3. The screw 8 is rotatably connected to the swing bracket 5 and the support body 3, so that the swing bracket 5 can swing relative to the support body 3 around the axis of the screw 8. The screw 8 is in a rotational clearance fit with the swing bracket 5 and the support body 3, so that the swing bracket 5 can swing flexibly relative to the support body 3 around the axis of the screw 8 to accommodate the passage of the cable chain body 1.

[0018] The reset assembly 6 includes a cylindrical spring 61 fixedly connected to the swing bracket 5, with the other end of the cylindrical spring 61 fixedly connected to the inner wall of the cover plate 4; it also includes a coil spring 62, located between the support body 3 and the swing bracket 5. One end of the coil spring 62 is fixedly connected to the swing bracket 5, and the other end is fixedly connected to the inner wall of the support body 3. The cylindrical spring 61 is in a pre-compressed state, providing continuous reset force to the swing bracket 5. The coil spring 62 is available in left-hand and right-hand versions, respectively installed on the left and right sides of the swing bracket 5. The two types cooperate to provide the main power source for the reset of the swing bracket 5, ensuring that the swing bracket 5 can quickly and accurately return to its original position after the cable chain body 1 passes.

[0019] The swing bracket 5 is provided with a mounting groove 10, and a roller 11 is provided in the mounting groove 10. The roller 11 extends out of the swing bracket 5 towards a part of the cable chain body 1. The shape of the mounting groove 10 matches the shape of the roller 11. When the cable chain body 1 moves to this position, the roller 11 contacts the bottom surface of the cable chain body 1, changing the sliding friction into rolling friction, which greatly reduces the wear between the two.

[0020] A roller cover 12 is provided on the outer side of the roller 11. The roller cover 12 is provided with fastening bolts 13. The roller cover 12 is connected to the swing bracket 5 through the fastening bolts 13 to fix the roller 11 axially in the mounting groove 10. The fastening bolts 13 pass through the threaded holes and are screwed into the corresponding threaded holes on the swing bracket 5, thereby fixing the roller 11 axially in the roller mounting groove 10. This effectively prevents the roller 11 from axially moving or falling off during rotation and ensures the stability of the roller 11 during operation.

[0021] The swing bracket 5 and the reset assembly 6 are symmetrically arranged on both sides of the cable chain body 1 along the width direction, and multiple sets can be arranged along the length direction of the cable chain body 1. This can effectively form a balanced support force on the cable chain body 1 from both sides, improving the stability of the cable chain body 1 during operation. Moreover, multiple sets work together to achieve long-distance overhead support for the cable chain body 1, further enhancing the support effect.

[0022] When using the overhead support module for the long-distance cable chain body 1, the extension bracket 2 is used to adapt to cable chain bodies 1 of different heights. Then, multiple sets of swing brackets 5 and reset components 6 are arranged along the length of the cable chain body 1 as needed. When the cable chain body 1 reaches the swing bracket 5, the bottom of the cable chain body 1 contacts the roller 11 on the swing bracket 5. The roller 11 rotates, converting sliding friction into rolling friction. Simultaneously, the pressure on both sides of the cable chain body 1 causes the swing bracket 5 to swing inwards around the axis of the screw 8 towards the support body 3. During this process, the cylindrical spring 61 is compressed and the coil spring 62 is twisted, storing elastic force. After the cable chain body 1 passes, the pressure disappears, and the coil spring 62 and cylindrical spring 61 of the reset component 6 release their elastic force. Under the reaction force of the coil spring 62 and cylindrical spring 61, the swing bracket 5 swings back to its initial position, continuing to support the subsequent sections of the cable chain body 1, ensuring that the cable chain body 1 does not "collapse" during long-distance operation and that its operation is smooth and stable.

[0023] Example 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a washer 14 is provided between the nut 9 and the swing bracket 5. The washer 14 can increase the contact area between the nut 9 and the swing bracket 5, disperse the pressure, prevent the nut 9 from loosening due to vibration during equipment operation, and reduce the direct friction between the swing bracket 5 and the nut 9 when swinging, thus extending the service life of the components.
