Description

Technical Field

[0001] This utility model relates to the field of signal cable laying technology, and in particular to a device for storing spare signal cables in a cable trough. Background Technology

[0002] A signal cable is a signal transmission tool. To avoid signal interference, a shielding layer is placed on the outside of the signal cable. The shielding layer that wraps the conductor is usually made of conductive cloth, woven copper mesh, or copper foil (aluminum). The shielding layer needs to be grounded so that external interference signals can be conducted to the ground, preventing interference signals from entering the inner conductor and reducing signal loss. During the installation of a signal cable, a section is usually reserved for line maintenance and to offset temperature stress.

[0003] To save space for reserved signal cables, they are coiled into an S-bend and laid within the cable tray. Common signal cable coiling devices typically rely on conductor rollers to feed the signal cables, and then use a cable clip at one end of a push rod to bend the cable into an S-bend. However, in practice, the cable clip at the push rod end is usually made of a rigid material, which can scratch the outer wall of the signal cable and damage it. On the other hand, some cable clips made of soft materials are prone to excessive deformation and breakage during the push rod's pressure, affecting the bending operation of the signal cable. Therefore, we propose a signal cable coiling device for use within the cable tray. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for storing spare signal cables in cable troughs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for storing spare signal cables in a cable trough, comprising a first substrate and a second substrate. The first substrate is movably connected to one end of the second substrate via a threaded screw and a guide rod. Shaping mechanisms are alternately installed on both sides of the first and second substrates, and the shaping mechanisms are used to bend and shape the signal cables. A conveying mechanism is provided on the outer wall of the first substrate, and the conveying mechanism is used to position and convey the signal cables. A supporting mechanism is provided on the outer wall of the second substrate, and the supporting mechanism is used to limit and drag the signal cables. Displacement mechanisms are provided on the inner walls of both the first and second substrates, and the displacement mechanisms are used to move the first and second substrates.

[0006] Optionally, the shaping mechanism includes mounting frames respectively installed on both sides of the first substrate and the second substrate. An electric push rod is fixedly connected to the outer wall of the mounting frame. An extension frame is fixedly connected to the telescopic end of the electric push rod. A positioning slot is opened at one end of the extension frame. A bending push block is inserted and installed inside the positioning slot. A side guard is fixedly connected to one side of the bending push block. A mounting screw hole is opened through the extension frame. A positioning bolt is rotatably installed inside the side guard. One end of the positioning bolt passes through the mounting screw hole.

[0007] Preferably, the side guard is made of hard plastic, the bending push block is made of soft rubber, the side guard and the bending push block are an integral structure, and the side guard covers the outer wall of the extension frame. The bending push block is generally elliptical, and a cable groove is opened on the outer wall of the bending push block. A ceramic plate is fixedly connected to the inner wall of the cable groove. A support rod is fixedly connected to the side of the extension frame near the first substrate. A universal ball is movably installed at one end of the support rod, and the bottom end of the universal ball abuts against the outer wall of the first substrate.

[0008] Preferably, the displacement mechanism includes a support frame fixedly connected to the inner sidewalls of the first substrate and the second substrate. One end of the support frame is fixedly connected to a roller frame, which is X-shaped and has rollers movably mounted at all four ends.

[0009] Preferably, the conveying mechanism includes a pair of bushings fixedly installed inside the first substrate, each bushing having a drive roller movably installed inside it, a drive motor fixedly connected to the inner wall of the first substrate, the drive shaft of the drive motor meshing with the drive rollers through transmission teeth, and a rubber toothed sleeve fitted onto the outer wall of the drive rollers.

[0010] Preferably, the support mechanism includes a pair of support rollers rotatably mounted on the outer side wall of the second substrate, and one end of each pair of support rollers is fixedly connected to an extension roller and a positioning roller shaft.

[0011] Preferably, the support roller is frustoconical, and the outer wall of the support roller is fixedly connected with rubber anti-slip teeth, and the support roller has the same structural shape as the extension roller.

[0012] Preferably, a servo motor is fixedly connected to the inner sidewall of the first substrate, and the drive teeth of the servo motor mesh with the threaded grooves of the lead screw between the first substrate and the second substrate.

[0013] Beneficial effects:

[0014] 1. This utility model utilizes a bending push block installed in a positioning slot at one end of the extension frame. This positioning slot provides support and a limiting effect for the bending push block, preventing excessive force concentration and deformation of the bending push block due to the small contact area between the extension frame and the bending push block, thus avoiding damage. Furthermore, the positioning slot provides a limiting and anti-slip function for the bending push block, preventing it from tilting and detaching from the extension frame under stress. During replacement and installation, the positioning slot guides the bending push block, facilitating quick insertion into the extension frame along the slot and improving the ease of maintenance and replacement.

[0015] 2. The side guard fixedly connected to one side of the bending push block in this utility model can provide lateral support to the bending push block using a side guard made of hard plastic material. This prevents the bending push block from being over-deformed and damaged after the signal cable comes into contact with the bending push block and generates pressure. Moreover, when the bending push block deforms to the other side, the side guard can provide a reverse pulling force to the bending push block, reducing the deformation strength of the bending push block.

[0016] 3. This utility model, through the connection method of the first substrate and the second substrate, can drive the threaded screw between the first substrate and the second substrate to rotate, and then use the threaded screw and guide rod to adjust the distance between the first substrate and the second substrate, thereby extending the distance between the pair of shaping mechanisms. When the distance between the pair of shaping mechanisms changes, the bending length of the S-bend formed by the pressure bending of the signal cable will change, which helps to increase the S-bend length of the signal cable, reduce the deformation of the signal cable, and avoid damage to the signal cable due to excessive bending.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] Reference Figures 1-5 A device for storing spare signal cables in a cable trough includes a first base plate 1 and a second base plate 2. The first base plate 1 is movably connected to one end of the second base plate 2 via a threaded screw and a guide rod. Shaping mechanisms 3 are alternately installed on both sides of the first base plate 1 and the second base plate 2, and the shaping mechanisms 3 are used to bend and shape the signal cables. A conveying mechanism 5 is provided on the outer wall of the first base plate 1, and the conveying mechanism 5 is used to position and convey the signal cables. A supporting mechanism 6 is provided on the outer wall of the second base plate 2, and the supporting mechanism 6 is used to limit and drag the signal cables. A displacement mechanism 4 is provided on the inner sidewall of both the first base plate 1 and the second base plate 2, and the displacement mechanism 4 is used to move the first base plate 1 and the second base plate 2.

[0027] The No. 1 base plate 1 and the No. 2 base plate 2, connected by a threaded screw and a guide rod, can have their spacing adjusted by rotating the threaded screw as needed, thereby changing the bending spacing of the signal cable to meet the adjustment requirements of the cable bending spacing. The conveying mechanism 5 set on the outer wall of the No. 1 base plate 1 can limit and fix the signal cable to complete the bending operation, and can also use friction to convey the signal cable for connection bending operation. The shaping mechanism 3, which is installed alternately on both sides of the No. 1 base plate 1 and the No. 2 base plate 2, can push part of the signal cable to move and bend the signal cable to form an S-shape to meet the coiling requirements. The supporting mechanism 6 set on the outer wall of the No. 2 base plate 2 can support and transfer the signal cable to prevent displacement of one end of the signal cable, which would affect the bending. At the same time, it can also work with the conveying mechanism 5 to complete the signal cable conveying and improve the stability of the signal cable conveying. The displacement mechanism 4 can facilitate the movement of the No. 1 base plate 1 and the No. 2 base plate 2 inside the cable trough to perform connection bending operation of the cable in the cable trough.

[0028] like Figures 3-5 As shown, the shaping mechanism 3 includes mounting brackets 7 respectively installed on both sides of substrate 1 and substrate 2. An electric push rod 8 is fixedly connected to the outer wall of the mounting bracket 7. An extension bracket 9 is fixedly connected to the telescopic end of the electric push rod 8. A positioning slot 10 is provided at one end of the extension bracket 9. A bending push block 12 is inserted into the positioning slot 10. A side guard 15 is fixedly connected to one side of the bending push block 12. A mounting screw hole 11 is provided through the extension bracket 9. A positioning bolt 16 is rotatably installed inside the side guard 15. One end of the positioning bolt 16 passes through the mounting screw hole 11. The extension bracket 9 is moved by the electric push rod 8. The extension frame 9 moves, thereby causing the bending push block 12 at one end of the extension frame 9 to squeeze the signal cable, thus completing the S-shaped bending operation of the signal cable. The positioning slot 10 opened at one end of the extension frame 9 can increase the support force on the bending push block 12 by utilizing the slot of the positioning slot 10, thereby improving the strength and stability of the bending push block 12. At the same time, the setting of the positioning slot 10 also makes it convenient for the bending push block 12 to be quickly inserted into one end of the extension frame 9 along the slot of the positioning slot 10, improving the installation convenience of the bending push block 12. Meanwhile, the side guard 15 fixedly connected to one side of the bending push block 12 can provide lateral support force for the bending push block 12.

[0029] like Figures 1-5As shown, the side guard 15 is made of hard plastic, and the bending push block 12 is made of soft rubber. The side guard 15 and the bending push block 12 are an integral structure, and the side guard 15 covers the outer wall of the extension frame 9. The bending push block 12 is generally elliptical in shape, and a cable groove is provided on the outer wall of the bending push block 12. A ceramic plate is fixedly connected to the inner wall of the cable groove. The ceramic plate can be lowered. A support rod 13 is fixedly connected to the side of the extension frame 9 near the first base plate 1. A universal ball bearing 14 is movably installed at one end of the support rod 13. The bottom end of the universal ball bearing 14 abuts against the outer wall of the first base plate 1. The side guard 15, made of hard plastic, can provide high-strength support for the bending push block 12. This prevents the bending pusher 12 from deforming and shifting under stress, thus avoiding damage or breakage. Furthermore, the soft rubber material of the bending pusher 12 causes it to deform as the signal cable bends, ensuring it adheres to the cable and increasing the contact area. This prevents a small contact area from causing concentrated stress and potential damage to the cable. The universal ball bearing 14, movably mounted at one end of the support rod 13, provides support to the extension frame 9, preventing excessive stress and bending deformation.

[0030] like Figures 1-2 As shown, the displacement mechanism 4 includes a support frame 17 fixedly connected to the inner sidewalls of the first substrate 1 and the second substrate 2. A roller frame 18 is fixedly connected to one end of the support frame 17. The roller frame 18 is X-shaped, and rollers 19 are movably installed at all four ends of the roller frame 18. Through the roller frame 18 with its X-shaped arrangement at one end of the support frame 17, and the rollers 19 movably installed at the four corners of the roller frame 18, it is convenient for the first substrate 1 and the second substrate 2 to extend the cable trough horizontally inside the cable trough, so as to meet the requirements of continuous bending operation of signal cables and improve the cable coiling efficiency.

[0031] like Figures 1-5 As shown, the conveying mechanism 5 includes a pair of bushings 22 fixedly installed inside the first substrate 1. A drive roller 21 is movably installed inside each of the bushings 22. A drive motor 20 is fixedly connected to the inner wall of the first substrate 1. The drive shaft of the drive motor 20 meshes with the drive roller 21 through transmission teeth. A rubber toothed sleeve is fitted onto the outer wall of the drive roller 21. The drive motor 20 drives the pair of drive rollers 21 to rotate, thereby using the friction of the drive rollers 21 to convey and limit the signal cable passing between the pair of drive rollers 21. The rubber toothed sleeve fitted onto the outer wall of the drive roller 21 greatly increases the friction between the drive roller 21 and the signal cable, preventing the cable from slipping.

[0032] like Figures 1-2As shown, the support mechanism 6 includes a pair of support rollers 23 rotatably mounted on the outer wall of the second substrate 2. One end of each pair of support rollers 23 is fixedly connected to an extension roller 24 and a positioning roller shaft 25. By rotatably mounting the pair of support rollers 23 on the outer wall of the second substrate 2, the bent signal cable can be guided. Moreover, during the bending process of the signal cable, one end of the signal cable can be positioned and supported to prevent displacement of one end of the signal cable, which would affect the bending effect. The extension roller 24 and the positioning roller shaft 25 fixedly connected to one end of the support rollers 23 can work together with the support rollers 23 to limit the signal cable and prevent the signal cable from slipping.

[0033] like Figures 1-2 As shown, the support roller 23 is truncated cone-shaped, and the outer wall of the support roller 23 is fixedly connected with rubber anti-slip teeth. The support roller 23 and the extension roller 24 have the same structural shape. The support roller 23 and the extension roller 24 with the same structural shape can form a truncated cone column with a cable groove, which adds a limiting effect when supporting the signal cable.

[0034] like Figures 1-2 As shown, a servo motor 26 is fixedly connected to the inner wall of substrate 1. The drive teeth of the servo motor 26 mesh with the threaded groove of the threaded rod between substrate 1 and substrate 2. By fixing the servo motor 26 to the inner wall of substrate 1, the threaded rod between substrate 1 and substrate 2 can be rotated. Then, the threaded rod and guide rod are used to adjust the distance between substrate 1 and substrate 2.

[0035] The working principle of this utility model is as follows: Base plate 1 and base plate 2 are placed in the cable tray of a cable rack. Depending on the inner wall dimensions of the cable tray, base plate 1 and base plate 2 can be placed at an angle or vertically, ensuring that one set of rollers 19 on the inner sidewalls of base plate 1 and base plate 2 is in contact with the inner wall of the cable tray. Then, the signal cable to be coiled is passed sequentially between a pair of drive rollers 21 and a pair of support rollers 23. Simultaneously, the electric push rods 8 installed on the sides of base plate 1 and base plate 2 are activated, pushing the extension frame 9 to move. The bending push block 12 applies pressure to the signal cable, bending it. Due to the opposing shaping mechanism 3, the bent signal cable forms an S-shape. After the signal cable is bent, the shaping mechanism 3 is reset. Turning on the drive motor 20 drives the drive roller 21 to rotate. The drive roller 21 transports the signal cable, causing the bent signal cable to detach from the entire coiling device via the support roller 23. During the signal cable bending process, according to the bending limit of the signal cable and the coiling requirements, the servo motor 26 can be turned on to drive the threaded screw between the first substrate 1 and the second substrate 2 to rotate. The rotating threaded screw, in conjunction with the guide rod, can expand the distance between the first substrate 1 and the second substrate 2, thereby extending the distance between the pair of shaping mechanisms 3. When the distance between the pair of shaping mechanisms 3 changes, the bending length of the S-bend formed by the pressure-bent signal cable will change, increasing the S-bend length of the signal cable, reducing the deformation of the signal cable, and avoiding damage to the signal cable due to excessive bending.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
