Description

Technical Field

[0001] This utility model belongs to the field of cable installation technology, specifically a cable installation auxiliary bracket. Background Technology

[0002] A cable is a transmission device used to carry electrical energy or signals. It typically consists of several or more conductors tightly wrapped together by specific insulating materials to ensure stable current transmission and safe use. In modern society, cables are widely used, playing a vital role not only in industrial, commercial, and residential sectors but also as an indispensable part of urban infrastructure. To maintain the aesthetics and cleanliness of cities, and to protect cables from environmental damage, modern urban planning often employs various measures for cable placement.

[0003] During cable laying, workers typically need to neatly lay the cables on mounting frames. However, once the cables reach a certain length, their position on the frames often becomes unstable, making it impossible to ensure they remain perfectly straight. Even slight bends, when accumulated, result in wasted cable length as they cannot be fully utilized. Furthermore, as cable length increases, the friction between the cable and the mounting frame also increases, significantly increasing the difficulty for workers to drag the cables, thus affecting construction efficiency and the quality of cable laying. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a cable installation auxiliary bracket, which solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable installation auxiliary bracket, comprising a base plate, two slide rails fixedly connected to the base plate, an M-shaped centering frame slidably connected to the slide rails, two racks fixedly connected to the M-shaped centering frame, a support plate fixedly connected to the base plate, two telescopic rods fixedly connected to the support plate, a pulley frame fixedly connected to one end of each telescopic rod, a threaded sleeve fixedly connected to the bottom of the pulley frame, a threaded rod rotatably connected to the base plate, a worm gear coaxially fixedly connected to the threaded rod, a pair of supports fixedly connected to the base plate, and a worm gear rotatably connected to the supports.

[0006] As a further embodiment of this utility model, two gears are coaxially and fixedly connected at both ends of the worm gear.

[0007] As a further embodiment of this utility model: the gear meshes with the rack.

[0008] As a further aspect of this utility model: the worm gear meshes with the worm.

[0009] As a further embodiment of this utility model: a pulley is rotatably connected to the pulley frame.

[0010] As a further embodiment of this utility model: the threaded rod is threadedly connected to the threaded sleeve.

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

[0012] 1. This utility model is equipped with a centering mechanism. By using the centering mechanism, construction workers can easily and neatly place the cable on the installation frame. This process significantly reduces the difficulty of laying the cable and makes the whole construction process more convenient and efficient.

[0013] 2. This utility model is equipped with an adaptive pulley mechanism, which has an automatic lifting function. It can move upward continuously until the pulley is in close contact with the cable. In this way, the friction between the cable and the mounting bracket is significantly reduced, thereby improving the operating efficiency and reliability of the entire system.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution:

[0021] A cable installation auxiliary bracket includes a base plate 1, two slide rails 2 fixedly connected to the base plate 1, an M-shaped centering frame 3 slidably connected to the slide rails 2, two racks 4 fixedly connected to the M-shaped centering frame 3, a support plate 5 fixedly connected to the base plate 1, two telescopic rods 6 fixedly connected to the support plate 5, a pulley frame 7 fixedly connected to one end of the telescopic rods 6, a threaded sleeve 8 fixedly connected to the bottom of the pulley frame 7, a threaded rod 9 rotatably connected to the base plate 1, a worm gear 10 coaxially fixedly connected to the threaded rod 9, and a... A pair of supports 11 are provided, with a worm gear 12 rotatably connected to each support 11. Two gears 13 are coaxially fixed to both ends of the worm gear 12, meshing with a rack 4. During construction, the operator first places the mounting frame in the designated position, then places the cable on the M-shaped alignment frame 3. At this time, the height of the M-shaped alignment frame 3 is higher than that of the pulley frame 7, so the weight of the cable is mainly concentrated on the M-shaped alignment frame 3. Due to the wedge-shaped structure of the M-shaped alignment frame 3, the cable will approach the center of symmetry under its own weight, completing the alignment. When the operator drags the cable, friction is generated between the cable and the M-shaped alignment frame 3. This friction drives the M-shaped alignment frame 3 to slide along the guide rail. At this time, the rack 4 on the M-shaped alignment frame 3 also moves, and the meshing gear 13 begins to rotate. The rotation of the gear 13 drives the rotation of the worm gear 12.

[0022] The worm gear 10 meshes with the worm 12. A pulley 14 is rotatably connected to the pulley frame 7. The threaded rod 9 is threadedly connected to the threaded sleeve 8. When the worm 12 rotates, the worm gear 10 meshing with it also rotates. When the worm gear 10 rotates, the threaded rod 9, which is coaxially fixed to it, also rotates. Under the constraint of the telescopic rod 6, the threaded rod 9 and the threaded sleeve 8 rotate relative to each other. As a result, the threaded sleeve 8 begins to rise, and the pulley frame 7, which is fixed relative to the threaded sleeve 8, also rises until the pulley 14 comes into contact with the cable. At this point, the friction between the cable and the mounting bracket changes from sliding friction to rolling friction, and the friction force is significantly reduced. Since the worm gear 10 cannot drive the worm 12 in the reverse direction, the above transmission process is unidirectional, and the pulley frame 7 will not descend under the weight of the cable.

[0023] The working principle of this utility model is as follows:

[0024] During construction, the operator first places the mounting frame in the designated position, and then places the cable on the M-shaped alignment frame 3. At this time, the height of the M-shaped alignment frame 3 is higher than that of the pulley frame 7, so the weight of the cable is mainly concentrated on the M-shaped alignment frame 3. Due to the wedge-shaped structure of the M-shaped alignment frame 3, the cable will approach the center of symmetry under its own weight, completing the alignment. When the operator drags the cable, friction is generated between the cable and the M-shaped alignment frame 3. This friction drives the M-shaped alignment frame 3 to slide along the guide rail. At this time, the rack 4 on the M-shaped alignment frame 3 also moves, and the gear 13 meshing with it begins to rotate. The rotation of the gear 13 drives the rotation of the worm gear 12.

[0025] The worm gear 12 rotates, and the worm wheel 10 meshing with it also rotates. The threaded rod 9, coaxially fixed to the worm wheel 10, also rotates. Constrained by the telescopic rod 6, the threaded rod 9 and the threaded sleeve 8 rotate relative to each other, causing the threaded sleeve 8 to rise. The pulley frame 7, fixed relative to the threaded sleeve 8, also rises until the pulley 14 comes into contact with the cable. At this point, the friction between the cable and the mounting bracket changes from sliding friction to rolling friction, significantly reducing the friction force. Since the worm wheel 10 cannot drive the worm gear 12 in the reverse direction, the above transmission process is unidirectional, and the pulley frame 7 does not descend under the weight of the cable.

[0026] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
