Description

Technical Field

[0001] This utility model specifically relates to a cable laying device that is easy to move. Background Technology

[0002] In power grid construction, maintenance, and various cable laying projects, track-mounted cable laying frames are a commonly used basic piece of equipment, used to support cable reels and guide the smooth release of cables. Traditional track-mounted cable laying frames typically consist of two side-by-side frame bodies, a connecting threaded rod, and cable laying rollers mounted on them.

[0003] However, in actual construction applications, the existing overall structure is bulky and lacks an effective moving mechanism at the bottom. When the work position needs to be adjusted, it often requires the use of hoisting equipment or multiple people to pry it, which is extremely inconvenient and seriously affects the construction efficiency. In addition, during the movement of the traditional cable laying frame, its cable laying rollers are in a free-rotating state, and the rollers will drive the cable reel on it to rotate together, which can easily cause the cable to loosen and become disordered, affecting the use of cable laying. Therefore, we propose a cable laying device that is easy to move. Utility Model Content

[0004] The purpose of this invention is to provide a cable laying device that is easy to move, so as to solve the problems mentioned in the background art.

Detailed Description of the Embodiments

[0025] 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 scope of protection of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a portable cable laying device, comprising:

[0027] Two wire feeding frames 1 arranged side by side;

[0028] A connecting threaded rod 2 is positioned between two wire feeding frames 1, and a nut is provided on the outer surface of the connecting threaded rod 2;

[0029] The wire feeding rollers 3 are rotatably mounted on both ends of the inner side of the wire feeding frame 1;

[0030] A rotating shaft 4 is rotatably mounted on one side wall of the wire feeding frame 1, and a moving wheel 5 is fixed on the lower surface of the rotating shaft 4 to drive the wire feeding frame 1 to move.

[0031] The mobile wheels 5 can be quickly deployed when movement is needed, and the brakes are automatically triggered to ensure safe movement. When laying lines at a fixed point, the mobile wheels 5 can be retracted to enhance the stability of the device, effectively prevent accidental movement, and significantly improve the ease of operation, safety, and work efficiency of the equipment.

[0032] Braking assembly 6 is located at the end of the rotating shaft 4 to brake the wire feeding roller 3 when the wire feeding frame 1 is moved;

[0033] To prevent the pay-off roller 3 from rotating accidentally during movement;

[0034] An adjustment component is provided on the rotating shaft 4 to rotate and adjust the position of the rotating shaft 4;

[0035] The position of the rotating shaft 4 can be adjusted to make the moving wheel 5 contact the ground, or the moving wheel 5 can be folded up to be close to the wire feeding frame 1.

[0036] In this embodiment, preferably, the adjustment component includes an adjustment handle 9 and a first socket 10. The adjustment handle 9 is slidably disposed on the inner side of the rotating shaft 4, and a first socket 10 that is interference-fitted with the adjustment handle 9 is provided on one side wall of the wire feeder body 1.

[0037] This allows for quick locking of the position of the rotating shaft 4 after adjustment. Alternatively, the position of the adjusting handle 9 can be fixed using existing latches or bolts, thus completing the locking of the rotating shaft 4 after adjustment.

[0038] In this embodiment, preferably, the adjustment assembly further includes a fixing plate 11, the fixing plate 11 is fixed to a side wall of the pay-off frame body 1, and a second insertion hole having the same shape as the end of the adjustment handle 9 is penetratingly opened on the inner side of the fixing plate 11;

[0039] It is convenient to lock the position of the adjustment handle 9 when the adjustment handle 9 is in the vertical state.

[0040] In this embodiment, preferably, the adjustment handle 9 is in a "匚"-shape.

[0041] In this embodiment, preferably, the braking assembly 6 includes an adjustment rod 12, a braking steel wire rope 13, a friction plate 14 and a return spring 15. The adjustment rod 12 is rotatably mounted at the end of the rotating shaft 4, the friction plate 14 is arranged on the adjustment rod 12 through the braking steel wire rope 13, one side of the pay-off frame body 1 is provided with a support plate for guiding the braking steel wire rope 13, the return spring 15 sleeved outside the braking steel wire rope 13 is arranged on the support plate, and one end of the return spring 15 is in contact with the friction plate 14;

[0042] Through pure mechanical linkage braking, when the rotating shaft 4 rotates to lower the moving wheel 5, the friction plate 14 is automatically pulled to implement braking, no extra operation is required, the response is rapid, and the reliability is high. The return spring 15 ensures that the braking can be automatically and timely reset when the moving state is released, so as to avoid interference with normal pay-off.

[0043] In this embodiment, preferably, the friction plate 14 is arc-shaped;

[0044] It is convenient to form a larger contact area, so as to achieve better braking friction force.

[0045] In this embodiment, preferably, the moving wheel 5 is provided with a connecting block 7, and the connecting block 7 is fixedly matched with the rotating shaft 4;

[0046] It is convenient to improve the firmness of connection.

[0047] The working principle and application process of the present utility model are as follows: when in use, the rotating shaft 4 is driven to rotate by the adjustment handle 9, the rotating shaft 4 drives the moving wheel 5 to contact the ground. Since the adjustment rod 12 is arranged at the end edge of the rotating shaft 4, the adjustment rod 12 is driven to move downward when the rotating shaft 4 rotates, at this time the friction plate 14 can be pulled to move downward through the braking steel wire rope 13, the return spring 15 is compressed by the extrusion between the friction plate 14 and the support plate, the friction plate 14 moves downward to contact the shaft rod at the end of the pay-off roller 3, so as to brake the pay-off roller 3. Meanwhile, the adjustment handle 9 is inserted into the inner side of the first insertion hole 10, so the position of the rotating shaft 4 can be locked, thereby it is convenient to move the pay-off frame on the pay-off frame body 1 through the adjustment rod 12, and adjust the position of the pay-off frame.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
