Description

Technical Field

[0001] This utility model relates to the field of power construction and cable laying technology, specifically a cable laying reel brake. Background Technology

[0002] In the construction and maintenance of power lines, cable laying is a crucial step. In traditional cable laying operations, the free rotation of the laying reel is often difficult to control precisely, especially when laying long-distance, heavy cables. This can easily lead to problems such as excessive laying speed causing cable entanglement, excessive pulling, or even breakage. Alternatively, there may be a lack of effective braking mechanisms when emergency stops are needed, affecting construction safety and progress. Therefore, developing a cable laying reel brake is of particular importance.

[0003] A cable-laying machine braking device, as described in reference announcement number CN215558025U, includes an extension plate, a ball screw, a brake disc, a front sliding seat, a front vertical plate, and a front brake pad. The brake disc is welded to the middle of the annular side of the drive shaft. An extension plate is welded to the upper right side of the fixed plate. A ball screw is located inside the right side of the extension plate. The front sliding seat engages with the front annular side of the ball screw. A front vertical plate is welded to the middle of the lower end face of the front sliding seat. A front brake pad is installed on the rear side of the front vertical plate. This design solves the problem of existing cable-laying machines lacking synchronous clamping braking capability, which easily leads to cable tangling. This device has a reasonable structure, synchronous clamping braking capability, and is easy to disassemble and replace, making it highly convenient to use. However, while this device can be well applied, it is generally not convenient for automated elastic braking of the pay-off reel, causing inconvenience during braking of the pay-off reel and frequently troubling users. Utility Model Content

[0004] The purpose of this utility model is to provide a cable reel brake to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to automatically perform elastic braking on the reel, which makes the reel component have certain inconveniences during the braking process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable reel brake machine, comprising a base frame, uprights on both sides of the top of the base frame, an I-beam frame at the top of the uprights, a base frame at the top of the two I-beam frames, side frames on both sides of the top of the base frame, a rotating shaft rotatably mounted on the upper inner wall between the side frames, circular baffles on both sides of the outer walls of the rotating shaft, a plurality of hexagonal bolts on the outer wall of one of the circular baffles, a flower-shaped brake plate on the side of the hexagonal bolts away from the circular baffle, a plurality of hexagonal nuts on the outer wall of the flower-shaped brake plate, one end of the hexagonal nut penetrating the flower-shaped brake plate and threadedly connected to the hexagonal bolt, a first connecting frame at the top of the base frame below the flower-shaped brake plate, a linkage arm rotatably mounted on the outer wall of the first connecting frame, a brake wheel rotatably mounted on one side of the top of the linkage arm via a bracket, the outer wall of the brake wheel contacting the outer wall of the flower-shaped brake plate.

[0006] Preferably, four casters are installed at the corners of the bottom of the base frame to facilitate the transport and transfer of the entire brake unit.

[0007] Preferably, a nut seat is provided on the outer wall of the base frame on one side of the universal wheel. The nut seat is arranged in an L-shaped structure to facilitate the placement of the screw component.

[0008] Preferably, a screw is threadedly installed at the bottom of the nut seat, and the bottom end of the screw extends to the outside of the nut seat and is rotatably mounted with an anti-slip foot. With the anti-slip foot, when the anti-slip foot moves down and contacts the ground, the brake can be anti-slip positioned.

[0009] Preferably, a wire feeding wheel body is fitted on the outer wall of the rotating shaft between the circular baffles. Both ends of the wire feeding wheel body are connected to the inner wall of the circular baffles. The wire feeding wheel body is provided to enable the winding and unwinding of the cable.

[0010] Preferably, a spring telescopic component is installed on one side of the bottom end of the linkage arm, and a second connecting frame is rotatably installed on the end of the spring telescopic component away from the linkage arm. The bottom end of the second connecting frame is connected to the inner wall of the base frame. The spring telescopic component applies an upward elastic pressure to the linkage arm so that the brake wheel always abuts against the outer wall of the flower-shaped brake plate to perform elastic braking operation on the wire feeding wheel body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the cable reel brake not only achieves the purpose of automatically and elastically braking the reel body to improve the convenience of using the brake, but also achieves the purpose of easy and convenient transportation and stable installation of the brake.

[0012] The spring telescopic component has good elasticity, which allows it to apply upward elastic pressure to the linkage arm. This causes the linkage arm to move the brake wheel upward and abut against the outer wall of the flower-shaped brake plate. Since the flower-shaped brake plate is bolted to the outer wall of the circular baffle and the circular baffle is installed at both ends of the wire feeding wheel body, the purpose of automatically and elastically braking the wire feeding wheel body can be achieved, thereby improving the convenience of using the brake machine.

[0013] With several casters, the brake unit can be transported as a whole when the base frame is pushed. By rotating the screw, the screw is located at the bottom of the nut seat and rotates and slides, so that the screw drives the anti-slip feet to rise and fall. When the anti-slip feet fall down and contact the ground, the brake unit can be anti-slip, thus achieving the purpose of easy and convenient transportation and stable placement of the brake unit.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-4 One embodiment of this utility model is a cable unloading wheel brake, which includes a base frame 1, and four casters 2 are installed at the corner positions at the bottom of the base frame 1.

[0021] When in use, the universal wheels 2 are used to transport and move the entire brake unit.

[0022] Nut seats 3 are provided on the outer wall of the base frame 1 on one side of the caster wheel 2. The nut seats 3 are arranged in an L-shaped structure.

[0023] In use, the nut seat 3 is provided to accommodate the screw rod 4.

[0024] A screw rod 4 is threadedly installed at the bottom of the nut seat 3. The bottom end of the screw rod 4 extends to the outside of the nut seat 3 and is rotatably mounted with an anti-slip foot 5.

[0025] In use, the anti-slip support 5 is installed so that the brake can be anti-slip positioned when it moves down to contact the ground.

[0026] The base frame 1 has uprights 6 on both sides of the top, and I-shaped frames 7 on the top of the uprights 6. The two I-shaped frames 7 have base frames 8 on the top. The base frames 8 have side frames 9 on both sides of the top. A rotating shaft 10 is rotatably installed on the upper inner wall between the side frames 9. Circular baffles 12 are fitted on the outer walls of both sides of the rotating shaft 10. A wire feeding wheel body 11 is fitted on the outer wall of the rotating shaft 10 between the circular baffles 12. Both ends of the wire feeding wheel body 11 are connected to the inner wall of the circular baffles 12.

[0027] In use, the cable is wound up and unwound by the cable reel body 11.

[0028] A circular baffle 12 has several hexagonal bolts 20 on its outer wall. A flower-shaped brake plate 13 is provided on the side of the hexagonal bolts 20 away from the circular baffle 12. Several hexagonal nuts 19 are installed on the outer wall of the flower-shaped brake plate 13. One end of the hexagonal nut 19 passes through the flower-shaped brake plate 13 and is threadedly connected to the hexagonal bolts 20. A first connecting frame 17 is provided at the top of the base frame 8 below the flower-shaped brake plate 13. A linkage arm 14 is rotatably installed on the outer wall of the first connecting frame 17. A spring telescopic member 16 is installed on one side of the bottom end of the linkage arm 14. A second connecting frame 18 is rotatably installed on the end of the spring telescopic member 16 away from the linkage arm 14. The bottom end of the second connecting frame 18 is connected to the inner wall of the base frame 8.

[0029] In use, the spring telescopic member 16 applies an upward elastic pressure to the linkage arm 14 so that the brake wheel 15 always abuts against the outer wall of the flower-shaped brake plate 13 to perform elastic braking operation on the wire feeding wheel body 11.

[0030] A brake wheel 15 is rotatably mounted on one side of the top of the linkage arm 14 via a bracket, and the outer wall of the brake wheel 15 contacts the outer wall of the flower-shaped brake plate 13.

[0031] In this embodiment, the brake unit is first transported by pushing the base frame 1 using several casters 2. Then, by rotating the screw 4, the screw 4 rotates and slides at the bottom of the nut seat 3, causing the anti-slip feet 5 to rise and fall. When the anti-slip feet 5 touch the ground, the brake unit is anti-sliply positioned. The rotating shaft 10 is then mounted on the inner wall of the side frame 9. A wire feeding wheel body 11 is mounted on the outer wall of the rotating shaft 10, and circular baffles 12 are located at both ends of the wire feeding wheel body 11, allowing the cable to be wound and unwound effectively from the outer wall of the wire feeding wheel body 11. The reel body 11 can rotate synchronously with the rotating shaft 10 to wind and unwind the cable. Finally, the spring telescopic member 16 has good elasticity, so that the spring telescopic member 16 applies upward elastic pressure to the linkage arm 14, so that the linkage arm 14 drives the brake wheel 15 to move upward and abut against the outer wall of the flower-shaped brake plate 13. Since the flower-shaped brake plate 13 is bolted to the outer wall of the circular baffle 12 and the circular baffle 12 is installed at both ends of the reel body 11, the reel body 11 can be automatically elastically braked to reduce the phenomenon of excessive rotation of the reel body 11 due to inertia during rotation, thus completing the use of the reel brake machine.
