Description

Technical Field

[0001] The utility model relates to the technical field of cable construction facilities, in particular to a cable pay-off wheel brake machine. Background Art

[0002] During the construction and maintenance of power lines, cable laying is a crucial step. In traditional cable pay-off operations, the free rotation of the pay-off wheel is often difficult to accurately control. Especially when laying long-distance and heavy cables, it is easy for the pay-off speed to be too fast, resulting in cable entanglement, excessive pulling, or even breakage. In addition, there is a lack of effective braking mechanism due to the need for emergency stopping, which affects construction safety and progress. Therefore, it is particularly important to develop a cable pay-off wheel brake.

[0003] The reference announcement number CN215558025U is a cable pay-off machine brake device, which 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 in the middle position of the annular side of the transmission shaft, and an extension plate is welded on the upper side of the right end surface of the fixed plate. A ball screw is arranged on the right side inside the extension plate, and the front sliding seat is meshed with the front side of the annular side of the ball screw. The front vertical plate is welded in the middle position of the lower end surface of the front sliding seat, and the front brake pad is installed on the rear side of the front vertical plate. This design solves the problem that the original cable pay-off machine does not have the ability to synchronously clamp and brake, which easily causes the cable to become entangled. The device has a reasonable structure, has the ability to synchronously clamp and brake, and is easy to disassemble and replace, and is highly convenient to use. According to the above, although the device can be well applied, it needs to be operated by rotating the wheel multiple times, which is time-consuming and labor-intensive. When facing an emergency, the operator cannot brake quickly according to the dangerous situation, which often troubles the user. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that operators are unable to brake quickly according to dangerous situations when facing sudden emergency situations.

[0005] To achieve the above-mentioned purpose, the utility model provides a cable pay-off reel brake machine, comprising a support frame, a brake plate and a lever;

[0006] The supporting frame comprises a base and a vertical frame, wherein the vertical frame is fixedly arranged on the upper end of the base;

[0007] The brake plate has a brake plate pin hinged to the upper end of the vertical frame at the right end and a slide at the lower end;

[0008] The lever comprises a handle and a swing arm, the handle and the swing arm are fixedly connected, a lever pin is arranged at the connection to hinge the lower end of the vertical frame, and a swing arm shaft is arranged at the outer end of the swing arm to be slidably arranged in a slide groove.

[0009] As a preferred solution, reinforced plates are provided on both sides of the vertical frame for fixing and connecting bases.

[0010] As a preferred solution, a lifting ring is provided at the top of the vertical frame.

[0011] As a preferred solution, a rubber plate for increasing friction is fixedly provided on the top of the brake plate.

[0012] As a preferred solution, the angle between the handle and the swing arm is 120 degrees to 160 degrees.

[0013] As a preferred solution, the handle includes a vertical section and a horizontal section for easy gripping, and the vertical section and the horizontal section are fixedly connected by an arc-shaped connecting section.

[0014] Beneficial effects of the utility model:

[0015] By introducing a lever structure to optimize the operation of the brake pads, this design significantly improves the convenience and safety of the cable reel brake machine. Specifically, the use of the lever structure greatly reduces the force required by the operator to lift the brake pads. This is because the lever principle can amplify the force applied to the handle. With the addition of the lever structure, the lifting and release of the brake pads becomes faster. This labor-saving feature not only reduces the operator's labor intensity, but also improves operational efficiency. In situations where emergency braking is required to prevent cable entanglement, excessive pulling, or breakage, the rapid brake response ensures that possible damage and safety accidents are avoided during the cable reeling process.
