Description

Technical Field

[0001] The utility model relates to the technical field of fork winches, in particular to a braking device for a fork winch. Background Art

[0002] As we all know, during the cable production process, a fork twisting machine is needed to twist multiple strands of cables to form large strands of cables. Fork twisting machines have been widely used in the cable production field.

[0003] Although the existing technical solutions are not prone to wire breakage and are easy to carry, some problems may occur during the cable twisting process of the fork twister, such as cable breakage, foreign objects being stuck or the twisting is completed. At this time, the fork twister needs to be stopped. Since the distribution disk has a certain inertia, the distribution disk will still drive the twisted wire to rotate to a certain extent after the motor stops. The above-mentioned existing technology is not convenient for emergency braking of the fork twister, which may cause the cable breakage or jamming to worsen.

[0004] An existing patent (publication number: CN 217544249 U) discloses a braking device for a fork twisting machine for cable production, including a fork twisting machine body, which can drive the main shaft and the distribution disk to rotate through a first motor and a transmission belt to twist the cables. Turning off the first motor can stop the driving action on the main shaft, and the adjusting rod can be driven to rotate by the second motor. Through the threaded cooperation of the moving plate and the adjusting rod and the limiting action of the transmission box on the moving plate, the two locking rings can be driven to approach each other through the two moving plates, and the gears can be clamped through the tooth blocks to brake the main shaft. The conveyor belt can be clamped through the clamping mechanism to stop the transmission belt from rotating, thereby performing emergency braking on the fork twisting machine. Compared with the above-mentioned prior art, this scheme facilitates emergency braking of the fork twisting machine.

[0005] However, the above technical solution still has certain defects. The transmission belt and the outer wall gear of the main shaft are clamped and braked by saw teeth, and the transmission is clamped by saw teeth, which can easily cause abnormal wear of the transmission belt and greatly shorten the life of the transmission belt. At the same time, when the saw teeth clamp the gears, the main shaft speed is too fast, causing the saw teeth to break. Therefore, a braking device for a fork winch is proposed.
