Description

Technical Field

[0001] The utility model belongs to the technical field of winches, in particular to a cable winch with a clutch mechanism. Background Art

[0002] A cable winch is a device used to reel in and out cables or ropes, commonly found on construction sites, ships, lifting equipment and other occasions where cables need to be delivered or reeled in over long distances. It is designed to manage and operate cables easily and safely to prevent winding, entanglement and damage.

[0003] For example, the vehicle-mounted cable winch disclosed in the utility model patent with patent announcement number CN217690311U includes an electric mechanism, a clutch mechanism, a transmission mechanism, a manual mechanism, a retracting mechanism, a support frame and a braking device. The clutch mechanism includes a connecting sleeve and a latch. The latch is pulled out of the connecting sleeve to disconnect the winch from the electric mechanism, thereby switching to manual mode. However, in some emergency situations where the reeling work needs to be stopped, the latch rotates with the connecting sleeve, which makes it inconvenient to disconnect the winch from the drive of the power output device. Therefore, a cable winch with a clutch mechanism is needed, which can quickly disconnect the winch from the power output device when in working condition. Utility Model Content

The winding barrel is made hollow through the barrel wall and the connecting plates at both ends to control the weight of the winch.

[0011] Furthermore, the outer side surface of the reel barrel is provided with a block, and the reel barrel is partitioned by the provided block to wind multiple cables.

[0012] Furthermore, the block includes a clamp, a reinforcement rib and a block ring, the clamp is semicircular, two of the clamps can be spliced ​​and wrapped around the outer side of the drum, the clamp is detachably connected to the drum, a plurality of reinforcement ribs are fixed on the clamp along the circumferential direction of the drum, the block ring is fixedly connected to one end of the reinforcement rib away from the clamp, and the width between the blocks can be adjusted through the detachable clamp.

[0013] Furthermore, a spring 1 is sleeved on the linkage shaft between the fixed block and the shift fork, and a spring 2 is sleeved on the barrel shaft between the clutch bracket and the clutch disc. The provided springs enable the clutch disc to fit the barrel and the bevel block to fit the fixed block at the same time.

[0014] Furthermore, the motor adopts a variable frequency motor, which can adjust the motor speed in a wide range and control the rotation speed of the winch at the same time.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model rotates the bevel block to make it move along the fitted inclined surface, thereby driving the shift fork, and driving the clutch disc through the shift fork, so that the clutch disc is separated from the capstan drum to achieve clutch with the motor output. This action can be operated during the movement of the capstan, so that the drum is quickly disconnected from the power output device. BRIEF DESCRIPTION OF THE DRAWINGS

The clutch bracket 41 is fixed to the bracket 1 by screws. A round hole is provided on the clutch bracket 41. A bearing is clamped and fixed in the round hole. The right end of the bracket 1 is clamped and fixed with a bearing in the same way. The drum shaft 32 The inner rings of two bearings are passed through at both ends to form a rotational connection with the clutch bracket 41 and the bracket 1. The fixed block 42 is integrally connected to the clutch bracket 41. The bevel block 43 is connected to the linkage shaft 44. The linkage shaft 44 passes through the fixed block 42 and is connected to the shift fork 45. The bevel block 43 fits with the fixed block 42 and the fitting surface is an inclined surface. The clutch disc 46 is arranged on the reel shaft 32 between the clutch bracket 41 and the reel barrel 31. A snap-in pin is arranged on the right side surface of the clutch disc 46. The reel barrel 31 is provided with a pin hole corresponding to the snap-in pin. The pin is inserted into the pin hole to form a movable snap connection. The shift fork 45 is connected to the clutch disc 46.

[0025] In this embodiment, an annular groove is formed on the clutch disc 46, and the lower part of the shift fork 45 is slidably connected to the annular groove and can slide in the annular groove.
