Description

Technical Field

[0001] The utility model relates to the field of winch tools, in particular to an electric winch. Background Art

[0002] The electric winch is a commonly used tool at present. Patent publication document CN215974718U discloses an electric winch. When using the electric winch of this structure, one end of the wire rope needs to be fixed on the drum, and the drum winds or releases the wire rope by its own rolling. Since the electric winch of this structure needs to wind the wire rope and fix it on the drum, but since there is no fixed structure on the drum of this winch, the drum of this structure must be fixed by spot welding or clamping to fix one end of the wire rope on the drum. This fixing method is very cumbersome and inconvenient to disassemble. Utility Model Content

[0003] Aiming at the above problems, the utility model provides an electric winch.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An electric winch comprises a first support, a second support, a drum and a connecting frame, wherein the first support and the second support are fixedly matched together by the connecting frame, and the first support and the second support are in a non-contact state, and the two ends of the drum are rotatably matched with the first support and the second support respectively, and the drum wall is provided with a rope threading hole and a locking screw hole, the rope threading hole and the locking screw hole are in a vertical state, and the rope threading hole and the locking screw hole are in a connected state, the rope threading hole is a circular rope threading hole, and a spike is arranged on the hole wall of the rope threading hole; when the rope is located in the rope threading hole, the locking screw hole and the spike are respectively located on both sides of the rope.

[0006] It should be noted that the rope suitable for this type of electric winch is a wire rope, not a fiber rope. In this type of electric winch, the first support, the second support and the connecting frame constitute the frame of the entire electric winch. The drum is arranged between the first support and the second support. A rope threading hole and a locking screw hole are provided on the drum. The locking screw hole is used to install the screw. When in use, the rope is first passed through the rope threading hole, and then the screw is installed on the locking screw hole. The screw is used to tighten the rope. Since sharp objects are provided on the wall of the rope threading hole, these sharp objects will pierce into the rope. Due to the squeezing effect of the screw on the other side of the rope, this is equivalent to the two sides of the rope being clamped and fixed by the screw and the sharp object respectively. Such a design can ensure that the rope is stably clamped in the rope threading hole.

[0007] Specifically, the diameter of the rope adapted by this type of reel is smaller than the diameter of the rope threading hole. When the rope is passed through the rope threading hole, it can be suspended in the air to avoid contact with sharp objects. When the screw is screwed into the locking screw hole, the screw and the sharp object respectively press the rope from both sides. When disassembling, you only need to unscrew the screw and pull the rope so that the sharp object no longer pierces the rope, and then you can take the rope out of the rope threading hole.

[0008] In summary, the electric winch is provided with a rope threading hole and a locking screw hole on the drum, and the rope can be disassembled and assembled by screwing the screw on the locking screw hole, so the disassembly and assembly is convenient and quick.

[0009] Optionally, it further includes a motor, which is arranged on the first support, and the shaft of the motor is matched with the reel.

[0010] The shaft of the motor is matched with the reel, and the function of the shaft of the motor is to drive the reel to rotate.

[0011] Optionally, a protective cover is further included, wherein the protective cover is arranged on the first support, a protective cavity is formed between the protective cover and the first support, and the motor is located in the protective cavity.

[0012] A protection cavity is formed between the protective cover and the first support, and the function of the protection cavity is to protect the motor.

[0013] Optionally, baffles are provided at both ends of the reel, and the baffles are circular baffles, and the baffles at both ends of the reel are in a parallel and non-contacting state.

[0014] The baffle has the function of limiting the position of the rope. The existence of the baffle can prevent the rope on the drum from contacting the first support or the second support, thereby preventing the rope from wearing the first support or the second support.

[0015] Optionally, a circular receiving groove is provided on the first support and the second support, and the blocking piece is located in the receiving groove.

[0016] Optionally, a controller is also included, and the controller is arranged on the connecting frame.

[0017] The specific controller is electrically connected to the motor, and the operation of the motor is controlled by the controller.

[0018] Optionally, the first support and the second support can be detachably matched with the connecting frame.

[0019] Specifically, the first support and the second support are matched with the connecting frame through bolts or screws.

[0020] Optionally, a bearing is further included, and the bearing is arranged between the reel and the first support or between the reel and the second support.

[0021] The function of the bearing is to make the reel more stable when it rotates.

[0022] The utility model has the beneficial effects that: by arranging the rope threading through hole and the locking screw hole on the drum, the rope can be disassembled and assembled by screwing the screw on the locking screw hole, and the disassembly and assembly is convenient and quick.
