Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a winch which is easy to move. Background Art

[0002] A winch is a small and light lifting equipment that uses a drum to wrap a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically and pull heavy objects horizontally or at an angle. The winch is divided into three types: manual winch, electric winch and hydraulic winch. The electric winch is the main one and can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used due to its simple operation, large rope winding capacity and easy relocation.

[0003] According to the disclosed electric winch that is easy to move (publication number: CN213171243U), the above application uses a moving plate, a slide plate, a pulley, a tooth groove, a limit turn bar, a baffle and a pushing handle in coordination. When pulling objects, the pushing handle on one side of the baffle can be pushed to move the pulley along the slide plate. After adjusting the position, the limit turn bar is rotated to make it stuck in the tooth groove to fix the moving plate, thereby playing the role of a movable fine-tuning winch when pulling objects. Through the setting of the moving wheel, the purpose of easy movement is achieved.

[0004] However, when the winch is used to reel in the wire rope by using the fixed pulley, since the fixed pulley is fixedly installed on the outer wall of the support column, the wire rope often becomes tangled when being reeled in on the winch, requiring manual trimming, which is not only inefficient but also increases the workload of employees. Utility Model Content

[0024] Specifically, the guide device 2 of the technical solution of the utility model includes a driving motor 201, a reciprocating screw rod 202, a fixed pulley 203, a guide block 204 and a hook 205. The driving motor 201 drives the reciprocating screw rod 202 to rotate, so that the fixed pulley 203, the guide block 204 and the hook 205 on the outer wall of the reciprocating screw rod 202 move back and forth left and right, which has a traction effect on the wire rope and ensures that the wire rope is wound neatly and orderly.

[0025] In one embodiment of the present invention, a limit torque is provided on the outer wall of the first set of columns 101 and the second set of columns 102 , which can limit the up and down movement of the second set of columns 102 and the lifting rod 103 .

[0026] Please continue reading Figure 1-Figure 3A guide rod 3 is fixedly installed on the inner wall of the two sets of lifting rods 103, and a fixed pulley 203 is slidably connected to the outer wall of the guide rod 3. A limiting device 4 is arranged on the outer wall of the fixed pulley 203. The limiting device 4 includes a fixed block 401, a limiting rod 402 and a limiting spring 403. The fixed block 401 is fixedly installed on the outer wall of the fixed pulley 203. A sliding groove is provided on the fixed block 401. The limiting rod 402 is slidably connected in the sliding groove. The end of the limiting rod 402 away from the fixed pulley 203 is in contact with the limiting spring. The spring 403 is fixedly connected, and one end of the limit spring 403 away from the limit rod 402 is fixedly connected to the inner wall of the slide groove. A winch 5 is arranged on the upper end of the base plate 1, and a positioning block 6 is fixedly installed on the outer wall of the base plate 1. A threaded rod passes through the positioning block 6 and is threadedly connected with the threaded rod.

Universal wheels are fixedly installed around the bottom of the base plate 1. The universal wheels facilitate the movement of the entire device and improve the convenience of using the device.

[0027] In order to prevent foreign matter and garbage from adhering to the outer wall of the wire rope during the winding process, two sets of hooks 205 are fixedly installed on the outer wall of the guide block 204. The hooks 205 can clean the foreign matter and garbage adhering to the outer wall of the wire rope, thereby ensuring the cleanliness of the wire rope and improving the winding effect.

[0028] In order to prevent the winch 5 from winding the wire rope at too high a speed, causing the wire rope to fall off from the fixed pulley 203, a limiting device 4 is provided to limit the wire rope inside the fixed pulley 203, thereby ensuring normal winding of the wire rope.

[0029] During operation (or use), when the wire rope needs to be reeled in, the two sets of limit rods 402 are pulled outward in opposite directions, and the wire rope is placed inside the fixed pulley 203. After the limit rods 402 are released, the elastic potential energy of the limit springs 403 causes the two sets of limit rods 402 to slide toward each other and press against each other, and the winch 5 is started to reel in the wire rope. At this time, the drive motor 201 is started, so that the output end of the drive motor 201 drives the reciprocating screw rod 202 to rotate, and the fixed pulley 203 on the outer wall of the reciprocating screw rod 202 also moves back and forth left and right, driving the wire rope to move repeatedly left and right, which has a traction effect on the reeling of the wire rope, ensures that the wire rope is reeled in an orderly manner, and improves the reeling effect of the wire rope.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
