Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a winch that is convenient for replacing a hoisting mechanism. Background Art

[0002] A hoisting winch is a device used for vertically lifting or lowering heavy objects, and it is widely used in various construction, mining, and industrial sites. The hoisting winch consists of a winch, a cable, and a hook. The winch serves as the power source, the cable conducts the traction, and the hook is used for connecting the item. Since different hoisting mechanisms need to be used to improve the adaptability of hoisting when hoisting objects of different specifications and shapes.

[0003] At present, most of the hoisting mechanisms of winches on the market adopt threaded connections. When replacing different hoisting mechanisms, it is necessary for people to manually turn the bolts. Since the threaded connection needs to be tightened, there will be a very large number of thread turns, which will cause a problem of time waste during installation or disassembly. Moreover, the thread turns are easily worn due to long-term turning through the threaded connection, resulting in a problem of too short service life. Therefore, a winch that is convenient for replacing a hoisting mechanism is proposed to solve the above problems. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model proposes a winch that is convenient for replacing a hoisting mechanism. Through the provided replacement component, different hoisting mechanisms can be quickly replaced, improving the hoisting efficiency of the winch.

[0005] The technical solution for achieving the purpose of the utility model is: a winch that is convenient for replacing a hoisting mechanism, including a winch body, a cable is arranged on the winch body, one end of the cable is provided with a replacement component, the replacement component includes a sleeve fixedly connected to one end of the cable, a connector is arranged on the inner wall of the sleeve, the bottom end of the connector is fixedly connected with a cross plate through a fixed shaft, both ends of the cross plate are rotatably connected with rotating clamping rods through rotating shafts, rectangular through grooves are formed on the surfaces of the two rotating clamping rods, both ends of the cross plate are respectively arranged inside the corresponding rectangular through grooves, arc grooves are formed on the surfaces of the two rotating clamping rods, and two limiting rods are fixedly connected to the inner wall of the sleeve, and the surfaces of the two limiting rods are respectively adapted to and slidably connected with the inner walls of the corresponding two arc grooves.

[0006] In some embodiments, two L-shaped grooves are formed on the surface of the sleeve, a cross bar is slidably connected to the inner walls of the two L-shaped grooves, and the surface of the cross bar is rotatably connected with the connector through a bearing.

[0007] In some embodiments, two positioning grooves are formed in the inner wall of the sleeve. Positioning plates are slidably connected to the inner walls of the two positioning grooves, and the opposite surfaces of the two positioning plates are fixedly connected to the same hoisting mechanism I, and two clamping grooves are formed in the hoisting mechanism I.

[0008] In some embodiments, the bottom ends of the two rotating clamping rods are respectively adapted to the inner walls of the corresponding two clamping grooves and are detachably connected.

[0009] In some embodiments, the bottom end of the cable is detachably connected to the hoisting mechanism I and the hoisting mechanism II respectively through a replacement component.

[0010] Compared with the prior art, the remarkable advantages of the present utility model are as follows:

[0011] Firstly: By lifting the cross bar upwards, the cross bar is rotated by a certain angle through the bearing and clamped into the highest plane of the L-shaped groove. When the cross bar rises, the connecting head drives the cross plate to rise, and the cross plate drives the two rotating clamping rods to rise. Through the sliding between the arc-shaped groove and the limiting rod, the rotation of the rotating clamping rod can be driven until the rotating clamping rod is just clamped with the clamping groove on the hoisting mechanism I or the hoisting mechanism II, realizing the installation, and thus realizing the function of convenient and rapid disassembly and assembly;

[0012] Secondly: By placing the cross bar at the lowest part of the L-shaped groove, the two rotating clamping rods are in an open state, realizing the disassembly of the hoisting mechanism I or the hoisting mechanism II.

[0013] The problems of the prior art that manual screwing of bolts is required are solved. Since a large number of thread turns are required for a tight threaded connection, time will be wasted during installation or disassembly. Moreover, long-term screwing through threaded connection is likely to cause wear of the thread turns, resulting in a too short service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0022] The present utility model provides a winch for conveniently replacing a lifting mechanism through improvement. The technical solution of the present utility model is as follows:

[0023] As Figures 1 - 4 shown, a winch for conveniently replacing a lifting mechanism includes a winch body 1. A cable 2 is arranged on the winch body 1. The cable 2 is wound around the winch body 1. When the winch body 1 is driven by a motor, the cable 2 realizes winding and unwinding. A reciprocating lead screw is arranged on the winch body 1, which can drive a reciprocating block to realize the uniformity of winding. A roller is arranged on the reciprocating block, which can reduce friction and improve the service life of the cable 2. One end of the cable 2 is provided with a replacement component 3. The replacement component 3 includes a sleeve 301 fixedly connected to one end of the cable 2. A connector 304 is arranged on the inner wall of the sleeve 301. The bottom end of the connector 304 is fixedly connected to a horizontal plate 306 through a fixed shaft. Both ends of the horizontal plate 306 are rotatably connected to a rotating clamping rod 307 through a rotating shaft. The rotating clamping rod 307 is composed of a smooth rod and a protrusion arranged at the bottom end of the smooth rod. The protrusion is adapted to a card slot 310 opened on a lifting mechanism one 4 and a lifting mechanism two 5. Rectangular through grooves are opened on the surfaces of both rotating clamping rods 307. The opening of the rectangular through groove can satisfy the rotation path of the rotating clamping rod 307. Both ends of the horizontal plate 306 are respectively arranged inside the corresponding rectangular through grooves. Arc-shaped grooves 309 are opened on the surfaces of both rotating clamping rods 307. Two limiting rods 308 are fixedly connected to the inner wall of the sleeve 301. The surfaces of the two limiting rods 308 are respectively adapted to and slidably connected to the inner walls of the corresponding two arc-shaped grooves 309. By arranging the arc-shaped groove 309 and the limiting rod 308, the rotating clamping rod 307 can realize angle change, so as to facilitate the installation of the lifting mechanism one 4 or the lifting mechanism two 5.

[0024] As Figure 2As shown, in one embodiment, two L-shaped grooves 302 are formed on the surface of the sleeve 301. A cross bar 303 is slidably connected to the inner walls of the two L-shaped grooves 302. A rubber layer is provided on the surface of the cross bar 303, and a rubber layer is also provided on the inner walls of the L-shaped grooves 302, which can increase the friction. When lifting an object, under the action of gravity and friction, the cross bar 303 is not likely to roll inside the L-shaped groove 302. The surface of the cross bar 303 is rotatably connected to the connector 304 through a bearing 305;

[0025] Two positioning grooves 311 are formed on the inner wall of the sleeve 301. A positioning plate 312 is slidably connected to the inner walls of the two positioning grooves 311. By providing the positioning grooves 311 and the positioning plates 312, the quick and accurate installation of the hoisting mechanism I 4 and the hoisting mechanism II 5 can be realized. The opposite surfaces of the two positioning plates 312 are fixedly connected to the same hoisting mechanism I 4, and two clamping grooves 310 are formed on the hoisting mechanism I 4.

[0026] As Figure 3 and 4 shown, in one embodiment, the bottoms of the two rotating clamping rods 307 are respectively adapted to the inner walls of the corresponding two clamping grooves 310 and are detachably connected;

[0027] The bottom end of the cable 2 is detachably connected to the hoisting mechanism I 4 and the hoisting mechanism II 5 respectively through the replacement assembly 3.

[0028] The specific working method is as follows: When the winch for conveniently replacing the hoisting mechanism replaces the hoisting mechanism, first place the cross bar 303 at the lowest position of the L-shaped groove 302 to make the two rotating clamping rods 307 in an open state. At this time, insert the hoisting mechanism I 4 or the hoisting structure II accurately into the inside of the sleeve 301 through the limitation of the positioning plate 312 and the positioning groove 311. When the positioning plate 312 abuts against the upper inner wall of the positioning groove 311, lift the cross bar 303 upward, rotate the cross bar 303 by a certain angle through the bearing 305 and snap it into the highest plane of the L-shaped groove 302. When the cross bar 303 rises, the connector 304 drives the cross plate 306 to rise, and the cross plate 306 drives the two rotating clamping rods 307 to rise. Through the sliding between the arc-shaped groove 309 and the limiting rod 308, the rotation of the rotating clamping rod 307 can be driven until the rotating clamping rod 307 just engages with the clamping groove 310 on the hoisting mechanism I 4 or the hoisting mechanism II 5, realizing the installation, and thus realizing the function of convenient, quick disassembly and assembly.
