[0002] A winch is an important mechanical lifting and traction device. It typically consists of one or more vertically mounted drums that wind up, but do not store, rope or chain under power to perform lifting or traction operations. Winches have various power sources, including electric, hydraulic, manual, and PTO (power output via a transfer case), allowing them to adapt to different application scenarios and needs. Whether in self-rescue and mutual rescue operations in vehicles such as off-road vehicles, agricultural vehicles, and yachts, or in heavy-duty lifting and loading / unloading operations in construction, mining, and logistics, winches play a vital role. Furthermore, winches are compact, easy to operate, and safe and reliable, making them an indispensable safety device in many industries, including military, police, petroleum, environmental protection, and forestry.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a winch structure that is easy to replace, including a fixed base plate 1. A first support plate 101 is fixedly connected to one side of the upper end face of the fixed base plate 1. A support tube 102 is fixedly connected to the upper end of the outer end face of the first support plate 101. A second support plate 2 is provided on the other side of the upper end face of the fixed base plate 1. A rectangular connecting plate 201 is fixedly connected to the lower end of the outer end face of the second support plate 2. The rectangular connecting plate 201 and the fixed base plate 1 are fixedly connected by a plurality of first bolts 202. By removing the plurality of first bolts 202, the second support plate 2 can be separated from the fixed base plate 1. A semi-circular bearing support is fixedly connected to the upper end of the outer end face of the second support plate 2. The component 203, the supporting round tube 102 and the semi-circular bearing support 203 are both equipped with bearings 4. The first support plate 101 and the second support plate 2 are rotatably connected to the winch shaft 5. The winch shaft 5 is connected to the winding drum 6. The outer end face of the winch shaft 5 is fixedly connected with the connecting key 501 in an annular array. The inner end face of the winding drum 6 is provided with the keyway 601 in an annular array. The connecting key 501 on the winch shaft 5 slides into the keyway 601 on the inner end face of the winding drum 6. When the second support plate 2 is separated from the fixed base plate 1, the winding drum 6 is pulled to one side to separate the winding drum 6 from the winch shaft 5. Different types of winding drums 6 and their cables can be replaced as needed.

[0024] Please see Figure 2-3 One end of the winch shaft 5 passes through the first support plate 101 and is inserted into the middle of the bearing 4 inside the support tube 102. The other end of the winch shaft 5 passes through the second support plate 2 and is inserted into the middle of the bearing 4 inside the semi-circular bearing support 203. A semi-circular bearing clamping member 3 is connected to the upper end of the semi-circular bearing support 203. The front and rear ends of the semi-circular bearing support 203 and the semi-circular bearing clamping member 3 are fixedly connected by the second bolt 302. The semi-circular bearing support 203 is secured to the semi-circular bearing support 203 by the semi-circular bearing clamping member 3. 03 The upper bearing 4 is pressed. A circular cover 301 is fixedly connected to one side of the semi-circular bearing clamping part 3. Before replacing the winding drum 6 and its cable, first remove the second bolt 302 to separate the semi-circular bearing clamping part 3 from the semi-circular bearing support 203. Pull out the upper bearing 4 of the semi-circular bearing support 203 to separate the upper bearing 4 of the semi-circular bearing support 203 from one end of the winch shaft 5. Then separate the second support plate 2 from the fixed base plate 1, and the winding drum 6 can be pulled out for replacement.

[0025] Please see Figure 2 A drive mechanism 7 is fixedly installed on the upper end of the fixed base plate 1 and on the outside of the first support plate 101. One end of the winch shaft 5 passes through the middle of the bearing 4 inside the support tube 102 and is connected to the output end of the drive mechanism 7 through a coupling.

[0026] Working Principle: In use, the drive mechanism 7 first drives the winch shaft 5 to rotate. The winch shaft 5, through the connecting key 501 on its outer side, engages with the keyway 601 inside the winding drum 6, driving the winding drum 6 to rotate synchronously, thereby realizing the winding or unwinding operation of the cable. When it is necessary to replace different types of winding drums 6 and the cables on them, first stop the operation of the drive mechanism 7, then remove the second bolt 302 to separate the semi-circular bearing clamping part 3 from the semi-circular bearing support part 203. Next, pull out the bearing 4 at the upper end of the semi-circular bearing support part 203 to release one end of the winch shaft 5. Subsequently, remove multiple first bolts 202 to separate the second support plate 2 from the fixed base plate 1. At this time, the winding drum 6, together with one end of the winch shaft 5, can be pulled to one side to separate the connecting key 501 and keyway 601 between the winding drum 6 and the winch shaft 5, thereby realizing the quick replacement of the winding drum 6. After replacement, reassemble by reversing the steps to continue use.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
