[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0023] like Figure 1-Figure 5 As shown, this utility model provides a technical solution: a dispatching winch drum transmission device, including a base 1 and a mounting frame 2. The top of the base 1 and the bottom of the mounting frame 2 are fixedly connected. A motor 11 is movably mounted on the top of the base 1. The output shaft of the motor 11 is connected to a transmission gear 12. A first gear frame 21 and a second gear frame 22 are fixedly connected to both sides of the mounting frame 2, respectively. A drum 3 is movably mounted on the inner side of the mounting frame 2. A shaft 4 is movably mounted inside the drum 3. An installation groove 301 is opened inside the drum 3. A slot 302 is opened on the inner wall of the installation groove 301. A mounting surface 4 is fixedly connected to the surface of the shaft 4. A hexagonal block 42 is fixedly connected to one side of the outer wall of the scroll 4, and a limit block 43 is movably connected to one side of the hexagonal block 42. A first mounting cover 5 is movably installed on one side of the outer wall of the first gear frame 21, and a second mounting cover 6 is movably installed on one side of the outer wall of the second gear frame 22. The surface of the scroll 4 moves through the interior of the mounting groove 301. The block 41 is located inside the slot 302. The two ends of the scroll 4 are located on the outside of the first gear frame 21 and the second gear frame 22, respectively. A bearing sleeve 51 is fixedly installed on the inside of the first mounting cover 5, and one end of the scroll 4 is movably installed on the inside of the bearing sleeve 51.

[0024] In this embodiment, by installing a spool inside the drum 3, the locking block 41 on the surface of the spool 4 is located inside the locking groove 302, enabling the spool 4 to drive the drum 3 to rotate. The two ends of the spool 4 are respectively installed inside the first mounting cover 5 and the second mounting cover 6. The bearing sleeve 1 51 and the bearing sleeve 2 61 support the two ends of the spool 4 respectively. The first mounting cover 5 and the second mounting cover 6 are both installed by bolts, so that the first mounting cover 5 and the second mounting cover 6 can be removed. The spool 4 is movably installed inside the mounting groove 301 of the drum 3. When the first mounting cover 5 is removed, the spool 4 is pulled outward, so that the drum 3 can be easily taken out from the inside of the mounting frame 2. Example

[0025] like Figure 1-Figure 5 As shown, a screw 44 is fixedly connected to one side of the limiting block 43. The surface of the screw 44 is threadedly connected to the inner wall of the hexagonal block 42. A bearing sleeve 61 is fixedly installed inside the second mounting cover 6. The other end of the roller 4 is movably installed inside the bearing sleeve 61. The other end of the roller 4 movably passes through the interior of the second mounting cover 6. The hexagonal block 42 is located outside the second mounting cover 6. A driven gear 13 is movably installed on the surface of the hexagonal block 42. The top of the transmission gear 12 meshes with the bottom of the driven gear 13.

[0026] In this embodiment, the hexagonal block 42 at one end of the spool 4 is located at the outer end of the second mounting cover 6. The driven gear 13 mounted on the surface of the hexagonal block 42 meshes with the transmission gear 12, enabling the motor to drive the spool 4 to rotate. At the same time, the spool 4 drives the drum 3 to rotate, thus winding and pulling the equipment. The limiting block 43 on one side of the hexagonal block 42 can limit the driven gear 13. The limiting block 43 is connected to the hexagonal block 42 by the screw 44, so that the limiting block 43 can be removed by rotating it. At this time, the spool 4 can be pulled outward, so that the motor 11 does not need to be removed when disassembling the drum 3.

[0027] The working principle of this embodiment is as follows: By installing a spool inside the drum 3, the locking block 41 on the surface of the spool 4 is located inside the locking groove 302, enabling the spool 4 to drive the drum 3 to rotate. Bearing sleeve 1 51 and bearing sleeve 2 61 support the two ends of the spool 4 respectively. The driven gear 13 installed on the surface of the hexagonal block 42 meshes with the transmission gear 12, enabling the motor to drive the spool 4 to rotate. At the same time, the spool 4 drives the drum 3 to rotate, thus winding and pulling the equipment. The limiting block 43 can be removed by rotating it, and the driven gear 13 can be removed from the surface of the hexagonal block 42. Then, the first mounting cover 5 and the second mounting cover 6 can be removed, allowing the spool 4 to be pulled outwards, and the drum 3 to be taken out from the inside of the mounting frame 2. This eliminates the need to remove the motor 11 when disassembling the drum 3, improving the efficiency of installing and disassembling the drum 3.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
