DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Figures 1 to 10 An embodiment of the present invention is shown.

[0029] Example: A lightweight and convenient high-horsepower winch includes a base 1, a support assembly 2 is arranged on the upper side of the base 1; a main shaft 3, the main shaft 3 is rotatably mounted on the support assembly 2, and a winch drum 4 is arranged on the outer wall of the main shaft 3; a motor 5, the output shaft of the motor 5 is connected to one end of the main shaft 3 through a shift mechanism; a multi-stage planetary reduction assembly, the multi-stage planetary reduction assembly is installed between the main shaft 3 and the winch drum 4, and is used to reduce the speed of the main shaft 3 and drive the winch drum 4 to rotate around the main shaft 3. The main shaft 3 is driven to rotate by the motor 5, and the main shaft 3 can gradually reduce the output of the high-speed and low-torque motor 5 through the multi-stage planetary reduction assembly to form a low-speed and high-torque output, so that a high-horsepower winch can be formed by only using a relatively small-power motor 5, and heavy objects can be lifted. The multi-stage planetary reduction assembly is used to replace the original parallel shaft gear box and the drum transverse layout structure, which reduces the transverse layout size and reduces the weight of the whole machine.

[0030] The multi-stage planetary reduction assembly includes a first planetary reducer, a second planetary reducer and a third planetary reducer which are sequentially connected in reduction transmission. The motor 5 drives the first planetary reducer, and the third planetary reducer drives the capstan drum 4. The first planetary reducer, the second planetary reducer and the third planetary reducer form a three-stage reduction, which enables the capstan drum 4 to output a sufficiently large horsepower.

[0031] The first planetary reducer includes a first sun gear 6, a first planetary gear 7 and a first inner gear ring 8. The first sun gear 6 is connected to the motor 5 through a shift mechanism. A first planet carrier 9 is provided at one end of the main shaft 3 facing the motor 5. The first planetary gear 7 is mounted on the first planet carrier 9 through a first rotating shaft 10. The first inner gear ring 8 surrounds the first sun gear 6 and is fixedly connected to the support assembly 2. The first planetary gear 7 is arranged between the first sun gear 6 and the first inner gear ring 8. When the motor 5 drives the first sun gear 6 to rotate, the first sun gear 6 and the first planetary gear 7 are in transmission engagement. Since the first inner gear ring 8 is fixedly connected to the support assembly 2, the first planetary gear 7 will rotate and revolve around the first sun gear 6. When the first planetary gear 7 revolves, it will drive the first planet carrier 9 to rotate, thereby driving the main shaft 3 to rotate, and then driving the winch drum 4 to rotate with the help of the second planetary reducer and the third planetary reducer. After the transmission of the first sun gear 6 and the first planetary gear 7, the speed of the motor 5 has been reduced and transmitted to the main shaft 3, and the torque of the main shaft 3 is increased.

[0032] The second planetary reducer is installed at one end of the main shaft 3 away from the motor 5. The second planetary reducer includes a second sun gear 11, a second planetary gear 12 and a second inner ring gear 13. The second sun gear 11 is installed on the outer wall of the end of the main shaft 3. The second inner ring gear 13 surrounds the second sun gear 11 and is fixedly connected to the support assembly 2; the third planetary reducer includes a third sun gear 14, a third planetary gear 15, a third inner ring gear 16 and a second planet carrier 17. The second planet carrier 17 is rotatably installed on the outer wall of the main shaft 3 on the side of the second sun gear 11 toward the motor 5. The second planetary gear 12 is installed on the second planet carrier 17 through the second rotating shaft 18. The second planetary gear 12 is transmission-arranged between the second sun gear 11 and the second inner ring gear 13. The third inner ring gear 16 surrounds the third sun gear 14 and is fixedly connected to the capstan drum 4. The third planetary gear 15 is fixedly connected to the support assembly 2 through the third rotating shaft 40. When the main shaft 3 rotates, the second sun gear 11 is meshed with the second planetary gear 12. Since the second inner gear ring 13 is fixedly connected to the support assembly 2, the second planetary gear 12 will rotate and revolve around the second sun gear 11. When the first planetary gear 7 revolves, it will drive the second planet carrier 17 to rotate around the main shaft 3, thereby driving the third sun gear 14 to rotate. The third sun gear 14 is meshed with the third planetary gear 15. Since the third planetary gear 15 is fixedly connected to the support assembly 2, the third planetary gear 15 will drive the third inner gear ring 16 to rotate when it rotates. With the help of the rotation of the third inner gear ring 16, the winch drum 4 will be driven to rotate, thereby releasing and collecting the rope. After the second planetary reducer and the third planetary reducer further reduce the speed and transmit it to the winch drum 4, the winch drum 4 has enough torque to generate enough horsepower to pull the heavy objects. And due to the structural characteristics of the first planetary reducer, the second planetary reducer and the third planetary reducer themselves, they only occupy a very small lateral volume and can achieve the deceleration effect. At the same time, compared with the traditional parallel axis gear box, the planetary reducer is small in size and light in weight.

[0033] A support cylinder 19 is rotatably sleeved on the outer wall of the main shaft 3, both ends of the support cylinder 19 are fixedly connected to the support assembly 2, the third rotating shaft 40 is fixedly connected to the support cylinder 19, a bearing 39 is arranged around the outer wall of the support cylinder 19, and the inner wall of the capstan drum 4 is rotatably connected to the bearing 39. By providing the support cylinder 19, it can serve as an intermediate support component between the main shaft 3 and the capstan drum 4, so that the rotation between the two does not affect each other, and at the same time, the bearing 39 provides sufficient support force for the capstan drum 4.

[0034] The shift mechanism includes a connecting shaft 20, a shift shaft 21, a fourth inner gear ring 22, a first gear 23 and a shift cylinder 24. The shift shaft 21 is coaxially arranged at one end of the main shaft 3 facing the motor 5. The first gear 23 is rotatably sleeved on the end of the shift shaft 21 facing the motor 5. The fourth inner gear ring 22 is arranged on the shift shaft 21 at a side of the first gear 23 away from the motor 5. A support plate 25 is arranged on the side of the fourth inner gear ring 22 away from the motor 5. The support plate 25 is rotatably sleeved on the shift shaft 21. The shift cylinder 24 is sleeved on the shift shaft 21 between the fourth inner gear ring 22 and the first gear 23, and the shift cylinder 24 slides with the shift shaft 21 along its axial direction through a limiting groove 26. The first and second pawls 27 and 28 are respectively provided at both ends of the shift cylinder 24, and the first sockets 29 and the second sockets 30 cooperating with the first and second pawls 27 and 28 are respectively provided on the support plate 25 and the first gear 23; one end of the connecting shaft 20 is transmission-connected to the output shaft of the motor 5, and the other end is placed in the fourth inner gear ring 22, and a second gear 31 meshing with the fourth inner gear ring 22 is sleeved in the fourth inner gear ring 22, and a third gear 32 is sleeved on the outer wall of the connecting shaft 20, and the third gear 32 meshes with the first gear 23; the first sun gear 6 is fixedly mounted on the outer wall of the shift shaft 21 on the side of the fourth inner gear ring 22 away from the motor 5. With such arrangement, when the motor 5 is working, it will drive the second gear 31 and the third gear 32 to rotate, and then with the help of the meshing of the third gear 32 and the first gear 23, it can drive the first gear 23 to rotate. However, since the first gear 23 is no longer connected to the shift shaft 21 for rotation when the second pawl 28 is not inserted, it cannot drive the shift shaft 21 to rotate. When the second pawl 28 is inserted into the second socket 30, the first gear 23 is engaged with the shift shaft 21 with the help of the shift cylinder 24, thereby driving the shift shaft 21 to rotate. With the help of the rotation of the shift shaft 21, the first sun gear 6 will be driven to rotate, thereby performing subsequent deceleration. Similarly, when the first pawl 27 is inserted into the first socket 29, the support plate 25 will be connected to the shift shaft 21, thereby driving the fourth inner gear ring 22 to rotate with the help of the second gear 31, thereby driving the shift shaft 21 to rotate, and because the shift shaft 21 is driven by the second gear 31 and the shift shaft 21 is driven by the third gear 32, it is possible to drive the shift shaft 21 to rotate at different speeds and in different directions, thereby achieving different rotation directions and different rotation speeds of the capstan drum 4.

[0035] The shift mechanism further includes a shift fork 33, and a shift ring groove 34 is formed in a recessed manner around the outer wall of the shift cylinder 24. One end of the shift fork 33 is movably clamped in the shift ring groove 34 through a U-shaped fork 35. By arranging the shift fork 33 and the shift ring groove 34 to cooperate, the shift cylinder 24 can be driven to move along the shift shaft 21, so that the first pawl 27 or the second pawl 28 drives the shift shaft 21.

[0036] The limiting groove 26 is provided on the outer wall of the main shaft 3, a ball 36 is provided in the limiting groove 26 for rolling, and a rolling groove 37 for accommodating the ball 36 is provided at a recessed position on the inner wall of the shift cylinder 24. By providing the ball 36, the limiting groove 26 and the rolling groove 37, the shift cylinder 24 can move smoothly along the shift shaft 21 and will not rotate along the shift shaft 21.

[0037] A wire rack 38 is vertically arranged on the upper side of the base 1. By arranging the wire rack 38, a guiding effect can be played on the rope extending from the capstan drum 4.

[0038] Although the present invention is described herein with reference to a number of illustrative embodiments of the present invention, it will be appreciated that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the present disclosure, drawings, and claims, a variety of variations and modifications may be made to the components and / or layout of the subject combination layout.
