[0031] like Figure 3 As shown, the output shaft 10 is coaxially arranged with the planetary gear transmission 4 and the hoisting drum 3, and the output shaft 10 is connected to the transmission shaft 12 passing through the hoisting drum 3, and the transmission shaft 12 is further extended to the input end 7 and connected to the input end 7, and the output end 8 is connected to the hoisting drum 3. Of course, other structures are also possible, for example, the output shaft 10 passes through the hoisting drum 3 and then extends to the input end 7 and is connected to the input end 7.

[0032] The power unit 11 drives the winch drum 3 to rotate through the output end 8 after the speed is changed at both sides of the gearbox 5 and the planetary gearbox 4.

[0033] In some embodiments, Figure 1 As shown, the gearbox 5 includes a first operating part 13, a forward gear position and a reverse gear position. The first operating part 13 can switch the gearbox 5 between the forward gear position and the reverse gear position.

[0034] In some embodiments, Figures 1 to 5As shown, the gearbox 5 includes a housing 5.1, in which an input shaft 9, an output shaft 10, a shift shaft 14, a reversing shaft 15, a shift fork shaft 16 and a shift fork 17 are installed, the first operating part 13 is connected to the shift fork 17, the input shaft 9 is provided with a first gear 18 and a second gear 19 which are coaxially arranged and connected together, the shift fork 17 is slidably fitted on the shift fork shaft 16, the shift fork 17 is used to shift the first gear 18 and the second gear 19 to move axially together, the output shaft 10 is provided with a third gear 21, and the shift shaft 14 is provided with a fourth gear 22 , the reversing shaft 15 is provided with a fifth gear 23 and a sixth gear 24, the third gear 21, the fourth gear 22, and the fifth gear 23 are meshed in sequence, the first gear 18 and the second gear 19 are located between the fifth gear 23 and the sixth gear 24, when in the forward gear, the first gear 18 and the second gear 19 move to the side of the fourth gear 22 and the first gear 18 meshes with the fourth gear 22, when in the reverse gear, the first gear 18 and the second gear 19 move to the side of the sixth gear 24 and the second gear 19 meshes with the sixth gear 24, when in neutral, the first gear 18 and the second gear 19 move between the fifth gear 23 and the sixth gear 24. In this way, on the one hand, it is possible to switch between the forward gear, the reverse gear and the neutral gear, and on the other hand, the pure mechanical structure based on gears has a strong load capacity and is stable and reliable.

[0035] Further, such as Figure 5 As shown, the shift shaft 14 is further provided with a seventh gear 25, and the seventh gear 25 has a different number of teeth from the fourth gear 22. The fourth gear 22 provides a first gear, and the seventh gear 25 provides a second gear. When the first gear is used, the first gear 18 is meshed with the fourth gear 22, and when the second gear is used, the second gear 19 is meshed with the seventh gear 25. In this way, different rotation speeds can be generated by changing the first gear and the second gear, so that the rotation speeds of the winch drum 3 are different.

[0036] In some embodiments, Figure 3 , 6As shown, the first clutch 6 includes an axial push portion 26, a first coupling portion 27 and a second coupling portion 28. The axial push portion 26 is sleeved on the input shaft 9, the first coupling portion 27 is connected to the input shaft 9, the first coupling portion 27 and the second coupling portion 28 can be axially separated and sleeved, the first coupling portion 27 is provided with an outer conical surface 29, and the second coupling portion 28 is provided with an inner conical surface 30. The axial push portion 26 pushes the first coupling portion 27 to move axially so that the outer conical surface 29 and the inner conical surface 30 are sleeved and driven, and the sleeve drive generates a self-locking friction force. In this way, not only is the structure simple and reliable, but the sleeve drive of the outer conical surface 29 and the inner conical surface 30 realizes a hard connection drive, thereby making the transmission efficiency high. At the same time, the cone surface is set so that the sleeve drive generates a self-locking friction force, that is, self-locking is provided and the self-locking adopts a purely mechanical structure, thereby providing high reliability and being less affected by the environment.

[0037] In some embodiments, Figure 5 , 6 As shown, the axial pushing portion 26 includes a first portion 31 and a second portion 32, the first portion 31 and the second portion 32 are threadedly connected, the first portion 31 is rotatably sleeved with the input shaft 9 and the first portion 31 is fixed on the end cover 5.2 of the housing 5.1, and the second portion 32 is connected with a second operating portion 33, the second operating portion 33 can make the second portion 32 rotate relative to the first portion 31, and the rotation makes the second portion 32 axially move relative to the first portion 31 through the threaded connection, and the axial movement is used to push the first coupling portion 27 to move axially so that the outer conical surface 29 and the inner conical surface 30 are sleeved for transmission. In this way, the outer conical surface 29 and the inner conical surface 30 are reliably combined by using the threaded connection of the first portion 31 and the second portion 32, and are not easy to separate when self-locking, thereby improving reliability.

[0038] Further, such as Figure 5 , 6 As shown, the second operating part 33 includes a ring part 34 sleeved with the second part 32, and the ring surface 35 of the ring part 34 is arranged adjacent to the end surface 36 of the first combination part 27. When the second operating part 33 drives the second part 32 to move axially, the ring surface 35 abuts against the end surface 36 of the first combination part 27 to push the first combination part 27 to move axially. The second part 32 is provided with a convex ring 37, which is movably sleeved with the first combination part 27. A retaining ring 38 is arranged at the end surface 36 of the first combination part 27. The convex ring 37 cooperates with the retaining ring 38. When the second operating part 33 drives the second part 32 to move axially back, the convex ring 37 drives the first combination part 27 to move axially back through the retaining ring 38 so that the first combination part 27 and the second combination part 28 are mutually released. In this way, a purely mechanical structure is adopted, thereby providing high reliability and being less affected by the environment.

[0039] In some embodiments, Figure 6As shown, a plurality of positioning holes 39 are provided on the circumference of the second part 32, and the second operating part 33 includes a ring part 34 sleeved with the second part 32, and the ring part 34 is provided with a positioning column 40, and the positioning column 40 is connected with different positioning holes 39 to adjust the circumferential position of the second operating part 33 relative to the second part 32. In this way, the user can adjust the circumferential position of the second operating part 33 relative to the second part 32 according to the comfort of operation, which is mainly based on users of different heights, and provides the aforementioned adjustment function.

[0040] In some embodiments, Figure 2 , 3 As shown, the planetary gear transmission 4 is provided with a second clutch 41. The second clutch 41 realizes clutching by pushing the clutch gear ring 4.1 to different positions. Specifically, when the clutch gear ring 4.1 is pushed to a fixed position, the clutch gear ring 4.1 will remain stationary, so that the planetary gear can be driven based on the clutch gear ring 4.1. On the contrary, when the clutch gear ring 4.1 is pushed to a rotatable position, the clutch gear ring 4.1 will rotate, and then the rotation of the planetary gear will be idle and unable to be driven, thereby achieving the purpose of clutching.

[0041] By setting the first clutch 6 and the second clutch 41, on the one hand, the user has a variety of options for clutch control, which is conducive to selecting use according to different application scenarios. On the other hand, when the second clutch 41 is released, the winch drum 3 can be pulled more easily, which is conducive to releasing the traction rope wound on the winch drum 3.

[0042] In some embodiments, Figure 1 As shown, it also includes a frame base 42, and the first support 1, the second support 2, and the power unit 11 are installed on the same frame base 42. In this way, on the one hand, the transmission is more reliable and stable, and on the other hand, the overall movement is convenient, and there is no need to reconnect after the movement.

[0043] In addition, the frame-type base 42 is beneficial for reducing weight, while also being able to provide higher supporting strength and anti-deformation capability.

[0044] In some embodiments, Figure 1 As shown, a protective cover 43 is also included, and the protective cover 43 is installed at the first clutch 6. Thereby protecting the first clutch 6, and also protecting personnel from being hurt by the first clutch 6.

[0045] From the above, it can be seen that the winch disclosed in the present invention has a main body designed with a purely mechanical structure, has strong environmental adaptability, large traction force, and high reliability. If a diesel engine, gasoline engine, etc. with strong environmental adaptability is used, no electricity supply is required, and it can be widely used in different field environments.

[0046] When understanding the present invention, if necessary, the above structure can refer to other embodiments / attached Figure 1 And understand, no further elaboration here.

[0047] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be thought of by any person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
