[0040] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0041] This embodiment provides a traction device 2 for use with a tractor 1, such as... Figure 1 , Figure 2 and Figure 3 As shown, the traction device 2 includes a traction unit 10 and a quick-release assembly 20. The traction unit 10 includes an integrated housing 11 and a drive member 111 (which may be a motor) and a winding member 112 (which may be a roller) mounted on the integrated housing 11. The drive member 111 drives the winding member 112 to rotate to wind up and unwind the traction rope on the winding member 112. The integrated housing 11 is provided with an integrated cavity 113, in which the winding member 112 is housed. The drive member 111 is located outside the integrated cavity 113. The integrated housing 11 is used to detachably connect the frame of the tractor 1 via the quick-release assembly 20.

[0042] In this embodiment, the drive component 111 of the traction unit 10 is housed within the integrated cavity 113 of the integrated housing 11. The integrated cavity 113 protects the drive component 111 from damage caused by external components. The winding component 112 is installed outside the integrated cavity 113 of the integrated housing 11, enabling integrated installation of the traction unit 10 and facilitating the disassembly and maintenance of the winding component 112. The drive component 111 drives the winding component 112 to rotate, thereby enabling the winding and unwinding of the traction rope on the winding component 112. When external equipment needs to be towed, the external equipment can be towed by winding the traction rope. This can be used for tractor self-rescue and for the rescue of external equipment, making the application scenarios of the traction device unrestricted. Furthermore, the traction unit 10 can be detachably installed on the frame of the tractor 1 via the quick-release assembly 20. By disassembling the integrated housing 11, the drive component 111 and the winding component 112 can be removed from the tractor, greatly improving the maintenance convenience of the traction device. In this embodiment, the traction unit 10 and quick-release assembly 20 work together to achieve external equipment traction while also facilitating maintenance. This allows the traction device to be applied to multiple usage scenarios and improves the ease of disassembly and assembly of the traction device.

[0043] The towing device 2 is a modular device that can be quickly installed when needed without altering the original vehicle structure. It simply requires connecting the quick-release component 20 to the tractor 1 frame using a quick-release mechanism such as a snap-fit. In this embodiment, the towing device 2 has a simple structure. By housing the drive component 111 within the integrated housing 11, the drive component 111 is protected, and the weight of the towing device 2 is reduced. Simultaneously, the drive component 111 drives the winding component 112 to rotate, thereby extending and retracting the towing rope to apply traction. This gives the towing device 2 both lightweight characteristics and strong traction, enabling efficient towing and extrication from difficult situations.

[0044] In some embodiments, the quick-release assembly 20 includes a horizontal bracket 21 and a vertical bracket 22. The traction unit 10 is connected to the horizontal bracket 21, and the first end of the horizontal bracket 21 is connected to the tractor 1 via a snap-fit ​​structure. The vertical bracket 22 is vertically arranged and connected to the second end of the horizontal bracket 21. The traction unit 10 is connected to the horizontal bracket 21, and the vertical bracket 22 is connected to the horizontal bracket 21. The vertical bracket 22 is positioned in front of the traction device 2, which can protect the traction device 2 from external impacts. In this embodiment, the traction device can be used to connect to the front end of the tractor 1's frame, the vertical bracket 22 is connected to the front end of the horizontal bracket 21, and the rear end of the horizontal bracket 21 is connected to the tractor 1's frame.

[0045] In some embodiments, the transverse support 21 includes a first transverse frame 211, a second transverse frame 212, a first connecting frame 213, and a mounting bracket 214. The first transverse frame 211, the second transverse frame 212, the first connecting frame 213, and the mounting bracket 214 can all be U-shaped frames with a U-shaped cross-section and integrally formed. The first ends of the first transverse frame 211 and the second transverse frame 212 are connected to the tractor 1, and the second ends of the first transverse frame 211 and the second transverse frame 212 are respectively connected to the two ends of the first connecting frame 213. The mounting bracket 214 is connected between the first transverse frame 211, the second transverse frame 212, and the first connecting frame 213, and is used to install the integrated housing 11. The transverse support 21 uses multiple U-shaped frames connected together, which avoids increasing weight by using sheet metal, achieving a lightweight design for the traction device 2. The supports can be connected by bolts or welding; this embodiment does not impose specific limitations.

[0046] In some embodiments, the vertical support 22 includes a first vertical frame 221, a second vertical frame 222, and a second connecting frame 223. The first ends of the first vertical frame 221 and the second vertical frame 222 are connected to the first connecting frame 213, and the second ends of the first vertical frame 221 and the second vertical frame 222 are respectively connected to the two ends of the second connecting frame 223. The first vertical frame 221, the second vertical frame 222, the second connecting frame 223, and the first connecting frame 213 form a hollow portion 24, through which the traction rope on the winding member 112 passes. Similarly, the vertical support 22 also adopts a support structure to avoid increasing the weight by using sheet metal. The first vertical frame 221, the second vertical frame 222, the second connecting frame 223, and the first connecting frame 213 form a hollow portion 24, further reducing the weight of the traction device 2. At the same time, the traction rope can pass through the hollow portion 24 to connect to external equipment.

[0047] In some embodiments, the quick-release assembly 20 further includes reinforcing rods 23 symmetrically arranged on both sides of the quick-release assembly 20; one reinforcing rod 23 has its two ends connected between the first horizontal frame 211 and the first vertical frame 221, respectively, and the other reinforcing rod 23 has its two ends connected between the second horizontal frame 212 and the second vertical frame 222, respectively. The front end of the reinforcing rod 23 is higher than its rear end, and the reinforcing rod 23 is inclined in the front-to-back direction, so that the reinforcing rod 23 forms a triangular stable structure between the horizontal frame and the vertical frame, which can enhance the stability between the horizontal frame and the vertical frame.

[0048] In some embodiments, the drive element 111 is connected to the side of the integrated housing 11 and passes through the side of the integrated housing 11 to connect with the winding element 112 inside the integrated cavity 113. The drive element 111 can be hydraulically driven or electrically driven. The drive element 111 is located outside the integrated housing 11 for easy control of starting or stopping the drive element 111 during use.

[0049] In some embodiments, the integrated shell 11 includes multiple side plates, which together form an integrated cavity 113 with an opening 114. Specifically, the multiple side plates are a left side plate, a top plate, a right side plate, a bottom plate, and a rear side plate. The left side plate, right side plate, top plate, bottom plate, and rear side plate together form an integrated cavity 113 that is closed on five sides and has an opening 114 on one side. When the integrated shell 11 is installed on the mounting bracket 214, the opening 114 faces the hollow part 24, and the traction rope passes through the opening 114 and the hollow part 24 in sequence to connect with external equipment.

[0050] In some embodiments, at least one guide member 115 is provided at the opening 114. The guide member 115 serves as a guide tube to guide the direction of the traction rope's release and retraction. In this embodiment, two guide members 115 are provided at the opening 114, respectively located on both sides of the opening 114. Providing guide members 115 at the opening 114 can prevent the rope from hard contacting and wearing with the opening 114. After the guide member 115 wears out, it can be directly removed and replaced from the opening 114 without opening the main body of the integrated shell 11.

[0051] In some embodiments, the top of the integrated housing 11 is provided with multiple lifting rings 116, which are spaced apart on the edge region of the top of the integrated housing 11. The lifting rings 116 are used for hooking by lifting equipment or manual lifting to transfer the traction unit 10. The spaced distribution of the lifting rings 116 on the edge region of the top of the integrated housing 11 ensures uniform force distribution when transferring the traction unit 10, thus avoiding damage to the traction unit 10.

[0052] like Figure 4 As shown, the second aspect of this utility model provides a tractor 1 connected to the aforementioned traction device 2, the traction device 2 being detachably connected to the front end of the tractor 1 frame to traction the tractor 1.

[0053] The traction device 2 of this invention connects to the tractor 1 via a quick-release assembly 20. The traction unit 10, in conjunction with a traction rope, pulls the tractor 1. The quick-release assembly 20 and the tractor 1 ensure a stable connection even in complex conditions such as muddy or soft ground. The traction device 2 has a simple and lightweight structure. The traction unit 10 applies continuous tension via the traction rope, and the direction of the traction rope can be adjusted during the pulling process to ensure that the direction of the tension always matches the trapped position of the tractor 1. This solution achieves a balance between efficient traction force transmission and reliable extrication, making it suitable for rapid rescue needs in situations where vehicles are stuck.
