DETAILED DESCRIPTION

[0024] Due to the limitations of the overall structural layout of the off-road vehicle, the winch rope guide device and the fixing device of the traction rope ring have limited design space and need to fully consider the ergonomics of the product when used. The hydraulic winch wire rope retracting and releasing rope has guiding defects, and the existing hydraulic winch device cannot meet the requirements.

[0025] In the existing hydraulic winch, there is still a problem that the traction rope ring moves left and right after the wire rope is reeled in, which makes it inconvenient to fix.

[0026] In order to solve the technical problem that the hydraulic winch wire rope has a guide defect, this embodiment discloses a hydraulic winch installation structure, please refer to Figure 2 The structure includes a beam body 100 and a rope guide assembly 200.

[0027] Please refer to Figure 2 The left and right sides of the cross beam body 100 are both provided with bolt holes 110. In terms of installation, the left and right sides of the cross beam body 100 are connected to the left and right longitudinal beams of the frame as a whole, specifically by bolt connection. Figure 2 As shown, the rear side of the cross beam body 100 is open, and a hydraulic winch installation space 120 is provided inside the cross beam body 100. The left side, right side, and rear side of the cross beam body 100 involved in this paragraph correspond to the left side, right side, and rear side of the vehicle frame.

[0028] Please refer to Figure 2 The rope guide assembly 200 is fixedly mounted on the beam body 100, and the rope guide assembly 200 is close to the rear side of the beam body 100. Figure 2 and Figure 3 The rope guide assembly 200 includes two rope guide mounting supports 210, two rope guide cylinders 220 and two pins 230. Among them, a pair of rope guide mounting supports 210 are mounted on the rear side of the crossbeam body 100, and the two rope guide mounting supports 210 are arranged opposite to each other on the left and right, and the axial ends of the pin 230 are respectively mounted on the two rope guide mounting supports 210, the two pins 230 are arranged in parallel at intervals, and the two rope guide cylinders 220 are respectively rotatably mounted on the outside of the two pins 230.

[0029] When the hydraulic winch is installed in the hydraulic winch installation space 120 inside the crossbeam body 100, the two rope guide installation supports 210 and the two rope guide drums 220 enclose a steel wire rope retracting and releasing space, and the steel wire rope of the hydraulic winch passes through the enclosed space when it is retracted and released. Since the rope guide drum 220 has a large left-right contact surface with the steel wire rope, it can adapt to the left-right movement of the steel wire rope retracting and releasing rope, solving the problem of guiding the steel wire rope retracting and releasing rope of the hydraulic winch.

[0030] When the steel wire rope is retracted or released, the rope guide drum 220 is driven to rotate. The service life of the pin shaft 230 is reduced by providing the rope guide drum 220 .

[0031] In this solution, the crossbeam body 100 and the rope guide assembly 200 installed with the hydraulic winch are designed to be detachable, and the crossbeam body 100 is connected to the left and right longitudinal beams of the frame as a whole, which has the characteristics of simple structure and good ergonomics, solves the problem of difficult spatial arrangement of the hydraulic winch, and solves the problem of insufficient bearing capacity of the hydraulic winch device under large loads.

[0032] In order to solve the problem that the traction rope ring moves left and right after the wire rope is collected, which may cause inconvenience in fixing, in some embodiments, the hydraulic winch mounting structure further includes a spring card 300, which is configured to be inserted into the traction rope ring of the hydraulic winch and then clamped on the two rope guide barrels 220. Based on the cylindrical shape of the rope guide barrel 220, in some embodiments, the spring card 300 is presented as follows Figure 2 The spring card 300 and the traction rope ring of the hydraulic winch are connected in a movable and detachable manner. Specifically, the spring card 300 is inserted into the traction rope ring when the spring card 300 is needed, and the spring card 300 is removed when the traction rope ring is working. When the hydraulic winch is in the storage state, the wire rope is recovered until the spring card 300 is as shown in FIG. Figure 2 The shown clamp is on the guide rope drum 220 and is further fixed by the tension of the traction rope.

[0033] The traction rope ring is fixed by a spring clamp 300, and the spring clamp 300 can be freely adjusted left and right on the rope guide drum 220, which solves the problem of the traction rope ring moving left and right after the hydraulic winch wire rope is reeled in, causing inconvenience in fixing.

[0034] In some embodiments, see Figure 3 The pin shaft 230 is equipped with a split pin 231, and the split pin 231 is passed through the pin shaft 230. After installation, the pin shaft 230 abuts against the rope guide mounting support 210 on one side, thereby preventing the pin shaft 230 from axial movement.

[0035] In some embodiments, see Figure 3 The pin 230 itself is provided with an outer ring protrusion 232 at one axial end and a radial shaft hole at a position close to the other axial end, and the pin 230 is passed through the radial shaft hole. Figure 3 and Figure 4 , Figure 4 The axial schematic diagram of the pin shaft 230 from the end where the outer ring protrusion 232 is located is shown, and the outer ring protrusion 232 is provided with a groove 2321 at the outer periphery.

[0036] Please refer to Figure 3 The outer ring protrusion 232 is equipped with a limit plate 240, and the limit plate 240 is installed on the rope guide mounting support 210 through bolts 241. Figure 3 , Figure 4 and Figure 5 The limiting plate 240 is inserted into the groove 2321 to prevent the pin shaft 230 from rotating freely.

[0037] In order to increase the service life of the pin 230 and the rope guide drum 220, in some embodiments, as Figure 3 As shown, a bushing 250 is installed between the rope guide drum 220 and the pin shaft 230 , and the bushing 250 can be a self-lubricating bushing 250 .

[0038] In some embodiments, please refer to Figure 2 and Figure 3 The rope guide mounting bracket 210 includes a vertical plate 211, a top plate 212 connected to the top of the vertical plate 211, and a bottom plate 213 connected to the bottom of the vertical plate 211. The vertical plate 211, the top plate 212, and the bottom plate 213 are all provided with bolt holes for bolting with the beam body 100. The rope guide mounting bracket 210 is connected to the beam body 100 by bolts, and specifically, can be bolted to the beam body 100 by the vertical plate 211, the top plate 212, and the bottom plate 213, thereby improving the connection strength.

[0039] This embodiment also provides a hydraulic winch device, including a hydraulic winch and the above-mentioned hydraulic winch mounting structure. The hydraulic winch is fixedly mounted in the hydraulic winch mounting space 120 of the crossbeam body 100 by bolts. The hydraulic winch device is mounted at the rear of the off-road vehicle.

[0040] In some embodiments, the hydraulic winch is installed in an embedded fixed manner, specifically, it is embedded and fixed in the hydraulic winch installation space 120 of the beam body 100 through a winch front installation bracket and a winch rear installation bracket.
