[0002] An off-road vehicle is a vehicle specially designed for off-road driving. It mainly refers to off-road vehicles that can be used on rugged terrain. Its main features are a non-load-bearing body, four-wheel drive, a higher chassis, tires with better grip, a higher exhaust pipe, greater horsepower, and thick and strong bumpers. Off-road vehicles can not only adapt to various road conditions in the wild, but also give people a sense of ruggedness and heroism. In cities, many people also like to drive off-road vehicles. Off-road vehicles are members of the military vehicle family, and most of them have certain off-road driving capabilities.

[0003] In the existing technology, off-road vehicles are often driven outdoors, and are therefore prone to complex road conditions such as sand pits, mud pits, and snow, which can cause the off-road vehicles to get stuck and unable to move. The hydraulic winch can provide stable traction to help the vehicle get out of trouble. The hydraulic winch mainly converts energy into rope tension through an electric motor and a hydraulic pump, and achieves the effect of towing the off-road vehicle by winding the rope. However, when the hydraulic winch fails and cannot rotate, the rope cannot be retracted and released, which in turn makes it impossible to reel in the rope, which can easily cause the rope to become tangled and wear in contact with the ground. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, when the hydraulic winch fails and cannot rotate, the rope cannot be retracted or released, which in turn makes it impossible to reel the rope, which easily causes the rope to become tangled and wear in contact with the ground. The utility model proposes a hydraulically driven rescue winch for off-road vehicles.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a hydraulically driven rescue winch for off-road vehicles, comprising a hydraulic winch, the surface of which is provided with a winding mechanism;

[0006] The winding mechanism includes a winding drum, the inner cavity of the winding drum is rotatably connected to the surface of the hydraulic winch, the surface of the hydraulic winch is provided with a first hollow groove, the inner cavity of the first hollow groove is rotatably connected to a worm, the inner cavity of the hydraulic winch is provided with a second hollow groove, the inner cavity of the second hollow groove is rotatably connected to a worm wheel, one side of the worm wheel is fixedly connected to a gear, the inner cavity of the hydraulic winch is provided with a third hollow groove, the inner cavity of the third hollow groove is slidably connected to a rack, the teeth of the rack and the teeth of the gear are engaged with each other, the inner cavity of the winding drum is provided with a card slot, and the rack is slidably connected to the inner cavity of the card slot.

[0007] Preferably, a mounting groove is provided on the surface of the winding drum, and a ball is rotatably connected to the inner cavity of the mounting groove.

[0008] Preferably, a second magnet block is fixedly connected to the inner cavity of the slot, a first magnet block is provided at the bottom of the second magnet block, and the bottom of the first magnet block is fixedly connected to the top of the rack.

[0009] Preferably, a fixing rod is fixedly connected to the surface of the winding drum, and a plurality of fixing rods are provided.

[0010] Preferably, a baffle is provided on one side of the fixing rod, and the inner cavity of the baffle is fixedly connected to the surface of the winding drum.

[0011] Preferably, a fourth hollow groove is provided in the inner cavity of the hydraulic winch, the inner cavity of the fourth hollow groove is rotatably connected to a limit block, and one side of the limit block is fixedly connected to one side of the gear.

[0012] Preferably, a handle is fixedly connected to one side of the worm, and the handle is S-shaped.

[0013] The utility model is beneficial in that:

[0014] The utility model connects the rope of the hydraulic winch to the surface of the winding drum, and then rotates the worm to drive the gear to rotate through the worm gear.

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1-5 To further explain this application,

[0024] The present application discloses a hydraulically driven rescue winch for off-road vehicles. Figure 1-4 A hydraulically driven rescue winch for off-road vehicles includes a hydraulic winch 1. A winding mechanism 2 is provided on the surface of the hydraulic winch 1. The hydraulic winch 1 can retract and release the rope, thereby achieving the effect of towing the off-road vehicle.

[0025] The winding mechanism 2 includes a winding drum 201, the inner cavity of the winding drum 201 is rotatably connected to the surface of the hydraulic winch 1, the surface of the hydraulic winch 1 is provided with a first hollow groove 202, the inner cavity of the first hollow groove 202 is rotatably connected to a worm 204, the inner cavity of the hydraulic winch 1 is provided with a second hollow groove 206, the inner cavity of the second hollow groove 206 is rotatably connected to a worm gear 205, one side of the worm gear 205 is fixedly connected to a gear 207, the inner cavity of the hydraulic winch 1 is provided with a third hollow groove 208, the inner cavity of the third hollow groove 208 is slidably connected to a rack 209, the teeth of the rack 209 and the teeth of the gear 207 are meshed with each other, the inner cavity of the winding drum 201 is provided with a card slot 210, and the rack 209 is slidably connected to the inner cavity of the card slot 210;

[0026] The winding drum 201 is sleeved on the outside of the hydraulic winch 1 and can replace the hydraulic winch 1 to wind up the rope. The worm 204 can be placed inside the first hollow groove 202, and it is convenient for people to rotate the worm 204. The worm wheel 205 can be placed inside the second hollow groove 206, so that the worm wheel 205 can be located on the upper side of the worm 204 and meshed with the worm 204, which makes it possible for the worm 204 to drive the worm wheel 205 to rotate when it rotates. The second hollow groove 206 is connected to one side of the worm wheel 205 and can be driven by the worm wheel 205 to rotate. The rack 209 can be placed inside the third hollow groove 208, and the rack 209 is meshed with the gear 207, which makes it possible for the gear 207 to drive the rack 209 to move up and down when it rotates, and then the rack 209 can be moved into the gear 207 through the slot 210. The hydraulic winch 1 is in the slot 210, thereby achieving the effect of connecting the hydraulic winch 1 and the winding drum 201. This allows the hydraulic winch 1 to drive the winding mechanism 2 to rotate at the same time when winding the rope, and to reel in and release the rope through the winding mechanism 2. When the hydraulic winch 1 is damaged and cannot rotate to reel in the rope, it is only necessary to rotate the worm 204 to drive the rack 209 to move out of the slot 210 through the worm wheel 205 and the gear 207, and then the winding drum 201 can be rotated alone to achieve the winding of the rope. The hydraulic winch 1 will not be damaged and the rope cannot be reeled, which will cause the rope to easily become knotted and wear in contact with the ground. The meshing connection between the worm 204 and the worm wheel 205 also has a certain self-locking property, which makes the gear 207 not easy to rotate, and the rack 209 is also not easy to move out of the slot 210.

[0027] Reference Figure 5 A mounting groove 3 is provided on the surface of the winding drum 201, and a ball 4 is rotatably connected to the inner cavity of the mounting groove 3. The interior of the mounting groove 3 can be used to install the ball 4, and the ball 4 can reduce the rotational friction of the winding drum 201 when the winding drum 201 rotates on the surface of the hydraulic winch 1, thereby making the rotation of the winding drum 201 smoother and more labor-saving.

[0028] Reference Figure 4The inner cavity of the slot 210 is fixedly connected to the second magnet block 6, and the bottom of the second magnet block 6 is provided with the first magnet block 5. The bottom of the first magnet block 5 is fixedly connected to the top of the rack 209. The first magnet block 5 and the second magnet block 6 can be magnetically adsorbed together, which can improve the stability of the rack 209 inside the slot 210 and make it less likely to detach from the slot 210.

[0029] Reference Figure 2 The surface of the winding drum 201 is fixedly connected with a fixing rod 7, and a plurality of fixing rods 7 are provided. The fixing rod 7 can make it more convenient for people to manually rotate the winding drum 201. Only the fixing rod 7 needs to be turned to drive the winding drum 201 to rotate, and multiple fixing rods 7 can make the rotation effect of the winding drum 201 better.

[0030] Reference Figure 2 A baffle 8 is provided on one side of the fixed rod 7. The inner cavity of the baffle 8 is fixedly connected to the surface of the winding drum 201. The baffle 8 can block the fixed rod 7, which makes it difficult for the winding drum 201 to touch the fixed rod 7 when the rope is wound, so that the fixed rod 7 is not easy to be deformed and broken.

[0031] Reference Figure 3 The inner cavity of the hydraulic winch 1 is provided with a fourth hollow groove 9, and the inner cavity of the fourth hollow groove 9 is rotatably connected to a limiting block 10. One side of the limiting block 10 is fixedly connected to one side of the gear 207. The limiting block 10 can be placed inside the fourth hollow groove 9, and the limiting block 10 can be used to limit the gear 207 and the worm gear 205, so that the gear 207 and the worm gear 205 are not easy to move, but can be stably in place and rotate smoothly.

[0032] Reference Figure 1 A handle 11 is fixedly connected to one side of the worm 204 . The handle 11 is S-shaped. The S-shaped handle 11 can make it more labor-saving and convenient for people to rotate the worm 204 .

[0033] Working principle: When using this device, first connect the rope of the hydraulic winch 1 to the surface of the winding drum 201, then rotate the worm 204 to drive the worm wheel 205 to rotate, the worm wheel 205 will drive the gear 207 to rotate together, and the gear 207 will drive the rack 209 to move into the inside of the card slot 210, so as to achieve the effect of connecting the hydraulic winch 1 and the winding drum 201. At this time, the hydraulic winch 1 can drive the winding drum 201 to rotate to retract and release the rope. When the hydraulic winch 1 is damaged and cannot rotate to rewind the rope, the worm 204 can be rotated in the reverse direction to drive the worm wheel 205 to reverse together, and the worm wheel 205 The gear 207 will drive the rack 209 to move in the opposite direction, so that the rack 209 can move out of the inside of the card slot 210, thereby achieving the effect of separating the hydraulic winch 1 and the winding drum 201. At this time, the winding drum 201 can be rotated alone to realize the winding of the rope. The hydraulic winch 1 will not be damaged and the rope cannot be wound, which will cause the rope to easily get knotted and wear in contact with the ground. This can solve the problem that when the hydraulic winch 1 fails and cannot rotate, the rope cannot be wound and released, which in turn makes it impossible to wind the rope, which easily causes the rope to get knotted and wear in contact with the ground.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
