Description

Technical Field

[0001] This utility model relates to the field of recovery vehicle technology, specifically to an adjustment device for a recovery vehicle winch. Background Technology

[0002] During road rescue operations, tow trucks typically rely on winches mounted at the front or rear of the vehicle to retrieve and deploy steel cables or synthetic fiber ropes in order to tow, pull, or move disabled vehicles.

[0003] The existing winch structure mainly consists of a motor, a reducer, and a winding drum. During the winding process, the rope is directly wound around the surface of the drum. Due to the uneven force on the rope during traction operations, the rope entry direction is prone to deviation and the tension is uneven, resulting in the rope being misaligned on the drum. This further leads to problems such as rope skipping, rope tangling, or localized force concentration. Therefore, an adjustment device for the winch of a clearing vehicle is proposed. Summary of the Invention

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example

[0027] Please see Figures 1-4 The present invention provides a technical solution: an adjustment device for a winch of a clearing vehicle, comprising a clearing vehicle body 10 and a winch 20 fixedly installed on the clearing vehicle body 10;

[0028] The winch 20 is preferably a winding drum structure of steel wire rope or fiber rope, which can provide the winding and unwinding power required during vehicle towing and rescue.

[0029] A pressure equalization adjustment mechanism 30 is provided on one side of the clearing vehicle body 10. The pressure equalization adjustment mechanism 30 is arranged opposite to the winch 20 and is used to apply uniform pressure and guidance to the wound rope. The pressure equalization adjustment mechanism 30 includes a gantry support frame 31 fixed on the clearing vehicle body 10. The gantry support frame 31 adopts a rectangular frame structure, and its two ends are firmly connected to the base of the clearing vehicle body 10 by bolts to ensure stability under the high tension working state of the winch 20.

[0030] like Figure 3 As shown, a drive cylinder 32 is hinged to the middle of the gantry support frame 31. Specifically, the cylinder body end of the drive cylinder 32 is hinged to the gantry support frame 31 through a hinge seat 33, and the piston rod end of the drive cylinder 32 is hinged to the support beam 36 through another hinge seat 33. When the drive cylinder 32 is activated, its piston rod drives the support beam 36 to swing relative to the gantry support frame 31 around the first hinge seat 33, thereby changing the relative position between the pressure roller 38 and the rope, and realizing the adjustment of the rope's pressure.

[0031] like Figure 3 As shown, the two ends of the supporting beam 36 are respectively fixed with side support plates 35 by bolts. Bearing seats are provided on the inner sides of the two side support plates 35. An S-shaped fixing frame 37 is rotatably installed in each bearing seat. The S-shaped fixing frame 37 adopts a rotating structure. A rope pressing roller 38 is rotatably installed on its adjacent sides, thereby forming an S-shaped rope guide channel between the two rope pressing rollers 38.

[0032] In this embodiment, specifically: the rope passes over the top of the rope pressing roller 38 near the winch 20, and then crosses under the other rope pressing roller 38 to form a stable S-shaped path. Through this S-shaped guide channel, the rope is clamped and guided by the two rope pressing rollers 38 before it is wound into the winch 20, effectively avoiding rope tangling, skipping, or mutual shearing during the winding process.

[0033] In this embodiment, specifically: one end of at least one rope pressing roller 38 passes through the S-shaped fixing frame 37 and is coaxially connected to a stepper motor 39. The stepper motor 39 is installed on the outside of the S-shaped fixing frame 37 and can drive the corresponding S-shaped fixing frame 37 to rotate, thereby causing the rope pressing roller 38 to rotate, thus providing a driving and guiding effect when the rope passes through, reducing frictional resistance, and enhancing the stability of the rope's direction.

[0034] In this embodiment, specifically: the front side of the gantry support frame 31 is rotatably connected to a rotating rod 34 via a bearing seat. The two ends of the rotating rod 34 are respectively fixed through the side support plate 35, thereby fixing the side support plate 35 and the rotating rod 34 together and allowing the whole to rotate relative to the gantry support frame 31. This structure ensures overall stability while allowing the pressure equalization adjustment mechanism 30 to adapt to different force directions of the rope within a certain angle range.

[0035] In this embodiment, specifically: a controller 11 is provided on the gantry support frame 31, and the controller 11 is electrically connected to the drive cylinder 32 and the stepper motor 39; the operator can control the extension and retraction of the drive cylinder 32 and the start and stop of the stepper motor 39 through the controller 11, thereby realizing the synchronous adjustment of the pressing degree and guiding speed of the rope pressing roller 38.

[0036] In this embodiment, specifically, the pressure equalization mechanism 30 can be arranged on both sides of the winch 20 and symmetrically distributed to provide a more stable clamping and guiding effect under wide rope or heavy load conditions.

[0037] Working principle: When the clearing vehicle is performing rescue operations, the operator first starts the winch 20 on the clearing vehicle body 10 according to the needs of the site, so that its drum is in the working state of winding or releasing the rope.

[0038] Before the rope passes through the pressure equalization adjustment mechanism 30, the drive cylinder 32 operates under the control of the controller 11. Its piston rod drives the support beam 36 to swing relative to the gantry support frame 31, thereby adjusting the overall position of the side support plate 35 and the rope pressing roller 38. The function of this action is to adjust the degree of compression between the rope pressing roller 38 and the rope, so that the rope can maintain a stable direction under different tensions.

[0039] When the rope enters between the S-shaped fixing frames 37, it first passes above the rope pressing roller 38 on the side close to the winch 20, and then passes below the other rope pressing roller 38, forming an S-shaped guide path. Through this path, the two rope pressing rollers 38 clamp the rope, which not only ensures that the rope is tightly wound against the drum, but also effectively avoids rope jumping and tangling when the rope is quickly wound.

[0040] At the end of at least one rope pressing roller 38, a stepper motor 39 is provided and coaxially connected thereto. Under the control of the controller 11, the stepper motor 39 drives the rope pressing roller 38 to rotate, so that the rope pressing roller 38 can move synchronously with the rope, thereby reducing the frictional resistance between the rope and the rope pressing roller 38. Through this active guiding method, the rope can be kept straight, and the wear on the rope surface can be reduced, thus extending the service life of the rope.

[0041] A rotating rod 34 is provided on the front side of the gantry support frame 31. The two ends of the rotating rod 34 are fixedly connected to the side support plate 35, so that the entire side support plate 35 assembly can rotate around the rotating rod 34 relative to the gantry support frame 31. This structure provides additional angle adjustment capability for the clamping channel of the pressure roller 38, so that the pressure equalization adjustment mechanism 30 can better adapt to the rope stress at different angles and maintain a uniform pressing effect.

[0042] In actual operation, the operator only needs to issue instructions through the controller 11 to control the extension and retraction stroke of the drive cylinder 32 and the start and stop speed of the stepper motor 39 respectively. The drive cylinder 32 is responsible for adjusting the overall pressing angle and pressing degree, and the stepper motor 39 is responsible for the active guidance of the rope pressing roller 38. The two work together to ensure that the rope is evenly pressed and straightened before being wound into the winch 20.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
