Description

Technical Field

[0001] The present application relates to the field of road obstacle removal equipment, and in particular to a obstacle removal vehicle. Background Art

[0002] As an important rescue tool on the road, the tow truck is mainly used to remove vehicles that have accidents on the road. With the rapid development of my country's economy, there are more and more luxury cars on the road. When the road tow truck is working, it begins to pay great attention to the protection of accident vehicles. When some vehicles cannot rotate their wheels normally due to collision, the tow truck will cause wear or collision to the accident vehicle through the winch, resulting in secondary damage.

[0004] The present application provides a tow truck that adopts the following technical solution:

[0005] A tow truck, comprising:

[0006] Vehicle body;

[0007] A sub-frame, the end of which is hinged to the vehicle body, and the sub-frame is connected to the vehicle body through a first hydraulic cylinder;

[0008] A support plate is slidably mounted on the sub-frame, and the support plate is connected to the sub-frame via a second hydraulic cylinder; a cavity is provided in the support plate, and a plurality of through holes communicating with the cavity are provided on the upper surface of the support plate;

[0009] A baffle plate is vertically fixedly arranged at the end of the support plate adjacent to the front of the vehicle;

[0010] A winch mounted on the baffle;

[0011] A lifting mechanism, fixedly disposed in the cavity; and

[0012] A plurality of rollers are provided and rotatably arranged on the lifting mechanism, and the plurality of rollers correspond to the through holes one by one.

[0013] A further technical solution is that the lifting mechanism includes a motor fixedly arranged on the baffle and a screw rotatably arranged on the support plate, the screw passes through the baffle and is coaxially fixed to the output shaft of the motor, and a scissors-type lift is threadedly connected to the screw.

[0014] A further technical solution is that the lead screw is a bidirectional lead screw, and the lower end of the scissor lift is threadedly connected to the two ends of the lead screw respectively.

[0015] This application has the following beneficial technical effects:

[0016] When the wheels of a faulty vehicle cannot turn, the scissor lift can be upgraded by rotating the motor so that the roller protrudes into the through hole. The damaged vehicle can then move to the pallet following the rotation of the roller, reducing secondary collision and wear on the specific faulty vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0021] The present application embodiment discloses a tow truck. Figure 1 and Figure 2 A tow truck includes a vehicle body 1; a sub-frame 2, the end of which is hinged on the vehicle body 1, and the sub-frame 2 is connected to the vehicle body 1 through a first hydraulic cylinder 11; a support plate 3, which is slidably mounted on the sub-frame 2, and the support plate 3 is connected to the sub-frame 2 through a second hydraulic cylinder 21; a cavity 31 is provided in the support plate 3, and a plurality of through holes 32 connected to the cavity 31 are opened on the upper end surface of the support plate 3; a baffle 4, which is vertically fixedly arranged at the end of the support plate 3 near the front of the vehicle; a winch 41, which is installed on the baffle 4; a lifting mechanism, which is fixedly arranged in the cavity 31; and a plurality of rollers 33, which are provided and rotatably arranged on the lifting mechanism, and the plurality of rollers 33 correspond to the through holes 32 one by one.

[0022] The first hydraulic cylinder 11 is used to control the lifting angle of the sub-frame 2, and the second hydraulic cylinder 21 can control the pallet 3 to move along the sub-frame 2 after the sub-frame 2 is lifted, until the rear end of the pallet 3 abuts against the ground. The pallet 3 is used to support the faulty vehicle, and the winch 41 pulls the faulty vehicle onto the inclined pallet 3, and then the first cylinder and the second cylinder act simultaneously to reset the sub-frame 2 and the pallet 3, so that the faulty vehicle can be loaded onto the tow truck.

[0023] The lifting mechanism includes a motor 51 fixedly arranged on the baffle 4 and a lead screw 52 rotatably arranged on the support plate 3. The lead screw 52 penetrates the baffle 4 and is coaxially fixed to the output shaft of the motor 51. A scissor-type lift 53 is threadedly connected to the lead screw 52.

[0024] When the wheels of the faulty vehicle cannot rotate, the motor 51 can be rotated to upgrade the scissor lift 53, so that the roller 33 protrudes to the through hole 32, and the damaged vehicle can follow the rotation of the roller 33 and move to the support plate 3. In addition, when the roller 33 protrudes from the through hole 32, other obstacles such as boulders and trees blocking the road can also be cleared, which has a high use effect.

[0025] Furthermore, the lead screw 52 is a bidirectional lead screw, and the lower end of the scissor lift 53 is respectively threadedly connected to the two ends of the lead screw 52. When the motor 51 rotates, the two ends of the scissor lift 53 connected to the lead screw 52 can move toward or away from each other at the same time, so that the roller 33 can be controlled to move upward or downward facing the through hole 32, reducing the phenomenon of inaccurate position of the roller 33 caused by deviation.

[0026] A support rod 54 for supporting the scissor-type lift 53 is hinged in the cavity 31 , and is located near both ends of the cavity 31 , so as to prevent the roller 33 from being unevenly stressed and causing the scissor-type lift 53 to tilt and sink.

[0027] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
