The working process of the wrecker 1 is as follows:

1. Drive the wrecker 1 to the left side of the faulty vehicle, and ensure that the two front and rear fork tine 28 mechanisms are aligned with the front and rear wheels of the faulty vehicle, respectively. At this time, the relative positions of the components of the wrecker 1 are shown in Figure 6;

2. The driving cylinder of the vertical moving mechanism 8 contracts, the moving frame 26 descends under the action of gravity, and the fork 28 mechanism also descends until the fork 28 on it is slightly higher than the ground; Under the action, it stretches out and engages the four wheels of the faulty vehicle; at this time, the relative positions of the components of the wrecker 1 are shown in Figure 7, and the faulty vehicle is located above the fork 28 mechanism.

3. The hydraulic outrigger mechanism is activated, and the hydraulic outrigger extends to the ground to provide support for the wrecker 1.

4. The driving oil cylinder of the vertical moving mechanism 8 is extended, the fifth steel cable 27 pulls the moving frame 26 to move upward, the faulty vehicle falls on the fork 28, and moves up with the moving frame 26 to the top of the stroke. At this time, the fork 28 is slightly It is higher than the horizontal moving mechanism 3; at this time, the relative positions of the components of the wrecker 1 are shown in Figure 8.

5. The driving oil cylinder on the horizontal moving mechanism 3 is extended, the first steel cable 16 and the second steel cable 17 pull the moving trolley 5 to the left to move to the top of the stroke, and the vertical moving mechanism 8 and the faulty vehicle also move to the left. At this time, the faulty vehicle falls on the wrecker truck 1, and the loading of the faulty vehicle is completed; at this time, the relative positions of the components of the wrecker truck 1 are shown in Figure 8.

6. The hydraulic outriggers are retracted to complete the clearance work.

In summary, the overall structure layout is reasonable, and can effectively improve the removal of faulty vehicles, saving time and effort. Therefore, the wrecker 1 can complete the wrecker work of the faulty vehicle within two minutes, greatly improving the efficiency of wrecker work; in addition, the two horizontal moving mechanisms 3 can reduce the first drive without increasing the cost. The length of the drive is 6, which improves the problem of interference between various components caused by the excessive length of the existing drive.

The above descriptions are only preferred embodiments of the present application, and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
