The bottom end of the second support rod 5 is provided with a rotatable wheel 4. When the electric telescopic rod 2 is retracted, the second support rod 5 is subjected to the tension and rotates counterclockwise with the second pin shaft 7 as the axis to realize the automatic descent of the rescue platform 1. Among them, several electric telescopic rods 2 are controlled by the same controller to realize synchronous control, such as Figure 4 As shown, the bottom end of the second support rod 5 can be designed to be inclined, which provides convenience for lifting the wheel 4.

[0030] At least one mounting frame 10 is disposed on the rescue platform 1 , and two ends of the mounting frame 10 are respectively connected to two limiting sleeves 12 in a corresponding group.

[0031] In the specific implementation process, Figure 1 and Figure 2 As shown, the first support rod 3 is parallel to the rescue platform 1, and the second support rod 5 is designed in a Y-shaped structure. Through its design, it can ensure that when the electric telescopic rod 2 is telescoped or extended, the second support rod 5 is forced to rotate, and a large rotation range is formed to realize the lifting and lowering of the rescue platform 1.

[0032] In the specific implementation process, Figure 1 As shown, a traction plate 8 with a triangular structure design is fixedly installed at the front end of the rescue platform 1, and a guide tail plate 9 is fixedly installed at the rear end of the rescue platform 1, and the guide tail plate 9 is a wedge-shaped structure design. Through its design, the rescue platform 1 is easy to be installed on the trailer, and at the same time, the guide tail plate 9 can fit the ground when the rescue platform 1 is lowered, and its slope is used to facilitate moving the rescued vehicle to the rescue platform 1.

[0033] In the specific implementation process, Figure 1 and Figure 3 As shown, the mounting frame 10 is designed as a U-shaped structure, and a plurality of hooks 11 are provided on the mounting frame 10. Through its design, it is convenient to use the mounting frame 10 to protect the rescued vehicle, and it is also convenient to bind the vehicle and hang and carry some items.

[0034] In the specific implementation process, Figure 3As shown, the outer walls at both ends of the mounting frame 10 are provided with a plurality of positioning holes 14, and the two ends of the mounting frame 10 are respectively clamped in two limiting sleeves 12, and the limiting sleeves 12 are provided with fastening screws 13 that can be selectively connected to the plurality of positioning holes 14.

[0038] The working principle of the towing device for rescue provided by the utility model is as follows: when rescuing a vehicle, the electric telescopic rod 2 is started to work and contract, so that the second support rod 5 is subjected to the pulling force and rotates counterclockwise with the second pin shaft 7 as the axis. At this time, the wheel is lifted and the wheel is not in contact with the ground, and the rescue platform 1 forms a relative displacement and automatically descends until its bottom touches the ground. Figure 5 Then, the rescue vehicle is towed to the rescue platform 1 through the guide tail plate 9. After the vehicle is placed on the rescue platform, the electric telescopic rod 2 is started to work and extend, which can push the second support rod 5 to rotate clockwise around the second pin shaft 7. The wheels are in contact with the ground, and the rescue platform 1 is supported by the second support rod to rise to a certain height. Figure 3 , and the device is connected to the trailer by the traction plate 8, so that the rescue vehicle can be towed away for rescue. Such operation is adopted in the towing and carrying of boats, fire fighting equipment or other large items.
