Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, the present invention provides a technical solution:

a chassis lifting appliance for a special vehicle comprises a base 1, wherein wedge-shaped plates 3 are fixed on two sides of the base 1, and a plurality of anti-skidding raised lines 12 are arranged on the upper surfaces of the two wedge-shaped plates 3 to prevent the special vehicle from sliding; four first electric telescopic columns 4 are fixedly mounted on the inner bottom wall of the base 1, the top of each first electric telescopic column 4 extends to the outside of the base through a through hole formed in the upper surface of the base 1, a supporting plate 6 is fixed at the top end of each first electric telescopic column 4, a first anti-skid pad 5 is arranged on the upper surface of each supporting plate 6, second electric telescopic columns 2 are hinged to four corners of the base 1, each first electric telescopic column 4 and each second electric telescopic column 2 are electrically connected with an external master controller, and the master controller is electrically connected with a 220V mains supply; a first pressing plate 7 is fixed at the top end of each second electric telescopic column 2, a second anti-skid pad 11 is arranged on the lower surface of each first pressing plate 7, and the first anti-skid pad 5 and the second anti-skid pad 11 are made of rubber materials, so that the surface of a vehicle is prevented from being damaged; the upper surface of each first pressing plate 7 is fixed with a connecting piece 8, and each connecting piece 8 is a clip-shaped connecting piece and is used for connecting a lifting rope; the top of each connecting piece 8 is connected with a fixing bolt 9 through threads, and the bottom end of each fixing bolt 9 is fixed with a second pressing plate 10.
