As shown in the figure, the passenger car chassis protection device provided based on the purpose comprises a plurality of hoisting devices 1 arranged on a passenger car chassis, a protection plate 2 arranged on the hoisting devices 1 and a plurality of hydraulic telescopic rods 3 arranged on the chassis. And two ends of the hoisting device 1 are respectively connected with the passenger car chassis and the guard plate 2. The upper end of the hydraulic telescopic rod 3 is fixedly connected with the passenger car chassis. Hoisting device 1 hangs backplate 2 on the passenger train chassis, at ordinary times hydraulic telescoping rod 3 contracts to the intermediate position, and at this moment, hydraulic telescoping rod 3's lower extreme is gapped apart from the upper surface of backplate 2, and when backplate 2 contacts the object, backplate 2 moves up, then contacts with hydraulic telescoping rod 3, and hydraulic telescoping rod 3 restriction backplate 2 further shifts up, and then reaches the effect of protection passenger train chassis. When needing to maintain the vehicle tire or getting rid of poverty, 3 extensions of hydraulic telescoping rod, in order to make hoist device 1 can be tensile, hoist device 1 is the elastic material preparation, and backplate 2 moves down when hoist device 1 is tensile, and then bed hedgehopping vehicle, be convenient for dismouting tire or to the tire below filling material. Or alternatively, raise the vehicle to prevent the vehicle from flooding.

In order to protect as large an area as possible, the cover plate 2 covers a large part of the area of the passenger car chassis.

Because when changing the tire, generally only can change a tire, in order to reduce the consumption to the energy when the lifting vehicle, backplate 2 includes more than two branch backplate 21, and the size of dividing backplate 21 is the same basically, constitutes complete backplate 2 after all branch backplate 21 splice, and every branch backplate 21 all disposes a plurality of hoist device 1 and a plurality of hydraulic telescoping rod 3. In this way, the vehicle can be lifted locally each time only the apron plate 21 near the tire to be replaced needs to be moved.

In order to increase the whole elasticity of backplate 2 for backplate 2 is difficult damaged when colliding the object, and then increases backplate 2's life, divide backplate 21 to include the protection piece of a plurality of metal material preparation and the elasticity rope of connecting adjacent protection piece, the protection piece is the rectangle structure, and its border is equipped with a plurality of through-holes, and each protection piece is connected through the through-hole that passes adjacent protection piece to the elasticity rope.

As an embodiment, the hoisting device 1 is an elastic rope made of rubber material.
