The primary function of the liner assembly 30 is to insulate and prevent freezing. The first layer of foam plate has low heat conductivity coefficient, basically does not conduct heat, and therefore, the temperature in the loading space cannot be too low due to the low temperature at the outer side of the open wagon. The second layer of plywood has two characteristics, one is that the second layer of plywood has certain compressive property, can not destroy the lining structure because of loading and unloading goods, and the other is that it can not freeze together with goods because of low temperature easily because of the peculiar performance of timber itself. The lining assembly is welded to the floor and the end side walls of the vehicle body by bolts. The welding mode does not need to drill holes on the vehicle body, and the structural strength of the floor, the end wall and the side wall cannot be influenced.

Compared with the prior art, the lining assembly of the embodiment can solve the problem that goods in low-temperature areas are frozen or adhered.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:

because the lining assembly is arranged on the inner wall surface of the vehicle body and the upper surface of the floor, when the open wagon transports goods in a low-temperature cold environment, the lining assembly can separate the goods from the inner wall surface of the floor and the vehicle body, so that the goods are effectively prevented from being adhered to the floor or the inner wall surface of the vehicle body, the dead weight of the open wagon cannot be increased due to the adhesion of the goods after the open wagon is unloaded, and the transportation cost is reduced.
