Concave center flat car reinforcing device

Abstract

The invention relates to a concave center flat car reinforcing device which comprises turnover type reinforcing ring assemblies and detachable reinforcing assemblies which are symmetrically installed at the bent corner portions of the two longitudinal ends of a concave center frame respectively, the turnover type reinforcing ring assembly comprises a ring base and a reinforcing ring, the ring base and the reinforcing ring are connected through a hinge, the ring base is installed on the concave center frame, the reinforcing rings and flexible reinforcing pieces are matched to longitudinally pull and reinforce the two ends of goods together without disassembly. The detachable reinforcing assembly comprises a reinforcing base and an upper backstop, the reinforcing base is connected with the upper backstop through a first fastener, and the detachable reinforcing assembly is used for reinforcing the upper portion of goods and can be disassembled and assembled according to loading requirements. The turnover type reinforcing ring assembly and the detachable reinforcing assembly can effectively solve the technical problem that an existing fixed type reinforcing ring and an existing fixed type reinforcing block which are arranged on the surfaces of the bent corner parts at the two longitudinal ends of the concave underframe in a protruding mode are prone to interference with long and large goods in the loading process, repeated use can be achieved, and the reinforcing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of flat cars with concave bottoms, in particular to a reinforcing device for flat cars with concave bottoms. Background technique [0002] The railway concave-bottomed flat car is the vehicle with the widest application range and the largest proportion of quantity and variety for transporting large goods. It is usually used to transport goods with moderate length, moderate height and wide width, such as transformers, generator stators, rolls, large machinery etc. During the transportation of these grown goods, they need to be reinforced longitudinally and transversely in accordance with the railway loading reinforcement requirements. The existing reinforcement method is to weld stoppers at the end and side of the cargo or use wire ropes to pull them. The existing reinforcements include reinforcement blocks, reinforcement plates and rope hooks welded on the concave bottom frame. There are many varieties and ...
