Buffer connection device for vehicle and application of buffer connection device

Abstract

The invention discloses a buffer connection device for a vehicle and application of the buffer connection device. The device comprises a connection rod, wherein one end of the connection rod is arranged in a vehicle roof in a sleeving manner; a guiding frame body connected with a vehicle end plate to form an integrated structure is arranged on the connection rod in a sleeving manner; the other end of the connection rod is connected with a buffer stop; when the buffer stop is stressed, the connection rod is pushed and slides relative to the guiding frame body; an elastic piece is sleeved at a position, which is located between the vehicle roof and the guiding frame body, outside the connection rod. According to the buffer connection device for the vehicle, the connection rod is connected with the buffer stop, so that soft connection is realized, and protection of a vehicle structure is facilitated; when arranged between the vehicle end plate and the vehicle roof, the connection device disclosed by the invention is simple in structure; the connection rod can slide between the vehicle end plate and the vehicle roof, so that energy can be buffered, and reliable connection can be realized.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a vehicle buffer connection device and its application. Background technique [0002] The existing industrial and mining vehicle buffer device is separated from the connecting device, and the buffer cake and the connecting device are independent. This device takes up a large installation space and has high requirements on the structural strength of the vehicle end. [0003] In addition, the transportation vehicles in the line or the vehicles in the industrial and mining industries often use hard connections, which seriously damage the connecting parts when the vehicles are connected; or, only the bolts are used for simple connection, which leads to the occurrence of sports car accidents and affects the safety of factory operations. Contents of the invention [0004] The first object of the present invention is to provide a buffer connection device for vehicles, which has a simple ...
