Embodiment Construction

[0008] Referring to the accompanying drawings, the embodiments of the present invention will be described in detail. The frame mounting seat (1) adopts a right-angle structure with triangular ties, and is fixed on the frame of the vehicle bogie by bolts. The bracket (2) adopts a round steel pipe structure with sufficient rigidity and strength, and its upper end is fixed on the frame mounting seat (1). The front and rear pressing plates (6) and (8) adopt a profiled structure. The rear pressing plate (8) is fixed on the lower end of the support (2) by installing the adjusting bolt (3). The upper half of every rubber braided hose (7) is inserted with cork (4). The bolt (5) clamps the upper half of the rubber braided hose (7) between the front and rear pressure plates (6) and (8).

Abstract

The invention discloses an elastic barrier eliminating device for a railway vehicle. The elastic barrier eliminating device comprises a framework installation seat (1) and a bracket (2), wherein the upper end of the bracket (2) is fixed on the framework installation seat (1); a back pressure plate (8) is fixed at the lower end of the bracket (2); and a row of rubber woven hoses (7) into the upper half parts of which wood stopper (4) are inserted are clamped between front and back pressure plates (6) and (8). The elastic barrier eliminating device has the advantages of simple and compact structure, firm and reliable installation, large barrier eliminating space, sufficient barrier eliminating rigidity and sufficient flexible buffering performance.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to an elastic obstacle removal device for rail vehicles. Background technique [0002] Rail vehicles are usually equipped with an obstacle removal device before the rolling circles of the two guide wheels of the bogie at the cab end of the train to remove obstacles on the running track. In the prior art, the obstacle removal device is generally a rigid structure, which is fixed on the frame and placed directly above the track and in front of the rolling circle of the wheels. On the one hand, the lower the initial installation height of the obstacle removal device is, the closer it is to the rail surface, and obstacles with smaller heights can be eliminated, which will ensure the safety of the train operation. On the other hand, for the safety of the train operation, The bottom end of the obstacle removal device is not allowed to have rigid contact with the rail, a...
