Embodiment Construction

[0028] like figure 1 , 2 As shown in , 3, a hand brake chain protection device for railway wagons comprises fixed pulley bearings fixed at the end beams of railway wagons and directly below the hand brake chain 3 to form a fixed pulley support 1 and a hand brake fixed on the draw beam. Brake chain protection device 2, fixed pulley support 1 and hand brake chain protection device 2 are butt welded or connected with fasteners.

[0029] like Figure 7 , 8 , 9, the fixed pulley support composition 1 includes a vertically arranged seat plate 1.1, a fixed pulley bracket 1.2, a hand brake chain guard plate 1.3 and a chain guide plate 1.4, and the seat plate 1.1 is provided with a hand-made For the hole of the moving chain, mutually symmetrical fixed pulley brackets 1.2 are welded on both sides of the seat plate 1.1. The fixed pulley bracket 1.2 has a hole connected with the moving pulley, and the top of the fixed pulley bracket 1.2 on both sides is welded with a chain guide plate ...

Abstract

The invention belongs to the technical field of railway wagon braking, particularly relates to a railway wagon hand braking chain protection device and solves the problem that the driving safety is influenced by breaking of a hand brake pull rod reinforcing rib or a hand braking chain. The railway wagon hand braking chain protection device comprises a fixed pulley support assembly fixed at an end beam of a railway wagon and positioned under a hand braking chain relatively and a hand braking chain protection device fixed on a traction beam; and the fixed pulley support assembly and the hand braking chain protection device are in assembly welding or connected through fastening pieces. Through adoption of the railway wagon hand braking chain protection device, the problem that after a conventional hand braking device is released, the hand braking chain droops under the fixed pulley, the release resistance is high since the chain droops greatly to influence the gravity greatly, and thus the hand braking device is not easy to release or cannot be released in place, so that wheels are scratched is solved.

Description

technical field [0001] The invention belongs to the technical field of railway freight car braking, in particular to a hand brake chain protection device for railway freight cars. Background technique [0002] The hand brake is used to produce a braking effect when the railway vehicle is shunting to prevent the parked vehicle from slipping away. The braking ratio is directly related to whether the vehicle can be parked safely as required. Railway wagons usually use a hand brake pull rod that drives a pulley device to amplify the manual force magnification and transmit the hand brake force to the foundation brake device. The original hand brake tie rod reinforcement is welded by 3 round steels with a diameter of 16mm. Due to the sudden change in geometric size, the stress is very concentrated at this place, and the hand brake tie rod reinforcement (that is, 3 If cracks or breaks occur at the welded part of the round steel group), once the reinforcement rib of the hand brake ...
