Railway wagon hand braking device

Abstract

The invention relates to the technical field of wagon braking, in particular to a railway wagon hand braking device, and is aimed at solving multiple problems existing in the existing railway wagon practical application. The railway wagon hand braking device comprises a hand brake and a hand brake mounting seat, a fixed pulley assembly, hand brake chain assembly, a hand brake lever I, hand brake lever guide frames and guide frame mounting seats, a horizontal transmission chain assembly I, a shifter lever, a shifter lever fulcrum seat and a shifter lever bracket, a hand brake lever II, a lever idler hoist, and a horizontal transmission chain assembly II. The brake mounting seat is arranged on an end beam, the hand brake lever guide frames and the guide frame mounting seats are arranged under a side beam at intervals, and the shifter lever fulcrum seat is fixed to a middle beam. The railway wagon hand braking device is arranged near the position under the side beam comprising railway wagon underframes. On the premise that the functions of a railway wagon are not influenced, the problems that reinforcing ribs of an original wagon hand brake lever are possibly pulled out of a bracket and traffic safety is influenced by crack of a hand brake lever are solved completely, and the requirement for traffic safety of the railway wagon is met.

Description

technical field [0001] The invention relates to the technical field of freight car brakes, in particular to a hand brake 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. At present, railway freight cars are usually arranged under the car body underframe, and the hand brake pull rod that drives the pulley device near the center beam is used to amplify the manual force magnification and transmit the hand brake force to the wind brake foundation brake device. The original hand brake tie rod reinforcement is welded by three round steels with a diameter of 16 mm. Due to sudden changes in geometric dimensions, the stress at this place is very concentrated, and it is possible that the hand brake tie rod reinforcement (that is, 3 Cracks a...

Problems solved by technology

[0011] Solve the problem that the hand brake device of the existing railway freight car arranged at the attachment of the middle beam under the car body chassis is difficult to install, inspect and repair due to the bogie and space constraints;

[0012] Solve the problem that the hand brake chain at the movable pulley rubs against the axle or wheel of the railway wagon with a relatively short traction beam structure;
