Embodiment Construction

[0056] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0057] A new type of hand brake device installed on the bottom frame of the railway funnel car (see figure 1 ) is mainly composed of hand brake 1, hand brake bracket 2, fixed pulley 3, vertical lever 4, chain 5, hand brake conversion lever fulcrum seat 6, hand brake conversion lever 7, lever bracket 8, The hand brake chain consists of 9, hand brake pull rod guide frame 10, hand brake pull rod 11 and brake round pins, pull rivets, pull rivet pins, washers and collars.

[0058] Hand brake support 2 is mainly made up of two columns 2.1, 4 beams 2.2, ribs 2.4, fixed pulley support plate 2.5 and chain guard plate 2.6. There are four mounting holes for the hand brake to facilitate the assembly of the hand brake. The fixed pulley support plate is made of steel plate and there are mounting holes for the fixed pulley riveting pin on it. The chain guard...

Abstract

The invention belongs to the technical field of a railway wagon and specifically relates to a hand braking device mounted on a chassis of a railway hopper wagon. The problems of the present hand braking device of the railway hopper wagon are solved. The hand braking device comprises a hand brake, a hand brake bracket, a fixed pulley, a chain assembly, a vertical lever assembly, a hand braking shifter lever fulcrum base, a hand braking shifter lever, a hand braking shifter lever supporting frame, a hand brake chain assembly, a hand brake pull rod guiding frame and a hand brake pull rod. The hand braking device is arranged on a floor of the chassis assembly of the hopper wagon; under the condition of no influence on the function of the hand braking device, the possibility of pulling out the supporting frame by a current hand brake pull rod reinforcing rid of the hopper wagon and the problem of influence on the traffic safety caused by the breaking of the hand brake pull rod are thoroughly eliminated; the demand on the traffic safety of the railway wagon is met.

Description

technical field [0001] The invention belongs to the technical field of railway wagons, and in particular relates to a hand brake device installed on the underframe of a railway funnel wagon. 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, the railway hopper car usually uses a hand brake pull rod arranged under the car body chassis to drive the pulley device to amplify the manual power magnification and transmit the hand brake force to the foundation brake device. The reinforcement rib of the original hand brake tie rod is assembled and welded by three round steels with a diameter of 16 mm. Due to sudden changes in geometric dimensions, the stress is very concentrated here. According to statistics, cracks and breaks in the hand brake tie rod reinforcin...
