Railway wagon hand braking device suitable for integrated braking of bogie

Abstract

The invention discloses a railway wagon hand braking device adapting to bogie integrated braking. A bilateral operation hand brake assembly of the device is arranged on the upper plane of a vehicle floor, is close to the end of a vehicle, is fixed through a shaft seat and a hand brake mounting seat, and consists of a hand wheel, a quick release handle, a release shaft, a driving shaft and a bilateral hand brake; the lever fixed fulcrum seat is fixedly welded on a vehicle body; the fixed end of the hand brake lever is mounted on the lever fixed fulcrum seat, the input end is connected with the chain assembly of the hand brakes on the two sides, and the output end is connected with the hand brake lever mounted on the bogie through the hand brake pull rod assembly; the hand brake lever bracket is fixed on a vehicle body; a clamping plate formed by a hand brake pull rod is connected with the output end of the hand brake lever; a pull ring is connected with a chain shoe ring; and the chain shoe ring is connected with a hand brake lever device on the bogie. By means of the device, the purpose of small input and large output can be achieved, and the requirement that different operators meet the larger parking braking rate under the condition that small input force is used is met.

Description

Technical field: [0001] The invention relates to the technical field of railway transportation equipment, in particular to the technical field of hand braking devices for railway freight cars, in particular to a hand braking device for railway freight cars adapted to the integrated braking of bogies. Background technique: [0002] The hand brake device is one of the important components of the railway freight car, which is used when the vehicle is parked or shunted at the station. For the hand brake device of the railway funnel wagon that adopts the integrated braking of the bogie, the hand brake chain is generally lengthened and connected to the hand brake lever on the bogie, and a fixed pulley is set to change the direction. For this structure The hand brake device, when an input force of 560N is applied to the edge of the hand wheel of the hand brake, can meet the parking requirement of a heavy truck with a total weight of 100t and a hand brake rate of ≥13%. Due to the n...

AI Technical Summary

Problems solved by technology

Due to the need to exert a large input force on the edge of the hand wheel of the hand brake and the individual differences of different operators, the work intensity of some operators will be increased, and it is difficult to meet the requirements of the vehicle parking brake. Therefore, the existing structure of the hand The brake device does not meet the requirements of use, and it is urgent to redesign the hand brake device so that a small input force can be applied to the edge of the hand wheel of the hand brake to meet the requirements of the vehicle's parking brake and to meet different operations. individual differences
