Railway transportation torpedo car brake device

Abstract

The invention discloses a railway transportation torpedo car brake device. The railway transportation torpedo car brake device comprises a left brake unit, a right brake unit and a brake main air pipe, wherein the brake main air pipe is arranged inside the space, close to the right side, of the bottom of a left end walking portion car underframe of a torpedo car body; the left brake unit is arranged inside the space of the bottom of the two sides of a middle beam, close to the left side, of the left end walking portion car underframe of the torpedo car body; the right brake unit is arranged inside the space of the bottom of the two sides of a middle beam, close to the right side, of a right end walking portion car underframe of the torpedo car body; the brake main air pipe is connected with a locomotive brake air cylinder through a pipeline and connected with a unit brake cylinder of the left brake unit and the left end of a brake movable hose; the right end of the brake movable house is connected with a unit brake cylinder of the right brake unit, and then a closed ventilation pipeline is formed. The railway transportation torpedo car brake device is especially suitable for torpedo cars operating on the occasions with large gradients and needing brake and parking, parking brake is safe and reliable, and influences of high temperature operations on the brake device are reduced.

Description

technical field [0001] The invention relates to the technical field of railway transportation equipment, in particular to a braking device for railway transportation torpedo tank cars. Background technique [0002] The torpedo tank cars of various specifications in the prior art generally do not have a braking function, because in some usage occasions, the running line of the torpedo tank is limited by the site, and has a relatively large slope, and some have a maximum slope of 5.4‰. It is about 3‰. When the locomotive is running with two heavy torpedo tanks on top, the daily speed of the locomotive will decrease due to the relatively large slope. During transportation, the braking ability of locomotives with only 1 / 10 of their own weight is seriously insufficient. In addition, the traction force of locomotives is small and the slope of the railway line is large. In order to increase the braking device, the biggest difficulty is high-temperature operation. The torpedo tank ...

[0002] The torpedo tank cars of various specifications in the prior art generally do not have a braking function, because in some usage occasions, the running line of the torpedo tank is limited by the site, and has a relatively large slope, and some have a maximum slope of 5.4‰. It is about 3‰. When the locomotive is running with two heavy torpedo tanks on top, the daily speed of the locomotive will decrease due to the relatively large slope. During transportation, the braking ability of locomotives with only 1 / 10 of their own weight is seriously insufficient. In addition, the traction force of locomotives is small and the slope of the railway line is large. In order to increase the braking device, the biggest difficulty is high-temperature operation. The torpedo tank body is designed as two separate and relatively independent running parts, and the torpedo tank is used as a link in the middle. First of all, it has a great influence on the temperature of the air source from the locomotive for air braking. Secondly, the tank body must rotate 360 ​​degrees during operation. The above two reasons are the main reasons that restrict the installation of air brake devices on torpedo tank cars.
