Rail wagon as well as brake cylinder installation system and bolts thereof

Abstract

The invention provides a railway wagon as well as a brake cylinder installation system and bolts thereof, wherein the brake cylinder installation system comprises a brake cylinder, a brake cylinder lifting surface and a brake cylinder installation lug, wherein the brake cylinder lifting surface is fixedly connected with the brake cylinder; the brake cylinder installation lug is connected with the brake cylinder lifting surface through an installation assembly; the installation assembly comprises a disconnection-preventing liner plate, disconnection-preventing bolts, a fixed device and a baffle plate, wherein the disconnection-preventing liner plate is arranged below the brake cylinder lifting surface and is provided with a plurality of bolt slotted holes; the disconnection-preventing bolts are connected with the brake cylinder installation lug, the brake cylinder lifting surface and the disconnection-preventing liner plate, the bolt bodies of the disconnection-preventing bolts are provided with groove parts, and the groove parts are clamped in the bolt slotted holes in a penetrating way; the fixed device is tightly fixed below the disconnection-preventing bolts; and the baffle plate is positioned on the side edge of the disconnection-preventing liner plate. The invention ensures that the disconnection-preventing liner plate plays a disconnection-preventing role on the brake cylinder, enhances the reliability of a suspension part of the railway wagon and ensures the safety of railway transportation.

Description

technical field [0001] The invention relates to a safety protection technology for a brake cylinder of a railway freight car, in particular to a railway freight car and its brake cylinder installation system and bolts. Background technique [0002] With the continuous development of railway freight in the direction of heavy load and high speed, higher requirements are put forward for the reliability and safety of railway freight cars, especially the safety protection requirements for the braking system of railway freight cars are very important. At present, the installation of the brake cylinder of the railway freight car braking system in my country generally adopts a simple bolt hoisting structure. Specifically, the connection between the brake cylinder and the brake cylinder installation crane can be fastened with bolts, nuts and washers, and the bolts and nuts Carry out point solidification. [0003] But there is following technical defect in above-mentioned prior art: d...
