Problems solved by technology

Threaded fasteners with higher mechanical properties will increase the cost; larger-sized threaded fasteners will require more structural space, which is not conducive to lightweight design; and the corresponding larger torque requirements will increase the installation cost. Increase the working intensity of personnel or increase special tooling equipment

Abstract

The invention relates to a locomotive vehicle cowcatcher installation structure which comprises a vehicle body, a cowcatcher, an inclined supporting beam, supporting legs, a front vehicle body installation base, a rear vehicle body installation base, supporting leg installation bases and an inclined supporting beam installation base. The front vehicle body installation seat is horizontally fixed at the bottom of the front side of the vehicle body, the supporting leg installation seat is horizontally fixed at the top end of the supporting leg, and the front vehicle body installation seat is fixedly connected with the supporting leg installation seat through a vertical threaded fastener; the inclined supporting beam installation base is perpendicularly fixed to the top end of an inclined supporting beam, the upper end face of the rear vehicle body installation base is fixedly connected with the bottom of the rear side of a vehicle body in parallel, and the lower end face of the rear vehicle body installation base is fixedly connected with the inclined supporting beam installation base in parallel. The lower end face of the rear vehicle body installation base is fixedly connected with the inclined supporting beam through a vertical threaded fastener. The situation that the cowcatcher bears shear force when a threaded fastener is installed is avoided, and the safety coefficient is increased; meanwhile, the axial mechanical performance of the threaded fastener is fully utilized, light weight of the design is facilitated, and the cost and the working intensity of installation personnel are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a mounting structure for a rolling stock obstacle remover. Background technique [0002] The obstacle remover is a component arranged at the front end of the locomotive near the track, and its main function is to remove obstacles on the track when the locomotive is running. According to the industry standard, the obstacle remover needs to resist the pressure of 140KN on the front. At the same time, because the obstacle remover is at the forefront of locomotive operation, its installation reliability is very high. Therefore, in addition to the strength of the obstacle remover itself, the obstacle remover and the locomotive body The connection structure of the steel structure is also very important. Because the obstacle remover needs to be disassembled during daily maintenance or repair, the current connection installation method of the obstacle remover and the car body ...
