Rail train and equipment compartment thereof

Abstract

The invention discloses a rail train and an equipment compartment thereof. The equipment compartment comprises an equipment compartment frame, an apron board (1) and a positioning component, wherein the lower end of the apron board (1) is hinged to the equipment compartment frame, and the upper end part of the apron board (1) is connected to a train body in a demountable manner; the upper end part of the apron board (1) is positioned to a preset open angle by the positioning component; the positioning component comprises a first pull cord assembly (2) and a second pull cord assembly (9), wherein the first pull cord assembly (2) and the second pull cord assembly (9) are respectively arranged at both end parts of the apron board (1), and the length of at least one of the first pull cord assembly (2) and the second pull cord assembly (9) is adjustable. The rail train and the equipment compartment thereof which adopt a manner that the apron board is positioned by pull rods are simple in structure, and the pull rods are light in weight, so that the reduction of the weight of the whole train is facilitated; besides, the pull cord manner is flexible to use; when small errors exist during the mounting of both ends of the apron board, the apron board can be rapidly opened and normally positioned. In addition, when the apron board is in an open state, the lengths of the first pull cord assembly and the second pull cord assembly can be adjusted equal, so that the phenomenon that one of the first pull cord assembly and the second pull cord assembly severely wears under stress is avoided, and the open clearance of the apron board is very uniform.

Description

Technical field [0001] The invention relates to the technical field of rail trains, in particular to a rail train and its equipment cabin. Background technique [0002] Generally, for high-speed trains, equipment compartments are generally provided at the lower part of the underframe of the car body. Ventilation pipes, installation trunkings and line pipes for undercarriage equipment are laid in the enclosed space of the equipment compartment to realize the Carry out air convection cooling treatment, and protect the equipment under the car from stone hit, freezing and other damage. [0003] The equipment compartment includes the equipment compartment frame, the skirts on both sides and the bottom plate connecting the two skirts. The bottom plate, the skirt plate and the bottom plate of the underframe jointly enclose the equipment compartment space. In order to meet the needs of undercarriage equipment maintenance, the skirts are general It can be detachably installed on the car bo...

AI Technical Summary

Problems solved by technology

[0005] From the above description, it can be seen that whether it is the inspection of the equipment inside the equipment cabin or the replacement of the equipment inside the equipment cabin, the skirt board needs to be completely disassembled. This disassembly process is cumbersome, wastes time, and the maintenance efficiency is relatively low

[0006] In addition, for skirt panels with relatively large volume and weight, the disassembly process generally requires the cooperation of multiple people, which wastes labor costs
