Installing structure of device cabin bottom plate

Abstract

The invention discloses an installing structure of a device cabin bottom plate; a bottom plate is fixedly connected to a framework side girder of a device cabin in a detachable mode; a sliding rail is fixedly connected to one side of the bottom plate and the side of the bottom plate is jointed with a framework beam of the device cabin; a concave part is arranged on one of the sliding rail and the framework beam and a convex part is arranged on the other one of the sliding rail and the framework beam. According to the installing structure, the connection between the bottom plate and the framework beam is achieved by clamping the concave part with the convex part, the connecting piece between the bottom plate and the framework beam can be saved, the number of the connecting piece can be greatly reduced, the bottom plate is convenient to installed, overhaul workload is reduced and the work efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an installation structure for an equipment cabin floor. Background technique [0002] For existing rail vehicles, such as urban light rail, passenger trains, EMUs, etc., in order to save space in the vehicle and facilitate the installation and configuration of pipelines and lines for equipment devices, the relevant vehicle equipment is usually arranged under the chassis of the vehicle body to form a Equipment compartment under the vehicle. [0003] When the rail vehicle runs at high speed, it will generate a strong air pressure wave, which will make the small stones or other objects near the bottom of the vehicle and the track be sucked up. In order to prevent these objects from hitting the equipment under the vehicle in the equipment compartment, the safety of the vehicle is ensured. For operation, a bottom plate is usually installed at the bottom of the equipment compart...

Problems solved by technology

[0007] In order to ensure the reliability of the installation of the base plate 12, multiple sets of bolts 13 need to be provided for the connection between the base plate 12 and the beam of the frame 11. There are too many connecting parts, which is not only inconvenient for the installation of the base plate 12, but also inconvenient for maintenance. The bolts 13 can only be carried out, and all the bolts 13 must be re-tightened after the maintenance to realize the fixation between the bottom plate 12 and the equipment cabin frame 11, resulting in excessive maintenance workload
