Example Embodiment

[0034] The core of the present invention is to provide an installation structure for the bottom plate of the equipment compartment, which facilitates the installation of the bottom plate and can reduce the maintenance workload.

[0035] The equipment compartment of the rail vehicle is arranged under the car body, and a closed space is formed by the equipment compartment frame, apron and bottom plate, etc., for installing undercarriage equipment, pipelines and lines.

[0036] Among them, the equipment compartment frame includes frame side beams and frame cross beams. The bottom plate is connected with the equipment compartment frame to close the bottom of the equipment compartment and protect the under-vehicle equipment and pipe lines in the equipment compartment from the vehicle during operation. Damages such as stone strikes and freezing.

[0037] The following specifically introduces the installation structure of the equipment compartment floor. In order to enable those skilled in ...

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...
