Systematized installing structure of roof equipment of urban rail vehicle

Abstract

The invention provides a systematized installing structure of roof equipment of an urban rail vehicle. The systematized installing structure comprises a vehicle body top (8) of the vehicle and a roofequipment box body (1). An opening (9) is formed in the vehicle body top, and cross beams (3) fixedly connected with a vehicle boy top longitudinal beam (11) are arranged at the front end and the rearend of the opening respectively. Top installing bases (2) are arranged on the middle portions of the front end and the rear end of the roof equipment box body respectively, after the bottom of the roof equipment box body submerges into the opening, the top installing bases are arranged on the cross beams and fixedly connected with the cross beams, and a flange (4) is arranged between the roof equipment box body and the opening to form pressure welding sealing. Drought fans (5) are arranged on the two sides of the roof equipment box body, and an air inflow air flue (10) communicated with a waste exhaust duct of a passenger compartment is arranged at the bottom of the roof equipment box body. The installing height of the roof equipment box body and the gravity center height of the vehicle are reduced, the exposure amount of the equipment box body is reduced, the attractiveness is improved, and the active waste exhaust and pressure welding watertightness functions are achieved.

Description

technical field [0001] The invention relates to urban rail transit vehicles, in particular to a systematic installation structure for roof equipment of urban rail vehicles. Background technique [0002] For urban rail transit vehicles, it is necessary to install a roof equipment box with a large volume and weight on the roof. For existing urban rail transit vehicles, such as subways, trams, light rails, etc., the roof equipment is generally installed on the roof platform, and the installation height is limited by the height of the roof platform; the ventilation method of the roof equipment is generally forced by the box itself. Air-cooling or natural air-cooling, in high-temperature areas, the temperature of the inhaled air is high, which is not conducive to heat dissipation; the equipment sealing method generally adopts self-sealing or glue sealing, and the self-sealing method is not conducive to maintenance of equipment from the passenger room, and glue sealing is limited ...

Problems solved by technology

For existing urban rail transit vehicles, such as subways, trams, light rails, etc., the roof equipment is generally installed on the roof platform, and the installation height is limited by the height of the roof platform; the ventilation method of the roof equipment is generally forced by the box itself. Air-cooling or natural air-cooling, in high-temperature areas, the temperature of the inhaled air is high, which is not conducive to heat dissipation; the equipment sealing method generally adopts self-sealing or glue sealing, and the self-sealing method is not conducive to maintenance of equipment from the passenger room, and glue sealing is limited Due to the sealing process and the life of the sealant, the sealing reliability needs to be improved

Domestic urban rail transit vehicles have not yet seen a systematic installation structure for equipment boxes that adopt a sunken structure and have active waste discharge and crimping watertight functions
