Frame car body structure of magnetic levitation type rail polling car

Abstract

The invention relates to a frame car body structure of a magnetic levitation type rail polling car, wherein the car body adopts a frame structure formed by welding aluminium alloy extrude section, so as to bear the load of the polling car and realize the double traction pattern of long stator linear motor traction and motor supporting wheel traction, the bottom board of carriage only hangs part of vehicle-bone electrical devices, the two ends are provided with a lift maintenance platform and a car-ground communication device mounting bracket, so as to realize that no device interlayer is arranged. The two ends of the bottom board of carriage are provided with an anti-bumping device and a car coupler, so as to meet part of function requirement of the rail polling car. The frame structure of carriage is short and is provided with four side doors of carriage, and the two ends are provided with a head with a front opening door, and the operating position for the lift maintenance platform is reserved. The middle roof part of the frame structure of carriage is provided with a roof air conditioning, and a hollow compound aluminium alloy cover board is arranged in the spaces at the two sides of the mounted electrical device, so as to ensure ventilation of the vehicle-bone electrical device and adapt to air mechanic pressure change when the polling car meets a passenger train running in high speed of 500km / h.

Description

technical field [0001] The invention relates to a special vehicle structure in the field of high-speed maglev transportation, in particular to a frame body structure of a maglev track inspection vehicle. Background technique [0002] The high-speed maglev transportation system lacks a track inspection vehicle capable of high-speed inspection operation and low-speed measurement operation. The track inspection vehicles designed and manufactured in this field are all supported and driven by wheels, and the guide support wheels are used as a guarantee for the safe operation of the vehicle. However, such traction mode vehicles do not have the conditions for high-speed inspection operation, which makes the maintenance of passenger lines difficult. The "skylight" time is too long, which affects the transportation capacity of passenger lines. In addition, the track inspection vehicle is also required to have the following functions: [0003] 1) Remove any foreign matter on the tra...

AI Technical Summary

Problems solved by technology

[0008] However, the above-mentioned requirements cannot be integrated into a patrol vehicle. The body structure of the original high-speed maglev passenger vehicle has chosen the structure of aluminum alloy extruded profiles and sandwich aluminum alloy composite panels, including the equipment interlayer as the load-bearing structure.

However, such a car body structure does not meet the structural requirements of rail inspection vehicles.

First of all, the equipment interlayer cannot be realized, and the entire load of the vehicle must be borne by the compartment floor

The second is that the space occupied by the motor support wheels on the running mechanism must be considered, which requires that some on-board electrical equipment must be installed in the compartment
