Medium-low speed magnetic levitation engineering work vehicle

Abstract

The invention discloses a medium-low speed magnetic levitation project work vehicle. The medium-low speed magnetic levitation project work vehicle comprises a compartment (9) and a bogie, wherein the bogie comprises a plurality of single-axle bogie bodies (1); each single-axle bogie body (1) is provided with a guide mechanism; and each guide mechanism comprises a pair of guide wheels (3) in bilateral symmetry and springs (4) used for providing elastic force to support the guide wheels (3) to press the outer side face of an advancing track. The medium-low speed magnetic levitation project work vehicle is provided with the guide mechanisms, under the guide function of the guide mechanisms, it can be ensured that the vehicle drives in the forward direction and the backward direction, especially the stability of turning of the vehicle is ensured, and damage to the track is avoided. In addition, a snow removing and ice melting device (20) and a silencing and noise reducing engine are arranged, serious impact on the living environment of residents is avoided, ice and snow on a magnetic levitation line can be effectively removed under the weather conditions of snowing and raining in winter, and it is ensured that the rainy and snowy weather does not affect safe and normal operation of a medium-low speed magnetic levitation system.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a working vehicle used for overhauling a medium-low speed maglev rail transit system. Background technique [0002] In the medium and low-speed maglev transportation system, considering the construction cost, technical requirements and other reasons, most of the track and contact rail systems are installed on the elevated bridge, and the track and contact rail and other equipment are large in size and heavy in weight. It is inconvenient for heavy equipment to be repaired when there is a breakdown and the space of the viaduct is insufficient. At this time, it is necessary to equip an engineering operation vehicle to assist in the completion of related work. [0003] On the other hand, because the whole line is elevated, when it snows in winter, there will be snow on the track, or even icing, and the suspension and running of the medium and low-speed maglev vehicles are the s...

AI Technical Summary

Problems solved by technology

[0007] First, a major advantage of the maglev line is that the turning radius is small, and the minimum radius can reach 50m. There will be many problems when ordinary two-axis or three-axis bogies are running, such as: poor cornering stability, collision with the track and damage to the track

[0008] Second, the material of the F rail is Q235, which is a relatively fragile steel material, and the hardness of the wheel material is greater than that of the F rail, and it is easy to cause damage to the rail during driving.

[0009] Third, the existing operating vehicles have defects such as slow snow removal and deicing efficiency and incomplete cleaning. In extreme weather, it is difficult to meet the operation requirements of the medium and low speed maglev system

[0010] Fourth, due to thermal expansion and contraction, there will be gaps ranging from 20mm to 40mm between the rail rows, and the collision between the wheels of the existing work vehicle and the rails and the rail seams will generate relatively large noises. Moreover, The working hours of the engineering operation vehicles are generally carried out in the early morning. The maglev rail transit in the city is generally set up with elevated bridges to pass through the residential areas. However, the existing operation vehicles will generate a lot of noise when they are working, which seriously interferes with the passing area. The living environment of residents, although part of the noise can be blocked by setting up soundproof screens, it is still difficult to achieve a satisfactory level
