Problems solved by technology

The important reason for the limited development of the maglev track is that the track is icy, and there are two main reasons for its vigorous promotion to ensure that it is completely ice-free. Only 8mm, once the track freezes, the maglev train will not be able to float on the surface
Second: From the maintenance point of view, the wheels of the rail inspection vehicle walking on the inner rail surface are rubber wheels. Once it freezes, the rail inspection vehicle will not be able to drive on the track
Heat pipe deicing can deicing in real time, but it consumes too much energy, and it is difficult to install on the magnetic levitation track, so it cannot be applied to magnetic levitation
[0012] To sum up, the current domestic deicing methods are not suitable for rail deicing

Embodiment 1

[0035] Such as Figure 1 to Figure 5 As shown, the track deicing device of the present embodiment includes two frames 1 installed on the front end of the track inspection vehicle 100, and each frame 1 is equipped with a combined deicing system for deicing the track 200 of the magnetic levitation track. Units, two sets of combined deicing units on the two racks 1 deicing the two common monorails of the track 200 respectively, and each combined deicing unit includes a mechanical crushing deicing component 2 and a cleaning deicing component 3 and the heat source deicing assembly 4, the mechanical crushing deicing assembly 2, the sweeping deicing assembly 3, and the heat source outlet 41 of the heat source deicing assembly 4 are sequentially installed on the frame 1 along the direction in which the track inspection car 100 travels, that is, the mechanical The heat source outlets 41 of the crushing deicing assembly 2, the sweeping deicing assembly 3, and the heat source deicing ass...

Embodiment 2

[0041] Such as Figure 6 As shown, the rail deicing device of the present embodiment includes four frames 1 installed on the front end of the rail inspection vehicle 100, and each frame 1 is equipped with a set of combined deicing units for deicing the rail 200 of the magnetic levitation rail A total of four sets of combined deicing units on the four racks 1 respectively deice the upper rail surface and the lower rail surface of the two F-shaped rails of the track 200. The combined deicing unit of this embodiment is the same as that of Embodiment 1.

[0042] The track deicing device is equipped with four sets of combined deicing units, which can meet the characteristics of the magnetic levitation F-shaped track, and deicing the F-shaped track in all directions without dead ends. In other embodiments, according to the rails 200 of different structures, only one or more combined de-icing units may be provided; Multiple sets of combined deicing units are divided into two groups...

Abstract

The invention discloses a track deicing device. The track deicing device comprises a rack installed on a track inspection car, and one or more combined deicing units used for deicing steel rails of tracks are installed on the rack. Each combined deicing unit comprises a mechanical crushing type deicing assembly, a sweeping type deicing assembly and a heat source deicing assembly, wherein the mechanical crushing type deicing assembly, the sweeping type deicing assembly and a heat source outlet of the heat source deicing assembly are installed on the rack in sequence in the advancing direction of the track inspection car. The track deicing device has the advantages of being free of damage to the surfaces of the steel rails, high in deicing efficiency, small in energy consumption, reasonable in structural design, low in manufacturing cost, broad in application prospect and the like.

Description

technical field [0001] The invention relates to the technical field of traffic rail deicing equipment, in particular to a rail deicing device. Background technique [0002] At present, maglev and monorail transportation are emerging industries in China. The medium and low-speed maglev track adopts F-shaped track. The whole track is divided into high and low rail surfaces, and the track is non-conductive. The important reason for the limited development of the maglev track is that the track is icy, and there are two main reasons for its vigorous promotion to ensure that it is completely ice-free. First: from an operational point of view, the distance between the bottom end of the maglev train suspended on the outer track Only 8mm, once the track freezes, the maglev train cannot be suspended on the surface. Second: From the perspective of maintenance, the wheels of the rail inspection vehicle that walks on the inner rail surface are rubber wheels. Once it freezes, the rail i...
