Middle-low-speed magnetic levitation system track beam provided with rescue rails

Abstract

The invention relates to the technical field of magnetic levitation trains, in particular to a middle-low-speed magnetic levitation system track beam provided with rescue rails. The middle-low-speed magnetic levitation system track beam comprises a T-shaped track made of reinforced concrete, the rescue rails and supporting wheels mounted on a train body bogie, wherein mounting grooves are formed in upper parts of a left support arm and a right support arm of the T-shaped track; guide rails are mounted on the lower surfaces of the left support arm and the right support arm; the rescue rails arefixedly mounted in the mounting grooves and arranged along the length of the T-shaped track; when a train is not levitated, the supporting wheels are contacted with the upper surfaces of the rescue rails for supporting, so that the train is supported on the T-shaped track and enabled to move on the T-shaped track. By means of cooperation of the rescue rails and the supporting wheels, rescue movement of the train can be realized, the upper surfaces of the rescue rails are not prone to damage, the service life is long, other magnetic levitation trains are not required to be occupied for rescue,and a smooth and effective rescue process is guaranteed; by means of the integrally manufactured T-shaped track, consistent height of the guide rails on the two sides can be guaranteed, the levelnessmeets the requirement, difficulty of construction is low, the T-shaped track is good in structural strength, so that deformation is effectively prevented, and the service life is guaranteed.

Description

technical field [0001] The invention relates to the technical field of maglev trains, in particular to a track beam of a medium-low speed maglev system with rescue rails. Background technique [0002] The maglev train is mainly composed of three parts: suspension system, drive system and guidance system. In most current designs, the functions of these three parts are all completed by magnetic force. When the suspension system of the train fails and another maglev vehicle is used to tow and rescue the faulty vehicle, the same failure may occur when the rescued maglev train arrives at the rescue location, making it impossible to carry out tow rescue, which will cause the fault to expand; if other rescue locomotives are used to carry out Rescue, the existing track beams cannot provide a stable and reliable support track for the rescue locomotive; figure 1 As shown, the track beam of the existing maglev system generally includes a support beam. The sleepers are fixed and instal...

Problems solved by technology

When the suspension system of the train fails and another maglev vehicle is used to tow and rescue the faulty vehicle, the same failure may occur when the rescued maglev train arrives at the rescue location, making it impossible to carry out tow rescue, which will cause the fault to expand; if other rescue locomotives are used to carry out Rescue, the existing track beams cannot provide a stable and reliable support track for the rescue locomotive; figure 1 As shown, the track beam of the existing maglev system generally includes a support beam. The sleepers are fixed and installed on the support beam by bolts, and then the suspension guide rails on both sides are fixed and installed on each sleeper by bolts. The number of bolts is large, and the installation process is time-consuming and laborious. To ensure the same height and levelness of the suspension guide rails on both sides, the installation error is large, and there may be deformation between the suspension guide rails and the sleeper after long-term use, which will affect the service life
