Description
Technical Field
The utility model belongs to the technical field of large-scale overpass roof beam design and construction and specifically relates to a passage device of sparse maintenance integration based on magnetic levitation track roof beam is related to.
Background
The overhead bridge girder for light magnetic suspension electric car and medium-low speed magnetic suspension train consists of box girder and track panel. The track panel is formed by connecting two tracks into a whole through a sleeper and is arranged on a rail bearing platform protruding from the top of the box girder. The train runs on the tracks on the two sides of the track panel in a non-contact way, and the load transmission path is as follows: the track-sleeper-rail bearing platform-box girder-support-substructure is shown in figure 1.
The floor of the magnetic suspension carriage is a certain distance away from the rail surface, and the rail surface needs to keep a certain height away from the ground in consideration of the requirements of limitation and structural height. Therefore, even in a low road section, the height of the carriage floor is still more than 2m from the ground, and the height of the pier column is required to be increased in an elevated section. Therefore, in an emergency, passengers cannot directly open the vehicle door to evacuate to the ground, and special evacuation measures need to be taken into consideration. In addition, in routine operations, operational maintenance personnel often need to utilize the skylight time of train outages to reach the bottom of the track and the sides of the box girders to inspect components or maintenance equipment.
In the existing structural design, the emergency evacuation requirement cannot be fully considered, and a corresponding space is not reserved for operation and maintenance personnel. For this reason, the following two ways are generally adopted to compensate for the above-mentioned deficiency:
1) by means of a special engineering vehicle, and an operation platform capable of lifting or turning is required to be equipped. And carrying the engineering truck by operation and maintenance personnel to a place needing maintenance, and lowering the operation platform to operate. After the operation, the operation platform is folded and the engineering truck is carried to leave, so that time and labor are wasted, and the efficiency is lower. And the mode is only suitable for maintenance requirements and has no effect on emergency evacuation.
2) Two maintenance channels are additionally built on two sides of the line, the channel structure can be a simple steel structure or a concrete structure, but still needs to be supported on two pier studs, and therefore the pier studs need to be additionally enlarged, and the construction cost is increased. Meanwhile, emergency evacuation is still inconvenient because the car floor is still at a high distance from the maintenance access. Maintenance personnel still need to reach the rail beam top through a portable ladder for operation (such as sleeper inspection), and the operation is inconvenient.
In summary, the existing track structure cannot reliably, simply and inexpensively meet the space requirements of the magnetic levitation train for traffic safety evacuation and operation and maintenance work, and therefore a new magnetic levitation track beam is needed to overcome the above difficulties.
