Description
Technical Field
The invention belongs to a special vehicle in the field of high-speed maglev traffic, relates to a track inspection vehicle, and particularly relates to a normally-conductive electromagnetic suspension type track inspection vehicle.
Background
The invention of the high-speed magnetic suspension transportation technology in the last century draws attention all over the world. After the Shanghai magnetic suspension demonstration line is built and the vehicle is communicated to run, the passenger transport effect is fast, safe and environment-friendly.
As the normally conducting magnetic suspension train carries out passenger traffic at the running speed of 500km/h in the state of 10.0mm of suspension clearance, the safety guarantee of the train running cannot be careless. Therefore, the high-speed magnetic suspension traffic system as the passenger line must perform track inspection before the passenger train runs to ensure that no foreign matters exist on the line track and no deformation exists during the installation and use of the long stator coil, the power supply track, the positioning mark plate and each functional surface. Specifically, as shown in fig. 1, it is a schematic structural diagram of a track 7 of a high-speed normally-conducting electromagnetic levitation transportation system. The main structure part 7f of the track 7 is of a concrete structure, and the track 7 has various functional surfaces, including: the sliding surface 7b, the guide surface 7c, and the stator surface 7d are deformed, out of tolerance, loosened, and the like due to various reasons, and sometimes have foreign matters left on the open-air track, so that it is required to perform track inspection before the maglev train is operated to prevent a train safety accident. On the other hand, long stator coils mounted on rails also need to be inspected to prevent falling cables from intruding into the levitation magnet modules of the train, damaging vehicle components and causing accidents. Therefore, in the high-speed magnetic levitation transportation technology, a rail polling car needs to be provided to complete the safety polling operation.
The track inspection vehicle which is usually used in the past is driven by a supporting wheel structure, is dragged by a diesel (or gasoline) engine, and drives the arranged guide supporting wheel to run on the track. Because the supporting wheel structure can not meet the condition of high-speed operation, the track inspection time is prolonged, and for a high-speed magnetic suspension traffic system of a longer route, if long-time 'skylight' stopping time is reserved for track inspection, the transportation capacity of a passenger line is greatly influenced, so that the track inspection vehicle driven by the supporting wheel structure is difficult to adapt to the use condition of the longer passenger trunk line.
Therefore, the walking structure of the normally-conducting electromagnetic suspension vehicle with high-speed running capability is utilized, the long-stator linear motor traction mode is adopted, and the support wheel structure is arranged on the basis of the long-stator linear motor traction mode to realize the low-speed running detection function, so that the rail inspection vehicle has the high-speed inspection and low-speed detection capability at the same time, and the inspection time is shortened. The walking structure of the normally-conducting electromagnetic suspension vehicle comprises a suspension frame, and a suspension magnet, a guide magnet, an eddy current brake magnet and the like which are arranged on the suspension frame; the running structure enables the suspension frame to turn in time in the running process through the guiding effect of the guiding magnet, and enables the train to have an eddy current braking mode through the eddy current braking magnet.
Therefore, it is first necessary to provide a rail inspection vehicle, which is compatible with the long stator linear motor traction mode and the motor support wheel traction mode, so that the inspection vehicle has the functions of high-speed inspection and low-speed detection, and can clear the rail and inspect the fault condition of each functional surface.
In addition, in the requirements of the magnetic levitation transportation system, the rail polling car must have the following other functions:
1) removing foreign matters on the track;
2) if the track fault is found, the maintenance treatment can be carried out, and the train can pass in a short time;
3) the device has the task of rescuing the accident train;
4) and the track deviation is accurately measured, and a basis is provided for line adjustment work.
However, the above requirements cannot be integrated on a polling car, and the car body structure of the original high-speed magnetic levitation passenger car selects the structure of an aluminum alloy extruded section and a sandwich aluminum alloy composite plate, and comprises an equipment interlayer as a load bearing structure. However, such a vehicle body structure does not meet the structural requirements of a rail inspection vehicle. Firstly, the equipment sandwich cannot be realized, and the whole load of the vehicle must be borne by the floor of the carriage. Secondly, the space occupied by the motor supporting wheels on the walking mechanism must be considered, and therefore part of vehicle-mounted electric equipment must be installed in the carriage.
At present, a vehicle body structure of a magnetic suspension type track polling vehicle, which has light weight, reasonable structure, meets various functional requirements and has proper strength and rigidity, is urgently needed. In view of the above-summarized existing magnetic levitation technologies, it is very necessary to provide a novel track inspection vehicle compatible with dual-traction modes (long stator synchronous linear motor traction and motor support wheel traction), which can implement fast inspection and low speed measurement of a track of a high-speed magnetic levitation transportation system, and can operate by self-rescue under any fault, perform necessary treatment on accidents of a track, and adapt to requirements of a longer main track inspection working environment.

Because the carriage length is relatively short, the double air conditioner configuration of the original passenger transport maglev train is not needed any more, the vehicle-mounted air conditioner 1c is configured on the roof, the carriage structure 1 is only reinforced, the load of the vehicle-mounted air conditioner 1c is supported, and the loosening or the vehicle body strength failure caused by the aerodynamic problem and the vibration problem can be avoided when the inspection vehicle runs at a high speed.
As shown in fig. 3, under-cab skirts 5 are provided on both side surfaces of the floor panel 6 at the cab 1a, and a monitoring device including a high-speed video monitoring system and a high-speed non-contact track detecting device is provided on the inner side of the under-cab skirts 5.
As shown in fig. 3, the traveling structure 2 of the normally conductive electromagnetic suspension type track polling car according to the present invention is fixedly installed at the lower portion of the carriage bottom plate 6, and as shown in fig. 4, the traveling structure comprises 4 suspension frames 2b, a long stator linear motor traction device and an outer rotor motor driving support wheel device, which are sequentially connected, and the long stator linear motor traction device and the outer rotor motor driving support wheel device are arranged on the suspension frames 2 b. The suspension frame 2b comprises 2 connected beam frames, and each beam frame is composed of 2 connected suspension frame beams 2 c; the cross beam 2c is connected to the lower part of the platform floor 6 of the rail inspection vehicle. The long stator linear motor traction device comprises 10 standard suspension magnet modules 2e and 4 lengthened suspension magnet modules 2g which are arranged at two ends of the whole walking structure and are arranged on a suspension frame 2b in a suspension mode, and further comprises 12 guide magnet modules 2f and 2 eddy current brake magnet modules 2d which are arranged on the suspension frame 2b through an articulated piece. The supporting wheel driving devices of the outer rotor motor are arranged on two sides of the suspension frame 2b, namely two ends of a beam 2c of the suspension frame 2 b. The outer rotor motor driving support wheel device comprises outer rotor motor support wheels 2a which are fixedly arranged at two ends of each beam 2 c; the outer rotor motor supporting wheel 2a performs steering motion adapting to a curve of a line along with the steering of the suspension frame 2b through the guiding action of the guiding magnet module 2 f. In the present embodiment, since 2 outer rotor motor support wheels 2a are mounted on each cross beam, that is, 8 outer rotor motor support wheels 2a are mounted on each suspension 2b, a total of 32 outer rotor motor support wheels 2a are finally provided.
Therefore, the walking structure 2 of the magnetic suspension type track polling car provided by the invention realizes a double-traction mode, namely long-stator linear motor traction and outer rotor motor supporting wheel traction. With reference to fig. 1 and 4, the outer rotor motor supporting wheel 2a corresponds to the sliding surface 7b of the track beam 7, the guiding magnet module 2f and the eddy current braking magnet module 2d correspond to the guiding surface 7c of the track 7, and the levitation magnet modules 2e and 2g correspond to the long stator surface 7 d.

Meanwhile, the patrol car disclosed by the invention can realize self-rescue capability under any fault working conditions (including faults of the patrol car, such as partial suspension failure, partial guide failure, external power supply failure and the like, or line track faults, such as long stator cable falling, loosening of fastening bolts of functional parts, deformation of a sliding surface and a guide surface and the like) on the basis of the double-traction mode, namely the track patrol car can return to a maintenance base (or an adjacent station) by using a vehicle-mounted external transmission motor supporting wheel as driving power.
Further, a gas-liquid conversion brake disc (not shown) is further installed on the outer side of the outer rotor motor supporting wheel 2a, so that a gas-liquid conversion disc type brake mode of the invention is realized, and the patrol vehicle is forced to decelerate to stop by using the gas-liquid conversion brake disc in a hydraulic brake mode.
And the other 3 braking modes of the track inspection vehicle are respectively as follows: the inspection vehicle linear motor reverse traction braking mode is realized by the suspension magnet modules 2e and 2g and the long stator coils arranged on the track 7, and the inspection vehicle linear motor reverse traction braking mode forces the inspection vehicle to decelerate and brake by introducing reverse traction current to the long stator coils of the track through a ground traction power supply station. The eddy current braking mode of the inspection vehicle realized by the eddy current braking magnet module 2d forces the inspection vehicle to decelerate and brake according to eight levels by introducing currents of eight levels to the vehicle-mounted eddy current braking magnet module 2 d. The reverse braking mode of the outer rotor motor wheel is realized by the outer rotor motor driving supporting wheel device 2a, and controllable reverse rotation current is introduced to the outer rotor motor driving supporting wheel device 2a to force the inspection vehicle to decelerate and brake. The 4 braking modes can enable the track inspection vehicle to have the function of flexibly and accurately stopping by adopting different methods when track accident points are found, and the track inspection vehicle is suitable for the safe operation function on track lines.
As shown in fig. 5, the normally conductive electromagnetic suspension type track inspection vehicle of the invention is provided with six doors, wherein four carriage side doors 1d are arranged at two sides of the shortened carriage structure 1 and combined with the frame of the aluminum alloy extruded section, and the doors arranged on the two carriages 1a can be opened and closed outwards and upwards and downwards, so that an operator can conveniently enter the operation platform.
The normally-conducting electromagnetic suspension type track polling car is provided with two 200kW diesel generator sets 1f on an aluminum alloy extruded profile frame of a carriage bottom plate 6, so that a vehicle-mounted hybrid power grid is formed, and a current collector power supply mode of an original car (a passenger magnetic suspension train) is not needed. In order to reduce the noise in the vehicle caused by the diesel generator set 1f, the sound-proof cover 1g is specially arranged, so that the noise in the vehicle meets the requirements of the working environment of drivers and passengers.
Because the running mechanism 2 is provided with the external rotor motor driving wheel device, the equipment interlayer of the original vehicle (the passenger magnetic-levitation train) is cancelled, the vehicle-mounted electrical equipment is arranged in the vehicle-mounted electrical equipment installation space 1b at the two sides of the vehicle body, and a part of the vehicle-mounted electrical equipment is fixed below the carriage bottom plate 6 in a hanging manner, so that the arrangement meets the installation requirement of related rail transit vehicle equipment.
A floor upper apron 6c is provided on both sides of the floor 6.
The space of the operation platform 1e is reserved at the two ends of the shortened carriage 1, the carriage bottom plate 6 is of an aluminum alloy extruded profile frame structure, and the self rigidity of the carriage bottom plate 6 is enough to ensure the support of the operation platform 1e reserved at the two ends of the carriage.
