It is arranged in car body 27, is connect with controller 28, probe 13 is positioned close to the position of track.Temperature sensor 16 is for measuring
The temperature of raceway surface illustrates that raceway surface temperature is excessively high, detects a flaw in order to prevent if raceway surface temperature is higher than given threshold
The damage and consideration personnel safety of equipment, control visit inspection vehicle and stop detecting a flaw.
16 signal of temperature sensor, 12 signal of gauging rule are connected to controller 28, probe 13 passes through spy by optical-fibre communications
First 13 line is connected to defectoscope 32, and to prevent defect missing inspection, when work can advance by setting speed, and can according to different sections of highway and
Testing requirements select 27 travel speed of car body；
In addition, being visited when detecting that rail temperature is higher than set temperature, carrying out flaw detection discovery defect or gauge beyond standard requirements
Vehicle automatic alarm is examined, stops visiting inspection.28 pairs of controller acquisitions and the data detected are analyzed, if only high-temperature condition,
Trolley stops flaw detection but can continue on；If becoming out of service in the presence of really defective, in car body 27, can also carry out anti-
Turning, which makes trolley reversing return to fault location, carries out secondary flaw detection confirmation, finally determines defect information；It is wanted if it is gauge beyond standard
When asking, visits inspection vehicle and record the locating information such as mileage and exceeded numerical value.
Photovoltaic electrification component is equipped at the top of car body 27, the photovoltaic electrification component is as shown in Figure 2, comprising: there are several photovoltaics
Board group at photovoltaic board group, the both ends of each photovoltaic panel 9 pass through connecting rod 10 respectively and connect pneumatic valve group, pass through pneumatic valve group
It drives connecting rod 10 to move, and then drives photovoltaic panel 9 along center axis rotation certain angle (- 45 °≤θ≤45 °).
Pneumatic valve group includes: cylinder, is equipped with piston 9-4 that can be up and down in cylinder in cylinder, and piston 9-4 is by gas
Cylinder is divided into two parts, and each section cylinder is all connected with air inlet pipe and an air outlet pipe, is equipped with electromagnetic valve in air inlet pipe and an air outlet pipe；
Two air inlet pipe are connected to air reservoir 9-9, and air reservoir 9-9 connect with the air pressure pump 9-1 being arranged in car body 27, passes through
Air pressure pump 9-1 provides pressure-air to the air inlet pipe.
It should be noted that the motion mode of piston may be designed in circular motion or fan shape moving, connection is driven
Bar movement, also can be realized the rotation of photovoltaic panel.
When photovoltaic panel 9 to be made rotates 45 °, the first escape pipe 9-7 is closed, and the second escape pipe 9-8 is opened, with the first outlet
Electromagnetic valve on the corresponding first air inlet pipe 9-5 of pipe 9-7 is opened, and the valve on the second air inlet pipe 9-6 is closed；Pressure-air
Enter cylinder 9-2 from high-pressure pump by the first air inlet pipe 9-5, at this moment, the side of piston 9-4 pressure because of entrance pressure-air
Increase, and since the second escape pipe 9-8 is opened, so the air on the big one side of pressure is just small to pressure the "top" piston 9-4
One side.Piston rod 9-39-3 is connect with connecting rod 10, and piston 9-4 movement drives 10 activity of connecting rod, living up and down by connecting rod
Dynamic certain distance, so that the rotation of photovoltaic panel 9 joined along center axis rotation certain angle to prevent connecting rod 10 from breaking photovoltaic panel 9
Cushion 11 is in photovoltaic panel 9.It is also same principle that piston 9-4 is mobile to opposite direction.
Air driven pump valve group is divided into two groups, and one group is 1,3,5, No. 7 air driven pump valve group, the life that can be issued by controller 28
Order simultaneously turns on certain angle or all turns on, so that photovoltaic board group is pivoted certain angle (0 to 45 °) angle, another group 2,
4,6, No. 8 pneumatic valve groups, the order that again may be by the sending of controller 28 simultaneously turn on certain angle or all turn on, so that
Photovoltaic board group is pivoted certain angle (0 to -45 °) angle.
It is 0 degree in the most strong high noon angle of flow of sunshine, photovoltaic board group is all parallel to ground, full-load run；And in sunshine
When not strong, appropriate 28 angle of flow of adjusting controller finally makes photovoltaic power generation quantity be optimal effect.
As shown in figure 3, photovoltaic power generation and power supply system 18 all can provide power supply, and mutual backup to visit inspection vehicle.Light
Volt power generation board group concatenates use, (the every piece of photovoltaic panel design output of final output voltage boost to DC220V with photovoltaic booster 17
Voltage is 36V, long 1500mm, wide 1500mm, and the cell piece in photovoltaic panel is 0.5V, can make every piece by photovoltaic booster 17
Photovoltaic panel is pressurized to 60V, and by four pieces of photovoltaic panel concatenation pressurizations of roof, final output voltage is DC220V).
Power supply system 18 is connect with charger 19, voltage needed for charger exports.
Determined by change-over switch 20SA the power supply mode for visiting inspection vehicle be it is any (I and II to connect be photovoltaic power supply, III and
IV connects as city's net power supply).
It uses photovoltaic power generation and urban distribution network to power two systems mutual backup as the charging of lithium battery group 21, energy storage, passes through
It is to visit inspection vehicle frequency converter 25 (Master430 that the design of frequency converter 25 uses Siemens Company) to supply that inverter 22, which exports AC220V,
Electricity, and then dragging motor rotates.Circuit breaker Q F23 is main circuit power switch, and contactor KM24 can examine the hot standby use of vehicle to visit,
When controller 28 issue start command after, frequency converter 25 is connected immediately, visit inspection vehicle motor 26 start, trolley according to predeterminated frequency/
Speed is advanced, and flaw detection and ranging are carried out.
As shown in figure 4, controller 28 passes through optical fiber HMI (man-machine interface), gauging rule 12, defectoscope 32, temperature sensor
16 are communicated, and each electrical appliance state of Various types of data and electrical major loop is collected controller 28 and is handled, is finally sent out
It orders out, visits inspection vehicle according to predetermined frequency and gauge is measured to track flaw detection, infrared gauging rule 12.
Multiple frequency f1 to f4 are provided on frequency converter panel (can pass through SP1 to the address SP4 on Frequency Converter Control panel
It sets f1 to f4) to be used to carry out efficient carrying out flaw detection to track, in order to travel, visit inspection operated quickly and conveniently, it is logical to can use optical fiber
News carry out high, low speed switching undisturbed by frequency converter panel communication to HMI, to inspection vehicle is visited.
During traveling, if front occurs accident or chance emergency and needs to stop, present embodiment devises dual control
The brake modes of four-wheel disc brake processed, i.e. any one of two brake pedals 31 are stepped on, and the brake block of trolley four-wheel can act immediately,
It stops in emergency.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not
Need to make the creative labor the various modifications or changes that can be made still within protection scope of the present invention.
