Background technology
, it is necessary to carry out ratio of slenderness, rate of wheel load reduction and the experiment of isostatic static test pattern after the completion of rail vehicle design,
Existing test method is to carry out analog orbit superelevation by weighing test platform, using jack stand shaft end, is put between wheel track
Certain altitude cushion block is put to be used for simulating the operating modes such as respective carter superelevation.The method needs to expend a large amount of manpowers；Track lifting precision
It is not enough, it is necessary to be fallen after rise again more than target rising height, larger is influenceed on result of the test；Several shaft end jack lifting speed without
Method ensures consistent；There is the hidden danger that vehicle topples, jack slides in process of the test.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of high-precision orbital superelevation simulated testing system, pass through hydraulic pressure
Controlling track and vehicle, lifting comes measure track lifting altitude and car body lifting altitude together, so that the flexible system to calculate vehicle
Number, sets load transducer to carry out the experiment of rate of wheel load reduction in wheel position.
In order to solve the above technical problems, the present invention provides a kind of high-precision orbital superelevation simulated testing system, its feature exists
In：Including hydraulic control system, mechanical execution system, described hydraulic control system include fuel tank, motor, flow control valve,
Manual directional control valve, overflow valve, direction interlocking check valve, fuel tank connection motor, motor connection traffic control valve, flow control
Valve connects manual directional control valve, and manual directional control valve connects overflow valve, and it is single that overflow valve connects one group of direction interlocking in parallel
To valve, each direction interlocking check valve is connected to hydraulic pressure arm；Described mechanical execution system is sensed including infrared distance measurement
Device, track, crossbeam, support, crossbeam are arranged in support, and track installation is on crossbeam, and it is red that infrared distance sensor includes car body
Outer distance measuring sensor and track infrared distance sensor, car body infrared distance sensor is arranged on the car body lower right corner, and track is infrared
Distance measuring sensor is arranged on the lower right corner of crossbeam.
Toppled hidden danger to eliminate car body during lifting, vehicle bottom is symmetrical arranged safety collar, and theft-resistant link chain one is placed in
Fixed in safety collar, one fixes on the ground, and bogie safety belt is enclosed on the lifting end of four axles of bogie, through crossbeam bottom
The ring internal locking in face.
Compared with prior art, the beneficial effects of the invention are as follows：It is simple in construction, install easy, easy to operate, measurement accuracy

Brief description of the drawings
Fig. 1 is hydraulic schematic diagram of the invention；
Fig. 2 is the front view of the specific embodiment of the invention；
Fig. 3 is Fig. 2 side view.
Embodiment
Reference picture 1, Fig. 2 and Fig. 3, the specific embodiment of the invention include hydraulic control system, mechanical execution system, described
Hydraulic control system include fuel tank 1, two-way hydraulic motor 2, flow control valve 3, manual directional control valve 4, overflow valve 5, pressure
Power table 6, direction interlocking check valve 7, fuel tank connection two-way hydraulic motor, it is ensured that at any time can both direction output torque, two-way liquid
Pressure motor connection traffic control valve, controls the speed of lifting, and flow control valve connects manual directional control valve, lifting is controlled manually
And falling, manual directional control valve connection overflow valve, safety, overpressure protection, pressure gauge monitoring pressure change, overflow valve connection one
Group direction interlocking check valve in parallel, it is ensured that moment can only a direction effect, each direction interlocking check valve connects respectively
Hydraulic pressure arm 12 is connected to, lifting and falling is performed；Described mechanical execution system includes infrared distance sensor, track 14,15
Crossbeam, 16 supports, crossbeam are arranged in support, and track installation is on crossbeam, and infrared distance sensor includes car body infrared distance measurement
Sensor 10 and track infrared distance sensor 11, car body infrared distance sensor are arranged on the lower right corner of car body 8, the infrared survey of track
The lower right corner of crossbeam is arranged on away from sensor, 9 be that track and bogie are overall.
Toppled hidden danger to eliminate car body during lifting, vehicle bottom is symmetrical arranged safety collar 17, theft-resistant link chain 18 1
It is placed in safety collar and fixes, one fixes on the ground, and bogie safety belt 21 is enclosed on the lifting end of 13 4 axles 22 of bogie,
Through the ring internal locking of crossbeam bottom surface, theft-resistant link chain elasticity determines safe clearance according to rising height.
During test, the lifting and falling of hydraulic pressure arm are controlled by two-way hydraulic motor and manual directional control valve.Lift
When rising, hydraulic pressure arm is stretched out, and track ground and crossbeam below and supporting is rotated around the radian of fixed pivot 20 together, rotation
During, car body and bogie also do radian lifting together, due to the presence of ratio of slenderness, cause car body and bogie lifting
Height is different, and the height of lifting is measured by the infrared distance measuring sensor with below the crossbeam on car body respectively
Arrive.Gauge regulation is solved by the mounting means of track and ground 19, and ground-based device is solved by cross mounting groove.
