Brief description of the drawings
Fig. 1 is hydraulic schematic diagram of the present utility model；
Fig. 2 is the front view of the utility model embodiment；
Fig. 3 is Fig. 2 side view.
Embodiment
Reference picture 1, Fig. 2 and Fig. 3, the utility model embodiment include hydraulic control system, mechanical execution system,
Described hydraulic control system includes fuel tank 1, two-way hydraulic motor 2, flow control valve 3, manual directional control valve 4, overflow valve
5th, pressure gauge 6, direction interlocking check valve 7, fuel tank connection two-way hydraulic motor, ensure at any time can both direction output torque, it is double
To hydraulic motor connection traffic control valve, the speed of lifting is controlled, flow control valve connects manual directional control valve, manual to control
Lifting and falling, manual directional control valve connect overflow valve, safety, overpressure protection, pressure gauge monitoring pressure change, overflow valve company
Connect one group of direction interlocking check valve in parallel, ensure a moment can only a direction effect, each direction interlocking check valve point
Hydraulic pressure arm 12 is not connected with, performs lifting and falling；Described mechanical execution system includes infrared distance sensor, track
14th, 15 crossbeams, 16 supports, crossbeam are arranged in support, and for track installation on crossbeam, it is infrared that infrared distance sensor includes car body
Distance measuring sensor 10 and track infrared distance sensor 11, car body infrared distance sensor are arranged on the lower right corner of car body 8, and track is red
Outer distance measuring sensor is arranged on the lower right corner of crossbeam, and 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 of hydraulic pressure arm and falling are controlled by two-way hydraulic motor and manual directional control valve.Lift
When rising, hydraulic pressure arm stretches out, and track ground and crossbeam below and support rotate 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 solves by the mounting means of track and ground 19, and ground-based device solves by cross mounting groove.
