Summary of the invention
In order to overcome the deficiency of above-mentioned technology, the present invention provides a kind of easy, safe surface channel device, supplies to be sailed, roll away from into the road analogy testing table efficiently by the examination vehicle.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
Be used for the passage that goes that vehicle sails testing table voluntarily into; Comprise surface channel and surface channel supporting mechanism; The surface channel supporting mechanism is made up of left-hand stringer, intermediate longitudinal girder and right-hand stringer that parallel longitudinal is fixed on the ground; Surface channel is made up of the road surface module that left-right symmetric is distributed between the longeron, and the road surface module is made up of framework, joist steel group and pin, the every corresponding press nips that is fixed on left side or the right-hand stringer of joist steel; Every joist steel is connected with framework through pin; Framework lays respectively at the ground both sides; The ground both sides are provided with road surface module moving guide rail respectively and between the left side, right-hand stringer; The framework bottom is provided with guide wheel and fixing buckle, and guide wheel is positioned on the module moving guide rail of road surface, and fixedly buckle and actuating unit are fixed.
Left and right locating groove is set on the said intermediate longitudinal girder, and said draw-in groove is corresponding with every joist steel respectively.
Every group of road surface module of the present invention moves horizontally under Poewr transmission mechanism drives; Actuating unit is fixed on below the left-right longeron; Said actuating unit is made up of motor, chain drive-belt, transmission shaft and driving chain; Transmission shaft is by the motor-driven of electric control box control, driving chain and fixing snap fit.
The present invention provides the surface channel of going for vehicle or equipment reach simulator stand, has improved the vehicle efficient of testing table up and down greatly, has improved security simultaneously.Modularization, the combined type that is built into through the many groups road surface module surface channel of going, the part closure or openness carry out the demand that road analogy is tested with the adjustment of compatibility test platform actuator position thereby reach the vehicle that adapts to different wheelspans and wheelbase as required.
The present invention avoids the impact of lifting mode to actuator improving vehicle up and down in testing table efficient and the security, can adapt to the needs of different wheelspans, wheelbase vehicle, helps to test adjustment, the operation of actuating system, and safeguard simply, reliability is high.

Embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
As shown in Figure 1; Be used for the passage that goes that vehicle sails testing table voluntarily into, comprise surface channel and surface channel supporting mechanism, the surface channel supporting mechanism is made up of left-hand stringer 4, intermediate longitudinal girder 6 and right-hand stringer 1 that parallel longitudinal is fixed on the ground; Surface channel is made up of the road surface module that left-right symmetric is distributed between the longeron; The road surface module is by framework 2, joist steel group and pin and 3 form, and the joist steel group is arranged in order by several joist steel to be formed, and every joist steel is connected with framework through pin; Framework lays respectively at the ground both sides, in foundation pit, is provided with actuator 5.As shown in Figure 2, every corresponding press nips 8 that is fixed on the left-hand stringer of joist steel; Between left side ground 10 and the left-hand stringer 4 road surface module moving guide rail 9 is set; The framework bottom is provided with guide wheel 11 and fixing buckle; Guide wheel is positioned on the module moving guide rail of road surface; Every joist steel lower surface contacts with the joist steel press nips, the road surface module to intermediate longitudinal girder move horizontally put in place after, every joist steel one end level is inserted and is fixed on the intermediate longitudinal girder 6 in the locating groove 7; The joist steel that need move horizontally is one through pin with frame fixation, together moves, and guide wheel can roll on the road surface module moving guide rail thereunder.Fixedly buckle and actuating unit are fixed.
Every group of road surface module of the present invention moves horizontally under Poewr transmission mechanism drives; As shown in Figure 3; Actuating unit is fixed on below the left-right longeron, and said actuating unit is made up of motor, chain drive-belt, transmission shaft and driving chain, and drive motor 13 drives transmission shaft 14 through chain drive-belt 12 and rotates; Transmission shaft is passed to driving chain 15 to power; Driving chain moves through fixedly buckle fixed thereon 16 drive road surface module level, and the unlatching that realizes the passage road surface is with closed, and transmission shaft is by the motor-driven of electric control box control.
