Sinking installation pit 101 is equipped with, the both sides of traveling lane 1 are respectively arranged with limited step 2, one of limited step 2 and are provided with
Guardrail 4, the rear of guardrail 4 is provided with tollbooth 5.Two railing motors 6, each railing are symmetrically arranged with two limited steps 2
A pushing-off the wagons mobile jib 8 is connected with the main shaft of motor 6, two pushing-off the wagons mobile jibs 8 are parallel to each other, pushing-off the wagons from bar 9 be U-shaped structure, pushing-off the wagons
It is slidably mounted on respectively in two pushing-off the wagons mobile jibs 8 from the two ends of bar 9U shapes.The sinking that pushing-off the wagons area 3 is arranged on traveling lane 1 is installed
In hole 101, pushing-off the wagons area 3 is made up of four pushing-off the wagons modules.
Each pushing-off the wagons module includes being uniformly arranged pushing-off the wagons roller lifting area 1001, pushing-off the wagons frame on pushing-off the wagons frame 10, pushing-off the wagons frame 10
10 inner sides are symmetrically arranged with slide 17 respectively at each pushing-off the wagons roller lifting position of area 1001, and each inboard, upright of slide 17 is provided with
Synchronous rack 21.Each inner side of slide 17 is respectively arranged with a hinged-support 19 on pushing-off the wagons frame 10, each hinged-support 19 with
The lower end of lower link 12 is hinged installation, and the upper end and the lower end of upper connecting rod 16 of lower link 12 are hinged, upper connecting rod 16
Upper end is hingedly mounted on synchronizing shaft 20, and the two ends of synchronizing shaft 20 are rotatably installed on two sliding blocks 18 respectively, two sliding blocks 18
Slide up and down respectively in corresponding slide 17, the two ends of synchronizing shaft 20 are also coaxially installed with two synchromesh gears 22, two
Individual synchromesh gear 22 is intermeshed with corresponding synchronous rack 21 respectively.The upper end of two neighboring lower link 12 respectively with one
The two ends of connecting rod 15 are hinged, two neighboring lower link 12 and the middle composition of connecting rod 15 parallelogram sturcutre, adjacent two
Individual upper connecting rod 16 and the middle composition of connecting rod 15 parallelogram sturcutre.Connect during a pair of the middle position of pushing-off the wagons frame 10 are symmetrical
Two ends of the end of bar 15 respectively with an apical axis 14 are hinged, connecting rod 15 during a pair at the end position of pushing-off the wagons frame 10 are symmetrical
Two ends of the end respectively with an apical axis 14 are hinged.The middle position of pushing-off the wagons frame 10 and end are also respectively provided with driving liquid
Cylinder pressure 13, piston rod and the middle part of apical axis 14 of driving hydraulic cylinder 13 are hinged.Part on the symmetrically arranged sliding block 18 of each two
A pushing-off the wagons roller 11 Zhuan Dong be provided with, each pushing-off the wagons roller lifting top of area 1001 is respectively arranged with a spacing anti-rotation block 23,
The circumferential surface of pushing-off the wagons roller 11 has been uniformly arranged tooth type structures, and spacing anti-rotation block 23 is provided with arc-shaped surface, arc-shaped surface and set
There are tooth type structures, it is possible to cooperate with pushing-off the wagons roller 11, when being dropped down onto under the two ends of pushing-off the wagons roller 11 on spacing anti-rotation block 23, pushing-off the wagons
Roller 11 is intermeshed with the tooth type structures on spacing anti-rotation block 23, prevents pushing-off the wagons roller 11 from rotating.
Hydraulic power unit 7 is additionally provided with limited step 2, is that driving hydraulic cylinder 13 provides hydraulic power.Pushing-off the wagons is from bar 9 with blocking

The number of degrees are between 100 ° ~ 110 °.
Operation principle of the present invention：In the use of the present invention, original state of the invention is that the two ends of pushing-off the wagons roller 11 fall first
On to spacing anti-rotation block 23, now the piston rod of driving hydraulic cylinder 13 is in retracted mode；Due to adjacent in each pushing-off the wagons module
Lower link 12 be mutually hinged by middle connecting rod 15, and two neighboring lower link 12 and middle connecting rod 15 composition are flat
Row quadrilateral structure, two neighboring upper connecting rod 16 and the middle composition of connecting rod 15 parallelogram sturcutre, therefore when driving hydraulic pressure
The piston rod of cylinder 13 from retracted mode be changed into be in stretching state when, pass sequentially through apical axis 14, middle connecting rod 15, lower link 12, on
Connecting rod 16, finally makes vertical direction of the sliding block 18 along slide 17 move upwards, while synchromesh gear is along synchronous rack gear motion,
Now pushing-off the wagons roller 11 lifts rise from spacing anti-rotation block 23, and free to rotate, so as to will have the vehicle for rushing card intention from ground
Face lifts, and its power is not implemented, and finally realizes the lossless purpose for intercepting and rushing truck；While two in each pushing-off the wagons module
The individual action of driving hydraulic cylinder 13 keeps synchronous consistent；Because pushing-off the wagons from bar 9 is U-shaped structure, pushing-off the wagons is slided from the two ends of bar 9U shapes
In two pushing-off the wagons mobile jibs 8, pushing-off the wagons is equipped with elastic element from bar 9 and the connecting portion of pushing-off the wagons mobile jib 8, it is ensured that bumps against and blocks in vehicle
Car will not form rigid shock after bar 9, to prevent causing to damage to vehicle and vehicle stopping device.
