The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As Fig. 1～shown in Figure 3: Pneumatic turnover mechanism of the present utility model by last radius stay 1, clump weight 2, down radius stay 3, fixed mount 4, footing 5, cylinder seat 6, cylinder 7, push pedal 8, center shaft 9, bridge plate 10, guardrail 11, rolling bearing units seat 12, be closed to bit switch 13 and be opened to bit switch 14 etc. and form.

The utility model is included in and is fixed with rolling bearing units seat 12 on the fixed mount 4, fixed mount 4 bottoms are provided with footing 5, the center shaft 9 that is rotationally connected in the rolling bearing units seat 12, center shaft 9 is fixedly connected on the stage casing of inside and outside bridge plate 10, be fixed with guardrail 11 on the leading portion of bridge plate 10, be respectively equipped with radius stay 1 and following radius stay 3 in the rear end of bridge plate 10 upper and lower surface, on fixed mount 4, be fixed with cylinder seat 6, be connected with cylinder 7 on the cylinder seat 6, the piston rod end of described cylinder 7 is hinged on push pedal 8 one ends, and the other end of push pedal 8 is fixedly connected on the center shaft 9.Be provided with clump weight 2 in bridge plate 10 rear ends.Be provided with at fixed mount 4 tops trigger when being in horizontality by bridge plate 10 be closed to bit switch 13; The sidepiece of fixed mount 4 be provided with trigger when being in vertical state by bridge plate 10 be opened to bit switch 14.Be closed to bit switch 13 and be fixed on fixed mount 4 tops,, be used to detect slab bridge 10 and close and put in place near the position of going up radius stay 1 under the closed condition.Be opened to bit switch 14 and be fixed on fixed mount 4 sidepieces,, be used to detect slab bridge 10 and open and put in place near the position of the following radius stay 2 of open mode.

Fixed mount 4 is welded by channel-section steel and steel plate, and the footing 5 of fixed mount can be used for the conditioning equipment height; What propulsion source adopted is cylinder 7, links to each other with fixed mount 4 by cylinder seat 6, and the guide rod usefulness connecting panel of cylinder links to each other with the push pedal 8 under the bridge plate 10; Push pedal 8 is welded on the center shaft 9, the side plate welding of center shaft 9 and bridge plate 10 both sides, and the bearing seat 12 of usheing to seat is installed at postwelding center shaft 9 two ends, and bearing seat 12 uses that bolt is counter to be contained on the fixed mount 4.Counterweight 2 uses bolts to be connected with side plate on the bridge plate 10, and bridge plate structural entity center of gravity is positioned on the center shaft 9, thus the load of bearing during the reduction cylinder operation; When cylinder 7 cavity of resorption air inlets, epicoele exhaust, push pedal 8 risings in the guide rod holder, make bridge plate 10 around center shaft 9 left-hand revolutions, and 3 pairs of bridge plates of following radius stay 10 carry out spacing; Otherwise the guide rod band of cylinder 7 push pedal 8 and is descended, and makes bridge plate 10 around center shaft 9 clickwises, and 1 pair of bridge plate of last radius stay 10 carries out spacing.For the safety of staff's operation, on bridge plate, load onto guardrail 11.

The utility model working process is: pneumatic overturn platform is made up of the bridge plate 10 and the guardrail 11 of inside and outside two cover symmetrical structures.Car body enters the desired location, and the pneumatic overturn platform of two covers links to each other two cover flat-bed bridge plates 10 by cylinder 7 closures, forms staff's service platform.After operation was finished, personnel left, and Pneumatic turnover mechanism is opened, and both sides bridge plate 10 is erected, thereby car body can be passed through smoothly.

During beginning, the bridge plate 10 of Pneumatic turnover mechanism is in upright state, and at this moment, the operation of the operator's compartment of main line puts in place, sends signal for the controller of Pneumatic turnover mechanism, allows the bridge plate 10 of Pneumatic turnover mechanism to move to horizontality.Cylinder 7 withdrawals of Pneumatic turnover mechanism, bridge plate 10 is in horizontality, triggers to be closed to bit switch 13, allows the operator to stand on the bridge plate 10 operator's compartment is carried out technological operation.After operation was finished, the operator pressed operation and finishes button, and the cylinder 7 of Pneumatic turnover mechanism stretches out, bridge plate 10 is in horizontality, triggers to be opened to bit switch 14, sends signal for the controller of main line, the operation of permission main line is transported to next station with operator's compartment, enters next circulation.
