The specific embodiment
As shown in Figure 1, 2: a kind of hydraulic lifting canopy comprises: two preceding cramp bars 3 and two back supporting rods 5 of ceiling 4, supporting ceiling 4; It is characterized in that: cramp bar 3 upper ends are hinged by jointed shaft I 7 and ceiling 4 before described, and the lower end is hinged with the preceding rod bearing 2 that is fixed on the fuselage 1 by jointed shaft III 9; Described back supporting rod 5 upper ends are hinged by jointed shaft II 8 and ceiling 4, and the lower end is hinged with the back rod bearing 6 that is fixed on the fuselage 1 by jointed shaft IV 10; Described jointed shaft I 7, jointed shaft II 8, jointed shaft III 9, jointed shaft IV 10 4 connect to form the parallelogram four-bar linkage structure; Between described back supporting rod 5 and the fuselage 1 hydraulic actuating cylinder 12 is set; Position close with hydraulic actuating cylinder 12 on the described fuselage 1 is provided with Hydraulic Pump 11, is connected by hydraulic pipe between Hydraulic Pump 11 and the hydraulic actuating cylinder 12.
Described back rod bearing 6 is by base plate 6-1 and two mountain font tank brackets that riser 6-2 connects to form; Jointed shaft IV 10 is arranged on riser 6-2 upper end; The upright pin-and-hole 6-3 peace of also making concentric on the two riser 6-2 pin-and-hole 6-4 that crouches, the fixing flat limiting stopper 6-5 that crouches in the inboard of riser 6-2; Bearing pin 6-7 is inserted among upright pin-and-hole 6-3 or the flat pin-and-hole 6-4 of crouching, and bearing pin 6-7 outer end is provided with spring cotter 6-8.
Between the hole of described jointed shaft IV 10 and back supporting rod 5 copper sheathing 6-6 is set.
Described Hydraulic Pump 11 is a fuel priming pump, and its pump rod 11-1 is connected with lengthening bar 11-3 by hinge 11-2, and pump rod 11-1 and lengthening bar 11-3 are sleeved in the hole of sleeve 11-4; Hydraulic Pump 11 bottoms are provided with frame pump rod fixed mount 11-5, and the lengthening bar 11-3 after the bending is installed in the groove of pump rod fixed mount 11-5.
The cylinder body of described hydraulic actuating cylinder 12 and fuselage 1 are hinged, and piston is hinged with the middle part of back supporting rod 5 by cylinder bracket 13.The inlet nozzle place of hydraulic actuating cylinder 12 is provided with check valve.
As shown in Figure 1, 2: when the paver normal operation, ceiling 4 is risen, bearing pin 6-7 is inserted among the upright pin-and-hole 6-3, and locks with spring cotter 6-8, the inclination of bearing pin 6-7 restriction back supporting rod 5, ceiling can not fall.
When paver transition transportation, bearing pin 6-7 is taken off from upright pin-and-hole 6-3, primer fluid press pump 11, to hydraulic actuating cylinder 12 fuel feeding, hydraulic actuating cylinder 12 drive back supporting rods 5 prolong jointed shaft IV 10 and are rotated down.Under the effect of parallelogram four-bar linkage structure, ceiling 4 levels downwards, move forward.When moving to desired location (as Fig. 1, dotted line position shown in Figure 3), back supporting rod 5 lower ends are met the flat positive stop 6-5 of crouching and are stopped.Hydraulic Pump 11 is as working at this moment, and pump rod 11-1 can feel that tangible resistance increases, stop solution press pump 11 work immediately.Again bearing pin 6-7 is inserted among the flat pin-and-hole 6-4 of crouching, and bearing pin is locked,, make back supporting rod 5 stop at horizontal position, also can not move in the transportation together with ceiling 4 in bearing pin 6-7 and the flat limiting stopper 6-5 combined action of crouching with spring cotter 6-8, safe and reliable.
Shown in Fig. 1-5, when paver arrives the construction site, need before the operation ceiling is risen, its process is: take off bearing pin 6-7, primer fluid press pump 11 is to hydraulic actuating cylinder 12 fuel feeding, back supporting rod 5 contrarotations, drive ceiling 4 levels and make progress, move backward, when back supporting rod 5 forwards stand up position to, stop (so the positive stop that has works), 11 work of stop solution press pump, again bearing pin 6-7 is inserted in the hole of upright pin-and-hole 6-3 the swing of restriction back supporting rod 5.
As shown in Figure 5, when Hydraulic Pump 11 does not use, shift sleeve 11-4 the position of lengthening bar 11-3 onto and lengthening bar 11-3 is installed in the groove of pump rod fixed mount 11-5, make pump rod not take too large space.With sleeve 11-4 pump rod 11-1 and lengthening bar 11-3 are connected into a whole stock during use, lighter during hand.
On the hydraulic actuating cylinder 12 check valve is set, when oil pump 11 or transport pipe broke down, check valve forms returned and ends valve and will make hydraulic actuating cylinder 12 keep the beidirectional pressure, and piston rod is motionless, plays second safety effect of restriction ceiling 4 positions.
