Fig. 2: the utility model fluid control schematic diagram.

Fig. 3: two, three layers of elevating ram connection diagram of the utility model.

The utility model is reinforced repacking on automobile 12 bases, as shown in Figure 1, the bottom of car chassis 15 is fixed with four "T"-shaped supporting legs 17, two hydraulic actuating cylinders 25 are arranged on each supporting leg 17,26 is flexible with vertical both direction in level to realize supporting leg 17, the upper vertical crossbeam direction of car chassis 15 is preceding, in, post-reinforcing has three crossbeams 13,16,18, four vertical outer columns 14,19 just be fixed on before, after cross member 13,18 two ends, fixed platform 4 just is fixed on four vertical pillars 14,19 middle parts, parallel with car chassis 15, two-layer platform 5 is fixed by flange and four middle level column 24 tops, column 24 bottoms in middle level embed in the vertical outer column 19, and can relatively move, the piston rod of two two layers of elevating rams 8 is fixed with the ball head structure 34 and the bearing at middle beam two ends respectively, and its cylinder barrel is fixing with two-layer platform 5 with hinge 31; Same three layers of platform 3 are fixed by flange and four internal layer column 2 upper ends, internal layer column 2 lower ends embed in the middle level column 24, and can relatively move, the cylinder barrel of two three layers of elevating rams 7 is bundled in respectively on the cylinder barrel of two layers of elevating ram 8 with flange 32,33, and piston is then fixing with hinge 36 and three layers of platform 3.Two, three layers of platform 3.5 are dragged by this two-layer act long oil cylinder 8.7.On about every layer of platform and back, be fixed with 20 turnover panels 21, working area when constructing to increase with hinge 22; Also have removable fence 6, guarantee safety; The light fixture 1 that is used in addition throwing light on, concentrated drainage pipe 20, ladder 11 and retaining vapour hired thug 23, hydraulic control 10 and electric control box 9 all are fixed on the car chassis 15 under the fixed platform 4.

During operation, energized at first, illuminating lamp is bright, allow the cross cylinder 26 of four supporting legs work simultaneously (as shown in Figure 2), it is protruding to drive supporting leg 17, after putting in place, the vertical oil cylinder 25 of supporting leg is worked simultaneously, with till holding up the liftoff and leveling car chassis 15 of automobile travelling wheel 31.Press the button in the electric control box 9 then, make electromagnetic valve work allow the work of two-layer platform oil circuit, because the accurate shunting of flow divider valve 29, make two elevating rams 8 can hold up two-layer platform 5 synchronously, after putting in place, make the electromagnetic valve commutation make the work of three layers of platform oil circuit again, same three layers of platform also can move up synchronously, cut off the hydraulic circuit power supply after putting in place,, make supporting leg 17 and platform 3.5 transfixion for a long time owing to all be connected to bidirectional hydraulic lock 28 in each oil cylinder oil circuit.Because the effect of electromagnetic valve 30 can not worked two-layer platform oil circuit, three layers of platform oil circuit and supporting leg oil circuit simultaneously.
