The specific embodiment

By Fig. 1 and Fig. 4 as can be seen, rollover dumping car of the present utility model comprises chassis 30, wagon box 1 and main car frame 2.Wagon box 1 comprises two independently cabins 11,101, and the quantity in cabin also can be three or four or five, and all cabin structures are just the same.

In conjunction with shown in Figure 5, each cabin comprises the mechanism 10 of independently turning on one's side.The rollover mechanism 10 in first cabin 11 comprises the jacking cylinder 3 that is fixed in main car frame 2, and jacking cylinder 3 is a multi-stage oil cylinder, and is positioned at the middle part of base plate 12 along fore-and-aft direction.Stablizing when rising for assurance base plate 12, the jacking cylinder 3 preferred middle parts that are positioned at base plate 12 simultaneously along left and right directions.

First cabin 11 comprises that the front apron 61 and back shield 62, the first cabins 11 that are welded on the main car frame 2 also comprise base plate 12, and base plate 12 lower surfaces are connected with three girder steels 13, and girder steel 13 length and base plate 12 equate along the width of left and right directions.Wherein girder steel 13 is positioned at the middle part of base plate 12 along fore-and-aft direction, and the plunger 31 of jacking cylinder 3 girder steel 13 therewith is hinged and connected.

In conjunction with Fig. 2, Fig. 3, Fig. 6, shown in Figure 7, first cabin 11 also comprises the subframe 14 that is positioned on the main car frame 2.Subframe 14 comprises with symmetrical left longeron 141 of the axis of chassis 30 fore-and-aft directions and right vertical beam 142, left longeron 141 and right vertical beam 142 by welding or riveted and fixed on main car frame 2.Left-right longeron 141,142 connects three left crossbeams 143 and 144, three left crossbeams 143 of three right crossbeams and three right crossbeams 144 respectively with the axis of chassis 30 fore-and-aft directions correspondence and left-right symmetric one by one, and is positioned at respectively under three girder steels 13.

Article three, weld left front pivot pin seat 145 and left rear axle key seat 146 respectively on the left crossbeam 1433 of preceding left crossbeam 1431 in the left crossbeam 143 and back, article three, with preceding left crossbeam 1431 symmetric positions welding front right axle key seat 147, weld right back pivot pin seat 148 with left crossbeam 1433 symmetric positions in back on the right crossbeam 1443 in back on the preceding right crossbeam 1441 in the right crossbeam 144.

Have left through hole, right through hole on the girder steel 13 of preceding left crossbeam 1431 and left crossbeam 1433 tops, back.Pivot pin in left front pivot pin seat 145 and the left rear axle key seat 146 passes the left through hole of cooresponding girder steel 13 respectively, pivot pin in front right axle key seat 147 and the right back pivot pin seat 148 passes the right through hole of cooresponding girder steel 13 respectively, by above-mentioned pivot pin girder steel 13 is individually fixed on preceding left crossbeam 1431, the left crossbeam 1433 in back, preceding right crossbeam 1441 and the preceding left crossbeam 1431.

First cabin 11 comprises left hatch door 9 and the right hatch door of driveing respectively at the left and right sides, cabin sidewall 29, on a left side hatch door 9 and the right hatch door 29 the identical locking device of

structure

91,92 is arranged respectively,

locking device

91,92 is fixed in left hatch door 9 and right hatch door 29 closures on the base plate 12 respectively.

Locking device 91 comprises pneumatic dredge pump 72, support arm 74, dead bolt 75, lock shaft 76.The pneumatic dredge pump 72 that is fixedly installed on the base plate 12 comprises pneumatic plunger 721, and pneumatic plunger 721 is movably hinged "＞" shape support arm 74, and support arm 74 middle parts are enclosed within on the little axle 78 rotationally, and little axle 78 is welded on the axle bed 85, and axle bed 85 is welded on the base plate 12.

When support arm 74 rotates around little axle 78, interfere with dead bolt 75 on it.Dead bolt 75 rotatably is enclosed within on the lock shaft 76 by the long slot bore 83 of bottom, and lock shaft 76 two ends are welded in respectively on front frame 81 and the after poppet 82, and front frame 81 and after poppet 82 are welded on the sidewall of base plate 12.The upper end of dead bolt 75 extends upwardly to the top of base plate 12, limits the unlatching of left hatch door 9 with this.

When needs are opened left hatch door 9, air control unit or mechanical traction device stretch out the pneumatic plunger 721 of pneumatic dredge pump 72 left, promoting support arm 74 clockwise rotates around little axle 78, the upper end of support arm 74 upwards promotes dead bolt 75, when dead bolt 75 upward movements, lock shaft 76 slide relative are during to long slot bore 83 bottoms, under the self gravitation effect, dead bolt 75 serves as that axle rotates with lock shaft 76, when dead bolt 75 upper ends rotate to base plate 12 levels or its below, can't limit the unlatching of left hatch door 9, left hatch door 9 promptly is opened.

Unload the goods in first cabin 11 if desired, can open the locking device 91 of left hatch door 9 by the control setup on the vehicle, extract the pivot pin in front right axle key seat 147 and the right back pivot pin seat 148 then, then make the base plate 12 of this bottom, cabin of jacking cylinder 3 jack-up of 11 bottoms, first cabin by the hydraulic control device on the vehicle, so 11 beginnings of first cabin serve as that the axle rotation is tilted with the pivot pin in left front pivot pin seat 145 and the left rear axle key seat 146, left side hatch door 9 is backed down by goods, the goods that order is placed on the base plate 12 unloads from the left side of vehicle, and the goods in this cabin is all unsnatched.

Can also unload goods from right hatch door 29, open locking device 92 with right hatch door 29 by the control setup on the vehicle, extract the pivot pin in left front pivot pin seat 145 and the left rear axle key seat 146 then, then make the base plate 12 of this bottom, cabin of jacking cylinder 3 jack-up of 11 bottoms, first cabin by the hydraulic control device on the vehicle, so 11 beginnings of first cabin serve as that the axle rotation is tilted with the pivot pin in front right axle key seat 147 and the right back pivot pin seat 148, right hatch door 29 is backed down by goods, the goods that order is placed on the base plate 12 unloads from the right side of vehicle, and the goods in this cabin is all unsnatched.

First cabin, 11 structures of wagon box 1 and use and second cabin 101 are just the same.Wagon box 1 is divided into two cabins can realizes unloading in batches, when first cabin 11 tilted, second cabin 101 kept transfixion, treated first cabin, 11 dischargeds answer normal condition, began to make second cabin 101 to tilt to unload again.In the whole like this unloading process, vehicle's center of gravity keeps reduced levels, is not easy to overturn, capsizing case.Avoid simultaneously once unloading too much, sandstone pile up too high flood wheel after, vehicle can't be exercised.

Can make two cabins simultaneously respectively from left and right sides unloading, vehicle's center of gravity does not deflect substantially like this, vehicle stabilization, safety yet.

Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design plan prerequisite; common engineering staff make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
