Engineering dump truck is the indispensable vehicle in mine transportation and the engineering construction transportation, because of its can be after goods be transported to the destination automatic tipping bucket unload and be widely used.Existing engineering dump truck lifting device adopts single lifting cylinder more, even adopting two lifting cylinder liftings also is simple increase hoisting force, because engineering dump truck is operated in mine and construction site more, very unfairness of ground usually makes the engineering dump truck car load be on the plane inclined, when tipping bucket is unloaded, work along with the lifting cylinder, the wagon box of filling goods raises gradually, setovers when too much when the car load center of gravity line, will cause the car load roll-over accident.For the side force of loading wagon box is controlled, control car load centre offset is too much, prevents car load rollover accident, and the inventor has invented this project dumping car anti-roll hydraulic lifting device.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, low cost of manufacture, safe and reliable engineering dump truck anti-roll hydraulic lifting device, it adopts two oil cylinder liftings, and the top of two oil cylinders in opposite directions near and link with wagon box, extended line intersected equicrural triangle when two oil cylinders were not worked, like this, when oil cylinder lifting wagon box, can keep the wagon box center of gravity to exceed biasing by the stroke of regulating two oil cylinders respectively, prevent the car load rollover, to overcome the deficiencies in the prior art.
The purpose of this utility model is to realize like this, it mainly is made up of car body chassis (1) and wagon box (2), it is characterized in that: on car body chassis (1), be provided with lifting device supporting seat (4), twisted point (32) two ends direct and lifting device supporting seat (4) link respectively under the lifting cylinder of two lifting cylinder (3) lower ends, two pressure sensitive devices (5) are located at respectively on lifting device supporting seat (4) two ends, and be positioned at twisted point (32) below under the two lifting cylinders, on the upper end lifting cylinder of two lifting cylinders (3) twisted point (31) in opposite directions near and with wagon box (2) hinge joint, two lifting cylinder (3) center symmetries.
Wherein: lifting device supporting seat (4) is provided with balance bridge (6), tangle point (61) hinge joint of lifting device supporting seat (4) and balance bridge (6) balance bridge by both middle parts, balance bridge (6) two ends respectively with the lifting cylinder of two lifting cylinder (3) lower ends under twisted point (32) hinge joint, two pressure sensitive devices (5) are located at lifting device supporting seat (4) two ends respectively, and be positioned under the twisted point under the lifting cylinder (32), on the upper end lifting cylinder of two lifting cylinders (3) twisted point (31) in opposite directions near and with wagon box (2) hinge joint, two lifting cylinder (3) center symmetries.
The utility model compared with prior art, the lifting performance is good, safe and reliable, cost is low and be difficult for causing car load rollover.
Description of drawings
Fig. 1 is the utility model lifting cylinder 3 direct and lifting device supporting seat 4 bonded assembly structural representations.
Structural representation when Fig. 2 does not work for the utility model band balance bridge 6.
Structural representation when Fig. 3 is 6 work of the utility model band balance bridge.
Wherein: 1, car body chassis, 2, wagon box, 3, the lifting cylinder, 31, twisted point on the lifting cylinder, 32, twisted point under the lifting cylinder, 4, the lifting device supporting seat, 5, the pressure sensitive device, 6, balance bridge, 61, balance bridge tangles a little.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment 1: referring to accompanying drawing 1, it mainly is made up of the utility model car body chassis 1 and wagon box 2, wherein on car body chassis 1, be provided with lifting device supporting seat 4, twisted point 32 two ends direct and lifting device supporting seat 4 link respectively under the lifting cylinder of two lifting cylinders 3, pressure sensitive device 5 is located on the lifting device supporting seat 4, and be positioned at twisted point 32 belows under the two lifting cylinders, on the upper end lifting cylinder of two lifting cylinders 3 twisted point 31 in opposite directions near and with wagon box 2 hinge joint, and two lifting cylinders, 3 center symmetries.When engineering dump truck rests in level ground work, along with wagon box 2 raises, the car load center of gravity can not be offset, two lifting cylinders 3 are stressed identical, lifting cylinder 3 directly conducts identical to the induction force of pressure sensitive device 5, make two lifting cylinders, 3 collapsing lengths identical by pressure sensitive device 5 so, the car load center of gravity can not setovered all the time so yet.When if engineering dump truck rests on the bevelled ground, along with wagon box 2 raises, the car load center of gravity can be put to car load bevelled one lateral deviation, and this moment, two lifting cylinders 3 were stressed also inequality, be in the power that the lifting cylinder 3 of inclination lower end is subjected to and become big, so stressed this big end makes lifting cylinder 3 strengthen collapsing length by pressure sensitive device 5, simultaneously, a stressed little end makes lifting cylinder 3 reduce collapsing length by pressure sensitive device 5, thereby guaranteed that the car load center of gravity can not setover all the time, thereby guaranteed that car load can not turn on one's side.
Embodiment 2: referring to accompanying drawing 2 and 3, it mainly is made up of the utility model car body chassis 1 and wagon box 2, wherein on car body chassis 1, be provided with lifting device supporting seat 4, lifting device supporting seat 4 is provided with balance bridge 6, lifting device supporting seat 4 and balance bridge 6 tangle by the balance bridge in the middle part of both and a little 61 link, twisted point 32 hinge joints under the lifting cylinder of balance bridge 6 two ends difference symmetry and two lifting cylinders 3, at lifting device supporting seat 4 two ends, twisted point 32 anchor points below is respectively equipped with two pressure sensitive devices 5 under balance bridge 6 and the lifting cylinder, on the upper end lifting cylinder of two lifting cylinders 3 twisted point 31 in opposite directions near and with wagon box 2 hinge joint, two lifting cylinders, 3 center symmetries.When engineering dump truck rests in level ground work, along with wagon box 2 raises, the car load center of gravity can not be offset, two lifting cylinders 3 are stressed identical, lifting cylinder 3 conduction balances that bridge 6 two ends power are identical, and balance bridge 6 is in a state of equilibrium, and balance bridge 6 conduction give the induction force of lifting device supporting seat 4 two ends upward pressure induction installations 5 identical, make two lifting cylinders, 3 collapsing lengths identical by pressure sensitive device 5 so, the car load center of gravity can not setovered all the time so yet.When if engineering dump truck rests on the bevelled ground, along with wagon box 2 raises, the car load center of gravity can be put to car load bevelled one lateral deviation, and this moment, two lifting cylinders 3 were stressed also inequality, be in the power that the lifting cylinder 3 of inclination lower end is subjected to and become big, the power that conduction simultaneously balances bridge 6 respective end is also big than the other end, lifting device supporting seat 4 two ends upward pressure induction installations 5 are given in balance bridge 6 different stressed conduction, a so stressed big end makes lifting cylinder 3 strengthen collapsing length by pressure sensitive device 5, simultaneously, a stressed little end makes lifting cylinder 3 reduce collapsing length by pressure sensitive device 5, thereby guaranteed that the car load center of gravity can not setover all the time, thereby guaranteed that car load can not turn on one's side.
