Abstract
The utility model discloses a lifting mechanism of a road wrecker and belongs to lifting mechanisms of engineering vehicles. The lifting mechanism comprises a first fixing seat, a scalene four-bar linkage, a vertical arm, a swinging arm, an arm-bent oil cylinder, a second fixing seat and a vertical oil cylinder. The first fixing seat and the second fixing seat are welded on an auxiliary frame of the road wrecker. The scalene four-bar linkage is connected with the first fixing seat. The vertical oil cylinder is connected with the second fixing seat. The vertical arm is respectively connected with the scalene four-bar linkage, the vertical oil cylinder and the arm-bent oil cylinder. The swinging arm is respectively connected with the vertical arm and the arm-bent oil cylinder. The lifting mechanism of the road wrecker has the advantages of saving a slide and a sliding block, enabling self-friction-force to be reduced in the whole lifting process, improving energy utilization rate, meanwhile reducing the size of the built-in arm-bent oil cylinder, and saving cost. In addition, the lifting mechanism of the road wrecker is simple in structure and convenient to manufacture, and solves the defects that in the past, one vertical oil cylinder is used for driving the swinging arm to only move horizontally and vertically, and the swing arm can not move upwards with one end perked.
Description
Technical field
The utility model relates to the lift mechanism of a kind of lift mechanism of engineering truck, particularly a kind of road obstacle clearing vehicle.
Background technology:
Cleaning vehicle or vehicles peccancy need to utilize the lift mechanism of wrecker sometimes, vehicle front-wheel or trailing wheel are lifted to hold in the palm lead, and fault vehicle bottom raising height will satisfy certain requirement like this.Common are at present following two kinds of mechanisms:
1, sliding type lift mechanism.During work, slideway and slide block need to be arranged, between slideway and the slide block owing to can be produced very large friction force by the motorcycle action of gravitation.Its rear portion is lifted oil cylinder with one and is finished and prop up function, and when lifting cylinder movement, up and down translation of swing arm can not have been sticked up, and the height that hoists is restricted, and the out of reach requirement affects the cleaning of fault vehicle.
2, parallel four-bar linkage.During work,,, can be realized having sticked up action by the built-in folding arm oil cylinder of upright arm with up and down translation of swing arm by motorcycle, satisfy requirement for height, but the folding arm cylinder sizes be bigger than normal.
Summary of the invention:
The utility model purpose is the lift mechanism that a kind of wrecker will be provided, solve larger to the dimensional characteristic of built-in folding arm oil cylinder, holder when leading to the problem of fault vehicle lift height.
The utility model purpose is achieved in that this lifting apparatus comprises the first permanent seat, scalene four connecting rods, upright arm, swing arm, folding arm oil cylinder, the second permanent seat and Vertical Cylinders; The first permanent seat and the second permanent seat are welded on the subframe of wrecker, scalene four connecting rods link to each other with the first permanent seat, Vertical Cylinders links to each other with the second permanent seat, upright arm links to each other with scalene four connecting rods, Vertical Cylinders, folding arm oil cylinder respectively, and swing arm links to each other with the folding arm oil cylinder with upright arm respectively.
Beneficial effect owing to adopted such scheme, lift mechanism to be installed in the afterbody of wrecker, when lifting vehicle, has three cylinder movements, and when wherein being built in the folding arm cylinder movement of upright arm, swing arm rotates around hinge, finishes the receipts of swing arm and puts; When swing arm is put down fully, be installed in the two Vertical Cylinders motion on the second permanent seat, when swing arm moves up with scalene four connecting rods, upwards sticked up.The utility model has compared with prior art saved slideway and slide block, makes the whole friction force that has deducted self in the process of lifting, and has improved energy utilization rate.Because the folding and unfolding when the folding arm oil cylinder only is responsible for swing arm and is not lifted weight, thereby greatly reduce the size of built-in folding arm oil cylinder, saved cost.
Advantage: this lift mechanism is rational in infrastructure, simple, practical.Slideway and slide block have been saved, make the whole friction force that has deducted self in the process of lifting, improved energy utilization rate, reduced simultaneously the size of built-in folding arm oil cylinder, saved cost, and simple in structure being easy to make, changed in the past with a Vertical Cylinders drive swing arm can only about translation and the drawback that can not upwards stick up.
Description of drawings:
Fig. 1 is constructional drawing of the present utility model.
Fig. 2 is falling state constructional drawing of the present utility model.
Fig. 3 is pop-up structure graph of the present utility model.
Among the figure, the 1, first permanent seat; 2, scalene four connecting rods; 3, upright arm; 4, swing arm; 5, folding arm oil cylinder; 6, the second permanent seat; 7, Vertical Cylinders.
The specific embodiment:
Below in conjunction with accompanying drawing present embodiment is described further:
Embodiment 1: this lifting apparatus comprises the first permanent seat 1, scalene four connecting rods 2, upright arm 3, swing arm 4, folding arm oil cylinder 5, the second permanent seat 6 and Vertical Cylinders 7; The first permanent seat 1 and the second permanent seat 6 are welded on the subframe of wrecker, scalene four connecting rods 2 link to each other with the first permanent seat 1, Vertical Cylinders 7 links to each other with the second permanent seat 6, upright arm 3 links to each other with scalene four connecting rods 2, Vertical Cylinders 7, folding arm oil cylinder 5 respectively, and swing arm 4 links to each other with folding arm oil cylinder 5 with upright arm 3 respectively.
Lift mechanism is fixed on the afterbody of wrecker, the first permanent seat 1 and the second permanent seat 6 are welded on the subframe of wrecker, swing arm 4 is along with the motion of folding arm oil cylinder 5, finish folding and unfolding, upright arm 3 and scalene four connecting rods 2 are along with the motion of Vertical Cylinders 7, when moving up with swing arm 4, upwards stick up the requirement to fault vehicle lift height when satisfying holder and leading of certain angle.
Along with the contraction of folding arm oil cylinder 5, swing arm 4 rotates around hinge O until put down fully, along with the contraction of Vertical Cylinders 7 when lifting the fault vehicle, swing arm 4 is transferred to ground, along with stretching out of Vertical Cylinders 7, in the time of swing arm 4 upward movement, upwards stick up certain angle, held up disabled vehicle.
