Abstract
The invention provides a front rear axle double column automobile elevator. The main structure of the rear axle double column automobile elevator comprises an oil cylinder, a piston bar, a guide pillar, an electrically driven pump and the like. The front rear axle double column automobile elevator is compact in structure, reasonable in design, high in lifting height, safe, reliable, and convenient to move. Besides, labor intensity is greatly reduced, economic benefits are improved, and the front rear axle double column automobile elevator is particularly suitable for repair factories of large-scale carrier vehicles for steel, metallurgy and mining industry.
Description
Technical field:
The invention provides a kind of front-rear axle twin columns auto hoist, belong to the necessary Automobile Service instrument of motor repair trade.
Background technology:
Former automobile maintenance industry adopts mechanical spiral top lifting or fixed type open side type twin columns electrical umbrella point lifting lifting machine, its effort of taking a lot of work, and the power operation people is too near by automobile, inconvenient operation, dangerous, and also noise is large, service life is low, rapid wear.The present invention has overcome defects, and people's operation gets final product, and away from 5～10 meters, automobile, its jacking noise is little, slowly steadily rising, and is safe and reliable, laborsaving.
Summary of the invention:
The invention provides a kind of front-rear axle twin columns auto hoist.Agent structure comprises the compositions such as oil cylinder, piston rod, guidepost, motor-drive pump.
Each parts annexation is as follows: at the bottom of oil cylinder, 13 are welded to connect with outer oil cylinder, after first stage piston bar 4 external diameters and second piston cylinder 6 endoporus phase configuration, second piston cylinder 6 and outer oil cylinder 12 transition fit, guidepost 9 screws with outer oil cylinder 12 screw threads, internal aperture is inserted in second piston cylinder 6 external diameters and is placed in transition fit in outer oil cylinder 12 endoporus, and first stage piston bar 4 microcephalies and registration mast 3 endoporus match.Multi-stage jack is fixed on plane on chassis case 16 with fixing screw 18, and distributing valve 15 is connected by the oily suction pipe of turnover and multi-stage jack.When pressure rise, elasticity pressure-bearing roller descends chassis case 16 is contacted with ground, and jack one-level, secondary rise, otherwise descend.
Compact conformation of the present invention, reasonable in design, lift height is high, safety, reliable, conveniently moving.Greatly reduce labour intensity, improved economic benefit, be specially adapted to the repair shop of iron and steel, metallurgy, the large-scale transport trolley of mining industry.
Description of drawings:
Fig. 1 is front-rear axle twin columns auto hoist constructional drawing.
The specific embodiment:
The main technical details of this lifting machine: rated pressure, 31Mpa, design conduct 600mm, Dan Dingding power 50t; Body height 645mm.
At first with annotating No. 32 antiwear hydraulic oils in the electric oil pump case to oil ga(u)ge, then the two sebific duct female joints of oil pump case valve piece are exposed male joint and screw corresponding to lifting machine valve piece two, feel at once.Switch on power, and lifting machine is put car chassis below, steadily settle, the motor-drive pump switch opens, motor rotation (clockwise direction), the change-over valve handle is moved to the left or to the right, suppose≤be that handle orientations is not right during 10MPa, namely move round about, at this moment piston rod rising gets final product, motor switch stops when rising to certain limit desired location, and motor does not turn, and at this moment not off-load of pressurize gets final product.After using end, operating personal leaves the below, guarantees safety, the rotation of pneumatic switch motor.And simultaneously operating handle is moved round about, piston rod bounces back to original position, cuts off the electricity supply.
The overall height of noting rising in the course of the work must not be guaranteed not superelevation of safety greater than 1100mm, leaves certain leeway, space.
