Abstract
The utility model provides a novel hand double-column oil jack and consists of a special oil jack, a vehicle frame and a special flexible universal wheel. The utility model has simple operation, stable and safe and reliable lifting, and is an ideal tool for maintaining jacks of various motor vehicle; and the utility model has simple structure and low production cost; an ordinary machinery factory can manufacture the utility model. The utility model can also be suitable for various engineering operations.
Description
The utility model belongs to self-propelled vehicle maintenance facility
Self-propelled vehicle comprises small passenger car, minibus, motorcoach, lorry, trac. or the like, and self-propelled vehicle needs place under repair after certain distance of having travelled.Break down if run into vehicle chassis, just need be with vehicle hoisting, traditional oil jack volume is little, and forced stroke is short, only is fit to do driver's tool, just has deficiency as if being used to repair enterprise, uses inconvenience, also collapse accident can take place sometimes.
It is the lifting fulcrum that the purpose of this utility model provides a kind of easy and simple to handle, Yi Cheliang, car body or bumper/spoiler, can be once with vehicle lifting to the manual oil pressure hoist vehicle of safe and reliable twin columns that needs height.
The technical solution of the utility model as shown in Figure 1, two special-purpose oil jacks 1 are fixed on the two ends, top of vehicle frame 2, fix the flexible cardan wheel 3 of four special uses in the long limit of vehicle frame 2 bilateral symmetry.The oil pressing rod of two special-purpose oil jacks 1, fuel-return valve are in the same side, are convenient to operation.
The special-purpose jack 1 of the utility model as shown in Figure 2, the oil circuit of oil hydraulic system is identical with general jack, and shell 4 upper ends be straight barrel type add crown cap 7, piston links into an integrated entity into piston mandril 5 with push rod, remove original adjustment screw rod, on the external diameter of piston mandril 5, be processed with shallow pitch thread and be furnished with shallow tooth nut 6, after piston mandril 5 is raised to certain altitude, shallow tooth nut 6 can be screwed off with 7 contacts of top cap, like this, even oil pressure component failure, piston mandril 5 can not move down yet, guaranteed safe and reliablely, the top 8 has two kinds of flat-top and claw type, and can rotate on piston mandril 5.
Vehicle frame of the present utility model 2 middle parts are high-intensity rectangle unitary constructions, and respectively there is a case ring at two ends, increase aesthetic feeling, are provided with two row's concentric circle holes in vehicle frame 2 abdomens, place oil pressing rod.
The flexible cardan wheel 3 of special use of the present utility model as shown in Figure 3, wheel 9 is installed on the wheel fork 10, wheel fork 10 can move up and down in wheel forked standard 11, and can rotate freely, be connected with steel ball 13 with spring assembly 12 between wheel fork 10 and the wheel forked standard 11, when load, wheel fork 10 just compresses to advance to take turns in the forked standard 11, and vehicle frame 2 just lands and bears load, after load is removed, wheel fork 10 is under the effect of spring, recover original position, this moment, wheel just can roll on the ground, and wheel fork 10 flexibly connects with steel ball 13, can rotate freely, so wheel 9 can be with any change of direction of thrust.
Illustrate:
Fig. 1, the manual oil pressure hoist vehicle of twin columns structural representation.
Fig. 2, special-purpose oil pressure jack structure scheme drawing.
Fig. 3, special-purpose flexible cardan wheel structural representation.
Among the figure: 1, special-purpose oil jack; 2, vehicle frame; 3, special-purpose flexible cardan wheel; 4, shell; 5, piston mandril; 6, shallow tooth nut; 7, top cap; 8, top; 9, wheel; 10, wheel fork; 11, wheel forked standard; 12, spring assembly; 13, steel ball.
Adopt two of the manual oil pressure hoist vehicles of twin columns of the present utility model, can lift whole automobile like a cork, check, keep in repair.Because as the lifting fulcrum, after the vehicle lifting built on stilts, parts such as the suspension on the chassis, vehicle bridge all are in the suspension relaxed state to the utility model, tear open well and repair with car beam, bumper/spoiler or car body.Because the effect of shallow tooth nut 6 is arranged, and vehicle can not descend voluntarily, has guaranteed the safety that repairs.Owing to adopted special-purpose flexible cardan wheel 3, vehicle frame 2 lands when lift jack is worked, and is highly stable, and when lift jack was not worked, the wheel of special-purpose flexible cardan wheel 3 landed, and moved easily.The forced stroke of the utility model piston mandril is long, and an any vehicle all lifting optionally puts in place, uses easily.
After maintenance finishes, earlier piston mandril 5 trace are risen, will revolve on the shallow tooth nut 6, unscrew fuel-return valve more slowly, piston mandril 5 just descends and takes in the oil cylinder, can pull out the manual oil pressure hoist vehicle of twin columns outside the vehicle.
The utility model is simple in structure, and lifting is steady, and is safe and reliable, and productive costs is low, and suitable common mechanical originating firm is produced, and is the desirable lifting facility of the various self-propelled vehiclees of maintenance.
The utility model not only is suitable for various self-propelled vehiclees, also can use in various engineer operations.
