Abstract
The utility model discloses a moveable jack. A jack is vertically fixed on a base, and vehicle wheels arranged under the base. The utility model is characterized in that the vehicle wheels are composed of a guiding direction wheel and a sliding wheel, the top of the jack is provided with a lifting bracket, and a self-locking device is arranged below the lifting bracket. The utility model has the advantages that the moveable jack can jack up a locking axle of a vehicle which can run continuously or can be drawn away conveniently by a motor vehicle when the vehicle is in the event of the failure, the moveable jack has wide applicability to lifted weights with any geometric-form, and the moveable jack has high load translation stability. A plurality of moveable jacks can conveniently carry large equipment or objects.
Description
Technical field:
The utility model relates to a kind of jack.
Background technology:
The effect of jack is to lift weight, though after existing portable jack can lift weight weight is moved, can avoid the jams, and is not suitable for lifting the weight of any geometric configuration; When vehicle is blown out on express highway, near can not find maintenance point, just car can only be moved to the express highway limit; If miles of relative movement is longer, the speed of this portable jack is slow.
The utility model content:
The technical problems to be solved in the utility model provides a kind of portable jack of the fault vehicle conveniently being removed, can be made things convenient for carrying large equipment or weight.
Solve the problems of the technologies described above, the technical solution of the utility model is: a kind of portable jack, jack 11 is vertically fixed on the base, under the base wheel is installed, it is characterized in that: described wheel is made up of the steering wheel 10 and the sliding wheel 8 of guiding, be provided with lifting bracket 1 at jack 11 tops, self-locking device is below lifting bracket 1.
Lifting bracket 1 is an entity, the main slide bar 3 of jack 11 extend in the hole of the lifting bracket 1 of precision-fit with it, lifting bracket 1 is provided with and anti-ratch 4 precision-fit holes, the top in main slide bar 3 precision-fit holes is provided with the oil circuit that communicates with the top in anti-ratch 4 precision-fit holes in the inside of lifting bracket 1, the top of anti-ratch 4 is gapped, anti-ratch 4 is fixed on the reverse push slab 6, and reverse push slab 6 is positioned at the below of lifting bracket 1, and self-locking device is positioned at the below of reverse push slab 6.Described self-locking device is the chaste tree tooth 5 of living.
Lifting bracket is a cuboid, its middle part is provided with main slide bar 3 precision-fit holes, with main slide bar 3 precision-fit holes is on the concentric circles in the center of circle, and five equilibrium is distributed with four identical anti-ratch 4 precision-fit holes, and main slide bar precision-fit hole depth is more shallow than anti-ratch precision-fit hole.Lifting bracket 1 is provided with detouchable square frame chain 2.Square frame chain 2 is enclosed within on the lifting bracket 1, and uses the bolt horizontal fixed, and the chain of symmetry is arranged on the square frame chain, plays fixation when carrying heavy goods.
The beneficial effects of the utility model are: can follow-up the continuing of jack-up vehicle locking axletree sail when vehicle breaks down (1), is perhaps conveniently pulled away by self-propelled vehicle.(2) applicability is wide, regardless of playing the weight geometric configuration, can both use.(3) heavy burden translation good stability uses several should movable type jack, carrying large equipment or object easily.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further described
Fig. 1 is a structural representation of the present utility model
The specific embodiment:
As shown in Figure 1, under portable jack 11 bases steering wheel 10 and two sliding wheels 8 are installed, the both sides of sliding wheel 8 office bases, it is the equicrural triangle on summit with steering wheel 10 that steering wheel 10 and sliding wheel 8 formed one, and the effect of steering wheel 10 is that this movable type jack is moved towards assigned direction during the heavy burden translation behind the jack-up weight.Above base, the center of gravity place of described equicrural triangle is fixed with jack 11, be provided with the lifting bracket 1 that is attached thereto at the top of jack 11, lifting bracket 1 is provided with detouchable square frame chain, the square frame chain is enclosed within on the lifting bracket 1, and uses the bolt horizontal fixed, and the chain of symmetry is arranged on the square frame chain, when carrying heavy goods, play fixation, can carry the weight of any geometric configuration.Lifting bracket 1 is a cuboid, and the top is V-shape.The cuboid bottom is provided with 5 through holes, and the via depth of middle part is more shallow, and other 4 through holes are positioned on the concentric circles with the more shallow through hole center of circle, and five equilibrium distributes.The more shallow through hole top that is positioned at the middle part is provided with the oil circuit that communicates with the top of other four through holes respectively in the inside of lifting bracket 1, main slide bar 3 precision-fit of more shallow through hole and jack 11 are positioned at four through holes on the concentric circles and anti-ratch 4 precision-fit that cooperate with it.Be provided with the gap between anti-ratch 4 and the through hole that matches, anti-ratch 4 is fixed on the reverse push slab 6, and reverse push slab 6 is positioned at the below of lifting bracket 1, and the below of reverse push slab 6 is provided with chaste tree tooth 5 alive.Reverse change-over valve 9, by the pressurization of the operating mode of general jack, high pressure oil flows into the top of anti-ratch 4 by described oil circuit from the top of main slide bar 3, anti-ratch 4 head rooms are increased gradually, and anti-ratch 4 is fixed on the reverse push slab 6, invariant position.Just make lifting bracket 1 upwards lift certain altitude, make anti-ratch 4 eject reverse push slab 6.Reverse the main slide bar 3 of change-over valve 9 pressurization releases again and make it balance or desired height, play the adjustment equilibrium activity.The chaste tree tooth 5 of living is with the self-locking device after the weight jack-up, can make the not landing under the state of not filling out pressure release of portable jack, when running in the running car when blowing out, can in time lock follow-up continuing with this movable type jack stand axletree and sail; When automobile runs into fault, can just can be pulled away from the position of fault in time with this movable type jack stand axletree locking by general self-propelled vehicle.The below of lifting bracket 1 is connected with guide pillar, and guide pillar inserts in the guide pin bushing, precision-fit between guide pillar and guide pin bushing.Guide pillar guide pin bushing 7 is when the translation of jack-up weight, guarantees that portable jack heavy burden translation is stable.
