Description
Technical field
The utility model relates to a kind of instrument of vehicle maintenance and repair, is specially a kind of jack-up automobile that is used for and waits to unload the jack that wheel is convenient to unload the wheel maintenance.
Background technology
The existing jack-up automobile that is used for unloads the jack that wheel keeps in repair, need manually pull the rocking handle of jack, it is time-consuming to require great effort, particularly the large-scale autotruck of ten to tens tons of load carrying abilities uses existing jack, and it is time-consuming not only very to require great effort, and be absolutely unsafe during manual operation, dangerous big, unload in the wheel maintenance at automobile, because of the accident of using existing jack to cause people's injures and deaths happens occasionally.
The utility model content
The purpose of this utility model will overcome existing car jack exactly, unload the deficiency of the jack of wheel maintenance especially for large-scale bogie, provide a kind of automobile self power jack-up wheel to be unloaded that utilizes, not only laborsaving saving time, and safe and reliable automobile-used automatic jack.
For achieving the above object, the technical solution of the utility model is, this automobile-used automatic jack comprises bearing, bottom at described bearing is provided with roller, in described bearing, be provided with a column casing, be provided with elastic body and pillar in this column casing, this elastic body can be provided in a side of the spring below the described pillar, is provided with attaching parts in the upper end of this pillar.When wheel that needs unload reaches on the wheel pad of providing for oneself, this wheel and wheel bridge thereof raise, just the automobile-used automatic jack of the utility model can be placed this moment wheel pad next door to wait to unload under the wheel bridge of wheel, and by its elastomeric elastic force and on pillar and attaching parts and wheel bridge attached together, then car is left down the described wheel pad of providing for oneself, and this automobile-used automatic jack companion is meanwhile moved, and carry the weight of cycling start gradually, make that to wait to unload wheel unsettled, so that unload the wheel maintenance, after having keeped in repair, repeat said process, to take off this automobile-used automatic jack, recover with the wheel load-bearing.
Top at described pillar is provided with detent mechanism, so that change end connection height overhead on the described pillar as required, makes this automobile-used automatic jack be fit to the different automobile of wheel bridge height.This detent mechanism can be a screw nut.
Be provided with the wheel pad on the next door of the automobile-used automatic jack of the utility model, this is taken turns, and the pad middle part is thick, two ends thin.This takes turns pad also can provide the next door that places described automobile-used automatic jack for oneself.
The described spacer of taking turns has its height adjustment mechanism, to adapt to different automotive uses.
As improvement of the present utility model, on described bearing, be provided with described elastomeric regulating mechanism.
As another kind of improvement the of the present utility model, the upper surface of described attaching parts is a nonplanar structure, so as when running car better attached on the wheel bridge.
Compared with prior art, the automobile-used automatic jack of the utility model is by automobile self power, make its wheel at first open the wheel pad, wheel and wheel bridge are raise, so that load onto the automobile-used automatic jack of the utility model, this moment is owing to elastomeric elastic force in the bearing with by pillar and attaching parts thereof on it, make this automobile-used automatic jack can be tightly attached on the wheel bridge, then under the further driving of the power of automobile own, wheel leaves down and leaves the wheel pad, and this automobile-used automatic jack companion is meanwhile moved, and replacement wheel pad carries car weight gradually, make wheel unsettled, to unload the wheel maintenance; After unloading wheel maintenance well, repeat said process, then can take off described automobile-used automatic jack, recover to carry with wheel.The utility model has utilized the power of automobile self dexterously, and its wheel and wheel bridge are raise, and its weight is all transferred on the automobile-used automatic jack of the utility model, make wheel unsettled, so that unload the wheel maintenance, not only laborsaving saving time, and also safe and reliable.
The specific embodiment:
Fig. 1 is the utility model cutaway view.
The wheel pad cutaway view that Fig. 2 adopts for the utility model.
As shown in Figure 1 and Figure 2, the automobile-used automatic jack of the utility model, comprise bearing [1], be provided with roller [7] in the bottom of bearing [1], be provided with a column casing [2] at the middle part of bearing [1], in a column casing [2], be provided with elastic body [6] and pillar [3] from bottom to top successively, elastic body [6] is a spring, be provided with attaching parts [4] in the upper end of pillar [3], attaching parts [4] is a concave body, be provided with the regulating mechanism (this figure does not draw) of elastic body [6] on bearing [1], be provided with wheel pad [8] on the next door of bearing [1], this takes turns pad [8] for trapezoidal.
During use, the wheel pad [8] that the utility model is set up or provided for oneself is placed on the front or rear side who waits to unload wheel, starting automobile makes wheel to be unloaded climb up the top that this takes turns pad [8], this automobile-used automatic jack can be put into wheel pad [8] next door this moment by waiting to unload under the wheel wheel bridge on one side, the regulating mechanism of operating flexibility body [6] discharges elastic force, attaching parts [4] is raise and tightly be attached to and take turns on the bridge, continuing to start automobile then makes and waits to unload wheel from lower whorl pad [8], this moment, described automobile-used automatic jack also and then moved, and carried car weight gradually, make that to wait to unload wheel unsettled, so that unload wheel maintenance; After having keeped in repair, repeat said process, recover with the wheel load-bearing to take out this automobile-used automatic jack.Its laborsaving saving time, safe and reliable.
