Although the moulding of jack is a lot, when the narrow space of construction, part jack can not play a role due to height problem; When supporter or stress point have certain angle, part jack can not meet the supporting condition of construction, and the Leakage of hydraulic jack always can motion-affecting stationarity and accuracy, in addition, hydraulic jack also will consider wall thickness and the bore seal problem of its cylinder body, meanwhile, common small-sized machine formula and hydraulic jack work speed are comparatively slow, and efficiency is low.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of mechanical wedge jack, and stability is high, and adapt to narrow space, easy and simple to handle, work efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of mechanical wedge jack, comprise: firm banking and movable top plate, described movable top plate is set in parallel in the top of firm banking, in described firm banking and movable top plate, correspondence is provided with trapezoid block respectively, first wedge corresponding with trapezoid block and the second wedge is provided with between described firm banking and movable top plate, described first wedge and the second wedge are separately positioned on the two ends of trapezoid block, the adjusting bolt of sensing second wedge is provided with in described first wedge, described second wedge is provided with the tapped bore corresponding with adjusting bolt, the baffle plate that two pieces are vertically pointed to firm banking both sides is symmetrically arranged with outside described movable top plate, described baffle plate is respectively arranged with the vertical waist hole arranged, described firm banking both sides are respectively arranged with the straight pin inserting inside, waist hole.
In the utility model preferred embodiment, the two ends of described trapezoid block are set to the inclined-plane corresponding with the first wedge and the second wedge.
In the utility model preferred embodiment, in described trapezoid block, be respectively arranged with the groove passed for adjusting bolt.
In the utility model preferred embodiment, described first wedge and the second wedge carry out relative motion under the effect of adjusting bolt.
In the utility model preferred embodiment, described baffle plate adopts flathead screw to be fixed on outside movable top plate respectively.
In the utility model preferred embodiment, described adjusting bolt is provided with a packing ring.
The beneficial effects of the utility model are: a kind of mechanical wedge jack that the utility model is pointed out, compact structure, are applicable to using in narrow space, low to the requirement of camp site, angle is flexible, and Stability Analysis of Structures, work efficiency is high, is applicable to rising or the passing of object short distance.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of mechanical wedge jack one of the utility model preferred embodiment;
Fig. 2 is the exploded view of Fig. 1.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of mechanical wedge jack, comprise: firm banking 2 and movable top plate 3, described movable top plate 3 is set in parallel in the top of firm banking 2, in described firm banking 2 and movable top plate 3, correspondence is provided with trapezoid block respectively, first wedge 5 and second wedge 1 corresponding with trapezoid block is provided with between described firm banking 2 and movable top plate 3, described first wedge 5 and the second wedge 1 are separately positioned on the two ends of trapezoid block, the adjusting bolt 6 of sensing second wedge 1 is provided with in described first wedge 5, described second wedge 1 is provided with the tapped bore corresponding with adjusting bolt 6, the baffle plate 4 that two pieces are vertically pointed to firm banking 2 both sides is symmetrically arranged with outside described movable top plate 3, described baffle plate 4 is respectively arranged with the vertical waist hole arranged, described firm banking 2 both sides are respectively arranged with the straight pin 7 inserting inside, waist hole, limit the sense of displacement of baffle plate 4.
The two ends of described trapezoid block are set to the inclined-plane corresponding with the first wedge 5 and the second wedge 1.Screw adjusting bolt 6, first wedge 5 and the second wedge 1 are moved between firm banking 2 and movable top plate 3, with coordinating of trapezoid block, the distance between firm banking 2 and movable top plate 3 is increased by the first wedge 5 and the second wedge 1, serve the effect of lifting or promotion.
Further, the groove passed for adjusting bolt 6 is respectively arranged with in described trapezoid block.
Further, described first wedge 5 and the second wedge 1 carry out relative motion under the effect of adjusting bolt 6.Under the effect of straight pin 7, movable top plate 3 can only produce displacement along between direction, waist hole and firm banking 2.
Described mechanical wedge jack is easy to assembly, and described baffle plate 4 adopts flathead screw to be fixed on outside movable top plate 3 respectively.
Further, described adjusting bolt 6 is provided with a packing ring.
Described mechanical wedge jack structure is firm, and adjusting bolt is the M10 bolt of 70mm, and flathead screw is cross recessed raised countersunk oval head screw.
Mechanical rotation adjusting bolt regulates the distance between the first wedge 5 and the second wedge 1, thus drives the motion of movable top plate 3, plays the effect that lifting supports.This invention belongs to little stroke lifting instrument, and its lift support height is no more than 10mm.
In sum, a kind of mechanical wedge jack that the utility model is pointed out, compact, be applicable to the lifting work in small space, easy to operate, work efficiency is high.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
