Abstract
The utility model relates to a supporting-leg leveling device. The supporting-leg leveling device comprises a lower-part adjusting bolt, a fixed block, a movable supporting leg, a fixed supporting leg box and an upper-part adjusting bolt, wherein the fixed supporting leg box is sheathed with the tail end of the movable supporting leg together; the fixed block is fixed at a lower opening of the fixed supporting leg box; the lower-part adjusting bolt is in threaded connection with the fixed block; the upper-part adjusting bolt is in threaded connection with the tail end of the movable supporting leg. Compared with the prior art, the supporting-leg leveling device has the beneficial effects that the structure is simple, the use is convenient, effects of being the scientific and practical are achieved; by combined movement of the lower-part adjusting bolt and the upper-part adjusting bolt, the drooping amplitude of the outward-extending tail part of the movable supporting leg is effectively adjusted and the occurrence of the phenomenon of no retraction of the movable supporting leg is avoided.
Description
Technical field
The utility model relates to field of mechanical technique, particularly a kind of supporting leg leveling device.
Background technology
Supporting leg is hoisting crane important composition parts, after supporting leg is mainly connected by vehicle frame for supporting vehicle frame, the safety and stability of car load while guaranteeing hoisting crane work, when supporting leg is worked, movable supporting legs stretches out from fixed supporting leg inside, make car load built on stilts, under movable supporting legs stretches out state, because movable supporting legs is subject to powerful external force, cause movable supporting legs sag of chain excessive, because the friction drag between movable supporting legs and fixed supporting leg is large, movable supporting legs is difficult for retracting simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of leveling equipment of simple in structure, easy to use, the sag of chain that regulates movable supporting legs.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of supporting leg leveling device, comprise bottom adjusting bolt, fixed block, movable supporting legs, fixed supporting leg case and top adjusting bolt, described fixed supporting leg case and the tail end of movable supporting legs connect together, fixed block is fixed on fixed supporting leg case end opening place, bottom adjusting bolt and fixed block are threaded togather, and top adjusting bolt and movable supporting legs tail end are threaded togather.
Compared with prior art, the beneficial effects of the utility model are:
A kind of supporting leg leveling device, there is feature simple in structure, easy to use, science is practical, by the aggregate motion of bottom adjusting bolt and top adjusting bolt, effectively regulate the sag of chain of the overhanging afterbody of movable supporting legs, avoided the do not retract generation of phenomenon of movable supporting legs.
Accompanying drawing explanation
Fig. 1 is constructional drawing of the present utility model.
Adjusting bolt 2-fixed block 3-movable supporting legs 4-fixed supporting leg case 5-top, 1-bottom adjusting bolt
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further illustrated:
As shown in Figure 1, a kind of supporting leg leveling device of the utility model, comprise bottom adjusting bolt 1, fixed block 2, movable supporting legs 3, fixed supporting leg case 4 and top adjusting bolt 5, described fixed supporting leg case 4 connects together with the tail end of movable supporting legs 3, fixed block 2 is fixed on fixed supporting leg case 4 end opening places, bottom adjusting bolt 1 is threaded togather with fixed block 2, and top adjusting bolt 5 is threaded togather with movable supporting legs 3 tail ends.
While using the utility model, the combination by bottom adjusting bolt 1 and top adjusting bolt 5 rotatablely moves, and reaches in movable supporting legs 3 telescopic process, controls the sag of chain of movable supporting legs 3 overhanging afterbodys.
Above described in be only groundwork of the present utility model, not the utility model is imposed any restrictions, everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
