Abstract
The invention relates to a part of equipment machinery, and particularly relates to a self-adaptive landing leg of the equipment machinery. The self-adaptive landing leg comprises a landing leg sleeve and base plates, wherein a plurality of first single lugs are arranged at the tail end of the landing leg sleeve at intervals, the landing leg sleeve is further internally provided with an inner retractile rod, and the tail end of the inner rod is provided with a plurality of second single lugs; the base plates equal to the first single lugs and are provided with third single lugs, the third single lugs are hinged with one ends of connecting rods, and the other ends of the connecting rods are hinged with the first single lugs; and each of the base plates is further provided with double lugs connected with the second single lugs. The self-adaptive landing leg provided by the invention can be applied to various soils with macadam, cobblestones and the like, and can enhance the stability of the equipment with the self-adaptive landing leg.
Description
Technical field
The present invention relates to a kind of equipment mechanical part, especially a kind of supporting leg of equipping machinery.
Background technique
Engineer equipment such as steel structure bridge, working platform and machinery in order to improve stability, need a plurality of supporting legs to support usually.Supporting leg need provide enough support stiffnesses, and can excellent adaptability be arranged to ground.Mostly the dunnage of current leg structure is flat type; It promptly under the load-bearing state rigid plane; A kind of stabilizing leg and dunnage are disclosed like European patent specification EP08675666 and EP1243706; It can provide stable support force on the ground at conventional soil, and the soil ground receives the sedimentation of dunnage pressure to produce uniform reaction of bearing, and there is the possibility of lateral sliding hardly in supporting leg.
The Quito, ground in seashore, zone, riverbed is rubble, cobble, compares with the soil ground of routine, has the unbalanced spring load characteristic of multiple spot.Plate dunnage and the area of contact between the basis are little, often are several rubbles or the cobble summits of some coplanes, so the frictional force between dunnage and ground is very little, are easy to produce lateral sliding; In addition, also be forced out, cause bigger counter-force unbalanced, finally all possibly cause using the engineering structure of this supporting leg to collapse, the unstability of engineer equipment and machinery because of the existence of extrusion effect makes under the plate rubble or cobble.
Summary of the invention
The technical problem that the present invention will solve provides a kind of self adaption supporting leg that can adapt to rubble, cobble ground, can solve the problem of traditional supporting leg bad adaptability.
In order to solve the problems of the technologies described above, the present invention includes the supporting leg sleeve, supporting leg sleeve space from end is provided with several first monaurals; Also be provided with the interior bar of retractable in the supporting leg sleeve, interior bar end is provided with several second monaurals, and said supporting leg also comprises and the identical sole plate of the first monaural quantity; The basis is provided with the 3rd monaural, and an end of the 3rd monaural and connecting rod is hinged, and the other end of connecting rod and first monaural are hinged; Also have ears on the sole plate, hinged with second monaural.
Said supporting leg barrel end also is provided with several limiting stoppers, and the connection part of the 3rd monaural and sole plate and the lower extreme point of limiting stopper are on same horizontal plane.
Also be provided with protective equipment between said supporting leg barrel end and the interior bar.
As preferred version, said protective equipment is the tinsel around the bar in being provided with, and tinsel one end is welded on the supporting leg barrel end, and the other end contacts with interior bar.
Technique effect: the present invention can be according to the soft or hard degree of use position soil, and the type of soil is adjusted the start point of sole plate automatically, makes the equipment of using this supporting leg have better stability.

Accompanying drawing 3 uses preceding phase diagram for the present invention;
Accompanying drawing 4 is the user mode figure of the present invention in cobble soil;
Accompanying drawing 5 is the user mode figure of the present invention on rigid ground.
Embodiment
Make supporting leg have good stable property, make in running order supporting leg have certain pressure all around, therefore in landform such as rubble, cobbles; As shown in Figure 1; The present invention includes supporting leg sleeve 1, supporting leg sleeve 1 space from end is provided with several first monaurals 11, also is provided with the interior bar 2 of retractable in the supporting leg sleeve; Interior bar end is provided with several second monaurals 21, and said supporting leg also comprises and the identical sole plate 3 of first monaural, 11 quantity.As shown in Figure 2, sole plate is a surface plate, and is preferably fan-shaped.It is hinged with an end of connecting rod 4 that sole plate 3 is provided with the 3rd monaural 31, the three monaurals 31, and the other end of connecting rod 4 and first monaural 11 are hinged, also have ears 32 on the sole plate 3, and be hinged with second monaural 21.
In order to limit the start point of sole plate, make basic maximum be launched into level, supporting leg sleeve 1 end also is provided with the lower extreme point of connection part and limiting stopper 12 of several limiting stoppers 12, the three monaurals 31 and sole plate 3 on same horizontal plane.
Get into the supporting leg sleeve in order to protect foreign material such as silt, freely stretching of the interior bar of influence also is provided with protective equipment between supporting leg sleeve 1 end and the interior bar 2.As preferred version, said protective equipment is the tinsel 13 around the bar 2 in being provided with, and tinsel 13 1 ends are welded on supporting leg sleeve 1 end, and the other end contacts with interior bar 2.
As shown in Figure 3, the present invention before use, interior bar 2 and sole plate 3 are under the self gravitation effect, interior bar 2 stretches out naturally, sole plate 3 is contraction state.As shown in Figure 4, when supporting leg used in soil such as rubble or cobble, interior bar 2 was under the reaction force on ground; In supporting leg sleeve 1, shrink; Simultaneously sole plate 3 parts are launched, and when soil upwarded pressure to sole plate 3 and uses the equipment of this supporting leg to be equal in weight, supporting leg was in steady state; Owing to received pressure around the sole plate 3, therefore be not easy to slide from the soil side.As shown in Figure 5, when supporting leg used on rigid foundation, sole plate 3 fully was launched into level.
