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 ofly equip mechanical supporting leg.
Background technique
The engineer equipment such as steel structure bridge, working platform and machinery, in order to improve stability, need a plurality of supporting legs to support conventionally.Supporting leg need to provide enough support stiffnesses, and can have good adaptability to ground.The dunnage of current leg structure mostly is flat type, under load-bearing state, be a rigid plane, as European patent specification EP08675666 and EP1243706 disclose a kind of stabilizing leg and dunnage, it can provide stable support force on the ground at conventional soil, soil is subject to the sedimentation of dunnage pressure to produce uniform reaction of bearing, and supporting leg exists the possibility of lateral sliding hardly.
The ground in seashore, region, riverbed mostly is rubble, cobble, compares with conventional soil, has the unbalanced spring load characteristic of multiple spot.Plate dunnage and the area of contact between basis are little, are often some several coplanar rubbles or cobble summit, so the frictional force between dunnage and ground is very little, are easy to produce lateral sliding; In addition, also because the existence of extrusion effect makes under plate rubble or cobble, be forced out, cause larger counter-force unbalanced, finally all may cause using the engineering structure of this supporting leg to collapse, engineer equipment and mechanical unstability.
Summary of the invention
The technical problem to be solved in the present invention is to provide 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 supporting leg sleeve, supporting leg sleeve space from end is provided with several the first monaurals, is also provided with the interior bar of retractable in supporting leg sleeve, and interior bar end is provided with several the second monaurals, described supporting leg also comprises the sole plate identical with the first monaural quantity, on basis, be provided with the 3rd monaural, one end of the 3rd monaural and connecting rod is hinged, and the other end of connecting rod and the first monaural are hinged, on sole plate, also have ears, hinged with the second monaural.
Described supporting leg barrel end is also provided with several limiting stoppers, and when sole plate is launched into level, the 3rd monaural and the connection part of sole plate and the lower extreme point of limiting stopper are in same level.
Between described supporting leg barrel end and interior bar, be also provided with protective equipment.
As preferred version, described protective equipment is that interior bar tinsel is around set, and tinsel one end is welded on 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 expanded angle of sole plate automatically, makes the equipment of applying this supporting leg have better stability.

Accompanying drawing 1 is plan view of the present invention;
Accompanying drawing 2 is plan view of the present invention;
Accompanying drawing 3 is the phase diagram of the present invention before using;
Accompanying drawing 4 is the use phase diagram of the present invention in cobble soil;
Accompanying drawing 5 is the use phase diagram of the present invention on rigid ground.
Embodiment
Make supporting leg there is good stability in landform such as rubble, cobbles, make in running order supporting leg surrounding there is certain pressure, therefore, as shown in Figure 1, the present invention includes supporting leg sleeve 1, supporting leg sleeve 1 space from end is provided with several the first monaurals 11, is also provided with the interior bar 2 of retractable in supporting leg sleeve, interior bar end is provided with several the second monaurals 21, and described supporting leg also comprises the sole plate 3 identical with the first monaural 11 quantity.As shown in Figure 2, sole plate is surface plate, preferably fan-shaped.On sole plate 3, be provided with the 3rd monaural 31, the three monaurals 31 hinged with one end of connecting rod 4, the other end of connecting rod 4 and the first monaural 11 are hinged, also have ears 32 on sole plate 3, hinged with the second monaural 21.
In order to limit the expanded angle of sole plate, make basic maximum be launched into level, supporting leg sleeve 1 end is also provided with several limiting stoppers 12, and when sole plate is launched into level, the connection part of the 3rd monaural 31 and sole plate 3 and the lower extreme point of limiting stopper 12 are in same level.
In order to protect the foreign material such as silt, enter supporting leg sleeve, in impact, the free-extension of bar, is also provided with protective equipment between supporting leg sleeve 1 end and interior bar 2.As preferred version, described protective equipment is that interior bar 2 tinsel 13 is around set, and tinsel 13 one end are welded on supporting leg sleeve 1 end, and the other end contacts with interior bar 2.
As shown in Figure 3, before use, interior bar 2 and sole plate 3 are under self gravitation effect in the present invention, and interior bar 2 stretches out naturally, and sole plate 3 is contraction state.As shown in Figure 4, when supporting leg is used in the soil such as rubble or cobble, interior bar 2 is under the reaction force on ground, to the interior contraction of supporting leg sleeve 1, simultaneously sole plate 3 parts are launched, and when soil upwards pressure while being equal in weight with the equipment that uses this supporting leg to sole plate 3, supporting leg is in steady state, because sole plate 3 surroundings have been subject to the pressure from soil side, be therefore not easy to slide.As shown in Figure 5, when supporting leg is used in rigid foundation, sole plate 3 is fully launched into level.
