Abstract

This utility model relates to field of mechanical technique, it is specially a kind of supporting leg, including pedestal and expansion plate, two ends, the left and right symmetry activity of described pedestal is plugged with expansion plate, and bottom expansion plate, it is fixedly connected with improved mat, two parallel supports vertically it are provided with on described pedestal, and one end of support and hydraulic telescopic device connects, the fixing connection of the other end of hydraulic telescopic device and one end of contiguous block, and the other end fixed operating sleeve cylinder of contiguous block, described sleeve is actively socketed on machinery major axis, described contiguous block is plugged with pin, this supporting leg simple in construction, it is be combined with each other by the structure adding hydraulic telescopic device and expansion plate, during to mechanical support, by the extension of expansion plate, increase the contact area on pedestal and ground, reduce pressure protection road surface.Being symmetrical arranged of the connecting rod simultaneously used, have employed the stable principle of geometric triangulation shape, and what therefore the design of this structure can protect ground can increase again the stability to frame for movement.

Description

A kind of supporting leg
Technical field
This utility model relates to field of mechanical technique, is specially a kind of supporting leg.
Background technology
Development along with industry, increasing machinery needs a stable supporting construction, wherein, semitrailer is to apply a kind of means of transport in modern transportation industry, semitrailer its front end in motion can be connected with tractor to be supported by and draw dragging, can hang de-to the front end of semitrailer and tractor when not travelling, in order to support the front end of semitrailer after de-extension, the bottom of semitrailer front end is often provided with supporter of semi-trailer.The most conventional supporter of semi-trailer is bi-directional variable speed, built-in feed screw nut and gear-box, it is connected with the supporting plate on semitrailer entirely through bolt and it needs to strengthen gusset or inclined bearing is strengthened, realize promoting by crank and supporting arrangement internal transmission during lifting.Even if being also suspended on below vehicle frame when existing supporting arrangement does not uses, it has not been convenient to shrink, and the more important thing is that stability is inadequate, bigger to the destructiveness on ground.To this end, it is proposed that a kind of supporting leg.
Utility model content
The purpose of this utility model is to provide a kind of supporting leg, with the problem solving to propose in above-mentioned background technology.This utility model has the advantage that can increase again the stability to frame for movement on protection ground.
For achieving the above object, this utility model following technical scheme of offer: a kind of supporting leg, including pedestal and expansion plate, two ends, the left and right symmetry activity of described pedestal is plugged with expansion plate, and bottom expansion plate, it is fixedly connected with improved mat, two parallel supports vertically it are provided with on described pedestal, and one end of support and hydraulic telescopic device connects, the fixing connection of the other end of hydraulic telescopic device and one end of contiguous block, and the other end fixed operating sleeve cylinder of contiguous block, described sleeve is actively socketed on machinery major axis, described contiguous block is plugged with pin, and one end of pin and two symmetrically arranged connecting rods is rotationally connected, each described connecting rod is all rotatably connected on expansion plate by hinge away from one end of pin.
Preferably, described hydraulic telescopic device includes back-moving spring and hydraulic stem, and back-moving spring is socketed on hydraulic stem.
Preferably, described pedestal and expansion plate are cuboid, and pedestal is hollow structure.
Compared with prior art, the beneficial effects of the utility model are: this supporting leg simple in construction, are be combined with each other by the structure adding hydraulic telescopic device and expansion plate; during to mechanical support; by the extension of expansion plate, increase the contact area on pedestal and ground, reduce pressure protection road surface.Being symmetrical arranged of the connecting rod simultaneously used, have employed the stable principle of geometric triangulation shape, and what therefore the design of this structure can protect ground can increase again the stability to frame for movement.
Accompanying drawing explanation
Fig. 1 is this utility model structural front view;
Fig. 2 is this utility model structure top view.
In figure: 1 pedestal, 2 expansion plates, 3 supports, 4 hydraulic telescopic devices, 5 contiguous blocks, 6 connecting rods, 7 sleeves, 8 machinery major axis, 9 improved mats.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-2,A kind of technical scheme of this utility model offer: a kind of supporting leg,Including pedestal 1 and expansion plate 2,Two ends, the left and right symmetry activity of described pedestal 1 is plugged with expansion plate 2,And bottom expansion plate 2, it is fixedly connected with improved mat 9,Two parallel supports 3 vertically it are provided with on described pedestal 1,And one end of support 3 and hydraulic telescopic device 4 connects,The fixing connection of the other end of hydraulic telescopic device 4 and one end of contiguous block 5,And the other end fixed operating sleeve cylinder 7 of contiguous block 5,Described sleeve 7 is actively socketed on machinery major axis 8,Described contiguous block 5 is plugged with pin,And one end of pin and two symmetrically arranged connecting rods 6 is rotationally connected,Each described connecting rod 6 is all rotatably connected on expansion plate 2 by hinge away from one end of pin,Described hydraulic telescopic device 4 includes back-moving spring and hydraulic stem,And back-moving spring is socketed on hydraulic stem,Described pedestal 1 and expansion plate 2 are cuboid,And pedestal 1 is hollow structure.
Operation principle: by sleeve 7 be socketed in plant equipment per se with major axis 8 on, then operator can regulate the height of plant equipment by hydraulic telescopic device 4, when running into plant equipment and being heavier, have only to extract out expansion plate 2 from pedestal 1 inner chamber, just can increase the whole mechanism contact area to ground, being symmetrical arranged of the connecting rod 6 simultaneously used, connecting rod 6, triangle is formed between hydraulic telescopic device 4 and pedestal 1, have employed the stable principle of geometric triangulation shape, that can protect ground can increase again the stability to frame for movement.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
