Abstract

A kind of hoistable platform supporting leg, comprise fixed supporting leg, movable supporting legs, hydraulic cylinder and feet, one end of described fixed supporting leg is fixed on hoistable platform underframe, the upper end of the other end and described movable supporting legs is hinged, the end of described hydraulic cylinder is hinged on described fixed supporting leg, be relatively set with two gathering sills in described movable supporting legs both sides, the piston rod front end of described hydraulic cylinder is provided with transverse axis, and the two ends of described transverse axis lay respectively in the gathering sill of movable supporting legs both sides; Described feet is connected to the lower end of movable supporting legs by universal joint. The invention solves the problem that adopts long stroke hydraulic cylinder and increase cost and take up room; Can make face tilt angle, feet base area rotate, thereby implement with inclined plane, prevent the security incident that hoistable platform shakiness causes, and feet adopts latch to be connected to feet bottom, can change as required the feet with anti-slop serrations.

Description

Hoistable platform supporting leg
Technical field
The present invention relates to a kind of for the auxiliary equipment on hoistable platform, a kind of hoistable platform supporting leg specifically.
Background technology
Hoistable platform is a kind of Multifunctional hoisting loading mechanization equipment, and it makes work high above the ground efficiency higher, and safety more ensures. At present; hoistable platform is divided into fixed and portable; in use; often can meet slope or slope road; the feet of common hoistable platform supporting leg can only contact completely with ground on horizontal plane, on the inclined-plane of angle that is at a slight tilt, can not implement, and has so just caused the unstable of hoistable platform; may slide, cause security incident. And, for the movable leg bottom that ensures hoistable platform can fall to the ground, the hydraulic cylinder that all adopts stroke to grow between hoistable platform supporting leg, not only cost is high, and it is large to take up room.
Summary of the invention
The shortcoming existing in order to overcome above-mentioned prior art, the object of the present invention is to provide one on sloping floor, to implement, and the hoistable platform supporting leg that adopts little stroke hydraulic cylinder to get final product.
In order to address the above problem, the present invention is by the following technical solutions: a kind of hoistable platform supporting leg, comprise fixed supporting leg, movable supporting legs, hydraulic cylinder and feet, one end of described fixed supporting leg is fixed on hoistable platform underframe, the upper end of the other end and described movable supporting legs is hinged, the end of described hydraulic cylinder is hinged on described fixed supporting leg, it is characterized in that, be relatively set with gathering sill in described movable supporting legs both sides, the piston rod front end of described hydraulic cylinder is provided with transverse axis, and the two ends of described transverse axis lay respectively in the gathering sill of movable supporting legs both sides; Described feet is connected to the lower end of movable supporting legs by universal joint.
Preferably, the upper end of described universal joint is fixed on the lower end of described movable supporting legs by bearing pin.
Preferably, be provided with anti-slop serrations in the bottom surface of described feet.
The invention has the beneficial effects as follows: it is provided with gathering sill on movable supporting legs, solved the problem that adopts long stroke hydraulic cylinder and increase cost and take up room; Its feet is arranged on movable supporting legs bottom by universal joint, can make face tilt angle, feet base area rotate, thereby implement with inclined plane, prevent the security incident that hoistable platform shakiness causes, and, feet adopts latch to be connected to feet bottom, can change as required the feet with anti-slop serrations.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is described further:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is feet of the present invention and gimbal structure schematic diagram.
In figure, 1 fixed supporting leg, 2 movable supporting legs, 21 gathering sills, 3 hydraulic cylinders, 31 transverse axis, 4 feets, 41 anti-slop serrations, 5 underframe, 6 universal joints, 61 pin shaft holes, 7 bearing pins.
Detailed description of the invention
As depicted in figs. 1 and 2, specific embodiments of the invention comprise fixed supporting leg 1, movable supporting legs 2, hydraulic cylinder 3 and feet 4.
One end of described fixed supporting leg 2 is fixed on hoistable platform underframe 5, and the upper end of the other end and described movable supporting legs 2 is hinged, and the end of described hydraulic cylinder 3 is hinged on described fixed supporting leg 1. be relatively set with two gathering sills 21 in described movable supporting legs 2 both sides, gathering sill 21 is arc, its upper end is bent upwards, the piston rod front end of described hydraulic cylinder 3 is provided with transverse axis 31, the two ends of described transverse axis 31 lay respectively in the gathering sill 21 of movable supporting legs 2 both sides, after the piston rod of hydraulic cylinder struts, transverse axis 31 is positioned at the front end (position as shown in Figure 1) of gathering sill, after piston rod is packed up, transverse axis 31 is positioned at the end of gathering sill 21, by the guide effect of gathering sill 21, make piston rod upward sliding in the time pushing ahead, in the time that stretching out unit length, piston rod make movable supporting legs 2 move down distance maximum.
In order to ensure that feet 4 can implement on inclined plane, described feet 4 is connected to the lower end of movable supporting legs 2 by universal joint 6, and universal joint 6 preferably adopts universal ball joint. In the present embodiment, the upper end of described universal joint 6 is welded to connect piece, is provided with pin shaft hole 61 on contiguous block, universal joint 6 is fixed on the lower end of described movable supporting legs 2 by bearing pin 7, the lower end of universal joint 6 is welded on feet 4, like this, can change as required feet 4.
In order to prevent that feet 4 from sliding on inclined plane, be provided with anti-slop serrations 41 in the bottom surface of described feet 4, anti-slop serrations 41 is particularly evident in the effect on dirt road ground. If do not need to use the feet 4 with anti-slop serrations, can change a not feet 4 with anti-slop serrations.
The above is the preferred embodiment of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications are also regarded as protection scope of the present invention.
