Stable supporting leg of crane

Abstract

The invention discloses a stable supporting leg of a crane. The stable supporting leg comprises a twist rod, wherein the upper end of the twist rod is connected with a retractable end of a jack; the stable supporting leg of the crane is simple in structure; an outer bottom wall of a supporting box is in contact with the ground; the twist rod moves downwards through controlling the jack on the crane, so that the movable rod is obliquely inserted into the ground under the limiting effect of a sleeve, and the crane is stabilized; furthermore, the crane is stabilized; when the twist rod moves downwards, a drill bit is inserted into soil, and a supporting box suffers from relatively great resistance caused by the soil; the falling speed of the twist rod is greater than that of a roller; the roller rotates, and a steel wire rope is wound on the roller; first pistons move to get close to each other, so that a piston rod stretches out towards the horizontal direction and is inserted into the soil, so that the crane is stabilized.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a stable support foot for a crane. Background technique [0002] Construction machinery is an important part of the equipment industry. In a nutshell, all the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects are called construction machinery. Cranes are commonly used lifting equipment. When the existing cranes lift heavy objects, they extend the jack on the side wall of the crane to support the ground, and then fix the position of the crane. Because the contact area between the jack and the ground is small, it is difficult to To allow the crane to support on the complex ground environment, for this purpose, a stable support foot for the crane is proposed.
