Problems solved by technology

[0002] In the prior art, most of the lifting legs are implemented in the form of hydraulic cylinders. Due to internal leakage at the piston inside the hydraulic cylinder, the legs of the hydraulic cylinder are slightly retracted, and the legs cannot be rigidly self-locked for a long time. It will affect the equipment that needs to be lifted for a long time, and even cause unsafe equipment and other safety accidents, which cannot meet the use requirements of the equipment

Abstract

The invention discloses an adjustable and self-locking supporting leg mechanism for lifting equipment. The adjustable and self-locking supporting leg mechanism comprises a support on the upper portion, a base on the lower portion and a support position adjusting mechanism for adjusting the relative axial position of the support and the base, and the support is connected with the base through the support position adjusting mechanism. The support comprises a seat body, and the upper end of the seat body is provided with a supporting plate for connecting a lifted object with the support. The support position adjusting mechanism comprises a screw with a thread at the upper end, a locking nut and a connecting block on the lower portion, the lower end of the screw is connected with the connecting block, and the upper portion of the screw is matched with the locking nut. A vertical connecting plate is hinged to the base through a first pin shaft. A positioning connecting plate is arranged at the lower end of the support, and the locking nut is connected with the positioning connecting plate. The adjustable and self-locking supporting leg mechanism with the structure has a self-locking function, the supporting leg does not retract, and the problem of retraction caused by long-time lifting is thoroughly solved. The adjustable and self-locking supporting leg mechanism is simple and reliable in structure and low in manufacturing cost, is hardly affected by the external environment, and can adapt to different use environments.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to an adjustable and self-locking outrigger mechanism for lifting equipment. Background technique [0002] In the prior art, most of the lifting legs are implemented in the form of hydraulic cylinders. Due to internal leakage at the piston inside the hydraulic cylinder, the legs of the hydraulic cylinder are slightly retracted, and the legs cannot be rigidly self-locked for a long time. It will affect the equipment that needs to be lifted for a long time, and even cause unsafe equipment and other safety accidents, which cannot meet the use requirements of the equipment. Contents of the invention [0003] The present invention aims at overcoming the above-mentioned shortcomings in the prior art, and provides an adjustable and self-locking outrigger mechanism for lifting equipment. The structure of the present invention has a self-locking function. After being installed o...
