Stable lifting cantilever crane stand column

Abstract

The invention discloses a stable lifting cantilever crane stand column. The stable lifting cantilever crane stand column comprises a base, fixed plates are fixedly mounted on the four corners of the base, stable movable plates are fixedly mounted in the fixed plates, fixing mechanisms are mounted at one ends of the stable movable plates, each fixing mechanism comprises a fastening screw, a first thread hole, a buffer spring, a fixed block, a limiting cap, an anti-sliding damping gasket, a sliding rod, a limiting plate and a fixed groove, through elastic buffer effects of the buffer springs, vibration of a lifting motor during work can be effectively reduced, use stability of a crane can be improved, handles on the top ends of the fastening screws are rotated to enable the anti-sliding damping gaskets to be stabilized on the ground, a worker can conveniently carry out operation use, work efficiency of the user can be improved, meanwhile, the limiting plates are mounted and placed on thelower surfaces of the fixed blocks through bolts, mounting, fixing, dismounting, maintaining and replacing of the buffer springs and the anti-sliding damping gaskets are facilitated, and the maintaining efficiency of the worker can be improved.

Description

technical field [0001] The invention belongs to the technical field of cranes, and in particular relates to a stable liftable cantilever crane column. Background technique [0002] The pick-up device of the jib crane is swiveled on the end of the arm or on the lifting trolley that can run along the jib. The jib crane that can rotate but cannot pitch is called a jib crane. The jib crane is a small and medium-sized crane. Equipment, unique structure, safe and reliable, high efficiency, energy saving, time-saving, labor-saving, flexible, etc., can be operated freely in three-dimensional space, and is suitable for occasions of segmental distance and intensive transportation. [0003] The height of the column of the existing cantilever crane is mostly fixed, and the usability is not flexible enough. The column of the cantilever crane is mostly driven by a motor, which generates vibration during use, resulting in large noise and poor stability. For this reason, we propose a stable...
