Safe portal frame hoisting equipment with high stability

Abstract

The invention discloses safe portal frame hoisting equipment with high stability. The equipment comprises supporting seats, rotating mechanisms, rotating shafts, first bearings, carrying frames, firstbevel gears, moving mechanisms, lead screws, sliding sleeves, second bearings, supporting plates, supporting rods, connecting sleeves, moving plates, second bevel gears and universal wheels. The equipment has the beneficial effects that the carrying frames are arranged in the supporting seats, the rotating shafts rotate to drive the first bevel gears to better rotate, and the small first bevel gears better drive the large second bevel gears to rotate, so that effort is saved during both ascending and descending of the universal wheels; when a portal frame needs to be moved, the universal wheels are stretched out of the supporting seats, so that the portal frame is moved to a destination more conveniently for use; and the universal wheels are contracted into the supporting seats when not in use, so that the universal wheels are not in contact with the ground, the portal frame is not convenient to move, and the stability of the portal frame is improved.

Description

technical field [0001] The invention relates to a gantry lifting device, in particular to a gantry lifting device with high stability and safety, and belongs to the technical field of gantry lifting devices. Background technique [0002] The gantry is a new type of small lifting gantry developed according to the daily production needs of medium and small factories (companies) for handling equipment, warehouse import and export, lifting and maintenance of heavy equipment and material transportation. It is suitable for manufacturing molds and auto repair factories. , mines, civil construction sites and occasions where lifting is required, it is commonly used as material transportation and construction personnel's upper and lower use in building construction to realize lifting mechanization, which can reduce manpower, reduce production and operation costs, and improve work efficiency. [0003] During the operation of the gantry lifting equipment, universal wheels are provided a...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the gantry lifting equipment, universal wheels are provided at the bottom of the general gantry to facilitate the gantry to move to the destination where it needs to be used. The wheel is in contact with the ground, which makes the gantry not stable enough during hoisting, which affects the hoisting.
