Portal frame for transferring heavy cargo box

Abstract

The invention relates to the technical field of portal frames, in particular to a portal frame for transferring a heavy cargo box. By arranging a servo motor, a rotating wheel, a belt, a first transmission wheel, a transmission rod, a second transmission wheel and a clamping structure, the heavy cargo box can be conveniently clamped, subsequent transfer is facilitated, and the steps and time required for clamping and fixing the heavy cargo box are reduced. And the situation that the overall transfer speed is low due to the fact that the time for clamping and fixing the heavy cargo box is too long is avoided, and the transfer speed is increased. And by arranging the adjusting structure, lifting adjustment can be conveniently conducted on a lifting plate in the clamping structure, heavy cargo boxes of different sizes can be conveniently clamped and fixed, the situation that different corresponding portal frames are purchased due to the fact that the sizes of the cargo boxes are different is avoided, and economic expenditure is reduced.

Description

technical field [0001] The invention relates to the technical field of gantry frames, in particular to a gantry frame used for transferring heavy cargo boxes. 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 making molds, auto repair factories, mines, civil construction sites and occasions that require lifting. It is commonly used in building construction as material transportation and construction personnel's upper and lower use to realize lifting mechanization. It can reduce manpower, reduce production and operation costs, and improve work efficiency. [0003] When the existing gantry transfers the heavy cargo container, it will use the transfer device to clamp and fix the heavy cargo container. However, when ...

AI Technical Summary

Problems solved by technology

[0003] When the existing gantry transfers the heavy cargo container, it will use the transfer device to clamp and fix the heavy cargo container. However, when clamping and fixing, more steps and time are required, resulting in a slow overall transfer speed , and when transferring heavy containers of different sizes, different transfer devices are required, which increases the overall purchase expenditure, and the load-bearing chains set between the gantry and the transfer device will cause load-bearing chains after long-term transfer of heavy containers. reduced service life
