Container portal crane with double trolleys, and working method thereof

Abstract

The invention discloses a container portal crane with double trolleys, and a working method thereof. The problems that a traditional container portal crane is generally provided with only one trolleyas a component for position and direction regulation and consequently the position of the container portal crane can only be regulated front and back or right and left but can not be regulated horizontally, longitudinally and vertically simultaneously, and the potential safety hazard that containers are liable to shake during lifting due to heavy weight, or even fall off can be solved. The container portal crane comprises a gantry, and a supporting mechanism located at the bottom of the gantry, and an upper frame on the top of the gantry, and the top of the upper frame is provided with a regulating mechanism; the outer wall of one side of the gantry is provided with an escalator connected with the side wall of the upper frame, and the outer wall of the other side of the gantry is fixedly provided with a power supply and a PLC; the top of the gantry is provided with the upper frame of which the edge is wrapped by a protective frame, and the inner walls of the both sides of two support legs at the bottom of the gantry are each provided with a sliding chute; and a baseplate is arranged at the bottoms of the support legs.

Description

Technical field [0001] The invention relates to a container door machine, in particular to a container door machine with double trolleys and a working method thereof. Background technique [0002] Container gantry cranes, also known as rail-mounted container gantry cranes, are mainly used for container loading, unloading, handling and stacking in container railway transfer yards and large container storage and transportation yards. [0003] However, the existing container gantry cranes still have certain defects when they are used. Generally, there is only one trolley as a component for position adjustment and direction adjustment, so that it can only adjust the position of the front and rear or left and right directions, and does not have the ability to simultaneously perform horizontal, vertical and vertical. It can adjust the position in all directions in the straight direction, and because of the heavy weight of the container, it is easy to shake or even fall off during lifting...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a container door operator with double trolleys and its working method, which can solve the problem that when the traditional container door operator is used, generally only one trolley is used as a component for position adjustment and direction adjustment, so that it can only perform front and rear or direction adjustment. The position adjustment in the left and right directions does not have all-round position adjustment in the horizontal, vertical and vertical directions at the same time, and due to the heavy weight of the container, it is easy to shake or even fall off when lifting
