Problems solved by technology

When the rail-mounted container gantry crane is in the peak loading and unloading conditions of stacking and taking containers, the running mechanism of the trolley is prone to failure. When the trolley mechanism breaks down, it cannot run immediately, and the trolley mechanism may stay at any position on the cantilever track of the yard bridge. If it is not timely, it will cause great economic losses to the port terminal. During the maintenance process of the existing maintenance cranes, most of them can lift the maintenance parts to the required height and cannot be installed at a suitable angle. The imported heavy parts cannot be lifted directly through maintenance, and manual assistance is required to adjust the angle, which is more complicated and difficult to adjust, which has a great impact on maintenance work

Abstract

The invention relates to the field of cranes, in particular to a maintenance crane and a rail type container portal crane. According to the maintenance crane provided in the embodiment, a lifting device enables a connecting device used for connecting workpieces to ascend or descend to the specified position height, a first adjusting part is rotationally connected to a connecting part, and the first adjusting part can change the rotating angle of the workpieces; and the first adjusting part is rotationally connected with a second adjusting part, and the inclination angle of the workpieces can be conveniently adjusted to a proper angle. According to the maintenance crane, the workpiece angle can be effectively converted into the proper angle, manual rotating is not needed, the work difficulty is greatly reduced, and maintenance can be conveniently carried out in time. The rail type container portal crane comprises the above maintenance crane, and therefore the rail type container portalcrane also has the above beneficial effects.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a maintenance crane and a rail-type container gantry crane. Background technique [0002] With the continuous changes in the transportation market and the improvement of container production technology, the future market demand for containers will also become complex and diverse. The rail-mounted container gantry crane is one of many port cranes. It is suitable for long-term operations in fixed places due to the use of mains electricity, no pollution, and sufficient energy. It is an essential equipment for port cargo handling and transportation. [0003] Rail-mounted container gantry cranes are mainly used for container loading, unloading, handling and stacking in container railway transfer yards and large container storage yards. When the rail-mounted container gantry crane is in the peak loading and unloading conditions of stacking and taking containers, the running mechanism of the trol...
