Portable crane jib maintenance platform

Abstract

The invention discloses a portable crane jib maintenance platform which comprises a shelving platform for shelving a jib, and a crane head shelving hole is formed in the shelving platform; two baffles are fixedly arranged on the shelving platform and are respectively arranged on two sides of the crane head shelving hole; a cushion block for supporting the suspension arm is also arranged on the shelving platform; a supporting frame is fixedly arranged at the bottom of the shelving platform, the supporting frame comprises four stand columns and a plurality of supporting rods, and the supporting rods are fixedly arranged among the stand columns; the portable crane jib maintenance platform further comprises a container foot device fixedly arranged on the deck, the container foot device comprises a plurality of container foot bases, and the four stand columns are inserted into the container foot bases respectively. According to the platform, the requirement for daily maintenance of a crane can be met, the maintenance platform can be portable, meanwhile, the space requirement for loading large-size goods on the deck face of a ship is met, and the economical efficiency of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a portable crane arm maintenance platform. Background technique [0002] Cranes are commonly used lifting equipment on ships, especially for some ports with weak infrastructure, they must be equipped with Cranes to complete loading and unloading operations. Crane cranes are frequently used equipment, requiring staff to frequently check and maintain the hooks, wire ropes, booms, etc. Generally, in order to have a sufficient lifting height for the cargo, the distance between the boom of the crane and the deck surface is relatively large, and the general portable straight ladder cannot meet the maintenance tasks. Therefore, the traditional design method is to install a ladder between the boom and the deck surface. Fixed maintenance platform, the platform support column is firmly welded on the deck surface. [0003] For the current fixed maintenance platform, it is necessary to desig...

AI Technical Summary

Problems solved by technology

[0004] At present, the fixed maintenance platform of the crane arm causes the deck surface to be divided into several smaller areas by the main body of the maintenance platform and the cylinder body of the crane. For ships transporting large cargo, the layout of the fixed maintenance platform is severely restricted. The size of the cargo that can be transported is limited, and the scope of adaptation of the ship is limited, which is not conducive to the improvement of the economic efficiency of the ship

The crane is set at the center of the ship. If the fixed boom maintenance platform is set on the side of the ship, this design will affect part of the view of the bridge

For example, the boom of the crane has a self-locking function, but the boom is not equipped with a fixed bracket for the crane, which brings difficulties to the inspection and maintenance of the self-locking crane.
