Walking spider crane for ship use

Abstract

The invention relates to a walking spider crane for ship use. The walking spider crane comprises a frame. Two sets of wheels are arranged at the bottom of the frame. One set of wheels is connected with a drive motor, and the other set of wheels is connected with a hydraulic steering device. A storage battery set is arranged in the frame. A pump station and a hoisting device are arranged at the top of the frame. An electric hydraulic control operation unit is arranged at the tail end of the frame. Hydraulic supporting legs are arranged at the four corners of the top of the frame respectively and comprise steering knuckles, supporting leg oil cylinders, steering supporting legs and telescopic supporting legs. The steering knuckles are arranged on the frame and rotate in the horizontal direction. The tail ends of the steering supporting legs are hinged to the steering knuckles. The two ends of the supporting leg oil cylinders are hinged to the steering knuckles and the head ends of the steering supporting legs respectively. The telescopic supporting legs comprise fixed segments and telescopic segments. The tail ends of the fixed segments are hinged to the head ends of the steering supporting legs. The tail ends of the telescopic segments are inserted in the head ends of the fixed segments and fixed through pins. Strong magnetic suction cups are hinged to the head ends of the telescopic segments.

Description

technical field

[0001] The invention relates to a marine crane, in particular to a walking spider crane used in ships. Background technique

[0002] Marine walking spider crane is a kind of engineering equipment used for lifting on ships. Ordinary car chassis cranes have superior driving performance and driving performance, and can facilitate the conversion of work sites, but the equipment has a large size and a large weight. The road adaptability to the job site is low. Considering the narrow space on the ship and the limitation of the ship's deck conditions, the marine walking spider crane adopts electric drive axle, hydraulic steering axle, hydraulic telescopic luffing boom and extendable and adjustable telescopic support. The legs can rotate 360 ​​degrees during the operation, and they are small in size, light in weight, high in work efficiency, and can work continuously in a small space. Contents of the invention
