A high-stability safe hoisting device for ship maintenance

Abstract

The invention relates to a high-stability safe hoisting device for ship maintenance, which includes a main girder and two brackets, and also includes a detection mechanism and two reinforcement mechanisms, and the reinforcement mechanism includes a driving assembly, a roller, and a second gear , a third gear, a screw, a moving block, a guide ring, a connecting line and a hook, and the detection mechanism includes a fixed shaft, a turntable, a rotating shaft, a guide plate, two support rods, two trigger assemblies and at least two paddles leaf, the trigger assembly includes a contact switch, a slide bar, a moving sleeve and a spring. In the high-stability safety-type hoisting equipment used for ship maintenance, the cargo and the bracket can be connected together through a reinforcement mechanism, which reduces the The probability of the goods shaking during the hoisting process improves the stability of the gantry crane hoisting goods. The wind speed can be detected through the detection mechanism. When the wind speed reaches the set value, the gantry crane can be controlled to stop running, which improves the safety of the gantry crane. .

Description

technical field [0001] The invention relates to the field of ship maintenance equipment, in particular to a highly stable and safe hoisting device for ship maintenance. Background technique [0002] Gantry crane is a kind of deformation of bridge crane, also called gantry crane, mainly used for loading and unloading operations of outdoor goods yard, material yard cargo and bulk cargo. Gantry crane has high site utilization rate, large operation range, wide adaptability, It has strong versatility and is widely used in port freight yards. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have overhanging cantilever beams. . [0003] As a kind of hoisting equipment, the gantry crane plays an important role in the process of ship maintenance. In the process of hoisting goods with the gantry crane of the prior art, the goods are prone to shake under th...

Problems solved by technology

[0003] As a kind of hoisting equipment, the gantry crane plays an important role in the process of ship maintenance. In the process of hoisting goods with the gantry crane of the prior art, the goods are prone to shake under the action of inertia, which reduces the stability of the goods hoisted by the gantry crane. Not only that, if the gantry crane of the prior art is operated in a windy weather, the strong wind will cause the goods to shake, which not only reduces the accuracy of the gantry crane for hoisting goods, but also reduces the safety of the gantry crane
