Safety lifting equipment for ship maintenance with high stability

Abstract

The invention relates to safety lifting equipment for ship maintenance with high stability. The equipment comprises a main beam and two brackets, and further comprises a detecting mechanism and two reinforcing mechanisms; the reinforcing mechanisms comprise driving modules, rollers, second gears, third gears, lead screws, movable blocks, guide rings, connecting wires and lifting hooks; the detecting mechanism comprises a fixed shaft, a rotating disc, a rotating shaft, a guide plate, two support rods, two trigger modules and at least two paddles; and the trigger modules comprise contact switches, slide rods, movable sleeves and springs. In the safety lifting equipment for ship maintenance with high stability, goods can be connected with the brackets through the reinforcing mechanisms, so that the shaking probability of the goods in the lifting process is reduced, and the stability of lifting the goods by a gantry crane is improved; the wind speed can be detected through the detecting mechanism; and when the wind speed reaches a set value, the operation of the gantry crane can be stopped, so that the safety of the gantry crane is improved.

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
