A hoisting device with anti-collision function for ship maintenance

Abstract

The invention relates to a hoisting device with anti-collision function for ship maintenance, which includes a main girder, a hoisting device and two brackets, and also includes a protection mechanism and four anti-collision mechanisms, and the anti-collision mechanism includes a second support rod , a moving rod, two first support rods, two moving sleeves, two springs, two contacts and two trigger assemblies, the protection mechanism includes a guide rail, a moving base, a driving assembly, a rotating shaft, a roller, The connecting wire and the carabiner, the trigger assembly includes a support sleeve and a connecting rod, and the drive assembly includes a motor, a first gear and a second gear. In the hoisting equipment with anti-collision function used for ship maintenance, through the protection The mechanism connects the operator with the main beam, which improves the safety of the operator and the practicability of the gantry crane. Under the action of the anti-collision mechanism, the probability of collision of the gantry crane is reduced, and the probability of damage to the gantry crane is reduced. , improving the safety of the gantry crane.

Description

technical field [0001] The invention relates to the field of ship maintenance equipment, in particular to hoisting equipment with anti-collision function 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. The gantry crane of the prior art generally moves along the pre-laid track on the ground. During the mo...

[0003] As a kind of hoisting equipment, the gantry crane plays an important role in the process of ship maintenance. The gantry crane of the prior art generally moves along the pre-laid track on the ground. During the moving process of the gantry crane, if there is debris placed on the track, It will cause collision between the gantry crane and debris, which will increase the probability of damage to the gantry crane. Not only that, when the gantry crane fails, the operator needs to overhaul the gantry crane. During the maintenance process, the operator needs to carry out high-altitude operations , if there are no effective protective measures, it will reduce the safety of operators working at heights and reduce the practicability of gantry cranes
