Mechanical lifting appliance special for drum buoy

Abstract

The invention relates to the technical field of navigation marks, in particular to a mechanical lifting appliance special for a drum buoy. The mechanical lifting appliance comprises an annular liftingbeam, universal wheel supporting mechanisms, alignment righting mechanisms and rotary driving devices, wherein the universal wheel supporting mechanisms, the alignment righting mechanisms and the rotary driving devices are arranged on the annular lifting beam; the annular lifting beam is connected with lifting equipment through lifting ropes, and the annular lifting beam sleeves the drum buoy andis connected with lifting rings on the drum buoy through at least two lifting hooks which are uniformly distributed; and at least two universal wheel supporting mechanisms which are evenly distributed are arranged at the bottom of the annular lifting beam, and the annular lifting beam makes contact with the drum buoy through the universal wheel supporting mechanisms and rolls along the drum buoy.According to the mechanical lifting appliance, dangerous operation of manually hanging lifting hooks can be avoided, the risk of direct contact between the navigation mark drum buoy and a ship body is reduced, the ship body and the navigation mark drum buoy are prevented from being damaged manually in the operation process, the construction mechanization operation degree is improved, meanwhile, the labor intensity is relieved, and the safety guarantee of constructors is improved.

Description

technical field [0001] The invention relates to the technical field of navigation aids, in particular to a special mechanized spreader for buoyant drums. Background technique [0002] The maintenance and management of waterways in the shipping industry is an important part of the stable operation and development of the shipping industry. The normal work of navigation buoys, which are important landmarks in ship navigation channels, is an important part of waterway maintenance. The maintenance of navigation marks has three contents, one is to set up navigation marks; the other is to remove navigation marks; the third is to maintain and maintain navigation marks. These three work contents all have the working link of buoy buoy hoisting, that is, lifting the buoy buoy from the ship to the water or lifting the buoy buoy from the water to the deck of the ship. There are two kinds of existing hoisting floating drum operation methods: one is to manually lift the hook of the crane ...

AI Technical Summary

Problems solved by technology

Because it is a water operation, this operation method poses a greater threat to the safety of construction personnel; the other is to use a mechanical method to put the winch wire rope on the bottom of the buoy buoy, and then use the winch to directly drag the buoy buoy. Going on the deck of a ship, in addition to personal safety issues, during the construction process, due to the direct contact and friction between the buoy buoy and the hull, and the swaying of the hull on the water, there is a collision between the buoy buoy and the hull. have relatively large damage
