Abstract

The invention relates to a crane capable of stabilizing a ship. A truss type lifting arm of a caterpillar crane body is changed from one into two through modifications, one main lifting hook is changed into two main lifting hooks, a sliding way is welded on the upper portion of the portion between the two arms through T-type steel, a winding engine and a pulley are installed on the two arms, the pulley is provided with the second main lifting hook which can move front and back, a lifting electromagnet control cabinet is installed on the crane, and then two rectangular lifting electromagnets, electromagnet carrying supports and two lifting hook balance weight iron blocks are manufactured; when the crane is used, the lifting electromagnets with the electromagnet carrying supports and the lifting hook balance weight iron blocks are lifted by the crane, two cranes form a group, according to the width of a ship body of the lifted ship and the parking position of the lifted ship, the cranes conduct amplitude variation and enable the second main lifting hooks to slide, the four lifting hooks of the two cranes accurately find the positions to enable the lifting electromagnets to get close to the outer side of the ship body of the lifted ship under the condition that lifting of the lifted ship is not influenced, after balance of the lifted ship is well adjusted, and the four lifting electromagnets are powered on at the same time to tightly suck the lifted ship. According to the crane, the lifted ship can be assisted to resist stormy waves higher than six to seven grades in the sea at least.

Description

A kind of energy is stablized the hoisting crane of boats and ships

Technical field:

The invention belongs to mechanical hoisting industry, this energy is stablized the hoisting crane of boats and ships, is to be converted by crawler crane, is a kind of posture arm hoisting crane that spreads out with 2 main hoisting hooks.

Background technology:

The present invention relates to a kind of energy and stablize the hoisting crane of boats and ships, the hoisting crane that this energy is stablized boats and ships is to be converted by crawler crane process, increased the function that can stablize boats and ships, and the original lifting performance of crawler crane is constant after repacking.The hoisting crane that this energy is stablized boats and ships is by double truss-like arm and be arranged on winch on arm, coaster, slideway and 2 main hoisting hooks, 2 suspension hook counterweight iron blocks and lifting electromagnet, electromagnet bracket and lifting electromagnet control box are formed.All over the world, large cargo or the larger bulk shipping major part of amount are all by seat transport, the handling of the port and pier goods of various places are all to be completed by crane ship, world's meteorology and sea situation show: marine climate is complicated and changeable, high tide ebb drop is larger, general two weeks is one-period, respectively have every day 2 times in theory, flood tide ebb is subject to typhoon, monsoon, the impacts such as flood, more than 50% time crane ship is slowed down and is stopped hanging, region, the North Sea crane ship lifting time is less than the half that can utilize the time, only account for 34% left and right that can utilize the time in the time of East China Sea region hoisting heavy, these results show, what sea beat hull caused hangs thing swing, roll and pitch motion to crane ship has tremendous influence, because crane ship can be accepted to have wasted plenty of time and money in the process of sea situation waiting for, crane ship and the owner of cargo's economic loss is very serious.How to reduce the risk that offshore lifting operation is attacked by stormy waves, reduce and lose because being subject to stormy waves to attack the work holdup causing, strive for more lifting operation time, impel the progress of marine lifting safety method, fast, economic, effective and safe and reliable lifting operation, be very important for advancing marine resources development.

Summary of the invention:

As everyone knows, cargo ship and the lifting boats and ships of domestic and international each harbour some stops of port at present, in the time of handling goods, all in the time waiting for that sea situation and weather allow, just dare lifting, although the tonnage of these crane ships is larger, generally all in 2500-5000 ton left and right, the hoisting crane tonnage of some boats and ships has exceeded 10,000 tons, but in lifting operation way, running into wave attacks, they can stop lifting operation at once, avoid causing danger, abroad some carry after the huge cargo ship arrival harbour alongside of weight-lifting equipment, dare not lift by crane easily, observing after sea situation and weather, before lifting, for boats and ships more stable, they will install a huge floating drum at profile, to alleviate the swing of hull in the time lifting, it is a very difficult thing that floating drum is installed, floating drum weighs 115 tons, the steel square arm that floating drum is connected with hull weighs 40 tons, a floating drum is only installed with regard to more than 2 hours consuming time, stablize lifting boats and ships by the method for this installation floating drum, the maximum sea wind that can resist 3-4 level left and right, if when sea wind reaches 5-6 level, they can stop lifting operation at once.How to solve at harbour, harbour stops the cargo ship of alongside and the risk that lifting boats and ships are attacked by stormy waves in the time of handling goods, the technical scheme that the technical matters that the present invention solves adopts is: with the 700-1000 tonne of crawler crane through repacking, because the length of boom of 700-1000 tonne of crawler crane can reach 140 meters of left and right, this hoisting crane one through repacking has 2 main hoisting hooks, the 1st main hoisting hook is the original main hoisting hook of hoisting crane, the 2nd main hoisting hook is the main hoisting hook that can move forward and backward on arm after repacking, in when repacking in order to make the 2nd main hoisting hook move forward and backward, first repack the posture arm that spreads out of crawler crane into arm structure by single arm structure, above in the middle of both arms, weld a slideway with T-steel, then winch and coaster are installed on arm, it is to lean on the winch on arm to control that coaster moves forward and backward on slideway, the 2nd main hoisting hook is installed on coaster.A lifting electromagnet control box is installed simultaneously on crawler crane, after hoisting crane has been reequiped, make 2 oblong lifting electromagnets and 2 oblong electromagnet brackets again, finally make 2 square suspension hook counterweight iron blocks, the weight of each suspension hook counterweight iron block is minimum more than 20 tons.First 2 lifting electromagnets are installed on 2 electromagnet brackets in use, again 2 suspension hook counterweight iron blocks are connected respectively on 2 electromagnet brackets, the other end of 2 electromagnet brackets is hung on 2 main hoisting hooks of hoisting crane, and hoisting crane lifting object on 2 suspension hooks in the time of lifting is lifting electromagnet, electromagnet bracket, suspension hook counterweight iron block successively.Every 2 crawler cranes are one group, block 4 points of crane ship, the position of berthing according to the width of crane ship hull and crane ship, crawler crane is through luffing and the 2nd the main hoisting hook that slide, in the situation that not affecting crane ship lifting, after 4 suspension hook capturing positions of 2 crawler cranes, lifting electromagnet is leaned against to crane ship hull outside, after treating that crane ship self mixes up balance, 4 lifting electromagnets are switched on simultaneously, tightly hold crane ship, the suction of each lifting electromagnet can reach tens tons, suction is extremely strong, even if spraying paint, hull do not affect suction yet.Under the weight of suspension hook counterweight iron block helps, the low energy of this method helps the marine stormy waves of crane ship opposing 6-7 level, after lifting electromagnet energising to human body without any damage, almost do not feel.The method of this stable boats and ships, safe and reliable, simple, quick, practical.The crane arm of this structure also can be arranged on ocean platform crane or other hoisting crane and use.Do not find in the world the product the same with the present invention by State Intellectual Property Office's retrieved web.
