Description
Technical field
The utility model relates to hoisting device, and particularly, the utility model relates to a kind of novel hoisting crane that is used for metallurgy, harbour hoisting operation and uses energy disperser, and it is a kind ofly to combine magnetic force and spring force and have the energy disperser of controlling near switch that said hoisting crane uses energy disperser.
Background technology
At metallurgical, normal crane, dolly and the harbour car stop etc. that use in harbour; Because be vulnerable to bump, safety buffer has been installed in the former capital, absorb because the energy that bump produces with this; The safety of protection lifting equipment is avoided or the generation of the disaster accident of minimizing personnel, mechanical equipment.
At present, the energy disperser that is used for hoisting crane mainly contains polyurethane bumper absorber, water bumper and Magnetic buffer.Also there is the people this to be made development research.For example, application number is that " 02238036.1 ", name are called a kind of representative type polyurethane bumper absorber of relating to of " hoisting crane being used energy disperser ".It is characterized in that fragmentation takes place this energy disperser itself after clashing into, and absorbs impact energy with this.
As everyone knows, the characteristics of polyurethane bumper absorber are: at first, the size of its direction that is impacted can not be excessive, otherwise lose the effect of energy disperser after the bending; Secondly, it is disposable energy disperser, will replace new energy disperser usually after receiving once to clash into, and certainly will cause cost to improve like this.In addition, the polyurethane bumper absorber buffering flexible is relatively poor, generally only is used for accidental or bump smaller applications occasion.
And for example application number is called the water bumper that the utility model patent of " novel hydraulic energy disperser " relates to for " 200520050478.1 " utility model name.This water bumper advantage is, but its relative polyurethane bumper absorber repeated use; The longer dimension of the direction that is impacted, buffering flexible is good.But its deficiency is, water bumper exists cost high, thereby and take place easily to leak to lose the anticollision buffer action, this causes its functional reliability lower.
And for example application number is that " 200720068907.7 ", utility model name are called the water bumper that " Magnetic buffer " utility model patent relates to.This Magnetic buffer is newer technology, and the magnetic force principle through two permanent magnet homopolar-repulsions cushions, and is reusable, does not worry occurring the situation of water bumper leak of liquid, and reliability is better than water bumper.Yet, even adopt said multistage magnetic cushion structure,, when impulsive force is excessive, still have the possibility that bumps between permanent magnet because stroke is shorter, in case collision more energetically takes place, permanent magnet can damage, safety factor still is not very high.
