Description

The compound bont of vertical shaft

Technical field

The utility model is the compound bont of a kind of vertical shaft, the particularly bont of mine hoisting personnel and material.

Background technology

The bont of existing mine hoisting personnel and material includes gig, lifting container and head sheave and steel rope, and its lifting container has cage, skip bucket and cage---array configuration of skip bucket etc.Gig has single wire winding type double-drum hoist and the wheeled gig of multi-rope friction, and the side that lifting container has is a bob-weight.Lifting container is fixed on the gig by steel rope, head sheave, and perhaps lifting container links to each other with the opposite side lifting container by steel rope, friction wheel.When gig started, lifting container rose, and another lifting container descends simultaneously.Otherwise, lifting container descends then, and another lifting container rises, this its hoisting capacity of bont 50% shared by the quality of lifting container own, and in mining design, once determine, thereby hoisting capacity is also determined thereupon, but the mine all is faced with mining depth and strengthens year by year, and productive capacity increases and necessarily requires to strengthen the problem of hoisting capacity.

In order to address this problem, the common practice is to open up vertical shaft again, but its investment is big, long in time limit, and the way that the mine that also has takes to change lifting means increases hoisting capacity, but because lifting means costs an arm and a leg, not only investment is big, and influences ordinary production.

Publish China Construction Industry Press in August, 1988 " mining design handbook the 4th volume discloses a kind of three head sheave elevator system, its concrete structure is to add steel cable again to link to each other between two lifting containers, this root steel rope directly strides across the 3rd head sheave without gig and is connected to each other, purpose is exactly in order to balance the deadweight of lifting container mutually, to make the lifting container deadweight not enter gig.But this three head sheaves promote owing to the decline along with lifting container of the rope capacity of balance two lifting containers increases, the rising of lifting container and reducing, therefore this root steel rope changes in the weight of every side, this variation is certain to be reacted to gig and gets on, lifting container is when the shaft bottom, and the deadweight of opposite side lifting container will be balanced some more, if lifting container is on top, then the deadweight meeting of opposite side lifting container is balanced less, and this upwards promotes loaded vehicle is disadvantageous.And because the difference of steel rope creep elongation amount, the tension force between three steel ropes is difficult for regulating suitably.If the steel rope of bob-weight side is broken at well head simultaneously, then because the weight of bob-weight is affirmed the lifting container greater than opposite side, at this moment bob-weight except own to falling in the shaft bottom, because it links to each other with the lifting container of opposite side by balance rope, therefore, the lifting container of opposite side just can be balanced steel rope and haul rapid rising, thereby produces serious accident.

Goal of the invention

The purpose of this utility model is to avoid the weak point of above-mentioned prior art, make the lifting container deadweight not take or take less the loading of hoisting cable terminal and provide a kind of, reduce lifting container taking to hoisting capacity, make the lifting container quality of minimizing be converted into the lifting capacity weight, thereby increase hoisting capacity, increase the compound bont that promotes the degree of depth, this plant investment is few, power consumption is low, safety factor is big, does not influence ordinary production.

Summary of the invention

The purpose of this utility model is achieved in that and is promoting the original bob-weight of bob-weight compartment (stable equilibrium hammer) top, increase a unsteady bob-weight, by two balance head ropes, two track adjusting wheels that derrick increases newly and the lifting container of opposite side link to each other, and increase by two tail ropes in unsteady bob-weight and lifting container bottom and link to each other.Float bob-weight above the stable equilibrium hammer, the two maintains certain distance, in normal lifting process, can not come in contact, the bob-weight weight of floating all the time can the balance opposite side the lifting container deadweight, and between unsteady bob-weight and stable equilibrium hammer, being equipped with shock absorber, when preventing emergency braking, fierce collision takes place in the two.The bob-weight that floats slides on stable equilibrium hammer slideway, and the stable equilibrium hammer moves on the vertical shaft cage guide.When stable equilibrium hammer hoisting cable took place by disconnected the rope, the stable equilibrium hammer was understood self and is fallen, and can not drive the bob-weight that floats and fall.In order to make the two head rope stress equalizations of bob-weight that float, on two head ropes, one end lifting container, be provided with adjusting rope device.Said stable equilibrium hammer also can be a lifting container.

The invention advantage

The utility model compared with prior art has following advantage:

1, because the fixing invalid load in the lifting process all is balanced, only remaining capacity weight (ore) and movable invalid load (mine car) are moved, and therefore can alleviate the quality of elevator system motion parts greatly.The weight that outstanding more a bit is is balanced does not enter in the working process of gig and goes, and just is balanced outside gig, therefore in the whole service process, can adopt original gig, and hoisting capacity increases considerably.

2, the compound bont of vertical shaft because lifting container has main rope and three wire rope suspensionings of head rope, has double insurance to lifting container except that lifting container is had the general various safety performances, free accident of cage crashing can not take place, and is therefore, safe and reliable.

3, this compound bont small investment, the unit power consumption amount is low, because the increase facility is few, is ground construction again, and is therefore easy to install, and the construction time is short, does not influence ordinary production.
