Description
The utility model relates to a kind of pit gear, and specifically a kind of many ropes hang tail rope balancing list rope and twine driving type lift for mine.
The vertical shaft mining elevator is that contact is aboveground, the throat thoroughfare of down-hole, and it is undertaking the vertical-lift task of ore, barren rock, personnel, material and facility.The selection influence factor of vertical shaft mining elevator is a lot, such as mine capacity, transportation mode, mine ventilation, specifically promote task (main shaft, auxiliary shaft or mixed lifting), the developing degree of depth etc.Therefore the vertical shaft mining elevator generally must can be determined after relatively through multi-scheme.The operation of the selection of vertical shaft mining elevator and vertical shaft mining elevator is again two key factors in the scheme deterministic process.This also is to carry out the focus that all kinds of elevator system are inquired at applicable elements and economy research, lifting theory, lifting means intensity and the dynam of China for many years.
The vertical shaft mining elevator of prior art mainly divides single rope winding hoisting and multi-rope friction hoisting two big classes.Multi-rope friction hoisting is divided into the tower friction winding and the friction winding of landing again.Single rope twines to promote and is used for the mine of the degree of depth less than 600m more, and multi-rope friction hoisting is used for the mine of degree of depth 300m～1400m.External mine-laying formula only is used for the mine of well depth greater than 1400m.Because of China mine overwhelming majority in 1000m, shaft hoisting limit is in single rope winding hoisting and two kinds of forms of multi-rope friction hoisting in the native land.
It is fairly simple with elevator work principle that single rope twines shaft mine, exactly an end of steel wire rope fixed and is wrapped on the cylinder of elevator, and other end pile warp headgear pulley hangs hoisting container.Rope outlet direction difference (upper right rope stretching, lower-left rope stretching) when utilizing cylinder to rotate like this is wrapped with steel cable or unclasp.To finish the work that promotes or transfer container.
The range of use of single-rope hoisting is restricted under the deep-well condition, this is because when the big terminal loading of deep-well, in order to bear the weight of terminal loading and steel rope itself, the diameter of steel cable often requires very big, and cross large diameter steel rope except on making and using all the inconvenience, also the flexure stress that will be produced when satisfying steel rope pile warp cylinder can not be excessive, for certain load-carrying capacity of keeping steel cable with directly strengthen gig diameter and width service life.The upgrading of elevator specification not only increases equipment investment, and the main frame equivalent mass obviously strengthens.Single-rope hoisting does not have big pulling force difference and the main frame equivalent mass that the tail rope balance produces increases this two key factors, causes the obvious increasing of power draw.Therefore huge equipment and heavy-duty motor all are uneconomic to maintenance management and operation.
Multi-rope friction hoisting and single rope twine promote different and are that steel rope is not to be wrapped on the cylinder but to take to be placed on the capstan, and replace a thick steel cable with several than thin steel rope (being even number 2,4,6,8 arranges), lifting container is suspended on the two ends of steel rope.When working, bearing by elevator that the steel wire rope of pulling force is inevitable to be pressed on the friction lining and to produce certain frictional force with certain normal pressure.When the driven by motor capstan rotates, drive steel wire rope along with capstan rotates by the frictional force of the friction lining on leading between steel wire rope like this, thereby realized the lifting of container and transfer.
Tower multi-rope friction vertical shaft mining elevator is that tower multi-rope friction rope is the top layer that a whole set of lifting means is installed in headframe with landing the difference of multirope friction winder, advantage is not limited by the mine landform, simplified industrial place, steel rope is not subjected to the influence of sleety weather, but the headframe cost is very high, and the construction period is oversize.The multi-rope friction vertical shaft mining elevator that lands be with hoist installation on the face of land, two group the restrict head sheave of Winding rope on derrick articulates with container respectively mutually.Although reduced initial investment and duration, it is more serious that the steel cable outdoor layout is affected by sleety weather, and non-skid property obviously reduces, and invar Sheng Chord length is shaken and increase rope spacing.Although therefore multi-rope friction vertical shaft mining elevator utilizes several thin steel cables to replace a thick steel cable job, has solved the excessive problem of capstan diameter.But the compressive strength etc. that exists steel cable in the lifting process to slide, promote steel cable intensity and capstan friction lining is the problem that need overcome always.
Although the shortcoming of singly restricting winding hoisting and multi-rope friction hoisting extensive use at home and abroad in sum but all having limitation and being difficult for overcoming.Especially stop at previous level does not significantly improve in weight of equipment with aspect cutting down the consumption of energy always.It is exactly in order to seek even more ideal shaft hoisting mode that people are devoted to promote Study on Theory, and purpose is to reduce investment and energy savings to greatest extent under technical feasibility, reliable, the prerequisite being convenient to manage as far as possible.
The purpose of this utility model provide a kind of simple in structure, cost is low, many ropes of small investment, short construction period hang tail rope balancing list ropes and twine the drive-type mining elevators.
The purpose of this utility model realizes in the following manner, many ropes hang tail rope balancing list ropes twine driving type lift for mines by single rope winding hoisting machine, winding cage, balance tail rope, tail rope hanger, the head sheave of restricting, the stabilizer of restricting more more, promote head rope, the anti-formula tension force full automatic balance suspension arrangement etc. turned round partly forms.Wherein symmetrical even number steel cable is overlapped on many rope stabilizers, two ends articulate with the suspension arrangement on hoisting container top respectively, middle steel cable one end is hung joint with the anti-twisting equipment on hoisting container top respectively, the other end respectively the restrict middle grooving of head sheave of pile warp upper strata stabilizer and lower floor (also can adopt when the diameter of top stabilizer satisfies two hoisting container centre-to-centre spacing on many rope stabilizers tops and establish two single rope head sheaves more, remove many ropes head sheave of lower floor, form three days wheel constructions.) be fixed on single rope winding gig, promptly the right side is an overlap, a left side is a underlap.
It is with multi-rope friction hoisting and the organic combination of single rope winding hoisting by the anti-formula tension force full automatic balance suspension arrangement of turning round that many ropes of the present utility model hang tail rope balancing list rope winding driving type lift for mine, make the head rope of domestic and international multi-rope friction hoisting become the odd number suspension by the even number suspension, namely Winding rope is 1,3,5,7,9 layout.Integrate the advantage of multi-rope friction hoisting and single rope winding hoisting, form a kind of new lifting device.Its operation principle is: when single rope winding hoisting machine rotates under motor-driven, the different steel wire rope of the two rope outlet directions respectively middle grooving of many ropes head sheave of the stabilizer on pile warp derrick upper strata and lower floor and the anti-twisting structure in the middle of the hoisting container upper suspension device articulates, and forms the lifting of container and transfers.This moment is because the effect of tension force full automaticity balancing device makes odd number root steel cable stressed in full accord.And the torsion that middle steel cable occurs in lifting process is balanced out by anti-twisting equipment.The torsion that the steel cable that the both sides even number is arranged produces is offset because of sth. made by twisting about it itself, thereby guarantees not produce the additional friction of container cage shoe and cage guide.

Embodiment:
It is very simple and convenient that many ropes of the present utility model hang its processing and fabricating of tail rope balancing list rope winding driving type lift for mine, and processing and manufacturing gets final product shown in the by specification accompanying drawing.Single rope winding hoisting machine and multi-rope hoist are general mining equipment.The use of tension force autobalance frame is by the hydraulic cylinder of adjusting in the equalization of strain frame that joins with every steel cable steel cable to be strained, then by pipeline with the oil circuit of hydraulic cylinder in each equalization of strain frame and together, the rate of tension of each steel cable of flow equilibrium by hydraulic oil in the hydraulic cylinder.
Many ropes of the present utility model hang the anti-characteristics of turning round single rope winding hoisting device of formula Full-automatic tension balance of tail rope balancing:
The shortcoming that this lifting device has overcome multi-rope friction hoisting and single rope winding hoisting forms a kind of more satisfactory lifting device.Therefore have following tangible characteristics:
1. reduce capital expenditure significantly: can not fall because of several key factors of lifting means type selecting have restricted specification of equipment that (span that rules require can not break through, because rules are lessons written in blood.) and make specification of equipment very big sometimes.Adopt the full cloth of Maximum static pull force of this device whole system to drop on the stabilizer on derrick top, 2～4 specifications can fall in the single rope winding hoisting machine that therefore mates, if its affiliated facility is taken into account, and the minimum reduction by 40～65% of the investment in comparable situation.
2. obviously reduced working expenditure: the main frame specification reduces, the total equivalent mass of system obviously reduces, the anti-effect of turning round tension force full automaticity balancing device descends system's pulling force difference at double, can reduce 25～45% from static(al) system and power system comprehensive analyses (under the comparable situation) matched power of reaching a conclusion.
3. problem that can not the multilayer rope woolding when having solved single rope winding hoisting and carrying the people: the single rope of rules regulation winding hoisting mustn't twine two-layer when promoting personnel, this lifting device has been eliminated steel cable because of the effect (hydraulic pressure transient equilibrium) of tension force full automatic balance and has been twined the two-layer vibration of steel cable when excessive, and can twine multilayer.
4. remove the anti-fall device that single rope winding hoisting must be established:
Single rope winding hoisting that rules regulations is carried people drop system (many liters promote and can not establish) of must setting up defences.This system hangs with odd number root steel, adds that the restrict brakes of stabilizer of derrick top forms the multi rope winding operation more, thereby the drop system of need not setting up defences.
5. improved the ability of taping the latent power of old mine:
The mine that China's twentieth century built up about the 60 to 70's (substantially all be single rope winding hoisting machine) all exists to be extended and to the problem of deep mining, but lifting means all can also use, but behind expansion scale or the deepening, original equipment all can't meet the demands.The demonstration of comprehensively calculating warp adopts this lifting device to promote the degree of depth in the situation of output increase by 50～80% can increase by 1.5～2.0 times.
6. directly shorten the mine construction duration: the duration is to consider in the time of must adopting tower friction winding in the situation to the restriction of mine construction orographic condition.Adopt many ropes stabilizer on this lifting device derrick top directly to replace tower multi-rope friction hoisting, derrick can be in the place processing away from well head, and To Construction of Silo is unaffected, has greatly shortened the capital construction duration.
7. solved and landed the impact of multi-rope friction hoisting climate: be on ground with hoist installation owing to land multi-rope friction hoisting, outside the long part of its Winding rope De Chord is exposed to, the sleet sky directly makes the ice of rainwater and knot take to upward leading and the frictional force between steel cable and liner is reduced, and forms the skidding impact and promotes effect.Adopting new lifting device is to twine the impact that the long part of Qi Chord of rope stretching ， is not subjected to sleety weather at all with single rope.Thereby improved the running state of whole elevator system.
8. the anti-formula full automaticity equalization of strain of turning round has been eliminated single rope and is twined and promote that steel cable reverses and the container cage shoe that causes and the friction between the cage guide:
Be in the friction loading process owing to carve in the cage shoe of container and the cage guide in the lifting process, not only damage the operation that container and cage guide also affect elevator main frame and motor simultaneously, cause system's operation steadily not reach easily and have an accident.Adopt new bont its anti-structure directly to eliminate the twisting resistance that steel cable produces in the lifting process, make the elevator system running steadily and container cage shoe and cage guide change less.
Five. society and economic benefit: China continues to use the lifting means manufacturing technology and the technology arrangement of the Soviet Union in the early days of foundation in decades always, though improve in some place, than the old type spectrum of equipment raising is arranged.But the phenomenon of low load with strong power exists in newly-built and enlarging mine always, is in the high energy consumption state sometimes decades, and this development and technological advance with society is incompatible.Therefore say and adopt new bont can change the looks and the present situation in all mines of China, and improved the safety and the level of management that promote.
The economic benefit of this bont can following example illustrate: changing the line of production as the Shandong Province, (300,000 tons/year colliery is because of the mineral resources exhaustion in the mine, several thousand people go home, now change the line of production and prepare to establish 500,000 tons/year iron ore) the nearly 500m of iron ore vertical depth that will build, need two shaft developments, when adopting single rope to twine the rope machine by normal design, main shaft needs the double-cylinder single rope of φ 4.50m to twine gig, matched power N=1250KW.Auxiliary shaft needs φ 3.5m double-cylinder single rope to twine gig, matched power N=800KW.If adopt multirope friction winder, main shaft needs the four-rope friction winder of φ 2.8, matched power N=1000KW, and auxiliary shaft needs the four-rope friction winder matched power N=600KW of φ 2.25.
As adopt many ropes to hang tail rope balancing list rope winding driving type lift for mine, main shaft only needs the single double-cylinder single rope winding hoisting of φ 2.5m machine all can, matched power N=500KW, auxiliary shaft with the single double-cylinder single rope winding hoisting of φ 2.0m machine all can, matched power is N=200KW.The φ 2.5m double-cylinder single rope winding hoisting machine of this former usefulness in ore deposit, and can be directly used in Newly-built mine behind the φ 2.0m monotubular list rope winding hoisting machine overhauling, not only reduce significantly capital expenditure and alleviate the contradiction of mine financial difficulty, matched power also reduces greatly simultaneously, has directly reduced operating cost.
Can both by this consideration, save immeasurable investment will for country based on the mine that upper routine China is newly-built.If include the reorganization and expansion mine range of consideration in, the investment of saving and to reduce energy consumption be imponderable.
Vast territory and abundant resources in China, and rich in mineral resources has large quantities of ore deposits to start every year, and have thousands of mine to produce for many years since the establishment of the nation, all faces expansion scale and deepening.All be difficult to reach designing requirement by designing before original lifting means.And adopt new lifting device that original system is transformed a little just and can be met the demands.
The superficial part mineral resources verified the 1950's of China have approached exhaustedly according to statistics, and later mine is all developed to the deep.Though adopt original lifting device can satisfy the capital construction requirement the investment and energy consumption also be surprising.Simultaneously thousands of old mine original vertical shaft and equipment when deep mining is all scrapped too unfortunately, has not only wasted fund, and personnel placement also is a problem.Continue and adopt new lifting device can do well in a short period of time to produce.Therefore say that this device is to have excellent popularization to be worth and prospect.
