Abstract
The utility model relates to a lifting device applied to mines. Two sets of lifting devices with a same lifting center line but with different rail gages are arranged in the same inclined lifting shaft; either lifting device has an interlock control that can not operate simultaneously; a middle suspension bridge is arranged at the middle section in the shaft, a shaft-top bridge is arranged at the upper part of the lifting device. Compared with the prior art, the lifting device has the advantages of big lifting capability, less engineering work load and investment, less occupied space, etc.
Description
Technical field
The utility model relates to the bont that uses in a kind of mine.
Background technology:
When existing mine hoisting adopts inclined shaft hoisting, when lifting capacity hour, generally adopt a cover bont.Adopt tube-train hoisting ore, barren rock, material, equipment etc., the personnel selection car promotes personnel.When the ore lifting capacity is big, generally adopt two inclined shafts of major-minor, arrange two cover bonts respectively, promptly main slant adopts a cover skip hoisting plant, is used for lifting ore and barren rock, and subincline is established a cover bont in addition, is used for lifting personnel, material etc.The former reduced investment, quantities is little, but hoisting capacity is little, and reliable degree is low than skip hoisting, and mechanization, degree of automation are low than skip hoisting.Latter's hoisting capacity is big, but quantities is big, and investment is big, and it is big to take industrial place.When lifting capacity is in when medium, when inclined shaft length was longer, when adopting a cover tube-train hoisting, hoisting capacity failed to satisfy requirements, and when adopting two cover bonts, quantities is big, and investment is big, and it is big to take industrial place, complex management.
The utility model content
The utility model provides a kind of scheme of arranging two cover bonts in same lifting inclined shaft in order to overcome the shortcoming of only arranging a cover bont in the same inclined shaft of the prior art.
The technical solution of the utility model is: in the same lifting inclined shaft in mine, establish same lifting line of centers but two cover bonts of different gauges; Two cover bonts are provided with the chain control that bont can not be worked simultaneously; The stage casing suspension bridge is established in each stage casing, down-hole, is provided with the well head suspension bridge on the top of bont.
One cover is carried device for the skip bucket master, undertakes ore deposit, barren rock lifting; The secondary bont of one cover is undertaken lifting tasks such as personnel, equipment, material.In deviated well bore, the elevator road of two cover bonts uses same railway roadbed, and inside is the secondary track that promotes, and the outside is the main track that promotes.The shared steel cable idler pulley of two cover bonts, sleeper etc.The stage casing suspension bridge is established in each stage casing, down-hole, realizes that the interior pair of inclined shaft promotes the elevator road and this stage casing transportation route is got in touch, and when stage casing, down-hole suspension bridge put down, secondary lifting container can enter the parking lot, stage casing in inclined shaft, and when stage casing, down-hole suspension bridge was mentioned, major and minor lifting container all passed through.At slope mouth, the secondary elevator road that promotes is by directly being connected with the secondary transportation route that promotes in ground with vertical curve, the main elevator road that promotes realizes that by the well head suspension bridge inclined shaft is connected with the main elevator road that promotes on the trestle of ground, when the well head suspension bridge rises, secondary lifting container and need the material of lifting, equipment to enter inclined shaft by well head.When the well head suspension bridge put down, main lifting container (skip bucket) can be promoted to ore storage bin top unloading position from inclined shaft shaft bottom loading depot smoothly.Concrete configuration is seen accompanying drawing.
The slope bont that the utility model provides compared with prior art has lifting greatly, and quantities and small investment are taken up an area of advantages such as few.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the birds-eye view of structural representation among Fig. 1.
The specific embodiment:
Promote in the inclined shaft in the ore deposit, Guangxi, be provided with the major-minor bont of not working simultaneously at two covers of same lifting line of centers, promptly main lifting of a cover is the skip bucket single-hoisting, and gauge 1500mm, another set of secondary the lifting are the bunching single-hoisting, gauge 600mm.The slope mouth absolute altitude is 690m, and there are 300m, 350m, three downhole production stage casings of 400m in the down-hole, and ore is transferred by drop shaft, inclined shaft dress ore deposit point absolute altitude is 385m, and well head unloading point absolute altitude is 710m, promotes tiltedly long 769 meters, inclined shaft inclination angle 25 degree, ore is undertaken in skip hoisting and the part barren rock promotes.Lifting means is the single rope of a JK-2.5/20 monotubular cylindrical drum hoist 1, drum diameter φ 2.5m, and steel rope biggest quiet tension allowable and biggest quiet tension difference are 98KN, speed ratio 20, adapted JR1512-8 type alternating current dynamo 2, power 630Kw, rated speed of rotation 740rpm, maximum lift speed is 4.8m/s.Promoting steel cable is 6 Δs (19) φ 31mm triangular strand wire rope 3, and steel cable nominal tensile strength is 1680MPa, and the breaking force of rope summation is 729.6KN.Lifting container is 5m
3Rear-unloading type inclined shaft skip 4, normal load is 10t, hoisting capacity is 95t/h.The pair of inclined shaft promotes the lifting tasks such as mine producers, material, equipment of undertaking.Secondary lifting means is a JK-2/20 type list rope mining hoist 5, joins JR148-8 type alternating current dynamo 6, and power of motor is 240Kw, voltage 6000V, rated speed of rotation 735rpm, maximum lift speed 3.7m/s, promoting steel cable biggest quiet tension and biggest quiet tension difference is 58.84KN.Promote steel cable 7 and select 6 Δs (19) φ 26mm triangular strand wire rope for use, steel cable nominal tensile strength is 1680MPa.Steel cable rupture pull force summation is 498KN.During the lifting personnel, promote two XRC15-6/6 type people cars 8 at every turn, each people Che Chengren 15 people, during the jacking equipment material, weight is no more than 5000kg.
Working process
Major-minor two cover bonts do not use simultaneously, when the skip bucket master carries device and starts working, secondary hoisting cable is packed up, well head suspension bridge 9 puts down, stage casing, down-hole suspension bridge is mentioned, and main electromotor is removed chain, and the skip bucket that is locked on the well head unloading trestle is transferred to dress ore deposit, dress station, ore deposit, shaft bottom, behind the dress ore deposit, be promoted to the well head ore storage bin and ore in the skip bucket unloaded by dump rail 10.When secondary bont is started working, empty skip bucket to be parked on the well head unloading trestle, the well head suspension bridge is mentioned, the main electromotor locking, need the stage casing suspension bridge 11 of work to put down the down-hole, the secondary lifting started working, and realizes promoting parking lot intersegmental lifting and transferring to the underground work from well head is secondary.
