Description
Technical field
The present invention relates to a kind of remodeling method of shaft hoisting system, changes more particularly to a kind of tower bright shaft hoisting
The remodeling method of ground formula lifting, can be in the tower bright shaft hoisting system of the underground mine such as steel, coloured, gold, chemical industry, coal not
Stop production and applied in transforming.
Background technology
Bright shaft hoisting is widely used in the underground mine of the industry such as steel, coloured, gold, chemical industry, coal, wherein restrict more
Friction pulley is lifted, and can be divided into tower and console mode and be lifted two kinds.
In China, there are many mines lifted using frictional geared, because the elevator selected originally is less than normal, in pit shaft
After extension, original elevator can not meet safety requirements；Some mines, because original design hoisting power is less than normal, with life
The development of production, need to increase hoisting power, then need to change bigger skip bucket or single decker cage is replaced with into two-deck(er) cage.More than
Situation, all refer to that increasing elevator need to be changed, the problem of promoting system.But existing technical method is utilized, if will
Elevator is changed, then needs pit shaft stopping using a very long time, first removes existing equipment, then placing installation base again
Plinth beam, installation elevator, 1 year at least, at most more than 1 year off-time.But reality is, most mine, its
Lifting system is the project of primary importance in mine, it is impossible to which stop production transformation for a long time, and therefore, the bright few renewals of vertical shaft multi rope winding change
Situation about making, most of is all that cylinder of newly digging well is updated transformation, causes investment substantial increase.
Chinese patent ZL201410189166.2 discloses a kind of frictional geared lifting interior shaft lifting system and not stopped production
Remodeling method, its technical scheme are：A new lifting system elevator chamber is newly tunneled on former elevator chamber opposite or side,
A new lifting system rope race is newly tunneled from new lifting system elevator chamber and goes to 4-8m positions to interior shaft top, and new
New lifting system head sheave chamber is tunneled on lifting system rope race end；On new lifting system head sheave chamber bottom plate rock pillar, utilize
The rock drill down new lifting system steel wire rope cord hole of Drilling；By steel wire rope by new lifting system rope race, new lifting system head sheave,
New lifting system steel wire rope cord hole is connected with hoisting container, and former elevator is stopped using, it is achieved thereby that frictional geared is lifted
The non-stop production reformation of interior shaft lifting system.But this method is not suitable for tower bright shaft hoisting and changes not stopping production for console mode lifting
Transformation.
The content of the invention
The purpose of the present invention is aiming at current tower bright shaft hoisting system because shaft stretch causes original lifting to set
It is standby less than normal and need to change elevator to increase hoisting power, but the problem of can not stop production for a long time, and a kind of tower is provided
The bright shaft hoisting of formula changes the non-stop production reformation method of console mode lifting.
To realize the above-mentioned purpose of the present invention, a kind of tower bright shaft hoisting of the present invention changes not stopping production for console mode lifting and changed
Make method and use following technical scheme：
In former headframe building, former elevator, former directive wheel, former electric-control system and hoisting container, pedestrian stair, electricity are installed
Ladder, former driving, non-stop production reformation is carried out using following steps：
1）Between the bright vertical shaft normal production period for needing to transform, the L distances in former headframe building periphery, a new well of newly constructing
High building framework, described new headframe building frame height after former headframe building roof, are continuing up construction until dividing above
Not Xing Cheng console mode lifting need lower sheave wheel platform beam, upper head sheave landing beam, head sheave maintenance hoisting beam totally three layers of Vierendeel girder be
Only, head sheave is installed on upper head sheave landing beam, head sheave under being installed on lower sheave wheel platform beam.
2）Between the bright vertical shaft normal production period for needing to transform, M distances, new headframe building framework one in former headframe building periphery
Side, ore deposit orientation is unloaded according to existing hoisting container or goes out car orientation, arrangement, newly-built console mode lifting are lifted according to console mode
Computer room；New elevator is installed in console mode winding houses, new electric-control system is arranged on console mode winding houses side.
Described L distances using new headframe building frame foundation will not to former headframe building basis produce destroy and also convenient construction as
Principle, it is the smaller the better, and all directions L can take different value.
Described M distances are to design specific determination.
3）The steel wire rope being connected according to the new elevator calculated with upper head sheave, lower head sheave needs the position passed through,
Oblique cutting openings are opened up on the roof, exterior wall and part storey floors in former headframe building；According to upper head sheave, lower head sheave and lifting
The steel wire rope of container connection needs the position passed through, and two vertical cutting openings are opened up on the roof in former headframe building；It is oblique to cut
Mouth, vertical cutting openings are cut open as new lifting system steel-cable channel.
4）New console mode elevator and new electric-control system, on head sheave and lower head sheave after all installation, debugging are good, utilize inspection
Repair or holiday time, former elevator, former directive wheel removed into displacement, new lifting system steel wire rope is connected with hoisting container,
The completion in this way, lifting system renovates, former elevator are stopped using.
It is described in improvement and installation, it is necessary to pedestrian stair is continued up extension and is installed to prolong pedestrian stair position
On prolong pedestrian stair and be tiltedly mounted between lower sheave wheel platform beam and upper head sheave landing beam.Two sheave wheel platforms are laid into steel plate
And carry out safe fence.
Optionally decide whether the elevator installed in former headframe building movement being installed on upper head sheave landing beam, be changed into moving up
Elevator.
To make structure stress more reasonable, described new headframe building framework is combined by frame column, Vierendeel girder and tie-beam
Form, frame column is vertically mounted on ground, and Vierendeel girder is horizontally arranged on frame column, tie-beam be horizontally arranged at frame column with
Between former headframe building.If construction does not influence existing production, tie-beam can also cross the framework in former headframe building and opposite side
Beam connects.
Described new headframe building framework can also close into headframe building form, and L, M size are unlimited.Described new headframe building framework
Post, the quantity of Vierendeel girder and tie-beam, height, position, specification, size etc. are unlimited, and the sequencing of part retrofit work is unlimited.
The non-stop production reformation method that a kind of tower bright shaft hoisting of the present invention changes console mode lifting uses above technical scheme
Afterwards, have the advantages that：The bright vertical shaft frictional geared normally produced can be lifted in the case where bright vertical shaft does not stop production
Machine is changed, so as to carry out upgrading to lifting system.
Main advantages of the present invention：Avoid mine and change lifting means because the bright vertical shaft of lifting can not stop production, and have to
Separately new pick lifting pit shaft, or lifting system renovates to stop production for a long time influences the situation of mine economic profit, it is economical
Positive effect.
