Description
Technical field
The present invention relates to the method for lifting underground large-tonnage bridge crane, specifically a kind of especially big elevator caves of interior shaft
The installation method of room large-tonnage bridge crane.
Background technique
It is long for the coal mine hoist chamber compared with big cross section, such as San-Shan-Dao Gold Mine mine down-hole elevator chamber
18.7m, width 14.1m, high 15.65m, large-tonnage bridge crane installation difficulty are very big.Driving installation is wanted in elevator chamber
It is carried out simultaneously with shaft equipment installation, stable vehicles and sinking headframe cannot all be removed, therefore install operating space and be restricted.Separately
On the one hand, chamber top walking dolly and top plate spacing are smaller, such as the San-Shan-Dao Gold Mine mine down-hole elevator chamber,
Chamber top walking dolly and top plate spacing only have 2 meters, further limit working space.And the electronic bridge of large-tonnage 60t/10t
Formula crane, be self-possessed 38.976t, and tonnage is big；Underground digs chamber and has poured completion, can not implement well using large-tonnage truck crane
Lower lifting.
Having a kind of design in the prior art is to realize large-tonnage bridge by alternately lifting in elevator cave indoor construction grillage
Formula crane is in the especially big indoor lifting of elevator cave.Although this design can be completed big using elevator chamber inner space
Tonnage bridge crane is deposited in the especially big indoor lifting of elevator cave, but due to needing repeated disassembled and assembled grillage and hydraulic jack
In the defect that equipment consumption is big and great in constructing amount, construction is cumbersome.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of especially big elevator chamber large-tonnage overhead traveling cranes of interior shaft
The installation method of machine realizes large-tonnage bridge crane in especially big elevator chamber by installing main electric chain hoist upper end
Convenient lifting.
Technical scheme is as follows:
A kind of installation method of the especially big elevator chamber large-tonnage bridge crane of interior shaft, it is characterised in that including following step
It is rapid:
Step 1: drilling construction, closing well head:
1), in the surface construction drill chamber of elevator chamber；
2), in the top plate of elevator chamber to the stress load center construction drill between drilling machine chamber；It is required that elevator chamber
Top plate to drilling machine chamber bottom surface spacing be not less than 12m；
3), pit shaft is closed in the junction position of elevator chamber and guide wheel chamber；
Bis- Walk: construction drill chamber locks rope device:
1), in drilling machine chamber wall side, several anchor poles of constructing, by anchor pole outer end and drilling manganese steel plate welding, as lifting
The lock rope card of wirerope the top；
2) lock rope beam, is set up in the surface of the drilling, the fixed guide wheel carrier on lock rope beam is installed in guiding wheel carrier upper end
Directive wheel, and wirerope board is installed on lock rope beam；
3) elevator chamber, is set to through drilling decentralization steel cable and connects main electric chain hoist, it will be on main electric chain hoist
It mentions to chain sling upper hook and elevator chamber top plate and being adjacent to, wirerope is then fixed on lock rope beam by the wirerope board
On, wirerope is located at the part above the board and is fixed on the lock rope card around upper end after directive wheel；
Step 3: lifting operation:
1) it, is arrived first by the assembled driving steel beam lifting to crownblock beam in an elevator drum side with the drawing of secondary electric chain hoist
Roller side；
2) it, is drawn on another assembled driving steel beam lifting to crownblock beam again with secondary electric chain hoist to elevator motor side；
3) walking dolly, is finally lifted by crane, stopping when plane has certain interval on walking dolly distance from bottom driving beam orbit is hung to
The crane beam of two sides is drawn to walking dolly lower part with secondary electric chain hoist, transfers walking dolly after connecting by lifting.
Preferably, confining bed construction method described in the step 3) of the first step: will be as the I-steel of girder and as pair
The channel steel of beam is welded into mutually roof beam structure, and checkered steel plate is welded on roof beam structure as bottom plate, is then laid with sand as buffering, fire prevention
Layer.
Preferably, the method for lock rope beam is set up in the step 2 of bis- Walk: pouring pre-buried raw muscle hook in drilling machine chamber bottom surface
Two I-steel intervals are welded on raw muscle hook plate by steel plate.
The present invention is constructed in especially big elevator chamber using drilling machine chamber, guide hole, installation lock rope device, by main electric chain hoist
It is mounted on the top at elevator chamber stress load center.On the one hand lifting space has effectively been expanded, on the other hand
The stress of main electric chain hoist is decomposed into drilling machine machine cave, is more advantageous to protection elevator chamber.Major technique advantage is: with
Metallic mineral resources are continually developed, and earth superficial resource gradually decreases, and tends to be depleted, therefore metal mine exploitation is just
Constantly develop to deep mining, and scale continues to increase.At present China's metal mine mining depth be more than km more than only
There is a few, and it is smaller to exploit scale.In this context, the present invention provides a kind of especially big chamber crane installations in underground
New technology solves underground large-scale hoister chamber vault lifting insufficient space, and according to traditional grillage, alternately lifting installation consumes
When, effort, consumptive material the drawbacks of.
The present invention is mounted with Lock with double safety guard rope device in drilling chamber, further improves overall security and reliable
Property.
Specific embodiment
Method of the invention is further illustrated combined with specific embodiments below.
The blind combined shaft mineshaft diameter 5.5m in San-Shan-Dao Gold Mine mine, the elevation of well -600m, shaft bottom absolute altitude -1240m.Most
It is low to serve the middle section -1240m.Combined shaft hole top signal chamber is set in -600m.Elevator chamber is located at -537.3m absolute altitude, chamber
