Description
Technical field
The present invention relates to a kind of inclines conveyor belt running zone face replacing options.
Background technology
Unit in charge of construction change coal mine main incline shaft pit shaft adhesive tape zone face operation in, particularly large-scale rubber conveyer, its glue
Band more than meter Chong Da 100kg, transportation lengths are directed to such situation more than 1000 meters, and interspersed, upper well is circulated using new band
The method that old band is reclaimed on mouth vulcanized joint, ground, if small-sized belt feeder, as long as disclosure satisfy that vulcanization in the heapstead of ground
And the condition of advancing equipment, zone face replacing can be carried out using the method, main construction procedure is as follows：
Step 1：Expansion of the virgin rubber with zone face, stack and joint vulcanization；1#, 2#, 3# fixture of the new band of arrangement decentralization；
Step 2：The spillplate of belt feeder head and tail, sweeper, chute, frame are removed；
Step 3：New zone face is introduced, 3# fixtures, new and old zone face drilling, overlap joint are installed；
Step 4：Lap joint crosses unloading, steering, drives roller, clamps 1#, 2# fixture；
Step 5：Start belt feeder, old under band drives new band decentralization；New band glides because deadweight is produced afterwards, drives the new under band in ground
Put, cross aircraft tail cylinder to joint, up a segment distance；Finally start belt feeder, old band drives new band, to the operation of its lap joint
To 2 meters of well head unloading roller rear side；
Step 6：New 4#, 5#, 6# fixture, drawing hoist, tackle pulley, the Locking Device for Hoisting for taking zone face, arrangement vulcanization are stayed after installation
Facility simultaneously carries out last group of vulcanization of joint；
Step 7：Remove vulcanizing deice, remove tackle pulley, after stay zone face the sub-folder of 4#, 5#, 6# tri- have, winch, will wherein one
Platform drawing hoist moved to and installed outside heapstead；The old fixture with both sides at broken belt position and fixation device are installed, in Shang Jing
Break old band at mouthful lower belt surface, after stay the old belt lacing at two ends, withdraw fixture；
Step 8：Belt feeder is rotated forward with minimum speed, and old band is reclaimed on lower belt surface on rear side of unloading roller, and will by drawing hoist
Derived old adhesive tape is drawn to outside heapstead；Old band lower belt surface joint is firm using rope sling binding with new band, and the old band product of tail
When remaining more, a set of easy storage belting is installed between aircraft tail cylinder and belt holder, until after joint has crossed aircraft tail cylinder
Remove again；
Step 9：Recover coal drop, clearing apparatus, spillplate, the frame of frame head and tail；Test running.
This construction method, is primarily present following technical barrier：
（1）Due to inclined shaft length, gradient, the larger odjective cause of the width of zone face, weight, thickness, even if using belt feeder just
Turn to drive new band decentralization, the new existing speed of band decentralization can be gone out and be difficult to control, occur that new band is asynchronous with old tape speed, new band produces product
Remaining situation, or even speed is uncontrolled, new band magnifying slip, extreme danger and loses huge；
（2）When new and old belt lap joint crosses unloading, steering, driving, aircraft tail cylinder, the steel plate in joint location easily causes roller table
The damage of face pad, and due to thickness of belt, steel plate thickness, joint location is easily choked on belt holder, causes belt
Machine is touched the new band zone face of askew or damage.
（3）Originally in decentralization process, speed is mainly old tape running speed to new band；After transferring a segment distance, due to new band
Deadweight, drives belt feeder to rotate forward, and lowering velocity is controlled by fixture and disk brake；Joint crosses the upward segment distance of aircraft tail cylinder
Afterwards, belt feeder is rotated forward and drives new belt lacing up；Above three link, be required to by the elasticity of the upper well head fixture of regulation and
Gap between disk brake brake shoe and flashboard, preferably to control decentralization and the speed uplink of new zone face, speed is too small, skin
Band can not normally start, and startup spot speed is larger, and speed is excessive, and new zone face magnifying slip occurs；When shutting down,
All fixtures and disk brake cooperation are needed, single fixture and disk brake work can cause new zone face to tear.
（4）Before new band is transferred and gone upward in place, the load of belt feeder startup and operation is equivalent to itself adhesive tape weight
Twice causes lap joint to run to ground, it is necessary to consider the motionless new band of belt feeder band occur, completes last group of adhesive tape
Bond stitch vulcanization work；
（5）Lap joint is run to ground unloading roller rear side, need to be before lap joint dismounting, on the new zone face of completion after zone face
Work is stayed, and ensures that the new band of upper zone face will not glide, otherwise will be unable to complete joint vulcanization；During arrangement fixture, new and old belt
Zone face is difficult to put on the ambilateral bolt jackscrew device of folder into " arcs of recesses ".
（6）When old band lower belt surface is blocked, inner wire wire rope core can produce larger impact strength, and the personnel of easily causing receive
The loss of wound or equipment；And after blocking, the belt lacings at two ends need to be drawn or after stay, especially with new with descending old
Belt lacing, after the rope strength stayed it is excessive if cause new band to damage, it is too small if can cause old under band row excessive velocities；
（7）During old band is reclaimed, the big machine speed of service of skin is asynchronous with the speed that drawing hoist reclaims old band, otherwise unloading rolling
The old band cumulative in cylinder side can not be pulled out, and cause old band to twine motionless into the repeated multiple times traction of unloading roller or drawing hoist, be made
The motor damage of car drawing hoist；
（8）During old band is reclaimed, before end connector did not passed through aircraft tail cylinder instantly, the old band cumulative at tail position is more,
Easily cause the old band of tail to twine into inside aircraft tail cylinder, cause normally reclaim old band, due to tail part narrow space, and
Zone face weight is larger, using that cannot be handled well in the artificial short time, even if treatment also simply blocks the old band of cumulative, by both sides
Joint is connected again.Not only the time is more long for do so, and there is also the old situation with cumulative after treatment.This method is not
Can fundamentally Solve problems in construction, and the time is more long, and the off-time caused is more long, and the loss for bringing is bigger.
