Description
Technical field
The present invention relates to a kind of tuningout tensioning method of belt of belt conveyor, particularly one kind are used for coal mine fully-mechanized mining work
Make the method that face gate trough-belt conveyer carries out tuningout tensioning by the travelling dolly of tuningout tensioning to conveyer belt.
Technical background
Ribbon conveyer is indispensable extremely important main equipment in underground coal mine coal production, particularly conveys
Bandwidth in 1200cm, conveying capacity position in 1600t/h, belt speed in 300cm/s, fed distance 1000m ribbon conveyer especially
Seem particularly significant.But the ribbon conveyer for this width conveyer belt, large-tonnage, distance is continuously running for a long time
During, aging due to conveyer belt, the accumulation of material is uneven, the reason such as abrasion of machinery, inevitably causes
Skidding, deviation phenomenon, skidding can make cylinder contact friction with conveyer belt, and temperature raises, and adhesive tape ignites；Sideslip can make outside material
Spread, reduce conevying efficiency, the abrasion heating of conveyer belt corner, or even cause fire, have a strong impact on the safety in production of mine.Therefore,
When ribbon conveyer skidding, sideslip in running, to adjust belt conveying if there are corresponding tensioning tuningout method
The running status of machine, can be effectively prevented from the generation of above-mentioned accident it is ensured that Safety of Coal Mine Production is runed in order.
The tuningout tensioning method of existing Belt Conveyors Underground Coal Mine conveyer belt is mainly installed in storage belting frame
The method of screw thread adjusting deviation device is had to finely tune bend pulley established angle, when belt deflection, the bearing block of bend pulley is in spiral shell
Under the effect of stricture of vagina adjusting deviation device, there is relative movement in both sides, makes the small angle deflection that cylinder produces 2 °～4 °, unloaded slow in conveyer belt
Speed carries out manual deviation rectification method in the case of running.Under the humidity working environment of down-hole, screw thread easily becomes rusty dead and leads the method
Cause disabler, simultaneously uneven with the operating of the high speed distance of ribbon conveyer, solid accumulation, frequently result in conveyer belt
Overall sideslip.
The invention of a kind of " belt tension and tuningout device and its using method " disclosed in existing Publication No. cn1962218a
Patent；Belt tension and tuningout device disclosed in this patent and its using method are not suitable for the wide conveyer belt of underground coal mine, big ton
Position, the ribbon conveyer of distance are rectified a deviation and tensioning, yet there are no the belt about wide conveyer belt large-tonnage, distance
Conveyer belt correction tensioning method.
