Scraper conveyor run before checking and runtime considerations and requirements
1 run before the inspection
Scraper conveyor running before the first roadway support for workplace conduct an inspection. Meanwhile, to check whether there are obstacles within the roadway, downpipe on
whether someone, check the cable hanging is intact, the motor starts properly. In addition, the response body, organs, tail
A focus on several key components checked.food metal detector
The inspection body shall start to finish piecewise checked. Check the contents are: chain link, linking rings, scraper is installed properly; chute lap is stable, no card
chain, scraper; a seamless coal and other issues. Head checks, mainly to check whether the coupling position correct; clearance is
Meet the requirements (typically 3-5mm); each part of the fixed base is solid; gear oil is appropriate (high gear oil contacts the fourth appropriate); gear wear is excessive
and so on.
Check the tail, the tail is the main inspection machines have coal, waste rock, wood and other debris; whether there is water phenomenon, if there must be cleaned. Also check
the tail is firmly installed, with or without protection devices, the location is put right and so on.Pharmaceutical metal detector
After the inspection, make sure everything is in good condition before the official start scraper conveyor operation.
2 Runtime Considerations and Requirements
Conveyor required before starting to send out a signal in advance to the staff warning, and then officially launched in case someone on the conveyor causing casualties. Work to
the attention of the valve is operating properly, pay attention to the tightness of the scraper chain is appropriate. Because the chain is too loose will cause the card
Chain, jump chain scission and chain off the road and other accidents.
Face remain flat, straight, because the face is not straight, will make two uneven tension the chain, resulting in chain wear, card chain scission and other accidents.
Meanwhile, conveyors bending length should be appropriate, not a "sharp bends." Generally curved portion is not less than eight chute; goes to grasp when
Good front and rear hydraulic jacks complement each other and avoid sharp bends. Otherwise, it is easy to cause the chute break, causing the end of chain scission or off road
accidents. Should be noted that when stopping the conveyor, the conveyor is not over. Difficulty in starting to prevent conveyors, conveyor carrying allowed to start. A
As the first boot after loading coal, the boot sequence for the first outside Houli. If the first start trough scraper conveyor, conveyor face after the start. Transport should
be the first stop in the outer (first stop after stop face conveyor trough conveyors). Parking in front of the coal on the conveyor to pull all of the net, parking
Do not built to the coal conveyor.
Blow off the coal face in running conveyors, blasting requires the entire equipment, especially piping, cables, switches and other components to protect against collapse
blasting chute. Segmented blasting should be used, to avoid overloading transport, operation difficult. During transport, a large lump or Dagan
Stone can not be put in the face conveyor. Because large rocks pass Shearer base frame, easily damaged blade, chain and gear, and even cause shearer off road accidents.
The scene will run the scraper conveyor attention problems summarized as: "flat, straight, curved, chain" before. "Flat" that is to be laid flat conveyor; "straight" face to a
straight line; "bend", bending limited, not exposing sharp bends, to show s-bend; "chain", not out of
Now loose chain phenomenon, but also not too tight.
3 runtime requirements for drivers
Drivers should be "four ground", ie ground inspection, ground repair, ground oiling, ground cleanup.
