Routine Maintenance And Repair Of Elevator
discover and eliminate potential causes of accidents are eccential
. Main hoist operator in equipment daily maintenance and maintenance outside, still should participate in mine lifting machine maintenance and repair work.
One, hoist equipment routine maintenance
Daily maintenance work, refers to a plan to do a good job in equipment lubrication, daily inspection and cleaning. Do the day-to-day maintenance of equipment, timely inspection and plan repair work, is to reduce the mechanical parts wear, prolong the service life of the hoisting machine is very effective method, but also for the elevator repair and lay a good foundation, greatly reducing the number of repair.
Two, hoist equipment regular check
Elevator inspection is divided into daily inspection, weekly inspection and monthly inspection, should be directed to the hoist performance, structural characteristics, working conditions and repair maintenance experience to develop the specific content. Results of examination and repair content shall be entered in the maintenance records, maintenance and by the signature of the person in charge.
The basic content of1.
(1) inspection hammer check portions connecting parts ( such as bolts, rivets, pin ) is loose, the inspection hole was observed for speed reducer of gear meshing.
(2) check the lubrication system oil supply situation and the braking system working status.
(3) check the depth indicator of screw nut shaking, and protective devices and instruments such as the normal movements.
(4) to check the stability of rotating part, such as bearing vibration, the base and foundation bolts ( screws ) is loose.
(5) test over-rolling protection device.
(6) the hand to try a slack rope signal device, test signals ( including full storehouse, starting, stopping, emergency signal etc. ).
(7) check the contactor ( signal panel, control panel, rotor phase changer etc) contact wear, for burning to repair ( with emery cloth and small file ) or replaced, in order to maintain its good contact.
(8) check the adjusting rope and sheave rotation, such as gaskets, bearings.
(9) examination of hoisting container and its affiliated institutions ( such as car arrester, connecting device, pot ears ) structure is a normal situation.
(10) examined the anti-falling device system for spring, catcher, a linkage rod, connection and lubrication condition.
(11) check wellhead loading device (such as a pusher, climb car engine, dumper, car arrester, shake or the pot base, security door ) work.
(12) in accordance with the" coal mine safety regulations" provisions, check the elevator wire rope working condition and the wire rope on the drum arrangement.
2 week check of basic content
Weekly inspection content including daily inspection of the content, but also for the following tasks:
Check the brake system (1) ( disc brake and brake ), especially the hydraulic station and the brake action, adjust the clearance of brake shoe, fastening connection mechanism.
(2) examined a variety of security ( such as volume, speed, speed etc.) device action; check cylinder rivet is loose, the weld is cracking; examination of steel wire rope on the drum arrangement, as well as the rope head fixing is reliable.
(3) friction hoisting machine check leading wheel pressing block solid and guide wheel bolts and gasket etc..
(4) check and clean the anti-dropping device protector, when necessary to adjust and oiling; check the brake steel wire rope and its buffer device connection.
(5) to repair and adjust the wellhead loading equipment spare parts, if necessary, replacement.
(6) according to the" coal mine safety regulations" of 404th,410, check the balance rope working condition.
3 month basic content.
Monthly inspection of basic content including weekly inspection content, still need to undertake the following tasks:
(1) open the reducer observation hole cover and check the door, detailed examination of the mesh of the gears, two gear inspection hammer check the bolts of counterparts, also should check whether the occurrence of cracks and spokes.
(2) a detailed inspection and adjustment of braking system and safety protection device, when necessary to clean the hydraulic parts and pipeline.
(3) open the coupling, check its working condition, such as the gap, end tilt, radial displacement, connecting bolt, spring and the inner and outer teeth and whether the fracture, loosening and wear.
(4) check section bearing clearance.
(5) inspection and replacement of parts of the lubricating oil, cleaning parts lubrication system components ( such as the oil pump, the oil filter and pipeline etc. ).
(6) cleaning and oiling anti-dropping device system, to adjust the clearance.
(7) check the shaft equipment, such as a tank, bunton and anti-falling device for brake steel wire rope, wire rope and other buffer.
(8) test safety protection device and the braking system of the action.
