Use of belt conveyor
Before starting up, check the motor, reducer, bottom, surface roller, adhesive tape, joint, reduction gearbox oil level and tensionDevice, backstop device, coal baffle, sweeper, various protections (smoke, deviation, coal level, temperature, speeddegree), fire fighting equipment, signal devices, operation buttons, etc.
(1) After receiving the start-up signal (the signal is specified as one stop, two open and three inching), inching firstSecond, then start normally, open the spray device to spray dust.
(2) Whether the motor, reducer, bearings and rotating parts have abnormal noise or vibration, and whether the temperature exceedsThe specified value (motor temperature should not exceed 80 ℃, bearing temperature should not exceed 70 ℃).
(3) Whether the adhesive tape is deviated, slipped or torn, and whether the joint is complete.
(4) If any abnormal phenomenon is found during operation, stop immediately, and turn the handle of the control switch to the power-off position lockOK, then hang up the blackout sign and continue driving after handling it.
(5) Before stopping operation, the coal (gangue) on the belt conveyor should be pulled clean; before and after the driver leaves the driving deviceWhen it is beyond 15m, turn the switch handle to zero position and lock it.
(6) After the work is finished, stop the machine after all the coal and gangue in the belt conveyor are transported out, and then close the spray.Valve, and the next belt conveyor to send a stop signal, the control switch hand plate to the power-off position,Tighten the locking bolts.
Daily maintenance of 3. belt conveyor
1. Daily maintenance of sweeper
The sweeper or sweeping scraper shall not press the surface of the tape or roller too tightly or the clearance is too large;The main point of the inspection is to check the contact condition and the integrity of the parts, and the damaged parts should be replaced in time;The coal dust on the sweeper shall be removed in time when the vehicle is stopped.
2. Inspection and maintenance of tensioning force
Roller slippage is usually a manifestation of insufficient tape tension, which can be eliminated by adjusting the tensionPhenomenon; Excessive tension will cause vibration of the tape below; the adjustment of tension is based on the load cell pressureForce meter numerical control or conveyor belt on the sensing drum does not produce slip shall prevail.
3. Inspection and maintenance of temperature of reducer, motor and all roller bearings
For equipment with oil leakage in the reducer and hydraulic coupling, the oil filling amount should be checked regularly and timely.To supplement; for serious oil leakage, should be timely replacement or repair seals.
4. Inspection and maintenance of belt deviation and jammed
Long-term deviation is the main cause of tape edge napping, cracking and even longitudinal tearing.The deviation should be adjusted in time.
5. Inspection and maintenance of tape joints and wear
Breaking usually occurs at joints or severely worn areas, and in order to avoid breaking the belt during full load operation, damage toSerious adhesive tape, especially the joint, must be cut off and redone in time. During redoing, ensure that the cut and the center of the adhesive tape are guaranteed.The line is vertical.
6. Weekly inspection
Inspection of electrical control and safety devices, the operation of all control devices must be checked at least once a week.
Treatment of Common Faults of 4. Belt Conveyor
1. Prevention of tape slippage
(1) Strengthen the operation and management of the belt conveyor, enhance the driver's sense of responsibility, and deal with the slippage in time.
(2) It is strictly forbidden for water, coal slime, coal dust or lubricating oil to enter between the drum and the lower tape, causing friction system.The number decreases.
(3) Eliminate heavy load shutdown and load start.
2. Deviation treatment method during conveyor belt operation
(1) Check the non-coincidence between the transverse center line of the idler and the longitudinal center line of the belt conveyor. If notIf the coincidence value exceeds 3mm, the idler group shall be adjusted. The specific method is to which side the conveyor belt is biased, and the idler group shall be adjusted.Which side of the roller group moves forward in the direction of the conveyor belt, or the other side moves backward.
(2) Check the deviation of the two planes of the head and tail frame mounting bearing seat. If the deviation of two planesMore than lmm, two planes should be adjusted in the same plane. The adjustment method of the head roller is: if the conveyor beltIf the roller deviates to the right side, the bearing seat on the right side of the roller shall move forward or the bearing seat on the left side shall move backward;If the belt deviates to the left of the drum, the bearing seat on the left side of the drum shall move forward or the bearing seat on the right side shall move backward. TailThe adjustment method of the roller is opposite to that of the head roller.
(3) Check the position of the material on the conveyor belt. The material is not centered on the cross section of the conveyor belt and will be guided.The conveyor belt is off-track. In use, the material should be centered as much as possible, and the baffle plate can be added to change the square of the material.direction and position.
