Preparation before installation: Measure the spacing of embedded bolts before installation, measure the elevation of each installation foundation with a level, and mark the centerline of the headstock and tailstock, and then use theodolite to find the belt installation baseline.
Installation process: basic acceptance-belt conveyor leg and middle frame installation-counterweight device installation-head frame, tail frame and drive device frame installation-drum and roller installation-unit installation-belt pulling- -Refueling and debugging.
Installation process:
1. Belt conveyor legs and intermediate frame: Use theodolite to find the center line before installation, and then draw the position of each leg's pile point according to the center line position. If there is embedded iron, make appropriate adjustments according to the position of the embedded iron. Adjust to facilitate the installation company, and each support leg should be welded firmly with the embedded part.
2. Counterweight device: When installing the counterweight device, the parallelism between the two force columns should be ensured, and at the same time the verticality should be ensured. After the counterweight device is installed, the protective railing should be installed immediately in consideration of safety.
3. Headstock, tailstock and driving device frame: first check the elevation of the installation foundation, find the center line, and pay attention to the axis deviation of the head and tailstock not greater than ±1.5. Pay attention to the setting of the shim during installation. The shim should be set in the main load-bearing position according to the requirements of the specification. A pair of shim should be placed on both sides of each connecting bolt. The inclined shim should be set in pairs, and the number of shim should not exceed 5 pieces. When placing the shim, put the thinner shim in the middle of the thicker one. After the adjustment, the shim should be welded firmly and the bolts should be tightened.
4. Roller and idler: When installing the drum and idler, check the rotation of the bearing part. If the rotation is not flexible, it should be repaired or replaced in time. The position of the drive roller and the reversing roller needs to be adjusted during debugging, and the tightening torque of the bolts is 75-80% of the final tightening torque.
5. Unit installation: Unit installation should meet the requirements of "General Specification for Construction and Acceptance of Mechanical Equipment Installation Engineering" (GB50231-98) and relevant national codes. The deviation of the unit center line is 0.02mm, the radial error of the coupling is 0.05mm, the end face runout value is 0.02mm, and the gap between the half couplings is 3~5mm. It should also be ensured that the levelness of the unit and the use of the shim meet the requirements of the specification.
6. Pull the belt: the manufacturer or professional is responsible.
7. Refueling and debugging: make a refueling record when refueling, add appropriate mechanical oil or gear oil according to the reducer model, and the amount of refueling is to the indicated position; add butter (lithium-based grease) to each bearing seat position of the belt conveyor. Personnel should be set up at the head, tail and middle position of the belt conveyor during debugging. The staff should pay attention to whether the belt conveyor is running normally. If there is a fault or serious deviation, the operation should be stopped immediately; the inching operation should be taken first during the trial operation, when the electric is normal Debugging will be carried out at the same time. After the belt conveyor runs off the track, the staff should adjust the relevant parts based on experience, and ensure the normal operation of the belt conveyor after multiple adjustments. The staff should also use the walkie-talkie or blow the whistle to keep in touch, and always pay attention to the safety of the machine and personnel (self and others), and illegal operations are strictly prohibited. During commissioning, check the temperature of the motor, reducer and each bearing position, use a stethoscope to check the noise of the reducer and make a record of the commissioning.
