maintance for the concrete pole moulds

1 Operation Manual For Maintenance Man

1.1 The deformation of concrete spun pole moulds should be examined first (by the method of staying wire). If one or two sections of moulds is found deformation, open the deformed one.

1.2 The worn running wheel of concrete electric pole moulds should be processed with surfacing, polishing. If welding is released, it should be weld before the cleaning of the wheel.

1.3 Every lifting lug should be examined and replaced timely if found defective; the lifting hole should be enlarged if the hole is too small; the lifting rings of the upper mould and below should be aligned.

1.4 If the circular bar plate and longitudinal bar plate deform, they should be corrected and fully welded.

1.5 The connection flange should be examined to see if deformed or welding-released. The badly damaged must be replaced.

1.6 The damaged and missing links, bolts, heal blocks, cotter pins and locating pins should be repaired and replaced.

2 Operation Manual For Opening Mould, Straightening Man

2.1 The internal and external seam should be aligned along the cutting of the mould.

2.2 The seriously deformed flange should be corrected.

2.3 Make up the damaged or missing bolts, spacer, cotter pin and locating pins.

2.4 The cracked internal wall of mould or edge must be broke and welded, the surface should be finished finally.

2.5 The concrete pole moulds should be straightened with press machine.

3 Operation Manual For Mould Joining Man

3.1 The joint of the moulds should be polished with groove and smoothed so that the mould will keep straight and smooth.

3.2 The welding will not be done until the supporting plate is installed rightly. Weld and polish the worn inner hole of bearing plate.

3.3 Make up the longitudinal and horizontal plate, reinforced bars and straighten and weld the crooked.

3.4 The released weld of running wheel must be cleaned in the seam and not weld until the electric current is adjusted.

3.5 The cracked lifting rings should be placed where it is placed. The misplaced should be cut out and reinstalled. The smaller ring should be dealt with.

3.6 Cut out and change the damaged screw ear and make up the screws, spacer, cotter spins and locating spins. The drainage hole should be examined and dredged.

3.7 Examine, supplement and dredge the drain hole of the lower mould of bearing plate.

4 Operation Manual For Mould Cavity Repairing Man

4.1 The joint should be flat and straight and strongly welded. Weld the damage by hit, strain and valley by the mould edge again.

4.2 Supplement the missing screw, cotter spins, locating pins; examine the weld releasing of everywhere of the mould and the misplace of the flange of fixed part and repair them.

4.3 Examine the width of the seam of mould closing after the mould is closed and process it accordingly and weld the worn screw–socket.

5 Operation Manual For Running Wheel Changing Man

5.1 The height of replaced running wheel should be same and the joint seam of moulds should be less than 5mm.

5.2 The joint and flange in the fixing end should be examined to confirm the change.

6 Operation Manual For Lathe Worker

6.1 The dimensions of running wheel of whole mould should be totally same and the fixing ends and joint flange must be processed if found uneven and displaced.

7 Quality Track

7.1 The repair of the mould should be recorded according to the requirements of maintenance of mould and record card. The repairing parts and list of repair worker should be noted after the repair.

7.2 The whole mould should be examined by the repair group after the repair. If the self-repair passed, the quality inspector should be informed timely to recheck. The concrete electric pole steel moulds are not available unless pass the examination.
