Technical solution of the present invention is as follows:

Bulk goods wheel anchor lip is at the preassemble method in segmentation stage, and its feature is, the method comprises the steps:

1. take deck as basal plane on horizontal moulding bed to bulk goods wheel anchor lip segmentation carry out anti-state placement, find out any two points P1 and P2 on the line of centers of moulding bed ground, utilize total station survey P1,2 definite straight line L1 of P2, at the vertical plane of straight line L1, determine 1 P3, make the vertical projection point of a P3 fall straight line L1 above, by a P1, some P2, some P3, make the vertical plane S1 parallel with hull center buttock;

2. utilize total powerstation with hull horizontal surface parallel direction on determine arbitrarily 1 P4, take a P4 as benchmark, find the some P5 and some P6 identical apart from the height of hull horizontal surface with some P4 apart from the height of hull horizontal surface, and some P4, some P5 and some P6, not on same straight line, make the horizontal surface S2 parallel with hull horizontal surface by a P4, some P5, some P6;

3. find out on anchor lip end face three not the at a point P7 on same straight line, some P8 and some P9, by a P7, some P8 and some P9, make anchor lip end face S3;

4. according to anchor lip installation drawing, require to find out theoretical included angle A 1 angle of anchor lip end face and center buttock, theoretical included angle A 2 angles of anchor lip end face and horizontal surface, and record;

5. utilize total powerstation to calculate actual included angle A 3 angles between vertical plane S1 and anchor lip end face S3, actual included angle A 4 angles between horizontal surface S2 and anchor lip end S3;

6. actual included angle A 3 and A4 are compared with corresponding theoretical included angle A 1 and A2 respectively, according to difference to anchor lip carry out up and down, the adjustment of position, left and right, actual included angle A 3 is equated with theoretical included angle A 1 with 3, actual included angle A 4 equates with theoretical included angle A 2.

Compared with prior art, the invention has the beneficial effects as follows, by face face angle, carry out accurate positioning anchor lip, avoided setting accuracy deviation and the subsequent modification under orthodox method, thereby actv. is saved cost of installation.
