Abstract
The invention discloses a magnetic pole center positioning process used in the process of assembling and disassembling a magnetic pole of a generator, which comprises the following steps of preparing a strip board, wherein the length of the strip board is greater than the width of 1,080mm between upper rack support arms; searching a midpoint position in the length of the strip board, arranging a positioning point at the midpoint position and hanging a weight at the positioning point by a perpendicular line; searching a support arm center position of the two upper rack support arms and horizontally erecting the strip board on which the weight is hung between the two upper rack support arms, so that the perpendicular line and the support arm center position are positioned on the same straight line, wherein the weight is positioned above a magnetic yoke and is at a distance of 4 to 5cm with the magnetic yoke; and manually turning to enable the center line of the magnetic pole, the perpendicular line and the center position of the upper rack support arms to be positioned on the same straight line. According to the invention, the problem that the center cannot be accurately aligned in the process of assembling and disassembling the magnetic pole is solved; the problem that the magnetic pole is slantingly pulled and hoisted when being lifted by an electric hoist can be avoided; times of turning can be greatly reduced; the operating time of a high pressure oil injection pump is reduced; and working efficiency is improved.
Description
Technical field
The present invention relates to the technique being applied to generator dismounting field, particularly pole center positioning process during generator magnetic pole dismounting.
Background technology
Present generator unit is when machine maintenance, pole center is determined by range estimation by service work personnel usually, easy like this pole center location of causing is inaccurate, service work personnel adjust the position of dismounting magnetic pole by artificial jiggering, or service work personnel think that dismounting magnetic pole puts in place, but in fact center also exists deviation, magnetic pole by oblique pull, easily can cause damage when lifting.
Summary of the invention
The object of the invention is to, pole center positioning process when a kind of generator magnetic pole dismounting is provided.It can avoid magnetic pole to be hung and impaired by askew skewing when dismantling, and reduces the number of times of jiggering, increases work efficiency, and reduces the labour intensity of workman.
Technical scheme of the present invention: pole center positioning process during generator magnetic pole dismounting, is characterized in that, comprise the steps:
A. prepare a strip board, the length of strip board is greater than the width 1080mm between upper bracket-arm;
B, find the midpoint of strip board length, one anchor point is set in this midpoint, mounts a weight at anchor point by vertical line;
C, find support arm center between two upper bracket-arms, the strip board level frame being mounted with weight is set between two upper bracket-arms, make vertical line and support arm center be positioned at same straight line, and weight is positioned at the top place of yoke, distance yoke is 4-5cm;
D, by artificial jiggering, the center line of magnetic pole and vertical line, upper bracket-arm is made to be centrally located at same straight line.
During aforesaid generator magnetic pole dismounting in pole center positioning process, strip board is plank, and its length is 1500-1550mm, and width is 85-95mm, and thickness is 20-30mm.
Compared with prior art, the strip board midpoint of the present invention between generator frame upper arm arranges anchor point, and at anchor point, place mounts weight by vertical line, finds pole center easily by artificial jiggering.The present invention is by above-mentioned technical scheme, magnetic pole is made to be parked in center between upper bracket-arm, solve the problem of magnetic pole center misalignment when dismounting, magnetic pole can be avoided by with occurring during electric hoist lifting askewly skewing the problem of hanging, the number of times reducing jiggering can also be greatly reduced, reduce high pressure oiling pump running time, reduce personnel labor intensity, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Being labeled as in accompanying drawing: 1-upper bracket-arm, 2-magnetic pole, 3-strip board, 4-vertical line, 5-weight, 6-yoke, 7-support arm center.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
Embodiment.Pole center positioning process during generator magnetic pole dismounting, comprises the steps: that A. prepares a strip board 3, and the length of strip board 3 is greater than the width 1080mm between upper bracket-arm 1;
B, find the midpoint of strip board 3 length, one anchor point is set in this midpoint, mounts a weight 5 at anchor point by vertical line 4;
C, find support arm center 7 between two upper bracket-arms 1, strip board 3 level frame being mounted with weight is set between two upper bracket-arms 1, make vertical line 4 and support arm center 7 be positioned at same straight line, and weight is positioned at the top place of yoke 6, distance yoke is 4-5cm;
D, by artificial jiggering, the center line of magnetic pole 2 and vertical line, upper bracket-arm is made to be centrally located at same straight line.
Strip board 3 can be plank, and its length is 1500-1550mm, and width is 85-95mm, and thickness is 20-30mm.Preferred size is length is 1520mm, and width is 90mm, and thickness is 25mm.Such size is more moderate, can stably be erected between upper bracket-arm, not waste material.
The dismounting process of generator magnetic pole: prepare a strip board 3, the length of strip board 3 is greater than the width 1080mm between upper bracket-arm 1; Find the midpoint of strip board 3 length, one anchor point is set in this midpoint, mount a weight 5 at anchor point by vertical line 4; Find the support arm center 7 between two upper bracket-arms 1, strip board 3 level frame being mounted with weight is set between two upper bracket-arms 1, make vertical line 4 and support arm center be positioned at same straight line, and weight is positioned at the top place of yoke 6, distance yoke is 4-5cm; By artificial jiggering, the center line of magnetic pole 2 and vertical line, upper bracket-arm is made to be centrally located at same straight line, now the center of magnetic pole between upper bracket-arm, namely between middle two screw rods of magnetic-pole connection wire pressing plate.Mark is carried out in the position of then placing strip board 3 on upper bracket-arm, when other magnetic poles of dismounting, strip board 3 is placed on same position, very simple and efficient.
After the center of magnetic pole is found accurately, with electric hoist or other boom hoistings by magnetic pole lifting dismounting, can avoid occurring because askew skewing is hung and situation about being damaged.
