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 be applied to the technology in generator dismounting field, particularly pole center positioning process during the generator magnetic pole dismounting.
Background technology
The generator unit is when machine maintenance now, pole center is definite by estimating by the service work personnel usually, the easy like this pole center location of causing is inaccurate, the service work personnel adjust the position of dismounting magnetic pole by artificial jiggering, perhaps the service work personnel think that the dismounting magnetic pole puts in place, but in fact the center exists deviation, and magnetic pole can tiltedly be drawn when lifting, causes damage easily.
Summary of the invention
The objective 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 dismounting, and the number of times of minimizing jiggering is increased work efficiency, and reduces working strength of workers.
Technical scheme of the present invention: pole center positioning process during the generator magnetic pole dismounting, it is characterized in that, comprise the steps:
A. prepare a strip plate, the length of strip plate is greater than the width 1080mm between upper bracket-arm;
B, find the midpoint of strip plate length, in this midpoint one anchor point is set, articulate a weight at anchor point by vertical line;
C, find the support arm center between two upper bracket-arms, the strip plate level that is mounted with weight is set up between two upper bracket-arms, make vertical line and support arm center be positioned at same straight line, and weight being positioned at the top place of yoke, is 4-5cm apart from yoke;
D, by artificial jiggering, make the center line of magnetic pole and vertical line, upper bracket-arm be centered close to same straight line.
In the pole center positioning process, the strip plate is plank during aforesaid generator magnetic pole dismounting, and its length is 1500-1550mm, and width is 85-95mm, and thickness is 20-30mm.
Compared with prior art, the strip plate midpoint of the present invention between generator frame upper arm arranges anchor point, and the place articulates weight by vertical line at anchor point, finds pole center easily by artificial jiggering.The present invention is by above-mentioned technical scheme, make magnetic pole be parked in center between the upper bracket-arm, solved magnetic pole center problems of missing aim when dismounting, can avoid magnetic pole by the askew problem of hanging that skews of time appearance with the electric hoist lifting, can also significantly reduce the number of times that reduces jiggering, reduce high pressure oiling pump running time, reduce personnel labor intensity, increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
Being labeled as in the accompanying drawing: 1-upper bracket-arm, 2-magnetic pole, 3-strip plate, 4-vertical line, 5-weight, 6-yoke, 7-support arm center.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples, but not as the foundation to the present invention's restriction.
Embodiment.Pole center positioning process during the generator magnetic pole dismounting comprises the steps: that A. prepares a strip plate 3, and the length of strip plate 3 is greater than the width 1080mm of 1 of upper bracket-arm;
B, find the midpoint of strip plate 3 length, in this midpoint one anchor point is set, articulate a weight 5 at anchor point by vertical line 4;
C, find the support arm center 7 between two upper bracket-arms 1, strip plate 3 level frames that are mounted with weight are set between two upper bracket-arms 1, make vertical line 4 and support arm center 7 be positioned at same straight line, and weight being positioned at the place, top of yoke 6, is 4-5cm apart from yoke;
D, by artificial jiggering, make the center line of magnetic pole 2 and vertical line, upper bracket-arm be centered close to same straight line.
Strip plate 3 can be plank, and its length is 1500-1550mm, and width is 85-95mm, and thickness is 20-30mm.Preferred sizes is that length is 1520mm, and width is 90mm, and thickness is 25mm.Size is more moderate like this, can stably be erected between the upper bracket-arm, not waste material.
The dismounting process of generator magnetic pole: prepare a strip plate 3, the length of strip plate 3 is greater than the width 1080mm of 1 of upper bracket-arm; Find the midpoint of strip plate 3 length, in this midpoint one anchor point is set, articulate a weight 5 at anchor point by vertical line 4; Find the support arm center 7 between two upper bracket-arms 1, strip plate 3 level frames that are mounted with weight are set between two upper bracket-arms 1, make vertical line 4 and support arm center be positioned at same straight line, and weight being positioned at the place, top of yoke 6, is 4-5cm apart from yoke; By artificial jiggering, make the center line of magnetic pole 2 and vertical line, upper bracket-arm be centered close to same straight line, the center of magnetic pole this moment between upper bracket-arm is namely between middle two screw rods of magnetic pole connecting line pressing plate.Carry out mark in the position of upper bracket-arm placement strip plate 3 then, when other magnetic poles of dismounting, strip plate 3 is placed on same position, very simple and efficient.
After the center of magnetic pole found accurately,, can avoid occurring because of the askew situation about being damaged of hanging that skews with magnetic pole lifting dismounting with electric hoist or other boom hoistings.
