Illustratively, step 102 includes the following steps.
The method comprises the following steps of firstly, starting a laser transmitter, and recording the positions of at least three light spots on the bilge by adjusting the position of a mounting seat on a mounting table.
The mounting base can be slightly rotated manually, namely the position of the mounting base on the mounting table can be adjusted.
And secondly, determining whether the area of a circular area where at least three light spots are located at the bilge is smaller than a set area.
When the area of the circular area of the at least three light spots at the position of the bilge is smaller than the set area, determining that the laser emitted by the laser orienting device is superposed with the axis of the pipeline mounting hole. And when the area of the circular area of the at least three light spots at the position of the bilge is larger than the set area, determining that the laser emitted by the laser orienting device is not superposed with the axis of the pipeline mounting hole, and executing a third step. When the area of a circular area where at least three light spots are located at the bilge is equal to a set area, determining whether the laser emitted by the laser orienting device coincides with the axis of the pipeline installation hole or not.
And thirdly, determining the central positions of the at least three light spots at the bilge.

And fourthly, replacing the screw mounting holes of at least one adjusting screw on the corresponding angle and adjusting the position of the top plate template on the supporting seat so as to enable the position of the light spot on the bilge to be close to the central position.
For example, the adjusting screws can be taken out of the current screw mounting holes and then mounted to the screw mounting holes near the current screw mounting holes, so that the space between the adjusting screws changes, the top plate template is moved to move on the supporting seat, and the position of the top plate template on the supporting seat is adjusted to enable the position of the light spot on the cabin bottom to be close to the central position.
And step 102 is executed again after the fourth step, namely the relative position relationship between the laser orientation device and the supporting seat is readjusted, so that the laser emitted by the laser orientation device is superposed with the axis of the pipeline mounting hole.
Illustratively, when the area of the circular area where the at least three light spots are located at the bilge is smaller than the set area, it may be further determined whether the laser emitted by the laser directing device coincides with the axis of the pipeline installation hole based on the distance, and based on this, step 102 further includes a fifth step to a seventh step.
And fifthly, when the areas of the circular areas of the positions of the at least three light spots at the bilge are smaller than the set area, selecting at least three position points from the top plate template.
And sixthly, measuring the distances between the at least three position points and the bilge.

And executing a third step when the deviation between the distances between the at least three position points and the bilge is larger than a set value.
For example, when the deviation between the distances between the at least three position points and the bilge is smaller than a set value, it may be further verified whether the laser emitted from the laser directing device coincides with the axis of the pipeline installation hole, based on which step 102 further includes an eighth step to a ninth step:

And step nine, detecting whether the generated light spots are positioned in a circular area where the positions of at least three light spots on the bilge are positioned.
And when the generated light spots are positioned in the circular area where the positions of the at least three light spots on the bilge are positioned, determining that the laser emitted by the laser orientation device is superposed with the axis of the pipeline mounting hole. When the generated light spots are not located in the circular area where the at least three light spots are located at the bilge, the third step is performed.
It should be noted that the laser orientation device is suitable for installation of a deep-well pump, and is only a special example provided by the embodiment of the invention, and the laser orientation device can be applied to all similar projects needing to correct the cylindrical surface coaxial line. Based on the foregoing, an exemplary deep-well pump installation positioning scenario is briefly described below.
Firstly, a laser orientation device is installed on a supporting seat of a deep well pump, the change of light spots of laser beams on the bilge is observed through rotating an installation seat, and the light spots are recorded through rotating different positions. Spot positions in four directions can be recorded.
Secondly, connecting the recorded four light spots of the bilge and searching the center positions of four points as far as possible.
And thirdly, adjusting the position of the top plate template relative to the supporting seat to enable the light spots to move to the center positions of the four points, rotating the laser again, detecting the new positions of the four light spots, and marking.
Fourthly, the first and the second are repeated, so that the four light spots are as much as possible in the same circle, and the smaller the radius of the circle, the better.
Fifthly, according to the installation precision of the deep-well pump, the requirement of the light spot forming circular area is determined, and the top plate template is adjusted until the light spot meets the requirement. When the light spot meets the requirement, the top plate template is parallel to the bilge or forms a plane angle.
Whether the top plate template is parallel to the bilge or not can be adjusted in parallel in two ways. In the first mode, distance measurements can be made at four different locations using a distance measuring device, such as a tape measure, and when the measurements are equal, the ceiling template is parallel to the bilge, and the laser beam is the vertical centerline of the deep well pump installation. In the second mode, a plurality of laser range finders installed on the laser orientation device are used for measuring the distances of a plurality of different positions to complete parallel adjustment. The laser range finder can automatically read results, and the efficiency is faster than that of a tape measure.
And sixthly, rotating the laser again, and if the light spot is far away from the minimum circular area, repeating the steps from the first step to the sixth step until the circular area requirement is met. When it is necessary to say, the newly determined circular domain is not required to be a concentric circular domain with the previously determined circular domain.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
