DETAILED DESCRIPTION

[0036] The present invention is further described below with reference to the accompanying drawings and specific embodiments, but is not intended to be limiting of the present invention:

[0037] like Figure 1 and 2 As shown, the present invention provides a method for positioning a support and hanger, which is a method for positioning a support and hanger for electromechanical pipelines. Assuming that the width of the pipeline 101 is B, the distance between the two vertical poles of the support and hanger is X, and the distance between the vertical poles of the support and hanger and the pipeline 101 is Y, that is, X=B+2Y; specifically, the positioning method includes the following steps:

[0038] Step S1, such as Figure 3 , 4As shown in Figures 6 and 7, a point laser emitting device 1 and a dual-infrared line-releasing device 4 are provided, wherein the point laser emitting device 1 comprises a first scaled slide rail 11 and two point laser emitters 12 slidably arranged on the first scaled slide rail 11, a level detector 13 is arranged on the first scaled slide rail 11, a gripping handle 14 is fixedly arranged at the bottom middle part of the first scaled slide rail 11 for easy gripping, and the laser emitting direction of the point laser emitter 12 is perpendicular to the first scaled slide rail 11; the dual-infrared line-releasing device 4 comprises a second scaled slide rail 41 and two infrared levels 42 slidably arranged on the second scaled slide rail 41.

[0039] Specifically, one side of the first graduated slide rail 11 is provided with a first tightening screw 15 corresponding to the two point laser emitters 12, so that the point laser emitter 12 can be tightened by the first tightening screw 15 when needed; one side of the second graduated slide rail 41 is provided with a second tightening screw 43 corresponding to the two infrared level meters 42, so that the infrared level meters 42 can be tightened by the second tightening screw 43 when needed.

[0040] Step S2, according to the distance between the first group of support and hanger fixing points and the beams and columns in the design drawings (the first group of support and hanger fixing points are generally the hanger fixing points closer to the beams and columns), use a tape measure and a marker to mark three points at different positions on the ground or the bottom of the board, and connect the three points into a line to mark a support and hanger fixing point a in the first group of support and hanger fixing points and determine the straight line where the fixed points on the same side of the support and hanger fixing points are located.

[0041] Step S3, move the infrared level 42 on the left side of the dual infrared pay-off device 4 to the 0 scale on the leftmost side of the second scaled slide rail 41, turn on the switch 421 of the infrared level 42 on the left side, move the dual infrared pay-off device 4 (move or rotate the second scaled slide rail 41) so that the infrared light emitted by the infrared level 42 on the left side coincides with the determined straight line, tighten the second tightening screw 43 at the bottom of the infrared level 42 to fix and level the position of the infrared level 42 on the second scaled slide rail 41.

[0042] Step S4, according to the spacing X between a group of support and hanger fixing points in the design drawing, move the infrared level 42 on the right side of the dual infrared pay-off device 4 so that the spacing between the two infrared level 42 (the spacing indicated by the scale) is equal to the spacing X between a group of support and hanger fixing points, turn on the switch 421 of the infrared level 42 on the right side, and tighten the second tightening screw 43 at the bottom of the infrared level 42 on the right side to fix and level the position of the infrared level 42 on the second scaled slide rail 41.

[0043] Step S5, the operator adjusts the distance between the two laser emitters of the point laser emitting device 1 to the distance X between two fixed points of a set of support brackets and uses the first tightening screw 15 to fix the positions of the two laser emitters on the first scaled slide rail 11, turns on the two point laser emitters 12, so that the point laser emitted by one of the point laser emitters 12 coincides with the marked support bracket fixed point a, adjusts the positioning device to be horizontal and rotates for fine adjustment, so that the point lasers emitted by the two point laser emitters 12 coincide with the two infrared rays emitted by the two infrared level meters 42, and the two infrared rays emitted by the infrared level meters 42 are respectively coincident. When the point laser emitted by one of the point laser emitters 12 coincides with the marked support bracket fixed point a, the point laser emitted by the other point laser emitter 12 coincides with the other fixed point b of the two fixed points of the group of support brackets, and then the positions of the two point lasers are used as the two support bracket fixed points a and b of the first group of support bracket fixed points; since the distance between the two point lasers is the same as the distance between the two infrared rays, the two point lasers can coincide with the infrared rays on both sides only when the straight line where the two point lasers are located is perpendicular to the two infrared rays, and at this time the two overlapping points are the two fixed points a and b of the support bracket.

[0044] Step S6, taking a fixed point a in the first group of support and hanger fixing points as a reference, use a tape measure to measure one of the fixed points c of the next group of support and hanger fixing points according to the spacing between the two groups of support and hanger fixing points in the drawing, and mark it, and then use the point laser emitting device 1 to locate another fixed point d of the next group of support and hanger fixing points according to the marked fixed point c in the next group of support and hanger fixing points. Considering that the floor or ground is uneven, there is an error in measuring the fixed point on the other side with a tape measure, so the point laser emitting device 1 is used to locate another point d according to the fixed point c using the method in step S5, so as to ensure that the two groups of support and hanger fixing points are completely parallel.

[0045] In an embodiment of the present invention, Figure 2 and 5 As shown, when positioning the support bracket at the elbow of pipeline 101:

[0046] First, the ends of the two point laser emitting devices 1 are fixedly connected together end to end through a connecting piece 3 to form an extended positioning device, and the extended positioning device is provided with a first point laser emitter, a second point laser emitter, a third point laser emitter and a fourth point laser emitter in sequence from left to right, and the first point laser emitter and the second point laser emitter are located on the first point laser emitting device, and the third point laser emitter and the fourth point laser emitter are located on the second point laser emitting device.

[0047] Specifically, a square sleeve 2 is provided at the right end of the first point laser emitting device and the left end of the second point laser emitting device, and the square sleeves 2 of the two point laser emitting devices are stacked together; the connecting piece 3 is a square plug-in piece, and the square plug-in block is used to fix and connect the two square sleeves 2 stacked together.

[0048] Then, repeat the above step S6 to obtain two points e and f where the two infrared rays coincide with the elbow cross section. At this time, the center g of the elbow must be on the straight line where e and f are located.

[0049] Afterwards, the distance Z between the center of the elbow section and the closer point of the two points where the two infrared rays coincide with the elbow section is obtained by calculation; according to the curvature radius R of the elbow, the distance between points f and g can be obtained as Z=RB / 2-Y.

[0050] Then, the first point laser emitter and the second point laser emitter are moved, and the point lasers emitted by the first point laser emitter and the second point laser emitter are respectively overlapped with two points e and f where the two infrared rays overlap with the elbow cross section.

[0051] Afterwards, the third laser emitter is moved so that the distance between it and the second laser emitter is equal to the interval Z.

[0052] Finally, with the position of the third point laser emitter as the fixed point, rotate the extension positioning device (rotate one end of the first point laser emitter) in the direction of the elbow extension, and stop after the rotation angle reaches 1 / 2 of the elbow angle. At this time, the two point lasers emitted by the first point laser emitter and the second point laser emitter are a group of support bracket fixing points e and f at the pipeline elbow.
