[0003] When installing pipeline supports and hangers, usually multiple columns are first installed on the ceiling, and then two pipeline supports and hangers are installed between each corresponding pair of columns, and the pipeline is placed after installation. However, before installing the columns, the installation positions of the columns need to be located. Traditional positioning methods mainly use basic tools such as spirit levels, tape measures, and plumb lines to draw grid lines on the ceiling to help determine the positions of the columns. However, this positioning method takes a long time. In large-scale engineering projects, it will significantly affect the progress of the entire project. In addition, the accuracy of positioning depends to a large extent on the experience and technical level of the operators. Operations by different personnel may result in positioning errors.

[0023] Refer to Figures 1-5 As shown, the positioning mechanism further includes a first threaded block 7, a second screw 13 and a second threaded block 18. The first threaded block 7 is threadedly connected to the rear end of the first sliding rod 8. The front side of the first threaded block 7 closely adheres to the rear side of the sliding frame 1, so that the first sliding rod 8 is fixed inside the sliding frame 1. And a rubber pad is provided on the contact surface between the first threaded block 7 and the sliding frame 1, which can increase the friction between the first threaded block 7 and the sliding frame 1 and prevent the first threaded block 7 from loosening. The second threaded block 18 is threadedly connected to the lower end of the second sliding rod 17. The top surface of the second threaded block 18 closely adheres to the lower side of the slide rail 9, so that the second sliding rod 17 is fixed to the lower part of the slide rail 9. And a rubber pad is provided on the contact surface between the second threaded block 18 and the slide rail 9, which can increase the friction between the second threaded block 18 and the slide rail 9 and prevent the second threaded block 18 from loosening. The second screw 13 is threadedly connected to the upper end of the second sliding rod 17, and the front end of the second screw 13 abuts against the outside of the sphere 14, so that the sphere 14 is fixed to the upper end of the second sliding rod 17.

[0024] Refer to Figures 4-5 As shown, it also includes a motor 15, a belt 16, a clamping block 19 and a clamping groove 20. The middle part of the second sliding rod 17 is fixedly connected with the motor 15 inside. The output shaft of the motor 15 is wound with the belt 16, and the belt 16 is a non-elastic belt, such as a nylon belt or a polyester belt, which is suitable for occasions where precise alignment is required. One end of the belt 16 is fixedly connected to the outside of the output shaft of the motor 15, and the other end passes out of the outside of the second sliding rod 17 and is fixedly connected with the clamping block 19. The outside of the second sliding rod 17 is connected with the clamping groove 20 by means of a bolt connection, and the clamping block 19 can be clamped with the clamping groove 20.

[0025] When the device needs to be used, first, the operator uses the nut 104 to fix the angle iron 101 between the two columns 105. Then, pinch the knob 5 with hand and rotate the first screw rod 3 upward to the limit position. Place the mounting bracket 2 on the right front side of the angle iron 101. The bottom surface of the limit block 6 contacts the top surface of the angle iron 101 to quickly determine the position of the mounting bracket 2. Then, rotate the first screw rod 3 downward to drive the pressing block 4 to move downward and press on the angle iron 101 to achieve the quick fixation of the mounting bracket 2. Next, directly install the two columns 105 at the appropriate positions on the ceiling 106. Then, check the spirit level 11 to ensure that the double-line laser emitter 10 is in a horizontal state. Rotate the second threaded block 18 downward to release the fixation of the second sliding rod 17. Then, start the motor 15. The motor 15 rotates forward to loosen the belt 16. Then, pinch the clamping block 19 with hand and pull the belt 16 out from the output shaft of the motor 15 and wind it around the lower end of the left front column 105. Then, engage the clamping block 19 with the card slot 20. And after the clamping block 19 is engaged with the card slot 20, the motor 15 can be started to rotate in reverse. The output shaft of the motor 15 rotates in reverse to tighten the belt 16. During the tightening process, if there is friction between the belt 16 and the column 105, the belt 16 can still be completely straightened and tightened under the continuous tightening force of the motor 15. Thus, as the pulling force increases, the belt 16 will pull the second sliding rod 17 to slide in the slide rail 9 and align with the left front column 105 to adjust the horizontal position of the double-line laser emitter 10 to ensure that the lower laser line emitted subsequently is horizontally aligned with the center point of the left front column 105. Then, rotate the second threaded block 18 upward to fix the second sliding rod 17. Next, press the switch 12 to turn on the double-line laser emitter 10 to make the double-line laser emitter 10 emit two laser lines. One of the upper laser lines irradiates on the ceiling 106, forming a straight laser line on the ceiling 106. The other lower laser line shoots straight to the right. Then, align the new column 105 with the laser line on the ceiling 106 and set the distance between the new column 105 and the original column 105 according to the actual requirements on site. In this way, the new column 105 can be quickly installed. Similarly, the new column 105 can be quickly installed on the other side. After both new columns 105 are installed, put the new angle iron 101 on the two new columns 105. The height of the new angle iron 101 can be quickly positioned according to the laser line emitted from the lower side of the double-line laser emitter 10 to ensure that the height of the new angle iron 101 is the same as that of the original angle iron 101. After the height of the new angle iron 101 is positioned, the new angle iron 101 can be fixed on the new column 105 through the nut 104. In this way, under the action of the double-line laser emitter 10, the positions of the column 105 and the angle iron 101 can be quickly positioned, improving the installation efficiency.

[0026] After the installation of the column 105 and the angle iron 101 is completed, the motor 15 is started to rotate forward so that the output shaft of the motor 15 releases the belt 16, and then the clamping block 19 is disengaged from the clamping slot 20. Thereafter, the motor 15 is started to rotate reversely so that the output shaft of the motor 15 reverses and rewinds the belt 16, so that the belt 16 is rewound on the output shaft of the motor 15, and the mounting frame 2 is removed from the left angle iron 101. Finally, the switch 12 is pressed again to turn off the dual-line laser transmitter 10, and the pipeline is placed between every two horizontally aligned limit rings 102 to fix it.

[0027] It is worth noting that, due to space limitations or in order to meet specific engineering requirements, when it is necessary to install the two right columns 105 at an angle, the second screw 13 is rotated backward to disengage the sphere 14, and then the sphere 14 is rotated to adjust the dual-line laser emitter 10 to a suitable angle, and the second screw 13 is rotated forward to press against the sphere 14 to fix the dual-line laser emitter 10.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
