[0038] As shown in Figure 3 , Figure 4As shown, the laser transmitter positioning assembly 4 and the laser receiver positioning assembly 6 include a connecting sleeve 43, a positioning screw 41, a connecting rod 42, a positioning plate 44, and a sliding rod 45; the laser transmitter movement assembly 5 includes a laser mounting rod 51 and a laser transmitter 52; the laser receiver movement assembly 7 includes the laser mounting rod 51 and a laser receiver 71. The positioning plate 44 is in surface contact with the flange end face, which is the surface contact positioning of the laser transmitter positioning assembly 4 and the laser receiver positioning assembly 6 with the upper flange 3 and the lower flange 1 respectively, and the sliding rod 45 is in line contact with the inner circumferential surface of the flange, which is the line contact positioning of the laser transmitter positioning assembly 4 and the laser receiver positioning assembly 6 with the upper flange 3 and the lower flange 1 respectively. The combined action of surface contact positioning and line contact positioning ensures the positioning accuracy of the measuring device.

[0039] The connecting sleeve 43 is used to connect the positioning screw 41 and the connecting rod 42, and the positioning plate 44 is fixed to one end of the sliding rod 45. The laser transmitter 52 can move along the laser mounting rod 51 to achieve accurate laser signal transmission and reception, and can perform multiple group measurements at different positions, and then perform data alignment, thereby improving the accuracy and reliability of the tower verticality measurement.

[0040] The laser mounting rod 51 provides a guide mechanism to ensure the stability and consistency of the laser transmitter 52 during movement, thereby reducing measurement errors. The laser transmitter 52 and the laser receiver 71 are respectively the core components of transmitting and receiving laser signals. Specifically, the laser transmitter 52 slides along the extension direction of the laser mounting rod 51 through a sliding structure, which can be in the form of a guide rail and a sliding block to ensure smooth and accurate movement. In addition, the laser mounting rod 51 can be slidably connected to the sliding rod 45 and move up and down along the axis of the sliding rod 45 to adapt to different height measurement requirements.

[0041] Further, the fixed connection of the connecting rod 42 with the sliding rod 45 and the connecting sleeve 43 can be achieved by welding or other mechanical fixing methods. The positioning plate 44 can adopt a fan-shaped structure to enhance its fixing effect at the end of the sliding rod 45 and the contact area of the surface contact positioning, and to enhance the positioning effect.

[0042] The connecting sleeve 43 is provided with a threaded hole, the positioning screw 41 passes through the threaded hole of the connecting sleeve 43, and the axis of the positioning screw 41 is perpendicular to the axis of the sliding rod 45 and in the same plane.

In addition, the length and diameter of the positioning screw 41 can be adjusted according to actual needs to adapt to different sizes of the sliding rod 45 and the connecting sleeve 43.

[0044] By designing the positioning plate 44 as a fan-shaped structure and fixing its small end to one end of the sliding rod 45, the problem of fixing the positioning plate 44 during the measurement of the verticality of the tower can be effectively solved. The fan-shaped structure of the positioning plate 44 can provide stable support, so that the sliding rod 45 remains stable during measurement, thereby improving the measurement accuracy.

[0045] The fan-shaped structure of the positioning plate 44 can have multiple implementation methods. For example, the positioning plate 44 can be made of metal material to ensure its strength and durability. Further, the fan-shaped structure of the positioning plate 44 can be adjusted according to specific measurement needs, such as changing the fan angle or size to adapt to different tower structures. In addition, the connection method of the sliding rod 45 and the positioning plate 44 can also be diversified, such as using threaded connection or welding, to ensure the firmness and stability of the connection. For example, the end of the sliding rod 45 is provided with a threaded hole matched with the positioning plate 44, and the positioning plate 44 can be raised and lowered along the sliding rod 45.

[0046] The laser emitter 52 slides on the laser mounting rod 51 through the sliding structure, so that the laser emitter 52 can move along the direction of the laser mounting rod 51, thereby realizing accurate measurement of the verticality of the tower. Through the design of the sliding structure, the laser emitter 52 can freely move on the laser mounting rod 51, ensuring accurate transmission and reception of the laser signal, solving the sliding problem of the laser emitter 52 in the direction of the laser mounting rod 51, and improving the accuracy and stability of the measuring device.

[0047] The sliding structure includes a guide rail and a sliding block, the guide rail is arranged on the laser mounting rod 51, and the laser emitter 52 slides along the guide rail through the sliding block.

[0048] The guide rail can be made of high-strength metal material to ensure its stability and durability in long-term use. The sliding block can be designed with a structure of ball bearings or pulleys to reduce friction and improve the smoothness and accuracy of sliding. The guide rail can be fixed on the laser mounting rod 51 by screws or welding to ensure its firmness. The sliding block can be connected with the laser emitter 52 by buckles or threads for easy installation and disassembly. The guide rail and sliding block structure are common technical means in the art and will not be described in detail.

[0049] As shown in Figure 5 , Figure 6 , the laser mounting rod 51 is slidingly connected to the sliding rod 45, and the laser mounting rod 51 can move up and down along the axis direction of the sliding rod 45. This design allows the laser mounting rod 51 to be flexibly adjusted in position on the sliding rod 45, thereby achieving accurate measurement of the perpendicularity of the tower. The sliding rod 45 is composed of an arc segment and a flat segment, and the internal shape of the laser mounting rod 51 is adapted to the arc segment and the flat segment of the sliding rod 45. The arc segment and the flat segment ensure the movement accuracy between them and limit the relative rotation of the sliding rod 45 and the laser mounting rod 51. The flat segment is provided with a positioning screw hole to fix the laser mounting rod 51. The upper end of the sliding rod 45 is a complete arc segment, which can ensure line contact positioning with the inner circumferential surface of the upper flange 3 and can realize positioning cooperation with the surface contact positioning of the positioning plate 44 to achieve more accurate positioning.
