As shown in the figure, the laser emitter 1 is provided with a mounting seat 4, the laser emitter is located at the top of the mounting seat, and the mounting seat is arranged at the top of a small platform on one side; The laser receiver B3 is provided with a mounting rod 6, and the laser receiver B3 is located at the top of the mounting rod. The mounting rod 6 is arranged at the top of a small platform on the other side; the small platform is a vertical pole.
[0019] The laser receiver A2 is provided with a connecting rod 7, the laser receiver A2 is located at the top of the connecting rod, the connecting rod is a vertical rod, and the connecting rod is arranged next to the laser receiver B3; the laser receiver A2 is also provided with a movable connecting rod 5, the laser receiver A2 is arranged at the top of the movable connecting rod, and the bottom end of the movable connecting rod is an arc-shaped bottom end, so that it can be placed on the arc-shaped top surface of the roller to be measured when in use; the laser transmitter (1) itself has a leveling function. The bottom end of the movable connecting rod is an arc-shaped bottom end matched by two bent rods.
[0020] The computer is a tablet computer, which receives data sent by the laser receiver A2 and the laser receiver B3 via Bluetooth, and performs calculations in combination with pre-stored data. The tablet computer 8 makes a judgment on the received data, issues an alarm in time, and terminates the measurement process to avoid invalid measurements. The tablet computer (8) gives special prompts by displaying different colors for measurement points that exceed the allowable error range.
[0021] Example 2 The method for using the laser arc alignment instrument for fan-shaped segments of the present invention: 1. Small platforms are set on both sides of the fan-shaped segment centering platform for placing the mounting seat 4 and the monitoring position mounting rod 6.
[0022] 2. The laser transmitter 1 is fixed on the fan-shaped segment centering platform through the mounting base 4, and the laser transmitter 1 itself has a leveling function.
[0023] 3. The laser receiver B3 is installed on the fan-shaped segment centering platform through the monitoring position mounting rod 6 to monitor the working status of the laser transmitter 1 at any time during the measurement process. In the case that the laser transmitter 1 is accidentally touched, the vibration exceeds the standard, or the operation is abnormal, the tablet computer 8 will judge the received data, and will promptly alarm and terminate the measurement process to avoid invalid measurement.
[0024] 4. The laser receiver A2 is first connected to the connecting rod 7 to measure the height of the four mounting surfaces. The connecting rod 7 is a modular type and can be applied to different types of sectors.
