Description

Technical Field

[0001] The present invention relates to the field of industrial measurement technology, and in particular to a guide rail angle measuring device and a guide rail angle measuring method. Background Art

[0002] In fields such as machinery manufacturing and power equipment installation, it's common to measure the bend or twist angle of guide rails to ensure assembly accuracy. Traditionally, this method uses a metal protractor or level. The protractor's arms are placed on either side of the guide rail's bend (or twist section), and the scale is adjusted to ensure a perfect fit. The angle reading is then read. This method is inefficient and requires manual alignment of the rail's ends, repeated adjustments, and manual readings, which is time-consuming.

[0003] Place the level on the horizontal reference section of the guide rail and adjust the bubble to the center (zero). Move the level to the bend section and observe the bubble offset distance. Calculate the angle based on the level length (L) and the bubble offset height (h) using the formula θ = arctan(h / L). This method has limited accuracy and relies on operator experience. It is prone to errors due to viewing angle deviation or misreading of the scale. It also has limited functionality and cannot support simultaneous bend and twist angle measurement.

In this embodiment, the positioning card slot 121 includes a first measuring slot 1211, a second measuring slot 1212 and a third measuring slot 1213. The first measuring slot 1211, the second measuring slot 1212 and the third measuring slot 1213 are all arranged at the bottom 12 and are all parallel to the width direction of the bottom 12. The depths and widths of the first measuring slot 1211, the second measuring slot 1212 and the third measuring slot 1213 are different; in addition, a fourth measuring slot 1214 is formed in the groove walls of the first measuring slot 1211, the second measuring slot 1212 and the third measuring slot 1213 along the length direction parallel to the bottom 12, and the depth of the fourth measuring slot 1214 is smaller than that of the first measuring slot 1211, the second measuring slot 1212 and the third measuring slot 1213.

[0036] In this example, please refer to Figure 4 again. The depths of the first measuring slot 1211, the second measuring slot 1212 and the third measuring slot 1213 gradually increase. The width of the second measuring slot 1212 is greater than the width of the first measuring slot 1211, and the width of the first measuring slot 1211 is greater than the width of the third measuring slot 1213. The widths and depths of the fourth measuring slots 1214 provided on the groove walls of the first measuring slot 1211, the second measuring slot 1212 and the third measuring slot 1213 are the same. Through the design with inconsistent widths and depths of the first measuring slot 1211, the second measuring slot 1212, the third measuring slot 1213 and the fourth measuring slot 1214, the rail angle measuring device is applicable to the measurement of various special-shaped rails, and the operation is convenient and fast.

[0038] Embodiment 2 This embodiment discloses a method for measuring the angle of a guide rail. The method for measuring the angle of a guide rail includes: clamping the positioning card slot 121 on the horizontal section of the guide rail, that is, the positioning card slot 121 is engaged with the horizontal section of the guide rail; starting the guide rail angle measuring device, the power supply assembly 3 provides electrical energy for the control unit 2, the angle sensor 4 measures the angle data of the horizontal section of the guide rail, and then the measurement personnel inputs a calibration instruction to the display assembly 5. The display assembly 5 receives the calibration instruction and transmits the received calibration instruction to the control unit 2. After receiving the calibration instruction, the control unit 2 zeros the angle data measured by the current angle sensor 4. The control unit 2 transmits the zeroing signal to the display assembly 5, and the display assembly 5 displays that the calibration is completed.

[0039] Then move the positioning card slot 121 to be clamped at the bent and twisted part of the guide rail. The measurement personnel inputs a measurement instruction to the display assembly 5. The display assembly 5 receives the measurement instruction and transmits the received measurement instruction to the control unit 2. After receiving the measurement instruction of the display assembly 5, the control unit 2 controls the angle sensor 4 to measure the angle data of the bent and twisted part of the guide rail. The angle sensor 4 measures the angle data of the bent and twisted part of the guide rail and transmits the measured angle data to the control unit 2. The control unit 2 conveys the received angle data to the display assembly 5, and the display assembly 5 then displays the measured angle data of the bent and twisted part of the guide rail.

[0040] Among them, after the measurement of the angle data of the horizontal section of the guide rail is completed, the angle data is zeroed. The purpose is that after the calibration is completed, the measurement value of the guide rail angle measuring device is adjusted to zero, so that before measuring the angle data of the bent and twisted part of the guide rail, the angle data displayed by the guide rail angle measuring device is zero. When measuring the angle data of the bent and twisted part of the guide rail, the angle data measured by the guide rail angle measuring device can be directly considered as the angle data of the bent and twisted part of the guide rail. The measurement personnel can directly obtain the angle data of the bent and twisted part of the guide rail, ensuring that the measurement result is intuitive, accurate and reliable.

[0041] Specifically, the startup power supply component 3 supplies power to the control unit 2, and the display component 5 displays the initial interface. The initial interface displays buttons such as calibration and measurement. Then, the positioning card slot 121 is fitted and clamped stably on the horizontal section of the guide rail, and the positioning card slot 121 is engaged with the horizontal section of the guide rail. Click on the position corresponding to the calibration button on the display component 5. After the display component 5 receives the calibration instruction, it transmits the calibration instruction to the control unit 2. After the control unit 2 receives the calibration instruction, it zeros the angle data measured by the current angle sensor 4. The control unit 2 transmits the zeroing signal to the display component 5, and thus the display component 5 displays that the calibration is completed.

[0042] Then, move the positioning card slot 121 to the bent and twisted part of the guide rail and engage it with the bent and twisted part of the guide rail. Click the measurement button on the display component 5. After the control unit 2 receives the measurement instruction from the display component 5, it controls the angle sensor 4 to detect the angle data at this time. The angle sensor 4 transmits the measured angle data to the control unit 2. The control unit 2 sends the obtained angle data to the display component 5, and the display component 5 displays the angle data of the bent and twisted part of the guide rail measured. Through a simple operation method, various special-shaped guide rails can be measured, and the test results can be directly read without the need for manual measurement and multiple readings for confirmation, and it is not easy to have human errors.
