[0026] like Figures 1 to 2 As shown, an elevator speed governor detector includes a main support sleeve 1. A connecting seat 2 for fixed connection with a speed governor bracket is fixedly provided at the bottom of the main support sleeve 1. A sliding column 3 is slidably provided in the main support sleeve 1. A first positioning component is fixedly provided between the sliding column 3 and the main support sleeve 1. A sliding plate 4 is slidably provided at the top of the sliding column 3 in a horizontal direction. A second positioning component is fixedly provided between the sliding plate 4 and the sliding column 3. A laser speed measuring component is fixedly provided at the end of the sliding plate 4.

[0027] Specifically, the connecting seat 2 on this device is connected to the metal bracket of the elevator speed governor. After connection, the main support sleeve 1 is aligned with the connecting seat 2. Then, the sliding column 3 is inserted into the main support sleeve 1. By changing the length of the sliding column 3 in the main support sleeve 1, the height of the laser speed measuring component is changed. Then, the sliding plate 4 is fixedly connected to the sliding column 3. By changing the connection position between the sliding plate 4 and the sliding column 3, the horizontal position of the laser speed measuring component is adjusted so that the laser speed measuring component can reach the position of the speed governor wheel and thus detect the speed of the speed governor wheel, achieving the effect of adapting to different models of speed governors. In this embodiment, by fixing the laser speed measuring device to the speed governor bracket through the sliding plate 4, sliding column 3, main support sleeve 1, and connecting seat 2, the manual operation of holding the instrument is eliminated, reducing detection errors. At the same time, by adjusting the position of the laser speed measuring component through the first positioning component and the second positioning component, this device can meet the needs of various models of speed governors, making it suitable for a wide range of applications.

[0028] The connecting seat 2 is L-shaped, and the bottom of the main support sleeve 1 is fixedly provided with a plug-in part 5. The top of the connecting seat 2 is plugged into the plug-in part 5, and the end of the connecting seat 2 is fixedly connected to the bracket of the speed limiter. Specifically, the main support sleeve 1 is connected to the plug-in part 5, which is simple to operate and can remain stable under the action of gravity.

[0029] The first positioning component includes a first bolt 6 and a first insertion hole 7 that mates with the first bolt 6. The first insertion hole 7 extends through the main support sleeve 1 and the sliding column 3. Multiple first insertion holes 7 are arranged in a linear array along the sliding direction on the sliding column 3. Specifically, by engaging different first insertion holes 7 on the sliding column 3 with the first bolt 6, the height of the laser velocity measuring component can be adjusted.

[0030] The second positioning component includes a limiting plate 8 and a second bolt 9. Both the limiting plate 8 and the sliding plate 4 have multiple second insertion holes 10 that mate with the second bolt 9. Specifically, the horizontal position of the laser velocity measuring component is adjusted by cooperating with the second bolt 9 and the second insertion holes 10 at different positions on the sliding plate 4 and the limiting plate 8.

[0031] The laser speed measuring component includes a laser emitter 11 and a laser receiver 12, with a distance adjustment device between them. Specifically, the speed limiter wheel is typically hollow, and the laser emitter 11 and laser receiver 12 are placed on either side of the speed limiter wheel. When the speed limiter wheel rotates, the frequency of the laser emitted by the laser emitter 11, received by the laser receiver 12, can indirectly determine the speed of the speed limiter wheel. The distance adjustment device can change the distance between them to accommodate speed limiters of different widths.

[0032] A mounting base 13 is fixedly mounted at the end of the slide plate 4. A first mounting plate 14 is fixedly mounted on the mounting base 13, and a second mounting plate 15 is slidably mounted on the mounting base 13. The laser emitting end 11 and the laser receiving plate 12 are respectively fixedly mounted on the first mounting plate 14 and the second mounting plate 15. The distance adjustment device includes a slide rail 16 and a lead screw 17. The lead screw 17 is threadedly connected to the mounting base 13, and the second mounting plate 15 is slidably connected to the slide rail 16. The end of the lead screw 17 is rotatably connected to the second mounting plate 15. Specifically, when adjusting the distance between the two, the lead screw 17 pushes or pulls the second mounting plate 15 to slide on the slide rail 16, thereby achieving the effect of adjusting the distance between the laser emitting end 11 and the laser receiving plate 12.

[0033] Several magnetic components 18 are fixedly provided at the end of the connecting seat 2, and the magnetic components 18 are attracted to the bracket of the speed limiter. Specifically, the bracket of the speed limiter is usually made of iron, so the magnetic components 18 can achieve a good connection effect. In addition, suction cups, grippers and other connection methods can also be used here, and there is no limitation.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
