[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 As shown, the utility model provides a technical solution: a speed detection mechanism for an overhead passenger device, comprising:

[0020] The frame 1 is provided with a conveying wheel 10 for conveying a steel cable to drive the overhead passenger device to move. A black annular plate 8 is provided on the top of the conveying wheel 10, and a reflective plate 9 is provided on the top of the black annular plate 8. A support plate 7 is provided on the side wall of the frame 1. A photoelectric sensor 6 is provided at a position corresponding to the reflective plate 9 on the top of the support plate 7. A PLC controller 5 and a display screen 4 are provided on the frame 1 in sequence. The photoelectric sensor 6 and the display screen 4 are respectively connected to the PLC controller 5, wherein an A / D converter is provided at the input end of the PLC controller 5, and a D / A converter is provided at the output end of the PLC controller 5. The photoelectric sensor 6 is electrically connected to the A / D converter, and the display screen 4 is electrically connected to the D / A converter. The design conveys the steel cable by rotating the conveying wheel 10, and detects the rotation of the conveying wheel 10. The dynamic speed can detect the conveying speed of the steel cable to the overhead passenger device. The conveying wheel 10 rotates to drive the black annular plate 8 to rotate, and the black annular plate 8 rotates to drive the reflector 9 to rotate. At the same time, the photoelectric sensor 6 works to emit a light beam to the black annular plate 8. Every time the black annular plate 8 rotates one circle, the photoelectric sensor 6 detects the reflector 9 thereon and sends the detected signal to the PLC controller 5. The PLC controller 5 converts the signal into a speed and displays it on the display screen 4, which is convenient for detecting the speed of the conveying wheel 10, and then plays a role in facilitating the detection of the speed of the overhead passenger device transported by the steel cable. The speed of the conveying wheel 10 is adjusted to a suitable range by observing the speed on the display screen 4, so that the speed of the overhead passenger device transported by the steel cable is adjusted to a suitable range, and the use effect is good.

[0021] Reference Figure 1 A through hole is provided at the bottom of the support plate 7 for allowing the light of the photoelectric sensor 6 to pass through. This design uses the through hole to facilitate the light passing through the through hole when the photoelectric sensor 6 is working, thereby facilitating the detection of the rotating reflector 9.

[0022] Reference Figure 2 and Figure 3A stop column 12 is symmetrically arranged on the top of the conveying wheel 10, and a stop hole 11 matching the stop column 12 is symmetrically opened at the bottom of the black annular plate 8. This design improves the stability of the connection between the black annular plate 8 and the conveying wheel 10 by using the stop column 12 to connect with the stop hole 11, and prevents the side slip between the two from affecting the detection accuracy.

[0023] Reference Figure 1 and Figure 2 The outer diameter of the black annular plate 8 matches the outer diameter of the conveying wheel 10, which improves the rationality of the design.

[0024] Reference Figure 3 The side wall of the conveying wheel 10 is provided with an annular groove 101 for conveying the steel cable, and the conveying wheel 10 is provided with an avoidance hole connected to the annular groove 101. A threaded hole 15 connected to the avoidance hole is provided at a position corresponding to the top of the conveying wheel 10 and the bottom of the black annular plate 8. A fixing bolt 14 is provided inside the threaded hole 15, and the head of the fixing bolt 14 is completely embedded in the avoidance hole. This design facilitates the connection and fixation between the black annular plate 8 and the conveying wheel 10 by using the fixing bolt 14 to connect with the threaded hole 15. By using the head of the fixing bolt 14 to be completely embedded in the avoidance hole, the conveying of the steel cable by the annular groove 101 of the conveying wheel 10 is not affected to avoid interference, thereby facilitating the connection and fixation between the black annular plate 8 and the conveying wheel 10.

[0025] Reference Figure 1 A driving motor 2 and a reducer 3 are sequentially arranged on the top of the frame 1. A coupling 21 is arranged between the output shaft of the driving motor 2 and the input shaft of the reducer 3. The conveying wheel 10 is connected to the output shaft at the bottom of the reducer 3. This design drives the driving motor 2 to drive the coupling 21 to rotate, and the coupling 21 rotates to drive the reducer 3 to rotate, and the reducer 3 rotates to drive the conveying wheel 10 to rotate, so that it is convenient to adjust the speed of the conveying wheel 10 by observing the speed on the display screen 4, so that the speed of the overhead passenger device transported by the steel cable is adjusted to an appropriate range, and the use effect is good. Among them, the driving motor 2, the reducer 3 and the coupling 21 are all existing technologies.

[0026] Reference Figure 1-Figure 3As an embodiment of the present invention: when it is necessary to detect the speed of the overhead passenger device, the staff drives the coupling 21 to rotate by operating the driving motor 2, the coupling 21 rotates to drive the reducer 3 to rotate, the reducer 3 rotates to drive the conveying wheel 10 to rotate, the conveying wheel 10 rotates to convey the steel cable, and the conveying speed of the steel cable to the overhead passenger device can be detected by detecting the rotation speed of the conveying wheel 10. The conveying wheel 10 rotates to drive the black annular plate 8 to rotate, and the black annular plate 8 rotates to drive the reflector 9 to rotate, and at the same time the photoelectric sensor 6 works to emit a light beam through the through hole to the black annular plate 8. On the plate 8, the black annular plate 8 detects the reflective plate 9 thereon through the photoelectric sensor 6 every time it rotates one circle and sends the detected signal to the PLC controller 5. The PLC controller 5 converts the signal into a speed and displays it on the display screen 4, thereby facilitating the detection of the speed of the conveying wheel 10, and then facilitating the detection of the speed of the overhead passenger device transported by the steel cable. The speed change is observed through the display screen 4, and the speed of the conveying wheel 10 is adjusted to an appropriate range, thereby adjusting the speed of the overhead passenger device transported by the steel cable to an appropriate range. The use effect is good, which improves the practicality of the utility model.
