[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0031] As Figures 1-4The application relates to a speed measuring device for an escalator, which comprises a shell 1, a circuit board 2 arranged in the shell 1, a pair of fixing members 3 arranged at the bottom of the shell 1, a single-chip microcomputer 4 and an encoder 5 arranged on the circuit board 2, the encoder 5 being electrically connected with the single-chip microcomputer 4, a transmission gear connected with a shaft rod 6 of the encoder 5, and a speed measuring wheel 7 connected below the transmission gear and arranged between the pair of fixing members 3 and fixed at the bottom of the shell 1. When the pair of fixing members 3 are fixed to a handrail support of the escalator, the bottom of the speed measuring wheel 7 is abutted against the handrail or the main body of the escalator. In use, the escalator is operated, the handrail and the main body of the escalator are moved, and an elevator tester can move the pair of fixing members 3 of the speed measuring device downward from the top of the left handrail or the right handrail as a clamping device, so that the pair of fixing members 3 are clamped to the inner and outer sidewalls of the handrail support of the escalator, and the downward movement is stopped when the bottom of the speed measuring wheel 7 is abutted against the top of the left handrail or the right handrail of the escalator. Alternatively, the elevator tester can connect the pair of fixing members 3 of the speed measuring device to the inner sidewall of the left handrail or the right handrail of the escalator as a sliding connection device, and the bottom of the speed measuring wheel 7 is slidably arranged on the main body of the escalator, and the bottom of the speed measuring wheel 7 is abutted against the main body of the escalator. At this time, the power switch on the circuit board 2 is turned on, so that the single-chip microcomputer 4 and the encoder 5 in the speed measuring device are in a working state. Since the left handrail, the right handrail or the main body of the escalator is moved, the speed measuring wheel 7 in contact with the left handrail, the right handrail or the main body of the escalator is rotated, the transmission gear connected with the speed measuring wheel 7 is rotated, the encoder 5 connected with the transmission gear through the shaft rod 6 can count the rotation times of the speed measuring wheel 7, and the single-chip microcomputer 4 can calculate the speed of the left handrail, the right handrail or the main body of the escalator based on the counting result, the measurement time and the radius of the speed measuring wheel 7 and a calculation formula.

[0032] From the above description, it can be seen that the application achieves the following technical effects:

[0033] In the embodiment of the application, the pair of fixing members 3 are arranged in the shell 1, the bottom of the speed measuring wheel 7 can be abutted against the handrail support or the main body of the escalator when the pair of fixing members 3 are fixed to the handrail support or the main body of the escalator, the operation, calculation and other functional components are reduced, and the personnel need not hold the device, so that the cost of the detector is reduced, the operation is convenient, the technical effect of reducing the cost of the detector and the technical problem of high cost and inconvenient operation are solved.

[0034] Preferably, the fixing member 3 comprises a clamping rod 8 and a rubber sleeve 9, wherein the rubber sleeve 9 is sleeved on the clamping rod 8, and the side of the rubber sleeve 9 in contact with the handrail support is provided with an anti-skid layer 10; the preliminary fixation of the device on the inner and outer side walls of the handrail support can be achieved by a pair of clamping rods 8, and the speed measuring wheel 7 is arranged on the top of the handrail, but due to the friction between the speed measuring wheel 7 and the top of the handrail, the device is easily moved with the handrail due to friction, so the rubber sleeve 9 is adopted to increase the friction between the clamping rod 8 and the inner and outer side walls of the handrail support, thereby avoiding the movement of the device with the handrail, and further avoiding measurement errors.

[0035] Preferably, the fixing member 3 further comprises a magnetic member 11, which is arranged in the hollow structure 12 of the clamping rod 8; the magnetic member 11 can further avoid the movement of the device with the handrail, thereby further avoiding measurement errors.

[0036] Preferably, the clamping rod 8 comprises a top rod 13 and a bottom rod 14, the top of the top rod 13 is fixed to the bottom of the shell 1, the top of the bottom rod 14 is hinged to the bottom of the top rod 13, and the hollow structure 12 is arranged in the bottom rod 14; when the bottom rod 14 is rotated to be parallel to the top rod 13, a pair of bottom rods 14 can be fixed to the handrail support of the escalator; when the bottom rod 14 is rotated to be perpendicular to the top rod 13, a pair of bottom rods 14 can be slidably arranged on the escalator body, and the side thereof is connected to the handrail support of the escalator; in order to achieve the clamping of a pair of clamping rods 8 on the inner and outer side walls of the handrail support, the bottom thereof is often designed to be lower than the bottom of the clamping rod 8, but if it is used to detect the speed of the escalator body, the speed measuring wheel 7 will be difficult to reach the escalator body, therefore the clamping rod 8 is designed to be rotatable about the top rod 13, so that when detecting the speed of the escalator body, the bottom rod 14 is only needed to be rotated to be perpendicular to the top rod 13, the bottom of the speed measuring wheel 7 is slightly lower than the bottom of the bottom rod 14 at this time, and is placed at the junction of the handrail support and the escalator body, a pair of bottom rods 14 are slidably arranged on the escalator body, and the side thereof is attracted to the inner side wall of the handrail support of the escalator by the magnetic member 11, so that the speed measuring wheel 7 can normally contact the escalator body for speed measurement, and through the improvement of the structure, it is ensured that one device can be adapted to the fixation for speed measurement of the handrail and the escalator body.

[0037] Preferably, the side of the bottom rod 14 is further provided with a suction cup 15, when the bottom rod 14 is rotated to be perpendicular to the top rod 13, a pair of bottom rods 14 can be fixed to the escalator body by the suction cup 15; in order to ensure that the device can be effectively fixed on the inner side wall of the handrail when detecting the speed of the escalator body, the suction cup 15 is arranged on the side of the bottom rod 14, and is attracted to the inner side wall of the handrail, thereby further improving the fixing reliability.

Further, the wireless communication device 16 is a Bluetooth communication device. Since the escalator is always in motion, a wired communication connection often needs a data line long enough, and a slight negligence can easily cause the data line to be pulled off due to the long distance. In order to avoid this situation, the wireless communication device 16 is integrated on the circuit board 2, and the detected speed is sent to the host computer 17 through a wireless manner, and the host computer 17 completes the calculation of the synchronization rate of the handrail and the escalator body.

[0039] In another alternative embodiment, the circuit board 2 is further provided with a communication interface 18, which is electrically connected with the single-chip microcomputer 4 and communicatively connected with the host computer 17 through a data line for calculating the synchronization rate. In some special scenarios, the communication interface 18 and the data line can be used to transmit the measured speed to the host computer 17 for calculating the synchronization rate.

[0040] The application also relates to an escalator synchronization rate detection system, which comprises three speed detection devices for an escalator, and a host computer 17 communicatively connected with the three speed detection devices, wherein one speed detection device is slidably arranged on an escalator body of the escalator, and the side part thereof is connected with a handrail support of the escalator; and the other two speed detection devices are arranged on left and right handrail supports of the escalator, respectively.

Obviously, for those skilled in the art, various modifications and variations can be made to the application without departing from the spirit and principle of the application.
