[0002] With the acceleration of modern urbanization, high-rise buildings have sprung up like mushrooms after a rain. As an important tool for vertical transportation, the safety and operating efficiency of elevators have become the focus of attention from all walks of life. The complexity of the elevator system and the diversity of the operating environment make the daily inspection and maintenance of elevators particularly important. In particular, the elevator rails, as key components that support and guide the elevator car to move up and down, their deformation or wear directly affects the operating stability of the elevator and the safety of passengers.

[0003] At present, among the elevator detection equipment on the market, photoelectric sensors are a more common type. Photoelectric sensors mainly use the principle of photoelectric effect to indirectly evaluate the status of components such as slide rails by detecting the number and time of light beam blocking during elevator operation. When the position or state of elevator components changes, the light beam will be blocked or reflected, thereby triggering the sensor to generate a corresponding electrical signal, thereby realizing the monitoring of the elevator operation status.

[0004] However, photoelectric sensors are easily affected by dust. In the elevator operating environment, the accumulation of dust may block the sensor's beam path or change the reflection characteristics of the beam, causing the sensor to falsely report or miss a report, thereby affecting the accuracy of detection. Summary of the invention

[0005] The purpose of this application is to solve the problem that dust accumulation may block the sensor's light beam path or change the reflection characteristics of the light beam, causing the sensor to falsely report or miss a report, thereby affecting the accuracy of detection. This application provides an elevator detection method, system and device.

A follow-up slide groove is symmetrically provided at one end of the mounting bracket, and an arched extrusion bracket is slidably connected to the inside of the follow-up slide groove. One end of the elastic airbag pushes out of the interior of the mounting bracket and forms an elastic resistance with the arched extrusion bracket. One end of the arched extrusion bracket is rotatably connected to a resistance wheel. One end of the mounting bracket is symmetrically rotatably connected to a transmission rod, and one end of the transmission rod is fixedly connected to a cleaning brush head.

[0007] By adopting the above technical scheme, by setting the transmission component and the elastic airbag, the air pressure sensor, and the contact wheel for coordinated use, when the elevator is started and the contact wheel is driven to roll along the surface of the elevator slide rail, the transmission component is used to drive the cleaning brush head to rotate, so that the cleaning brush head cleans the dust and other foreign objects on the surface of the elevator slide rail, and then when the contact wheel passes through the wear or deformation area on the surface of the elevator slide rail, the contact wheel cooperates with the elastic characteristics of the elastic airbag to drive the arched extrusion frame to move along the length direction of the follower slide groove, thereby changing the strength of the resistance force applied to the elastic airbag by the arched extrusion frame, and then causing the elastic airbag to shrink or expand and deform, so that the air pressure inside the elastic airbag changes, and the controller analyzes the change value of the internal air pressure of the elastic airbag transmitted by the air pressure sensor to determine whether the elevator slide rail is dangerous to use, thereby facilitating the real-time cleaning of the surface of the elevator slide rail, thereby effectively reducing the influence of foreign objects such as dust on the surface of the slide rail on the slide rail monitoring data, and improving the monitoring accuracy of the elevator slide rail.

[0010] Furthermore, one end of the mounting frame is fixedly connected to laser scanner 1, and the other end of the mounting frame is fixedly connected to laser scanner 2, the mounting tube is installed between laser scanner 1 and laser scanner 2, and the controller is electrically connected to laser scanner 1 and laser scanner 2.

[0011] By adopting the above technical solution, when the controller receives the abnormal information transmitted by the air pressure sensor, the controller starts laser scanner one and laser scanner two at the same time, and uses laser scanner one and laser scanner two to scan and sample the abnormal area and normal area of ​​the elevator slide rail sensed by the air pressure sensor, and then uses the controller to compare and recheck the scanning data of laser scanner one and laser scanner two to determine whether there is any abnormality in the monitoring data, thereby effectively improving the monitoring accuracy of the device.

Then, when there are abnormalities in the data transmitted by the air pressure sensor 4 and the laser scanner 16 and the laser scanner 2 17, the controller 13 sends a control signal to the remote communication module 23 and the lighting 24 at the same time, so that the remote communication module 23 sends an alarm message to the remote staff, and turns on the lighting 24 to illuminate the abnormal area of ​​the elevator slide rail, so as to quickly guide the maintenance personnel.

An elevator detection method, characterized in that: The method comprises the following steps: S1: Fix the transmission rack (15) on the inner wall of the elevator shaft, move the mounting frame (1) to both sides of the elevator slide rail, adjust the transmission gear (14) and the transmission rack (15) to align, and make the mounting frame (1) drive the contact wheel (7) to form rolling contact with the elevator slide rail, and then use bolts to fix the connecting frame (10) to the top of the elevator; S2: When the elevator is running, the mounting frame (1) is driven to move along the inner wall of the elevator shaft, so that the transmission gear (14) is meshed with the transmission rack (15), and the transmission rack (15) is driven to rotate synchronously, so as to clean the dust and foreign matter on the elevator slide rail, and when the contact wheel (7) rolls along the elevator slide rail, the air pressure sensor (4) is used to monitor the air pressure change inside the elastic airbag (3) in real time, and transmit the data to the controller (13); S3: The controller (13) analyzes the air pressure change value. When it exceeds a predetermined value, the laser scanner 1 (16) and the laser scanner 2 (17) are started to scan and sample the elevator rail. The controller (13) compares the scan data and performs a re-inspection. S4: If an abnormality is found, the controller (13) sends a control signal to the remote communication module (23) and the lighting lamp (24), issues an alarm and provides guidance for maintenance.
