[0024] In this embodiment, when in use, the linear rail 201, the angle rotation mechanism 202, the three-dimensional laser scanner 203, the camera 204, the forward and reverse motor 205, the climbing motor 311, the laser rangefinder 315, the electric push rod 502, the wireless communication device 8, the lighting lamp 9, the PLC controller 7 and the battery 10 are electrically connected, and the battery 10 is used to power other devices, and the PLC controller 7 is wirelessly connected to the external control terminal through the wireless communication device 8. The angle rotation mechanism 202 and the linear rail 201 are both existing mature technologies, and will not be described in detail here. The camera 204 and the three-dimensional laser scanner 203 are started. The three-dimensional laser scanner 203 emits a laser beam to the shaft wall, measures the time from the laser being emitted to being reflected and received, and calculates the distance from the scanner to each point on the shaft wall according to the speed of light. By scanning at different positions and angles, a large amount of distance data is obtained to form point cloud data, and then after calculation and processing by the PLC controller 7, a three-dimensional model of the shaft is constructed, thereby obtaining the contour information of the shaft. The camera 204 uses the optical imaging principle to image the scene inside the shaft on the photosensitive element of the camera 204 to form an image. The PLC controller 7 analyzes and processes the image. For example, the edge detection algorithm can identify the edge of the shaft wall, and the contour extraction algorithm can extract the contour of the shaft. The four lighting lamps 9 are started to provide sufficient brightness for the measurement. By starting the linear track 201, the angle rotation mechanism 202 can be driven to move back and forth, driving the camera 204 and the three-dimensional laser scanner 203 to move back and forth to measure different positions. By starting the angle rotation mechanism 202, the camera 204 and the three-dimensional laser scanner 203 can be driven to rotate angles to achieve different measurements. By starting the forward and reverse motors 205, the turntable 206 is driven to rotate, and the linear track 201, the angle rotation mechanism 202, the camera 204 and the three-dimensional laser scanner 203 are further driven to rotate, so that rotation measurement can be performed on the horizontal plane, further expanding the coverage of the measurement. Under the action of the measuring component 2, it is convenient to adjust the measuring direction and measuring position, observe and scan from different angles, obtain more comprehensive data, not only can measure different positions in the well, but also can focus on scanning and detailed measurement of specific areas when necessary, obtain richer data information, and improve overall measurement efficiency. When it is necessary to measure a high position, start the two electric push rods 502, push the two moving plates 503 to move outward, and push the limit rods 504 on both sides to move outward, so that they pass through the corresponding annular groove 310 and enter the limit groove 408, thereby limiting the climbing gear 309 to prevent the climbing gear 309 from being staggered with the first climbing tooth 401, the second climbing tooth 402 or the third climbing tooth 403 during the subsequent rotation process, affecting the stability of the moving seat 1, thereby affecting the accuracy of the measurement result.Then, the climbing motor 311 is started, and the output end of the climbing motor 311 drives the connected limit shaft 303 to rotate counterclockwise, and drives the rotating shaft 304, the driving gear 305 and the first connecting gear 302 on the left to rotate counterclockwise at the same time. Under the rotation of the left driving gear 305, the meshing right driving gear 305 rotates clockwise, and drives the rotating shaft 304, the limit shaft 303 and the first connecting gear 302 on the right to rotate clockwise. Through the left and right chains 306, the second connecting gear 307 and the rotating rod 308 on the left are driven to rotate counterclockwise, and the second connecting gear 307 and the rotating rod 308 on the right are driven to rotate clockwise, and further drive the climbing gears 309 on both sides to rotate upward on the first climbing tooth 401, the second climbing tooth 402 and the third climbing tooth 403 at the same time, and further drive the moving seat 1 to move upward, thereby driving the measuring component 2 to move upward to adjust its height position. When the climbing component 3 is started, the laser rangefinder 315 is started at the same time. The laser rangefinder 315 will emit a beam of laser through the detection hole 316 to the bottom surface of the shaft, and by receiving the reflected laser, the distance between the entire measuring device and the bottom surface of the shaft is calculated, and the distance is transmitted to the PLC controller 7. The PLC controller 7 transmits the data to the control terminal by wireless means, and the staff can see the distance data between the measuring device and the bottom surface of the shaft through the control terminal. As the moving seat 1 moves upward, the distance between the measuring device and the bottom surface of the shaft will change. When the distance data meets the requirements of the staff, that is, the measuring device moves to the height position to be measured, the climbing motor 311 is turned off, so that the measuring device stays there and measures the place. Ultrasonic sensors 317 are symmetrically installed on both sides of the auxiliary plate at the center of the front surface of the linear track 201. The two ultrasonic sensors 317 are started, and two ultrasonic pulses are emitted to the two sides of the well. When the ultrasonic wave encounters the reverse surface of the well, reflection occurs. The sensor receives the returned reflected wave, and measures the distance to the well walls on both sides according to the time difference between the ultrasonic wave emission and reception. The two are added to obtain the well width. The forward and reverse motors 205 in the measuring component 2 can drive the turntable 206 and the linear track 201 to rotate, thereby driving the two ultrasonic sensors 317 to rotate together, so as to facilitate the measurement of the width of the other two opposite sides inside the well. Through the climbing component 3, the height position of the measuring component 2 can be adjusted, and different heights inside the well can be measured, and the well width dimensions at different positions can also be measured. There is no need to install multiple measuring devices, and there is no need to perform multiple debugging and calibration. Under the automatic climbing of the climbing component 3, there is no need to repeatedly disassemble and assemble the measuring device, and the operation process is simpler, saving time and manpower, and improving work efficiency.The invention solves the problem that when it is necessary to measure at different heights in the elevator shaft, multiple measuring devices need to be installed and debugged and calibrated separately, which makes the operation process cumbersome and complicated, or after completing a measurement, the measuring device is removed from the measuring position and installed at another position, which increases the workload of disassembly and installation, consumes more time and greatly reduces work efficiency.

[0026] In this embodiment, when in use, the inner walls of the limiting grooves 408 at the first climbing teeth 401 and the third climbing teeth 403 are provided with embedded threaded holes, such as Figure 5As shown, the first climbing tooth 401 is installed on the inner wall of the well through bolts, and then the second climbing tooth 402 is pushed to the top of the first climbing tooth 401, so that the clamping rod 405 is inserted into the clamping groove 406 on the side of the first climbing tooth 401, which can not only realize the connection between the first climbing tooth 401 and the second climbing tooth 402, but also play a limiting role, so that the upper and lower limiting grooves 408 are aligned, and the subsequent sliding of the limiting rod 504 in the limiting groove 408 is not affected. According to the depth of the well, the corresponding number of second climbing teeth 402 is selected, and multiple second climbing teeth 402 are connected together according to the above installation method. Finally, the third climbing tooth 403 is installed and fixed by bolts. At this time, the first climbing tooth 401, the second climbing tooth 402 and the third climbing tooth 403 form a vertical track, which is convenient for the subsequent climbing movement of the climbing component 3, thereby adjusting the height position of the measuring component 2. The first climbing tooth 401, the second climbing tooth 402 and the third climbing tooth 403 are spliced ​​and can be disassembled into several smaller parts for easy transportation. For elevator shafts of different heights, the total length can be adjusted by increasing or decreasing the number of splicing sections of the second climbing tooth 402, so as to meet the measurement requirements of different shafts and be more flexible and applicable. After the splicing assembly 4 is installed, the moving seat 1 is pushed to move so that the climbing gear 309 is inserted into the first climbing tooth 401. A tooth block 407 is inserted at the bottom of the two first climbing teeth 401 at the rear position, and is bolted on the first climbing tooth 401. When two of the climbing gears 309 are in contact with the two tooth blocks 407, the moving seat 1 cannot be pushed further. At this time, the limit groove 408 is aligned with the annular groove 310. Under the positioning effect of the tooth block 407, the limit rod 504 in the limit assembly 5 is conveniently inserted into the limit groove 408 accurately.

[0028] In this embodiment, when in use, the image capture module 11 captures images of the interior of the elevator shaft, records the structure of the shaft, component status, presence or absence of foreign matter, and other information, provides intuitive visual data for subsequent analysis and judgment, and helps identify key features and abnormal conditions in the shaft. The three-dimensional scanning module 12 collects three-dimensional spatial data of the elevator shaft, obtains accurate information such as the shape, size, and spatial position relationship of the shaft, and is used to construct a three-dimensional model of the shaft to detect whether the spatial structure of the shaft meets the standards and design requirements. Then the image capture module 11 and the three-dimensional scanning module 12 transmit the image data and the three-dimensional data to the data acquisition module 1301, which performs preliminary sorting and caching of the data to ensure the integrity and accuracy of the data in preparation for subsequent analysis and processing. The data analysis module 1302 performs in-depth analysis and processing on the collected images and three-dimensional data, performs preprocessing on the image data, removes noise interference in the image, performs grayscale and normalization operations, converts the color image into a grayscale image, unifies the brightness and contrast of the image, and uses the edge detection algorithm to extract the edge information of the shaft structure, such as the edge of the shaft wall and the edge of the guide rail. The corner point detection algorithm is used to identify the key corner points in the shaft, and the image is segmented into different regions through the region segmentation algorithm, such as distinguishing the shaft wall and the car. Based on template matching or deep learning algorithms, the elevator components and structures in the image are identified, such as identifying floor signs, leveling switches, etc. Through geometric calculations, the actual size and distance of objects in the shaft are calculated based on the known size and proportional relationship in the image. The three-dimensional data is pre-processed with point cloud, outliers and noise points in the three-dimensional point cloud data are removed, and the data is smoothed; through coordinate transformation and registration algorithms, the point cloud data collected at different positions and angles are unified into the same coordinate system, and a triangular mesh reconstruction algorithm is used to construct a three-dimensional surface model of the well according to the point cloud data, intuitively display the shape and structure of the well, and then calculate the spatial dimensions of the well, such as height, width, depth, etc.; analyze the verticality, flatness, inclination and other indicators of the well; and detect whether there are obstacles or spatial anomalies in the well. Among them, the automatic learning module 1303 is based on machine learning algorithms such as neural networks and decision trees, and trains a large amount of labeled data, adjusts the parameters and weights of the model, so that the model can accurately classify, predict and analyze new data, and improves the precision and accuracy of measurement by continuously optimizing the model and algorithm of data analysis, and automatically adapts to different well environments and measurement requirements. The wireless communication module 15 transmits the data processed by the central processing module 13 to the intelligent terminal module 16 through wireless signals, so that the staff can view the measurement results and data in real time and realize remote control and monitoring.The instruction sending module 1601 converts the instructions input by the operator through buttons, touch screens, etc. into digital signals, encapsulates and encodes them according to the communication protocol, and sends the signals to the central processing module 13 through the wireless communication module 15. The result display module 1602 receives the data from the central processing module 13, and displays the measurement results, analysis reports, image data and other information processed by the central processing module 13 to the operator in an intuitive manner, including numbers, charts, images, three-dimensional models, etc., so that the operator can view and understand the measurement results. The fill light module 14 provides sufficient light inside the elevator shaft to ensure that the image capture module 11 can capture clear images, and the three-dimensional scanning module 12 can accurately collect data and eliminate the influence of shadows.

[0029] The effect and working principle of the whole mechanism are as follows: the first climbing tooth 401 is installed on the inner wall of the well by bolts, and then the second climbing tooth 402 is pushed to the top of the first climbing tooth 401, so that the clamping rod 405 is inserted into the clamping groove 406 on the side of the first climbing tooth 401, and finally the third climbing tooth 403 is installed and fixed by bolts, at which time the first climbing tooth 401, the second climbing tooth 402 and the third climbing tooth 403 form a vertical track. Push the moving seat 1 to move, so that the climbing gear 309 is inserted into the first climbing tooth 401, and when two of the climbing gears 309 are in contact with the two clamping tooth blocks 407, the moving seat 1 cannot be pushed further. The camera 204 and the three-dimensional laser scanner 203 are started. The three-dimensional laser scanner 203 emits a laser beam to the shaft wall, measures the time from the laser being emitted to being reflected and received, calculates the distance from the scanner to each point on the shaft wall according to the speed of light, and obtains a large amount of distance data by scanning at different positions and angles to form point cloud data. The camera 204 uses the principle of optical imaging to image the scene inside the shaft on the photosensitive element of the camera 204 to form an image. The PLC controller 7 analyzes and processes the data to extract the contour of the shaft. By starting the linear track 201, the angle rotation mechanism 202 can be driven to move back and forth, driving the camera 204 and the three-dimensional laser scanner 203 to move back and forth to measure different positions. By starting the angle rotation mechanism 202, the camera 204 and the three-dimensional laser scanner 203 can be driven to rotate angles to achieve different measurements. By starting the forward and reverse motors 205, the turntable 206 is driven to rotate, and the linear track 201, the angle rotation mechanism 202, the camera 204 and the three-dimensional laser scanner 203 are further driven to rotate, so that rotation measurement can be performed on the horizontal plane. When it is necessary to measure a high position, the two electric push rods 502 are started to push the two moving plates 503 outward, and the limiting rods 504 on both sides are pushed outward to pass through the corresponding annular grooves 310 and enter the limiting grooves 408, thereby limiting the climbing gear 309. Then start the climbing motor 311, driving the limiting shaft 303, rotating shaft 304, driving gear 305 and first connecting gear 302 on the left to rotate counterclockwise, while the driving gear 305 on the right drives the rotating shaft 304, limiting shaft 303 and first connecting gear 302 on the right to rotate clockwise, through the left and right chains 306, driving the second connecting gear 307 and rotating rod 308 on the left to rotate counterclockwise, and the second connecting gear 307 and rotating rod 308 on the right to rotate clockwise, further driving the climbing gears 309 on both sides to rotate upward on the first climbing tooth 401, the second climbing tooth 402 and the third climbing tooth 403 at the same time, further driving the moving seat 1 to move upward, thereby driving the measuring component 2 to move upward to adjust its height position.At the same time, the laser rangefinder 315 is started to calculate the distance between the entire measuring device and the bottom surface of the well, and the distance is transmitted to the PLC controller 7, which transmits the data to the control terminal by wireless. As the moving seat 1 moves upward, the distance between the measuring device and the bottom surface of the well will change. When the distance data meets the requirements of the staff, that is, when the measuring device moves to the height position to be measured, the climbing motor 311 is turned off, so that the measuring device stays at this place and measures the place. Two ultrasonic sensors 317 are started, and two ultrasonic pulses are emitted to the two sides of the well respectively. When the ultrasonic wave encounters the reverse surface of the well, reflection occurs. The sensor receives the returned reflected wave, and according to the time difference between the ultrasonic wave emission and reception, the distance to the well wall on both sides is measured respectively, and the two are added to obtain the well width. Through the forward and reverse motors 205 in the measuring assembly 2, the turntable 206 and the linear track 201 can be driven to rotate, thereby driving the two ultrasonic sensors 317 to rotate together, so as to facilitate the width measurement of the other two opposite sides inside the well.

[0030] Among them, the linear rail 201, the angle rotation mechanism 202, the three-dimensional laser scanner 203, the camera 204, the forward and reverse motor 205, the climbing motor 311, the laser rangefinder 315, the electric push rod 502, the wireless communicator 8, the lighting lamp 9, the PLC controller 7 and the battery 10 are all existing technologies, and their components and usage principles are all public technologies, which will not be explained in detail here.
