Description

Technical Field

[0001] This invention relates to the field of elevator inspection, and in particular to an elevator guide rail inspection and management device and method. Background Technology

[0002] With the advancement of industrial technology, elevators have become indispensable equipment in many offices, entertainment venues, and residences. An elevator consists of two vertically aligned guide rails and an elevator car installed between them. The verticality and parallelism of the guide rails not only affect the comfort and lifespan of the elevator but can also pose certain safety hazards. Therefore, the inspection and management of elevator guide rails is particularly important.

[0003] Existing technology CN118323986B provides an elevator guide rail inspection device, including a guide rail climbing robot and a detection device. Guide rail climbing robots are installed on both elevator guide rails. Each robot has an upper outer car body, a lower outer car body, an upper inner car body, and a lower inner car body that move vertically along the guide rails. A laser rangefinder is installed on one upper inner car body, and a laser reflector is installed on the other upper inner car body. Two-dimensional PSD position detectors are installed on both lower inner car bodies, and a plumb line mounting frame is arranged on both upper inner car bodies, with a plumb line mounted on the frame. When the elevator car stops after reaching a certain height, a rope lifting device drives the lower inner car body to move up and down along the elevator guide rails. During the movement of the lower inner car body, the offset of the laser spot on the two-dimensional PSD position detector can be used to immediately detect the verticality deviation of the elevator guide rails.

[0004] However, this device relies on the movement of the elevator car to drive the guide rail climbing robot. During the operation of the elevator car, vibrations and swaying are inevitable. These vibrations and swaying are transmitted to the robot. After the car stops, the laser plumb line will still sway and continue to act for a period of time, which will reduce the measurement accuracy of the elevator guide rail to a certain extent. Moreover, the segmented measurement adopted by the car drive lacks data continuity, which affects the assessment of the true state of the track. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an elevator guide rail detection and management device and method, which uses a self-driven mechanism to carry a laser plumb line and a PSD position detector for detection, avoiding the influence of car swaying on the measurement results, and enabling dynamic measurement.

[0006] The objective of this invention is achieved through the following solution:

One end of the fourth insert rod is inserted into the limiting cylinder and extends upward through the limiting cylinder to be screwed to the second nut. The other end of the fourth insert rod is provided with a fourth telescopic seat. The fourth telescopic seat and the limiting cylinder are connected through the fourth elastic component. The fourth telescopic seat is provided with a drive motor, and the drive wheel is mounted on the drive motor. The insert rod drive mechanism can drive the fourth insert rod to make the drive wheel abut against the elevator guide rail.

[0024] In one embodiment, the elevator guide rail detection and management device further includes a dustproof protective cover and a dustproof protective plate;

[0025] The mounting base is equipped with a slide rail, and a dustproof protective plate is located at one end of the slide rail. The dustproof protective cover is slidably connected to the slide rail. When performing testing, the dustproof protective cover and the dustproof protective plate abut against each other so that the laser plumb line and PSD position detector are located inside the dustproof protective cover.

[0026] In one embodiment, the elevator guide rail detection and management device further includes a protective mechanism, which includes a protective platform, a first drive arm, a second drive arm, a steering platform, and a tightening mechanism.

[0027] The protective platform is mounted on the mounting base.

[0028] The tightening mechanism is installed on the turntable and is used to pre-tighten the connecting parts of the elevator guide rail; the turntable is equipped with a camera mechanism and a marking mechanism, and the marking mechanism is equipped with a marking control valve;

[0029] The third, fourth, and fifth drive mechanisms, the tightening mechanism, and the marking control valve are all electrically connected to the controller and power supply. The camera mechanism is electrically connected to the controller to send the captured image information of the elevator guide rail connection to the power and control device.

[0030] In one embodiment, the laser plumb line includes an outer spherical shell, an inner sphere, a vertical stabilizing block, and a laser emitter;

[0031] The outer spherical shell is mounted on a vertical mounting bracket. The outer spherical shell and the inner sphere are slidably connected by multiple ball bearings. The upper and lower ends of the outer spherical shell are open. The vertical stabilizing block is connected to the inner sphere through the lower end opening of the outer spherical shell. The laser emitter is embedded in the vertical stabilizing block. The vertical stabilizing block is used to drive the laser emitted by the laser emitter to always be vertically downward.

[0033] In one embodiment, the elevator guide rail detection and management device further includes a distance detection mechanism, which includes a laser rangefinder and a laser reflector. The laser rangefinder and the laser reflector are respectively mounted on two mounting bases connected to the pressure stabilization mechanism, and the laser rangefinder points towards the laser reflector.

[0034] The distance detection mechanism is electrically connected to the controller and the power supply, respectively.

[0035] On the other hand, an elevator guide rail inspection and management method is provided, including:

[0037] Start the laser plumb line to obtain the first laser image on the PSD position detector, start the laser rangefinder to obtain the second laser image of the track spacing of the elevator guide rails obtained by the laser reflector on the laser rangefinder;

[0038] By controlling the first drive mechanism on the two measuring vehicles to drive the measuring vehicles up or down synchronously, the first laser image and the second laser image captured by the PSD position detector and the laser rangefinder during the measurement process are recorded.

[0039] The first and second laser images are processed to obtain and save the elevator guide rail verticality deviation curve and distance change deviation curve.

[0040] The system acquires images of the elevator guide rail connection points captured by a camera and pre-tightens loose connectors on the elevator guide rails using a tightening structure on the control and protection device.

[0041] After the pre-tightening process is completed, the pre-treated position is traced and marked by controlling the marking control valve on the marking mechanism.

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0043] 1. Design a measuring carriage with a first drive mechanism to realize the self-drive of the device instead of the elevator car drive method, so as to avoid the change in measurement accuracy caused by the shaking of the elevator car; and the self-drive measuring carriage has higher accuracy and can be adjusted at will to adjust the required measurement position. Combined with the second drive mechanism, the elevator guide rail is detected in real time during the movement to realize the dynamic measurement of the elevator guide rail.

[0044] 2. It adopts a retractable and controllable pressure stabilizing mechanism, which can adapt to different types of elevator guide rails and can always provide pressure to the measuring carriages on both sides, preventing the measuring carriages from falling off due to changes in the distance between the elevator guide rails.

[0045] 3. Design a dustproof protective cover between the laser plumb line and the PSD position detector to isolate dust in the elevator shaft and reduce the impact of dust in the elevator shaft on the measurement.

[0046] 4. The measuring vehicle is equipped with protective devices. During the inspection process, the camera can be used to conduct a preliminary inspection of the connection between the elevator guide rail and the elevator shaft. The tightening mechanism can be used to tighten the connection that is about to fall off to prevent the guide rail from falling off accidentally. At the same time, the marking mechanism can be used to mark the location so that maintenance personnel can quickly find the location that needs to be repaired during subsequent maintenance.

Detailed Implementation

[0058] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0059] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "parallel," "first," "second," "third," and similar expressions used in this document are for illustrative purposes only.

[0060] See Figure 1The present invention illustrates an elevator guide rail detection and management device provided in Embodiment 1 of the present invention, which includes at least two measuring vehicles 100, a pressurization and stabilization mechanism 200, a first drive mechanism 300, at least two vertical detection mechanisms 400, a power supply device 500, and a controller 600.

[0061] The measuring carriage 100 is used to install on the elevator guide rail. Two measuring carriages 100 are in contact with the two single-sided guide rails of the elevator guide rail in a one-to-one correspondence. Each measuring carriage 100 is equipped with a mounting base 110, and the mounting base 110 is provided with a plumb line mounting bracket 120.

[0062] The two ends of the pressure boosting and stabilizing mechanism 200 are respectively connected to two mounting seats 110 on different measuring vehicles 100; the pressure boosting and stabilizing mechanism 200 is used to drive the two measuring vehicles 100 to move away from each other, so that the two measuring vehicles 100 are pressed against the elevator guide rail respectively.

[0063] Specifically, the inspection work of the measuring carriage 100 in the elevator shaft is affected by external factors (such as airflow fluctuations and slight vibrations within the elevator shaft) and the offset of the elevator guide rails during movement. During the inspection process, it may sway or shift, posing a risk of derailment and falling. The pressure-boosting and stabilizing mechanism 200, on the one hand, ensures that the two measuring carriages 100 are in close contact with the elevator guide rails and applies pressure to resist the influence of external interference forces, enabling the measuring carriages 100 to maintain their structural stability in the complex shaft environment and ensuring the normal operation of the measuring equipment. On the other hand, it can adapt to elevator guide rails of different sizes within a certain range. When encountering smaller guide rails, the pressure boosting effect of the pressure-boosting and stabilizing mechanism 200 allows the measuring carriage 100 to better conform to the guide rail surface. Even if the guide rail is larger, by appropriately adjusting the pressure of the pressure-boosting and stabilizing mechanism 200, it can still ensure close contact between the measuring carriage 100 and the guide rail, thereby improving the compatibility of the entire elevator guide rail inspection and management device with different specifications of elevator guide rails.

[0064] The first drive mechanism 300 is provided on the measuring carriage 100, and the first drive mechanism 300 is used to drive the measuring carriage 100 to move along the extension direction of the elevator guide rail.

[0065] On the one hand, the measuring vehicle 100 can achieve self-driving inspection work through the first drive mechanism 300, without needing to be driven by the elevator car, thus avoiding the impact of elevator car swaying on the inspection accuracy of the measuring vehicle 100. On the other hand, the self-driving method achieved through the first drive mechanism 300 provides the measuring vehicle 100 with the possibility of adapting to various inspection environments and improving inspection safety. The self-driving measuring vehicle 100 can freely and accurately reach the predetermined measurement position. For example, during elevator non-operational hours, elevator inspection work before elevator car installation, or specific maintenance inspection windows, it can also autonomously select measurement paths and key areas, greatly improving the efficiency and focus of measurement work; and in case of emergency, it can quickly react by braking or adjusting the running direction, reducing the risk of accidents. In contrast, the existing measuring vehicle 100, which relies on the elevator car for drive, is limited by various factors of the elevator car (such as the operating parameters of the car itself, swaying during the movement, etc.), and therefore cannot adapt to different working environments or avoid dangerous accidents.

[0066] The two vertical detection mechanisms 400 are located on two mounting bases 110 belonging to different measuring vehicles 100, such as Figure 2 As shown, the vertical detection mechanism 400 includes a laser plumb line 410 and a PSD position detector 420. The laser plumb line 410 is mounted on a plumb line mounting bracket 120. A second drive mechanism 430 is provided on the side of the mounting base 110 away from the laser plumb line 410. The PSD position detector 420 is located on the second drive mechanism 430. The laser plumb line 410 points towards the PSD position detector 420. The second drive mechanism 430 can drive the PSD position detector 420 to move closer to or away from the laser plumb line 410.

[0067] Specifically, the PSD position detector 420 determines the light spot coordinates based on the photoelectric effect and works in conjunction with the laser plumb line 410 to detect the verticality of the elevator guide rail. In actual operation, the brightness inside the elevator shaft is complex and variable. When it is too bright, it is affected by background light interference; when it is too dark, it is affected by signal noise, both of which can make the light spot coordinates unclear. The second drive mechanism 430 precisely drives the PSD position detector 420 closer to or further away from the laser plumb line 410. On the one hand, this ensures the accuracy of imaging. When the brightness is too high, the distance between the laser plumb line 410 and the PSD position detector 420 is increased to reduce light interference; when it is dim, the distance between the laser plumb line 410 and the PSD position detector 420 is decreased to enhance the signal, thereby ensuring detection accuracy. On the other hand, the distance between the PSD position detector 420 and the laser plumb line 410 can be dynamically adjusted according to different measurement positions and environmental conditions to ensure accurate vertical detection. Whether at different heights on the guide rail or dealing with changes in brightness and dust within the shaft, it can be flexibly driven, enabling the measuring vehicle 100 to continuously and stably acquire elevator guide rail verticality data during movement. This allows for dynamic measurement of the elevator guide rail, providing a reliable basis for a comprehensive assessment of the guide rail condition and ensuring the safe operation of the elevator.

[0068] The power supply device 500 can be a municipal power source, a rechargeable battery, or a disposable battery, preferably a portable power source. The boosting and stabilizing mechanism 200, the first drive mechanism 300, and the vertical detection mechanism 400 are all electrically connected to the power supply device 500.

[0069] The controller 600 can be a microcontroller, etc. The boosting and stabilizing mechanism 200, the first driving mechanism 300 and the vertical detection mechanism 400 are all electrically connected to the controller 600.

[0070] The elevator guide rail detection and management device provided in Embodiment 1 of the present invention has the following usage steps:

[0071] First, two measuring carriages 100 are placed on the two elevator guide rails to be inspected. The controller 600 operates the pressure-stabilizing mechanism 200 to ensure the measuring carriages 100 are tightly fitted to the guide rails, applying pressure to firmly adhere them to the surface. Next, the laser plumb line 410 is activated. Based on the imaging of the PSD position detector 420, the second drive mechanism 430 is controlled to operate, changing the distance between the laser plumb line 410 and the PSD position detector 420 to obtain a clear laser image. Subsequently, the controller 600 controls the first drive mechanism 300 to synchronously drive the two measuring carriages 100 along the direction of the elevator guide rails, thereby detecting the verticality of the elevator guide rails. During the movement of the measuring carriages 100, the controller 600 dynamically adjusts the second drive mechanism 430 in real time, changing the distance between the laser plumb line 410 and the PSD position detector 420 to ensure clear imaging throughout the entire inspection process.

[0072] The beneficial effects of the elevator guide rail detection and management device provided in Embodiment 1 of the present invention are as follows:

[0073] The elevator guide rail detection and management device provided by this invention features a measuring carriage 100 equipped with a first drive mechanism 300, replacing the traditional elevator car drive with a self-driven mode. During daily operation, the elevator car inevitably sways due to factors such as carrying passengers and goods, starting and stopping, etc. This sway is directly transmitted to the measuring equipment, causing significant deviations in measurement accuracy. The self-driven measuring carriage 100 offers higher accuracy and can be freely adjusted to the desired measurement position. Combined with the second drive mechanism 430's real-time correction of the PSD position detector 420's position during movement, clear laser imaging is generated throughout the entire movement process. This allows for simultaneous detection while the elevator guide rail is moving, enabling the measuring carriage 100 to continuously and stably acquire elevator guide rail verticality data during movement. This achieves dynamic measurement of the elevator guide rail, providing a reliable basis for comprehensive evaluation of the guide rail condition and ensuring safe elevator operation.

[0074] Preferably, please refer to Figure 3 The pressurization and stabilization mechanism 200 includes a first push rod mechanism 210, a second push rod mechanism 220, and an angle adjuster 230;

[0075] The first push rod mechanism 210 and the second push rod mechanism 220 are respectively connected to two mounting seats 110 belonging to different measuring vehicles 100. The first push rod mechanism 210 and the second push rod mechanism 220 are connected through an angle adjuster 230. The angle adjuster 230 includes a protective housing 231 and a coupling 232 disposed in the protective housing 231. The first push rod mechanism 210 and the second push rod mechanism 220 are respectively located on opposite sides of the coupling 232.

[0076] Specifically, the coupling 232 ensures the connection between the first push rod mechanism 210 and the second push rod mechanism 220 while allowing for a certain angular deviation between them to accommodate the lateral offset of the elevator guide rail in its extension direction. This ensures that the first push rod mechanism 210 and the second push rod mechanism 220 consistently apply a downward pressure perpendicular to the guide rail to the measuring carriages 100 on both sides. This ensures the stable attachment of the measuring carriages 100 to the guide rail, preventing changes in pressure direction due to lateral offset of the guide rail. This reduces abnormal friction between the measuring carriages 100 and the guide rail caused by lateral pressure, protecting the components of the measuring carriages 100 and the surface of the guide rail, extending their service life, and ensuring measurement accuracy. Simultaneously, the use of the first push rod mechanism 210 and the second push rod mechanism 220 allows the pressure-boosting and stabilizing structure to flexibly adapt to elevator guide rails with different spacings. When facing guide rails with different spacing specifications, the length of the extended push rods of the two push rod mechanisms can be adjusted, allowing the measuring carriages 100 to closely adhere to the guide rails for testing regardless of the guide rail spacing, greatly improving the versatility and adaptability of the entire testing device.

[0077] It is understandable that the pressure-boosting and stabilizing mechanism 200 can be a combination of two hydraulic telescopic cylinders and a universal joint. Through hydraulic system adjustment, the extension and retraction lengths of the two hydraulic telescopic cylinders can be easily changed to adapt to elevator guide rails with different spacings, ensuring a tight fit between the measuring carriage 100 and the guide rail. The universal joint is similar to the coupling 232 in the angle adjuster 230; it allows the hydraulic telescopic cylinders to rotate flexibly within a certain angle range. When the elevator guide rail deviates left or right in the extension direction, the universal joint can adaptively adjust the angle. The pressure-boosting and stabilizing mechanism 200 can also be a combination of an electric lead screw and a ball joint structure. The electric lead screw is mounted on the corresponding mounting base 110 of the measuring carriage 100. Its high-precision lead screw transmission can accurately control the thrust and extension length. The extension and retraction of the lead screw is adjusted by the forward and reverse rotation of the motor, thereby adapting to the requirements of elevator guide rails with different spacings and ensuring good contact between the measuring carriage 100 and the guide rail. The ball joint mechanism replaces the angle adjuster 230. It is connected between the two electric lead screws. The ball joint can rotate and swing at a certain angle in various directions. When the elevator guide rail deviates to the left or right, the ball joint can automatically adjust its posture so that the force applied by the electric lead screw is always perpendicular to the guide rail and downward.

[0078] In one embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, a positioning wheel 130 and an anti-sway stabilizing mechanism 140 are connected to the mounting base 110. The positioning wheel 130 is used to abut against the rail head of the elevator guide rail. The anti-sway stabilizing mechanism 140 includes at least two first stabilizing frames 150 and at least two second stabilizing frames 160.

[0079] Two first stabilizing frames 150 are arranged sequentially at intervals along the axial direction of the positioning wheel 130 and are respectively located on opposite sides of the positioning wheel 130. A first pulley 151 is installed on the first stabilizing frame 150. The first pulley 151 is used to abut against the rail body of the elevator guide rail. The first stabilizing frame 150 is used to reduce the shaking phenomenon of the measuring carriage 100 caused by the deviation of the elevator guide rail. Two second stabilizing frames 160 are arranged sequentially at intervals along the axial direction of the positioning wheel 130 and are respectively located on opposite sides of the positioning wheel 130. A second pulley 161 is installed on the second stabilizing frame 160. The second pulley 161 is used to abut against the bottom of the elevator guide rail. The second stabilizing frame 160 is used to reduce the shaking phenomenon of the measuring carriage 100 caused by the deviation of the elevator guide rail.

[0080] Specifically, when the elevator guide rail deviates horizontally, i.e., when the rail body deviates, the interference force exerted by the elevator guide rail on the measuring carriage 100 will cause the measuring carriage 100 to sway horizontally. Through the cooperation of the first pulley 151 and the first stabilizer 150, the first pulley 151 can evenly distribute the force when bearing the interference force generated by the guide rail deviance, thereby effectively reducing the swaying transmitted to the measuring carriage 100 due to the guide rail deviance and ensuring the relative stability of the measuring carriage 100 in the horizontal direction. Similarly, when the elevator guide rail deviates in the direction of movement, i.e., when the bottom of the rail deviates, the cooperation of the second pulley 161 and the second stabilizer 160 can effectively reduce the swaying transmitted to the measuring carriage 100 due to the guide rail deviance, ensuring the relative stability of the measuring carriage 100 in the extension direction of the elevator guide rail.

[0081] Preferably, the first stabilizer 150 includes a first telescopic seat 152, a first insert rod 153, a first elastic component 154, a first nut 155, a second telescopic seat 156, and a second elastic component 158; two second stabilizers 160 are respectively disposed on both sides of the positioning wheel 130 perpendicular to the direction of movement, and the second stabilizer 160 includes a third insert rod 162, a third telescopic seat 163, and a third elastic component 164;

[0082] The mounting base 110 has multiple mounting through holes. One end of the first insertion rod 153 extends upward through one of the mounting through holes, passes through the mounting base 110, and is screwed to the first nut 155. The other end of the first insertion rod 153 is connected to the first telescopic seat 152. The mounting base 110 and the first telescopic seat 152 are connected by the first elastic member 154. The first telescopic seat 152 has a telescopic countersunk hole on the side facing the elevator guide rail body. The telescopic countersunk hole is inserted into one end of the second insertion rod 157. The other end of the second insertion rod 157 is connected to the second telescopic seat 156. The first telescopic seat 152 and the second telescopic seat 156 are connected by the second elastic member 158. The first pulley 151 is installed on the second telescopic seat 156.

[0083] One end of the third insertion rod 162 is inserted into one of the mounting through holes, and the other end of the third insertion rod 162 is connected to the third telescopic seat 163. The mounting seat 110 is connected to the third telescopic seat 163 through the third elastic component 164, and the second pulley 161 is mounted on the third telescopic seat 163. Preferably, the first elastic element, the second elastic element, and the third elastic element can be springs or elastic rubber pads.

[0084] Specifically, in actual elevator guide rail testing scenarios, different elevator guide rails may have certain height differences, or there may be local unevenness during guide rail installation. By adjusting the height of the pulley through the first telescopic seat 152, the distance between the first telescopic seat 152 and the mounting base 110 can be changed during installation through the first insert rod 153 and the first nut 155. At this time, the first elastic component 154 is compressed to provide pressure to the first telescopic seat 152. The pressure is transmitted to the first nut 155 through the first insert rod 153, so that the first nut 155 is pressed onto the mounting base 110, thereby ensuring that the first pulley 151 of the measuring carriage 100 can maintain good contact with the rail bodies of different elevator guide rails, thus adapting to different testing tasks.

[0085] Secondly, due to aging or deformation of the elevator, the measuring carriage 100 may be subjected to external impacts from the elevator guide rail during operation. The second telescopic seat 156 can compress the second elastic element, causing the second insert rod 157 to move into the telescopic countersunk hole, which in turn causes the first pulley 151 to move backward briefly. This effectively absorbs and disperses the impact energy from the elevator guide rail, preventing the impact from directly acting on the main structure of the measuring carriage 100 and preventing the measuring carriage 100 from shaking, displacing, or even being damaged due to excessive impact force. At the same time, the principle of the second stabilizing frame 160 structure, composed of the third insert rod 162, the third telescopic seat 163, and the third elastic element, is similar to that of the second insert rod 157, the second telescopic seat 156, and the second elastic element. The third telescopic seat 163 can compress the third elastic element, causing the third insert rod 162 to move upward through the mounting through hole, which in turn causes the second pulley 161 to move backward briefly. This effectively absorbs and disperses the impact energy from the bottom of the rail, allowing the measuring equipment to work in a relatively stable environment, which helps to improve the reliability and accuracy of the measurement data.

[0086] It is understandable that the anti-sway stabilizing mechanism 140 can also adjust the pulley height using a pneumatic spring. Upon impact, the pneumatic spring compresses, compressing the internal gas and increasing its pressure. According to the gas law, this pressure change absorbs and buffers the impact energy. Preferably, buffer pads can be installed at both ends of the pneumatic spring to further disperse the impact force. Alternatively, the anti-sway stabilizing mechanism 140 can use a hydraulic lifting column instead of the first telescopic seat 152 to adjust the pulley height, with a hydraulic damper installed at the connection between the hydraulic lifting column and the pulley. Upon impact, the piston inside the hydraulic damper moves in the liquid medium, and the liquid generates resistance through the damping orifice, thereby absorbing and dissipating the impact energy. This buffering method can automatically adjust the damping force according to the magnitude of the impact, achieving a highly efficient buffering effect.

[0087] In one embodiment, please refer to Figure 4 The mounting base 110 has a drive adjustment groove 171 and a limiting cylinder 172. The limiting cylinder 172 is located in the drive adjustment groove 171 and is slidably connected to the drive adjustment groove 171.

[0088] The first drive mechanism 300 includes a fourth insertion rod 301, a fourth telescopic seat 302, a fourth elastic component 303, a drive motor 304, a drive wheel 305, and an insertion rod drive mechanism. One end of the fourth insertion rod 301 is inserted into the limiting cylinder 172 and extends upward through the limiting cylinder 172 to be screwed to the second nut. The end of the fourth insertion rod 301 away from the mounting base 110 is provided with the fourth telescopic seat 302. The fourth telescopic seat 302 is connected to the limiting cylinder 172 through the fourth elastic component 303. The fourth telescopic seat 302 is provided with the drive motor 304, and the drive wheel 305 is mounted on the drive motor 304. The insertion rod drive mechanism (not shown in the figure) can drive the fourth insertion rod 301 to make the drive wheel 305 abut against the elevator guide rail. Preferably, the drive wheel 305 can be a rubber drive wheel 305 or a gear with a rubber sleeve, or it can be a textured or patterned plastic drive wheel 305.

[0089] Specifically, the sliding of the limiting cylinder 172 within the drive adjustment groove 171 allows the first drive mechanism 300 to adjust its relative position within a certain range. Simultaneously, the fourth telescopic seat 302 can be adjusted vertically via the second nut and the fourth elastic element, thereby better adapting to elevator guide rails of different specifications and installation conditions. This helps ensure that the drive wheel 305 accurately contacts the elevator guide rail, guaranteeing the effectiveness and stability of the drive regardless of changes in the specific size and position of the guide rail, thus improving the device's compatibility with different elevator systems. The rod drive mechanism ensures that the drive wheel 305 remains in contact with the elevator guide rail during testing to smoothly drive the measuring cart 100. Furthermore, when not in use, such as when idle, it can be placed on top of the elevator car, keeping the drive wheel 305 away from the elevator guide rail, thereby reducing friction between the drive wheel 305 and the elevator guide rail and extending the service life of the drive wheel 305.

[0090] It is understandable that the first drive mechanism 300 can also be an electromagnetic adsorption drive mechanism, including an electromagnetic chuck, a linear motor, an elastic buffer pad, and a drive controller 600. The electromagnetic chuck is mounted on a retractable bracket, which is connected to the mounting base 110 via a linear motor. An elastic buffer pad is placed between the electromagnetic chuck and the mounting base 110. When the measuring carriage 100 needs to be driven, the drive controller 600 controls the linear motor to push the electromagnetic chuck closer to the elevator guide rail. When the electromagnetic chuck approaches the surface of the guide rail, the controller 600 activates the electromagnetic chuck, causing it to generate a strong electromagnetic attraction and adhere to the guide rail. The elastic buffer pad acts as a buffer. Small electromagnetic drive units are set at the edge or inside of the electromagnetic chuck. These units alternately change the direction of the magnetic poles, allowing the electromagnetic chuck to crawl along the surface of the guide rail, thereby driving the measuring carriage 100 to move.

[0091] In one embodiment, such as Figure 2 As shown, the elevator guide rail inspection and management device also includes a dustproof protective cover 440 and a dustproof protective plate 450; wherein, a slide rail 460 is provided on the mounting base 110, the dustproof protective plate 450 is located at one end of the slide rail 460, and the dustproof protective cover 440 is slidably connected to the slide rail 460. When inspection work is performed, the dustproof protective cover 440 and the dustproof protective plate 450 abut against each other so that the laser plumb line 410 and the PSD position detector 420 are located inside the dustproof protective cover 440.

[0092] Specifically, during testing, the dust cover 440 slides along the slide rail 460 on the mounting base 110 until it comes into contact with the dust cover plate 450, thus forming a relatively enclosed space that encloses the laser plumb line 410 and the PSD position detector 420. This prevents most dust from adhering to the laser emitter and the receiving surface of the PSD position detector, thus preventing problems such as blurred laser spot imaging, signal attenuation, or increased detection errors caused by dust obstruction or laser scattering. This ensures clear and reliable detection data is obtained, thereby improving the accuracy and reliability of elevator guide rail verticality detection.

[0093] Please see Figure 6 This invention illustrates an elevator guide rail detection and management device provided in Embodiment 2 of the present invention. Compared with the elevator guide rail detection and management device described in Embodiment 1 above, the elevator guide rail detection and management device provided in this embodiment further includes a protective mechanism 700. The protective mechanism 700 includes a protective platform 710, a first drive arm 720, a second drive arm 730, a turning platform 740, and a tightening mechanism 750.

[0094] The protective platform 710 is mounted on the mounting base 110. One end of the first drive arm 720 is connected to the protective platform 710, and a third drive mechanism 721 for driving the first drive arm 720 to rotate is provided at the connection. The other end of the first drive arm 720 is connected to one end of the second drive arm 730, and a fourth drive mechanism 731 for driving the second drive arm 730 to rotate is provided at the connection. The other end of the second drive arm 730 is connected to the steering platform 740, and a fifth drive mechanism 741 for driving the steering platform 740 to rotate is provided at the connection.

[0095] The tightening mechanism 750 is installed on the turntable 740. The tightening mechanism 750 is used to pre-tighten the connecting parts of the elevator guide rail. The turntable 740 is equipped with a camera mechanism 742 and a marking mechanism 743. The marking mechanism 743 is equipped with a marking control valve 744.

[0096] The third drive mechanism 721, the fourth drive mechanism 731, the fifth drive mechanism 741, the tightening mechanism 750, and the marking control valve 744 are all electrically connected to the controller 600 and the power supply device 500. The camera mechanism 742 is electrically connected to the controller 600 to send the captured image information of the elevator guide rail connection to the power and control device.

[0097] Specifically, the control console uses camera mechanism 742 to monitor the connection status of the elevator guide rail joints in real time. If loosening is detected, such as loose bolts, the control console activates the third drive mechanism 721 on the protective platform 710 to rotate the first drive arm 720, the fourth drive mechanism 731 to rotate the second drive arm 730, and the fifth drive mechanism 741 to rotate the turning platform 740. Through the coordinated operation of these three drive mechanisms, the tightening mechanism 750 installed on the turning platform 740 is precisely positioned at the elevator guide rail connector, pre-tightening the connector to ensure the elevator guide rails do not detach from the elevator shaft in a short time. Simultaneously, camera mechanism 742 captures images of the guide rail connection and transmits them to the controller 600. Maintenance personnel can view these images to promptly identify installation defects, wear, or other abnormalities in the guide rail connectors, facilitating targeted maintenance and repair decisions and preventing the accumulation and escalation of potential safety hazards. The controller 600 can also control the marking control valve 744 on the marking mechanism 743, so that the marking mechanism 743 can mark the problem area so that subsequent maintenance personnel can quickly find the fault and carry out repairs.

[0098] See Figure 7 and Figure 8 The laser plumb line 410 includes an outer spherical shell 411, an inner sphere 412, a vertical stabilizing block 413, and a laser emitter 414.

[0099] The outer spherical shell 411 is mounted on the vertical mounting bracket 120. The outer spherical shell 411 and the inner sphere 412 are slidably connected by multiple balls 415, allowing the inner sphere 412 to roll freely within the outer spherical shell 411. When the device is slightly tilted, the inner sphere 412 automatically adjusts its balance under the influence of gravity. The outer spherical shell 411 has openings at both the top and bottom. A vertical stabilizing block 413 is connected to the inner sphere 412 through the lower opening of the outer spherical shell 411. The laser emitter 414 is embedded in the vertical stabilizing block 413, which is used to ensure that the laser emitted by the laser emitter 414 is always vertically downward.

[0100] The inner sphere 412 and the vertical stabilizing block 413 are provided with connecting pipes 417 through which the laser connecting pipe 416 of the laser emitter 414 passes. The inner sphere 412 is provided with a pipe guide platform 418 to ensure that the laser can still be emitted vertically downward smoothly after the guide rail deviates and causes the inner sphere 412 to move.

[0101] In one embodiment, such as Figure 1As shown, the elevator guide rail detection and management device also includes a distance detection mechanism 800, which includes a laser rangefinder 810 and a laser reflector 820. The laser rangefinder 810 and the laser reflector 820 are respectively mounted on two mounting bases 110 connected to the pressure boosting and stabilizing mechanism 200, and the laser rangefinder 810 points towards the laser reflector 820. The distance detection mechanism 800 is electrically connected to the controller 600 and the power supply device 500.

[0102] During long-term elevator operation, the guide rail spacing may change due to various reasons, such as building structure deformation and aging and wear of the guide rails themselves. A laser rangefinder 810 emits a laser beam, which is directed towards a laser reflector 820 mounted on the opposite mounting base 110. The laser reflector 820 reflects the laser beam back to the laser rangefinder 810. By measuring the time it takes for the laser to travel from emission to reflection, and utilizing the principle of the constant speed of light, the laser rangefinder 810 can accurately calculate the distance between itself and the laser reflector 820, which is the distance between the corresponding mounting bases 110 on the two elevator guide rails. This allows for the detection of the spacing between the elevator guide rails. This spacing data can be fed back to the controller 600 for comparison and analysis with preset standard spacing values. If the spacing exceeds the allowable error range, the controller 600 can promptly issue an alarm signal, prompting maintenance personnel to inspect and repair the elevator. This prevents elevator malfunctions caused by abnormal guide rail spacing, ensures the safe and stable operation of the elevator, and improves the reliability and safety management level of the entire elevator system.

[0103] Please see Figure 9 This invention illustrates an elevator guide rail detection and management method, which includes the following steps:

[0104] S910. Install the elevator guide rail detection and management device on the elevator guide rail to be tested, and start the pressurization and stabilization mechanism 200 to press the two measuring carts 100 onto the two elevator guide rails respectively.

[0105] S920: Activate the laser plumb line 410 to obtain the first laser image on the PSD position detector 420; activate the laser rangefinder 810 to obtain the second laser image of the track spacing of the elevator guide rail obtained by the laser reflector 820 on the laser rangefinder 810.

[0106] S930: By controlling the first drive mechanism 300 on the two measuring vehicles 100 to drive the measuring vehicle 100 to move up or down synchronously, the first laser image and the second laser image captured by the PSD position detector 420 and the laser rangefinder 810 during the measurement process are recorded.

[0107] S940. Process the first laser image and the second laser image to obtain and save the elevator guide rail verticality deviation curve and distance change deviation curve.

[0108] S950: Acquire an image of the elevator guide rail connection point captured by camera 742 and pre-tighten the loose connecting parts on the elevator guide rail by controlling the tightening structure on the protective device.

[0109] S960. After the pre-tightening process is completed, the pre-processed position is traced and marked by the marking control valve 744 on the control marking mechanism 743.

[0110] In summary, the elevator guide rail inspection and management method provided by this invention can comprehensively, efficiently, and accurately inspect and maintain elevator guide rails. Throughout the inspection process, the pressure-stabilizing mechanism 200 ensures the stable attachment of the measuring carriage 100 to the guide rail, effectively eliminating shaking interference and laying the foundation for subsequent accurate measurements. The coordinated operation of the laser plumb line 410, the PSD position detector, and the laser rangefinder 810 not only acquires the verticality data of the elevator guide rail in real time but also accurately monitors changes in the guide rail spacing. The generated verticality deviation curve and distance change deviation curve intuitively reflect the changes in the guide rail's condition, providing crucial evidence for assessing elevator operational safety. The image acquisition function of the camera mechanism 742 allows staff to remotely monitor the condition of the guide rail connections, promptly identify loose or damaged connectors, and then quickly perform pre-tightening using the tightening structure of the protective device, effectively preventing safety accidents caused by loose connectors. The tracer marking of the marking mechanism 743 greatly facilitates subsequent maintenance personnel in quickly locating and specifically repairing the pre-treated areas. This method enables integrated operation from detection to maintenance, significantly improving the automation and intelligence level of elevator guide rail detection, reducing errors and uncertainties that may be caused by manual intervention, effectively ensuring the safe and stable operation of elevators, reducing the risk of elevator failure, and extending the service life of elevators.

[0111] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
