Description

Technical Field

[0001] The present invention relates to the field of elevator detection, and in particular to an elevator guide rail detection management device and method. Background Art

[0002] With the advancement of industrial technology, elevators have become indispensable equipment in many offices, entertainment venues, and residential places. The elevator has two relatively vertical elevator rails and an elevator car installed between the two elevator rails; the verticality, parallelism and other dimensional parameters of the elevator rails will not only affect the comfort and life of the elevator, but also bring certain safety hazards. Therefore, the inspection and management of the elevator rails is particularly important.

[0003] The prior art CN118323986B provides an elevator guide rail inspection instrument, including a guide rail climbing robot and a detection device. The guide rail climbing robot is installed on both elevator guide rails. The guide rail climbing 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 up and down along the guide rails. A laser rangefinder is installed on one of the upper inner car bodies, and a laser reflection surface is installed on the other upper inner car body. Two-dimensional PSD position detectors are installed on both lower inner car bodies. Both upper inner car bodies are arranged with plumb gauge mounting frames, and plumb gauges are installed on the plumb gauge mounting frames. When the elevator car stops after running to a certain height, the lower inner car body is driven by the suspension rope lifting device to move up and down along the elevator guide rail. During the operation of the lower inner car body, the verticality deviation of the elevator guide rail can be immediately detected by the two-dimensional PSD position detector by feeding back the offset of the laser spot on it.

[0004] However, the device relies on the movement of the elevator car to drive the guide rail climbing robot. The elevator car will inevitably vibrate and shake during operation, which will be transmitted to the robot. After the car stops, the laser plumb line will still shake 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 continuity in the data, which affects the assessment of the true state of the track. Summary of the invention

DETAILED DESCRIPTION

[0058] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the invention more thorough and comprehensive.

[0059] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. The terms "parallel", "first", "second", "third" and similar expressions used herein are for illustrative purposes only.

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

[0061] The measuring vehicle 100 is used to be installed on the elevator guide rail. Two measuring vehicles 100 are in contact with two single-side guide rails of the elevator guide rail in a one-to-one correspondence. Each measuring vehicle 100 has a mounting seat 110, and the mounting seat 110 is provided with a plumb line mounting frame 120;

[0062] The two ends of the boosting and stabilizing mechanism 200 are respectively connected to two mounting seats 110 provided on different measuring vehicles 100 in a one-to-one correspondence; the boosting and stabilizing mechanism 200 is used to drive the two measuring vehicles 100 to have a movement tendency away from each other, so that the two measuring vehicles 100 are respectively pressed on the elevator guide rails.

[0063] Specifically, the detection work of the measuring vehicle 100 in the elevator shaft is affected by external factors (such as air flow fluctuations and slight vibrations in the elevator shaft) and the deviation of the elevator guide rails during movement. During the detection process, it may send shaking or displacement, and there is a risk of derailment and falling. On the one hand, the boosting and stabilizing mechanism 200 can make the two measuring vehicles 100 closely contact the elevator guide rails and apply pressure to them to resist the influence of external interference forces, so that the measuring vehicle 100 can maintain the stability of its own structure in a complex shaft environment and ensure 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 a smaller size of guide rails, the boosting effect of the boosting and stabilizing mechanism 200 can enable the measuring vehicle 100 to better fit the surface of the guide rail. If the guide rail size is large, by appropriately adjusting the pressure of the boosting and stabilizing mechanism 200, it can still ensure that the measuring vehicle 100 is in close contact with the guide rail, thereby improving the compatibility of the entire elevator guide rail detection and management device with elevator guide rails of different specifications.

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

[0065] On the one hand, the measuring vehicle 100 can realize self-driving detection work by means of the first driving mechanism 300, without driving along with the elevator car, thereby avoiding the influence of the shaking of the elevator car on the detection accuracy of the measuring vehicle 100; on the other hand, the self-driving mode realized by the first driving mechanism 300 provides the measuring vehicle 100 with the possibility of adapting to various detection environments and improving the detection safety, and the self-driving measuring vehicle 100 can freely and accurately reach the predetermined measurement position. For example, during the non-operating period of the elevator, the elevator detection work before the installation of the elevator car, or the specific maintenance detection window, the measuring path and key areas can be selected independently, which greatly improves the efficiency and pertinence of the measurement work; and in case of emergency, the braking or adjustment of the running direction can be quickly made to reduce the risk of accidents. However, the existing measuring vehicle 100 driven by the elevator car is limited by various factors of the elevator car (such as the operating parameters of the car itself, the shaking during the movement process, etc.), so it is impossible to adapt to different working environments and avoid dangerous accidents.

[0066] The two vertical detection mechanisms 400 are respectively located on two mounting seats 110 belonging to different measuring vehicles 100. 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 installed on the plumb line mounting frame 120. A second driving 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 provided on the second driving mechanism 430. The laser plumb line 410 points to the PSD position detector 420. The second driving mechanism 430 can drive the PSD position detector 420 to approach or move away from the laser plumb line 410.

[0067] Specifically, the PSD position detector 420 determines the coordinates of the light spot based on the photoelectric effect, and cooperates with the laser plumb line 410 to detect the verticality of the elevator guide rail. In actual operation, the brightness in the elevator shaft is complex and changeable. When it is too bright, it is interfered by the background light, and when it is too dark, it is affected by the signal noise, which will make the coordinates of the light spot unclear. The second driving mechanism 430 accurately drives the PSD position detector 420 to approach or move away from the laser plumb line 410. On the one hand, the accuracy of imaging can be guaranteed. 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 reduced to enhance the signal, thereby ensuring the accuracy of detection. 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 it is at different height sections of the guide rail or when dealing with changes in brightness, dust, etc. in the hoistway, it can be driven flexibly, so that the measuring vehicle 100 can continuously and stably obtain the verticality data of the elevator guide rail during movement, thereby realizing dynamic measurement of the elevator guide rail, providing a reliable basis for comprehensive evaluation of the guide rail condition, and ensuring safe operation of the elevator.

[0068] The power supply device 500 can be a town power supply, a rechargeable battery or a disposable battery, preferably a mobile power supply. The boost stabilization 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 may be a single chip microcomputer or the like, and the boost stabilization mechanism 200 , the first driving mechanism 300 and the vertical detection mechanism 400 are all electrically connected to the controller 600 .

[0070] The steps for using the elevator guide rail detection management device provided in the first embodiment of the present invention are as follows:

[0071] First, two measuring vehicles 100 are placed on two elevator guide rails to be inspected, and the boosting and stabilizing mechanism 200 is controlled by the controller 600 to make the measuring vehicle 100 fit closely with the guide rails, and apply pressure to make it firmly attached to the surface of the elevator guide rails. Next, the laser plumb line 410 is started, and the operation of the second driving mechanism 430 is controlled according to the imaging status of the PSD position detector 420. By changing the distance between the laser plumb line 410 and the PSD position detector 420, a clear laser imaging is obtained. Subsequently, the controller 600 is used to control the first driving mechanism 300 to synchronously drive the two measuring vehicles 100 to move along the extension direction of the elevator guide rails, so as to realize the detection of the verticality of the elevator guide rails. During the movement of the measuring vehicle 100, the controller 600 controls the second driving mechanism 430 in real time, dynamically changes the distance between the laser plumb line 410 and the PSD position detector 420, so as to ensure that clear imaging can be obtained during the entire detection process.

[0072] The beneficial effects of the elevator guide rail detection management device provided by the first embodiment of the present invention are:

[0073] The elevator guide rail detection and management device provided by the present invention replaces the traditional elevator car drive with a self-driving mode by designing a measuring vehicle 100 equipped with a first driving mechanism 300. In daily operation, the elevator car will inevitably shake due to factors such as carrying people and goods, starting and stopping, etc. This shaking will be directly transmitted to the measuring equipment, resulting in a significant deviation in the measurement accuracy. In addition, the self-driving measuring vehicle 100 has higher accuracy and can adjust the position required for measurement at will. Combined with the second driving mechanism 430 to correct the position of the PSD position detector 420 in real time during the movement, the entire movement process can produce clear laser imaging, thereby realizing detection while the elevator guide rail is moving, so that the measuring vehicle 100 can continuously and stably obtain the elevator guide rail verticality data during the movement, thereby realizing dynamic measurement of the elevator guide rail, providing a reliable basis for comprehensive evaluation of the guide rail condition, and ensuring the safe operation of the elevator.

[0074] Preferably, see Figure 3 , the boost 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 in a one-to-one correspondence. 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 shell 231 and a coupling 232 arranged in the protective shell 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 can ensure that there is a certain angle deviation between the first push rod mechanism 210 and the second push rod mechanism 220 to adapt to the left and right deviation of the elevator guide rail in its extension direction, so that the first push rod mechanism 210 and the second push rod mechanism 220 can always apply downward pressure perpendicular to the guide rail to the measuring vehicle 100 on both sides, which can ensure the stable attachment of the measuring vehicle 100 on the guide rail, avoid the change of pressure direction due to the left and right deviation of the guide rail, thereby reducing the abnormal friction between the measuring vehicle 100 and the guide rail caused by the lateral pressure, protecting the components of the measuring vehicle 100 and the guide rail surface, extending its service life and ensuring the accuracy of the measurement. At the same time, the use of the first push rod mechanism 210 and the second push rod mechanism 220 allows the boosting and stabilizing structure to flexibly adapt to elevator guide rails with different spacings. When facing guide rails with different specifications and spacings, the push rod mechanisms on both sides can change the length of the extended push rods, so that the measuring vehicle 100 can closely fit the guide rails to carry out detection work regardless of the guide rail spacing conditions, greatly improving the versatility and adaptability of the entire detection device.

[0077] It can be understood that the boost stabilization mechanism 200 can be a combination of two hydraulic telescopic cylinders and a universal joint. Through the adjustment of the hydraulic system, the telescopic length of the hydraulic telescopic cylinders on both sides can be easily changed to adapt to the elevator guide rails with different spacings, ensuring that the measuring vehicle 100 fits tightly. The universal joint is similar to the coupling 232 in the angle adjuster 230, which allows the hydraulic telescopic cylinder to rotate flexibly within a certain angle range. When the elevator guide rail deviates left and right in the extension direction, the universal joint can adjust the angle adaptively. The boost stabilization mechanism 200 can also be a combination of an electric lead screw and a ball joint structure. The electric lead screw is respectively installed on the mounting seat 110 of the corresponding measuring vehicle 100. Its high-precision lead screw transmission can accurately control the thrust size and telescopic 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, so that the measuring vehicle 100 can have good contact with the guide rail. The ball joint mechanism replaces the angle adjuster 230, which is connected between the two electric screws. The ball joint can rotate and swing at a certain angle in all directions. When the elevator guide rail deviates left or right, the ball joint can automatically adjust its posture so that the force applied by the electric screw is always perpendicular to the guide rail and downward.

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

[0079] The two first stabilizing frames 150 are arranged in sequence and at intervals along the axial direction of the positioning wheel 130, and are respectively arranged on the opposite sides of the positioning wheel 130. The first stabilizing frame 150 is equipped with a first pulley 151, and the first pulley 151 is used to abut the rail body of the elevator guide rail. The first stabilizing frame 150 is used to reduce the shaking phenomenon of the measuring vehicle 100 caused by the deviation of the elevator guide rail; the two second stabilizing frames 160 are arranged in sequence and at intervals along the axial direction of the positioning wheel 130, and are respectively arranged on the opposite sides of the positioning wheel 130. The second stabilizing frame 160 is equipped with a second pulley 161, and the second pulley 161 is used to abut the rail bottom of the elevator guide rail. The second stabilizing frame 160 is used to reduce the shaking phenomenon of the measuring vehicle 100 caused by the deviation of the elevator guide rail.

[0080] Specifically, when the elevator guide rail deviates in the horizontal direction, that is, when the rail body deviates, the interference force applied by the elevator guide rail to the measuring vehicle 100 will cause the measuring vehicle 100 to be affected in the horizontal direction and shake. The first pulley 151 cooperates with the first stabilizing frame 150, so that the first pulley 151 can evenly disperse the force when it is subjected to the interference force generated by the guide rail deviation, thereby effectively reducing the shaking transmitted to the measuring vehicle 100 due to the guide rail deviation, and ensuring the relative stability of the measuring vehicle 100 in the horizontal direction. Similarly, when the elevator guide rail deviates in the moving direction, that is, when the rail bottom deviates, the second pulley 161 cooperates with the second stabilizing frame 160, which can effectively reduce the shaking transmitted to the measuring vehicle 100 due to the guide rail deviation, and ensure the relative stability of the measuring vehicle 100 in the extension direction of the elevator guide rail.

[0081] Preferably, the first stabilizing frame 150 includes a first telescopic seat 152, a first insertion rod 153, a first elastic component 154, a first nut 155, a second telescopic seat 156 and a second elastic component 158; two second stabilizing frames 160 are respectively arranged on both sides of the positioning wheel 130 perpendicular to the moving direction, and the second stabilizing frame 160 includes a third insertion rod 162, a third telescopic seat 163 and a third elastic component 164;

[0082] The mounting seat 110 is provided with a plurality of mounting through holes, one end of the first plug rod 153 extends upward through one of the mounting through holes, passes through the mounting seat 110 and is screwed with the first nut 155, the other end of the first plug rod 153 is connected with the first telescopic seat 152, and the mounting seat 110 and the first telescopic seat 152 are connected through the first elastic component 154; the first telescopic seat 152 is provided with a telescopic countersunk hole on the side facing the elevator guide rail body, the telescopic countersunk hole is plugged with one end of the second plug rod 157, the other end of the second plug rod 157 is connected with the second telescopic seat 156, the first telescopic seat 152 and the second telescopic seat 156 are connected through the second elastic component 158, and the first pulley 151 is installed on the second telescopic seat 156;

[0083] One end of the third plug rod 162 is plugged into one of the mounting through holes, the other end of the third plug rod 162 is connected to the third telescopic seat 163, the mounting seat 110 is connected to the third telescopic seat 163 via the third elastic component 164, and the second pulley 161 is installed 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 the actual elevator guide rail detection scenario, different elevator guide rails may have certain height differences, or there may be local unevenness during the guide rail installation process. The pulley height is adjusted by the first telescopic seat 152. During the installation process, the distance between the first telescopic seat 152 and the mounting seat 110 can be changed by the first plug 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 plug rod 153 so that the first nut 155 is pressed on the mounting seat 110, thereby ensuring that the first pulley 151 of the measuring vehicle 100 can maintain a good contact state with the rail body of different guide rails of elevators, thereby adapting to different detection tasks;

[0085] Secondly, due to reasons such as aging or deformation of the elevator, the measuring vehicle 100 will be subjected to external force impact from the elevator guide rail body during operation. The second telescopic seat 156 can compress the second elastic element to make the second plug rod 157 move into the telescopic countersunk hole, so that the first pulley 151 moves back briefly, effectively absorbing and dispersing the impact energy from the elevator guide rail body, avoiding the impact directly acting on the main structure of the measuring vehicle 100, and preventing the measuring vehicle 100 from shaking, displacement or even damage due to excessive impact force; at the same time, the principle of the second stable frame 160 structure composed of the third plug rod 162, the third telescopic seat 163 and the third elastic element is also similar to the working distance of the second plug rod 157, the second telescopic seat 156 and the second elastic element. The third telescopic seat 163 can compress the third elastic element to make the third plug rod 162 move upward through the mounting through hole, so that the second pulley 161 moves back briefly, effectively absorbing and dispersing the impact energy from the rail bottom, so that the measuring equipment can work in a relatively stable environment, which helps to improve the reliability and accuracy of the measurement data.

[0086] It can be understood that the anti-sway stabilization mechanism 140 can also adjust the pulley height through a gas spring. When impacted, the gas spring will be compressed and deformed, the gas inside it will be compressed, and the pressure will increase. According to the gas state equation, the pressure change of the gas will absorb and buffer the impact energy. Preferably, buffer pads can be installed at both ends of the gas spring to further disperse the impact force; the anti-sway stabilization mechanism 140 can also use a hydraulic lifting column to replace the first telescopic seat 152 to adjust the pulley height, and a hydraulic damper is installed at the location where the hydraulic lifting column is connected to the pulley. When impacted, the piston inside the hydraulic damper moves in the liquid medium, and the liquid generates resistance through the damping hole, thereby absorbing and dissipating the impact energy. This buffering method can automatically adjust the damping force according to the size of the impact to achieve an efficient buffering effect.

[0087] In one embodiment, see Figure 4 The mounting seat 110 is provided with a driving adjustment groove 171 and a limiting cylinder 172 , and the limiting cylinder 172 is located in the driving adjustment groove 171 and is slidably connected with the driving adjustment groove 171 ;

[0088] The first driving mechanism 300 includes a fourth plug rod 301, a fourth telescopic seat 302, a fourth elastic component 303, a driving motor 304, a driving wheel 305 and a plug rod driving mechanism; one end of the fourth plug rod 301 is plugged into the limiting cylinder 172 and extends upward through the limiting cylinder 172 to be screwed with the second nut, the fourth plug rod 301 is provided with a fourth telescopic seat 302 at one end away from the mounting seat 110, 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 a driving motor 304, the driving wheel 305 is installed on the driving motor 304, and the plug rod driving mechanism (not shown) can drive the fourth plug rod 301 to make the driving wheel 305 abut against the elevator guide rail. Preferably, the driving wheel 305 can be a rubber driving wheel 305 or a gear with a rubber sleeve, or a plastic driving wheel 305 with a texture or pattern.

[0089] Specifically, the sliding of the limit cylinder 172 in the drive adjustment groove 171 enables the first drive mechanism 300 to adjust its relative position within a certain range. At the same time, the fourth telescopic seat 302 can be adjusted up and down through the second nut and the fourth elastic element to adjust its up and down position, so as to better adapt to elevator guide rails of different specifications and installation conditions, which helps to ensure that the drive wheel 305 can accurately contact the elevator guide rail. No matter how the specific size and position of the guide rail change, the effectiveness and stability of the drive can be guaranteed, thereby improving the compatibility of the device with different elevator systems. On the one hand, the plunger drive mechanism can make the drive wheel 305 always contact the elevator guide rail during the detection work to smoothly complete the drive of the measuring vehicle 100. On the other hand, it can be placed on the top of the elevator car when not measuring, such as when idle, so that the drive wheel 305 is away from the elevator guide rail, thereby reducing the friction between the drive wheel 305 and the elevator guide rail, and improving the service life of the drive wheel 305.

[0090] It can be understood that the first driving mechanism 300 can also be an electromagnetic adsorption driving mechanism, including an electromagnetic suction cup, a linear motor, an elastic buffer pad and a driving controller 600. The electromagnetic suction cup is installed on a retractable bracket, and the bracket is connected to the mounting seat 110 through a linear motor, and an elastic buffer pad is arranged between the electromagnetic suction cup and the mounting seat 110. When it is necessary to drive the measuring vehicle 100, the driving controller 600 controls the linear motor to push the electromagnetic suction cup closer to the elevator guide rail. When the electromagnetic suction cup approaches the surface of the guide rail, the controller 600 starts the electromagnetic suction cup to generate a strong electromagnetic suction force to adsorb on the guide rail. The elastic buffer pad plays a buffering role, and a small electromagnetic drive unit is arranged on the edge or inside of the electromagnetic suction cup. These units enable the electromagnetic suction cup to crawl along the surface of the guide rail by alternating the direction of the magnetic poles, thereby driving the measuring vehicle 100 to move.

[0091] In one embodiment, if Figure 2 As shown, the elevator guide rail detection 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 seat 110, and 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 performing detection work, the dustproof protective cover 440 abuts against the dustproof protective plate 450 so that the laser plumb line 410 and the PSD position detector 420 are located in the dustproof protective cover 440.

[0092] Specifically, when the detection work is carried out, the dust protection cover 440 slides along the slide rail 460 on the mounting seat 110 until it abuts against the dust protection plate 450, thereby forming a relatively closed space to cover the laser plumb line 410 and the PSD position detector 420. In this way, most of the dust will be blocked outside this protective space, avoiding dust from adhering to the laser emitting end and the receiving surface of the PSD position detector, preventing problems such as blurred spot imaging, signal attenuation or increased detection error caused by dust blocking and scattering the laser, ensuring that clear and reliable detection data can be obtained, thereby improving the accuracy and reliability of the elevator guide rail verticality detection.

[0093] See also Figure 6 , which shows an elevator guide rail detection and management device provided in the second embodiment of the present invention. Compared with the elevator guide rail detection and management device described in the first embodiment, the elevator guide rail detection and management device provided in this embodiment further includes a protection mechanism 700, and the protection mechanism 700 includes a protection platform 710, a first driving arm 720, a second driving arm 730, a turning platform 740 and a tightening mechanism 750;

[0094] The protection platform 710 is arranged on the mounting seat 110, one end of the first driving arm 720 is connected to the protection platform 710 and a third driving mechanism 721 is provided at the connection to drive the first driving arm 720 to rotate; the other end of the first driving arm 720 is connected to one end of the second driving arm 730 and a fourth driving mechanism 731 is provided at the connection to drive the second driving arm 730 to rotate; the other end of the second driving arm 730 is connected to the turning platform 740 and a fifth driving mechanism 741 is provided at the connection to drive the turning platform 740 to rotate;

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

[0096] The third driving mechanism 721, the fourth driving mechanism 731, the fifth driving 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, and the camera mechanism 742 is electrically connected to the controller 600 to send the image information of the elevator guide rail connection to the power and control device.

[0097] Specifically, the control console observes the connection status of the elevator guide rail connection in real time through the camera mechanism 742. When the guide rail connection is found to be loose, such as the bolt is loose, the control console controls the third driving mechanism 721 on the protection platform 710 to drive the first driving arm 720 to rotate, the fourth driving mechanism 731 to drive the second driving arm 730 to rotate, and the fifth driving mechanism 741 to drive the turning platform 740 to rotate. Through the coordination of these three driving mechanisms, the tightening mechanism 750 installed on the turning platform 740 is accurately positioned at the connecting part of the elevator guide rail, and the connecting part is pre-tightened to ensure that the elevator guide rail will not fall off from the elevator shaft in a short time. At the same time, the camera mechanism 742 captures the image information of the guide rail connection and transmits it to the controller 600. The maintenance personnel can view these images to timely discover the installation defects, wear or other abnormal conditions of the guide rail connection parts, so as to make targeted maintenance and repair decisions and avoid the accumulation and expansion 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 for subsequent maintenance personnel to quickly find the fault location and perform repairs.

[0098] See also 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 transmitter 414;

[0099] The outer spherical shell 411 is mounted on the plumb line mounting frame 120. The outer spherical shell 411 and the inner spherical body 412 are slidably connected by a plurality of balls 415, so that the inner spherical body 412 can roll freely in the outer spherical shell 411. When the device position is slightly tilted, the inner spherical body 412 automatically adjusts the balance under the action of gravity. The upper and lower ends of the outer spherical shell 411 are open. The vertical stabilizing block 413 is connected to the inner spherical body 412 through the lower end opening of the outer spherical shell 411. The laser emitter 414 is embedded in the vertical stabilizing block 413. The vertical stabilizing block 413 is used to drive the laser emitted by the laser emitter 414 to always point vertically downward.

[0100] A connecting pipe 417 is provided between the inner sphere 412 and the vertical stabilizing block 413 for the laser connecting pipe 416 of the laser emitter 414 to pass through. A pipe guide platform 418 is provided in the inner sphere 412 to ensure that the laser can still be smoothly emitted vertically downward when the guide rail deviates and causes the inner sphere 412 to move.

[0101] In one embodiment, if Figure 1As shown, the elevator guide rail detection 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 installed on two mounting seats 110 connected to the boost stabilization mechanism 200, and the laser rangefinder 810 points to the laser reflector 820; the distance detection mechanism 800 is electrically connected to the controller 600 and the power supply device 500 respectively.

[0102] During the long-term operation of the elevator, the guide rails may change the distance between the guide rails due to various reasons, such as deformation of the building structure, aging and wear of the guide rails themselves, etc. The laser rangefinder 810 emits a laser beam, which is directed to the laser reflector 820 installed on the opposite mounting seat 110, and the laser reflector 820 reflects the laser beam back to the laser rangefinder 810. By measuring the time from the laser emission to the reflection back, and using the principle of constant light speed, the laser rangefinder 810 can accurately calculate the distance between itself and the laser reflector 820, that is, the distance between the corresponding mounting seats 110 on the two elevator guide rails, thereby realizing the detection of the distance between the elevator guide rails. These distance data can be fed back to the controller 600 and compared and analyzed with the preset standard distance value. Once it is found that the distance exceeds the allowable error range, the controller 600 can promptly issue an alarm signal to prompt the maintenance personnel to check and repair, prevent the elevator operation failure caused by abnormal guide rail spacing, ensure the safe and stable operation of the elevator, and improve the reliability and safety management level of the entire elevator system.

[0103] See also Fig. 9 , which shows an elevator guide rail detection management method provided by the present invention, the method comprising the following steps:

[0104] S910, installing the elevator guide rail detection management device on the elevator guide rail to be detected, starting the booster stabilization mechanism 200 to press the two measuring vehicles 100 onto the two elevator guide rails respectively;

[0105] S920, start the laser plumb line 410, obtain the first laser imaging on the PSD position detector 420, start the laser rangefinder 810, and obtain the second laser imaging of the track spacing of the elevator guide rail obtained by the laser rangefinder 810 through the laser reflector 820;

[0106] S930, controlling the first driving mechanisms 300 on the two measuring vehicles 100 to synchronously drive the measuring vehicles 100 to move upward or downward, and simultaneously recording 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;

[0107] S940, processing the first laser image and the second laser image to obtain and save a verticality deviation curve and a distance change deviation curve of the elevator guide rail;

[0108] S950, obtaining the guide rail image of the elevator guide rail connection taken by the camera mechanism 742 and pre-tightening the loose connectors on the elevator guide rail by controlling the tightening structure on the protective device;

[0109] S960, after the pre-tightening process is completed, the position where the pre-processing is performed is traced and marked by controlling the marking control valve 744 on the marking mechanism 743.

[0110] In summary, the elevator guide rail detection management method provided by the present invention can comprehensively, efficiently and accurately detect and maintain the elevator guide rail. In the entire detection process, the boost stabilization mechanism 200 ensures that the measuring vehicle 100 is firmly attached to the guide rail, effectively eliminates shaking interference, and lays the foundation for subsequent accurate measurement. The coordinated operation of the laser plumb line 410, the PSD position detector and the laser rangefinder 810 can not only obtain the verticality data of the elevator guide rail in real time, but also accurately monitor the changes in the guide rail spacing. The generated verticality deviation curve and distance change deviation curve intuitively reflect the state changes of the guide rail, providing a key basis for evaluating the safety of elevator operation. The image acquisition function of the camera mechanism 742 enables the staff to remotely monitor the status of the guide rail connection, promptly discover loose or damaged connectors, and then quickly perform pre-tightening processing with the help of the tightening structure of the protective device, effectively preventing safety accidents caused by loose connectors. The tracer mark of the marking mechanism 743 greatly facilitates the rapid positioning and targeted repair of the pre-treatment position by subsequent maintenance personnel. This method realizes the integrated operation from detection to maintenance, significantly improves the automation and intelligence level of elevator guide rail detection, reduces the errors and uncertainties that may be caused by manual intervention, effectively ensures the safe and stable operation of elevators, reduces the risk of elevator failures, and extends the service life of elevators.

[0111] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
