[0023] Please see Figure 1 and Figure 2 This invention provides an elevator guide rail verticality detection and correction system, comprising: The detection device 10 includes an upper guide rail 11, a lower guide rail 12, multiple wires 13, and multiple voltage detection mechanisms 14. Guide wheel mechanisms 15 are provided on both sides of the upper guide rail 11 and the lower guide rail 12. The guide wheel mechanism 15 includes a drive assembly (not shown) and multiple movable guide wheels 151. The multiple movable guide wheels 151 of the same guide wheel mechanism 15 are arranged around a preset detection space 152. The drive assembly is driven to drive the movable guide wheels 151 to move closer to or away from the preset detection space 152. Multiple wires 13 are arranged between the upper guide rail 11 and the lower guide rail 12. The wires 13 pass around one of the movable guide wheels 151 of the guide wheel mechanism 15 of the lower guide rail 12 and one of the movable guide wheels 151 of the guide wheel mechanism 15 of the upper guide rail 11. Multiple wires 13 are arranged around each preset detection space 152. The voltage detection mechanism 14 is used to be installed on the elevator guide rail 30 and electrically connected to the wires 13. Two correction devices 20 are respectively arranged on both sides of the elevator shaft. Each correction device 20 includes multiple position adjustment mechanisms 21. The position adjustment mechanisms 21 are installed on the side of the elevator shaft. The position adjustment mechanisms 21 on the same side are arranged from top to bottom. The position adjustment mechanisms 21 are used to push the elevator guide rail 30 to adjust the position of the elevator guide rail 30. The voltage detection mechanism 14 is connected to the position adjustment mechanism 21 and the drive component via signal.

[0024] The working principle of an elevator guide rail verticality detection and correction system according to an embodiment of the present invention is explained below: The upper guide rail seat 11 is installed at the top of the elevator shaft, and the lower guide rail seat 12 is installed at the bottom of the elevator shaft, so that both the upper guide rail seat 11 and the lower guide rail seat 12 are located between the two elevator guide rails 30 in the elevator shaft. Part of the elevator guide rail 30 extends into the preset detection space 152, and at least part of the guide rail surface of the elevator guide rail 30 is located in the preset detection space 152. During installation, the positions of the upper guide rail seat 11 and the lower guide rail seat 12 need to be adjusted. Since the guide wire 13 is the reference for detecting the verticality of the elevator guide rail 30, it is necessary to ensure that the part of the guide wire 13 located between the lower guide rail seat 12 and the upper guide rail seat 11 meets the verticality requirements.

[0025] During testing, the drive components on the upper guide rail seat 11 and the lower guide rail seat 12 synchronously drive the movable guide wheel 151 to move toward the preset testing space 152, so that the part of the wire 13 located between the lower guide rail seat 12 and the upper guide rail seat 11 approaches the guide rail surface of the elevator guide rail 30 in the preset testing space 152, until the wire 13 reaches the stopping position or until the voltage drop detection mechanism detects an abnormal voltage.

[0026] If the conductor 13 does not contact the surface of the elevator guide rail 30 during its journey to the stopping position, it indicates that the verticality of the elevator guide rail 30 meets the requirements. The specific stopping position of the conductor 13 is determined according to the verticality requirements of the elevator guide rail 30. When the conductor 13 is in the stopping position, a certain distance is maintained between the conductor 13 and the surface of the elevator guide rail 30, that is, the conductor 13 does not contact the elevator guide rail 30.

[0027] During the process of the conductor 13 reaching the stopping position, if the conductor 13 comes into contact with the surface of the elevator guide rail 30, since the surface of the elevator guide rail 30 is usually coated with an insulating layer (such as anti-rust oil), when the conductor 13 comes into contact with the surface of the elevator guide rail 30, it is equivalent to the conductor 13 being connected in parallel with a resistor with a large resistance value. The voltage detection mechanism 14, which is electrically connected to the conductor 13, will detect the change in voltage of the conductor 13. Therefore, the verticality of the elevator guide rail 30 can be judged by detecting the change in voltage of the conductor 13 by the voltage detection mechanism 14. After the voltage detection mechanism 14 detects the change in voltage of the conductor 13, the voltage detection mechanism 14 sends a signal, and the position adjustment mechanism 21 pushes the elevator guide rail 30 to move, thereby adjusting the position of the elevator guide rail 30. The drive component receives the signal and stops moving and drives the movable guide wheel 151 away from the preset detection space 152.

[0028] The preset distance by which the position adjustment mechanism 21 moves the elevator guide rail 30 is designed according to actual needs. To improve adjustment accuracy, the preset distance is designed to be relatively small, allowing the position adjustment mechanism 21 to make only minor adjustments to the elevator guide rail 30 before performing the next test. If the verticality of the elevator guide rail 30 is still unqualified, the position adjustment mechanism 21 will adjust it again, repeating this process multiple times until the verticality of the elevator guide rail 30 is qualified. This multiple fine-tuning method improves the accuracy of adjusting the elevator guide rail 30.

[0029] Because the guide rail surface is machined to a high degree of perpendicularity, if the perpendicularity of the elevator guide rail 30 is not up to standard, the first point where the elevator guide rail 30 comes into contact with the wire 13 during the testing process should be the guide rail joint. The voltage detection mechanism 14 can be arranged at the guide rail joint to facilitate the detection of voltage changes. The number of voltage detection mechanisms 14 is adjusted according to the number of guide rail joints of the elevator guide rail 30.

[0030] Multiple wires 13 can simultaneously detect the perpendicularity of multiple guide rail surfaces of the elevator guide rail 30, which helps to speed up the detection efficiency.

[0031] In some optional embodiments, the detection device 10 further includes a wire tensioning device, which is disposed on the lower guide rail seat 12. One end of the wire 13 is connected to the wire tensioning device, and the other end of the wire 13 sequentially passes around one of the movable guide wheels 151 of one of the guide wheel mechanisms 15 of the lower guide rail seat 12, one of the movable guide wheels 151 of one of the guide wheel mechanisms 15 of the upper guide rail seat 11, one of the movable guide wheels 151 of another guide wheel mechanism 15 of the upper guide rail seat 11, and one of the movable guide wheels 151 of another guide wheel mechanism 15 of the lower guide rail seat 12, and then connects to the wire tensioning device. When the movable guide wheel 151 moves, the wire tensioning device can tighten both ends of the wire 13, thereby keeping the wire 13 taut and preventing the wire 13 from slack and affecting the detection of verticality. Moreover, this design can reduce the number of wires 13.

[0032] The specific structure of the wire tensioning device can be designed according to actual needs. For example, the wire tensioning device includes a housing and multiple electric winding machines installed inside the housing. One end of the wire 13 is fixed to the housing, while the other end of the wire 13 passes around the corresponding movable guide wheels 151 and is then wound onto the electric winding machines. The electric winding machines straighten the wire 13 by winding it up, and can also prevent the wire 13 from loosening. Alternatively, the wire tensioning device may include multiple fixing parts and multiple translation drive components. One end of the wire 13 is connected to the fixing part, and the other end of the wire 13 passes around the corresponding movable guide wheels 151 and is then connected to the translation drive components. The translation drive components move the other end of the wire 13 to achieve tensioning. The translation drive components can be lead screw assemblies, electric cylinders, pneumatic cylinders, hydraulic cylinders, etc.

[0033] To facilitate the extension of each wire 13 to different sides of the preset detection space 152 and to keep the wires 13 stable, in some optional embodiments, the guide wheel mechanism 15 includes several fixed guide wheels 153. The fixed guide wheels 153 are arranged on the side of the movable guide wheel 151 away from the preset detection space 152. The wires 13 sequentially pass around the fixed guide wheels 153 and the movable guide wheels 151, and then extend to the preset detection space 152. In this embodiment, the guide wheel mechanism 15 includes two fixed guide wheels 153 and three movable guide wheels 151. Wires 13 need to be arranged on three sides of the preset detection space 152. There are three wires 13: one goes around to the front of the two preset detection spaces 152, another goes around to the side of the two preset detection spaces 152 facing each other, and the last goes around to the rear of the two preset detection spaces 152. Since the wire tensioning device is located between the two preset detection spaces 152, in order to facilitate the extension of the wires 13 in a vertical direction toward the front or rear of the preset detection space 152, the extension of the wires 13 can be changed by the fixed guide wheels 153. In the extension direction, two fixed guide wheels 153 are distributed on the front and rear sides of the preset detection space 152, and the movable guide wheel 151 is located between the fixed guide wheel 153 and the preset detection space 152. The wire 13 passes through the fixed guide wheel 153 and then extends towards the front or rear side of the preset detection space 152. The groove of the wire 13 of the movable guide wheel 151 located on the front or rear side of the preset detection space 152 also extends towards the front or rear side of the preset detection space 152. Therefore, by adjusting the direction of the wire 13 through the fixed guide wheel 153, the wire 13 is not easy to come loose from the groove of the wire 13 of the movable guide wheel 151 when the movable guide wheel 151 moves.

[0034] In some optional embodiments, clearance notches 111 are provided on both sides of the upper guide rail seat 11 and both sides of the lower guide rail seat 12. A portion of the preset detection space 152 is located in the clearance notch 111. When installing the upper guide rail seat 11 and the lower guide rail seat 12, the elevator guide rail 30 extends into the clearance notch 111. By comparing the distance between the side wall of the clearance notch 111 and the guide rail surface of the elevator guide rail 30, the clearance notches 111 of the upper guide rail seat 11 and the clearance notches 111 of the lower guide rail seat 12 overlap in the vertical projection direction, thereby aligning the upper guide rail seat 11 and the lower guide rail seat 12. Moreover, the clearance notch 111 also facilitates determining whether the relative positions of the upper guide rail seat 11 and the lower guide rail seat 12 meet the installation requirements.

[0035] The spacing between the elevator guide rails 30 on both sides of different elevator shafts may vary. To improve adaptability, in some optional embodiments, both the upper guide rail seat 11 and the lower guide rail seat 12 include a distance adjustment component and two bases 112. The two bases 112 are movably connected by the adjustment component, allowing them to move closer or further apart. A guide wheel mechanism 15 is provided on each base 112. When installing the upper and lower guide rail seats 11 and 12, the position of the bases 112 can be adaptively adjusted using the distance adjustment component, thereby allowing the two bases 112 to adjust their positions according to the spacing of the elevator guide rails 30. The distance adjustment component can be a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc. For example, the distance adjustment component can be a screw, which is rotatably mounted on one base 112 and threadedly engaged with the other base 112. Rotating the screw drives the two bases 112 to move closer or further apart.

[0036] The specific structure of the voltage detection mechanism 14 can be designed according to actual needs. For example, in some optional embodiments, the voltage detection mechanism 14 includes a voltage sensor 141 and a plurality of contact pins 142. The voltage sensor 141 is disposed on the elevator guide rail 30. The contact pins 142 are electrically connected to the voltage sensor 141 and abut against the wire 13. The contact pins 142 extend along the moving direction of the movable guide wheel 151. When the movable guide wheel 151 moves, the wire 13 can maintain contact with the contact pins 142, so that the wire 13 can maintain electrical connection with the contact pins 142.

[0037] The voltage detection mechanism 14, the guide wheel mechanism 15, and the position adjustment mechanism 21 can all include wireless communication modules, thereby facilitating the establishment of wireless communication between them and enabling signal transmission. In this embodiment, the wireless communication module establishes wireless communication with the user's control terminal. The voltage detection mechanism 14, the guide wheel mechanism 15, and the position adjustment mechanism 21 all achieve wireless communication with each other through the control terminal. After detecting a voltage change, the voltage detection mechanism 14 transmits the signal to the control terminal through the wireless communication module. The control terminal then sends control commands to the wireless communication modules of the guide wheel mechanism 15 and the position adjustment mechanism 21, thereby causing the drive components of the guide wheel mechanism 15 and the position adjustment mechanism 21 to operate accordingly.

[0038] The wireless communication module can be a Bluetooth module, a Wi-Fi module, a 3G / 4G / 5G module, etc., and is not limited to this example.

[0039] It should be noted that, for easier illustration, only a portion of the voltage detection mechanisms 14 and a portion of the position adjustment mechanisms 21 are shown in the illustration.

[0040] Please see Figure 3 The specific structure of the position adjustment mechanism 21 can be designed according to actual needs. For example, in some optional embodiments, the position adjustment mechanism 21 includes a support frame 211, a movable frame 212, and two telescopic components 213. The support frame 211 is located on the side of the elevator shaft, the movable frame 212 is movably mounted on the support frame 211, and the telescopic components 213 are arranged side by side on the support frame 211 and are drivenly connected to the movable frame 212. The movable frame 212 moves closer to or further away from the support frame 211 under the drive of the telescopic components 213. The telescopic components 213 are signal-connected to the voltage detection mechanism 14. When both telescopic components 213 extend or retract simultaneously to adjust the position of the movable frame 212, the position of the elevator guide rail 30 can be adjusted reciprocally in one direction. When one telescopic component 213 remains stationary while the other telescopic component 213 extends or retracts to adjust the position and angle of the movable frame 212, the position and angle of the elevator guide rail 30 can be adjusted. Of course, adjusting the position and angle of the elevator guide rail 30 can also be achieved when one telescopic component 213 extends while the other telescopic component 213 retracts.

[0041] Of course, in order to better achieve position adjustment, position adjustment mechanisms 21 can also be arranged on multiple sides of the preset detection space 152, so as to facilitate position adjustment of the elevator guide rail 30 in more directions.

[0042] The specific structure of the telescopic component 213 can be designed according to actual needs. For example, the telescopic component 213 can be a lead screw drive component, a rotary motor translation drive component, a belt translation drive component, a cylinder translation drive component, or a linear motor translation drive component. In this embodiment, the telescopic component 213 adopts a linear motor translation drive component, which is mounted on the support frame 211 and drivenly connected to the movable frame 212.

[0043] The specific structure of the correction device 20 can be designed according to actual needs. For example, in some optional embodiments, the correction device 20 includes a limiting frame 22 and two position adjustment mechanisms 21. The limiting frame 22 is located between the two position adjustment mechanisms 21 and is used to limit and cooperate with the elevator guide rail 30. When one position adjustment mechanism 21 adjusts the position of the elevator guide rail 30 while the other position adjustment mechanism 21 does not adjust, the elevator guide rail 30 can be adjusted in angle with the limiting frame 22 as a fulcrum, thereby achieving adjustment in more directions and making it easier for the elevator guide rail 30 to better meet the verticality requirements of the elevator guide rail 30.

[0044] In some optional embodiments, the detection device 10 also includes a wire cleaning device, which is disposed on the upper guide rail seat 11 and the lower guide rail seat 12. A portion of the wire 13 moves through the wire cleaning device. The wire cleaning device can clean the surface of the wire 13. When the wire 13 comes into contact with the elevator guide rail 30, it may get rust-preventive oil and other impurities on the surface of the elevator guide rail 30. The wire cleaning device can clean the impurities on the surface of the wire 13, thereby avoiding affecting subsequent detection.

[0045] The specific structure of the wire cleaning device can be designed according to actual needs. For example, the wire cleaning device includes cleaning brushes, cleaning sponges, etc. When the wire 13 passes through the wire cleaning device, impurities on the surface of the wire 13 can be cleaned by the wire cleaning device.

[0046] In some alternative embodiments, the detection device 10 further includes a power supply assembly 18, which is disposed on the lower guide rail 12 and electrically connected to the drive assembly and the wire 13. The power supply assembly 18 supplies power to the drive assembly and the wire 13, thus eliminating the need to connect to the mains power and making power connection more convenient.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
