[0002] Elevator guide rails are a crucial component of the elevator's guide system. They guide the movement of the car and counterweight, while also limiting their free range of motion. Elevator guide rails are manufactured in strict accordance with relevant standards during production. During factory inspection, guide rail verticality is a key inspection indicator, directly impacting elevator safety and passenger comfort. Excessive guide rail verticality errors can cause major operational accidents, endangering life and property, and even personal safety. Therefore, guide rail verticality testing is a crucial task during elevator installation, operation, and maintenance.

[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Example:

[0037] See also Figure 1 and Figure 2 This embodiment discloses a fully automatic inspection and detection system for elevator tracks, including a car body 10, a laser transmitter 20, and a laser receiver 30. Two car bodies 10 are arranged on the elevator track 40, one car body 10 is installed with the laser transmitter 20, and the other car body 10 is installed with the laser receiver 30.

[0038] Specifically, the two car bodies 10 are placed on the same elevator track 40 and arranged one above the other, with a certain distance between the two car bodies 10.

[0039] The laser transmitter 20 is mounted on the upper vehicle body 10 , and the laser receiver 30 is mounted on the lower vehicle body 10 , and the laser emitted by the laser transmitter 20 faces the laser receiver 30 .

[0040] In this embodiment, the elevator track 40 is T-shaped and fixedly installed within the elevator hoistway, with its center extending toward the center of the elevator shaft. The car body 10 includes multiple wheels 11, which are made of magnets and are located on either side of the center of the elevator track 40. Because the wheels 11 are made of magnets, the attractive force between the wheels 11 and the elevator track 40 secures the car body 10 to the track 40. Furthermore, by placing the multiple wheels 11 in contact with either side of the center of the track 40, the track 40 is clamped, thereby stabilizing the car body 10.

[0041] Two car bodies 10 are arranged on the same elevator track 40, and a laser transmitter 20 and a laser receiver 30 are respectively arranged on the two car bodies 10. By controlling the movement of the two car bodies 10 on the elevator track 40, the verticality of each section on the elevator track 40 and the verticality of the entire elevator track 40 can be detected.

[0042] During operation, the positions of the two car bodies 10 can be controlled to collect data from any position within the measurement range. During testing, the two car bodies 10 move a certain distance and then stop. The laser transmitter 20 and laser receiver 30 detect the verticality of the section of elevator track 40 between the two car bodies 10. This technical solution can collect verticality data at any position of the elevator guide rail, providing reliable data support for subsequent verticality correction work.

[0043] In one specific embodiment:

[0044] The vehicle body 10 also includes a frame 12, a motor 13, a battery (not shown), and a remote control module (not shown). The detection system also includes a remote control (not shown). The wheels 11, motor 13, battery, and remote control module are all mounted on the frame 12.

[0045] The vehicle frame 12 is U-shaped, with its ends positioned on either side of the elevator track 40. Multiple wheels 11 are provided, located on either side of the elevator track 40, and are indirectly connected to the vehicle frame 12. The output shaft of the motor 13 is power-connected to the wheels 11 and is used to drive the wheels 11. A battery is electrically connected to the motor 13 and provides power to the motor 13. Furthermore, the remote control module is also powered by the battery and is electrically connected to the motor 13, allowing for direct control of the motor 13's start and stop, as well as its forward and reverse rotation.

[0046] The remote controller and the remote control module are connected by wireless communication, so that the start and stop of the motor 13 and the forward / reverse rotation of the motor 13 can be remotely controlled by the remote controller.

[0047] In this embodiment, a specific structure of the vehicle body 10 is provided, and a specific method for controlling the movement of the vehicle body 10 is provided.

[0048] In another specific embodiment:

[0049] The wheel 11 installation structure on both sides of the elevator track 40 is symmetrical. There are four wheels 11 on one side of the elevator track 40. The four wheels 11 are respectively connected to the power of two motors 13. Both ends of the motor 13 have output shafts. A wheel 11 is respectively provided at the two output shaft ends of the same motor 13. The two motors 13 are arranged one in front and one behind, and their output shafts are parallel to each other.

[0050] In this embodiment, the motor 13 can directly drive all the wheels 11 to move synchronously on the elevator track 40.

[0051] In another specific embodiment:

[0052] The width of the frame 12 is adjustable, so that the distance between the wheels 11 on both sides of the frame 12 is adjustable. Through the adjustable width of the frame 12, the detection system is applicable to elevator rails 40 of different specifications.

[0053] Specifically, the frame 121 includes a connecting plate 121, a support plate 122, a spring 123 and a connecting column 124. The connecting plate 121 is U-shaped, with both sides of the connecting plate 121 located on both sides of the elevator track 40. The two ends of the connecting plate 121 are respectively connected to a support plate 122 through a spring 123.

[0054] Furthermore, a plurality of connecting posts 124 are vertically arranged on the support plate 122 , a plurality of through holes are arranged at the end of the connecting plate 121 , and each connecting post 124 passes through a through hole. A spring 123 is sleeved on each connecting post 124 .

[0055] The battery and motor 13 are both mounted on the support plate 122 , wherein a motor 13 is provided at each end of the support plate 122 . The output shafts of the two motors 13 are arranged parallel to each other and are each provided with a wheel 11 .

[0056] Preferably, the support plate 122 includes a shell, the battery is located in the shell, the motor 13 is arranged at the end of the shell, and the connecting column 124 is provided on the shell.

[0057] In this embodiment, the two support plates 122 are connected between the two ends of the connecting plate 121 by the spring 123, and a structure in which the distance between the two support plates 122 is adjustable is realized, and the two support plates 122 can be pressed together.

[0058] In another specific embodiment:

[0059] The outside of the wheel 11 is wrapped with a layer of silicone, which increases the friction between the wheel 11 and the elevator rail 40, thereby preventing the frame 12 from sliding down.

[0060] In another specific embodiment:

[0061] A bracket 14 is located in the middle of the frame 12 and extends along the length of the top surface of the elevator rail 40. A positioning wheel 15, also made of magnets, is located at each end of the bracket 14. A laser receiver 30 or a laser transmitter 20 is mounted on the bracket 14.

[0062] In this embodiment, by providing a bracket 14, two positioning wheels 15 can be mounted on the vehicle frame, thereby defining the position of the laser receiver 30 or the laser transmitter 20. Furthermore, the positioning wheels 15 provide feedback on the travel distance of the vehicle body 10 based on their fixation. Furthermore, the positioning wheels 15 move along the top surface of the elevator track 40, assisting in positioning the vehicle body 10. Furthermore, the positioning wheels 15 are made of magnets, ensuring that they remain in constant contact with the top surface of the elevator track 40.

[0063] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
