Description

Technical Field

[0001] This utility model relates to the field of guide rail deformation detection technology, specifically, to an elevator guide rail deformation detection device. Background Technology

[0002] In the production process of elevator guide rails, quality control is a crucial link, as it directly relates to the overall safety and stability of the elevator system. Deformation detection after elevator guide rail production is a core part of quality control and an important step to ensure the safe operation of elevators; its importance is self-evident.

[0003] In existing testing methods, the straightness of T-shaped guide rails is generally tested using traditional manual handheld testing instruments. Although this method can make a preliminary judgment based on the operator's professional knowledge and experience, its limitations are obvious. This method is not only time-consuming and labor-intensive, but the accuracy of the test results also depends heavily on the operator's skills and condition, making it difficult to guarantee that each guide rail can be evaluated consistently and accurately. In addition, with the expansion of production scale and the increase in guide rail length, the efficiency of manual testing is greatly reduced, making it difficult to meet the needs of fast production lines. Utility Model Content

[0004] This invention proposes an elevator guide rail deformation detection device to solve the problems of time-consuming and labor-intensive manual handheld detection in the prior art, as well as low calibration efficiency.

[0005] The technical solution of this utility model is as follows: An elevator guide rail deformation detection device is applied to an elevator guide rail, including a base, a fixing plate, a placement seat, a fixing component, and a detection mechanism. The fixing plate is fixedly connected to the base, and the placement seat is fixedly connected to one end of the fixing plate. The placement seat has a receiving cavity for placing the elevator guide rail. The fixing component is disposed on the placement seat for pressing and fixing both ends of the elevator guide rail. The detection mechanism is movable above the placement seat through a moving mechanism for detecting whether the elevator guide rail has deformed.

[0006] Preferably, the fixing component includes a first electric cylinder and an abutment plate. The first electric cylinder is installed at both ends of the placement seat. The output end of the first electric cylinder passes through the side wall of the placement seat and extends into the receiving cavity. The output end of the first electric cylinder is fixedly connected to the abutment plate, and the abutment plate slides in cooperation with the inner wall of the receiving cavity.

[0007] Furthermore, the moving mechanism includes a support frame, a slider, and a second electric cylinder. One end of the support frame is fixedly connected to the top of the fixed plate. A T-shaped groove is provided on the support frame. One end of the slider is slidably engaged with the T-shaped groove. The second electric cylinder is mounted on the support frame. The output end of the second electric cylinder passes through the outer wall of the support frame and extends into the T-shaped groove. The output end of the second electric cylinder is fixedly connected to the slider.

[0008] Furthermore, the detection mechanism includes a fixed base, a mounting plate, a laser collimator, and a buzzer. One end of the fixed base is fixedly connected to the other end of the slider. A movable groove is provided inside the fixed base. The mounting plate is movably positioned above the placement seat via a drive assembly. The laser collimator is mounted on one end of the mounting plate, with its laser emission port perpendicularly facing the placement seat. The buzzer is mounted on the other end of the mounting plate and is electrically connected to the laser collimator.

[0009] As a further embodiment of this application, the drive assembly includes a threaded rod, a movable seat, and a motor. The threaded rod is rotatably disposed within the movable groove, the movable seat is slidably engaged with the inner wall of the movable groove, the movable seat is threadedly engaged with the threaded rod, and the motor is mounted on the fixed seat. The output end of the motor is coaxially and fixedly connected to one end of the threaded rod.

[0010] As a further improvement in this application, the support frame is provided with a groove that cooperates with the detection mechanism.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, the elevator guide rail is placed in the receiving cavity by the cooperation of the placement seat and the fixing component. By simultaneously activating two first electric cylinders, the output end of the first electric cylinder drives the abutment plate to move along the inner wall of the receiving cavity. The two abutment plates abut against and clamp the two ends of the two elevator guide rails respectively, which can adapt to elevator guide rails of different lengths, so as to facilitate testing.

[0013] 2. In this utility model, through the cooperation of the detection mechanism and the moving mechanism, the second electric cylinder is activated. The output end of the second electric cylinder drives the slider to move along the inner wall of the T-shape. The slider drives the detection mechanism to move above the placement seat, activating the laser collimator. When the laser beam emitted by the laser collimator irradiates the elevator guide rail and is perpendicular, the moving seat is moved by electric drive. The moving seat drives the mounting plate to move, and the mounting plate drives the laser collimator and buzzer to move. The laser collimator detects the straightness of the elevator guide rail. When the elevator guide rail is deformed (such as bent or offset), the detection point of the laser collimator deviates from the laser reference line, and the laser collimator sends a signal, directly controlling the buzzer to sound an alarm. Through the setting of the moving mechanism, not only can the straightness of multiple end faces of the elevator guide rail be detected, but also compared with manual handheld measuring instrument detection, this detection efficiency is higher, saving manpower and time.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1-4 As shown, this embodiment proposes an elevator guide rail deformation detection device, which is applied to an elevator guide rail 1. The elevator guide rail 1 is T-shaped and includes a base 2, a fixing plate 3, a placement seat 4, a fixing component, and a detection mechanism.

[0022] The fixing plate 3 is fixedly connected to the base 2, and the placement seat 4 is fixedly connected to one end of the fixing plate 3. The placement seat 4 is located on one side of the fixing plate 3. The placement seat 4 has a receiving cavity 5. The cross-sectional area of ​​the receiving cavity 5 is larger than the cross-sectional area of ​​the elevator guide rail 1, which can accommodate elevator guide rails 1 of different sizes and is used to place the elevator guide rail 1.

[0023] like Figure 2 As shown, the fixing component is set on the placement seat 4 to abut and fix the two ends of the elevator guide rail 1. The fixing component includes a first electric cylinder 6 and an abutment plate 7. The first electric cylinder 6 is installed at both ends of the placement seat 4. The output end of the first electric cylinder 6 passes through the side wall of the placement seat 4 and extends into the receiving cavity 5. The output end of the first electric cylinder 6 is fixedly connected to the abutment plate 7. The abutment plate 7 slides with the inner wall of the receiving cavity 5. The receiving cavity 5 can guide the abutment plate 7. The two first electric cylinders 6 are of the same model. When the elevator guide rail 1 is placed in the receiving cavity 5, the two first electric cylinders 6 are activated at the same time. The output end of the first electric cylinder 6 drives the abutment plate 7 to move along the inner wall of the receiving cavity 5. The two abutment plates 7 abut against and clamp the two ends of the two elevator guide rails 1 respectively.

[0024] like Figure 3 As shown, the detection mechanism is movable above the placement seat 4 via a moving mechanism to detect whether the elevator guide rail 1 has deformed. The moving mechanism includes a support frame, a slider 11, and a second electric cylinder 12. One end of the support frame is fixedly connected to the top of the fixed plate 3. The support frame consists of a vertical plate 8 and a horizontal plate 9. One end of the vertical plate 8 is fixedly connected to the top of the fixed plate 3, and the other end of the vertical plate 8 is fixedly connected to one end of the horizontal plate 9. A T-shaped groove 10 is provided on the support frame. The T-shaped groove 10 is provided on the horizontal plate 9. One end of the slider 11 is slidably engaged with the T-shaped groove 10. The slider 11 is a T-shaped block. The second electric cylinder 12 is installed on the support frame. The output end of the second electric cylinder passes through the outer wall of the support frame and extends into the T-shaped groove 10. The output end of the second electric cylinder 12 is fixedly connected to the slider 11. By activating the second electric cylinder 12, the output end of the second electric cylinder 12 drives the slider 11 to move along the inner wall of the T-shaped groove 10. The slider 11 drives the detection mechanism to move above the placement seat 4.

[0025] like Figure 3 and Figure 4As shown, the detection mechanism includes a fixed base 13, a mounting plate 15, a laser collimator 16, and a buzzer 17. One end of the fixed base 13 is fixedly connected to the other end of the slider 11. A movable groove 14 is provided inside the fixed base 13. The mounting plate 15 is movably mounted above the placement seat 4 via a drive assembly. The drive assembly includes a threaded rod 18, a movable seat 19, and a motor 20. The threaded rod 18 is rotatably mounted inside the movable groove 14. The movable seat 19 slides against the inner wall of the movable groove 14 and is threadedly engaged with the threaded rod 18. Telescopic mesh covers 22 are provided on both inner side walls of the movable groove 14. The other ends of the two telescopic mesh covers 22 are fixedly connected to both ends of the movable seat 19, respectively. The motor 20 is mounted on the fixed base 13. The output end of the motor 20 is coaxially fixedly connected to one end of the threaded rod 18. By starting the motor 20, the output end of the motor rotates, driving the threaded rod 18 to rotate. The threaded rod 18 drives the movable seat 19 to move along the inner wall of the movable groove 14. The movable seat 19 drives the mounting plate 15 to move above the placement seat 4.

[0026] It should be added that the moving direction of the movable seat 19 driven by the motor 20 and the moving direction of the fixed seat 13 driven by the second electric cylinder 12 are perpendicular to each other.

[0027] A laser collimator 16 is mounted on one end of the mounting plate 15, with its laser emission port vertically facing the placement base 4. A buzzer 17 is mounted on the other end of the mounting plate 15 and is electrically connected to the laser collimator 16. The laser collimator 16 uses a laser beam as a reference line and, in conjunction with a receiver, detects positional deviations on the surface of the elevator guide rail 1. When the elevator guide rail 1 deforms (e.g., bends or shifts), the detection point of the laser collimator 16 deviates from the laser reference line, and the laser collimator 16 emits a signal, directly controlling the buzzer. The device 17 issues an alarm. To prevent the slider 11 from colliding with the vertical plate 8 when it moves the detection mechanism, the support frame has a groove 21 that matches the detection mechanism. The second electric cylinder 12 drives the slider 11 to move, so that the laser beam emitted by the laser collimator 16 irradiates the elevator guide rail 1 vertically. The moving seat 19 is moved by electric drive, and the moving seat 19 drives the mounting plate 15 to move. The mounting plate 15 drives the laser collimator 16 and the buzzer 17 to move. The laser collimator 16 detects the straightness of the elevator guide rail 1.

[0028] It should be added that the length of the moving groove 14 is greater than the length of the elevator guide rail 1, so as to enable the laser collimator 16 to cover the surface of the elevator guide rail 1.

[0029] Working principle: When the elevator guide rail deformation detection device detects the straightness of the elevator guide rail 1, it detects whether the elevator guide rail 1 has deformed. The elevator guide rail 1 is placed in the receiving cavity 5. By simultaneously activating two first electric cylinders 6, the output end of the first electric cylinder 6 drives the abutment plate 7 to move along the inner wall of the receiving cavity 5. The two abutment plates 7 respectively abut against the two ends of the two elevator guide rails 1 and clamp and fix the elevator guide rail 1.

[0030] By activating the second electric cylinder 12, the output end of the second electric cylinder 12 drives the slider 11 to move along the inner wall of the T-slot 10. The slider 11 drives the detection mechanism to move above the placement seat 4, activating the laser collimator 16. When the laser beam emitted by the laser collimator 16 irradiates the elevator guide rail 1 and is perpendicular, the moving seat 19 is moved by electric drive. The moving seat 19 drives the mounting plate 15 to move. The mounting plate 15 drives the laser collimator 16 and the buzzer 17 to move. The laser collimator 16 detects the straightness of the elevator guide rail 1. When the elevator guide rail 1 is deformed (such as bent or offset), the detection point of the laser collimator 16 deviates from the laser reference line. The laser collimator 16 sends a signal, directly controlling the buzzer 17 to sound an alarm.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
