The overall detection efficiency is low and it is difficult to meet the requirements of high-efficiency detection. Therefore, an automatic elevator guide rail wear detection equipment is needed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic elevator guide rail wear detection device, comprising an operating table, four anti-slip support pads fixedly connected to the bottom of the operating table, a controller fixedly connected to the top of the operating table, a display screen fixedly connected to the surface of the controller, four pillars fixedly connected to the top of the operating table, two mounting plates fixedly connected to the surface of the four pillars, hydraulic clamping components fixedly connected to one side surface of each of the two mounting plates, an elevator guide rail to be tested provided on the top of the operating table, a detection adjustment plate fixedly connected to one end of each of the four pillars, an adjustment groove provided inside the detection adjustment plate, and two adjustment screw rings slidably connected to the inner wall of the adjustment groove. The two adjusting screw rings are internally threaded with bidirectional threaded screws, one end of which is fixedly connected to a drive motor. The detection adjustment plate has two guide grooves inside, and two guide rods are slidably connected to the inner walls of the two guide grooves.

[0011] As a preferred embodiment, the cleaning scraper is in contact with the detection surface of the elevator guide rail to be tested.

[0012] As a preferred embodiment, the detection assembly plate is located below the arc-shaped groove protective cover.

[0013] By setting guide grooves and guide rods, the guide rods can provide precise positioning and guidance for the detection combination plate and the cleaning scraper when they move within the guide grooves, ensuring that both remain stable during movement and avoiding deviation or shaking. This, in turn, ensures the detection stability of the detection device and the reliability of the cleaning operation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by incorporating an electric push rod, enables the displacement sensor to approach and the cleaning scraper to adhere to the detection surface of the elevator guide rail under test. The position can be precisely adjusted according to the specific dimensions, enhancing the flexibility and practicality of the detection device. Before testing, the drive motor and bidirectional threaded screw drive the cleaning scraper to remove impurities from the surface of the elevator guide rail, preventing any impact on the accuracy of the displacement sensor's detection. During testing, two adjusting screw rings drive two sets of detection combination plates in opposite directions for parallel testing, significantly improving efficiency compared to single-line testing. Throughout the testing process, the arc-shaped groove protective cover and the detection adjustment plate protect the electric push rod, detection combination plates, and the bidirectional threaded screw connection structure, effectively isolating foreign objects and providing a reliable environment for stable adjustment of the detection components.

Two adjustment screw rings 11 are slidably connected to the inner walls of the adjustment groove 10. A double-threaded screw rod 12 is threaded into the inner walls of the two adjustment screw rings 11. A drive motor 13 is fixedly connected to one end of the double-threaded screw rod 12. The plate 9 also has two guide grooves 14 inside. Two guide rods 15 are slidably connected to the inner walls of the two guide grooves 14. Electric push rods 16 are fixedly connected to the inner walls of the four guide rods 15. Detection assembly plates 17 are fixedly connected to the telescopic ends of the four electric push rods 16. Four detection assembly plates 17... Displacement sensors 18 are fixedly connected to one side surface of the plate 17, and cleaning scrapers 19 are fixedly connected to both ends of the four detection combination plates 17. Alarms 20 are fixedly connected to the other side surface of the four detection combination plates 17. Arc-shaped groove protective covers 21 are fixedly connected to both sides of the detection adjustment plate 9. By setting an electric push rod 16, the electric push rod 16 can drive the displacement sensors 18 to approach and the cleaning scrapers 19 to fit against the detection surface of the elevator guide rail 8 to be tested. The position can be precisely adjusted according to its specific size, improving the flexibility and practicality of the detection device. Before detection, the drive... The motor 13 and the bidirectional threaded screw 12 can drive the cleaning scraper 19 to remove impurities from the surface of the elevator guide rail 8 under test, so as to avoid affecting the detection accuracy of the displacement sensor 18. During the test, the two adjusting screw rings 11 can drive the two sets of detection combination plates 17 to perform parallel detection in opposite directions, which greatly improves efficiency compared with single-line detection.

[0031] Working principle and usage process of this utility model:

[0032] When the automatic elevator guide rail wear detection equipment is working, the elevator guide rail 8 to be tested is first fixed by the hydraulic clamping component 7. Then, the electric push rod 16 drives the displacement sensor 18 to approach the detection surface of the elevator guide rail 8 to be tested, and at the same time drives the cleaning scraper 19 to fit against the detection surface of the elevator guide rail 8 to be tested. The controller 3 starts the drive motor 13, which drives the bidirectional threaded screw 12 to rotate, so that the two adjusting screw hole rings 11 move in opposite directions along the guide groove 14 in the adjusting groove 10, thereby driving the electric push rod 16 and the detection combination plate 17 to move, and carry out two sets of parallel detection operations on the elevator guide rail 8 to be tested.

[0033] Before testing, the cleaning scraper 19 is simultaneously attached to the surface of the elevator guide rail 8 to be tested, and the impurities on the test surface are cleaned to minimize the impact of impurities on the detection accuracy of the displacement sensor 18. After that, the displacement sensor 18 detects the wear data of the elevator guide rail 8 under test in real time and transmits it to the controller 3. The display screen 4 displays the test results simultaneously. When the wear exceeds the preset threshold, the alarm 20 will automatically alarm.

[0034] Throughout the testing process, the arc-shaped groove protective cover 21 protects the connection structure between the electric push rod 16 and the testing combination plate 17. The synchronous testing design of the two sets of testing combination plates 17 enables the parallel execution of the testing tasks of the elevator guide rail 8 under test, effectively improving the testing efficiency.

[0035] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
