[0002] With the acceleration of urbanization and the booming development of high-rise buildings, the demand and frequency of use of elevators as vertical transportation tools continue to rise. As the core guiding component for the operation of elevator cars and counterweights, the straightness accuracy of elevator guide rails directly determines the smoothness, comfort and safety of elevator operation. Therefore, straightness detection and calibration devices are needed to detect the straightness of elevator guide rails to ensure high-quality operation of elevators.

[0003] However, existing straightness testing and calibration devices are not convenient for centering and fixing the guide rail during use, making it difficult to ensure that the guide rail is in a stable and centered state during testing. Multiple adjustments are required, which reduces the efficiency of testing. Utility Model Content

[0004] The purpose of this invention is to provide an elevator guide rail straightness detection and calibration device. By setting a centering positioning part, it solves the problem that existing straightness detection and calibration devices are not convenient for centering and fixing the guide rail during use, making it difficult to ensure that the guide rail is in a stable and centered state during testing, requiring multiple adjustments, thus reducing the efficiency of testing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an elevator guide rail straightness detection and calibration device, comprising a base plate, and further comprising: a detection unit mounted on the top of the base plate; a centering positioning unit disposed above the base plate; a flipping unit disposed on the top of the base plate; the centering positioning unit includes a clamping assembly disposed on the base plate; and a power assembly disposed above the base plate; the clamping assembly includes a worm gear disposed above the base plate, two arc-shaped rods fixedly connected to the front side of the worm gear, U-shaped sliders slidably connected to the outer walls of the two arc-shaped rods, a connecting member disposed on the left side of the two U-shaped sliders, and a clamping member disposed between the two U-shaped sliders; wherein, the two arc-shaped rods are arranged in a circumferential array on the worm gear, and the power assembly provides reliable positioning assurance for straightness detection.

[0007] Furthermore, the detection unit includes a bracket fixedly connected to the top of the base plate, and a flatness measuring instrument is fixedly connected to the top of the bracket; wherein, both the base plate and the flatness measuring instrument are horizontally arranged, the flipping unit includes a support assembly installed on the top of the base plate; and a rotating assembly disposed above the base plate.

[0008] Furthermore, the power assembly includes a housing disposed above the base plate, the top of which is connected to a rectangular shell, and a power component is disposed on the rectangular shell; wherein, the inner wall of the housing is rotatably connected to a worm gear, and the power assembly provides power support for the operation of the central positioning part.

[0009] Furthermore, the support assembly includes a support frame fixedly connected to the top of the base plate, through which a hollow shaft passes, and the outer wall of the hollow shaft is fixedly connected to the outer shell; wherein, the outer wall of the support frame is rotatably connected to the hollow shaft, and the support assembly provides a structural carrier for the rotation of the guide rail.

[0010] Furthermore, the rotating assembly includes a motor fixedly connected to the base plate. The output shaft of the motor is fixedly connected to a second rotating shaft via a coupling. A first gear is fixedly connected to the outer wall of the second rotating shaft, and a second gear is fixedly connected to the outer wall of the hollow shaft. The hollow shaft meshes with the second gear. The left side of the second rotating shaft extends out of the support frame. The first gear is fixedly connected to the extension of the second rotating shaft. The rotating assembly enables convenient flipping of the guide rail, so that the straightness detection of different surfaces of the guide rail does not require reassembly and disassembly.

[0011] Furthermore, the connector includes rectangular connecting sliders fixedly connected to the left side of the two U-shaped sliders respectively, and two rectangular grooves are provided on the outer shell.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting a centering positioning part, the clamping component and the power component work together to fix the elevator guide rail in a centered position. The power component provides power to drive the worm gear in the clamping component to rotate, causing the two arc-shaped rods distributed in a circular array to move. Then, through the linkage of the U-shaped slider, the connecting part and the clamping part, the two clamping plates move closer to each other, clamping the guide rail in a centered position. This ensures that the guide rail is in a stable and centered state during the inspection, without much adjustment. It provides a reliable positioning basis for subsequent inspection work and avoids the efficiency of straightness inspection being affected by the positional deviation of the guide rail.

[0015] 2. By setting up a flipping part, the rotating component is driven by a motor and gear transmission to make the hollow shaft in the support component rotate, which in turn drives the parts connected to the hollow shaft and the clamped guide rail to flip together. This allows the guide rail to be conveniently inspected on the other side without disassembling and reinstalling after the straightness of one side is completed, which simplifies the operation process, further improves the inspection efficiency, and ensures that the straightness of different sides of the guide rail can be inspected.

[0030] A specific application of this embodiment is as follows: In use, the elevator guide rail to be tested is inserted into the hollow shaft 312, positioning it between the two clamping plates 217. Then, the rotating shaft 223 is rotated. The rotating shaft 223 drives the worm wheel 211 in the outer shell 221 to rotate via the worm gear 224 in the rectangular shell 222. Consequently, the two arc-shaped rods 212 perform circular motion around the axis of the worm wheel 211. The two arc-shaped rods 212 respectively drive the two rectangular connecting sliders 214 to move closer to each other within the two rectangular grooves 215 via the U-shaped sliders 213 on them. Then, the two rectangular connecting sliders 214 respectively drive the two clamping plates 217 to move closer to each other via the two connecting rods 216, clamping the guide rail. In this way, the guide rail is centered and fixed, and the straightness measuring instrument 113 on the bracket 112 can be used for testing. The straightness of the guide rail is checked, and then the motor 321 on the support frame 311 is turned on. The motor 321 drives the gear 323 to rotate through the second shaft 322. The gear 323 drives the hollow shaft 312 to rotate through the second gear 324. The hollow shaft 312 drives the outer shell 221 to rotate, thereby driving the guide rail to flip through the centering positioning part 2. After the flipping is completed, the motor 321 is turned off, and the straightness of the other side of the guide rail can be checked. The flatness measuring instrument 113 is a laser flatness measuring instrument G600. Its working principle is: based on laser technology, using the principle of self-collimating optical tube, through a high-precision laser sensor and signal processing interface board, it realizes high-precision, non-contact measurement of the object being measured. It can be used to measure the straightness and flatness of the guide rail, which can improve measurement efficiency and safety.
