Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rail flatness detection, in particular to an elevator guide rail flatness detection device. Background Art

[0002] The manufacturing process of elevator guide rails and their subsequent flatness testing are the cornerstones for ensuring the safety and stability of elevator operation. The importance of this link is self-evident. Starting from the selection of steel plate raw materials, flatness testing is a strict screening threshold, which ensures that the surface of the steel plate used to make the guide rails is flat and defect-free, providing a good foundation for subsequent processing.

[0003] However, in many factories, workers mostly use their naked eyes or handheld testing instruments to evaluate the flatness of steel plates, but these two methods undoubtedly have great limitations.

[0004] First, naked-eye inspection is affected by many factors, such as light, angle, and visual fatigue, and it is difficult to ensure consistency and accuracy of each judgment. Even experienced workers may miss some minor uneven areas due to momentary negligence or fatigue.

[0005] Secondly, although handheld instrument detection has improved the accuracy of detection to a certain extent, it also has limitations. These instruments often require workers to operate manually, and the accuracy of their measurement results depends largely on the workers' operating skills and experience. In addition, when handheld instruments measure large areas of steel plates, they are not only inefficient, but may also cause unstable measurement data due to human factors.

[0006] Therefore, this detection method that relies on manual or simple handheld instruments is particularly insufficient under the high-precision requirements of elevator guide rail production. It cannot provide stable and reliable flatness data support for subsequent guide rail production, nor can it ensure that each steel plate can meet the established quality standards. This situation not only affects the overall quality of elevator guide rails, but also increases safety hazards during elevator operation. Utility Model Content

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0029] A device for detecting flatness of elevator guide rails according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 5 As shown, an elevator guide rail flatness detection device of an embodiment of the utility model includes an operating platform 1, a sliding detection device 2, a fixed movable device 3, a steel plate 4 and a control end 5, wherein the sliding detection device 2 includes two sliding detection components 21, wherein the two sliding detection components 21 are respectively arranged at both ends of the operating platform 1, the fixed movable device 3 includes a moving component 31 and a fixed component 32, wherein the moving component 31 is slidably arranged on the operating platform 1, and the fixed component 32 is arranged on the moving component 31, the steel plate 4 is slidably arranged on the two sliding detection components 21, and the steel plate 4 is movably connected to the fixed component 32, and the control end 5 is arranged on one side of the operating platform 1, and the control end 5 is electrically connected to the two sliding detection components 21, the moving component 31 and the fixed component 32.

[0031] Among them, it can be understood that when it is necessary to detect the flatness of the steel plate 4, the steel plate 4 is placed on two sliding detection components 21, and the two ends of the steel plate 4 slide on the two sliding detection components 21 respectively. The two sliding detection components 21 can fit the surface of the steel plate 4 tightly and slide smoothly with the movement of the steel plate 4. The built-in high-precision sensor can capture the tiny ups and downs on the surface of the steel plate 4 in real time and convert them into accurate digital signals for analysis. It can quickly evaluate the flatness state of the steel plate 4 and provide instant feedback on the detection results. At the same time, the steel plate 4 is fixed by the fixing component 32, and the steel plate 4 is driven to move forward at a stable speed by the moving component 31, ensuring that the steel plate 4 remains stable and shake-free during the movement, thereby providing a stable and reliable detection environment for the two sliding detection components 21, which not only significantly improves the detection efficiency and shortens the detection cycle, but also greatly enhances the accuracy and reliability of the detection results, and the flatness data of the steel plate 4 that has been finally detected is displayed through the control terminal 5.

[0032] In one embodiment of the present invention, Figure 4 As shown, the two sliding detection components 21 each include a support frame 211, two buffer pillars 212, a first rotating wheel 213, a mounting seat 214, a second rotating wheel 215 and two pressure sensors 216, wherein the support frame 211 is arranged at both ends of the operating table 1, the two buffer pillars 212 are respectively movably arranged at both ends of the support frame 211, the first rotating wheel 213 is rotatably arranged on the support frame 211, the mounting seat 214 is fixedly connected to the top of the two buffer pillars 212, the second rotating wheel 215 is rotatably arranged on one side of the mounting seat 214, the two pressure sensors 216 are respectively arranged at the bottom of the two buffer pillars 212, and the steel plate 4 is slidably arranged between the two first rotating wheels 213 and the two second rotating wheels 215.

[0033] Among them, it can be understood that the steel plate 4 is placed between the two support frames 211, and the steel plate 4 is placed on the two buffer pillars 212, and the sliding of the steel plate 4 is achieved by the first rotating wheel 213 and the second rotating wheel 215. At the same time, the two buffer pillars 212 drive the first rotating wheel 213 and the second rotating wheel 215 to fit closely to the surface of the steel plate 4, and slide smoothly with the movement of the steel plate 4. The two pressure sensors 216 can capture the tiny ups and downs on the surface of the steel plate 4 in real time and convert them into accurate digital signals for analysis, so that the flatness state of the steel plate 4 can be quickly evaluated and the detection results can be fed back instantly.

[0034] In one embodiment of the present invention, Figure 2As shown, the moving assembly 31 includes a driving motor 311, two bearing seats 312, a rotating rod 313, a connecting plate 314, two slide rails 315 and two sliders 316, wherein the driving motor 311 is arranged on one side of the operating table 1, the two bearing seats 312 are respectively arranged at the bottom of the operating table 1, the rotating rod 313 is rotatably arranged between the two bearing seats 312, and one end of the rotating rod 313 is connected to the output end of the driving motor 311, the connecting plate 314 is slidably arranged on the rotating rod 313, and the connecting plate 314 is threadedly connected to the rotating rod 313, the two slide rails 315 are respectively arranged on the operating table 1, and the two sliders 316 are respectively slidably arranged on the two slide rails 315.

[0035] It can be understood that the driving motor 311 drives the rotating rod 313 to rotate between the two bearing seats 312. When the rotating rod 313 rotates, the connecting plate 314 slides on the rotating rod 313, and the two sliders 316 can slide on the two slide rails 315.

[0036] It should be noted that the driving motor 311 described in this embodiment is a bidirectional motor, and thus can drive the rotating rod 313 to rotate in different directions, and thus can drive the connecting plate 314 to slide in different directions.

[0037] In one embodiment of the present invention, Figure 5 As shown, the fixing assembly 32 includes a sliding plate 321, an electric push rod 322, a fixed buckle 323, a movable buckle 324, a toggle block 325 and a pressing block 326, wherein the sliding plate 321 is arranged on two sliders 316, the electric push rod 322 is arranged on one side of the sliding plate 321, the fixed buckle 323 is arranged on the sliding plate 321, the movable buckle 324 is arranged in the fixed buckle 323, the toggle block 325 is movably arranged in the movable buckle 324, one end of the toggle block 325 is movably connected to the movable buckle 324, and one lower end of one side is movably connected to the fixed buckle 323, and the pressing block 326 is fixedly connected to the other end of the toggle block 325.

[0038] Among them, it can be understood that when the rotating rod 313 rotates, the connecting plate 314 will slide on the rotating rod 313, and at the same time will drive the sliding plate 321 to slide, and at the same time drive the two sliders 316 to slide on the two slide rails 315, and the electric push rod 322 will push the movable buckle 324 forward and backward to move on the fixed buckle 323, and at the same time drive the toggle block 325 to rise and fall, and at the same time drive the pressing block 326 to rise and fall, so that the steel plate 4 is fixed by the pressing block 326.

[0039] In one embodiment of the present invention, Figure 1As shown, the control end 5 is electrically connected to the electric push rod 322 , the driving motor 311 and the two pressure sensors 216 , respectively.

[0040] It can be understood that the overall control of the electric push rod 322, the drive motor 311 and the two pressure sensors 216 is achieved through the control terminal 5, making the operation more convenient.

[0041] It should be noted that the control method of the present application can be automatically controlled by the controller inside the control terminal 5. The control method of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, the present application is mainly used to protect mechanical structures, so the present application will no longer explain the control method and circuit connection in detail.

[0042] Specifically, in the actual implementation process, when it is necessary to detect the flatness of the steel plate 4, the steel plate 4 is placed between the two support frames 211, and the steel plate 4 is placed on the two buffer pillars 212. The first rotating wheel 213 and the second rotating wheel 215 are used to slide the steel plate 4. At the same time, the two buffer pillars 212 drive the first rotating wheel 213 and the second rotating wheel 215 to fit closely to the surface of the steel plate 4, and slide smoothly with the movement of the steel plate 4. The two pressure sensors 216 can capture the tiny fluctuations on the surface of the steel plate 4 in real time and convert them into accurate digital signals for analysis. The flatness state of the steel plate 4 can be quickly evaluated and the detection results can be fed back instantly.

[0043] The electric push rod 322 is pushed back and forth to drive the movable buckle 324 to move on the fixed buckle 323, and at the same time drive the toggle block 325 to rise and fall, and at the same time drive the pressing block 326 to rise and fall. Therefore, the steel plate 4 is fixed by the pressing block 326, and the rotating rod 313 is driven to rotate between the two bearing seats 312 by the driving motor 311. When the rotating rod 313 rotates, the connecting plate 314 will slide on the rotating rod 313, and the two sliders 316 can slide on the two slide rails 315. When the rotating rod 313 rotates, the connecting plate 314 will slide on the rotating rod 313, and at the same time, it will drive the sliding plate 321 to slide, and at the same time drive the two sliders 316 to slide on the two slide rails 315, and at the same time drive the steel plate 4 to move forward at a stable speed, ensuring that the steel plate 4 remains stable and shake-free during the movement, thereby providing a stable and reliable detection environment for the sliding detection device 2.

[0044] In summary, an elevator guide rail flatness detection device according to an embodiment of the utility model is provided with a sliding detection device, which can closely fit the surface of the steel plate. It has a built-in high-precision sensor, which can capture the slight ups and downs on the surface of the steel plate in real time, and can quickly evaluate the flatness state of the steel plate and provide instant feedback on the detection results. At the same time, the fixed moving device is responsible for driving the steel plate to move forward at a stable speed, ensuring that the steel plate remains stable and shake-free during the movement, thereby providing a stable and reliable detection environment for the sliding detection device.
