Abstract
Description
Technical Field
[0001] This application relates to the field of elevator testing equipment technology, and more specifically, to an elevator acceleration and deceleration tester. Background Technology
[0002] During the installation, commissioning, maintenance, and other stages of elevator operation, it is necessary to test the elevator's acceleration and deceleration to ensure its safe operation. An elevator acceleration and deceleration tester is a professional instrument specifically designed to measure the acceleration and deceleration of an elevator during operation.
[0003] In existing technologies, elevators experience vibrations or slight swaying during vertical movement after a period of operation. When an acceleration / deceleration meter is placed on the elevator floor, the vibration amplitude varies slightly at different locations. This vibration and swaying can cause errors in the meter's results. Therefore, to ensure relatively accurate test results, it is best to place the instrument in the center of the elevator, where the vibration amplitude is smaller than at the corners, minimizing its impact on the test results. Furthermore, some acceleration / deceleration meters, in addition to detecting vertical acceleration / deceleration, also detect abnormalities such as swaying and vibration during elevator operation. Therefore, they are equipped with high-precision triaxial sensors to detect the range of horizontal swaying. For accuracy, the meter also needs to be placed in the center of the elevator, and the X and Y axes of its internal triaxial sensor must be parallel to the two right-angled sides of the elevator. In actual testing, workers determine the elevator's center position based on its dimensions, which requires measurement and is cumbersome and prone to significant errors.
[0004] Therefore, it is necessary for the inventors to design a new elevator acceleration and deceleration detector to overcome the above problems. Summary of the Invention

Two rotating arms are rotatably mounted on the detector body, and the rotation axes of the two rotating arms are collinear. A laser emitting component is fixedly mounted on each of the two rotating arms. The line of the laser emitted by the laser emitting component passes through the rotation axis of the rotating arm.

[0027] In addition, the term "multiple" should mean two or more.
[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0029] like Figures 1 to 4 As shown, an elevator acceleration / deceleration detector includes a detector body 1. Two rotating arms 2 are rotatably mounted on the detector body 1. The rotation axes of the two rotating arms 2 are collinear. A laser emitting component 3 is fixedly mounted on each of the two rotating arms 2. The line of the laser emitted by the laser emitting component 3 passes through the rotation axis of the rotating arm 2. A positioning component and a driving component are also fixedly mounted between the rotating arm 2 and the detector body 1.
[0030] Specifically, when determining the center position of the elevator, based on the elevator's length and width dimensions, the two rotating arms 2 are adjusted to positions parallel to the elevator's two diagonals. At this point, the laser emitting components 3 are activated. When the laser beams emitted by the two laser emitting components 3 land at the two corner points on the same side of the elevator, it proves that the rotation axis of the rotating arms 2 coincides with the elevator's central axis. This embodiment cleverly utilizes the fact that the laser's path is parallel to the diagonals of the rectangle and that the laser's landing point is at the elevator's corner, efficiently determining the elevator's center position, eliminating the need for manual measurement, simplifying operation, increasing efficiency, and minimizing error.
[0031] The positioning assembly includes a sliding groove 4, a limiting groove 5, and a screw 6. The sliding groove 4 extends through the rotating arm 2, and the limiting groove 5 is formed on the detector body 1. The screw 6 is simultaneously slidably inserted into both the sliding groove 4 and the limiting groove 5. A nut 7, which cooperates with the screw 6, is also provided in the limiting groove 5. When the two rotating arms 2 rotate to a position parallel to the diagonal, they are fixed by the positioning assembly. Tightening the screw 6 at this time achieves fixation. When adjusting their position, loosening the screw 6 allows it to slide in the sliding groove 4 and the nut 7 to slide in the limiting groove 5 until they reach the designated position. It should be noted that the nut 7 should not fall out of the limiting groove 5. It can be kept in sliding contact with the bottom surface of the limiting groove 5 by a limiting method. The specific limiting method will not be described in detail here.
[0032] The width of the slide groove 4 is equal to the diameter of the screw 6, and the width of the limiting groove 5 is equal to the distance between opposite sides of the nut 7. Specifically, the width of the slide groove 4 is equal to the diameter of the screw 6 to prevent the screw 6 from wobbling in the slide groove 4. Similarly, the nut 7 should not wobble in the limiting groove 5.
[0033] The drive assembly includes a sliding plate 11, the sliding direction of which is the same as the length direction of the limiting groove 5, and the sliding plate 11 is rotatably connected to the screw 6. Specifically, when adjusting the position of the rotating arm 2, the screw 6 is moved by pushing the sliding plate 11, which in turn moves the rotating arm 2 to achieve adjustment.
[0034] The detector body 1 is also provided with a receiving groove 8, in which the sliding plate 11 slides. The receiving groove 8 is connected to the limiting groove 5. The screw 6 passes through the limiting groove 5 and its bottom is rotatably connected to the sliding plate 11. Specifically, the sliding plate 11 is set inside the detector body 1, and pushing the sliding plate 11 can make the sliding plate 11 move along the length direction of the limiting groove 5.
[0035] like Figure 2 As shown, a displacement indicator assembly is also provided between the slide plate 11 and the detector body 1. The displacement indicator assembly includes a scale line 9 and an arrow indicator plate 10. The scale line 9 is fixedly installed on the detector body 1, and the arrow indicator plate 10 is fixedly connected to the slide plate 11. Specifically, for example, if the length and width of the elevator are 2m and 1.5m respectively, and the distance between the rotation axis of the rotating arm 2 and the center line of the limiting groove 5 is 20cm, then the horizontal distance between the center axis of the bolt and the rotation axis of the rotating arm 2 is 20cm. Then, by simply moving the bolt until the vertical distance between its center axis and the rotation axis of the rotating arm 2 is 15cm, the rotating arms 2 on both sides can be made parallel to the two diagonals of the elevator simultaneously.
[0036] The sliding plate 11 is rotatably connected to the screws 6 on both sides. Specifically, the position of the two rotating arms 2 can be adjusted simultaneously by pushing the sliding plate 11.
[0037] The laser emitting assembly 3 includes a laser pointer, which is fixedly mounted on the rotating arm 2 by a snap-fit mechanism. Specifically, the laser pointer is detachable for easy replacement and maintenance.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
