Description

[0002] During the installation, operation, and maintenance of elevators, the verticality of the elevator guide rails is one of the key indicators to ensure the safe and stable operation of the elevator. If there is a deviation in the verticality of the guide rails, it may cause problems such as jamming, abnormal noise, and increased vibration during elevator operation, and in severe cases, it may even lead to safety accidents. Therefore, accurate detection of the verticality of elevator guide rails is of utmost importance.

[0003] Currently, the industry mostly uses manual measurement with tools such as levels, plumb bobs, or laser line projectors to inspect the verticality of elevator guide rails. This traditional method has several limitations: firstly, manual operation relies on the experience and skills of the inspectors, making it highly subjective and prone to affecting accuracy due to operating techniques and reading errors; secondly, elevator guide rails are typically long, and manual point-by-point inspection is not only inefficient and labor-intensive, but also makes it difficult to achieve continuous, dynamic inspection of the entire guide rail, potentially missing local verticality deviations.

[0004] Therefore, in view of the problems of low efficiency, poor accuracy and weak adaptability of existing detection methods, there is an urgent need for an elevator guide rail verticality detection device that can be quickly installed and fixed, moved stably and accurately detected, and can adapt to guide rails of different specifications, so as to meet the elevator industry's requirements for high efficiency, accuracy and safety in guide rail verticality detection.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] like Figures 1-6 As shown, the elevator guide rail verticality detection device of this utility model includes a mounting shell 1 and a signal receiving plate 2. The mounting shell 1 is provided with a fixing component 3, a driving component 4 extending to its outer side, a transmitting shell 5, and a signal transmitting component 6 adapted to the signal receiving plate 2.

[0030] Furthermore, the fixing component 3 includes a sliding block 31, an adjusting bidirectional screw 32, and a rolling component 33. The mounting shell 1 is slidably connected to the sliding blocks 31 located on both sides. The mounting shell 1 is movably connected to the adjusting bidirectional screw 32 threadedly connected to the sliding blocks 31. Each sliding block 31 is provided with a rolling component 33 that is adapted to each other. The rolling component 33 includes a telescopic screw 331, a telescopic column 332, and a rolling wheel 333. Each sliding block 31 is movably connected to the telescopic screw 331. Each sliding block 31 is movably connected to the telescopic column 332 threadedly connected to the telescopic screw 331. Each telescopic column 332 is movably connected to a rolling wheel 333 that is adapted to each other. The rolling wheel 333 is made of anti-slip material and is shaped like a frustum.

[0031] By means of the threaded engagement between the sliding block 31 and the adjusting bidirectional screw 32, the distance between the two sliding blocks 31 can be easily adjusted by rotating the adjusting bidirectional screw 32 to adapt to elevator guide rails of different widths. In the rolling assembly 33, rotating the telescopic screw 331 can adjust the extension length of the telescopic column 332, thereby changing the position of the rolling wheel 333 to ensure that it fits tightly with the guide rail and improves the adaptability of the device installation. The frustum-shaped rolling wheel 333 made of anti-slip material not only increases the friction with the guide rail to prevent slippage, but also better fits the side shape of the guide rail, enhancing the installation stability of the device on the guide rail and ensuring that the device will not easily shift during the testing process.

[0032] Furthermore, the drive assembly 4 includes a dual-axis motor 41, a drive gear 42, and a drive component 43. The mounting housing 1 is equipped with the dual-axis motor 41, and each output end of the dual-axis motor 41 is equipped with a drive gear 42. Inside the mounting housing 1, there is a drive component 43 that is connected to the drive gear 42 and extends to the outside of the mounting housing 1. The drive component 43 includes a drive shaft 431, a drive wheel 432, a synchronous pulley 433, and a synchronous belt 434. The mounting housing 1 is movably connected to drive shafts 431 that are symmetrically distributed front and back. Each drive shaft 431 is equipped with a drive wheel 432 that is symmetrically distributed left and right and extends to the outside of the mounting housing 1. The drive shaft 431 on the side closer to the drive gear 42 is equipped with a drive gear 44 that meshes with the drive gear 42. Each drive shaft 431 is equipped with a synchronous pulley 433, and the synchronous pulley 433 is fitted with the same synchronous belt 434.

[0033] The dual-axis motor 41 drives the drive shaft 431 through the meshing of the drive gear 42 and the driving gear 44. The driving wheel 432 rotates accordingly, enabling the device to move along the guide rail without manual pushing, saving manpower and making it easy to control the movement speed. The symmetrically distributed drive shafts 431 rotate synchronously under the action of the synchronous pulley 433 and the synchronous belt 434, ensuring that the front and rear drive wheels 432 move in unison, avoiding deviation or jamming when the device moves, and enabling the device to move smoothly along the guide rail, ensuring the continuity and stability of the detection of the guide rail at different positions.

[0034] Furthermore, the signal transmitting assembly 6 includes a fixing spring 61 and a signal transmitting head 62. The transmitting housing 5 is provided with a fixing spring 61, and the other end of the fixing spring 61 is provided with a signal transmitting head 62 adapted to the signal receiving board 2.

[0035] The fixed spring 61 provides elastic support for the signal transmitter 62, which can buffer the slight vibration during the movement of the device, keep the signal transmitter 62 in a relatively stable posture, and reduce the signal transmission deviation caused by vibration. At the same time, the elasticity of the fixed spring 61 allows the signal transmitter 62 to better adapt to the relative position change between itself and the signal receiver 2, ensuring the accuracy of signal transmission and providing a basis for the reliability of subsequent verticality detection data.

[0036] Furthermore, the mounting housing 1 is provided with a sliding assembly 7 extending to the outside of the mounting housing 1 and adapted to the signal transmitting assembly 6. The sliding assembly 7 includes a mounting sleeve 71, a sliding probe 72, a mounting plate 73, and a return spring 74. The mounting housing 1 is provided with mounting sleeves 71 arranged in a rectangular array. The mounting sleeves 71 are movably connected to the inside of the mounting sleeves 71, extending to the outside of the mounting housing 1 and contacting the signal transmitting head 62. Each sliding probe 72 is provided with a mounting plate 73 arranged symmetrically on the top and bottom. Each mounting plate 73 is provided with a return spring 74 whose other end is connected to the mounting sleeve 71. Both ends of the sliding probe 72 are spherical.

[0037] The sliding probes 72, arranged in a rectangular array, can fully contact the guide rail surface. When there is unevenness on the guide rail surface, the sliding probes 72 can slide flexibly within the mounting sleeve 71, thereby pushing the signal transmitter 62 in contact with them to move, thus detecting whether there is unevenness on the guide rail surface. The spherical design at both ends of the sliding probes 72 reduces friction and wear with the guide rail surface and the signal transmitter 62, extending the service life of the component. At the same time, it ensures that the sliding probes 72 can always maintain contact with the signal transmitter 62, stably transmitting the shape changes of the guide rail surface to the signal transmitter 62, further improving the accuracy of detection.

[0038] Furthermore, the mounting housing 1 is provided with a level bubble 8 that is placed perpendicular to the fixing component 3.

[0039] A spirit level 8 is installed on the mounting housing 1, perpendicular to the fixing component 3, which can be used for rapid calibration during the device installation stage. Since the spirit level 8 is perpendicular to the fixing component 3, after the fixing component 3 is installed and fixed to the elevator guide rail, the centered state of the bubble in the spirit level 8 can be observed to intuitively determine whether the whole device is in a horizontal or vertical reference position perpendicular to the guide rail, ensuring that the installation direction of the fixing component 3 is consistent with the verticality detection reference of the guide rail. This setting can avoid the detection reference deviation caused by the device's own installation tilt, laying the foundation for the precise cooperation between the subsequent signal transmitting component 6 and the signal receiving board 2, further improving the initial positioning accuracy of the entire detection process, and reducing the detection error caused by improper device installation posture.

[0040] The working principle of the elevator guide rail verticality detection device of this utility model is as follows: the device achieves a stable connection with the elevator guide rail through the fixing component 3. Rotating the adjusting bidirectional screw 32 can adjust the distance between the sliding blocks 31 on both sides. In conjunction with the telescopic screw 331 in the rolling component 33, the length of the telescopic column 332 is adjusted so that the frustum-shaped anti-slip rolling wheel 333 fits tightly against the side of the guide rail. Finally, by observing the level bubble 8, when the level bubble 8 is placed horizontally, the installation and fixation of the device on the guide rail can be completed. Then, the signal receiving plate 2 is horizontally installed at the other end of the elevator guide rail, and the receiving point of the signal transmitter 62 is located in the center of the signal receiving plate 2.

[0041] During testing, the drive assembly 4 provides the power for movement: the dual-axis motor 41 drives the drive gear 42 to rotate, and through the meshing transmission with the drive gear 44, the drive shaft 431 rotates. Under the synergistic action of the synchronous pulley 433 and the synchronous belt 434, the front and rear drive shafts 431 rotate synchronously, and the drive pulley 432 rolls along the guide rail, realizing the smooth movement of the device.

[0042] During the movement, the sliding probe 72 in the sliding assembly 7 contacts the guide rail surface. When the guide rail is uneven, the sliding probe 72 slides in the mounting sleeve 71 and is adaptively adjusted by the reset spring 74, thereby pushing the signal transmitter 62 in contact with it to move, thereby detecting whether there is unevenness on the guide rail surface. Its spherical end transmits the change in the shape of the guide rail surface to the signal transmitter 62 of the signal transmitter assembly 6. The fixing spring 61 ensures that the signal transmitter 62 is always in contact with the sliding probe 72 and maintains a stable posture. The signal transmitter 62 transmits the corresponding signal to the signal receiving board 2.

[0043] If there is a verticality deviation in the elevator guide rail, the relative position of the signal transmitter 62 and the signal receiver 2 will change, and the signal received by the signal receiver 2 will change accordingly. By analyzing the trajectory of the signal change, the verticality of the guide rail can be determined, thus realizing the automated detection of the verticality of the elevator guide rail.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
