Technical Field

[0001] This utility model relates to the technical field of elevator maintenance and testing, specifically to a laser rangefinder for elevator maintenance. Background Technology

[0002] Laser rangefinders use laser beams to measure distances with extremely high precision. In elevator maintenance, accurate measurement is crucial for ensuring repair quality and safe elevator operation. For example, measuring the straightness and verticality of elevator tracks, as well as the distance between the elevator car and the hoistway, requires high-precision measuring tools to ensure data accuracy, thereby guiding maintenance work and guaranteeing the stability and safety of the elevator.

[0003] In elevator maintenance, existing laser rangefinders have significant drawbacks. Maintenance personnel often need to bend over and reach into the elevator shaft to perform measurements, which not only places them in a dangerous working environment, increasing safety risks, but also greatly limits the convenience and accuracy of the measurements. The bending of the body and the complex spatial layout within the shaft make it difficult for maintenance personnel to operate the laser rangefinder stably and accurately, thus affecting measurement efficiency and result accuracy. Utility Model Content

[0004] This invention provides a laser rangefinder for elevator maintenance, which can solve the problem that maintenance personnel often need to bend their bodies and probe into the elevator shaft to perform measurement operations in the prior art.

[0005] A laser rangefinder for elevator maintenance includes a laser rangefinder body, a support base, a rotating shaft, a connecting sleeve, a telescopic rod, and a controller. The laser rangefinder body has a display screen and operation buttons on one side, with the operation buttons located below the display screen. A laser emitter is embedded in the center of the top of the laser rangefinder body. The support base is detachably mounted on the other side of the laser rangefinder body. The rotating shaft is hinged to the bottom of the support base. Specifically, a hinge frame is fixedly mounted on the bottom of the support base, and a hinge seat that mates with the hinge frame is fixedly mounted on one end of the rotating shaft. The connecting sleeve is rotatably connected to the rotating shaft. One end of the telescopic rod is detachably connected to the connecting sleeve. The controller is fixedly mounted on the other end of the telescopic rod and is electrically connected to the laser rangefinder body.

[0006] According to one embodiment of this utility model, a locking nut is provided at the other end of the rotating shaft, and a thread that mates with the locking nut is provided on the side of the rotating shaft. An elastic pad is provided between the locking nut and the connecting sleeve, with one end of the elastic pad abutting against the locking nut and the other end of the elastic pad abutting against the connecting sleeve.

[0007] According to one embodiment of this utility model, a connector is fixedly provided on the side of the connecting sleeve, and an external thread is provided on the side of one end of the telescopic rod. A threaded hole is provided on the side of the connector to engage with the threaded connection of the telescopic rod.

[0010] The advantages of this utility model compared to the prior art are:

[0011] 1. By employing a support base, rotating shaft, connecting sleeve, and telescopic rod design, maintenance personnel no longer need to bend their bodies to enter the elevator shaft for measurement operations, thus significantly reducing safety risks. The design of the telescopic rod and rotating shaft allows the laser rangefinder to easily adapt to different measurement heights and angles, improving measurement convenience. Since maintenance personnel do not need to enter the shaft, the impact of body bending and the complex spatial layout within the shaft on measurement accuracy is greatly reduced. Simultaneously, the high-precision ranging algorithm of the laser rangefinder ensures the accuracy of the measurement results. This laser rangefinder design allows maintenance personnel to complete measurement work more quickly, reducing operational inconvenience and time waste caused by body bending and complex spatial layouts.

[0012] 2. Through the cooperation of the hinged frame and hinged base, the support base and rotating shaft of the laser rangefinder can be flexibly folded.

Detailed Implementation

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] like Figures 1 to 4 As shown, a laser rangefinder for elevator maintenance includes a laser rangefinder body 1, a support base 2, a rotating shaft 3, a connecting sleeve 4, a telescopic rod 5, and a controller 6. A display screen 7 and operation buttons 8 are provided on one side of the laser rangefinder body 1, with the operation buttons 8 located below the display screen 7. A laser emitter 9 is embedded in the center of the top of the laser rangefinder body 1. The support base 2 is detachably mounted on the other side of the laser rangefinder body 1. The rotating shaft 3 is hinged to the bottom of the support base 2. Specifically, a hinge frame 10 is fixedly mounted on the bottom of the support base 2, and a hinge seat 11 that mates with the hinge frame 10 is fixedly mounted on one end of the rotating shaft 3. The connecting sleeve 4 is rotatably connected to the rotating shaft 3. One end of the telescopic rod 5 is detachably connected to the connecting sleeve 4. The controller 6 is fixedly mounted on the other end of the telescopic rod 5 and is electrically connected to the laser rangefinder body 1.

[0023] When maintenance personnel need to extend the laser rangefinder body 1 into the elevator shaft for measurement operations, they can adjust the angle of the laser rangefinder body 1 by rotating the connecting sleeve 4 and the rotating shaft 3, so that it can accurately point to the target position inside the elevator shaft. The design of the telescopic rod 5 allows maintenance personnel to change the position of the laser rangefinder body 1 by adjusting the length of the telescopic rod 5 without entering the shaft, thereby adapting to different measurement heights.

[0024] Once the laser rangefinder body 1 is correctly positioned, maintenance personnel can activate the laser emitter 9 via the controller 6. The laser beam emitted by the laser emitter 9 will illuminate the target location and be reflected back to be received by the laser rangefinder body 1. Using the built-in ranging algorithm, the laser rangefinder body 1 can calculate the distance between itself and the target location and display the result on the display screen 7.

[0025] Maintenance personnel can view, record, and analyze the measurement results on the display screen 7 by pressing button 8. If necessary, they can also transmit the measurement results to a computer or other devices via controller 6 for further processing and reporting.

[0026] By employing the design of support base 2, rotating shaft 3, connecting sleeve 4, and telescopic rod 5, maintenance personnel no longer need to bend their bodies to enter the elevator shaft for measurement operations, thus greatly reducing safety risks. The design of telescopic rod 5 and rotating shaft 3 allows the laser rangefinder body 1 to easily adapt to different measurement heights and angles, improving the convenience of measurement. Since maintenance personnel do not need to enter the shaft, the impact of body bending and the complex spatial layout within the shaft on measurement accuracy is greatly reduced. At the same time, the high-precision ranging algorithm of the laser rangefinder body 1 also ensures the accuracy of the measurement results. This laser rangefinder design allows maintenance personnel to complete measurement work more quickly, reducing the inconvenience and time wasted due to body bending and complex spatial layouts.

[0027] The support base 2 and rotating shaft 3 of the laser rangefinder can be flexibly folded through the cooperation of the hinge frame 10 and hinge seat 11. When not in use or needing storage, maintenance personnel can easily fold the support base 2 and rotating shaft 3 together, making the entire laser rangefinder more compact and saving a significant amount of storage space. This is especially important for elevator maintenance toolboxes or vehicles with limited space, ensuring efficient use of tools and maximizing space utilization.

[0028] In some specific embodiments, the other end of the rotating shaft 3 is provided with a locking nut 12, and the side of the rotating shaft 3 is provided with a thread that mates with the locking nut 12. An elastic pad 13 is provided between the locking nut 12 and the connecting sleeve 4, with one end of the elastic pad 13 abutting against the locking nut 12 and the other end of the elastic pad 13 abutting against the connecting sleeve 4.

[0029] When it is necessary to adjust the angle of the connecting sleeve 4 relative to the rotating shaft 3, loosen the locking nut 12, and the connecting sleeve 4 can rotate freely around the rotating shaft 3. After adjusting to the appropriate angle, tighten the locking nut 12. The elastic pad 13 is located between the locking nut 12 and the connecting sleeve 4. During the tightening process, the elastic pad 13 is compressed, and its elastic deformation generates friction to prevent the connecting sleeve 4 from rotating accidentally due to vibration or other reasons during the measurement process.

[0030] This structural design allows maintenance personnel to flexibly adjust the angle of the laser rangefinder according to the needs of different measurement locations within the elevator shaft, without having to painstakingly adjust the instrument's direction by reaching into the shaft. The elastic pad 13 ensures stability after angle adjustment, guaranteeing that the instrument angle will not easily change during the measurement process, thereby improving measurement accuracy and reducing the safety risks for maintenance personnel operating inside the shaft.

[0031] In some specific implementations, a connector 14 is fixedly provided on the side of the connecting sleeve 4, and an external thread is provided on the side of one end of the telescopic rod 5. A threaded hole is provided on the side of the connector 14 to engage with the threaded connection of the telescopic rod 5. An anti-slip sleeve 15 is fixedly provided on the side of the other end of the telescopic rod 5.

[0032] By rotating the telescopic rod 5, the connection and disconnection between the telescopic rod 5 and the connecting sleeve 4 can be achieved, and the extension length of the telescopic rod 5 can also be adjusted. An anti-slip sleeve 15 is fixed to the other end of the telescopic rod 5 for easy hand-held operation by maintenance personnel.

[0033] The adjustable length design of the telescopic rod 5 allows maintenance personnel to extend the laser rangefinder body 1 to the required measurement position from outside the elevator shaft by adjusting the length of the telescopic rod 5, avoiding the need for their bodies to enter the shaft. The detachable connection method facilitates the storage and carrying of the equipment, while the anti-slip sleeve 15 enhances the stability of handheld operation, further improving the convenience and accuracy of measurement.

[0034] In some specific embodiments, a slot 16 is provided on the side of the laser rangefinder body 1, and a locking block 17 that cooperates with the slot 16 is fixedly provided on the side of the support base 2. There are several slots 16 and locking blocks 17, and the slots 16 are arranged in a matrix on the side of the laser rangefinder body 1. The locking blocks 17 are fixedly connected to the support base 2 and cooperate with the corresponding slots 16.

[0035] When installing the support base 2, simply align the locking block 17 with the corresponding locking slot 16 and insert it to quickly connect the support base 2 to the laser rangefinder body 1. The locking slots 16 in different positions can meet the needs of adjusting the installation position of the support base 2 in different measurement scenarios.

[0036] This structure makes the installation and disassembly of the support base 2 extremely convenient. Maintenance personnel can quickly select the appropriate slot 16 position to install the support base 2 according to the actual measurement situation, and then flexibly adjust the position and angle of the laser rangefinder body 1 to improve measurement efficiency and avoid the inconvenience of maintenance personnel staying in the shaft for a long time and operating due to the cumbersome traditional installation method.

[0037] In some specific implementations, the laser rangefinder body 1 has an interface 18 on its side, and the controller 6 has a plug 19 that mates with the interface 18. A connecting line 20 is provided between the plug 19 and the controller 6, with one end of the connecting line 20 connected to the controller 6 and the other end of the connecting line 20 connected to the plug 19.

[0038] Maintenance personnel operate controller 6 outside the elevator shaft. Controller 6 transmits operation commands to laser rangefinder body 1 via connection cable 20, enabling remote control of the laser rangefinder, such as starting measurement and switching measurement modes. Measurement results are also fed back to controller 6 via connection cable 20 and displayed on display screen 7 of laser rangefinder body 1.

[0039] The remote control function allows maintenance personnel to complete measurement operations from a safe area outside the wellbore without having to approach the laser rangefinder body 1, avoiding dangerous actions such as probing into the wellbore. At the same time, this connection method ensures the stability of data transmission, guaranteeing that measurement results can be accurately and promptly fed back to maintenance personnel, thus improving the safety and efficiency of maintenance work.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
