[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] This utility model provides a device for detecting the distance between an elevator door and a lane, such as... Figure 1-4 As shown, the elevator door-to-alley distance detection device includes: a mounting box 1, which houses a distance tester 2 for detecting the distance between the elevator door and the alley; a removable cover plate 3 at the bottom of the mounting box 1; lifting rings 4 symmetrically fixedly mounted on the distance tester 2, each with a removable hook 5; a mounting base 6 symmetrically fixedly mounted inside the mounting box 1, on which a winding roller 7 is rotatably mounted, and on which a retractable steel wire rope 8 is mounted; a hanger 9 fixedly mounted on the bottom end of the steel wire rope 8, on which symmetrically fixed hanging ropes 10 are mounted, the bottom end of which is fixedly connected to the hook 5; a mounting frame 12 fixedly mounted on the mounting box 1, on which a motor 11 is fixedly mounted, the output shaft of which is fixedly connected to the winding roller 7 via a coupling; and a support mechanism on the mounting box 1 for supporting and limiting movement.
[0022] In this embodiment, the distance tester 2 (TEJJ-2 model from Dalian Leite Optoelectronic Precision Instrument Co., Ltd.) scans the inner wall of the shaft by emitting laser or light, collecting a large amount of point cloud data. Then, professional software is used to stitch the point cloud data into a three-dimensional model, which can intuitively view the overall distance between the elevator door and the shaft, and is suitable for shaft inspection of complex structures. Compared with traditional tape measure measurement, this advanced detection method greatly improves the accuracy and efficiency of the inspection, avoids the interference of human factors on the data, and can comprehensively obtain detailed information on the distance between the elevator door and the shaft, providing more accurate data support for elevator safety assessment. The detachable cover plate 3 is set at the bottom of the mounting box 1. The cover plate 3 can be removed during inspection. The lifting ring 4 and the detachable hook 5, which are symmetrically fixed on the distance tester 2, together with the winding roller 7, the retractable steel wire rope 8, the bottom fixed hanger 9 and the lifting rope 10, which are fixedly installed on the mounting base 6 in the mounting box 1, form a lifting and adjustment system. The motor 11 is fixedly mounted on the mounting bracket 12, and its output shaft is fixedly connected to the winding roller 7 via a coupling. When the motor 11 rotates, it drives the winding roller 7 to rotate, thereby realizing the winding and unwinding of the wire rope 8, and thus adjusting the height of the hanger 9, which in turn realizes the lifting and lowering adjustment of the distance tester 2. This design effectively solves the problem of poor adaptability and insufficient operational convenience caused by the lack of flexible lifting and lowering adjustment function in existing detection devices when facing the task of detecting the distance between elevator doors and shafts at different heights. The inspection personnel can conveniently control the motor 11 according to the actual height of the elevator shaft, and accurately raise and lower the distance tester 2 to the required measurement position. Whether it is a high or low position for distance detection, it can be easily handled, which greatly improves the efficiency and safety of the inspection work and reduces the difficulty and danger of high-altitude measurement operations. Meanwhile, the detachable design of the lifting ring 4 and hook 5 facilitates the individual disassembly and installation of the distance tester 2 when needed, making transportation and storage convenient and further improving the practicality and flexibility of the entire testing device. The support mechanism, located on the mounting box 1, provides support and limits the mounting box 1 during the testing process, ensuring the stability of the entire testing device during operation. In the complex environment of elevator shafts, stable support is a crucial prerequisite for ensuring the accuracy of testing data. The support mechanism prevents the mounting box 1 from shaking or shifting during testing, thereby ensuring that the distance tester 2 can stably and accurately measure the distance between the elevator door and the shaft, further improving the reliability of the testing results.
[0023] In a further preferred embodiment of the present invention, the support mechanism includes: a mounting shell 13 symmetrically fixedly mounted on the mounting box 1; an electric telescopic rod 14 fixedly mounted inside the mounting shell 13 for adjusting the spacing; and a bracket 15 fixedly mounted on the output rod of the electric telescopic rod 14, wherein a positioning plate 16 is fixedly mounted on the bottom of the bracket 15.
[0024] In this embodiment, the mounting shell 13 is symmetrically fixedly installed on the mounting box 1, providing a stable mounting base and protective shell for the electric telescopic rod 14. Its fixed position within the mounting box 1 ensures a tight fit between the entire support mechanism and other parts of the detection device. Furthermore, it maintains structural integrity and stability during movement and operation within the elevator shaft, preventing damage to the internal electric telescopic rod 14 due to external factors such as collisions, thus guaranteeing the reliability and durability of the support mechanism. The electric telescopic rod 14, fixedly installed within the mounting shell 13, plays a crucial role as a key component for adjusting the spacing. In different elevator shaft environments, the spacing between walls may vary. Through the telescopic function of the electric telescopic rod 14, the positions of the bracket 15 and the positioning plate 16 can be precisely adjusted to adapt to various shaft widths, ensuring close contact with the shaft walls and providing stable and reliable support for the mounting box 1. Compared to traditional fixed support structures, this adjustable design greatly enhances the versatility and adaptability of the testing device. Whether facing narrow or wide wells, it can quickly adjust to a suitable support state, improving the efficiency and flexibility of the testing work. One end of the bracket 15 is fixed to the output rod of the electric telescopic rod 14, and the other end has a positioning plate 16 fixedly installed at its bottom. After the electric telescopic rod 14 is adjusted to the correct spacing, the bracket 15 firmly supports the positioning plate 16 against the well wall. The surface of the positioning plate 16 in contact with the well wall can employ a special anti-slip design, such as adding rubber pads, to further enhance friction and prevent displacement of the mounting box 1 due to device vibration or other factors during testing. This stable support structure ensures that the distance tester 2 maintains a fixed position and posture during measurement, avoiding measurement errors caused by shaking, thereby improving the accuracy and reliability of the testing data.
[0025] In a further preferred embodiment of this utility model, hooks 18 are symmetrically fixedly installed on the cover plate 3, and buckles 19 are symmetrically fixedly installed on the mounting box 1, with the buckles 19 engaging with the corresponding hooks 18.
[0026] In this embodiment, the hooks 18 symmetrically fixedly installed on the cover plate 3 and the buckles 19 symmetrically fixedly installed on the mounting box 1 that engage with the hooks 18 constitute a simple and effective connection structure that can limit the position of the cover plate 3.
[0027] In a further preferred embodiment of the present invention, the mounting plate 20 fixedly installed in the mounting box 1 has a ring 21 fixedly installed on the mounting plate 20 for limiting and guiding the wire rope 8.
[0028] In this embodiment, the mounting plate 20 is fixedly installed inside the mounting box 1, providing a stable mounting base and support structure for the ring 21. It ensures that the ring 21 is fixed and reliable inside the mounting box 1, allowing it to accurately perform its guiding and limiting function on the wire rope 8. Even when the detection device moves or experiences a certain degree of vibration, the mounting plate 20 ensures that the position of the ring 21 remains stable, thereby maintaining the stability and reliability of the entire lifting and adjusting system and providing strong support for the precise lifting and lowering of the distance tester 2.
[0029] In a further preferred embodiment of this utility model, the mounting plate 20 is provided with a rope hole, which is adapted to the steel wire rope 8.
[0030] In this embodiment, the rope hole can play a certain role in constraining and positioning the wire rope 8, further ensuring that the wire rope 8 performs precise winding and unwinding movements along a predetermined trajectory under the guidance of the ring 21.
[0031] In a further preferred embodiment of the present invention, mounting blocks are symmetrically fixed on the top of the mounting box 1, and handles 17 for gripping and lifting are hinged on the mounting blocks.
[0032] In this embodiment, the symmetrically fixed mounting blocks on the top of the mounting box 1 provide a stable connection point for the handle 17. The handle 17 is hinged to the mounting blocks, a design that offers several advantages. In practical use of the elevator door and shaft spacing detection device, inspectors often need to move the device between different elevator shafts. The handle 17 provides inspectors with a convenient gripping and lifting point, making the handling process easier and more convenient.
[0033] In a further preferred embodiment of this utility model, an inspection door is connected to the mounting box 1 via a hinge, and a door lock is provided on the inspection door.
[0034] In this embodiment, the maintenance door on the mounting box 1, connected by a hinge, provides a convenient maintenance passage for inspection personnel. Since the elevator door and aisle distance detection device contains precision components such as the distance tester 2, it may require adjustments, maintenance, or component replacement during long-term use. These operations can be performed simply by opening the box door.
[0035] In summary, by using the distance measuring instrument 2 for detection, the accuracy and efficiency of detecting the distance between the elevator door and the shaft are improved, human interference is avoided, and precise data support is provided for elevator safety assessment, solving the drawbacks of the traditional tape measure method. The lifting and adjustment system, composed of the lifting ring 4, hook 5, mounting base 6, winding roller 7, wire rope 8, hanger 9, lifting rope 10, and motor 11, enables flexible lifting and lowering of the distance measuring instrument 2, effectively handling detection tasks at different heights, improving the adaptability, ease of operation, practicality, and flexibility of the detection device, and reducing the difficulty and danger of high-altitude measurement operations. The mounting shell 13, electric telescopic rod 14, bracket 15, and positioning plate 16 in the support mechanism ensure the stability of the detection device during operation, adapt to different shaft widths, enhance the versatility and reliability of the detection device, and guarantee the accuracy of the detection data.
