Description

Technical Field

[0001] This utility model relates to the field of photoelectric sensing technology, and in particular to a novel step-missing photoelectric support. Background Technology

[0002] The novel step-missing photoelectric bracket is a safety monitoring device for escalators. Designed for installation on the side of the escalator truss, it uses photoelectric sensing technology to detect metal reflection signals on the step rollers, thus enabling real-time monitoring of missing steps. When a missing step is detected, the device immediately issues an alarm and triggers the escalator stop mechanism to ensure passenger safety. The bracket's quick-release structure and side-mounting design allow for convenient installation and debugging without disassembling the steps, significantly improving maintenance efficiency.

[0003] In existing escalators, photoelectric sensor switches are typically installed inside the escalator's internal structure. This installation method requires maintenance personnel to enter the escalator to operate the switches, either for debugging or replacement. Specifically, maintenance personnel must first disassemble the escalator steps to access the photoelectric sensor switch for debugging or replacement. After debugging or replacement, the steps are reinstalled to ensure the escalator functions properly. This process is not only time-consuming and labor-intensive but also increases the complexity and risk of maintenance work.

[0004] Existing technologies require disassembling and reinstalling the steps every time the photoelectric sensor switch is debugged or replaced. This not only increases maintenance workload but may also prolong maintenance time, affecting the normal operation of the escalator. Because operations require access to the escalator interior, maintenance personnel need to spend more time and effort, reducing maintenance efficiency and increasing costs. Furthermore, the limited space inside the escalator may restrict personnel's operations, making debugging and replacement even more difficult. Therefore, a novel photoelectric sensor bracket for missing steps is proposed to solve these problems. Utility Model Content

The insert 5010 can automatically reset and maintain its engagement with the slot 502. A limiting plate 5011 is fixedly connected to the surface of the insert 5010 to limit the movement direction of the insert 5010. The outer wall of the limiting plate 5011 is slidably connected to the inner wall of the movable groove 508. One side of the insert 5010 is elastically connected to the inner wall of the movable groove 508 through a spring A505. The other side of the insert 5010 abuts against the inner wall of the slot 502. An adjustment structure 6 is provided on the back plate 2 to adjust the position of the photoelectric sensor switch 3. A support plate 7 is fixedly connected to the back of the back plate 2 to provide an installation base for the photoelectric sensor switch 3. The bottom of the photoelectric sensor switch 3 contacts the top of the support plate 7.

[0032] Reference Figure 3 , Figure 6 The adjustment structure 6 includes a protective shell 601 to protect internal parts from external interference. The back of the protective shell 601 is fixedly connected to the front of the back plate 2. A bidirectional thread 602 is threaded through the inner side of the protective shell 601, allowing the slider 605 to move by rotation. One end of the bidirectional threaded rod 602 is rotatably connected to the inner wall of the protective shell 601 via a bearing, and the other end of the bidirectional threaded rod 602 is fixedly connected to a knob 603 for manual operation. The surface of the bidirectional threaded rod 602 is threaded with a slider 605, which drives the adjustment plate 4 to move and adjust the position of the photoelectric sensor switch 3. A strip-shaped hole is provided on the back of the back plate 2, and the top and bottom of the slider 605 are connected to the back of the back plate 2. The slider 605 is slidably connected to the inner wall of the strip-shaped sliding hole 604, which restricts the movement direction of the slider 605. An adjustment plate 4 is fixedly connected to the back of the slider 605, which directly contacts and supports the photoelectric sensor switch 3. The inner side of the adjustment plate 4 contacts the two sides of the photoelectric sensor switch 3 respectively. A limit groove 606 is opened on the back of the back plate 2 to restrict the movement direction of the adjustment plate 4. A limit block 607 is provided on the inner wall of the limit groove 606, which cooperates with the limit groove 606 to ensure the stable movement of the adjustment plate 4. The back of the limit block 607 is fixedly connected to the front of the adjustment plate 4. Both the limit block 607 and the limit groove 606 are "T" shaped. The outer wall of the limit block 607 is slidably connected to the inner wall of the limit groove 606.

[0033] Working principle: Align the back plate 2 with the rectangular opening 501 on the truss 1, so that the back of the back plate 2 contacts the front of the truss 1. The rubber pad acts as a buffer and seal. Press down the pinch plate 504. The pinch plate 504 moves inward due to the elastic action of the spring B509, which simultaneously drives the pull rope 506 to pull the insert block 5010, causing the insert block 5010 to exit from the slot 502. Push the back plate 2 into the rectangular opening 501, so that the insert block 5010 is aligned with the slot 502. Release the pinch plate 504. The elastic action of the spring A505 causes the insert block 5010 to automatically insert into the slot 502, completing the fixed connection between the back plate 2 and the truss 1.

[0034] Then, place the photoelectric sensor switch 3 on the support plate 7, ensuring that its bottom is in contact with the top of the support plate 7. Rotate the knob 603, which drives the bidirectional threaded rod 602 to rotate. The rotation of the bidirectional threaded rod 602 causes the slider 605 to move along the strip-shaped sliding hole 604. The slider 605 drives the adjusting plate 4 to move. The movement of the adjusting plate 4 is ensured to move in a straight line through the cooperation of the limiting block 607 and the limiting groove 606, thereby adjusting the position of the photoelectric sensor switch 3 so that it can accurately sense the missing step.

[0035] When the ladder is running normally, the photoelectric sensor switch 3 detects the signal of the ladder, and the equipment works normally. If a ladder is missing, the photoelectric sensor switch 3 will not be able to detect the signal and will issue an alarm signal to remind the staff to deal with it in time. During disassembly, simply press the pinch plate 504. The pinch plate 504 pulls the insert block 5010 through the pull rope 506, causing the insert block 5010 to exit from the slot 502. Then, pull the back plate 2 out of the rectangular opening 501 to complete the disassembly of the back plate 2 from the truss 1. Finally, remove the photoelectric sensor switch 3 for maintenance or replacement. After completion, repeat the above installation steps to reinstall.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
