Description

Technical Field

[0001] The utility model relates to the technical field of escalators, in particular to an escalator and a sidewalk ladder locking device. Background Art

[0002] The lighting system of the escalator glass handrail is a design element that combines beauty, practicality and safety. The glass handrail combined with the lighting system makes the overall appearance of the escalator more modern and fashionable, and improves the overall visual effect of public places such as shopping malls and subway stations. The lighting system provides passengers with better visual guidance, especially in a dimly lit environment, so that passengers can see the edge of the handrail more clearly, increasing the convenience of use. The lighting system can remind passengers to pay attention to the edge of the handrail and reduce the risk of falling due to misjudgment. At the same time, through reasonable light distribution and color selection, it can avoid interference or discomfort to the passenger's vision.

[0003] Most traditional escalator and pedestrian ladder locking devices are in the form of a whole LED light strip, which is installed on the outside of the glass railing, below the handrail bracket, and arranged along the handrail running path. This type of escalator and pedestrian ladder locking device has shortcomings when used. If a section of the LED light strip fails to light up, the entire LED light strip needs to be removed for maintenance or replacement, which is inconvenient and costly to maintain. Therefore, it is necessary to optimize and improve the traditional escalator and pedestrian ladder locking device. Utility Model Content

[0027] In this embodiment, the first mounting plate 1 is provided with a first clamping member 101 for clamping it to the outside of the first truss 11, and a guide plate 102 with guide holes is installed on the outside of the first clamping member 101. At least two bolts 3 are installed in parallel on the first mounting plate 1;

[0028] In this embodiment, the second mounting plate 7 is provided with a second clamping piece 701 for clamping it to the outer side of the second truss 12. The second mounting plate 7 is provided with a locking groove 702 and an unlocking groove 703. The locking groove 702 and the unlocking groove 703 are arranged in parallel, and the locking groove 702 is located between the toothed sprocket 10 and the unlocking groove 703.

[0029] In this embodiment, a strip sliding groove is provided on the sliding lock ladder frame plate 2 for the bolt 3 to pass through. A cylindrical stop iron 10 is installed at one end of the sliding lock ladder frame plate 2 close to the toothed sprocket 10. The cylindrical stop iron 10 can be inserted into the tooth groove of the toothed sprocket 10 to prevent it from rotating, thereby achieving the effect of locking the ladder.

[0030] One end of the push-pull rod 5 passes through the web of the sliding lock ladder frame plate 2, and an anti-drop nut 501 is installed on the end. A spring 6 is sleeved on the outer side of the push-pull rod 5, and a stop nut 502 for limiting the spring 6 is installed on the push-pull rod 5. The push-pull rod 5 passes through the guide through hole of the guide plate 102, and the other end of the push-pull rod 5 is provided with a bent lock rod 503 that is easy to be inserted into the locking groove 702 or the unlocking groove 703.

[0031] In this embodiment, a switch striking plate 8 for switching the state of the limit switch 9 is installed near the push-pull rod 5 and the bent locking rod 503 .

[0032] In this embodiment, the sliding lock ladder frame plate 2 is a groove frame plate, and the web of the groove frame plate is provided with a sliding hole for the push-pull rod 5 to pass through. The two side plates of the groove frame plate are symmetrically provided with multiple sets of parallel strip sliding grooves, the screw diameter value of the bolt 3 and the groove width value of the strip sliding groove are matched with each other, and a movable gap is left between the end of the bolt 3 and the side plate of the sliding lock ladder frame plate 2 to facilitate the smooth sliding of the groove frame plate.

[0033] In this embodiment, a mark for distinguishing the locking groove 702 and the unlocking groove 703 is provided on the second mounting plate 7 .

[0034] A specific application of this embodiment is: when unlocking, pull out the push-pull rod 5, drive the sliding lock ladder frame plate 2 to retreat, away from the toothed sprocket 10, and the bent lock rod 503 of the push-pull rod 5 needs to be screwed into the unlocking groove 703 of the second mounting plate 7 to ensure that the device is always in the unlocked state. When it is necessary to lock the ladder, the bent lock rod 503 of the push-pull rod 5 is screwed out from the unlocking groove 703 of the second mounting plate 7, and pushed forward to drive the sliding lock ladder frame plate 2 forward, and the cylindrical stop iron 4 in the sliding lock ladder frame plate 2 is stuck in the tooth groove of the toothed sprocket 10 to prevent it from rotating, so as to achieve the effect of locking the ladder. At this time, the spring 6 is in a compressed state, and continuously applies a pressing force to the sliding lock ladder frame plate 2 to ensure the reliability of locking the ladder. Finally, rotate the push-pull rod 5, and its bent lock rod 503 is stuck in the locking groove 702 of the second mounting plate 7 to ensure that the device is always in the locked state. The second mounting plate 7 is provided with a text mark, which is clear and concise. In addition, a limit switch 9 is provided. When the push-pull rod 5 is pushed into the locked state, the limit switch 9 is contacted by the switch striking plate 8 and actuated, cutting off the safety circuit and making the escalator device unable to start. When the push-pull rod 5 is pulled into the unlocked state, the switch striking plate 8 is away from the limit switch 9, the switch is closed, the safety circuit is connected, and the escalator device is allowed to start. In this way, safety is guaranteed from the electrical control aspect.
