Abstract
Description
Technical Field
[0001] The invention relates to the field of safety engineering and protection technology, in particular to an escalator brush mechanism with a safety warning component. Background Art
[0002] The brush mechanism for escalators is a safety protection device installed in the gap between the skirt and the steps on both sides of the escalator. It is mainly composed of elastic bristles and a base. Its core function is to provide tactile warnings when passengers come into contact with the brush mechanism through densely arranged wear-resistant bristles (usually made of nylon or polyurethane), preventing feet, clothing or small objects from being caught in dangerous gaps (international standards require gaps of no more than 4 to 6 mm), thereby playing an active early warning role. It is a key component to improve the public safety of escalators.
[0003] This mechanism, typically installed at the junction of the escalator steps and the apron panels on either side, consists of rows of elastic nylon bristles. As the escalator operates, the bristles maintain slight contact with the apron panels at an angle. This physically prevents passengers' shoes, clothing, or small items from becoming caught in the gap between the steps and the apron panels. Furthermore, the reciprocating motion of the bristles removes dust and debris from the apron panels. The bristles are flexible, effectively removing foreign matter without obstructing the escalator's operation and serving as a reminder for passengers to maintain a safe standing position.
[0004] When the brush mechanism for escalators is in use, passengers get too close to the gap between the skirts and steps on both sides of the escalator. Since traditional brushes only have a physical isolation function and cannot actively warn, it is difficult for passengers to perceive potential dangers. In addition, some advanced models are also equipped with sensors. When the bristles are subjected to abnormal pressure, they will alarm through sound or flashing lights, resulting in the problem of dangers being ignored in noisy or brightly lit environments, and thus losing the function of actively providing alarms.

[0014] Beneficial effects The escalator brush mechanism with a safety warning component provided by the present invention has the following beneficial effects: 1. Through the coordinated use of the human contact plate and the protective plate, the handrail can give a lateral thrust to the fixed circular frame through the passenger's feet, thereby pushing the protective plate to swing inside the outer frame. Different protection measures and alarm measures are taken according to the degree of this swing, thus achieving graded safety protection. Light or medium pressure provides a warning, and excessive contact immediately takes protective measures. This not only protects passengers, but also reduces the false alarm rate caused by the complex external environment through graded protection.
[0015] 2. Through the coordinated use of the sliding bottom frame and the contact block, when the passenger's foot contacts the gap between the skirt and the step during the operation of the escalator, the side slide plate drives the telescopic rod to separate from the inside of the outer frame and then contact the passenger's foot. The thrust given by the power shaft to the push block interacts with the thrust given by the rebound paddle, thereby driving the striking hammer to swing back and forth and then strike the surface of the human body contact plate, thereby generating vibration and transmitting it to the passenger's foot through the human body contact plate, thereby alerting the passenger. By automatically extending the contact plate to directly contact the human body and synchronously triggering the vibration prompt, the dual warning effects of tactile and physical feedback are realized. In addition, the structure is simple and the anti-interference ability is strong. It can still work stably in complex environments, further enhancing the overall safety of the escalator.
[0016] 3. Through the coordinated use of the contact block and the protective plate, when the passenger's feet excessively contact the gap between the skirt board and the step, the sliding bottom frame continues to slide toward the contact block under the drive of the swing base until the swing base swings to the maximum angle. At this time, the retracting slide bar loses the restriction of the release slider, and the retracting slide bar slides downward under the action of the spring, thereby driving the protective plate to slide downward, thereby temporarily blocking the gap between the skirt board and the step. Its threshold trigger mechanism is set through a precise mechanical structure to ensure that the baffle will only be activated when a substantial danger such as a continuous large external force is detected. It can effectively avoid operation interruption caused by false triggering, and can filter out non-dangerous minor contacts through delayed response, thereby improving the reliability of the device.

When the passenger's feet are in excessive contact with the gap between the skirt and the steps during the operation of the escalator, the fixed circular frame 412 on the surface of the protective plate 411 comes into contact with the passenger's feet, thereby giving the fixed circular frame 412 a lateral thrust through the passenger's feet, thereby pushing the protective plate 411 to swing inside the outer frame 1, as shown in FIG. Figure 4 In the embodiment, the rotating push block 314 is slidably connected to the inside of the sliding bottom frame 313, the contact block 315 is arranged inside the outer frame 1, the contact block 315 is located inside the sliding path of the sliding bottom frame 313, and the contact block 315 is provided with an inclined surface on the side close to the sliding bottom frame 313. The swing base 311 and the sliding bottom frame 313 are provided with multiple, and the multiple sliding bottom frames 313 are connected to each other. The rotating push block 314 gives the sliding bottom frame 313 a thrust in the direction of the contact block 315, and then pushes the contact block 315 to slide downward through the inclined surface on the surface of the contact block 315.
[0022] like Figure 4In the embodiment, an extension groove 316 is provided on the surface of the contact block 315 near the side of the sliding bottom frame 313, and a side slide 318 is slidably connected to the interior of the outer frame 1. A contact shaft 317 is provided on one side of the side slide 318, and the contact shaft 317 is slidably connected to the interior of the extension groove 316. A human body contact plate 3111 is provided inside the outer frame 1, and a telescopic rod 319 and a No. 1 spring 3110 are provided between the human body contact plate 3111 and the side slide 318. When the contact block 315 slides downward, the thrust of the inner wall of the surface extension groove 316 drives the contact shaft 317 to slide in the direction away from the interior of the outer frame 1, and then drives the telescopic rod 319 to separate from the interior of the outer frame 1 through the side slide 318 and then contact the passenger's foot. like Figure 5 and Figure 6 In the embodiment, a fixed inner frame 3112 is provided on the side of the human body contact plate 3111 close to the sliding bottom frame 313, a fixed side frame 3114 is provided on the surface of the fixed inner frame 3112, a torsion spring 3115 is provided inside the fixed side frame 3114, a power gear 3113 is provided on one side of the fixed side frame 3114, a central axis is provided on the side of the power gear 3113 close to the fixed side frame 3114, the central axis passes through the inner cavity of the fixed side frame 3114 and is rotatably connected to the surface of the fixed inner frame 3112, and the central axis is fixedly connected to one end of the torsion spring 3115, the power shaft 3119 and the knocking hammer 3116 are both provided on the inner wall of the fixed inner frame 3112, and the knocking hammer 3116 is close to the power shaft A push block 3118 is provided on one side of the shaft 3119. When the human body contact plate 3111 slides outward, the power gear 3113 contacts the internal gear block of the outer frame 1, and the power gear 3113 rotates, driving the torsion spring 3115 to tighten inside the fixed side frame 3114. After the human body contact plate 3111 contacts the passenger's foot, the power gear 3113 no longer contacts the gear block on the inner wall of 1. The power gear 3113 loses the restriction of the gear block and rotates under the rebound action of the torsion spring 3115. The power gear 3113 drives the crawler track inside the transmission assembly to drive the transmission shaft fixed to the power shaft 3119 to rotate, thereby driving the power shaft 3119 to rotate. The inner wall of the fixed inner frame 3112 is provided with a rebound pick 3117, and the rebound pick 3117 is located inside the rotation path of the striking hammer 3116. A tooth block is provided on the lower inner wall of the outer frame 1. The power gear 3113 is engaged with the tooth block on the inner wall of the outer frame 1. A transmission component is provided between the power shaft 3119 and the power gear 3113. Two contact blocks are provided on the surface of the power shaft 3119. Both ends of the push block 3118 are provided with inclined surfaces. The power shaft 3119 is located on the center line of the inclined surfaces at both ends of the push block 3118. Whether the power shaft 3119 rotates clockwise or counterclockwise, it can be driven by the power The contact block on the surface of the rotating shaft 3119 squeezes the inclined surface of the pushing block 3118, thereby giving the inclined surface of the pushing block 3118 a thrust away from the human body contact plate 3111, driving the pushing hammer 3116 to swing toward the rebound pick 3117, and then the thrust given to the pushing block 3118 by the power rotating shaft 3119 interacts with the thrust given by the rebound pick 3117, thereby driving the striking hammer 3116 to swing back and forth and then strike the surface of the human body contact plate 3111, thereby generating vibration and transmitting it to the passenger's feet through the human body contact plate 3111, thereby alerting the passenger.
[0023] like Figure 7 In the embodiment, a fixed circular frame 412 is provided on the lower surface of the contact block 315, a retractable slide bar 413 is provided inside the fixed circular frame 412, and a blocking block 414 is provided on the surface of the retractable slide bar 413. When the passenger's foot contacts the hard brush 312, the swing base 311 swings, and a release slider 415 is provided inside the outer frame 1. The release slider 415 is U-shaped. When the swing base 311 approaches the inclined surface of the contact block 315, the swing base 311 squeezes the contact block 315, causing the contact block 315 to slide downward, and the contact block 315 drives the fixed circular frame 412 to slide downward. Since the blocking block 414 is located inside the sliding path of the release slider 415, the retractable slide bar 413 cannot slide downward. At this time, the retractable slide bar 413 is retracted to the inside of the fixed circular frame 412. The end of the release slider 415 close to the positioning block 414 is located inside the sliding path of the positioning block 414, and the end of the release slider 415 away from the positioning block 414 is located inside the sliding path of the sliding bottom frame 313. The protective plate 411 is provided at the bottom end of the retractable slide bar 413. The length of the single outer frame 1 is short. The protective plate 411 blocks the gap between the skirt board and the step under the single outer frame 1. The entire gap between the skirt board and the step is blocked by a combination of multiple protective plates 411. The end of the positioning block 414 close to the fixed circular frame 412 is provided with an inclined surface. A spring is provided between the fixed circular frame 412 and the retractable slide bar 413. When the passenger's feet are in excessive contact with the gap between the skirt board and the step, The sliding bottom frame 313 continues to slide toward the contact block 315 under the drive of the swing base 311 until the swing base 311 swings to the maximum angle. At this time, the sliding bottom frame 313 contacts one end of the release slider 415. The release slider 415 slides in the direction away from the contact block 315 under the drive of the sliding bottom frame 313, thereby driving one end of the release slider 415 to disengage from the sliding path of the locking block 414. At this time, the retracting slide bar 413 loses the restriction of the release slider 415, and the retracting slide bar 413 slides downward under the action of the spring, thereby driving the protective plate 411 to slide downward, thereby temporarily blocking the gap between the skirt board and the step.
[0024] The effects achieved by this embodiment are as follows: The following is the entire working process and working principle of the above embodiment: During the operation of the escalator, when the passenger's foot contacts excessively with the gap between the skirt and the step, the hard brush 312 on the surface of the swing base 311 contacts the passenger's foot, thereby giving the hard brush 312 a lateral thrust through the passenger's foot, thereby pushing the swing base 311 to swing inside the outer frame 1, thereby giving the sliding bottom frame 313 a thrust toward the contact block 315 through the rotating push block 314 connected to one end of the swing base 311, and then pushing the contact block 315 downward through the inclined surface of the contact block 315. During the downward sliding process of the contact block 315, the thrust of the inner wall of the surface extension groove 316 drives the contact shaft 317 to slide in the direction away from the inside of the outer frame 1, and then drives the human body contact plate 3111 to leave the inside of the outer frame 1 through the side slide plate 318 and the telescopic rod 319 and then contact the passenger's foot.
[0025] At the same time, as the human body contact plate 3111 slides outward, the power gear 3113 contacts the internal gear block of the outer frame 1, the power gear 3113 rotates, and drives the torsion spring 3115 to tighten inside the fixed side frame 3114, until the human body contact plate 3111 contacts the passenger's foot and the power gear 3113 is separated from the inside of the outer frame 1, the power gear 3113 loses the restriction of the gear block, and rotates under the rebound action of the torsion spring 3115, thereby driving the power shaft 3119 to rotate through the transmission assembly, and then the power shaft 3119 gives the thrust to the push block 3118 and the rebound pick 3 The thrust given by 117 interacts with each other, thereby driving the striking hammer 3116 to swing back and forth and then strike the surface of the human body contact plate 3111, thereby generating vibration and transmitting it to the passenger's feet through the human body contact plate 3111, thereby alarming the passenger. The escalator brush mechanism can automatically extend the contact plate to directly contact the human body when the passenger is too close to the dangerous area between the skirt panels on both sides and the steps, and simultaneously trigger a vibration prompt, thereby achieving a dual warning effect of tactile and physical feedback, and has a simple structure and strong anti-interference ability, and can still work stably in complex environments, further enhancing the overall safety of the escalator.
[0026] When the passenger's foot contacts the hard brush 312, the swing base 311 swings, and the contact block 315 slides downward, which in turn drives the fixed circular frame 412 to slide downward. Since the locking block 414 is located within the sliding path of the release slider 415, the retractable slide bar 413 cannot slide downward. At this time, the retractable slide bar 413 retracts into the inside of the fixed circular frame 412. When the passenger's foot contacts the gap between the skirt and the step excessively, the sliding bottom frame 313 continues to slide towards the contact block 315 under the drive of the swing base 311 until the swing base 311 swings to the maximum angle. At this time, the sliding bottom frame 313 contacts one end of the release slider 415, and the release slider 415 slides in the direction away from the contact block 315 under the drive of the sliding bottom frame 313, thereby driving one end of the release slider 415 to disengage from the sliding path of the locking block 414. At this time, the retracting slide bar 413 loses the restriction of the release slider 415, and the retracting slide bar 413 slides downward under the action of the spring, thereby driving the protective plate 411 to slide downward, thereby temporarily blocking the gap between the skirt and the step. Its threshold trigger mechanism is set by a precise mechanical structure to ensure that the baffle will be activated only when a substantial danger such as a continuous large external force is detected. It can not only effectively avoid operation interruption caused by false triggering, but also filter out non-dangerous minor contacts through delayed response.
[0027] When the baffle finally pops out, its characteristic of quickly physically closing the gap can directly block the occurrence of pinching accidents, providing more active protection than a pure early warning system. The entire process is completely completed independently by the mechanical mechanism, does not rely on electricity or sensors, and still maintains ultra-high reliability in complex environments. Through the coordinated use of the human body contact plate 3111 and the protection plate 411, when the passenger's feet are in excessive contact with the gap between the skirt and the steps during the operation of the escalator, the hard brush 312 on the surface of the swing base 311 comes into contact with the passenger's feet, thereby giving the hard brush 312 a lateral thrust through the passenger's feet, thereby pushing the swing base 311 to swing inside the outer frame 1, and different protection measures and alarm measures are made according to the degree of this swing, thereby realizing graded safety protection, providing warnings with slight or medium pressure, and taking immediate protective measures in case of excessive contact, which not only protects passengers but also reduces the false alarm rate caused by the complex external environment through graded protection.
[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
