Description

Technical Field

[0001] This utility model relates to the field of security equipment technology, specifically to an escalator stop alarm device. Background Technology

[0002] An escalator is a mechanical device that continuously transports people, consisting of steps, handrails, and a drive mechanism. It is widely used in densely populated places such as shopping malls, train stations, and airports, achieving vertical or inclined transport of people through the cyclical movement of the steps. During operation, the handrails move synchronously with the steps, providing support for passengers. Its smooth transport characteristics bring convenience to people's travel and make it a common auxiliary device in modern public transportation and commercial facilities.

[0003] Utility model patent CN222934989U discloses an escalator, which includes a support base, steps, handrails, glass, limiting pads, a first cleaning component, a second cleaning component, and a fixing component. This utility model adds limiting pads to existing escalators. The rear side of the limiting pads is on the same plane as the rear side of the steps, and the color of the limiting pads is different from the color of the steps, making it easy to distinguish the steps and allowing customers to easily see the safety area between the two limiting pads. At the same time, the limiting pads provide protection for customers, preventing them from stepping into gaps when moving backward. This solves the problem that existing escalators often lack clear distinction at the step boundaries and have no protective components, leading to accidents where customers still step on the wrong step.

[0004] The escalator does not have a stop alarm structure. If an additional stop alarm device is to be installed, it must be installed by fixing it with anchor holes, bolts, etc. The installation process requires tools and is difficult to adjust flexibly according to actual needs, resulting in insufficient portability. Therefore, we propose an escalator stop alarm device. Utility Model Content

[0005] The purpose of this invention is to provide an escalator stop alarm device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An escalator stop alarm device includes an escalator side that makes up the escalator. An alarm mechanism is installed on the escalator side. The alarm mechanism includes a mounting arm assembly that is attached to the escalator side and a sensing component installed on the mounting arm assembly. The mounting arm assembly includes a sleeve rod and a suction cup that is attached to the side surface of the escalator side. The tail end of the suction cup has a protruding tube that passes through the top of the sleeve rod. The sensing component includes a base located below the sleeve rod and a roller rotatably connected to the base. The outer circumferential surface of the roller abuts against the handrail surface of the escalator side. A sleeve is provided at the top of the base. The sleeve is fitted inside the sleeve rod and slidably connected to the sleeve rod. A speed sensor is installed on the outer end face of the base for detecting the rotational speed of the roller. A seat plate is provided at the outer end of the base, and an alarm is installed at the top of the seat plate.

[0008] Preferably, one side of the escalator includes a base, a handrail, and a support, the support being made of tempered glass and having a track installed on it to guide the cyclical movement of the handrail;

[0009] In this setup, the tempered glass support provides excellent structural stability and light transmittance, while the track guides the handrail to move cyclically along a fixed trajectory, providing a reliable installation foundation and a stable detection environment for the alarm mechanism.

[0010] Preferably, the outer peripheral surface of the convex tube is threaded and threadedly connected to two handles. The two handles are located on the left and right sides of the sleeve rod, respectively. By tightening the two handles in the direction of the sleeve rod, the position of the sleeve rod can be restricted on the convex tube.

[0011] In this configuration, the threaded handle can be fixed in position by pressing the sleeve rod, and the height of the sleeve rod on the convex tube can be flexibly adjusted to adapt to different specifications of escalator structures.

[0012] Preferably, the convex tube is connected to the inner side of the suction cup, and the outer end of the convex tube is threaded with an end plug;

[0013] In this setup, the convex tube connects to the suction cup to adjust the negative pressure inside the suction cup, and the end plug maintains the negative pressure state through threaded sealing, enhancing the suction cup's adsorption stability.

[0014] Preferably, the sleeve rod has a sleeve cavity, the bottom end of the sleeve cavity is open, and the sleeve seat extends into the sleeve cavity and can move along the sleeve cavity;

[0015] In this setup, the cavity provides space for the sleeve to move, and the sliding fit between the two can adjust the position of the sensing components to ensure that the rollers are in close contact with the handrail.

[0016] Preferably, the outer end of the sleeve rod is provided with a protruding sleeve, the interior of the protruding sleeve is connected to the sleeve cavity, a spring is sleeved inside the protruding sleeve, a push block is provided on the outer end face of the top of the sleeve seat, the push block extends into the protruding sleeve, and the top of the spring abuts against the bottom surface of the push block;

[0017] In this setup, the sleeve provides mounting space for the spring, which applies elastic force to the sleeve via the push block, ensuring that the roller remains in contact with the handrail.

[0018] Preferably, the rotation direction of the roller is the same as the movement direction of the handrail on one side of the escalator. When the handrail moves, it will drive the roller to rotate synchronously. The rotating shaft of the roller passes through the base axially and extends outward. The detection end of the speed sensor faces the rotating shaft of the roller.

[0019] In this setup, the rollers and handrails rotate synchronously to reflect the handrail's movement status. The extended shaft, in conjunction with the speed sensor's detection end facing it, can accurately obtain the roller's rotational speed information.

[0020] Preferably, the alarm is an audible and visual alarm with a built-in processing unit. When the speed sensor detects that the rotational speed of the roller is zero, the alarm is triggered and the alarm sounds.

[0021] In this setting, the processing unit can receive and judge the signal from the speed sensor. When the rotation speed is zero, it triggers an audible and visual alarm to indicate that the escalator is stopped through sound and light.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This escalator stop alarm device can be directly attached to the support on one side of the escalator using suction cups in the mounting arm assembly, without the need for additional tools, enabling quick installation. At the same time, the sliding connection between the sleeve rod and the sleeve base, and the restriction of the sleeve rod position by the handle, allow for flexible adjustment of the position of the sensing component to adapt to different specifications of escalator handrails. This design also makes the device portable and easy to install, allowing for disassembly, assembly, and position adjustment as needed. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Please see Figures 1-5 An escalator stop alarm device includes an escalator side 100, which comprises a base, handrail, and support. The support is made of tempered glass and has a track installed on it to guide the cyclical movement of the handrail. The tempered glass support not only has good light transmission but also provides a stable mounting base for the alarm mechanism 200. The alarm mechanism 200 is installed on the escalator side 100. The alarm mechanism 200 includes a mounting arm assembly 210 attached to the escalator side 100 and a sensing component 220 mounted on the mounting arm assembly 210. The mounting arm assembly 210 connects and fixes the device to the escalator, and the sensing component 220 detects the escalator's operating status and triggers the alarm. Together, they complete the escalator stop alarm function.

[0036] like Figure 3As shown, in this utility model, the mounting arm assembly 210 includes a sleeve rod 211 and a suction cup 212 adsorbed onto the surface of one side 100 of the escalator. The suction cup 212 is made of elastic rubber and can be tightly adsorbed onto the tempered glass surface through internal negative pressure, without the need for drilling or bolt fixing, which facilitates quick installation and disassembly. The tail end of the suction cup 212 is provided with a protruding tube 2121, which is connected to the inner side of the suction cup 212. The protruding tube 2121 can be used to draw air to enhance the adsorption force of the suction cup 212 and also facilitates the release of negative pressure to disassemble the suction cup 212. The outer end of the protruding tube 2121 is threadedly connected to an end plug 2123, which seals the protruding tube 2121 through the thread, maintaining the negative pressure state inside the suction cup 212 and ensuring adsorption stability.

[0037] like Figure 2 and Figure 3 As shown, specifically, the convex tube 2121 passes through the sleeve rod 211 from the top. The outer circumferential surface of the convex tube 2121 is threaded and threaded with two handles 2122. The handles 2122 are made of plastic and have anti-slip textures on the surface for easy manual tightening. The two handles 2122 are located on the left and right sides of the sleeve rod 211 respectively. By tightening the two handles 2122 in the direction of the sleeve rod 211, the position of the sleeve rod 211 can be restricted on the convex tube 2121. By tightening the handles 2122, the height of the sleeve rod 211 on the convex tube 2121 can be fixed, thereby adjusting the relative position of the sensing component 220 and the handrail to adapt to handrails of different thicknesses.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, the sensing component 220 further includes a base 221 disposed below the sleeve rod 211 and a roller 222 rotatably connected to the base 221. The base 221 is made of ABS engineering plastic, which has certain structural strength and lightweight characteristics. The outer peripheral surface of the roller 222 abuts against the handrail surface of the escalator single side 100. The roller 222 is made of wear-resistant rubber material, which can rotate synchronously with the handrail and reduce wear on the handrail surface. The rotation direction of the roller 222 is the same as the movement direction of the handrail on the escalator single side 100. When the handrail moves, it will drive the roller 222 to rotate synchronously. This synchronous rotation relationship allows the rotation speed of the roller 222 to accurately reflect the running state of the handrail. The rotating shaft of the roller 222 passes through the base 221 axially and extends outward. The extended rotating shaft facilitates the speed sensor 223 to detect its rotation speed.

[0039] like Figure 4 and Figure 5As shown, the top of the base 221 is provided with a sleeve 2211, and a sleeve cavity 2111 is opened inside the sleeve rod 211. The bottom end of the sleeve cavity 2111 is open. The sleeve 2211 extends into the sleeve cavity 2111 and can move along the sleeve cavity 2111, so that the sleeve 2211 is fitted inside the sleeve rod 211 and is slidably connected to the sleeve rod 211. The sliding fit between the sleeve 2211 and the sleeve cavity 2111 can adjust the height of the sensing component 220 and ensure that the roller 222 is in close contact with the handrail. The outer end of the sleeve rod 211 is provided with a protruding sleeve 2112, the interior of which is connected to the sleeve cavity 2111. A spring 2113 is fitted inside the protruding sleeve 2112. The spring 2113 is made of stainless steel and has good elasticity and corrosion resistance. A push block 2212 is provided on the outer end face of the top of the sleeve seat 2211. The push block 2212 extends into the protruding sleeve 2112. The top of the spring 2113 abuts against the bottom surface of the push block 2212. The spring 2113 applies a downward elastic force to the sleeve seat 2211 through the push block 2212, so that the roller 222 always keeps in contact with the surface of the handrail, avoiding poor contact due to slight shaking of the handrail.

[0040] like Figure 5 As shown, it is worth noting that a speed sensor 223 is mounted on the outer end face of the base 221. The speed sensor 223 is used to detect the rotational speed of the roller 222. The speed sensor 223 is a non-contact Hall sensor, which has high detection accuracy and is not easily affected by wear. A seat plate 2213 is provided on the outer end of the base 221, and an alarm 224 is mounted on the top of the seat plate 2213. The seat plate 2213 provides a stable mounting platform for the alarm 224. The detection end of the speed sensor 223 faces the rotation axis of the roller 222. This orientation design ensures that the sensor can accurately capture the rotation signal of the shaft. The alarm 224 is an audible and visual alarm with a built-in processing unit. When the speed sensor 223 detects that the rotational speed of the roller 222 is zero, it triggers the alarm and causes the alarm 224 to sound. The audible and visual alarm method can attract the attention of surrounding personnel simultaneously through sound and light, improving the effectiveness of the alarm.

[0041] In this embodiment, the escalator stop alarm device works as follows: First, the suction cup 212 is attached to the tempered glass surface of one side 100 of the escalator. After the suction force is enhanced by evacuating air through the convex tube 2121, the end plug 2123 is tightened. The handle 2122 is loosened to adjust the height of the sleeve rod 211 so that the roller 222 abuts against the handrail surface. Then, the handle 2122 is tightened to fix the position of the sleeve rod 211. Next, the spring 2113 pushes the sleeve 2211 downward through the push block 2212 to ensure that the roller 222 is in close contact with the handrail. When the handrail moves, it drives the roller 222 to rotate synchronously. The speed sensor 223 detects the rotation speed of the roller 222 in real time. Then, when the escalator stops and the handrail stops moving, the rotation speed of the roller 222 drops to zero. The speed sensor 223 transmits the signal to the processing unit of the alarm 224. Finally, the processing unit triggers the alarm, causing the alarm 224 to emit an audible and visual alarm to indicate that the escalator has stopped.

[0042] Example 2

[0043] To prevent the single suction cup 212 from failing to securely fix the alarm mechanism 200 on one side 100 of the escalator, such as... Figure 2 and Figure 6 As shown, anti-detachment brackets 230 are installed on the outer side of the convex tube 2121 and on the other side of the escalator single side 100. The anti-detachment bracket 230 includes an end plate 231 and several magnetic blocks 232. The end plate 231 is made of lightweight alloy material, which ensures structural strength while reducing weight. Several connecting arms 2311 are provided on the outer periphery of the magnetic blocks 232. The end of the connecting arm 2311 is provided with an end post 2312. The connecting arms 2311 and the end post 2312 enhance the connection stability between the end plate 231 and the magnetic blocks 232. The magnetic blocks 232 are embedded in the end plate 231 close to the escalator single side. On one side end face of edge 100, the outer end faces of the magnets 232 on the same anti-detachment bracket 230 have the same polarity. The corresponding magnets 232 on the two anti-detachment brackets 230 have different polarities. The two anti-detachment brackets 230 are attracted to the tempered glass on both sides of one side 100 of the escalator under the action of magnetism. The magnetic effect of opposite polarities attracting each other makes the anti-detachment brackets 230 clamp the glass, which cooperates with the suction cup 212 to form a double fixation. At this time, the suction cup 212 is pressed tightly on the glass to prevent the suction cup 212 from accidentally falling off during adsorption, which further improves the stability of the alarm mechanism 200 installation.

[0044] It is worth noting that the speed sensor 223 and alarm 224 involved in this utility model are existing conventional technologies. When the escalator stops due to a malfunction or other reasons, the handrail stops moving, and the rollers 222 that abut against the handrail surface also stop rotating, and the rotation of their shafts also stops synchronously. After the speed sensor 223 detects that the rotation speed of the rollers 222 has dropped to zero, it immediately transmits this signal to the processing unit of the alarm 224. After receiving the signal that the rotation speed is zero, the processing unit determines that the escalator has stopped and immediately triggers the alarm mechanism, causing the alarm 224, an audible and visual alarm, to emit sound and light alarms, thereby notifying surrounding personnel that the escalator has stopped running. The core principle of this process is to use the synchronous rotation relationship between the rollers 222 and the handrail to convert the motion state of the handrail into the rotation speed signal of the rollers 222. The speed sensor 223 monitors the rotation speed signal, and then the processing unit of the alarm 224 judges and responds to the signal, ultimately realizing the escalator stop alarm function. This will not be elaborated further in this utility model.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
