Description

Technical Field

[0001] This utility model relates to the field of elevators, and in particular to an escalator with safety protection functions. Background Technology

[0002] With the continuous improvement of living standards and industrialization, escalators have been widely used in public places such as shopping malls, stations, airports, and hotels, becoming an important means of transportation to guide crowds and facilitate people's walking, bringing great convenience to people's work and life.

[0003] Because a certain clearance must be maintained between the steps and the skirt panels of escalators, accidents frequently occur where children's feet, along with their Crocs, get caught in this clearance and are struck at the escalator's comb-like entrances and exits. To improve escalator safety, existing technology incorporates mechanical limit switches (i.e., skirt panel protection switches) at the skirt panels. However, these mechanical limit switches typically only activate when physically deformed by the skirt panel and usually only protect one point, exhibiting drawbacks such as insensitive operation and insufficient protection area. Utility Model Content

[0004] Therefore, it is necessary to provide an escalator with safety protection functions to address the problems of insensitive operation and insufficient protection area of ​​existing mechanical limit switches.

[0005] The technical solution is as follows:

[0006] On the one hand, an escalator with safety protection functions is provided, including:

[0007] Safety protection devices;

[0008] The skirt board is provided with an anti-pinch protection area, and the anti-pinch protection area is provided with a detection point;

[0009] A deformation detection device is located on one side of the anti-pinch protection area and is communicatively connected to the safety protection device. The deformation detection device is used to detect the deformation value at the detection point, and triggers the safety protection device when the deformation value detected by the deformation detection device reaches a preset value.

[0010] In the above-described embodiment of the escalator with safety protection function, during use, the anti-pinch protection area is equipped with detection points corresponding to the deformation detection device. When different locations within the anti-pinch protection area are subjected to force and deform, the detection points will generate different degrees of deformation. The deformation detection device detects the deformation value at the detection point in real time. When a pinching accident occurs in the anti-pinch protection area, the deformation detection device detects that the deformation value at the detection point is greater than a preset value and sends a trigger signal to the safety protection device. The safety protection device then operates according to the trigger signal to stop the escalator. This application can provide anti-pinch protection for the entire anti-pinch protection area with a single deformation detection device, significantly increasing the area of ​​the anti-pinch protection area and improving the reliability of the escalator with safety protection function. In addition, the deformation detection device detects the deformation value at the detection point in real time, and controls whether the safety protection device is activated by the relationship between the detected deformation value and the preset value. This digital control and protection method can improve the sensitivity of the action protection. At the same time, the sensitivity of the action protection can be adjusted according to actual needs. For skirts of different materials and thicknesses, only the size of the preset value needs to be adjusted accordingly, which has a wider range of applications and improves the adaptability of escalators with safety protection functions.

[0011] The technical solution will be further explained below:

[0012] In one embodiment, the detection point is set as the geometric center point of the anti-pinch protection area.

[0013] In one embodiment, a simulated point is provided at the position furthest from the detection point in the anti-pinch protection area, and the preset value is set to the deformation value at the simulated point when a simulated force is applied to the simulated point.

[0014] In one embodiment, the preset value is greater than or equal to 0.1 mm.

[0015] In one embodiment, the escalator with safety protection function further includes steps, and the number of skirts is at least two, with each skirt being spaced apart on opposite sides of the steps, and the deformation detection device is installed on the side of the skirt away from the steps.

[0016] In one embodiment, the number of deformation detection devices is at least two, each of the deformation detection devices is installed on opposite sides of the ladder step and is configured to correspond one-to-one with the anti-pinch protection area on each of the skirts, and all the deformation detection devices located on the same side of the ladder step are arranged along the moving direction of the ladder step.

[0017] In one embodiment, two adjacent anti-pinch protection areas located on the same side of the ladder are connected.

[0018] In one embodiment, the deformation detection device includes a first mounting bracket and a deformation detection component, wherein the deformation detection component is mounted on the first mounting bracket.

[0019] In one embodiment, the deformation detection element is spaced apart from the skirt panel.

[0020] In one embodiment, the deformation detection element is configured as one of an electromagnetic eddy current sensor, a 3D infrared TOF sensor, an ultrasonic sensor, and a pressure sensor. Attached Figure Description

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, an escalator 10 with safety protection function is provided, including a safety protection device (not shown), a skirt panel 100, and a deformation detection device 200. The skirt panel 100 has an anti-pinch protection area 110. The anti-pinch protection area has detection points. The deformation detection device 200 is located on one side of the anti-pinch protection area 110 and is communicatively connected to the safety protection device. The deformation detection device 200 is used to detect the deformation value at the detection point, and triggers the safety protection device when the deformation value detected by the deformation detection device 200 reaches a preset value.

[0030] In the above embodiment, the escalator 10 with safety protection function has detection points corresponding to the deformation detection device 200 in the anti-pinch protection area 110. When different positions within the anti-pinch protection area 110 are subjected to force and deform, the detection points will generate different degrees of deformation. The deformation detection device 200 detects the deformation value at the detection point in real time. When a pinching accident occurs in the anti-pinch protection area 110, the deformation detection device 200 detects that the deformation value at the detection point is greater than a preset value and sends a trigger signal to the safety protection device. The safety protection device then operates according to the trigger signal to stop the escalator. This application can provide anti-pinch protection for the entire anti-pinch protection area 110 with just one deformation detection device 200, significantly increasing the area of ​​the anti-pinch protection area 110 and improving the reliability of the escalator 10 with safety protection function. In addition, the deformation detection device 200 detects the deformation value at the detection point in real time, and controls whether the safety protection device is activated by the relationship between the detected deformation value and the preset value. That is, the digital control and protection method can improve the sensitivity of the action protection. At the same time, the sensitivity of the action protection can be adjusted according to actual needs. For skirts 100 of different materials and thicknesses, only the size of the preset value needs to be adjusted accordingly, which has a wider range of applications and improves the adaptability of the escalator 10 with safety protection function.

[0031] It should be noted that the escalator 10 with safety protection functions includes, but is not limited to, moving walkways. The escalator 10 with safety protection functions can be horizontal or at a certain angle.

[0032] The safety protection device can be any existing elevator safety protection structure. The deformation detection device 200 can communicate with the safety protection device via data cable, power cable, Bluetooth, wireless communication network technology, or other communication methods.

[0033] The preset value can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the preset value ranges from 0.1 mm to 0.1 mm. For example, the preset value can be 0.2 mm, 0.5 mm, 1 mm, 2 mm, or 3 mm.

[0034] like Figure 1 As shown, optionally, the detection point is set as the geometric center point of the anti-pinch protection area 110. Thus, the detection point of the deformation detection device 200 is the detection point of the anti-pinch protection area 110. When an accident occurs at different locations within the anti-pinch detection area, the deformation value at the detection point is relatively more concentrated, making it easier to screen out situations where deformation at the detection point is clearly not caused by a pinching accident. This increases the accuracy of the safety protection device's protective shutdown action and improves the reliability of the escalator 10 with safety protection functions.

[0035] In this embodiment, the anti-pinch protection area 110 can be rectangular. In other embodiments, the anti-pinch protection area 110 can also be fan-shaped, trapezoidal, or other shapes.

[0036] Optionally, a simulated point is provided at the location furthest from the detection point in the anti-pinch protection zone 110. A preset value is set to the deformation at the simulated point when a simulated force is applied. Thus, within the anti-pinch protection zone 110, the farther the pinching location is from the detection point, the smaller the deformation at the detection point. By selecting the simulated point (i.e., the location where a simulated pinching accident occurs) at the location furthest from the detection point within the protection zone, it is ensured that when a pinching accident occurs at any location within the anti-pinch protection zone 110, the deformation detection device 200 can detect it and correspondingly control the safety protection device to operate, thereby improving the reliability of the escalator 10 with safety protection functions.

[0037] It should be noted that the simulated force refers to the force exerted on the clamping position during a simulated clamping accident. The magnitude of the simulated force can be selected with reference to the magnitude of the force exerted on the clamping position during an actual clamping accident.

[0038] like Figure 2 and Figure 3As shown, in one embodiment, the escalator 10 with safety protection function further includes steps 300. There are at least two skirts 100, each skirt 100 being spaced apart on opposite sides of the steps 300. A deformation detection device 200 is installed on the side of the skirt 100 away from the steps 300. Thus, the skirts 100 can isolate the deformation detection device 200 from the external environment, preventing interference from objects in the external environment, ensuring that the deformation detection device 200 can reliably and stably detect the deformation at the detection point, and improving the reliability of the escalator 10 with safety protection function.

[0039] It should be noted that step 300 includes, but is not limited to, pedals.

[0040] The installation position of the deformation detection device 200 can be flexibly adjusted according to actual usage needs.

[0041] like Figure 1 As shown, specifically in this embodiment, the deformation detection device 200 is installed on the skirt panel 100 at the lower turning position of the escalator 10, where a trapping accident is likely to occur.

[0042] like Figure 3 As shown, the number of deformation detection devices 200 is at least two. Each deformation detection device 200 is installed on opposite sides of the step 300 and corresponds one-to-one with the anti-pinch protection area 110 on each skirt panel 100. All deformation detection devices 200 located on the same side of the step 300 are arranged along the moving direction of the step 300. In this way, each anti-pinch protection area 110 on each skirt panel 100 is provided with a deformation detection device 200, ensuring that when a pinching accident occurs in the anti-pinch protection areas 110 on opposite sides of the step 300, the deformation detection device 200 can detect it and trigger the safety protection device to operate, thereby improving the safety of the escalator 10 with safety protection function.

[0043] It should be noted that the number of anti-pinch protection areas 110 on each skirt board 100 can be flexibly adjusted according to actual usage needs. For example, the number of anti-pinch protection areas 110 on the skirt board 100 can be zero, one, two, or more.

[0044] In this specific embodiment, the number of deformation detection devices 200 is the same as the number of anti-pinch protection areas 110.

[0045] Optionally, two adjacent anti-pinch protection areas 110 located on the same side of the step 300 are connected. In this way, all anti-pinch protection areas 110 located on the same side of the step 300 are connected in sequence to form a detection area, and the detection area is set in accordance with the movement gap between the step 300 and the skirt 100, so as to ensure that when a pinching accident occurs at any position on either side of the step 300, the deformation detection device 200 can quickly detect and trigger the safety protection device to act, thereby improving the safety of the escalator 10 with safety protection function.

[0046] like Figure 2 As shown, in one embodiment, the deformation detection device 200 includes a first mounting bracket 210 and a deformation detection element 220. The deformation detection element 220 is mounted on the first mounting bracket 210. In this way, the deformation detection element 220 is installed and fixed by the first mounting bracket 210, ensuring that the deformation detection element 220 can be set to correspond to the detection point of the anti-pinch protection area 110, thereby improving the convenience of installation of the escalator 10 with safety protection function.

[0047] Specifically, in this embodiment, the deformation detection element 220 can be configured as one of an electromagnetic eddy current sensor, a 3D infrared TOF sensor, an ultrasonic sensor, and a pressure sensor. In other embodiments, the deformation detection element 220 can also be any of the prior art sensors capable of detecting the continuous deformation process at the detection point, representing it with analog data, and converting the analog data into digital data.

[0048] like Figure 2 As shown, optionally, the deformation detection element 220 is spaced apart from the skirt plate 100. In this way, there is no interference between the deformation detection element 220 and the skirt plate 100, ensuring that the deformation detection element 220 can reliably detect the deformation at the detection point on the anti-pinch protection area 110, thereby improving the safety of the escalator 10 with safety protection function.

[0049] Specifically, in this embodiment, when the skirt 100 is not deformed, the side of the skirt 100 near the deformation detection element 220 is perpendicular to the detection surface (or the central axis of the deformation detection element 220).

[0050] like Figure 1 As shown, specifically in this embodiment, the escalator 10 with safety protection function further includes a second mounting bracket 400 for mounting the skirt panel 100, a handrail 500, and a truss 600 for mounting the handrail 500. The first mounting bracket 210 can be mounted on the second mounting bracket 400 or the truss 600.

[0051] like Figure 3As shown, in one embodiment, the escalator 10 with safety protection function includes an analysis controller 700. The analysis controller 700 is communicatively connected to both the deformation detection device 200 and the safety protection device. The analysis controller receives analog data generated by the deformation detection device 200, which varies due to different degrees of deformation at the detection points. It converts the analog data into digital data corresponding to the deformation amount, determines the degree of deformation of the anti-pinch protection area 110 based on the digital data, and then controls the safety protection device to stop the escalator to prevent accidents caused by passengers' body parts or other objects getting caught between the steps 300 and the skirt 100 of the escalator 10 with safety protection function.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0057] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
