Description

Technical Field

[0001] This application relates to the field of safety production equipment technology, and in particular to a safety detection device and system for a safety rope. Background Technology

[0002] In high-altitude operations, safety harnesses are used to ensure the safety of workers and prevent injuries from falls or sudden movements. For example, pole-mounting safety harnesses use ropes or straps wrapped around a fixed structure to secure the worker to the vicinity of the structure, allowing the worker's hands to perform other tasks.

[0003] Safety harnesses should be used with the safety rope attached high and used low. This means attaching the safety harness hook high up while the worker works below. This is a safer and more scientifically sound method, reducing the actual impact distance in the event of a fall. Conversely, "low and high" means attaching the safety harness hook low while the worker works above. Ensuring the correct use of safety harnesses effectively guarantees personnel safety.

[0004] However, in many situations, due to various factors such as operator error or forgetting to operate, the device may be used with a low mounting position and high usage position. This may lead to danger if the operator performs work in this state. Summary of the Invention

[0005] The purpose of this application is to provide a safety detection device and system for safety ropes, which can quickly and accurately identify when a safety rope is used at a low angle and is being used at a high angle, thereby reminding workers to use the safety rope correctly and effectively ensuring personnel safety.

[0006] This application provides a safety detection device for a safety rope, detachably mounted on a hook of the safety rope, comprising:

[0007] A substrate has a cavity inside, the cavity including a first region and a second region; a magnetic element is disposed inside the cavity, and the magnetic element is movable inside the cavity.

[0008] The detection element is configured to correspond to the cavity.

[0009] When the safety rope is in a high-hanging, low-use state with the hook on top, the magnetic element is in the second region under the influence of gravity, and the detection element is facing the region where the magnetic element is located, emitting a sensing signal; when the safety rope is in a low-hanging, high-use state with the hook on the bottom, the magnetic element is in the first region, and the detection element is away from the region where the magnetic element is located.

[0010] In one embodiment, the first region is a non-sensing region, the second region is a sensing region, and the detection element is aligned with the second region.

[0011] In one embodiment, there are multiple detection elements and multiple cavities, with each detection element and cavity corresponding to another. Even if one detection element malfunctions or is interfered with, the other detection elements can still work normally, which greatly improves the reliability and fault tolerance of the system and reduces the possibility of false alarms.

[0012] In one embodiment, the security detection device further includes: a bottom shell, the bottom shell including a first latch;

[0013] The base plate includes a second latch; the second latch cooperates with the first latch to connect the bottom shell and the base plate; this allows operators to quickly check the status of the device before each use to ensure its normal operation, and also allows the device to be easily opened for inspection or maintenance.

[0014] In one embodiment, the outer surface of the bottom shell is provided with elastic claws for engaging with the safety rope. The elastic claws allow the safety rope to be quickly inserted into the detection device and secured without complex tools or additional operating steps, greatly improving work efficiency and reducing potential risks caused by complex operations.

[0015] In one embodiment, the security detection device further includes:

[0016] The circuit board, and the detection components are fixed on the surface of the circuit board;

[0017] The battery, located on the back of the board, connects to the detection element and powers it. Fixing the detection element to the board surface shortens the signal transmission path between the detection element and the board, reducing signal loss and interference, and helping to improve detection accuracy and response speed.

[0018] In one embodiment, a screw post is fixed to the inner surface of the bottom shell, and the plate is provided with a through hole corresponding to the screw post. The screw post and the through hole are connected by screws to fix the bottom shell and the plate.

[0019] In one embodiment, the security detection device further includes:

[0020] A sealing plate is used to seal cavities to prevent magnetic components from accidentally falling out of the cavities during use.

[0021] In one embodiment, the detection element is a Hall sensor or a reed switch. The detection element has a fast response speed and can monitor the position changes of the magnetic element in real time, which helps to detect and handle abnormal situations in a timely manner and improve the system's response speed and safety.

[0022] This application also provides a safety detection system for a safety rope, applied to the aforementioned safety detection device; and further includes:

[0023] The receiving device is wirelessly connected to the safety detection device and can receive induction signals from the device in real time. When it detects an incorrect "low-hanging, high-use" operation of the safety rope, it immediately issues a clear alarm (such as sound, vibration, or light) to remind the operator to correct the attachment method in time. This helps to identify and solve problems as soon as possible and avoid potential safety hazards.

[0024] The advantages of this application compared with the prior art are as follows: This application sets a detection element in the bottom shell and sets a cavity in the substrate. The cavity includes a first region, a second region and a magnetic element that can move in the cavity. When the magnetic element is in the first region, the detection element sends a signal to indicate that a low hanging and high use situation has occurred, reminding the operator to use the safety rope correctly, thereby effectively ensuring the safety of personnel.

Therefore, they should not be construed as limitations on this application.

[0039] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0040] Figure 1 This is an exploded schematic diagram of a safety detection device for a safety rope provided in one embodiment of this application, as shown below. Figure 1 As shown, the safety detection device includes: a substrate 200 and a detection element 310. A cavity 210 is provided within the substrate 200, and the cavity 210 is correspondingly disposed with the detection element 310. A magnetic element 220 is provided within the cavity 210, and the magnetic element 220 can move freely within the cavity 210. The cavity 210 includes a first region 211 and a second region 212. In one embodiment, only one cavity 210 and one detection element 310 may be provided, with the cavity 210 aligned with the detection element 310.

[0041] In one embodiment, the detection element 310 may be aligned with the second region 212; when the detection element 310 generates a sensing signal, the magnetic element 220 is considered to be in the second region 212, and when the detection element 310 does not generate a sensing signal, the magnetic element is considered to be in the first region 211. In other embodiments, when the magnetic element 220 is in the first region 211, the detection element 310 may generate a first sensing signal, and when the magnetic element 220 is in the second region 212, the detection element 310 may generate a second sensing signal.

[0042] In another embodiment, the detection element 310 can also be aligned with the first region 211. When the detection element 310 does not generate a sensing signal, it is assumed that the magnetic element 220 is in the second region 212. When the detection element 310 generates a sensing signal, it is assumed that the magnetic element 220 is in the first region 211. Similarly, when the magnetic element 220 is in the first region 211, the detection element 310 can generate a first sensing signal. When the magnetic element 220 is in the second region 212, the detection element 310 can generate a second sensing signal.

[0043] Therefore, the presence or absence of a sensing signal, or the type of sensing signal, can determine whether the magnetic element 220 is in the first region 211 or the second region 212. For better understanding of this application, the following explanation uses the alignment of the detection element 310 with the second region 212 as an example. In this case, the first region 211 can also be referred to as the non-sensing region, and the second region 212 as the sensing region. The magnetic element 220 can be a magnet. The detection element 310 is a Hall sensor or a reed switch. When the magnet is in the non-sensing region, the detection element 310 does not emit a sensing signal; when the magnet is in the sensing region, the detection element 310 emits a sensing signal.

[0044] When the safety detection device is installed on the safety rope, the first area 211 is closer to the hook of the safety rope, and the second area 212 is farther away from the hook of the safety rope. The hook of the safety rope can be tied to a fixed structure, so that workers can perform high-altitude operations via the safety rope. Of course, the hook here can also be in the form of a strap, as long as it can be tied to a fixed structure.

[0045] When the safety rope is used with a high sling and a low sling, the magnetic element 220 is in the second region 212 under the action of gravity, so that the magnetic element 220 is aligned with the detection element 310; the detection element 310 emits a sensing signal, which can determine that the magnetic element 220 is in the second region 212, and the safety rope is used with a high sling and a low sling, which is the correct operation.

[0046] When the safety rope is used with a low hook and a high position, the hook is at a low position relative to the worker. At this time, the magnetic element 220 is in the first region 211 under the action of gravity. At this time, the magnetic element 220 is far away from the detection element 310, and the detection element 310 does not emit a sensing signal. Therefore, it can be determined that the magnetic element is in the first region 211, and the low hook and high position of the safety rope is an incorrect operation.

[0047] This application utilizes the relative height difference between the safety rope hook's attachment position and the person's position, using gravity to drive the movement of the magnetic element 220 within the cavity 210. The cavity 210 includes a first region 211, a second region 212, and the magnetic element 220 capable of moving within the cavity 210. When the magnetic element 220 is in the second region 212, the detection element 310 emits a sensing signal, indicating high attachment and low use; when the magnetic element 220 is in the first region 211, the detection element 310 does not emit a sensing signal, indicating low attachment and high use. When a low attachment and high use situation occurs, it can promptly remind the operator to operate correctly and avoid problems.

[0048] Figure 2 This is a schematic diagram of the bottom shell structure provided in one embodiment of this application. Figure 3 This is a schematic diagram of a substrate structure provided in an embodiment of this application, as shown below. Figure 1-3 As shown, the safety detection device also includes a base shell 100, which includes a first buckle 120; the base plate 200 includes a second buckle 230; the second buckle 230 cooperates with the first buckle 120 to connect the base shell 100 and the base plate 200. An elastic claw 110 is provided on the outer surface of the base shell 100, which is used to engage with the safety rope, thereby ensuring that the detection device can be accurately installed on the safety rope and monitor the usage status of the safety rope in real time.

[0049] The first buckle 120 is a male buckle, and the second buckle 230 is a female buckle. The elastic claw 110 is adjustable to accommodate safety ropes of different diameters and types. The elastic claw 110 is typically made of high-strength, wear-resistant elastic material to ensure it will not easily loosen or detach from the safety rope during use, providing a reliable fixation effect. The elastic claw 110 can be equipped with multiple locking mechanisms, such as spring pins or buckles, further enhancing the stability of the fixation. Even under external impact or vibration, the safety rope remains firmly fixed to the device. The elastic claw 110 can also be used for other types of quick-fixing devices, such as clamps or hooks.

[0050] In one embodiment, Figure 4 This is a schematic diagram of the overall structure of the detection device provided in one embodiment of this application, as shown below. Figure 1-4As shown, the safety detection device also includes a board 300 and a battery 320. The board 300 is disposed between the bottom shell 100 and the substrate 200. A detection element 310 is fixed to the surface of the board 300 near the substrate 200. The battery 320 is disposed on the surface of the board 300 near the bottom shell 100 and is connected to the detection element 310, providing power to the detection element 310 and ensuring the stability of the power supply. The board 300 is a PCB (Printed Circuit Board). In one embodiment, the board 300 can receive sensing signals from the detection element 310 and perform corresponding logical judgments. For example, when a sensing signal is received, it determines "low connection, high use" and triggers an alarm. If necessary, the board 300 can also send the received sensing signals to an external device for low connection, high use determination.

[0051] In one embodiment, the safety detection device further includes a sealing plate 400, which is located on the side of the substrate 200 away from the bottom shell 100. The sealing plate 400 is used to seal the cavity 210 to ensure the stable movement of the magnetic element 220 within the cavity. At the same time, it prevents dust, moisture and other impurities from entering the cavity 210, thereby affecting the normal movement of the magnetic element 220 and the detection accuracy of the detection element 310, and ensuring that the entire detection device can operate stably and reliably for a long time.

[0052] In one embodiment, a screw post 130 is fixed to the inner surface of the bottom shell 100, and the plate 300 is provided with a through hole 330 corresponding to the screw post 130. The screw post 130 and the through hole 330 are connected by screws to fix the bottom shell 100 and the plate 300. The connection between the screw post 130 and the through hole 330 can be other mechanical connection methods, such as adhesive, welding, etc.

[0053] The testing device of this application uses a first buckle 120, a second buckle 230, a screw post 130, and a through hole 330 to detachably fix the base plate 200, the bottom shell 100, and the board 300, which facilitates the maintenance and repair of the testing device. At the same time, the overall structure of the testing device is simple, the cost is low, the production efficiency is improved, and the user's safety and ease of operation are ensured.

[0054] In one embodiment, such as Figure 4As shown, there are multiple detection elements 310 and multiple cavities 210, with each detection element 310 and cavity 210 corresponding to another. The number and distribution of the detection elements 310, cavities 210, and magnetic elements 220 can be adjusted according to actual needs to meet specific requirements in different scenarios. The first area 211 of the safety detection device has a hook installed close to the safety rope, while the second area 212 has a hook away from the safety rope. When the safety rope is used with a high-hanging, low-using configuration, the magnetic elements 220 are positioned in the second area 212 under gravity, thus corresponding to the detection elements 310. When the detection element 310 detects that more than half or all of the magnetic elements 220 are in the second area 212, it is determined that the safety rope is used with a high-hanging, low-using configuration, which is a correct operation. When the safety rope is used with a low sling and a high sling, the magnetic element 220 is in the first region 211 under the action of gravity, and the detection element 310 senses the region where the magnetic element 220 is located. When the detection element 310 detects that more than half or all of the magnetic elements 220 are in the first region 211, it is determined that the safety rope is used with a low sling and a high sling, which is an incorrect operation.

[0055] In one embodiment, this application also provides a safety detection system for a safety rope, including the aforementioned safety detection device and a receiving device (not shown in the figure), wherein the receiving device is wirelessly connected to the safety detection device. For example, when the receiving device receives a sensing signal emitted by the detection element 310, it issues an alarm to the operator, reminding the operator of a situation where the rope is used too low and the rope is used too high, prompting the operator to perform the correct operation. The receiving device can be installed on the safety belt, allowing the operator to receive alarm information promptly, ensuring that the operator receives alarm information even in complex working environments. The wireless communication connection method includes WAPI (Wireless Authentication Protocol for Internet) or Bluetooth Low Energy. The receiving device can be portable, fixed, or other forms to meet the needs of different users. For example, the receiving device can be a wearable device that can be worn directly on the operator's body. Personalized alarm reminders (such as vibration, sound, light, etc.) can also be set according to each operator's habits and needs to improve the user experience.

[0056] The components of this application can be modularly designed, facilitating functional expansion and upgrades. This application utilizes the relative height difference between the safety rope hook and the worker, along with gravity, to drive the movement of the magnetic element 220. Multiple detection elements 310 are configured to correspond one-to-one with multiple cavities 210 and multiple magnetic elements 220. The correctness of the operation is determined by the location of more than half or all of the magnetic elements 220, further reducing misjudgments and improving detection accuracy. The detection elements 310 monitor and sense the position of the magnetic elements 220 in real time to determine whether the safety rope is in the correct "high-hanging, low-use" or incorrect "low-hanging, high-use" operation. By wirelessly connecting the receiving device to the safety detection device, when the detection element 310 detects an incorrect operation and sends a signal, the receiving device can issue an alarm to the worker, reminding them to correct the attachment position in time and avoid safety hazards caused by incorrect use of the safety rope. Furthermore, this device is suitable for various high-altitude work environments, such as construction, bridge maintenance, and power maintenance. Besides high-altitude operations, the technical solution of this application can also be applied to other scenarios requiring safety ropes, such as mountaineering, rock climbing, and fire rescue. With appropriate adjustments and optimizations, the detection device of this application can meet the special needs of different fields, provide more comprehensive safety assurance, and effectively protect the safety of personnel.

[0057] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other. The above are merely preferred embodiments of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
