Abstract
Description
Technical Field
[0001] This invention relates to the field of protection device technology, and in particular to a trigger protection device and a monitoring protection method. Background Technology
[0002] Currently used limit switches, proximity switches, and other trigger protection devices typically include a fixed end structure and a trigger end structure. The trigger end structure is installed at the moving edge of the protected device. As the protected device moves, it drives the trigger end structure to move synchronously, allowing the trigger end structure to approach or even contact the fixed end structure. When the fixed end structure and the trigger end structure of the trigger protection device approach each other to a certain extent, or when they come into contact, an alarm is triggered, thereby achieving the effect of monitoring and early warning.
[0003] Specifically, in existing technologies, for large protected structures, multiple proximity switches and / or limit switches are typically installed at intervals as triggering protection devices to enhance the reliability of safety protection. While this approach improves the reliability of safety protection, it still has the following drawbacks. Taking multiple proximity switches as the triggering protection device as an example, the following disadvantages exist:
[0004] 1. Multiple proximity switches do not form a continuous, uninterrupted structure, thus failing to provide protection in areas where proximity switches are not installed, resulting in poor performance.
[0005] Second, when the protected structure is an irregular shape, it is difficult to install multiple proximity switches;
[0006] Third, when the space around the protected structure is narrow, it will greatly increase the difficulty of arranging multiple proximity switches.
[0007] Fourth, the installation of multiple proximity switches leads to a high failure rate of the proximity switches, and since multiple proximity switches need to be connected to the control system through wires, line loss will affect the control effect of the equipment control system itself. Summary of the Invention
[0008] The purpose of this invention is to provide a trigger protection device and a monitoring protection method to solve the technical problems mentioned in the background art of using multiple proximity switches and / or limit switches as trigger protection devices at intervals.

[0025] The beneficial effects of this invention are:
[0026] The present invention aims to provide a trigger protection device and a monitoring and protection method. The trigger protection device includes a first housing, a first trigger switch structure, a second trigger switch structure, and a traction support structure. The first trigger switch structure includes a first fixed end structure fixedly disposed within the first housing and a first movable end structure slidably disposed within the first housing. The first movable end structure can contact or separate from the first fixed end structure. The second trigger switch structure includes a second fixed end structure fixedly disposed within the first housing and a second movable end structure. The second movable end structure is configured to connect or separate from the first housing and to contact or separate from the second fixed end structure. When the second movable end structure is connected to the first housing, it contacts the second fixed end structure. The traction support structure includes a traction rope and a bracket. One end of the traction rope passes through the first housing and connects to the first movable end structure, and the other end connects to the second movable end structure. The bracket can be connected to the protected structure and is used to support the traction rope.Specifically, when it is necessary to monitor and protect the protected structure through a trigger protection device, the first housing is connected to the protected structure, so that the integrated structure formed by the first housing, the first trigger switch structure, and the second fixed end structure is connected to the protected structure. The brackets are spaced apart from the first housing and all connected to the protected structure. The traction rope is wrapped around the protected structure and placed on the bracket, so that the traction rope is spaced apart from the protected structure. Then, the second movable end structure is connected to the first housing, so that the first movable end structure contacts the first fixed end structure, and the second movable end structure contacts the second fixed end structure. At this time, the traction rope is taut. The first movable end structure and the first fixed end structure form a loop with the external control system, and the second movable end structure and the second fixed end structure also form a loop with the external control system. It can be understood that the protected structure is wrapped around the traction rope circumferentially and spaced apart from the traction rope, and the traction rope is taut. When an external structure approaches the protected structure, or even contacts the protected structure, it will first approach the traction rope. When the external structure contacts the traction rope and applies a certain force to the traction rope, it... When the traction rope causes the second movable end structure to separate from the first shell, the second movable end structure and the second fixed end structure will separate simultaneously, as will the first movable end structure and the first fixed end structure. At this time, the control system will issue an alarm based on the separation of the first fixed end structure and the first movable end structure, or based on the separation of the second movable end structure and the second fixed end structure, thereby achieving the effect of monitoring and early warning. When the external structure contacts the traction rope, causing the traction rope to break, the traction rope will no longer be taut, and the first movable end structure and the first fixed end structure will inevitably separate. At this time, the control system will issue an alarm based on the separation of the first fixed end structure and the first movable end structure, thereby achieving the effect of monitoring and early warning. When the external structure contacts the support and applies a certain force to the support, causing the support to bend and deform, resulting in the traction rope wrapped around the protected structure and attached to the support losing its support, the traction rope will no longer be taut, and the first movable end structure and the first fixed end structure will inevitably separate. At this time, the control system will issue an alarm based on the separation of the first fixed end structure and the first movable end structure, thereby achieving the effect of monitoring and early warning.
[0027] Therefore, compared with existing technologies, this trigger protection device eliminates the need for multiple proximity switches, saving monitoring costs, facilitating installation, effectively improving the protection effect on the protected structure, and significantly reducing the risk of damage to the device's structure. Secondly, the device's simple structure and small size enhance its applicability to irregularly shaped protected structures and its suitability for situations with limited surrounding space. Furthermore, compared to existing technologies that require multiple proximity switches to be connected in series with the control system via wires, this trigger protection device effectively avoids the problem of line loss affecting the control system's performance, thus further improving the device's performance.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0045] This invention provides a trigger protection device and a monitoring and protection method, such as... Figure 1-3As shown, the trigger protection device includes a first housing 1, a first trigger switch structure 2, a second trigger switch structure, and a traction support structure 4. The first trigger switch structure 2 includes a first fixed end structure 21 fixedly disposed within the first housing 1 and a first movable end structure 22 slidably disposed within the first housing 1. The first movable end structure 22 can contact or separate from the first fixed end structure 21. The second trigger switch structure includes a second fixed end structure 31 fixedly disposed within the first housing 1 and a second movable end structure 32. The second movable end structure 32 is configured to connect or separate from the first housing 1 and to contact or separate from the second fixed end structure 31. When the second movable end structure 32 is connected to the first housing 1, the second movable end structure 32 contacts the second fixed end structure 31. The traction support structure 4 includes a traction rope 41 and a bracket 42. One end of the traction rope 41 passes through the first housing 1 and connects to the first movable end structure 22, and the other end connects to the second movable end structure 32. The bracket 42 can be connected to the protected structure 100 and is used to support the traction rope 41.Specifically, when it is necessary to monitor and protect the protected structure 100 through the trigger protection device, the first housing 1 is connected to the protected structure 100, so that the integral structure formed by the first housing 1, the first trigger switch structure 2, and the second fixed end structure 31 is connected to the protected structure 100. The bracket 42 is spaced apart from the first housing 1 and connected to the protected structure 100. The traction rope 41 is wrapped around the protected structure 100 and placed on the bracket 42, so that the traction rope 41 is spaced apart from the protected structure 100. Then, the second movable end structure 32 is connected to the first housing 1, so that the first movable end structure 22 is in contact with the first fixed end structure 21. The second movable end structure 32 contacts the second fixed end structure 31. At this time, the traction rope 41 is taut. The first movable end structure 22 and the first fixed end structure 21 form a loop with the external control system. The second movable end structure 32 and the second fixed end structure 31 also form a loop with the external control system. It can be understood that the protected structure 100 is wrapped around the traction rope 41 circumferentially and spaced apart from the traction rope 41, and the traction rope 41 is taut. When an external structure approaches the protected structure 100, or even contacts the protected structure 100, it will first approach the traction rope 41. When the external structure contacts the traction rope 41 and applies force to the traction rope 41... When a certain force is applied, causing the traction rope 41 to separate the second movable end structure 32 from the first housing 1, the second movable end structure 32 will simultaneously separate from the second fixed end structure 31, and the first movable end structure 22 and the first fixed end structure 21 will simultaneously separate. At this time, the control system will issue an alarm based on the separation of the first movable end structure 22 and the first fixed end structure 21, or based on the separation of the second movable end structure 32 and the second fixed end structure 31, thereby achieving the effect of monitoring and early warning. When the external structure contacts the traction rope 41 and causes the traction rope 41 to break, the traction rope 41 will no longer be taut, and the first movable end structure 22 and the first fixed end structure 31 will separate. Structure 21 will inevitably separate. At this time, the control system will issue an alarm based on the separation of the first fixed end structure 21 and the first movable end structure 22, thereby achieving the effect of monitoring and early warning. When the external structure contacts the support 42 and applies a certain force to the support 42, causing the support 42 to bend and deform, the traction rope 41 wrapped around the protected structure 100 and attached to the support 42 will lose its support. When the traction rope 41 is no longer taut, the first movable end structure 22 and the first fixed end structure 21 will inevitably separate. At this time, the control system will issue an alarm based on the separation of the first fixed end structure 21 and the first movable end structure 22, thereby achieving the effect of monitoring and early warning.
[0046] Therefore, compared with the prior art, this trigger protection device does not require multiple proximity switches, saving monitoring costs, facilitating installation, effectively improving the protection effect on the protected structure 100, and effectively reducing the risk of damage to the trigger protection device structure. Secondly, the trigger device has a simple structure and small size, which effectively improves its applicability to irregularly shaped protected structures and also improves its applicability to situations where the surrounding space of the protected structure 100 is narrow. Furthermore, compared with the prior art that requires multiple proximity switches to be connected in series with the control system via wires, this trigger protection device can effectively avoid the problem of line loss affecting the control effect of the control system, thereby further improving the performance of the trigger protection device.
[0047] Specifically, in this embodiment, such as Figure 3 As shown, the protected structure 100 is exemplarily represented by a crane. In other embodiments, such as... Figure 4 As shown, the protected structure 100 is exemplarily taken as an aerial work platform. In other embodiments, such as... Figure 5 As shown, a forklift is used as an example of the protected structure 100. It can be understood that this trigger protection device can be applied to various types of protected structures.
[0048] Among them, such as Figure 1 and Figure 2 As shown, the first fixed end structure 21, the first movable end structure 22, and the second fixed end structure 31 are sequentially spaced along a first direction. The trigger protection device also includes a first limiting member 51 fixedly disposed on the first housing 1. The first limiting member 51 is distributed between the first movable end structure 22 and the second fixed end structure 31. The first movable end structure 22 can abut against the first limiting member 51 along the first direction and can also contact the first fixed end structure 21 along the first direction. This arrangement limits the sliding range of the first movable end within the first housing 1, allowing the first movable end structure 22 and the first fixed end structure 21 to effectively contact or separate, and allowing the second fixed end structure 31 to contact or separate from the second movable end structure 32.
[0049] Preferably, such as Figure 3 As shown, there are multiple brackets 42, which are distributed at intervals along the circumference of the protected structure 100. This arrangement facilitates the placement of the traction rope 41. Specifically, the brackets 42 are connected to the protected structure 100 via a detachable connection such as a threaded connection. The first housing 1 is also connected to the protected structure 100 via a detachable connection such as a threaded connection.
[0050] Preferably, in this embodiment, the traction rope 41 is a thin steel wire rope. Steel wire rope has good flexibility, is not easy to break, and is not easily damaged.
[0051] Preferably, the bracket 42 is made of a metal material with good elasticity. This design gives the bracket 42 good elasticity, allowing it to undergo elastic deformation when impacted by an external structure, thereby further improving the safety and reliability of the trigger protection device. Specifically, the bracket 42 is made of a metal material such as aluminum.
[0052] Among them, such as Figure 1-3As shown, the first fixed end structure 21 includes two first conductive fixed blocks 211 detachably connected to the first housing 1 and spaced apart. The first movable end structure 22 includes a sliding block 221, a first conductive movable block 222 disposed on the sliding block 221, and a first elastic member 223. The sliding block 221 is slidably connected to the first housing 1 along a first direction and can abut against the first limiting member 51. The first elastic member 223 is connected to the first housing 1 and the first conductive movable block 222. The first conductive movable block 222 is connected to the traction rope 41. The first conductive fixed block 211 can contact or separate from the first conductive movable block 222. Specifically, the control system is electrically connected to the two first conductive fixed blocks 211 via wires. When the second movable end structure 32 is connected to the first housing 1, such that the first conductive fixed block 211 contacts the first conductive movable block 222, and the second movable end structure 32 contacts the second fixed end structure 31, the traction rope 41 is taut, the first elastic element 223 is compressed, and the first conductive movable block 222 and the two first conductive fixed blocks 211 form a circuit with the external control system. The second movable end structure 32 and the second fixed end structure 31 also form a circuit with the external control system. When the external structure applies a force to the traction rope 41, causing the traction rope 41 to drive the second movable end structure 31... When the second movable end structure 32 separates from the first housing 1, it causes the second fixed end structure 31 to separate synchronously. At this time, the elastic restoring force of the first elastic element 223 drives the sliding block 221 and the first conductive movable block 222 to move away from the first conductive fixed block 211 synchronously along the first direction, causing the first conductive movable block 222 to separate from the first conductive fixed block 211. The control system will issue an alarm based on the separation of the first conductive movable block 222 and the first conductive fixed block 211, or based on the separation of the second movable end structure 32 and the second fixed end structure 31, thereby achieving monitoring and early warning. Effect; When the external structure contacts the traction rope 41, causing the traction rope 41 to break, the traction rope 41 is no longer taut. The elastic restoring force of the first elastic element 223 causes the sliding block 221 and the first conductive movable block 222 to move away from the first conductive fixed block 211 in the first direction, causing the first conductive movable block 222 to inevitably separate from the first conductive fixed block 211. At this time, the control system will issue an alarm based on the separation of the first conductive movable block 222 and the first conductive fixed block 211, thereby achieving the effect of monitoring and early warning; When the external structure contacts the bracket 42 and applies a force to the bracket 42, it will cause the traction rope 41 to break. When the constant force causes the support 42 to bend and deform, the traction rope 41, which is wrapped around the protected structure 100 and attached to the support 42, loses its support. When the traction rope 41 is no longer taut, the elastic restoring force of the first elastic element 223 causes the sliding block 221 and the first conductive movable block 222 to move away from the first conductive fixed block 211 in the first direction, so that the first conductive movable block 222 and the first conductive fixed block 211 will inevitably separate. At this time, the control system will issue an alarm based on the separation of the first conductive movable block 222 and the first conductive fixed block 211, thereby achieving the effect of monitoring and early warning.
[0053] Specifically, such as Figure 1 and Figure 2 As shown, at least the portion of the first conductive fixing block 211 that contacts the first housing 1 is provided with a first insulating pad 212. Since the first conductive fixing block 211 is conductive, the first insulating pad 212 is provided to prevent the first housing 1 from becoming energized, thereby improving the safety and reliability of the trigger protection device.
[0054] Specifically, a fourth insulating pad is provided on at least the portion of the first elastic member 223 that contacts the first conductive movable block 222. This arrangement further prevents the first housing 1 from becoming electrified, thereby further improving the safety and reliability of the trigger protection device.
[0055] Preferably, the first housing 1 is made of metal. This design ensures good structural strength of the first housing 1, and when an external structure impacts the first housing 1, the first housing 1 can protect the first trigger switch structure 2 and the second fixed end structure 31 located inside it, thereby further improving the safety and reliability of the trigger protection device.
[0056] Preferably, such as Figure 1 and Figure 2 As shown, the first movable end structure 22 also includes a first guide post 224. One end of the first guide post 224 is connected to the first conductive movable block 222 along the axial direction, and the other end is slidably connected to the first housing 1. A first elastic member 223 is sleeved on the first guide post 224, and the axial direction of the first guide post 224 is parallel to the first direction. The first guide post 224 can guide the first elastic member 223 to extend and retract only along the first direction, thereby guiding the first conductive movable block 222 and the sliding block 221 to move only along the first direction, improving the working performance of the first trigger switch structure 2.
[0057] Specifically, a fifth insulating layer is provided on at least the portion of the first guide post 224 that contacts the first housing 1 and the first elastic member 223. Alternatively, the first guide post 224 is insulated. This arrangement further prevents the first housing 1 from becoming energized, thereby further improving the safety and reliability of the trigger protection device.
[0058] Among them, such as Figure 1-3As shown, the second fixed end structure 31 includes a second conductive fixing block 311 detachably connected to the first housing 1, and the second movable end structure 32 includes a second housing 321, a second conductive movable block 322 slidably connected to the second housing 321, and a second elastic member 323. The two ends of the second elastic member 323 are respectively connected to the second housing 321 and the second conductive movable block 322. The second housing 321 can be connected to or separated from the first housing 1, and the second conductive movable block 322 can contact or separate from the second conductive fixing block 311. The traction rope 41 is connected to the second housing 321. Specifically, the control system is electrically connected to the two second conductive fixing blocks 311 via wires. When the second housing 321 is connected to the first housing 1, such that the first conductive fixed block 211 contacts the first conductive movable block 222, and the second conductive fixed block 311 contacts the second conductive movable block 322, the traction rope 41 is taut, and both the first elastic element 223 and the second elastic element 323 are compressed. The first conductive movable block 222 and the two first conductive fixed blocks 211 form a circuit with the external control system, and the second conductive movable block 322 and the two second conductive fixed blocks 311 form a circuit with the external control system. When the external structure applies a force to the traction rope 41, causing the traction rope... When the first housing 1 and the second housing 321 are separated, the elastic restoring force of the first elastic element 223 causes the sliding block 221 and the first conductive movable block 222 to move away from the first conductive fixed block 211 synchronously along the first direction, causing the first conductive movable block 222 to separate from the first conductive fixed block 211, and the second conductive movable block 322 and the second conductive fixed block 311 to separate synchronously. The control system will issue an alarm based on the separation of the first conductive fixed block 211 and the first conductive movable block 222, or based on the separation of the second conductive fixed block 311 and the second conductive movable block 322, thereby achieving... The monitoring and early warning effect is as follows: When the external structure comes into contact with the traction rope 41, causing the traction rope 41 to break, the traction rope 41 is no longer taut. The elastic restoring force of the first elastic element 223 causes the sliding block 221 and the first conductive movable block 222 to move away from the first conductive fixed block 211 in the first direction, causing the first conductive movable block 222 to inevitably separate from the first conductive fixed block 211. At this time, the control system will issue an alarm based on the separation of the first conductive movable block 222 and the first conductive fixed block 211, thereby achieving the monitoring and early warning effect; when the external structure comes into contact with the bracket 42 and moves towards the bracket 42... When a certain force is applied to cause the support 42 to bend and deform, the traction rope 41, which is wrapped around the protected structure 100 and attached to the support 42, loses its support. When the traction rope 41 is no longer taut, the elastic restoring force of the first elastic element 223 causes the sliding block 221 and the first conductive movable block 222 to move away from the first conductive fixed block 211 in the first direction, so that the first conductive movable block 222 and the first conductive fixed block 211 will inevitably separate. At this time, the control system will issue an alarm based on the separation of the first conductive movable block 222 and the first conductive fixed block 211, thereby achieving the effect of monitoring and early warning.
[0059] Specifically, such as Figure 1 and Figure 2 As shown, both the first housing 1 and the second housing 321 are provided with magnets 6, and the magnets 6 of the first housing 1 can be magnetically attracted to the magnets 6 of the second housing 321. When the magnets 6 of the first housing 1 and the magnets 6 of the second housing 321 are magnetically attracted, the first housing 1 and the second housing 321 are connected, the first conductive fixing block 211 contacts the first conductive movable block 222, the second conductive fixing block 311 contacts the second conductive movable block 322, the traction rope 41 is tightened, and both the first elastic element 223 and the second elastic element 323 are compressed.
[0060] More specifically, such as Figure 2 As shown, the second housing 321 also has a receiving cavity. When the magnet 6 of the first housing 1 and the magnet 6 of the second housing 321 are magnetically attracted, the second conductive movable block 322 contacts the second conductive fixed block 311, and the second conductive movable block 322 is received in the receiving cavity. Preferably, as shown... Figure 1 and Figure 2 As shown, the magnet 6 of the first housing 1 is embedded inside the first housing 1; the magnet 6 of the second housing 321 is embedded inside the second housing 321. This arrangement improves the aesthetics of the first housing 1 and the second housing 321, and allows the second conductive movable block 322 to contact the second conductive fixed block 311.
[0061] Specifically, such as Figure 1 and Figure 2 As shown, a second insulating pad 324 is provided on at least the portion of the second housing 321 that contacts the second conductive movable block 322. Since the second conductive movable block 322 is conductive, the second insulating pad 324 is provided to prevent the second housing 321 from becoming conductive, thereby further improving the safety and reliability of the trigger protection device.
[0062] Specifically, a sixth insulating pad is provided on at least the portion of the second elastic member 323 that contacts the second conductive movable block 322. This arrangement further prevents the second housing 321 from becoming energized, thereby further improving the safety and reliability of the trigger protection device.
[0063] Preferably, the second housing 321 is made of metal. This design ensures good structural strength of the second housing 321, and when an external structure impacts the second housing 321, the second housing 321 can protect the second movable end structure 32 located inside it, thereby further improving the safety and reliability of the trigger protection device.
[0064] Preferably, such as Figure 1 and Figure 2As shown, the second movable end structure 32 also includes a second guide post 325. One end of the second guide post 325 is connected to the second conductive movable block 322 along the axial direction, and the other end is slidably connected to the second housing 321. A second elastic member 323 is sleeved on the second guide post 325. The second guide post 325 can guide the second elastic member 323 to extend and retract only along its own extension direction, thereby guiding the second conductive movable block 322 to slide only along the extension direction of the second elastic member 323 on the second housing 321, thereby improving the working performance of the second movable end structure 32.
[0065] Specifically, a seventh insulating layer is provided on at least the portion of the second guide post 325 that contacts the second housing 321 and the second elastic member 323. Alternatively, the second guide post 325 is insulated. This arrangement further prevents the second guide post 325 from becoming energized, thereby further improving the safety and reliability of the trigger protection device.
[0066] Specifically, such as Figure 1 and Figure 2 As shown, the second fixed end structure 31 also includes a connecting plate 312 detachably connected to the first housing 1, and a second conductive fixing block 311 detachably connected to the connecting plate 312. At least the portion of the connecting plate 312 in contact with the second conductive fixing block 311 is provided with a third insulating pad 313. Since the second conductive fixing block 311 is conductive, the third insulating pad 313 is provided to further prevent the first housing 1 from becoming conductive, thereby further improving the safety and reliability of the trigger protection device.
[0067] Specifically, the first conductive fixing block 211 is detachably connected to the first housing 1 by means of threads or the like. The second conductive fixing block 311 is detachably connected to the connecting plate 312 by means of threads or the like.
[0068] More specifically, such as Figure 1 and Figure 2 As shown, the second fixed end structure 31 also includes a second limiting member 52 disposed on the first housing 1, and a connecting plate 312 is distributed between the first limiting member 51 and the second limiting member 52. This arrangement limits the placement positions of the connecting plate 312 and the second conductive fixing block 311.
[0069] This invention also discloses a monitoring and protection method for use in the aforementioned triggering protection device, such as... Figure 1-3 As shown, the monitoring and protection method includes:
[0070] The first housing 1 and the bracket 42 are connected to the protected structure 100 at intervals; the traction rope 41 is wound around the protected structure 100 and placed on the bracket 42, so that the traction rope 41 and the protected structure 100 are distributed at intervals; the second movable end structure 32 is connected to the first housing 1, so that the second fixed end structure 31 is in contact with the second movable end structure 32, the first fixed end structure 21 is in contact with the first movable end structure 22, and the traction rope 41 is taut.
[0071] Real-time determination of whether the first fixed end structure 21 and the first movable end structure 22 are separated; real-time determination of whether the second fixed end structure 31 and the second movable end structure 32 are separated; real-time determination of whether the traction rope 41 is in a taut state.
[0072] If the first fixed end structure 21 separates from the first movable end structure 22; and / or, the second fixed end structure 31 separates from the second movable end structure 32; and / or, the traction rope 41 is not taut, the control will issue an alarm.
[0073] Specifically, the system continuously determines whether the first conductive fixing block 211 and the first conductive movable block 222 are separated; and / or continuously determines whether the second conductive fixing block 311 and the second conductive movable block 322 are separated; and continuously determines whether the traction rope 41 is taut. If the first conductive fixing block 211 and the first conductive movable block 222 are separated; and / or the second conductive fixing block 311 and the second conductive movable block 322 are separated; and / or the traction rope 41 is not taut, the system will issue an alarm.
[0074] Compared to existing technologies, this monitoring and protection method is simpler and effectively improves the monitoring and protection effect.
