Description
Technical Field
[0001] This utility model belongs to the field of safety rope technology, and in particular relates to a device for detecting the wearing status of a safety rope. Background Technology
[0002] Safety ropes, as indispensable personal protective equipment in high-altitude operations, are of paramount importance. They primarily consist of harnesses worn by the worker and a connecting rope linking the harnesses to a fixed anchor point. Their purpose is to effectively prevent falls in the event of an accident while performing high-altitude tasks, thus ensuring the worker's safety. The quality and performance of safety ropes directly affect the worker's life or death; therefore, rigorous testing and monitoring are crucial.
[0003] However, in existing technological systems, the detection of safety rope wearing status mainly relies on a combination of cameras and image recognition technology. While this method can identify safety ropes to a certain extent, it has revealed a series of significant limitations in practical applications:
[0004] First, in complex and ever-changing environments such as high-altitude operations, light, angles, and the presence of obstructions can all interfere with the camera's shooting effect, thereby affecting the accuracy of image recognition technology and making it difficult for the recognition system to make accurate judgments, thus leading to the risk of misjudgment or missed judgment.
[0005] Secondly, existing image recognition technologies primarily focus on determining whether workers are wearing safety ropes, but struggle to effectively detect the rope's tension. The tension of a safety rope directly affects its protective effectiveness; an overly loose rope may not provide sufficient support in the event of an accident, leading to a fall.
[0006] Therefore, it is essential to invent a device for detecting the wearing status of a safety rope. Utility Model Content
[0007] The purpose of this invention is to provide a device for detecting the wearing status of a safety rope, thereby solving the problems mentioned in the background art.
[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0009] This utility model relates to a device for detecting the wearing status of a safety rope, comprising a bracket, a sliding frame, a first fixing ring, a second fixing ring, limit switches, a gyroscope gravity acceleration sensor, a GPRS module, a power supply, and an auxiliary mechanism. The sliding frame is slidably mounted inside the bracket, with the first fixing ring welded to one end of the bracket and the second fixing ring welded to one end of the sliding frame. The first and second fixing rings are respectively fixed to corresponding safety ropes. Several limit switches are bolted to the inner wall of the bracket, with the detection ends of the limit switches all located on one side of the sliding frame. The gyroscope gravity acceleration sensor, GPRS module, and power supply are bolted to the outer surface of the bracket. The limit switches, gyroscope gravity acceleration sensor, and GPRS module are all connected to a remote computer via a transceiver module. An auxiliary mechanism is fixed between the first and second fixing rings.
[0010] Furthermore, the sliding frame includes a slider, a guide post, a connecting rod, and a spring. The slider is movably disposed inside the support and is slidably connected to the guide post, wherein the guide post is fixed inside the support by welding. A connecting rod is fixed to the side of the slider by welding, wherein the connecting rod slides through the support, and a second fixing ring is fixed to the end of the connecting rod away from the slider by welding. A spring is disposed on the outer side of the connecting rod, wherein the spring is disposed between the lower side of the slider and the inner wall of the support. This arrangement allows the slider to slide accordingly inside the support when the safety rope is pulled.
[0011] Furthermore, the auxiliary mechanism includes a traction belt and a limiting ring. The two ends of the traction belt are respectively fixed to the corresponding first fixed ring and second fixed ring, and the traction belt moves through the limiting ring. The limiting ring is fixed to the outer side of the bracket by bolts. This arrangement can provide an additional connection between the first fixed ring and the second fixed ring.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model, through the cooperation of a sliding frame and a limit switch, allows the slider to slide inside the frame when the safety rope is pulled, thereby making the slider contact the corresponding limit switch. The limit switch can transmit the position of the slider to a remote computer, allowing safety personnel to know the tension of the safety rope by watching the remote computer, so that when the safety rope is fully taut, appropriate measures can be taken in time.
[0014] 2. The gyroscope gravity acceleration sensor and GPRS module of this utility model enable the gyroscope gravity acceleration sensor to detect whether the safety rope is moving in real time and transmit the detected data to a remote computer. This allows safety personnel to know whether the user is wearing the safety rope. Secondly, the GPRS module can detect the position of the safety rope in real time and transmit the detected data to a remote computer.
[0015] 3. The auxiliary mechanism of this utility model can provide an additional connection between the first fixed ring and the second fixed ring, so that when there is a problem with the connection between the bracket and the sliding frame, the traction belt can avoid separation from the two safety ropes of the first fixed ring and the second fixed ring.

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements 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 utility model.
[0024] Please see Figures 1 to 3 As shown, this utility model is a device for detecting the wearing status of a safety rope, including a bracket 1, a sliding frame 2, a first fixing ring 3, a second fixing ring 4, limit switches 5, a gyroscope gravity acceleration sensor 6, a GPRS module 7, a power supply 8, and an auxiliary mechanism 9. The sliding frame 2 is slidably installed inside the bracket 1, wherein one end of the bracket 1 is fixed to the first fixing ring 3 by welding, and one end of the sliding frame 2 is fixed to the second fixing ring 4 by welding; the first fixing ring 3 and the second fixing ring 4 are respectively fixed to the corresponding safety ropes; several limit switches 5 are fixed to the inner wall of the bracket 1 by bolts, wherein the detection end of each limit switch 5 is located on one side of the sliding frame 2; the gyroscope gravity acceleration sensor 6, the GPRS module 7, and the power supply 8 are respectively fixed to the outer side of the bracket 1 by bolts; the limit switches 5, the gyroscope gravity acceleration sensor 6, and the GPRS module 7 are all connected to a remote computer through a transceiver module; the auxiliary mechanism 9 is fixed between the first fixing ring 3 and the second fixing ring 4.
[0025] Specifically, the sliding frame 2 includes a slider 21, a guide post 22, a connecting rod 23, and a spring 24. The slider 21 is movably disposed inside the support 1 and is slidably connected to the guide post 22, wherein the guide post 22 is fixed inside the support 1 by welding. The connecting rod 23 is fixed to the side of the slider 21 by welding, wherein the connecting rod 23 slides through the support 1, and a second fixing ring 4 is fixed to the end of the connecting rod 23 away from the slider 21 by welding. A spring 24 is disposed on the outside of the connecting rod 23, wherein the spring 24 is disposed between the lower side of the slider 21 and the inner wall of the support 1. When the user wears a safety rope and pulls the safety rope, the slider 21 can slide inside the support 1. Furthermore, when the safety rope is in a slack state, the slider 21 can return to its original position under the action of the spring 24.
[0026] Specifically, the auxiliary mechanism 9 includes a traction belt 91 and a limiting ring 92. The two ends of the traction belt 91 are fixed to the corresponding first fixed ring 3 and second fixed ring 4, respectively, and the traction belt 91 moves through the limiting ring 92. The limiting ring 92 is fixed to the outer side of the bracket 1 by bolts. When in use, the traction belt 91 connects the first fixed ring 3 and the second fixed ring 4. Thus, when there is a problem with the connection between the bracket 1 and the sliding frame 2, the traction belt 91 can prevent the two safety ropes of the first fixed ring 3 and the second fixed ring 4 from separating.
[0027] Please see Figure 1-3 As shown, this utility model is a device for detecting the wearing status of a safety rope. Its working principle is as follows: During installation, the first fixing ring 3 and the second fixing ring 4 are respectively fixed to the strap worn on the body and the connecting rope between the strap and the hanging node. During use, the gyroscope gravity acceleration sensor 6 can detect whether the safety rope is being worn (after wearing the safety rope, this device will shake with the wearer's movements; if the gyroscope gravity acceleration sensor 6 detects shaking, it indicates the rope is being worn; otherwise, it indicates it is not being worn). The GPRS module 7 can detect the wearer's position. Furthermore, when the safety rope is pulled, the slider 21 can slide inside the bracket 1, causing the slider 21 to contact the corresponding limit switch 5. The limit switch 5 can transmit the position of the slider 21 to a remote computer. Safety personnel can monitor the tension of the safety rope by viewing the remote computer, and thus take timely measures when the safety rope is fully taut.
