Technical Field

[0001] The present invention relates to the technical field of high-altitude construction safety protection, and particularly to a safety monitoring device and a high-altitude operation rope system. Background Art

[0002] When working at high altitudes, fixed suspension points, safety ropes, and safety belts worn on the operators are usually used to ensure the safety of the operators. Specifically, the safety rope can be connected to the personnel buckle on the safety belt through the suspension point. Once the operator slips, the safety rope can use the suspension point as a fulcrum to pull the personnel buckle, so that the safety belt can support the operator and prevent the operator from falling directly to the ground and being injured. Therefore, the safety rope is the lifeline of the operator in on-site high-altitude operations, and its correct suspension plays a crucial role.

[0003] Among them, during the use of the safety rope, it is required to "hang high and use low", that is, the end of the safety rope connected to the suspension point needs to be higher than the end of the safety rope connected to the personnel buckle, in order to prevent additional injuries to the waist and back of the personnel that may be caused by incorrect suspension when a personnel falls.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] For high-altitude operations, safety ropes are one of the important protective equipment for protecting the personal safety of high-altitude operators. Correct installation of safety ropes and monitoring of the state of safety ropes are important measures to prevent the fall and casualty accidents of on-site high-altitude operators. Among them, the installation method / installation state of "hanging high and using low" of the safety rope can effectively reduce the degree of injury when a person falls. In the related art, there is a lack of detection of the installation method / installation state of "hanging high and using low" of the safety rope.

[0041] In view of this, the present invention provides a safety monitoring device and a high-altitude operation rope system for monitoring whether the safety rope is installed in the manner of "hanging high and using low" to reduce the occurrence of serious injuries to personnel when a person falls.

[0042] As Figure 1 and Figure 2 shown, the high-altitude operation rope system provided by the embodiment of the present invention includes a safety monitoring device 100 and a safety rope 200. The safety monitoring device 100 is used to monitor the installation state of the safety rope 200. By monitoring the installation state of the safety rope 200 through the safety monitoring device 100, high-altitude operators are reminded to install the safety rope 200 in the manner of "hanging high and using low" to reduce the degree of injury when the operator falls.

[0043] Please refer to Figure 2 , the safety rope 200 includes a third end 201 and a fourth end 202 which are oppositely arranged. The third end 201 is used to connect to the suspension point, and the fourth end 202 is used to connect to the personnel buckle. The suspension point can be located near the high-altitude operation position, and the personnel buckle can be located on objects such as the safety belt, waist belt, and protective gear worn by the operator, such as the D-ring on the back or the waist of the safety belt. When the operator falls from a high altitude, one end of the safety rope 200 connected to the suspension point is fixed, so that the safety rope 200 can prevent the operator from falling by pulling the personnel buckle, avoiding the operator being injured by falling to the ground.

[0044] Please refer to Figure 1 and Figure 2, the safety monitoring device 100 includes an alarm mechanism 10, a first monitoring mechanism 20 and a processor 30. The processor 30 is electrically connected to the alarm mechanism 10 and the first monitoring mechanism 20. The first monitoring mechanism 20 is used to monitor the installation state of the safety rope 200 and send a monitoring signal to the processor 30. The processor 30 determines whether the safety rope 200 is installed in the "high suspension and low use" manner according to the monitoring signal. If not, it controls the alarm mechanism 10 to give an alarm, so as to remind the high-altitude operators to adjust the installation of the safety rope 200.

[0045] Please refer to Figure 2 and Figure 3 , the first monitoring mechanism 20 includes a hose 21, a solid fluid 22 and a first sensor 23. The hose 21 has a first end 211 and a second end 212 which are oppositely arranged. The first end 211 is used to connect to one end of the safety rope 200 connected to the suspension point, and the second end 212 is used to connect to one end of the safety rope 200 connected to the personnel buckle. That is, the first end 211 of the hose 21 is connected to the third end 201 of the safety rope 200, and the second end 212 of the hose 21 is connected to the fourth end 202 of the safety rope 200.

[0046] In specific implementation, the safety rope 200 includes a rope body 203, a first hook 204 and a second hook 205. The first hook 204 and the second hook 205 are respectively connected to both ends of the rope body 203. Among them, the first hook 204 is located at the third end 201 of the safety rope 200 and is used to connect to the suspension point, and the second hook 205 is located at the fourth end 202 of the safety rope 200 and is used to connect to the personnel buckle. The first end 211 of the hose 21 can be connected to the first hook 204 or to the end of the rope body 203 connected to the first hook 204; the second end 212 of the hose 21 can be connected to the second hook 205 or to the end of the rope body 203 connected to the second hook 205.

[0047] Among them, the length of the hose 21 can be the same as the length of the rope body 203 or greater than the length of the rope body 203. The first monitoring mechanism 20 can be adapted to different types of safety ropes 200, has better versatility, and users can directly configure the first monitoring mechanism 20 for the original safety rope 200 without discarding the original safety rope 200, greatly saving costs.

[0048] Please refer to Figures 3 to 5 , the solid fluid 22 is placed in the hose 21 and can flow between the first end 211 and the second end 212. The solid fluid 22 is configured to be lower than the first end 211 and the second end 212 when the first end 211 and the second end 212 are flush, and when there is a height difference between the first end 211 and the second end 212, it flows to the lower end of the first end 211 and the second end 212. Among them, Figure 3It is a state diagram of the hose 21 when the first end 211 and the second end 212 are flush. Figure 4 It is a state diagram of the hose 21 when the first end 211 is higher than the second end 212. Figure 5 It is a state diagram of the hose 21 when the first end 211 is lower than the second end 212.

[0049] The first sensor 23 is connected to the first end 211 or the second end 212. The first sensor 23 is used to emit a first signal when contacting with the solid fluid 22.

[0050] In a specific application, when the first end 211 and the second end 212 of the safety rope 200 are at the same height, the solid fluid 22 is lower than the first end 211 and the second end 212 and does not contact the first sensor 23 connected to the first end 211 or the second end 212, and the first sensor 23 does not emit a first signal; when there is a height difference between the first end 211 and the second end 212 of the safety rope 200, the solid fluid 22 flows to the lower end of the first end 211 and the second end 212. If the first sensor 23 is connected to the lower end at this time, the solid fluid 22 contacts the first sensor 23 and the first sensor 23 emits a first signal. If the first sensor 23 is connected to the higher end at this time, the solid fluid 22 does not contact the first sensor 23 and the first sensor 23 does not emit a first signal.

[0051] By arranging the solid fluid 22 in the hose 21, compared with arranging a liquid fluid in the hose 21, the requirement for the sealing performance of the hose 21 can be reduced, and the production of the hose 21 and the assembly efficiency with other components (such as the first sensor 23) can be accelerated. Connecting the first sensor 23 to the first end 211 or the second end 212 of the hose 21, and the first end 211 and the second end 212 are located at the ends of the hose 21, which is convenient for the installation of the first sensor 23 and accelerates the assembly efficiency of the first sensor 23 and the hose 21. Therefore, the safety monitoring device 100 provided by the present invention is beneficial to improving the production efficiency of the first monitoring mechanism 20.

[0052] In an embodiment, the processor 30 is electrically connected to the first sensor 23 and the alarm mechanism 10. The processor 30 is used to receive the first signal to judge whether there is an abnormal height difference between the first end 211 and the second end 212. If so, it controls the alarm mechanism 10 to give an alarm. Among them, the first signal is the above-mentioned monitoring signal.

[0053] The processor 30 can receive a first signal and can determine whether there is an abnormal height difference between the first end 211 and the second end 212. In a specific application, the processor 30 can be configured to determine that there is an abnormal height difference between the first end 211 and the second end 212 when receiving the first signal, or can be configured to determine that there is no abnormal height difference between the first end 211 and the second end 212 when receiving the first signal.

[0054] When the processor 30 determines that there is an abnormal height difference between the first end 211 and the second end 212, the safety rope 200 is not installed in the way of "hanging high and using low". At this time, the processor 30 controls the alarm mechanism 10 to alarm; when the processor 30 determines that there is no abnormal height difference between the first end 211 and the second end 212, the safety rope 200 is installed in the way of "hanging high and using low". At this time, the processor 30 controls the alarm mechanism 10 not to alarm. In this way, the monitoring of whether the safety rope 200 is installed in the way of "hanging high and using low" is realized.

[0055] Among them, the abnormal height difference between the first end 211 and the second end 212 can be set such that the first end 211 is lower than the second end 212, and the abnormal height difference between the first end 211 and the second end 212 can also be set such that the first end 211 is lower than the second end 212 and the first end 211 is flush with the second end 212.

[0056] In an embodiment, please refer to Figures 3 to 5 , the first sensor 23 is connected to the first end 211. When the processor 30 receives the first signal, it determines that there is an abnormal height difference between the first end 211 and the second end 212. In this technical solution, the abnormal height difference between the first end 211 and the second end 212 is that the first end 211 is lower than the second end 212.

[0057] In a specific application, please refer to Figure 3 , when the first end 211 and the second end 212 are flush, the solid fluid 22 is lower than the first end 211 and the second end 212 and does not contact the first sensor 23 located at the first end 211, and the first sensor 23 does not emit the first signal. Please refer to Figure 4 , when the first end 211 is higher than the second end 212, the solid fluid 22 flows to the second end 212 and does not contact the first sensor 23 located at the first end 211, and the first sensor 23 does not emit the first signal. Please refer to Figure 5 , when the first end 211 is lower than the second end 212, the solid fluid 22 flows to the first end 211, contacts the first sensor 23 located at the first end 211, the first sensor 23 emits the first signal. When the processor 30 receives the first signal, it determines that there is an abnormal height difference between the first end 211 and the second end 212 and controls the alarm mechanism 10 to alarm.

[0058] In another embodiment, the first sensor 23 is connected to the second end 212. When the processor 30 receives the first signal, it determines that there is no abnormal height difference between the first end 211 and the second end 212. When the processor 30 does not receive the first signal within a preset time, it determines that there is an abnormal height difference between the first end 211 and the second end 212. In this technical solution, the abnormal height difference between the first end 211 and the second end 212 is that the first end 211 is lower than the second end 212 and the first end 211 is flush with the second end 212. For ease of description, the preset time in this technical solution is defined as the first preset time, that is, when the processor 30 does not receive the first signal within the first preset time, it determines that there is an abnormal height difference between the first end 211 and the second end 212. The first preset time can be 1S or 2S or 10S or 30S. It should be noted that the first preset time is not limited here.

[0059] In a specific application, when the first end 211 and the second end 212 are flush, the solid fluid 22 is lower than the first end 211 and the second end 212 and does not contact the first sensor 23 located at the second end 212. The first sensor 23 does not emit the first signal. When the processor 30 does not receive the first signal within the preset time, it determines that there is an abnormal height difference between the first end 211 and the second end 212 and controls the alarm mechanism 10 to alarm. When the first end 211 is lower than the second end 212, the solid fluid 22 flows to the first end 211 and does not contact the first sensor 23 located at the second end 212. The first sensor 23 does not emit the first signal. When the processor 30 does not receive the first signal within the preset time, it determines that there is an abnormal height difference between the first end 211 and the second end 212 and controls the alarm mechanism 10 to alarm. When the first end 211 is higher than the second end 212, the solid fluid 22 flows to the second end 212 and contacts the first sensor 23 located at the second end 212. The first sensor 23 emits the first signal. When the processor 30 receives the first signal, it determines that there is no abnormal height difference between the first end 211 and the second end 212, and at this time the alarm mechanism 10 does not alarm.

[0060] In one embodiment, the solid fluid 22 is made of a metal material or made of a metal material and a non - metal material. The first sensor 23 is a metal sensor, and the metal sensor is used to emit the first signal when contacting the solid fluid 22. Setting the solid fluid 22 to be made of a metal material or made of a metal material and a non - metal material, at least part of the material forming the solid fluid 22 is a metal material, which is beneficial for the metal sensor to emit the first signal when contacting the solid fluid 22. The metal sensor has a high - sensitivity electromagnetic response characteristic to the metal material, which can significantly improve the detection reliability.

[0061] Of course, in specific applications, as an alternative technical solution, the first sensor 23 can also be set as other types of sensors, such as a pressure sensor. Or, as another alternative technical solution, the solid fluid 22 can be made of a non-metallic material, and the first sensor 23 is of other types, such as the solid fluid 22 is made of plastic material and the first sensor 23 is a capacitive contact sensor.

[0062] In one embodiment, the solid fluid 22 includes a plurality of spherical particles. Since the spheres have good fluidity, setting the solid fluid to include a plurality of spherical particles is beneficial to the flow of the solid fluid 22 in the hose 21 and improves the flow performance of the solid fluid 22. It can be understood that in other embodiments, the solid fluid 22 can also include a plurality of particles of other shapes, such as cubes.

[0063] In one embodiment, the solid fluid 22 includes a plurality of solid particles. Setting the solid fluid 22 as solid particles, the solid particles are heavy, which can ensure that the solid fluid flows downward under the action of gravity to ensure the accuracy of detection. Of course, in other embodiments, the solid fluid 22 can also be set to include a plurality of hollow particles. Adopting this technical solution, the hollow particles help to reduce the weight of the solid fluid 22 and facilitate the carrying by high-altitude operators.

[0064] In this embodiment, the solid fluid 22 includes a plurality of solid steel balls, which on the one hand is beneficial for the metal sensor to emit the first signal, and on the other hand helps the solid fluid 22 to flow in the hose 21. Of course, in other embodiments, the solid fluid 22 can also include a plurality of hollow steel balls.

[0065] Please refer to Figure 1 and Figure 2 , the safety monitoring device 100 further includes a second monitoring mechanism 40. The second monitoring mechanism 40 is used to connect to one end of the safety rope 200 connected to the suspension point, that is, the second monitoring mechanism 40 is connected to the third end 201 of the safety rope 200. The second monitoring mechanism 40 includes a second sensor 41. The second sensor 41 is used to emit a second signal when detecting that the safety rope 200 is connected to the suspension point. The processor 30 is also electrically connected to the second sensor 41 and is used to receive the second signal to judge whether the safety rope 200 is connected to the suspension point. If not, the alarm mechanism 10 is controlled to alarm.

[0066] In a specific application, when the processor 30 receives the second signal, it determines that the safety rope 200 is connected to the suspension point, and the alarm mechanism 10 does not alarm; when the processor 30 does not receive the second signal within a preset time, it determines that the safety rope 200 is not connected to the suspension point, and controls the alarm mechanism 10 to alarm. In this way, the safety monitoring device 100 can monitor whether the safety rope 200 is connected to the suspension point. For the convenience of description, the preset time in this technical solution is defined as the second preset time, that is, when the processor 30 does not receive the second signal within the second preset time, it determines that the safety rope 200 is not connected to the suspension point. The second preset time can be 1S, 2S, 10S, or 30S. It should be noted that the second preset time is not limited here.

[0067] In an embodiment, the second sensor 41 is a metal sensor. Generally, the suspension point is set on a metal bracket. By setting the second sensor 41 as a metal sensor, it can detect whether the third end 201 of the safety rope 200 is connected to the metal bracket, so as to determine whether the safety rope 200 is connected to the suspension point.

[0068] In another embodiment, the second sensor 41 is a photoelectric proximity sensor. In some occasions, the suspension point is set on a non-metal bracket. By setting the second sensor 41 as a photoelectric proximity sensor, it can detect whether the third end 201 of the safety rope 200 is connected to the non-metal bracket, so as to determine whether the safety rope 200 is connected to the suspension point.

[0069] In another embodiment, two second sensors 41 are provided, one second sensor 41 is a metal sensor, and the other second sensor 41 is a photoelectric proximity sensor. In this way, no matter whether the suspension point is set on a metal bracket or a non-metal bracket, detection can be carried out.

[0070] It can be understood that in other embodiments, the second sensor 41 can also be other types of sensors, such as a pressure sensor.

[0071] In an embodiment, the second sensor 41 is connected to the top of the first hook 204. Here, the top of the first hook 204 refers to the end of the first hook 204 away from the rope body 203. Specifically, the second sensor 41 is connected to one side of the top of the first hook 204. When the first hook 204 is hung on the suspension point, the top of the first hook 204 contacts the suspension point (metal bracket). By setting the second sensor 41 on one side of the top of the first hook 204, when the top of the first hook 204 contacts the suspension point (metal bracket), the second sensor 41 can contact the suspension point, which helps to improve the accuracy of the second sensor 41 in monitoring.

[0072] In one embodiment, when the processor 30 determines that the safety rope 200 is not connected to the suspension point, it controls the alarm mechanism 10 to alarm after a preset time. For ease of description, the preset time in this technical solution is defined as the third preset time, that is, when the processor 30 determines that the safety rope 200 is not connected to the suspension point, it controls the alarm mechanism 10 to alarm after the third preset time. The third preset time can be 1S, 2S, 10S, or 30S. It should be noted that the third preset time is not limited here. By setting the control for the alarm mechanism 10 to alarm after the third preset time, false alarms caused by vibrations and other reasons can be avoided.

[0073] Please refer to Figure 1 , the alarm mechanism 10 includes a first alarm 11 and a second alarm 12, and the processor 30 is used to control the first alarm 11 and the second alarm 12 to alarm simultaneously. In a specific application, the first alarm 11 is placed on the high-altitude operator and can remind the high-altitude operator through vibration or beeping, etc.; the second alarm 12 is placed on the ground control personnel and can remind the ground control personnel through flashing lights, etc., and then the ground control personnel remind the high-altitude operator.

[0074] In one embodiment, the high-altitude work rope system further includes a mobile terminal (not shown in the figure), and the second alarm 12 is integrated into the mobile terminal. The ground control personnel monitor and remind the high-altitude operators through the mobile terminal.

[0075] In one embodiment, the same second alarm 12 can receive signals from multiple processors 30. In this way, multiple processors 30 can control the same second alarm 12 to alarm, and the ground control personnel can manage multiple safety ropes 200 simultaneously. In this embodiment, the same second alarm 12 can receive signals from eight processors 30, that is to say, the ground control personnel can monitor the installation status of eight safety ropes 200 at the same time.

[0076] In one embodiment, the hose 21 is detachably connected to the safety rope 200. In this way, when the first monitoring mechanism 20 or the safety rope 200 is damaged, only the first monitoring mechanism 20 or the safety rope 200 needs to be replaced, and there is no need to replace the high-altitude work rope system, saving costs. Of course, in a specific application, as an alternative implementation, the hose 21 can also be fixedly connected to the safety rope 200.

[0077] During specific implementation, the hose 21 can be connected to the safety rope 200 through Velcro or through a buckle. Not only the first end 211 and the second end 212 of the hose 21 are respectively connected to the safety rope 200, but other parts (such as the middle part) of the hose 21 can also be connected to the safety rope 200.

[0078] The above are only the preferred embodiments of the present invention, and do not thereby limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present invention.
