[0023] like Figure 1-2 As shown, a monitoring controller 10 is fixedly connected to one side of the tractor 7, and a power supply 12 is also provided inside the tractor 7, and indicator lights 11 are provided on both sides of the power supply 12;

[0024] In this embodiment, by such a configuration, the device can effectively improve the overall safety of the device through the configuration of the device when it is in use, and the engagement of the housing 1 can also be monitored all the time when it is in use.

[0025] like Figure 1-2 As shown, the output end of the power supply 12 is electrically connected to the input end of the indicator light 11, the indicator light 11 is also electrically connected to the monitoring controller 10, and the input end of the monitoring controller 10 is electrically connected to the input end of the power supply 12;

[0026] In this embodiment, such an arrangement is adopted to ensure the combined use of the power supply 12 , the indicator light 11 , and the monitoring controller 10 .

[0027] like Figure 1-2 As shown, the surface of the rope 13 also passes through a limit card 14, and a through hole 15 is provided inside the limit card 14. The through hole 15 is provided to fix the penetration position of the rope 13;

[0028] In this embodiment, by such an arrangement, the device can be effectively fixed when in use, thereby ensuring the practicality of the rope 13 for personnel.

[0029] like Figure 1-2 As shown, a rope clamp 16 is also provided on the surface of the limit clamp 14, a tightening block 17 is provided on the top of the rope clamp 16, a connecting rope 18 is provided on the surface of the tightening block 17, a rotatable limit lock 19 is also provided at the bottom of the connecting rope 18, and the bottom of the rope 13 is fixedly connected to the limit base 20;

[0030] In this embodiment, by such an arrangement, the device can be effectively arranged through the arrangement of the above device when in practical use, and then it can be clamped and fixed, so that the device can ensure the safety and stability of the user.

[0031] like Figure 1-2 As shown, a detection method for a multifunctional safety protection device installed in a subway comprises the following steps:

[0032] S1, the restricted use site of the device may have a tunnel or a semi-sealed site that is not connected to the outside world. At this time, when we use the device, we can install the power supply 12. The switch of the power supply 12 is set on the side close to the handle 8. When the handle 8 is pressed down to ensure that the card board 2 is completely gathered inside the shell 1, the shell 1 has the smallest area. At the same time, the handle 8 sinks to the bottom and reaches the top contact surface of the power supply 12, so that the power supply 12 starts to start, and then supplies power to the indicator light 11 and the monitoring controller 10;

[0033] S2, when the indicator light 11 is powered, a green light column will appear, and there are two light groups inside, namely a green light group and a red light group. One of the two is activated and controlled by the internal processor, and the red light group is activated first. When the monitoring controller 10 is powered, it will conduct electromagnetic wave survey through its side close to the tractor 7, and the refraction length and frequency of the electromagnetic wave will be used as the priority control conditions to monitor the traction rope 6;

[0034] S3, during the monitoring process, the device as a whole should be in use, the prerequisite is that the housing 1 and the card plate 2 are both engaged in the gap, and special attention should be paid to whether the initial insertion position is loose. When the electromagnetic wave generates interference or is no longer stable, the monitoring controller 10 will immediately turn on the connection between the indicator light 11 and the monitoring controller 10, so that the indicator light 11 starts to flash red, and thus warns the user to suspend the operation and readjust the fixed position of the housing 1, so as to achieve the safety warning function of the device;

[0035] Working principle:

[0036] Pull the tractor 7 to retract the two-sided card plates 2, so that the shell 1 is reduced in size and enters the gap. After the card plates 2 are released, the card plates 2 are pushed out by the springs 4, so that the shell 1 is stuck to the wall structure to form resistance. Pulling the rope 13 will only make the card plates 2 slide outward, causing the shell 1 to expand in size and create anchoring force. After the operation is completed, it is only necessary to pull the tractor 7 to retract the card plates 2 to reduce the size of the shell 1 so that it can be easily taken out. The end of the shell 1 uses a limit card 14 to form a closed loop with the rope 13, which can be firmly stuck at the position to be fixed. First adjust the required The length of the fixed rope 13 can be reserved for the working length of the safety belt. After the rope 13 is tightened to fix the object, the rope 13 is wrapped around the fixed object for a circle and then inserted into the rope clamp 16. The rope clamp 16 is closed by the rotatable limit lock 19, and the rotatable limit lock 19 is tightened to firmly fix it. It is simple and convenient. In the process of using it, especially when the device is clamped on the wall, when the handle 8 is pressed down to ensure that the card plate 2 is completely gathered inside the shell 1, the shell 1 has the smallest area at this time. At the same time, the handle 8 sinks to The bottom reaches the top connection surface of the power supply 12, so that the power supply 12 starts to start, and then supplies power to the indicator light 11 and the monitoring controller 10; when the indicator light 11 is powered on, a green light column will appear, and there are two light groups inside, namely a green light combination and a red light group. Either of them is started and controlled by the internal processor, and the red light group is started first. When the monitoring controller 10 is powered on, it will conduct electromagnetic wave survey through its side close to the traction device 7, and the refraction length and frequency of the electromagnetic wave will be used as the priority control conditions to monitor the traction rope 6; during the monitoring process, the device as a whole should be in use, and the prerequisite is that the shell 1 and the card plate 2 are both engaged in the gap. Special attention should be paid to whether the initial insertion position is loose. When the electromagnetic wave generates interference or is no longer stable, the monitoring controller 10 will immediately open the connection between the indicator light 11 and it, so that the indicator light 11 starts to flash red, and thereby warns the user to suspend the operation and readjust the fixed position of the shell 1, so as to achieve the safety warning function of the device.

[0037] When testing, what is tested is whether it is stable. As long as the internal rope is in a stable pressure state, it will not fluctuate. If the internal traction rope breaks or gradually collapses, the internal part can detect unstable electromagnetic waves, which will enable it to switch the power light to warn.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
