Technical Field
[0001] This utility model relates to the field of safety rope hook technology, specifically a safety rope hook for real-time monitoring of the unattached state. Background Technology
[0002] The hook is an important component of the safety rope. It is generally made of high-strength metal casting and usually has a self-locking feature. When in use, the hook is firmly attached to a high safety anchor point nearby. The safety rope is an auxiliary rope woven from synthetic fibers. It is usually used in conjunction with other safety equipment such as safety belts and self-locking devices to ensure comprehensive safety protection. In engineering construction, there are often high-altitude operations such as scaffolding erection and dismantling. High-altitude operations refer to operations carried out at a height of more than two meters. The most important concern in high-altitude operations is safety, mainly to prevent falls from height. Safety ropes are very important in high-altitude operations, and construction workers are required to wear them.

[0031] A power switch 16 is installed on the outer wall of the smart host 15, and an SOS alarm button 17 is installed on the outer wall of the smart host 15 below the power switch 16.
[0032] The smart host 15 has a speaker 21 installed inside, and a lithium battery 20 is installed inside the smart host 15 below the speaker 21.
[0033] The safety rope assembly 22 is provided with a nylon protective sleeve 24 on the outside, and the safety rope 25, the positive A conductor 7 and the negative B conductor 10 are provided inside the nylon protective sleeve 24.
[0034] The negative B conductor 10 on the negative B contact 8 side extends to the tail end of the D-type hook 1, and the positive A conductor 7 on the positive A contact 5 side extends to the tail end of the D-type hook 1. The positive A conductor 7 and the negative B conductor 10 extend into the interior of the nylon protective sleeve 24. The surfaces of the positive A conductor 7 and the positive B conductor 10 are fitted with stainless steel spring protective tubes, which serve to protect the conductors from external impact damage.

The input terminal of the controller 19 is electrically connected to the output terminals of the power switch 16, the SOS alarm button 17, and the lithium battery 20. The output terminal of the controller 19 is electrically connected to the input terminal of the horn 21.
[0036] One end of the nylon protective sleeve 24 is equipped with a hook and loop fastener 23, and the hook and loop fastener 23 is fixedly connected to the nylon protective sleeve 24. The other end of the nylon protective sleeve 24 is equipped with a hook and loop fastener 18, and the hook and loop fastener 18 is fixedly connected to the nylon protective sleeve 24.
[0037] Using contact spring technology, the positive A wire 7 and the negative B wire 10 are led to the controller 19, and then form a circuit through the positive A contact 5, the negative A contact 4, the D-type hook 1, the positive B contact 9, and the negative B contact 8. The A contact and the B contact become switches A and B connected in series in the circuit, respectively. The state of the hook is determined by the opening and closing of the circuit.
[0038] Type 1: Hook is suspended without load. At this time, negative A contact 4 and positive A contact 5 are in contact, D-type hook 1 is in contact with hook lock 6 and the lock is closed. Switch A is closed, the spring strip 3 is not squeezed by external force and rebounds normally, causing negative B contact 8 and positive B contact 9 to contact, switch B is closed, the circuit is closed, and the alarm is triggered.
[0039] The second type: When the hook is normally engaged, the negative A contact 4 and the positive A contact 5 are in contact, the D-type hook 1 is in contact with the hook lock 6 and the lock is closed, the switch A is closed, the upper part of the spring strip 3 is close to the D-type hook 1, and the spring sheet 26 is squeezed. The spring strip 3 drives the stop block 13 to rotate around the hinge shaft 14, so that the negative B contact 8 and the positive B contact 9 are not in contact, the switch B is open, the circuit is open, it is judged to be a normal working state, and there is no alarm.
[0040] The third type: hook transfer attachment point. At this time, the D-type hook 1 is in contact with the hook lock 6 and the lock is disconnected. The negative A contact 4 and the positive A contact 5 are not in contact. The switch A is open. The spring strip 3 is not squeezed by external force. The negative B contact 8 and the positive B contact 9 are in contact. The switch B is closed. The circuit is open. It is judged to be a normal working state and no alarm is triggered.
[0041] The fourth type: When the hook is moved to the anchor point, the hook buckle is at the anchor point. At this time, the D-type hook 1 is in contact with the hook lock 6 and the lock is broken. The negative A contact 4 and the positive A contact 5 are not in contact. Switch A is turned off. The upper part of the spring strip 3 is close to the D-type hook 1, which squeezes the spring sheet 26. The spring strip 3 drives the stop block 13 to rotate around the hinge shaft 14, so that the negative B contact 8 and the positive B contact 9 are not in contact. The circuit is open. It is judged to be a normal working state and no alarm is triggered.
[0042] The positive A conductor 7, the negative B conductor 10, and the safety rope 25 are wrapped by a nylon protective sleeve 24. The hook and loop sides 23 and 18 of the Velcro fastener work together to tighten the nylon protective sleeve 24. The rope assembly 22 is connected to the external five-point safety belt.
[0043] The speaker 21 is used for convenient alarms. The intelligent host 15 sends alarm information to the WEB and APP terminals of the smart construction site platform through the internal network module. The alarm content is displayed in a prominent position on the interface and an alarm record is generated. The intelligent host 15 is equipped with an SOS alarm button 17. If a fall occurs during work and self-rescue is impossible, pressing the SOS alarm button 17 will send an alarm information. This can prevent dangerous situations caused by users intentionally or unintentionally not attaching or loosening the hook during operation, reduce safety risks, and prevent problems before they occur from the outset. It solves the most common safety hazards in the field of high-altitude operation safety management, such as not attaching the safety rope or the safety rope being loose, and ensures personal safety. It has great social significance and commercial value.
