[0001] This utility model relates to the technical field of metallurgical lifting and hoisting tools, and in particular to a steel coil lifting hook with an anti-disengagement alarm device. Background Technology

[0002] The steel coil lifting hook with anti-disengagement alarm device is a special lifting equipment and its matching lifting tools designed to meet the special needs of the metallurgical industry for lifting molten metal, large material parts, etc.

[0003] In traditional steel coil lifting hooks with anti-detachment alarm devices, the electronic sensors of traditional anti-detachment structures mostly use fixed thresholds, which cannot adapt to the differentiated safety requirements of steel coils of different weights and specifications. This can easily lead to false alarms and missed alarms. In addition, traditional alarms are directly installed on the outside of the hook, and the electronic components have poor adaptability to the working environment, which may shorten the life of the components. Utility Model Content

[0004] To address the issues of traditional steel coil lifting hooks with anti-disengagement alarm devices being prone to errors when handling steel coils of different weights and specifications, and the alarm devices being easily damaged when installed on the hook, this invention proposes a steel coil lifting hook with an anti-disengagement alarm device. By combining a probe on the hook with a sensor on the boom, the hook's offset angle can be monitored in real time, thereby preventing misjudgments of the possibility of disengagement, significantly improving accuracy and safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel coil lifting hook with an anti-disengagement alarm device, including a connecting and fixing component and an offset monitoring component, wherein the offset monitoring component is located at the bottom of the connecting and fixing component; The offset monitoring component includes a rotating shaft, three probes, and a sensor. The outer surface of the rotating shaft is fitted with a buckle to prevent the lifted steel coil from detaching. The outer surface of the rotating shaft is also fitted with a pull rod to cause the buckle to rotate inward when pulled. A base is fixedly connected to one side of the outer surface of the pull rod, and the base is used to fix the three probes. The tops of the three probes are electrically connected to the bottom arc surface of the sensor.

[0006] Preferably, a buzzer is connected to the circuit on one side of the outer wall of the sensor, and the buzzer is used to issue an alarm sound to remind the user when a large deviation occurs.

[0007] Preferably, an alarm light is also connected to one side of the outer wall of the sensor, and the alarm light is used to flash warning lights to remind the user when a large deviation occurs.

[0008] Preferably, the connecting and fixing assembly includes two side plates, a main shaft is connected through the outer surfaces of the two side plates, and the main shaft is used to connect and fix the two side plates. A roller is sleeved on the outer surface of the main shaft, and the roller is used to reduce rolling friction. A pulley is rotatably connected to the outer surface of the roller.

[0009] Preferably, the connecting and fixing assembly also includes four fixing rods, and the two side plates are connected by the four fixing rods, with fastening bolts threaded to both ends of the four fixing rods.

[0010] Preferably, a connecting shaft is also connected through the outer surfaces of the two side plates, and a hook is inserted into the inner surface of the connecting shaft.

[0011] Preferably, a fixing bolt is fitted on the top of the hook, and the fixing bolt is used to prevent the hook from falling off, and a bearing is rotatably connected to the bottom of the fixing bolt.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by leveraging the coordinated operation of various components of the offset monitoring assembly, an anti-detachment structure is achieved through a pull rod and a buckle during steel coil hoisting operations. A probe at the top of the pull rod is connected to the metal arc surface at the bottom of the sensor. The offset angle of the hook is detected in real time by the movement of the probe. When the offset exceeds a preset value, a buzzer and a warning light connected to the sensor sound an alarm simultaneously. The multi-angle real-time detection between the probe and the sensor can significantly reduce misjudgment of the possibility of hook detachment, avoiding the errors that traditional devices are prone to when dealing with steel coils of different weights and specifications, and the problem that the alarm is easily damaged when installed on the hook. This greatly improves accuracy, effectively balancing practicality and functionality in daily use, and is more suitable for actual needs than the traditional single mode. Attached Figure Description

Each fixing rod 102 is secured at both ends by fastening bolts 103. The main shaft 104 between the two side plates 101 is fitted onto a surface roller 105, causing a pulley 106 to roll with low friction. A connecting shaft 107 also passes through the two side plates 101 below the pulley 106. The connecting shaft 107 contains… The surface-mounted hook 108 is fixed by a fixing bolt 109 secured by a top bolt.

The pull rod 203, connected to the pivot 201, rotates under its own weight, locking the tip of the hook 108 to form an anti-detachment structure. When the rope needs to be removed, simply push the pull rod 203 to rotate the buckle 202 inward, thus creating a notch away from the tip of the hook 108. A base 204 is provided on one side of the pull rod 203, and three probes 205 are provided on the top of the base 204.
