Description

Technical Field

[0001] This utility model relates to a full-process skip hook monitoring device, belonging to the field of mining equipment technology. Background Technology

[0002] Mine hoists are important transportation equipment in mines. Most main shaft hoists use skip hoisting. The hooks on both sides of the skip are self-protection devices. When the skip enters the unloading station rail, the fixed wheel and guide wheel cause the skip hooks to disengage, allowing the bottom of the skip to open smoothly and complete the unloading. When the skip leaves the unloading station rail, the skip hooks re-engage, ensuring the safe and stable operation of the skip throughout the entire process of going down, loading, and going up.

[0003] The skip hook of a hoist must be securely attached to the limit block during the downward, loading, and upward movements. Otherwise, if the skip hook detaches, material can easily spill, causing damage to the wire rope and shaft equipment, posing a significant safety risk to the hoist operation. Accurate monitoring of the skip hook has always been a challenge in the industry. Some existing main shaft hoists do not monitor the status of the skip hook, while others only monitor it within a small area of ​​the straight rail at the unloading station. None of these systems achieve full-process skip hook monitoring and alarm functionality, or interlocking with the hoist's operating signals. Summary of the Invention

[0004] The purpose of this invention is to provide a full-process skip hook monitoring device. By detecting the displacement of the hook head from the displacement switch, it determines whether the hook head is effectively hooked on the limit block and transmits the displacement to the hoisting electrical control system. This achieves full-process monitoring of the skip hook status, effectively preventing material spillage in the skip due to improper hook engagement, which could damage the tail rope and shaft equipment. This ensures the safe and reliable operation of the hoisting system and solves the aforementioned problems in the background technology.

[0005] The technical solution of this utility model is: a full-process skip hook monitoring device, comprising a skip hook, a limit block, a hook head, a displacement switch, a signal cable, a transmitting device, and a wellhead receiving device. The hook head is located at the front end of the skip hook and is locked onto the limit block, locking the skip body. The displacement switch is located directly below the hook head in the locked state. The displacement switch is connected to the transmitting device via a signal cable, and the transmitting device is signal-connected to the wellhead receiving device. The transmitting device is signal-connected to the wellhead receiving device via a wireless TCP / IP protocol and is installed on the top of the skip. The wellhead receiving device is signal-connected to the hoisting electrical control system and is installed in the wellhead unloading station control room.

[0006] The displacement switch is located directly below the hook head in the locked state, and its installation position is perpendicular to the hook head.

[0007] The transmitting device 6 includes a transmitting antenna, a wireless transmitting module, a data acquisition module, and a power supply module connected in sequence. The power supply module inside the transmitting device supplies power to the equipment inside the transmitting device and provides working power to the displacement switch through a signal cable. The displacement switch detects the displacement signal and transmits it to the data acquisition module through the signal cable. The data acquisition module transmits the value of the displacement switch to the wireless transmitting module. The wireless transmitting module transmits it to the wellhead receiving device through the wireless TCP / IP protocol.

[0008] The wellhead receiving device includes a receiving antenna, a wireless receiving module, and an AI module connected in sequence. The wireless receiving module transmits the received wireless transmission module signal to the AI ​​module, and simultaneously transmits it to the hoisting control system for display and interlocking.

[0009] The limiting block and the hook head have mutually matching and fixed contact surfaces.

[0010] The wireless transmitting module 7, data acquisition module 8, wireless receiving module 10, AI module 11, wellhead unloading station operation room 16, and hoisting electrical control system 17 involved in this utility model are all technologies known and commonly used in the field.

[0011] The beneficial effects of this utility model are: by detecting the displacement of the hook head from the displacement switch, it can be determined whether the hook head is effectively hooked on the limit block, and the displacement is transmitted to the hoisting electric control system, realizing full-process monitoring of the skip hook status, effectively avoiding the spillage of materials in the skip due to the skip hook not being properly hooked, thereby causing damage to the tail rope and shaft equipment, and ensuring the safe and reliable operation of the hoisting system.

The hook head 3 at the front end of the skip hook 1 locks the skip box body by overlapping with the limiting block 2. The displacement switch 4 is located directly below the hook head 3 in the locked state and detects the displacement of the hook head 3 from the top of the displacement switch 4.
