Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of intelligent tank chain doors for mining, and specifically relates to intelligent tank chain doors for mining. Background Technology
[0002] The intelligent mine cage door is a device specifically designed for underground mine cage hoisting systems. It is mainly installed at the cage inlet and outlet to replace the traditional manual operation of the cage curtain door, realizing automated opening and closing control of the cage curtain door to improve mine hoisting efficiency and safety.
[0003] When the tank curtain door needs to be opened, the operator issues an opening command via wireless control. Upon receiving the command, the PLC program control system sends a signal to the drive mechanism (such as a motor or hydraulic control system), initiating its operation. The motor rotates forward, or the hydraulic pump delivers hydraulic oil to the cylinder, causing the piston within the cylinder to move. This power is transmitted to the door stop mechanism via a transmission mechanism, causing the bottom lever of the door stop mechanism to move upward, folding the entire tank curtain door upward. When the tank curtain door needs to be closed, the operator issues a closing command. The motor reverses, or the hydraulic oil in the cylinder flows back, causing the door to fall under its own weight or with the pulling force of the cylinder, closing the entire tank curtain door downward. Throughout the entire process, the PLC program control system monitors the equipment's operating status in real time to ensure the door is accurately positioned and handles any abnormalities promptly.
[0004] Specifically, in the actual operation of intelligent mine chain gates, the opening action mainly relies on two power methods: motor drive or cylinder drive. The motor outputs torque through forward rotation, or the cylinder generates thrust by pushing a piston with hydraulic oil. This power is transmitted through chains, wire ropes, and other transmission components to the bottom stop bar of the gate mechanism, causing the stop bar to lift upwards. This, in turn, drives the entire chain gate, composed of multiple high-strength stainless steel horizontal bars and vertical chains, to fold upwards, ultimately achieving smooth opening of the gate. However, this automated drive mode has significant limitations in the event of emergencies—when a power failure or control system malfunction occurs, the drive mechanism will stop due to the loss of power, and the chain gate cannot descend conveniently using conventional automated methods. In this situation, not only will the cage be forced to stop operation because the gate cannot close, interrupting the continuous operation of the mine hoisting system and affecting the efficiency of underground material transportation and personnel descent; more seriously, if the gate is in a half-open state, it may cause safety hazards such as accidental falls and underground equipment falling through gaps, posing a direct threat to mine production safety and the lives of workers. Utility Model Content
[0005] The purpose of this invention is to provide an intelligent mine hoisting cage door, designed to solve the problem that when a power failure or control system malfunction occurs, the drive mechanism stops due to loss of power, and the cage door cannot be easily lowered using conventional automated methods. In this situation, not only will the cage be forced to stop operation because the door cannot close, interrupting the continuous operation of the mine hoisting system and affecting the efficiency of underground material transportation and personnel descent, but more seriously, if the door is in a half-open state, it may cause safety hazards such as accidental falls and underground equipment falling through gaps, posing a direct threat to mine production safety and the lives of workers.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mining intelligent cage chain door, including a cage door frame and a motor box installed at the top of the cage door frame. The output end of the drive motor inside the motor box is connected to a shaft. A winding roller is connected to the surface of the shaft. A steel wire rope is wound around the surface of the winding roller. A connecting block is connected to the bottom end of the steel wire rope. A connecting rope is connected to the bottom end of the connecting block. A stop bar is connected to the bottom end of the connecting rope.
[0007] The stop bar is connected to a bushing on its surface, and a chain link is connected to the top surface of the bushing. Both ends of the stop bar are connected to guide sleeves, and a guide rod is connected through the opening of the guide sleeve. An acoustic and optical sensor is connected to the inner wall of the cage door frame near the guide sleeve. A plug is connected to one end of the wire rope near the docking block. A locking screw is connected through one side surface of the docking block. A receiving block is connected to the other end of the locking screw. A wedge block is connected to the other side of the receiving block. A limit block is connected to the inner wall of the receiving block.
[0008] To facilitate the control of the tank chain door, as a preferred embodiment of this utility model of intelligent tank chain door for mining, a control line is connected to one side of the motor box, and a control handle is connected to the bottom end of the control line.
[0009] To ensure stable movement of the stop bar, as a preferred embodiment of this intelligent mine cage chain door, the guide rod is installed on the inner wall of the cage door frame, and the stop bar is slidably connected to the guide rod via a guide sleeve.
[0010] To facilitate folding, in the preferred embodiment of this utility model of a mining intelligent tank chain door, the bushing is connected to a bushing on the surface of another stop bar via a chain link.
[0011] To ensure accurate positioning of the lifting guide sleeve, preferably, the intelligent mine chain door of this utility model has two acoustic and optical sensors, which are level with the lowest end of the guide sleeve.
[0012] To facilitate locking and fixing the insert, in the preferred embodiment of this utility model of intelligent mine tank chain door, the locking screw is threadedly connected to the docking block, and a fixing groove is provided on the side of the insert near the wedge block. The wedge block and the fixing groove on the surface of the insert form an interlocking structure.
[0013] To facilitate stable movement of the insert block, the intelligent mine chain door of this utility model preferably has a limiting groove on the surface of the insert block near the limiting block, and the limiting groove on the surface of the insert block and the limiting block form a sliding connection structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention involves installing the cage door frame at the cage's inlet and outlet. By starting the motor inside the motor box, the winding roller on the shaft surface rotates, causing the wire rope to wind up. This causes the guide sleeves at both ends of the stop bar to move upwards along the guide rod. In the event of a power outage, the operator can reverse the rotation of the locking screw on the docking block surface. This causes the rotating block at one end of the locking screw to rotate along the opening on one side of the receiving block, and the wedge block to be removed from the fixing groove on the insert block surface. This loosens the insert block from the top opening of the docking block, facilitating the quick separation of the wire rope and connecting rope. This allows for the rapid lowering of the stop bar, ensuring safety during use. Attached Figure Description

[0025] Please see Figure 1-6 The present invention provides the following technical solution: a mine intelligent cage chain door, including a cage door frame 1 and a motor box 2 installed at the top of the cage door frame 1. The output end of the drive motor inside the motor box 2 is connected to a shaft 3. A winding roller 4 is connected to the surface of the shaft 3. A steel wire rope 5 is wound on the surface of the winding roller 4. A connecting block 8 is connected to the bottom end of the steel wire rope 5. A connecting rope 9 is connected to the bottom end of the connecting block 8. A baffle 10 is connected to the bottom end of the connecting rope 9.
[0026] A bushing 11 is connected to the surface of the baffle 10, and a chain link 12 is connected to the top surface of the bushing 11. Guide sleeves 13 are connected to both ends of the baffle 10. A guide rod 14 is connected through the opening of the guide sleeve 13. An acoustic and optical sensor 15 is connected to the inner wall of the cage door frame 1 near the guide sleeve 13. A plug block 16 is connected to one end of the wire rope 5 near the docking block 8. A locking screw 17 is connected through one side surface of the docking block 8. A receiving block 18 is connected to the other end of the locking screw 17. A wedge block 19 is connected to the other side of the receiving block 18. A limit block 22 is connected to the inner wall of the receiving block 18.
[0027] Preferably, a control line 6 is connected to one side of the motor housing 2, and a control handle 7 is connected to the bottom end of the control line 6. In actual use, the control handle 7 is used to conveniently control the folding operation of the can chain door;
[0028] Preferably, the guide rod 14 is installed on the inner wall of the cage door frame 1, and the baffle 10 is slidably connected to the guide rod 14 via the guide sleeve 13. In actual use, by sliding the guide sleeve 13 along the guide rod 14, it is convenient to move the bottom baffle 10 up and down.
[0029] Preferably, the bushing 11 is connected to another bushing 11 on the surface of the baffle 10 via a chain link 12. In actual use, the bushing 11 is connected to another bushing 11 via the chain link 12 on its surface, which facilitates the folding of the chain door.
[0030] Preferably, two acoustic and optical sensors 15 are provided, and the two acoustic and optical sensors 15 are flush with the guide sleeve 13 at the lowest end. In actual use, the acoustic and optical sensors 15 are connected to the device. At this time, the acoustic and optical sensors 15 identify the position of the baffle 10 at the lowest end. When the baffle 10 is not in the correct position, an alarm is issued, thus improving the intelligent effect.
[0031] Preferably, the locking screw 17 is threadedly connected to the mating block 8, and the insert block 16 has a fixing groove 21 on the side near the wedge block 19. The wedge block 19 and the fixing groove 21 on the surface of the insert block 16 form a fitting structure. In actual use, by rotating the locking screw 17, the wedge block 19 is easily driven to fit into the fixing groove 21 on the surface of the insert block 16, thus ensuring a stable fitting and connection between the wire rope 5 and the connecting rope 9.
[0032] Preferably, a limiting groove is formed on the surface of the insert block 16 near the limiting block 22, and the limiting groove on the surface of the insert block 16 and the limiting block 22 form a sliding connection structure. In actual use, by sliding the limiting groove on the surface of the insert block 16 along the limiting block 22, it is convenient to quickly separate the connecting rope 9 and the wire rope 5.
[0033] The working principle of this utility model is as follows: First, the cage door frame 1 is installed at the inlet and outlet of the cage. By operating the control handle 7, the motor inside the motor box 2 is started, which drives the winding roller 4 on the surface of the shaft 3 to rotate, causing the wire rope 5 to be wound up. At this time, the guide sleeves 13 at both ends of the baffle 10 move upward along the guide rod 14. If a power failure occurs, the operator rotates the locking screw 17 on the surface of the docking block 8 in the opposite direction. This causes the rotating block 20 at one end of the locking screw 17 to rotate along the opening on one side of the receiving block 18, and causes the wedge block 19 to be removed from the fixing groove 21 on the surface of the insert block 16. This makes the insert block 16 loose from the top opening of the docking block 8, and the limiting groove on the surface of the insert block 16 slides along the limiting block 22 on the inner wall of the docking block 8, which facilitates the quick separation of the wire rope 5 and the connecting rope 9. This allows the baffle 10 to be lowered quickly, ensuring the safety of use.
