Technical Field

[0001] The utility model relates to the technical field of mines, in particular to a safety protection device for an underground unloading station. Background Art

[0002] A mine refers to an independent production and operation unit that extracts ore with a certain mining boundary. Mines mainly include one or more mining workshops or adits, mine shafts, open-pit mines, etc. and some auxiliary workshops. The underground unloading station is an important link in the mine transportation system. Its main function is to load, unload and transfer materials such as ore or ore materials collected underground, and finally send them to the ground or other destinations. The underground unloading station is an important place in the process of transferring underground ore and waste rock. There are certain safety hazards underground. Existing unloading stations also have some safety facilities, such as signal systems, which can help drivers communicate with winch drivers and indicate operations such as up, down, slow up, slow down, etc., making the underground transportation process more standardized and safe. However, this method has the problems of relatively large dust during unloading, and the stone breaker must stand on the grizzly screen for operation, with a relatively high risk of being injured by misunloaded ore or waste rock or falling into the chute. Summary of the Invention

A second spray pipe 55 is connected above the second water pump 54. Spray nozzles 56 are installed on the outer sides of both the second spray pipe 55 and the first spray pipe 52. A closed cover plate 61 is installed above the second motorized mine car 31, and a hydraulic cylinder 6 is installed above the closed cover plate 61 through a turning shaft. The alarm 11 gives an audible and visual alarm to prompt workers to wear the safety belt 21. After wearing it, it can prevent workers from falling into the chute. The first motorized mine car 3 reaches the front of the feed grid 12 through the track, and the limit baffle 42 blocks the first motorized mine car 3. When the limit baffle 42 moves, the spring 41 cooperates with the hydraulic damper 4 to absorb the impact received by the limit baffle 42, thereby achieving the purpose of preventing accidental unloading of ore. By adopting the above method, the safety of the device can be effectively increased, and the risk of workers being injured by accidentally unloaded ore or waste rock or falling into the chute can be effectively avoided. The hydraulic cylinder 6 pulls the closed cover plate 61 to turn and open to block the dust. The first water pump 51 transports the liquid inside the first water storage tank 5 to the first spray pipe 52 and sprays it above the feed grid 12 through the spray nozzles 56. The second water pump 54 transports the liquid inside the second water storage tank 53 to the inside of the second spray pipe 55 and sprays it outside the second motorized mine car 31 through the spray nozzles 56. By adopting this method, the dust during ore unloading can be effectively reduced. The safety belt 21 includes a hanging ring and a safety buckle with a sensor. The hanging ring can facilitate the sliding of the safety belt 21 along the support steel beam 2. Through the safety buckle with a sensor, it is convenient for the terminal to detect whether the worker wears the safety belt 21. The first spray pipe 52 is arranged in a U shape, and the first spray pipe 52 and the feed grid 12 are arranged parallel to each other. The U-shaped first spray pipe 52 can achieve the purpose of dust reduction when the ore passes through the feed grid 12. The U-shaped setting can ensure the efficiency and effect of dust reduction. And the parallel arrangement of the first spray pipe 52 can ensure the dust reduction effect of the first spray pipe 52 on the unloading area. Two second water storage tanks 53 are symmetrically arranged about the center line of the second motorized mine car 31.The symmetrically arranged water storage tank two 53 can cooperate with the water pump two 54 and the spray pipeline two 55 to comprehensively and reliably reduce the dust of the motor mine car two 31. A chute is provided at the position of the mine body 1 close to the limit baffle 42, and a clamping and sliding installation structure is formed between the limit baffle 42 and the mine body 1 through the chute, which is convenient for absorbing the impact of the motor mine car one 3.

The spring 41 and the hydraulic damper 4 can comprehensively and reliably absorb the impact of the limit baffle 42, and the sliding of the limit baffle 42 can be guided and limited through the chute. Two hydraulic dampers 4 are symmetrically arranged about the midline of the motor mine car one 3. The two symmetrically arranged hydraulic dampers 4 can cooperate with the spring 41 and the limit baffle 42 to absorb the impact of the motor mine car one 3, achieving the purpose of preventing accidental unloading of ore. The hydraulic cylinder 6 is connected to the mine body 1 through a turning shaft. The closing cover plate 61 is connected to the mine body 1 through a turning shaft, and a rotating installation structure is formed between the closing cover plate 61 and the mine body 1 through the hydraulic cylinder 6. The hydraulic cylinder 6 pulls the closing cover plate 61 to flip and open. When the hydraulic cylinder 6 pulls the closing cover plate 61, the hydraulic cylinder 6 will rotate along the turning shaft, and the closing cover plate 61 will also rotate along the turning shaft. The turning shaft can guide and limit the flipping of the closing cover plate 61. Using this method can make the opening of the closing cover plate 61 more convenient and fast.

[0034] The working principle of the present utility model is as follows: When using this device, workers enter the interior of the mine body 1. At this time, the alarm 11 gives an audible and visual alarm to prompt the workers to wear the safety belt 21. After wearing it, it can prevent the workers from falling into the ore pass. The motor mine car one 3 arrives in front of the feeding grid 12 through the track. The limit baffle 42 blocks the motor mine car one 3. When the limit baffle 42 moves, the spring 41 and the hydraulic damper 4 absorb the impact received by the limit baffle 42, thereby achieving the purpose of preventing accidental unloading of ore. Before unloading the ore, the hydraulic cylinder 6 pulls the closing cover plate 61 to flip and open to block the dust. When unloading the ore, the water pump one 51 transports the liquid in the water storage tank one 5 to the spray pipeline one 52 and sprays it above the feeding grid 12 through the spray nozzle 56. Using this method can provide dust protection during unloading. The ore enters the interior of the motor mine car two 31 through the feeding grid 12. At this time, the water pump two 54 transports the liquid in the water storage tank two 53 into the spray pipeline two 55 and sprays it on the outside of the motor mine car two 31 through the spray nozzle 56, and the device is dust-reduced again. Using this method can effectively reduce the dust during ore unloading.
