Description

Technical Field

[0001] This utility model relates to the technical field of coal mine ventilation and rescue channels, specifically a coal mine ventilation and rescue emergency channel. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. Regardless of the type of coal mine, coal miners are needed to dig and extract coal. When a coal mine accident occurs, coal miners may not react in time and could easily be buried deep in the mine tunnel.

[0003] When workers are trapped inside a mine tunnel, it is difficult for them to rescue themselves. Calling for rescuers from above takes a long time, which reduces the workers' chances of survival. Furthermore, rescue operations require drilling to open up the tunnel, and the vibrations during the drilling process can easily cause secondary collapses in the tunnel, further reducing the chances of survival for the trapped workers. Therefore, we propose an emergency ventilation and rescue channel for coal mines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an emergency ventilation and rescue passage for coal mines, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal mine ventilation and rescue emergency passage, comprising a rescue pipe, wherein multiple ladders are fixedly connected inside the rescue pipe, multiple escape openings are provided inside the rescue pipe, and two corresponding first rotating shafts are rotatably connected inside the rescue pipe via bearings. A protective mesh plate is fixedly connected to the outside of the two first rotating shafts and inside the rescue pipe, and multiple sets of second baffles are fixedly connected inside the rescue pipe. The second baffles have slots inside, and two corresponding locking blocks are fixedly connected to one side of the protective mesh plate, the locking blocks engaging with the inside of the slots.

[0006] Preferably, a winch is installed on the outside of the rescue pipe. The winch consists of a connecting frame, a take-up roller, and a servo motor. A traction rope is wound around the outside of the take-up roller, and one end of the traction rope is fixedly connected to the outside of the take-up roller. A through groove is opened inside the rescue pipe, and two corresponding guide wheels are rotatably connected inside both the rescue pipe and the through groove. One end of the traction rope passes through the two sets of guide wheels and extends into the inside of the rescue pipe, where a fall protection suit is fixedly connected. Through the cooperation of the winch, the traction rope, and the fall protection suit, the injured trapped person can be hoisted up, thereby facilitating rescue and increasing the survival rate of the trapped person.

[0007] Preferably, the rescue pipe has a first transmission groove inside, and a second rotating shaft is rotatably connected to the inside of the first transmission groove via a bearing. A worm gear is fixedly connected to the outside of the second rotating shaft and inside the first transmission groove. A third rotating shaft is rotatably connected to the inside of the first transmission groove via a bearing, and a worm is fixedly connected to the outside of the third rotating shaft and inside the first transmission groove. The worm meshes with the worm gear. One end of the second rotating shaft is fixedly connected to one of the first rotating shafts, and one end of the third rotating shaft extends to the outside of the rescue pipe and is fixedly connected to a knob. Through the cooperation of the second rotating shaft, the worm gear, the third rotating shaft, the worm, and the knob, the protective netting can be rotated to allow trapped personnel to enter the interior of the rescue pipe, thereby facilitating escape via ladder climbing or hoisting of injured personnel via winch, traction rope, and fall protection clothing.

[0008] Preferably, the rescue pipe has a second transmission groove inside. A fourth rotating shaft is rotatably connected to the inside of the second transmission groove via a bearing.

One end of the fourth rotating shaft is fixedly connected to a third rotating shaft. A knob is fixedly connected to one end of the fifth rotating shaft. Through the interaction of the fourth rotating shaft, the first bevel gear, the fifth rotating shaft, and the second bevel gear, the second rotating shaft, the worm gear, the third rotating shaft, and the worm can be driven to rotate, thereby rotating the protective mesh panel and lowering it. This facilitates escape for trapped personnel through the escape opening or allows those who are physically exhausted to rest.

[0009] Preferably, a first baffle is fixedly connected inside the rescue pipe and on one side of the second baffle, and the first baffle cooperates with the protective mesh plate.

[0010] Preferably, a mounting frame is fixedly installed inside the rescue pipeline by bolts, a dust filter is installed inside the mounting frame, and a fan is fixedly installed inside the mounting frame.

[0012] This utility model provides an emergency ventilation and rescue passage in a coal mine, which has the following beneficial effects:

[0013] 1. This coal mine ventilation and rescue emergency passage features a ladder for trapped personnel to climb to the top of the rescue pipeline. The winch, traction rope, fall protection suit, and guide wheels work together to facilitate the rescue of injured personnel. Rotating the third rotating shaft drives the worm gear, which in turn drives the second rotating shaft and worm wheel, thus rotating the protective mesh panel. Alternatively, rotating the fifth rotating shaft and the second bevel gear drives the first bevel gear and the fourth rotating shaft, which in turn drives the third rotating shaft, worm gear, second rotating shaft, and worm wheel to lower the protective mesh panel. This allows trapped personnel outside the rescue pipeline to escape through the escape hatch, or those climbing up from below to escape through the escape hatch. It also allows personnel who are exhausted during the climb to rest, improving the practicality of the coal mine ventilation and rescue emergency passage.

[0014] 2. The ventilation and rescue emergency passage in this coal mine, through the cooperation of the mounting frame, fan and dust filter, can ensure the ventilation effect inside the rescue pipeline, thereby ensuring air circulation inside the rescue pipeline and increasing the survival rate of trapped personnel. The top cover prevents rainwater from falling into the rescue pipeline, thus improving the practicality of the ventilation and rescue emergency passage in the coal mine. Attached Figure Description
