Abstract

The invention discloses a coal mine emergency rescue and escape device. The device comprises a containing base, a fixing block, a first connecting rod and a second connecting rod; a sliding slot is formed in the outer surface of the left side of the containing base, and a protective cover is arranged on the outer side of the sliding slot; movable rods are rotatably connected to the inner surface of the protective cover and connected to the outer surface of the containing base, connecting blocks are arranged on the outer surfaces of the movable rods, a second spring is arranged on the outer surface of a first rotating block, and a second rotating block is arranged on the right side of the second spring; a sliding block is rotatably connected to the inner surface of the upper end of the containing base and connected with a protrusive block. The coal mine emergency rescue and escape device is provided with a movable door capable of being opened and closed conveniently; meanwhile, when outer crushed stone and the like hit the surface of the movable door after the movable door is closed, a limiting block on the inner surface of the containing base can stably abut against the movable door from the inner side to prevent the movable door from being forced open by an external force, and the safety of the device is ensured.

Description

technical field [0001] The invention relates to the technical field of coal mine emergency, in particular to a coal mine emergency rescue and escape device and a use method. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. my country has always been a large country with coal mines, and the number of coal mines is also large, resulting in frequent large-scale mine disasters, and accidents are sudden and unpredictable. Thereby constituted a serious threat to the personal safety of the underground roadway staff, so most coal mines have been provided with emergency rescue and escape passages, and there are certain defects in the existing coal mine emergency rescue and escape devices, such as: [0003] 1. The existing emergency passage is inconvenient for users to escape quickly, and the escape door is inconvenient for users to open and close quickly. After closing, it cannot effectively resist the dumping pres...
