Problems solved by technology
[0003] However, underground accidents are often caused by explosions, collapses, etc. If ordinary pipelines are subjected to the impact and vibration of airflow, and the tunnel collapse displacement squeezes and shears the pipeline, it will cause serious damage to the pipeline and cannot realize the life-saving function.

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Such as Figure 1 to Figure 9 As shown, a pre-installed retractable mine lifesaving pipeline, which includes two parts, a pipeline and a line. The pipeline includes a number of telescopic pipes 1 connected to each other through flanges, which can be stretched at corners or at the intersection of shafts and roadways. The tubes are connected by an elbow connector 2 or a multi-way connector 3; the telescopic tube 1 is composed of a thin tube 4 and a thick tube 5 fitted at both ends, and the two ends of the thin tube 4 fix the piston ring 7, the piston ring 7 is provided with two annular grooves 7, and a sealing rubber ring 8 is installed in each annular groove 7; the inner end of the thick tube 5 is fixedly sleeved on the thin tube 4 to block the end cover 9 of the piston ring 6, and the outer side of the thick tube 5 end fixing flange 10; the circ...

The invention discloses a prearranged retractable mine lifesaving pipeline. The prearranged retractable mine lifesaving pipeline comprises a pipe and a line. The pipe comprises a plurality of retractable pipes which are mutually connected through flanges, and the retractable pipes are connected through elbow connecting pieces or multi-way connecting pieces at positions of turnings or junctions between a shaft and roadways; the line is formed by a plurality of sections of cables packaged in the pipe in a connecting manner, and the length of the line is larger than the maximum extension length of the pipe; each section of cable comprises two power lines and eight data lines which are packaged in an outer sheath. The prearranged retractable mine lifesaving pipeline has the advantages that the structure is simple, the pipeline is convenient to use, the explosion-proof performance is high, the communication can be enabled to be smooth when underground accidents occur, the timely, accurate and effective rescue is facilitated, and the safety of underground miners is further guaranteed.
Description
technical field [0001] The invention belongs to the technical field of mine equipment, in particular to a preset retractable mine lifesaving pipeline. Background technique [0002] In the mining industry, underground accidents occur from time to time. The underground workers lose contact with the ground, cannot determine the location of the underground workers, and cannot provide timely ventilation, oxygen, drinking water and food, resulting in casualties. In order to reduce casualties in mine underground accidents, life-saving pipelines leading to the ground can be preset in each underground tunnel. In the event of an accident, the life-saving pipelines will collect underground information and introduce oxygen, water, liquid food, power, etc. from the ground into the underground. [0003] However, underground accidents are often caused by explosions, collapses, etc. If ordinary pipelines are subjected to the impact and vibration of the airflow, and the tunnel collapse displ...
