Abstract
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
The invention belongs to equipment technology field, mine, the scalable mine life saving pipeline of especially a kind of presetting system.
Background technology
In mining industry, down-hole accident happens occasionally, underground labour and ground out of touch, the position residing for underground labour cannot be determined, oxygen supply of can not ventilating in time, provide drinking-water and food and cause casualties.In order to reduce mine down-hole accident casualties, can in down-hole, each tunnel be preset leads to the lifesaving pipeline on ground, once have an accident, by information under lifesaving pipeline production wells, and by oxygen, water, liquid food, power supply etc. from introducing down-hole, ground.
But down-hole accident is all often caused by situations such as exploding, cave in, adopt that common pipeline is subject to the shock and vibration of air-flow, tunnel caves in displacement extrusion shearing pipeline, pipe-line can be caused seriously to damage, can not life-saving functions be realized.
Summary of the invention
The object of the present invention is to provide the scalable mine life saving pipeline of a kind of presetting system, its structure is simple, easy to use, anti-knock properties are strong, and when can ensure that down-hole has an accident, communication is unimpeded, be beneficial to timely, accurate and effective suing and labouring, make the how a safety assurance of down-hole absence from work without reason.
The technical solution adopted in the present invention is achieved in that the scalable mine life saving pipeline of a kind of presetting system, it comprises pipeline and circuit two parts, it is characterized in that: described pipeline comprises some by the interconnective telescopic tube of flange, corner or vertical shaft with between tunnel intersection telescopic tube by bend connecting fitting or lead to fitting more and be connected; The extra heavy pipe that telescopic tube is set with by a tubule and two ends is formed, the two ends fixed piston ring of tubule, and piston ring is provided with 1 ~ 4 cannelure, in each cannelure, install O-ring seal; The medial extremity fixed cover of extra heavy pipe stops the end cap of piston ring on tubule, the outboard end mounting flange of extra heavy pipe; Described circuit is formed by connecting by the cable that some sections are encapsulated in pipeline, and the length of circuit is greater than pipeline maximum extension length; Every section of cable all comprises and is encapsulated in two power lines in oversheath and eight data lines; Plug is installed in one end of cable, the other end of cable installs the socket corresponding with plug, rotatable lock nut fixed by the plug or socket of cable one end, socket corresponding to the cable other end or plug have the external screw thread corresponding with lock nut internal thread.
Further, vertical shaft pipelines is set with one at interval of 1 ~ 3 telescopic tube below flange and lifts ring, two drag ropes be connected respectively to lift ring both sides earrings on pipeline flexible is lifted in vertical shaft.
The invention has the advantages that:
1, form telescopic tube, the bend connecting fitting of pipeline and lead to fitting more plastic material can be used to make; Plastic material has scalable, flexible feature in certain amplitude; especially the telescopic tube forming pipe main body has significantly scalability; mine blast the accident such as to cave in time; pipeline can be out of shape in stretch bending; but it can ensure the sealing performance that pipeline connects all the time, in pipeline, the length of circuit is greater than pipeline maximum extension length, and circuit has enough spread lengths; under the protection of conduit enclosure, also can not there is phenomenon of rupture in circuit.
2, tubule and its two ends piston ring, extra heavy pipe and end cap, fixing between extra heavy pipe and flange can adopt hot-melt adhesive paste, make easily, with low cost, can in various mines wide popularization and application.
3, pipeline is formed by connecting by some telescopic tubes, circuit is formed by connecting by some cables be encapsulated in pipeline, and in down-hole along with the propelling of work plane, pipeline and circuit can follow lengthening at any time, underworkings does not deposit dead angle, greatly enhances mine accident security performance.
Although 4, pipeline is formed by connecting by some telescopic tubes, can be provided with on sealing mat, piston ring at flange connections and be provided with O-ring seal, whole seal for pipe joints is functional, in pipeline except circuit, also has very large ventilation space, after generation accident of mine disaster, can realize writing to each other by circuit, can also by pipeline to delivered downhole air, water or liquid food.Wrecked personnel's time-to-live can be extended, race against time to rescue.
