Abstract
The utility model discloses a kind of Mine Communication line protective devices; it includes the one section mine compressed air pipe parallel with communication cable; upper hole is processed on the two ends tube wall of mine compressed air pipeline respectively; the small anti-explosion wiring horn mouth of the upper feeding switch of welding on the plectane that welding one carries threading circular hole on each hole, plectane；One end explosion-proof wiring is incoming line, and other end explosion-proof wiring is line outlet；Parallel communication cable is pierced into from inlet wire mouth sealing ring, then drawn from other end outlet port sealing circle, is tightened through rear incoming line and line outlet with spiral and adds sealant sealing again；Communication cable after extraction is connected on outgoing line unit by separated time number, is connected by outgoing line unit with each communication apparatus or telephone set.Because communication cable is passed through out of air line, air line act as the part of protection pipe, improve the security that Mine Communication cable is used, it is ensured that the communication under mine emergency condition is unimpeded.
Description
Technical field
The utility model is related to the protection technique of Mine Communication circuit.
Background technology
In coal mining, downhole communication is very important, except the normal production of commander, it is often more important that for mine
Safety in production, so all the time will be in communicating unimpeded state.Extension and coal mine excavation depth with the pit mining time limit
Deepen top plate and lane side inbreak, rise side, machinery and personnel are not intended to destruction to communication line in addition, make during communication line causes
It is disconnected, influence the safety in production of mine.Because roadway structure tends to be complicated, trouble point is not easy to find, and maintenance is made to communication line
It is more and more difficult.In coal mining, generally use to press wind as the pneumatic equipment and instrument of power source, the pressure fan on well is adopted
Each getting working face of underground is led directly to air line, the energy is provided for pneumatic equipment.Being adopted mine compressed air pipe joint more
Connected with snap joint.Therefore, air line has no him in addition to delivery pressure wind and used.
The content of the invention
In order to realize the protection of communication line using the existing air line of mine, the utility model provides a kind of mine and led to
Interrogate line protective devices.
To reach above-mentioned purpose, the utility model is adopted the technical scheme that：
A kind of Mine Communication line protective devices, it is characterised in that it includes the one section mine pressure parallel with communication cable
Welding one on upper hole, each hole is processed on airduct, the two ends tube wall of mine compressed air pipeline respectively and carries threading circular hole
The small anti-explosion wiring horn mouth of upper feeding switch is welded on plectane, plectane；One end explosion-proof wiring is incoming line, and the other end is prevented
Quick-fried wiring is line outlet；Parallel communication cable is pierced into from inlet wire mouth sealing ring, then from other end outlet port sealing circle
Draw, tightened through rear incoming line and line outlet with spiral and add sealant sealing again；Communication cable after extraction presses separated time
Number it is connected on outgoing line unit, is connected by outgoing line unit with each communication apparatus or telephone set.
The utility model has the advantages that：Because communication cable is passed through out of air line, air line act as protection pipe
Part, improve the security that Mine Communication cable is used, it is ensured that the communication under mine emergency condition is unimpeded.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
In figure, 1- mine compressed air pipes, 2- holes, 3- plectanes, 4- incoming lines, 5- communication cables, 6- outgoing line units, 7- phones
Machine, 8- line outlets.
Embodiment
As shown in figure 1, a kind of Mine Communication line protective devices, it is parallel with communication cable 5 that it includes certain length
Processed respectively on that section of mine compressed air pipe 1, the two ends tube wall of mine compressed air pipe 1 on upper hole 2, each hole 2 and weld a band
There are the small anti-explosion wiring horn mouth that upper feeding switch is welded on the plectane 3 of threading circular hole, plectane 3, one end explosion-proof wiring loudspeaker
Mouth is incoming line 4, and other end explosion-proof wiring horn mouth is line outlet 8；By parallel communication cable 5 from the sealing ring of incoming line 4
In pierce into, then from the sealing ring of line outlet 8 draw, tightened with spiral through rear incoming line 4 and line outlet 8 and add fluid sealant again
Sealing；Communication cable 5 after extraction is connected on outgoing line unit 6 by separated time number, by outgoing line unit 6 and each communication apparatus or
Telephone set 7 is connected.
