Background technology
Gas is outstanding to be the key subjects in more than 100 year of puzzlement world's coal mining, especially in recent years along with the increase of the depth of excavation, owing to there is not special-purpose protrusion-dispelling sniffer, position to gas outstanding (gas capsule) can not accurately be found out and eliminate, cause gas burst accident frequently to take place, caused very large loss for people's life and property.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned prior art, provides a kind of simple to operate, easy to use, shows the protrusion-dispelling sniffer of gas capsule size by force value.
Realize the foregoing invention purpose by the following technical solutions, a kind of protrusion-dispelling sniffer, its composition comprises hydraulic pump, support and oil cylinder, its lower carriage stands on the colliery tunnel, and described hydraulic pump and hydraulic oil container are mounted on the base with pipeline, and hydraulic oil container is connected with hydraulic jack by hydraulic oil pipe, this hydraulic jack laterally is placed on the lower carriage seat, one end is connected with the horizon adjustable support, and the other end is connected with feeler by cylinder rod, and pressure meter and hydraulic jack are mounted on the base.
Compared with prior art, the utility model is with pressure meter and hydraulic jack, feeler, the Hydraulic Station combination, provide power by Hydraulic Station for hydraulic jack, by feeler respectively to the tunnel rib with drilled the pressurization of hole root, whether find out projecting coal bed gas capsule by pressure differential composes and deposits wherein, press operation that foundation is provided for whether needing to bore to drain, fundamentally stop and avoid gas burst accident to feed the injury that the well personnel bring, simplify the protrusion-dispelling program and reduce the protrusion-dispelling cost, thereby ensure safety in production, this apparatus structure is simple, and the blank of mash gas outburst prevention field of detecting has been filled up in simple operation.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Among the figure, inspecting hole 1, feeler 2, cylinder rod 3, oil cylinder 4, carrier base 5, horizon adjustable support 6, hydraulic oil pipe 7, hydraulic oil container 8, distributing valve 9, control stick 10, pressure meter 11, hydraulic pump 12, shaft coupling 13, motor 14, base 15, lower carriage 16, tunnel rib 17.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
See accompanying drawing 1, present embodiment is a kind of protrusion-dispelling sniffer, is made up of Hydraulic Station, feeler and support.Hydraulic Station is made up of hydraulic oil container 8, motor 14, hydraulic pump 12, pressure meter 11, distributing valve 9 and control stick 10.Hydraulic pump 12 is connected with motor 14 by shaft coupling 13, is connected with hydraulic oil container 8 usefulness pipelines.Distributing valve 9, control stick 10 are installed on the hydraulic oil container 8.The Hydraulic Station of being made up of hydraulic oil container 8, motor 14, hydraulic pump 12, pressure meter 11, distributing valve 9 and control stick 10 is installed on the base 15.Hydraulic oil container 8 is connected with hydraulic jack 4 by hydraulic oil pipe 7, and pressure meter 11 is connected with hydraulic jack 4.
Support is made up of adjustable lower carriage 16 and horizon adjustable support 6, firm in order to support, utilize leg-of-mutton principle, lower carriage 16 adopts spiral adjustable A-frame, the top of A-frame is provided with carrier base 5, this carrier base 5 is hinged with A-frame, and lower carriage 16 is supported in the tunnel of colliery.
Operating principle
Produce thrust (thrust is exactly that its numerical values recited of pressure gauge pressure should be determined according to ature of coal) by hydraulic jack 4, the hole bottom application that promotes 3 pairs of tunnel ribs of feeler 17 and the hole of drilling 1 is with roof pressure (pressure gauge pressure), and give feeler 2 one horizontal supports by horizontal adjustable support 6, record the force value of the rib of visiting 17 and inspecting hole 1 bottom, if pressure meter 11 shows that inspecting hole 1 bottom is identical with tunnel rib 17 roof pressures (pressure meter need be provided with maximum value), just there is not the gas capsule herein in explanation, can not go out danger, the not row's of boring operation, have the gas capsule herein if instead the roof pressure (pressure gauge pressure) in the inspecting hole 1 is far smaller than the roof pressure (pressure gauge pressure) of tunnel rib 17 or do not have roof pressure (pressure gauge pressure) just to illustrate, take the row's of boring operation so that eliminate outburst danger, thereby ensure safety in production, this device has been filled up the blank of mash gas outburst prevention field of detecting.
Operating process
When carrying out gas capsule detection (protrusion-dispelling) operation, actuating motor 14 drives hydraulic pumps 12 work by shaft coupling 13, and hydraulic oil provides power through hydraulic oil pipe for hydraulic jack 4.
Adjust feeler 2 positions, aim at 1 A of tunnel rib 17, distributing valve 9 and the control stick 10 control hydraulic jacks 4 of adjusting hydraulic oil container 7 move and exert pressure, after recording maximum roof pressure (pressure gauge pressure) and record, exert pressure by 1 pair of gas capsule boring of inspecting hole B point with feeler 2 again, identical as the roof pressure (pressure gauge pressure) in the gas capsule boring hole with the roof pressure (pressure gauge pressure) of tunnel rib 17 set point A, then there is not the gas capsule to exist herein, if the roof pressure (pressure gauge pressure) that boring B is ordered is significantly less than A point roof pressure (pressure gauge pressure) or feeler 2 move speeds are very fast, resistance (pressure gauge pressure) is very little, just there is the gas capsule herein in explanation, to take the row's of boring measure as early as possible, avoid casualties and reduce the protrusion-dispelling cost to eliminate outstanding hidden danger, to ensure safety in production.
