Description
Technical field
The present invention relates to a kind of underground safety check technologies, specifically provide a kind of utilization pressure sensor safety detection technology side
Case.
Background technique
Now, mining hydraulic support apparatus is that mine working face ensures safe important equipment, due to underground geologic structure
Complexity, the natural trend of mine pressure pressure and the leakage phenomenon of hydraulic medium cause hydraulic prop equipment working resistance unbalanced existing
As being that top plate is caused to loosen the main contributor that the accidents such as column and superpressure landslide occur.But now widely used hydraulic branch
Shield product itself does not have safety detecting alarm function to working resistance, often because working resistance is too small or excessive causes down column
The phenomenon that top plate collapses or because overload causes the continuous generation of the accidents such as disconnected column landslide, the decompression or superpressure of hydraulic prop equipment
, this will cause branch major gene and loses support force and collapse, or because of multiple monomers or support force uneven distribution, so that
Top beam slump, easily causes human casualty accident and property loss.Present underground security staff is the generation for preventing accident, is adopted
The method taken is frequently to carry out tours of inspection to the support force of hydraulic device, by shaking or beaing the equal means pair fallen behind very much
The working resistance of pillar is checked one by one, not only timely and effectively cannot be found and be solved the problems, such as, while also waste is a large amount of
Whether normal time and efforts can not timely understand the current working condition of hydraulic prop equipment at all, therefore at all can not
Exclude potential security risk.The hydraulic pressure of hydraulic prop for mine is bigger, and piston stress is also bigger, and big stress needs
It is measured with the use of big spring, existing piston uses unified uniform cylindrical shape in addition, because of hydraulic pressure
It obtains using the piston of path greatly and is matched using big spring, required big stress spring occupancy volume is larger, inspection
Measurement equipment is at high cost, transports inconvenient to use.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technical problems, have provided a kind of utilization pressure sensor peace
Full inspection survey technology scheme.
Pressure sensor safety detection technology scheme is utilized the present invention provides a kind of, it is characterised in that: including tubular valve
Set, valve pocket is interior to be equipped with screw rod, piston and compressed spring, and piston is equipped with the boss higher than piston only, and boss one end is arranged with
Compressed spring, compressed spring are arranged screw rod, and the screw rod other end is against on pressure sensor, and the pressure sensor other end is against induction
On the contact-making switch of indicator light, the installation of induction indicator light passes through the stifled one end for being mounted on valve pocket of electro-insulating rubber, the other end of piston
Sliding is cased with axle sleeve, and the first sealing ring is equipped between piston and axle sleeve, and the second sealing ring is equipped between axle sleeve and valve pocket.
Advantages of the present invention:
Of the present invention to utilize pressure sensor safety detection technology scheme, detection device has structure simple, compact, installation
The advantages of it is time saving and energy saving to dismantle, easy to process, and sealing effect is good, and measurement is accurate, and service life is extended.
