The embodiment of the present application is solved by providing a kind of full automatic gas pressure hole cleaning device drilled for deep rock mass engineering project Rock debris in engineering the drilling in the prior art, dust etc. can not be efficient, the technical problem of convenient removing;Reach that lifting is removed The technique effect of effect and operating reliability.
In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper State technical scheme to be described in detail, it should be understood that the specific features in the utility model embodiment and embodiment are to this Shen Please technical scheme detailed description, rather than the restriction to technical scheme, in the case where not conflicting, the application is real Applying the technical characteristic in example and embodiment can be mutually combined.
Referring to Fig. 1, a kind of full automatic gas pressure hole cleaning device drilled for deep rock mass engineering project, including:Inflatable airbag 1st, pulling force sensor 3, pull bar 2, charge and discharge air pipe 5, air pump 8 and controller 6.
Specifically, the inflatable airbag 1 is connected by the charge and discharge air pipe 5 with the air pump 8;That is, foundation is filled The inflation/deflation operation structure of gas formula air bag 1, is adjusted with the swelling state for specifically performing inflatable airbag 1, for tackling borehole cleaning mistake The change in aperture in journey.
The inflatable airbag 1 is connected by the pulling force sensor 3 with the pull bar 2;Applying for pull bar 2 is measured in real time Power, feeds back to controller 6, for reflecting status of the air bag in hole.And in this, as a Con trolling index, feedback control The inflation/deflation of air bag, can keep stable pressure, so as to ensure the reliability of elimination effect and clear operation with hole wall.
Specifically, the pulling force sensor 3 is connected with the control 6, obtains pull bar 2 and is applied to the inflatable airbag 1 pulling force;The charge and discharge air pipe is connected with the controller, controls inflation/deflation process.
Wherein, during borehole cleaning, inflatable airbag 1 is placed in engineering the drilling 18, under the control of the controller 6, The air pump 8 is inflated by the charge and discharge air pipe 5, until the inflatable airbag 1 is expanded against the engineering the drilling 18 Hole wall;Then, operate the pull bar 2 to draw the inflatable airbag 1 of swelling state to outside hole, the rubble in hole is promoted to outside hole Consider dust to be worth doing.
It is necessary explanation, the pulling force sensor 3 monitors the force of pull bar 2 and returns to the controller 6 in real time, During borehole cleaning, when pull bar 2 is paused suddenly by external force, the stress of pull bar 2 suddenly rises, and pulling force monitor value is more than the first preset value When, the controller 6 controls the charge and discharge air pipe 5 to release the gas in the inflatable airbag 1, until the pulling force is dropped to Below first preset value, in this process, operator still applies certain pulling force to pull bar 2, is stranded until inflatable airbag 1 passes through Difficult region;I.e. in the case where keeping elimination effect, it is ensured that borehole cleaning process is smoothly completed.
Generally directed to be the situation that the aperture that error causes reduces of drilling, or deep engineering is bored under condition of high ground stress Hole locally occur cake, it is uneven situations such as.
When monitor value is less than the second preset value, the controller 6 controls the charge and discharge air pipe 5 to the inflatable gas Capsule 1 is inflated, more than the pulling force to the second preset value.The stabilization of inflatable airbag 1 and the contact of hole wall is realized, from And increase frictional force, on the premise of ensureing that borehole cleaning process is smoothly completed, it is ensured that elimination effect.
Generally directed to be that aperture becomes big situation, specifically can also be there is local dent, or pass through the aperture , it is necessary to recover the situation of the air bag bulbs of pressure after the regional area of diminution.
The air pump is pressure constant air pump;
When the monitor value is 0, the controller control the charge and discharge air pipe keep the pressure constant air pump with it is described Inflatable airbag connected state;
Wherein, the output pressure of the constant pressure air bag is less than first preset value and more than second preset value.
That is, if when suspending, pulling force sensor is substantially that can't detect pressure in cleanup process, i.e., monitor value is 0, Now by keeping the unimpeded of loading line, the air pressure of air bag is able to maintain that, is unlikely to release or air pressure is excessive, keeps preferable Borehole cleaning state, this is the natural gaseous state change shared based on air pressure, efficiently and rapid.
Voltage-controlled system is output it between the first preset value and the second preset value, preferable swelling state can be kept, had Help maintain the efficiency of borehole cleaning.
