Abstract
The invention discloses an automatic protection wall elastic net releasing device capable of preventing drilled hole collapse. The automatic protection wall elastic net releasing device comprises two parts, namely, a protection body plate and a rod body for opening the protection body plate. The protection body plate is formed by an elastic plastic sheet with mesh-shaped seams. Lug bodies with circular holes are arranged on the left side of the protection body plate. The protection body plate can be opened and closed through the rod body. The rod body is composed of a main rod and multiple pin bodies. The rod body can be separated from the protection body plate in the specific state so that the protection body plate can be opened under the effect of the elasticity of the protection body plate and can be tightly attached to hole walls to support drilled holes. Lug bodies on the right side of the protection body plate are long cylindrical holes with openings, and the rod body can be inserted in the long cylindrical holes and can longitudinally and freely move. In the state that the protection body plate is opened, the protection body plate and the rod body are connected, and the normal drill stem work cannot be influenced by the rod body. The hole collapse generated in the drill-in process and generated after hole forming during underground drilling is effectively prevented.
Description
Technical field
The present invention relates to preventing the guard technology of drill hole caves under mine, belong to drilling technology field used for geological prospecting and coal
Ore deposit security fields, are specially suitable for difference coal（Rock）The preventer preventing drill hole caves during long drilled holes is made in layer.
Background technology
Coal bed gas extraction boring, water injecting drilling in drilling process, due to the own physical mechanical property of coal（Soft）,
The factors such as the vibrations of drilling rod lead to collapse hole of holing, and still can take place frequently after pore-forming collapse hole sometimes, have a strong impact on boring progress, tight
Ghost image rings gas pumping efficiency or water-injection efficiency.
For the problems referred to above, the anti-collapse hole measure adopting at present mainly improves drill bit, the method is more single, effect not
Substantially, due to not protecting to hole wall, caving in of the wall of a borehole therefore can not effectively be prevented.
Content of the invention
It is an object of the invention to provide a kind of preventer preventing drill hole caves, solve down-hole drilling under existing well and boring
Enter with pore-forming after occur drill hole caves, cause bit freezing with blocking drilling problems, impact boring drilling and use, bring construction
Waste on middle time and cost.
The present invention adopts the following technical scheme that realization：
A kind of retaining wall elastic network(s) automatic releasing device of prevention boring collapse hole, including protection main board, on described protection main board
Offer the perforate being covered with plate body, described protection main board upper end arranges row's timber wedge shape projection, its lower end arranges a row and wood
The corresponding perforate of wedge-like projection ；The described protection main board side setting ear body with circular hole for the string, described protection main board one
Side is vertically arranged with the ear body with elongated hole, described elongated hole is provided with longitudinal gap；Described long in the hole penetrates the body of rod, the described body of rod
On be provided with pin rod corresponding with circular hole.
During installation, protection main board can be with flexural deformation, when protection main body plate closing is circle in the presence of artificial hand-power
Retaining wall elastic network(s) automatic releasing device is constituted, the pin rod of the body of rod inserts corresponding ear body during columnIn circular hole；Will be arranged on anti-
Shield another body of picking up the ears of main boardOn the body of rod shank insertion one circular hole of picking up the ears body I, be allowed to close.When two adjacent shields
When wall elastic network(s) automatic releasing device connects, next retaining wall elastic network(s) automatic releasing device is located at the timber wedge shape projection of its upper end
Just insert the corresponding aperture that a retaining wall elastic network(s) automatic releasing device is located at its lower end Interior.Preventing drill hole caves
After preventer enters boring, by preventing the control method of the preventer of drill hole caves, protection main board is made to open, to brill
Support action is played in hole, solve the problems, such as down-hole drilling in drilling process with pore-forming after collapse hole.
Application prevents the control method of the preventer of drill hole caves, using following steps：
A, when just drilling, the preventer preventing drill hole caves is not installed.
B, boring get to need stacks when, install on drilling rod prevents the preventer of drill hole caves simultaneously, prevents
The protection main board of the preventer of drill hole caves can be with flexural deformation, by opening protection function main board in the presence of artificial hand-power
The body of rod shank insertion left side ear body circular hole, be allowed to close.
C, prevent the preventer of drill hole caves to be enclosed within drilling rod, firmly one push away toward in boring, preventing drill hole caves
When bottom hole shifted onto by preventer, because the termination of the body of rod of opening protection function main board is longer one section than protection main board, open simultaneously
The shank of the body of rod of protection main board is the circular hole of insertion left side ear body, and the body of rod of opening protection function main board can be made to draw back,
The shank of the body of rod of opening protection function main board is made to exit circular hole, protection main board is opened in the presence of elastic force, deep with boring
Degree continuous propulsion, after repeatable operation.
D, the continuous propulsion with drilling depth, the follow-up preventer preventing drill hole caves when mounted, needs logical
Cross 4 perforates corresponding with it of the timber wedge shape on protection main board to be connected, can extract out on drilling rod after perforating finishes
Wrap up the unspent preventer preventing drill hole caves.
The present invention passes through the movement to protection main board for the control bar body phase, realizes to coal（Rock）The protection of layer boring.Economical
Cost is relatively low, and installation process is convenient and reliable, has the advantages that structure is simple, easy to process and low cost.
