Description
Technical field
The present invention relates to a kind of perforation major part slip casting constant-resistance anchor pole in support equipment.
Background technology
Bolting with wire mesh mode is widely used in mine, and combined support with bolt-net-cable mode substitutes existing shed shoring mode gradually, and Supporting Theory of Broken Rock Zone, that anchor net forms built-up arch force structure is ripe; But along with adopting dark to increase and after the anchoring of soft rock problem termination point of anchor rod, Bolted Rock Masses earlier breakage supporting failure phenomenon occurs often.Existing bolting with wire mesh rockbolt stress increases, and there will be Bolted Rock Masses broken invalid problem and rockbolt stress conical funnel structure and diminishes and reduce built-up arch strength problem.The existing bolting with wire mesh of application circumstances of the heavily stressed bolting with wire mesh of large mining depth, soft rock bolting with wire mesh and fractured coal and rock bolting with wire mesh is difficult to adapt to, develop a kind of anchor pole being suitable for the use of above-mentioned particular surroundings, this anchor pole should have the feature increasing anchored force, increase anchoring area, strengthen the distortion of built-up arch intensity, high-pressure slip-casting and constant-resistance; Constant-resistance can be out of shape pressure release, for mine safety production provides safeguard when being subject to bump simultaneously.
Summary of the invention
For the defect of existing anchor-net Shoring Technique, the object of this invention is to provide a kind of product of perforation major part slip casting constant-resistance anchor pole.
A kind of perforation major part slip casting constant-resistance mooring rod technique design features provided by the invention is: perforation major part slip casting constant-resistance anchor pole mainly comprises blasting and perforating device, O type sealing of hole powder stick device, high-pressure slip-casting device, constant-resistance deformation device, lengthens checkout gear and extend anchor cable device.
Preferably, described blasting and perforating device is the pellet perforation structure of the radial CUMULATIVE BLASTING of axial end iron, fixed bar, radial perforated casing, pellet, barb and the medicine that detonates composition; Radial CUMULATIVE BLASTING in yolk coal rock stratum or broken soft rock, makes the pellet on radial perforated casing have high speed kinetic energy, utilizes high speed pellet perforation to form the slip casting hole of anchor (rope) club head bump contact.
Preferably, described O type sealing of hole powder stick device is that upper O type stirs leather cup, lower O type stirs leather cup and the hollow O type sealing of hole powder stick structure of O type sealing of hole powder stick composition; To the O nibs afterbody shutoff having anchor (rope) bar obstruction in boring, so that shutoff boring afterbody before high-pressure slip-casting.
Preferably, described constant-resistance deformation device is the constant-resistance deformable solid piston structure of outer tube, O type resin distortion cover and wedge head pull bar composition; Outer tube and wedge head pull bar form piston structure, O type resin distortion cover plays solid dielectric effect therebetween, when constant-resistance deformation device is subject to specified pulling force, the O type resin distortion sleeve solid medium deformation constant-resistance pressure release of solid piston structure, ensures the stable constant-resistance pressure release continued under solid piston structure function of constant-resistance deformation device.
Preferably, described lengthening checkout gear be cushion cover, add long connecting rod, baffle plate and nut composition auxiliary detection instrument installing/dismounting add long support structure; Add long connecting rod and be connected to anchor pole afterbody, cushion cover, baffle plate and instrumentation are set in successively and add on long connecting rod, cushion cover and baffle plate support constant-resistance anchor rod pallet board, add long connecting rod tension constant-resistance anchor pole afterbody simultaneously nut be pressed on instrumentation, ensure that delayed constant-resistance rockbolt installation installed by instrumentation, avoid country rock disturbance and anchor pole in tunneling process to lose efficacy to detection data influence.
Preferably, described prolongation anchor cable device is the prolongation constant-resistance anchor structure of anchor cable of being threaded; Helicitic texture is set at anchor cable afterbody, is connected to form the constant-resistance anchor pole that anchor cable extends.
The product of perforation major part slip casting constant-resistance anchor pole of the present invention, solves the existing common bolt problem that supporting intensity is low under the complex geological condition of heavily stressed, soft rock and fragmented rock body.Existing common bolt, under above-mentioned geological conditions, there will be little anchoring area coal and rock broken invalid or the stressed conical funnel built-up arch intensity that diminishes and declines when the anchoring of anchor pole normal pressure, the little stressed increase of anchoring area; Impact force action anchor pole when anchor pole can not be out of shape causes supporting global failure, and the whole detection equipment safety that anchor pole afterbody is installed simultaneously reclaims difficulty.Develop a kind of anchor pole being suitable for the use of mine particular surroundings, this anchor pole should have the feature increasing anchored force, increase anchoring area, strengthen the distortion of built-up arch intensity, high-pressure slip-casting and constant-resistance; Constant-resistance can be out of shape pressure release when being subject to bump, the checkout gear that afterbody is installed is for lengthening the recyclable structure of safety simultaneously.Its advantage is as follows:
1, perforation major part slip casting constant-resistance anchor pole forms blasting and perforating crack or hole by blasting and perforating device at termination point of anchor rod (in fractured coal and rock), in termination fractured coal and rock (soft rock), major part anchoring rod is formed again by O type sealing of hole powder stick device shutoff boring afterbody and high-pressure slip-casting device, increase anchoring lifting surface area and form stressed anchoring major part body in weak stratum (soft rock) inside, make the conical funnel force structure of original small area of contact become the large-area halfpace force structure in large termination, increase built-up arch thickness and improve supporting bulk strength;
2, said apparatus can with common bolt with the use of reaching major part high pressure slurry filling anchor bolt effect, and O type sealing of hole powder stick device regulates hollow O type sealing of hole powder stick to be that blowing agent can shutoff armature boring simultaneously, plays isolated gas, water blockoff and prevent the effect of weathering;
3, the solid piston structure of the constant-resistance deformation device of perforation major part slip casting constant-resistance anchor pole can effective cushion impact forces, ensures integrality and the supporting intensity constant-resistance of supporting after buffering distortion;
4, the lengthening checkout gear of perforation major part slip casting constant-resistance anchor pole can lengthen on anchor (rope) bar tailing screw flight or screw thread anchor cable pressure lobe, instrumentation cover is installed to lengthen on connecting rod and detect stressing conditions, original anchor nut locking anchor pole after removal process dismounting lengthens connecting rod nut, stop that collection apparatus process anchor pole lost efficacy, rockbolt stress crosses big nut and eject and to hurt sb.'s feelings and instrumentation damages the problem such as cannot to change, this device can with common anchor (rope) bar with the use of the effect reaching anchor pole safety detection, recovery and replacing simultaneously;
5, the prolongation anchor cable device of perforation major part slip casting constant-resistance anchor pole can install prolongation anchor cable additional in constant-resistance deformation device termination, forms constant-resistance distortion anchor cable, improves anchor rod anchored scope and supporting bulk strength.
