Description
Technical field
The present invention relates to a kind of drilling equipment, specifically one be applicable to underground coal mine roadway floor carries out anchor pole of holing
The coal mine down-hole tunnel steady boring device of base plate armature boring of supporting, belongs to down-hole support equipment technical field.
Background technology
Due to the self-characteristic of different depth rock mass and the difference of residing ambient stress around tunnel, transported by geologic rhythm
The factor impacts such as dynamic, ground water pressure, country rock easily produces Incoordinate deformation, exploits especially for underground coal mine, top, tunnel, the end
Plate and two helps country rock to be deformed and move in tunnel, and the phenomenon that wherein roadway floor or gob floor upwards swell is i.e.
Referred to as pucking, pucking is a kind of dynamic phenomenon often occurred in roadway, it and the character of country rock, mining influence, mining depth
And geological structure etc. is directly related, some Floor Heave in Roadway amount of domestic mine even account for top, tunnel, the base plate amount of shifting near 70% with
On, bigger particular for mining depth, have that stress is high, temperature is high, subsoil water hydraulic pressure is high, strength of turbulence is high, danger of burst
The deep-seated setting of feature, high stress and soft rock mine roadway and the chambers such as height, creep is obvious, deformation is big, pucking makes roadway deformation, section become
Little, drastically influence the links such as mine ventilation, transport and personnel's walking, restriction mine safety and high-yield and high-efficiency and produce.
Underground coal mine prevents the generation of pucking phenomenon from not only wanting reinforcement roadway support, reinforced design method, and will be according to specifically
Wall rock geology condition take measures pucking amount is reduced to allowed band, generally use method for strengthening, destressing method, combination method and add
Gu the methods such as tunnel side, angle reduce pucking phenomenon, wherein method for strengthening is to be enclosed base plate by raising floor rocks intensity or raising
The supporting power of rock reaches the purpose of floor lift control, is a kind of the most frequently used pucking control method.
Improve the intensity of floor rocks, mainly have floor grouting, floor bolting etc., base plate is being used suspension roof support
Needing during operation first to hole base plate, traditional method need to be with pin or reversely air leg support above drilling rod in boring procedure
On back, to provide reverse holding power, but due in order to ensure that roadway floor does not destroys before installing anchor pole, it is necessary to
Installing anchor pole in driving face certain distance, the size of this distance is relevant with the character of floor rock, typically should be little
In 10 meters, the most unaffected in order to ensure tunnelling speed, the speed of usual rockbolt installation wants fast, and this traditional brill
Hole method operation not only complicated, manpower and materials consume big, and hole and install the speed of anchor pole compared with slow, efficiency is low, inadaptable
Requirement in Quick Road-Made.

In order to alleviate the overall weight of whole device so that moving, scheme as a further improvement on the present invention, described
Underframe 1 and added 3 be all frame structure.
In order to increase the integrated support intensity of this equipment, scheme as a further improvement on the present invention, described underframe 1
And/or the frame structure two sides of added 3 are provided with supporting rib stiffener arranged in a crossed manner.
In order to realize positioning and locking nut 23 and location, left and right before and after not using additional means quickly to screw or unclamping location
Locking nut 25, as a further improvement on the present invention scheme, positioning and locking nut 23 and location, left and right before and after described location
Handle radially it is provided with, before and after can realizing manually quickly screwing or unclamping location by rotary handle on locking nut 25
Positioning and locking nut 23 and left and right positioning and locking nut 25.
In order to prevent before and after the location after screwing positioning and locking nut 23 and left and right positioning and locking nut 25 at boring procedure
Middle loosen because of vibration, scheme as a further improvement on the present invention, described before and after positioning and locking nut 23 inner face with
Between the lateral surface of the guide groove 22 and outside of inner face and left and right guide groove 24 of left and right positioning and locking nut 25 front and back
Between face, ecto-entad is sequentially provided with spring washer and plain washer.
The steady boring device of this coal mine down-hole tunnel base plate armature boring is owing to being provided with added 3 be arranged on underframe 1, and top is fixed
Position supporting cylinder 41 and control valve group 43 are arranged on added 3, and location, bottom supporting cylinder 42 is arranged on underframe 1,
Therefore being manipulated by valve group 43 makes top location supporting cylinder 41 and location, bottom supporting cylinder 42 stretch out respectively, top
The support footstock of location, portion supporting cylinder 41 acts against on top board, the support base of location, bottom supporting cylinder 42 acts against
Making underframe 1 form stable rigid support between back and base plate on base plate, during boring, the drilling rod of rig 27 pierces
The counteracting force that base plate produces acts on underframe 1 by rig installing rack 26, body 21, and underframe 1 is fixed by top by active force
Position supporting cylinder 41 and location, bottom supporting cylinder 42 directly act on back and base plate, therefore need not at rig
It is supported on back to provide reverse holding power with pin or reverse air leg above the drilling rod of 27;Owing to workpiece 2 sets
There are before and after's guide groove 22, front and back positioning and locking nut 23, left and right guide groove 24, left and right positioning and locking nut 25, therefore will
The steady boring device of this coal mine down-hole tunnel base plate armature boring can realize after having good positioning pinpointing a position can complete multiple rows of or
The operation in multiple row hole, i.e. can realize rig 27 owning in front and back's guide groove 22 and left and right guide groove 24 stroke range
The bore position of full line and permutation carries out location boring;Due between body 21 and underframe 1, rig installing rack 26 and body 21 it
Between be equipped with cylindricality piston shoes, therefore can realize on fore-and-aft direction or left and right directions non-fully the roadway floor of level hang down
Straight boring;This coal mine down-hole tunnel base plate armature boring steady boring device simple in construction, easily operated control, after completing boring
Carry out rockbolt installation, hole and the speed of anchor pole, installation effectiveness height are installed, being adapted to the requirement of Quick Road-Made, the suitableeest
