Description
Technical field
The utility model belongs to construction technology in geotechnical engineering field, and in particular to a kind of vertical rock is bored.
Background technology
Rock drilling machinery, is the professional work that the current country is widely used for engineering the drilling construction and mine quarrying slab quarrying stone
Tool.Its Drilling on rock stratum goes out borehole, goes to blow rock to be put into explosive, so as to complete quarrying stone or other cubic meter of stone works
Journey.Conventional rock drilling machinery includes following several classes at present：
（One）, rock drill：Such a machinery is that, using bit shank strike, drill bit must be through drill steel from pricker to the strike work(of rock surface
Tail is transferred to acting position-bore bit or drill bit, with the intensification of drilling, and the growth strike work(of drill steel can be by the elastic shape of drill steel
Change is absorbed, and causes a large amount of losses for hitting work(, in addition, the exhaust mode that it is used is exhaust outside hole, that is after acting
Waste gas discharged outside hole, the waste gas of discharge still has larger compression potential energy, and this has resulted in the wave of mechanism energy itself
Take, outside the air-flow blowout hole that the aggregate chips produced by strike must be through drill steel centre bore, the center bore of general drill steel is Ф 8, this
Aperture is after drill steel length is more than 3 meters, and vapour lock increase causes not smooth, deslagging poor effect, it is impossible to effectively slag tap of ventilating, because
The Puncturing Limit depth of this rock drill is 3-5 meters.
（Two）, mountain region bore：Mountain region drilling tool has faster cutting rate and preferable rock drilling effect, and industry construction can be done in the wild
When it has unavoidable defect, be mainly reflected in the following aspects：1. unit volume is big, equipment overall weight is big（300-
1000kg）, therefore it is excessively poor in the complicated landform mobility such as mountain area, jungle, abrupt slope, workman takes in handling process, effort, danger
Dangerous coefficient is high, easily occurs personal injury；2. equipment needs to install support frame in work process（Pylon）Or vehicle frame is determined
Industry is done in position, and construction is laborious compared with complicated and time consumption, due to needing larger work top, substantially can not in forest zone and steep hills
Construction, can not even reach in more specifically shaped area and do industry point；3. because bit needs the extra rotation of offer to move
The device of power, the usually rotary motor mutually independent with gas impact machine or hydraulic gyration mechanism, therefore the overall energy of equipment disappears
Consumption is high, and recruitment quantity is big（The people of standard configuration 6）；
Also it can independently realize that impact rotating, the scale of construction are small and applicable without extra support, rig without a on the market at present
In the full-automatic rock drilling machinery of complicated landform.
The content of the invention

7th, swingle 12, connecting rod 13, the centre bore of drill bit 15 realize that bottom hole blows slag through to bottom hole, make outside rock slag tap；Separately
Gas enters the rear air cavity that piston body 11 is constituted with the back segment of cylinder 8 by the half-via of gas path distributor 7 all the way, with air inflow
Increase after air cavity pressure continue to increase, promote piston body 11 descending, the small end of piston body 11 enters guide sleeve 16 and closes guiding
The gas circuit closing of the bleeder port of set 16, at this moment preceding air cavity；Before 3rd road gas is entered by the air gap 14 of cylinder 8 and shell body 1
Air cavity, at this moment the bleeder port of preceding air cavity is in closed state, and with the air inflow increase of preceding air cavity, its air pressure also increases therewith
Plus, when the air pressure of current air cavity is more than rear air cavity, by the upward jack-up of piston body 11, now it is positioned on gas path distributor 7 valve
Piece 6 is opened by top, rear air cavity pressure release, and piston body 11 accelerates to run up, and the drawback movement of piston body 11 is realized, when piston body 11 connects
When closely running to rear air cavity top, the small end of piston body 11 departs from guide sleeve 16, and preceding air cavity opens exhaust, and preceding air cavity pressure release causes valve
Piece 6 switches, air cavity after connection, and gas constantly enters rear air cavity by the half-via of gas path distributor 7, when after air cavity pressure it is big
When preceding air cavity, the downward acceleration of piston body 11 realizes stroke movement until final strike drill bit 15, realizes broken rock.Now, by
Having been enter into air cavity before guide sleeve 16 is closed again in piston body 11 causes the pressure of preceding air cavity to be continuously increased, the pressure of current air cavity
During more than rear air cavity, the upward jack-up of piston body 11 is realized the drawback movement of piston body 11 by air pressure, completes a cycle period.It is living
When cock body 11 travels forward, the leading section of piston body 11 does impulsive motion, when piston body 11 is moved backward, piston body 11 to drill bit 15
The swivel nut 13 being inside embedded drives swingle 12 and the one-directional rotation of connecting rod 14, and then drives drill bit 14 to rotate, ratchet and pawl arrangement 9
Control drill bit 15 unidirectionally positioning and accurate indexing.What the vertical rock of realization was bored praises first 14 strike and rotational motion parallel, improves broken rock effect
Rate.
The characteristics of the utility model is maximum be：1. in use without extra support, it is only necessary to which early stage workman looks for
Quasi- punching place, helps vertical rock to bore punching certain depth downwards, vertical rock, which is bored, can voluntarily continue to continue to punch downwards, and traditional
Rock drilling machinery must build drilling cramp, not only expend huge, also limit the operating environment of punching.2. piece tracheae of a need provides dynamic
Power can complete two work of drill bit impact and bit, and traditional rock drilling machinery typically uses Pneumatic immpacting, electronic rotation, sheet
Utility model is greatly saved the consumption of the energy, enormously simplify the labyrinth of traditional rock drilling machinery.3. because this practicality
New is simple in construction, lightweight, is easy to carry to different different areas of activity, is not limited by complicated landform, scope of application pole
It is big to expand.4. the utility model is guarded without personnel, multimachine series connection common operational, perforating efficiency can be shunted by a tracheae
Injury of the dust during rock drilling to staff is avoided while high.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and any equivalent conversion taken technical solutions of the utility model, are claim institute of the present utility model
Cover.
