Description
Technical field
The present invention relates to technical field of fluid transmission, in particular to a kind of fluid reversing structure and gas-liquid impactor
Mechanism.
Background technology
Impactor, a kind of drilling project need infrastructure device to be used, are generally divided into two kinds：
Hydraulic impacter, also known as hydraulical impact rotary drilling bits, hydraulic in-the-hole hammer, hydraulic hammer.With drilling fluid and hydraulic pressure
Oil is dynamic medium, utilizes high pressure liquid stream energy and the bottom hole power equipment of dynamic water attack energy production repetitive shocks.It is logical
Drilling tool top is directly often bound up on, while rotary drilling, continuous shock loading is transferred on drill bit, makes drill bit to return
Turn cutting and impact two ways joint fractured rock.For geological drilling, engineering construction is particularly suitable in hard, kata-rocks
It is applied in layer and medium-hard coarse grain unevenness homogenous rock stratum.
Air hammer, also known as pneumatic dth hammer, pneumatic down hole hammer.It is empty using compression using compressed air as dynamic medium
The bottom hole power equipment of the energy production repetitive shocks of gas.Compressed air can double as hole flushing medium simultaneously.Pneumatic immpacting
Device is divided into high wind pressure and low wind pressure, valve type and no-valve type.Usual air hammer is directly connected with hard alloy columnar teeth drill bit
The detritus in a manner of impacting, low speed turn round total cost management of not coring.Be mainly used in hydrology and water well drilling, without rock core geological drilling,
The fields such as hazards control engineering and mine drilling.Existing impactor feature：(1) pressure duty, spring reset, (2)
Pressure resets, and spring force work, (3) pressure resets, and falls generation impact force by piston dead weight, changement is set outside (4),
Defect：(1) impact force is small, impact force be reversed power offset significant portion, (2) impact stroke is longer, high energy consumption, overall dimensions compared with
Greatly, set changement volume big outside (3), it is complicated, it can not be used as bottom hole drilling tool.(4) piston dead weight impact force
Small, efficiency is low.
The content of the invention
The present invention first be designed to provide a kind of fluid reversing structure, the fluid reversing structure be applied to probing and
Peripheral hardware changement and two-way supply or liquid is not required in engineering field, the fluid reversing structure simple structure, can be effectively
It is energy saving.
Second object of the present invention is to provide a kind of gas-liquid impactor mechanism, which has above-mentioned fluid
Commutating structure can be effectively energy saving, is not required additional accumulating mechanism two-way and generates impact force by gas-liquid pressure, does not have pressure damage
Mistake and Efficient Operation.
What the embodiment of the present invention was realized in：
A kind of fluid reversing structure, including：
Base cylinder, base cylinder have opposite first end and second end, and the inside of base cylinder has stroke cavity, and first end, which has, to be connected
