Description

Rotary drilling rig down-hole hammer construction Special working device
Technical field
The utility model relates to a kind of down-hole hammer Special working device, specifically a kind ofly drives with whole down-hole hammer and the rotary drilling rig of transmission device, belongs to rotary drilling rig down-hole hammer drives structure technical field.
Background technology
In rotary drilling rig construction, catalase mainly belongs to and shears into rock, and according to the condition of rock shearing fragmentation, rotary drilling rig must possess the high rigidity of high pulling torque, the large plus-pressure effectively transmitted and drilling tool pick and abrasion resistance three factor greatly to realize entering rock smoothly.But due to the restriction of rear two factors, rotary drilling rig efficiency of construction under hard rock operating mode is extremely low; And because the reaction force fluctuation of stratum to equipment is large, and peak value is high, larger to the structural member fatigability infringement of equipment.
Drilling Technology of Airdriven DTH Hammer is the more a kind of drilling technology of domestic and international application, also be the important breakthrough of air drilling technology in detritus method, it is mainly dynamic medium with compressed air, and utilizing compressed-air actuated energy to produce power equipment at the bottom of the hole of repetitive shocks, compressed air can double as hole flushing medium simultaneously.Under usual condition, pneumatic down-hole hammer is directly connected to impact mode detritus with hard alloy columnar teeth drill bit, and low speed turns round total cost management of not coring.If pneumatic down-hole hammer and rotary drilling rig are supported the use, not only can increase substantially drilling efficiency but also hole quality is better, construction cost is low, be suitable for the Rock penetrating of more than medium hardness, particularly creep at competent bed.
Existing pneumatic down-hole hammer divides direct circulation down-hole hammer and reverse circulation down-the-hole hammer, and generally, direct circulation down-hole hammer uses direct circulation construction technology, and reacting cycle hammer uses reverse circulation construction technique.Direct circulation construction technology refers to that driving drilling rod and drill bit to turn round by rig slewing equipment cuts broken ground, then is input into mud from slush pump toward drilling rod, and mud rises along drilling rod hole wall, overflows and flows into mud pit, return circulatory pool through precipitation from aperture.Reverse circulation construction technique refers to that driving drilling rod and drill bit to turn round by rig slewing equipment cuts broken ground, then utilize the measure suction circulation slurry coat methods such as pump suction, gaslift, injection, carry boring mud secretly from the hole forming method drilling rod inner chamber sucking-off hole.
By rotary drilling rig and down-hole hammer with the use of time, due to the design of triple channel structure difficulty, and reverse circulation down-the-hole hammer aperture is less on market, most great talent about 0.3 meter, and direct circulation down-hole hammer largest diameter can to 2 meters, therefore reverse circulation down-the-hole hammer cannot adapt to revolve drilling construction requirement, only have direct circulation down-hole hammer can with rotary drilling rig with the use of.But construct according to direct circulation construction technology, for preventing collapse hole during construction, must arrange full casing sleeve pipe follow-up construction, so not only increase cost, and institute's deslagging is not easy to collect, environment pollution is larger.Utilize reverse circulation construction technique to carry out deslagging and can solve the problem that direct circulation construction technology brings, but how to realize reacting cycle construction when constructing large aperture with direct circulation down-hole hammer be the difficult point that pile foundation industry is not broken through always.
In addition, traditional pneumatic down-hole hammer device is that unit head upper and lower side received respectively by drilling rod and water tap, drives drilling rod by unit head, and on water tap, transfer port and investigation hole are transformed in drilling rod by unit head.Though this structure also can realize rotary drilling rig and pneumatic down-hole hammer with the use of, unit head is changed comparatively large, can not realize common revolving very easily and to dig and pneumatic down-hole hammer revolves the switching between digging.
