Description
Technical field
The utility model relates to a kind of rotary drilling rig drilling tool.
Background technology
Along with the high speed development of global economy, the continuing of infrastructure scope widened, and what people-oriented and protection environment concept and relevant laws and regulations are implemented continually strengthens, make pile foundation particularly the on-site concrete bored concrete pile foundation obtained using widely.Rotary drilling rig because of its efficient height, pollute less, flexible, the many characteristics of function combination, adapt to the demand of composite development, occupied the position of main force's type in the cast-in-situ concrete poured pile driving construction at home and abroad.Rotary drilling rig generally is applicable to clay, silt, sand, mucky soil, artificial backfill and contains the stratum of part cobble, rubble.Rig for having high pulling torque unit head and automatic inner locking type telescopic drill rod can adapt to the construction of gentle breeze hard rock.In order to satisfy construction requirement, characteristics such as the configuration of rotary drilling rig chassis and equipment has that installed power is big, output torque big, maneuverability, multi-functional, efficiency of construction height.At present, the maximum drilling diameter of rotary drilling rig is 3m, and maximum drilling depth reaches 120m, and maximum boring moment of torsion is 620kNM.
Find through literature search prior art, present relevant both at home and abroad patent about the rotary drilling rig aspect, domestic about 130, external about 160, make a general survey of these patents, as can be seen, the patented technology of rotary drilling rig focuses mostly in the rotary drilling rig that has a new function, drilling rod and drilling tool, next is a control system, is only construction at last.Aspect drilling tool, mainly contain now that precious pretty young woman drags for that sand drilling tool, pick drag for the sand drilling tool, tube bores and auger etc.But rotary drilling rig particularly enters competent bed after entering the rock stratum, creep into difficulty, and rotary drilling rig penetralia drilling rod can't bear powerful torsional forces and fatigue effect because the bar footpath is little, often causes drill rod breaking, and simultaneously, the square toes place also is prone to the phenomenon that fractures.And at present the super deep pile foundation of super large is more and more, the long 80m of stake occurs, more even 100m, and so dark, conventional diving person can't carry out operation, can't salvage success as drilling tool and then can cause the pile foundation quality accident.Therefore, drilling tool design helps fishing and has great importance.
The utility model content
The purpose of this utility model provides salvages the rotary drilling rig drilling tool, solve in work progress can't utilize the new clothes drilling tool itself to salvage, cause easily the technical problem of pile foundation accident after the common drilling tool fracture.
For achieving the above object, the utility model adopts following technical scheme:
Salvage the rotary drilling rig drilling tool; comprise by up-small and down-big circular platform type and bore wall; the drill body that base plate and top board are enclosed; the backplane switch device is arranged in the described drill body; described circular platform type bores and has the slurry hole of overflowing on the wall; the wall of boring guard shield is arranged at its outer wall bottom; there is the pick that is positioned at base central authorities described base plate bottom surface and precious pretty young woman's bucket tooth spaced apart on base plate; described top board is connected with the square toes Connection Block; the rectangle tetrahedron of described square toes Connection Block for enclosing by four blocks of square toes plates; described top board is put together relatively by the trapezoidal steel plate minor face of two block length sideband arced terminus; its hypotenuse of described top board upper edge is provided with oblique stiffener on the plate; on every block of plate tiltedly the sustained height position of stiffener have circular hole; reeve in the described circular hole; the end of wire rope is fixed by fastener, described top board soffit be provided with plate on tiltedly under the corresponding four blocks of plates in stiffener position oblique stiffener and one cross horizontal stiffener under the elongated plate of the square toes Connection Block bottom surface centre of form.
The diameter of described wire rope is h+300mm, and h is the width of the square toes plate of square toes Connection Block.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The one, the utility model passes through to increase safety rope at the drilling tool top, can transfer to salvage to collude and carry out the drilling tool salvaging.
The 2nd, the utility model has both strengthened intensity, the rigidity of top board by the arrangement of stiffener about the top board of common drilling tool is adjusted, and also helps the enforcement of other multiple salvaging schemes.
The 3rd, the utility model has made things convenient for and has salvaged transferring and pull-up of colluding when salvaging operation by the rectangular-shaped top plate in the common drilling tool being changed into the shape of two trapezoidal steel plate minor face butt joints.
The 4th, the utility model is simple in structure, transforms ingeniously, can transform saving of work and time at the construction field (site) voluntarily.
The utility model can be widely used on the rotary drilling rig, especially needs to carry out on the rotary rig of dark pile driving construction.
