Description
Technical field
Construction Technology field is the utility model is related to, specifically a kind of drilling tool of four wings alloy bit.
Background technology
With my economic fast development, the continuous expansion of city size, the continuous reinforcement utilized to the underground space,
Deep-foundation pit engineering and Geotechnical Engineering are also more and more.Enter rock drilling tool because of its convenient construction, speed, need not largely work
Power, current market widely use the drilling tools such as three leaf drill bits and down-hole hammer.But because three leaf drill bits employ commonly on material
Steel, cause to wear no resistance and the proportion of goods damageds are very high, can only be constructed in general soil property region, it is impossible to carry out into rock drilling, it is necessary to
Construction operation could be continued by changing down-hole hammer.But down-the-hole hangs down and can not applied in general soil property, and down-hole hammer is made in deep hole
Shake larger during industry, soil layer, which easily caves in, behind drill bit causes down-hole hammer to be embedded in hole, can only be whole in combination with set pipe construction
Individual work progress process is numerous and diverse, and mechanical loss rate is high, and cost is larger.Therefore, in order to promote accelerate site operation progress needs
And construction cost is reduced, find a kind of more easily construction method and be particularly important.
The content of the invention
Traditional drilling tool that the utility model is mainly solved in land and rock combination geological drills high loss into rock, high cost, work
Sequence is numerous and diverse, efficiency is low and can not tackle the uncertain problem of some ground, on the premise of not increase expense, there is provided a kind of
Four convenient, efficient, inexpensive and durable wing alloy bits.
To achieve these goals, a kind of drilling tool of four wings alloy bit, including annular fixed seat, described ring are devised
Shape fixed seat by annular connecting portion suitable for reading, under the symmetrical otch of intraoral threaded joints and middle part form, lower mouth threaded joints
Inside is used for jointed rod for screw thread hollow and in a concave shape.
Four described wing alloy bits are provided with drill bit inclined-plane sword, and drill bit inclined-plane sword is by cutting edge and anistree alloy welding hole group
Into being uniformly distributed anistree alloy welding hole on cutting edge.
Four described wing alloy bits are provided with anistree carbide button, and anistree alloy tooth outline is that eight prisms are suitable for reading into 25 ° of otch.
Four described wing alloy bits are provided with alloy chisel teeth, and alloy wedge shape tooth outline combines shape with cylinder in circular cone, circle
Bore suitable for reading wedge shaped.
The utility model patent compared with the existing technology, the utility model cutting principle be by several carbide button heads,
Similar tooth equally carries out the broken rock that bites to rock mass, and drag reduction is lubricated by the water injection hole injected clear water of annular fixed seat end
And cooling, it is overall tapered, cut that the contact surface of rock mass is big, and cutting speed is fast, suitable for the drilling that aperture is larger, its advantage exists
In：This drilling tool is provided with four drill bit inclined-plane swords, and cutting edge is provided with anistree carbide button, and anistree carbide button is suitable for reading unanimously towards meeting soil
Face, while top is provided with an alloy chisel teeth, enhances the efficiency that drill bit enters rock, has greatly reinforced its durability, reduces
Mechanical loss rate, reduces production cost.
Brief description of the drawings
Fig. 1 is floor map of the present utility model.
Fig. 2 is top view of the present utility model.
In figure：1. the drill bit inclined-plane sword of 3. alloy chisel teeth of anistree 2. annular fixed seat of carbide button 4..
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure and principle of this drill bit people professional to this
For be very clear.It should be appreciated that instantiation described herein is not used to only to explain the utility model
Limit the utility model.
Referring to Fig. 1 and Fig. 2, four wing alloy bits include annular fixed seat connecting portion suitable for reading and weld four drill bit inclined-plane swords,
Under intraoral threaded joints jointed rod, drill bit inclined-plane sword axle centered on annular fixed seat adjacent part shape in 90 °.Every brill
Head inclined-plane sword cutting edge is uniformly distributed anistree carbide button welding hole with axis, and anistree carbide button is arranged in welding hole, while eight
Angle carbide button is suitable for reading unanimously towards native face is met, and strengthen drill bit enters rock efficiency.Alloy chisel teeth is embedded in four drill bit inclined-plane swords
Intersection location suitable for reading.
This drilling tool process for using is as follows：
1. poise drilling tool：According to rig type selecting and the supporting drilling tool of drilling rod；
2. rig is in place：Drilling-machine shifter is to the hole position, and workbench is adjusted to horizontality, and support frame keeps stable；
3. four wing alloy bits are installed：Intraoral threaded joints under four wing alloy bits are connected with drilling rod top；
4. enter rock operation：The tip of four wing alloy bits is directed at ready-made mark, perforate operation is then carried out, in operation
Being continuously increased installation drilling rod ensures that hole depth reaches design load；
5. pore-forming is put away sports equipment：After hole depth reaches design load, drilling rod exits until four wing alloy bits leave aperture section by section, drilling
Process is completed, and down-the-hole drill is moved to next mark point position.
