Abstract
A kind of novel rotary digs into rock construction specific drilling tool, drilling and forming hole suitable for rock soil, it includes the connector that drilling tool is connected with drilling rod, connector is provided with preformed hole, it is characterized in that boring specific side is provided with steam vent, bores specific opposite side and be provided with some wear ribs, bore specific end and be provided with base, pick is inlaid in base, and base axis and drilling tool body axis are in 30 ° of 35 ° of angles.The optimal entrance angle of base control pick and scar of the present utility model, wear rib protection drilling tool body, improves drilling tool wear-resistant, steam vent is easy to drilling tool deslagging to outside hole.The utility model drilling tool can be used for multiple times, and enter rock work efficiency height, save the engineering time, construction cost is low.
Description
Technical field
Rotary digging drilling and forming hole of the utility model suitable for rock soil, and in particular to rotary digging drilling hole bored concrete pile one kind enters rock
The new exclusive rotary drill tools of construction.Led applied to engineerings such as building construction, municipal administration, water conservancy and hydropower, petroleum and petrochemical industry, road and rails
Domain is built（Structure）Build thing ground rotary digging and enter rock drilling construction.
Background technology
Rotary drilling rig enters rock construction specific drilling tool and ensures pick and scar by controlling the angle β of pick base and drilling tool
Entrance angle at 30 ° -35 °, after entering rock, drilling tool pick is extruded by drilling rod and cuts rock, unit head drives drilling rod rotation to cut
Enter drilling tool rock with basement rock disengaging and band to portal outside.
Existing rotary digging enters rock drilling tool, including body open type and spiral, ignores pick entrance angle β, and drilling tool form for
Enter rock drilling it is unreasonable, pick serious wear, consumptive material are big in drilling, construction effect is low, construction cost is high.
The content of the invention
Enter rock constructional difficulties to solve rotary drilling rig, the problem of speed of application is slow, cost is high, the utility model provides one
Kind rotary drilling rig enters rock construction specific drilling tool.
A kind of novel rotary digs into rock drilling construction specific drilling tool, including the connector that drilling tool is connected with drilling rod, on connector
Provided with preformed hole, it is characterized in that boring specific side is provided with steam vent, bores specific opposite side and be provided with some wear ribs, drilling tool body
End be provided with base, pick is inlaid in base, and base axis and drilling tool body axis are in 30 ° of -35 ° of angles.
The specific length of brill is 1400mm.
The preformed hole aperture is 40mm.
The wear rib is 4.5 × 80 × 500mm straight carbon steel rimmed steel sheets.
The steam vent is 100mm × 250mm slots.
The base is cylinder.
The base is made up of RG85 alloy materials.
The utility model controls the optimal entrance angle of pick and scar by base, wear rib protection drilling tool body, improves
Drilling tool wear-resistant, steam vent are easy to drilling tool deslagging to outside hole.
Operation principle of the present utility model：Using coulomb-Na Weier criterions, the ultimate shearing strength of rock is only that the limit resists
10% or so of Compressive Strength, the most effectual way for drilling into rock are exactly to shear broken rock.The utility model is by controlling pick datum axle
Line is with drilling tool body axis angle β at 30 ° -35 °, and after entering rock, the entrance angle of pick and scar is β, and drilling tool is extruded by drilling rod
Pick incision rock occurs to shear broken rock, then drives drilling rod rotation that incision rock is departed from into simultaneously band with basement rock by unit head and portal
Outside.
The utility model drilling tool can be used for multiple times, and enter rock work efficiency height, save the engineering time, construction cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, preformed hole, 2, steam vent, 3, wear rib, 4, base, 5, pick.
Embodiment
Shown in Fig. 1, the utility model is made up of drilling tool body, base 4, pick 5, is bored specific top and is connected with connector,
Connector is provided with preformed hole 1.
At the top of drilling tool body five are welded with rotary drill rod by the preformed hole and pin connection on connector, drilling tool body side
Wear rib 3, the opposite side indwelling steam vent 2 of 4.5mm × 80mm × 500mm straight carbon steel rimmed steel sheet material, under drilling tool body
Came welds some bases 4, and base axis are in 30 ° of -35 ° of angles with boring specific axis；Pick 5 is installed in base 4.
The cylinder that specially height is 1400mm is bored, the aperture of preformed hole is 40mm, and steam vent is 100mm × 250mm
Slot, base is RG85 alloy round seats.
The base is cylinder.
