Description

The quick-changing type single-cone rotary drill bit of rotary drilling rig core drill bit special use
Technical field
The utility model relates to drill bit of drilling machine field, the quick-changing type single-cone rotary drill bit of specifically a kind of rotary drilling rig core drill bit special use.
Background technology
At present, in pile foundation engineering field, all use to revolve and dig stake, revolve dig stake need to adopt rotary drilling rig pile, when excavation hardpan (hard rock), need be by the higher core rock bit of efficiency, gear wheel in the rock bit of using is at present to use the tricone bit that oil drilling is used, and this drill bit is in oil drilling industry extensive use, and its manufacturing technology is comparative maturity also.But its structure can not be applicable to revolve completely, dig drill bit, due to tricone bit three-wheel one, need to be divided into monomer to it, then be welded to revolve and dig on drill bit.
In actual use, its shortcoming is as follows:
1, tricone bit is applied to revolve and digs on drill bit, its unreasonable structure.
2, due to it will be cut apart, as remove its be threaded part and water jet part, can cause the waste of material.
3, the gear wheel after cutting apart with revolve the welding manner that is connected to that digs drill bit, gear wheel wearing and tearing or damage after change very inconveniently, waste time and energy, duration progress is impacted.
4, because job site does not have rivet welding platform, and be subject to the restriction of technical condition, gear wheel cutting angle and size after replacing cannot guarantee, greatly reduce the drilling efficiency of drill bit, affect duration progress, have increased construction cost.
While 5, welding, easily the sealing of gear wheel inside and Fuel Tanking Unit are caused to damage, thereby reduced the application life of gear wheel.
Utility model content
The purpose of this utility model is in order to address the above problem, designed the quick-changing type single-cone rotary drill bit of a kind of rotary drilling rig core drill bit special use, this drill bit structure is simple, exempt from welding, easily install, the shortcomings existing at the rotary drill of use at present to solve rotary drilling rig, thus the operating efficiency of rotary drilling rig improved, reduce construction cost.
Realizing above-mentioned purpose the technical solution of the utility model is, the quick-changing type single-cone rotary drill bit of rotary drilling rig core drill bit special use is characterized in that, structure consists of cone palm, mount pad, gear wheel, roller axle, pressing plate, accumulator,
Cone palm, gear wheel, roller axle, insert in the chute of mount pad with tapering by the boss of cone palm both sides as single-cone rotary drill bit main part, form fixing and locking structure and connect, and with bolt, be fixed in cone palm both sides with pressing plate.
As preferably, the bottom of described cone palm and roller axle are vertically installed with circular hole accumulator.
The utility model beneficial effect:
The utility model cone palm changes tapering chute into by original thread connecting mode and inlays connected mode, and at the mount pad of drilling pipe barrel soldering fluting, cone palm inserts in mount pad chute, pressing plate, bolt-locking for end face.
Compare with the rotary drill of cutting apart at three gear wheels of use at present:
(1) on project organization, more meet the operating principle of drilling bit of rotary-digging drilling rig;
(2) avoid the welding of cone palm main body, protected sealing system and accumulator not to be damaged, extended the application life of gear wheel;
(3) after gear wheel wearing and tearing or damaging, more convenient during replacing, quick;
(4) due to the existence of mount pad, the gear wheel setting angle after replacing can not change, not high to the technical requirements of replacing installation personnel, can not affect stock-removing efficiency.
Accompanying drawing explanation
Fig. 1 is single-cone rotary drill bit structural representation described in the utility model;
Fig. 2 is the installment state figure of single-cone rotary drill bit described in the utility model on drilling pipe body;
In figure, 1-cone palm, 2-mount pad, 3-gear wheel, 4-roller axle, 5-pressing plate, 6-bolt, 7-accumulator, 8-drill bit cylindrical shell.
the specific embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, as shown in the figure, the quick-changing type single-cone rotary drill bit of rotary drilling rig core drill bit special use, is characterized in that, structure consists of cone palm 1, mount pad 2, gear wheel 3, roller axle 4, pressing plate 5, accumulator 7,
Cone palm 1, gear wheel 3, roller axle 4, insert in the chute of mount pad 2 with tapering by the boss of cone palm 1 both sides as single-cone rotary drill bit main part, form fixing and locking structure and connect, and with bolt 6, be fixed in cone palm 1 both sides with pressing plate 5.
As preferably, the bottom of described cone palm 1 and roller axle 4 are vertically installed with circular hole accumulator 7.
In the present embodiment, cone palm 1 changes tapering chute into by original thread connecting mode and inlays connected mode, and at the mount pad 2 of drilling pipe cylindrical shell 8 welding flutings, cone palm 1 inserts in mount pad 2 chutes, pressing plate 5, bolt 6 lockings for end face.
In the present embodiment, revolve and dig drill bit cylindrical shell 8 end flutings, mount pad 2 is welded on fluting both sides, and cone palm 1 inserts in the chute of mount pad 2 with tapering, and is fixed at cone palm 1 both sides bolt with pressing plate 5.Mount pad 2 adopts high-abrasive material and heat-treats, and in use abrasion resistance is good, not fragile.The rock bit of change damaging only need be unloaded lower platen, extracts cone palm out, new gear wheel insertion, cone palm without with barrel soldering, it is very convenient to change.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
