Description
Technical field
The churning driven machine drill of anti-fall device is housed the present invention relates to a kind of drilling machine drilling rod, more particularly to a kind of core pole
Bar.
Background technology
Rotary drilling rig in construction process, its drilling rod length need to differ according to construction requirement, and its length can basis
Need to be adjusted, by the way of Multi section bar pipe layer overlaps and clamping.Because in the course of the work, drilling rod can be born simultaneously
The combined stresses such as shearing, torsion, pressurization, so in the work progress such as highway, railway, bridge, skyscraper, due to behaviour
Mass defect in author's misoperation or manufacture, causes most one pole of the inside in work progress（Hereinafter referred to as core pole）Lower end
Often there is phenomenon of rupture, cause square toes position to fall into stake holes, salvage extremely difficult, even can not salvage sometimes and influence whole
The construction of individual engineering.Chinese patent CN200975221Y and CN201666123U disclose one kind and can prevented under core pole
There is the drilling machine drilling rod for being broken and causing square toes position to fall into stake holes in end, and they are all by being set inside core pole
The flexible steel wire or metallic bond of spade terminal and square knuckle is connected to avoid drill bit from falling into stake holes in drill rod breaking.But by
Top rod still can spin for some time, therefore would generally be right at a relatively high speed before fracture is found when drill rod breaking
The flexible steel wire or metallic bond of connection produce larger torsion, and this may damage flexible steel wire or metallic bond or even lead
Cause them to be broken.Further, since after drill rod breaking, two sections of fracture are connected against flexible steel wire or metallic bond, drilling rod and brill
Head is no longer that a rigidity is overall, and bit part is generally very heavy, therefore when drilling rod is pulled out into stake holes using lifter,
Due to the effect of frictional force, drill bit is easily swung laterally, and then damage stake holes even results in landslide.
The content of the invention
It is contemplated that overcome drawbacks described above there is provided a kind of core pole be equipped with anti-fall device drilling machine drilling rod, specifically
Ground, including provided with the section rod tube that layer overlaps are set outside conventional structure homalocephalus, the core pole of square toes and core pole, core pole body
Driving key is provided with surface, body is provided at both ends with the connector that square toes are connected with middle part in homalocephalus or drill pipe,
Connector is divided into two sections, and this two sections are connected by swivel joint.
Preferably, connector is iron chain, steel wire rope or metallic rod.
Preferably, the swivel joint is the ball-and-socket joint by ball joint, it include with protrusion spheroid on connect
Head and the lower contact with ball recess, top connection cooperatively form ball-and-socket joint with lower contact.
Preferably, top connection is connected to the bottommost of homalocephalus or lower contact is connected to the topmost of square toes.
Preferably, the swivel joint is single direction rotation joint.
The invention further relates to a kind of method for taking out drilling machine drilling rod when being broken, it utilizes the reverse drive for driving key
Post-rift bottom drilling rod and bit are driven, the drilling rod of fracture is taken out using lifter.
Preferably, the speed of driving key driving drilling rod rotation is proportional to the lifting speed of lifter.
Preferably, in the above-mentioned methods, the connector in core pole is iron chain, steel wire rope or metallic rod.
The infringement for connector, Jin Ergeng can be reduced using according to the anti-fall device with swivel joint of the present invention
Plus effectively act as protective action；Meanwhile, when using single direction rotation joint, it can be more conducive to according to the anti-fall device of the present invention
The taking-up of drilling rod is broken, the security of stake holes is protected.Moreover, the anti-fall device with swivel joint of the present invention allows metal
Bar is used as connector.
Brief description of the drawings
Fig. 1 is the structural representation of the drilling machine drilling rod according to the present invention；
Fig. 2 is the core pole structural representation equipped with anti-fall device according to the present invention；
Fig. 3 is the connection diagram of the anti-fall device according to the present invention.
Embodiment
Referring to Fig. 1 and 2, according to the drilling machine drilling rod of the present invention, including the core section provided with conventional structure homalocephalus 1, square toes 3
The section rod tube 2 of layer overlaps is set outside bar 4 and core pole.Driving key 5, the pipe two of core pole 4 are provided with the tube surfaces of core pole 4
End is provided with the high intensity connector 6 that square toes 3 are connected with middle part in homalocephalus 1 or drill pipe, for example, can use high intensity
The objects such as iron chain, steel wire rope or metallic rod.Preferably, high-strength iron chain of the present invention, steel wire rope or metallic rod
It is not complete overall structure, but two sections connected by a swivel joint, the swivel joint can be logical
The ball-and-socket joint of ball joint is crossed, as shown in figure 3, it is included with the top connection 11 for protruding spheroid and with ball recess
Joint 12, top connection 11 cooperatively forms ball-and-socket joint with lower contact 12, and top connection 11 can carry out freedom relative to lower contact 12
Rotation.Certainly, top connection 11 will be enough to bear drill bit and be broken the weight of drilling rod with the cooperation dynamics of lower contact 12.In addition, here
Swivel joint can also use other various ways, only need to meet cooperation dynamics enough and can freely rotate against.
Preferably, top connection 11 may connect to the bottommost of homalocephalus 1 or lower contact 12 is connected to the topmost of square toes 3, so can be with
Tie point is saved, now high-strength iron chain, steel wire rope or metallic rod can keep complete overall structure.
In another embodiment, according in the anti-fall device that is used of core pole 4 of the drilling machine drilling rod of the present invention
Swivel joint only allow rotating against for single direction for single direction rotation joint, the i.e. joint, similar to the flywheel of bicycle
Structure, its outer ring can only rotate relative to wheel shaft to single direction.Single direction rotation joint in the embodiment only allows to be same as boring
During machine normal work（It is not broken）Drilling rod direction of rotation, that is, top connection can only be with relative to the direction of rotation of lower contact
Drilling rod direction of rotation is identical during rig normal work.So, in drill rod breaking, the lasting rotation of top rod will not the company of torsion
Junctor 6；And when drilling rod is pulled out stake holes by lifter, it is possible to use the reverse drive of driving key 5 drives post-rift bottom to bore
Bar and bit, can thus reduce drill bit to the hurtful risk of stake holes so that drill bit is easier to beat from stake holes
Pull out.Preferably, the connector 6 in the embodiment can use rigid metal bar, the transmission for being so conducive to power to refuse.Preferably,
Now, the speed of driving key 5 driving drilling rod rotation is proportional to the lifting speed of lifter.
The infringement for connector, Jin Ergeng can be reduced using according to the anti-fall device with swivel joint of the present invention
Plus effectively act as protective action；Meanwhile, when using single direction rotation joint, it can be more conducive to according to the anti-fall device of the present invention
The taking-up of drilling rod is broken, the security of stake holes is protected.
Those skilled in the art can be according to present disclosure and the art technology grasped in the present invention
Appearance makes replacement or modification, but these are replaced or modification is all not regarded as a departure from present inventive concept, and these are replaced or modification
In claimed interest field.
