Description
Technical field
The invention belongs to technical field of buildings, it is related to a kind of drilling rod, more particularly, to a kind of retractable rod for drilling rod.
Background technology
At present, piling machinery construction site using has two kinds：A kind of swivelling pile driver, the structure of this piling machine
It is the drilling rod hanger bracket using hoist engine pull-up, by driving rod bit to set to the piling of drifter drill for underground pore-forming by unit head
Standby；Another kind is jump bit piling machine, and the structure of this piling machine is repeatedly to be fallen using hoist engine pull-up jump bit, and lifting comes
Realize piling.Wherein, swivelling pile driver mainly circumferentially rotates, by drilling rod, the purpose to realize to underground drilling rod in piling,
Using being in the milk, drilling rod is lowered the temperature while drilling rod is holed and drilling rod is carried out with cementing operations, common grouting is main
Whitewashed by the grout hole of drill rod end, when drilling rod gets into certain depth, needed to drilling rod supernumerary segment, so that drilling rod is extended,
Drill down could be continued, during supernumerary segment, need shutdown operation, whitewash in stopping process and also stop, gunniting hole easily block and
Impact job schedule.
In order to solve the problems, such as prior art, people have carried out long-term exploration it is proposed that solution miscellaneous
Scheme.For example, Chinese patent literature discloses a kind of bored concrete pile screw lifting slurry-mud drilling rod [application number：
201410263015.7], it includes one section or some sections of hollow drills and coupled tool joint, outside hollow drill
Helical blade is provided with surface, is connected with tool joint between every section of hollow drill of every section of hollow drill, first segment hollow drill
Mouth spray is set with the junction of drill bit.Generally, this helical blade is welded on core drilling, and is arranged under hollow drill
Section, the length of helical blade is the 1/4-1/2 of the total length of hollow drill, and its diameter is less than the diameter of drill bit.Spiral shell in construction
Vane piece rotates with drilling rod positive direction, and clod in the mud to stake holes hypomere and mud etc. produces lifting force upwards, simultaneously
Downward propulsive force is produced to drilling rod.Such scheme to some extent solves asking of existing drill pipe for pile driver grouting effect difference
Topic, but the program still exists：Need to shut down and just enable extension arm.
The patent drill pipe for pile driver assembly [application number of application before the applicant：201610068750.1], including hollow
Drilling rod body, drilling rod body one end has drill bit tapering, and one end outer circumferential being provided with drill bit tapering in drilling rod body is provided with and is in
The augers blade of spiral distribution setting, augers blade one end extends to drill bit tapering, and the other end is set with radial direction
Put the whitewashing seat in the external side of drilling rod to be connected, whitewashing seat has at least one and portion in drilling rod body towards the side in drill bit tapering
Connected gunniting hole, and the aperture of gunniting hole becomes larger from inside to outside.Advantage is：It is not susceptible to blocking existing during whitewashing
As, and there is whitewashing area greatly, serosity can be made to be in fan-shaped ejection, gunite effect is good, good stability when drilling rod circumferentially rotates is difficult
Dancing occurs, improves the efficiency of drilling rod boring, be difficult between drilling rod to interfere.But program a fly in the ointment
It is that the length of drilling rod is unable to real-time adjustment.

Bar 11 inside and another adjusting rod 11 top adjacent with this adjusting rod 11.That is, the adjusting rod 11 of the present embodiment can
Setting 2 and more than, thus reaching longer flexible, for making the longer cement mixing method of length or drilled pile.
The operation principle of the present embodiment is：
Due to the adjusting rod 11 of some mutual sockets of inclusion of the present embodiment, boom running block 9 is arranged on outmost
On adjusting rod 11, outmost adjusting rod 11 down moves at first, and when outmost adjusting rod 11 down moves, puts away sports equipment dynamic
Assembly pulley 12 is also synchronous downward, because running block 12 steel wire rope of putting away sports equipment connects its internal adjacent adjusting rod 11, therefore exists
Put away sports equipment running block 12 down when, also pull adjacent adjusting rod 11 down to move simultaneously, the like, thus driving all of
Adjusting rod 11 is synchronous down to be extended, and then drives drive rod 3 down to extend, reaches the purpose adjusting run of steel.When putting away sports equipment,
Hoist engine 10 of putting away sports equipment works, and tightens up steel wire rope, and boom hoist engine 7 puts rope, during hoist engine 10 rope closing of putting away sports equipment, innermost adjusting rod
11 are up stretched first, drive main drilling rod 3 up, and pull neighbouring running block 12 of putting away sports equipment to rise, thus driving neighbouring
Adjusting rod 11 rise, neighbouring adjusting rod 11 drives another neighbouring running block 12 of putting away sports equipment to rise again, thus driving another
One adjusting rod 11 rises, the like.During drilling rod 100 rises and declines, can work always, can be using repeatedly
Rise and decline, realize the effect stirring, obtain high-quality cement-soil-stirred pile.
