The top part of the drilling rod body is provided with a grouting connector which comprises a grouting elbow pipe, a static internal pipe, a sealing piece, a rotary shell and a bearing, wherein the grouting elbow pipe and the static internal pipe are arranged together; a plurality of sets of bearings and a plurality of layers of sealing are arranged between the static internal pipe and the rotary shell; and the rotary shell and the seamless pipe body of the drilling rod body are arranged together. The sliding active drilling rod of the pile work drilling machine is a suspensible device capable of moving in an axial direction, transferring an axial force and a bidirectional torque upwards or downwards, receiving a drive and transmitting the drive to a drilling machine, which is used for driving a pile hole construction drilling machine and increasing drilling operation depth. Compared with the prior art, the sliding active drilling rod can increase the depth of a drilled hole and ensure construction safety and reliability on the basis of not increasing the height of a pile frame.
Description
(1) technical field
The present invention relates to a kind of drilling tool drive unit of piling machinery, the specifically a kind of drilling tool driving of piling machinery and sliding active drilling rod of the purposes of falling the bar of being applied to.
(2) background technology
The major function of piling machinery is exactly that drilling tool rotation or the static pressure that will design go into to form the stake hole in the stratum, at present, the depth of pore forming of piling machinery is lower than the height of pile frame mostly, existing drilling tool type of drive can't extend to hole depth at all and be higher than the pile frame height, therefore, along with the increase of stake hole projected depth, stake construction equipment pile frame is done higher and higher mostly, and working security and reliability all can not get ensureing.
(3) summary of the invention
Technical assignment of the present invention is at the deficiencies in the prior art, and providing a kind of can increase the sliding active drilling rod of pile work drilling machine of drilling depth under the prerequisite that does not increase the pile frame height.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of sliding active drilling rod of pile work drilling machine, comprise drilling rod body and the output joint that is positioned at drilling rod body bottom, the drilling rod body comprises body and vertically is arranged on two groups or more " worker " type driving key on the body, and " worker " type driving key is provided with alignment pin, is provided with filling adaptor at the top of drilling rod body.Driver part (as unit head) can be along the kelly axial slip, and can drive in any one group of " worker " type driving key position, can drive the pile hole construction drilling tool and increase the bore operation degree of depth by driving driving key.But but driving key is can hang axial slip bi-directional moment of torsion, can make progress or transmit axial force downwards, and accepts to drive and this driving is passed to the device of drilling tool.Based on above-mentioned characteristic, this kelly is a kind of device that reduces the tower mast height.
Above-mentioned drilling rod body is the critical piece of this drilling rod, driving key is divided into two groups up and down at least, every group of " worker " shape key that a plurality of symmetric arrangement are arranged, driver part can be along drilling rod body axial slip between last driving key and underdrive key, and can be on the drilling rod body driving key and two positions of underdrive key drive.When drilling depth than driver part stroke hour, just driver part can be finished drilling construction in feeding stroke, the underdrive key that driver part can be positioned at the drilling rod body so just can carry out full hole drilling; When drilling depth is bigger than driver part stroke, can be under the situation that does not increase the pile frame height, finish full hole drilling, specific implementation process is: the end from perforate to the driver part stroke,, driver part is positioned at the underdrive key position, when driver part arrives extreme lower position, stop to drive, driver part is reversed behind the certain angle, driver part is raised to the driving key position, use the slippage function to finish down bar, continue then to creep into to the hole depth requirement.When driver part during at the underdrive key position, owing to holding the drilling rod body high on the driver part, in rotation process, in driver part, come off in order to prevent the drilling rod body, design has special-purpose alignment pin on the drilling rod body, can prevent effectively that the drilling rod body from dropping.
Above-mentioned sliding active drilling rod of pile work drilling machine, its filling adaptor comprises slip casting bend pipe, static interior pipe, rotatable shell, bearing and seal, slip casting bend pipe and static interior pipe are set together, be provided with many cover bearings and multi-sealed in static between pipe and the rotatable shell, when drilling rod turns round slip casting sebific duct, slip casting bend pipe and static in pipe be not rotating with drilling rod, the slip casting sebific duct is wound on the drilling rod when so just having avoided the drilling rod revolution.The seamless tube body of rotatable shell and drilling rod body is set together, and can together rotate with the drilling rod body.
Above-mentioned sliding active drilling rod of pile work drilling machine, its slip casting bend pipe is used to change the angle that the slip casting sebific duct inserts filling adaptor, the slip casting bend pipe is generally the semicircle bend pipe of 180 degree, and the slip casting sebific duct can directly insert from the below like this, has effectively avoided the crooked access of slip casting sebific duct.
Between above-mentioned static interior pipe and the rotatable shell quadruplet ball bearing is housed, bearing inner race is enclosed within on the static interior pipe, and the lower end is fixed by two round nuts, and bearing outer ring and rotatable shell are fixed, and form rotatable filling adaptor.
Above-mentioned sliding active drilling rod of pile work drilling machine, its joint is six square joints, utilizes this six square joint to fuse with other drilling rods.
In this kelly grouting pipe is arranged, the slip casting bend pipe on grouting pipe and the drilling rod body forms put-through channel, plugging in the time of can effectively preventing slip casting.
A kind of sliding active drilling rod of pile work drilling machine of the present invention compared with prior art, the beneficial effect that is produced is, reasonable in design, simple in structure, driver part can be along the slippage of drilling rod body, and can drive at driving key position arbitrarily, on the basis that does not increase the pile frame height, increase drilling depth, ensured working security and reliability.
