Circumferential installation screw is arranged in the lower end lower mounting seat 7-17, for installing lower platen 7-20, in order to buffer drilling tool in work
Lower yielding rubber pad 7-21 is arranged in vibration when making between lower mounting seat 7-17 and lower platen 7-20.
The course of work of the invention is as follows:
The position that crawler body 1 drives drilling-machine shifter to drill to needs, turntable 3 drive rack 8 to turn to suitable angle, supporting leg
9 decline rear support racks 8 keep stablizing, and advance frame 5 is pushed into vertically by balladeur train 4, and clamper 10 installs drilling tool to damping core pipe 7
Lower end, drilling tool under the driving of power head, by core pipe drive realize revolution movement, under the propulsion of advance frame 5 realize feed
Movement, further realizes drilling construction.
The butter duct 5-6-2 in butter cylinder body 5-6 is injected from oiling check valve 5-15 by butter, in the closing of check valve
Under effect, butter pushes piston rod 5-7 to push tensioning wheel frame body 5-9 outward, realizes driven sprocket 5-10 by roller chain 5-8
Tensioning.
The drive motor 5-4 of top two sides drives speed reducer to provide driving force, and drive sprocket rotation is further driven to roller
Chain 5-8 is mobile.
It is rotated under the drive of roller chain 5-8 with movable sprocket 5-13, encoder 5-14 is converted to the return data of sprocket wheel
The linear motion signal of chain, is further transferred to host service function interface.
Power head drive motor 6-6 drives Large Gear Shaft 6-2 to make revolution fortune by motor connecting shaft 6-4 and gear structure
It is dynamic, to meet compact dimensions, propulsion stroke space is conceded, this power head uses slim cabinet, the installation of motor unilateral side, large transmission ratio
Mode realize；Power head need to be added by pinion end with forced lubricating pump, and the operating condition of high load capacity lower tooth wheel system is improved；
Match rotating speed coder in synchronous increase of another pinion-end simultaneously, tach signal is exported to main engine control panel.
7 mesohigh core pipe channel of damping core pipe, interior airway passage, the working implementations in exterior air drain channel are as follows: drilling machine
When drilling down, power head 6 drives drilling tool strength to turn round, and advance frame 5 generates down thrust, and big flow is compressed in exterior air drain channel
Air is input to bottom hole pneumatic down-hole hammer, and driving down-hole hammer makees percussion action, smashes the difficult drilling formations such as the block stone in stratum, and
Rubble residue is blown off bottom hole, the resilient cushion up and down of core pipe plays the role of absorbing vibration at this time, protects core pipe and drilling tool；Drilling machine
When up proposing drilling row whirl spraying operation, high pressure water mud is by high pressure core pipe channel, until forming secondary add at the nozzle of drill bit
Pressure makees high-pressure jet shape cutting soil, the small flow constriction air of interior airway passage, by interior airway passage, until slurries spray
The outer ring of mouth forms gas bag negative pressure, increases the concentration degree of jet stream at nozzle, makes the energy elongated segment of jet stream, enhancing soil body cutting
Mixing effect further enhances pile-forming effect.
