Description
Technical field
The utility model relates to engineering machinery fields, and in particular to a kind of power head control system and drilling machine.
Background technique
When horizontal directional drilling machine is constructed, the operation that power head is rotated and moved linearly simultaneously on drilling cramp, mobile
Direction includes forwardly and rearwardly.The spinning movement of power head and linearly operating are controlled by individual handle, and spinning movement is by revolving
Handle control is changed hands, linearly operating is controlled by drawing handle.Specifically, the rotation speed of left-handed and dextrorotation by be pushed forward or after
Automatically controlled rotating handle is drawn to realize.Rotating handle is pushed forward or post-tensioning angle is bigger, and the speed of power head left or right rotation is faster.Dextrorotation
It is working condition, left-handed is disassembly status.That is, power head is just left-handed, left-handed to can be achieved to unload only in dismounting drilling rod
Button.The movement that moves forward and backward of power head is by being pushed forward or the automatically controlled drawing handle of post-tensioning is realized.Electric control handle is pushed forward or post-tensioning angle
Degree is bigger, and the speed that power head is run forward or backward is faster.
Inventors have found that at least there are following problems in the prior art: the distance constructed by medium-and-large-sized directional drilling machine
Longer (typically larger than 0.5Km), and pipeline is relatively thick (general diameter is greater than 0.7m).Drilling machine needs first in each construction with brill
Head makes the pilot hole of corresponding construction distance in underground；Then according to the needs of construction geology, selection from small to large, different-diameter
It returns and expands head time expansion pilot hole.Due to extending in last time trombone slide line process in each return, power rotates side in front and moves forwards,
Often retract a run of steel will dismounting drilling rod, at this moment power head will stop dextrorotation and retrogressing.But due to returning the distance expanded
Or the distance of last time trombone slide line is longer, although rotation and drawing handle returned to middle position, due to rotation reactive torque and
Return the reaction pulling force of enlarging aiguille or pipeline, power head just rotates to the left and move forwards trend, such rotation motor and pushes away
Draw motor inverted running in motorless situation.Since power oil-duct has been turned off, cause rotation motor and push-and-pull motor because of oil
Road is emptied damage, this not can guarantee the construction speed and safety of directional drilling machine not only, while bring great economy to user yet
Loss.

Another embodiment of the utility model provides a kind of drilling machine, including moves provided by any technical solution of the utility model
Power head control system.
The course of work of drilling machine is as follows:
When horizontal directional drilling machine is constructed, power head is run forward or backward on drilling cramp top rotation side, left or right rotation
Speed by automatically controlled rotation control handle 42 be pushed forward or post-tensioning realize.Rotation control handle 42 is pushed forward or post-tensioning angle is bigger, moves
The speed of power head left or right rotation is faster.Only in dismounting drilling rod, power head is just left-handed.The operation of power head forward or backward
By automatically controlled push-and-pull control handle 41 be pushed forward or post-tensioning realize, electric control handle is pushed forward or post-tensioning angle is bigger, power head forward or to
The speed run afterwards is faster.
Hold above-mentioned, in actual work, since stratum is varied, when stratum is softer, the dextrorotation speed of power head is slow
It is some, and pushing ahead or return the speed dragged backward will fastly, when stratum is harder, the dextrorotation speed of power head wants fast one
A bit, it pushes ahead or to return the speed dragged backward slow, and power head is when changing drilling rod, it is unloaded from drilling cramp rear end to drilling cramp
Front end operation, in order to save the construction time, power head can be moved forwards at a high speed, be obtained by power head rotation motor or push-and-pull motor
The quantity of electricity may be implemented the dextrorotation of power head high speed, advance at utmost speed or high reverse.
Relatively thick (the general diameter of the distance longer (typically larger than 0.5KM) and pipeline constructed by medium-and-large-sized directional drilling machine
Greater than 0.7m), drilling machine needs first to make the pilot hole of corresponding construction distance in underground with drill bit in each construction；Then basis
Construction geology need, selection from small to large, different-diameter return expand head return expansion pilot hole.Due to extending to last time in each return
During trombone slide line, power rotates side in front and moves forwards, often retract a run of steel will dismounting drilling rod, at this moment power
Head will stop dextrorotation and retrogressing.But it is anti-due to rotation since the distance for returning the distance or last time trombone slide line that expand is longer
Trend is just rotated to the left and moves forwards to torque and time counterboring bar or pipeline reaction pulling force, power head.Especially drilling rod
Left-handed rotation, may cause the tripping of drilling rod and be embedded in underground.
No matter power head high speed low speed rotation or front and back operation, as long as controller 6 detect rotation control handle 42, push away
When 152 ends or 140 ends for drawing control handle 41 are close to 0V, 131 ends or 141 ends of controller 6 just export electric signal, the first electromagnetism
32 energized action of valve 31 or second solenoid valve, the first rotation motor 141, the second rotation motor 143, first push-and-pull motor 131, the
The brake of two push-and-pull motors 133, third push-and-pull motor 135 and the 4th push-and-pull motor 137 is in closed state, and power head is vertical
Stop rotating left and right, move forward or back, prevents power head rotation motor or push-and-pull motor due to power source is out of service anti-
To rotation, cause pipeline to be emptied and damage motor, to guarantee the safe construction of directional drilling machine, reaches energy-saving and environment-friendly purpose.
