Specific implementation mode
The implementation of the utility model is described as follows below in conjunction with the accompanying drawings：
As shown in Figs. 1-5, a kind of drilling machine power head switching mechanism, which is characterized in that including
Overturning oil cylinder 1, installation planker 2, power head 3, drilling rod 17 and advance frame 15；
The installation planker 2 is made of the bottom plate 2.2 of two side plates 2.1, and two lateral plate structures are identical, the bottom plate connection
Between even side plate, the bottom plate is centrally disposed, and there are two mounting holes 2.3, are fixedly connected with outer end by mounting hole；
It is provided with the first pin hole 14 at the top of the side plate, the first axis pin 4 is set in the first pin hole, is arranged on axis pin and turns over
Turn oil cylinder 1, passes through the first axis pin connecting lateral plate and overturning oil cylinder；The piston rod of overturning oil cylinder with power head by being connected；
The tail portion of power head is provided with the second pin hole 16, and second axis pin 6 is arranged in the second pin hole 16, the overturning
The piston rod of oil cylinder is rotatablely connected by the second axis pin and power head 3；
The left side of side plate 2.1 is provided with mounting plate, opens up mounting hole on the mounting plate, on the power head, position
It is provided in the second pin hole lower end and is connected by the way that connector is arranged with mounting hole with 13 matched pilot hole of mounting hole, the pilot hole
Connect power head and side plate；
The connector includes fixed pin 10 and fixing sleeve 11, and the fixing sleeve 11 is set in outside fixed pin, fixed pin
10 are fixed by hex bolts 8, and fixing sleeve 11 is fixed by hexagon socket head cap screw 9；
A link mechanism is formed between overturning oil cylinder 1 and power head 3, is stretched out by 1 piston rod of overturning oil cylinder, and power is driven
First 3 are flipped up, and piston rod is withdrawn, and power head 3, which is driven, to be downwardly turned over.
Further improvement of these options, two side plates and the welded molding of bottom plate.
The tail end of further improvement of these options, the second axis pin 6 is provided with shaft retaining ring 7.
On the first axis pin, split pin 5 is provided with perpendicular to the axis direction of axis pin for further improvement of these options.
The mounting means of power head is radial type structure, and the overturning oil cylinder being mounted on planker connects with power head holder in one
Linkage, traction power head circumference is dynamic around mounting pin shaft rotation when cylinder piston rod is stretched out and bounced back, and turn over function is realized with this；Oil cylinder
Flexible stroke under the action of hydraulic pressure locking-valve, stop can be stablized at an arbitrary position, therefore the flip angle of power head can set
It counts arbitrarily to stablize in range and stop.
When the power head of drilling machine drops to advance frame low level, manipulating overturning oil cylinder 1 makes piston rod stretch out, and power head 3 will
It is flipped up therewith, close to horizontality, drilling rod 17 can be lifted from piling bin 15 and be docked to power head by operating personnel at this time
Out splice going splice, start drill power head rotation, drilling rod can be screwed on；When power head rises to a high position for advance frame, manipulation is turned over
Turning oil cylinder 1 makes piston rod retract, and drilling rod just in vertical state, can carry out drilling operation at this time.
Such as the above process, for reversible power head in vertical construction, power head is down toward low level, and output end variable angle is at connecing
Nearly horizontality enables adjunction long drill pipe easily to realize, greatly improves work efficiency；It needs to dismount in power head and safeguard
When, it can also multidirectional operation.
It should be noted last that the above specific implementation mode is only to illustrate the technical solution of the utility model rather than limit
System, although the utility model is described in detail with reference to example, it will be understood by those of ordinary skill in the art that, it can be right
