Abstract
The invention discloses the brake apparatus of swivel joint hollow in stake holes, which is mounted on the arrestment mechanism of the hydraulic oil pipe rotation in hollow swivel joint for preventing in stake holes；Ground drill power head is connected on transmission shaft, under be connected to hydraulic hole drilling hammer or pneumatic down-hole hammer, torque is transmitted to hydraulic hole drilling hammer or pneumatic down-hole hammer；Brake links together with hollow swivel joint, while the branch wall stand in brake is stretched out, and is supported on stake holes inner wall.In drilling tool rotation, the hollow swivel joint outer ring rotating of connection hydraulic oil pipe is prevented, hydraulic oil oil pipe is made not wind drilling tool, hydraulic hole drilling hammer or pneumatic down-hole hammer drilling tool can be crept into a direction continuous rotation.The configuration of the present invention is simple, it is easy to operate, when solving drilling drilling tool in one direction continuous rotation when, the external functional fluid pressure line of drilling tool or gas circuit do not wind the directionality problem of drilling tool in hole.
Description
Technical field
The invention belongs to pile foundation engineering drilling tools, are specifically related to a kind of novel mode of braking of hydraulic pipeline.
Background technique
In the prior art, carry out lithosphere pile foundation construction in, carry out lithosphere piling construction it is extremely difficult, it is existing at first
Into be using pneumatic down-hole hammer and hydraulic hole drilling hammer in lithosphere piling technology, and both large-scale pile foundation down-hole hammers are using
Hydraulic oil pipe or tracheae are external on drilling tool in the process；When construction, the prior art not can solve hydraulic oil pipe or tracheae in drilling tool
When rotation hydraulic oil pipe or tracheae winding drilling tool the problem of, cause drilling tool that can only rotate left and right in boring procedure and cannot be continuous
Rotation, so that drilling quality (borehole perpendicularity is bad) is influenced, while hydraulic oil pipe or tracheae service life are short, frangibility, accidentally
Work is mistaken.
Patent 201610455736.7 discloses the broken rock device on a kind of rotary pile-digging machine.It mainly solves rotary pile-digging machine
Hydraulic shock when piercing rock can not one-step pore-creating, wear the slow-footed problem of rock.External extension brill is cased on the outside of interior telescopic drill rod
The upper end of bar, the swivel joint that broken rock is bored is connected to the lower end of interior telescopic drill rod, and the lower end of swivel joint is connected in slide cartridge
On cushion socket, the upper end of slide cartridge is connected on external extension drilling rod, and the lower end of slide cartridge is connect by adapter flange with elevator seat, is mentioned
The upper and lower side of lead device seat is connect with elevator and vibration hammer respectively, and the other end of elevator is connected to the steel of drilling machine by wirerope
On cord twisted seat.
Patent 201410271719.9, which discloses one kind, can bore oil in the down-the-hole broken rock that rotary drilling rig foot of hole uses
Pipe swivel joint rotation stop device.It mainly solves known rotary drilling rig in the construction process, and oil pipe swivel joint is in bottom hole
Can not effective rotation stop, not can avoid oil pipe and wound on drilling rod, thus cannot achieve by power source be transported to foot of hole carry out
The problem of operation.The present invention is equipped with rotation stop casing in the outside of swivel joint, and rotation stop casing is connected to back by slideway thereon
On bolt on adapter, claw is installed on rotation stop casing.Mainly using rotation stop casing by claw and hole wall friction come
Reach rotation stop effect, oil pipe is avoided to wind on drilling rod, power source is delivered directly to foot of hole and is used to support down-the-hole by realization
Broken rock bores operation.
Unlike the prior art, the present invention is quasi- will solve the problems, such as that this technological difficulties are as follows:
1. to guarantee construction torque bottom hole equipment is sent to from ground drill power head torque, and conveying high-pressure
Working media pipeline cannot wind drilling tool.
2. working media is transmitted to bottom hole equipment by hollow swivel joint by the prior art, it is related to hollow revolution
Connector stop problem.Hollow swivel joint stop cannot destroy hole wall, prevent collapse hole burying.Because collapsing in real traditional construction
Hole burying happens occasionally, and salvaging is almost impossible, cannot increase collapse hole probability because of chocking construction.
3. working media pipeline is also required to decline when equipment is constructed and crept into, oil pipe cannot be broken.
4. a pair working media pipeline is protected, the pollution environment such as leakage and oil product are prevented.
Summary of the invention
A kind of the present invention provides structures working media pipeline brake apparatus convenient, easy to operate, can greatly increase
The service life of pipeline guarantees drilling quality.New construction thinking is also increased in pile driving construction simultaneously.

Dynamic device includes brake, transmission shaft and hollow swivel joint；Transmission shaft top connects transition connecting rod, and transition connecting rod passes through
Drilling rod is connected on ground drill power head；Lower part is connected to oil catcher, and oil catcher is fixed on hydraulic hole drilling hammer or aeratic hidden hole
Torque, is transmitted to hydraulic hole drilling hammer or pneumatic down-hole hammer by hammer；
Brake is made of branch wall stand, opening and closing oil cylinder, crossbeam, rack fixing seat, flexible 2 arms and flexible 1 arm；Branch wall stand with
Lower bearing pin connects into parallelogram sturcutre on crossbeam, is driven by opening and closing oil cylinder.Crossbeam and opening and closing oil cylinder pin shaft are fixed on branch
In frame fixing seat.Rack fixing seat, flexible 2 arms and flexible 1 arm use square tube grafting or keyway grafting, guarantee that bracket is fixed
Seat, flexible 2 arms and flexible 1 arm are relatively unrotatable while sliding relatively.
Flexible 1 arm is fixed on hollow swivel joint outer ring, and hollow swivel joint inner ring is fixed on transmission shaft, works as liquid
Transmission shaft decline is driven when pressing down-hole hammer construction drilling, and then drives flexible 1 arm decline,；And the branch wall stand support on brake
Firmly stake holes inner wall remains stationary, because branch wall stand is fixed on rack fixing seat by crossbeam, so rack fixing seat is motionless, in this way
When the decline of flexible 1 arm, flexible 2 arms form relative telescopic sliding also with decline, simultaneously as rack fixing seat, flexible
2 arms and flexible 1 arm use square tube grafting or keyway grafting, 3 can only opposite sliding but relatively unrotatable, so revolution connects
Head outer ring (31) does not rotate；And it is fixed on the hollow swivel joint inner ring on transmission shaft and is rotated under the drive of drilling rod.In in this way
Backlash adapter outer ring does not rotate, and transmission shaft drives hollow swivel joint inner ring rotation, to be fixed on outside hollow swivel joint
External hydraulic oil pipe does not rotate without winding drill stem because of hollow swivel joint outer ring on circle；
Branch wall stand on brake is supported on stake holes inner wall and remains stationary, and provides identical tension by opening and closing oil cylinder and keeps branch wall stand
Clench stake holes inner wall.During construction drill, since this supporting point is motionless, only rack fixing seat, flexible 2 arms and stretch
1 arm that contracts is opposite to slide decline, can guarantee that stake holes inner wall does not damage well, while this structure is in limited stake holes, length with
Diameter is all very suitable to, and reduces the weight of entire drill bit and the damage of oil pipe.
