Description
Technical field
The utility model belongs to pile foundation engineering drilling tools, is specifically related to a kind of novel braking side of hydraulic pipeline
Formula.
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 utility model is equipped with rotation stop casing in the outside of swivel joint, and rotation stop casing is connected by slideway thereon
On bolt in swivel joint, claw is installed on rotation stop casing.Mainly rubbed using rotation stop casing by claw and hole wall
