Abstract
The utility model discloses a broken rock drill's of going into of hydraulic rotary drill down-the-hole device that splines relates to a broken rock drill's of going into of down-the-hole mode that splines that is applicable to the full-hydraulic rotary drill of power head formula and goes into rock drilling. The anti-slip device mainly solves the problem that the existing anti-slip device is likely to slip in the construction process because the rotary joint prevents the rotation of the shell by utilizing the extrusion of the roller of the shell and the rock wall, and if part of rock is under soft soil, the rotary joint is directly utilized to stop the rotation. The utility model discloses an install an oil circuit rotary joint subassembly additional in the upper end of rotary drill drilling machine drilling rod, the dabber lower extreme and the drilling rod of rotary joint subassembly are connected, and the upper end and the elevator of rotary joint subassembly dabber are connected, and the shell of rotary joint subassembly is connected on the walking frame, and the walking frame is installed on rotary drill's mast. When part of rock positions are under the soft soil, the utility model can stop rotating by utilizing the rotary joint without slipping; simple structure, low cost and high working efficiency.
Description
Technical Field
The utility model relates to a full-hydraulic rotary drill of power head formula specifically relates to a broken mode of splining of rock drill of going into of down-the-hole suitable for full-hydraulic rotary drill of power head formula goes into rock drilling.
Background
The patent No. 201420837428.7's utility model discloses a dig broken rock drill of stake machine hole bottom hydraulic pressure high frequency down-the-hole soon, this dig broken rock drill of stake machine hole bottom hydraulic pressure high frequency soon prevents its shell rotation because rotary joint utilizes the gyro wheel and the rock wall extrusion of its shell (5A 1) in the construction, consequently, there is following problem, when meetting the rock wall loose, big hour when easily causing the extrusion force of gyro wheel and rock wall little, if when some rock position is below the weak soil, directly utilize rotary joint to spline, the phenomenon of skidding probably appears, install down the words of protecting a section of thick bamboo additional, increase the process, and high cost reduces the efficiency of construction.
Disclosure of Invention
The utility model aims at foretell not enough and the one that provides need not increase the process, simple structure, it is with low costs, the work rate is high, if have partial rock position when below the weak soil, directly utilize rotary joint to splines, the hydraulic pressure rotary drill down-the-hole breakage that the phenomenon of skidding can not appear is gone into the rock drill and is only changeed the device.
The technical solution of the utility model is that: the upper end of a drill rod of the rotary drilling machine is additionally provided with an oil way rotary joint assembly, the lower end of a mandrel of the rotary joint assembly is connected with the drill rod, the upper end of the mandrel of the rotary joint assembly is connected with an elevator, a shell of the rotary joint assembly is connected to a traveling frame, and the traveling frame is installed on a mast of the rotary drilling machine.
The technical solution of the utility model in the shell of rotary joint subassembly connect on establishing the outside oil pipe in the retinue frame below, the dabber of rotary joint subassembly with pass the inside oil pipe on the drilling rod hole and be connected, the one end that inside oil pipe wore out the drilling rod hole is connected on the vibrator.
The utility model discloses a connect the shell of rotary joint subassembly below the follower frame, utilize the follower frame to come the spline, elevator and drilling rod and vibrator drill bit are connected respectively to the dabber of rotary joint subassembly, accomplish the rock drilling. The shell of the rotary joint component is connected with an external oil pipe, and the core of the rotary joint component and the internal oil pipe of the vibrator are buried in the drill rod. The accident of the oil pipe and the hole wall or other objects in the hole is avoided; when partial rock positions are under the soft soil, the rotation stopping is carried out by utilizing the rotary joint, and the phenomenon of skidding cannot occur. The utility model discloses need not increase the process, simple structure, it is with low costs, work efficiency is high.

Detailed Description
As shown in fig. 1 and 2, the utility model discloses an install an oil circuit rotary joint subassembly 5 additional at the upper end of rotary drill 1 drilling rod 6 and the lower extreme of rotary drill 1 elevator 4 that the rotary drill down-the-hole breakage goes into the rock drill, the lower extreme of oil circuit rotary joint subassembly 5 passes through the flange and is connected with drilling rod 6, the dabber 5A2 upper end and the elevator 4 of oil circuit rotary joint subassembly 5 are through the pin junction of elevator 4 self-carrying, the shell 5A1 of oil circuit rotary joint subassembly 5 is connected at the lower extreme of rotary drill 1 pallet 3, be fixed with a mast on rotary drill 1, pallet 3 installs on this mast; the lower end of the drill rod 6 passes through the rotary power head 2 and is connected with a vibrator 8 and a drill bit 9; the shell 5A1 of the oil path rotary joint component 5 is connected to an external oil pipe 10, and the external oil pipe 10 is arranged at the lower end of the traveling frame 3; the mandrel 5A2 of the oil path rotary joint component 5 is connected with the internal oil pipe 7 through a joint of the oil pipe, the internal oil pipe 7 passes through the inner hole of the drill rod 6, and one end of the internal oil pipe 7 passing through the inner hole of the drill rod 6 is connected with the vibrator 8; oil circuit rotary joint subassembly 5 is by the rotary joint overcoat with establish the center pin in the rotary joint overcoat to and rotary joint dabber 5A2 constitutes, concrete structure is the same with the structure that patent number is 201420837428.7, rotary joint dabber 5A2 is established in the rotary joint overcoat, adopt the bearing to be connected between rotary joint dabber 5A2 and the rotary joint overcoat, rotary joint dabber 5A2 overlaps on the center pin, adopt damping rubber to be connected between rotary joint dabber 5A2 and the center pin.
The working principle is as follows: when the rotary drilling machine works, the power head of the rotary drilling machine 1 drives the drill rod 6 to rotate, the drill rod 6, the vibrator 8 and the drill bit 9 rotate together, and meanwhile, the main steel wire rope of the rotary drilling machine 1 drives the elevator 4, the rotary joint assembly 5, the traveling frame 3, the drill rod 6, the vibrator 8 and the drill bit 9 to move downwards together to start drilling work. The follower 3 and the housing 5a1 of the swivel joint assembly 5 slide up and down along the mast of the rotary drilling rig 1 without rotating; when the drilling is stopped, the main steel wire rope of the rotary drilling machine 1 drives the elevator 4, the rotary joint component 5, the follower 3, the drill rod 6, the vibrator 8 and the drill bit 9 to ascend together, the drill rod 6 can continue to rotate or stop rotating, and the ascending and the rotating are stopped after the drill rod is lifted in place. One duty cycle is completed.
