Abstract
The utility model provides a power head connecting device of providing a two-way large torque aiming at the problems of an overlarge torque of the power head damages the thread of a connecting pipe and the floating shaft is easy to fall off while reversing. The power head connecting device of providing the two-way large torque includes a centre shaft and a floating shaft of the power head. The centre shaft of the power head is in a hollow mode, an inner thread is arranged at the lower end of the centre shaft of the power head, an outer thread is arranged at the upper end of the floating shaft, and the inner thread is connected with the outer thread in a screwing mode. The power head connecting device of providing the two-way large torque is characterized in that detachable flanges are arranged on the outer portion of the centre shaft and the floating shaft of the power head, a certain number of pin holes are arranged between the flanges, the flanges are connected mutually through the pin holes and bolts. The power head connecting device of providing the two-way large torque adds the flanges on the centre shaft and the floating shaft so as to improve the transmitted torque between the centre shaft and the floating shaft, prolong the service life of the device, reduce the maintenance cost and expenditure, and meanwhile avoid the fall-off of the floating shaft while reversing and production failure, improve the stability of device, and to improve the production efficiency and economic benefits.
Description
Technical field
The utility model relates to the engineering driller field, is specifically related to a kind of unit head linkage that two-way high pulling torque is provided.
Background technology
Rig is in geological prospecting, drives drilling tool and creeps into to underground, obtains the plant equipment of geologic information in kind, claims again rig.The Main Function of rig is to drive the broken hole of drilling tool bed rock stone, is lowered to or proposes the drilling tool in the hole.Can be used for drilling through rock core, the ore deposit heart, landwaste, gaseous state sample, liquid sample etc., to verify the situations such as subsurface geology and mineral resources.This rig is mainly used in well workover, the GEOTHERMAL WATER well construction of probing, oil well of coal-bed gas exploitation, shallow oil, natural gas and needs are crept in the exploration of satisfying domestic superdeep holes, also can be used for the construction of emergency dealing, mine ventilation hole, drainage pipe.
In the prior art, the unit head axis of rig is fixedly connected with by gas thread with floating axle, gas thread can be more and more tighter in the process of lower brill, if moment of torsion too conference damages gas thread, cause job failure, or meeting with bit freezing or mine middle the need in the process that counter-rotating promotes of speedily carrying out rescue work, the gas thread counter-rotating is unclamped, and causes floating axle to come off.
The utility model content
Floating axle this problem that easily comes off proposed a kind of unit head linkage that two-way high pulling torque is provided when the utility model existed gas thread that the excessive damage of unit head moment of torsion connects and counter-rotating for prior art.
The technical solution of the utility model is: a kind of unit head linkage that two-way high pulling torque is provided, comprise unit head axis and floating axle, the unit head axis is a hollow shaft, lower end at the unit head axis is provided with internal thread, the upper end of floating axle is provided with external screw thread, and internal thread is connected connection with external screw thread, in the outside of unit head axis and floating axle dismountable flange is housed, flange is provided with the pin-and-hole of some, connects by pin or bolt between the flange.
The described unit head linkage that two-way high pulling torque is provided, flange is installed on unit head axis and the floating axle by connecting key, and described connecting key is rectangular spline, involute spline, flat key or woodruff key.
The described unit head linkage that two-way high pulling torque is provided, the quantity of pin-and-hole is 3～10 on the described flange.
The beneficial effects of the utility model are: the utility model is fixedly connected on flange on unit head axis and the floating axle by the key connection, this connected mode, and enforcement simple in structure is convenient, and the mode that adopts key to connect makes things convenient for the installation and removal of flange; Set up flange at unit head axis and floating axle, improved the moment of torsion that transmits between the two, prolonged the application life of equipment, reduced maintenance cost, reduced expenditure, floating axle comes off when also having avoided counter-rotating simultaneously, causes fault in production, improve the stability of equipment, improved production efficiency and economic benefit.
