Abstract
A power head drill rod locking mechanism comprises a power head, wherein locking cylinders are arranged at the upper end and lower end of the power head respectively, a horizontal main shaft is arranged in the middle of the power head and is sleeved with a locking sleeve, vertical pressing plates are arranged on the two sides of the main shaft respectively, one end of each pressing plate is installed on a piston rod of the corresponding locking cylinder and fixedly connected with the piston rod of the locking cylinder, the other end of each pressing plate is installed on the main shaft and movably connected with the main shaft, a bearing hole is formed in the position where each pressing plate is connected with the main shaft, and a bearing is arranged in each bearing hole. By the adoption of the mechanism, manual intervention is not needed during automatic screw off of a drilling machine, time and labor are saved, and using is convenient.
Description
Technical field
The present invention relates to a kind of unit head drilling rod retaining mechanism.
Background technology
The existing rig with automatic connecting and disconnecting drill rod function, when automatic connecting and disconnecting drill rod, because drill-rod screw processing quality is unstable or drilling rod thread abrasion after use, being threaded between main shaft and drilling rod surprisingly may be unclamped when unloading drilling rod, often need manual intervention, rig can not realize Automated shackle.At present, a kind of mechanism being specifically designed to locking drilling rod is not also had.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency of above-mentioned background technology, provides a kind of rig Automated shackle process without the need to manual intervention, time saving and energy saving, unit head drilling rod retaining mechanism easy to use.
The technical scheme that the present invention solves the employing of its technical problem is, a kind of unit head drilling rod retaining mechanism, comprise unit head, the top and bottom of described unit head are respectively provided with locking cylinder, the main shaft of level is provided with in the middle part of unit head, on described main shaft, cover has lock sleeve, the both sides of main shaft are respectively provided with vertical pressing plate, described pressing plate one end is arranged on the piston rod of locking cylinder, be fixedly connected with the piston rod of locking cylinder, the other end of pressing plate is arranged on main shaft, is connected with spindle mobility, the junction of pressing plate and main shaft is provided with dead eye, is provided with bearing in described dead eye.
Further, the surface of described main shaft is provided with flat key.
Further, described dead eye is provided with bearing cap.
Further, described pressing plate one end is arranged on the piston rod of locking cylinder by nut.
Compared with prior art, advantage of the present invention is as follows:
Be provided with locking cylinder, pressing plate, lock sleeve, the piston rod of locking cylinder stretches out, and the pressing plate promoted on piston rod moves, and pressing plate promotes lock sleeve relative main and slides, compress the drilling rod end face be connected with spindle thread, increase thread friction power, prevent unexpected the releasing that be threaded between main shaft and drilling rod, reach the object of locking drill rod thread, enable rig Automated shackle, without the need to manual intervention, time saving and energy saving, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the sectional view of Fig. 1 along A-A.
In figure: 1-unit head, 2-locking cylinder, 3-pressing plate, 4-bearing, 5-bearing cap, 6-lock sleeve, 7-flat key, 8-main shaft.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, Fig. 2, the present embodiment comprises unit head 1, the top and bottom of unit head 1 are respectively provided with locking cylinder 2, the main shaft 8 of level is provided with in the middle part of unit head 1, the surface of main shaft 8 is provided with flat key 7, on main shaft 8, cover has lock sleeve 6, the both sides of main shaft 8 are respectively provided with vertical pressing plate 3, pressing plate 3 one end is arranged on by nut on the piston rod of locking cylinder 2, be fixedly connected with the piston rod of locking cylinder 2, the other end of pressing plate 3 is arranged on main shaft 8, be flexibly connected with main shaft 8, pressing plate 3 is provided with dead eye with the junction of main shaft 8, bearing 4 is provided with in dead eye, dead eye is provided with bearing cap 5.
During use, drilling rod and main shaft 8 end are threaded connection, locking cylinder 2 leads to pressure oil, the piston rod of locking cylinder 2 stretches out, the pressing plate 3 promoted on piston rod moves, and pressing plate 3 promotes lock sleeve 6 relative main 8 and slides, and compresses the drilling rod end face be threaded with main shaft 8, increase thread friction power, reach the object of locking drilling rod.
The present invention is on the basis analysed in depth main shaft 8 and the principle that is threaded between drilling rod, thread friction resistance is increased by the normal pressure increased between main shaft 8 and drilling rod between screw connection structure end face, and make this frictional resistance be greater than power needed for rig Automated shackle, prevent unexpected the releasing that be threaded between main shaft 8 and drilling rod, reach the object of locking drill rod thread, enable rig Automated shackle.
Those skilled in the art can carry out various modifications and variations to the embodiment of the present invention, if these amendments and modification are within the scope of the claims in the present invention and equivalent technologies thereof, then these revise and modification also within protection scope of the present invention.
The prior art that the content do not described in detail in description is known to the skilled person.
