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, in automatic connecting and disconnecting drill rod, because of drill-rod screw processing quality
Unstable or drilling rod thread abrasion after use, the threaded connection between main shaft and drilling rod may be unexpected loose when drilling rod is unloaded
Open, generally require manual intervention, rig can not realize Automated shackle.At present, also without a kind of machine dedicated for locking drilling rod
Structure.
The content of the invention
The technical problems to be solved by the invention are to overcome the shortcomings of above-mentioned background technology, there is provided a kind of rig is unloaded automatically
Cheng Wuxu manual interventions are snapped through, time saving and energy saving, easy to use unit head drilling rod retaining mechanism.
The present invention solves the technical scheme that its technical problem uses, a kind of unit head drilling rod retaining mechanism, including power
Head, the top and bottom of the unit head are respectively provided with locking cylinder, and unit head middle part is provided with horizontal main shaft, is covered on the main shaft
The both sides for having lock sleeve, main shaft are respectively provided with vertical pressing plate, and described pressing plate one end is arranged on the piston rod of locking cylinder, with lock
The piston rod of locking oil cylinder is fixedly connected, and the other end of pressing plate is arranged on main shaft, is connected with spindle mobility, the company of pressing plate and main shaft
The place of connecing is provided with bearing hole, and bearing is provided with the bearing hole.
Further, the surface of the main shaft is provided with flat key.
Further, the bearing hole 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, advantages of the present invention is as follows：
Locking cylinder, pressing plate, lock sleeve are provided with, the piston rod of locking cylinder stretches out, promote the pressing plate movement on piston rod,
Pressing plate promotes lock sleeve relative main to slide, and the drilling rod end face that compression is connected with spindle thread increases thread friction power, prevents master
Threaded connection between axle and drilling rod is surprisingly released, and reaches the purpose of locking drill rod thread, enables rig Automated shackle, without people
Work is intervened, time saving and energy saving, easy to use.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is sectional views of the 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.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
Reference picture 1, Fig. 2, the present embodiment includes unit head 1, and the top and bottom of unit head 1 are respectively provided with locking cylinder 2, moves
First 1 middle part of power is provided with horizontal main shaft 8, and the surface of main shaft 8 is provided with flat key 7, lock sleeve 6, the both sides of main shaft 8 are cased with main shaft 8
Vertical pressing plate 3 is respectively provided with, the one end of pressing plate 3 is arranged on the piston rod of locking cylinder 2 by nut, the work with locking cylinder 2
Stopper rod is fixedly connected, and the other end of pressing plate 3 is arranged on main shaft 8, is flexibly connected with main shaft 8, the junction of pressing plate 3 and main shaft 8
Bearing hole is provided with, bearing 4 is provided with bearing hole, bearing hole is provided with bearing cap 5.
When using, drilling rod is connected through a screw thread with the end of main shaft 8, locking cylinder 2 leads to pressure oil, the work of locking cylinder 2
Stopper rod stretches out, and promotes the pressing plate 3 on piston rod to move, and pressing plate 3 promotes the relative main 8 of lock sleeve 6 to slide, and compresses and the spiral shell of main shaft 8
The drilling rod end face of line connection, increases thread friction power, reaches the purpose of locking drilling rod.
The present invention to be threadedly coupled between main shaft 8 and drilling rod principle analyse in depth on the basis of, by increase main shaft 8 and
Normal pressure between drilling rod between screw connection structure end face increases thread friction resistance, and causes this frictional resistance more than boring
Power needed for machine Automated shackle, prevents the threaded connection between main shaft 8 and drilling rod from surprisingly releasing, and reaches the mesh 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 modifications and change
Within the scope of the claims in the present invention and its equivalent technologies, then these modifications and modification are also in protection scope of the present invention for type
Within.
In the prior art that the content not described in detail in specification is known to the skilled person.
