Abstract
The invention discloses a spring type mechanical buffering and floating device of a drilling rig. The spring type mechanical buffering and floating device of the drilling rig comprises a power head, a main shaft is arranged inside the front end of the power head, a guide hole is formed in the center of the main shaft, a sliding block which can side back and forth inside the guide hole is arranged in the guide hole, the front end of the sliding block is connected with a connecting rod, the connecting rod is connected with a drill rod connector through a connecting device, and a pressure spring is arranged between the rear end surface of the connecting device and the front end of the power head. Therefore, the connecting rod is additionally arranged to achieve initial adjustments of floating strokes to meet various drilling requirements, and the elasticity of the spring is utilized to produce a floating axial stroke space, a mechanical floating stroke space is provided, meanwhile, workers can observe the working condition of the spring type mechanical buffering and floating device of the drilling rig anytime during working, so that misoperation can be reduced; the spring type mechanical buffering and floating device of the drilling rig is simple in structure, small in product processing difficulty and easy to install, facilitates installation and uninstallation under a mine and is applicable to operating environment under the mine.
Description
Technical field
The present invention relates to a kind of drilling equipment, specifically a kind of rig spring mechanical damping floating installation.
Background technology
A kind of important device of shackle drilling rod when mechanical float is rig work, mechanical float can not pulled by a mouthful assurance male and female screw thread when the shackle drilling rod, thereby have guaranteed application life and the operating efficiency of rig.The mechanical float of rig has both at home and abroad at present: the key slot type mechanical float; The drag-cup type mechanical float.
The key slot type mechanical float is to utilize the output of unit head leading portion end to be fixed with a flange, floating core pipe with keyway is wherein arranged, then with the upper end of drilling rod short circuit, dock, when unit head needs the unloading drilling rod, the drill rod thread width produces displacement to axial and passes to the drilling rod short circuit, the drilling rod short circuit promotes key slot type floating core pipe along the dynamic head main spindle axially-movable, the stroke that floats provides space to this axially-movable, reach floating effect, but when rig is drilled, the unit head sinciput, the operator who is closed due to the core pipe does not observe floating core pipe stroke to minimize, running into lithosphere, unit head is impacted, reduced the application life of unit head.
The drag-cup type mechanical float is to utilize the planker of fastening unit head and frame axially locating two locating pieces in fixing front and back, planker can freely be moved forward and backward, when unit head needs the unloading drilling rod, planker relatively and frame can carry out relative motion, between planker and front and back locating piece, distance provides space for this axially-movable, reach floating effect, but after in the mine poor working environment, insufficient light, distance between planker and locating piece is easily by sludge blockage, cause floating space not reach the stroke of unloading drilling rod needs, thereby easily pull the male and female screw thread between drilling rod, reduced the application life of drilling rod.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, reliable in action, and the stroke space is visible, the rig spring mechanical damping floating installation of long service life.
In order to solve the problems of the technologies described above, rig spring mechanical damping floating installation of the present invention, comprise a unit head, in the front end of unit head, main shaft is installed, the center of main shaft is provided with pilot hole, in pilot hole, is provided with before and after can be in pilot hole the slide block slided, and the front end of slide block is connected with a connecting rod, connecting rod is connected with tool joint by linkage, is provided with stage clip between the rear end face of linkage and the front end of unit head.
The front end of described unit head is provided with annular groove, and the rear end of linkage also is provided with annular groove, and the rear and front end of stage clip is arranged on respectively in the annular groove of the annular groove of unit head front end and linkage rear end.
After adopting above-mentioned structure, due to the main shaft with centre bore arranged, the slide block be connected with connecting rod arranged in pilot hole and the stage clip of setting, increase connecting rod and can accomplish initial adjustment to the stroke that floats, thereby adapt to various probing demands, simultaneously can utilize the spring scalability, produce the axial stroke space of floating; When being provided, mechanical float stroke space can also make the staff when work, observe at any time the duty of this device, thereby reduced maloperation, its product difficulty of processing simple in structure is little, easy for installation, be convenient to the installation and removal under ore deposit, meet the environment for use under mine.
The accompanying drawing explanation
Fig. 1 is the structural representation of rig spring mechanical damping floating installation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, rig spring mechanical damping floating installation of the present invention is described in further detail.
As shown in the figure, rig spring mechanical damping floating installation of the present invention, comprise a unit head 1, main shaft 2 is installed in the front end of unit head 1, the center of main shaft 2 is provided with pilot hole 3, in pilot hole 3, be provided with before and after can be in pilot hole the slide block 4 slided, the front end of slide block 4 is connected with a connecting rod 5, connecting rod 5 is connected with tool joint 6 by linkage, said linkage is a supported flange that can be connected with tool joint 6 by bolt, utilize thus bolt by supported flange, connecting rod 5 is connected with tool joint 6, between the front end of the rear end face of supported flange and unit head 1, be provided with stage clip 7, utilized thus the spring scalability, produce the axial stroke space of floating, when simultaneously borer drill rod runs into the lithosphere locking when the rig sinciput, reach the effect of buffering, and rig increases the impact force of unit head while drilling, improved operating efficiency.
Further can be provided with annular groove at the front end of unit head 1; the rear end of linkage also is provided with annular groove; the rear and front end of stage clip 7 is arranged on respectively in the annular groove of the annular groove of unit head 1 front end and linkage rear end; increased thus the stability that stage clip is installed; thus by increasing the stroke reset function of mechanical float; reduce the impact force that rig is subject to; when having protected rig; increased the safety of safe construction; improved operating efficiency and the stroke of mechanical float is accomplished to regulate, thereby having adapted to the use of various working environments.
