Abstract
The invention discloses a drilling hole guiding and centering device of a drilling machine. A press plate (6) is provided with a center hole which is convenient for a drilling rod and an impactor to pass through; in addition, the press plate (6) is also provided with a first rotating shaft (5) and a second rotating shaft (15) which are symmetrical relative to the center hole, wherein the first rotating shaft (5) is provided with a first guiding groove (12); the second rotating shaft (15) is provided with a second guiding groove (2); and when the first guiding groove (12) and the second guiding groove (2) are closed, the diameters of the first guiding groove (12) and the second guiding groove (2) are suitable for the drilling rod to pass through in a guiding and centering manner. The drilling hole guiding and centering device of the drilling machine can prevent the drilling rod from deflecting during drilling hole and dust and ashes generated by drilling holes from upwards emitting as well as the dust and ashes from flying.
Description
Technical field
The present invention relates to a kind of guiding and centering device, particularly relate to a kind of drilling hole guiding and centering device of drilling machine.
Background technology
Rig is widely used in Drilling shot hole in the engineerings such as metallurgy, mine, building materials, railway, construction of hydropower facilities, national defense construction and the cubic metre of earth and stone.In rig when boring,, ore was inhomogeneous because the influence of geological conditions, caused during boring that drilling rod beat and wearing and tearing, big gun hole are not straight, was not easy to blasting charge, was easy to generate dust from flying, and contaminated environment makes operating personnel suffer from pneumoconiosis, makes machine produce wearing and tearing simultaneously.
Summary of the invention
Technical problem to be solved by this invention prevents the drilling hole guiding and centering device of drilling machine of drilling rod beat when providing a kind of boring.
In order to solve the problems of the technologies described above, drilling hole guiding and centering device of drilling machine provided by the invention, pressing plate is provided with is convenient to the centre bore that drilling rod and impactor pass through, be provided with on described pressing plate with described centre bore is first turning cylinder and second turning cylinder of symmetry, on described first turning cylinder, be provided with first gathering sill, be provided with second gathering sill on described second turning cylinder, the suitable drilling rod pilot centering of its diameter passed through when described first gathering sill and described second gathering sill closed up.
Described first gathering sill is installed on described first turning cylinder by first connecting bolt, and described second gathering sill is installed on described second turning cylinder by second connecting bolt.
Below described pressing plate, be provided with the cup-shaped seal closure, longitudinal center line when the longitudinal center line of described cup-shaped seal closure closes up with described first gathering sill and described second gathering sill overlaps, and is provided with annular seal plate between described cup-shaped seal closure and described pressing plate.
Adopt the drilling hole guiding and centering device of drilling machine of technique scheme, simple in structure, easy to manufacture, easy for installation.It is installed on the dust hood of rig, and rig advances while drilling rod rotates when boring, carries out centering pilot by two gathering sills, prevents the drilling rod beat, guarantees that big gun hole straightness accuracy is good, is beneficial to blasting charge.The moving axis upset that can rotate of two gathering sills is beneficial to impactor and passes through.Taking bolt apart after the gathering sill wearing and tearing can change.The dirt slag that produces when cup-shaped seal closure, annular seal plate and two gathering sills can prevent to hole is upwards emerged, and prevents that the dirt slag from flying upward.Reduce environment pollution, the wearing and tearing of protection operating personnel's health and minimizing machine.
The present invention has following tangible advantage:
(1), the centering pilot of holing, prevent the drilling rod beat, guarantee that big gun hole straightness accuracy is good, be beneficial to blasting charge.
(2), the dirt slag that produces in the time of preventing to hole upwards emerges, and prevents that the dirt slag from flying upward.Reduce environment pollution, the wearing and tearing of protection operating personnel's health and minimizing machine.
(3), taking bolt apart after the gathering sill wearing and tearing can change.
In sum, the present invention prevents the drilling rod beat when being a kind of boring and the dirt slag that produces can prevent to hole the time is upwards emerged, and prevents the drilling hole guiding and centering device of drilling machine that the dirt slag flies upward.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is a stereogram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2 and shown in Figure 3, pressing plate 6 is provided with is convenient to the centre bore 9 that drilling rod and impactor pass through, first compact heap 8 is installed on the pressing plate 6 by first hold-down bolt 7, second compact heap 13 is installed on the pressing plate 6 by second hold-down bolt 11, it is first turning cylinder 5 and second turning cylinder 15 of symmetry that first compact heap 8 and second compact heap, 13 two ends are provided with centre bore 9, on first turning cylinder 5, first gathering sill 12 is installed by first connecting bolt 10, on second turning cylinder 15, second gathering sill 2 is installed by second connecting bolt 1, the suitable drilling rod pilot centering of its diameter passed through when first gathering sill 12 and second gathering sill 2 closed up, below pressing plate 6, be provided with cup-shaped seal closure 3, longitudinal center line when the longitudinal center line of cup-shaped seal closure 3 closes up with first gathering sill 12 and second gathering sill 2 overlaps, and is provided with annular seal plate 4 between cup-shaped seal closure 3 and pressing plate 6.
As Fig. 1, Fig. 2 and shown in Figure 3, drilling hole guiding and centering device of drilling machine of the present invention is simple in structure, and is easy to manufacture, easy for installation.It is installed on the dust hood of rig, and rig advances while drilling rod rotates when boring, carries out centering pilot by first gathering sill 12 and second gathering sill 2, prevents the drilling rod beat, guarantees that big gun hole straightness accuracy is good, is beneficial to blasting charge.
First gathering sill 12 and second gathering sill 2 can be beneficial to impactor and pass through respectively around first turning cylinder 5 and 15 upsets of second turning cylinder.
Take first connecting bolt 10 respectively apart after first gathering sill 12 and the wearing and tearing of second gathering sill 2 and second connecting bolt 1 can be changed.
The dirt slag that produces when cup-shaped seal closure 3, annular seal plate 4, first gathering sill 12 and second gathering sill 2 can prevent to hole is upwards emerged, and prevents that the dirt slag from flying upward.Reduce environment pollution, the wearing and tearing of protection operating personnel's health and minimizing machine.
