Abstract

The invention discloses an anti-slip positioning drill device belonging to a hole guiding tool for installing drill holes in walls of pipelines. The anti-slip positioning drill device is shaped like two round pillars which have different sizes and are overlapped together. A small pillar is a drill stock fastener; a large pillar is tubular and is provided with a battlement-shaped saw blade block at an upper opening; the center of the bottom of a tube body is provided with a drill rod of which the head is higher than the saw blade block; when the anti-slip positioning drill device is used, the lower part of an anti-slip centring drill is fastened on a rotating shaft of a water drill; the head of the drill rod is oppositely pressed on a drilling point of a drilled object; a water valve and an electric switch are switched on; when the centring drill is drilled in a center-stabilizing hole with a certain depth under the condition that the centring drill is lubricated by using water, the drilled objected is cut from the surface to interior by the saw blade block by taking a centring drill rod and the center-stabilizing hole as rotating support points to form a ring groove with the depth of 1-2 cm, thus, a casing drill can continuously drill in the ring groove. Due to the adoption of continuous drilling through hole guiding, a standard hole can be drilled rapidly, stably and precisely, and the drill is not easily damaged.

Description

Locate anti-skidding drill bit device

Technical field

The present invention be piping erection be used for wall boring draw the hole apparatus.

Background technology

Piping erection at present mainly is on water bores, to add the encapsulation drill bit to the boring of wall, and wall is implemented punching.Use this drill bit punching; Must at first artificially on the brill thing, beat and dig out a 1-2 centimetre of dark shrinkage pool that is equal to bore diameter with the hammer pricker; Could go into the continuous brill of shrinkage pool with pipe bit; The hand chisel shrinkage pool is up to standard as not, drill bit will occur during continuous boring and acutely shake, and gets into the cave mouthful damaged and punching failure and drilling pipe shatters or drill lip falls phenomenons such as piece.

Summary of the invention

The present invention is directed to the problem of existing piping erection, decide the anti-skidding drill that draws in hole and designed to wall boring.The main feature of this special tool is: it is removed from when boring thing boring beating to cut a hole with the hammer pricker and draws the loaded down with trivial details of hole; Can be directly being installed in the anti-skidding drill bit device in location that water bores to being pressed on the brill point that bores thing; On the brill thing, draw the annular groove that cuts 2 centimetres of left and right sides degree of depth, going into the continuous brill of annular groove with pipe bit.

The primary structure of locating anti-skidding drill bit device by: the drilling pipe that connects on drillstock and the drillstock cuts the centralized positioning drilling rod that is provided with on sword and the drilling pipe centre and forms.The combining structure of its each parts is: establish the cylindricality drillstock in the bottom of drill body assembly, offer trapezoidal internal thread clamp nut at the central part of drillstock, open the groove of removing of cutting several indents at the middle part of drillstock.Cylindrical pipe box is established on the crown body bottom periphery top that is connected with drillstock top, establishes annular city wall buttress shape saw sword piece pipe box suitable for reading, on the central point of pipe box inner bottom part, establishes a centering drilling rod, and the drill bit that is located at drilling rod top is higher than saw sword piece.T font water channel is located on the central point of crown body bottom, and it is communicated with the space body of pipe box and nut.

Beneficial effect of the present invention is: 1, the centrifugal force of its rotation output is sprinkling upon the water throwing of injecting through T font water channel in the pipe box on the saw sword piece, and it is lubricated cooling and discharges muddy water.2, the drill bit length because of center pilot drill masthead portion exceeds band saw sword piece; When so drilling rod is holed on boring thing; At first by drill bit under the situation of boring the metancenter hole that pierces certain depth on the thing; The stingy moving saw sword piece that is connected as a single entity with it of annular pipe box is the swivel bearing point with centering drilling rod and metancenter hole, the brill thing is gone into the dark annular groove that carries out by table cut 1-2 centimetre of dark standard annular groove.3, coincide with the ring sword of pipe bit that continuous boring punches in the standard annular groove.Draw the continuous brill in hole that water is bored be stable through above-mentioned, accurately and fast get out gauge orifice, not fragile drilling tool.

The specific embodiment

Referring to Fig. 1-3, the anti-skidding drill bit device in a kind of location is formed drill body assembly 1 at two cylinders that vary in size; The big cylinder in drill body assembly 1 top is a pipe box 6, and the bottom paxilla is a drillstock 2, and the trapezoidal nut annular groove is offered at drillstock 2 middle parts; Make it become fastening drillstock nut 3, in drillstock 2, open the plane of cutting several indents on place's containment body and remove groove 4, on the outer containment body of the crown body 5 in drillstock 2 tops, establish circular pipe box 6; Cylindricality pipe box 6 is suitable for reading establishes annular city wall buttress shape saw sword piece 7, on the central point of the crown body 5 in cylindricality pipe box 6 bottoms, establishes a drilling rod 8; The drill bit 9 on drilling rod 8 tops is higher than saw sword piece 7; It is characterized in that T font water channel 10 is located on the central point of crown body 5 bottoms, it is communicated with the space body of pipe box 6 and nut 3.

The realization that the anti-skidding drill bit device in location of the present invention draws the hole principle is: be fastened on the clamp nut 3 that is located at drillstock 2 centres after water bores on the screw rod of take-off (propeller) shaft bar; Drawing drill to being pressed on the brill point that bores thing; The brill water of fetching boiling water cuts down the unlatching motor switch, and water bores take-off (propeller) shaft and rotates scratching moving drill bit assembly 1.

Rotary head assembly 1 mainly produces three functions when the rotation punching.1, the centrifugal force of its rotation output is sprinkling upon the water throwing of injecting through T font water channel 10 in the pipe box 6 on the saw sword piece 7, and it is lubricated cooling and discharges muddy water.2, drill bit 9 length because of centering drilling rod 8 tops, center exceed band saw sword piece 7 some millimeters; When so drilling rod 8 is holed on boring thing; At first by drill bit under the situation of boring the metancenter hole that pierces certain depth on the thing; Annular pipe box 6 is scratched and moved the saw sword pieces 7 that are connected as a single entity with it is the swivel bearing point with centering drilling rod 8 with the metancenter hole, the brill thing is gone into the dark annular groove that carries out by table cut 1-2 centimetre of dark standard annular groove.3, coincide with the ring sword of pipe bit that continuous boring punches in the standard annular groove.Draw the continuous brill in hole that water is bored be stable through above-mentioned, accurately and fast get out gauge orifice, not fragile drilling tool.
