Abstract
The utility model discloses an in-hole reamer. The in-hole reamer comprises a drill rod, an in-hole reamer barrel body, a push rod, and a stabilizing wheel. A conical slipper, a wedge shaped tool post, a spring and a column are arranged in the in-hole reamer barrel body. The drill rod pushes the conical slipper to move forwardly, so as to push the tool post; a diamond tool is pushed out of the in-hole reamer barrel body by the tool post and contacts with the hole wall rock; and the drill rod drives the in-hole reamer to rotate, so as to notch on the hole wall.
Description
Technical field
The utility model belongs to tunnelling, subsurface rock engineering and mining machinery technical scope, relate to make in a kind of geotechnics anchoring guider in the hole firm be fixed on a kind of device in the hole.
Background technology
The anchoring guider is to be widely used in a kind of equipment that adopt in tunnelling, subsurface rock engineering and stone digging hole in the hole, can realize carrying out the subsurface rock engineering with lower cost, has avoided using explosive and the unsafe factor that causes.The anchoring guider is to be used with diamond-wire saw in actual use in the hole, because the pulling force of rope saw work is bigger, tends to make that the anchoring guider gets loose in the hole after the running in the hole.Based on above problem and shortage, we have invented a kind of device that can reaming in the hole.Desired location expands and groove in the hole, and then be stuck in the tensioning key of anchoring guider in the hole in the groove fixing, thereby make the stable work of anchoring guider in the hole.
Summary of the invention
The utility model is a reamer in a kind of hole, can make anchoring guider in the hole more firm be anchored at desired location in the hole.The utility model is realized by following technical scheme: it is made up of reamer ladle body, push rod and steady wheel in drilling rod, the hole.Form by a conical slide block, two or more wedge shape knife rests, spring in the reamer ladle body in its mesopore; In the hole reamer ladle body front end porose in the reamer bung, in the hole in reamer bung and the hole reamer ladle body be connected by screw, the interior circle centre position of reamer bung has cylinder in the hole; Cylinder injects in the conical slide block after passing spring; The reamer bung has pipe outward in the hole, and round tube inner wall has screw, can make in the push rod precession pipe; Can fastening push rod after clamp nut is screwed, an other end of push rod is connected with steady wheel by bearing.The wedge shape knife rest of reamer is a head breadth in the hole, other one narrow, wide one has diamond segment, narrow one has " 7 " font turning head.What the conical slide block of reamer contacted with the wedge shape knife rest in the hole is local fluted.
The utility model is reasonable in design, and is simple in structure, and behaviour does conveniently, can effectively solve the problem that the anchoring guider gets loose in the hole in the hole.

The specific embodiment
The specific embodiment: reamer is made up of reamer ladle body (2), push rod (13) and steady wheel (15) in drilling rod (1), the hole in this hole.Form by a conical slide block (3), two or more wedge shape knife rests (4), spring (7) in the reamer ladle body (2) in its mesopore; The porose interior reamer bung (6) of reamer ladle body (2) front end in the hole; In the hole in reamer bung (6) and the hole reamer ladle body (2) be connected by screw (9); The interior circle centre position of reamer bung has cylinder (8) in the hole, and cylinder (8) passes spring (7) back and injects in the conical slide block (3), and the reamer bung has pipe (19) outward in the hole; Pipe (19) inwall has screw; Can make in push rod (13) the precession pipe (19), can fastening push rod (13) after clamp nut (12) is screwed, an other end of push rod (13) is connected with steady wheel (15) by bearing (14).The wedge shape knife rest (4) of reamer is a head breadth in the hole, other one narrow, wide one has diamond segment (5), narrow one has " 7 " font head (18) of turning.What the conical slide block (3) of reamer contacted with wedge shape knife rest (4) in the hole is local fluted.Reserve the position of cutting in the hole during use as required; Adjust the length of push rod (13); The nut (12) of screwing; Put reamer steady wheel (15) in this hole forward in the hole that needs cutting, head on the position of steady wheel (15) at the bottom of the hole with drilling rod (1), drilling rod (1) connects rig and water route outside the hole.Start rig and jacking drilling rod (1) in the hole; Drilling rod (1) heads on conical slide block (3) and travels forward; Conical slide block (3) outwards pushes wedge shape knife rest (4), ejects the diamond segment (5) on the wedge shape knife rest (4) outside the reamer ladle body (2), contacts with the hole wall rock.Reamer rotates under the drive of rig, makes diamond segment (5) cutting on hole wall.Water injection hole (11) is arranged in the drilling rod (1); Cooling water gets into conical slide block (3) in water injection hole (11), get in the reamer ladle body (2) again, and reamer rotates; Water flows out from delivery port (17); Cool off diamond segment (5) and take away rock dust, a part of in addition water delivery port (16) from behind flows out, and is used for taking away barrel interior (a 2) rock dust.At reamer ladle body (2) front end reamer bung (6) is arranged, be connected with reamer ladle body (2) through screw (9) and screw.The inner home position of reamer bung (6) has cylinder (8), and cylinder (8) passes spring (7), injects in the conical slide block, plays fixing spring (7) and keep conical slide block (3) on the center of circle, to do to seesaw.Reamer bung (6) outside is the pipe that inwall has screw, is convenient to have push rod (13) precession of screw.Can change the push rod (13) of suitable length according to groove depth, also can finely tune the cutting position, screw by clamp nut (12) with the precession degree of depth.Other one of push rod (13) is connected with steady wheel (15) through bearing (14).Steady wheel (15) heads at the bottom of the hole, can not rotate during work.Conical slide block (3) is gone up fluted, is convenient to wedge shape knife rest (4) and puts into also front and back slip.After cutting is accomplished; Outside the hole, haul out drilling rod (1); Drilling rod (1) drives conical slide block (3) and moves backward; Conical slide block (3) heads on wedge shape knife rest " 7 " font backward and turns (18), and diamond segment (5) is taken in the reamer ladle body (2), is convenient to whole reamer and extracts outside the hole.
