Abstract
The utility model relates to a clamping tool for a drill pipe of a small-aperture drilling machine. The clamping tool consists of a hollow operation rod, an operation handle, an arc control sleeve communicated with the hollow operation rod, two inner rings matched with the arc control sleeve, two springs and a steel wire rope; the two inner rings are symmetrically located at the left side and the right side of a cavity of the control sleeve; one end of the spring is connected with the inner wall of the arc control sleeve, which is close to a lowest point; the other end of the spring is connected with one ends of the inner rings, which are close to the lowest point of the control sleeve; a limiting groove is arranged at one end of the hollow operation rod; one end of the steel wire rope, which passes through the hollow operation rod, is connected with the operation handle through a limiting groove, and the other end of the steel wire rope is divided into two strands in the control sleeve; and the two strands of the steel wire rope are respectively connected with the ends of the inner rings, which are close to the lowest point of the control sleeve. The clamping tool for the drill pipe of the small-aperture drilling machine is mainly used for drilling an explosion hole and a mounting hole for supporting an anchor rod and an anchor rope in a coal tunneling process, so that with the adoption of the clamping tool, the drilling machine can be ensured to stably and smoothly drill in a drilling process; a hole position and a hole angle quality can be qualified; and a person who holds the drill pipe is prevented from being hurt due to the breaking of the drill pipe or the hinging of a twist drill pipe.
Description
Technical field
The utility model relates to a kind of borer drill rod clamping device, more particularly relates to a kind of small-bore rig (bore diameter 28～43mm) drilling rod clamping devices.
Background technology
In the digging activity of colliery, the small-bore rig is mainly used in the jewel hole perforate with installing hole of shot hole and anchor pole, cable bolting.This type of borer drill rod length is generally 2.0～3.0m, bore diameter 28～43mm, and the rig operating personnel are beyond rod bit 2.0m during work; Can not control drill bit voluntarily and accomplish jewel hole perforate operation; Need treat that drill bit gets into after coal petrography 100～200mm by professional's (being commonly called as neck pricker worker) with holding the cylindrical drill bar, the holding rod personnel can withdraw; Be prone to take place drill rod breaking and injure accidents such as holding rod personnel, the twist drill rods hinge person of hurting sb.'s feelings; In fact in the Coal Production process, above-mentioned accident often takes place, and safety in production is constituted a threat to.At present, still do not have and be specifically designed to guiding small-bore rig jewel hole perforate and carry out smoothly, and guarantee the instrument of eye position, canthus quality.
Summary of the invention
The purpose of the utility model is to provide a kind of small-bore borer drill rod clamping device; This instrument can guarantee that the perforate of rig jewel hole steadily carries out smoothly; Eye position, canthus are up-to-standard; Owing to do not need personnel to grasp borer drill rod, also avoided drill rod breaking to hurt the generation that holding rod personnel, twist drill rods hinge hinder holding rod personnel accident.
For realizing above purpose; The utility model is realized through following technical scheme: small-bore borer drill rod clamping device encircles by hollow action bars, operating handle, the circular arc control cover that is communicated with the hollow action bars, in cooperate with circular arc control cover two, two springs and wire rope constitute; The ring symmetry is positioned at control cover cavity the right and left in two; Spring one end connects near the inwall the circular arc control cover minimum point; Ring and that nearer end of control cover minimum point in the other end connects; One end of hollow action bars has stopper slot, and wire rope one end that runs through the hollow action bars is through stopper slot attended operation handle, the other end in the control cover, be divided into connect respectively after two strands in ring overlap that nearer end of minimum point with control.
As the further improvement of the utility model, the hollow action bars is tapered near an end of control cover, thereby can insert in the crack of coal rock layer, and the other end grasps, and so just can guarantee that small-bore borer drill rod clamping device can not rock.
The utility model can produce following beneficial effect: owing to used small-bore borer drill rod clamping device; The holding rod personnel just need directly not hold borer drill rod with hand; Avoided drill rod breaking to hurt the generation that holding rod personnel, twist drill rods hinge is hindered accidents such as holding rod personnel; And small-bore borer drill rod clamping device can guarantee that the jewel hole perforate steadily carries out smoothly, also can guarantee the quality at eye position, canthus.
Description of drawings
Fig. 1 is the front view of small-bore borer drill rod clamping device.
Fig. 2 is the vertical view of small-bore borer drill rod clamping device.
Fig. 3 and Fig. 4 are the partial sectional views of Fig. 1, and wherein Fig. 3 is a control cover uncovered state (off working state), and Fig. 4 is a control cover closure state (duty).
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; Small-bore borer drill rod clamping device by hollow action bars 3, operating handle 5, the circular arc control cover 7 that is communicated with hollow action bars 3, overlap 7 with circular arc control and encircle 8, two springs 9 in cooperate two and wire rope 10 constitutes; Ring 8 symmetries are positioned at control cover 7 cavity the right and lefts in two; Spring 9 one ends connect near the inwall circular arc control cover 7 minimum points; Ring 8 and that nearer end of control cover 7 minimum points in the other end connects, an end of hollow action bars 3 has stopper slot 6, and wire rope 10 1 ends that run through hollow action bars 3 are through stopper slot 6 attended operation handles 5; The other end in control cover 7, be divided into connect respectively after two strands in ring 8 and that nearer end of control cover 7 minimum points, it is tapered that action bars 3 overlaps an end of 7 near control.
Fig. 3 is the partial sectional view of Fig. 1, is in off working state, operating handle 5 tensions this moment, and spring 9 compressions, interior ring 8 shrinks, and control cover 7 is uncovered.
Fig. 4 is the partial sectional view of Fig. 1, and is in running order, and this moment, operating handle 5 unclamped, spring 9 resiliences, and interior ring 8 stretches out, control cover 7 closures.
Concrete method for using is: with 5 tensions of the operating handle in the stopper slot 6, interior ring 8 shrinks, and is in off working state; Borer drill rod is put in the groove of control cover 7, the unclamp operation handle 5 again, spring 9 resiliences in the control cover 7; Interior ring 8 stretches out, and control cover 7 closures are in running order.
