Abstract
The utility model discloses a kind of vertical shaft type core underground drill rig of tape gripper, rig body is provided with gyrator, gyrator rotates under the power set of rig drive, and produces the power crept into, and drives the drilling rod be arranged in gyrator cylinder to rotate; It is characterized in that, on the top of cylinder, arrange a upper clamper, upper clamper is arranged around the endoporus of cylinder, under slave mode, clamp drilling rod.Core underground drill rig of the present utility model, on gyrator top, is provided with clamper, when needed with clamp holder clamping drilling rod, does not adopt artificial or hoist engine to be fixed by drilling rod; Significantly reduce the time of auxiliary clamping, increase substantially drilling efficiency; Reduce the labour intensity of operator, ensure to creep into quality; When unloading bar, upper gripper lives drilling rod, is reversed by gyrator, produces and loosens, and then throw off between the drilling rod that two, front and back process is threaded, and conveniently unloads bar operation.
Description
Technical field
The utility model relates to a kind of boring rig, particularly relates to a kind of vertical shaft type core underground drill rig of tape gripper.
Background technology
At present, core-drill(ing) machine geological and mineral resource exploration, the hydrology, well and tunnel engineering bore pick construction etc. in be used widely.Vertical shaft type core-drill(ing) machine of the prior art, when especially vertically up or being obliquely drilled with hole in coal mine gallery, especially add drilling rod at needs, fall bar (drilling depth) time, all to adopt manually or drilling rod is fixed by hoist engine, is operating accordingly; This kind of mode of operation, is first that efficiency is comparatively slow, consumes too many non-cutting time; Secondly, for operator, also there is certain potential safety hazard; Again, when unloading bar, needs unclamp the drilling rod that two, front and back process is threaded, and these two drilling rods only have a velamen clamping energy stressed, an other foundation is originally in vacant state, or is entangled by wire rope, cumbersome when unloading bar, add the labour intensity of workman, and unload bar operation more slowly, efficiency is lower.Prior art core underground drill rig, typical structure as shown in Figure 1.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is the vertical shaft type core underground drill rig providing a kind of tape gripper, to improve drilling efficiency, to reduce labour intensity.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme: a kind of vertical shaft type core underground drill rig of tape gripper, comprise rig body, rig body is provided with gyrator, gyrator rotates under the power set of rig drive, produce the power crept into, drive the drilling rod be arranged in gyrator cylinder to rotate; It is characterized in that, on the top of cylinder, arrange a upper clamper, upper clamper is arranged around the endoporus of cylinder, under slave mode, clamp drilling rod.
Further feature is, described upper clamper, comprises slips, slip spider, pushing block, hydraulic circuit and return spring; Slips is arranged on slip spider, along the internal orifice dimension of cylinder to setting, and contact of incline plane between slip spider and pushing block, pushing block matches with hydraulic circuit, promotes pushing block and moves up and down vertically; Return spring is arranged on above pushing block, produces spring return function effect to pushing block.
Remarkable result of the present utility model is:
(1) on gyrator top, be provided with clamper, when needed with clamp holder clamping drilling rod, do not adopt artificial or hoist engine to be fixed by drilling rod.
(2) significantly reduce the time of auxiliary clamping, increase substantially drilling efficiency.
(3) reduce the labour intensity of operator, ensure to creep into quality.
(4) on this, clamper, when unloading bar, clamps drilling rod, is reversed by gyrator, produces and loosens, and then throw off between the drilling rod that two, front and back process is threaded, and conveniently unloads bar operation.
Accompanying drawing explanation
Fig. 1 is the front view of prior art core underground drill rig;
Fig. 2 is the structure chart of core underground drill rig of the present utility model;
Fig. 3 is upper holder structure figure of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Figure 2, a kind of vertical shaft type core underground drill rig of tape gripper, comprises rig body 1, rig body 1 is provided with gyrator 2, gyrator 2 rotates under the power set of rig drive, and produces the power crept into, and drives the drilling rod be arranged in gyrator 2 cylinder 3 to rotate.Above as prior art, be not described further at this.
Improvement of the present utility model, on the top of cylinder 3, arrange a upper clamper 4, upper clamper 4 is arranged around the endoporus of cylinder 3, under slave mode, clamp drilling rod.
See Fig. 3, upper clamper 4 of the present utility model, comprises slips 41, slip spider 42, pushing block 43, hydraulic circuit 44 and return spring 45; Slips 41 is arranged on slip spider 42, radial direction along the endoporus (drilling rod through hole) of cylinder 3 is arranged, contact of incline plane between slip spider 42 and pushing block 43, and pushing block 43 matches with hydraulic circuit 44, return spring 45 is arranged on above pushing block 43, produces spring return function effect to pushing block 43.After hydraulic circuit 44 is opened and is filled with hydraulic oil, pushing block 43 is pushed and axially upwardly moves, and due to the effect on inclined-plane, pushing block 43 promotes slip spider 42 and radially moves to center position, produces clamping force, clamping drilling rod.Pushing block 43 be pushed axially upwardly move time, return spring 45 is compressed, hydraulic circuit 44 close after, return spring 45 produces downward active force, promote pushing block 43 move axially downwards, slip spider 42 is retreated, removes the clamping force to drilling rod.
In figure, upper clamper 4 is connected by the top of bolt with cylinder 3, forms the syndeton of similar flange.
When needs unload bar operation, clamp a drilling rod above with clamper 4, gyrator 2 drives a drilling rod below to rotate backward, and produce between two drilling rods and unclamp moment of torsion, two drilling rods just can facilitate shackle.
The course of work of the present utility model: upper clamper 4 is positioned at the top of gyrator 2 cylinder 3, hydraulic circuit 44 is opened and is filled with hydraulic oil, pushing block 43 is pushed and axially upwardly moves, due to the effect on inclined-plane, pushing block 43 promotes slip spider 42 and radially moves to center position, produces clamping force, clamping drilling rod, under gyrator 2 dynamic action, produce and creep into effect, return spring 45 is compressed; After hydraulic circuit 44 is closed, acted on downwards on pushing block 43 by the return spring 45 compressed, pushing block 43 is moved down, slip spider 42 is retreated, removes the clamping force to drilling rod.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, as above-described embodiment hydraulic jack also annoying pressure telescoping cylinder or electric expansion cylinder replace, latch can adopt other dismountable fixed connecting piece to replace.
