Description
The present invention relates in a kind of hole of the vertical or inclination that is suitable on crisps such as rock, being drilled to the inner grooving tool for gravity type big diameter hole that especially is suitable in the deep hole of larger caliber, carrying out cutting.
Ftracture and separate rock at directional blasting commonly used aspect mining, stone mining and water conservancy, the highway construction, so that the smooth rule of its plane of disruption, in the rock big gun hole that has been drilled to, carve the wedge angle groove of certain rule, it is the stress groove, this not only can increase the spacing in big gun hole, reduce the quantity in big gun hole, and directional blasting is more effectively carried out, obtain smooth and regular explosion face.A kind of tool for grooving in hole is disclosed in application number is 89101387.3 Chinese patent, this chamfering tool is made of knife bar, cutter head, locator card, is provided with the guide-track groove of inclination on cutter head, be equipped with on the guide-track groove can before and after the blade that slides, can finish the task of cutting in the above-mentioned hole well, but, when the bore in cutting hole bigger, when the degree of depth is longer, often need very long knife bar, this not only operates very inconvenient, need repeatedly change the bar extension bar, and often influences the efficient of cutting.
The objective of the invention is to avoid above-mentioned deficiency and a kind of inner grooving tool for gravity type big diameter hole of carrying out cutting in the vertical or angling hole of larger caliber of being suitable for is provided, not only structure is comparatively simple for it, and easy to operate, and cutting efficient is also higher.
Purpose of the present invention is realized by following scheme: have a cutter head 3, cutter head 3 is provided with the axial guidance groove 9 that turns forward, dispose the blade 2 that slides before and after the energy on the guide-track groove, its difference is to be provided with and blade 2 corresponding empennages 4 at the afterbody of cutter head 3, and tail end also is equipped with rope fastening device.
According to such scheme, when the rope 6 of the rope fastening device of cutter head afterbody and a hoisting mechanism links, to good position, can carry out the cutting of upright opening, cutter head 3 is aloft owing to action of gravity is fallen, behind the hand-hole, stressed the making thereafter of blade 2 front ends moved, and blade opens voluntarily, reaches maximum radial dimension, and by the percussion of gravity, carry out cutting in the hole, carry on the rope 6, cutter head 3 is withdrawing thereupon, 2 reach retractions of blade, can make cutter head 3 avoid swaging clamp to withdraw from smoothly, and cutter head 3 is promoted to eminence again, repeat above-mentioned course of action, can finish the cutting task of upright opening easily, one guide groove plate 20 is set, with cutter head 3 phase configuration, in order to the track and the direction of control cutter head 3 whereabouts on hoisting mechanism, even cutter head falling direction and vertical line tilt at an angle, the present invention then can finish the cutting task in the vertical hole with certain gradient.In sum, though the present invention is simple in structure, but can carry out the cutting task of the vertical or angling hole of heavy caliber effectively, adopt flexible rope to connect, the degree of depth in hole can not be subjected to the restriction of cutter head length, thereby can make things convenient for and carry out the deep hole cutting effectively, this is an outstanding characteristic of the present invention, and empennage 4 is to guarantee the straight of deep hole cutting, adopts the gravity fall mode, make operating process also obtain further simplification, help to make in the hole cutting operation automation further perfect.
