Abstract
The invention provides a drill rod fixing device of a drilling machine. The device comprises two flange plates, two connecting rods, a conical sleeve and a bearing, wherein one ends of the two connecting rods are respectively used for fixedly connecting with an oil cylinder of the drilling machine, and the other ends are fixedly connected with the first flange plate; the conical sleeve is fixed between the first flange plate and the second flange plate; the bearing is clamped in the conical sleeve; the outer diameter of the bearing is tightly clamped with the inner diameter of the conical sleeve; and an inner hole of the bearing is used for penetrating through a drill rod of the drilling machine to limit the swing of the drill rod of the drilling machine. The device can effectively fix the drilling machine to reduce the swing amplitude of the drill rod of the drilling machine so as to improve the drilling precision of the drilling machine.
Description
Technical field
The present invention relates to mine mechanism technology, particularly relate to a kind of borer drill rod fastening devices.
Background technology
In coal mine down-hole drilling work progress, originally generally use ordi-nary drilling machine, wherein one is SGZ-300 rig.Use in SGZ-300 model drilling machine construction boring procedure, if punch position distance borehole drilling rig distance is larger, comparatively long drill pipe is then needed to drive drill bit to carry out perforate operation, because the longer and one end of borer drill rod is with drill bit, in the process of perforate, drill bit is easy to whipping thus departs from punch position, and when making rig operation punch like this, drill bit can not alignment apertures position completely, and perforate accuracy is not high.
Summary of the invention
The invention provides a kind of borer drill rod fastening devices, cannot alignment apertures position to solve the easy whipping of drill bit in prior art, the problem that perforate precision is not high.
The technical scheme that the present invention solves the problems of the technologies described above is as follows, and a kind of borer drill rod fastening devices, comprising: the first flange, the second flange, head rod, the second connecting rod, conical sleeve and bearing; Described head rod and second connecting rod one end are respectively used to be fixedly connected with the second oil cylinder with the first oil cylinder of rig, described head rod is fixedly connected with the first flange with the second connecting rod other end, and described conical sleeve is fixedly installed between the first flange and the second flange.
Further, described bearing is arranged in described conical sleeve, and bearing outside diameter closely engages with conical sleeve internal diameter.
Further, described head rod is connected with the outer ring of the second clamp with the first oil cylinder and the second oil cylinder respectively by the first clamp with the second connecting rod.
Further, described first clamp and the second clamp there is multiple bolt hole, by bolt, the first clamp and the second clamp are separately fixed at the first oil cylinder of rig and the outer ring of the second oil cylinder.
Further, described first flange and the second flange are bolted to connection.
The invention has the beneficial effects as follows: bearing outside diameter closely engages with conical sleeve internal diameter, brearing bore is used for wearing borer drill rod, the whipping of further restriction borer drill rod, connecting rod is fixedly connected with drill oil cylinder by clamp, clamp is bolted on drill oil cylinder outer ring, the position of clamp in drill oil cylinder outer ring can be adjusted according to run of steel, during to make perforation of boring machine, drill bit reaches minimum wobble amplitude and effectively can fix rig, reduce the whipping amplitude of borer drill rod, and then improve perforation of boring machine accuracy.

Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
A kind of borer drill rod fastening devices as shown in Figure 1, one end of the head rod 41 of borer drill rod fastening devices is fixedly connected with the first oil cylinder 21 of rig 1 by the first clamp 31, first clamp 31 there is multiple bolt hole, by bolt, the first clamp 31 is fixed on the first oil cylinder 21 outer ring of rig 1, the other end of head rod 41 is fixedly connected with the side of the first flange 51 outer ring groove, one end of second connecting rod 42 is fixedly connected with the second oil cylinder 22 of rig 1 by the second clamp 32, second clamp 32 there is multiple bolt hole, by bolt, the second clamp 32 is fixed on the second oil cylinder 22 outer ring of rig 1, the other end of the second connecting rod 42 is fixedly connected with the opposite side of the first flange 51 outer ring groove.Here the mode that can use welding is fixedly connected with.Conical sleeve 6 is welded on the second flange, bearing 7 is fastened in conical sleeve 6, conical sleeve 6 can be internal thread pipe also can be other connectors, bearing 7 external diameter closely engages with conical sleeve 6 internal diameter, conical sleeve 6 internal thread is in order to increase friction rigid bearing 7 external diameter, bearing 7 endoporus wears borer drill rod 8, and the second flange 52 is fixedly connected with the first flange 51 by bolt, is fixedly installed between the first flange 51, second flange 52 to make conical sleeve 6 and bearing 7.Borer drill rod is arranged in brearing bore, thus effectively reduces the whipping amplitude of drilling rod in perforate operation process, improves perforate precision.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
