Abstract
The utility model provides a drilling machine drill pipe fixing device which comprises two flange discs, two connecting rods, a sleeve and a bearing. One end of each connecting rod is used for being fixedly connected to a drilling machine oil cylinder, the other ends of the connecting rods are fixedly connected with the first flange disc, the sleeve is fixedly arranged between the first flange disc and the second flange disc, the bearing is clamped in the sleeve, the outer diameter of the bearing is tightly matched with the inner diameter of the sleeve, and a drilling machine drill pipe can penetrate through an inner hole of the bearing, so that swing of the drilling machine drill pipe is limited. The drilling machine drill pipe fixing device can effectively reduce the swing amplitude of the drilling machine drill pipe, and therefore hole drilling precision of a drilling machine is improved.
Description
Technical field
The utility model relates to plant equipment technology, relates in particular to a kind of borer drill rod fastening devices.
Background technology
In coal mine down-hole drilling work progress, originally generally use common rig, wherein a kind of is SGZ-300 rig.Use in SGZ-300 model drilling machine construction boring procedure, if punch position distance borehole drilling rig distance is larger, need to drive drill bit to carry out perforate operation compared with long drill pipe, due to borer drill rod is long and one end with drill bit, in the process of perforate, thereby drill bit is easy to whipping departs from punch position, make like this rig operation when punching drill bit alignment apertures position completely, perforate accuracy is not high.
Utility model content
The utility model provides a kind of borer drill rod fastening devices, cannot alignment apertures position to solve in prior art the easy whipping of drill bit, and the problem that perforate precision is not high.
The utility model embodiment provides a kind of borer drill rod fastening devices, comprising:
Two flange, two connecting rods, a sleeve and a bearing;
Described two connecting rod one end are respectively used to be fixedly connected with drill oil cylinder, and the described connecting rod other end is fixedly connected with the first flange, and described sleeve is fixedly installed between the first flange and the second flange;
Described bearing is arranged in described sleeve, described bearing outside diameter and sleeve diameter tight fit, and described brearing bore is used for wearing borer drill rod, to limit described borer drill rod whipping.
Further, above-mentioned connecting rod is connected with oil cylinder outer ring by clamp.
On described clamp, there are a plurality of bolts hole, by bolt, clamp are fixed on to drill oil cylinder outer ring.
Described two flange are bolted to connection.
The utility model embodiment borer drill rod fastening devices, by using connecting rod that two flange are fixed on drilling machine body, fixed muffle between two flange, sleeve diameter and bearing outside diameter tight fit, borer drill rod is arranged in brearing bore, thereby effectively limited the whipping of rig drilling rod in perforate operation process, and then improved the accuracy of perforation of boring machine.

The specific embodiment
Fig. 1 is the structural representation of the utility model borer drill rod fastening devices embodiment mono-, and as shown in Figure 1, the borer drill rod fastening devices that the present embodiment provides, comprising: two flange, two connecting rods, a sleeve 6 and a bearing 7; One end of head rod 41 is fixedly connected with drill oil cylinder 21, the other end is fixedly connected with a side of the first flange 51 outer ring grooves, one end of the second connecting rod 42 is fixedly connected with drill oil cylinder 22, and the other end is fixedly connected with the opposite side of the first flange 51 outer ring grooves.Here be fixedly connected with the mode that can use welding, also can connect for other modes.Sleeve 6 is fixedly installed between the first flange 51 and the second flange 52, and bearing 7 is fastened in sleeve 6, and bearing 7 external diameters and sleeve 6 internal diameter tight fits, and bearing 7 endoporus wear borer drill rod 8, for limiting borer drill rod whipping.
The borer drill rod fastening devices that the present embodiment provides, by using connecting rod that two flange are fixed on drilling machine body, fixed muffle between two flange, sleeve diameter and bearing outside diameter tight fit, borer drill rod is arranged in brearing bore, thereby effectively limited the whipping of rig drilling rod in perforate operation process, and then improved the accuracy of perforation of boring machine.
Fig. 2 is the structural representation of the utility model borer drill rod fastening devices embodiment bis-, as shown in Figure 2, one end of the head rod 41 of borer drill rod fastening devices is fixedly connected with drill oil cylinder 21 by the first clamp 31, on the first clamp 31, there are a plurality of bolts hole, by bolt, the first clamp 31 is fixed on to drill oil cylinder 21 outer rings, the other end of head rod 41 is fixedly connected with a side of the first flange 51 outer ring grooves, one end of the second connecting rod 42 is fixedly connected with drill oil cylinder 22 by the second clamp 32, on the second clamp 32, there are a plurality of bolts hole, by bolt, the second clamp 32 is fixed on to drill oil cylinder 22 outer rings, the other end of the second connecting rod 42 is fixedly connected with the opposite side of the first flange 51 outer ring grooves.Here be fixedly connected with the mode that can use welding.Sleeve 6 is welded on the second flange, bearing 7 is fastened in sleeve 6, here sleeve 6 can be also other connectors for internal thread pipe, bearing 7 external diameters and internal thread bore tight fit, interior fiber tube internal thread is in order to increase friction rigid bearing 7 external diameters, bearing 7 endoporus wear borer drill rod 8, the second flange 52 and are fixedly connected with the first flange 51 by bolt, so that interior fiber tube and bearing 7 are fixedly installed between the first flange 51, the second flange 52.Borer drill rod is arranged in brearing bore, thereby has effectively reduced the whipping amplitude of drilling rod in perforate operation process, has improved perforate precision.
The borer drill rod fastening devices that the present embodiment provides, by using clamp that connecting rod is fixedly connected with drill oil cylinder, clamp is bolted on drill oil cylinder outer ring, can adjust clamp in the position of drill oil cylinder outer ring according to run of steel, so that drill bit reaches minimum wobble amplitude during perforation of boring machine.
Finally it should be noted that: each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit above; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
