Abstract
The utility model provides a new drill rod mechanism for a blast furnace hole tapping machine. The drill rod mechanism for the blast furnace hole tapping machine comprises a drill rod and a casing, wherein a projection is arranged at the end of the drill rod, an L-shaped groove with an opening is arranged on the casing, the drill rod stretches into the casing and the projection is stuck in the L-shaped groove. In the utility model, the projection on the drill rod is stuck in the L-shaped groove which is arranged on the casing, so the drill rod can be tightly engaged with the casing. When the drill rod or the casing needs to be replaced, the projection of the drill rod just needs to be slightly turned and then taken out along the groove, and therefore the components of the drill rod mechanism are replaced very conveniently. Meanwhile, if only a part of the drill rod or the casing is damaged, the drill rod and the casing are not need to be replaced together, and therefore the manpower and the material resources are saved.
Description
Technical field
The utility model is at the custom-designed a kind of drilling rod of tap hole of blast furnace drilling rod mechanism.
Background technology
The drilling rod that is used for blast furnace fire door taphole drilling machine, general way is to leave screw thread on the drilling rod now, in pipe box, leave corresponding track then, utilize corresponding track in screw thread on the drilling rod and the sleeve pipe, drilling rod is screwed in the pipe box this drilling rod, in use, because the high speed rotating of drilling rod, under this impact, screw thread and track contact site are easy to distortion, make drilling rod and pipe box be easy to stick together, when needs changed drilling rod, drilling rod was difficult to take out from pipe box, even and take out, track in the sleeve pipe is also destroyed, can not continue again to use, need the connected set pipe to change together, cause the inconvenience of work and the waste of material.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned defective that overcomes prior art, the novel drilling rod mechanism that provides that a kind of blast furnace fire door taphole drilling machine uses.The drilling rod mechanism that blast furnace fire door taphole drilling machine of the present utility model is used comprises drilling rod, sleeve pipe, is provided with projection at drill rod end, and sleeve pipe is provided with the L shaped groove of opening, and drilling rod stretches in the sleeve pipe, and projection is stuck in the L shaped groove.
In order to realize the utility model better, the opening of L shaped groove flushes with the telescopic opening.
Described projection can be cuboid.
Described projection is welded on the drilling rod or is one-body molded with drilling rod.
The end face that described projection contacts with L shaped groove is set to arc or pit.
The face that described L shaped groove contacts with projection is set to arc or pit.
The utility model, utilize the projection on the drilling rod to be stuck in the L shaped groove that is provided with on the sleeve pipe, like this, can make to engage closely, when needs are changed drilling rod or sleeve pipe, only needing change the projection of drilling rod slightly, takes out along groove to get final product, the parts of very convenient replacing drilling rod mechanism, simultaneously, if only break down certain part, do not need drilling rod and sleeve pipe more to change together, also saved material resources in the labor-saving while.
Description of drawings
Fig. 1 is the structural representation of the utility model drilling rod.
Fig. 2 is the utility model telescopic structural representation.
Embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is described, understand the utility model to help further, but protection domain of the present utility model is not limited in this.
As shown in drawings, Fig. 1 is the structural representation of the utility model drilling rod.In the end of drilling rod 1, be welded with the projection 2 of a rectangular shape, this projection also can be one-body molded with drilling rod.Fig. 2 is the utility model telescopic structural representation.Sleeve pipe 3 is provided with L shaped groove 4, and the opening of L shaped groove flushes with the telescopic opening.In use, drilling rod stretches in the sleeve pipe, and L shaped groove is used for accepting the projection of drilling rod, and projection enters along the opening of L shaped groove at the sleeve opening place, after integral body has been crossed the corner of L shaped groove, is stuck in after the rotation and gets final product in the groove.In the time will changing, drilling rod is got final product along shifting out after negative side is changeed slightly.The very convenient replacing of the utility model, and save material.
As the distortion of embodiment 1, the end face that described projection contacts with L shaped groove is set to arc or pit, and further feature is identical with the feature of embodiment 1.When the end face that contacts with L shaped groove when projection is set to arc or pit, can be stuck in better in the L shaped groove, thereby drilling rod and sleeve pipe are not fragile, prolong the work-ing life of drilling rod mechanism.Simultaneously in order better to accept, the face that L shaped groove contact with projection also can be set to arc or pit again, like this, can make the tightness degree that contacts of the further increase of projection and L shaped groove.
The foregoing description is a preferred implementation of the present invention; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
