Abstract
The utility model belongs to the technical field of drilling equipment, and particularly relates to a drilling stand column. The drilling stand column comprises a column body, wherein a through hole is formed in the center of the column body; the bottom of the column body is provided with a pedestal; the pedestal is provided with a convex edge; fixing holes are formed in four corners of the convex edge; and the column body is provided with thread. The drilling stand column has a simple structure; the stability performance of overall operation of the drilling stand column is enhanced; the weight of the drilling stand column per se is reduced, and drilling operation is highly facilitated.
Description
Technical field
The utility model belongs to rig apparatus technical field, relates in particular to a kind of boring column.
Background technology
The boring column is parts in the rig.The main effect of boring column is the instrument that is used for match-drill.On the base of the boring column that uses at present is that fixing hole directly is set, and base also is to be bar shape or rectangular-shaped.In the process that this type of boring column re-uses, because the uninterrupted motion for a long time of boring column, can be than being easier to make the fixedly shakiness of fixing hole, thus produce the phenomenon that the boring column breaks away from.And because base also is to be bar shape or rectangular-shaped, general base all is metal, and institute is unfavorable for operation so that weight lays particular stress on.
Summary of the invention
The purpose of the utility model is to solve above-described technical problem, and a kind of boring column is provided, and its technical scheme is following:
A kind of boring column comprises cylinder, and described cylinder center offers through hole, and the bottom of said cylinder is provided with base, and said base is provided with chimb, and four jiaos of said chimb are provided with fixing hole, and said cylinder is provided with screw thread.
Optimal way does, the described base supreme pyramid that shrinks gradually of serving as reasons down.
The boring column that the utility model provides is provided with chimb in the bottom, and four jiaos of said chimb are provided with fixing hole, make the design of fixing hole more rationalize, and makes that use is also more stable.And the base supreme pyramid that shrinks gradually of serving as reasons down can reduce the weight of the part of base, saves the raw-material while also to have alleviated the weight of base, more helps operation.
The utility model is simple in structure, strengthened the boring column overall operation stability with alleviated the weight of itself, more help bore operation.
Description of drawings
The sketch map of Fig. 1 the utility model.
The specific embodiment
Specify embodiment below in conjunction with Fig. 1:
A kind of boring column comprises cylinder 1, and described cylinder 1 center offers through hole 2, and the bottom of said cylinder 1 is provided with base 3, and said base 3 is provided with chimb 4, and four jiaos of said chimb 4 are provided with fixing hole 5, and said cylinder 1 is provided with screw thread 6.
Optimal way does, the described base 3 supreme pyramid that shrinks gradually of serving as reasons down.
Claims (2)
1. a boring column comprises cylinder, it is characterized in that, described cylinder center offers through hole, and the bottom of said cylinder is provided with base, and said base is provided with chimb, and four jiaos of said chimb are provided with fixing hole, and said cylinder is provided with screw thread.
2. boring column as claimed in claim 1 is characterized in that, the described base supreme pyramid that shrinks gradually of serving as reasons down.
