Abstract
The invention relates to a tubular reamer for drilled hole shaping. The tubular reamer comprises a reamer body which is of a tubular structure, the lower end of the reamer body is connected with a drilling tool, the tube wall of the reamer body is provided with multiple rows of mounting holes distributed in the axial direction of the reamer body, and alloy blocks are fixedly connected into the mounting holes. The tubular reamer is combined with the drilling tool, reaming is carried out on expanded holes, and shaping is conducted on the drilled holes; compared with traditional single drill-bit reaming, quality of the drilled holes is greatly improved.
Description
Technical field
The present invention relates to geological prospecting apparatus field, relate in particular to the drilling rod of rig.
Background technology
Drilling rod is the critical component in rig, and its end connects drilling tool.In prior art, the effect of drilling tool is that rock is rubbed, and carries out reaming, and it plays reaming effect, and its function singleness can not realize comprehensive fraising and shaping be carried out in hole.
Summary of the invention
The shortcoming that the applicant exists for above-mentioned prior art, studies and improves, and provides a kind of and can realize fraising comprehensively, the tubular reamer that hole is carried out to shaping.
The technical solution adopted in the present invention is as follows:
A tubular reamer for the shaping of holing, comprises reamer body, and reamer body is tubular structure, and its lower end connects drilling tool, and the tube wall of described reamer body is provided with many rows along the installing hole of its axial distribution, in described installing hole, is fixed with alloy block.
Further improvement as technique scheme:
Adjacent row's described installing hole is the setting of staggering.
Described alloy block growth list structure, its length direction is parallel with the axis of reamer body.
Described alloy block is welded in described installing hole.
Beneficial effect of the present invention is as follows:
Tubular reamer of the present invention combines with drilling tool, after reaming, is reamed in hole, and the shaping of holing is compared with traditional single drill bit reaming, greatly improves drilling quality.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present invention.
Fig. 2 is front view of the present invention.
In figure: 1, reamer body; 11, installing hole; 2, alloy block.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, the tubular reamer for the shaping of holing of the present embodiment, comprise reamer body 1, reamer body 1 is tubular structure, its lower end connects drilling tool (not shown), the tube wall of reamer body 1 is provided with many rows along the installing hole 11 of its axial distribution, adjacent row's installing hole 11 is the setting of staggering, in installing hole 11, be welded with alloy block 2, alloy block 2 growth list structures, by antifriction alloy, made, its length direction is parallel with the axis of reamer body 1, and the alloy block 2 of strip is convenient to the rock after broken by hinge derives.
Tubular reamer of the present invention combines with drilling tool, after reaming, is reamed in hole, and the shaping of holing improves drilling quality.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.
