Abstract
The utility model discloses a drilling tool and belongs to the technical field of engineering machinery. The drilling tool comprises a drilling rod and the front end of the drilling rod is fixedly provided with a triangle drilling plate. The drilling tool can reach the requirement of a continuous pile-making construction method of tube-internal pump pressure concretes.
Description
Technical field
The utility model belongs to technical field of engineering machinery, is specifically related to a kind of drilling tool.
Background technology
It is a kind of advanced person's in the building operations technology that the pump pressure in pipe concrete continuous becomes pile work method (being called for short rearmounted reinforcing cage technology).After this arts demand drilling tool bores good stake hole, when drilling tool is carried brill, need fluid concrete simultaneously, when drilling tool was extracted fully, concrete pouring finished, and before concrete formation, inserted reinforcing cage at last.This technology can reduce construction cost greatly, and efficiency of construction is provided.
Existing common drilling tool does not also become pile work method special-purpose to the pump pressure in pipe concrete continuous, and mostly common drilling tool is the conveyor screw shape, can not reach the requirement that the pump pressure in pipe concrete continuous becomes pile work method.
The utility model content
The purpose of the utility model is to address the above problem and a kind of drilling tool is provided.This drilling tool can reach the requirement that the pump pressure in pipe concrete continuous becomes pile work method.
The technical scheme that the utility model adopted is:
A kind of drilling tool comprises drilling rod, and said drilling rod front end is fixed with three angular bit plates.
Further, said three angular bit front edge of board are fixed with drill bit.
Further, be fixed with door closure in the middle part of the said three angular bit plates.
Further, said three angular bit plate both sides are fixed with wearing layer.
Preferably, said drill bit is fixed on said three angular bit front edge of board through the mode of welding.
Preferably, said door closure is fixed on said three angular bit plates middle part through the mode of welding.
Preferably, said wearing layer is fixed on said three angular bit plate both sides through the mode of welding.
Preferably, the material of said three angular bit plates is the Q235 steel.
The utlity model has following advantage:
(1) this device can reach the requirement that the pump pressure in pipe concrete continuous becomes pile work method;
(2) this apparatus structure is simple, and result of use is good, long service life, and construction costs is low, and sedimentation is little, and effect is high;
(3) front end of this device intermediate cam brill plate is fixed with drill bit, has and well goes into the rock function;
(4) in this device door closure is installed, when drilling tool crept into, door closure was closed, and can prevent that like this rock from getting into drilling rod, and when drilling tool was carried brill, door closure was opened naturally, can better let concrete get into a stake hole.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
The structural representation of a kind of drilling tool that Fig. 1 provides for the utility model embodiment 1.
The specific embodiment
Embodiment 1
With reference to Fig. 1, a kind of drilling tool comprises drilling rod 1, and the material that drilling rod 1 front end is welded with three angular bit plates, 2, three angular bit plates 2 is the Q235 steel.Three angular bit plates, 2 front ends are welded with a plurality of drill bits 3.Three angular bit plates, 2 middle parts are welded with door closure 5.Three angular bit plates 2 are drilling rod 1 and the connector of drill bit 3, door closure 5, also are the main supporting bodies of cutting force simultaneously.The effect of drill bit 3 is cutting ground, and drilling tool is constantly crept into downwards.Three angular bit plates, 2 both sides are welded with wearing layer 4, and wearing layer 4 can reduce the wearing and tearing of drilling tool, improve the durability of drilling tool.
When the work of this device, drilling tool bores the stake hole, and door closure 5 is closed, and prevents that ground from getting into drilling rod 1.After the stake hole drill was good, when drilling tool was carried and being bored, cast mixed earth, and this moment, door closure 5 was opened, and door closure 5 is just as one the umbrella, better let a concrete inflow hole.When drilling tool was extracted fully, concrete was also poured into a mould and is finished, and in concrete, inserted reinforcing cage at last before the moulding.
Embodiment 2
What present embodiment and embodiment 1 were different is that the front end of three angular bit plates 2 does not have tipped drill 3.Three angular bit plates 2 are cutting body independently, but the drilling tool of this embodiment is gone into the poor effect of rock.
It should be noted last that; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
Claims (8)
1. a drilling tool is characterized in that, comprises drilling rod, and said drilling rod front end is fixed with three angular bit plates.
2. drilling tool according to claim 1 is characterized in that, said three angular bit front edge of board are fixed with drill bit.
3. drilling tool according to claim 1 and 2 is characterized in that, said three angular bit plate both sides are fixed with wearing layer.
4. drilling tool according to claim 3 is characterized in that, said wearing layer is fixed on said three angular bit plate both sides through the mode of welding.
5. drilling tool according to claim 4 is characterized in that, said three angular bit plates middle part is fixed with door closure.
6. drilling tool according to claim 5 is characterized in that, said door closure is fixed on said three angular bit plates middle part through the mode of welding.
7. drilling tool according to claim 2 is characterized in that, said drill bit is fixed on said three angular bit front edge of board through the mode of welding.
8. drilling tool according to claim 1 is characterized in that, the material of said three angular bit plates is the Q235 steel.
