Abstract
The utility model provides a be applied to combination formula drilling rod of twist bit, includes the body of rod, and the body of rod comprises integral key shaft, drill bit and double -screw bolt, and the shaping is at the upper and lower both ends of integral key shaft respectively for drill bit and double -screw bolt, and it has a plurality of helix group spare to peg graft on the integral key shaft, and helix group spare comprises at the flight of a list pitch of spline housing and welded fastening, and the head and the tail of the flight of adjacent helix group spare support by being in the same place through clamping piece, rivet riveting fixed together, it has the spacer to peg graft in the top of integral key shaft, the upper and lower both ends of spacer press respectively on the up end of helix group spare spline housing with fastening nut on, the fastening nut spiro union is on the double -screw bolt, the top spiro union of double -screw bolt has the rig connector. It has adopted the spiral drill rod of combination formula, and spiral drill rod comprises the body of rod, helix group spare, and during partial flight damage on spiral drill rod, only need to be changed corresponding helix group spare to whole root spiral drill rod, sparingly manufacturing cost do not need to be changed.
Description
Technical field:
The utility model relates to the technical field of spiral drilling machine, more specifically to a kind of combined drill rod being applied to spiral drilling machine.
Background technology:
The application of pile foundation construction boring machine in basic engineering construction is more and more extensive.And boring is generally realized by the spiral drilling machine of long screw drill rod on ground, existing long screw drill rod is generally entirety, when the flight parts against wear of the long spire on long screw drill rod during impact boring, need to change long screw drill rod, and long screw drill rod replacing can only change whole, comparatively waste.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of combined drill rod being applied to spiral drilling machine is provided, its long screw drill rod adopts combined type, and the breakage of part helix sheet only needs to change corresponding screw assembly, saves cost without the need to changing whole long screw drill rod.
Technology solution of the present utility model is as follows:
A kind of combined drill rod being applied to spiral drilling machine, comprise the body of rod, the body of rod is made up of splined shaft, drill bit and stud, drill bit and stud are molded over the two ends up and down of splined shaft respectively, splined shaft is plugged with several screw assemblies, screw assembly is made up of the flight of spline housing with the single pitch being weldingly fixed on spline housing, and the head and the tail of the flight of adjacent helical elements are abutted together and are fixed together by intermediate plate, rivet; The top of splined shaft is plugged with spacer, and on the upper surface that the two ends up and down of spacer are pressed against screw assembly spline housing respectively and on clamp nut, clamp nut is screwed onto on stud, and the top of stud is bolted with rig connector.
Conically, the maximum gauge of bit upper end is greater than the diameter of splined shaft to drill bit on the described body of rod.
The head and the tail two ends of described screw assembly flight form riveted holes, and the intermediate plate between adjoining spiral sheet is provided with two panels, and intermediate plate is resisted against the positive and negative of flight respectively, and the two ends of intermediate plate form locating hole.
The beneficial effects of the utility model are:
It has employed knockdown auger stem, and auger stem is made up of the body of rod, screw assembly, when the part helix sheet on auger stem damages, only needs to change corresponding screw assembly, thus does not need to change whole auger stem, saves cost of production.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model solid;
Fig. 2 is the structural representation that the utility model is faced;
Fig. 3 is the structural representation of the utility model body of rod;
Fig. 4 is the structural representation of the utility model screw assembly.
In figure: 1, the body of rod; 11, splined shaft; 12, drill bit; 13, stud; 2, screw assembly; 21, spline housing; 22, flight; 221, riveted holes; 3, spacer; 4, clamp nut; 5, rig connector; 6, intermediate plate; 61, locating hole.
Detailed description of the invention:
Embodiment: see shown in Fig. 1 to 4, a kind of combined drill rod being applied to spiral drilling machine, comprise the body of rod 1, the body of rod 1 is made up of splined shaft 11, drill bit 12 and stud 13, drill bit 12 and stud 13 are molded over the two ends up and down of splined shaft 11 respectively, splined shaft 11 is plugged with several screw assemblies 2, screw assembly 2 is made up of the flight 22 of spline housing 21 with the single pitch being weldingly fixed on spline housing 21, and the head and the tail of the flight 22 of adjacent helical elements 2 are abutted together and are fixed together by intermediate plate 6, rivet; The top of splined shaft 11 is plugged with spacer 3, and on the upper surface that the two ends up and down of spacer 3 are pressed against screw assembly 2 spline housing 21 respectively and on clamp nut 4, clamp nut 4 is screwed onto on stud 13, and the top of stud 13 is bolted with rig connector 5.
Conically, the maximum gauge of drill bit 12 upper end is greater than the diameter of splined shaft 11 to drill bit 12 on the described body of rod 1.
The head and the tail two ends of described screw assembly 2 flight 22 form riveted holes 221, and the intermediate plate 6 between adjoining spiral sheet 22 is provided with two panels, and intermediate plate 6 is resisted against the positive and negative of flight 22 respectively, and the two ends of intermediate plate 6 form locating hole 61.
Operating principle: the utility model is a kind of knockdown auger stem, auger stem is made up of the body of rod 1, screw assembly 2 etc., when the flight 22 on auger stem is damaged, only need the screw assembly 2 changing the breakage of corresponding flight 22, thus do not need to change whole auger stem.
