Detailed description of the invention
A kind of CFG pile driver augers of the present embodiment, it comprises drill body and flange connector, described drill body is arranged on flange connector upper end, it is characterized in that: described drill body both sides correspondence is provided with the fixing ear be fixedly connected with flange connector, described drill body and flange connector are bolted, described drill body is provided with spiral cutting sword, described spiral cutting sword is made up of helical blade one and helical blade two, described helical blade one and helical blade two are oppositely welded together to form the arched apex point of tapering.
Be described in further details the utility model below in conjunction with the drawings and specific embodiments, following explanation only facilitates those skilled in the art to understand.
As Fig. 1, shown in 2, a kind of CFG pile driver augers, it comprises drill body 1 and flange connector 2, described drill body 1 is arranged on flange connector 2 upper end, it is characterized in that: described drill body 1 both sides correspondence is provided with the fixing ear 9 be fixedly connected with flange connector 2, described drill body 1 and flange connector 2 are bolted, described drill body 1 is provided with spiral cutting sword 3, described spiral cutting sword 3 is made up of helical blade 1 and helical blade 25, described helical blade 1 and helical blade 25 are oppositely welded together to form the arched apex point 10 of tapering, described apex point 10 top is that the bow-shaped structural of tapering makes augers can be good at playing its positioning performance, described drill body 1 both sides correspondence is provided with the fixing ear 9 be fixedly connected with flange connector 2, described drill body 1 bottom correspondence is welded with two fixing ears 9, two fixing ears 9 are respectively arranged with screwed hole 8, described two fixing ears 9 are installed on flange connector 2 respectively, flange connector 2 is also equipped with screwed hole 8 at correspondence position, described drill body 1 and flange connector 2 to be fixed with bolt by corresponding screwed hole 8 and to connect, described drill body 1 bottom is set to inside annular slope, corresponding flange connector 2 is provided with outside annular slope, drill body 1 and flange connector 2 are just in time connected together.
As shown in Figure 1, described helical blade 1 is equal with helical blade 25 size shape, described helical blade 1 and helical blade 25 be oppositely after welding, drives helical blade 1 and helical blade 25 to rotate to produce power to position and broken time pile driver carries out work.Spiral groove is formed after described helical blade 1 and helical blade 25 weld, during piling, driven by motor drill body 1 rotates together, after the blade tip of spiral cutting sword 3 positions, under huge torsional interaction, drill body 1 travels forward, helical blade 1 and helical blade 25 are holed and beat hard object rapidly, the fragmentation circle that helical blade 1 and helical blade 25 are formed is ascending expansion, hard object is formed spiral groove after being welded by helical blade 1 and helical blade 25 after front end is broken and gets rid of, blocking up of broken thing can not be produced.
As shown in Figure 2, described spiral cutting sword 3 adopts Chromador material, Chromador material adopts carbon steel to be the low hydorgew sodium type coating tungsten carbide surfacing electrode of core wire, rely on diamondite transition in coating, deposited metal tungstenic amount 40 ~ 50%, autolyzed relatively good, can not produce fire by friction in generation when pile driver work High Rotation Speed, and shock resistance, the basic drill bit adopting Chromador material, spiral cutting sword 3 can use the length of 20 to 30 meters.
As Fig. 2, shown in 3, described drill body 1 is provided with protruding 6 with flange connector 2 junction, corresponding flange connector 2 is provided with groove 7, described projection 6 and groove 7 with the use of, the holding capacity with flange connections in augers work can be alleviated, the vibrations that described drill body 1 produces when work are larger, closely very large impact can not be caused on the progress of work if be connected with flange connector 2, and drill body 1 common at present and flange connector 2 are fixed together, when drill body 1 in the process worked weares and teares replacing time, the time of cost two hours is needed to carry out dismounting and change, lose time very much, the utility model adopts drill body 1 and flange connector 2 to be flexibly connected, dismounting can be carried out very easily change after bit wear, and the Chromador material that drill body 1 adopts, conveniently repair and reuse, the flange connector 2 that described drill body 1 arranges protruding 6 and correspondence is provided with groove 7 be used in combination, be fixed by bolt again, connect comparatively robust, add operating efficiency.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that and the foregoing is only specific embodiments of the invention; the protection domain be not intended to limit the present invention; all any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
