Description
Technical field
The present invention relates to a kind of construction equipment of bored socket pile, especially a kind of for salvaging when boring drop device of lower brill tooth of rock bit, belong to piling Technology field.
Background technology
Bored socket pile, because reliable in structure, bearing capacity are strong, is used widely in Foundation Design.Because rock is harder, when general boring, all adopt alloy steel rock bit or other alloy tool steel bit of axial and the multiple brill teeth of radial equipartition, the brill tooth of alloy steel rock bit is to be all welded on drill bit dish, in work progress due to wearing and tearing, collision, can cause boring tooth and drop, have a strong impact on carrying out smoothly of boring, if the brill tooth dropping is not taken out, not only affect boring progress, cause drill bit heavy wear, even cannot continue construction.Simultaneously embedding rock drilled pile casing or the hollow pile foundation in top can not be squeezed in hard basement rock, and the layer of sand on scar top is often connected with in hole, and after boring tooth and dropping in hole, existing method is difficult to salvage brill tooth, and for oblique socketed pile, difficulty is larger.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, can salvage easily the dropping of rock bit of boring tooth in boring hole bottom of dropping and bore tooth fishing device
The present invention is achieved by the following technical programs:
A kind of rock bit drops and bores the fishing device of tooth, comprise fishing socket and permanent magnet, the upper and lower side of described fishing socket is equipped with shrouding, drilling rod lower end is fixed on the upper-end closing plate centre of fishing socket, fishing socket barrel is provided with the lateral openings of up/down perforation, lower end-plate is provided with the radial slot of an end opening, and described lateral openings and radial slot connect; The inner center of circle of containing end-plate under fishing socket of described radial slot, the lower end-plate edge of fishing socket is led in radial slot outer end; Described permanent magnet is bar shaped, and it is upper and be positioned at outside radial slot one side that permanent magnet two ends are fixed on the lower end-plate inner side of fishing socket by spacer ferrule and securing member respectively.
Object of the present invention can also further realize by following technical measures.
Aforesaid rock bit drops and bores the fishing device of tooth, and the width of wherein said lateral openings or radial slot is greater than the width that bores tooth.
Aforesaid rock bit drops and bores the fishing device of tooth, wherein, in the upright projection of fishing socket, has the poor B of radial distance between the dual-side of lateral openings.
Aforesaid rock bit drops and bores the fishing device of tooth, and wherein said lower end-plate plate between permanent magnet and radial slot faces down and is inclined to the inclined-plane of sharp angle α, and the angle of described sharp angle α is 17 °～23 °; Fishing socket diameter is less than bore diameter 90～110mm, and fishing socket height is 300～400mm.
Aforesaid rock bit drops and bores the fishing device of tooth, and described fishing socket diameter is less than bore diameter 90～110mm, and fishing socket height is 300～400mm; The direction of rotation of described fishing socket is the direction that permanent magnet points to radial slot.
The present invention is simple in structure, easy to use, when drilling rod drives the fishing socket under it to put in the rotation of boring hole bottom, drop bore tooth and scum from the lateral openings of fishing socket barrel or the inclined-plane of end-plate enter in fishing socket, the strong magnetic field that is fixed on the permanent magnet generation on lower end-plate inner side adsorbs bores tooth and scum, the permanent magnet magnetic line of horizontal positioned is substantially enclosed in fishing socket, can not form chain adsorption phenomena because of external action.Use the present invention dropping of foot of hole can be bored to tooth and scum removing totally, avoid continuing to damage alloy steel rock bit or other alloy tool steel bit, improved the efficiency of construction of bored socket pile.
Advantage and disadvantage of the present invention, by for illustration and explanation the non-limitative illustration by preferred embodiment below, these embodiment, only provide as an example with reference to accompanying drawing.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Fig. 1 and Fig. 2, the present invention includes fishing socket 1 and permanent magnet 2, the upper and lower side of fishing socket 1 is equipped with shrouding, drilling rod 3 lower ends are welded on upper-end closing plate 11 centres of fishing socket 1, and by be distributed on its surrounding the soldered drilling rod 3 of 4 gussets 31 and upper-end closing plate 11, improve the bonding strength of drilling rod 3 and fishing socket 1.Fishing socket barrel 13 is provided with the lateral openings 131 of up/down perforation, and lower end-plate 12 is provided with the radial slot 121 of an end opening, and lateral openings 131 connects with radial slot 121.The center of circle of the radial slot 121 inner lower end-plates 12 that contain fishing socket 1, the edge of the lower end-plate 12 of fishing socket 1 is led in radial slot outer end 121.Fishing socket 1 diameter is less than bore diameter 90～110mm, is convenient to fishing socket 1 and enters in boring hole, and fishing socket 1 is highly 300～400mm.
As shown in Figure 2, the width C of radial slot 121 is greater than the width that bores tooth; In the upright projection of fishing socket, between the dual-side of lateral openings 131, there is the poor B of radial distance, such structure be more conducive to drop bore tooth enter in fishing socket 1 from lateral openings 131 or radial slot 121.
Permanent magnet 2 is bar shaped, locate by the spacer ferrule 4 being welded on lower end-plate 12 respectively at its two ends, permanent magnet 2 is fixedly connected with spacer ferrule 4 with nut 6 by trip bolt 5 again, thereby make to be fixed on lower end-plate 12 inner sides of fishing socket 1 at permanent magnet 2, permanent magnet 2 is set in parallel in outside radial slot 121 1 sides.
The plate of the lower end-plate 12 between permanent magnet 2 and radial slot 121 faces down and is inclined to the inclined-plane 122 of sharp angle α, and the angle of sharp angle α is 17 °～23 °, and the sharp angle α angle of the fishing socket 1 of the present embodiment is 20 °.The direction of rotation of fishing socket 1 is the direction that permanent magnet 2 points to radial slot 121, and fishing socket 1 direction of rotation of the present embodiment is clockwise direction.When fishing socket 1 rotates, inclined-plane 122 plays the effect of spatula, makes to drop brill tooth and scum in inclined-plane 122 enters fishing socket 1, and is adsorbed on permanent magnet 2, reaches and salvages the object of boring tooth and scum.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
