Abstract
The utility model relates to a bored pile drill bit picker, which is characterized in that a connecting flange and a bored pile drill rod standard joint are connected via bolts; a lifting plate is welded at the lower side of the connecting flange; the lower end of the steel wire is connected with an ear plate and the upper end is fixed with the lifting plate via a clasp; the ear plate is welded at the upper part of the end of a cross connecting rod; and a barb is connected with the cross connecting rod via a pin. The utility model has the advantages that the bored pile drill bit picker has simple manufacture, low cost and simple operation, and is suitable for picking the bored pile drill bit dropped in bore caused by cut drill bit flange bolt, and picking the drill bit without drill rod left in drop. In the lowering process of the picker, and when the picker touches the drill bit flange, the barb can automatically open via the wedge component force, and in the rising process of the picker, the barb can automatically clip the drill bit flange via gravity, to successfully pick the drill bit dropped by the cut drill bit flange bolt.
Description
Technical field
What the present invention relates to is a kind of drill extractor of bored pile, is applicable to when the drilled pile drill bit comes off that no remaining rod bit is salvaged on it, belongs to the construction foundation working technical field.
Background technology
Along with greatly developing of China's communications and transportation, the effect of bridge in highway, railway becomes increasingly conspicuous, bridge adopts bored pile foundation morely in design, drill bit and drilling rod break away from, drill rod breaking and have once in a while in the drilled pile drilling construction process, and drill bit is dropped at the bottom of the hole.Made by steel material because of drill bit, the drill bit that falls at the bottom of the hole must in time be salvaged, otherwise in case hole wall collapse can cause drill bit to scrap, pile foundation such as scraps at serious consequence, and the dawn is incured loss through delay the construction period, and economic loss is also very huge.The drill bit reason is multiple owing to coming off, and is various informative, only can not be suitable for the drill bit that form of ownership comes off with a kind of fisher.
Summary of the invention
The purpose of this utility model is intended to overcome the above-mentioned defective of existing in prior technology, a kind of drill extractor of bored pile is proposed, it is transferred in the process at fisher, when fisher runs into the drill bit flange, barb opens automatically because of wedge surface component, during rising, the drill bit flange is blocked in action of gravity automatically, successfully salvages because of drill bit and drill bit flange bolt and cuts off the drill bit (being no remaining drilling rod on the drill bit) that comes off.
Technical solution of the present utility model: its structure is to comprise adpting flange, boatswain chair, snap ring, wire rope, otic placode, bearing pin, cross connecting rod, barb composition; Wherein adpting flange links to each other with bolt with drilled pile drilling rod standard knot, boatswain chair is welded on the adpting flange, the upper end was fixed with snap ring and boatswain chair after otic placode was passed in the wire rope lower end, equally distributed 4 otic placodes are welded on the top of cross connecting rod end, and 4 barbs are fixed by bearing pin and cross connecting rod.
Advantage of the present utility model: this fisher manufacture craft is simple, and cost is low, and is easy to operate, is applicable to that the drill bit flange bolt cuts off, comes off and fall into drill bit stake drill bit at the bottom of the hole, when promptly coming off on it drill bit of no remaining drilling rod salvage.
Description of drawings
Fig. 1 is that the drill bit fisher is transferred the state elevation
Fig. 2 is a drill bit fisher propradation elevation
Fig. 3 is a drill bit fisher A-A profile
Among the figure 1 is adpting flange, the 2nd, boatswain chair, the 3rd, snap ring, the 4th, wire rope, the 5th, otic placode, the 6th, bearing pin, the 7th, cross connecting rod, the 8th, barb.
The specific embodiment
The drill bit fisher course of work, the fisher adpting flange is connected with bolt with the borer drill rod standard knot, makes fisher can utilize the length of borer drill rod, accurately arrives the drill bit position and salvages.Equally distributed 4 its ends of barb are connected to bascule by bearing pin and cross connecting rod, when fisher is transferred to the hole bit location, the wedge surface of barb end is contact drill bit flange earlier, and the fisher barb opens it because of the component of wedge surface automatically, and fisher is smoothly by the drill bit flange; When fisher upwards promoted, barb blocked the flange of drill bit automatically, and drilling tool can successfully be realized with the lifting of drilling rod salvaging.
Claims (2)
1, a kind of drill extractor of bored pile, it is characterized in that adpting flange links to each other with bolt with drilled pile drilling rod standard knot, boatswain chair be welded on adpting flange below, the wire rope lower end is connected with otic placode, the wire rope upper end is fixed with snap ring and boatswain chair, otic placode is welded on the top of cross connecting rod rod end, and barb links to each other with the cross connecting rod with bearing pin.
2, a kind of drill extractor of bored pile according to claim 1 is characterized in that described otic placode has 4, and described barb has 4.
