Background technology:
Later stage the 1950's abroad begins to adopt more piece reaming stake in expansive soil, abroad also begins the sixties, the seventies to use in black cotton regur soil, loess, lam, clay and sand.Experience shows that the reaming stake compares with straight hole pile, and bearing capacity improves greatly, and sedimentation is little, technical economic benefit is remarkable.The later stage seventies, domestic this technology of bringing into use.The nineties, Beijing Zhang Junsheng was invented hydraulic pressure extruding-enlarging branch tray forming machine, used in ground engineerings such as Beijing, Tianjin, Henan, obtained distinct economic, and the folk prescription bearing capacity is generally about 2 times of straight stake.The extruding-spreading device patent that also have Japanese Kubota Iron Co., Ltd. identical with this forming machine major technique feature; The northern photoelectricity in back is developed the Multifunction hydraulic extruding extender, has implemented the stake of DX multi-nodal enlarging according to this, has the Shandong Dongying City to develop the hydraulic pressure reducing club-footed pile again.It is configured with forms such as two arms or three arms.More than its structural feature of several equipment to be hydraulic pressure squeezed, basic ideas are roughly approaching.The inventor is through application in practice and analysis for many years, and there is following some deficiency in the squeezed mode of this hydraulic pressure: 1, forming machine complete machine heaviness, and the cost cost is higher; The squeezed efficient of moulding is lower, and every machine-team moulding quantity is few, and it is big to apply cost.During moulding, under many geological conditionss, soil layer is by compacted but drop after destroyed, landslide occurs and moulding is lack of standardization, size is inaccurate; Need special-purpose crane to be used simultaneously in addition, increased cost and operation easier.
Summary of the invention:
The purpose of this utility model promptly is to propose the special-purpose borehole-enlarging drilling tool of a kind of auger machine, it can be cooperated with auger machine easily carry out reaming, and have the characteristics of the fast and reaming moulding standard of reaming speed, overcome the existing above-mentioned defective of above-mentioned hydraulic pressure reaming mode and structure.
The utility model is finished the technical scheme that its invention task proposed:
Have pipe in, interior pipe is connected with the drilling rod of auger machine; The periphery of interior pipe has helical blade and have outer sleeve with its one outside helical blade;
The bow arm bite that has lifting gear and outwards go forward one by one gradually during in lifting under the lifting gear effect and in lifting;
Every pair of bow arm bite has two sharpeners, and an end of two sharpeners is hinged, and the other end is connected with the outer sleeve hinge with lifting gear respectively.
Lifting gear comprises power section, drive rod, and an end of every pair of one of them sharpener of bow arm bite is connected with the drive rod hinge.
Lifting gear also comprises the carrying soil dish of an oscilaltion under the drive rod effect, and an end of every pair of one of them sharpener of bow arm bite is connected with carrying soil dish hinge, also can be hinged with drive rod.
The power section of lifting gear is arranged in the interior pipe.
The power section of lifting gear is arranged on the top of auger machine drilling rod, drives
The middle cavities that bar passes drilling rod enters interior pipe downwards.
Bow arm bite is a pair of, and symmetrically arranged two pairs, what be uniformly distributed along the circumference is how right.
The sharpener of bow arm bite can be straight knife, curved knife, decides with stake shape.
The power section of lifting gear can be the machine power of hydraulic cylinder, cylinder or motor and reducing gear composition.
The utility model borehole-enlarging drilling tool is when work, the drill bit of auger machine drilling rod front end is taken off, the interior pipe of borehole-enlarging drilling tool is connected with drilling rod front end flange, be about to whole borehole-enlarging drilling tool and be connected the drilling rod front end, enter in the straight shape stake hole with drilling rod decline, in the location, position of giving the moulding reaming, start auger and make the drilling rod rotation, whole expansion machine drill tool rotates synchronously with drilling rod, the drive rod of lifting gear drives (also can coil by carrying soil) bow arm bite and outwards goes forward one by one gradually under the power section effect, stake hole inwall is cut, and the soil that cuts away falls in the carrying soil dish, rise to upper position by carrying soil dish at last, soil is sent outside the hole by helical blade.
The structure design that the utility model proposes has following effect:
1, its boring borehole-enlarging drilling tool makes full use of the rig partial devices, changes drill bit at any time and promptly can satisfy different demands.
2, shaping speed improves greatly, about every machine-team six roots of sensation more originally, brings up to every machine-team 20-30 root.
3, the whole operation process is simple and direct, is easy to grasp and operation, can reduce the operation number and save the native time cost of cleaning stake than original structure.
4, stake hole forming standard, accuracy is higher.
5, more original reaming forming machine can be saved facilities such as loop wheel machine.
