Abstract
The invention discloses a lower fixed key slot sliding power plate for a piling pore-forming drill. The power plate comprises a working turntable and a core cylinder, wherein the working turntable is driven by a power input shaft; the core cylinder vertically penetrates a hole of the working turntable and is fixedly connected with the working turntable through a connecting component; and a helical drill rod is arranged inside the core cylinder and in sliding fit connection with the inner wall of the core cylinder through a key and a key slot. The power plate has the advantages of fulfilling the aim of improving the stability and safety of the piling pore-forming drill and reducing the manufacturing cost and power consumption during drilling by lowering the installation position of a driving and speed-shifting mechanism of the piling pore-forming drill. The core cylinder and the helical drill rod inside the core cylinder vertically penetrate the hole of the working turntable, so that the working turntable serving as the driving and speed-shifting mechanism of the helical drill rod can be arranged at a lower position corresponding to the ground, the working stability and the safety of the piling pore-forming drill are greatly improved, the requirement on a pile strength is reduced and the manufacturing cost of the piling pore-forming drill is saved.
Description
Technical field
The present invention relates to piling pore-forming drill, especially relate to the lower fixed key slot sliding power plate that is used for piling pore-forming drill.
Background technology
At present, the driving of piling pore-forming drill, gear are arranged on the top of drilling rod more.This just makes the less stable of boring tower, give boring tower installation, move and cause difficulty, even cause turning over the generation of tower accident.Because drive, the gear quality is bigger, height is at the piling pore-forming machine more than 20 meters, it drives, the weight of gear is more than five tons, this just requires the intensity of king-tower foot piece to want high, has therefore also improved the manufacturing cost of piling pore-forming drill.
Summary of the invention
The object of the invention is to provide a kind of lower fixed key slot sliding power plate that is used for piling pore-forming drill, reaches to improve piling pore-forming drill stability, reduction manufacturing cost and power consumption.
For achieving the above object, the present invention can take following technical proposals:
The lower fixed key slot sliding power plate that is used for piling pore-forming drill of the present invention, it comprises the working rotary table that is driven by power input shaft, vertically run through the core tube that described working rotary table dish hole is provided with up and down, described core tube and working rotary table are fixedly connected by link; Be provided with auger stem in the core tube, described auger stem is slidingly matched by key and keyway with core tube inwall and connects.
Described keyway is opened on the described auger stem vertically; Described key is fixedly installed on the described core tube inwall vertically.
Described working rotary table is by dish shell, upper and lower disk cover and be arranged on the interior mandrel of dish shell, be fixed on the arc gear ring on the mandrel, and is arranged on the arc gear wheel formation that is meshed with described arc gear ring on the power input shaft.
The cross section of described key is semicircle, or circular arc, rectangle shape, triangle; The corresponding with it keyway cross section that is slidingly matched is a half slot, or arc groove, rectangular channel, vee gutter.
Described working rotary table also can be arranged to other structure such as gear ring structure etc., and the distortion of its structure all belongs to protection scope of the present invention.
The invention has the advantages that driving, the gear installation site of realizing reducing piling pore-forming drill, thereby reach stability and the safety that improves piling pore-forming drill, the power consumption purpose when reducing manufacturing cost and probing.During work, the present invention is installed on the pile frame, the power of power source output drives the working rotary table rotation by described power input shaft, and working rotary table drives described core tube and rotates, and the core tube drives auger stem boring with rotation torque by key connecting.Because the auger stem of core tube and interior setting thereof vertically runs through working rotary table dish hole, therefore working rotary table gets final product mounting distance ground lower position as the driving gear of auger stem, and the driving gear that has solved existing drilling rod must be installed in the deficiency on drilling rod top.The job stability and the safety of piling pore-forming drill have been improved greatly.Also greatly reduce simultaneously requirement, the manufacturing cost of having saved piling pore-forming drill to pile frame strength.
