Super-large-aperture pile foundation hole drilling machine

Abstract

The invention relates to a super-large-aperture pile foundation hole drilling machine. The super-large-aperture pile foundation hole drilling machine comprises a track rack, a rotary bracket, a drilling machine and a blower, wherein a drilling disc is arranged at the lower part of the drilling machine, drilling heads are distributed on the drilling disc, a drilling shaft is upward arranged at the middle part of the drilling disc, an input gear is sleeved on the drilling shaft, a speed regulating motor is fixed on the rotary bracket, a rotor shaft of the speed regulating motor is connected with a driving gear, the driving gear, the input gear and a bridging gear are sequentially meshed with one another so as to be in transmission, the bridging gear is coaxially connected with a traveling gear, the traveling gear is meshed with the track rack, a suction head is arranged at the lower part of the blower, the lower part of the suction head is connected with slide wanes, a wind power chamber and a wind power transmission pipe are upward arranged at the upper part of the suction head, and a wind wheel is arranged in the wind power chamber. According to the super-large-aperture pile foundation hole drilling machine, super-large apertures can be formed in one step through drilling, and driven-in pile foundations are firm and are difficultly damaged; and the hole drilling efficiency is high, and the cost is low, so that the super-large-aperture pile foundation hole drilling machine is applicable to large-scale popularization and use.

Description

Technical field [0001] The present invention involves a pile foundation drilling machine, especially for large -scale pile -based drilling machines suitable for large pile foundation projects. Background technique [0002] At present, before the construction of houses, high towers or bridges, the foundation needs to be built, and the existing pile foundation drilling machine can be drilled with a small pore diameter and the efficiency is not high.The existing pile foundation drilling machine has a complex structure and high cost, which is not convenient to use. Invention content [0003] In order to overcome the problem of existing pile foundation drilling machines that cannot drill large pores, the present invention provides a super -large -pore pile foundation drilling machine.The pile foundation is not easy to break, and the drilling efficiency is high, the cost is low, which is suitable for large -scale popularization. [0004] The technical solution used to solve its techni...
