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 invention relates to a pile foundation drilling machine, in particular to a pile foundation drilling machine with a super large aperture suitable for large pile foundation engineering. Background technique

[0002] At present, it is known that pile foundations need to be built before building houses, towers or bridges, and the existing pile foundation drilling machines can drill very small holes, which are not efficient and cannot meet the requirements of large-scale construction projects. In addition, The existing pile foundation drilling machine has complex structure, high cost, and is not easy to popularize and use. Contents of the invention

[0003] In order to overcome the problem that the existing pile foundation drilling machine cannot drill larger apertures, the present invention provides a pile foundation drilling machine with super large aperture. The inserted pile foundation is firm and not easy to break, and the drilling efficiency i...
