Abstract

The invention discloses a long-spiral drilling machine. The long-spiral drilling machine comprises a machine body, a power head, a mud-scraping device, a walking device and a power device. The power device is connected with a drilling rod and used for driving the drilling rod to rotate around the axis thereof. One end of the drilling rod is provided with a drill bit. The long-spiral drilling machine further comprises a column, on which a protection cylinder is arranged. One side of the protection cylinder is provided with the mud-scraping device used for cleaning the drilling rod / or the drill bit. The long-spiral drilling machine has following beneficial effects: the long-spiral drilling machine is simple in structure, firm and reliable and is attractive in appearance and used flexibly; application, maintenance and repair are conducted conveniently; machine moving efficiency is high and labor intensity of workers is greatly reduced; production efficiency is improved and production cost is saved; assembly and disassembly are easy and convenient; the main machine can be loaded on a flat car by utilizing a chassis system so that time spent on transferring the machine is greatly shortened and transfer workload is reduced; and adhesions of the drill bit and the drilling rod can be eliminated in a real-time mode so that work quality and speed are improved.

Description

technical field

[0001] The invention belongs to engineering machinery, in particular to a long auger drilling machine. Background technique

[0002] The most commonly used pile foundation construction equipment is mainly the screw pile machine. The reason is that it has the advantages of simple operation, convenient use, and high drilling efficiency. Influenced by other factors, it only has a narrow construction scope and cannot implement rock formation drilling. Today, buildings are constantly developing in terms of height and space, and they are also facing challenges from various geological conditions in the region, especially highways, viaducts, high-speed railways, etc. Their construction is particularly dependent on more solid pile foundations. At present, these The foundation construction of the building still uses equipment such as rotary drilling, impact drilling or positive and negative circulation drilling rigs to complete the pile foundation construction of larg...
