An Improved Long Spiral Drilling Rig

Abstract

The invention discloses an improved long spiral drilling machine which comprises a machine body, a power head, a mud scraping device, a running device, a power device and a hydraulic system, wherein the power head is connected with a drill rod and is used for driving the drill rod to rotate around the axis of the drill rod, and a drill bit is arranged at one end of the drill rod. The improved long spiral drilling machine also comprises an upright column, wherein a retaining cylinder is installed on the upright column, and one side of the retaining cylinder is provided with the mud scraping device for clearing the drill rod and / or the drill bit. Therefore, the improved long spiral drilling machine provided by the invention is simple in structure, firm and reliable, esthetic in appearance, flexible in use, convenient to use, maintain and repair, high in machine transferring efficiency, and capable of greatly relieving the labor intensity of workers, increasing the production efficiency and saving the production cost; the improved long spiral drilling machine is simple and convenient to disassemble and assemble, and a main frame can be arranged on a flat car through a chassis system of the main frame, thereby greatly shortening the machine transferring time and reducing the transferring workload; and meanwhile, adhesives on the drill bit and the drill rod can be removed in real time, thereby improving the operation quality and increasing the operation speed.

Description

technical field [0001] The invention belongs to engineering machinery, in particular to an improved 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 constructi...

AI Technical Summary

Problems solved by technology

Although the auger drill has improved the structure of the drill pipe and the drill bit, it cannot solve the problem of removing the adhesions on the drill bit and the drill pipe during operation, and at the same time cannot walk, move the machine, and align the pile quickly and conveniently. Therefore, it is urgently needed Improved Design
