Automatic drill rod cleaning device

Abstract

The invention relates to an automatic drill rod cleaning device. The automatic drill rod cleaning device comprises a cleaning tank body and a cleaning mechanism, wherein switchable drill rod through holes are formed in the lower part of the cleaning tank body; drill rods penetrate through the cleaning tank body; the cleaning mechanism comprises a gas storage tank, a sand storage tank and a sand blasting tank; the gas storage tank is connected with the sand blasting tank through a high-pressure gas pipe; the sand storage tank is arranged at one side of the sand blasting tank and is connected with the sand blasting tank through a sand inlet flexible pipe; the cleaning mechanism is connected to the side wall of the cleaning tank body; first spray heads and second spray heads are arranged on the side walls of the cleaning tank body; the first spray heads are connected with the gas storage tank through high-pressure gas pipes; the second spray heads are connected with the sand blasting tankthrough pipelines. Compared with the prior art, the automatic drill rod cleaning device disclosed by the invention can be used for automatically cleaning the drill rods, the working efficiency is increased, and the labor cost is reduced; a cleaning process is carried out in a sealed tank body, and is environmentally friendly and pollution-free; by adopting a cleaning way that high-speed air flowis combined with a sand blasting process, the purpose of cleaning the drill rods and drill bits can be rapidly achieved.

Description

Technical field [0001] The invention belongs to the technical field of building foundation construction, and specifically relates to an automatic cleaning device for drill rods. Background technique [0002] Foundation pit engineering refers to the supporting structure, dewatering, earthwork excavation and backfilling adopted to ensure the construction of the foundation pit, the safety of the main underground structure and the surrounding environment from damage, including survey, design, construction, monitoring and inspection, etc. It is a foundation pit project. Foundation pit engineering is a systematic engineering integrating geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology, including engineering survey, supporting structure design and construction, earth excavation and backfilling, groundwater control, information construction and surrounding areas Environmental protection, etc. The simplest and most economical m...

AI Technical Summary

Problems solved by technology

During the foundation pit construction, when the drill pipe and other construction equipment repeatedly mix the cement and soil, the cutter head will usually bring out and stick a lot of cement and soil slurry. If they are not cleaned, the efficiency of the equipment construction process will be reduced and the construction quality will be affected.

These cement muds are generally firmly adhered to the drill bit and are extremely difficult to remove. At present, manual processing with a spatula is required.

At the same time, in order to ensure the dilution of the cement slurry in the construction pile, the high-pressure water gun is generally not used for flushing, and the high-pressure water gun cannot remove the dried and solidified cement slurry
