Problems solved by technology

The traditional mud scraping method is that each of the internal and external fitters holds a mud scraper made of a rubber ring to carry out the mud scraping operation, which requires a lot of labor and poor mud scraping effect
Another mud scraping method is the pneumatic mud scraper that comes with the automatic slips. The mud scraping effect is better, but there are problems of cumbersome installation and disassembly and high cost, and it cannot be realized for the mud brought out by the drilling tool from the big and small holes. scrape mud

Embodiment 1

[0026] refer to figure 1 , is a structural schematic diagram of Embodiment 1 of the present invention, a hand-held pneumatic mud scraping device, including a main body 2, one end of the main body 2 is a handle part 1, the other end of the main body 2 is a pneumatic mud scraping part, and the pneumatic scraper on the main body 2 The mud part is a spiral structure formed by setting the other end of the body 2 itself, and the other end of the body 2 is located on the top of the spiral structure. The handle part 1 at one end of the body 2 is connected to the gas source pipeline 4. The body 2 of the spiral structure Air blowing holes 6 are arranged on it.

[0027] In actual use: Hold the handle part 1 at one end of the body 2, and connect the spiral structure formed by the other end of the body 2 to the drilling tool to be scraped. The air blowing hole 6 set on the body 2 of the shape structure is used to scrape mud for the drilling tool to be scraped. The pneumatic mud scraping d...

Embodiment 2

[0029] Compared with Embodiment 1, the difference of this embodiment is that: the main body 2 is a pipeline of metal structure, and one end of the pipeline body 2 of metal structure is set into a pneumatic mud scraper in a spiral structure through its own deformation, and the spiral The helical surface of the pneumatic mud scraper with the shape structure is a 360-degree circle.

[0030] In actual use: the main body 2 is a pipeline with a metal structure, and the pipeline of the metal structure adopts a metal pipeline that is easily deformed. Through deformation, one end of the main body 2 is set into a spiral structure through its own deformation, forming a pneumatic mud scraper, so that the spiral structure The helical surface of the pneumatic mud scraping part is a 360-degree circle, and the diameter of the circular pneumatic mud scraping part helical surface is larger than the diameter of the drilling tool to be scraped, and the drilling tool to be scraped is on the helical...

Embodiment 3

[0032] Compared with Embodiment 2, the difference of this embodiment is that: the body 2 is also connected with a support frame along the outside of the body 2 itself, and the support frame is detachably connected with the body 2 .

[0033] In actual use: the body 2 is connected with a support frame along the outside of the body 2 itself, and the support frame is detachably connected to the body 2, because the body 2 is a metal structure pipeline that is easily damaged during the mud scraping process, so setting the support frame increases the overall Service life of pneumatic mud scraper.

Abstract

The invention relates to the technical field of engineering machinery, in particular to a handheld pneumatic sludge scraping device and a using method thereof. One end of a body is held by hand, and ahelical structure formed by arranging the other end of the body is sleeved with a drilling tool to be scraped; and then, after an air source pipeline is ventilated, airflow passes through blow holesformed in the body of the helical structure for scraping the drilling tool to be scraped. According to the pneumatic sludge scraping device of this structure, the drilling tool for a wellhead and large and small rat holes can be scraped safely and conveniently, and meanwhile operators can be reduced by one; and the drilling tool for the wellhead and the large and small rat holes are purged and scraped cleanly and thoroughly, and the structure is simple; and the sludge scraping efficiency is high.

Description

[0001] Technical field [0002] The invention relates to the technical field of engineering machinery, in particular to a hand-held pneumatic mud scraping device and a method for using the same. Background technique [0003] During the production process of the drilling industry, it is necessary to take the drilling tool out of the well or the mouse hole and scrape off the mud adhering to the surface of the drilling tool to prevent the mud from contaminating the drilling floor and causing the risk of slipping and falling. The traditional way of scraping mud is that each of the internal and external fitters holds a mud scraper made of a rubber ring to carry out the mud scraping operation, which requires a lot of labor and poor mud scraping effect. Another mud scraping method is the pneumatic mud scraper that comes with the automatic slips. The mud scraping effect is better, but there are problems of cumbersome installation and disassembly and high cost, and it cannot be realize...
