Problems solved by technology

[0002] At present, in domestic coal mining, the protection of drill pipes is very important. The drill pipes have been in work for a long time, and the improper protection will reduce the work efficiency. Now there are many methods and ways to prevent metal corrosion. On a metal or alloy, or apply anti-corrosion paint on the metal surface, but this is not practical for large equipment or long equipment like drill pipes

Embodiment Construction

[0012] The present invention is further described below in conjunction with accompanying drawing.

[0013] Such as figure 1 As shown, a mining drill pipe anti-corrosion device includes a casing 2 and a drill body 1. It is characterized in that the casing 2 is connected to the drill body 1, and the casing 2 is provided with an oil storage device 3, and the oil storage device 3 is outside A ring brush 4 is provided, and a ring scraper 5 is provided at the front end of the housing 2 .

[0014] The ring scraper 5 matches the diameter of the drill rod.

[0015] The oil reservoir 3 is connected to the ring brush 5 through the solenoid valve 6 .

[0016] The working principle of the present invention is:

[0017] The present invention makes the solenoid valve 6 control the amount of oil through the expansion and contraction of the drill pipe, the ring scraper 5 can take out the coal cinder brought out by the drill pipe, and the ring brush 4 can oil the drill pipe.

Abstract

A mining drilling rod anti-corrosion apparatus comprises a housing and a drilling body. The mining drilling rod anti-corrosion apparatus is characterized in that the housing is connected with the drilling body; an oil storage device is disposed in the housing; outside the oil storage device is provided with an annular brush; the front end of the housing is provided with an annular scrape; with telescopic actions of the drilling rod, oil amount can be controlled via a solenoid valve; coal slag brought out by the drilling rod can be taken out by the annular scrape; and the drilling rod can be oiled via the annular brush. The mining drilling rod ant-corrosion apparatus is simply structured and has convenient use; and service life of the drilling rod can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of coal mine drill pipes, and in particular relates to an anticorrosion device for mine drill pipes. Background technique [0002] At present, in domestic coal mining, the protection of drill pipes is very important. The drill pipes have been in work for a long time, and the improper protection will reduce the work efficiency. Now there are many methods and ways to prevent metal corrosion. Putting on a metal or alloy, or applying anti-corrosion paint on the metal surface, but this is not practical for large equipment or long equipment like drill pipes. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide an anti-corrosion device for drill pipes used in mines, which protects the drill pipes every time it is stretched, has a simple structure, is easy to use, and is suitable for use in mines. [0004] For ...
