Lubricating device of drill rod

Abstract

The invention relates to a lubricating device of a drill rod. The lubricating device of the drill rod is characterized by comprising an adjusting compass, a fixing ring, an adjusting core, a piston, a piston barrel, an upper cylinder barrel, an upper connecting ring, a thread dope outlet, a lower connecting ring, a lower cylinder barrel, a blocking plate, steel balls and oil channels, wherein the lubricating device comprises the upper cylinder barrel and the lower cylinder barrel; the lower end of the upper cylinder barrel is connected with the lower cylinder barrel through the upper connecting ring and the lower connecting ring; the thread dope outlet is formed in one side of the upper connecting ring; the piston barrel penetrates through the upper cylinder barrel and the lower cylinder barrel; the piston is arranged at the upper end of the piston barrel; the adjusting core is connected to the piston to be connected with the adjusting compass; the fixing ring is arranged between the upper cylinder barrel and the adjusting core; the blocking plate with a through hole is arranged in a position under the piston barrel in the lower cylinder barrel; a plurality of oil channels are formed in the lower end of the lower cylinder barrel; and each steel ball is arranged at the upper end of the corresponding oil channel. The lubricating device of the drill rod disclosed by the invention has the advantages of being convenient to use and quick and uniform in oil injection, the time is saved, the working efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a lubricating device for a horizontal directional drilling machine, in particular to a lubricating device for a drill rod. Background technique [0002] Now, when the two drill pipes of the horizontal directional drilling rig are connected, it is necessary to add thread oil to lubricate the threaded connection part of the two drill pipes, which is convenient for loading and unloading. Now the thread oil is manually applied to the threaded part of the drill pipe. This was time-consuming and inconvenient. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide a lubricating device for drill rods. [0004] The invention provides a lubricating device for drill rods, which is characterized in that the lubricating device for drill rods includes an adjusting compass (1), a fixed ring (2), an adjusting core (3), a piston (4), and a piston barrel (5), upper cylinder...
