A multi-degree-of-freedom drill pipe lubricating swinging rod

Abstract

The invention discloses a multi-degree-of-freedom drilling rod lubricating swing rod, which includes a support pipe, a rotating shaft, a nozzle seat and a nozzle, and the nozzle is provided with a number of nozzle holes evenly distributed in the width and height directions of the nozzle The oil nozzle is detachably installed on the front end of the oil nozzle socket, and the oil nozzle socket is provided with an oil injection hole for connecting the oil injection pipe and a communication cavity connected with the oil injection hole, and the oil injection hole is connected with all the oil injection holes through the communication cavity. The hole is connected; the rear end of the nozzle socket is provided with a fixed groove A, and the front end of the rotating shaft is sleeved in the fixed groove A. The rotating shaft and the fixed groove A can move relative to each other in the radial direction, and the movement stroke is restricted by the limit pin ; The rear end of the rotating shaft is fixed on the front end of the support tube, the rotating shaft can rotate axially, and the outer ring of the rotating shaft is covered with a spring. The invention spreads lubricating butter more evenly, and when the external resistance is too large, the rotating shaft can drive the grease nozzle to rotate, so as to play the role of self-protection.

Description

technical field [0001] The invention relates to a device for lubricating drill rods of mine drilling equipment, in particular to a multi-degree-of-freedom drill rod lubricating swing rod. Background technique [0002] The drill pipe thread of the engineering drilling rig is socketed on the trolley. When loading and unloading the drill pipe, in order to facilitate disassembly and protect the connecting thread of the drill pipe, it is necessary to apply butter to the thread connection. There are following deficiencies in the existing drilling rod lubricating device: 1. The lubricating device (hereinafter referred to as the lubricating device) used to apply lubricating butter for the drilling rod is usually a rigid structure, which is easy to deviate from the set position when encountering external resistance, so that The joint with the drill pipe is not enough, and the lubrication is uneven; 2. The lubricating device is usually a rigid structure. When the external resistance i...

Problems solved by technology

There are following deficiencies in the existing drilling rod lubricating device: 1. The lubricating device (hereinafter referred to as the lubricating device) used to apply lubricating butter for the drilling rod is usually a rigid structure, which is easy to deviate from the set position when encountering external resistance, so that The joint with the drill pipe is not enough, and the lubrication is uneven; 2. The lubricating device is usually a rigid structure. When the external resistance is too large, it will be damaged or deformed; 3. The oil nozzle of the lubricating device is attached to the drill pipe, and the drill When the rod is loaded and unloaded, it will move in the vertical direction, so that the fitting surface between the oil nipple and the drill pipe is easy to wear, resulting in insufficient fit between it and the drill pipe
