Multi-freedom-degree drill rod lubricating oscillation rod

Abstract

The invention discloses a multi-freedom-degree drill rod lubricating oscillation rod. The oscillation rod comprises a supporting pipe, a rotating shaft, an oil pumping nozzle connecting base and an oil pumping nozzle. A plurality of oil spraying holes uniformly distributed in the width and height direction of the oil pumping nozzle are formed in the oil pumping nozzle. The oil pumping nozzle is detachably installed at the front end of the oil pumping nozzle connecting base. An oil injection hole for being connected with an oil injection pipe and a communicating cavity communicated with the oil injection hole are formed in the oil pumping nozzle connecting base. The oil injection hole is communicated with all the oil spraying holes through the communicating cavity. A fixing groove A is formed in the rear end of the oil pumping nozzle connecting base. The front end of the rotating shaft is connected to the fixing groove A in a sleeved mode. The rotating shaft and the fixing groove A can relatively move in the radial direction and constrain the motion stroke through a limiting plug pin. The rear end of the rotating shaft is fixed to the front end of the supporting pipe. The rotating shaft can rotate in the axial direction. An outer ring of the rotating shaft is sleeved with a spring. Lubricating butter is smeared more uniformly, and when the external resistance is excessively large, the rotating shaft can drive the oil pumping nozzle to rotate, and the self-protection effect is achieved.

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...

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
