Abstract

The invention relates to the technical field of telescopic arms, and discloses a telescopic arm lubricating and oil accumulation preventing device. The device comprises an outer arm, a protruding block is fixedly installed on the inner wall of the outer arm, an inner arm is slidably connected into the outer arm, an ejector block is slidably connected to the surface of the inner arm, a dielectric substance is fixedly installed at the front end of the ejector block, an ejector rod is fixedly installed outside the ejector block, electrode plates are fixedly installed on the left side and the right side of the ejector rod, an electromagnet is fixedly installed at the end, away from the outer arm, of the ejector rod, and spring rods are fixedly installed on the left side and the right side of the end, away from the outer arm, of the ejector rod. According to the telescopic arm lubricating and oil accumulation preventing device, when the telescopic arm works, atomized oil is automatically sprayed to the interior of the telescopic arm, the spraying area is wide, spraying is uniform, when too much oil is accumulated in the telescopic arm, the internal oil is sucked into an oil cavity to complete circulation, the lubricating oil can be repeatedly used, and resources are greatly saved.

Description

technical field [0001] The invention relates to the technical field of telescopic arms, in particular to a device for lubricating and preventing oil accumulation for a telescopic arm. Background technique [0002] The telescopic arm is one of the most frequent parts of the excavator during use. The telescopic arm needs to be continuously added lubricating oil during long-term work to prevent excessive friction between the various parts and reduce the service life of the mechanical parts. However, manually add lubricating oil The lubricating oil is very cumbersome, and the lubricating oil will accumulate in the connection after adding, the oil will absorb dust, and most of the oil will gradually drip and cause waste. [0003] In order to solve the above problems, the inventor provides a device for lubricating and preventing oil accumulation of the telescopic arm. When the telescopic arm is working, it automatically sprays mist oil on the inside. The spraying area is wider and...
