Oiling device for lubricating portal crane

Abstract

The invention discloses an oiling device for lubricating a portal crane. An oiling device is driven by a driving device to move, and automatic oiling is achieved. A first rotating shaft and a second rotating shaft do linear motion in the X direction, so that teeth needing to be lubricated abut against a first oiling layer and a second oiling layer. Rotation is normally transmitted to a first rotating shaft and a second rotating shaft through a first universal joint and a second universal joint. Oil is supplied to the oiling device through the oil supply device, so that the problem of different grease adding amounts caused by different personal operation methods is solved; quantitative lubricating oil is provided for the teeth needing to be lubricated through an oil tank and an electromagnetic valve; the lubricating oil in the rotating shafts is scraped out through an oil scraping assembly, the lubricating oil is discharged through first oiling holes and second oiling holes, and the lubricating oil is prevented from being accumulated in the rotating shafts; and a first oil scraping rod, a third oil scraping rod, a fifth oil scraping rod, a second oil scraping rod, a fourth oil scraping rod and a fifth oil scraping rod form two sets of crank sliding block structures, so that certain residence time of a scraping plate after each stroke is finished is ensured.

Description

technical field [0001] The invention specifically relates to an oiler for lubricating a door machine. Background technique [0002] The gantry crane is a gantry crane, also referred to as a gantry crane or a gantry crane for short. It is one of the jib cranes that are driven by electricity and run on rails. Its structure includes an upper rotating part and a lower running part. The upper rotating part is installed on a door frame and can be rotated freely by 360° relative to the lower running part. The gantry can move along the track, and at the same time it is the load-bearing part of the crane. The self-weight and hoisting weight of the crane are both borne by the gantry and transmitted to the ground track by it. [0003] The open gear of the door operator is the core bearing part of the door operator, and the lubrication effect directly affects the operation status and service life of the door operator. At present, the lubrication of the open gears of the door machine m...

AI Technical Summary

Problems solved by technology

At present, the lubrication of the open gears of the door machine mainly relies on manual grease lubrication, but this oiling method has the following problems: First, due to the difference in personal operation methods, the amount of grease added will be different. Once too much or too little, it will cause It causes uneven application of grease or leakage of grease, resulting in no grease lubrication in some parts; second, manual application of grease is time-consuming and laborious, requiring high-altitude operations, which poses a safety hazard
