Intelligent oiling device with externally-hung overhead crane

Abstract

The invention relates to an intelligent oiling device with an externally-hung overhead crane. The device comprises a lubricating pump, an oil storage tank, a distribution device and a controller, wherein the lubricating pump is horizontally arranged below the oil storage tank and is connected with the oil storage tank; an oil outlet of the oil storage tank communicates with the distribution device through a pipeline; a heat preservation sleeve is arranged on the pipeline, and the heat preservation sleeve comprises a pipe body, an electric heating wire and a photovoltaic panel; the photovoltaic panel is connected with the electric heating wire through an external photoelectric transducer; a grease filter is arranged between the outlet of the oil storage tank and the inlet of the distribution device; the oil storage tank is externally connected with an inert gas cylinder; the inert gas cylinder and the oil storage tank pass through a balance pipe; an automatic valve is arranged on the balance pipe; and an in-tank pressure sensor is arranged on the oil storage tank and is electrically connected with the automatic valve. The oiling device ensures the stability of lubricating oil adding in a sealed state and is not prone to deterioration in a severe environment, the lubricating oil can be automatically added in a fixed-time, fixed-point and quantitative manner, lubrication is reliable, abrasion of parts is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to an external-mounted refueling device for an intelligent crane. Background technique [0002] With the development of the economy and the acceleration of the industrialization process, the gradual replacement of labor by mechanical automation is a major trend of scientific and technological progress. In order to meet the lubrication requirements of mechanical equipment, it is necessary to carry out regular, fixed-point and quantitative centralized lubrication of mechanical equipment to reduce wear and tear of components, improve work efficiency, reduce the realization and damage of mechanical equipment parts due to poor lubrication, and extend equipment service life.

Problems solved by technology

[0003] In the prior art, lubricating oil is usually manually added to the corresponding mechanical equipment on a regular basis. The manual refueling method requires manual preparation of the corresponding lubricating oil in advance. Waste or too little preparation needs to adjust the cycle of adding lubricating oil next time, which increases the inconvenience of adding lubricating oil

The lubricating oil is stored in the mechanical equipment in advance for the addition of lubricating oil, but because the mechanical equipment is placed in different areas, especially in plateau areas such as Xinjiang and in severe cold areas such as the Arctic, the environment is relatively harsh, and the lubricating oil due to low temperature, Under the influence of high humidity environment, the viscosity of lubricating oil will usually increase, solidify or even deteriorate, which will affect the lubrication effect; in addition, when the refueling device is pumped out by an electric motor, there will be air bubbles in the oil, which will affect the effect of adding lubricating oil

Due to the negative pressure state of the closed oiling device, when the pressure is unbalanced to a certain condition, the oil well pump is easy to idle, which not only affects the delivery of lubricating oil, but also brings loss to the oil well pump, and the service life of the oil well is low
