Efficient oil change device for wind power gear box

Abstract

The invention discloses an efficient oil change device for a wind power gear box. The efficient oil change device comprises a base, a lubricating oil box, a waste oil box, a lubricating oil conveying pump, a vacuum pump, a cooling water tank, an electric control box, a wind power tower barrel gear box, a wind power tower barrel, a control system and an air compressor. The waste oil box and the lubricating oil box are both internally provided with a liquid level meter, an electric heater and a temperature sensor. The wind power tower barrel gear box is connected to the lubricating oil box through a lubricating oil conveying hose, and the wind power tower barrel gearbox is connected to the waste oil box through a waste oil output hose. According to the device, lubricating oil is heated by the electric heater in the lubricating oil box, the viscosity of the lubricating oil is reduced, the conveying rate is increased, the operation of pumping out waste oil and adding new oil can be completed on the ground or an operation and maintenance ship only by connecting an oil inlet and outlet hose to an oil box connector of the wind power gear box, aerial work is reduced, up-and-down oil drum transfer is avoided, therefore, work safety is greatly improved, and the work intensity of maintenance staff is reduced.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a high-efficiency oil change device for a wind power gearbox. Background technique [0002] The gearbox in the wind turbine is an important mechanical component. Its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it obtain corresponding power. At present, the vertical distance between the gearbox of the wind power tower and the bottom of the maintenance ladder is about 100 meters (some have to be transferred to the platform). The conventional oil change method is to manually send the oil into the tower, and lift the oil drum to the vicinity of the gearbox by the elevator inside the tower. , Manually extract the waste oil and then add new oil, the operation is complicated, and it takes about three days to replace the oil of a wind power gearbox, the labor intensity is high, the oil change efficiency is ...
