Preferably, the oil discharge pipe comprises a vertical pipe and an inclined guide pipe, the vertical pipe penetrates through the top wall of the gear box body, the guide pipe is located in the gear box body, the vertical distance between the tail end of the guide pipe and the top wall of the gear box body is the largest, and oil flowing holes are uniformly formed in one side below the guide pipe.

Preferably, the end of the draft tube is closed.

Preferably, a level sensor is arranged inside the oil storage box.

Preferably, an alarm is arranged outside the oil storage box and is in signal connection with the level sensor.

Preferably, the top of the oil storage box is provided with an oil filling port, and the oil filling port is in threaded connection with a screw cap.

The utility model has the following beneficial effects:

when the gear box starts to work, lubricating oil in the oil storage box flows into the oil discharge pipeline through the flow control valve, the flow control valve controls the flow rate of the lubricating oil so that the lubricating oil can flow out controllably and continuously without waste, the lubricating oil is discharged right above the speed change gear set by the oil discharge pipeline to complete lubrication, the dripping of the lubricating oil is controlled, the internal gear of the gear box is ensured to be in a lubricating state, the possibility of the fault of the gear box is reduced, and the working stability of an elevator is improved;

secondly, the inclined guide pipe guides the lubricating oil to flow, and the lubricating oil drops through the oil flow hole, so that the distribution uniformity of the lubricating oil is improved, and the lubricating effect is improved;

thirdly, the material level sensor detects the level of the lubricating oil in the oil storage box, and when the level is too low, the material level sensor sends a signal to a worker; through setting up the alarm with level sensor signal connection, when the liquid level was low excessively, the alarm sent out the police dispatch newspaper, and the staff is reminded to swiftly more.
