Vertical rotation hardening device of wind driven generator spindle

Abstract

The invention discloses a vertical rotation hardening device of a wind driven generator spindle. The device is composed of a travelling crane, a travelling crane rail, a quenching oil groove and a quenching oil circulation pump. The vertical rotation hardening device is characterized in that the bottom of the travelling crane is provided with a rotation pipe, wherein the upper end of the rotation pipe is fixed on a rotation disk driven by a motor on the travelling crane; the lower end of the rotation pipe is fixedly connected with an upper suspension clamp; the opening of the suspension clamp is clamped in an annular groove on the upper end of the wind driven generator spindle; a hanging steel wire rope is arranged in the rotation pipe; the lower end of the hanging steel wire rope is fixed on a turntable on the bottom wall of the mouth of the suspension clamp; the upper end of the hanging steel wire rope is coiled on a rotation roller; and meanwhile quenching oil is deepened. In the vertical rotation hardening device of the wind driven generator spindle, because the wind driven generator spindle vertically rotates in the quenching oil and the quenching oil is evenly sprayed to the wind driven generator spindle, a steam blanket on the surface of the wind driven generator spindle is easy to break, thereby quickening the cooling speed of the wind driven generator spindle, shortening quenching cooling time, and lowering energy consumption.

Description

[0001] technical field [0002] The present invention relates to the improvement of a large-scale shaft-type hanging quenching device, in particular to a vertical rotary quenching device for the wind-driven generator main shaft, which is specially used for rapid quenching of the wind-driven generator main shaft. Background technique [0003] At present, the quenching of the main shaft of the wind turbine is generally carried out in a horizontal quenching oil tank, and the main shaft of the wind power generator needs to be hoisted horizontally through the lifting device. Movement up and down in the quenching oil to increase the cooling rate. The lifting device includes a crane, a hoisting wire rope, a hook, and a main shaft bracket of the wind power generator. The frame is connected with the lifting device of the crane through the hook and the hoisting wire rope. Through the lifting and lowering of the crane, the main shaft of the wind turbine and the bracket of the main sha...

AI Technical Summary

Problems solved by technology

The deficiencies of this wind power generator main shaft suspension quenching device are: 1, because the wind power generator main shaft can only do lifting motion in the quenching oil, can not rotate, and the wind power generator main shaft bracket has occupied the surface area of ​​the wind power generator main shaft , the steam film on the surface of the main shaft of the wind turbine is not easy to break, which affects the cooling speed and uniformity of the main shaft of the wind turbine; Tons, and relatively heavy, in a hot state, it is easy to bend the shaft when placed horizontally, which increases the amount of turning and reduces labor efficiency; 3. The main shaft of the wind turbine is raised and lowered by the lifting device of the crane. The main shaft is heavier, which increases the power to overcome the potential energy when lifting, so the energy consumption is larger
