Semi-automatic blade grinding method and device

Abstract

The invention discloses a semi-automatic blade grinding method. The two sides of a blade are ground, and the two-side grinding comprises the following steps that S1, the blade is fixed, and a grinding head is parallel to the blade; S2, the grinding head performs grinding from the top to the bottom, and first-time grinding is completed; S3, the grinding head is moved to be staggered from first-time grinding; S4, the grinding head performs grinding from the bottom to the top, and second-time grinding is completed; S5, the grinding head is moved to be staggered from second-time grinding; and S6, the steps S2-S5 are repeated till the parts are close to the leaf tips. The invention further discloses a semi-automatic blade grinding device. The semi-automatic blade grinding device comprises a grinding device body and a dust collection device. By means of the semi-automatic blade grinding method, the grinding operation efficiency is improved, the station occupation time is shortened, the number of grinding workers is reduced, and the labor cost is reduced; high-place operation of workers is avoided, and the safety risk of falling is eliminated; and dust caused by grinding in a workshop can be greatly reduced, investment of related environment-friendly equipment is avoided, operation is convenient, safe and labor-saving, and meanwhile the blade production period is shortened.

Description

technical field [0001] The invention relates to a semi-automatic blade grinding method and device. Background technique [0002] Before painting wind turbine blades, the surface needs to be polished to a bright surface. There are strict requirements on the degree of polishing. If the polishing is not in place and there is a bright surface, it will affect the subsequent paint, and even cause the problem of paint peeling off in the wind field. The traditional grinding is all done by personnel, and the grinding time is relatively long. Due to the new and old employees, each grinding ability is different, and there is a danger of working at heights. Therefore, in order to ensure that the blade has no bright surface, greatly reduce the grinding time, and avoid the danger of employees working at heights, it is necessary to develop a semi-automatic blade grinding method and equipment.
