Fastening mechanism for automatic painting device of wind power tower drum

Abstract

A fastening mechanism for an automatic painting device of a wind power tower drum comprises a fixed seat and a movable clamping strip; the movable clamping strip is detachably connected with the fixedseat; an arc-shaped notch is formed in the fixed seat; the movable clamping strip is arc-shaped, and the radian of the movable clamping strip is matched with that of the arc-shaped notch in the fixedseat; and the movable clamping strip is provided with a screw and a screw hole, the axial direction of the screw hole is perpendicular to the arc surface of the movable clamping strip, the screw is matched with the screw hole, and the length of the portion, embedded into the inner surface side of the movable clamping strip, of the screw is adjusted by rotating the screw. The fastening mechanism can better adapt to tower drums to be clamped with different diameters by changing the connecting or mounting positions of all the components, the problem of frequent replacement of clamping pieces isavoided, and the fastening mechanism is high in universality, simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of wind power equipment manufacturing, in particular to a fastening mechanism for an automatic painting device for a wind power tower tube. Background technique [0002] Wind turbines are devices that convert wind energy into electrical energy. Wind turbines generally include wind rotor blades, generators, gearboxes, main shafts, and the main control system of wind turbines. The main control system of wind turbines includes tower base cabinets (also known as towers) Tube cabinets, tower bottom cabinets, etc.), engine room cabinets, pitch control systems, converters, control and monitoring parts of generators, electrical parts of gearboxes, etc. When the wind energy passes through the blades of the wind rotor, the blades are driven to rotate, and the rotation of the blades drives the main shaft to rotate. The main shaft rotates to input power into the gearbox. At present, as a representative product in the f...

Problems solved by technology

Wind power towers, as the basic components for installing wind power equipment, play an important role in supporting the entire equipment. Wind power towers are generally made of steel materials and installed outdoors, which are easily eroded by sunlight or rain. Therefore, in the tower During the production process, it is necessary to coat a layer of paint on the surface of the tower tube to prevent rust and corrosion on the outer surface of the tower tube. At present, there are manual painting methods and mechanical painting methods, and the efficiency of manual painting is low. Therefore, mechanical automatic painting is the development trend

Existing automatic painting devices generally include a fastening mechanism and a spraying mechanism, but the principle of the fastening mechanism used is mostly that two semicircular or semielliptical clamps move relative to each other, and the circular tube is squeezed by the generated pressure. Clamping, the clamping effect is poor, and to ensure the clamping effect when clamping round pipes of different diameters, it is often necessary to replace the fastening mechanism of different sizes, which cannot meet the needs of actual production
