A kind of grab anti-sway control method using driving to catch slag

Abstract

The invention discloses a grab bucket anti-sway control method using driving to grab slag, including: 1) constructing a slag grabbing system; 2) inputting the maximum running speed value V max and the acceleration a of the trolley; the anti-sway function module transmits the result to the frequency converter after performing calculations based on the above parameters. 0. After setting the anti-sway function module, you only need to input the maximum running speed value V of the car through the input terminal of the anti-sway function module max and the acceleration a of the trolley; ensure that the speed of the trolley drops to 0 when it starts running from 0 speed to directly above the target object, and at the same time, the swing of the grab is 0 during the uniform movement of the trolley, that is, the anti-swing effect of the grab is achieved. The anti-swing function module is adopted without real-time measurement of the swing angle of the grab bucket. The operation is simple, the efficiency is high, and the anti-sway effect is good.

Description

technical field [0001] The invention belongs to the technical field of crane anti-sway, and in particular relates to a grab bucket anti-sway control method using driving to grab slag. Background technique [0002] During the operation of the crane, due to the flexibility of the wire rope, the grab will inevitably shake when the cart and trolley stop running. Experienced operators will judge the shaking direction in advance based on experience and adjust the grab properly. The speed of the car or trolley can be used to eliminate the swing, but the swing cannot be completely avoided. [0003] During the operation of the slag grabbing crane, the automatic positioning and positioning accuracy of the cart and trolley play an extremely critical role. During the final positioning process of the crane, the hook or grab will inevitably shake. During automatic operation, when the grab shakes, it may touch the edge of the slag washing pool and then the grab rotating wire rope will be ...
