Embodiment Construction

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0038] see figure 1 , the deviation correction control method in the traveling process of bridge crane cart of the present invention, comprises the following steps:

[0039] S1: Real-time detection of real-time displacement signals on both sides of the cart during the traveling of the cart;

[0040] S2: Comparing the real-time displacement signals on both sides of the cart, the displacement difference will be obtained;

[0041] S4: Use the displacement difference as a control signal to control the traveling speed and displacement on both sides of the cart to adjust the deviation on both sides.

[0042] Directly obtain the real-time displacement of both sides of the gantry, and perform deviation correction control by calculating the displacement di...

Abstract

The invention discloses a deviation rectification control method and system for a car of a bridge crane in the walking process. The method comprises the steps of detecting real-time displacement signals on the two sides of the car in real time in the walking process of the car; comparing the real-time displacement signals on the two sides of the car for obtaining a displacement difference value; adopting the displacement difference value as a control signal and controlling the walking speed and the displacement of the two sides of the car for adjusting the deviation of the two sides. The system comprises a detection module used for detecting the real-time displacement signals on the two sides of the car in real time in the walking process of the car, a comparison module used for comparing the real-time displacement signals on the two sides of the car for obtaining the displacement difference value, and a deviation rectification controller used for adopting the displacement difference value as the control signal and controlling the walking speed and the displacement of the two sides of the car for adjusting the deviation of the two sides. According to the deviation rectification control method and system, the deviation problem in the walking process of the car of the bridge crane can be effectively solved, the stability in the operation process of the bridge crane can be improved, the maintenance cost can be lowered, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the safety control of the cart in the technical field of bridge cranes, in particular to a deviation correction control method and system during the traveling process of the cart of the bridge crane. Background technique [0002] Bridge crane is a kind of lifting and transportation device erected inside or outside the factory building. It is shaped like a bridge and is also called a crane. In modern large-scale production, bridge cranes have become indispensable production equipment for many industrial and mining enterprises. It consists of one or two main girders and two end girders. It runs on the track laid on the bearing girder. It is generally equipped with 4 wheels (6 or 8 wheels when the load is large) ). Bridge cranes have been widely used in industrial production, and are the most widely used and most numerous hoisting machinery. [0003] Due to the characteristics of large span, low horizontal rigidity, many parts,...
