Problems solved by technology
[0003] In actual work, in order to prevent the deflection angle of the above-mentioned steel wire rope from being too large, the operating speed of the tower crane is limited, and the operating speed of the tower crane is usually set to be relatively low, which reduces the working efficiency of the tower crane
[0004] Aiming at the problem that the steel wire rope swings relatively large during the working process of the tower crane in the related art, no effective solution has been proposed so far

Embodiment Construction
[0027] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0028] Because the tower crane lacks the hoisting wire rope anti-sway device or has no anti-sway function, the swing range of the steel wire rope is completely controlled by reducing the luffing speed, which reduces the work efficiency. At the same time, due to the swing of the hoisting weight, the tower crane will generate periodic torque, bending moment and overturning moment, which will affect the stability of the system and bring great danger to construction workers working at heights. Based on this, the embodiment of the present invention provides a method, device and system for controlling the driving force of the trolley of the tower crane. The following is described by way of examples.

The invention provides a method, a device and a system for controlling the trolley driving force of a tower type crane. The method comprises the following steps: acquiring the operation parameters of the trolley of the tower type crane within an appointed time; acquiring angle deviation parameters of the steel wire rope of the tower type crane within the appointed time; and controlling the driving force of the trolley according to the operation parameters and the angle deviation parameters. According to the invention, larger amplitude of swing of the steel wire rope can be removed quickly, and the running speed of the trolley is enabled to be maintained within a reasonable range, therefore, the hoisting security and the working efficiency are enhanced.
Description
technical field [0001] The present invention relates to the field of engineering machinery, and more particularly, to a method, device and system for controlling the driving force of a trolley of a tower crane. Background technique [0002] When the luffing mechanism of the existing tower crane is in operation, the trolley moves horizontally. Due to the effect of inertia, the center position of the hoisting weight will deviate from the center position of the trolley, and the steel wire rope will have a deflection angle. Swing and overturning moments seriously affect the stability and positioning accuracy of the system. When the running speed of the trolley is high, due to the effect of inertia, the deflection distance of the hoisting weight is relatively large, and the deflection angle of the lifting wire rope is relatively large. In actual production, there is no way to quickly eliminate the deflection angle of the lifting wire rope, only to reduce the amplitude speed to r...
