Device capable of preventing inertia swing of unmanned overhead crane clamp

Abstract

The invention relates to a device capable of preventing inertia swing of an unmanned overhead crane clamp. The device is composed of a trapezoid cover connecting beam, a trapezoid cover, a trapezoid plug and a trapezoid plug connecting beam which are sequentially arranged from top to bottom; the lower end of the trapezoid plug connecting beam is fixed to the unmanned overhead crane clamp, and the upper end of the trapezoid plug connecting beam is fixedly connected with the trapezoid plug; and the upper end of the trapezoid cover connecting beam is fixed to the bottom of a trolley of an unmanned overhead crane, the trapezoid cover is fixed to the lower end of the trapezoid cover connecting beam and corresponds to the trapezoid plug, and internal space of the trapezoid cover is matched with the shape of the trapezoid plug. According to the device, the trapezoid plug and the trapezoid cover are used for connecting the clamp at the high position with the trolley of the unmanned overhead crane, and therefore flexible connection between the clamp and the overhead crane through a steel wire rope is converted into rigid connection, synchronous operation of the clamp and the trolley in the overhead crane variable motion process is guaranteed, the clamp swing angle is prevented, stable running of the unmanned overhead crane is guaranteed, and the working efficiency of the overhead crane is improved.

Description

technical field [0001] The invention relates to a device capable of preventing the tongs of an unmanned crane from swinging greatly during the operation of the crane, and belongs to the technical field of lifting equipment. Background technique [0002] The unmanned crane adopts advanced crane control technology, which puts forward high requirements on the operating parameters of each component of the crane. The clamp swing angle is an important factor affecting the running stability and work efficiency of the unmanned crane, so the control of the clamp swing angle of the unmanned crane is particularly important. For example, in the process of dynamic take-up and unwinding, the clamp is generally required The swing angle can be controlled within 0.5 degrees, otherwise it will be impossible to realize the precise stacking of steel coils in the warehouse. [0003] The reason for the swing angle of the clamp of the crane is that the clamp and the hoist of the crane are general...
