Problems solved by technology

The anti-swing method using rigid sleeves is more commonly used in lifting equipment. Its advantages are high alignment accuracy and can meet the requirements of high productivity, but the disadvantage is that due to the heavy weight of the rigid sleeve itself, it increases the lifting capacity. The calculated load of the mechanism increases the power of the motor and the structure, which leads to an increase in the wheel pressure of the whole machine and increases the cost of the factory building
In addition, the processing cost of the rigid guide cylinder is relatively high, and the maintenance cost also increases accordingly.

Embodiment Construction

[0014] Figures 1 to 3 show an example of the application of the double "inverted splayed" wire rope anti-sway winding system formed according to the method of the present invention to the hoisting mechanism of an electromagnetic hanging beam crane. This electromagnetic hanging beam crane is composed of six major parts: electrical equipment 1, trolley 2, cart operating mechanism 3, bridge frame 4, truss-type hanging beam 5, and electric hoist 6. There is a set of hoisting mechanisms on both sides of the trolley, and each set of hoisting mechanisms contains a double "inverted character" shaped wire rope anti-swing winding system. Figure 4 and Figure 5 respectively show the arrangement of the components of the wire rope anti-sway winding system on the trolley and the hook. It can be seen from Fig. 6 that a set of hoisting mechanism includes two steel wire ropes to form a structure of four ropes. From Fig. 6, it can be seen that the two strands of steel wire ropes on the left come...

Abstract

A method for preventing the swinging of pylon and steel plate when a pylon-type electromagnetic hoister is started or stopped features that two steel cables used between the bogie and hook of lifting unit are respectively wound on pulleys to a dual-reverse-splayed system to effectively provent said swinging.

Description

technical field [0001] The invention relates to an anti-swing method for lifting heavy objects by a crane, in particular to an anti-swing method for hanging a beam and a steel plate when an electromagnetic hanging beam crane starts and brakes. Background technique [0002] Electromagnetic hanging beam cranes are necessary steel plate and slab loading and unloading equipment for steel mills and ports. At present, the length of the steel plate lifted by the existing electromagnetic hanging beam crane in the steel plant is generally less than 18m. With the continuous demand of the manufacturing industry and the continuous development of rolling technology, steel plants, ports and manufacturing industries have the demand for handling ultra-long steel plates. It will inevitably increase rapidly, so an electromagnetic hanging beam crane capable of lifting long steel plates is required. To manufacture this electromagnetic hanging beam crane, it is necessary to solve the swinging p...
