Novel intelligent stand column swing arm crane

Abstract

The invention relates to a novel intelligent stand column swing arm crane. The novel intelligent stand column swing arm crane comprises a stand column. Strengthening plates are evenly arranged on the outer sides of the lower end of the stand column. Jacking rotating tables are arranged between a lower supporting plate and an upper supporting plate. Auxiliary plates are arranged between the upper supporting plate and the stand column. The upper portion of the stand column is sequentially provided with an annular rail and an annular guide rail from bottom to top. A rotating shaft is connected with the top end of the stand column. A bearing box is connected with the upper end of the rotating shaft. A safety hook is connected with the left end of the bearing box. A weight sensor is arranged in a lifting tool. The upper supporting plate is arranged at the top ends of the jacking rotating tables. A connecting pillar is connected with the lower end of the upper supporting plate. The lower end of the connecting pillar is connected with a rotating table. A lifting seat is connected with the lower end of the rotating table. Hydraulic cylinders are connected with the lower ends of the left side and the right side of the lifting seat. The lower ends of the hydraulic cylinders are connected with the lower supporting plate. The input end of a lighting device is connected with a PLC. Thus, the novel intelligent stand column swing arm crane is high in automation and intelligence degree, powerful in function, stable in operation and high in safety degree.

[0002] With the development of the national economy, hoisting machinery has become an indispensable equipment for many departments. Under the conditions of modern mass production, with the continuous improvement of the mechanization and automation of technological processes, hoisting machinery in the production process, from Auxiliary equipment has gradually become a special equipment in the continuous production process. Under the condition of continuous development of production technology, there are more and more types of cranes. Cranes) are two of them that are widely used. Cranes are a kind of intermittent action machinery, and their working characteristics are periodic. In each working cycle, his main mechanism makes a forward and reverse movement, and each cycle Including the loading and unloading of items, the journey of carrying items and the return of the empty hook after unloading, and the short pause between the two loading and unloading, including the auxiliary preparation time. Most of the current column swing arm cranes are a column plus a rotating mechanism and a main beam at the upper end, and then corresponding auxiliary lifting equipment is set up on these basic frames. This column swing arm crane The function of the rotating and lifting mechanism is too single, and its lifting height is adjusted solely by the lifting of the wire rope on the spreader, and its lifting range is limited. The rotating mechanism has a limited range of rotation. In the end, the response of the crane when it is limited to load or has an inclination angle depends too much on the experience of the operator. Its safety is not enough, and its degree of automation is low, which cannot meet the requirements of high-efficiency operations.
