Abstract

The invention relates to a control system for an automatic jacking tank of electric hoists. The control system comprises n central supports, n electric hoists, a control device, a positioning device and a slideway, the central supports are fixedly arranged on the inner side of the tank, the electric hoists are fixed on the central supports, the electric hoists are divided into basic electric hoists and adjusting electric hoists, the positioning device is mounted on the lower portion of the tank, the slideway is arranged at positions on the central supports and corresponding to the positioning device and matched with the positioning devices, and the control device comprises a PLC (programmable logic controller), a weighted limiting switch and at least one inclination angle sensor. By the control system, the problems of positioning of the lower portion of the tank and inclination degree control of the tank or re-balancing of the tank after inclining when the jacking tank with the electric hoists invertedly mounted are solved.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a control system for an electric hoist to automatically lift a tank body, which is mainly used for construction of an industrial tank body by the upside-down method. Background technique [0002] At present, the construction of industrial tank body inversion method is mainly carried out by electric hoist and hydraulic device. Compared with the inversion method of hydraulic device, the electric hoist inversion method has the advantages of simple equipment, easy operation and low cost. And no consumables such as hydraulic oil and pressure components are used, so that there is no oil leakage, no pollution to the working environment, and no adverse effects on the welding process of the tank due to oil leakage at the weld. However, there are two major problems to be solved in the electric hoist inversion method: one is the positioning of the tank during the jacking process, and the other is the ...
