Lifting and carrying system

Abstract

The invention relates to the technical field of cement production, and particularly relates to a lifting and carrying system. The lifting and carrying system comprises a crane and an electrical control system, the electrical control system comprises a controller and variable-frequency driving devices, the crane comprises a crane carriage, a crane span structure, an object taking gripping apparatus and a lifting mechanism carried on the crane carriage, the lifting mechanism comprises a lifting motor and a transmission device, the crane carriage is arranged on the crane span structure, the crane carriage is provided with a carriage walking motor used for driving the crane carriage to move, the crane span structure is provided with a crane span structure walking motor used for driving the crane span structure to move, the lifting motor is connected with the object taking gripping apparatus through the transmission device, the crane carriage is provided with weighing sensors, the carriage walking motor, the lifting motor and the crane span structure walking motor are all connected with corresponding independent variable-frequency driving devices, and the variable-frequency driving devices and the weighing sensors are all connected with the controller. The speed regulation of the crane is stable and smooth, an automatic operation function is realized, the working intensity of operators is reduced, and the operators are enabled to work far away from a hostile environment.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a lifting and conveying system. Background technique [0002] At present, the cement kiln joint storage is a common raw material storage and transportation workshop in cement production. It stores iron ore, gypsum, rock, coal, and mixed materials inside. Each raw material is put into different transmission lines by the crane in the workshop. Usually the cranes used in the combined storage are manually controlled. Due to the early construction period, the cranes do not have the functions of frequency conversion speed regulation, three-dimensional positioning detection, material detection, and automatic program control. The airtightness of the electric control room and the operation room is poor and the work intensity is high , The working environment is bad. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems e...
