Lifting type silo comprehensive monitoring mechanism

Abstract

The invention relates to a mechanical lifting mechanism, in particular to a lifting type silo comprehensive monitoring mechanism, which belongs to the technical field of mechanical automation. The lifting type silo comprehensive monitoring mechanism comprises a housing support frame, wherein a transmission mechanism and a pulley roping mechanism are fixed on the housing support frame; a safety protection device and a hanging basket are fixed on the base plate of the housing support frame; the transmission mechanism consists of a motor and a speed reducer; the speed reducer is integrated with the motor; a roller is arranged on the output shaft of the speed reducer; a low temperature-resisting communication cable is wound on the roller while the roller is rotated, passes through an upper limit protection mechanism along the guiding pulley roping mechanism and is connected with the hanging basket; and a plurality of kinds of sensors are arranged on the hanging basket. The device can have the following functions of: 1, controlling lifting by using a programmable logic controller (PLC) program; 2, automatically measuring the height of a coal level in a silo; and 3, automatically and accurately detecting parameters such as related gas concentration, temperature and the like at a specific position.

Description

technical field [0001] The patent of the invention relates to a mechanical lifting mechanism, in particular to a comprehensive monitoring mechanism for a lifting silo, which can realize real-time monitoring in a closed silo and can be freely controlled by PLC programming, and belongs to the technical field of mechanical automation. technical background [0002] Recently, with the development of industry, various large-scale closed storage bins have also appeared, especially the storage of coal in large coal-consuming enterprises and coal mining industries and the storage of grain in granaries, making the safety of large-scale closed storage bins Monitoring is becoming more and more important. Since large storage warehouses are generally tall and relatively closed, the comprehensive monitoring of various safety hazards in the storage warehouse has become a big problem. Due to the different safety hazards in closed storage warehouses, In terms of detection, a large number of m...
