Lift type comprehensive monitoring mechanism

Abstract

The invention relates to a mechanical lift mechanism, specifically to a lift type comprehensive monitoring mechanism belonging to the technical field of mechanical automation. The lift type comprehensive monitoring mechanism comprises a housing supporting frame, wherein a transmission mechanism and a pulley rope-winding mechanism; a safety protection device and a basket are fixed to the base plate of the housing supporting frame; the transmission mechanism is composed of a motor and a speed reducer, the two of which are integrated with each other; a drum is mounted on the output shaft of the speed reducer; the drum rotates so that a low temperature resistant communication cable is wound around the drum; the cable is connected with the basket via an upper limiting protection mechanism along the guide pulley rope-winding mechanism; and various sensors are mounted on the basket. The lift type comprehensive monitoring mechanism is capable of accomplishing the following functions of: 1, controlling the lifting thereof by means of a single chip program; 2, automatically measuring the height of the coal level in a silo; and 3, automatically and accurately detecting parameters such as related gas concentration, temperature and the like in a specific position.

Description

technical field [0001] The patent of the invention relates to a mechanical lifting mechanism, in particular to a lifting comprehensive monitoring mechanism, which can realize real-time monitoring in a closed silo body and can be freely controlled by a single-chip microcomputer 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...
