The invention relates to a contraposition temperature measuring device for a mining belt type conveyer. The contraposition temperature measuring device comprises a belt type conveyer host, multiple temperature sensors, multiple temperature converters, a liquid crystal display and an alarm, wherein the belt type conveyer host is provided with a single-chip microcomputer, the temperature converters has multi-path real-time detection input interfaces, each input port respectively detects temperature signals at different parts of the belt type conveyer, the temperature sensors are mounted at multiple different positions of the belt type conveyer, the temperature sensors, the temperature converters and the single-chip microcomputer are sequentially connected, and the liquid crystal display and the alarm are respectively connected with the single-chip microcomputer. The contraposition temperature measuring device is advantaged in that: multi-path real-time detection parts for contraposition temperature measuring are arranged, a temperature measuring scope is expanded, and a temperature measuring utilization effect is improved, moreover, based on a temperature over-limit alarm function, a specific temperature value and a specific fault position of the belt type conveyer can further be displayed, so corresponding measures for temperature reduction and overhaul can be conveniently carried out, and temperature protection accuracy and overhaul efficiency are greatly improved.
Description
technical field [0001] The invention relates to a detection device, in particular to an alignment temperature measurement device of a mine belt conveyor. Background technique [0002] Temperature protection is an important part of the comprehensive protection device for mine belt conveyors. At present, most belt conveyor temperature detection methods pre-set the temperature critical value, and then compare it with the temperature collected by each sensor to determine whether the temperature exceeds the limit, and then Decide whether to shut down for inspection or not by means of switching value. This temperature protection method is relatively simple, but the disadvantage is that it can only generally determine whether the temperature exceeds the limit, and the specific value and position of the temperature exceedance cannot be accurately provided. The effective improvement of the production efficiency of the type conveyor does not meet the requirements of the modernization...
