Carrier roller abnormality detection system and method for belt conveyor patrolling robot

Abstract

The invention provides a carrier roller abnormality detection system and method for a belt conveyor patrolling robot. The system comprises an RFID label used for marking the position of a carrier roller set, a pickup arranged on the patrolling robot and used for collecting carrier roller set running noise, a heat imaging camera arranged on the patrolling robot and used for collecting the temperature of the carrier roller set, a wireless radio frequency reader-writer arranged on the patrolling robot and used for reading the RFID label so as to recognize the position where the current detected carrier roller set is located, and a control master board used for obtaining data of the pickup, the heat imaging camera and the wireless radio frequency reader-writer and judging the carrier roller set abnormality situation based on data information. The carrier roller abnormality detection system is a system for collecting carrier roller running state data during belt conveyor running, predictingand monitoring the carrier roller abnormal running phenomenon during belt conveyor running and giving an alarm, damage to a belt from abnormal carrier rollers can be prevented, and the advantages ofthe low risk, low cost, stability and high efficiency are achieved.

Description

technical field [0001] The invention mainly relates to the relevant technical field of a detection device on an intelligent inspection robot, in particular to an abnormal detection system and method for an idler roller used for a belt conveyor inspection robot. Background technique [0002] Belt conveyor is an important equipment for transporting ore, coal, etc. in ports, mines, power plants and other enterprises. Idler failure and belt failure are two typical failure forms of belt conveyors, and idler failure is a major cause of belt failure. cause. The faults of the idler mainly include: 1. After the rotation resistance of the idler increases, the circumference of the pipe body is worn out, which will cause the risk of the belt being cut; 2. The bearing of the idler is damaged and stuck, which will cause the continuous friction between the idler and the belt to generate high temperature , may cause the belt to burn or even cause a fire hazard. [0003] Belt damage will c...

Problems solved by technology

The faults of the idler mainly include: 1. After the rotation resistance of the idler increases, the circumference of the pipe body is worn out, which will cause the risk of the belt being cut; 2. The bearing of the idler is damaged and stuck, which will cause the continuous friction between the idler and the belt to generate high temperature , which may cause the belt to burn or even cause a fire hazard

[0003] Belt damage will cause huge economic losses. In order to detect idler failures in time and save manpower, there are two main methods, one is indirect monitoring through abnormal noise or high temperature detection, and the other is through detection of the gap between the conveyor belt and the idler. Direct monitoring of the relative displacement between them; the specific implementation methods are: 1. Install a temperature or noise sensor on each roller. The disadvantages of this method are obvious. Due to the large number of rollers, the installation and maintenance workload is huge and the cost is high; If only one kind of sensor is installed, it is easy to be affected by the interference heat source or interference noise, resulting in false detection; and in the harsh operating environment, the sensor is prone to failure, the detection function will fail and even increase the safety hazard; 2. Passing on the belt Install multiple groups of fault detection modules that can convert the relative displacement between the conveyor belt and the idler into digital signals sent wirelessly, and combine the wireless receiving module and the alarm output circuit to realize real-time monitoring of abnormal idlers. Although this method reduces the installation work amount, but because it needs to be installed on the belt, it increases the manufacturing process and cost of the belt, and it is difficult to ensure the long-term normal operation of the equipment under the condition of direct load for a long time. Compared with the first method, the workload of maintaining the sensor is actually reduced It becomes the workload of maintaining the belt, and the maintenance cost is not low, and the positioning accuracy of the abnormal roller of the high-speed conveyor is poor, which affects the judgment of maintenance and repair personnel
