Problems solved by technology

[0010] In the above technical solutions, the temperature measuring optical cable is mainly installed on the roller bracket or the truss channel steel. Their disadvantage is that they cannot directly detect the temperature of the idler roller, but indirectly detect the temperature of the roller bracket or the farther truss channel steel.
The inability to directly measure temperature is the shortcoming of these technical solutions
[0011] In addition, the existing technology has limited space for installing temperature measurement optical cables. In order to obtain normal measurement results, it is often necessary to coil a certain length of optical cables and stuff them into roller brackets or protective containers.
This kind of coiling with many turns and small bending radius will greatly increase the additional loss of the optical fiber and seriously reduce the actual working distance of the detection optical fiber

Abstract

The invention relates to a belt conveyor, in particular to a belt conveyor with a linear detector. The belt conveyor comprises support rollers and the linear detector. A shaft of each support roller is tubular. Each support roller is provided with a channel penetrating in the axial direction. The linear detector is arranged in the channels. In this way, the linear detector can directly detect the temperature or other state quantities of the support rollers.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to a belt conveyor with a linear detector. Background technique [0002] Belt conveyor is an important transportation equipment in metallurgy, mining, power, building materials, transportation and other industries. During its operation, many factors will cause slippage between the belt and the idler roller, which will cause the surface temperature of the roller to rise rapidly, forming a fire hazard. Due to the long distance of the belt conveyor and the large number of rollers, manual inspection is difficult, and conventional point detectors are not suitable. At present, the latest monitoring method adopts linear temperature-sensitive detectors. [0003] These new linear temperature detectors mainly include distributed optical fiber temperature sensors, temperature sensing cables, etc. Distributed optical fiber temperature sensor has at least four implementation technologies: ROTDR based on Ram...
