Application on conveyor belt and coal transport trestle

According to actual situation, there are 2 options:

Plan A

If the width of conveyor belt is less than 0.4m, protect it with an equal length of optical fiber sensor cable. Optical fiber cable can be fixed directly on the appendant right above the centre of the conveyor belt less than 2.25m. The appendant can be a supporting wire or original fixture. Supporting wire’s function is offer a support. Every 75m fixed with a bolt to fit the supporting wire.

To prevent optical fiber cable falling down, every 4m-5m fix it with a fixture to lock the optical fiber cable with supporting wire. The material of the supporting wire should be 2mm stainless steel wire(or replaced with galvanized steel wire ).

The installation method as shown figure.

Plan B

If the width of conveyor belt over 0.4m, optical fiber cable can be located at both side of the conveyor belt, optical fiber sensor cable is installed in a heat-conducting box next to ball bearings to detect overheat caused by bearing friction and coal powder accumlation.

Generally design and install principle is on the premise of having no influence with usual operation and maintenance according to actual situation.

If necessary, such as in a high fire risk environment, the optical fiber cable can be laid both on the right above and two side of the conveyor belt. The installation method as shown figure.
