Description

technical field

[0001] The invention belongs to the technical field of belt conveyors, and in particular relates to a device for detecting whether the belt bearing surface on a belt conveyor is torn. Background technique

[0002] In the current cargo loading and unloading operations in ports and mines, material conveying devices play a vital role, mainly including three parts: reclaimer, belt conveyor and stacker. Among them, the belt conveyor is mainly used to transport the coal, ore and other dispersed materials scooped up by the reclaimer to the stockyard, and stack them through the stocker. During the operation of the belt conveyor, the belt is often torn due to sharp foreign objects such as iron plates and wood mixed in the material that penetrate the bearing surface of the belt. The belt tear problem not only affects the safety of the belt conveyor line, but also affects the production efficiency of the entire material yard. Especially with the increasing size, effic...

Examples

Embodiment 1

[0025] Embodiment 1, the existing belt conveyor is mainly composed of a frame 1, a belt 2 for conveying dispersed materials, a motor for driving the belt 2 to run, and a load bearing that supports the belt 2 during the operation of the belt 2. The idler unit consists of 3, combining figure 1 , figure 2 shown. Wherein, the carrying roller unit 3 mainly includes two parts of the roller 4 and the roller frame, see figure 2 As shown, the idler frame is used to support the idler 4, including the main components such as the column 5, the rotating shaft 6 and the bottom beam 7. Among them, the idler 4 is set on the rotating shaft 6, and the two ends of the rotating shaft 6 are fixed on the column 5, and are supported by the bottom beam 7; the column 5 can be erected on the ground, or can be hung on the frame 1 of the conveyor, see Figure 4 shown.

[0026] When loading and unloading materials, the materials shoveled by the reclaimer are transferred to the belt 2 of the conveyo...
