Belt tearing detection device for belt conveyor

Abstract

The invention discloses a belt tearing detection device for a belt conveyor, wherein a belt and a load bearing roller unit are arranged in the belt conveyor, the load bearing roller unit comprises a roller and a roller frame; the belt tearing detection device comprises a detecting rod and a limiting switch, the detecting rod is located at the lower side of the belt, and the two ends of the detecting rod are respectively installed on upright posts at the left and right sides of the roller frame or left and right supporting frames independently arranged to be close to the upright posts; the limiting switch is installed on at least one upright post or supporting frame, and the detecting rod acts in case of collision with an object penetrating the belt to trigger the limiting switch to output a detecting signal indicating the belt tearing situation to a controller. The belt tearing detection device disclosed by the invention has the advantages of simplicity in structure, convenience for installation and debugging, low manufacturing cost, capability of performing adaptability adjustment according to different utilization occasions, high detecting precision, strong adaptability, safety and reliability; besides, the original structure of the belt conveyor is not damaged necessarily.

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...

Problems solved by technology

[0003] Because when foreign matter is inserted into the belt and the belt is torn, the belt will not be spilled. Therefore, it is not possible to find whether the belt is torn only through the inspection of the appearance, which buryes hidden dangers for the safe operation of the belt conveyor.

The belt tear detection device is used to detect whether the belt is torn during operation and to ensure the safety of the belt. There are two types of conventionally used belt tear devices for stackers and reclaimers: one is The steel wire rope anti-tear switch is extremely unstable and reliable in action, and the reuse rate is low, so it is difficult to accurately detect whether the belt is torn. But it is expensive and cumbersome to install
