Problems solved by technology

This method requires a special person to be on duty, which not only wastes manpower costs, but also fails to detect the abnormal situation of belt tearing in time, resulting in the belt conveyor continuing to work and increasing the degree of belt tearing, which seriously affects the normal operation of the belt conveyor.

Embodiment Construction

[0040] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0041]It should be noted that, in the present invention, the belt of the belt conveyor is annular and closed, and the belt of the belt conveyor moves circularly. The upper belt 4 and the lower belt 8 in the present invention refer to the upper and lower layers of the belt conveyor at a certain moment. Since the belt is in circular motion, when the belt is torn, it may be that the belt on the upper layer is torn, or the belt on the lower layer may be torn, but there is always a moment when the tear will move to the upper layer of the belt conveyor And be detected, so the upper layer belt tear mentioned in the present invention is not only to detect whether the belt on the upper layer is torn, it is also possible that ...

Abstract

The invention relates to a belt longitudinal tearing protection device of a belt machine, a comprehensive protection device and a system. The longitudinal tearing protection device comprises first detecting modules, a mobile light stop plate and mechanical touch rods. The first detecting modules are arranged on an upper-layer belt of the belt machine; the mechanical touch rods are arranged below the upper-layer belt at intervals in the width direction of the upper-layer belt, are parallel to the belt surface of the upper-layer belt, are supported and suspended through brackets arranged on two sides of the upper-layer belt, and can swing between the two brackets; and the mobile light stop plate is arranged at one ends of the mechanical touch rods, is positioned between the first detecting modules, and can swing along with the mechanical touch rods. The belt longitudinal tearing protection device can timely discover the belt tearing for stop, realizes real-time automatic belt monitoring, saves the labor cost, effectively prevents influence on normal production by further belt tearing, and is convenient in installation and higher in sensitivity.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a protection device for belt longitudinal tearing of a belt conveyor, a comprehensive protection device and a system. Background technique [0002] For long-distance belt transportation industries such as mining, mineral processing, and logistics, the safe operation of belt conveyors is very important. Common failures of belt conveyors include slipping, deviation and plugging. Once one of the above failures occurs, the feed belt will be scratched or torn immediately. Not only does it cost money to repair or replace the belts, it also delays production. Some factories and mines have also taken some protective measures. The original domestic longitudinal tear protection device basically relies on external mechanical force to trigger the output switch of the sensing element to detect the belt conveyor and stop the electrical transmission of the belt conveyor. This met...
