Embodiment Construction

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0038]The belt conveyor consists of a belt, a driving pulley, a driven pulley and a bracket to support the pulley. The driving roller is driven by the motor, and the driven roller rotates under the friction of the belt.

[0039] The detection device of the belt conveyor includes a detection unit and a single-chip microcomputer integrated system for detecting the rotating speed of the drum.

[0040] Specifically, two sets of detection units can be provided, one set is used to detect the rotation speed of the driving drum, and the other group is used to detect the rotation speed of the driven drum.

[0041] The detection unit includes a positioning part 1, a radar detector 2 and a radar signal processor.

Abstract

The invention discloses a detection device for a belt conveyor. The detection device comprises a positioning piece, a radar detector used for detecting the positioning piece and a radar signal processor. The positioning piece is fixed to the side face of a roller, and the radar detector is fixed to the side of the roller and spaced from the positioning piece by a preset distance. The minimum detection distance and the maximum detection distance of the radar detector relative to the positioning piece are stored in the radar signal processor, and the radar signal processor only uses echo signalswith the detection distances being within the minimum detection range and the maximum detection range as effective signals for driving the rotating speed of the roller. In addition, a deviation valuecapable of automatically changing according to the targeted rotating speed of the driving roller is preset in a single chip microcomputer of the detection device, and the single chip microcomputer judges the slipping state of the belt conveyor and the fault states of the detection device and the belt conveyor according to the deviation condition of the targeted rotating speed and the rotating speed of the driving roller with the rotating speed of the driven roller. The detection device shields the interference of falling materials to the radar detector, and has the functions of belt slippingdetection and fault detection.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a detection device for belt conveyors. Background technique [0002] The belt conveyor is usually equipped with a speed detection device. At present, the speed detection device of the belt conveyor is roughly divided into two types: [0003] One type is a contact speed detection device. This type of detection device is equipped with a roller and a magnetic induction sensor. The roller is in contact with the belt. The magnetic induction sensor senses a signal through the rotation of the roller, and the belt speed is calculated using the sensed signal. The disadvantage of this type of detection device is that the rollers are easy to wear due to direct contact, and the speed deviation will increase after long-term use, resulting in inaccurate detection results. [0004] The other type is non-contact speed detection device, which is divided into external type and built-in typ...
