Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor technology, specifically relating to a belt conveyor tear protection detection device. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are a type of continuous conveying equipment widely used in industrial production. They transport materials through the continuous movement of a conveyor belt, offering advantages such as long transport distances, large transport capacity, simple structure, stable operation, and ease of operation. The working principle of a belt conveyor involves a motor driving a rotating drive drum. The friction between the drive drum and the conveyor belt drives the belt's movement. Materials placed on the conveyor belt are transported to their designated positions as it moves. During operation, idler rollers support the conveyor belt, a tensioning device adjusts the belt tension, and a cleaning device removes residual material from the belt surface, ensuring stable operation of the belt conveyor.

[0003] However, during the transportation process, the conveyor belt of a belt conveyor may sometimes detach or shift, posing a risk of belt tearing. Therefore, this application provides a belt conveyor tear prevention and detection device that detects whether the belt is torn and provides timely feedback to prevent further tearing.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a belt conveyor anti-tear protection detection device to detect whether the belt is torn and provide timely feedback to prevent the tear from spreading further.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A belt conveyor tear protection detection device includes:

[0008] The support frame has an n-shaped structure, and the gap between the vertical bars on both sides allows the belt to pass through;

[0009] A laser rangefinder sensor is mounted on the top crossbar of the support frame, with its illumination direction vertically downward toward the belt surface;

[0010] An audible and visual alarm is installed on the top crossbar of the support frame.

[0011] Preferably, one guide roller is provided on the inner side of each of the two vertical rods of the support frame, and the height of the guide roller corresponds to the height of the side of the belt.

[0012] As preferred, the laser ranging sensors are symmetrically arranged 2 on the top crossbar of the support frame.

[0013] As preferred, the acousto-optic alarm is located between the two laser ranging sensors.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) the belt conveyor anti-tearing protection detection device of the utility model, through install two sets of laser ranging sensors on the top crossbar of the support frame, can detect the position change of the belt when the belt tears, and interlock with the belt shutdown signal, and further prevent the belt tear from further expanding.

[0016] (2) the belt conveyor anti-tearing protection detection device of the utility model, when the belt tear triggers the belt conveyor shutdown, can trigger the acousto-optic alarm simultaneously, reminding the operator to handle in time.

[0017] (3) the belt conveyor anti-tearing protection detection device of the utility model, 1 baffle roll is arranged in each of the inside of the vertical pole of the support frame, can prevent the belt from separating or deviating, and plays the role of protection device.
