Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor technology, and more specifically, it relates to a belt conveyor anti-tear protection device. Background Technology

[0002] A belt conveyor is a machine that uses friction to continuously transport materials. It mainly consists of a frame, conveyor belt, idlers, drums, tensioning devices, and transmission devices. It is suitable for conveying powdery, granular, small lump materials, and bagged materials, and is widely used in mining, power plants, ports, electronics, food, chemical, and light industries. This equipment is divided into two categories: heavy-duty belt conveyors (such as mining conveyors) and light-duty belt conveyors.

[0003] Based on the above, the inventors have discovered the following problems: some belt conveyors may tear during operation, but the belt conveyors lack anti-tear protection devices, making it difficult for workers to detect and deal with the tearing problem in a timely manner, which can easily affect material conveying and production processes, making them inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a belt conveyor anti-tear protection device in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effect of this utility model's anti-tear protection device for belt conveyors are achieved by the following specific technical means: A belt conveyor tear protection device includes a support frame, a set of fixing plates installed at the bottom of the support frame, a set of laser rangefinders installed at the top of the support frame, an mounting plate installed at the top of the laser rangefinders, fixing components installed on the surface of the mounting plate, and an audible and visual alarm installed at the top of the support frame.

[0006] Furthermore, the fixing component includes a plurality of threaded holes extending through the surface of the fixing plate, wherein a fixing bolt is installed in the internal thread of the threaded hole.

[0007] Furthermore, the top of the support frame is provided with several threaded holes II, which are matched with fixing bolts. One end of the fixing bolt passes through the threaded hole I and is installed into the interior of the threaded hole II.

[0008] Furthermore, two sets of support plates are installed on the inner side of the support frame, and a guide roller is installed inside each set of support plates via a rotating shaft.

[0009] Furthermore, a fixing hole is provided through the surface of the fixing plate.

[0010] Furthermore, a controller is installed on one side of the support frame, and the controller is electrically connected to each electrical appliance.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By using laser rangefinders and audible and visual alarms in combination, two sets of laser rangefinders are installed on the top of the device. When the belt tears, it contracts towards the center. The distance detected by the laser rangefinders on both sides is greater than the set position, triggering the laser rangefinders to activate. This activation signal is interlocked with the belt stop signal, thus preventing the tear from spreading further. At the same time as the belt stops, the audible and visual alarm is triggered to remind the operator to handle the situation in time. It has dual detection, high signal recognition rate, and prevents belt tears from affecting material conveying and production processes.

[0012] 2. The design of the guide rollers can prevent the belt from slipping or shifting, and also protect the device. Attached Figure Description
