Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors and faulty roller replacement, and more particularly to a conveyor frame device and a use method thereof. Background Art

[0002] Belt conveyors used in underground coal mines are essential equipment for coal mining operations. During operation, idlers support and transfer materials, making them a core component of the conveyor. Due to the unique floor conditions of coal mine tunnels, idlers often misalign with the conveyor belt, impacting the belt's service life. Nuts and iron blocks are often used to raise the idler frames, severely impacting the idler's stability. Belt conveyor idlers are also susceptible to damage from various factors, including coal dust, moisture, high temperatures, and heavy loads. Faulty idlers require prompt replacement. Currently, most idlers are manually carried to the faulty location. This process requires lifting the conveyor belt with a guide chain and manually replacing the idler. If the faulty idler is on the non-pedestrian side, the operator must cross the belt conveyor to access the non-pedestrian side for replacement. However, space is often limited on the non-pedestrian side, making idler replacement inconvenient, time-consuming, and labor-intensive. If multiple idlers are required for replacement, more workers are required to handle them. Although the existing crawler roller replacement robot can replace rollers, it is greatly affected by the tunnel size and tunnel floor conditions, and can only replace the upper rollers, and has not been widely promoted.

[0003] In view of this, it is necessary to improve the conveyor rack device in the prior art to solve the above problems. Summary of the Invention
