Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor belt dust cover installation, and relates to an easy-to-install and detachable belt conveyor belt dust cover fixing device. Background Art

[0002] The DTⅡ belt conveyor is a versatile conveying device featuring a simple structure, easy maintenance, high reliability, strong conveying capacity, long conveying distances, and strong adaptability. It is widely used in bulk material conveying applications such as chemical processing, docks, coal mining, metallurgy, and grain. Depending on the process requirements, the belt conveyor can be arranged horizontally or inclined, and can also utilize a combination of convex and concave arc segments and straight segments.

[0003] The "DTⅡ(A) Belt Conveyor Design Manual" provides a relatively brief description of belt conveyor belt dust covers. However, the design of a typical DTⅡ belt conveyor requires installation of belt dust covers on exposed sections of the conveyor belt outside the range of movement of the stacker, reclaimer, and ship loader. The belt dust covers are constructed of galvanized, painted, colored corrugated steel sheet, at least 0.8mm thick, offering excellent strength, rigidity, and durability. They are connected to the frame with stainless steel fasteners. Inspection windows are located at regular intervals on both sides of the belt cover. The belt dust cover must extend no less than 0.5m into the transfer room and must be tightly fitted at the entrance and exit points to protect against wind and rain.

[0004] Belt conveyor belt dust covers are typically installed using angle steel to support Z-shaped steel, secured with tile hooks. The angle steel, Z-shaped steel, and side support channel steel are welded together, and the belt dust cover is secured to the Z-shaped steel with tile hooks. However, in actual operation, it has been found that after long-term use, the angle steel and Z-shaped steel in this installation method are prone to weld cracks, rust, and fracture at the welded areas, leading to collapse of the belt dust cover. In addition, the large-area contact between the Z-shaped steel and the belt dust cover can easily cause rust and corrosion at the edges of the belt dust cover, resulting in collapse.

[0005] Due to the increased probability of the above two types of damage, repairing the damaged belt dust cover requires a lot of manpower and time. When a large area collapses, it will have a great impact on production. In view of this situation, in order to reduce the impact of long-term downtime on production during the replacement and installation process, the present utility model is specially proposed.
