A brief analysis of the tail frame design for roller conveyor equipment

Thread Content

The frame of a roller conveyor system is a steel structure that holds the rollers, idlers, conveyor belt, materials, as well as various cleaning and tensioning devices; it is capable of withstanding impacts, tensile, compressive, and bending stresses. Racks are divided into rigid and flexible types. Rigid frames can be either fixed or mobile, while flexible frames rely on steel cables to support the idlers; for the conveyor belt to drive the frame, it must be rigid. The frame of roller conveyor equipment can be classified according to the materials used: 1. The steel structural frame for roller conveyor equipment, made from standard steel sections or special-shaped steel pipes. 2. Steel pipe frame for roller conveyor equipment. The frame can be welded to steel pipes; for long-distance roads, ordinary seamless steel pipes can also be used as frames. The steel pipe can transport both water and oil, serving two purposes at once. 3. Concrete frame for roller conveyor equipment. Made of concrete and appearing straight from a distance, it is the frame for roller conveyor equipment; this design reduces maintenance tasks such as rust removal. It is easy to install, and this method is commonly used for fixed-long-distance roller conveyor equipment. Both the head and tail frames of the roller conveyor equipment can be equipped with holes for bearing installations. 4. Fiberglass frame for roller conveyor equipment. It features high strength, corrosion resistance, and light weight, making it particularly suitable for use in environments such as seawater salt pans and chemical salt factories. On a per-weight basis, the price is slightly higher than before. For this planning, steel structural frames are mainly to be used. Design the frame using steel sections. As an important device for the continuous transport of materials, roller conveyor equipment is widely used in various sectors of the national economy. As a square bracket that serves as a support for the roller and bears its load, its structure is relatively simple. However, when performing calculations for this bracket, complex analyses of forces, deflections, and the stability of compression members are required; therefore, accurate design calculations demand considerable time and effort from the designers. Therefore, alongside actual planning, a simplified force checking method based on budgetary considerations is often used, resulting in support structures that fail to achieve optimization. Structural design of the tail frame for roller conveyor equipment: Arc welding is used for connecting the frames of roller conveyor equipment, as it offers advantages such as good weld quality and fast welding speed ； Moreover, the welding frame is lightweight, has a short production cycle, and low costs. The analogical method is adopted for planning: this planning approach involves making comparisons based on similar products that have proven effective in existing products, conducting appropriate analyses and simple calculations, and taking into account the actual production conditions. Design criteria for the frame of roller conveyor equipment: First, it is necessary to meet the requirements regarding strength and stiffness; secondly, the frame should have good stability in terms of stiffness; thirdly, it must fulfill the process requirements, facilitating manufacturing, installation, lifting, transportation, maintenance, etc.
