How to evaluate the stability of lockers under long-term load?
Publish Time: 2024-12-05
In various places, lockers often need to carry a large number of items and remain stable for a long time, which is crucial to their safety and practicality. To evaluate the stability of lockers under long-term load, it is necessary to consider many factors.
First of all, the material and structure of the cabinet are the key. High-quality steel or thick engineering plastics have high strength and rigidity and can withstand greater pressure. From a structural point of view, a reasonable frame design, such as the use of reinforcing ribs and reasonable layout of horizontal and vertical beams, can effectively disperse the load and prevent the cabinet from deforming. For example, some industrial lockers use heavy steel frames with thick plates. When heavy objects such as heavy machinery parts are placed for a long time, the cabinet can still remain square and stable without obvious bending or shaking.
Secondly, the firmness of the connection parts cannot be ignored. Whether it is welding, bolt connection or mortise and tenon structure (for wooden lockers), sufficient strength must be guaranteed. The welding should be uniform, without cracks and cold welding; the bolts should be selected with appropriate specifications and tightened to prevent loosening under long-term vibration or gravity. For example, in the sports equipment room of a school, lockers need to store heavy objects such as dumbbells and basketball hoops for a long time. If the connection parts are not firm, it is easy to cause problems such as skewed cabinet doors and cabinets falling apart, affecting safety and life.
In addition, the contact and support method between the base and the ground also affect stability. A wide and flat base can increase friction with the ground and reduce the possibility of sliding or tipping over. Some lockers are also equipped with adjustable feet to adapt to uneven ground and further enhance stability. Like in the supermarket storage area, lockers are frequently opened and closed and may be bumped by customers. A good base design can keep them in place under long-term load and dynamic use environment without shaking easily.
In addition, simulating long-term load testing of lockers is an important means of evaluation. Loading tests can be carried out at several times the designed load-bearing weight for a certain period of time to observe the deformation of the cabinet, changes in the connection parts and overall stability. At the same time, considering the uneven load that may exist in actual use, an eccentric load test is also required to simulate the scene where items are concentrated on one side or one corner to test the anti-eccentric load ability of lockers. Only by passing rigorous tests and meeting relevant standards can we ensure that lockers are stable and reliable under long-term load conditions, meet the storage needs of different places and users, ensure the safety of item storage, and reduce safety hazards and economic losses caused by unstable cabinets.
