Description

Technical Field

[0001] The utility model relates to the technical field of truck leaf spring disassembly, in particular to a leaf spring quick disassembly and assembly tool. Background Art

[0002] In heavy-duty vehicles and machinery, such as mining trucks, leaf springs are a crucial component of the suspension system, supporting the vehicle body and providing shock absorption. However, in actual operation, due to long-term exposure to complex and variable load conditions and harsh operating environments, truck leaf springs often suffer varying degrees of damage. This damage can occur in the middle or bottom of the leaf spring group, and there is no clear pattern to its occurrence.

[0003] Traditionally, when a leaf spring is damaged, repair personnel face a tedious and dangerous task. Because leaf springs are typically installed in multiple layers, the damaged spring is covered by intact springs above. Therefore, all intact leaf springs above must be manually removed one by one before replacement. This process is not only time-consuming and labor-intensive, significantly increasing the time and cost of the repair, but also places high demands on the operator's physical strength.

[0004] Especially on large machinery like mining trucks, leaf spring assemblies are often large and heavy. Manually removing them one by one is not only inefficient but also poses significant safety risks. For one thing, heavy leaf springs can easily become uncontrollable during removal, causing injuries to the operator, such as being crushed or crushed. Furthermore, prolonged, high-intensity labor increases operator fatigue, further increasing the potential for accidents. Summary of the Invention
