Safety pin system of pendulum impact testing machine based on sector structure and safety self-locking

针对摆锤式冲击试验机弹出式安全销的不足,以及冲击试验过程中摆锤意外释放可能对试验人员及设备带来伤害的问题,提出了一种具有安全自锁功能的扇形结构安全销系统。采用SolidWorks对安全销结构进行了设计,建立了冲击试验机控制系统的软件流程,设计了基于该扇形结构安全销系统防护的摆锤式冲击实验机,并进行了大量摆锤与安全销之间的破坏性撞击试验和冲击试验机的系统稳定性试验。研究结果表明:基于安全自锁功能的扇形结构安全销系统能有效防止摆锤意外释放及承受摆锤的反复撞击;研究结果可为开发与构建更高安全防护性能等级的摆锤式冲击试验机提供设计参考。

Aiming at the problems that the deficiency of pop-up safety of pendulum impact testing machine and the accidental release of pendulum can cause some potential harm to the tester and the equipment during the pendulum impact testing process, a safety pin system with sector structure and safety self-locking function was researched. The structure of safety pin was designed by using SolidWorks. The software flow of control system of pendulum impact testing machine was established. The pendulum impact testing machine based on the protection of the safety pin system was designed. A large number of destructive impact tests of between pendulum and safety pin and system stability tests of impact testing machine were conducted in the presented machine. The results indicate that the safety pin system based on sector structure and safety self-locking function can not only effectively prevent from the accidental release of the pendulum but also withstand the repeated impact of the pendulum,which can provide a reference for the development and construction of pendulum impact testing machine with a higher level of safety protection performance.
