直插式振捣器是我国建筑施工中使用最广的振捣工具。据国家有关计量部门测试,目前常用的振捣器手柄处的振动加速度均超过国家卫生标准,已对作业工人产生明显的职业危害。我所科研人员经过努力探索,研制出一种四点错位式新型减振器以及相应的手把结构,使操作手柄处的振动加速度达到国家卫生标准,能有效地保护工人身体健康。 The in-line vibrator is the most widely used vibrating tool in the construction of our country. According to tests conducted by the relevant measurement departments of the country, the vibration acceleration at the handle of the commonly used vibrators exceeds the national health standards and has caused significant occupational hazards to workers. Our research staff has worked hard to explore and develop a new type of four-displacement shock absorber and corresponding handle structure, so that the vibration acceleration at the operating handle reaches the national health standards and can effectively protect the health of workers.
