目的了解蔬菜大棚内不同类型作业和身体部位的姿势负荷情况。方法选取186名从事棚内作业6个月以上的人员,应用OWAS方法对不同类型作业活动进行姿势编码分析,探讨其不同作业和身体部位的姿势负荷。结果棚内不同类型作业及身体部位的姿势各不相同。异常姿势(4级)在不同作业中呈较大差异,以搬运作业最高,其次为配药、喷药,两者主要发生于下肢和背部,而棚内作业的高负荷主要为搬运。结论蔬菜棚内作业的姿势负荷与作业类型有关,虽大多数为1级姿势,但异常姿势(4级)在各作业中仍占一定比例,均需要立即加以纠正和克服。
Objective To understand the posture load of different types of homework and body parts in vegetable sheds. Methods A total of 186 personnel engaged in shed operation for more than 6 months were selected to conduct pose coding analysis of different types of homework using OWAS method to study the posture load of different homework and body parts. As a result, the posture of different types of homework and body parts varied. Abnormal postures (grade 4) showed a large difference in different jobs, with the highest handling, followed by dispensing and spraying, both of which occurred mainly in the lower extremities and backs while the heavy load of shed operations was mainly handled. Conclusions The posture load of vegetable shed operations is related to the type of operation. Although most of them are in level 1 posture, the abnormal posture (level 4) still occupies a certain proportion in each operation and needs to be corrected and overcome immediately.
