对棚车锁锁杆前端环槽部位的直径大小范围、结构和工艺进行计算和分析,探讨了通过控制棚车锁锁杆环槽部位的直径、结构和工艺来较好地防止棚车锁的二次施封,并通过试验验证了该措施对防止棚车锁二次施封的合理性和有效性,为棚车锁的进一步改进完善提供重要参考。
The size range, structure and process of the front ring groove of the lock lever are calculated and analyzed. It is discussed that the secondary lock of the box lock can be well prevented by controlling the diameter, structure and technology of the lock ring The test proves the rationality and effectiveness of this measure to prevent the second lock of the box lock and provides an important reference for the further improvement and perfection of the box lock.
