分析筒式柴油打桩锤的工作原理和结构特点,针对某大吨位筒式柴油打桩锤工作中存在的锤击时间较长后打桩锤的起跳次数增加,打击能量下降,特别是随着打击时间的延长,自然停车频次增加,影响了打桩效率的问题进行分析,提出解决对策和措施。通过改进,增加了大吨位筒式柴油打桩锤的空气量,改善了燃烧情况,燃油在一个循环内燃烧更充分;在热锤状态空气量的泄漏明显减少,同时确保打桩锤在工作较长时间后,最大的打击能量不会降低。
The working principle and structural characteristics of drum diesel pile hammer are analyzed. In view of the existence of long hammering time in a large tonnage drum diesel hammer, the number of take-offs of pile hammer increases and the striking energy drops, especially with the impact of time Extend, natural frequency of parking increases, affecting the efficiency of piling analysis, propose solutions and measures. Through the improvement, the air volume of the large-tonnage diesel pile hammer was increased, the combustion condition was improved, and the combustion of the fuel was more complete in one cycle. The leakage of the air mass in the state of the hot hammer obviously decreased, and at the same time, the pile hammer was ensured to work for a long time After the maximum combat energy will not be reduced.
