传统装车臂存在问题及改进措施
Problems and Improvement Measures of Traditional Loading Arms
摘要
Abstract
In order to improve the loading efficiency of the loading arm and reduce the labor intensity,the composition,work flow,problems and reasons of the traditional LNG loading arm are analyzed,and the improvement measures are put forward.By organically integrating various improvement measures with traditional LNG loading arm technology,a new type of pneumatic assist loading arm is designed and manufactured.By adding a cylinder between the inner arm and the frame,the inner arm is pushed around the first rotary joint rotates;the six manual valves are changed to pneumatic valves,and the control signal is connected to the batch controller through the explosion-proof junction box;a spring balance is added between the extension arm and the inlet flange of the fifth rotary joint cylinder,so that the extension arm can be kept horizontal within the envelope range;the quick-connect device is used instead of the loose flange to connect with the tank car to improve the efficiency of the connecting arm.The test operation of the new pneumatic assist loading arm is carried out at the LNG loading station.The results show that the new loading arm can improve the level of automation,and the use of its replacement of the traditional loading arm can reduce one operator,reduce the labor intensity of the remaining operators,and improve the work efficiency about 18%at the same time.关键词
