Arm outer end the Oil Guide mouth of pipe on anti-overflow control valve is installed；Meanwhile, overhaul positioned at outer oil pipe and increase between support and Three dimensional joint
If immediately below one section of rotatable oil fuel tube and the oil fuel tube outer end alignment Three dimensional joint, band is installed at oil fuel tube middle part therein
There is the anti-overflow valve of oil diverting port.
Correspondingly, arrange between the upper rope sheave and outer arm support component and column and support case, positioned at inner arm drive mechanism
One section of upper staircase is installed in column outside between maintenance platform, and outer arm drive mechanism reverse side is provided with retaining mechanism.
Ultralow temperature with anti-overflow pipeline of the present invention loads and unloads having the beneficial effect that for arm configuration：
(1) driven by independent inner arm, outer arm drives and horizontal drive mechanism, is capable of achieving global and local mechanism
Electrichydraulic control, improves the flexible operation degree of inside and outside arm, while being furnished with nitrogen blowing mechanism, makes each several part of joint in low temperature
Working condition under shrink uniform, it is minimum to efficiently solve low temperature lower sealing surface and deform uneven problem to -197 DEG C,
So as to solve a low temperature seal difficult problem；
(2) being passed through nitrogen makes raceway being dried all the time in whole cargo handling process, it is ensured that moisture in air will not be in raceway
Freeze and damage raceway；
(3) by the preventing oil spill pipeline section that belt supporting frame is installed positioned at the inner arm pipe section exterior between gudgeon case and maintenance platform
And the anti-overflow control valve with the Oil Guide mouth of pipe is opened up positioned at pipeline section middle part, the spilling when fluid is full of tank body can be effectively prevented
Phenomenon, it is ensured that the safe transport of various fluids, eliminates potential safety hazard.
