Topic.
With reference to operating principle, the invention will be further described：
LNG low temperature fluid handling arms overhanging arm 2 is faced upward position restriction：When the outer arm of loading arm（Fluid assembly and disassembly arm is equipped with inner arm, outer
Arm and overhanging arm, overhanging arm are connected on the outer end port of outer arm）Nutation angle is excessive or when tank car interface is relatively low, needs
Overhanging arm face upward to realize that overhanging arm end is parallel with tank car interface or concentric docking.Facing upward because of outer arm has a certain range, simultaneously
The excessive nutation of overhanging arm is easily out of control so that easily collides with so as to cause equipment damage, therefore passes through between gas phase, liquid phase overhanging arm
Setting balancer stroke limits the position that overhanging arm is faced upward to realize.Overhanging arm face upward through pipe spreader 33 and guiding axis 34 and
Inner sleeve 31 is opposite with outer tube 32 to be slided to realize, when the fixture block 37 on 31 outer wall of inner sleeve is encountered on 32 inner wall of outer tube
Limited block 36 when, overhanging arm is faced upward the position that reaches capacity；
LNG low temperature fluid handling arm overhanging arm nutation position restrictions：When the outer arm tilt angle of loading arm is excessive or tank car interface
When relatively high, needing nutation overhanging arm, overhanging arm end is parallel with tank car interface or concentric docking reaching, because of outer arm nutation
Have a certain range, at the same overhanging arm excessively face upward it is easily out of control so that easily collide between gas phase, liquid phase overhanging arm so as to cause
Equipment damage, therefore realize that the position of overhanging arm nutation limits by setting balancer stroke.Overhanging arm nutation passes through pipe spreader
33 with guiding axis 34 and inner sleeve 31 are opposite with outer tube 32 slides to realize, when guiding axis 34 is encountered in 33 inside of pipe spreader
During the jacking block of side（It is when guiding axis 34 is completely inserted into axis if the stroke inside pipe spreader 33 is more than 34 length of guiding axis
Reach the nutation extreme position of overhanging arm during casing 33）Or when elastic component 35 is compressed to extreme position, overhanging arm nutation reaches
Extreme position.
