The invention is further described below in connection with the principle of operation:
LNG cryogenic fluid loading arm extension arm 2 pitch up position definition: when the outer arm of the loading arm (the fluid loading arm is provided with an inner arm, an outer arm and an extension arm, and the extension arm is connected to the outer end port of the outer arm) is over-large in dip angle or the tank car interface is relatively low, the extension arm needs to be turned upwards to realize parallel or concentric butt joint of the tail end of the extension arm and the tank car interface. Because the outer arm is upward bent to a certain extent, and the outer arm is excessively downward bent to be out of control easily, the gas phase outer arm and the liquid phase outer arm are easy to collide with each other to cause equipment damage, and therefore the upward bending position of the outer arm is limited by arranging a balancer stroke. The upward tilting of the extension arm is realized by the relative sliding of the shaft sleeve 33, the guide shaft 34 and the inner sleeve 31 and the outer sleeve 32, and when a clamping block 37 on the outer wall of the inner sleeve 31 touches a limiting block 36 on the inner wall of the outer sleeve 32, the upward tilting of the extension arm reaches the limit position;
the LNG cryogenic fluid handling arm extension arm dip position defines: when the upward angle of the outer arm of the loading arm is overlarge or the tank car interface is relatively high, the outer arm is required to be downward bent to realize parallel or concentric butt joint of the tail end of the outer arm and the tank car interface, and the outer arm is excessively upward bent to be out of control easily because of a certain range, so that equipment is damaged due to easy collision between the gas-phase outer arm and the liquid-phase outer arm, and the position limitation of downward bending of the outer arm is realized by arranging a balancer stroke. The downward movement of the cantilever arm is achieved by the relative sliding movement of the shaft sleeve 33 and the guide shaft 34 and the inner sleeve 31 and the outer sleeve 32, when the guide shaft 34 hits against the inner-side top piece of the shaft sleeve 33 (reaching the downward limit position of the cantilever arm when the guide shaft 34 is fully inserted into the shaft sleeve 33 if the stroke of the inside of the shaft sleeve 33 is longer than the length of the guide shaft 34) or when the elastic member 35 is compressed to the limit position.
