slag ladles 45, and simultaneously, the slag in the slag ladle 45 is also constantly toppled over.When slag ladle 45 was in state shown in Figure 2, the slag in jar had all been toppled over.Driving oil cylinder 42 is shunk then, drives swing hold-down arm 41 and rotates, with slag ladle 45 pull-ups.After driving oil cylinder 42 is withdrawn into position before the tank switching, front leg strut 21 withdrawals, then cross cylinder 223 shrinks, but case beam 222 and the flexible rear support leg 22 of level are withdrawn into the position of tinning operation, and supporting leg 224 withdrawals are embraced a tank car and are got back to state as shown in Figure 1.So far, the tank switching operation finishes.When needs take off extension, being about to tractor truck 1 breaks away from so that change or during maintenance from superimposed trailer 2, quick coupling with the pneumatic and hydraulic tubing between tractor truck 1 and the superimposed trailer 2 earlier disconnects, two front leg struts 21 with superimposed trailer 2 stretch out again, with the wheel together support superimposed trailer 2 on they and the superimposed trailer 2, also 4 hydraulic rams all can be stretched out, with superimposed trailer 2 jack-up.Afterwards, tractor truck 1 goes out to throw off and being connected of superimposed trailer 2 from saddle 4, takes off the extension operation and finishes.When embracing a tank car and carry out loading, unloading, tank switching operation, rod chamber 421 and rodless cavity 422 that hydraulic oil enters driving oil cylinder 42 through the change-over valve 6 and the explosion relief valve group 7 of dual-circuit hydraulic system.There is any one when breaking when connecting hydraulic tubing between the explosion relief valve group 7, oil pressure in this pipeline will descend immediately, 7 meetings of explosion relief valve group are closed at the utmost point will connect this pipeline that breaks in the short time valve port, stop fluid to flow out, and another pipeline that connects explosion relief valve group 7 still can keep being communicated with, make hydraulic efficiency pressure system continue normal operation, like this, driving oil cylinder 42 with regard to can not be because the pipeline oil pressure reduces suddenly get out of hand and then cause the generation of accident.Therefore, dual-circuit hydraulic system can be avoided owing to a hydraulic tubing that connects driving oil cylinder 42 breaks serious contingency taking place when embracing the tank car operation.
