Summary: | The invention provides an advanced hydraulic support traveling mechanism lift device and a control method thereof. The advanced hydraulic support traveling mechanism lift device comprises an advancedhydraulic support, connecting seats, lift jacks, a traveling mechanism, electro-hydraulic control valves and synchronous valves, wherein the advanced hydraulic support and the traveling mechanism areconnected through hinge pins to constitute a supporting body jointly, the contact state between an advanced hydraulic support base and a roadway bottom plate can be changed by controlling actions of the lift jacks, cylinder tube cavities and piston rod cavities of the lift jacks are connected with the synchronous valves respectively, and the synchronous valves guarantee that the lift jacks ascendand descend at the same speed; when the lift jacks act, guiding surfaces of lift seats move up and down, external force produced when the advanced hydraulic support or the traveling mechanism deflectsand swings is overcome by t |
