The cylinder body epimere of described upset hydraulic cylinder is fixedly supported on the upper surface of steel construction underframe, sinks in the cavity of ground in cylinder body under hypomere.
The hinged support of the left side plate of described upset hydraulic cylinder piston rod end and travel(l)ing rest is positioned at the left side plate middle and lower part of travel(l)ing rest and the side of close column, and after making travel(l)ing rest overturn 105 °, described hinged support is positioned on the line of centres of hot-metal bottle horizontal level cross central line and two rotary supports.
Described upset hydraulic cylinder is oscillating motor.
The advantage that the present invention has and effect:
1, inverting action power of the present invention is born by steel construction underframe, then is passed to ground by steel construction underframe entirety, and therefore foundation of civil work uniform force, reduces the cost of ground; Underground is sunken under particularly overturning hydraulic cylinder body section major part, the height of C.G. of upset travel(l)ing rest is reduced greatly, and then the height of C.G. of hot-metal bottle when also reducing work, and adopt two upset hydraulic cylinder and dual-gripper rotary support, tipping stability is significantly improved.
2, the present invention can realize hot-metal bottle flip angle and reaches 105 °, ensures that in tank, molten iron all flows out; Hydraulic system pressure≤25MPa; Tank body reversal rate 10-30min, tank body sinking speed 3-7min, can ensure ingot bar, point tank technological requirement completely.
3, the present invention can realize in arbitrarily angled This vehicle stops frequently in tank body upset or descent, and can carry out skims operation and eliminate molten iron knot covers.
4, structure of the present invention is simple, bearing capacity is strong, easy to operate, operate steadily, reliability is high, and equipment dynamic is little, and operating cost is low, it is simple and convenient to safeguard.

Detailed description of the invention
Below in conjunction with Fig. 1,2,3,4, a kind of embodiment of the present invention is described.
A kind of hydraulic turnover device of hot metal ladle, have steel construction underframe 1, and steel construction underframe 1 is fixed on ground 2; Described steel construction underframe 1 bilateral symmetry is fixed with two upset hydraulic cylinder 3, two columns 4 and two cushioning support-saddles 5, and two upset hydraulic cylinders 3 lay respectively between two columns 4 and two cushioning support-saddles 5; The top of described two columns 4 is all fixed with rotary support 6, and the front beam symmetry of travel(l)ing rest 7 is hinged on two rotary supports 6, and rear cross beam seat is on two cushioning support-saddles 5; The tailpiece of the piston rod symmetry of described two upset hydraulic cylinders 3 is hinged on the left side plate of travel(l)ing rest 7; Described travel(l)ing rest 7 rear cross beam is provided with locking cylinder 8 and locking bearing pin 9, and one end of locking bearing pin 9 is hinged with the tailpiece of the piston rod of locking cylinder 8, and the locking pin-and-hole 12 bottom locking bearing pin 9 and hot-metal bottle 10 on side otic placode 11 is matched.
The cylinder body epimere of described upset hydraulic cylinder 3 is fixedly supported on the upper surface of steel construction underframe 1, sinks in the cavity of ground 2 in cylinder body under hypomere.The hinged support of the left side plate of described upset hydraulic cylinder 3 tailpiece of the piston rod and travel(l)ing rest 7 is positioned at the left side plate middle and lower part of travel(l)ing rest 7 and the side of close column 4, and after making travel(l)ing rest 7 overturn 105 °, described hinged support is positioned on the line of centres of hot-metal bottle 10 horizontal level cross central line and two rotary supports 6.Described upset hydraulic cylinder 3 is oscillating motor.
During use, the hot-metal bottle of iron foundry (shop) or steelshop is transported to by blast furnace ironmaking workshop, to be put on travel(l)ing rest 7 by traveling crane and all around to locate, then stretched out by the piston rod of HYDRAULIC CONTROL SYSTEM locking cylinder 8, promoting locking bearing pin 9 inserts in the locking pin-and-hole 12 bottom hot-metal bottle 10 on side otic placode 11, hot-metal bottle and travel(l)ing rest is locked; Stretched out by HYDRAULIC CONTROL SYSTEM upset hydraulic cylinder 3 piston rod again, promote travel(l)ing rest 7 and slowly overturn with certain speed together with the rotary support 6 of hot-metal bottle 10 around column 4 top, molten iron is overflowed with comparatively uniform flow, turn to 105 ° of molten iron and be finished down.Retracted by HYDRAULIC CONTROL SYSTEM upset hydraulic cylinder 3 piston rod after molten iron is finished down, travel(l)ing rest 7 gets back to horizontal level together with hot-metal bottle 10, now reduces impulsive force when upset hydraulic cylinder 3 shrinks return by cushioning support-saddle 5; Retracted by the piston rod of HYDRAULIC CONTROL SYSTEM locking cylinder 8, drive locking bearing pin 9 return that travel(l)ing rest 7 and hot-metal bottle 10 are unlocked, traveling crane waits for lower subjob from empty hot-metal bottle again.
The present invention is worked by HYDRAULIC CONTROL SYSTEM upset hydraulic cylinder 3 and locking cylinder 8; realize the locking of hot-metal bottle 10, tumble, return, unlocking motion; in the swage that molten iron evenly, continuously through Molten iron chute is flow to pig machine or little ladle, realize the object of molten iron ingot bar or point tank.Reversal rate is controlled by hydraulic operation platform by operating personnel, and can realize hot-metal bottle 10 and to overturn or in descent, in arbitrarily angled This vehicle stops frequently, carrying out skimming operation and eliminating molten iron knot lid.
Above-described embodiment, just preferred embodiment of the present invention, is not used for limiting the scope of the present invention, therefore all equivalent variations done with content described in the claims in the present invention, all should be included within the claims in the present invention scope.
