Description
Technical field: the invention belongs to metallurgy conticaster Processes and apparatus field, is a kind of intermediate tank four cylinder hydraulic lifts.
Background technology: the lifting of intermediate tank has two kinds of forms on the conticaster intermediate tundish carriage, and a kind of is electronic Worm gear ball leading screw thousand top formulas, and a kind of is hydraulic actuating fluid cylinder pressure formula.The former structure complexity, being watered the steel loop border influences, and worm and gear and ball-screw are fragile, so the service expenditure height, change the operating rate that has frequently also influenced casting machine in addition.The latter is simple in structure, but commonly used both at home and abroad at present is plunger case two cylinder formulas, increase along with tundish capacity, for making two cylinder formulas safe and reliable to operation must increase the diameter or the system pressure of cylinder, this just makes physical construction too huge, or system pressure is too high, and the stability of two cylinder formulas operation is not very high.
Summary of the invention: the purpose of this invention is to provide a kind of intermediate tank four cylinder hydraulic lifts, it is simple that it has a compact conformation, and investment, operation, service expenditure are low, reliable operating rate height.
The object of the present invention is achieved like this, intermediate tank four cylinder hydraulic lifts, it is by the lifting beam, lifting and guiding device, hydraulic actuating cylinder supporting, hydraulic efficiency pressure system are formed, and two the lifting beams in both sides are the steel structure weldment, are provided with the bearing of supporting intermediate tank gudgeon above, the two ends of lifting beam are provided with the orienting roll driving wheel, and the track adjusting wheel restriction lifting beam at two ends is in the skew of interior outer arc or left and right sides; Lifting and guiding device is the steel structure welding, in establish guiding and establish plate, two hydraulic cylinder piston rod tops, both sides are connected with the lifting beam by hinge, and cylinder body is installed in by the flange bearing on the traveling vehicle frame of intermediate tundish carriage, and hydraulic efficiency pressure system mainly is made up of Hydraulic Pump, valve group, pipe arrangement.
Advantage of the present invention is: by the lifting beam, and lifting and guiding device, hydraulic actuating cylinder supporting, hydraulic efficiency pressure system are formed intermediate tank four cylinder hydraulic efficiency pressure systems, HM Hydraulic Motor makes four hydraulic actuating cylinder actions, make the lifting in guide frame of lifting fine strain of millet, thereby drive the intermediate tank lifting, finish continuous casting technological operation requirement.Adopt this method and device can realize intermediate tank steadily lifting synchronously: can in lifting process, stop arbitrarily, lock; When overload, has the overpressure protection effect; Can adjust rising or falling speed according to operation technological requirement, compact overall structure is simple, and investment, operating cost are reduced, and service expenditure also reduces simultaneously, and improves the running job rate.
Description of drawings:
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is an embodiment of the invention structural representation.
Among the figure, 1, by pass valve 2, check valve; 3, HM Hydraulic Motor; 4, balance cock: 5, one-way throttle valve A; 6, one-way throttle valve B; 7, electro-hydraulic reversing valve; 8, hydraulic control one-way valve; 9, safety valve 10, high-pressure ball valve A; 11, high-pressure ball valve B; 12, hydraulic actuating cylinder 13, lifting beam, 14, guide frame: 15, intermediate tank.
The specific embodiment: intermediate tank four cylinder hydraulic lifts, it is by lifting beam 13, lifting guide frame 14, hydraulic actuating cylinder 12, intermediate tank 15, hydraulic efficiency pressure system is formed, intermediate tank 15 are placed on the lifting beam 13, about 15 two of intermediate tank, lifting beam 13 is driven by two following hydraulic actuating cylinders 12, each lifting beam 13 is by two lifting guide frames, 14 guiding, two lifting beams in both sides 13 are the steel structure weldment, be provided with the bearing of supporting intermediate tank gudgeon above, the two ends of lifting beam 13 are provided with the orienting roll driving wheel, track adjusting wheel restriction lifting beam 13 skews at interior outer arc or left and right sides at two ends: lifting guide frame 14 is the steel structure welding, in establish the guiding establish plate, two hydraulic actuating cylinders, 12 piston rod tops, both sides are connected with lifting beam 13 by hinge, hydraulic actuating cylinder 12 is installed on the traveling vehicle frame of intermediate tundish carriage by the flange bearing; Pressure oil makes 12 actions of four hydraulic actuating cylinders by one group of HM Hydraulic Motor 3, drives the lifting in guide frame 14 of lifting beam 13, thereby drives intermediate tank 15 liftings, finishes the technological operation requirement.
Hydraulic efficiency pressure system is made up of pipe arrangement, HM Hydraulic Motor 3, by pass valve 1, check valve 2, balance cock 4, one-way throttle valve 5, one-way throttle valve 6, electro-hydraulic reversing valve 7, hydraulic control one-way valve 8, safety valve 9, high-pressure ball valve 10, high-pressure ball valve 11.HM Hydraulic Motor is cascaded by the same axis rigidity, arrives the HM Hydraulic Motor of terminal point position oil circuit earlier, still is rotated further under other motor drives, and this road pressure oil is forced through by pass valve 1 and gets back in the system.On each bar oil circuit of HM Hydraulic Motor 3 in-to-ins a by pass valve 1 and check valve 2 are arranged all, form a valve group by them, pressure oil is flowed back to by by pass valve 1 for a long time, pressure oil after a little while, then check valve replenishes, thereby eliminates the accumulated error of each lifting travel.The hydraulic actuating cylinder that may cause because of deadweight when balance cock 4 descends for preventing intermediate tank or motor is out of control is provided with.One-way throttle valve 5,6 running velocitys with the regulator solution cylinder pressure.Electro-hydraulic reversing valve 7 is used for the action commutation of hydraulic actuating cylinder, and hydraulic control one-way valve plays fluid control, and hydraulic tank stops in lifting process at an arbitrary position in the middle of can making, and safety valve 9 plays the function of protection hydraulic actuating cylinder for preventing the load superpressure, and valve 10 is a high-pressure ball valve.
