Abstract
The utility model discloses a rotatory hoisting device of hydraulic pressure, belong to electric arc furnace steelmaking production line technical field, it includes the lift arm, the lift shaft, a guiding sleeve, and a housing, swivelling joint axle and for nonoculture ram cylinder, the lift arm sets up the top at the lift shaft, periphery at the lift shaft is equipped with the uide bushing, the uide bushing sets up the top at the shell, the shell suit is in the periphery of swivelling joint axle, swivelling joint axle sleeve dress is in the lift shaft, the swivelling joint axle connects the setting soon on the piston rod of ram cylinder for the nonoculture. The utility model discloses a rotatory hoisting device of hydraulic pressure, simple structure, reasonable in design, occupation space is little, convenient operation, fail safe nature is high, only needs one set of pneumatic cylinder just can control entire system's operation for the furnace body operation is stable among the the smelting process, need not complicated control system, avoid arousing occurence of failure and blowing out maintenance because operating system goes up the trouble.
Description
Technical field
The utility model belongs to electric-arc furnace steelmaking production line technology field, is specifically related to hydraulic rotating lifting device.
Background technology
At present, in electric-arc furnace steelmaking production line, be all equipped with furnace cover lifting and rotational locking device.Need in good time reinforced in body of heater in smelting process, namely need to outward winding after furnace cover lifting.
This furnace cover lifting at home and abroad used and rotational locking device, general is all control the lifting of bell and the spin locking of bell respectively by two cover hydraulic cylinders, the interlocked relationship of two motions is realized again by electrical control, waste resource is compared in such design comparatively speaking, by the linkage relationship of electrically upper realization, there is no chain accurate, the safety of direct mechanical device; And often occur coordinating bad phenomenon due to furnace cover lifting with bell spin locking in reality is smelted, make arc smelting occur the phenomenon of interrupting; Because two cover hydraulic cylinders control two motions respectively, often occur bell after cycle, spin locking is not also locked, and what can affect body of heater in smelting time serious inclines to needs, affects normal smelting operation.
Utility model content
Goal of the invention: the purpose of this utility model is to provide hydraulic rotating lifting device, and not only rational in infrastructure, security performance is high, and it is little to take up room, is easy to maintenance and safeguards.
Technical scheme: for achieving the above object, the utility model adopts following technical scheme:
Hydraulic rotating lifting device, it comprises lift arm, lift shaft, fairlead, shell, be rotatably connected axle and single-acting piston type oil cylinder, described lift arm is arranged on the top of lift shaft, fairlead is provided with in the periphery of lift shaft, fairlead is arranged on the top of shell, outer cover suit is on the periphery being rotatably connected axle, and the axle sleeve that is rotatably connected is contained in lift shaft, the described axle that is rotatably connected spin be arranged on single-acting piston type oil cylinder piston rod on.
Being rotatably connected, axle upper and lower surface is all equipped with plane bearing.
Described plane bearing covers bolt by gland and fixes.
In the bearing block of described shell, be provided with rotary steering axle, the front end of rotary steering axle embeds in the stroke groove in lift shaft.
In the both sides of described rotary steering axle, deep groove ball bearing is set.
Described single-acting piston type oil cylinder is bolted on the flange of outer casing bottom.
Described lift arm is connected with the bell of peripheral hardware.
Beneficial effect: compared with prior art, hydraulic rotating lifting device of the present utility model, structure is simple, reasonable in design, take up room little, easy to operate, security reliability is high, only needs a set of hydraulic cylinder just can control the operation of whole system, makes body of heater in smelting process stable; Without the need to the control system of complexity, avoid because fault in operating system causes accident to occur and shutdown maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic rotating lifting device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, hydraulic rotating lifting device, comprise lift arm 1, lift shaft 2, fairlead 3, rotary steering axle 4, deep groove ball bearing 5, shell 6, the axle 7 that is rotatably connected, plane bearing 8, gland 9 and single-acting piston type oil cylinder 10, wherein lift arm 1 is connected with the bell of peripheral hardware.
Wherein, lift arm 1 is arranged on the top of lift shaft 2, is provided with fairlead 3 in the periphery of lift shaft 2, and fairlead 3 is arranged on the top of shell 6, shell 6 is sleeved on and is rotatably connected on the periphery of axle 7, the axle 7 that is rotatably connected spin be arranged on single-acting piston type oil cylinder 10 piston rod on.
Single-acting piston type oil cylinder 10 is bolted on the flange bottom shell 6.
The axle 7 that is rotatably connected is sleeved in lift shaft 2, and being rotatably connected, axle 7 upper and lower surface is all equipped with plane bearing 8, and plane bearing 8 covers bolt by gland 9 and fixes.
Arrange deep groove ball bearing 5 in the both sides of rotary steering axle 4, rotary steering axle 4 is arranged in the bearing block of shell 6, and the front end of rotary steering axle 4 embeds in the stroke groove in lift shaft 2.
The course of work: when oil pump is toward fuel feeding in single-acting piston type oil cylinder 10, single-acting piston type oil cylinder 10 drives lift shaft 2 to rise, simultaneously due to the effect of the stroke groove in lift shaft 2 and rotary steering axle 4, lift shaft 2 is forced to complete 90-degree rotation in the process risen, realize rising and the rotation of lift arm 1 or decline and rotate, thus completing lifting and the rotation of bell.
