Abstract
The utility model relates to equipment used for slab continuous casting machines in the metallurgical industry, particularly to a hydraulic rotary joint of a slab continuous casting machine. The technical scheme is as follows: the hydraulic rotary joint comprises a rotary joint movable side (1), shift forks (2 and 3), supports (4 and 5) and a rotating body (6); the rotary joint movable side (1) is matched and connected with the rotating body; the shift forks and the supports are arranged on the two surfaces of the rotary joint respectively; and the shift forks are arranged on the rotating body through the supports. The hydraulic rotary joint of the slab continuous casting machine has the benefits of allowing the rotary joint to rotate more stably under the high-voltage heavy load, ensuring more uniform stress, reducing the swinging phenomenon of the rotary joint, reducing the tension of the rotary joint ground bolt, ensuring the operational stability and the reliability, reducing the work load of equipment maintenance, eliminating the loss of unplanned shutdown caused by the equipment failure and providing the guarantee for the normal production.
Description
Affiliated technical field:
The utility model relates to the hydraulic rotary joint that a kind of metallurgy industry plate connects base casting machine equipment, particularly slab caster.
Background technology:
Hydraulic rotary joint is the core position of conventional slab caster, also is one of equipment of emphasis.Its effect mainly is: rotate synchronously with turntable when big bag turntable rotation, provide the path of oil inlet and oil return for wrapping all hydraulic equipment on the turntable greatly.This rotary joint structure is cylindrical, and be divided into two parts up and down: the latter half is that fixed body is fixed on big bag turret base center, fixing port formula bolting, and no alignment pin is fixed with four high-strength bolts; The first half is that bascule is used to connect big bag turntable hydraulic test and rotates synchronously with big bag turntable under the shift fork effect.At present, swivel joint the first half two shift forks of single face and the one-sided stressed synchronous rotation of turntable rotary body, bear the high pressure of 20 MPas in the course of the work because of the swivel joint body, in operation process, cause very big resistance, add single face shift fork discontinuity, cause swivel joint body top single face stressed when rotated.Because of selecting adapter direction of rotation when working fixing, up time, the counterclockwise both direction of pin all move, and make swivel joint under this stressed situation, and the body lower margin is difficult to fix, and the phenomenon that the swivel joint foundation bolt is loosening even cut off often occurs.In process of production, just in case wherein two bolts cut off and will cause hydraulic rotary joint integral shift or inclination, the effect that can not play choosing commentaries on classics fuel feeding causes the damage of interior all hydraulic conduit failure of turntable and electrical equipment, after making that big in process of production bag turntable especially ladle out of control sliding plate hydraulic controlling organization can not be controlled, may cause that molten steel is excessive, serious security incidents such as splash breaking out of fire or casualties, the equipment aspect cause swivel joint to damage and platform on the damage of visual plants such as crystallizer, middle hired car.And in regular maintenance, often because this swivel joint lower margin fixedly expends a large amount of manpower and materials, and this equipment no safety guarantee that is in operation.
The utility model content:
The utility model purpose provides a kind of hydraulic rotary joint of slab caster, make swivel joint more stable in the heavy load rotation of band high pressure, stressed more even, reduced the dancing of swivel joint, reduced the pulling force of swivel joint foundation bolt, guarantee this operation stability of equipment and reliability, solved the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the hydraulic rotary joint of slab caster comprises swivel joint active side, shift fork, support, revolving body, the swivel joint active side is connected with the revolving body coupling, two sides at swivel joint all is respectively equipped with shift fork and support, and shift fork is arranged on the revolving body by support.
Adopt the utility model, change into two-sided stressed symmetrically and evenly when making the swivel joint rotation by original single face local pressure, when having eliminated the two shift forks rotation of single face to the local outer active force of swivel joint, make swivel joint more stable in the heavy load rotation of band high pressure, stressed more even, reduced the dancing of swivel joint, reduced the pulling force of swivel joint foundation bolt, avoided the joint body lower margin the generation of the imaginations such as bolt looseness cut-out, guarantee this operation stability of equipment and reliability, thereby also eliminated the generation that hydraulic rotary joint produces hidden danger such as the potential safety hazard brought after the fault and device damage.
The beneficial effects of the utility model are: make swivel joint more stable in the heavy load rotation of band high pressure, stressed more even, reduce the dancing of swivel joint, reduced the pulling force of swivel joint foundation bolt, guaranteed this operation stability of equipment and reliability; Reduce the working strength of safeguarding this equipment simultaneously, stopped to cause when therefore equipment breaks down the loss of non-programmed halt, brought guarantee for the production direct motion.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure: swivel joint active side 1, shift fork 2 and 3, support 4 and 5, revolving body 6.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The hydraulic rotary joint of slab caster comprises swivel joint active side 1, shift fork 2 and 3, support 4 and 5, revolving body 6, the swivel joint active side is connected with the revolving body coupling, two sides at swivel joint all is respectively equipped with shift fork and support, and shift fork is arranged on the revolving body by support.The utility model, when having eliminated the two shift forks rotation of single face to the local outer active force of swivel joint, make swivel joint more stable in the heavy load rotation of band high pressure, stressed more even, guarantee this operation stability of equipment and reliability, thereby also eliminated the generation that hydraulic rotary joint produces hidden danger such as the potential safety hazard brought after the fault and device damage.
