Sliding gate valves generally consist of a drive, a mechanical part and a refractory part. The slide plate is divided according to the number of slide plates forming the slide gate system and can be divided into a two-layer type and a three-layer type. Three laminar slide gate valves, it is fixed with the upper nozzle to go up the slide during operation, and lower slide is fixed with lower nozzle, dams and throttle through middle slide.
The lower nozzle is easy to generate transverse cracks in the steel casting process, and potential safety hazards are brought to continuous casting operation. The external force applied to the drain is another important cause of breakage. In the process that the ladle runs through the ladle car, because the sliding nozzle mechanism is located at the bottom of the ladle, the lower nozzle at the lowest part of the sliding nozzle mechanism is closest to the running ground of the ladle, if an obstacle exists on a running path, the sliding nozzle mechanism is easy to collide with the lower nozzle, so that the lower nozzle is broken or sealed to lose efficacy, molten steel is easy to leak, the ladle car and other equipment are burnt out, steelmaking production is interrupted, and the consequence is very serious. Therefore, how to prevent the sliding nozzle mechanism from generating abnormal phenomena such as the fracture of the lower nozzle, the sealing failure and the like caused by accidental collision in the operation process of the ladle and avoid the production accident of molten steel leakage is a difficult problem to be solved by the technical personnel in the field.
The patent with the publication number of CN114985717 is an earlier application of the applicant, and discloses a high-safety anti-collision sliding water gap mechanism, which can play a role in buffering by matching a protection cylinder with an extrusion mechanism, can play a role in buffering by extruding hydraulic oil in a cylinder barrel by using collision impact force, can detect the rotating direction of the protection cylinder after being collided through a rotating direction detector, further controls the flow direction of a hydraulic reversing pipeline, enables the active rotating direction of the protection cylinder driven by a hydraulic motor to rotate to be consistent with the passive rotating direction of the protection cylinder when being collided, enables the hydraulic motor to drive the protection cylinder to rotate in an accelerated way, enables the protection cylinder to have larger rotating speed and torsion, can get rid of obstacles, and improves the anti-collision effect.
However, in actual use, the applicant finds that, in order to enable the protection cylinder to play a role in protecting the drain, the bottom of the protection cylinder is aligned with the bottom of the drain as much as possible, so that although a good anti-collision effect can be achieved, the drain is prevented from being inserted into a pouring gate of a crystallizer, the drain cannot be fully inserted into the pouring gate, even is not aligned with the pouring gate, molten steel can be poured outside the pouring gate, resource waste is caused, and molten steel splashing can cause injury to workers. There is therefore a need for improvement.

When collision occurs, the rotation of the rotary ring disc 12 can drive the scroll spring 62 to deform and store energy, so that the buffering performance of preventing false collision is further improved, and after the collision is finished, the rotary ring disc 12 can automatically reset under the action of the elastic restoring force of the scroll spring 62, so that the hydraulic reversing pipeline 33 and the active oil inlet and outlet pipeline 58 are prevented from being wound on the heat insulation sleeve 5 due to the random rotation of the rotary ring disc 12;
in this embodiment, in order to further improve the crash cushion performance, the oil discharge port 19 is provided in a tapered shape, and the size of the opening 4 of the oil discharge port 19 facing the inside of the cylinder tube 14 is larger than the size of the opening 4 facing away from the inside of the cylinder tube 14. The oil discharge port 19 is used as a damping hole, so that a throttling effect is achieved, and part of impact energy can be absorbed and converted into heat energy of oil through the oil discharge port 19 and dissipated, so that the buffering effect is improved.
In this embodiment, in order to avoid the striking, sealing piston 15 velocity of motion is too fast and hydraulic oil in cylinder 14 has been clapped directly, lead to the oil extraction speed too fast and the poor condition of buffering effect takes place, be fixed with bumping post 63 on sealing piston 15 towards the terminal surface of oil drain port 19, bumping post 63 is the round platform type, the maximum diameter of bumping post 63 is less than the internal diameter of oil drain port 19, bumping post 63 is used for cooperating with oil drain port 19, bumping post 63 gets into in the oil drain port 19 with the flow that reduces oil drain port 19 when sealing piston 15 is close oil drain port 19.

in the moving process of the ladle and the sliding nozzle mechanism, if an obstacle which is not noticed in advance exists on a moving path, the protective sleeve 28 surrounds the lower nozzle 2 together, so that the lower nozzle 2 can be prevented from being impacted, and the steel leakage accident can be avoided;
when an obstacle collides with the protective sleeve 28, the protective sleeve 28 moves inwards under stress, the connecting rod 29 drives the piston rod 16 to move, the piston rod 16 drives the sealing piston 15 to move in the cylinder 14, hydraulic oil in the cylinder 14 is extruded to the outer annular cavity 7 through the oil outlet 19, the first electromagnetic valve 10 is in a normally open state, the hydraulic oil in the outer annular cavity 7 flows into the inner annular cavity 8 through the hydraulic oil conducting pipe 9, the annular piston 60 descends, and the second pressure spring 61 compresses to play a primary buffering role;
because the protection mechanism 21 is installed on the rotatable rotating ring disc 12, the protection sleeve 28 generally does not move only inwards when being impacted, but is affected by the impacting position to drive the rotating ring disc 12 to rotate; if it is assumed that the impact point is at the protective sleeve 28 on the lower left portion in a top view, the rotating ring 12 tends to rotate counterclockwise, the rotating ring 12 can be directly detected to rotate counterclockwise by the rotation direction detector 31, after the control system 34 obtains the rotation direction information of the rotating ring 12, the two-position four-way directional valve 53 is controlled to open a matched directional passage, and at the same time, the first electromagnetic valve 10 is controlled to close, so that the hydraulic oil conducting pipe 9 is opened, the second electromagnetic valve 54 is opened, the hydraulic oil in the outer ring cavity 7 flows to the hydraulic motor 32 through the hydraulic directional pipeline 33, so that the active rotational direction of the rotating ring 12 driven by the hydraulic motor 32 is consistent with the passive rotational direction of the rotating ring 12 when the protective sleeve 28 is impacted, thereby increasing the rotating speed of the rotating ring 12, and the rotating ring 12 drives the first gear 24 and the first rotating shaft 23 to rotate by the acceleration transmission mechanism 35, the first rotating shaft 23 drives the second rotating shafts 27 and the protective sleeve 28 to rotate at an accelerated speed through the universal coupling 26, thereby increasing the kinetic energy of the protective sleeve 28 to the protective sleeve 28 and the protective sleeve 28, thereby increasing the self-rotating speed of the protective sleeve 28 and the obstacle throwing effect to the obstacle;
when the oil pipe is impacted, the rotary ring disc 12 rotates to drive the volute spring 62 to deform and store energy, and after the impact is finished, the rotary ring disc 12 resets under the action of the elastic restoring force of the volute spring 62, so that the hydraulic reversing pipeline 33 and the active oil inlet and outlet pipeline 58 are prevented from winding the heat insulation sleeve 5;
when pouring is needed, the water outlet 2 moves to a pouring gate, the third electromagnetic valve 59 is controlled to be opened, the first electromagnetic valve 10 is controlled to be closed, hydraulic oil is introduced into the active oil inlet and outlet pipeline 58 and the outer annular cavity 7 through an external hydraulic station, the sealing piston 15 is further pushed to move outwards, the first pressure spring 17 is compressed, the piston rod 16 pushes the movable mounting plate 25 and the second rotating shaft 27 to move outwards through the connecting rod 29, so that the protective sleeve piece 28 is rotated upwards to be far away from the water outlet 2, and after the protective sleeve piece 28 is rotated upwards to a top dead point, the third electromagnetic valve 59 is closed, so that the water outlet 2 can be conveniently and accurately moved to the pouring gate and enters the pouring gate to be poured;
after pouring is finished, the third electromagnetic valve 59 is controlled to be opened, the sealing piston 15 moves inwards under the action of the elastic restoring force of the first pressure spring 17 and the gravity of the protecting sleeve 28 until the protecting sleeve 28 restores to a vertical posture, at the moment, the first pressure spring 17 is in a natural state, a buffering gap is reserved between the sealing piston 15 and the cylinder 14, and hydraulic oil required for buffering is filled in the buffering gap to provide buffering for collision.
