Description

Technical Field

[0001] This utility model relates to the field of billet continuous casting technology, specifically a quick adjustment device for water jet strips in a billet continuous casting machine. Background Technology

[0002] A billet continuous casting machine is a type of continuous casting equipment specifically designed for producing square billets. A square billet is a type of steel billet with a cross-section where the width and height are equal or similar, primarily used for rolling structural steel and wire rod. The billet continuous casting machine plays a crucial role in steel production, not only improving production efficiency but also enhancing billet quality. The rapid adjustment device for the water spray strips in a billet continuous casting machine is a technical device used in the steel metallurgical equipment field. Its main function is to rapidly adjust the water spray strips during the billet continuous casting process. The water spray strips primarily function to spray water onto the billet through nozzles, achieving rapid cooling of the high-temperature billet, which is crucial for controlling billet solidification and quality.

[0003] However, the existing quick adjustment device for water jet strips in billet continuous casting machines has the following disadvantages:

[0004] (1) The existing water spray bar adjustment device for billet continuous casting machine has a weak rapid adjustment function. When using it, the billet continuous casting machine needs to cast billets of different specifications. However, the water spray bar for cooling the billet is not easy to adjust according to the height of the billet, resulting in a low cooling effect on the billet.

[0005] (2) The existing water spray bar adjustment device of the billet continuous casting machine has a weak function of easy replacement of nozzles. When in use, the nozzles connected to the water spray bar are prone to blockage or damage after long-term use. At this time, the nozzles need to be replaced. However, the replacement of the nozzles on the existing water spray bar is more troublesome, which makes it difficult to replace the nozzles. Utility Model Content

[0006] The purpose of this invention is to provide a quick adjustment device for the water jet strip of a billet continuous casting machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A quick adjustment device for water spray strips in a billet continuous casting machine includes a support frame. A positioning rod is fixedly installed inside the support frame. Several guide rails are provided on the positioning rod. A servo motor is fixedly installed on the top of the support frame. A bidirectional threaded rod is fixedly connected to the rotating shaft of the servo motor. Both ends of the outer surface of the bidirectional threaded rod are threaded with guide rods. Several water spray strips are arranged between the two sets of guide rods.

[0009] Preferably, the top of the spray bar is provided with a plurality of connecting pipes, the top of the connecting pipes is threadedly connected to a straight nozzle, a sealing ring is provided between the straight nozzle and the connecting pipe, and a spray shell is provided on the top of the straight nozzle.

[0010] Preferably, the inner wall of the support frame is provided with a sliding groove, and both sides of the guide rod are slidably connected inside the sliding groove.

[0011] Preferably, the guide rod has a first water inlet on its front side, and the guide rod and the spray bar are internally connected.

[0012] Preferably, the positioning rod is provided with a diverting rod on both the front and back sides, and the top of the diverting rod is provided with a plurality of connecting pipes, and the top of the connecting pipes is threaded with an L-shaped nozzle.

[0013] Preferably, a second water inlet is provided on one side of the diverting rod, and the L-shaped nozzles connected to the two sets of diverting rods are arranged opposite each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A quick adjustment device for water spray bars in a billet continuous casting machine, through the setting of a servo motor, a guide rod, and a bidirectional threaded rod, when the billet specifications are different, the servo motor is activated, the servo motor drives the bidirectional threaded rod to rotate, and when the bidirectional threaded rod rotates, the guide rod drives the water spray bar to move, thereby controlling the distance between the water spray bar and the billet, thus achieving the function of quickly adjusting the water spray bar and improving the applicability of the water spray bar.

[0016] 2. This quick adjustment device for water jet strips in a billet continuous casting machine, through the arrangement of a connecting pipe, a straight nozzle, and a sealing ring, allows for easy replacement of the straight nozzle during use. When the straight nozzle needs to be replaced, the water jet housing connected to the straight nozzle is rotated, causing the water jet housing to drive the straight nozzle to rotate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0027] A quick adjustment device for water spray strips in a billet continuous casting machine includes a support frame 1. A positioning rod 2 is fixedly installed inside the support frame 1. Several guide rails 3 are provided on the positioning rod 2. A servo motor 4 is fixedly installed on the top of the support frame 1. A bidirectional threaded rod 5 is fixedly connected to the rotating shaft of the servo motor 4. Both ends of the outer surface of the bidirectional threaded rod 5 are threadedly connected to guide rods 6. Several water spray strips 7 are provided between the two sets of guide rods 6.

[0028] Specifically, the support frame 1 supports components such as the positioning rod 2, guide rail 3, and water spray strip 7. When the billet requiring cooling passes through the guide rail 3, the water source connected to the external water pump enters the guide rod 6 and the diverting rod 13 respectively. The water spray strip 7 connected to the guide rod 6 enters several connecting pipes 8 set on the water spray strip 7, and then is sprayed out through the straight nozzle 9 to cool the billet. When the billet specifications are different, the servo motor 4 is activated. The servo motor 4 drives the bidirectional threaded rod 5 to rotate. When the bidirectional threaded rod 5 rotates, the guide rod 6 drives the water spray strip 7 to move, thereby controlling the distance between the water spray strip 7 and the billet, thus achieving the function of quickly adjusting the water spray strip 7 and improving the applicability of the water spray strip 7.

[0029] In this embodiment, preferably, the top of the water spray strip 7 is provided with a plurality of connecting pipes 8, the top of the connecting pipes 8 is threadedly connected to a straight nozzle 9, a sealing ring 10 is provided between the straight nozzle 9 and the connecting pipes 8, and a water spray shell 11 is provided on the top of the straight nozzle 9.

[0030] Specifically, during use, when the straight nozzle 9 needs to be replaced, the spray housing 11 connected to the straight nozzle 9 is rotated, causing the spray housing 11 to drive the straight nozzle 9 to rotate. Through the threaded connection between the straight nozzle 9 and the connecting pipe 8, the straight nozzle 9 disengages from the connecting pipe 8 when it rotates. Subsequently, another straight nozzle 9 and the spray housing 11 are rotatably connected to the connecting pipe 8, so that the top of the connecting pipe 8 abuts against the sealing ring 10, sealing the connection between the connecting pipe 8 and the straight nozzle 9, thereby achieving the purpose of replacing the straight nozzle 9.

[0031] In this embodiment, preferably, the inner sidewall of the support frame 1 is provided with a groove 12, and both sides of the guide rod 6 are slidably connected to the inside of the groove 12.

[0032] Specifically, when the servo motor 4 is running, the bidirectional threaded rod 5 rotates, causing the guide rod 6 to move up and down. As the guide rod 6 moves up and down, the guide rod 6 moves more smoothly by sliding its two ends in the slide groove 12.

[0033] In this embodiment, preferably, the front of the guide rod 6 is provided with a first water inlet 15, and the guide rod 6 and the spray bar 7 are interconnected.

[0034] Specifically, a water source is connected to the first water inlet 15, and water is sprayed out through the guide rod 6 and the spray bar 7, through the connecting pipe 8 and the straight nozzle 9, to cool the billet.

[0035] In this embodiment, preferably, the front and back of the positioning rod 2 are provided with diverting rods 13, the top of the diverting rod 13 is provided with several connecting pipes 8, and the top of the connecting pipes 8 is threadedly connected with an L-shaped nozzle 14.

[0036] Specifically, water is sprayed out through the connecting pipe 8 and L-shaped nozzle 14 on the two-way flow pipe to cool both sides of the billet. Similar to the straight nozzle 9, the top of the L-shaped nozzle 14 is fixedly connected to the water spray shell 11 and is also equipped with a sealing ring 10. Rotating the water spray shell 11 on the L-shaped nozzle 14 causes the L-shaped nozzle 14 to rotate with the rotation of the water spray shell 11, thus disengaging the L-shaped nozzle 14 from the connecting pipe 8 on the flow pipe.

[0037] In this embodiment, preferably, a second water inlet 16 is provided on one side of the diversion rod 13, and the L-shaped nozzles 14 connected to the two diversion rods 13 are arranged opposite to each other.

[0038] Specifically, during use, an external water source enters the two-component flow bar 13 through the second water inlet 16, and is sprayed out through the connecting pipe 8 set on the two-component flow bar 13 into the L-shaped nozzle 14. The L-shaped nozzles 14 on the two-component flow bar 13 are arranged opposite each other to cool the two sides of the billet.

[0039] In this embodiment, a quick adjustment device for the water spray bar 7 of a billet continuous casting machine is used. When the billet requiring cooling passes through the guide rail 3, water from an external water pump enters the guide rod 6 and the diverting rod 13. Water then flows through the water spray bar 7 connected to the guide rod 6 into several connecting pipes 8 on the water spray bar 7, and is subsequently sprayed out through straight nozzles 9 to cool the billet. When the billet specifications are different, the servo motor 4 is activated, driving the bidirectional threaded rod 5 to rotate. As the bidirectional threaded rod 5 rotates, the guide rod 6 moves the water spray bar 7, thereby controlling the distance between the water spray bar 7 and the billet, achieving the effect of quickly adjusting the water spray bar 7 and improving its applicability. When the straight nozzle 9 needs to be replaced, the water spray housing 11 connected to the straight nozzle 9 is rotated, causing the water spray housing 11 to move the straight nozzle 9. When nozzle 9 rotates, it disengages from the connecting pipe 8 due to the threaded connection between the straight nozzle 9 and the connecting pipe 8. Then, another straight nozzle 9 and spray housing 11 are rotatably connected to the connecting pipe 8, so that the top of the connecting pipe 8 abuts against the bottom of the sealing ring 10, thus achieving the function of replacing the straight nozzle 9. When L-shaped nozzle 14 needs to be replaced, the spray housing 11 connected to L-shaped nozzle 14 is rotated, causing the spray housing 11 to drive L-shaped nozzle 14 to rotate. Through the threaded connection between L-shaped nozzle 14 and the connecting pipe 8, it disengages from the connecting pipe 8 when it rotates. Then, another L-shaped nozzle 14 and spray housing 11 are rotatably connected to the connecting pipe 8, so that the top of the connecting pipe 8 abuts against the bottom of the sealing ring 10, thus achieving the function of replacing the straight nozzle 9.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
