Description

Technical Field

[0001] This utility model relates to the technical field of equipment for placing and processing sliders for steelmaking, and specifically to a special tool for placing sliders. Background Technology

[0002] In steelmaking continuous casting, multiple types of slide blocks are used without fixed placement, which can easily lead to misplacement and make handling of the unfinished slide blocks inconvenient. Slide blocks are mainly used in high-temperature, high-wear environments such as heating furnaces and continuous casting equipment in the metallurgical industry. Materials used include silicon nitride ceramics, heat-resistant steel (such as 2848W5, ZG4Cr25Ni20Si2), and cobalt-based alloys (such as Co20, Co50), which possess high-temperature wear resistance and creep resistance. Silicon nitride ceramics have a hardness of 15-17 GPa, retaining over 80% of its hardness at 1200℃, with a wear rate of only 0.2μm / 100 km and a lifespan of 12-18 months. Heat-resistant steel (such as 2848W5) is suitable for rolling mill heating furnaces and pusher-type heating furnaces, capable of withstanding high-temperature billet friction and reducing "water pipe black marks." Cobalt-based alloys (such as Co20 / Co50) are specifically designed for metallurgical heating furnaces, offering high temperature resistance and wear resistance.

[0003] The various types of sliders make handling inconvenient; with eight flow lines, one person needs to make two round trips to retrieve the sliders, and it's easy to place the wrong slider in the wrong flow line. There's also the risk of sliders falling and causing injury or foot damage. Currently, the lower-line sliders are held together with thin oxygen tubing, which is wasteful and inconvenient. Therefore, there is an urgent need for a specialized tool for placing sliders to solve the problems of low efficiency, material waste, and easy misplacement of sliders in the existing manual slider handling process. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a special tool for placing sliders.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a special tool for placing sliders, including an upper tray and a lower tray. The upper tray and the lower tray are each provided with a fixed plate in the middle and folding plates on both sides. The folding plates are movably mounted on the fixed plate. A placement screw is provided on the folding plate, and a placement slider passes through the placement screw.

[0006] Specifically, the bottom of the upper tray is connected to the lower tray, and the bottom of the fixing plates of both the upper and lower trays are provided with threaded sleeves. The threaded sleeves are internally threaded with support screws, which are fixed to the upper part of the fixing plate of the lower tray. The upper tray and at least one lower tray are connected to each other to form a tower-like structure.

[0007] Specifically, the folding plate is provided with threaded holes, and a placement screw is threaded into the threaded holes. The placement screws on the folding plates on both sides of the fixing plate are staggered, and a fastening nut is threaded onto the placement screw. The fastening nut is located at the bottom of the folding plate.

[0008] Specifically, a pad is laid on the folding plate, and a through hole is provided in the middle of the pad. The through hole and the threaded hole are set in the same circle, and a mark indicating the slider model is provided on the pad.

[0009] Specifically, the folding plate is rotatably connected to the fixed plate via an elastic hinge. The elastic hinge is a spring hinge, and a baffle is fixedly installed at the bottom of the folding plate. When the folding plate is unfolded, the baffle blocks the bottom of the fixed plate.

[0010] Specifically, a handle is fixedly installed on the upper part of the fixing plate of the upper tray. The handle includes a support rod and a handle. One end of the support rod is fixedly installed in the middle of the fixing plate of the upper tray, and the other end of the support rod is fixedly connected to the handle.

[0011] This utility model has the following beneficial effects: This utility model designs a special tool for placing sliders, which adopts a multi-layer tray structure design. Multiple sliders can be picked up at once by the handle, which is highly efficient. All sliders are fitted onto the placement screw, and the height of the placement screw can be adjusted to adapt to different models of sliders, making slider placement more stable and safer.

[0012] This invention utilizes a specialized tool for placing sliders, employing a labeled pad to protect the sliders from wear and tear while facilitating their sorting and preventing misplacement. After production, the sliders are easily placed in the waste water inlet storage area, reducing the use of fine oxygen tubing, lowering energy consumption, and saving production costs.

[0017] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] like Figures 1-3 As shown, a special tool for placing sliders includes an upper tray 1 and a lower tray 2. Both the upper tray 1 and the lower tray 2 are provided with a central fixed plate 9 and folding plates 8 on both sides. The folding plates 8 are movably mounted on the fixed plate 9.

[0019] The bottom of the upper tray 1 is connected to the lower tray 2. The bottom of the fixing plates of the upper tray 1 and the lower tray 2 are provided with threaded sleeves 4. The threaded sleeves 4 are internally threaded to support screws 5. The support screws 5 are fixed on the upper part of the fixing plate 9 of the lower tray 2. The upper tray 1 and the two lower trays 2 are connected to each other to form a tower-like structure.

[0020] A placement screw 6 is provided on the folding plate 8, and a threaded hole 7 is provided on the folding plate 8. The placement screw 6 is internally connected to the threaded hole 7. The placement screws 6 on the folding plates 8 on both sides of the fixing plate 9 are staggered to prevent them from colliding with each other when the folding plate 8 is folded up. The entire tray is more compact when folded up, occupies less space, and is easier to place. The folded state of the folding plate 8 does not affect the sliding block of the lower tray 2, making operation more convenient.

[0021] A fastening nut 13 is threaded onto the placement screw 6. The fastening nut 13 is located at the bottom of the folding plate 8. The fastening nut 13 fixes the placement screw 6 and prevents the placement screw 6 from slipping. An installation hole is provided in the middle of the slider, and the placement screw 6 passes through the installation hole of the slider.

[0022] A pad 12 is laid on the folding plate 8. The pad 12 has a through hole in the center, which is concentric with the threaded hole 7. The pad 12 is marked with the slider model number. The pad 12 can protect the slider from wear and tear, and also facilitate the classification of sliders, making it less likely to misplace them.

[0023] The folding plate 8 is rotatably connected to the fixed plate 9 via a flexible hinge 10. The flexible hinge 10 is a spring hinge, and the spring preload of the flexible hinge 10 controls the folding plate 8 to be in the folded state. After the slider is placed on the placement screw 6, the folding plate 8 is pressed into a flat state. A baffle 11 is fixedly installed at the bottom of the folding plate 8. When the folding plate 8 is unfolded into a flat state, the baffle 11 blocks the bottom of the fixed plate 9, and the baffle 11 forms a limiting plate structure.

[0024] A handle 3 is fixedly installed on the upper part of the fixing plate 9 of the upper tray 1. The handle 3 includes a support rod and a handle. One end of the support rod is fixedly installed in the middle of the fixing plate 9 of the upper tray 1, and the other end of the support rod is fixedly connected to the handle.

[0025] The working principle of this utility model is as follows: the number of tray layers required is determined according to the amount of flow formed by the sliders to be picked up and placed. The height of the placement screw 6 is adjusted according to the size of the sliders and fixed by the fastening nut 13. First, the sliders are placed in place layer by layer according to the model marking of the pad 12, and then lifted out by the handle 3.

[0026] In this invention, each tray has eight sliders that can be completely removed in one go, and it is easy to distinguish the number and type of sliders for each flow.

[0027] The sliding block after the line is easily placed in the waste water inlet storage area, reducing the use of fine oxygen tubes. If the water inlet is replaced 3 times a day, and 6 fine oxygen tubes are saved, 0.8 tons of fine oxygen tubes can be saved per year. At 4,500 yuan per ton, this amounts to a saving of 3,600 yuan.

[0028] This utility model is not limited to the above-described embodiments. Anyone should know that any structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
