Description

Technical Field

[0001] The utility model relates to the technical field of large coil production, in particular to a cooling device for a large coil rotary guide. Background Art

[0002] Large coils are hot-rolled steel coils with skins produced by steel mills. They are a key raw material for a wide range of steel products, widely used in the automotive, machinery, and construction industries. The rotating guide for large coils, located above the coiler, feeds the rolled product into the coiler. During the large coil production process, the rotating guide is cooled with cooling water.

[0003] The existing cooling system requires operators to manually open the valve, and the cooling water is kept in a continuous flow state during the large coil production process. When the rotating guide is lowered to discharge steel, a large amount of cooling water will flow into the coil collection drum along the rotating guide, causing water to enter the reduction gear box inside the coil collection drum. Utility Model Content

[0014] By means of the above solution, the beneficial effects of the present invention are as follows:

[0015] 1. The present invention utilizes an inverted U-shaped cooling water pipe to evenly spray cool the rotating guide body as it rises into position. By providing a proximity switch, a PLC cabinet, and an electro-pneumatic valve, when the rotating guide body rises into position, the proximity switch receives a signal and, through the PLC cabinet and electro-pneumatic valve, controls the cooling water flow, which then evenly sprays the rotating guide body for cooling. When the rotating guide body descends, the proximity switch loses its signal, and the PLC cabinet and electro-pneumatic valve control the cooling water flow off, effectively preventing cooling water from flowing along the rotating guide body into the reel drum as the rotating guide body descends for steelmaking.

[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] See also Figure 1-9The utility model provides a cooling device for a large coiled rotary guide, comprising a rotary guide body 1, the rotary guide body 1 being rotatably connected to one side of a support base 2, a water collecting trough 3 being provided below the rotary guide body 1, an inverted U-shaped cooling water pipe 4 being provided on the upper outer side of the rotary guide body 1, and the inverted U-shaped cooling water pipe 4 being located just above the water collecting trough 3, the two vertical sides of the inverted U-shaped cooling water pipe 4 being respectively located on the left and right sides of the rotary guide body 1, and the inverted U-shaped cooling water pipe 4 being close to the rotary guide body 1. Multiple groups of nozzles 41 are installed on one side, and the upper end of the inverted U-shaped cooling water pipe 4 is connected to the water inlet pipe 5, which is fixedly connected to the front side of the platform 100. The water inlet pipe 5 is fixedly connected to an electric-controlled pneumatic valve 6. Baffles 7 are symmetrically fixedly connected to the outside of the two vertical sides of the inverted U-shaped cooling water pipe 4. A proximity switch 11 is fixedly connected to the support seat 2. The rise and fall of the rotating guide body 1 is received by the proximity switch 11 and transmitted to the PLC cabinet. The PLC cabinet and the electric-controlled pneumatic valve 6 are electrically connected.

[0030] The present invention achieves the function of uniformly spraying cooling on the rotating guide body 1 as it rises into position by providing an inverted U-shaped cooling water pipe 4. By providing a proximity switch 11, a PLC cabinet, and an electrically controlled pneumatic valve 6, when the rotating guide body 1 rises into position, the proximity switch 11 receives a signal and controls the cooling water to be turned on via the PLC cabinet and the electrically controlled pneumatic valve 6. The cooling water then uniformly sprays cooling on the rotating guide body 1. When the rotating guide body 1 descends, the proximity switch 11 loses its signal and controls the cooling water to be turned off via the PLC cabinet and the electrically controlled pneumatic valve 6. This effectively prevents the cooling water from flowing along the rotating guide body 1 into the reel drum as the rotating guide body 1 descends for steelmaking.

[0031] Specifically, the inverted U-shaped cooling water pipe 4 covers the left, right, and top sides of the rotating guide body 1, maximizing the cooling range and ensuring uniform distribution of the cooling water without affecting the movement of the rotating guide body 1. Furthermore, the baffle 7 not only prevents splashing of cooling water during spraying but also directs it into the sump 3.

[0032] It should be noted that the water collecting tank 3 is connected to the drainage system, and the water inlet pipe 5 is connected to an external cooling water source, thereby ensuring a continuous supply of cooling water and smooth drainage of the water collecting tank 3.

[0033] Working principle: When the rotating guide body 1 rises to the specified position, the proximity switch 11 receives the signal and transmits the signal to the PLC cabinet. The PLC cabinet then controls the electric-controlled pneumatic valve 6 to open. At this time, the cooling water in the water inlet pipe 5 is sprayed out from the nozzle 41 through the inverted U-shaped cooling water pipe 4, and the rotating guide body 1 is evenly sprayed and cooled. At this time, a small amount of cooling water evaporates due to the high temperature baking of the rotating guide body 1, and the remaining cooling water will flow into the water collection tank 3. When the rotating guide body 1 begins to descend, the proximity switch 11 signal is lost and the lost signal is transmitted to the PLC cabinet again. The PLC cabinet then controls the electric-controlled pneumatic valve 6 to close. At this time, the cooling water stops spraying, thereby avoiding the situation where the cooling water flows into the collection drum along the rotating guide body 1.

[0034] Furthermore, the distance between each two adjacent groups of nozzles 41 is 200 mm to 300 mm.

[0035] Specifically, the spacing between two adjacent groups of nozzles 41 should be neither too large nor too small; an appropriate distance, preferably 200 mm to 300 mm, should be used. This not only ensures uniformity and coverage of the spray, but also helps improve the efficiency of cooling water use. If the spacing is too large, some areas of the rotating guide body 1 will not receive adequate spray coverage, thereby affecting the overall cooling effect. If the spacing is too small, cooling water will be wasted.

[0036] Furthermore, the baffle 7 is a C-shaped arc-shaped plate, and the opening of the baffle 7 faces the rotating guide body 1 .

[0037] Specifically, the C-shaped arc plate can effectively block and guide the cooling water, thereby preventing the water from splashing.

[0038] Furthermore, a plurality of groups of vertical ribs 71 are fixedly connected at equal intervals to one side of the baffle 7 close to the rotating guide body 1 .

[0039] Specifically, the vertical ribs 71 can guide the splashing cooling water, thereby guiding the cooling water along the vertical ribs 71 into the water collection trough 3, thereby preventing the water droplets from forming water beads on the baffle 7. At the same time, the vertical ribs 71 also increase the contact area between the water droplets and the baffle 7, helping the water droplets to flow down the surface of the baffle 7 more quickly and reducing the splashing of water droplets due to unstable sliding of the smooth surface of the baffle 7.

[0040] Furthermore, the baffle 7 and the inverted U-shaped cooling water pipe 4 are fixed with screws using a C-shaped buckle 72 .

[0041] Specifically, the baffle 7 is fixed to one side of the inverted U-shaped cooling water pipe 4 by a C-shaped buckle 72, which is convenient for subsequent disassembly and maintenance.

[0042] Furthermore, the front side of the platform 100 is fixedly connected to a right-angle frame 8 for supporting the inverted U-shaped cooling water pipe 4, the inner side of the right angle of the right-angle frame 8 is fixedly connected to a diagonal brace 81, and the front end of the horizontal side of the right-angle frame 8 is fixedly connected to a U-shaped seat 82 for fixing the inverted U-shaped cooling water pipe 4.

[0043] Specifically, the right-angle bracket 8 can provide auxiliary support for the inverted U-shaped cooling water pipe 4 to ensure its stable position.

[0044] Furthermore, a square plate 9 is fixedly connected to the rear side of the upper surface of the rotating guide body 1, and a fixing frame 10 for fixing the proximity switch 11 is connected to the upper surface of the support seat 2 by bolts. When the rotating guide body 1 rises into place, the square plate 9 is located directly to the left of the proximity switch 11.

[0045] Specifically, when the rotating guide body 1 rises to its full height, the square plate 9 is located just to the left of the proximity switch 11. At this point, the proximity switch 11 receives a signal and transmits it to the PLC cabinet, thereby controlling the electric-pneumatic valve 6 to open and the cooling water begins to flow out. When the rotating guide body 1 begins to descend, the square plate 9 gradually moves away from the position just to the left of the proximity switch 11. At this point, the proximity switch 11 loses its signal and transmits it to the PLC cabinet, thereby controlling the electric-pneumatic valve 6 to close and the cooling water stops flowing out.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
