[0031] Please see Figures 1-6 This application provides an H-beam rolling mill cooling device 10 for cooling H-beam rolling mill 30, the H-beam rolling mill 30 including a web 31 and two flanges 32 disposed on both sides of the web 31. The H-beam rolling mill cooling device 10 provided in this application embodiment can improve the cooling uniformity of the H-beam rolling mill 30.

[0032] Please see Figure 1 In this embodiment, the H-beam rolling mill cooling device 10 includes a limiting member 100, a first cooling mechanism 200, a support base 300, and a second cooling mechanism 400. The first cooling mechanism 200 is installed on the limiting member 100, which is disposed on the working roller conveyor 20. The H-beam rolling mill 30 is installed inside the limiting member 100. The first cooling mechanism 200 is used to spray water onto the two flanges 32. The support base 300 is disposed below the working roller conveyor 20. The second cooling mechanism 400 is installed on the support base 300. The second cooling mechanism 400 is used to spray water onto the upper and lower surfaces of the web 31, and the second cooling mechanism 400 can slide relative to the support base 300 along the length direction of the working roller conveyor 20.

[0033] The working roller conveyor 20 is located after the H-beam steel production line mill. The working roller conveyor 20 includes multiple working rollers spaced apart. Each working roller is equipped with a motor to drive its rotation in order to convey the rolled workpiece. The conveying direction of the working roller conveyor 20 is perpendicular to the length direction of the working roller conveyor 20. The structure and principle of the working roller conveyor 20 are existing technologies and will not be described in detail here.

[0034] A limiting member 100 is disposed on the working roller conveyor 20. An H-beam rolled piece 30 is installed within the limiting member 100, and portions of multiple working rollers extend into the limiting member 100 and contact the H-beam rolled piece 30. Therefore, the multiple working rollers can transport the H-beam rolled piece 30 by rotation. The H-beam rolled piece 30 is placed horizontally within the limiting member 100, i.e., the web 31 is parallel to the ground, and the two flanges 32 are located at opposite ends of the web 31. For ease of description, the working roller conveyor 20 is defined as transporting the H-beam rolled piece 30 in a front-to-back direction, with the two flanges 32 located at the left and right ends of the web 31, respectively.

[0035] The first cooling mechanism 200 and the second cooling mechanism 400 can spray water to cool the rolled piece. Since the first cooling mechanism 200 is used to spray water on the two flanges 32 and the second cooling mechanism 400 is used to spray water on the upper and lower surfaces of the web 31, that is, the first cooling mechanism 200 and the second cooling mechanism respectively spray water to cool the flanges 32 and the web 31 of the H-beam rolled piece 30, the cooling uniformity of the H-beam rolled piece 30 can be improved.

[0036] Furthermore, the working roller conveyor 20 can drive the H-beam steel roll 30 to move relative to the second cooling mechanism 400 along the conveying direction of the working roller conveyor 20, and the second cooling mechanism 400 can slide relative to the support seat 300 along the length direction of the working roller conveyor 20. That is, the second cooling mechanism 400 and the H-beam steel roll 30 can move in the front, back, left and right directions, so that the second cooling mechanism 400 can be moved to the position of the web 31 to be cooled as needed, further improving the cooling uniformity of the H-beam steel roll 30.

[0037] Of course, when the working roller conveyor 20 drives the H-beam steel roll 30 to move along the conveying direction of the working roller conveyor 20, the H-beam steel roll 30 also moves relative to the limiting member, and thus moves relative to the first cooling mechanism 200, so that all parts of the flange 32 can be sprayed with water by the first cooling mechanism 200 as much as possible, thereby improving the cooling uniformity of the flange 32.

[0038] Please see Figures 2-4 In some embodiments, the limiting member 100 includes a base plate 110 and two side plates 120. The base plate 110 contacts the working roller conveyor 20, and the two side plates 120 are respectively disposed on both sides of the base plate 110 along the length direction of the working roller conveyor 20. The H-beam steel roll 30 is disposed on the base plate 110. The first cooling mechanism 200 includes two first water spraying assemblies 210, which are respectively disposed on the two side plates 120.

[0039] Two side plates 120 are respectively disposed on the left and right sides of the base plate 110. The side plate 120 on the left corresponds to the flange 32 on the left end, and the side plate 120 on the right corresponds to the flange 32 on the right end. The two flanges 32 are in contact with the working roller conveyor 20, and there is a gap between the web plate 31 and the base plate 110. Since the two first water spray assemblies 210 are disposed on the two side plates 120, each first water spray assembly 210 is used to spray water to cool the flange 32 on the same side. In other words, each flange 32 is provided with a corresponding first water spray assembly 210, thereby improving the uniformity of cooling of the flanges 32.

[0040] Specifically, the bottom plate 110 can be arranged parallel to the web plate 31, and the flange 32 can be arranged parallel to the side plate 120 on the same side, that is, the side plate 120 is perpendicular to the bottom plate 110.

[0041] Please see Figure 2 and Figure 3 In some embodiments, both first water spraying assemblies 210 include a first water pipe 211 and a plurality of water spraying elements 212 connected to the first water pipe 211. A plurality of first water spraying holes 121 are provided on the side plate 120. The plurality of first water spraying holes 121 are spaced apart on the side plate 120 along the conveying direction of the working roller conveyor 20. The plurality of water spraying elements 212 are arranged in a one-to-one correspondence with the plurality of first water spraying holes 121.

[0042] The first water pipe 211 is used to introduce cooling water, and the water spray element 212 is used to spray out cooling water. Since multiple water spray elements 212 are connected to the first water pipe 211, under the action of water pressure, multiple water spray elements 212 can spray cooling water to the corresponding flange 32 through the corresponding first water spray hole 121 to achieve cooling.

[0043] Multiple first water spray holes 121 are spaced apart on the side plate 120 along the conveying direction of the working roller conveyor 20, which means that multiple water spray elements 212 are spaced apart on the side plate 120 along the conveying direction of the working roller conveyor 20. Since the H-beam rolled piece 30 is relatively long and its length direction is consistent with the conveying direction of the working roller conveyor 20, the multiple water spray elements 212 spaced apart on the side plate 120 along the conveying direction of the working roller conveyor 20 can ensure that every part of the flange 32 can be sprayed with cooling water in the conveying direction of the working roller conveyor 20, thereby improving the cooling uniformity of the flange 32.

[0044] Please see Figures 3-5 In some embodiments, the water spray component 212 includes a mounting part 2121 and a plurality of first nozzles 2122 mounted on the mounting part 2121. The mounting part 2121 is connected to the side plate 120. The plurality of first nozzles 2122 are connected to the first water pipe 211. The plurality of first nozzles 2122 are correspondingly arranged with the first water spray hole 121, and the plurality of first nozzles 2122 are arranged at vertical intervals.

[0045] Mounting part 2121 is used to mount multiple first nozzles 2122, and mounting part 2121 is connected to side plate 120, thereby fixing water spray component 212 on side plate 120. First water pipe 211 can be horizontally set, and the first water pipe 211 is provided with multiple branch pipes 213 corresponding to the multiple water spray components 212. The branch pipes 213 extend into the corresponding mounting part 2121 to communicate with the multiple water spray components 212. Multiple first nozzles 2122 are correspondingly set with first water spray holes 121, that is, multiple first nozzles 2122 are set in the first water spray holes 121, so that the first nozzles 2122 can spray cooling water to the corresponding flange 32 through the corresponding first water spray holes 121. Since multiple first nozzles 2122 are arranged vertically at intervals, that is, in the height direction of flange 32, all parts can be sprayed with cooling water, thereby further improving the cooling uniformity of flange 32.

[0046] Specifically, the first nozzle 2122 may be an adjustable-angle nozzle, which can be adjusted according to the height of the H-beam roll 30 to improve the cooling uniformity of the flange 32.

[0047] Please see Figure 3 In some embodiments, the first cooling mechanism 200 further includes a water inlet pipe 220 and a first connecting pipe 230. The first water pipes 211 of the two first water spray assemblies 210 are connected through the first connecting pipe 230. The water inlet pipe 220 is connected to the first water pipe 211 of one of the first water spray assemblies 210. The water inlet pipe 220 and the first water pipe 211 are arranged at an angle.

[0048] The water inlet pipe 220 is used to introduce cooling water. Since the water inlet pipe 220 is connected to the first water pipe 211 of one of the first water spray components 210, and the first water pipes 211 of the two first water spray components 210 are connected through the first connecting pipe 230, that is, the water inlet pipe 220 is connected to the first water pipes 211 of the two first water spray components 210, so that cooling water can enter the two first water pipes 211 to achieve water spraying.

[0049] Specifically, two first water pipes 211 can be arranged along the conveying direction of the working roller conveyor 20, the first connecting pipe 230 can be arranged at the bottom of the limiting member 100, and the water inlet pipe 220 is arranged perpendicular to the first water pipes 211.

[0050] Of course, in other embodiments, the first water pipes 211 of the two first water spray components 210 may not be connected, and the first water pipes 211 of the two first water spray components 210 may be connected to a water inlet pipe 220 to allow cooling water to be introduced, without limitation.

[0051] Please see Figure 2 and Figure 3 In some embodiments, the second cooling mechanism 400 includes a plurality of second water spraying assemblies 410, and the support base 300 includes a plurality of support portions 310. The plurality of support portions 310 are spaced apart along the conveying direction of the working roller conveyor 20. The plurality of support portions 310 are arranged in a one-to-one correspondence with the plurality of second water spraying assemblies 410, and the second water spraying assemblies 410 are mounted on the corresponding support portions 310.

[0052] Multiple support parts 310 are spaced apart along the conveying direction of the working roller conveyor 20. Each support part 310 is correspondingly arranged with a multiple second water spray assembly 410. The second water spray assembly 410 is installed on the corresponding support part 310. In other words, multiple water spray assemblies are spaced apart along the conveying direction of the working roller conveyor 20. Therefore, in the length direction of the web 31, it can be ensured that all parts can be sprayed with cooling water, thereby improving the cooling uniformity of the web 31.

[0053] In some embodiments, each second water spray assembly 410 includes a second water pipe 411 and a plurality of second nozzles 412 communicating with the second water pipe 411. The second water pipe 411 includes an upper pipe 4111 and a lower pipe 4112. The upper pipe 4111 is located above the limiting member 100, and the lower pipe 4112 is located below the limiting member 100. The lower pipe 4112 is mounted on the support 310. Both the upper pipe 4111 and the lower pipe 4112 are provided with a plurality of second nozzles 412.

[0054] The upper pipe 4111 is located above the limiting member 100, so that multiple second nozzles 412 on the upper pipe 4111 can spray water to cool the upper surface of the web 31. The lower pipe 4112 is located below the limiting member 100, so that multiple second nozzles 412 on the lower pipe 4112 can spray water to cool the lower surface of the web 31. Both the upper pipe 4111 and the lower pipe 4112 are horizontally arranged, and a connecting pipe 4113 connects the upper pipe 4111 and the lower pipe 4112. That is, multiple second nozzles 412 are provided on both the upper and lower surfaces of the web 31 to spray water, thereby improving the cooling uniformity of the web 31.

[0055] Specifically, the second nozzle 412 may also be an adjustable-angle nozzle, which can be adjusted according to the width of the H-beam roll 30 to improve the cooling uniformity of the flange 32.

[0056] Please see Figure 3 and Figure 4 In some embodiments, the limiting member 100 includes a base plate 110 and two side plates 120. The base plate 110 contacts the working roller conveyor 20, and the two side plates 120 are respectively arranged on both sides of the base plate 110 along the length direction of the working roller conveyor 20. The H-beam steel roll 30 is disposed on the base plate 110. The base plate 110 is provided with a plurality of second water spray holes 111, and the plurality of second water spray holes 111 are respectively arranged in correspondence with the lower pipes 4112 of the plurality of second water spray components 410.

[0057] Two side plates 120 are respectively disposed on the left and right sides of the base plate 110. The side plate 120 on the left corresponds to the flange 32 at the left end, and the side plate 120 on the right corresponds to the flange 32 at the right end. Both flanges 32 are in contact with the working roller conveyor 20. The base plate 110 is provided with a plurality of second water spray holes 111. The plurality of second water spray holes 111 are respectively disposed in correspondence with the lower pipes 4112 of the plurality of second water spray assemblies 410. The projection of the second water spray holes 111 on the corresponding lower pipes 4112 covers the plurality of second nozzles 412 on the lower pipes 4112. Thus, the plurality of second nozzles 412 on the lower pipes 4112 can spray water to cool the lower surface of the web 31 through the corresponding second water spray holes 111. Specifically, the plurality of second nozzles 412 on the upper pipes 4111 and the lower pipes 4112 can be spaced apart along the length direction of the working roller conveyor 20 to improve the cooling uniformity of the web 31.

[0058] In some embodiments, the second cooling mechanism 400 further includes a second connecting pipe 420 that connects to a second water pipe 411 of each second water spray assembly 410, wherein the second water pipe 411 of one of the second water spray assemblies 410 has a water inlet 430.

[0059] The inlet 430 is used to introduce cooling water. Since the second water pipe 411 of one of the second water spray components 410 has an inlet 430, the second water pipe 411 of each second water spray component 410 is connected through the second connecting pipe 420, so that the cooling water introduced through the inlet 430 can enter each second water pipe 411.

[0060] Specifically, the second connecting pipe 420 is disposed at the same end of the plurality of lower pipes 4112 and communicates with each of the lower pipes 4112. One of the lower pipes 4112 extends out of the second connecting pipe 420, and the water inlet 430 is disposed at the extension of the lower pipe 4112 to facilitate the introduction of cooling water. An arc-shaped reinforcing rib 440 can be provided between the other ends of each pair of adjacent lower pipes 4112 to enhance the structural strength of the second cooling mechanism 400. Furthermore, since the plurality of second water pipes 411 are spaced apart along the conveying direction of the working roller conveyor 20, a plurality of reinforcing plates 450 can also be provided to connect the plurality of second water pipes 411. Reinforcing plates 450 can be provided on the plurality of upper pipes 4111, the plurality of connecting pipes 4113, and the plurality of lower pipes 4112.

[0061] Please see Figure 6 In some embodiments, the support 310 includes a bracket 311 and a track wheel 312 rotatably disposed on the bracket 311. The outer peripheral surface of the track wheel 312 is provided with a mounting groove 3121, and the lower tube 4112 is movably installed in the mounting groove 3121.

[0062] Since the track wheel 312 is rotatably mounted on the bracket 311, and the lower tube 4112 is movably installed in the mounting groove 3121, the lower tube 4112 can slide relative to the track wheel 312. Specifically, there are two track wheels 312, which are spaced apart along the length of the working roller conveyor 20.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
