Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting, in particular to a tundish tilting device. Background Art

[0002] The tundish tilting device is an important part of the equipment in the maintenance area of ​​the continuous casting machine. As a buffer between the ladle and the crystallizer, the tundish can promote the floating of inclusions in the molten steel. It can also perform certain tundish metallurgy to even out the composition and temperature of the molten steel and realize multi-furnace continuous casting. Due to the long-term high temperature of the molten steel, refractory materials will be laid inside the tundish. Refractory materials have a service life and need to be replaced regularly. When replacing the refractory materials in the tundish, it is necessary to fix the tundish on the tundish tilting device, and pour out the refractory materials in the tundish through the tilting action of the tundish tilting device, so as to prepare for the subsequent laying of new refractory materials in the tundish.

[0003] When steel mills build new continuous casting machines, they usually build them in or near existing plants. The biggest problem they face is insufficient plant space.

[0004] At present, the most commonly used intermediate tank tilting device can only fix one type of intermediate tank on one side of the tilting frame and complete the tilting action. The most obvious disadvantage is that each intermediate tank is used for a specific purpose, and each intermediate tank must have a corresponding intermediate tank tilting device, which not only increases the construction cost but also occupies the plant space.

[0005] There is also an intermediate tank tipping device. In order to solve the problem of special tanks for special purposes, the tipping frame of the intermediate tank tipping device will be designed with an additional set of transition frames. When tipping one type of intermediate tank, the transition frame is fixed to the tipping frame, and then the intermediate tank is fixed to the transition frame. When tipping another intermediate tank, the transition frame must be disassembled and placed somewhere else, and then the intermediate tank is fixed to the tipping frame. Although this intermediate tank tipping device solves the problem of special tanks for special purposes, the transition frame still needs to be stored after being disassembled, which fails to save factory space. Moreover, the transition frame must be disassembled and assembled every time a different intermediate tank is tipped, which increases the workload of on-site staff. Utility Model Content

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0036] like Figures 1 to 8 As shown, this embodiment provides an intermediate tank tilting device for tilting the intermediate tank 4, wherein the intermediate tank 4 comprises a tank body 41 and two sets of shaft structures symmetrically arranged at both ends of the tank body 41, each set of shaft structures comprises two ear shafts 42 arranged in parallel and spaced apart, and the intermediate tank tilting device comprises a tilting frame 1 and a driving device, wherein the driving device is connected to the tilting frame 1 and can drive the tilting frame 1 to rotate.

[0037] The tilting frame 1 includes a connecting frame 11 and two groups of positioning structures 12 arranged on both sides of the connecting frame 11 and arranged in opposite directions (when the connecting frame 11 is placed horizontally, the two groups of positioning structures 12 are respectively located above and below the connecting frame 11), each group of positioning structures 12 includes two positioning seats 121 arranged at intervals along the rotation axis direction of the tilting frame 1, and the intervals between the two positioning seats 121 in the two groups of positioning structures 12 are different; a guide block 122 is provided on the top surface of each positioning seat 121, and two horizontal limiting plates 123 are symmetrically provided on the top surface of the positioning seat 121 and on both sides of the guide block 122, and a locking structure 13 that can be horizontally retracted is provided on the top of the guide block 122; the tank body 41 can be placed between the two positioning seats 121, the two ear shafts 42 in each group of shaft structures can be clamped on both sides of the guide block 122, and the horizontal limiting plates 123 can horizontally limit the ear shaft 42 along its axial direction, and the locking structure 13 can extend and press on the top surface of the tank body 41.

[0038] The device can tip over intermediate tanks 4 of two different sizes and specifications, and is mainly suitable for intermediate tanks 4 having two trunnions 42 at the ends, the axial direction of the trunnions 42 being perpendicular to the end surface of the tank body 41. The interval between the two positioning seats 121 in one set of positioning structures 12 matches the length of the tank body 41 of the first size and specifications, and the interval between the two positioning seats 121 in the other set of positioning structures 12 matches the length of the tank body 41 of the second size and specifications.

[0039] Here, the top of the guide block 122 refers to the end away from the positioning seat 121. The width of the guide block 122 along the direction perpendicular to the rotation axis of the tilting frame 1 should match the spacing between the two ear shafts 42 in the shaft structure, and be slightly larger than the spacing between the two ear shafts 42. The horizontal limit plate 123 should be set close to the outer edge of the positioning seat 121 (i.e., the side of the top surface of the positioning seat 121 away from the other positioning seat 121 along the rotation axis of the tilting frame 1). The two horizontal limit plates 123 on the same side of the guide block 122 in the two positioning seats 121 are arranged oppositely, and the spacing between the two should match the distance between the ends of the two coaxial ear shafts 42 at both ends of the tank body 41, and be slightly larger than the distance between the ends of the two ear shafts 42. The height of the position of the locking structure 13 from the top surface of the positioning seat 121 should ensure that the slider 132 can basically press on the top surface of the tank body 41 after being extended.

[0040] When the intermediate tank 4 of the first specification needs to be tipped, the corresponding positioning structure 12 is facing upward. The tank body 41 of the intermediate tank 4 is placed between the two positioning seats 121, and the two ear shafts 42 at the ends of the tank body 41 slide down along the two sides of the guide block 122 and are clamped on the two sides of the guide block 122. At the same time, the ends of the ear shafts 42 basically abut against the horizontal limit plate 123. The guide block 122 can be used to limit the movement of the intermediate tank 4 in the direction perpendicular to the rotation axis of the tipping frame 1, and the horizontal limit plate 123 can be used to limit the movement of the intermediate tank 4 in the direction of the rotation axis of the tipping frame 1; after completion, the locking structure 13 is extended inward and pressed on the top surface of the tank body 41, which can limit the movement of the intermediate tank 4 in the vertical direction perpendicular to the horizontal plane, thereby realizing the positioning of the intermediate tank 4 in the three-dimensional direction of the space, and the intermediate tank 4 can be firmly locked. Then, the entire tipping frame 1 is driven to rotate by the driving device, so that the tipping of the intermediate tank 4 can be realized. When the intermediate tank 4 of the second specification needs to be overturned, the intermediate tank 4 can be locked by simply turning the other positioning structure 12 upward.

[0041] Therefore, the intermediate tank tilting device in this embodiment is a double-station tilting device, which can realize the independent tilting of two intermediate tanks 4 of different specifications through one tilting device. When switching intermediate tanks 4 of different specifications, there is no need to install or disassemble other transition equipment, which completely solves the problem of space occupation and does not increase the workload of on-site staff. At the same time, through the cooperation of the guide block 122, the horizontal limit plate 123 and the locking structure 13, the intermediate tank 4 can be well guided and locked, which is more conducive to the rapid and stable disassembly and assembly of the intermediate tank 4.

[0042] In the specific implementation, refer to Figure 2 , guide slopes 1221 are formed on both sides of the top of the guide block 122. The guide block 122 is arranged at the top center of the positioning seat 121, and guide slopes 1221 are arranged on the top of the guide block 122 on both sides of the rotation axis of the tilting frame 1, which can play a guiding role when the two ear shafts 42 at the end of the tank body 41 slide down along both sides of the guide block 122.

[0043] The top of the horizontal limit plate 123 has a guide arc surface. The bottom of the horizontal limit plate 123 is a flat plate, and its plate surface is perpendicular to the top surface of the positioning seat 121. The top of the horizontal limit plate 123 gradually bends and tilts upward from the top of the flat plate to the outside of the positioning seat 121 to form an arc plate. The inner surface of the arc plate constitutes a guide arc surface, which can play a guiding role when the two ear shafts 42 at the end of the tank body 41 slide down along the two sides of the guide block 122.

[0044] To facilitate processing and installation, two mounting plates 124 are provided on both sides of the top surface of the positioning seat 121 close to the guide block 122, the bottom of the horizontal limiting plate 123 is vertically fixed on the mounting plate 124, and a reinforcing plate 125 is provided on the outer side surface of the horizontal limiting plate 123, and the reinforcing plate 125 is fixedly connected to the mounting plate 124.

[0045] Generally, the positioning seat 121 is a rectangular block, and its length direction is perpendicular to the rotation axis of the tipping frame 1. The guide block 122 is located in the middle of the positioning seat 121 and is fixedly connected to the positioning seat 121. The lower part of the guide block 122 is a rectangular block, and the upper two sides are the above-mentioned guide slopes 1221; the entire positioning seat 121, the guide block 122 and the crossbeam 111 are all welded from steel plates, and the positioning seat 121 and the guide block 122 form a box-type structure with an inverted T-shaped structure, and the top of the box-type structure is provided with a guiding and horizontal limiting structure (i.e., the guide block 122 and the horizontal limiting plate 123). The mounting plate 124 is a rectangular plate, the flat plate at the bottom of the horizontal limiting plate 123 is a rectangular plate, and the top is the above-mentioned arc-shaped plate. The horizontal limiting plate 123 is fixed to the outer edge of the mounting plate 124 away from the other positioning seat 121 along its length direction. The reinforcing plate 125 is located on the outer side of the horizontal limiting plate 123 and is fixed to the outer edge of the mounting plate 124 to locally strengthen the horizontal limiting plate 123 and ensure the stability of the structure.

[0046] Reference Figure 6 The locking structure 13 includes a driving member 131 and a slider 132. A mounting hole is opened at the top of the guide block 122. The slider 132 can be slidably inserted into the mounting hole. The driving member 131 is connected to the slider 132 and can drive the slider 132 to move. The slider 132 can extend out of the mounting hole and press on the top surface of the tank body 41.

[0047] The axial direction of the mounting hole is parallel to the rotational axis of the tilting frame 1. The driving member 131 can be, for example, a hydraulic cylinder, and the slider 132 can be, for example, a cylindrical locking pin. The cylindrical locking pin is threadedly connected to the telescopic rod of the hydraulic cylinder, and the cylinder body of the hydraulic cylinder can be bolted to the end surface of the guide block 122. In the initial state, the slider 132 is retracted into the mounting hole. When the ear shaft 42 of the intermediate tank 4 slides down and is stuck on both sides of the guide block 122, the driving member 131 drives the slider 132 to extend inward and press on the top surface of the placed tank body 41, thereby playing a locking role.

[0048] In a preferred embodiment, referring to Figure 1 , Figure 4 and Figure 8 The connecting frame 11 includes two cross beams 111 arranged in parallel and spaced apart. The length direction of the cross beams 111 is parallel to the rotation axis direction of the tilting frame 1. The bottom of the intermediate tank 4 can be accommodated in the interval area between the two cross beams 111. In this way, after the intermediate tank 4 is installed, the center of gravity of the intermediate tank 4 can be closer to the rotation center of the tilting frame 1, the torque is smaller, the force is more reasonable, and the structure is more stable.

[0049] Generally, the height of the cross beam 111 is relatively small, and after one intermediate tank 4 is installed, another intermediate tank 4 cannot be installed at the same time. In an optional embodiment, by designing the height of the cross beam 111 and the size of the positioning seat 121, two intermediate tanks 4 can be installed on the tilting frame 1 at the same time, and two intermediate tanks 4 of different specifications can be tilted at the same time as needed.

[0050] Further, see Figure 1 The driving device includes two groups of driving structures 2 symmetrically arranged at both ends of the connecting frame 11, wherein two positioning seats 121 in one group of positioning structures 12 are located at both ends of the connecting frame 11, and the driving end of each group of driving structures 2 is connected to the positioning seat 121 located at the end of the connecting frame 11. That is, the distance between the two positioning seats 121 of one group of positioning structures 12 is greater than the distance between the two positioning seats 121 of the other group of positioning structures 12, and the driving end is connected to the positioning seat 121 with a larger distance.

[0051] Specifically, the driving structure 2 includes a motor 21, a first coupling 22, a reducer 24, a second coupling 25 and a driving shaft 26 connected in sequence. The driving shaft 26 is connected to the corresponding positioning seat 121 (that is, the end of the driving shaft 26 constitutes the driving end). A brake 23 is also provided between the motor 21 and the reducer 24, and the brake 23 is clamped on the first coupling 22.

[0052] The first coupling 22 can be, for example, an elastic pin coupling, the brake 23 can be an electric hydraulic block brake, the output shaft of the motor 21 is connected to the input shaft of the reducer 24 through an elastic pin coupling with a brake wheel, the brake 23 is arranged between the motor 21 and the reducer 24 and is held on the elastic pin coupling; the second coupling 25 can be a drum gear coupling, and the reducer 24 can be a star gear reducer 24.

[0053] The intermediate tank tilting device further comprises two bases 3 , on which the motor 21 , the reducer 24 and the brake 23 are all fixed, and the driving shaft 26 is supported on the bases 3 via bearings and bearing seats 31 .

[0054] Generally, two bearing seats 31 are fixed on the base 3, and the drive shaft 26 is connected to the two bearing seats 31 through two bearings. The two bases 3 can be welded from steel plates and arranged on both sides of the tilting frame 1. When installed, the bases 3 are fixed to the ground through anchor bolts to provide support for the entire device.

[0055] Further, the two specifications of the intermediate tank 4 are respectively recorded as the first intermediate tank and the second intermediate tank, and the two sets of positioning structures 12 are respectively recorded as the first positioning structure and the second positioning structure. The interval between the two positioning seats 121 in the first positioning structure matches the size of the first intermediate tank, and the interval between the two positioning seats 121 in the second positioning structure matches the size of the second intermediate tank. The two positioning seats 121 of the first positioning structure are located at both ends of the cross beam 111, and the two positioning seats 121 of the second positioning structure are located in the middle of the cross beam 111. The process of using the device to tip over the intermediate tanks 4 of the two specifications is as follows:

[0056] Reference Figure 3 and Figure 4 When the first intermediate tank needs to be tilted, the motor 21 is started to drive the tilting frame 1 to rotate until the first positioning structure of the tilting frame 1 is upward. At this time, the brake 23 brakes to keep the tilting frame 1 from rotating. The positioning seat 121 and the guide block 122 of the tilting frame 1 are in an inverted T-shaped structure as a whole, and there are two ear shafts 42 on both sides of the first intermediate tank. When the first intermediate tank is installed, the two shafts on both sides of the tank body 41 are respectively clamped to the inverted T-shaped structure of the tilting frame 1 (that is, clamped on both sides of the guide block 122), and at the same time, a horizontal limit plate 123 is provided on the side of the inverted T-shaped structure. Through this structure, the first intermediate tank is positioned in all horizontal directions. After the first intermediate tank is placed, the hydraulic cylinders on both sides are started to extend the cylindrical locking pin from the mounting hole of the guide block 122 and press it on the first intermediate tank. Through the above-mentioned locking structure 13, the first intermediate tank is positioned in all vertical directions. After the locking is completed, the brake 23 is released, and the motor 21 drives the tilting frame 1 to complete the tilting action. After the tipping is completed, the first tundish is rotated upward, the locking structure 13 is released, and the first tundish is lifted out.

[0057] Reference Figure 7 and Figure 8 When the second intermediate tank needs to be tilted, start the motor 21 to drive the tilting frame 1 to rotate until the second positioning structure of the tilting frame 1 is facing upward. At this time, the brake 23 brakes to keep the tilting frame 1 from rotating. The locking process of installing the second intermediate tank is similar to the locking process of installing the first intermediate tank, which will not be repeated here. After the locking of the second intermediate tank is completed, release the brake 23, and the motor 21 drives the tilting frame 1 to complete the tilting action. After the tilting is completed, rotate the second intermediate tank to the top, release the locking structure 13, and lift out the second intermediate tank.

[0058] The above is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
