Description

Technical Field

[0001] This utility model relates to the field of continuous casting equipment technology, and in particular to a tilting device for a continuous casting intermediate tank. Background Technology

[0002] In continuous casting production, the tundish is used to store and distribute molten steel. After completing a casting task, the tundish needs to be tilted to clean up residual molten steel and perform maintenance. Existing tundish tilting devices suffer from poor stability and low control precision during the tilting process, leading to a high equipment failure rate, affecting production efficiency, and potentially causing safety accidents such as the tundish falling due to clamping device failure during tilting. Therefore, there is an urgent need for a continuous casting tundish tilting device with a reasonable structure, stable operation, and high control precision. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a tilting device for a continuous casting tundish, which solves the problems of poor stability, low control precision, and low safety in existing tilting devices, thereby achieving safe, stable, and precise tilting operation of the tundish and improving production efficiency and equipment reliability.

[0004] This utility model is achieved by the following specific technical means: a continuous casting tundish tilting device, characterized in that it includes: a power unit, a tilting platform, a clamping device, a support device, a pressure sensor, a cold steel treatment device, a stroke control device, an tundish, and a workbench;

[0005] The power unit is used to provide power for tilting the intermediate tank. It includes a power unit base, a motor, a coupling, a bearing housing, a self-aligning roller bearing with a locking sleeve, bolts, a shaft, and a key. The power unit base is fixed to the workbench by bolts. The motor is mounted on the power unit base and connected to the shaft by a coupling. The shaft is also provided with a key for transmitting torque. The shaft is mounted in the bearing housing by a self-aligning roller bearing with a locking sleeve.

[0006] The tilting platform is connected to the shaft of the power unit, and tilts around the shaft under the drive of the power unit, with the intermediate tank placed on the tilting platform.

[0007] The clamping device includes a clamping arm, an electro-hydraulic cylinder, and a support. The support is fixed on the tilting platform, and the electro-hydraulic cylinder is mounted on the support via a shaft. Its piston rod is connected to the clamping arm. Through the extension and retraction of the electro-hydraulic cylinder, the clamping arm is driven to clamp or release the intermediate tank, ensuring the stability of the intermediate tank during the tilting process.

[0008] The support device consists of a support hydraulic cylinder and a support pressure head. The cylinder body of the support hydraulic cylinder is fixed on the workbench, and the support pressure head is connected to the piston rod of the support hydraulic cylinder. When the intermediate tank tilting device is in the standby position, the support device can provide auxiliary support for the tilting platform to improve the stability of the device. After the intermediate tank tilting device has fully tilted in operation, the support device can provide auxiliary clamping for the clamping arm to prevent the intermediate tank from falling due to clamping device failure or other reasons, thereby improving the safety and stability of the device.

[0009] The pressure sensor is installed on the tilting platform to monitor the force on the tilting platform and send the feedback signal to the control system so as to control the operation of other devices.

[0010] The cold steel processing device includes a lifting hydraulic cylinder, a top block, a protective plate, and an electric lifting platform. The lifting hydraulic cylinder is installed on the electric lifting platform, and the top block is connected to the piston rod of the lifting hydraulic cylinder. The protective plate is located in the middle of the top block and the lifting hydraulic cylinder. When the intermediate tank is overturned, the height of the lifting hydraulic cylinder can be adjusted by the electric lifting platform to prevent collision with the intermediate tank. When there is cold steel in the intermediate tank, the lifting hydraulic cylinder drives the top block to process the cold steel.

[0011] The stroke control device includes a proximity switch, a proximity switch sensing device, and a bracket. The bracket is welded and fixed to the workbench. The proximity switch is mounted on the bracket by bolts. The proximity switch sensing device is set on the shaft connected to the tilting platform. Through the cooperation of the proximity switch and the proximity switch sensing device, the tilting angle and stroke of the tilting platform are precisely controlled.

[0012] Furthermore: There are 4 sets of clamping devices, all located at the four corners of the tilting platform. They are all in the open state when in the standby position and in the clamped state when in the working position.

[0013] Furthermore: There are 4 sets of support devices, all located at the four corners directly below the tilting platform, and corresponding vertically to the clamping devices.

[0014] Furthermore, both sides of the tilting platform are equipped with the same power unit, thus ensuring that both sides of the tilting platform can be tilted synchronously.

[0015] The beneficial effects of this utility model are:

[0016] This invention achieves a stable tilting structure through the coordinated operation of its power unit, tilting platform, clamping device, and support device. The support device provides support when the intermediate tank is placed on the tilting platform, enhancing the overall stability of the device and reducing the risk of swaying and tilting during the process. After the intermediate tank tilting device is fully tilted in its working position, the support device can assist in clamping the clamping arm, effectively preventing dangerous situations such as falling after tilting. Pressure sensors monitor the force on the tilting platform in real time, providing feedback to the control system for timely adjustments to the support device. The stroke control device precisely controls the tilting angle and stroke through proximity switches and proximity switch sensors, achieving precise control of the intermediate tank tilting process. The clamping device firmly clamps the intermediate tank, adapting to the tilting requirements of intermediate tanks of different specifications, thus enhancing the device's versatility. The installed cold steel handling device can effectively process cold steel in the intermediate tank, eliminating the need for complex manual cleaning and improving production efficiency. The protective plate effectively prevents damage to the lifting hydraulic cylinder from falling cold steel during the operation of the cold steel handling device, thus protecting the equipment and reducing the probability of equipment failure. The electric lifting platform adjusts the height of the lifting hydraulic cylinder to prevent collisions with the intermediate tank during tipping. Attached Figure Description

[0024] like Figure 1-5 As shown, this utility model discloses a tilting device for a continuous casting tundish, characterized in that it includes: a power unit 1, a tilting platform 2, a clamping device 3, a support device 4, a pressure sensor 5, a cold steel treatment device 6, a stroke control device 7, a tundish 9, and a worktable 10.

[0025] The power unit 1 is used to provide power for tilting the intermediate tank. It includes a power unit base 101, a motor 102, a coupling 103, a bearing seat 104, a self-aligning roller bearing 105 with a locking sleeve, a bolt 106, a shaft 107, and a key 108. The power unit base 101 is fixed to the workbench 10 by bolts 106. The motor 102 is mounted on the power unit base 101. The motor 102 is connected to the shaft 107 by the coupling 103. The shaft 107 is also provided with a key 108 for transmitting torque. The shaft 107 is mounted in the bearing seat 104 by the self-aligning roller bearing 105 with a locking sleeve.

[0026] The tilting platform 2 is fixedly connected to the shaft 107 of the power unit 1. Driven by the power unit 1, it tilts along the shaft 107, with the intermediate tank 9 placed on the tilting platform 2. The intermediate tank has an approximately trapezoidal cross-section, wider at the top and narrower at the bottom, and is fitted into the frame of the tilting platform. The upper part or the upper flange of the intermediate tank mates with the frame and is clamped by a clamping device. The intermediate tank also has ears on both sides, which mate with the frame.

[0027] The clamping device 3 includes a clamping arm 301, an electro-hydraulic cylinder 302, and a support 303. The support 303 is fixed on the tilting platform 2. The electro-hydraulic cylinder 302 is mounted on the support 303 via a hinge shaft. Its piston rod is hinged to the clamping arm 301. A clamping hinge shaft is provided at the lower part of the clamping arm. The clamping hinge shaft is fixed on the tilting platform via a bracket. Through the extension and retraction of the electro-hydraulic cylinder 302, the clamping arm 301 is driven to clamp or release the intermediate tank 9, ensuring the stability of the intermediate tank during the tilting process.

[0028] The support device 4 consists of a support hydraulic cylinder 401 and a support pressure head 402. The cylinder body of the support hydraulic cylinder 401 is fixed on the workbench 10, and the support pressure head 402 is connected to the piston rod of the support hydraulic cylinder 401. When the intermediate tank tilting device is in the standby position, the support device 4 can provide auxiliary support for the tilting platform 2 to improve the stability of the device. After the intermediate tank tilting device has fully tilted in operation, the support device 4 can provide auxiliary support and clamping for the clamping arm 301 to prevent the intermediate tank from falling due to the failure of the clamping device 3, thereby improving the safety and stability of the device.

[0029] The pressure sensor 5 is installed on the tilting platform 2 and cooperates with the intermediate tank to monitor the force on the tilting platform 2, thereby determining the cooperation between the intermediate tank and the tilting platform.

[0030] The cold steel processing device 6 includes a lifting hydraulic cylinder 601, a top block 602, a protective plate 603, and an electric lifting platform 604. The lifting hydraulic cylinder 601 is mounted on the electric lifting platform 604. The top block 602 is connected to the piston rod of the lifting hydraulic cylinder 601. The protective plate 603 is located between the top block 602 and the lifting hydraulic cylinder 601 and is connected to the lifting platform via a bracket. When the intermediate tank 9 tilts, the height of the lifting hydraulic cylinder 601 can be adjusted via the electric lifting platform 604 to prevent collision with the intermediate tank 9. When there is cold steel in the intermediate tank 9, the lifting hydraulic cylinder 601 drives the top block 602 to process the cold steel. The electric lifting platform is an existing structure that can realize lifting functions.

[0031] The stroke control device 7 includes a proximity switch 701, a proximity switch sensing device 702, and a bracket 703. The bracket 703 is welded and fixed on the workbench 10. The proximity switch 701 is mounted on the bracket 703 by bolts. The proximity switch sensing device 702 is set on the shaft 107 connected to the tilting platform 2. The proximity switch 701 and the proximity switch sensing device 702 work together to determine the tilting status of the tilting platform 2.

[0032] Preferably, there are 4 sets of clamping devices 3, all of which are set at the four corners of the tilting platform 2. They are all in the open state when in the standby position and in the clamped state when in the working position.

[0033] Preferably, there are 4 sets of support devices 4, all of which are set at the four corners directly below the tilting platform 2 and are directly corresponding to the clamping device 3 vertically.

[0034] Preferably, the tilting platform 2 is equipped with the same power unit 1 on both sides, so as to ensure that the two sides of the tilting platform 2 can be tilted synchronously.

[0035] The working process of this utility model is as follows:

[0036] Before the intermediate tank is placed on the tilting device, the tilting frame is in standby position, the intermediate tank clamping mechanism is in the open state, and the support device 4 is in working state, contacting and supporting the tilting frame. The support hydraulic cylinder 401 controls the piston rod to drive the support pressure head 402 to make close contact with the bottom of the tilting platform 2 to provide support, enhance the stability of the tilting platform 2, and reduce the risk of shaking and tilting during the lifting of the intermediate tank 9. When the intermediate tank 9 is lifted onto the tilting platform 2, the pressure sensor 5 starts to work. When the pressure sensor 5 index is greater than a certain value, it feeds back a signal to the control system. After 10 seconds, the control system automatically controls the electro-hydraulic cylinder 302 to work. The piston rod of the electro-hydraulic cylinder 302 extends, driving the clamping arm 301 to move towards the intermediate tank 9 until the intermediate tank 9 is firmly clamped, ensuring that the intermediate tank will not be displaced during the subsequent tilting process. Subsequently, the system controls the support hydraulic cylinder 401 to descend, and the support pressure head 402 retracts to its lowest position. Then, the motor 102 of the power unit 1 is activated. The motor 102 drives the shaft 107 to rotate via the coupling 103, thereby causing the tilting platform 2 and the intermediate tank 9 to tilt as a whole. During the tilting process, the pressure sensor 5 monitors the force on the tilting platform 2 in real time and feeds the signal back to the control system. The control system adjusts the output power of the motor 102 based on the feedback signal to ensure a smooth tilting process. The proximity switch 701 of the stroke control device 7 monitors the position of the proximity switch sensing device 702 in real time. When the proximity switch 701 senses the proximity switch sensing device 702, the control system issues a command, and the motor 102 stops rotating, completing the tilting operation. At this time, the control system activates the support hydraulic cylinder 401 of the support device 4. The support hydraulic cylinder 401 extends by controlling the piston rod to bring the support pressure head 402 into close contact with the clamping arm 301, providing auxiliary clamping and reducing the risk of the intermediate tank 9 falling. If there is cold steel in the intermediate tank 9, the lifting hydraulic cylinder 601 of the cold steel handling device 6 can drive the top block 602 to push out or loosen the cold steel. After the handling is completed, the electric lifting platform 604 drives the lifting hydraulic cylinder 601 to descend and reset. After the cold steel and related materials are handled, the control system issues a command to control the support device 4 to reset, and then controls the motor 102 to reverse, so that the tilting platform 2 is reset. Then, the electro-hydraulic integrated cylinder 302 is controlled to reset the clamping arm 301, completing the tilting process.

[0037] The specific function of this embodiment is:

[0038] This utility model is mainly used for tilting residual molten steel in an intermediate tank 9. Through the coordinated operation of the power unit 1, tilting platform 2, clamping device 3, and support device 4, a stable tilting structure is formed. The support device 4 provides support when the intermediate tank 9 is placed on the tilting platform 2, enhancing the overall stability of the device and reducing the risk of shaking and tilting during the process. After the intermediate tank 9 is fully tilted in its working position, the support device 4 can assist in clamping the clamping arm 301, effectively preventing the tank 9 from falling after tilting. The pressure sensor 5 monitors the force on the tilting platform 2 in real time, providing feedback to the control system for timely adjustment of the support device 4. The stroke control device 7 precisely controls the tilting angle and stroke through the proximity switch 701 and proximity switch sensing device 702, achieving precise control of the tilting process of the intermediate tank 9. The clamping device 3 can firmly clamp the intermediate tank 9, adapting to the tilting requirements of intermediate tanks 9 of different specifications, thus enhancing the versatility of the device. Multiple cold steel handling devices 6 are installed, which can effectively pressurize the intermediate tank 9 when cold steel is present, improving production efficiency. The protective plate 603 can effectively prevent damage to the lifting hydraulic cylinder 601 from falling cold steel during the operation of the cold steel handling device 6, thereby protecting the equipment and reducing the probability of equipment failure. The electric lifting platform 604 adjusts the height of the lifting hydraulic cylinder 601 to prevent collision with the intermediate tank 9 when it is overturned.
