Description

Technical Field

[0001] This utility model belongs to the technical field of float glass production equipment. Specifically, this utility model relates to a float glass flow channel cover brick lifting device. Background Technology

[0002] In the float glass production process, the runner area requires cover bricks to cover and protect the internal structure. However, in actual production, especially after high-temperature conditions such as baking, the cover bricks are prone to fracture in the central area. Traditional cover brick lifting tools are mostly structurally fixed and lack the ability to adapt to deformation caused by thermal expansion and contraction of the cover bricks and lifting equipment. Under high-temperature environments, the asynchronous deformation of the cover bricks and lifting equipment leads to uneven stress on the lifting points of the cover bricks, resulting in excessive stress on the central area of ​​the cover bricks and ultimately causing fracture.

[0003] Chinese patent (publication number: 109592883A) discloses a suspension structure for preventing the breakage of 3D high-alumina glass flow channel cover bricks. The structure includes a main beam with lifting lugs at both ends. It also includes multiple clamping plates for connecting the cover bricks, which are sequentially arranged below the main beam with gaps between adjacent plates. The sides of the clamping plates are connected to the main beam via connectors. However, this suspension structure for preventing the breakage of 3D high-alumina glass flow channel cover bricks is prone to breakage in the middle area of ​​the cover bricks. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems. Its purpose is to provide a float glass flow channel cover brick lifting device that can stably clamp the cover brick and reduce the breakage of the cover brick. To achieve the above purpose, the technical solution adopted by this utility model is as follows: a float glass flow channel cover brick lifting device, including a steel beam, a cover brick and a flow channel, wherein a clamping device is provided on the steel beam and a support structure is provided at both ends of the steel beam.

[0005] The clamping device includes a lifting clamp, a hanging component is provided on the steel beam, the hanging component is connected to the lifting clamp, a clamping plate is provided at both ends of the lifting clamp, the lifting clamp is sleeved on the cover brick, and the clamping plate abuts against the cover brick.

[0006] The suspension component includes a suspension rod and a first pin. One end of the suspension rod passes through a steel beam and is connected to the steel beam. The other end of the suspension rod is connected to a bushing. The bushing is fitted onto a clamping clamp. The first pin connects the bushing and the clamping clamp.

[0007] A second pin is provided between the clamping plate and the lifting clamp, and the clamping plate and the lifting clamp are connected by the second pin.

[0008] The support structure includes a support rod, one end of which is mounted on a steel beam and fixed with a nut, and the other end of which abuts against the cover brick.

[0009] The steel beam has a hollow structure.

[0010] The lifting clamp has a U-shaped structure.

[0011] A pad is provided on the support rod, and the pad abuts against the cover brick.

[0012] The technical advantages of this invention are as follows: The U-shaped clamping structure for holding the cover brick reduces impact and shaking. The adjustable length of the extended steel beam allows for changing the height of the clamping clamp, ensuring initial force balance at each clamping point during cold assembly. Furthermore, after the flow channel heats up, secondary adjustments are made based on the deformation of the cover brick, clamping clamp, and clamping plate, ensuring uniform force distribution on the cover brick. The clamping plate and clamping clamp, hinged via a second pin, automatically conform to the surface shape of the cover brick, ensuring even clamping force distribution on the cover brick surface regardless of whether it is cold or hot. Simultaneously, by adjusting the height of the support rod, with its other end abutting against the cover brick, the weight of the central area of ​​the cover brick is distributed across both ends of the cover brick through the lifting device and its support points, preventing excessive stress on the central area of ​​the cover brick at high temperatures, which could lead to breakage.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] like Figures 1-3 As shown, a float glass flow channel cover brick lifting device includes a steel beam 1, a cover brick 2, and a flow channel 3. A clamping device 4 is installed on the steel beam 1, and support structures 5 are installed at both ends of the steel beam 1. The steel beam 1 bears the weight of the clamping device 4, the support structures 5, and the cover brick 2. The cover brick 2 spans across and covers the edge of the flow channel 3, preventing external impurities from entering the flow channel and maintaining a stable internal temperature to ensure the quality of the molten glass production. The flow channel 3 is the channel for conveying molten glass during float glass production. The clamping device 4, located on the steel beam 1, clamps and fixes the cover brick 2. The support structures 5 are located at the ends of the steel beam 1, concentrating the weight of the clamping device 4 and the cover brick 2 to the end area of ​​the cover brick 2, preventing the middle of the cover brick 2 from breaking due to overload.

[0020] The clamping device 4 includes a lifting clamp 401. A hanging component 41 is provided on the steel beam 1. The hanging component 41 is connected to the lifting clamp 401. Clamping plates 402 are provided at both ends of the lifting clamp 401. The lifting clamp 401 is sleeved on the cover brick 2, and the clamping plates 402 abut against the cover brick 2. Multiple clamping devices 4 are provided, evenly spaced on the steel beam 1. The lifting clamp 401 is installed on the hanging component 41, and the two ends of the hanging component 41 are connected to the clamping plate 402. The lifting clamp 401 is sleeved on the cover brick 2, and the clamping plate 402 tightly clamps the cover brick 2. The hanging component 41 connects the lifting clamp 401 to the steel beam 1. The height of the lifting clamp 401 can be adjusted by the hanging component 41. After heating and baking, the height of the hanging component 41 is adjusted according to the actual deformation of the cover brick 2, the lifting clamp 401 and the clamping plate 402, so that the lifting points of each clamping device 4 are evenly stressed, reducing the risk of breakage of the cover brick 2.

[0021] The hanging component 41 includes a hanging rod 411 and a first pin 412. One end of the hanging rod 411 passes through the steel beam 1 and is connected to the steel beam 1. The other end of the hanging rod 411 is connected to a bushing 413. The bushing 413 is sleeved on the clamping clamp 401. The first pin 412 connects the bushing 413 and the clamping clamp 401. One end of the lifting rod 411 passes through the steel beam 1 and is connected by a nut. Its length extending beyond the steel beam can be adjusted by rotation, thus changing the height of the clamping clamp 401. This allows for initial force balance at each clamping point 4 during assembly and, after the flow channel heats up, secondary adjustments can be made based on the deformation of the cover brick 2, clamping clamp 401, and clamping plate 402, ensuring uniform force on the cover brick 2. The lifting rod 411 is fixedly connected to the bushing 413, transferring the load-bearing capacity of the steel beam 1 to the bushing 413. The bushing 413 is fitted onto the clamping clamp 401, and a first pin 412 passes through the bushing 413 and clamping clamp 401, connecting them together. Through the first pin 412, when the height is adjusted by the lifting rod 411 or when the cover brick deforms, the clamping clamp 401 can adaptively adjust its posture by rotating around the first pin 412.

[0022] A second pin 6 is provided between the clamping plate 402 and the lifting clamp 401, and the clamping plate 402 and the lifting clamp 401 are connected by the second pin 6. The second pin 6 passes through the clamping plate 402 and forms a rotatable hinge with the lifting clamp 401. The clamping plate 402 can rotate freely around the pin and can automatically adjust its angle according to the surface shape of the cover brick 2: during cold assembly, as the height of the hanging component 41 is adjusted, the clamping plate 402 fits against the surface of the cover brick 2; when the cover brick 2 is deformed due to high-temperature baking, the clamping plate 402 can rotate synchronously with the deformation of the cover brick 2, always maintaining a tight fit. This ensures that the clamping force of the clamping plate 402 is evenly distributed on the surface of the cover brick 2, regardless of whether the working conditions are cold or hot.

[0023] The support structure 5 includes a support rod 501. One end of the support rod 501 is mounted on the steel beam 1 and fixed with a nut. The support rod 501 is located at both ends of the steel beam 1, and the other end of the support rod 501 abuts against the cover brick 2. One end of the support rod 501 passes through the steel beam 1 and is fixed with a nut. This nut fixation allows for adjustment of the height of the support rod 501. The other end of the support rod 501 abuts against the cover brick 2, ensuring that the support points of the cover brick 2 fall at both ends of the cover brick 2, preventing the middle area of ​​the cover brick 2 from breaking at high temperatures.

[0024] Steel beam 1 has a hollow structure. While ensuring load-bearing strength, the hollow structure can significantly reduce its own weight, while increasing the heat dissipation area, reducing uneven thermal deformation under high temperature, and maintaining the stress balance of the lifting device.

[0025] The lifting clamp 401 has a U-shaped structure. The opening end of the lifting clamp 401 is relatively small, while the inner opening end of the lifting clamp 401 is relatively large. The lifting clamp 401 adopts a U-shaped structure that is narrow on the outside and wide on the inside. This structure can be used to fit the cover brick 2, which can enhance the relative stability of the lifting clamp 401 in clamping the cover brick 2 and reduce the shaking of the lifting clamp 401 during the lifting process.

[0026] A pad 502 is provided on the support rod 501, and the pad 502 abuts against the cover brick 2. By placing the pad 502 at the end of the support rod 501, the pad 502 can evenly distribute the concentrated support force transmitted by the support rod 501 to a larger area at the end of the cover brick 2, which greatly reduces the pressure per unit area. At the same time, by abutting against the cover brick 2, the pad 502 can prevent the support rod 501 from causing wear to the cover brick 2.

[0027] The role and effect of the embodiments

[0028] The U-shaped clamping clamp 401 is used to hold the cover brick, reducing bumps and shaking. The length of the lifting rod 411 extending out of the steel beam can be adjusted by rotating the lifting rod 411, which changes the height of the clamping clamp 401. This ensures that the initial force of each clamping device 4 is balanced during cold assembly. After the flow channel heats up, a secondary adjustment can be made based on the deformation of the cover brick 2, the clamping clamp 401, and the clamping plate 402, ensuring that the force on the cover brick 2 is always uniform. The clamping plate 402 and the clamping clamp 401 are hinged through the second pin 6, which can automatically fit the surface shape of the cover brick 2, ensuring that the clamping force of the clamping plate 402 is evenly distributed on the surface of the cover brick 2 under both cold and hot conditions. At the same time, by adjusting the height of the support rod 501, the other end of the support rod 501 abuts against the cover brick 2, so that the weight of the middle area of ​​the cover brick 2 is distributed to both ends of the cover brick 2 through the lifting device and its support point, avoiding excessive force on the middle area of ​​the cover brick 2 at high temperature, which could lead to breakage of the cover brick 2.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
