Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, specifically to a refractory brick clamping device. Background Technology
[0002] The crack resistance of refractory bricks directly affects their service life and safety performance. In high-temperature environments, if refractory bricks crack or break, it may lead to instability in the furnace structure or even safety accidents. Therefore, it is necessary to evaluate the performance of refractory bricks under high-temperature conditions. This requires placing samples in a high-temperature furnace for heat treatment to simulate the actual operating environment. The refractory bricks are then removed from the high-temperature furnace during or after the heat treatment process.
[0003] Refractory bricks used for heat treatment are characterized by their large size and heavy weight. However, existing refractory brick clamping and sampling tools mostly use ordinary clamps with traditional structures, using two clamps to hold the refractory bricks. During the movement of the refractory bricks, they are easy to fall, which not only poses safety hazards such as crushing injuries, high-temperature burns, and abrasions to on-site personnel, but also has low sample loading and unloading efficiency, affecting work efficiency. Summary of the Invention
[0004] This invention addresses the problems of unstable clamping and low sample loading / unloading efficiency in existing refractory brick clamping devices by providing a refractory brick clamping device that is easy to operate, provides stable clamping of refractory bricks, and saves more time and effort.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A refractory brick clamping device includes a first clamping rod and a second clamping rod. The first clamping rod has a gripping portion at a first end and a first clamping portion at a second end. The first clamping rod is slidably connected to the second clamping rod via a connecting portion. The gripping portion is used to drive the first clamping rod to move relative to the second clamping rod. The second clamping rod has a second clamping portion at its second end away from the gripping portion. The second clamping portion and the first clamping portion are arranged parallel to each other, forming a clamping space for clamping the refractory brick. By gripping the gripping portion, the first clamping rod can be pushed to move away from or towards the second clamping portion.
[0007] Furthermore, the first end of the first clamping rod is bent inward to form a gripping portion. The gripping portion is integrated with the first clamping rod, resulting in higher strength during use.
[0008] Furthermore, the first clamping rod and the first clamping part are arranged on the same straight line, and their cross-sections are the same. The first clamping rod can be disengaged from the connecting part, facilitating the storage of the clamping device.
[0009] Furthermore, a connecting portion is fixedly provided on the second clamping rod. One end of the connecting portion is fixedly connected to the second clamping rod, and the other end is provided with a through hole, in which the first clamping rod is movably disposed. The second clamping rod can slide relative to the first clamping rod.
[0010] Furthermore, two connecting parts are arranged in parallel on the second clamping rod, one of which is located at the first end of the second clamping rod. The connecting part at the first end is correspondingly arranged with the gripping part, so that in use, the connecting part and the gripping part can be held simultaneously with one hand, realizing one-handed operation and clamping of refractory bricks.
[0011] Furthermore, the second clamping part is U-shaped, and its height is greater than that of the connecting part. The horizontal section of the second clamping part is fixed to the second clamping rod. This allows the first clamping rod on the connecting part to abut against the surface of the refractory brick.
[0012] Furthermore, the thickness at the connection between the second clamping part and the second clamping rod is greater than the thickness at the end of the second clamping part, and both the upper and lower surfaces of the second clamping part have a smooth transition. This facilitates the insertion of the second clamping part into the gap between the refractory bricks.
[0013] Furthermore, the length of the second clamping rod is greater than 70cm. This keeps personnel away from the high-temperature furnace during operation, preventing burns.
[0014] The beneficial effects of this utility model through the above technical solution are as follows:
[0015] This utility model is equipped with a first clamping rod and a second clamping rod that slide relative to each other. The first clamping part can be moved away from or closer to the second clamping part by the holding part, which has a wide adjustment range and can clamp refractory bricks of various thicknesses.
[0016] The clamping direction and lifting direction of this invention are set on the same straight line, which makes the refractory brick more stable under force, less prone to slippage during the transfer of the refractory brick, and easy to operate without damaging the surface of the refractory brick.
[0017] The gripping part of this utility model is far away from the clamping space of the refractory brick, which can be used for the layout and sampling of existing refractory brick heat treatment, avoiding safety hazards such as high temperature burns and abrasions, and has high sample loading and unloading efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0023] like Figures 1-3 As shown, this embodiment provides a refractory brick clamping device, specifically relating to sampling and placement during refractory brick heat treatment. The refractory brick clamping device includes a first clamping rod 1 and a second clamping rod 2, which are movably configured. The first clamping rod 1 can move relative to the second clamping rod 2, and the refractory brick is clamped between the first clamping rod 1 and the second clamping rod 2.
[0024] like Figure 1 As shown, the first clamping rod 1 has a gripping part 11 at its first end and a first clamping part 12 at its second end. The first clamping rod 1 is slidably connected to the second clamping rod 2 through a connecting part 21. The gripping part 11 is used to drive the first clamping rod 1 to move relative to the second clamping rod 2. The second clamping part 22 is provided at the second end of the second clamping rod 2 away from the gripping part 11. The second clamping part 22 is arranged parallel to the first clamping part 12, and a clamping space for clamping refractory bricks is formed between them.
[0025] Specifically, the first clamping rod 1 and the second clamping rod 2 are made of round steel tubes. The first end of the first clamping rod 1 is bent inward to form a gripping part 11. By holding the gripping part 11, the first clamping rod 1 can be pushed to move away from or closer to the second clamping part 22.
[0026] In one possible implementation, the first clamping rod 1 and the first clamping part 12 are arranged on the same straight line, and their cross-sections are the same. That is, a part of the first clamping rod 1 serves as the first clamping part 12. During the transfer of refractory bricks, the first clamping part 12 abuts against the refractory bricks and prevents them from moving. In this case, when the clamping device is not used, the first clamping rod 1 can be completely pulled out from the connecting part 21, saving floor space, facilitating storage, and simplifying assembly and disassembly, reducing learning costs and making it easy to promote.
[0027] A connecting part 21 is fixedly provided on the second clamping rod 2. One end of the connecting part 21 is fixedly connected to the second clamping rod 2, and the other end is provided with a through hole. The first clamping rod 1 is movably disposed in the through hole. Specifically, the connecting part 21 has a connecting rod vertically connected to the second clamping rod 2 and a hollow round tube formed at the other end of the connecting rod. The hollow round tube is inserted into the first clamping rod 1.
[0028] In one possible implementation, two connecting portions 21 are arranged in parallel on the second clamping rod 2. One connecting portion 21 is located at the first end of the second clamping rod 2, and the other connecting portion 21 is located in the middle of the second clamping rod 2. The first clamping rod 1 is inserted into both connecting portions 21, which makes the positioning of the first clamping rod 1 more accurate and prevents the first clamping rod 1 from shaking during the clamping of the refractory brick.
[0029] When using, such as Figure 2 As shown, the connecting part 21 and the holding part 11 at the ends can be held simultaneously with one hand. Through the gripping action of the hand, the first clamping part 12 and the second clamping part 22 are clamped together, thus removing the refractory brick from the furnace. Figure 3 As shown, when transferring refractory bricks, since the clamping direction and the gripping direction of the hand are in the same vertical direction, the bottom of the refractory bricks is supported by the second clamping part 22 during the transfer process, making it less likely for the refractory bricks to slip off, and making manual operation more labor-saving.
[0030] To increase the contact area between the second clamping part 22 and the refractory brick, the second clamping part 22 is U-shaped, and its height is greater than that of the connecting part 21, allowing the first clamping rod 1 on the connecting part 21 to abut against the surface of the refractory brick. The horizontal section of the second clamping part 22 is fixed to the second clamping rod 2. In this embodiment, the direction of the second clamping part 22 is perpendicular to the direction of the second clamping rod 2. In use, using the horizontal section of the second clamping part 22 as a fulcrum, heavier refractory bricks can be easily lifted, saving manpower.
[0031] To facilitate the insertion of the second clamping part 22 into the gaps between the refractory bricks, the thickness at the connection between the second clamping part 22 and the second clamping rod 2 is greater than the thickness at the end of the second clamping part 22, and both the upper and lower surfaces of the second clamping part 22 are smoothly transitioned, allowing for easy lifting of the refractory bricks and saving operation time. In this embodiment, the second clamping part 22 is made of ordinary steel.
[0032] To facilitate sampling and placement of refractory bricks during heat treatment, the second clamping rod 2 is longer than 70cm, exceeding the dimensions of 95% of high-temperature furnace chambers. This allows operators to stay away from the high-temperature furnace chamber, avoiding safety issues such as burns, scalds, and scratches. Furthermore, when using the clamping device described in this invention to hold refractory bricks, workers can operate upright, avoiding frequent bending over to pick up and place bricks, thus improving worker comfort and significantly reducing labor intensity.
[0033] The working principle of this utility model:
[0034] In use, the clamping device is inserted into the high-temperature furnace, and the second clamping part 22 is placed close to the side of the refractory brick away from the furnace door. Force is applied to bring the holding part 11 close to the connecting part 21, so that the first clamping part 12 moves closer to the second clamping part 22 and is pressed against the other side of the refractory brick near the furnace door. After the refractory brick is clamped, force is applied again to remove the clamping device from the high-temperature furnace. During this process, the worker's hands are kept away from the high-temperature furnace throughout, avoiding safety issues such as burns, scalds, and cuts caused by high temperatures.
[0035] When transferring refractory bricks, such as Figure 3 As shown, since the clamping direction of the refractory brick is in the vertical direction, the upper surface of the second clamping part 22 supports the refractory brick during the transfer process, and the refractory brick will not easily slip off, thus avoiding damage to the refractory brick and injury to personnel, and making manual operation more labor-saving.
[0036] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
