Description

Technical Field

[0001] This utility model relates to the field of heat-resistant pad technology, specifically to an anti-loosening mechanism for heat-resistant pads in heating furnaces. Background Technology

[0002] In industrial production, heating furnaces, as key heat processing equipment, are widely used in many processes such as metal smelting, ceramic firing, and material heat treatment. However, the traditional method of fixing heat-resistant pads in heating furnaces has many drawbacks. On the one hand, conventional connection methods rely heavily on simple bolt and nut tightening. Under the high-temperature environment generated by the prolonged operation of the heating furnace, the metal components expand due to heat, and the tightening force between the bolts and nuts decreases significantly, making loosening very easy. At the same time, the continuous vibration that inevitably occurs during the operation of the heating furnace constantly impacts the heat-resistant pads and their connectors, further exacerbating the risk of loosening. On the other hand, previous fixing structures often only limit movement in one direction, making it difficult to simultaneously meet the stability requirements in both horizontal and vertical directions. Once the heat-resistant pads loosen, it will not only cause the position of the workpiece they support to shift, affecting the consistency of product quality, but may also lead to equipment failure, causing production interruptions and increasing maintenance costs and downtime. For example, in metal forging furnaces, if the heat-resistant pads become loose, the heated metal billets may slip, damaging the furnace's internal structure and even endangering operator safety. In fine ceramic firing furnaces, loose pads can cause uneven heating of ceramic products, resulting in a large number of defective products. Given these problems, there is an urgent need to develop a novel anti-loosening mechanism that can effectively cope with high-temperature and vibration conditions, ensuring the stability and reliability of the heat-resistant pads, to meet the requirements of modern industrial production for efficient and safe operation of heating furnaces. Utility Model Content

[0003] The purpose of this invention is to provide an anti-loosening mechanism for heat-resistant pads in heating furnaces, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An anti-loosening mechanism for a heat-resistant pad block in a heating furnace includes a receiving base, a wedge block movably connected to the upper surface of the receiving base, a heat-resistant pad block movably connected to the outer wall of the wedge block, and a wedge groove formed on the bottom surface of the heat-resistant pad block, the wedge groove being adapted to and inserted into the outer wall of the wedge block near the top.

[0006] The wedge block has an installation hole at its top, and the heat-resistant pad has a threaded hole at its top. A pad fixing bolt is threadedly connected to the inner wall of the threaded hole, and the outer wall of the pad fixing bolt near its bottom end is threadedly connected to the inner wall of the installation hole.

[0007] Both sides are provided with elastic clamping components. The elastic clamping components are used to clamp the heat-resistant pad, buffer vibration, stabilize the heat-resistant pad in the horizontal direction, and ensure that it will not move laterally due to vibration or thermal expansion and contraction during the operation of the heating furnace. The elastic clamping components include clamping plates, one end of which is rotatably connected to a mounting base through a high-temperature resistant pin seat.

[0008] A further improvement of the present invention is that: an elastic clamping piece is fixedly connected to the side of the clamping plate near the heat-resistant pad, a high-temperature resistant rubber pad is fixedly connected to the side of the elastic clamping piece near the heat-resistant pad, and a side arc groove adapted to the elastic clamping piece is provided on the side of the heat-resistant pad.

[0009] A further improvement of this utility model is that a limiting arc-shaped protrusion is fixedly connected to the side of the mounting base near the clamping plate, and the side of the limiting arc-shaped protrusion away from the mounting base overlaps with the side of the clamping plate.

[0010] A further improvement of this utility model is that a bottom column is fixedly connected to the bottom surface of the clamping plate near one end, and an installation groove is provided on the upper surface of the wedge block near one side, with the bottom end of the bottom column being movably connected to the inner wall of the installation groove.

[0011] A further improvement of this utility model is that: a base mounting hole is provided on one side of the receiving base, a reinforcing horizontal plate is fixedly connected to the bottom surface of the wedge block, a base mounting bolt is provided on one side of the reinforcing horizontal plate, and the base mounting bolt is threadedly connected to the inner wall of the base mounting hole through one end of the reinforcing horizontal plate.

[0012] A further improvement of this utility model is that the number of mounting seats is two sets, and the two sets of mounting seats are symmetrically distributed on both sides of the heat-resistant pad.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] This invention provides an anti-loosening mechanism for heat-resistant pads in heating furnaces. Through the synergistic action of an elastic clamping component and a wedge-shaped self-locking structure, it provides stable support for the heat-resistant pads in both horizontal and vertical directions. Horizontally, the elastic clamping piece, made of a high-temperature resistant elastic alloy, works in conjunction with a high-temperature resistant rubber pad, using elasticity and friction to restrict pad displacement from both sides and buffer vibration. Vertically, the ceramic matrix composite wedge, with its self-locking angle design, tightly engages with the wedge groove of the pad when bearing weight, resisting thermal expansion and contraction and vibration impacts. This ensures the stability of the heat-resistant pad from all angles, thereby guaranteeing that the workpiece it supports remains in place under the complex and harsh operating conditions of the heating furnace. This greatly improves the stability of the heating furnace operation and reduces the risk of equipment failure and production interruption caused by pad loosening.

[0015] This utility model provides an anti-loosening mechanism for heat-resistant pads in heating furnaces. The structural design fully considers ease of operation. The supporting base can be fixed to the bottom of the heating furnace using bolts or welding. The wedge block is also connected to the supporting base, and the heat-resistant pad is connected to the wedge block via bolts. The installation steps for each component are clear, the connections are tight, and it is easy to operate. Meanwhile, key components such as the elastic clamping plate and wedge block are made of high-quality materials, ensuring durability. Furthermore, due to its modular design and convenient connection method, maintenance and replacement are relatively simple in the event of wear or failure, effectively reducing equipment maintenance costs and downtime, and improving production efficiency.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-5As shown, this utility model provides an anti-loosening mechanism for a heat-resistant pad block for a heating furnace, including a receiving base 1, a wedge block 2 movably connected to the upper surface of the receiving base 1, a heat-resistant pad block 3 movably connected to the outer wall of the wedge block 2, and a wedge groove 12 opened on the bottom surface of the heat-resistant pad block 3, the wedge groove 12 being adapted to be inserted into the outer wall of the wedge block 2 near the top.

[0026] The top of the wedge block 2 is provided with a mounting hole 10, and the top of the heat-resistant pad block 3 is provided with a pad thread hole 13. The inner wall of the pad thread hole 13 is threaded with a pad fixing bolt 14, and the outer wall of the pad fixing bolt 14 near the bottom end is threaded with the inner wall of the mounting hole 10.

[0027] Both sides of 3 are provided with elastic clamping components. The elastic clamping components are used to clamp the heat-resistant pad 3, buffer vibration, stabilize the heat-resistant pad 3 in the horizontal direction, and ensure that it will not move laterally due to vibration or thermal expansion and contraction during the operation of the heating furnace. The elastic clamping components include a clamping plate 4, and one end of the clamping plate 4 is rotatably connected to the mounting base 5 through a high-temperature resistant pin seat 6.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, an elastic clamping piece 17 is fixedly connected to the side of the clamping plate 4 near the heat-resistant pad 3, and a high-temperature resistant rubber pad 18 is fixedly connected to the side of the elastic clamping piece 17 near the heat-resistant pad 3. A side arc groove 11 adapted to the elastic clamping piece 17 is opened on the side of the heat-resistant pad 3.

[0030] The mounting base 5 is fixedly connected to the side of the clamping plate 4 with a limiting arc-shaped protrusion 7. The side of the limiting arc-shaped protrusion 7 away from the mounting base 5 overlaps with the side of the clamping plate 4.

[0031] A bottom post 8 is fixedly connected to the bottom surface of the clamping plate 4 near one end, and an installation groove 9 is opened on the upper surface of the wedge block 2 near one side. The bottom end of the bottom post 8 is movably connected to the inner wall of the installation groove 9.

[0032] A base mounting hole 15 is provided on one side of the base 1. A reinforcing horizontal plate is fixedly connected to the bottom surface of the wedge block 2. A base mounting bolt 16 is provided on one side of the reinforcing horizontal plate. One end of the base mounting bolt 16 movably passes through the reinforcing horizontal plate and is threadedly connected to the inner wall of the base mounting hole 15.

[0033] There are two sets of mounting bases 5, which are symmetrically distributed on both sides of the heat-resistant pad block 3.

[0034] The working principle of the anti-loosening mechanism for the heat-resistant pads of this heating furnace will be explained in detail below.

[0035] like Figure 1-5As shown, first connect the receiving base 1 to the predetermined position at the bottom of the heating furnace, and then fix it with bolts or welding.

[0036] After the base 1 is installed, the bottom of the wedge block 2 is aligned with the top of the base 1, and then the base mounting bolts 16 are aligned with the base mounting holes 15 to fix the wedge block 2 and the base 1.

[0037] Subsequently, the wedge-shaped groove 12 at the bottom of the heat-resistant pad 3 is aligned with the wedge-shaped block 2, and then slowly slid in along the top plane of the wedge-shaped block 2 so that the wedge-shaped groove 12 and the wedge-shaped block 2 are completely matched.

[0038] The clamping plate 4 is then connected to the mounting base 5 via the high-temperature resistant pin seat 6. The high-temperature resistant pin seat 6 includes a pin tube fixed to one side of the clamping plate 4 and a removable high-temperature resistant pin. At this time, the elastic clamping piece 17 will fit against the side arc groove 11.

[0039] Finally, install the pad fixing bolt 14 from the pad threaded hole 13 to complete the installation of the device by fixing the heat-resistant pad 3 and the wedge block 2.

[0040] During use, the elastic clamping piece 17 is made of a high-temperature resistant elastic alloy such as a nickel-based alloy. One end of the clamping piece is flexibly rotatable within the constraint of the clamping plate 4, while the other end is a free end. A high-temperature resistant rubber pad 18 is adhered to the inner side of the free end, tightly fitting against the side of the heat-resistant pad 3. When the heating furnace is running, the clamping piece applies a stable clamping force to the pad using its own elasticity, while the high-temperature resistant rubber pad 18 further increases the friction, firmly "holding" the pad from both sides, effectively limiting the horizontal displacement tendency of the pad caused by vibration or thermal expansion and contraction. Even under strong vibration, this elastic clamping structure can buffer the impact, continuously maintaining the horizontal stability of the pad and ensuring that the workpiece it supports is not disturbed.

[0041] The wedge block 2 is made of ceramic matrix composite material, which is not only resistant to high temperature and high strength, but also has a low coefficient of friction, which makes it easy for the wedge groove 12 at the bottom of the heat-resistant pad block 3 to slide in smoothly.

[0042] When the heat-resistant pad 3 bears weight, the vertical pressure causes the wedge block 2 to engage tightly with the wedge groove 12, forming a self-locking state. Whether it is the upward force generated by thermal expansion or the instantaneous vertical impact caused by vibration, the wedge block 2 can firmly "lock" the pad, keeping it fixed in the vertical direction and eliminating the risk of it coming off.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
