Description

Technical Field

[0001] This utility model relates to the field of sintering trolley technology, specifically to a leak-proof component that works with a sintering trolley. Background Technology

[0002] In the sintering process of steel production, such as Figure 6 As shown, the sintering machine forms a circular running system by connecting the side plates 1 of multiple sintering trolleys end to end. The sintering trolleys, as the core carriers of the sintering mixture, need to complete the cycle of feeding, ignition, sintering, cooling, and unloading sequentially on the track. To ensure the flexibility of the sintering trolleys and avoid structural damage caused by rigid collisions between adjacent sintering trolleys under hot conditions, existing technologies typically leave an installation gap 2 between the side plates 1 of adjacent sintering trolleys. However, material on the sintering trolleys can leak through this gap 2, thus affecting sintering quality and output.

[0003] To address this issue, Chinese patent document CN220689788U discloses a leak-proof sintering trolley. A set of fan-shaped splicing mechanisms is installed between the edges of two adjacent main bodies. These fan-shaped plates can block gaps between adjacent main bodies, increasing the leak-proof effect and effectively improving the sintering quality and yield. However, because the sintering trolley needs to run continuously along a circular track, and the track develops local bulges, depressions, or uneven joints after long-term use, the sintering trolley experiences bumps during operation. The wheels of adjacent sintering trolleys cannot synchronously cope with track unevenness, inevitably leading to misalignment of the side plates of adjacent sintering trolleys. Furthermore, the fan-shaped plates, fixed to one side plate and inserted into the adjacent side plate, experience pulling and squeezing due to the relative movement of the side plates. Stress concentration occurs at the splicing points of the fan-shaped plates, and fatigue from repeated long-term stress can easily cause them to break. Therefore, the structure of the aforementioned patent suffers from a short lifespan. Utility Model Content

[0004] To address the short lifespan of existing leak-proof structures, this invention provides a leak-proof material assembly that works in conjunction with a sintering trolley, thereby extending the service life of the leak-proof assembly.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a leak-proof component that works with a sintering trolley, including a mounting plate and a blocking plate for closing the installation gap between adjacent sintering trolleys. The mounting plate is overlapped on the side plate of the sintering trolley by an overlapping block. The blocking plate is located between the mounting plate and the side plate, and the blocking plate is connected to the mounting plate by multiple spring clips. During the movement of the sintering trolley, the blocking plate is attached to the side plate.

[0006] As a further optimization of the anti-leakage component for use with a sintering trolley, the mounting plate is provided with a through groove, and the blocking plate is provided with a rod passing through the through groove. The through groove is rectangular, and both the length and width of the through groove are greater than the diameter of the rod.

[0007] As a further optimization of the anti-leakage component for use with a sintering trolley, the portion of the insert rod that protrudes from the through slot is provided with an anti-detachment plate.

[0008] As a further optimization of the anti-leakage component for use with a sintering trolley, the mounting plate is fixedly connected to a mounting rod, and the overlapping block includes a first part and a second part that are perpendicular to each other. The first part is fixedly connected to one end of the mounting rod, and an overlapping space is formed between the first part and the second part to accommodate the side plate.

[0009] As a further optimization of the anti-leakage component for use with a sintering trolley, there is a gap between the baffle plate and the mounting rod.

[0010] As a further optimization of the anti-leakage component for use with a sintering trolley, the spring is configured as C-shaped and is fixedly connected to the blocking plate and the mounting plate by several bolts.

[0011] As a further optimization of the anti-leakage component for use with a sintering trolley, the end of the spring is fixedly connected to a pad, and the pad is fixedly connected to the mounting plate by the bolt.

[0012] As a further optimization of the anti-leakage component for use with a sintering trolley, the ends of the spring pieces are respectively inserted into the blocking plate and the mounting plate.

[0013] As a further optimization of the anti-leakage component for use with a sintering trolley, the spring sheet is evenly distributed between the baffle plate and the mounting plate in the vertical direction.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1) By setting up an installation plate and a blocking plate for sealing the installation gap between adjacent sintering trolleys, when the sintering trolleys move to the track joints, protrusions, etc., causing bumps and inevitably resulting in height misalignment of the side plates of adjacent sintering trolleys, the overlapping block always overlaps on one of the side plates. Therefore, the installation plate will move with this side plate through the overlapping block. Furthermore, because the blocking plate is fixedly connected to the installation plate through a spring clip, the spring clip can always push the blocking plate, so that the blocking plate fits against the surface of the side plate to seal the installation gap and prevent material leakage.

[0015] 2) The baffle plate of this utility model does not need to be repeatedly bent and deformed, so it will not break. It can ensure that the installation gap can be continuously sealed, while having a longer service life, and does not need to be replaced frequently and has a lower cost.

[0016] 3) This utility model can be combined with existing sintering trolleys without the need to purchase new sintering trolleys or modify existing ones; it can be put into use directly without downtime for modification, thereby significantly reducing the cost of use and the risk of production stagnation caused by equipment improvement.

[0018] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the materials of the overlapping block 3, the blocking plate 4, the mounting plate 5, the mounting rod 6, the insert rod 8, the anti-detachment plate 9, the spring piece 12, the bolt 13, and the pad 14.

[0019] Example 1 A leak-proof assembly for use with a sintering trolley, such as Figures 1 to 5 As shown, it includes a mounting plate 5 and a baffle plate 4 for closing the mounting gap 2 between adjacent sintering trolleys. The mounting plate 5 is overlapped on the side plate 1 of the sintering trolley by an overlap block 3. The baffle plate 4 is located between the mounting plate 5 and the side plate 1, and the baffle plate 4 is connected to the mounting plate 5 by multiple spring pieces 12. During the movement of the sintering trolley, the baffle plate 4 is attached to the side plate 1.

[0020] When the sintering trolley travels to locations with bumps or uneven surfaces, causing unavoidable misalignment of the side plates 1 of adjacent sintering trolleys, the overlapping block 3 always overlaps one of the side plates 1. Therefore, the mounting plate 5 moves with this side plate 1 via the overlapping block 3. Since the blocking plate 4 is fixedly connected to the mounting plate 5 via the spring piece 12, the spring piece 12 can always push the blocking plate 4, keeping it pressed against the surface of the side plate 1 to seal the installation gap 2 and prevent material leakage. During stable operation of the sintering trolley, the mounting plate 5 remains stably overlapped with the side plate 1 via the overlapping block 3. Therefore, the blocking plate 4 can always press against the surface of the side plate 1 to seal the installation gap 2 and prevent material leakage. Furthermore, compared to the leak-proof sintering trolley disclosed in patent document "CN220689788U" in the prior art, the blocking plate 4 of this utility model does not require repeated bending and deformation, thus preventing breakage. It ensures continuous sealing of the installation gap 2, has a longer service life, does not require frequent replacement, and is less costly. Furthermore, this invention can be integrated with existing sintering trolleys without the need to purchase new sintering trolleys or modify existing ones. It can be put into use directly without downtime for modifications, thus significantly reducing operating costs and the risk of production stoppages caused by equipment upgrades.

[0021] The mounting plate 5 is attached to the side plate 1 of the sintering trolley via the overlapping block 3. The overlapping position of the overlapping block 3 is set close to the installation gap 2 between adjacent sintering trolleys to ensure that the contact area of ​​the baffle plate 4 can completely cover the installation gap 2 when the baffle plate 4 is assembled later. An assembly space is reserved between the mounting plate 5 and the side plate 1 to provide sufficient space for the installation of the spring piece 12 and subsequent elastic deformation. The length of the baffle plate 4 is greater than the length of the installation gap 2, and the width of the baffle plate 4 is greater than the width of the installation gap 2 to ensure that the baffle plate 4 can still completely seal the installation gap 2 under dynamic working conditions to avoid material leakage.

[0022] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments: Example 2 This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2As shown, to further prevent the baffle plate 4 from falling off and thus failing to seal the installation gap 2, a through groove 7 is provided on the mounting plate 5. A rod 8 is provided on the baffle plate 4, passing through the through groove 7. The through groove 7 is rectangular, with both its length and width exceeding the diameter of the rod 8. The through groove 7's larger dimensions allow the rod 8 to move within a small range inside the groove 7. When the baffle plate 4 vibrates with the trolley, it can cause the rod 8 to vibrate synchronously, preventing the baffle plate 4 from being restricted in its movement and also preventing the rod 8 and the through groove 7 from squeezing against each other, causing deformation or even damage. An anti-detachment plate 9 is provided on the portion of the rod 8 that extends out of the through groove 7.

[0023] Example 3 This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 3 As shown, the mounting plate 5 is fixedly connected to the mounting rod 6, and the overlapping block 3 includes a first part 10 and a second part 11 that are perpendicular to each other. The first part 10 is fixedly connected to one end of the mounting rod 6, and an overlapping space is formed between the first part 10 and the second part 11 to accommodate the side plate 1.

[0024] After the mounting rod 6 and the mounting plate 5 are fixedly connected, the first part 10 of the overlapping block 3 is installed on the top of the mounting rod 6. The first part 10 and the second part 11 are perpendicular to each other to form an L-shape. The side plate 1 is located in the overlapping space between the first part 10 and the second part 11 to accommodate the side plate 1. At this time, the fixing between the side plate 1, the mounting rod 6 and the mounting plate 5 is completed, and the overlapping block 3 is easy to install.

[0025] However, in order to prevent the mounting rod 6 from obstructing the small-range movement of the baffle plate 4 with the trolley, there is a gap of 15 between the baffle plate 4 and the mounting rod 6.

[0026] Example 4 This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 4 As shown, the spring piece 12 is C-shaped and is fixedly connected to the blocking plate 4 and the mounting plate 5 by a number of bolts 13. The two ends of the spring piece 12 are fixedly connected to the mounting plate 5 by bolts 13, and the middle part of the spring piece 12 contacts the blocking plate 4, and the middle part of the spring piece 12 is fixedly connected to the blocking plate 4 by bolts 13.

[0027] Example 5 This embodiment is an improvement on embodiment 4. Its main structure is the same as that of embodiment 4, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 4As shown, in order to facilitate the connection between the spring piece 12 and the blocking plate 4 and the mounting plate 5, a pad 14 is fixedly connected to the end of the spring piece 12. The pad 14 fits against the blocking plate 4 and the mounting plate 5, and the pad 14 is fixedly connected to the mounting plate 5 by the bolt 13.

[0028] Example 6 This embodiment is an improvement on embodiment 4. Its main structure is the same as embodiment 4, but the improvement lies in the following: to facilitate the connection between the spring piece 12 and the blocking plate 4 and the mounting plate 5, the end of the spring piece 12 is inserted into both the blocking plate 4 and the mounting plate 5. The end of the spring piece 12 is bent and inserted into the pre-drilled holes on the blocking plate 4 and the mounting plate 5.

[0029] Example 7 This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 3 As shown, in order to further ensure the overall force balance of the baffle plate 4, the spring pieces 12 are evenly distributed between the baffle plate 4 and the mounting plate 5 in the vertical direction.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
