Description

Technical Field

[0001] This utility model belongs to the field of sealant technology, specifically relating to a transport device for graphite gaskets. Background Technology

[0002] Graphite gaskets, as key sealing components in industrial pipelines, valves, and pressure vessels, play an irreplaceable role in petrochemical, power, and nuclear energy industries. With the trend towards larger and more efficient industrial equipment, the size of graphite gaskets is constantly increasing (typically 50-200cm), placing higher demands on their transportation and storage. Traditional flat-laying methods suffer from low space utilization, inconvenient handling, and are no longer sufficient to meet the needs of modern industrial production. Large graphite gaskets are usually circular rings with a relatively large radius; if laid flat, they occupy a large area and require a large moving device, resulting in inconvenient movement and low space utilization. Therefore, improvements are necessary to address these issues. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a transportation device for graphite gaskets. By setting a T-shaped guide device fixed to a vertical plate and a suspended positioning support assembly on the guide device, the graphite gaskets are changed from being laid flat to being suspended, reducing the space occupied by the mobile trolley and significantly improving space utilization. The guide device has guide grooves evenly distributed on the front and rear side walls, which can install multiple sets of suspended positioning support assemblies. Each set of assemblies can suspend and support multiple graphite gaskets of the same model, making full use of the areas on both sides of the guide device. This is conducive to uniform load distribution, meeting the needs of batch transportation, and improving transportation efficiency. The suspended positioning support assembly is height-adjustable and fixed on the guide groove. Its position can be adjusted according to the specifications of the graphite gaskets to adapt to the transportation of gaskets of different sizes and the same model, improving the versatility of the device. Combined with a mobile trolley with push-pull rods, it effectively solves the problem of inconvenient movement of traditional large mobile devices.

[0004] The technical solution adopted by this utility model is as follows: a transportation device for graphite sealing gaskets, including a mobile trolley. A vertical plate is fixed at the left edge of the upper surface of the mobile trolley, and a U-shaped push-pull rod extending outward is fixed on the outer wall of the vertical plate. A guide device is provided in the middle of the upper surface of the mobile trolley, which is perpendicularly fixed to the vertical plate to form a T-shaped structure. Multiple guide grooves are evenly distributed on the front and rear side walls of the guide device, and multiple sets of suspended positioning support components adapted to the guide grooves are height-adjustably fixed on the guide device. Each set of suspended positioning support components provides suspension support and positioning for multiple graphite sealing gaskets of the same model.

[0005] The guiding device includes multiple guide posts and vertical plates. The multiple guide posts are vertically fixed at the center line of the upper end face of the mobile trolley. Two vertical plates are fixed between the guide posts and the vertical plates, between two adjacent guide posts, and between the rightmost guide post and the right side edge of the mobile trolley. The guide posts have guide grooves on both the front and rear side walls. Multiple positioning holes are symmetrically distributed on both sides of the guide grooves on the front and rear side walls of the guide posts. The sliding block end is adapted to the suspended positioning support assembly in the guide groove and is positioned on the guide post by the insertion rod adapted to the positioning hole.

[0006] Furthermore, a rubber pad is fixed on the outer wall of the vertical plate, which contacts the graphite sealing gasket suspended on the innermost side of the suspended positioning support assembly.

[0007] Furthermore, the suspended positioning support assembly includes an upper suspended positioning support assembly whose arc-shaped positioning surface contacts the upper inner ring wall of the graphite sealing gasket, and a lower suspended positioning support assembly whose arc-shaped positioning surface contacts the lower outer ring wall of the graphite sealing gasket.

[0008] Furthermore, the upper-suspended positioning support assembly includes an L-shaped cantilever and a slider. The L-shaped cantilever is an L-shaped structure composed of an arc-shaped arm and a connecting plate located at the inner end of the arc-shaped arm. The middle of the outer wall of the connecting plate is provided with a slider that is adapted to the guide groove, and the connecting plate surface is provided with through holes corresponding to the positions of two positioning holes at the same height on the guide post. Multiple graphite sealing gaskets of the same type are suspended from the inside to the outside on the arc-shaped arm of the L-shaped cantilever.

[0009] Furthermore, the lower-suspended positioning support assembly and the upper-suspended positioning support assembly have the same structure. In the upper-suspended positioning support assembly, the arc-shaped arm of the L-shaped cantilever is an arc-shaped convex arm adapted to the inner ring wall of the graphite gasket, while in the lower-suspended positioning support assembly, the arc-shaped arm of the L-shaped cantilever is an arc-shaped concave arm adapted to the lower outer ring wall of the graphite gasket. The outer ends of the arc-shaped concave arm of the L-shaped cantilever in the lower-suspended positioning support assembly and the arc-shaped convex arm of the L-shaped cantilever in the upper-suspended positioning support assembly are symmetrically fixed with arc-shaped positioning ridges for preventing the graphite gasket from falling off.

[0010] Advantages of this utility model compared to the prior art:

[0011] 1. This technical solution changes the traditional flat placement of graphite sealing gaskets to a suspended placement by setting up a T-shaped guide device that is fixed to the upright plate and a suspended positioning support component on the guide device, thereby reducing the occupation of the planar space of the mobile trolley and significantly improving the space utilization rate.

[0012] 2. The guide device of this technical solution has guide grooves evenly distributed on the front and rear side walls, which can install multiple sets of suspended positioning support components. Each set of components can suspend and support multiple graphite gaskets of the same model, making full use of the area on both sides of the guide device. This is conducive to uniform load distribution, meeting the needs of batch transportation, and improving transportation efficiency.

[0013] 3. The suspended positioning support component of this technical solution is height-adjustable and fixed on the guide groove. Its position can be adjusted according to the specifications of the graphite sealing gasket, which can adapt to the transportation of gaskets of different sizes and the same model, improve the versatility of the device. When combined with a mobile trolley with push-pull rod, it effectively solves the problem of inconvenient movement of traditional large mobile devices.

[0014] 4. Under the premise that the upper inner ring wall and lower outer ring wall of the graphite gasket are in contact with the arc-shaped arms of the upper and lower suspended positioning support components respectively, the graphite gasket is provided with arc-shaped positioning protrusions at the ends of the arc-shaped arms in the upper and lower suspended positioning support components. This is specifically designed to prevent the graphite gasket from falling off. During transportation, it can adapt to complex transportation environments such as bumps and turns, reducing the risk of the graphite gasket falling off. Attached Figure Description

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0020] Transport devices for graphite gaskets, such as Figure 1-2 As shown, the device includes a mobile trolley 1, characterized in that: a vertical plate 2 is fixed at the left edge of the upper surface of the mobile trolley 1, and a U-shaped push-pull rod 3 extending outward is fixed on the outer wall of the vertical plate 2; a guide device 4 is provided in the middle of the upper surface of the mobile trolley 1, which is perpendicularly fixed to the vertical plate 2 to form a T-shaped structure; multiple guide grooves 4-3 are evenly distributed on the front and rear side walls of the guide device 4, which are vertically arranged along their length direction; and multiple sets of suspended positioning support components adapted to the guide grooves 4-3 are height-adjustably fixed on the guide device 4, and each set of suspended positioning support components provides suspension support and positioning for multiple graphite gaskets of the same model.

[0021] In the above structure, by setting a T-shaped guide device 4 fixedly connected to the upright plate 2 and a suspended positioning support assembly on the guide device 4, the graphite sealing gasket is changed from the traditional flat placement to a suspended placement, which reduces the occupation of the planar space of the mobile trolley 1 and significantly improves the space utilization rate. The guide device 4 has guide grooves 4-3 evenly distributed on the front and rear side walls, which can install multiple sets of suspended positioning support assemblies. Each set of assemblies can suspend and support multiple graphite sealing gaskets of the same model, making full use of the areas on both sides of the guide device 4. This is conducive to uniform load distribution, meets the needs of batch transportation, and improves transportation efficiency. The suspended positioning support assembly is fixed to the guide groove 4-3 with adjustable height. The position can be adjusted according to the specifications of the graphite sealing gasket, adapting to the transportation of gaskets of different sizes and the same model, improving the versatility of the device. Combined with the mobile trolley with push-pull rod, it effectively solves the problem of inconvenient movement of traditional large mobile devices.

[0022] The specific structure of the guiding device 4 is as follows: The guiding device 4 includes multiple guide posts 4-1 and vertical plates 4-2. The multiple guide posts 4-1 are vertically fixed at the center line of the upper end face of the moving trolley 1. Two vertical plates 4-2, respectively located on the same plane as the front and rear side walls of the guide posts 4-1, are fixed between the guide posts 4-1 and the vertical plates 2, between two adjacent guide posts 4-1, and between the rightmost guide post 4-1 and the right side edge of the moving trolley 1. Guide grooves 4-3 are formed on both the front and rear side walls of the guide posts 4-1. Multiple symmetrically distributed positioning holes 4-4 are located on both sides of the guide groove 4-3 on the front and rear side walls. The sliding block end, fitted into the guide groove 4-3, is positioned on the guide post 4-1 via a rod that mates with the positioning hole 4-4. Multiple guide posts 4-1 are fixed to the moving trolley via vertical plates 4-2, forming a multi-point supported rigid frame. This distributes the weight load of the suspended graphite gasket, enhancing its resistance to deformation and enabling it to stably support larger gaskets, reducing the risk of structural damage during long-term use and extending the device's service life. Figure 1 As shown, smaller graphite gaskets that can be fitted inside larger graphite gaskets can be installed within the annular space of the largest diameter graphite gasket suspended in this structure, thus making full use of the installation space. The suspended positioning support assembly can be replaced according to the specific model of the graphite gasket.

[0023] In the above structure, the guide device 4 consists of multiple guide posts 4-1 and vertical plates 4-2. The guide posts 4-1 are distributed along the centerline of the moving trolley 1, and the vertical plates 4-2 are fixed between adjacent guide posts 4-1 and between the guide posts 4-1 and the vertical plates 2 / right side plates of the moving trolley 1. This improves the support strength of the guide device 4 and provides installation space for fixing the rubber pads 4-5. The double-sided suspension layout of the guide device 4 makes full use of the lateral space of the moving trolley 1 and avoids the waste of space and uneven load distribution caused by single-sided suspension.

[0024] The positioning hole 4-4 is a through hole penetrating the front and rear side walls of the guide post 4-1, and the insertion rod passes through the corresponding through hole and positioning hole 4-4 at the slider end of the suspended positioning support assembly, realizing the height-adjustable connection between the suspended positioning support assembly and the guide post 4-1. The insertion rod can be a screw rod with a central optical axis and threaded ends. After insertion, nuts are used to fit and connect to both ends of the insertion rod, realizing the reliable fixed connection of the suspended positioning support assembly on the guide post 4-1. Each set of suspended positioning support assemblies can be independently adjusted in height according to the size of the graphite gasket (such as diameter and thickness), and the rigid connection between the insertion rod and the positioning hole 4-4 can ensure the stability of the position after adjustment and avoid displacement caused by vibration during transportation.

[0025] A rubber pad 4-5 is fixed on the outer wall of the vertical plate 4-2, which contacts the graphite sealing gasket suspended on the innermost side of the suspended positioning support assembly; the rubber pad 4-5 is fixed on the outer wall of the vertical plate 4-2 connected to the guide column 4-1, and it is in direct contact with the graphite sealing gasket suspended on the innermost side of the upper suspended positioning support assembly 5; the elastic properties of the rubber pad 4-5 can buffer the vibration or collision during transportation, avoid the graphite sealing gasket from directly rubbing against the rigid structure, which would cause edge wear or surface damage, and protect the sealing performance of the graphite sealing gasket (especially important for the precision of large gaskets).

[0026] The specific structure of the suspended positioning support assembly is as follows: The suspended positioning support assembly includes an upper suspended positioning support assembly 5 whose arc-shaped positioning surface contacts the inner ring wall of the upper end of the graphite sealing gasket, and a lower suspended positioning support assembly 6 whose arc-shaped positioning surface contacts the outer ring wall of the lower end of the graphite sealing gasket; wherein, the upper suspended positioning support assembly 5 includes an L-shaped cantilever 5-1 and a slider 5-2, the L-shaped cantilever 5-1 is an L-shaped structure composed of an arc-shaped arm and a connecting plate located at the inner end of the arc-shaped arm, and the middle of the outer wall of the connecting plate is provided with a guide. The slider 5-2 is adapted to the groove 4-3, and the connecting plate surface has through holes corresponding to the positions of two positioning holes 4-4 at the same height as the guide post 4-1. Multiple graphite gaskets of the same model are suspended from the inside out on the arc-shaped arm of the L-shaped cantilever 5-1. Specifically, the lower-suspended positioning support assembly 6 and the upper-suspended positioning support assembly 5 have the same structure. In the upper-suspended positioning support assembly 5, the arc-shaped arm of the L-shaped cantilever 5-1 is an arc-shaped convex arm adapted to the inner ring wall of the graphite gasket, while the lower-suspended positioning support assembly... The arc-shaped arm of the L-shaped cantilever 5-1 in component 6 is an arc-shaped concave arm adapted to the lower outer ring wall of the graphite gasket. The outer ends of both the arc-shaped concave arm of the L-shaped cantilever 5-1 in the lower suspended positioning support assembly 6 and the arc-shaped convex arm of the L-shaped cantilever 5-1 in the upper suspended positioning support assembly 5 are symmetrically fixed with arc-shaped positioning ridges 5-3 for preventing the graphite gasket from detaching. The upper inner ring wall and lower outer ring wall of the graphite gasket respectively contact and support the arc-shaped arms of the upper suspended positioning support assembly 5 and the lower suspended positioning support assembly 6. Under this premise, by providing arc-shaped positioning protrusions 5-3 at the ends of the arc-shaped arms in both the upper-suspended positioning support assembly 5 and the lower-suspended positioning support assembly 6, it is specifically designed to prevent the graphite gasket from falling off. During transportation, it can adapt to complex transportation environments such as bumps and turns, reducing the risk of the graphite gasket falling off and ensuring high transportation safety and reliability. Among them, depending on the model of the graphite gasket, an arc-shaped rubber pad can be added to the arc-shaped concave arm in the lower-suspended positioning support assembly 6 to ensure contact support for the lower outer ring wall of the graphite gasket.
