Description

Technical Field

[0001] This utility model relates to the field of assembly mechanism technology, and in particular to a modular assembly mechanism for attaching pressure-resistant plates to F4 storage tanks. Background Technology

[0002] The F4 pressure-resistant tank (PTFE-lined tank) combines the structural strength of steel with the corrosion resistance of F4 material. Its smooth surface is not prone to scaling, supports quick cleaning and component replacement, and can be customized in volume and shape (vertical / horizontal). It is also equipped with accessories such as level gauges and thermometers, and is suitable for chemical, pharmaceutical and other industries where pressure and corrosion protection are both important considerations.

[0003] In the prior art, Chinese patent CN221666365U discloses a modular assembly mechanism for controlled atmosphere equipment. The height of the modular assembly box can be easily adjusted using a lifting cylinder installed at the bottom, enabling quick and flexible assembly operations. The box door makes opening and closing the assembly box more convenient and facilitates maintenance and replacement of the various modules inside. However, in practical applications, the F4 pressure-resistant tank is large and difficult to transport, especially the vertical tank, which needs to be tilted for transport safety. Therefore, existing F4 pressure-resistant tanks are modularly assembled, with some components transported to the site for installation. However, the vertical tank is quite tall after being placed on the ground, requiring the use of ladders or other tools to install the upper assembly components, which is inconvenient. Therefore, we disclose a modular assembly mechanism for F4 pressure-resistant tanks. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a modular assembly mechanism for attaching pressure-resistant plates to F4 storage tanks to solve the problem of inconvenient tank assembly.

[0005] Based on the above objectives, this utility model provides a modular assembly mechanism for a pressure-resistant plate-attached F4 storage tank, including a storage tank body. Several connecting strips are movably engaged with the outer wall of the storage tank body. A first fixing strip and a second fixing strip are movably sleeved on the outer wall of each connecting strip. The adjacent ends of the first fixing strip and the second fixing strip are rotatably connected. A hydraulic cylinder is fixedly connected to the bottom end of the first fixing strip. A connecting rod is sleeved through the other end of the first fixing strip. A threaded groove is fixedly opened at one end of the connecting rod. A fastening nut is threadedly connected to the connecting rod through the threaded groove. A limit block is fixedly connected to the other end of the connecting rod. A connecting hole is opened at the other end of the second fixing strip. A limit groove is opened at one end of the connecting hole. Both the limit groove and the connecting hole are movably sleeved with the limit block. The connecting rod passes through the connecting hole and the limit groove.

[0006] Preferably, the output end of the hydraulic cylinder is fixedly connected to the first fixing bar, and both the first fixing bar and the second fixing bar are arc-shaped.

[0007] Preferably, a silicone strip is fixedly connected to the inner wall of the connecting strip, and the silicone strip is tightly fitted to the outer wall of the tank body. Both the connecting strip and the silicone strip are C-shaped.

[0008] Preferably, the limiting block is rectangular, the connecting hole and the limiting groove have the same shape, the connecting hole and the limiting groove are connected, the connecting hole and the limiting groove are connected in a cross shape, and the connecting rod is T-shaped.

[0009] Preferably, the inner walls of both the second fixing strip and the first fixing strip are provided with a plurality of movable grooves. One end of each movable groove is fixedly connected to a spring piece, and one end of each spring piece is fixedly connected to a connecting shell. A rotating ball is movably engaged in the inner cavity of the connecting shell, and the rotating ball extends to one side outside the second fixing strip and fits against the outer wall of the connecting strip.

[0010] Preferably, the side of the connecting shell is C-shaped, and the connecting shell is movably connected to the movable groove.

[0011] Preferably, the sides of both the second fixing strip and the first fixing strip are U-shaped, and the connecting strip is rotatably connected to the middle of the first fixing strip and the second fixing strip.

[0012] The beneficial effects of this utility model are as follows: By restricting the movement direction of the connecting rod by the first fixing bar, the fastening nut can rotate along the threaded groove at the upper end of the connecting rod. By fixing the connecting rod and the limiting block relative to each other, the connecting rod drives the limiting block to pass through the connecting hole and rotate 90 degrees before engaging with the limiting groove. Then, by rotating the fastening nut, the position of the first fixing bar and the second fixing bar after they move towards each other is restricted, and the position of the first fixing bar and the second fixing bar after they are attached to the body of the vertical storage tank after it is laid down is fixed, which facilitates the modular assembly operation of the workers.

[0013] The second fixing bar restricts the position of the spring piece and the connecting shell through the moving groove. This restricts the position of the rotating ball, reducing the relative friction between the connecting bar and the second fixing bar. When the tank body needs to rotate during assembly, the fastening nut can be rotated to loosen the relative position of the first and second fixing bars. Then, the spring piece loses some external force. Under the action of the spring piece, the connecting shell and the rotating ball make the rotating ball fit against the connecting bar. Rotating the tank body will cause the tank body and the connecting bar to rotate together within the first and second fixing bars, facilitating the change of the angle of the tank body and promoting modular assembly of the tank body.

[0023] like Figures 1-4As shown, a modular assembly mechanism for a pressure-resistant plate-attached F4 storage tank includes a tank body 1. Several connecting strips 2 are movably engaged with the outer wall of the tank body 1. A first fixing strip 3 and a second fixing strip 4 are movably sleeved on the outer wall of each connecting strip 2. The adjacent ends of the first fixing strip 3 and the second fixing strip 4 are rotatably connected. A hydraulic cylinder 5 is fixedly connected to the bottom end of the first fixing strip 3. A connecting rod 7 is sleeved through the other end of the first fixing strip 3. A threaded groove 8 is fixedly opened at one end of the connecting rod 7, and a fastening nut 9 is threadedly connected to the connecting rod 7 through the threaded groove 8. A limit block 12 is fixedly connected to the other end of the connecting rod 7. A connecting hole 10 is opened at the other end of the second fixing strip 4. A limit groove 11 is opened at one end of the connecting hole 10. Both the limit groove 11 and the connecting hole 10 are movable with the limit block 12. The connecting rod 7 passes through the connecting hole 10 and the limiting groove 11. The output end of the hydraulic cylinder 5 is fixedly connected to the first fixing strip 3. Both the first fixing strip 3 and the second fixing strip 4 are arc-shaped. A silicone strip 6 is fixedly connected to the inner wall of the connecting strip 2. The silicone strip 6 is tightly fitted to the outer wall of the storage tank body 1. Both the connecting strip 2 and the silicone strip 6 are C-shaped. The limiting block 12 is rectangular. The connecting hole 10 and the limiting groove 11 have the same shape and are connected. The connecting hole 10 and the limiting groove 11 are connected in a cross shape. The connecting rod 7 is T-shaped. In use, several connecting strips 2 are movably engaged with the outer wall of the storage tank body 1. The first fixing strip 3 and the second fixing strip 4 are movably sleeved on the outer wall of the connecting strip 2. One end of the first fixing strip 3 and the second fixing strip 4 are rotatably connected, so that... The connecting strip 2 is located between the tank body 1 and the first fixing strip 3 and the second fixing strip 4, so that the first fixing strip 3 and the second fixing strip 4 will not directly squeeze the tank body 1 when they rotate and tighten, reducing the possibility of damage to the paint surface of the outer wall of the tank body 1. A hydraulic cylinder 5 is fixedly connected to the bottom end of the first fixing strip 3, so that the hydraulic cylinder 5 can drive the tank body 1 to rise and fall through the first fixing strip 3, which facilitates the installation of accessories on various parts of the outer wall of the tank body 1 by the staff and facilitates the modular assembly of the tank body 1. A connecting rod 7 is sleeved through the other end of the first fixing strip 3. One end of the connecting rod 7 is fixedly provided with a threaded groove 8, and the connecting rod 7 is threadedly connected to a fastening nut 9 through the threaded groove 8, so that the first fixing strip 3 can restrict the movement direction of the connecting rod 7. This allows the fastening nut 9 to rotate along the threaded groove 8 at the upper end of the connecting rod 7. A limiting block 12 is fixedly connected to the other end of the connecting rod 7. A connecting hole 10 is provided at the other end of the second fixing strip 4, and a limiting groove 11 is provided at one end of the connecting hole 10. Both the limiting groove 11 and the connecting hole 10 are movably fitted with the limiting block 12. The connecting rod 7 passes through the connecting hole 10 and the limiting groove 11, thus fixing the connecting rod 7 and the limiting block 12 relatively. The connecting rod 7 drives the limiting block 12 to rotate 90 degrees after passing through the connecting hole 10 and then engage with the limiting groove 11. Then, rotating the fastening nut 9 restricts the position of the first fixing strip 3 and the second fixing strip 4 after they move towards each other, thus fixing the position of the first fixing strip 3 and the second fixing strip 4 after they are in contact with the tank body 1.To facilitate modular assembly by workers, both the first fixing strip 3 and the second fixing strip 4 are arc-shaped, ensuring good fit between them and the tank body 1. This design is applicable to tank bodies 1 of various sizes, enhancing practicality. A silicone strip 6 is fixedly connected to the inner wall of the connecting strip 2, and the silicone strip 6 fits tightly against the outer wall of the tank body 1. Both the connecting strip 2 and the silicone strip 6 are C-shaped, which separates the tank body 1 from the connecting strip 2. This prevents damage to the outer paint surface of the tank body 1 during assembly if it moves, and also increases the frictional resistance between the silicone strip 6 and the tank body 1, making it less likely for the tank body 1 to shift relative to the connecting strip 2. This design enhances the assembly stability of the storage tank body 1 and allows the connecting strip 2 and silicone strip 6 to be used with storage tank bodies 1 of various sizes. The rectangular limiting block 12, with identical shapes for the connecting hole 10 and the limiting groove 11, and their interconnection forming a cross shape, ensures that the limiting block 12 can only move in one direction after engaging with the limiting groove 11. Therefore, the relative positions of the first fixing strip 3 and the second fixing strip 4 are more stably fixed when the limiting block 12 and the connecting rod 7 are in contact. The T-shaped connecting rod 7, along with the limiting block 12, restricts the movement range of the fastening nut 9, preventing it from falling off and being lost.

[0024] As a preferred embodiment of this example, Figure 4As shown, the inner walls of both the second fixing strip 4 and the first fixing strip 3 are provided with several moving grooves 13. One end of the moving groove 13 is fixedly connected to a spring piece 14, and one end of the spring piece 14 is fixedly connected to a connecting shell 15. A rotating ball 16 is movably engaged in the inner cavity of the connecting shell 15. The rotating ball 16 extends to one side of the second fixing strip 4 and fits against the outer wall of the connecting strip 2. The side of the connecting shell 15 is C-shaped and is movably connected within the moving groove 13. The sides of both the second fixing strip 4 and the first fixing strip 3 are U-shaped, and the connecting strip 2 is rotatably connected between the first fixing strip 3 and the second fixing strip 4. The second fixing strip 4 and the inner wall of the first fixing strip 3 are provided with several moving grooves 13. One end of the moving groove 13 is fixedly connected to a spring piece 14, and one end of the spring piece 14 is fixedly connected to a connecting shell 15. The inner cavity of the connecting shell 15 is movably engaged with a rotating ball 16. The rotating ball 16 extends to one side of the second fixing strip 4 and fits against the outer wall of the connecting strip 2. This allows the second fixing strip 4 to restrict the position of the spring piece 14 through the moving grooves 13, thereby restricting the position of the connecting shell 15. The connecting shell 15 then restricts the position of the rotating ball 16, allowing the rotating ball 16 to reduce the distance between the connecting strip 2 and the second fixing strip 3. The relative friction between the fixing bars 4 allows the tank body 1 to rotate during assembly. By rotating the fastening nut 9, the relative positions of the first fixing bar 3 and the second fixing bar 4 can be loosened slightly. Then, the spring plate 14 loses some external force. Subsequently, under the action of the spring plate 14, the connecting shell 15 and the rotating ball 16 are brought into contact with the connecting bar 2. Rotating the tank body 1 then causes the tank body 1 and the connecting bar 2 to rotate together within the first fixing bar 3 and the second fixing bar 4, facilitating angle changes in the tank body 1 and promoting modular assembly of the tank body 1. When the relative positions of the first fixing strip 3 and the second fixing strip 4 are fixed and tightened, the connecting shell 15 will be completely squeezed into the moving groove 13, so that the relative positions of the connecting strip 2 and the second fixing strip 4 are effectively fixed. Since the side of the connecting shell 15 is C-shaped, the rotating ball 16 can rotate inside the connecting shell 15. Since the side of the second fixing strip 4 and the first fixing strip 3 are both U-shaped, the connecting strip 2 is rotatably connected to the middle of the first fixing strip 3 and the second fixing strip 4, so that the first fixing strip 3 and the second fixing strip 4 restrict the rotation position of the connecting strip 2 and prevent the tank body 1 from shifting during rotation.
