Description

Technical Field

[0001] This application relates to the field of storage tank maintenance, and in particular to a steel platform for storage tanks. Background Technology

[0002] Steel storage tanks are sealed steel containers used to store liquids or gases. Steel storage tank projects are essential and crucial infrastructure in industries such as petroleum, chemical, grain and oil, food, fire protection, transportation, metallurgy, and national defense. During daily use, workers need to periodically climb to the top of the tank to perform maintenance and repairs.

[0003] Currently, the common practice is to install steel platforms with stairs on the storage tanks, allowing workers to ascend to the top for maintenance and repair. However, existing steel platforms are typically assembled by welding together multiple steel components, requiring extensive welding work during assembly. Welding generates sparks and high temperatures, posing significant safety hazards when dealing with flammable and explosive storage tanks like oil tanks. Utility Model Content

[0004] To improve the safety of installing steel platforms on flammable and explosive storage tanks such as oil tanks, this application provides a storage tank steel platform.

[0005] The steel platform for a storage tank provided in this application adopts the following technical solution:

[0006] A steel platform for a storage tank includes a positioning ring, a staircase, a platform, and a bracing mechanism. The positioning ring is circumferentially positioned on the top of the storage tank. The staircase is erected on the storage tank and fastened to the positioning ring. Multiple platforms are circumferentially positioned on the top of the storage tank. The side of each platform closest to the storage tank is fastened to the positioning ring. The bracing mechanism is positioned on the platform and used to support the platform.

[0007] By adopting the above technical solution, workers can erect a staircase on the storage tank and secure it to the positioning ring. Then, multiple platforms are arranged and installed along the top circumference of the storage tank, securing them to the positioning ring. The platforms are then supported by a diagonal bracing mechanism, thus completing the installation of the steel platform on the storage tank. This reduces the welding operations required during installation and effectively improves the safety of installing steel platforms on flammable and explosive storage tanks such as oil tanks.

[0008] Optionally, the platform includes a steel frame, a grating, railings, and a locking assembly. The steel frame is fastened to a positioning ring, the grating is laid on the steel frame, the railings are inserted into the steel frame, and the locking assembly is mounted on the steel frame and used to position the railings.

[0009] By adopting the above technical solution, the workers fasten the steel frame to the positioning ring, then lay the grating plate on the steel frame, insert the railings into the steel frame, and then use the locking components to position the railings on the steel frame, thus completing the assembly of the platform conveniently and quickly.

[0010] Optionally, the locking assembly includes a locking bolt and a locking nut, the locking bolt passing through the steel frame and mounted on the railing, and the locking nut being threaded onto the locking bolt.

[0011] By adopting the above technical solution, workers pass the locking bolt through the steel frame and through the railing, and then tighten the locking nut onto the locking bolt to position the railing on the steel frame.

[0012] Optionally, the diagonal bracing mechanism includes a diagonal brace and a support seat. The diagonal brace is hinged to the steel frame, and the support seat is disposed on the outer wall of the storage tank and is used to support the diagonal brace.

[0013] By adopting the above technical solution, the workers rotate the diagonal brace so that it comes into contact with the support seat. The support seat supports the diagonal brace, and the diagonal brace can then provide stable support for the steel frame.

[0014] Optionally, the diagonal brace includes a steel pipe, a screw rod, and an adjusting disc. The steel pipe is hinged to the steel frame, the screw rod is slidably inserted into the steel pipe and abuts against the support seat, and the adjusting disc is threaded onto the screw rod.

[0015] By adopting the above technical solution, the staff can rotate the adjustment plate to adjust its position on the screw. When the screw abuts against the receiving seat, the screw drives the adjustment plate to abut against the steel pipe, thereby adjusting the length of the screw extending out of the steel pipe and thus adjusting the length of the diagonal brace, improving the applicability of the diagonal brace to different support length requirements.

[0016] Optionally, a kick plate is provided on the steel frame, which closes off the lower part of the railing near the steel frame.

[0017] By adopting the above technical solution, the kick plate encloses the lower part of the railing near the steel frame, reducing the possibility of items falling from the lower part of the railing near the steel frame.

[0018] Optionally, a reinforcing bolt is slidably passed through the positioning ring, the reinforcing bolt passes through the steel frame, and a reinforcing nut is threaded onto the reinforcing bolt.

[0019] By adopting the above technical solution, the workers pass the reinforcing bolt through the positioning ring and through the steel frame, and then tighten the reinforcing nut onto the reinforcing bolt, which locks the steel frame onto the positioning ring and improves the stability of the steel frame on the positioning ring.

[0020] Optionally, the positioning ring has a slot for the reinforcing bolt to pass through, and the width of the slot is greater than the diameter of the reinforcing bolt.

[0021] By adopting the above technical solution, after the reinforcing bolt passes through the strip hole and then through the steel frame, the staff can still adjust the position of the steel frame. During the adjustment process, the reinforcing bolt slides in the strip hole, reducing the requirement for the accuracy of the steel frame installation position.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Reduces the welding operations required during installation, effectively improving the safety of installing steel platforms on flammable and explosive storage tanks such as oil tanks;

[0024] 2. Adjust the length of the diagonal brace to improve its applicability to different support length requirements. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a steel platform for storage tanks.

[0031] Reference Figure 1 , Figure 2 The steel platform of the storage tank includes a positioning ring 1, a staircase 2, a platform 3, and a diagonal bracing mechanism 4. The positioning ring 1 is circumferentially installed on the outer periphery of the top of the storage tank. One end of the staircase 2 is placed on the storage tank, and the other end of the staircase 2 is installed on the ground. The end of the staircase 2 closest to the storage tank protrudes downward and is fastened to the inner side of the positioning ring 1, thereby improving the stability of the staircase 2 on the storage tank.

[0032] Reference Figure 2 , Figure 3 Platform 3 is installed on the top of the storage tank along the outer edge of the tank. Platform 3 includes a steel frame 31, a grating plate 32, a railing 33, and a locking assembly 34. The steel frame 31 is made of multiple steel pieces spliced ​​and welded horizontally and vertically in the factory. The side of the steel frame 31 near the storage tank has the same curvature as the outer periphery of the storage tank. The end of the steel frame 31 near the storage tank protrudes downward and is fastened to the inner side of the positioning ring 1. A reinforcing bolt 6 is installed on the positioning ring 1. A horizontal slot 11 is opened on the positioning ring 1. The width of the slot 11 is greater than the diameter of the reinforcing bolt 6. The reinforcing bolt 6 passes through the slot 11 and is installed on the downward protruding part of the steel frame 31. A reinforcing nut 7 is threaded on the end of the reinforcing bolt 6 that passes through the slot 11.

[0033] Workers move the steel frame 31 so that the downward protruding part of the end of the steel frame 31 closest to the storage tank is fastened to the inside of the positioning ring 1. Then, the reinforcing bolt 6 is passed through the slot 11 and through the downward protruding part of the steel frame 31. The reinforcing nut 7 is then tightened onto the reinforcing bolt 6, which positions the steel frame 31 onto the positioning ring 1, improving the stability of the connection between the steel frame 31 and the positioning ring 1. After the workers pass the reinforcing bolt 6 through the slot 11 and the steel frame 31, they can also move the steel frame 31 to adjust its position. During the adjustment process, the reinforcing bolt 6 slides in the slot 11, reducing the accuracy requirements for the installation of the steel frame 31 and making it easier for workers to install the steel frame 31.

[0034] Reference Figure 2 , Figure 3 The grating 32 is laid on the steel frame 31, and the steel frame 31 has reserved holes. The railing 33 is inserted into the holes. A kick plate 5 is installed on the side of the steel frame 31 away from the storage tank. The kick plate 5 closes the gap of the railing near the lower part of the steel frame 31, reducing the possibility of items on the grating 32 falling from the railing 33 near the lower part of the steel frame 31, and improving the safety under the storage tank.

[0035] Reference Figure 2 , Figure 3 The locking assembly 34 is mounted on the steel frame 31. The locking assembly 34 is used to position the railing 33 on the steel frame 31. The locking assembly 34 includes a locking bolt and a locking nut. The locking bolt passes through the steel frame 31 and through the railing 33. The locking nut is threaded onto the locking bolt.

[0036] Workers install the steel frame 31 onto the positioning ring 1, lay the grating plate 32 onto the steel frame 31, then install the railing 33 onto the steel frame 31, pass the locking bolt through the steel frame 31 and through the railing 33, and then tighten the locking nut onto the locking bolt. This positions the railing 33 on the steel frame 31, making the assembly of the dinner platform 3 convenient and quick.

[0037] Reference Figure 1 , Figure 2The diagonal bracing mechanism 4 is installed on the steel frame 31 and is used to support the steel frame 31. The diagonal bracing mechanism 4 includes a diagonal bracing rod 41 and a support seat 42. The support seat 42 is bolted to the outer wall of the storage tank. The support seat 42 has a slot for inserting the diagonal bracing rod 41. The diagonal bracing rod 41 is hinged to the steel frame 31. The diagonal bracing rod 41 includes a steel pipe 411, a screw rod 412 and an adjusting plate 413. The steel pipe 411 is hinged to the bottom of the steel frame 31 away from the storage tank. The screw rod 412 is slidably inserted into the end of the steel pipe 411 away from the steel frame 31. The adjusting plate 413 is threaded onto the screw rod 412.

[0038] After positioning the steel frame 31 on the positioning ring 1, the worker rotates the steel pipe 411 so that the screw 412 aligns with the receiving seat 42. Then, the screw 412 is pulled out of the steel pipe 411 and inserted into the receiving seat 42. Next, the worker rotates the adjusting plate 413 so that it abuts against the steel pipe 411. Through the abutment between the adjusting plate 413 and the steel pipe 411, the screw 412 supports the steel pipe 411, which in turn supports the steel frame 31. The support enhances the stability of the steel frame 31 on the storage tank. Furthermore, the operator can adjust the position of the adjustment plate 413 on the screw 412 by rotating the adjustment plate 413, thereby adjusting the length of the screw 412 extending out of the steel pipe 411. This allows the diagonal brace 41 to be adjusted to different lengths. When different tilt angles require support, the screw 412 can be pressed against the support seat 42, improving the applicability of the diagonal brace 41 to different support length requirements.

[0039] The implementation principle of a steel platform for a storage tank according to an embodiment of this application is as follows: Workers erect a staircase 2 on the storage tank, and then fasten the staircase 2 to the positioning ring 1. Then, multiple platforms 3 are arranged circumferentially along the top of the storage tank, so that the multiple platforms 3 surround the outer perimeter of the top of the storage tank, and the steel frame 31 is fastened to the positioning ring 1. The steel frame 31 and the positioning ring 1 are locked by reinforcing bolts 6 and reinforcing nuts 7. Then, the grating plate 32 is laid on the steel frame 31, and the railing 33 is positioned and installed on the steel frame 31 by locking bolts and locking nuts. Finally, the diagonal brace 41 is abutted against the support seat 42 to support the steel frame 31. The installation of multiple platforms 3 is completed, and the steel platform is installed on the storage tank. The entire installation process reduces the need for welding operations and effectively improves the safety when installing steel platforms on flammable and explosive storage tanks such as oil tanks.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
