Description

Technical Field

[0001] This utility model relates to the field of storage tank installation technology, and in particular to a wind-resistant platform device for inverted storage tanks. Background Technology

[0002] Common installation methods for metal storage tanks mainly include the direct installation method and the inverted installation method. The direct installation method uses the bottom of the tank as the starting plane and installs the tank wall panels one section at a time from the bottom. The inverted installation method uses the bottom of the tank as the reference, first installs the top ring wall panel and the top of the tank, and then starts from the top, using the hydraulic lifting mechanism 1 to lift the tank wall and the top of the tank, and then assembles, welds and lifts the tank wall one ring at a time downwards.

[0003] When using the inverted installation method for storage tanks in coastal cities, the high wind speeds, sudden gusts, and long durations of typhoons pose significant challenges. The hydraulic lifting mechanism 1 must simultaneously resist both vertical lifting forces and horizontal wind loads. Traditional anti-tipping measures for hydraulic lifting mechanisms, such as installing diagonal braces 11 on the side of the mechanism to prevent tipping, are insufficient to withstand the wind loads generated by typhoons, leading to tank instability. Furthermore, during the panel assembly process, the tank is semi-enclosed, and uneven wind pressure distribution can easily cause localized instability, making it difficult to complete the installation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wind-resistant platform device for inverted storage tanks, which is mainly used for the installation of storage tanks in coastal areas to adapt to typhoon weather, reduce the risk of overturning of hydraulic lifting mechanisms, avoid personnel injury, and achieve the purpose of reducing safety risks and construction costs.

[0005] This utility model discloses a wind-resistant platform device for an inverted storage tank, including a tank bottom plate and a hydraulic lifting mechanism for lifting the tank wall. The hydraulic lifting mechanism is evenly distributed around the center of the tank bottom plate along the circumference of the tank bottom plate. The tank bottom plate is provided with a lower steel plate, and a column located at the center of the tank bottom plate is provided on the lower steel plate. An upper steel plate is provided on the column. The height of the upper steel plate is consistent with the top height of the hydraulic lifting mechanism. Each hydraulic lifting mechanism is provided with a horizontal tie rod connected to the upper steel plate at its top.

[0006] Furthermore, a stiffening plate that connects to the column is provided below the upper steel plate.

[0007] Furthermore, a connecting plate for movement is provided between two adjacent horizontal tie rods.

[0008] As a preferred embodiment, the connecting plate is circularly laid above the horizontal tie rod and connected to each horizontal tie rod.

[0009] Furthermore, the column is equipped with a ladder that runs along the height of the column.

[0010] As a preferred embodiment, the ladder is spirally installed on the column along the height direction of the column.

[0011] Furthermore, each of the horizontal tie rods has a diagonal brace connected to the bottom of the column at the end closest to the hydraulic lifting mechanism.

[0012] Furthermore, the hydraulic lifting mechanism is arranged in a ring around the bottom plate of the tank body at 22.5° intervals, with the column as the center.

[0013] The beneficial effects of this utility model are as follows: By using this inverted tank wind-resistant platform device, and by setting up columns and horizontal tie rods connected to the columns and hydraulic lifting mechanism, the columns and hydraulic lifting mechanism are pulled against each other, which can meet the anti-tipping arrangement in typhoon and strong wind weather, effectively prevent the risk of instability of the storage tank caused by typhoon and strong wind weather, reduce the risk of overturning of the hydraulic lifting mechanism, and avoid personnel injury; and by reducing the number of welding points between the tank and the tank wall, the impact of repeated welding and cutting on the quality of the tank wall is reduced, thus improving the construction quality and safety.

Detailed Implementation

[0017] The present invention will be further described below.

[0018] This utility model provides a wind-resistant platform device for inverted storage tanks, mainly used for storage tank installation in coastal areas. It includes a tank bottom plate 2 and a hydraulic lifting mechanism 1 for lifting the tank wall 21. The hydraulic lifting mechanism 1 is evenly distributed around the center of the tank bottom plate 2 along the circumference of the tank bottom plate 2. A lower steel plate 31 is provided on the tank bottom plate 2. A column 3 located at the center of the tank bottom plate 2 is provided on the lower steel plate 31. An upper steel plate 32 is provided on the column 3. The height of the upper steel plate 32 is the same as the top height of the hydraulic lifting mechanism 1. Each hydraulic lifting mechanism 1 has a horizontal tie rod 33 connected to the upper steel plate 32 at its top.

[0019] like Figure 1 , Figure 2 As shown, the inverted tank wind-resistant platform device includes a tank bottom plate 2, which serves as the foundation of the entire device. Multiple hydraulic lifting mechanisms 1 are evenly distributed around the circumference of the tank bottom plate 2, used to lift and install the tank wall 21. A lower steel plate 31 is provided on the tank bottom plate 2, welded to it to provide a stable support surface. A vertical column 3, located at the center of the tank bottom plate 2, is provided on the lower steel plate 31, serving as the core support structure of the inverted tank wind-resistant platform device. An upper steel plate 32 is provided at the top of the column 3, its height matching the top height of the hydraulic lifting mechanism 1, providing an installation point for the horizontal tie rod 33 and ensuring its levelness. One end of the horizontal tie rod 33 is connected to the upper steel plate 32, and the other end is connected to the top of the hydraulic lifting mechanism 1. The components are connected to form a stable support structure. Specifically, a horizontal tie rod 33 is welded to the top of the hydraulic lifting mechanism 1. The other end of the horizontal tie rod 33 is set on the column 3, forming a tie rod to ensure the connection stability between the column 3 and the hydraulic lifting mechanism 1. That is, the horizontal tie rod 33 achieves the contact between the column 3 and the hydraulic lifting mechanism 1, effectively dispersing wind force and improving the wind resistance of the device. The horizontal tie rod 33 is welded to the hydraulic lifting mechanism 1 and the column 3. All connection points are fully welded to ensure the firmness and stability of the connection. This improves the overall stability of the device. Moreover, the inverted storage tank wind-resistant platform device will not be in contact with the tank wall 21, which can avoid repeated welding and cutting of the tank wall 21, reduce the impact of welding points on the quality of the tank wall 21, and improve construction quality and safety. It is suitable for the construction of inverted storage tanks in coastal areas, ensuring construction efficiency, construction quality and construction safety. The upper steel plate 32 and lower steel plate 31 used above can be 20mm thick steel plates, and the column 3 can be made of DN300 welded steel pipe, which has low manufacturing cost. The hydraulic lifting mechanism used above can be an existing hydraulic lifting machine.

[0020] To ensure the connection strength between the upper steel plate 32 and the column 3, such as Figure 1 As shown, a stiffening plate 34 connected to the column 3 is provided below the upper steel plate 32. The stiffening plate 34 enhances the connection strength between the upper steel plate 32 and the column 3, and improves the load-bearing capacity and stability of the entire device, so as to ensure that the upper steel plate 32 does not deform after the multiple horizontal tie rods 33 are set on the upper steel plate 32 and connected to the hydraulic lifting mechanism 1. When the wind force is large, the stiffening plate 34 can effectively disperse the stress and prevent the upper steel plate 32 from deforming or being damaged.

[0021] To facilitate construction operations and inspections by staff, such as Figure 2As shown, a connecting plate 25 for walking is provided between two adjacent horizontal tie rods 33. The connecting plate 25 provides a passage for workers to walk, meeting the needs of personnel to operate and inspect the hydraulic system. Operators do not need to weld strips to the shell of the tank wall 21 so that they can inspect the tank wall 21 which has been lifted by the hydraulic lifting mechanism 1 for welding. This ensures the safety of operators and avoids repeated welding and cutting of the tank wall 21, which would cause quality risks to the tank wall 21. It ensures the safety of personnel going up and down and the safety and quality risks caused by special windy weather, while also ensuring economic benefits. The connecting plate 25 can be made of steel planks, and the steel planks are fixed to the horizontal tie rods 33 with iron wire.

[0022] As a preferred method, to avoid bending and deformation of the horizontal tie rod 33 due to uneven force at both ends, the connecting plate 25 is laid out in a circular shape above the horizontal tie rod 33 and connected to each horizontal tie rod 33. That is, the circular connecting plate 25 is fully laid above all the horizontal tie rods 33. Operators can climb up the column 3 to the connecting plate 25 to inspect and repair the hydraulic lifting mechanism 1 and the welding of the tank wall 21. Moreover, the circular connecting plate 25 is connected to each horizontal tie rod 33, which ensures the stability and safety of the connection and prevents workers from falling or other safety accidents during the process.

[0023] To facilitate the operator's movement to the connecting plate 25 above column 3, such as Figure 1 As shown, the column 3 is provided with a ladder 36 arranged along the height direction of the column 3; the ladder 36 can be welded to the circumference of the column 3 so that operators can climb up from all directions; as a preferred method, in order to save installation space of the ladder 36, the ladder 36 is spirally arranged on the column 3 along the height direction of the column 3, which improves work efficiency and safety.

[0024] To ensure the connection strength between the horizontal tie rod 33 and the column 3, such as Figure 1 As shown, each of the horizontal tie rods 33 is provided with a diagonal brace 37 connected to the bottom of the column 3 at the lower end of the end near the hydraulic lifting mechanism 1; the diagonal brace 37 enhances the connection strength between the horizontal tie rod 33 and the column 3, and improves the stability and load-bearing capacity of the entire device; when the wind is strong, the diagonal brace 37 can effectively disperse the force on the horizontal tie rod 33 and prevent it from deforming or being damaged.

[0025] like Figure 2 As shown, to ensure the synchronous lifting of the tank wall 21 by the hydraulic lifting mechanism 1, actual on-site operation tests were conducted, such as... Figure 2As shown, the hydraulic lifting mechanism 1 is arranged in a ring around the bottom plate 2 of the tank body with the column 3 as the center and at intervals of 22.5°. By arranging the hydraulic lifting mechanism 1 in a ring around the bottom plate 2 of the tank body, the stability of the tank wall 21 during the lifting process is effectively improved. At the same time, the evenly distributed hydraulic lifting mechanism 1 can better resist the action of external loads such as wind force, ensuring the stability of the tank during the installation process.
