Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tank ladder structure, and particularly relates to a reinforced tank ladder structure. BACKGROUND

[0002] For large storage tanks, especially floating roof storage tanks, wind-induced buckling of the tank body is a common form of damage. To ensure that the tank wall can maintain the roundness of the upper opening and stability under the action of wind load, an anti-wind ring is usually arranged on the circumference of the tank wall. If the tank wall stability check still does not meet the requirements, a single or multiple reinforcing rings need to be arranged below the anti-wind ring to further improve the external pressure resistance of the storage tank. The spiral ladder is an indispensable auxiliary structure during the operation and maintenance of the storage tank. During construction and installation, the installation position through the opening of the anti-wind ring and the reinforcing ring must be ensured to be accurate, otherwise problems such as poor cooperation and even installation failure may occur.

[0003] In addition, according to the current manufacturing method of the ladder, one method is to segmentally assemble and weld with each layer of the tank wall plate, which has a high risk of high-altitude operation. Another method is to pre-fabricate and then integrally hoist, but there are problems such as difficulty in controlling the spiral angle of the inner and guard rails and low production efficiency. CONTENT OF THE INVENTION

[0004] Therefore, the application aims to provide a reinforced tank ladder structure to solve the problems of complex tank ladder structure, tedious installation process, and high risk of high-altitude operation.

[0005] To achieve the above-mentioned purpose, the technical scheme of the application is as follows:

[0006] The application provides a reinforced tank ladder structure, which comprises:

[0007] A fixing member is arranged on the outer wall of the tank body in a spiral shape.

[0008] A pedal is fixedly connected to the fixing member through a flow guide connecting member, and a guardrail is arranged on the end side wall of the pedal away from the tank body, and a walking channel is formed between the guardrail and the tank body.

[0009] A plurality of inclined braces are arranged on the outer wall of the tank body in a spaced manner and connected to the guardrail.

[0010] Further, the number of fixing members is multiple, and the multiple fixing members are arranged on the outer wall of the tank body in a spiral shape.

[0011] Further, the fixing member comprises a supporting part and a fixing part connected to the supporting part.

[0012] The support is fixedly mounted on the outer wall of the tank, and the fixed part has a fixing hole for installing the flow guide connector.

[0013] Furthermore, the support is arranged at a horizontal angle and has an outward slope relative to the outer wall of the tank.

[0014] Furthermore, the end of the pedal near the tank body extends downward to form a connecting part, and the vertical plate of the connecting part has an installation hole corresponding to the fixing hole. The connecting part and the fixing part are fixedly connected by a flow guide connector.

[0015] Furthermore, the connecting part has an L-shaped structure.

[0016] Furthermore, the flow guiding connector includes a flow guiding bolt and a nut that mates with the flow guiding bolt;

[0017] The guide bolt includes an integrally formed bent portion and a guide portion. One end of the bent portion is provided with an external thread. The bent portion passes through the mounting hole and the fixing hole and is assembled and connected with the nut.

[0018] Furthermore, the included angle between the bent portion and the guide portion is 120° to 135°;

[0019] The angle between the outlet end of the guide section and the tank wall is 45-60°.

[0020] Furthermore, the interior of the flow guide connector is hollow.

[0021] Furthermore, the flow guide connector is made of bent round steel.

[0022] Furthermore, the spiral ascent angle at the top and bottom of the storage tank is smaller than the spiral ascent angle at the middle of the storage tank.

[0023] Furthermore, the spiral ascent angle at the top and bottom of the storage tank is 20° to 25°, for example, 20°; the spiral ascent angle in the middle of the storage tank is 25° to 35°, for example, 35°.

[0024] Compared with the prior art, the reinforced tank ladder structure described in this application has the following advantages:

[0025] (1) The reinforced tank ladder structure described in this application has high manufacturing precision and efficiency. After the entire ladder is hoisted, it can be installed with the tank wall through the flow guide connector, which greatly reduces the risk of high-altitude operation and speeds up the construction progress.

[0026] (2) The reinforced storage tank plate structure described in this application can improve the wind resistance of the upper part of the storage tank by setting several fixing parts on the outer wall of the tank, and can also share the circumferential stress generated by the material load on the tank wall, effectively reducing the thickness of the storage tank wall and reducing the cost.

[0027] (3) The guide bolts in the reinforced tank plate structure described in this application can avoid the obstruction of fire sprinkler water by the fixing parts. The fire water accumulated in the guide bolt groove can be guided to the tank wall through the hollow part of the guide connector and sprayed on the tank wall at a specific angle (such as a 60° angle) so that the fire water is evenly distributed and achieves a better cooling effect, further ensuring the safety of the tank.

[0036] Please see Figure 1 and Figure 2 As shown, this embodiment provides a reinforced storage tank tray ladder structure, including:

[0037] Fastener 2 is spirally distributed on the outer wall of the tank body of storage tank 1;

[0038] The pedal 3 is fixedly connected to the fixing part 2 through the flow guide connector, and a guardrail 5 is provided on the side wall of the pedal 3 away from the tank body, forming a walking channel between the guardrail 5 and the tank body.

[0039] Diagonal braces 6, there are multiple diagonal braces 6, which are arranged at intervals on the outer wall of the tank and connected to the guardrail 5.

[0040] Specifically, in this embodiment, the spiral ladder structure combines the reinforcing effects of a wind-resistant ring and a reinforcing ring, increasing the overall rigidity of the tank wall. It is also easy to manufacture, allowing for precise positioning of the ladder treads 3 and rapid layout of the guardrail 5, thus improving manufacturing efficiency. Furthermore, since the spiral ladder and the fixing component 2 are integrated after installation, there is no need to address the misalignment issue between the ladder and the fixing component 2, greatly simplifying the installation process. In addition, the spiral ladder also has a fire sprinkler water diversion function, preventing the fixing component 2 from blocking the fire sprinkler water and ensuring even distribution of the fire sprinkler water along the tank wall, improving the cooling effect.

[0041] The storage tank 1 with a spiral ladder structure described in this embodiment has a spiral ladder guardrail 5 with high manufacturing precision. After the spiral ladder is hoisted as a whole, it can be installed with the tank wall through the flow guide connector, which reduces the risk of high-altitude operations. The spiral ladder has the reinforcement effect of both wind-resistant ring and reinforcing ring, which can increase the overall rigidity of the tank wall.

[0042] In some implementations, such as Figure 2As shown, the fastener 2 includes a support part 21 and a fixing part 22 connected to the support part 21. A reinforcing rib is also provided at the connection between the support part 21 and the fixing part 22. The reinforcing rib is not shown in the figure.

[0043] The support part 21 is fixedly installed on the outer wall of the tank, and the fixing part 22 is provided with fixing holes for installing the flow guide connector.

[0044] Specifically, in this embodiment, the fixing member 2 has an L-shaped structure. The support part 21 and the outer wall of the tank are connected by a fully penetrated butt weld. The upper surface of the support part 21 is connected by a continuous full fillet weld, and the lower surface of the support part 21 is connected by an intermittent welding technique. The fixing member 2 is firmly fixed to the outer wall of the tank. The fixing member 2 provides a fixed platform for the rapid installation of the ladder and guardrail 5. The rapid installation of the ladder and the fixing member 2 is achieved by using the flow guide connector, which effectively reduces the risk of working at height and greatly ensures the personal safety of workers at height.

[0045] In some embodiments, the support portion 21 is arranged at a horizontal angle, and the support portion 21 is formed with an outward slope relative to the outer wall of the tank.

[0046] Specifically, in this embodiment, the outer side of the support 21 is slightly lower than the inner side, and can be set to a 1% slope to prevent rainwater or fire sprinkler water from remaining on the tank wall and forming water stains or corrosion.

[0047] In some implementations, such as Figure 3 As shown, the end of the pedal 3 near the tank body extends downward to a connecting part 31. The connecting part 31 has an L-shaped structure. The vertical plate of the connecting part 31 has a mounting hole 32 corresponding to the fixing hole. The connecting part 31 and the fixing part 22 are fixedly connected by a flow guide connector.

[0048] Specifically, in this embodiment, a connecting portion 31 extends downward from the end of the pedal 3 near the fixing member 2. The connecting portion 31 connects with the fixing member 2, and the two can be quickly fixed together by a guide connector. It should be noted that, to meet actual installation and application requirements, this embodiment only uses one corresponding mounting hole 32 and fixing hole as an example. Those skilled in the art can set up a multi-hole installation method according to actual needs during actual installation to improve stability and support.

[0049] In this embodiment, the inner side of the guardrail 5 is welded to the side of the pedal 3 away from the tank body. The upper surface of the pedal 3 is welded with a continuous full fillet weld, and the lower surface is welded with an intermittent weld. Along the plane projection of the spiral line, the guardrail 5 is provided with a diagonal brace 6 welded to the outer wall of the storage tank 1 at 30° intervals.

[0050] Once the fastener 2 is completed, the positions of all the pedals 3 connected to the fastener 2 through the mounting holes 32 and the guide connectors are determined. The line connecting the side of each pedal 3 away from the fastener 2 is the spiral line on the inner side of the guardrail 5. Therefore, the mounting holes 32 opened on the pedals 3 can be regarded as positioning holes for the guardrail 5, which greatly improves the manufacturing accuracy and efficiency of the guardrail 5.

[0051] In some implementations, such as Figure 2 As shown, the flow guide connector includes a flow guide bolt 4 and a nut that mates with the flow guide bolt 4. The flow guide bolt 4 is hollow inside.

[0052] The guide bolt 4 includes an integrally formed bent portion 41 and a guide portion 42. The included angle between the bent portion 41 and the guide portion 42 is 120°. One end of the bent portion 41 is provided with an external thread. The bent portion 41 passes through the mounting hole and the fixing hole and is assembled and connected with the nut.

[0053] Specifically, in this embodiment, the guide bolt 4 can prevent the fixing part 2 from blocking the fire sprinkler water. The fire water accumulated in the groove of the fixing part 2 can be guided to the tank wall through the hollow part of the guide bolt 4 and sprayed at a 60° angle to the tank wall, so that the fire water is evenly distributed, achieving a better cooling effect and further ensuring the safety of the storage tank 1.

[0054] In some embodiments, the spiral ascent angle at the top and bottom of the storage tank 1 is smaller than the spiral ascent angle at the middle of the storage tank 1.

[0055] Specifically, in this embodiment, the spiral rise angle at the top and bottom of the tank wall is set to 20°, and the spiral rise angle in the middle of the tank wall is set to 35°. This makes the spiral support structure formed by the fixing member 2 have better wind resistance in the upper part of the storage tank 1 and more of the circumferential stress generated by the material load on the wall of the storage tank 1 in the lower part of the storage tank 1.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
