Description

Technical Field

[0001] The present application belongs to the technical field of storage tank spiral ladders, and in particular, relates to a reinforced storage tank spiral ladder structure. Background Art

[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 still maintain the roundness and stability of the upper opening under wind load, a windproof ring is usually set on its circumference. If the tank wall stability check is still not satisfied at this time, it is necessary to set a single or multiple reinforcement rings under the windproof ring to further improve the tank's ability to resist external pressure. The spiral ladder is an indispensable auxiliary structure for tank operation and maintenance. During construction and installation, it is necessary to ensure that the installation position through the windproof ring and the reinforcement ring opening is accurate, otherwise there will be problems such as loose fit or even inability to install.

[0003] In addition, there are two methods for making spiral ladders: one is to weld the tank wall panels in sections at each level, which has a higher risk of high-altitude operations; the other is to prefabricate and then hoist the entire ladder, but there are problems such as the spiral angles of the inner and guardrails are difficult to control and the production efficiency is low. Summary of the invention

[0004] In view of this, the present application aims to propose a reinforced tank spiral ladder structure to solve the problems of complex tank spiral ladder structure and cumbersome installation process, which leads to difficulty in quick installation and high risk of high-altitude operations.

[0005] To achieve the above purpose, the technical solution of this application is implemented as follows:

[0006] The present application provides a reinforced tank ladder structure, comprising:

[0007] A fixing part, wherein the fixing part is spirally distributed on the outer wall of the storage tank body;

[0008] A pedal, wherein the pedal is fixedly connected to the fixing member via a flow guide connecting member, and a guardrail is provided on a side wall of an end of the pedal away from the tank body, and a walking passage is formed between the guardrail and the tank body;

[0009] There are multiple diagonal braces, which are arranged at intervals on the outer wall of the tank body and connected to the guardrail.

[0010] Furthermore, there are multiple fixing members, and the multiple fixing members are distributed on the outer wall of the storage tank body in a spiral shape.

[0011] Further, the fixing member includes a supporting portion and a fixing portion connected to the supporting portion;

[0014] Furthermore, a connecting portion is extended downwardly from one end of the pedal close to the tank body, a mounting hole corresponding to the fixing hole is formed on a vertical plate of the connecting portion, and the connecting portion is fixedly connected to the fixing portion via a flow guide connector.

[0015] Furthermore, the connecting portion is an L-shaped structure.

[0016] Further, the flow guide connecting piece includes a flow guide bolt and a nut matched with the flow guide bolt;

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

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

[0036] See also Figure 1 and Figure 2 As shown, this embodiment provides a reinforced tank ladder structure, including:

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

[0038] A pedal 3, the pedal 3 is fixedly connected to the fixing member 2 through a flow guide connector, and a guardrail 5 is provided on the side wall of one end of the pedal 3 away from the tank body, and a walking passage is formed between the guardrail 5 and the tank body;

[0039] The diagonal braces 6 are multiple in number, and the multiple diagonal braces 6 are arranged on the outer wall of the tank body at intervals and connected to the guardrail 5 .

[0040] Specifically, in this embodiment, the spiral ladder structure has the reinforcing effect of both the windproof ring and the reinforcement ring, which can increase the overall rigidity of the tank wall. At the same time, it is easy to manufacture, and the spiral ladder pedal 3 can be accurately positioned, and the guardrail 5 can be quickly laid out, thereby improving the manufacturing efficiency. In addition, since the spiral ladder is an integrated structure with the fixing 2 after being installed in place, there is no need to deal with the intersection problem of the spiral ladder and the fixing 2, which greatly simplifies the installation procedure. In addition, the spiral ladder also has a fire sprinkler fire sprinkler water diversion function, which can avoid the fire sprinkler water being blocked by the fixing 2, and make the fire sprinkler water evenly distributed along the tank wall, improving the cooling effect.

[0041] The present embodiment describes a spiral ladder structure for a storage tank 1, wherein the spiral ladder guardrail 5 is manufactured with high precision. After the spiral ladder is hoisted as a whole, it can be installed on the tank wall through a guide connector, and the risk of high-altitude operations is low. The spiral ladder has the reinforcement effects of both a wind-resistant ring and a reinforcement ring, which can increase the overall stiffness of the tank wall.

[0042] In some embodiments, Figure 2As shown, the fixing member 2 includes a supporting portion 21 and a fixing portion 22 connected to the supporting portion 21. A reinforcing rib is also provided at the connection between the supporting portion 21 and the fixing portion 22, which is not shown in the drawings;

[0043] The supporting portion 21 is fixedly arranged on the outer wall of the tank body, and a fixing hole for installing the flow guide connector is opened on the fixing portion 22 .

[0044] Specifically, in this embodiment, the fixing part 2 is of an L-shaped structure, the support part 21 and the outer wall of the tank body are connected by a fully penetrated butt weld, the upper surface of the support part 21 is connected by a continuous full-angle weld, and the lower surface of the support part 21 is connected by an intermittent welding technology. The fixing part 2 is firmly fixed to the outer wall of the tank body, and the fixing part 2 provides a fixed platform for quickly installing the spiral ladder and the guardrail 5. The guide connector is used to realize the rapid installation of the spiral ladder and the fixing part 2, which effectively reduces the risk of high-altitude operations and greatly ensures the personal safety of high-altitude operators.

[0045] In some embodiments, the support portion 21 is arranged to be transversely inclined, and the support portion 21 is formed with a slope that is inclined outward relative to the outer wall of the tank body.

[0046] Specifically, in this embodiment, the outer side of the support portion 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 to form water stains or corrosion.

[0047] In some embodiments, Figure 3 As shown, a connecting portion 31 extends downward from one end of the pedal 3 close to the tank body. The connecting portion 31 is an L-shaped structure. A mounting hole 32 corresponding to the fixing hole is opened on the vertical plate of the connecting portion 31. The connecting portion 31 is fixedly connected to the fixing portion 22 through a guide connector.

[0048] Specifically, in this embodiment, a connecting portion 31 is extended downward from one end of the pedal 3 close to the fixing member 2, and the connecting portion 31 is connected to the fixing member 2, and then the two can be quickly fixed through the guide connector. It should be noted that in the case of meeting actual installation requirements and application requirements, this embodiment only takes the setting of a corresponding installation hole 32 and a fixing hole as an example. Those skilled in the art can set a multi-hole installation form according to actual needs during specific installation to improve stability and support effects.

[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, and the upper surface of the pedal 3 is welded with continuous full fillet welding, and the lower surface is welded with intermittent welding. The guardrail 5 is projected along the plane of the spiral line, and a diagonal brace 6 is provided at every 30° interval to be welded to the outer wall of the storage tank 1.

[0050] When the fixing member 2 is manufactured, the positions of all pedals 3 connected to the fixing member 2 through the mounting holes 32 and the flow guide connector are determined, and the line connecting the pedals 3 away from the fixing member 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 manufacturing the guardrail 5, which greatly improves the manufacturing accuracy and efficiency of the guardrail 5.

[0051] In some embodiments, Figure 2 As shown, the flow guide connecting piece includes a flow guide bolt 4 and a nut matched with the flow guide bolt 4, and the interior of the flow guide bolt 4 is hollow;

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

[0053] Specifically, in this embodiment, the setting of the guide bolt 4 can avoid the blocking of the fire sprinkler water by the fixing member 2. The fire water accumulated in the groove of the fixing member 2 can be drained to the tank wall through the hollow part of the guide bolt 4 and sprayed on the tank wall at an angle of 60°, 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 rise angles at the top and bottom of the storage tank 1 are smaller than the spiral rise angle at the middle of the storage tank 1 .

[0055] Specifically, in this embodiment, the spiral rising angles at the top and bottom of the tank wall are set to 20°, and the spiral rising angle in the middle of the tank wall is set to 35°, so that the spiral support structure formed by the fixing member 2 has better wind resistance at the upper part of the storage tank 1, and more of the circumferential stress caused by the material load on the wall plate of the storage tank 1 is shared at the lower part of the storage tank 1.
