Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of module hoisting, and more particularly to a large chemical device module hoisting lug node. BACKGROUND

[0002] With the continuous development of society and the acceleration of industrialization process, the construction mode of traditional chemical devices is facing multiple challenges such as compression of production period, increase of device complexity, construction difficulty, safety and engineering quality control. In order to cope with these challenges, the application of large chemical device modularization is gradually adopted by more and more domestic and foreign projects.

[0003] Large chemical device modularization not only brings comprehensive benefits in engineering progress, quality, safety, cost and other aspects, but also represents a new trend of development of large chemical device construction industry at home and abroad.

[0004] Module hoisting in place is the main way of module field installation. After the traditional module hoisting node completes the module in place, it needs to be removed (welded or bolted) to assemble the upper module. This practice increases the construction link and affects the module installation efficiency and construction cost.

[0005] With the large-scale of modules, the size and weight of modules gradually increase. Due to the size of process equipment and the requirements of module transportation, modules are generally divided into multiple layers. Module hoisting point is the main stress point of module hoisting, and the larger the module weight is.

[0006] The traditional module lug adopts welding, and the lug plate is long and the welding amount is large, so the welding node plate is easy to deform. The lug adopts bolt connection, and the bolt size is large and the number is large, so the installation and removal are difficult.

[0007] And after the lower module is in place, the lug of the lower module needs to be removed (welded or bolted) before the upper module can be installed, which affects the module installation efficiency.

[0008] Therefore, the present application provides a large chemical device module hoisting lug node to solve the above problems. Practical new type content

[0009] In order to solve the above problems, the present application provides a large chemical device module hoisting lug node.

[0010] The large chemical device module hoisting lug node provided by the present application adopts the following technical scheme:

[0011] A large chemical device module hoisting lug node, comprising an upper layer module steel structure column and a lower layer module steel structure column,

[0012] The lug plate is embedded in the lower-layer modular steel structure column, the lug plate protrudes from the side surface of the lower-layer modular steel structure column, and the lug hole of the lug plate protrudes from the top of the lower-layer modular steel structure column.

[0013] The maximum width of the lug plate protruding from the top is less than or equal to the maximum size of the inner diameter of the upper-layer modular steel structure column, and the upper-layer modular steel structure column and the lower-layer modular steel structure column are both hollow structures; in the stacked state, the upper-layer modular steel structure column is stacked on the upper part of the lower-layer modular steel structure column, and the lug plate protruding from the top of the lower-layer modular steel structure column is located in the hollow part of the upper-layer modular steel structure column.

[0014] Further, the lug plate protrudes 50 mm from the side surface of the lower-layer modular steel structure column, and the lug hole of the lug plate protrudes 400 mm from the top surface of the lower-layer modular steel structure column; the length of the lug plate embedded in the lower-layer modular steel structure column is 470 mm.

[0015] Through the above technical solution, the distances of the lug plate protruding from the side surface and the top surface of the lower-layer modular steel structure column and the embedded length are determined, so that the lug can better adapt to the requirements of hoisting and module stacking while ensuring the stability of the structure.

[0016] This precise size design is beneficial to providing a suitable fulcrum for hoisting operations without affecting the installation of the module, further ensuring the smooth progress of the hoisting process and improving the efficiency of module installation.

[0017] Further, the type of the lug plate is an upper-narrow lower-wide structure type.

[0018] Through the above technical solution, the lug plate with an upper-narrow lower-wide structure can be more accurately and quickly inserted into the upper-layer modular steel structure column, thereby ensuring the safety and stability of the hoisting operation and facilitating the stability of the entire module splicing structure.

[0019] Further, a lower-layer module closed top plate is arranged between the top surface of the lower-layer module and the lug plate.

[0020] Through the above technical solution, on the one hand, the internal structure of the lower-layer modular steel structure column can be protected; on the other hand, the lug is embedded in the steel structure square column, the lug plate of the lug protrudes from the side surface of the square column and above the closed top plate of the square column, and the outside of the square column and the closed top plate facilitates welding, reduces the difficulty of welding, facilitates the quality control of welding, and reduces the welding deformation.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] (1) By avoiding the problem of dismantling large module lifting nodes, serving as a guide for upper module placement, reducing welding difficulty, and increasing the strength of module splicing nodes, the construction process is reduced, the stability and accuracy of the installation process are guaranteed, and the installation efficiency and quality are improved;

[0023] (2) The manufacturing difficulty and construction cost of the module hoisting nodes are reduced, while the strength and seismic performance of the module splicing nodes are increased, making the entire large-scale chemical plant more economical and structurally more stable during the construction process.

[0031] Example:

[0032] The following is combined with Figure 1 -3 Provide further details on this application.

[0033] The embodiment of the present application discloses a large-scale chemical plant module lifting lug node, comprising an upper module steel structure column 1 and a lower module steel structure column 2.

[0034] The lower module steel structure column 2 is embedded with a lug plate 3, the lug plate 3 protrudes from the side of the lower module steel structure column 2, and the lug hole of the lug plate 3 protrudes from the top of the lower module steel structure column 2;

[0035] The maximum width of the protruding top of the ear plate 3 is less than or equal to the maximum inner diameter of the upper module steel structure column 1, and the upper module steel structure column 1 and the lower module steel structure column 2 are both hollow structures; when in the stacked state, the upper module steel structure column 1 is stacked on the upper part of the lower module steel structure column 2, and the top of the ear plate 3 protruding from the lower module steel structure column 2 is located in the hollow part of the upper module steel structure column 1.

[0036] See also Figure 1 、 Figure 2 and Figure 3 The ear plate of the ear plate 3 protrudes 50mm from the side of the lower module steel structure column 2, and the ear hole of the ear plate 3 protrudes 400mm from the top surface of the lower module steel structure column 2; the length of the ear plate 3 embedded in the lower module steel structure column 2 is 470mm.

[0037] Through the above technical solution, the distance between the lifting ear plate 3 and the top surface of the lower module steel structure column 2 and the embedded length are clarified, so that the lifting ear can better adapt to the needs of lifting and module stacking while ensuring structural stability.

[0038] This precise dimensional design is conducive to providing a suitable fulcrum for lifting operations without affecting module installation, further ensuring the smooth progress of the lifting process and improving module installation efficiency.

[0039] See also Figure 1 、 Figure 2 and Figure 3The type of the ear plate 3 is a narrow-upper and wide-lower structure.

[0040] Through the above technical solution, the ear plate 3 which is narrow at the top and wide at the bottom can be inserted into the upper module steel structure column 1 more accurately and quickly, thereby ensuring the safety and stability of the lifting operation, and at the same time helping to improve the stability of the entire module splicing structure.

[0041] See also Figure 1 、 Figure 2 and Figure 3 A lower module closed top plate 4 is provided between the top surface of the lower module and the lug plate 3 .

[0042] Through the above technical solution, on the one hand, the internal structure of the lower module steel structure column 2 can be protected; on the other hand, the lifting lug is embedded in the steel structure square column, and the lifting lug ear plate protrudes from the side of the square column and above the closed top plate of the square column, which facilitates welding on the outside of the square column and the closed top plate, reduces welding difficulty, facilitates welding quality control, and reduces welding deformation.

[0043] The implementation principle of a large-scale chemical plant module lifting lug node in the embodiment of the present application is as follows:

[0044] During module installation, a lug plate is embedded in the lower module steel column. The lug plate protrudes from the side of the lower module steel column for connecting the lifting rope, and the lug hole protrudes from the top of the lower module steel column. Because the maximum width of the lug plate's protruding top is less than or equal to the maximum inner diameter of the upper module steel column, and both the upper and lower module steel columns are hollow, when the upper module steel column is stacked on top of the lower module steel column, the lug plate's protruding top portion of the lower module steel column is located within the hollow portion of the upper module steel column. This eliminates the need to remove the lug after installation, and the lug also serves as a guide for positioning the upper module. The closed design of the module column top plate facilitates welding on the outside of the square column and the closed top plate, reducing welding deformation. Retaining the lug plate also increases the strength of the module joints and improves seismic performance, thereby achieving a series of beneficial effects, including improving module installation efficiency and reducing costs.

[0045] The lug plate of the present application cleverly utilizes the requirements for connecting the upper and lower sections of the square column, and the lug plate is embedded in the closed top plate of the lower module steel structure square column. The protruding lug part can be directly inserted into the upper module steel structure square column. After the lifting is completed, there is no need to remove it. At the same time, the lug plate serves as a guide when the upper module is in place, which facilitates the module docking, increases the strength of the module column top plate, reduces the module lifting construction process, improves the efficiency of module installation, and reduces construction costs.

[0046] This application solves the problem that traditional module lifting ears need to be removed after they are put into place, reduces the difficulty of manufacturing module lifting nodes, reduces the process of module lifting construction, improves the efficiency of module installation, and reduces construction costs.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
