Description

Technical Field

[0001] This invention relates to the field of gas holder manufacturing technology, specifically to a modular assembly device and method for gas holder side panels. Background Technology

[0002] Gas holders are widely used in industries such as metallurgy, petroleum, and natural gas, especially in steelmaking, ironmaking, and coking, where gas production and use are involved. Gas holders are cylindrical in shape and store and release gas through the up-and-down movement of an internal circular piston. Their storage principle relies on a sealed space composed of four main components: a base plate, side plates, columns, and the piston. During use, they play a role in stabilizing pressure, saving energy, and protecting the environment. Because the piston moves within the cylindrical space formed by the side plates and columns, the construction of the cylinder formed by the side plates and columns is crucial to ensure smooth and stable movement of the piston and safe operation of the gas holder.

[0003] In the past, the side plates were installed and welded separately at high altitudes. The working space was small and the amount of welding was large during high-altitude construction. Since the side plates are thin plate structures, the size of the cylinder formed by each layer of side plates after welding is different. The circles formed by the upper and lower parts of the cylinder are irregular, which causes defects such as difficulty in piston operation and short service life of gas holder. The radius of the cylinder structure cannot be effectively controlled. To address this, we propose a modular assembly device for gas holder side plates. Summary of the Invention

[0004] The purpose of this invention is to provide a modular assembly device and method for gas holder side panels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular assembly device for gas holder side panels, comprising four frame beams, which are welded together. Multiple equidistant frame columns are fixedly connected to the bottom of the frame beams on the left and right sides. Multiple equidistant horizontal secondary frame beams are fixedly connected to the inner sides of the frame beams on the left and right sides. A vertical secondary frame beam is fixedly connected to the middle of the inner sides of the frame beams on the front and rear sides. A modular shaping plate is fixedly connected to the top of each secondary frame beam.

[0006] Preferably, the bottom of the vertical secondary beam of the frame is fixedly connected with multiple equally spaced support columns, and the bottom middle of the frame beams on the front and rear sides is fixedly connected with support columns to increase the strength of the secondary beam of the frame and prevent deformation of the secondary beam of the frame due to the weight of the side plate modules. The support columns and the frame columns have the same height, which is 800-1200mm, which facilitates personnel to assemble and weld on the ground and reduces the amount of high-altitude work.

[0007] Preferably, the module shaping plate has an arc-shaped structure, and multiple equidistant reinforcing ribs are fixedly connected to the outer side of the module shaping plate.

[0008] Preferably, the reinforcing rib is an angle steel, and the top of the reinforcing rib is flush with the top of the module shaping plate.

[0009] Preferably, a limiting head is fixedly connected to the top of the frame beam and at the corresponding position of the frame column, and the height of the limiting head is ≤300mm.

[0010] Preferably, it also includes a side panel module, which includes a column, side panels and T-shaped steel. A T-shaped steel is installed on the outside of the two side panels for reinforcement, and the number of side panels and T-shaped steel is determined according to the height of the column. The main body of the module formed at this time is the side panel module.

[0011] Preferably, a limiting plate is fixedly connected to the surface of the limiting card head and the side near the secondary beam of the jig. The limiting plate and the module shaping plate are on the same horizontal plane, and the arc length between the limiting plates is the same as the arc length of the side plate.

[0012] A method for modularly assembling gas holder side panels using a modular assembly device includes the following steps: Step 1: Press and fabricate single side panels according to the structural radius and chord height of the inner wall of the gas holder side panel; press and fabricate T-shaped steel according to the structural radius and chord height of the outer wall of the gas holder side panel. Step 2: The two completed side panels are placed on the modular assembly device for the gas holder side panels. The bottom surface of the side panel and the module shaping plate are tightly fitted together. The edge of the side panel connecting column is snapped and fixed to the bottom of the limiting plate. At this time, the side panel is placed and fixed on the modular assembly device for the gas holder side panels. Step 3: Following Step 2, continue laying the side panels on the modular assembly device for the gas holder side panels, leaving a 4mm gap between the two side panels. Align and fix the center line of the T-shaped steel flange plate with the joint between the two side panels. Weld the joint between the two side panels and the fillet weld at the connection between the T-shaped steel and the side panels. At this point, the two side panels and the T-shaped steel form a whole. According to the dimensions of the segmented columns, assemble the other side panels and T-shaped steels one after another until the dimensions of the segmented columns are reached. This completes the side panel module assembly work.

[0013] Preferably, the manufacturing site should have enough operating space for the assembly of at least two side panel modules, and the site should be flat and firm to ensure the flatness and stability of the gas holder side panel modular assembly device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) By adopting a modular assembly device for the gas holder side panels and assembling them on a horizontal ground, the side panels can be constructed in a modular manner. This allows for effective control of the chord height, radius, and other dimensions of the curved structure of the side panels. Furthermore, considering the characteristics of thin plate structures and the large amount of welding work, welding shrinkage and deformation can be controlled in advance, thus ensuring effective quality control of the gas holder side panel installation.

[0015] 2) By using the modular assembly method for the cabinet side panels, the side panels can be installed as a whole, which changes the conventional high-altitude single-piece installation method. The overall manufacturing precision is controlled by the modular assembly method, thereby improving the installation precision of the side panels, reducing cost investment, improving construction efficiency, and shortening the construction period.

[0016] 3) By using the modular assembly method of side panels, the time for workers to install and weld at high altitudes is reduced, the construction risks caused by the narrow working area at high altitudes are reduced, the installation work is simplified, the service life of manpower and machinery is shortened, and the construction cost is reduced.
