Description

Technical Field

[0001] The utility model relates to the technical field of coke oven construction engineering, in particular to a construction platform for modular production of process pipelines of a coke oven gas collection system. Background Art

[0002] During coke oven construction, a temporary coke oven masonry shed is installed. Two to three cranes are mounted on the roof of the shed, allowing for clearance between the cranes and the completed coke oven roof. Traditional construction methods often involve assembling and welding the gas header pipes into sections on the oven roof. These sections are then hoisted into place using a crane within the masonry shed and then welded together into a single piece. Subsequently, the steel structure operating platform, pipe supports, process piping, and electromechanical bridges are assembled piecemeal on the gas header pipes. This traditional construction method has numerous drawbacks: difficult to ensure quality, high-altitude construction risks and low efficiency, high labor costs, severe environmental pollution, and long construction times. Furthermore, with the diversification of production processes and the increasing diversity of oven types, the high cost of masonry sheds prevents the availability of multiple sheds for different oven types. When constructing larger ovens, using shed cranes to install the gas header pipes, operating platform, and process pipelines becomes difficult or impossible.

[0003] Patent publication number CN 114382951 A proposes a modular pipeline installation method. The steps are: determining the pipeline size, adjusting the position of the support rings within the mold frame according to the pipeline size, and adjusting the opening size of the support rings to ensure that the support rings fit the pipeline; securing the two support rings by securing them with tension bolts; installing the rubber rings by placing a rubber ring bag with glue at the pipeline socket. The rubber ring bag is arranged in a circle and adhered to the inner wall of the pipeline socket; installing the pipeline, butting the two mold frames together and fixing the two pipelines by plugging them together. After the rubber ring breaks, the glue is distributed at the pipeline connection point. This patent is intended to butt-join two pipeline sections. This solution only improves the docking quality of modular pipelines.

[0004] The total weight of the process pipelines in the gas collection system of a JNX-7.65 coke oven is approximately 390 tons. The pipelines must be installed with high precision, and their modular assembly requires high stability and support from the construction platform. Therefore, developing a construction platform suitable for the modular production and overall installation of the process pipelines in the coke oven gas collection system is a technical problem that needs to be solved urgently.

[0030] Example

[0031] See also Figure 1 The gas gathering system process pipeline includes the gas gathering pipe 1 and the operating platform 2 and process pipelines on it. Figures 2 to 5 This embodiment provides a construction platform for modular production of process pipelines of a coke oven gas collection system, including a support frame 3 at the bottom and a row of cross beams 6 thereon: preferably, the support frame 3 includes two rows of support columns 4 and horizontal and vertical beams 5 laid flat above them.

[0032] The spacing between the crossbeams 6 at both ends is no greater than the longitudinal length of the support frame 3 to ensure stable support for the upper portion. Preferably, the length of the crossbeams 6 is no greater than twice the width of the transverse and longitudinal beams 5 to ensure stable support for the lower support frame. The positions of the crossbeams 6 correspond to the positions of a set of columns 21 on the operating platform 2; the length of each crossbeam 6 is no less than twice the spacing between a set of columns 21.

[0033] A gas collecting pipe seat 7 is provided in the middle of each crossbeam 6 .

[0034] The construction platform is provided with a row of cross beams and gas collecting pipe seats on the cross beams on the bottom support frame, which respectively meet the precise support requirements of the operating platform and the gas collecting pipes, so that the process pipelines of the coke oven gas collecting system can be modularly assembled as a whole on the construction platform on the ground without the need to hoist the construction platform to the top of the coke oven.

[0035] As a preferred technical solution, the crossbeam 6 is made of I-beam, which is a common and easily available material.

[0036] As another preferred technical solution, the transverse and longitudinal beams 5 and the cross beam 6 are detachably fixedly connected to facilitate the recycling of the support frame after the cross beam is removed at a later time.

[0037] Taking the construction platform for modular production of process pipelines of the JNX-7.65 coke oven gas collection system as an example, the assembly steps of the construction platform are as follows:

[0038] Step 1: Determine the module segment lengths based on the design drawings and segmentation plan, and thus the platform length. Use the outer rail foundation of the pusher car as the platform assembly site to reduce site occupation and facilitate lifting. On a site that meets the requirements, lay out the horizontal and vertical control edges of the platform support columns according to the platform size plan.

[0039] Step 2: The support column 4 and the horizontal and vertical beams 5 are made of 350*350mm I-beams. Figure 6 , according to the layout, start from the middle and install the support column 4 and the horizontal and vertical beams 5 according to the platform plan, use the level to control the elevation of the horizontal and vertical beams 5, and use the total station or theodolite to control the longitudinal direction to ensure straightness. Figure 7 , sequentially install the support columns 4 and the horizontal and vertical beams 5 at both ends. Use a level to measure the top elevation of each support column 4. The elevation error between two columns should be no more than 1mm, and the elevation error between all five columns should be no more than 2mm. After completion, the overall elevation error should be no more than 2mm, and the error between the vertical beams should be no more than 2mm. Use a level to control the elevation of the horizontal and vertical beams 5, and use a total station or theodolite to control the vertical direction to ensure straightness.

[0040] Step 3: Install crossbeam 6 on the horizontal and vertical beams 5 according to the modular design of the gas gathering system and operating platform. Use a level to control the elevation of crossbeam 6 and a total station or theodolite to control its longitudinal direction to ensure straightness. Crossbeam 6 is made of 400 x 300 mm I-beam steel.

[0041] Step 4: Install the gas collecting pipe seat 7 on the crossbeam 6, use a level to control the elevation of the gas collecting pipe seat 7, and use a total station or theodolite to control the direction of the gas collecting pipe seat 7 to ensure it is straight. Figures 2 to 4 , the construction platform installation is completed.

[0042] When the construction platform is used, the gas collecting pipe 1 is first installed on the gas collecting pipe seat 7, and then the column 21 is installed on the beam 6. The operating platform 2 is installed on the column 21. The operating platform 2 and the column 21 are connected and fixed to the gas collecting pipe 1. Finally, the top structure of the operating platform and the process pipeline are installed.

[0043] It can be seen from this that the construction platform can meet the modular construction of the coke oven gas collection system and the operating platform, and can start the production of the coke oven gas collection system and the operating platform in a timely manner, ensuring that the gas collection pipes and process pipelines have sufficient processing and production time, while meeting the modular processing and production, ensuring that the positions of the gas collection pipes and process pipelines in each section are accurate and unified, and that precise docking is achieved when the sections are assembled into a whole, ensuring excellent quality.

[0044] In summary, the present invention provides a construction platform for modular production of process pipelines of a coke oven gas collection system, comprising a bottom support frame and a row of crossbeams thereon: the spacing between the crossbeams at both ends is no greater than the longitudinal length of the support frame; the positions of the crossbeams correspond one-to-one to the positions of a group of columns of the operating platform; the length of each crossbeam is no less than twice the spacing between a group of columns; and a gas collection pipe seat is provided in the middle of each crossbeam. The present invention provides precise support for the operating platform and the gas collection pipe by arranging a row of crossbeams and the gas collection pipe seats on the crossbeams on the bottom support frame, respectively, so that the process pipelines of the coke oven gas collection system can be modularly assembled as a whole on the ground on the construction platform, thereby improving construction quality and efficiency. It also eliminates the need to hoist the construction platform to the top of the coke oven, reducing safety risks.
