Description

Technical Field

[0001] The invention relates to the technical field of coke oven installation, and in particular to a coke oven column positioning method. Background Art

[0002] As the main equipment for coking, the coke oven is also developing towards large-scale, environmentally friendly and automated. Among them, the installation position of the coke oven column is very critical. Due to the large size of the column and the long intervals between the columns, installation deviations are prone to occur during installation, resulting in column spacing that is inconsistent with the design. After the installation deviation occurs, it often requires the cooperation of multiple people to use jacks, winches, wire ropes and other tools to further adjust the position of the column, and it is difficult to ensure that the adjustment is in place at one time. It often requires multiple and repeated adjustments, which is time-consuming and labor-intensive, and the construction cost is high. At the same time, the coke oven masonry project needs to set up a heat preservation shed during winter construction. After the warm shed is set up, both sides of the column are covered with loading operation platforms, which further reduces the construction space and makes it impossible to use more manpower to fine-tune the deviated column, further exacerbating the difficulty of construction. Summary of the invention

[0003] The present invention aims to solve the above-mentioned problems, thereby providing a temporary support removal method for cantilever steel structure construction, which has high operability, safer operation and will not damage the top cantilever steel structure.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution: A coke oven column adjustment method comprises the following steps: S1: According to the displacement amount of the furnace column that needs to be fine-tuned, an adjustment tool is manufactured, wherein the adjustment tool is a Z-shaped structure, including a first vertical portion, a second vertical portion and a horizontal portion; S2: Place the adjustment tool on the coke oven foundation, with the horizontal part close to the top surface of the coke oven foundation, and the first vertical part inserted between the coke oven foundation and the oven column, close to the side wall of the coke oven foundation; S3: Place the jack sideways on the second vertical part, adjust the jack so that the output end of the jack is close to the side wall of the furnace column, and prepare for lifting; S4: Loosen the fixing bolts at the bottom of the furnace column; S5: The jack is lifted, and the output end of the jack presses against the furnace column, pushing the furnace column to the preset position; S6: Install the fixing bolts at the bottom of the furnace column to fix the furnace column, slowly loosen the jack, and take out the adjustment tool.

[0005] Preferably, a further technical solution of the present invention is: In step S2, a buffer rubber pad is installed between the horizontal portion and the top surface of the coke oven foundation, and between the first vertical portion and the side wall of the coke oven foundation; In step S3, a support frame is provided on a side of the second vertical portion away from the jack.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: This method solves the technical difficulties of fine-tuning the furnace column. It has a fast construction speed and high efficiency. It does not require a large construction space and has low requirements for construction space. The furnace column installation position can be fine-tuned without dismantling the greenhouse support structure. At the same time, the adjustment tool can be used repeatedly and in a turnover manner, thereby reducing costs and increasing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described below in conjunction with embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0010] like Figures 1 to 3 As shown, this embodiment provides a coke oven column adjustment method, comprising the following steps: S1: According to the displacement amount that the furnace column 3 needs to be fine-tuned, an adjustment tool 1 is manufactured. The adjustment tool 1 is a Z-shaped structure, including a first vertical portion 102, a second vertical portion 103 and a horizontal portion 101; wherein, the adjustment tool 1 is made of a steel plate with t=10~18mm, or is made of waste H-shaped steel heads above HM350*250, the size of the horizontal portion 101 is 250mm*350mm, and the sizes of the first vertical portion 102 and the second vertical portion 103 are both 250mm*250mm; the sizes of the horizontal portion 101, the first vertical portion 102, and the second vertical portion 103 are manufactured according to the displacement amount of fine-tuning. In this embodiment, the adjustment tool 1 can fine-tune the furnace column by 30~50mm.
