Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and specifically relates to an installation method for a ring furnace. Background Technology

[0002] In the installation and construction of ring furnace equipment, the bolt installation of the ring furnace foundation typically employs a pre-drilled hole design. The cross-sectional dimensions of the pre-drilled holes for the equipment bolts are generally between 200mm and 400mm, while the cross-sectional dimensions of the foundation pre-drilled holes are in the range of 300mm to 500mm. These pre-drilled holes are generally quite deep, reaching a maximum depth of 800mm. According to design requirements, the pre-drilled holes must be straight and their cross-sectional dimensions must meet design standards to ensure the accuracy requirements of the ring furnace equipment installation.

[0003] However, current construction methods for forming the aforementioned pre-reserved holes all have significant drawbacks. These mainly manifest in the inability to effectively guarantee the verticality of the formed holes, and the difficulty in precisely controlling the consistency between the actual size of the holes and the design dimensions. These problems necessitate substantial manpower for adjustments and corrections during construction, significantly increasing construction costs. More seriously, these construction defects often prevent the smooth installation of the annular furnace equipment, resulting not only in significant economic losses but also severely impacting the overall construction progress. Summary of the Invention

[0004] To address the sagging issues present in the installation and construction of existing annular furnace equipment, this invention provides an installation method for annular furnace equipment to improve the forming quality of reserved holes and ensure the smooth installation of the annular furnace equipment.

[0005] The specific technical solution adopted by this invention is as follows:

[0006] An installation method for a ring furnace includes the following steps:

[0007] Step S1: Based on the design drawings of the ring furnace equipment foundation, use measuring instruments to lay out the benchmark in the construction area, accurately locate the three-dimensional coordinates of the bottom opening of each reserved bolt hole, and mark the center line of the hole using the crosshair marking method.

[0008] Step S2: Provide a corrugated pipe that meets the design strength requirements as a bolt sleeve, and seal the bottom of the corrugated pipe;

[0009] Step S3: Make a matching fixed bracket sleeve according to the outer diameter and height of the corrugated pipe. The fixed bracket sleeve includes a top ring, a bottom ring and a vertical rod connecting the two. At least two support rods are welded to the inner side of the bottom ring.

[0010] Step S4: The corrugated pipe is coaxially placed inside the fixed bracket sleeve to form a corrugated pipe assembly, and the top of the corrugated pipe is sealed with tape; then the assembled corrugated pipe assembly is hoisted to the reserved bolt holes, adjusted to the design elevation and verticality and temporarily fixed, and then the foundation concrete of the ring furnace equipment is poured to embed the corrugated pipe assembly in the foundation of the ring furnace equipment.

[0011] Step S5: Remove the tape on the top of the corrugated pipe, hoist the ring furnace equipment onto the equipment foundation, adjust the levelness using the leveling device, and ensure that the bolt holes of the ring furnace equipment and the corrugated pipe are coaxially aligned, with the coaxiality error controlled within ±2mm.

[0012] Step S6: Simultaneously insert the installation bolts into the bolt holes and the inside of the corrugated pipe of the ring furnace equipment. After adjusting the verticality of the installation bolts, pour concrete into the corrugated pipe until the top surface of the concrete is flush with the bottom surface of the equipment foundation to complete the installation.

[0013] In some embodiments, the top ring and the bottom ring are made of round steel.

[0014] In some embodiments, both the vertical rod and the support rod are made of threaded steel.

[0015] In some embodiments, four vertical rods are provided, and the vertical rods are evenly distributed.

[0016] In some embodiments, the inner diameter of the fixed support sleeve is the same as the outer diameter of the bellows, and the height of the vertical rod of the fixed support sleeve is the same as the height of the bellows.

[0017] In some embodiments, the wall thickness of the bellows is not less than 5 mm.

[0018] In some of these embodiments, the bellows is made of stainless steel.

[0019] Compared with the prior art, the present invention has at least one of the following advantages or beneficial effects:

[0020] 1. High construction precision: The precise positioning of hole coordinates and crosshair center lines through benchmark layout, combined with the fixing of the corrugated pipe by the fixed bracket sleeve, can effectively ensure the verticality and cross-sectional dimension accuracy of the reserved hole, solve the problem of poor hole quality in traditional drilling, and ensure that the coaxiality error between the equipment bolt hole and the corrugated pipe is ≤±2mm, ensuring smooth bolt installation.

[0021] 2. Low construction cost: Using corrugated pipes as bolt sleeves, combined with customized fixing bracket sleeves, construction is simple and does not require a lot of manpower to correct holes, reducing labor costs; at the same time, the hole forming quality is reliable, avoiding rework losses caused by obstruction of ring furnace equipment installation, further controlling the total cost.

[0022] 3. Guaranteed construction progress: High precision in hole forming ensures smooth installation of the ring furnace equipment, avoiding construction delays caused by hole quality issues, shortening the construction cycle, and ensuring the project progresses as planned.

[0026] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0027] like Figure 1 As shown in the figure, this embodiment discloses an installation method for a ring furnace, which includes the following steps:

[0028] Step S1: Based on the design drawings of the ring furnace equipment foundation, use a measuring instrument (such as a total station) to lay out the baseline in the construction area, accurately locate the X, Y, and Z three-dimensional coordinates of the bottom opening of each reserved bolt hole, and control the positioning error within ±1mm. After positioning, mark the center line of the hole using the crosshair marking method.

[0029] This ensures that the markings are clear and accurate, providing a precise basis for the subsequent installation of the corrugated pipe components.

[0030] Step S2: Provide a corrugated pipe that meets the design strength requirements as the bolt sleeve, and ensure the bottom of the corrugated pipe is sealed. Specifically, according to the design requirements, a 6mm thick 304 stainless steel corrugated pipe is selected as the bolt sleeve, and its strength has been tested and meets the design requirements.

[0031] Step S3: Fabricate a matching fixing bracket sleeve based on the outer diameter and height of the corrugated pipe, such as... Figure 2The fixed support sleeve shown includes a top ring 1, a bottom ring 2, and vertical rods 3 connecting the two. Two support rods 4 are welded to the inner side of the bottom ring 1 to support the bottom of the bellows. The inner diameter of the fixed support sleeve is the same as the outer diameter of the bellows, and the height of the vertical rods 3 of the fixed support sleeve is the same as the height of the bellows. Specifically, four vertical rods 3 are provided and evenly distributed. The vertical rods 3 are made of φ12 threaded steel. Both the top ring 1 and the bottom ring 2 are made of φ10 round steel. Two threaded steel rods with a diameter of 10mm are welded to the inner side of the bottom ring 2 as support rods 4. The two support rods 4 are arranged in a cross shape, and the welding length is not less than 100mm, so that all parts of the fixed support sleeve are connected as a whole to increase rigidity.

[0032] Step S4: Coaxially insert the corrugated pipe into the completed fixed bracket sleeve to form a corrugated pipe assembly. The top of the corrugated pipe is flush with the top of the fixed bracket sleeve, and the top of the corrugated pipe is sealed with waterproof tape to ensure a reliable seal and prevent cement slurry from entering the corrugated pipe during subsequent concrete pouring. Then, use a small crane to lift the assembled corrugated pipe assembly to the reserved bolt holes. Adjust the position of the assembly according to the cross center line marked in Step 1 so that its center line coincides with the center line of the hole. After adjusting to the design elevation and verticality, temporarily fix it. Then, pour the foundation concrete of the annular furnace equipment to pre-embed the corrugated pipe assembly in the foundation of the annular furnace equipment. During the concrete pouring process, take care to avoid direct collision of the vibrator with the assembly to prevent displacement.

[0033] Step S5: After the concrete of the pre-embedded corrugated pipe assembly reaches 70% of the design strength, remove the waterproof tape on the top of the corrugated pipe, hoist the ring furnace equipment onto the equipment foundation, adjust the levelness using a leveling device, and ensure that the bolt holes of the ring furnace equipment and the corrugated pipe are coaxially aligned, with the coaxiality error controlled within ±2mm.

[0034] Step S6: Simultaneously insert the installation bolts into the bolt holes and the inside of the corrugated pipe of the ring furnace equipment. After adjusting the verticality of the installation bolts, pour concrete (C40 fine stone concrete) into the corrugated pipe until the top surface of the concrete is flush with the bottom surface of the equipment foundation. After the concrete reaches the design strength, the installation of the ring furnace equipment is completed.

[0035] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
