Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, and in particular to a drum-shaped filter screen installation platform. Background Technology

[0002] Drum screens are core filtration devices in the circulating water systems of nuclear power plants and thermal power plants. They are mainly used to remove suspended solids (such as marine organisms, aquatic plants, and plastics) from seawater or freshwater, ensuring the safe operation of the cooling water system. A typical drum screen consists of a main shaft, a flange, and a frame structure mounted on the flange. The flange is mounted on the main shaft, and the frame structure consists of multiple structures evenly distributed along the circumference of the flange.

[0003] Currently, the widely used installation method for drum-shaped filters is as follows: scaffolding is erected before the installation of the frame structure. The frame structure is then installed on the scaffolding. After the installation of a single frame structure is completed, the scaffolding is dismantled. The main shaft is then rotated to the empty position for the installation of the next frame structure. The scaffolding is then re-erected, and the installation of the next frame structure begins.

[0004] The installation method of drum-shaped filter screen requires frequent erection and dismantling of scaffolding, which consumes a lot of manpower and material resources, prolongs the construction period, and brings many safety hazards during the frequent erection and dismantling of scaffolding, such as unstable scaffolding and increased risks for workers working at heights.

[0005] With the expansion of modern construction projects and the improvement of construction requirements, the installation technology of drum-shaped filters urgently needs improvement. There is an urgent need for a reasonably designed, easy-to-operate, efficient and safe drum-shaped filter installation platform to provide innovative solutions for the construction industry.

[0006] Therefore, this application provides a new drum-shaped filter installation platform to address the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a drum-shaped filter screen installation platform, so as to make the installation of the drum-shaped filter screen frame structure convenient and efficient, reduce the safety risks of operation, and reduce the amount of scaffolding erection and dismantling work.

[0008] To achieve the above objectives, this utility model provides a drum-shaped filter installation platform. The drum-shaped filter installation platform includes a movable platform for operator movement. The movable platform is provided with a connector for fixed connection to the main shaft of the drum-shaped filter. The movable platform is also connected to a fixing member via a cantilever. The cantilever can rotate relative to the movable platform and be locked. The cantilever can extend from the gap between the skeleton structures of the drum-shaped filter to the scaffolding on the rear side of the drum-shaped filter. At this time, the fixing member can be detachably connected to the scaffolding.

[0009] Furthermore, the connecting member is a connecting sleeve that matches the outer diameter of the spindle. The connecting sleeve includes a fixed part that is fixed to the movable platform and a movable part that is connected to the fixed part and can rotate relative to the fixed part. The fixed part and the movable part can be connected by a threaded connector.

[0010] Furthermore, the fastener is a hook.

[0011] Furthermore, the fixing member and the cantilever assembly form a fixing component, and the fixing component is provided in two sets, with the two sets of fixing components respectively located on both sides of the movable platform.

[0012] Furthermore, the drum-shaped filter installation platform also includes a connecting frame, and the cantilever is connected to the movable platform through the connecting frame. The cantilever can rotate and lock relative to the connecting frame.

[0013] Furthermore, the connecting frame includes a column and a diagonal brace, the cantilever is connected to the movable platform through the column, and the diagonal brace is connected between the column and the movable platform.

[0014] Furthermore, the cantilever is rotatably connected to the column;

[0015] The cantilever is provided with a first pin hole, and the column is provided with a second pin hole. When the cantilever extends from the gap between the skeleton structures of the drum-shaped filter to the scaffold behind the drum-shaped filter, the first pin hole and the second pin hole correspond to each other, and the pin can pass through the first pin hole and the second pin hole in sequence.

[0016] Furthermore, the activity platform includes a platform for operator activities, and a kickboard is provided on the platform.

[0017] Furthermore, a protective railing is also installed on the platform.

[0018] Furthermore, a reinforcing frame is provided at the bottom of the platform, and the connector is connected to the reinforcing frame.

[0019] By adopting the above technical solution, the drum-shaped filter screen installation platform of this utility model has at least the following beneficial effects:

[0020] It should be noted that before installing the frame structure of the drum-shaped filter using the installation platform of this embodiment, scaffolding must first be erected on the rear side of the drum-shaped filter to assist in the use of the installation platform. Specifically, when the main shaft of the drum-shaped filter is horizontally positioned, the two sides of the drum-shaped filter are the front and rear sides, respectively, along the axial direction of the main shaft. The scaffolding is erected on the rear side, and the installation platform is positioned on the front side of the drum-shaped filter.

[0021] The installation platform usage process in this embodiment is as follows:

[0022] Step one: First, fix the connector to the main shaft of the drum filter screen, and extend the cantilever from the front side through the gap between the skeleton structures of the drum filter screen to the scaffolding at the rear side of the drum filter screen. At this time, the fixing part reaches the scaffolding. Then, connect the fixing part to the scaffolding and lock the position of the cantilever to effectively prevent the installation platform from rotating during subsequent operations and provide a stable working foundation for the operators.

[0023] Step two: The operator enters the movable platform to install the drum-shaped filter frame structure. After the task is completed, the operator leaves the movable platform. At this time, the cantilever is unlocked, and the fixing parts are removed from the scaffold. Then, the cantilever is rotated relative to the movable platform to a position that does not affect the rotation of the main shaft, such as making the cantilever vertically upright relative to the movable platform. This prepares for the subsequent rotation of the drum-shaped filter and prevents the cantilever from interfering with the rotation of the main shaft.

[0024] Step 3: Activate the drive mechanism of the drum filter to rotate it to the next working position. During the rotation of the drum filter, the installation platform will rotate along with the main shaft of the drum filter because it is fixed to the main shaft via a connector. After the drum filter stops rotating to the next working position, the main shaft will rotate to the next available position for the frame structure installation. The operator will then disassemble the connector from the main shaft or loosen the connector from the main shaft, and then rotate the movable platform relative to the main shaft until it is gradually adjusted to a horizontal position. The connector will then be fixed to the main shaft again, and the cantilever will be re-inserted from the front through the gap between the drum filter's frame structures to the scaffolding at the rear of the drum filter. The fixing piece will then be connected to the scaffolding, and the position of the cantilever will be locked to ensure the stability of the installation platform during subsequent operations.

[0025] Step four: After adjusting and securing the installation platform, the operator re-enters the platform to begin installing the drum-shaped filter frame structure at the next location. This process is repeated until all drum-shaped filter frame structures are installed.

[0026] In summary, using the installation platform of this embodiment, only one scaffolding setup and dismantling is required, eliminating the need for frequent disassembly and assembly. After each frame structure is installed, only minor adjustments to the movable platform are needed after the main shaft rotates, greatly reducing installation time and costs. This makes the overall installation process of the drum filter screen more convenient, compact, and efficient. Furthermore, the elimination of frequent scaffolding disassembly and assembly also reduces the operational safety risks for operators. Attached Figure Description

[0041] Example

[0042] Please see Figure 1 This embodiment provides a drum-shaped filter installation platform, which includes a movable platform 1 for operator movement. The movable platform 1 is provided with a connector 2 for fixed connection with the main shaft of the drum-shaped filter. The movable platform 1 is also connected to a fixing member 4 via a cantilever 3. The cantilever 3 can rotate relative to the movable platform 1 and be locked. The cantilever 3 can extend from the gap between the skeleton structures of the drum-shaped filter to the scaffold on the rear side of the drum-shaped filter. At this time, the fixing member 4 can be detachably connected to the scaffold.

[0043] It should be noted that before installing the frame structure of the drum-shaped filter using the installation platform of this embodiment, scaffolding must first be erected on the rear side of the drum-shaped filter to assist in the use of the installation platform. Specifically, when the main shaft of the drum-shaped filter is horizontally positioned, the two sides of the drum-shaped filter are the front and rear sides, respectively, along the axial direction of the main shaft. The scaffolding is erected on the rear side, and the installation platform is positioned on the front side of the drum-shaped filter.

[0044] The installation platform usage process in this embodiment is as follows:

[0045] Step 1: First, connect the connector 2 to the main shaft of the drum filter screen, and extend the cantilever 3 from the front through the gap between the skeleton structures of the drum filter screen to the scaffolding at the rear of the drum filter screen. At this time, the fixing part 4 reaches the scaffolding. Then, connect the fixing part 4 to the scaffolding and lock the position of the cantilever 3. This effectively prevents the installation platform from rotating during subsequent operations and provides a stable working foundation for the operators.

[0046] Step two: The operator enters the movable platform 1 to install the drum-shaped filter frame structure. After the task is completed, the operator leaves the movable platform 1. At this time, the cantilever 3 is unlocked, and the fixing part 4 is removed from the scaffold. Then, the cantilever 3 is rotated relative to the movable platform 1 so that the cantilever 3 is rotated to a position that does not affect the rotation of the main shaft, such as making the cantilever 3 vertically upright relative to the movable platform 1, in preparation for the subsequent rotation of the drum-shaped filter and to prevent the cantilever 3 from interfering with the rotation of the main shaft.

[0047] Step 3: Activate the drive mechanism of the drum filter to rotate it to the next working position. During the rotation of the drum filter, the installation platform will rotate along with the main shaft of the drum filter because it is fixed to the main shaft via connector 2. After the drum filter stops rotating to the next working position, the main shaft will rotate to the next available position for the frame structure installation. The operator will then disassemble connector 2 from the main shaft or loosen connector 2 from the main shaft, and rotate the movable platform 1 relative to the main shaft until it is gradually adjusted to a horizontal position. Then, reconnect connector 2 to the main shaft, and re-insert the cantilever 3 from the front through the gap between the frame structures of the drum filter to the scaffolding at the rear of the drum filter. Finally, connect the fixing piece 4 to the scaffolding and lock the position of the cantilever 3 to ensure the stability of the installation platform during subsequent operations.

[0048] Step four: After adjusting and securing the installation platform, the operator re-enters the active platform 1 to begin installing the drum-shaped filter frame structure at the next location. This process is repeated until all drum-shaped filter frame structures are installed.

[0049] In summary, using the installation platform of this embodiment, only one scaffolding setup and dismantling is required, eliminating the need for frequent disassembly and assembly. After each frame structure is installed, only minor adjustments to the movable platform 1 are needed after the main shaft rotates, greatly reducing installation time and costs. This makes the overall installation process of the drum filter screen more convenient, compact, and efficient. Furthermore, the elimination of frequent scaffolding setup and dismantling also reduces the operational safety risks for operators.

[0050] Preferably, please refer to Figure 2 In this embodiment, the connector 2 is a connecting sleeve that matches the outer diameter of the spindle. The connecting sleeve includes a fixed part 21 fixed to the movable platform 1 and a movable part 22 connected to the fixed part 21 and capable of rotating relative to the fixed part 21. The fixed part 21 and the movable part 22 can be connected by a threaded connector 2.

[0051] With this setup, when the connecting sleeve needs to be fixed to the spindle, loosen or unscrew the threaded connector 2, allowing the movable part 22 to rotate away from the fixed part 21. Then, place the connecting sleeve onto the spindle, and then rotate the movable part 22 towards the fixed part 21, tightening the threaded connector 2. When the movable platform 1 needs to rotate relative to the spindle, loosen the threaded connector 2, allowing the movable part 22 to rotate away from the fixed part 21, increasing the gap between the movable part 22 and the fixed part 21 to be greater than the outer diameter of the spindle. At this point, the connecting sleeve can rotate relative to the spindle until the movable platform 1 gradually rotates and adjusts to a horizontal state. Tightening the threaded connector 2 then fixes the connecting sleeve to the spindle.

[0052] This form of connector 2 makes the connection and disassembly of connector 2 with the main shaft convenient and simple. When it is necessary to rotate the movable platform 1, there is no need to remove the connecting sleeve from the main shaft. You only need to loosen the threaded connector 2. This further improves the convenience of operation, reduces installation time and cost, and makes the overall installation process of the drum filter screen more convenient, compact and efficient.

[0053] Preferably, please refer to Figure 1 In this embodiment, the fixing component 4 is a hook. It should be noted that the hook plays a fixing role. The hook is hooked to the scaffolding erected inside the building behind the drum-shaped filter screen main shaft, ensuring that the movable platform 1 will not sway left and right on the main shaft, thus ensuring the stability of the movable platform 1 on the main shaft and ensuring the continuity and accuracy of the operation.

[0054] The hook design makes it easier to connect the fastener 4 to the scaffolding, and the connection with the scaffolding is more secure and reliable.

[0055] Preferably, please refer to Figure 3 In this embodiment, the fixing member 4 and the cantilever 3 are combined to form a fixing component. There are two sets of fixing components, which are respectively set on both sides of the movable platform 1.

[0056] With this setup, both sets of fixing components are connected to the back of the scaffolding, which further improves the safety of the installation platform for carrying operators and makes the installation of the platform more secure and reliable.

[0057] Preferably, please refer to Figure 3 In this embodiment, the drum-shaped filter installation platform also includes a connecting frame 5. The cantilever 3 is connected to the movable platform 1 through the connecting frame 5. The cantilever 3 can rotate and lock relative to the connecting frame 5.

[0058] This configuration makes the connection between the cantilever 3 and the mobile platform 1 more secure and reliable.

[0059] The cantilever 3 is used to connect the hook and the connecting frame 5, extending out from the gaps in the drum-shaped filter frame to connect the scaffold. After the frame structure is installed, the cantilever 3 can be rotated to a position that does not affect the rotation of the main shaft. Once the main shaft has rotated to the correct position, the cantilever 3 can be adjusted so that the hook is attached to the scaffold.

[0060] Preferably, please refer to Figure 1 In this embodiment, the connecting frame 5 includes a column 51 and a diagonal brace 52. The cantilever 3 is connected to the movable platform 1 through the column 51, and the diagonal brace 52 is connected between the column 51 and the movable platform 1.

[0061] The column 51 connects the cantilever 3 to the movable platform 1, and the diagonal brace 52 makes the connection between the column 51 and the movable platform 1 more reliable and secure.

[0062] Preferably, please refer to Figure 1 In this embodiment, the cantilever 3 and the column 51 are rotatably connected; the cantilever 3 is provided with a first pin hole, and the column 51 is provided with a second pin hole. When the cantilever 3 extends from the gap between the skeleton structure of the drum-shaped filter to the scaffold behind the drum-shaped filter, the first pin hole and the second pin hole correspond to each other, and the pin can pass through the first pin hole and the second pin hole in sequence.

[0063] For example, the rotatable connection between the cantilever 3 and the column 51 can be achieved through a hinge connection. The pins pass sequentially through the first and second pin holes, locking the position between the cantilever 3 and the column 51. This ensures that the cantilever 3 extends from the gaps in the frame structure of the drum-shaped filter into the scaffold behind the drum-shaped filter, making the support of the mobile platform 1 for the operator more stable and reliable.

[0064] Preferably, please refer to Figure 1 In this embodiment, the activity platform 1 includes a platform 11 for operator activities, and a kickboard 12 is provided on the platform 11. The upright 51 can be connected to the platform 11 or to the kickboard 12. The kickboard 12 is provided to ensure operator safety, reduce the risk of falls from heights and falling objects, and improve operator safety.

[0065] Preferably, please refer to Figure 1 In this embodiment, a protective railing 13 is also provided on the platform 11. The protective railing 13 is provided to ensure the safety of the workers, reduce the risk of falls from heights and falling objects, and improve the safety of the operators.

[0066] Preferably, please refer to Figure 1 In this embodiment, a reinforcing frame 6 is provided at the bottom of the platform 11, and the connector 2 is connected to the reinforcing frame 6.

[0067] For example, the reinforcing frame 6 includes a frame that is connected end to end along the circumference of the platform 11 and multiple staggered crossbeams arranged within the frame. The reinforcing frame 6 enhances the load-bearing capacity of the movable platform 1 and improves the safety of operation.

[0068] It should be added that the method of using the drum-shaped filter installation platform in this embodiment is as follows:

[0069] Step 1, Platform Fixing Steps: Loosen the threaded connector 2, put the connecting sleeve on the main shaft, and tighten the threaded connector 2 to firmly fix the connecting sleeve to the main shaft. Then rotate the cantilever 3 relative to the connecting frame 5 to lift the cantilever 3 and let the cantilever 3 extend from the gap between the drum-shaped filter screen skeleton structure to the scaffold. Connect the fixing piece 4 at the end of the cantilever 3 to the scaffold. For example, if the connecting frame 5 is a hook, hang the hook in a firm and reliable position on the scaffold.

[0070] Select a suitable pin and insert it into the first and second pin holes in sequence, ensuring that the pin is fully inserted and locked. This effectively prevents the installation platform from rotating during subsequent operations and provides a stable working foundation for the operator.

[0071] Step Two, Personnel Operation and Evacuation Procedures: Operators, wearing protective gear and carrying tools, enter the activity platform 1, confirm the wearing of their personal protective equipment, and check and adjust their tools; after confirming that everything is in order, they begin the installation of the drum-shaped filter frame structure according to the established work procedures and technical specifications; after the work is completed, operators leave the activity platform 1 safely and orderly in the reverse order of entering the platform.

[0072] Step 3, Adjustment of cantilever 3: After the operator leaves the active platform 1, pull out the pin on cantilever 3. During the pulling process, pay close attention to the state of the pin to ensure that it is pulled out smoothly without deformation or damage. After pulling out the pin, slowly and steadily remove the fixing part 4 from the scaffold. For example, when the connecting part 2 is a hook, be careful to avoid the hook colliding with surrounding objects and causing damage. Then rotate cantilever 3 relative to the connecting frame 5, so that cantilever 3 rotates to a position that does not affect the rotation of the main shaft. For example, make cantilever 3 vertically upright relative to the connecting frame 5. At this time, cantilever 3 and the column 51 of the connecting frame 5 form a 180° angle, which prepares for the subsequent rotation of the drum filter and prevents cantilever 3 from interfering with the rotation of the main shaft.

[0073] Step 4, Drum Filter Rotation: Start the drive device of the drum filter to slowly rotate it to the next working position. During the rotation of the drum filter, the mounting platform will rotate along with the drum filter because it is connected to the main shaft of the drum filter through a connecting sleeve. Closely monitor the rotation of the drum filter and the mounting platform to ensure that the rotation is smooth and without jamming. If any abnormality occurs, stop the rotation immediately and troubleshoot the problem.

[0074] Step 5, Platform Adjustment and Fixing: After the drum filter screen stops rotating to the next working position, the operator adjusts the looseness of the threaded connector 2 so that the connecting sleeve can rotate relative to the main shaft until the movable platform 1 gradually rotates and adjusts to a horizontal state. Tighten the threaded connector 2 to fix the connecting sleeve to the main shaft. Then rotate the cantilever 3 relative to the connecting frame 5 to lift the cantilever 3. Then connect the fixing part 4 to the scaffold and lock the position of the cantilever 3 with the pin to ensure that the installation platform remains stable during subsequent operations.

[0075] Step Six, Next Stage of Work: After the installation platform is adjusted and secured, and after a safety inspection confirms that everything is in order, the operator enters the active platform 1 again and repeats the previous preparation work, such as checking protective equipment and adjusting the tools. Once everything is confirmed to be ready, the installation of the drum-shaped filter frame structure at the next location can begin. This process is repeated until all drum-shaped filter frame structures are installed.

[0076] In summary, this embodiment addresses the problems of difficult work surface layout and frequent scaffolding erection and dismantling in existing drum-shaped filter frame structure installation methods. It designs an installation platform for drum-shaped filters to solve the existing safety hazards and efficiency bottlenecks in drum-shaped filter installation. Through innovative structural design, it makes the installation of drum-shaped filter frame structures convenient and efficient, reduces operational safety risks, reduces the amount of scaffolding erection and dismantling work, and meets the strict requirements of building construction for drum-shaped filter frame installation.

[0077] The installation platform in this embodiment demonstrates several significant technical advantages, greatly facilitating and ensuring the safety of drum filter installation. Specific technical advantages are as follows:

[0078] Firstly, it significantly improves the installation efficiency of the drum-shaped filter screen frame structure. In the past, the installation of each frame structure required the erection and dismantling of scaffolding once, each time taking 30 minutes. That is, the installation of a single frame structure required 1 hour just for scaffolding setup.

[0079] The installation platform used in this embodiment is completely different. Once the installation platform is installed in place, it does not need to be frequently disassembled. Only minor adjustments to the movable platform 1 are required after the spindle rotates. The platform adjustment time is about 10 minutes, which greatly reduces the installation time cost and makes the overall installation process more compact and efficient.

[0080] Secondly, it comprehensively enhances operational safety. The installation platform adopted in this embodiment reduces the scaffolding erection process, eliminating the need for high-altitude operations. Personnel can adjust the platform device from both sides of the drum-shaped filter, fundamentally reducing the numerous safety risks caused by high-altitude scaffolding construction and frequent movement on scaffolding, thus providing a solid guarantee for the life safety of workers.

[0081] Thirdly, innovative design enables low-cost manufacturing. The installation platform has a simple structural design and can use structural steel as the main material, resulting in low manufacturing costs. It does not require complex processes or expensive equipment investment, effectively controlling manufacturing costs. It is both practical and economical, and has great market promotion value.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
