Description

Technical Field

[0001] This utility model relates to the field of marine engineering construction technology, specifically to a debris barrier installation device. Background Technology

[0002] Wastewater interception nets are an important type of environmental protection equipment, mainly used to intercept debris and solid waste in sewage to prevent them from entering water bodies and causing environmental pollution.

[0003] In nuclear power plant marine engineering construction, trash racks are typically installed on the steel casing of the pile foundation using steel lugs, and the steel casing is then used to secure the trash racks. During installation, the trash racks are usually first installed on the steel lugs, and then the lugs are fixed to the steel casing of the pile foundation.

[0004] The steel lugs are quite heavy. In existing technology, a crane vessel is typically used to attach the steel lugs to the steel casing of the pile foundation. Then, construction workers dive into the water to secure the lugs to the casing using bolts and other fasteners. However, in rough seas, the crane vessel is prone to swaying, which not only increases the difficulty and efficiency of installing the steel lugs but also increases the danger for construction workers operating in the water.

[0005] Therefore, designing a steel hanging lug installation device that is less affected by wind and waves and is easy to operate is of great significance for the installation of debris nets. Utility Model Content

[0006] In view of the shortcomings of the related technologies, this utility model provides a debris barrier installation device to increase the stability of the steel hanging ear installation process, improve the installation efficiency of the steel hanging ear, and reduce the danger of the steel hanging ear installation process.

[0007] This utility model provides a device for installing a debris barrier net, comprising:

[0008] Steel casing for pile foundations, which is installed vertically in seawater;

[0009] Steel lugs are fitted around the outer perimeter of the steel casing of the pile foundation and are used to install the trash rack.

[0010] A steel platform on the sea surface, located around the steel casing of the pile foundation;

[0011] The gantry crane is installed on a steel platform above water.

[0012] Pulley system, the pulley system includes:

[0013] Fixed pulley, which is installed on the gantry frame;

[0014] A movable pulley is located below the fixed pulley; the movable pulley is connected to a lifting hook, which is connected to a steel lug.

[0015] The rope has its first end fixedly connected to a movable pulley, and its second end is successively passed around a fixed pulley and a movable pulley.

[0016] Pull the second end of the rope to move the pulley and the lifting hook up and down, so that the steel hanging lug moves up and down along the steel casing of the pile foundation.

[0017] This technical solution facilitates the installation of steel lugs by installing pulley blocks on a gantry crane and using these pulley blocks to install steel lugs onto the steel casing of the pile foundation. By mounting the gantry crane on a steel platform on the water, the platform supports the gantry crane, preventing it from swaying on the sea surface and increasing the stability of the pulley blocks, thus enhancing the stability during steel lug installation. The pulley blocks are designed to include fixed pulleys, movable pulleys, and ropes. The fixed pulleys are installed on the gantry crane, and a lifting hook is connected to the steel lugs on the movable pulleys. The first end of the rope is connected to the movable pulley, and the rope is wound around the fixed and movable pulleys. Pulling the second end of the rope causes the rope to move the movable pulley and the lifting hook up and down, thereby moving the steel lugs up and down as well, ultimately allowing them to be installed onto the steel casing of the pile foundation.

[0018] In some embodiments, two gantry frames are provided, and the two gantry frames are arranged in parallel; the bottom of the gantry frames is connected to a base support, and the two gantry frames are connected to each other through the base support, which is set on a steel platform on the water.

[0019] This technical solution uses two parallel gantry frames connected by a base brace to form an integral structure, thereby improving the structural stability and load-bearing capacity of the gantry frames. At the same time, the base brace ensures the safe operation of the gantry frames in complex working environments by sharing the load, improving the resistance to lateral displacement, and providing additional support points.

[0020] In some embodiments, the gantry is connected to diagonal braces, which connect the gantry to the base support; the gantry, base support, and diagonal braces together form a triangular structure.

[0021] This technical solution involves installing diagonal braces between the gantry frame and the base support, forming a triangular structure. Utilizing the geometric properties of a triangle, the overall structural stability is increased, enabling the gantry frame to effectively resist bending and deformation. Simultaneously, the diagonal braces can distribute the vertical and horizontal loads applied to the gantry frame to different support points. Through the diagonal force transmission of the diagonal braces, the load can be effectively distributed to the foundation and surrounding structures, ensuring the safety and stability of the overall structure.

[0022] In some embodiments, four pulley blocks are provided, with the four pulley blocks corresponding to two gantry frames.

[0023] This technical solution designs four pulley blocks so that the steel lugs can be hoisted through the four pulley blocks. There are multiple connection points between the steel lugs and the four pulley blocks, and these multiple connection points together form a hoisting plane, thereby ensuring the stability of the steel lugs during hoisting.

[0024] In some embodiments, the four pulley blocks work independently to adjust the installation angle of the steel lugs on the pile foundation steel casing.

[0025] This technical solution sets up four pulley blocks that work independently, so that each of the four pulley blocks can pull the steel lugs vertically, thereby adjusting the installation angle of the steel lugs on the pile foundation steel casing.

[0026] In some embodiments, the fixed pulley is connected to a hook that is hooked onto the crossbeam of the gantry and can move along the crossbeam of the gantry.

[0027] This technical solution involves installing a hook on a fixed pulley, which is then hung on the crossbeam of the gantry frame to install the fixed pulley onto the gantry frame. By allowing the hook to move on the crossbeam of the gantry frame, the position of the fixed pulley on the gantry frame can be adjusted according to the size of the steel lug, the position of the pile foundation steel casing, and the installation position of the steel lug on the pile foundation steel casing, thereby facilitating the adjustment of the position of the steel lug and improving construction efficiency.

[0028] In some embodiments, the steel lug includes two connectors arranged radially opposite to each other along the steel casing of the pile foundation; the two connectors are detachably connected to each other.

[0029] This technical solution improves the construction efficiency of steel hanging ear installation by setting the steel hanging ear as two detachable connectors.

[0030] In some embodiments, the steel lugs are provided with pull rings for hanging the debris screen; there are two pull rings, and the two pull rings are correspondingly set with two connectors.

[0031] In some embodiments, the lifting hook and the pull ring are connected to each other by a cable.

[0032] This technical solution uses a cable to connect the lifting hook and the pull ring, making the connection between the lifting hook and the pull ring easier.

[0033] In some embodiments, the outer periphery of the steel casing of the pile foundation is provided with a stop to limit the position of the steel lugs in the axial direction of the steel casing of the pile foundation.

[0034] This technical solution involves setting blocks around the outer perimeter of the steel casing of the pile foundation to limit the position of the steel lugs on the steel casing and prevent the steel lugs from sliding down.

[0035] Based on the above technical solution, the aforementioned debris barrier installation device, by setting up a gantry and pulley system on a steel platform on the water, and using the pulley system to install the steel lugs onto the steel casing of the pile foundation, can reduce the swaying of the gantry and pulley system on the sea surface, thereby increasing the stability of the steel lugs during the installation process, thus increasing the installation efficiency of the steel lugs, reducing the risk of construction operations, and effectively solving the problem that the underwater installation accuracy of the steel lugs is difficult to control due to the large swaying of the ship caused by wind and waves.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] As attached Figures 1-5 As shown in an illustrative embodiment of the debris barrier installation device of this utility model, the debris barrier installation device includes a pile foundation steel casing 1, steel hanging lugs 2, a steel platform on water, a gantry frame 3, and a pulley block 4.

[0052] In the above-mentioned debris-blocking net installation device, such as Figure 1 As shown, the steel casing 1 of the pile foundation is set vertically in the seawater. The steel casing 1 of the pile foundation is a cylindrical structure, mainly used for the construction and protection of the pile foundation. The steel casing 1 of the pile foundation is usually made of steel and has strong load-bearing capacity and corrosion resistance.

[0053] As attached Figure 1 and Figure 5 As shown, in some embodiments, a stop block 11 is provided on the outer periphery of the pile foundation steel casing 1 to limit the position of the steel hanging lug 2 in the axial direction of the pile foundation steel casing 1 and prevent the steel hanging lug 2 from sliding down.

[0054] In the above-mentioned debris-blocking net installation device, such as Figure 1 and Figure 4 As shown, the steel hanging lug 2 is fitted around the outer periphery of the steel casing 1 of the pile foundation, and the steel hanging lug 2 is used to install the trash net.

[0055] In some embodiments, the steel lug 2 includes two connectors 22, which are arranged radially opposite to each other along the steel casing 1 of the pile foundation; the two connectors 22 are detachably connected to each other; by connecting the two connectors 22 to each other, the steel lug 2 is fixedly sleeved on the outer periphery of the steel casing 1 of the pile foundation, which facilitates the fixed connection between the steel lug 2 and the steel casing 1 of the pile foundation.

[0056] In other embodiments, the two connectors 22 are connected to each other by fasteners such as bolts or screws.

[0057] In some embodiments, the steel hanging lug 2 is provided with a pull ring 21, which is used to hang the debris barrier net; there are two pull rings 21, and the two pull rings 21 are correspondingly set with two connecting pieces 22. The edge of the debris barrier net is tied to the pull ring 21 to ensure that the debris barrier net is hung flat and firmly on the pull ring 21, so as to effectively intercept pollutants.

[0058] In the above-mentioned debris-blocking net installation device, the floating steel platform is used to install and support the gantry 3; the floating steel platform is a structure specially designed for construction, operation or as a temporary or permanent facility on the water surface. The floating steel platform is set around the pile foundation steel casing 1 to assemble the steel hanging lugs 2 and carry out subsequent installation operations.

[0059] In the above-mentioned debris-blocking net installation device, such as Figure 1 , Figure 2 and Figure 3 As shown, the gantry 3 is set on a steel platform above water and is used to install the pulley block 4.

[0060] In some embodiments, two gantry frames 3 are provided, and the two gantry frames 3 are arranged in parallel; the two gantry frames 3 are connected to each other by a base support 31, and the base support 31 is fixedly installed on the steel platform above water.

[0061] The bottom support 31 connects the two gantry frames 3 into an integral structure to improve the structural stability and load-bearing capacity of the gantry frames 3. At the same time, the bottom support 31 ensures that the gantry frames 3 can work safely in complex working environments by sharing the load, improving the resistance to lateral displacement, and providing additional support points.

[0062] In some embodiments, the gantry 3 is connected to a diagonal brace 32, which is used to connect the gantry 3 to the bottom support 31; the gantry 3, the bottom support 31 and the diagonal brace 32 together form a triangular structure.

[0063] A diagonal brace 32 is installed between the gantry frame 3 and the bottom support 31, forming a triangular structure between the gantry frame 3, the bottom support 31, and the diagonal brace 32. Utilizing the geometric properties of a triangle, the stability of the gantry frame 3 is increased, effectively resisting bending and deformation. At the same time, the diagonal brace 32 can distribute the vertical and horizontal loads applied to the gantry frame 3 to different support points. Through the diagonal force transmission of the diagonal brace 32, the load can be effectively distributed to the foundation and the surrounding structure, ensuring the safety and stability of the gantry frame 3.

[0064] In the above-mentioned debris-blocking net installation device, such as Figure 1 , Figure 2 and Figure 3 As shown, the pulley block 4 includes a fixed pulley 42, a movable pulley 43, and a rope 44; the fixed pulley 42 is installed on the gantry frame 3; the movable pulley 43 is located below the fixed pulley 42; the movable pulley 43 is connected to a lifting hook 45, which is connected to a pull ring 21; the first end of the rope 44 is fixedly connected to the movable pulley 43, and the second end of the rope 44 is arranged to pass through the fixed pulley 42 and the movable pulley 43 in sequence; pulling the second end of the rope 44 causes the rope 44 to drive the movable pulley 43 and the lifting hook 45 to move up and down, so that the steel hanging lug 2 is detached from the pile foundation steel casing 1 or fitted onto the pile foundation steel casing 1.

[0065] In some embodiments, the fixed pulley 42 is connected to a hook 41, which is hooked onto the crossbeam 33 of the gantry frame 3 and can move along the crossbeam 33 of the gantry frame 3.

[0066] By setting a hook 41 on the fixed pulley 42, the hook 41 is hung on the crossbeam 33 of the gantry 3, thereby installing the fixed pulley 42 on the gantry 3. By allowing the hook 41 to move on the crossbeam 33 of the gantry 3, the fixed pulley 42 can be adjusted on the crossbeam 33 according to the size of the steel lug 2, the position of the pile foundation steel casing 1, and the installation position of the steel lug 2 on the pile foundation steel casing 1, thereby facilitating the adjustment of the position of the steel lug 2 and improving construction efficiency.

[0067] In some embodiments, the lifting hook 45 and the pull ring 21 are connected to each other by a cable 5.

[0068] By setting a cable 5 on the pull ring 21, the end of the cable 5 away from the pull ring 21 is connected to the lifting hook 45, so as to realize the connection between the lifting hook 45 and the pull ring 21; when the pulley block 4 is set to four, each pull ring 21 is connected to two pulley blocks 4 through the cable 5, which facilitates the connection between the pull ring 21 and multiple pulley blocks 4.

[0069] In some embodiments, the four pulley blocks 4 work independently so that the four pulley blocks 4 can pull the steel hanging lugs 2 in the vertical direction respectively, thereby realizing the adjustment of the installation angle of the steel hanging lugs 2 on the pile foundation steel casing 1.

[0070] In some embodiments, four pulley blocks 4 are provided, and the four pulley blocks 4 are respectively arranged on two gantry frames 3.

[0071] By designing four pulley blocks 4, the steel lugs 2 are hoisted via these four pulley blocks 4. The four pulley blocks 4 are correspondingly installed on two gantry frames 3, and there are multiple connection points between the steel lugs 2 and the four pulley blocks 4. These connection points together form a hoisting plane, ensuring the stability of the steel lugs 2 during hoisting and ensuring that each pulley block 4 is evenly stressed. It should be noted that the four pulley blocks 4 are connected to two pull rings 21 to ensure even stress distribution on the steel lugs 2.

[0072] It should be noted that the number of gantry frames 3 installed can be adjusted according to the on-site construction environment, and the number and installation form of pulley blocks 4 can also be appropriately changed according to the construction conditions. For example, a more complex traveling device can be used to replace pulley blocks 4. The above modifications are simple modifications that can be understood by those skilled in the art, and will not be elaborated in the description of the embodiments.

[0073] The working principle of the above-mentioned debris barrier installation device is as follows: the worker pulls the second end of the rope 44, causing the rope 44 to drive the pulley 43 and the lifting hook 45 to move up and down. Under the action of the lifting hook 45, the steel hanging lug 2 also moves up and down on the pile foundation steel casing 1. After the steel hanging lug 2 is lowered to the target position, the diver securely fixes the steel hanging lug 2 to the pile foundation steel casing 1 underwater. Finally, the debris barrier is suspended between adjacent pile foundation steel casings 1.

[0074] In practical applications, construction workers first build a steel platform on the water, then install the gantry 3 on the steel platform, then use the pulley block 4 to install the steel hanging lug 2 on the pile foundation steel casing 1, and finally install the debris net on the steel hanging lug 2.

[0075] In the existing technology, when using a ship to transport the gantry 3, the ship is easily affected by wind and waves, which causes the gantry 3 to sway, making it difficult to install the steel lugs 2 underwater and making it difficult to control the installation accuracy.

[0076] In the aforementioned debris-blocking net installation device, the gantry 3 is installed on the pre-built floating steel platform, which provides a relatively stable working environment for the gantry 3, reducing the swaying during operation and increasing the stability of the gantry 3. A pulley block 4 is installed on the gantry 3 to hoist the steel lugs 2, which are then fitted onto the outer periphery of the pile foundation steel casing 1, facilitating the installation of the steel lugs 2. After the steel lugs 2 are fitted onto the pile foundation steel casing 1, the construction personnel then submerge in the water to fix the steel lugs 2 to the pile foundation steel casing 1.

[0077] The aforementioned debris-blocking net installation device can reduce diving operations, lower construction safety risks, and effectively solve the problem of difficulty in controlling the underwater installation accuracy of the steel lugs 2 due to the large swaying of ships caused by wind and waves.

[0078] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0079] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
