Description

Technical Field

[0001] The utility model relates to the technical field of fan installation, in particular to a lifting tool and lifting equipment. Background Art

[0002] In the field of wind power generation, the normal operation of wind turbine generators is crucial to the efficiency and reliability of the entire wind power generation system. For the Goldwind S48-750 wind turbine, the inspection and maintenance of the high-speed brake is a key part of ensuring the safe operation of the wind turbine.

[0003] However, due to the heavy weight of high-speed brake components, usually between 300 and 400 kilograms, and the relatively small working space, traditional inspection and maintenance methods mainly rely on manpower for disassembly and assembly operations.

[0004] Without specialized installation tools, manually lifting and installing high-speed gate components presents numerous problems. First, the heavy weight of the components and the limited operating space make installation extremely difficult, making it difficult to ensure the components are positioned smoothly and accurately. Poor control during the installation process can easily lead to improper installation of the high-speed gate, impacting the normal operation of the equipment. Second, manual lifting of heavy objects carries significant safety risks, which can easily cause equipment and personnel to be injured, threatening the safety of operators. Furthermore, manual operation is inefficient and time-consuming, further increasing the difficulty and cost of maintenance work.

[0005] Furthermore, many wind turbine installation and operation locations may be located in remote areas such as mountainous areas or islands, where transportation is inconvenient and the environment is complex, further increasing the difficulty of inspecting and maintaining high-speed gates. In these environments, installation tooling must not only be efficient and safe but also portable and user-friendly. Therefore, existing manual installation methods clearly cannot meet these requirements.

[0006] The above information disclosed in the background of this application is only used to understand the background of the concept of this application, and does not indicate or suggest that it contains information of the prior art. Utility Model Content

[0007] Based on this, it is necessary to provide a lifting tool and lifting equipment to address the above problems.

[0008] A lifting tool, comprising:

[0009] a first bracket, the first bracket comprising a first vertical pole and a cross bar connected to the first vertical pole, the cross bar being arranged at an angle to the first vertical pole, the cross bar being used to mount a lifting device, the lifting device being used to lift the fan high-speed gate;

[0010] The second bracket includes a second vertical pole and a support base connected to the bottom end of the second vertical pole, the support base is used to be connected to the fan base, and the top end of the second vertical pole is detachably connected to the bottom end of the first vertical pole.

[0011] The aforementioned lifting fixture achieves at least the following beneficial effects: Its design makes installation extremely simple. Simply secure the support base of the second bracket to the wind turbine base, then connect the bottom end of the first upright of the first bracket to the top end of the second bracket to complete the entire lifting fixture. This simple installation method significantly reduces installation time and labor costs. To lift the wind turbine high-speed gate, simply attach a lifting device, such as an electric hoist or hand chain hoist, to the crossbar of the first bracket. The lifting device can then be used to lift the wind turbine high-speed gate to the designated location for installation or removal. The relatively high height of the first bracket ensures that the crossbar is mounted high, providing ample lifting space, thereby improving lifting efficiency and operational flexibility. Furthermore, since the lifting device is mounted high on the crossbar, stability and safety are ensured during lifting, reducing the risk of equipment and personnel damage due to operational errors. Furthermore, the first and second brackets are detachably connected, allowing them to be disassembled when not in use for easy storage and portability. This feature is particularly suitable for situations where wind turbines are installed and used in remote areas such as mountainous areas or islands, solving the problem of the inconvenience of carrying traditional lifting tools. By using this special lifting tool, the stability and accuracy of the wind turbine high-speed gate during installation can be ensured, avoiding the problem of inadequate installation due to manual operation, improving the overall installation process, and reducing the need for manual lifting of heavy objects, reducing the labor intensity of operators, reducing the risk of injuries caused by lifting heavy objects, and improving the safety of the working environment. In short, this lifting tool not only simplifies the installation and disassembly process of the wind turbine high-speed gate, improves operational efficiency and safety, but also has good portability and storage, and is suitable for various complex and remote wind turbine installation environments, significantly improving the overall level of wind turbine maintenance work.

[0012] In one embodiment, a limiting post is provided at either the bottom end of the first upright or the top end of the second upright, and a limiting hole is provided at the other of the two. The limiting post is removably inserted into the limiting hole to secure the first and second uprights. The design of the limiting post and limiting hole ensures a more stable connection between the first and second uprights. Once the limiting post is inserted into the limiting hole, it can effectively prevent the uprights from loosening or shifting during use, thereby ensuring the overall stability and safety of the lifting fixture. The detachable design of the limiting post and limiting hole makes connecting and disassembling the first and second uprights very simple. The operator only needs to insert the limiting post into the limiting hole to complete installation, and to remove it simply by pulling out the limiting post. The entire process does not require complex tools or operations, greatly improving the efficiency of installation and disassembly. Because the first and second uprights can be detachably connected via the limiting post and limiting hole, they can be easily separated when not in use, making them easier to carry and store. This design is particularly suitable for wind turbine installation and maintenance scenarios in remote areas such as mountainous areas or islands, solving the problem of the inconvenience of carrying traditional lifting tools.

[0013] In one embodiment, the outer circumference of the limiting column and the inner circumference of the limiting hole are both provided with threads, and the limiting column is inserted into the limiting hole in a threaded connection manner to achieve the fixation of the first upright and the second upright. Compared with a simple plug-in connection, the threaded connection has a better anti-slip function. Even if it is subjected to vibration or impact during the lifting process, the threaded connection can ensure that the first upright and the second upright will not be accidentally separated, thereby providing a higher level of safety. Although the threaded connection is slightly more complicated than the simple plug-in connection, the actual operation is still very convenient. The operator only needs to rotate the limiting column to complete the connection or disassembly, without the need for additional tools or complicated operating steps. This design not only ensures a stable connection, but also takes into account the convenience of assembly and disassembly. The operator can quickly complete the assembly and disassembly, reducing the time required for installation and disassembly, thereby focusing on the lifting and installation of the wind turbine high-speed gate and improving overall work efficiency.

[0014] In one embodiment, the outer circumference of the first vertical pole is provided with a first supporting protrusion, and the outer circumference of the second vertical pole is provided with a second supporting protrusion. When the first vertical pole is connected to the second vertical pole, the first supporting protrusion and the second supporting protrusion abut against each other. The mutual abutment of the first supporting protrusion and the second supporting protrusion increases the contact area and supporting force between the two vertical poles, making the connection between the vertical poles tighter and increasing the strength of the connection part. Even when subjected to large external forces and heavy loads during the lifting process, the two vertical poles can remain firmly connected and are not prone to loosening or displacement, ensuring the safety and reliability of the lifting process. The mutual abutment of the supporting protrusions can disperse the stress at the connection of the vertical poles to a larger contact area, thereby reducing the situation of single-point force. This design can effectively reduce the damage to the connection of the vertical poles caused by stress concentration and extend the service life of the lifting tooling.

[0015] In one embodiment, the first support protrusion extends in a ring shape along the circumference of the first vertical pole, and the second support protrusion extends in a ring shape along the circumference of the second vertical pole. The ring-shaped support protrusion provides 360-degree all-round support, so that the contact between the two vertical poles at the connection is more uniform and tight. Compared with point-shaped or line-shaped support, the ring-shaped support can more effectively disperse the force and provide stronger stability and supporting force. The ring-shaped support protrusion increases the contact area between the two vertical poles, thereby improving the strength and stability of the connection. Even under large loads, the two vertical poles can maintain a firm connection, ensuring the safety and reliability of the lifting process. The ring-shaped support protrusion can effectively disperse the stress at the connection, reduce the damage to the vertical pole connection caused by stress concentration, and thus extend the service life of the lifting tooling. The uniform force characteristic of the ring-shaped design makes the connection more durable and adaptable to long-term and high-intensity use requirements.

[0016] In one embodiment, the limiting column is protruded from the bottom end of the first vertical pole, the limiting hole is provided at the top end of the second vertical pole, and the second supporting protrusion is provided at the edge of the limiting hole.

[0017] In one embodiment, the limiting hole is provided at the bottom end of the first vertical pole, the first supporting protrusion is provided at the edge of the limiting hole, and the limiting column is provided at the top end of the second vertical pole.

[0018] In one embodiment, the first bracket further includes a reinforcing rod, one end of which is connected to the first vertical rod and arranged at an angle to the first vertical rod, and the other end of which is connected to the crossbar and arranged at an angle to the crossbar. The reinforcing rod is located between the first vertical rod and the crossbar to support the crossbar. The reinforcing rod provides additional support and fixation, further stabilizing the connection between the first vertical rod and the crossbar. Since the reinforcing rod is arranged at an angle to the first vertical rod and the crossbar, respectively, it effectively distributes and transmits force, improving the stability and seismic resistance of the overall structure. The provision of the reinforcing rod increases the load-bearing capacity of the bracket. By providing an additional support point between the first vertical rod and the crossbar, the reinforcing rod effectively shares the load on the crossbar, effectively preventing the crossbar from bending and deforming under load. By providing additional support, it prevents the crossbar from deforming due to localized excessive stress, which could lead to structural instability and damage. When subjected to heavy loads and external forces, the reinforcing rod provides additional support and protection, preventing the bracket from tipping over or collapsing, thereby ensuring the safety and reliability of the lifting process.

[0019] In one embodiment, the crossbar is provided with a lifting ring for hanging the lifting device. The lifting ring provides a dedicated fixed point for hanging the lifting device, making the hanging operation more convenient and quick. The operator simply hangs the lifting device's hook or sling on the lifting ring to complete the hanging operation, reducing the number of steps and improving work efficiency. The lifting ring can be made of high-strength material and is firmly connected to the crossbar, capable of bearing large loads. It should be noted that the number and position of the lifting rings can be flexibly designed to adjust the number of lifting rings according to actual needs, and the lifting rings can be placed at different positions on the crossbar to accommodate various hanging requirements. Whether hanging at a single point or multiple points, the lifting rings provide reliable support and adapt to different working environments and conditions. It is understood that the lifting rings can be used not only for hanging the lifting device, but also for hanging other equipment or tools, increasing the versatility and practicality of the bracket. Whether during installation, maintenance, or other operations, the lifting rings provide convenient hanging support.

[0020] In one embodiment, the cross bar is connected to the top end of the first vertical bar.

[0021] In one embodiment, the first vertical rod and the horizontal rod are arranged perpendicular to each other.

[0022] In one embodiment, the first vertical pole, the second vertical pole and the cross pole are all hollow poles. The design of the hollow pole can significantly reduce the weight of the entire lifting tooling, making the bracket lighter. Reducing weight not only facilitates transportation and installation, but also reduces the load on the foundation and supporting structure. Since the hollow pole has a hollow structure inside, less material is used compared to a solid pole, saving manufacturing costs. This design optimizes the use of materials and improves economic benefits while ensuring strength and stability. When appropriate, the internal space of the hollow pole can also be used to arrange cables, pipes and other facilities, providing convenient installation conditions. This design enables the bracket to not only have a mechanical support function, but also integrate other functions, thereby improving the integration and practicality of the system.

[0023] In one embodiment, the lifting fixture further comprises a support rib, one end of which is connected to the top surface of the support base and the other end of which is connected to the outer circumference of the bottom end of the second upright. By connecting one end of the support rib to the top surface of the support base and the other end to the outer circumference of the bottom end of the second upright, a triangular support structure is formed, improving the stability and anti-overturning resistance of the overall structure. The design of the support ribs disperses the load, reducing the burden of single-point stress. The support ribs transfer part of the load to the support base and the second upright, reducing stress concentration on a single member and improving the load-bearing capacity and service life of the lifting fixture. The provision of the support ribs effectively prevents the support base and the second upright from deforming and tilting when subjected to stress. The connection of the support ribs makes the structure more stable, maintaining balance and stability during lifting, and preventing accidental tilting and deformation. The design of the support ribs enhances the safety of the lifting fixture. By providing additional support and fixation, the support ribs effectively prevent the lifting fixture from accidentally sliding or overturning during use, improving operational safety and reliability.

[0024] In one embodiment, the lifting fixture further comprises a fastener. The support base is provided with a mounting hole for the fastener to pass through, allowing the fastener to threadably connect with a threaded hole in the fan base to secure the support base to the fan base. By providing the mounting hole in the support base and using the fastener to threadably connect with the threaded hole in the fan base, the stability of the fixation between the support base and the fan base can be effectively improved. The threaded connection of the fastener provides a more secure fixation, preventing loosening or falling off during lifting. The design of the fastener and mounting hole simplifies the installation process of the support base and the fan base. The operator simply passes the fastener through the mounting hole and threadably connects it with the threaded hole in the fan base to complete the fixation, reducing installation time and steps and improving work efficiency. The design of the fastener makes the lifting fixture highly reusable. The operator can install and remove the support base multiple times as needed. The durability and reliability of the fastener ensure the long-term use of the lifting fixture, reducing equipment replacement and procurement costs.

[0025] The present application also provides a lifting device, which includes a lifting device and a lifting tool as described in any of the above embodiments.

[0026] Because the lifting device includes the lifting fixture described in any of the above embodiments, it also provides at least the following beneficial effects: The entire lifting fixture can be assembled by simply securing the support base of the second bracket to the wind turbine base and then connecting the bottom end of the first upright of the first bracket to the top end of the second bracket. This simple installation method significantly reduces installation time and labor costs. When lifting the wind turbine high-speed gate, a lifting device such as an electric hoist or a hand chain hoist is simply attached to the crossbar of the first bracket. The lifting device can then be used to lift the wind turbine high-speed gate to a designated location for installation or removal. The relatively high height of the first bracket ensures that the crossbar is mounted high, providing ample lifting space, thereby improving lifting efficiency and operational flexibility. Furthermore, since the lifting device is mounted high on the crossbar, stability and safety are ensured during lifting, reducing the risk of equipment and personnel damage due to operational errors. Furthermore, the first and second brackets are detachably connected, allowing them to be disassembled when not in use for easy storage and portability. This feature is particularly suitable for situations where wind turbines are installed and used in remote areas such as mountainous areas or islands, solving the problem of the inconvenience of carrying traditional lifting tools. By using this special lifting tool, the stability and accuracy of the wind turbine high-speed gate during installation can be ensured, avoiding the problem of inadequate installation due to manual operation, improving the overall installation process, and reducing the need for manual lifting of heavy objects, reducing the labor intensity of operators, reducing the risk of injuries caused by lifting heavy objects, and improving the safety of the working environment. In short, this lifting tool not only simplifies the installation and disassembly process of the wind turbine high-speed gate, improves operational efficiency and safety, but also has good portability and storage, and is suitable for various complex and remote wind turbine installation environments, significantly improving the overall level of wind turbine maintenance work.

DETAILED DESCRIPTION

[0035] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In some embodiments, the present application provides a lifting tool 11, which includes a first bracket 100 and a second bracket 200. The first bracket 100 includes a first vertical pole 110 and a cross bar 120 connected to the first vertical pole 110. The cross bar 120 is arranged at an angle to the first vertical pole 110. The cross bar 120 is used to install a lifting device 12, and the lifting device 12 is used to lift the wind turbine high-speed gate; the second bracket 200 includes a second vertical pole 210 and a support base 220 connected to the bottom end of the second vertical pole 210. The support base 220 is used to connect to the wind turbine base, and the top end of the second vertical pole 210 is detachably connected to the bottom end of the first vertical pole 110.

[0037] The lifting fixture 11 described above can achieve at least the following beneficial effects: The design of the lifting fixture 11 makes the installation process extremely simple. Simply secure the support base 220 of the second bracket 200 to the wind turbine base, then connect the bottom end of the first upright 110 of the first bracket 100 to the top end of the second bracket 200 to complete the assembly of the lifting fixture 11. This simple installation method significantly reduces installation time and labor costs. When lifting the wind turbine high-speed gate, simply attach a lifting device 12, such as an electric hoist or a hand chain hoist, to the crossbar 120 of the first bracket 100. The lifting device 12 can then be used to lift the wind turbine high-speed gate to the designated location for installation or removal. The relatively high height of the first bracket 100 ensures that the crossbar 120 is installed at a high position, providing ample lifting space, thereby improving lifting efficiency and operational flexibility. Furthermore, since the lifting device 12 is mounted high on the crossbar 120, stability and safety are ensured during the lifting process, reducing the risk of equipment and personnel damage due to operational errors. In addition, the first bracket 100 and the second bracket 200 are detachably connected, and the two can be disassembled when not in use, making them easy to store and carry. This feature is particularly suitable for situations where wind turbine installation and use scenarios are located in remote areas such as mountainous areas or islands, and solves the problem of inconvenience in carrying traditional lifting tools. By using this special lifting tool 11, the stability and accuracy of the wind turbine high-speed gate during the installation process can be ensured, and the problem of inadequate installation due to manual operation can be avoided, thereby improving the overall installation process level. It can also reduce the need for manual lifting of heavy objects, reduce the labor intensity of operators, reduce the risk of injuries caused by lifting heavy objects, and improve the safety of the working environment. In short, the lifting tool 11 not only simplifies the installation and disassembly process of the wind turbine high-speed gate, improves operational efficiency and safety, but also has good portability and storage, and is suitable for various complex and remote wind turbine installation environments, significantly improving the overall level of wind turbine maintenance work.

[0038] Specifically, if Figure 4 and Figure 5As shown, in some embodiments, either the bottom end of the first upright 110 or the top end of the second upright 210 is provided with a limiting column 111, and the other of the bottom end of the first upright 110 and the top end of the second upright 210 is provided with a limiting hole 212, and the limiting column 111 is detachably inserted into the limiting hole 212 to achieve the fixation of the first upright 110 and the second upright 210. The design of the limiting column 111 and the limiting hole 212 ensures that the connection between the first upright 110 and the second upright 210 is more stable. After the limiting column 111 is inserted into the limiting hole 212, it can effectively prevent the uprights from loosening or shifting during use, thereby ensuring the overall stability and safety of the lifting tool 11. The detachable design of the limiting column 111 and the limiting hole 212 makes the connection and disassembly of the first upright 110 and the second upright 210 very simple. Operators only need to insert the limiting post 111 into the limiting hole 212 to complete installation. For removal, they simply need to pull out the limiting post 111. The entire process requires no complex tools or operations, greatly improving installation and removal efficiency. Because the first and second vertical poles 110 and 210 can be detached and connected via the limiting post 111 and limiting hole 212, they can be easily separated when not in use, making them easier to carry and store. This design is particularly suitable for wind turbine installation and maintenance in remote areas such as mountainous areas or islands, solving the problem of the inconvenience of carrying traditional lifting tools.

[0039] More specifically, in some embodiments, the outer circumference of the limiting post 111 and the inner circumference of the limiting hole 212 are both provided with threads, and the limiting post 111 is inserted into the limiting hole 212 in a threaded connection to achieve the fixation of the first upright 110 and the second upright 210. Compared with a simple plug-in connection, a threaded connection has a better anti-slip function. Even if subjected to vibration or impact during the lifting process, the threaded connection can ensure that the first upright 110 and the second upright 210 will not accidentally separate, thereby providing a higher level of safety. Although the threaded connection is slightly more complicated than a simple plug-in connection, the actual operation is still very convenient. The operator only needs to rotate the limiting post 111 to complete the connection or disassembly, without the need for additional tools or complicated operating steps. This design not only ensures a stable connection, but also takes into account the convenience of assembly and disassembly. The operator can quickly complete assembly and disassembly, reducing the time required for installation and disassembly, thereby focusing on the lifting and installation of the wind turbine high-speed gate, improving overall work efficiency.

[0040] See also Figure 3 、 Figure 4 and Figure 5In some embodiments, the outer circumference of the first vertical pole 110 is provided with a first supporting protrusion 112, and the outer circumference of the second vertical pole 210 is provided with a second supporting protrusion 211. When the first vertical pole 110 is connected to the second vertical pole 210, the first supporting protrusion 112 and the second supporting protrusion 211 abut against each other. The mutual abutment of the first supporting protrusion 112 and the second supporting protrusion 211 increases the contact area and supporting force between the two vertical poles, making the connection between the vertical poles tighter and increasing the strength of the connection part. Even when subjected to large external forces and heavy loads during the lifting process, the two vertical poles can remain firmly connected and are not prone to loosening or displacement, ensuring the safety and reliability of the lifting process. The mutual abutment of the supporting protrusions can disperse the stress at the vertical pole connection to a larger contact area, thereby reducing the single-point force situation. This design can effectively reduce the damage to the vertical pole connection caused by stress concentration and extend the service life of the lifting tool 11.

[0041] Specifically, if Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the first support protrusion 112 extends in a ring shape along the circumference of the first vertical pole 110, and the second support protrusion 211 extends in a ring shape along the circumference of the second vertical pole 210. The annular support protrusion provides 360-degree all-round support, so that the contact between the two vertical poles at the connection is more uniform and tight. Compared with point or line support, the annular support can more effectively disperse the force and provide stronger stability and support force. The annular support protrusion increases the contact area between the two vertical poles, thereby improving the strength and stability of the connection. Even under large loads, the two vertical poles can remain firmly connected to ensure the safety and reliability of the lifting process. The annular support protrusion can effectively disperse the stress at the connection, reduce the damage to the vertical pole connection caused by stress concentration, and thus extend the service life of the lifting tooling 11. The uniform force characteristics of the annular design make the connection more durable and adaptable to long-term and high-intensity use requirements.

[0042] For example, Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the bottom end of the first vertical rod 110 is provided with the limiting column 111, the top end of the second vertical rod 210 is provided with the limiting hole 212, and the second supporting protrusion 211 is provided at the edge of the limiting hole 212.

[0043] For example, in some other embodiments, the bottom end of the first vertical pole 110 is provided with the limiting hole 212, the first supporting protrusion 112 is provided at the edge of the limiting hole 212, and the top end of the second vertical pole 210 is protruded with the limiting column 111.

[0044] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments, the first bracket 100 further includes a reinforcing rod 130, one end of the reinforcing rod 130 is connected to the first vertical pole 110 and is set at an angle to the first vertical pole 110, the other end of the reinforcing rod 130 is connected to the cross bar 120 and is set at an angle to the cross bar 120, and the reinforcing rod 130 is located between the first vertical pole 110 and the cross bar 120 to support the cross bar 120. The reinforcing rod 130 provides additional support and fixation, making the connection between the first vertical pole 110 and the cross bar 120 more stable. Since the reinforcing rod 130 is set at an angle to the first vertical pole 110 and the cross bar 120 respectively, it can effectively disperse and transmit the force, thereby improving the stability and seismic performance of the overall structure. The provision of the reinforcing rod 130 increases the bearing capacity of the bracket. By providing an additional support point between the first vertical pole 110 and the crossbar 120, the reinforcement rod 130 effectively shares the load on the crossbar 120, effectively preventing the crossbar 120 from bending and deforming under load. By providing additional support, the crossbar 120 is protected from structural instability and damage caused by localized excessive stress and deformation. When subjected to large loads and external forces, the reinforcement rod 130 provides additional support and protection, preventing the bracket from tipping over or collapsing, ensuring the safety and reliability of the lifting process.

[0045] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4In some embodiments, the crossbar 120 is provided with a lifting ring 140, and the lifting ring 140 is used for hanging the lifting device 12. The provision of the lifting ring 140 provides a fixed point specifically for hanging the lifting device 12, making the hanging operation more convenient and quick. The operator only needs to hang the hook or sling of the lifting device 12 on the lifting ring 140 to complete the hanging operation, which reduces the number of operating steps and improves work efficiency. The lifting ring 140 can be made of high-strength material and is firmly connected to the crossbar 120, capable of bearing a large load. It should be noted that the number and position of the lifting ring 140 can be flexibly designed. The number of the lifting ring 140 can be adjusted according to actual needs, and the lifting ring 140 can also be set at different positions on the crossbar 120 to adapt to various different hanging requirements. Whether it is single-point hanging or multi-point hanging, the lifting ring 140 can provide reliable support and adapt to different working environments and working conditions. It is understood that the lifting ring 140 can be used not only for hanging the lifting device 12, but also for hanging other equipment or tools, thereby increasing the versatility and practicality of the bracket. Whether in installation, maintenance or other operations, the lifting ring 140 can provide convenient hanging support.

[0046] Furthermore, in some embodiments, the cross bar 120 is connected to the top end of the first vertical bar 110 .

[0047] Furthermore, in some embodiments, the first vertical rod 110 and the horizontal rod 120 are arranged perpendicular to each other.

[0048] Furthermore, in some embodiments, the first vertical pole 110, the second vertical pole 210, the reinforcing rod 130 and the cross rod 120 are all hollow rods. The design of the hollow rod can significantly reduce the weight of the entire lifting tooling 11, making the bracket lighter. Reducing weight not only facilitates transportation and installation, but also reduces the load on the foundation and supporting structure. Since the hollow rod has a hollow structure inside, less material is used than a solid rod, saving manufacturing costs. This design optimizes the use of materials and improves economic benefits while ensuring strength and stability. When appropriate, the internal space of the hollow rod can also be used to arrange cables, pipes and other facilities, providing convenient installation conditions. This design enables the bracket to not only have a mechanical support function, but also integrate other functions, thereby improving the integration and practicality of the system.

[0049] See also Figure 5In some embodiments, the lifting fixture 11 further includes a support rib 230, one end of which is connected to the top surface of the support base 220, and the other end of which is connected to the outer circumference of the bottom end of the second upright 210. By connecting one end of the support rib 230 to the top surface of the support base 220 and the other end to the outer circumference of the bottom end of the second upright 210, a triangular support structure is formed, which improves the stability and anti-overturning ability of the overall structure. The design of the support rib 230 can disperse the load and reduce the burden of single-point stress. The support rib 230 transfers part of the load to the support base 220 and the second upright 210, reducing stress concentration in a single member and improving the load-bearing capacity and service life of the lifting fixture 11. The provision of the support rib 230 effectively prevents the support base 220 and the second upright 210 from deforming and tilting when subjected to stress. The connection of the support rib 230 makes the structure more stable, maintaining balance and stability during lifting, and preventing accidental tilting and deformation. The design of the support ribs 230 increases the safety of the lifting tool 11. By providing additional support and fixation, the support ribs 230 can effectively prevent the lifting tool 11 from accidentally sliding or overturning during use, thereby improving the safety and reliability of the operation.

[0050] Furthermore, in some embodiments, the lifting fixture 11 also includes a fastener, and a mounting hole 221 is provided on the support base 220. The mounting hole 221 is used for the fastener to pass through, so that the fastener can be threadedly connected to the threaded hole on the fan base to achieve the fixation of the support base 220 and the fan base. By providing the mounting hole 221 on the support base 220 and using the fastener to thread the threaded hole on the fan base, the fixation stability of the support base 220 and the fan base can be effectively improved. The threaded connection method of the fastener makes the fixation more secure and prevents loosening or falling off during the lifting process. The design of the fastener and the mounting hole 221 simplifies the installation process of the support base 220 and the fan base. The operator only needs to pass the fastener through the mounting hole 221 and thread it with the threaded hole on the fan base to complete the fixation, which reduces the installation time and steps and improves work efficiency. The design of the fastener makes the lifting fixture 11 highly reusable. The operator can install and remove the support seat 220 multiple times as needed. The durability and reliability of the fasteners ensure the long-term use of the lifting tool 11 and reduce the replacement and procurement costs of the equipment.

[0051] In addition, if Figure 1 As shown, the present application also provides a lifting device 10, which includes a lifting device 12 and a lifting tool 11 as described in any of the above embodiments.

[0052] Because the lifting device 10 includes the lifting fixture 11 described in any of the above embodiments, it also provides at least the following beneficial effects: The entire lifting fixture 11 can be assembled by simply securing the support base 220 of the second bracket 200 to the wind turbine base and then connecting the bottom end of the first upright 110 of the first bracket 100 to the top end of the second bracket 200. This simple installation method significantly reduces installation time and labor costs. When lifting the wind turbine high-speed gate, simply attach a lifting device 12, such as an electric hoist or a hand chain hoist, to the crossbar 120 of the first bracket 100. The lifting device 12 can then be used to lift the wind turbine high-speed gate to a designated location for installation or removal. The relatively high height of the first bracket 100 ensures that the crossbar 120 is mounted high, providing ample lifting space, thereby improving lifting efficiency and operational flexibility. Furthermore, since the lifting device 12 is mounted high on the crossbar 120, stability and safety are ensured during the lifting process, reducing the risk of equipment and personnel damage due to operational errors. In addition, the first bracket 100 and the second bracket 200 are detachably connected, and the two can be disassembled when not in use, making them easy to store and carry. This feature is particularly suitable for situations where wind turbine installation and use scenarios are located in remote areas such as mountainous areas or islands, and solves the problem of inconvenience in carrying traditional lifting tools. By using this special lifting tool 11, the stability and accuracy of the wind turbine high-speed gate during the installation process can be ensured, and the problem of inadequate installation due to manual operation can be avoided, thereby improving the overall installation process level. It can also reduce the need for manual lifting of heavy objects, reduce the labor intensity of operators, reduce the risk of injuries caused by lifting heavy objects, and improve the safety of the working environment. In short, the lifting tool 11 not only simplifies the installation and disassembly process of the wind turbine high-speed gate, improves operational efficiency and safety, but also has good portability and storage, and is suitable for various complex and remote wind turbine installation environments, significantly improving the overall level of wind turbine maintenance work.
