Description

Technical Field

[0001] This utility model relates to the field of construction technology for the installation of large-megawatt wind turbine towers and the tightening of bolt torque in deep-sea areas, and in particular to a prefabricated auxiliary tooling for wind turbine tower installation. Background Technology

[0002] Manually using heavy-duty hydraulic wrenches to tighten bolts on offshore wind turbine towers is a common practice in offshore wind power construction. However, due to the rapid development of offshore wind power in China, the capacity of individual offshore wind turbines is increasing from 3.XMW to 20.XMW. Consequently, the towers are becoming larger, and the connecting bolts between the towers are also becoming larger and heavier. This leads to a significant decrease in construction efficiency. Therefore, auxiliary bolt tightening tools are essential to improve the efficiency of tightening bolts on offshore wind turbine towers.

[0003] As the capacity of offshore wind turbine units increases, heavy-duty hydraulic wrenches become increasingly heavy. A typical 15-type heavy-duty wrench weighs about 60 kilograms, and a 20-type heavy-duty wrench weighs about 65 kilograms. The traditional method of manually carrying heavy-duty hydraulic wrenches to tighten tower bolts is physically demanding for construction workers, making it impossible to carry out continuous construction for extended periods and reducing construction efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a prefabricated auxiliary tooling for wind turbine tower installation that is reasonably designed, easy to use, and saves a lot of physical labor for construction workers, in order to overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assembly-type auxiliary tooling for wind turbine tower installation is characterized in that the tooling is installed on a tower connection platform and includes a heavy-duty wrench for installing the wind turbine tower, a heavy-duty wrench support frame for reducing the physical exertion of personnel, and a vehicle body that moves circumferentially along the wind turbine tower flange. The heavy-duty wrench is mounted on the vehicle body via the heavy-duty wrench support frame. The heavy-duty wrench support frame includes a left upright, a right upright, and a gantry mounted on the top of the two uprights. A sliding assembly for moving the heavy-duty wrench is installed on the gantry, and a balancer connected to the heavy-duty wrench is installed on the sliding assembly. A height adjustment mechanism for adjusting the height of the gantry is provided on both the left and right uprights.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the vehicle body includes a seat and nylon wheels installed at the bottom of the seat, and the left and right uprights are installed on the top of the seat.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the height adjustment mechanism includes a lifting sleeve sleeved on the left and right uprights, an adjusting bolt installed on the inner wall of the lifting sleeve, and a number of insertion holes that cooperate with the adjusting bolts are provided on the left and right uprights, and the number of insertion holes are arranged vertically.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the sliding component includes a C-shaped rail horizontally mounted on the gantry and a trolley that slides with the C-shaped rail. The trolley is suspended on the C-shaped rail and is provided with a connecting piece that connects to the balancer.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: two nylon wheels are provided at the bottom of the seat on the same side, and the distance between the two nylon wheels is the width of the wind turbine mounting tower flange.

[0011] Compared with existing technologies, this utility model adopts a modular assembly approach, connecting all parts of the vehicle body, gantry, and heavy-duty wrench support frame for greater convenience and ease of transport to various construction sites. The gantry uses a plug-in connection and is designed with positioning and adjustment bolts, allowing for height adjustment to suit individual workers and providing greater comfort and convenience. A sliding component allows the heavy-duty wrench to be freely adjusted within the track range, broadening its applicability. With a balancer and nylon wheels at the bottom, workers can more easily move and lift the heavy-duty hydraulic wrench, reducing physical exertion and increasing efficiency. Furthermore, workers can perform bolt tightening tasks independently without assistance. Attached Figure Description

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.

[0018] Reference Figure 1-3 An assembly-type auxiliary tooling for wind turbine tower installation includes a heavy-duty wrench for installing the wind turbine tower, a heavy-duty wrench support frame to reduce the physical exertion of personnel, and a vehicle body that moves circumferentially along the wind turbine tower flange. The heavy-duty wrench is mounted on the vehicle body via the heavy-duty wrench support frame. The heavy-duty wrench support frame includes a left upright 2, a right upright, and a gantry 5 mounted on the top of the two uprights. A sliding assembly for moving the heavy-duty wrench is mounted on the gantry 5, and a balancer connected to the heavy-duty wrench is mounted on the sliding assembly. A height adjustment mechanism for adjusting the height of the gantry is provided on both the left upright 2 and the right upright.

[0019] The vehicle body includes a seat 8 and nylon wheels 1 installed at the bottom of the seat 8, and the left upright 2 and right upright are installed at the top of the seat 8.

[0020] The height adjustment mechanism includes a lifting sleeve 4 fitted onto the left upright 2 and the right upright. An adjusting bolt 3 is installed on the inner wall of the lifting sleeve 4. Several insertion holes that cooperate with the adjusting bolt 2 are provided on both the left upright 2 and the right upright. The insertion holes are arranged vertically.

[0021] The sliding assembly includes a C-shaped rail 6 horizontally mounted on the gantry and a trolley 7 that slides with the C-shaped rail 6. The trolley 7 is suspended on the C-shaped rail 6 and has a connecting piece that connects to the balancer.

[0022] Two nylon wheels 8 are provided at the bottom of the seat 8 on the same side, and the distance between the two nylon wheels is the width of the wind turbine mounting tower flange.

[0023] The working process of the prefabricated auxiliary tooling for wind turbine tower installation described in this utility model is as follows: Construction personnel pre-position themselves on the tower connection platform and pre-assemble the auxiliary tooling. After the tower assembly is completed, the construction personnel place the pre-assembled auxiliary tooling on the flange platform and inspect the nylon wheels on the auxiliary tooling to ensure a secure connection. A balancer is installed on a C-shaped rail trolley, and a heavy-duty wrench is connected to the balancer. The height of the upright is adjusted using adjusting bolts. After adjusting the auxiliary tooling to a suitable construction height, the adjusting bolts are tightened to secure it. During use, when construction personnel lift the heavy-duty wrench, the upper balancer relieves the force on the wrench, reducing physical exertion. After the construction personnel have tightened the bolts around the wrench, they push the tooling, using the bottom nylon wheels to control its horizontal movement on the flange until all flange bolts are tightened. After completion, the tooling is removed.

[0024] Using the auxiliary tooling described in this utility model to replace manual lifting during construction can significantly reduce the physical exertion of construction personnel in tightening the high-strength bolts of the tower. This results in less personnel input, more convenient construction, and higher construction efficiency. It can also significantly shorten the single-unit operation time of the offshore wind turbine installation platform vessel, thereby reducing a large amount of vessel, equipment, and personnel costs.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
