Description

Technical Field

[0001] This invention relates to the field of wind turbine foundation technology, and more specifically, to an anchor bolt cage installation platform. Background Technology

[0002] The wind turbine foundation anchor structure includes an upper anchor plate, a lower anchor plate, and multiple anchor bolts. The upper and lower anchor plates are positioned opposite each other with a certain height difference. Multiple anchor bolts are inserted between the upper and lower anchor plates to form a circular anchor cage. Due to the technological advancements in wind turbine generators, smaller units are gradually replacing larger ones, resulting in increasingly taller wind turbine foundation anchor structures.

[0003] Currently, when installing anchor bolts, workers need to wear safety belts connected to the crane hook by a safety rope and stand on the upper anchor plate to work. This not only poses a high safety risk of working at height, but also makes construction difficult and reduces efficiency due to the narrow space of the upper anchor plate. Summary of the Invention

[0004] The purpose of this invention is to provide an anchor bolt cage installation platform to improve the technical problems of high safety risks and low efficiency in the installation of anchor bolts in the prior art.

[0013] The column has a first fixing hole and a second fixing hole. A platform pin passes through the first fixing hole to support the working platform. A fixing ring pin passes through the second fixing hole to support the fixing ring.

[0014] Preferably, as one possible implementation, the bottom end of the column is installed on the base, the base is placed on the fan foundation pad, and the base is used to adjust the height of the corresponding column.

[0015] Preferably, as one possible implementation, the base has an adjusting tube, and the bottom of the column is inserted into the adjusting tube; the bottom of the column has an external thread, and the bottom of the column is fitted with a nut, which abuts against the top of the adjusting tube.

Detailed Implementation

[0022] When the power of the wind turbine unit is 5.5~8.0MW, the outer diameter of the anchor cage is 5.8~7.0m and the height is 4.5~5.0m.

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0025] See Figure 1 and Figure 2 This embodiment provides an anchor cage installation platform, which includes a working platform 100, a fence 200 and a plurality of columns 300; the plurality of columns 300 are arranged at intervals around the central axis of the anchor cage 700, the working platform 100 and the fence 200 are both installed on the plurality of columns 300, the working platform 100 is in a ring shape and is located between the plurality of columns 300 and the anchor cage 700, and at least a portion of the fence 200 is located above the working platform 100.

[0026] When installing anchor bolts, workers can stand on the work platform 100. The work platform 100 provides workers with a convenient and flat working environment, which greatly reduces the risks and difficulties of working at heights and improves work efficiency compared to workers standing on the narrow surface of the upper anchor plate. At the same time, the railing 200 provides a certain degree of protection on the inside of the work platform 100. Compared with the protection of the back safety belt, it not only improves safety and reduces the risk of injury to workers, but also eliminates the need for a crane, making it particularly suitable for situations where the surrounding space is limited. It should be noted that the height of the work platform 100 can be selected according to the actual size of the anchor bolt cage 700, with the aim of allowing workers to stand on it and perform the corresponding work. Similarly, the width of the work platform 100 can be selected according to the actual size of the anchor bolt cage 700, in order to meet the needs of workers for movement space while maximizing the overall structural stability of the installation platform.

[0027] In addition, since the work platform 100 is circular, workers can walk along the work platform 100 to install all anchor bolts without having to frequently go up and down the work platform 100, which can further improve work efficiency; at the same time, there is no need to set up a mechanism to drive the work platform 100 to move, which is conducive to cost control.

[0028] See also Figure 1 and Figure 2 In this embodiment, a ladder 400 is also provided. The ladder 400 is installed on the work platform 100. The ladder 400 can provide an upward passage for workers. Workers can climb to the work platform 100 through the ladder 400 to carry out their work. Compared with temporary ladders, it is safer.

[0029] Preferably, a safety cage 420 can be installed on the ladder 400 to protect personnel on the ladder 400 and improve safety. Specifically, the safety cage 420 can be a circular safety cage. Both the ladder 400 and the safety cage 420 can be made and welded from steel bars with a diameter of 8mm.

[0030] Preferably, see Figures 1-4 An upward-bending toe guard 110 can be installed on the inner side of the work platform 100 to provide a certain level of protection and reduce the risk of workers falling. In addition, a downward-bending hook 410 can be installed on the ladder 400 so that the ladder 400 can be hung on the toe guard 110 of the work platform 100 via the hook 410 for easy assembly.

[0031] Specifically, the work platform 100 can be set as a number, and the work platforms 100 can be arranged vertically at intervals to meet the work requirements at different heights.

[0032] Toe boards 110 can be installed on each work platform 100. Correspondingly, several hooks 410 arranged vertically at intervals are installed on the ladder 400. The hooks 410 are matched one-to-one with the toe boards 110, and each hook 410 is hung on its corresponding toe board 110. This improves the stability of the ladder 400, making it less prone to swaying and further enhancing safety. The height of the toe boards 110 can be 200mm.

[0033] In fact, each work platform 100 is equipped with a railing 200 to protect the workers standing on each work platform 100.

[0034] Specifically, see [link to relevant documentation] Figure 1 The working platform 100 includes a first platform 120 and a second platform 130. The first platform 120 serves as the working platform for the anchor bolts and lower anchor plate within the anchor bolt cage 700, while the second platform 130 serves as the working platform for the anchor bolts and upper anchor plate within the anchor bolt cage 700. Thus, workers can assemble the anchor bolt cage 700 by working on the first platform 120 and the second platform 130 respectively. In practice, the first platform 120 is slightly higher than the lower anchor plate, and the second platform 130 is lower than the upper anchor plate, with a height difference of approximately 1000mm between them. It should be noted that the height difference between the first platform 120 and the wind turbine foundation pad 800 can be set to 300-700mm, preferably 400-600mm, and specifically around 500mm. For the anchor cage 700 with a total height of 5000~6000mm, the height difference between the second platform 130 and the wind turbine foundation pad 800 can be set to 4000~5000mm, preferably 4200~5700mm, and specifically can be set to about 2500mm.

[0035] In addition, the width of the working platform 100 can be set to 1000~3000mm, preferably 1500~2500mm, and specifically about 2000mm; the height difference between the top of the column 300 and the fan foundation pad 800 can be set to 5500~6500mm, preferably 5700~6300mm, and specifically 6000mm.

[0036] Two rings of railings 200 can be installed above each work platform 100. The height difference between one ring of railings 200 and the corresponding work platform 100 can be set to 500~700mm, preferably 550~650mm, and specifically about 600mm; the height difference between the other ring of railings 200 and the corresponding work platform 100 can be set to 1000~1400mm, preferably 1100~1300mm, and specifically about 1200mm.

[0037] In this embodiment, a fixing ring 500 can also be provided and installed at the middle of several columns 300 to improve the overall structural strength and reduce the risk of bending deformation in the middle of the columns 300. Specifically, the fixing ring 500 can be located between the first platform 120 and the second platform 130.

[0038] Specifically, see Figure 6 A plurality of first through holes 140 are made on the working platform 100, such that the plurality of first through holes 140 correspond one-to-one with a plurality of columns 300; see [link / reference] Figure 7 A plurality of second through holes 510 are provided in the fixing ring 500, such that the plurality of second through holes 510 correspond one-to-one with a plurality of columns 300, and each column 300 is respectively fitted with a clearance fit between the corresponding first through hole 140 and the corresponding second through hole 510. See also... Figure 4 and Figure 5 Furthermore, a first fixing hole and a second fixing hole are made on the column 300. A platform pin 150 can be inserted into the first fixing hole to support the working platform 100 from below, thus securing the working platform 100. A fixing ring pin 520 can be inserted into the second fixing hole to support the fixing ring 500 from below, thus securing the fixing ring 500. The diameter of both the first and second fixing holes is 12mm, and the diameter of both the platform pin 150 and the fixing ring pin 520 is 10mm.

[0039] In addition, see Figure 2 and Figure 8 The bottom end of the column 300 can be installed on the base 600, and the base 600 can be placed on the fan foundation pad 800. The height of each column 300 can be adjusted by adjusting the base 600, so that each working platform 100 can be in a horizontal state.

[0040] Specifically, an adjusting tube 610 can be installed on the base 600, and the bottom of the column 300 is inserted into the adjusting tube 610. An external thread is provided on the bottom of the column 300, and a nut 310 is fitted onto the bottom of the column 300. This nut 310 abuts against the top of the adjusting tube 610, thus, turning the nut 310 allows for convenient height adjustment of the column 300. The external thread on the column 300 can be formed by tapping and can be 10mm in length.

[0041] In fact, the base 600 also has a steel plate, the adjusting pipe 610 is welded to the steel plate, and the steel plate is placed on the fan foundation pad; the dimensions of the steel plate are -12mm×150mm×150mm, the diameter of the adjusting pipe 610 is 48mm, and the diameter of the column 300 is 46mm.

[0042] In addition, a third through hole can be opened on each post 300, and the fence 200 can be inserted through the third through hole to connect the fence 200 and the post 300.

[0043] Specifically, the fence 200 is mainly composed of plastic-coated steel wire. During assembly, one end of the plastic-coated steel wire is passed through the third through hole on each post 300 in sequence along the circumference, and then the two ends of the plastic-coated steel wire are connected and fixed. The two ends of the plastic-coated steel wire can be fixed by binding wire or by clips. The diameter of the third through hole on the post 300 can be 8mm, and the diameter of the plastic-coated steel wire can be 6mm.

[0044] The column 300 can be made of steel pipe, and the adjusting tube 610 of the base 600 can also be made of steel pipe, resulting in high structural strength and reliability.

[0045] See Figure 4 The work platform 100 may include a steel grating 160 and a steel plate 170 covering the top of the steel grating 160, which can ensure strength, reduce weight, and improve the experience of workers standing on it. The steel grating 160 is about 40mm thick, and the steel plate 170 is about 5mm thick.

[0046] During assembly, first place the base 600 in a suitable position within the anchor cage 700, then place the fixing ring 500 and the working platform 100 within the anchor cage 700, ensuring that both the fixing ring 500 and the working platform 100 are coaxial with the anchor cage 700. Adjust the orientation of the working platform 100 and the fixing ring 500 according to the position of the base 600, ensuring that each second through hole 510 on the fixing ring 500 and each first through hole 140 on the working platform 100 are coaxial with the adjusting pipe 610 of the base 600. Insert each column 300 through the corresponding first through hole 140 and second through hole 510 from top to bottom. Within the corresponding adjusting tube 610, the column 300 is made vertical; the working platform 100 and the fixing ring 500 are lifted from bottom to top along the column 300 to the target height, and the nut 310 at the bottom of the column 300 is turned to level the working platform 100; a platform pin 150 is inserted into the first fixing hole to support the working platform 100, and a fixing ring pin 520 is inserted into the second fixing hole to support the fixing ring 500; finally, the hook 410 of the ladder 400 is hung on the toe plate 110 of the working platform 100, and the assembly of the main body of the installation platform is completed.

[0047] During disassembly, simply remove the ladder 400, pull the platform pin 150 out of the first fixing hole, and pull the fixing ring pin 520 out of the second fixing ring. Then, the work platform 100 and the fixing ring 500 can be slid down, and each column 300 can be pulled out from the corresponding first through hole 140 and second through hole 510 to complete the disassembly of the main body of the installation platform.

[0048] This detachable structure facilitates the assembly, disassembly, transport, and storage of the installation platform.

[0049] In this embodiment, there can be 8 columns 300, and the 8 columns 300 are evenly arranged around the center of the anchor cage 700.
