[0037] During the maintenance process of the high-pile cap foundation of offshore wind power, in order to ensure the efficient progress of the repair work of the side concrete and the painting of anti-corrosion paint, devices such as hanging boards and hanging baskets are usually required.
[0038] When the hanging board or hanging basket is constructed on the side of the high-pile cap foundation of offshore wind power, it needs to be lowered from the highest point of the cap and constructed step by step from top to bottom. After the construction of the bottom of the cap side is completed, the staff needs to return to the top of the cap, change the position of the hanging board or hanging basket, and then continue the operation.
[0039] However, the working surface of the hanging board or hanging basket is small. During the operation of the hanging board or hanging basket, the position of the hanging board or hanging basket needs to be frequently changed, resulting in low construction efficiency.
[0040] To solve the above problems, the embodiments of the present application provide an auxiliary device for maintaining the high-pile cap of wind power. By hanging the connecting part of the hanging ladder on the top of the high-pile cap of wind power and making the straight ladder part located on the outer wall of the high-pile cap of wind power, it is convenient for the operators to work by climbing the straight ladder part; after completing the operation near the position of the hanging ladder, the hanging ladder is assisted to slide on the high-pile cap of wind power through the sliding part, and after sliding to the next operation position, the hanging ladder is locked by the locking part. The operators can quickly move up and down on the hanging ladder, and by sliding the hanging ladder, quickly adjust the position of the hanging ladder, so as to facilitate the operators to quickly carry out the operation at the next position, thereby improving the operation efficiency.
[0041] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.
[0042] An embodiment of the present application provides an auxiliary device for maintaining a high-pile cap of a wind turbine. Referring to Figure 1 、 Figure 2 and Figure 3 , the auxiliary device for maintaining a high-pile cap of a wind turbine includes:
[0043] A hanging ladder 100, which includes a connecting portion 110 and a straight ladder portion 120. The connecting portion 110 is hung inside the top of the high-pile cap 1 of the wind turbine, and the straight ladder portion 120 is connected to the connecting portion 110 and abuts against the outer wall of the high-pile cap 1 of the wind turbine;
[0044] A sliding member 200, which is connected to the connecting portion 110 to assist the connecting portion 110 in sliding along the axial direction of the high-pile cap 1 of the wind turbine on the high-pile cap 1 of the wind turbine;
[0045] A locking member 300, which is arranged on the connecting portion 110 to fix the connecting portion 110 on the high-pile cap 1 of the wind turbine.
[0046] By adopting the above technical solution, the connecting portion 110 of the hanging ladder 100 is hung on the top of the high-pile cap 1 of the wind turbine, and the straight ladder portion 120 is located on the outer wall of the high-pile cap 1 of the wind turbine, so as to realize the connection between the hanging ladder 100 and the high-pile cap 1 of the wind turbine, facilitating the operator to work by climbing the straight ladder portion 120; after completing the work near the position of the hanging ladder 100, the sliding member 200 assists the hanging ladder 100 to slide on the high-pile cap 1 of the wind turbine. After sliding to the next working position, the hanging ladder 100 is locked by the locking member 300; the operator can move up and down quickly on the hanging ladder 100, and by sliding the hanging ladder 100, the position of the hanging ladder 100 can be quickly adjusted, facilitating the operator to quickly carry out the work at the next position, thereby improving the work efficiency.
[0047] Exemplarily, the auxiliary device for maintaining a high-pile cap of a wind turbine provided by the embodiment of the present application is not limited to being used on the high-pile cap 1 of a wind turbine, and can also be used on other building high platforms, which will not be elaborated here.
[0048] Wherein, the height of the straight ladder portion 120 matches the height of the high-pile cap 1 of the wind turbine. The straight ladder portion 120 can also adopt a telescopic ladder to facilitate storage and transportation.
[0049] In some embodiments, referring to Figure 2, the connecting portion 110 includes a hook 111 and a connecting rod 112. The connecting rod 112 is connected to the top of the straight ladder portion 120 and is perpendicular to the straight ladder portion 120. The hook 111 is provided at one end of the connecting rod 112 away from the straight ladder portion 120, and the hook 111 is used to abut against the inner side wall of the wind power high-pile cap 1.
[0050] Wherein, both the connecting rod 112 and the hook 111 are provided with two. The two connecting rods 112 are fixedly connected by parallel bolts to the top of the straight ladder portion 120, and the two hooks 111 are respectively welded and fixed to the ends of the two connecting rods 112, so as to increase the contact area between the connecting rod 112 and the top of the wind power rigid pile cap, reduce the shaking of the straight ladder portion 120, improve the stability of the device, and facilitate the operation of the operator on the straight ladder portion 120.
[0051] Exemplarily, referring to Figure 3 , the hook 111 is a straight rod. The hook 111 is welded and fixed to the end of the connecting rod 112 away from the straight ladder portion 120. The connecting rod 112 is bolted and fixed to the top of the straight ladder portion 120. The hook 111 is parallel to the straight ladder portion 120, so that the hook 111, the connecting rod 112 and the straight ladder portion 120 form a groove shape, and the hanging ladder 100 is erected on the top of the wind power high-pile cap 1, so that the hook 111 abuts against the inner side wall of the wind power high-pile cap 1, and the straight ladder portion 120 abuts against the outer side wall of the wind power high-pile cap 1, thereby realizing the fixation of the hanging ladder 100.
[0052] Exemplarily, referring to Figure 1 and Figure 2 , a chute 600 is provided on the wind power high-pile cap 1. The chute 600 is circumferentially arranged on the inner side wall of the top of the wind power high-pile cap 1, and the hook 111 is used to be inserted into the chute 600.
[0053] At this time, the hook 111 is a curved hook, and the hook 111 is inserted into the chute 600. On the one hand, the chute 600 provides a track for the movement of the hook 111; on the other hand, after the hook 111 is inserted into the chute 600, the hook 111 abuts against the wall of the chute 600, thereby further reducing the possibility of the hook 111 disengaging from the chute 600 and reducing the possibility of the hanging ladder 100 disengaging from the wind power high-pile cap 1, and improving the safety of the device.
[0054] Furthermore, the sliding member 200 includes a first roller 210. The first roller 210 is rotatably connected to the hook 111, and the first roller 210 is rotatably connected to the inner side wall of the wind power high-pile cap 1. The rotation axis of the first roller 210 is parallel to the length direction of the straight ladder portion 120.
[0055] The first roller 210 is provided on both of the two hooks 111.
[0056] The hook 111 is inserted into the chute 600, and the first roller 210 on the hook 111 is also located within the chute 600 and abuts against the inner sidewall of the chute 600 to facilitate the sliding of the hook 111 within the chute 600. At this time, the hook 111 and the chute 600 are mainly in contact through the first roller 210. When it is necessary to move the hanging ladder 100, the operator stands on the straight ladder part 120, holds the wind power high-piled cap 1 by hand and exerts force towards the side, which can drive the first roller 210 to slide within the chute 600 and reduce the sliding resistance.
[0057] In some embodiments, referring to Figure 3 , the sliding member 200 includes a rotating shaft 220 and a second roller 230. The rotating shaft 220 is rotatably connected to the connecting rod 112. The rotation axis of the rotating shaft 220 is parallel to the length direction of the straight ladder part 120. The second roller 230 is rotatably connected to the rotating shaft 220, and the second roller 230 abuts against the top of the wind power high-piled cap 1.
[0058] Both the rotating shaft 220 and the second roller 230 are provided in two, and are respectively arranged on the two connecting rods 112.
[0059] In this embodiment, the rotating shaft 220 is rotatably connected to the connecting rod 112 and is perpendicular to the connecting rod 112. The second roller 230 is rotatably connected to the rotating shaft 220. The rotation axis of the second roller 230 is parallel to the length direction of the connecting rod 112. The second roller 230 is placed on the top plane of the wind power high-piled cap 1 to roll along the top plane of the wind power high-piled cap 1.
[0060] By adopting the above technical solution, the second roller 230 bears the main gravity of the hanging ladder 100, so that the operator can stand on the hanging ladder 100 and easily move the hanging ladder 100, which is convenient for the movement of the hanging ladder 100 and reduces the operation difficulty of the operator. Moreover, the second roller 230 is rotatably connected to the connecting rod 112 through the rotating shaft 220, so that during the rolling process of the second roller 230 on the wind power high-piled cap 1, the position of the second roller 230 can be adjusted according to the curvature of the wind power high-piled cap 1, playing a role in turning, thereby improving the applicability of the device. And the whole device is always hung on the wind power high-piled cap 1, restricting the movement angle of the hanging ladder 100.
[0061] In some embodiments, referring to Figure 2 , the locking member 300 includes a locking rod. A plurality of locking holes 310 are provided on the wind power high-piled cap 1. The locking rod is slidably arranged on the connecting part 110. The locking rod is used to be inserted into any one of the locking holes 310 to fix the connecting part 110.
[0062] Exemplarily, the locking holes 310 can be formed in the top plane of the wind power high-piled cap 1 and are evenly distributed around the axis of the wind power high-piled cap 1. The locking rod can be a screw rod, and the screw rod is threadedly inserted into the connecting rod 112. When the hanging ladder 100 moves to the desired position, the screw rod is rotated, the screw rod is removed from the connecting rod 112, and is inserted into the locking hole 310, so as to limit the movement of the connecting rod 112 and realize the fixation of the hanging ladder 100.
[0063] Exemplarily, the locking holes 310 can also be formed in the inner side wall of the top of the wind power high-piled cap 1, and the positions of the plurality of locking holes 310 are on the same circumference. At this time, the locking rod is adaptively installed on the hook 111. By adjusting the locking rod to pass through the hook 111 and be inserted into the locking hole 310, the fixation of the hook 111 can be realized, and at the same time, the separation of the hook 111 from the sliding groove 600 can be hindered, improving the stability of the connection of the device.
[0064] In some embodiments, referring to Figure 1 and Figure 2 , the wind power high-piled cap maintenance auxiliary device further includes a plurality of anti-falling members 400. The anti-falling members 400 include an arc-shaped ring. The arc-shaped ring is arranged on the side of the straight ladder part 120 away from the connecting part 110, and a passage for the operator to pass through is formed between the arc-shaped ring and the straight ladder part 120.
[0065] Among them, the arc-shaped ring is a steel ring. The arc-shaped ring is fixed on the side of the straight ladder part 120 away from the connecting part 110 by a pin, and the plurality of arc-shaped rings are evenly distributed, so as to provide stable safety protection for the operator.
[0066] Among them, a protective layer is coated on the arc-shaped ring.
[0067] Exemplarily, the protective layer is a rubber layer. The protective layer not only has an anti-slip effect, but also increases the comfort of the arc-shaped ring, avoiding the possibility of the operator being scratched by the arc-shaped ring during the operation.
[0068] In some embodiments, a standing pedal 500 is arranged on the side of the straight ladder part 120 away from the connecting part 110, and the width of the standing pedal 500 is greater than the width of the straight ladder part 120.
[0069] The standing pedal 500 is independent of the ladder of the straight ladder part 120, and the width of the standing pedal 500 is greater than the ladder of the straight ladder part 120, so that it is convenient for the operator to stand on the standing pedal 500 to perform operations. The standing pedal 500 is arranged in a staggered manner with the arc-shaped ring, so as to facilitate the up and down movement of the operator on the ladder.
[0070] In the embodiment of the present application, two standing pedals 500 are provided, and the two standing pedals 500 are respectively arranged at the bottom and the middle of the straight ladder part 120 to provide an operation platform for the operator.
[0071] Furthermore, the standing pedal 500 is detachably connected to the straight ladder part 120.
[0072] The standing pedal 500 is detachably connected to the straight ladder part 120 through bolts or snap structures, so as to facilitate the disassembly and assembly of the standing pedal 500 at any time, and the standing pedal 500 can be installed at any height of the straight ladder part 120, which is more convenient for the operation of the operators and reduces the restriction of the standing pedal 500 on the climbing of the operators.
[0073] An auxiliary device for maintaining a wind power high-piled cap provided by an embodiment of the present application hangs the connecting part 110 of the hanging ladder 100 on the top of the wind power high-piled cap 1, and makes the straight ladder part 120 located on the outer wall of the wind power high-piled cap 1, so as to facilitate the operators to operate by climbing the straight ladder part 120; after completing the operation near the position of the hanging ladder 100, the sliding part 200 is used to assist the hanging ladder 100 to slide on the wind power high-piled cap 1, and after sliding to the next operation position, the locking part 300 is used to lock the hanging ladder 100. The operators can move up and down quickly on the hanging ladder 100, and by sliding the hanging ladder 100, the position of the hanging ladder 100 can be quickly adjusted, so as to facilitate the operators to quickly perform the operation at the next position, thereby improving the operation efficiency.
