Description

Technical Field

[0001] The invention relates to the technical field of pipe segment maintenance, and in particular to a prefabricated assembled concrete wind power tower arc pipe segment maintenance device. Background Art

[0002] A wind turbine tower refers to a wind turbine tower pole, which plays a supporting role in a wind turbine generator set and absorbs the vibration of the unit. Wind turbine towers are mainly divided into two types: metal towers and concrete towers.

[0003] During the forming process of the concrete tower, concrete is usually poured into multiple curved segments first, and then the multiple curved segments are spliced ​​to form a complete concrete tower. In order to ensure the service strength of the concrete tower, the formed curved segments need to be cured. Keeping the surface moist during the curing process can avoid the concrete from dehydrating too quickly and causing cracks, improve the surface quality of the concrete, and improve the durability of the overall structure. It can also reduce the damage and wear of the concrete curved segments during use, extend their service life, and reduce subsequent maintenance costs.

[0004] When the existing technology is used to maintain the curved tube segments of the concrete wind turbine tower, the cast curved tube segments are usually first fixed on the ground, and then the curved tube segments are immersed in water for maintenance through a manual handheld water pipe. However, due to the excessive height of the curved tube segments, the water sprayed from the handheld water pipe cannot soak the upper end of the curved tube segments, and the lower end of the curved tube segment is tightly attached to the ground, and the bottom of the curved tube segment cannot be soaked, thereby reducing the wetting effect of the curved tube segment. In addition, a large amount of splashing will occur after the water flow sprayed from the water pipe contacts the curved tube segment, resulting in part of the water being unable to soak the curved tube segment, thereby increasing water consumption.

[0034] See also Figure 1-Figure 4 A prefabricated assembled concrete wind power tower arc segment maintenance device comprises a water collecting frame 1, and a valve is arranged on the frame wall of the water collecting frame 1.

[0035] During specific operation, the water collecting frame 1 is hoisted to the working position by an existing crane, and then the water collecting frame 1 is separated from the crane. Initially, the valve is in a closed state.

[0036] See also Figure 1 and Figure 2The prefabricated assembled concrete wind power tower arc segment maintenance device also includes a support unit 2, which is arranged inside the water collecting frame 1. The support unit 2 includes a rectangular frame 21 arranged just above the water collecting frame 1. The inner end surfaces of the front and rear frame walls of the rectangular frame 21 are both provided with a plurality of arc openings 22 evenly distributed from left to right. The upper ends of the left and right frame walls of the rectangular frame 21 are both provided with sliding grooves 23. A supporting component 24 is commonly provided between the two arc openings 22 in the same longitudinal direction, and the bottom of the supporting component 24 is in contact with the bottom wall of the water collecting frame 1.

[0037] See also Figure 2 The support unit 2 further includes four support columns 25 distributed in a rectangular shape and closely attached to the upper end of the bottom wall of the water collecting frame 1 , and the upper ends of the four support columns 25 are fixedly connected to the lower end of the rectangular frame 21 .

[0038] During specific operation, the rectangular frame 21 is lifted by the existing crane, and the rectangular frame 21 drives the multiple supporting components 24 to move through the multiple arc-shaped openings 22 until the multiple supporting components 24 move into the water collecting frame 1 and contact the bottom wall of the water collecting frame 1. At the same time, the rectangular frame 21 drives the four supporting columns 25 to contact the bottom wall of the water collecting frame 1, thereby improving the stability of the multiple supporting components 24 placed in the water collecting frame 1, and then the crane is separated from the rectangular frame 21.

[0039] See also Figure 1 and Figure 5 The supporting component 24 includes two connecting rods 241 which are symmetrically distributed front and back and are fixedly connected to the middle sections of the corresponding two arc-shaped openings 22 respectively. A supporting frame 242 is commonly installed at the lower ends of the two connecting rods 241. Distance adjustment components 243 are arranged on the left and right side walls of the supporting frame 242. A bottom immersion component 244 is arranged on the bottom wall of the supporting frame 242.

[0040] See also Figure 5 , Figure 7 and Figure 8 The distance adjustment component 243 includes an arc-shaped slide groove 2431 opened on the inner end surface of the side frame wall of the supporting frame 242, and a movable baffle 2432 is slidably connected inside the arc-shaped slide groove 2431. The upper end of the movable baffle 2432 is provided with an inclined surface inclined toward the inside of the supporting frame 242, and a distance adjustment screw 2433 is installed at one end of the movable baffle 2432 away from the inside of the supporting frame 242, and the distance adjustment screw 2433 is threadedly connected to the side frame wall of the supporting frame 242.

[0041] In specific operation, before placing the arc segment, according to the thickness of the arc segment, two pitch-adjusting screws 2433 in the plurality of support frames 242 are rotated in sequence, and the pitch-adjusting screws 2433 drive the movable baffles 2432 to move in the arc-shaped slide groove 2431, thereby changing the spacing between the two movable baffles 2432 to be consistent with the thickness of the arc segment, realizing the function of limiting the arc segments of different thicknesses from the bottom, avoiding the phenomenon of the arc segment being tilted, and improving the arc segment after being placed. Stability, then the multiple arc-shaped pipe segments that need to be maintained are hoisted into the supporting frame 242 in turn by a crane. During the movement of the arc-shaped pipe segment, it first passes through the rectangular frame 21 and moves downward along the two connecting rods 241 until it passes between the two movable baffles 2432 and contacts the bottom wall of the supporting frame 242. The two movable baffles 2432 limit the placed arc-shaped pipe segments, and the inclined surface on the movable baffle 2432 facilitates the arc-shaped pipe segment to enter the space between the two movable baffles 2432 during the descent.

A height adjustment component 32 is installed on the upper end of the moving block 31, and a strip plate 33 is commonly connected to the two height adjustment components 32.

[0043] See also Figure 1 , Figure 5 and Figure 6 The height-adjusting component 32 includes a positioning frame 321 installed at the upper end of the moving block 31 and opening upward, a lifting rod 322 is slidably connected in the positioning frame 321, the upper end of the lifting rod 322 is fixedly connected to the lower end of the strip plate 33, and a plurality of distance-adjusting through holes 323 evenly distributed from top to bottom are opened on the lifting rod 322, and a plug-in rod 324 is slidably penetrated by the left and right frame walls of the positioning frame 321, and the plug-in rod 324 is plugged into and matched with any one of the distance-adjusting through holes 323.

[0044] During specific operation, the two moving blocks 31 are at the extreme ends of the two sliding grooves 23. According to the height of the arc-shaped pipe segment to be maintained, the connecting rod 324 is first separated from the distance-adjusting through hole 323 and the positioning frame 321, and then the two lifting rods 322 are pushed as required. The two lifting rods 322 drive the strip plate 33 to move until the strip plate 33 moves to the required height, and then the connecting rod 324 is plugged into the frame wall of the positioning frame 321 and plugged into and matched with the distance-adjusting through hole 323 at the corresponding position, thereby realizing the function of limiting the lifting rod 322 after the distance adjustment, and further realizing the function of limiting the strip plate 33.

[0045] See also Figure 1 , Figure 2 and Fig. 9 The middle section of the strip plate 33 is provided with a plurality of rectangular through holes 34 evenly distributed from left to right, and a displacement component 35 is arranged in the rectangular through hole 34 , and a water spray component 36 is connected to the displacement component 35 .

[0047] See also Figure 1 , Figure 2 , Figure 5 and Fig. 9 The water spray component 36 includes a water inlet pipe 361 installed through the middle of the sliding block 352, and a water storage tank 362 is installed at the lower end of the water inlet pipe 361 and connected to the water storage tank 362. The left and right ends of the water storage tank 362 are symmetrically connected with adjustment components 363, and the adjustment component 363 is connected to a water spray component 365. A connecting hose 364 is fixedly connected between the water spray component 365 and the water storage tank 362. A plurality of evenly distributed water spray holes are opened on the bottom wall of the water storage tank 362, and a guide component 366 is connected to the adjustment component 363.

[0048] During specific operation, before operation, multiple water inlet pipes 361 are connected to existing water pumps outside through connecting pipes. Initially, the strip plate 33 is located above the frame wall of the rectangular frame 21 through two height adjustment components 32 and two moving blocks 31. The strip plate 33 drives multiple water spray components 36 to be located in the corresponding arc-shaped openings 22 through multiple displacement components 35, thereby avoiding affecting the placement of the arc-shaped pipe segments.

[0049] See also Figure 2 , Figure 5 and Fig. 9 The adjusting assembly 363 includes an adjusting screw 3631 rotatably connected to the end wall of the water storage tank 362, and an L-shaped plate 3632 is threadedly connected to the adjusting screw 3631. The horizontal section of the L-shaped plate 3632 is close to the lower end of the water storage tank 362, and the lower end of the horizontal section of the L-shaped plate 3632 is fixedly connected to the upper end of the water spray assembly 365.

[0050] See also Figure 1 , Figure 2 , Figure 5 and Fig. 9The water spray assembly 365 includes a first connecting pipe 3651 installed at the lower end of the horizontal section of the L-shaped plate 3632, the first connecting pipe 3651 is fixedly connected and communicated with the connecting hose 364, a plurality of splicing pipes 3652 are threadedly connected to the lower end of the first connecting pipe 3651, and the plurality of splicing pipes 3652 are connected by threaded connection, and a second connecting pipe 3653 is threadedly connected to the lower end of the splicing pipe 3652 located at the bottom, and a plurality of evenly distributed water spray pipes 3654 are installed and communicated on the first connecting pipe 3651, the splicing pipe 3652 and the second connecting pipe 3653, and the nozzles of the water spray pipes 3654 face the symmetry axes of the two adjusting assemblies 363.

[0051] During specific work, according to the height of the arc-shaped pipe segment, multiple splicing pipes 3652 are selected for threaded splicing, and then the multiple splicing pipes 3652 after splicing are threadedly connected to the first connecting pipe 3651, and then the second connecting pipe 3653 is threadedly connected to the splicing pipe 3652 located at the bottom, to ensure that the spacing between the first connecting pipe 3651, the multiple splicing pipes 3652 and the second connecting pipe 3653 matches the height of the arc-shaped pipe segment, and then according to the thickness of the arc-shaped pipe segment, the two adjusting screws 3631 on the same water storage tank 362 are rotated in turn, the two adjusting screws 3631 drive the two L-shaped plates 3632 to move, and the two L-shaped plates 3632 drive the two water spraying assemblies 365 to move, thereby changing the spacing between the two water spraying assemblies 365 so that their working spacing matches the thickness of the arc-shaped pipe segment.

[0052] See also Figure 2 , Figure 5 and Fig. 9 The guide assembly 366 includes a connecting column 3661 installed at the lower end of the horizontal section of the L-shaped plate 3632, and a guide frame 3662 with a U-shaped structure and an opening facing the two symmetry axes of the adjustment assembly 363 is installed at the lower end of the connecting column 3661. Two rotating wheels 3663 are rotatably connected to both ends of the opening of the guide frame 3662.

[0053] During specific operation, the water spray assembly 365 is initially located in the space between the corresponding arc-shaped opening 22 and the connecting rod 241. When the spacing between the two water spray assemblies 365 is adjusted, the two L-shaped plates 3632 simultaneously drive the two connecting columns 3661 to move, and the two connecting columns 3661 drive the four rotating wheels 3663 on both sides to move through the two guide frames 3662, thereby changing the spacing between the rotating wheels 3663 on both sides to match the thickness of the arc-shaped pipe segment.

[0054] After the spacing between the rotating wheels 3663 on both sides is adjusted, the existing traction equipment is connected to the strip plate 33, and then the water pump and the traction equipment are started. The water pump injects the water required for maintenance into the multiple water storage tanks 362 through the multiple connecting pipes and the water inlet pipe 361. A part of the water in the water storage tank 362 is sprayed out from the multiple water spray holes on the bottom wall thereof, and the other part is injected into the two first connecting pipes 3651 through the two connecting hoses 364, and then injected into the multiple splicing pipes 3652 and the second connecting pipes 3653 in turn, and then sprayed out from the multiple water spray pipes 3654. At the same time, the traction equipment drives the strip plate 33 to move, and the strip plate 33 drives the multiple sliding blocks 352 to move through the multiple rectangular through holes 34, and the multiple sliding blocks 352 drive the multiple sliding blocks 352 through the water inlet pipe 361. Multiple water storage tanks 362 move, and the water storage tanks 362 drive two L-shaped plates 3632 to move through two adjusting screws 3631, and the two L-shaped plates 3632 drive two water spraying assemblies 365 and two connecting columns 3661 to move, and the two connecting columns 3661 drive the rotating wheels 3663 on both sides to contact the inner and outer arc surfaces of the arc-shaped pipe segment through two guide frames 3662 and move along the curvature of the arc-shaped pipe segment. When the rotating wheels 3663 on both sides move along the curvature of the arc-shaped pipe segment, they are subjected to the squeezing force of the arc-shaped pipe segment, and thus transmitted to the two L-shaped plates 3632 through the two guiding frames 3662 and the two connecting columns 3661. The two L-shaped plates 3632 are subjected to the force and transmitted to the water storage tank 365 through the two adjusting screws 3631. 62, the water storage tank 362 is subjected to force and drives the sliding block 352 to slide in the rectangular through hole 34 through the water inlet pipe 361, and the sliding block 352 drives the two cylindrical rods 353 to slide in the corresponding two cylindrical grooves 351, so as to limit the horizontal position of the sliding block 352 and guide the moving direction of the sliding block 352, thereby ensuring that the rotating wheels 3663 on both sides are always in contact with the inner and outer arc surfaces of the arc-shaped pipe segment. When the water storage tank 362 and the two water spraying assemblies 365 initially move, the vertical side walls of the arc-shaped pipe segment are first soaked, and then the moving water storage tank 362 sprays water through multiple water spraying holes to soak the upper end surface of the arc-shaped pipe segment. At the same time, the two water spraying assemblies 365 on both sides of the arc-shaped pipe segment spray water through multiple water spraying pipes 365 The sprayed water wets the inner and outer arc surfaces of the arc-shaped segments, and the L-shaped plate 3632 moves while driving the water spray assembly 365 to move. The distance between the water spray assembly 365 and the arc-shaped segments is short and remains consistent during the movement, thereby avoiding the phenomenon of excessive distance between the water spray assembly 365 and the arc-shaped segments. Therefore, there is no need to pressurize the water flow required for maintenance, thereby effectively reducing the splashing degree after the water flow contacts the arc-shaped segments and avoiding water waste. Under the action of the traction equipment, the multiple water storage tanks 362 and the multiple water spray assemblies 365 wet the multiple arc-shaped segments for maintenance. After all the arc-shaped segments are wetted, the traction equipment is turned off, and the multiple water spray assemblies 365 are located inside the corresponding arc-shaped openings 22.

[0055] See also Figure 5 , Figure 7 and Figure 8 The bottom immersion component 244 includes a plurality of evenly distributed water collecting grooves 2441 opened at the upper end of the bottom wall of the supporting frame 242, a drainage hole 2442 is opened in the middle of the bottom wall of the water collecting groove 2441, a sliding opening 2443 connected to the plurality of drainage holes 2442 is opened in the middle of the lower end of the bottom wall of the supporting frame 242, a sealing plate 2444 with an L-shaped structure is slidably connected in the sliding opening 2443, a positioning rod 2445 is slidably penetrated in the middle of the vertical section of the sealing plate 2444, and the positioning rod 2445 is fixedly connected to the side frame wall of the supporting frame 242.

[0056] In specific operation, during the soaking process, the water sprayed by the water spray assembly 365 and the water storage tank 362 will slide downward along the surface of the arc-shaped pipe segment, thereby entering the support frame 242, and the multiple water collection grooves 2441 on the bottom wall of the support frame 242 can collect the falling water. At the same time, the multiple water collection grooves 2441 effectively reduce the contact area between the lower end of the arc-shaped pipe segment and the bottom wall of the support frame 242. The water in the water collection groove 2441 directly contacts the bottom of the arc-shaped pipe segment, realizing the function of soaking the bottom of the arc-shaped pipe segment, thereby reducing the arc-shaped pipe segment that is not soaked. The maintenance area improves the maintenance effect of the arc segment. After the maintenance of the arc segment is completed, if there is still water remaining in the water collecting tank 2441, the sealing plate 2444 is pulled out from the sliding opening 2443, thereby releasing the seal of the drainage hole 2442, and the water in the water collecting tank 2441 is discharged from the drainage hole 2442 to the water collecting frame 1, and then the water in the water collecting frame 1 is discharged and collected from the valve for the next maintenance treatment, thereby avoiding rust on the supporting frame 242, and then the sealing plate 2444 is reset, and the maintenance treatment of the arc segment is completed.
