[0002] The wind power foundation is usually a reinforced concrete structure, and after the concrete pouring is completed, the concrete surface needs to be troweled before the concrete solidifies. Since the surface of the concrete is usually a conical surface, it is difficult to use conventional concrete troweling equipment to trowel, and only manual troweling by multiple people can be used.

In the embodiment, the end of the sliding rail 22 is provided with an arc to enable the sliding block 21 to slide from one sliding rail 22 to the adjacent other sliding rail 22 through the arc-shaped track.

[0024] Referring to Figures 1-3 , the adjusting electric cylinder 3 and the multi-stage telescopic electric cylinder 4 are both slidingly connected to the moving plate 2, the multi-stage telescopic electric cylinder 4 is connected to the movable end of the adjusting electric cylinder 3, the adjusting electric cylinder 3 is arranged close to the template at the concrete edge position, and the multi-stage telescopic electric cylinder 4 is arranged close to the template at the concrete center position. The movable end of the multi-stage telescopic electric cylinder 4 is fixedly connected with a support sliding block 41, the support sliding block 41 is slidingly connected with a sliding support rod 42 adjustable in length, the sliding support rod 42 is provided in multiple and corresponds to the support frame 1 one by one, adjacent two sliding support rods 42 are bolted, the two ends of the sliding support rod 42 are respectively slidingly connected to the two connecting rods 13, and the support sliding block 41 can slide between adjacent two sliding support rods 42.

[0025] Referring to Figure 1 and Figure 2 In the embodiment, the moving plate 2 and the sliding block 21 are both provided in three, the moving plate 2 corresponds to the sliding block 21 one by one, the moving plate 2 is uniformly arranged around the center template of the concrete, the adjusting electric cylinder 3 and the multi-stage telescopic electric cylinder 4 are both provided in three and correspond to the moving plate 2 one by one, and the uniformly arranged multi-stage telescopic electric cylinders 4 can more stably drive the six sliding support rods 42 to synchronously slide on the connecting rod 13.

[0026] In particular, referring to Figure 2In the embodiment, the adjustable long edges of the center frame 11, the adjustable long edges of the edge frame 12, the connecting rod 13, the sliding rail 22 and the sliding support rod 42 all adopt a three-section telescopic structure, two side sections of the three-section telescopic structure can slide relative to a middle section, and the side sections of the three-section telescopic structure can be fixed relative to the middle section after sliding.

[0027] With reference to Figure 2 and Figure 3 , the sliding block 21 is connected with a power assembly 5, the power assembly 5 is used to drive the sliding block 21 to slide along the sliding rail 22; the support sliding block 41 is connected with a troweling assembly 6, the troweling assembly 6 is used to trowel the surface of the concrete when moving with the support sliding block 41.

[0028] With reference to Figure 1 and Figure 3 , the adjusting electric cylinder 3 and the multi-stage telescopic electric cylinder 4 are commonly electrically connected with a central control machine 32, the adjusting electric cylinder 3 is preset with multiple telescopic modes, and the multiple telescopic modes one-to-one correspond to multiple telescopic states of the multi-stage telescopic electric cylinder 4, the central control machine 32 is used to switch the telescopic mode of the adjusting electric cylinder 3 when the multi-stage telescopic electric cylinder 4 is extended, the adjusting electric cylinder 3 adjusts one telescopic mode every time the multi-stage telescopic electric cylinder 4 is extended by one stage, so that the support sliding block 41 can always move along an arc trajectory, and the stroke of the adjusting electric cylinder 3 compensates for the distance difference value of the arc trajectory of the support sliding block 41 relative to the straight line trajectory of the sliding block 21. Among them, the multiple telescopic modes of the adjusting electric cylinder 3 can be preset through the central control machine 32 based on the size of the fan foundation and the speed of the power assembly 5 driving the sliding block 21 to slide.

[0029] With reference to Figure 3 , the moving plate 2 is connected with a fixing piece, when the adjusting electric cylinder 3 is telescoped, the fixing piece fixes the adjusting electric cylinder 3 and the moving plate 2, so that the adjusting electric cylinder 3 can conveniently and stably drive the troweling assembly 6 to move on the surface of the concrete; when the adjusting electric cylinder 3 stops telescoping, the fixing piece releases the fixing of the adjusting electric cylinder 3 and the moving plate 2, so that the adjusting electric cylinder 3 can conveniently slide relative to the moving plate 2.

[0030] With reference to Figure 3 and Figure 4 , the support sliding block 41 can rotate relative to the sliding support rod 42, the sliding block 21 and the sliding support rod 42 are commonly provided with an auxiliary assembly 7, the auxiliary assembly 7 includes a fixed part 71 and an auxiliary part 72, the fixed part 71 is arranged on the sliding block 21, and the fixed part 71 is used to fix the sliding block 21 and the moving plate 2 with a fixed fixing force.

[0031] The auxiliary part 72 is provided with six, and one-to-one corresponding to the sliding support rod 42, the auxiliary part 72 is close to the support sliding block 41 sliding into the end of the sliding support rod 42, the auxiliary part 72 is used to make the support sliding block 41 continue to slide after rotating a fixed angle between the adjacent two sliding support rods 42, the fixed angle is twice the acute angle between the vertical plane where the adjusting electric cylinder 3 is located and the vertical plane where the connecting rod 13 is located. In this embodiment, the fixed angle of the support sliding block 41 rotation is 60 degrees.

[0032] When the support sliding block 41 slides to the adjacent two sliding support rods 42, the power assembly 5 can drive the moving plate 2 to rotate relative to the sliding block 21, and after the support sliding block 41 rotates by 60 degrees, the support sliding block 41 can slide on the next sliding support rod 42, so that the support sliding block 41 and the sliding block 21 can slide synchronously on the same support frame 1, and when the support sliding block 41 and the sliding block 21 slide synchronously, the extension direction of the adjusting electric cylinder 3 can be perpendicular to the sliding direction of the sliding block 21, and the fixed part 71 and the auxiliary part 72 can cooperate to make the moving plate 2 and the multi-stage telescopic electric cylinder 4 move smoothly from one support frame 1 to the adjacent another support frame 1.

[0033] In use, the overall size of the support frame 1 is adjusted according to the size of the wind power foundation, so that the six support frames 1 can be bolted around and fitted on the template of the wind power foundation. Since the size of the support frame 1 can be adjusted, the troweling device can be installed on wind power foundations of different sizes to trowel the concrete surface of wind power foundations of different diameters, thereby improving the versatility of the troweling device.

[0034] After the support frame 1 is installed, the power assembly 5 can drive the sliding block 21 to slide along the sliding rail 22, and the sliding block 21 can drive the moving plate 2 to move linearly under the fixed force of the fixed part 71. The moving plate 2 can drive the support sliding block 41 to slide on the sliding support rod 42 through the adjusting electric cylinder 3 and the multi-stage telescopic electric cylinder 4, and the support sliding block 41 can drive the troweling assembly 6 to move close to the concrete surface. After the sliding block 21 slides one circle, the troweling assembly 6 can trowel one annular area of the concrete surface.

[0035] When the support sliding block 41 slides to the adjacent two sliding support rods 42, the auxiliary part 72 can first block the support sliding block 41 from sliding onto the next sliding support rod 42. Due to the blocking effect of the auxiliary part 72, the driving force of the power assembly 5 driving the sliding block 21 to slide can be greater than the fixed force applied by the fixed part 71, so that the moving plate 2 can rotate relative to the sliding block 21, so that the sliding block 21 can continue to slide along the sliding rail 22, and so that the moving plate 2 can drive the support sliding block 41 to rotate.

[0036] During the rotation of the support slider 41 by 60 degrees, the adjusting cylinder 3 stops extending and retracting, the fixing member releases the fixing of the adjusting cylinder 3 and the moving plate 2, and the adjusting cylinder 3 can slide relative to the moving plate 2 to compensate for the increased distance between the support slider 41 and the sliding block 21; after the support slider 41 rotates by 60 degrees, the auxiliary part 72 can release the blocking of the support slider 41, so that the support slider 41 and the sliding block 21 can slide synchronously on one support frame 1; at this time, the fixing member fixes the adjusting cylinder 3 and the moving plate 2, so that the adjusting cylinder 3 can stably drive the troweling assembly 6 to move, thereby enabling the sliding block 21 and the support slider 41 to move from one support frame 1 to another adjacent support frame 1.

[0037] The adjusting cylinder 3 extends and retracts cyclically during the movement of the sliding block 21 to drive the support slider 41 to move in a circular arc trajectory, and the support slider 41 drives the troweling assembly 6 to move in a circular arc, so that the annular area troweled by the troweling assembly 6 is a circular ring, and the troweling area of the troweling assembly 6 can adapt to the circular wind power foundation.

[0038] When it is necessary to replace the troweling area, one section of the multi-stage telescopic cylinder 4 is extended, the multi-stage telescopic cylinder 4 drives the support slider 41 and the troweling assembly 6 to move towards the direction close to the center of the concrete, so that the troweling assembly 6 can trowel the adjacent area of the troweled area, and meanwhile, the central control machine 32 can control the adjusting cylinder 3 to switch to another extension and retraction mode to adapt to the compensation requirement of the circular arc trajectory of the support slider 41 of the adjacent area.

[0039] Based on the above analysis, the adjustable support frame 1 enables the troweling device to adapt to wind power foundations of different sizes, and the telescopic adjustment of the position of the troweling assembly 6 enables the troweling assembly 6 not only to trowel a circular ring area, but also to replace the troweling area conveniently, thereby improving the versatility and use convenience of the troweling device.

[0040] Specifically, referring to Figure 3 , the fixing part 71 comprises a magnetic plate 711 fixedly connected to the sliding block 21, and the moving plate 2 is made of ferromagnetic material and is magnetically connected to the magnetic plate 711; the magnetic attraction force between the magnetic plate 711 and the moving plate 2 forms a fixing force between the moving plate 2 and the sliding block 21, when the external force between the moving plate 2 and the sliding block 21 is not greater than the magnetic attraction force, the moving plate 2 and the sliding block 21 can remain fixed, and when the external force between the moving plate 2 and the sliding block 21 is greater than the magnetic attraction force, the moving plate 2 and the sliding block 21 can rotate relative to each other, so that the moving plate 2 and the sliding block 21 can form a fixed fixing force.

[0041] Specifically, referring to Figure 4 , the auxiliary part 72 comprises a baffle 721, a baffle piece 722 and a push plate 723.

[0042] With reference to Figures 2-4 A support sliding hole 421 is formed in the slide rod 42, the support sliding block 41 is slidingly arranged in the support sliding hole 421, and the support sliding block 41 can rotate in the support sliding hole 421. The baffle 721 is hinged in the accommodation slot 422 formed in the side wall of the support sliding hole 421, and the baffle 721 is located at the side of the support sliding hole 421 close to the edge frame 12. The baffle 721 can be completely placed in the accommodation slot 422, so that the support sliding block 41 can slide to the middle part of the slide rod 42. The first torsion spring 7211 is fixed between the baffle 721 and the slide rod 42, and the first torsion spring 7211 is located at the hinge of the baffle 721. The first torsion spring 7211 is used to drive the baffle 721 to block the support sliding hole 421.

[0043] The baffle piece 722 is slidingly arranged in the hole wall of the support sliding hole 421 and is located at the side of the support sliding hole 421 away from the edge frame 12. The baffle piece 722 is used to block the baffle 721 from being placed in the accommodation slot 422. The push plate 723 is fixedly connected with the baffle piece 722, and the auxiliary spring 7231 for driving the baffle piece 722 to slide into the support sliding hole 421 is fixed between the push plate 723 and the slide rod 42. The auxiliary spring 7231 is located in the spring groove 423 formed in the slide rod 42. Six push rods 411 are fixedly connected to the support sliding block 41, and the push rods 411 correspond to the push plate 723 one by one.

[0044] With reference to Figure 4 The accommodation gap 7232 for the push rod 411 to slide through is formed in the push plate 723, and the accommodation plate 7233 is arranged at the accommodation gap 7232. The accommodation plate 7233 is hinged with the push plate 723, and the limiting plate 7234 is arranged on the side of the accommodation plate 7233 away from the support sliding hole 421. The limiting plate 7234 is fixedly connected to the push plate 723. The second torsion spring 7235 is fixed between the accommodation plate 7233 and the push plate 723, and the second torsion spring 7235 is located at the hinge of the accommodation plate 7233. The second torsion spring 7235 is used to drive the accommodation plate 7233 to abut against the limiting plate 7234.

[0045] With reference to Figure 3 and Figure 4 The push rod 411 is used to push the corresponding accommodation plate 7233 away from the baffle 721 when the support sliding block 41 rotates, so that the baffle piece 722 slides out of the support sliding hole 421. The length of the baffle 721 is less than the length of the push plate 723, and the support sliding block 41 can slide through the baffle 721 first and then slide through the push plate 723, so that the baffle 721 can reset the baffle piece 722 first.

[0046] When the support sliding block 41 slides to between two adjacent slide support rods 42, the push rod 411 can push the swing of the let-in plate 7233 to slide through the let-in plate 7233, and the baffle plate 721 can be blocked by the blocking piece 722 to block the support sliding block 41 from sliding into the next slide support rod 42. Under the driving of the power assembly 5 to the sliding block 21, the support sliding block 41 can rotate with the moving plate 2, and the push rod 411 can gradually approach the let-in plate 7233. After the support sliding block 41 rotates by 60 degrees, the push rod 411 can push the let-in plate 7233 away from the baffle plate 721, and the let-in plate 7233 drives the push plate 723 away from the baffle plate 721 under the action of the limiting plate 7234, and the push plate 723 can drive the blocking piece 722 to slide out of the support sliding hole 421. At this time, the support sliding block 41 can slide on a support frame 1 synchronously with the sliding block 21, and the support sliding block 41 can push the baffle plate 721 to rotate into the let-in groove 422.

[0047] After the support sliding block 41 slides through the baffle plate 721, the support sliding block 41 still pushes the push plate 723 with the push rod 411 to make the blocking piece 722 unable to reset. At this time, the baffle plate 721 can be reset under the elastic force of the first torsional spring 7211; after the support sliding block 41 slides through the push plate 723, the push rod 411 releases the pushing force on the push plate 723.

[0055] Since the first mounting box 621 is hinged to the movable end of the troweling telescopic rod 611, the troweling turntable 623 connected to the output shaft of the troweling motor 622 can be adapted to flip with the conical surface of the concrete, so that the troweling turntable 623 can be perpendicular to the conical surface of the concrete, so that the troweling plate 624 can be directly abutted on the conical surface of the concrete; the nut is tightened, the connecting block 6211 and the connecting branch plate 6111 are fixed, the troweling motor 622 drives the troweling turntable 623 to rotate, the troweling turntable 623 drives the troweling plate 624 to rotate, and under the elastic force of the surface spring 625, the troweling plate 624 can swing relative to the troweling turntable 623 with the conical surface of the concrete, so that the troweling turntable 623 can be attached to the conical surface of the concrete for troweling.

Since there is a circular arc transition between the two adjacent power racks 54 and the two adjacent sliding rails 22, the power gear 53 can be transmitted to another adjacent power rack 54, and the sliding block 21 can slide to another adjacent sliding rail 22 under the drive of the power gear 53, so that the sliding block 21 can slide a full circle along the sliding rail 22.
