[0021] ​​To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] like Figures 1-4 As shown, one embodiment of this application provides a concrete pouring surface leveling device, including a fixing plate 1 and a column 2. The fixing plate 1 has through holes corresponding to the anchor positions. A vertical cylinder 3 is fixed to the top of the fixing plate 1. A turntable 4 is rotatably connected to the upper end of the vertical cylinder 3. A motor 5 is installed inside the vertical cylinder 3, and its output shaft is fixed to the center of the turntable 4. The turntable 4 is fixed to the column 2 by a horizontal bar 6. A vertical bar 7 is vertically fixed on the horizontal bar 6. A connecting rod 8 is provided between the vertical bar 7 and the column 2. A pressure cylinder 9 for flattening the pouring surface on the fan foundation 15 is rotatably connected to the connecting rod 8. A caster wheel 10 is installed at the bottom of the column 2.

[0023] During installation, after the concrete of the wind turbine foundation 15 is poured, the through holes on the fixing plate 1 are fitted into the anchor rods, and the fixing plate 1 is fixed to the top center of the wind turbine foundation 15 with bolts. The column 2 is vertically installed on one side of the wind turbine foundation 15 and fixed to the turntable 4 by the horizontal bar 6. The vertical bar 7 is vertically fixed to the horizontal bar 6 at the upper end of the inclined surface of the wind turbine foundation 15. The two ends of the connecting rod 8 connect the column 2 and the vertical bar 7, so that the inclination angle is consistent with the inclination angle of the conical surface of the wind turbine foundation 15. The pressure cylinder 9 is pressed on the conical inclined surface of the wind turbine foundation 15.

[0024] In use, the starter motor 5 drives the turntable 4 to rotate, and the turntable 4 drives the column 2 and the vertical bar 7 to rotate in a ring around the fan foundation 15 via the crossbar 6. The pressure cylinder 9 below the crossbar 6 rolls around the conical pouring surface to flatten it.

[0025] In this embodiment, the fixing plate 1 uses the anchor bolts of the wind turbine foundation 15 itself to fix the turntable 4 and the motor 5. The motor 5 drives the column 2 and the vertical rod 7 to rotate around the wind turbine foundation 15, causing the pressure cylinder 9, which is placed on the conical surface of the wind turbine foundation 15, to roll around and flatten the concrete pouring surface of the wind turbine foundation 15. After the concrete pouring surface is flattened and solidified, the fixing plate 1 can be removed and the column 2 can be moved away.

[0026] In one possible implementation, a first sleeve 11 is vertically fixed on the crossbar 6, the vertical rod 7 is inserted into and fixed in the first sleeve 11, a second sleeve 12 is sleeved and fixed on the column 2, and the two ends of the connecting rod 8 are respectively hinged to the first sleeve 11 and the second sleeve 12.

[0027] The vertical rod 7 is vertically inserted into the first sleeve 11 and is fixed by a plug rod. The second sleeve 12 is sleeved on the stand 2 and is fixed by a plug rod. The vertical rod 7 and the second sleeve 12 can be adjusted in height and the overall inclination angle of the connecting rod 8, so that the pressing cylinder 9 can be matched with the conical surface of the fan foundation 15 of different specifications after installation, thereby guaranteeing the flatness of the concrete pouring surface.

[0028] In a possible implementation, the third sleeve 13 is sleeved and fixed on the stand 2, and the horizontal rod 6 is fixed at one end of the stand 2 and the third sleeve 13.

[0029] The third sleeve 13 is sleeved on the upper end of the stand 2 and is fixed by a plug rod. After the fixed plate 1 and the motor 5 are installed at the center of the fan foundation 15, the height of the third sleeve 13 and the horizontal rod 6 can be adjusted up and down to match the different heights of the fan foundation 15, so that the device can run smoothly.

[0030] In a possible implementation, the positioning rod 14 is fixed at the side end of the rotating table 4, the horizontal rod 6 is detachably connected at one end of the rotating table 4 and the positioning rod 14, the stand 2 is detachably connected with the third sleeve 13 and the connecting rod 8, and the horizontal rod 6 is detachably connected with the vertical rod 7.

[0031] The horizontal rod 6 is detachably connected with the positioning rod 14, so that the rotating table 4 and the horizontal rod 6 can be separated. The stand 2 is detachably connected with the third sleeve 13 and the connecting rod 8, so that the stand 2, the horizontal rod 6 and the connecting rod 8 can be separated. The horizontal rod 6 is detachably connected with the vertical rod 7, so that the stand 2, the horizontal rod 6 and the connecting rod 8 can be detached for storage and transportation.

[0032] In a possible implementation, a plurality of positioning rods 14 for connecting the horizontal rod 6 are fixed at the side end of the rotating table 4.

[0033] Each positioning rod 14 can be installed with the horizontal rod 6, and the stand 2 can be connected with the vertical rod 7 and the pressing cylinder 9 through the horizontal rod 6, so that multiple groups of pressing cylinders 9 can simultaneously press and flatten the pouring surface, thereby achieving better and more efficient flattening effect.

[0034] In a possible implementation, the pressing cylinder 9 is hollow inside, is sleeved on the connecting rod 8 and is rotatably connected and sealed with the connecting rod 8, and the side end of the pressing cylinder 9 is provided with a water injection port capable of injecting and discharging water.

[0035] The hollow inside of the pressing cylinder 9 can reduce the burden during transportation. When installed and used, water can be injected into the pressing cylinder 9 through the water injection port to increase the weight of the pressing cylinder 9, and the self-weight pressure of the pressing cylinder 9 can be reasonably adjusted by controlling the amount of water.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
