Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wind power tower concrete construction, in particular to a wind power tower concrete pumping device. Background Art
[0002] A wind turbine tower is the main component of a wind turbine. Traditional wind turbine towers are made of metal. However, due to the tower's height and the large amount of material used, concrete casting is a popular method for wind turbine towers, offering both low cost and high structural stability. Concrete casting is not only economical but also environmentally friendly and has gradually become a mainstream method for wind turbine tower production.
[0003] Specifically, during the construction process, operators pre-assemble the wind turbine tower formwork, then attach the steel cage, and finally pour concrete along the ring-shaped steel cage using a concrete pump. Specifically, during construction, operators hold a rubber hose attached to the concrete pump and continuously pump concrete into the steel cage through the rubber hose.
[0004] To ensure uniform concrete filling of the steel cage, operators need to constantly swing the rubber hose to release the concrete. However, in practice, since the rubber hose contains the concrete being released, swinging the hose is quite laborious, often requiring multiple operators to coordinate the swinging. However, the single cylindrical rubber hose is not only bulky due to the concrete, but also prevents construction workers from coordinating the swinging of the hose to facilitate the release of the concrete.
[0005] Therefore, in actual working process, it is very strenuous to assist the swinging rubber hose (swinging not only achieves uniform material spreading, but also assists the discharge of concrete with poor fluidity to avoid blockage and slow discharge). As a result, it is difficult to spread the concrete in a relatively high and labor-saving manner during the concrete pumping operation.
[0006] At the same time, during the material feeding and pumping process, when the concrete is not shaken in time and the fluidity of the concrete is poor, when it encounters a small gap in the steel cage structure, the concrete is easily accumulated on the steel cage and cannot fall into the steel cage structure through the gap.

[0042] Example 1
[0043] like Figure 1-6 As shown, a wind turbine tower concrete pumping device includes a pumping rubber hose 1 installed on a concrete pump. Specifically, the concrete pump is a concrete pump body of an existing concrete pump. According to the existing method, the flange on the pumping rubber hose 1 is installed on the discharge port of the concrete pump.
[0044] The above-mentioned pumping rubber tube 1 is equipped with a swing mechanism for swinging and unloading. According to the existing method, the above-mentioned swing mechanism includes a ring body 4 sleeved on the pumping rubber tube 1, and the ring body 4 is concentrically provided with an outer swing ring rod 2, and the outer swing ring rod 2 and the ring body 4 are assembled and connected by a number of swing structures 3.
[0045] Specifically, the outer rocking ring rod 2 and the collar body 4 are assembled and connected via four rocking structures 3 distributed in a ring array.
[0046] Specifically, the rocking structure 3 includes a rectangular fixed protrusion 31 fixedly connected to the inner wall of the ring body 4, and a sliding opening is opened on the fixed protrusion 31, and a rocking slide 33 is slidably connected in the sliding opening. The rocking slide 33 is fixedly installed on the ring body 4 through an installation screw structure; the two ends of the rocking slide 33 pass through both sides of the sliding opening.
[0047] At the same time, a plurality of springs 32 are fixedly connected inside the rocking slide plate 33 , and the springs 32 are fixedly connected to the inner side wall of the sliding opening.
[0048] Two curved handles 21 are fixedly mounted on the outer sidewall of the outer swing ring 2. Several connecting rods are fixedly connected to the outer sidewall of the outer swing ring 2, and the outer ends of these connecting rods are fixedly connected to connecting bolts; the connecting bolts are fastened to the curved handles 21. End baffles 331 are fixedly connected to each end of the swing slide 33.
[0049] Specifically, a threaded connection seat 341 is fixedly connected to the outer wall of the collar body 4 , and the inner end of the mounting screw 34 is threadedly connected to the threaded connection seat 341 ; the outer end of the mounting screw 34 is threadedly connected to the rocking slide 33 .
[0050] During the working process, when the concrete pump is pumping concrete, the operator holds the curved handle 21 in a cooperative state. When the operator holds the curved handle 21 and shakes the pumping rubber tube 1, such as when the operator swings it back and forth, the swinging slide 33 located in the front and back directions slides back and forth on the sliding mouth of the fixed protrusion 31. During the back and forth sliding process, the spring 32 expands and contracts. At this time, the swinging slide 33 located in the left and right directions swings left and right in its sliding mouth. During the left and right swinging process, the swinging slide 33 is fixedly connected to the end baffle 331 at both ends. Therefore, under the isolation of the baffle 331, it is ensured that the swinging slide 33 will not separate from the fixed protrusion 31.
[0051] The above method is used to ensure that the pumping rubber tube 1 can be fully swung to discharge the concrete during the pouring process of pumping concrete. Specifically, the above method can fully shake the pumping rubber tube 1 in a simple and flexible manner, thereby effectively ensuring that the concrete can be fully discharged into the steel cage.
[0052] Example 2
[0053] like Figure 1-6 As shown, this embodiment builds on the existing structure of Example 1, with several concrete scraping mechanisms installed at the bottom of the outer swing ring 2. Specifically, during concrete pumping, concrete that falls above the rebar cage is scraped by the concrete scraping mechanisms and then falls into the cage through the gaps in the rebar cage.
[0054] Specifically, the concrete scraping mechanism includes a mounting seat 54 fixedly mounted at the bottom of the outer swing ring rod 2, the bottom of the mounting seat 54 is fixedly assembled and connected with a telescopic plate structure with adjustable length; the bottom of the telescopic plate structure is installed with a plow-shaped scraper 51.
[0055] The specific structure of the telescopic plate structure is as follows:
[0056] The telescopic plate structure includes a fixed long plate 53 fixedly mounted on a mounting seat 54, and the fixed long plate 53 is sleeved with a sleeve body 52; the sleeve body 52 is threadedly connected with a locking screw 541 for locking and positioning the fixed long plate 53 (correspondingly, the fixed long plate 53 is provided with several threaded holes of different heights, so that after loosening the locking screw 541, the locking screw 541 can be threadedly connected to the threaded holes at different positions).
[0057] At the same time, a hinge port is provided on the plow-shaped scraper 51, and both sides of the bottom of the sleeve body 52 are fixedly connected with hinge screws 511 hinged on the plow-shaped scraper 51, and the outer end of the hinge screw 511 is threadedly connected with a locking nut.
[0058] During operation, the operator loosens the locking screw 541 and fastens the locking screw 541 to the threaded holes at different positions and heights on the fixed long plate 53 , and locks the screw to maintain the position.
[0059] At this time, the operator swings the entire device to ensure that during the concrete feeding process, the concrete accumulated on the steel cage is scraped by the plow-shaped scraper 51 and fully falls into the steel cage. (In particular, during the process of pumping the concrete into the steel cage, the accumulated concrete falls through the gaps on the steel cage, which is too small to fall into the cage, especially when the pumping speed is too high.) This technical means effectively solves the technical problem of concrete not falling into the steel cage.
[0060] In the above structure, the operator loosens the locking nut, turns over the plow-shaped scraper 51, and then tightens the locking nut.
[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
