[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figures 1-5 As shown, a wind turbine foundation concrete pouring equipment for a wind farm includes a support frame 1. A conveying plate 2 is slidably connected inside the support frame 1. A feed hopper 3 is fixedly connected to the top of the support frame 1. A conveying assembly 4 is installed on the surface of the support frame 1. The conveying assembly 4 includes two support legs 41 of different lengths and a lead screw 45. The two support legs 41 are respectively fixedly installed on both sides of the support frame 1. A mounting base 42 is fixedly connected to the side wall of the support leg 41. An electric push rod 43 is fixedly connected to the surface of the mounting base 42. A support block 44 is rotatably connected to the drive end of the electric push rod 43. The lead screw 45 is rotatably installed on the bottom of the conveying plate 2 and is threadedly connected to the support frame 1.
[0024] Specifically, the support frame 1 is tilted and supported by the support leg 41, and the lower end of the support frame 1 is moved to the center of the annular foundation pit, while the higher end of the support frame 1 is located on the outside of the foundation pit. During pouring, the concrete truck pours concrete into the feed hopper 3, and then the concrete falls from the feed hopper 3 onto the conveyor plate 2, and finally slides into the foundation pit from the conveyor plate 2. By rotating the connecting screw 45, the conveyor plate 2 is moved and its position is adjusted, allowing the concrete to be poured into different locations, reducing the need for workers to scatter the concrete around, thus increasing the flexibility of the pouring process. After the partial pouring of the foundation pit is completed, the electric push rod 43 extends and drives the support block 44 to descend and touch the ground, thereby raising the shorter support leg 41 and suspending it in the air. By pushing the support frame 1 to rotate around the support block 44, the position of the support frame 1 can be adjusted in a ring shape for pouring, which can increase the pouring area and improve the pouring efficiency.
[0025] A servo motor 5 is fixedly connected to the side wall of the conveyor plate 2, and the drive end of the servo motor 5 is fixedly connected to one end of the lead screw 45.
[0026] Specifically, the servo motor 5 drives the lead screw 45 to rotate, and the rotation of the lead screw 45 causes the conveyor plate 2 to slide laterally along the support frame 1, which facilitates the adjustment of the pouring position.
[0027] The bottom of the support leg 41 is symmetrically fixed with movable wheels 6, and the upper side wall of the support leg 41 is fixedly connected with reinforcing ribs 7. The other end of the reinforcing ribs 7 is fixedly connected to the support frame 1.
[0028] Specifically, the movable wheel 6 facilitates the movement of the device, and the reinforcing rib 7 increases the strength of the supporting leg 41.
[0029] The conveyor plate 2 includes a base plate 21 and a flow plate 22. The opposite ends of the base plate 21 and the flow plate 22 are rotatably connected by a shaft. The flow plate 22 is located below the feed hopper 3. The flow plate 22 is U-shaped and has an opening on one side. The top of the base plate 21 is rotatably connected to a spring telescopic rod 23 by a shaft. The top end of the spring telescopic rod 23 is rotatably connected to the bottom end of the flow plate 22 by a shaft. A vibrator 8 is fixedly connected to the bottom of the flow plate 22.
[0030] Specifically, the base plate 21 is used to slide and connect with the support frame 1, and the flow plate 22 is used to receive the concrete falling from the feed hopper 3. The flow plate 22 is elastically supported by the spring telescopic rod 23, so that the flow plate 22 is kept tilted to facilitate the concrete to slide down. The vibration of the flow plate 22 is caused by the operation of the vibrator 8, which can assist the concrete to flow downward, thereby improving the concrete pouring efficiency.
[0031] A scraper 24 is slidably connected to the top of the flow plate 22, and a connecting block 25 is rotatably connected to the side wall of the scraper 24 via a shaft. The connecting block 25 is slidably connected to the feed hopper 3.
[0032] Specifically, when the flow plate 22 vibrates, it causes the connecting block 25 to slide along the feed hopper 3. Then, when the conveying plate 2 slides to adjust the conveying position, the scraper 24 can scrape away the residual concrete in the area where the conveying plate 2 moves upward through the scraper 24, thereby reducing concrete waste.
[0033] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Furthermore, appropriate controllers should be selected and electrically connected to the electric push rod 43, servo motor 5, and vibrator 8 according to the actual situation to meet control requirements. Specific connections and control sequences should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.
[0034] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
[0035] Working principle: During pouring, the concrete mixer truck pours concrete into the feed hopper 3, which then drops it onto the conveyor plate 2. Finally, the conveyor plate 2 slides into the foundation pit. By rotating the connecting screw 45, the conveyor plate 2 can be moved and its position adjusted. Concrete can be poured into different locations, reducing the need for workers to scatter concrete around, thus increasing the flexibility of pouring. After the local pouring of the foundation pit is completed, the electric push rod 43 extends and lowers the support block 44 to touch the ground, thereby raising the shorter support leg 41 and suspending it in the air. By pushing the support frame 1 to rotate around the support block 44, the position of the support frame 1 can be adjusted in a ring for pouring, which can increase the pouring area and improve pouring efficiency.
[0036] The flow plate 22 is elastically supported by the spring telescopic rod 23, which keeps the flow plate 22 tilted to facilitate the concrete to slide down. The vibration of the flow plate 22 caused by the operation of the vibrator 8 can assist the concrete to flow downward, thereby improving the concrete pouring efficiency.
