Description

Technical Field

[0001] The present invention relates to the technical field of casting equipment, and in particular to a fan foundation casting equipment and a casting method based on the Internet of Things. Background Art

[0002] When building a wind turbine foundation pit, pouring the foundation layer and the intermediate foundation layer are key steps. For the foundation layer near the edge of the foundation pit, the existing technology usually uses a chute system for pouring, which is an effective method. However, for the intermediate foundation layer located in the middle of the foundation pit, the pouring process is more complicated. At present, these layers are usually transported to the middle of the foundation pit by conveyor belts, and then dispersed to the surrounding area manually.

[0003] Although this method is feasible, there are several problems. First, it requires a lot of manpower, especially in the case of large wind turbine foundation pits. Second, due to the viscosity of concrete, the process of manually dispersing concrete is inefficient, which prolongs the time of the entire pouring process. In addition, it is difficult to achieve the desired uniformity by relying on manual dispersion of concrete, which may affect the stability and overall quality of the foundation.

[0004] Based on this, in order to further improve the convenience of pouring in the middle of the foundation pit, we proposed a fan foundation pouring equipment and pouring method based on the Internet of Things. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art such as the use of manual dispersion and low efficiency, and to propose a fan foundation casting equipment and casting method based on the Internet of Things.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0013] Furthermore, the scraper is in an L-shaped structure, and a plurality of straight grooves are provided on the bottom bending surface of the scraper. The scraper is connected to the top of the mounting plate through the straight grooves and fasteners.

[0014] Furthermore, the feeding assembly includes a telescopic tube, a motor is fixedly mounted on the rear end of the telescopic tube, and an auger located inside the telescopic tube is fixedly mounted on the shaft end of the motor.

[0015] Furthermore, an electric push rod is fixedly mounted on the rear end pipe section of the telescopic tube, and the axial end of the electric push rod is connected to the front end pipe section of the telescopic tube through a connecting piece.

[0016] Furthermore, the outer diameter of the auger decreases sequentially along the conveying direction of the telescopic tube.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-6An embodiment of the present invention discloses a wind turbine foundation pouring device based on the Internet of Things. Specifically, the pouring device includes a frame 1 on which a control unit 11 is installed. A conveying unit 2 is arranged above the frame 1. The conveying unit 2 described in the present invention adopts a roller driven by a motor and a conveyor belt sleeved on the roller. The conveyor belt rotates to realize the conveyance of concrete materials, thereby completing the pouring of the middle part of the foundation pit.

[0034] The inner side of the frame 1 is movably connected to a slide 4 through a driving member 3, a hopper 5 is fixedly mounted on the end of the slide 4, and a cleaning component 6 is detachably connected to the top of the hopper 5;

[0035] A feeding assembly 7 is rotatably connected to the bottom of the hopper 5 , and a rotating structure 8 is provided between the feeding assembly 7 and the hopper 5 .

[0036] In some implementations, sleeves 12 are fixedly installed on the longitudinal rods on both sides of the bottom of the frame 1 described in the present invention, and the slide 4 is slidably connected to the sleeves 12. Specifically, the slide 4 described in the present invention is configured as a U-shaped frame, wherein the driving member 3 can be configured as an electric push rod, and the electric push rod pushes the slide 4 to move linearly. When it is movable or stored, the hopper 5 can be stored at the bottom of the frame 1 to achieve the purpose of not occupying space.

[0037] In addition, the cleaning assembly 6 in the embodiment of the present invention includes a cross bar 61 fixed on the hopper 5, at least two plug rods 62 are movably inserted above the cross bar 61, a mounting plate 63 is fixedly connected between the top ends of the two plug rods 62, and a scraper 64 in contact with the surface of the conveying unit 2 is fixedly connected to the top of the mounting plate 63;

[0038] A spring 65 is fixedly connected between the mounting plate 63 and the cross bar 61 .

[0039] That is to say, in order to prevent the concrete from adhering to the surface of the conveying unit 2 and falling to the ground during rotation, the present invention adopts a scraper 64 to contact the surface of the conveying unit 2 to scrape off the concrete on the surface of the conveying unit 2, thereby ensuring the cleanliness of the surface of the conveying unit 2. Secondly, by adopting a retractable structure design of an insertion rod 62 and a spring 65, the stability of the contact between the scraper 64 and the surface of the conveying unit 2 can be ensured, thereby improving the scraping effect on the concrete material.

[0040] On the basis of the above-mentioned embodiment, the scraper 64 in the present invention is of an L-shaped structure, and a plurality of straight grooves 66 are provided on the bottom bending surface of the scraper 64. The scraper 64 is connected to the top of the mounting plate 63 via the straight grooves 66 and fasteners. Specifically, the fasteners described in this embodiment are bolts, and the bolts are located in the straight grooves 66. That is, the front and rear positions of the scraper 64 can be adjusted by adopting the structural design of the straight grooves 66 in the present invention. In addition, the connection and disassembly operations of the scraper 64 can be completed by installing and disassembling the bolts, so as to improve the convenience of maintenance and cleaning of the scraper 64.

[0041] Furthermore, the feeding assembly 7 in this embodiment includes a telescopic tube 71, which is composed of a plurality of tube sections that are sequentially sleeved. Of course, a sealing structure, such as a sealing ring, may be provided between each two tube sections to avoid the problem of concrete leakage. This method is a conventional method used by technicians in the field and will not be described in detail here.

[0042] Specifically, a motor 72 is fixedly installed on the tail end of the telescopic tube 71, and an auger 73 located inside the telescopic tube 71 is fixedly installed on the shaft end of the motor 72. The motor 72 drives the auger 73 to rotate to push the concrete material inside the telescopic tube 71 forward for transportation, so as to avoid the accumulation of concrete material inside the telescopic tube 71. Of course, the telescopic tube 71 described in the present invention can be connected to the hopper 5 in an inclined manner to further improve the convenience of sliding out the concrete material.

[0043] On the basis of the above-mentioned embodiment, an electric push rod 74 is fixedly installed on the tail end pipe section of the telescopic tube 71 in this embodiment, and the axial end of the electric push rod 74 is connected to the front end pipe section of the telescopic tube 71 through a connecting piece, that is, the electric push rod 74 is used to control the telescopic length of the entire telescopic tube 71 in the present invention, so that the feeding range of the concrete material can be changed. After the circumferential position of the telescopic tube 71 is adjusted in coordination with the rotating structure 8, the feeding radius can be changed within the circumferential range to ensure that when pouring in the middle of the foundation pit, a large range of material feeding is achieved, and there is no need for manual material shifting, thereby improving the convenience of operation.

[0044] It should be noted that the outer diameter of the auger 73 described in the embodiment of the present invention decreases successively along the conveying direction of the telescopic tube 71. Specifically, the length of the auger 73 described in the present invention is smaller than the length of the pipe section at the tail end of the telescopic tube 71. The structural design with reduced diameter can ensure stable pushing of materials while avoiding position interference with other pipe sections during storage due to the smaller diameter of the tail end of the auger 73.

[0045] In some embodiments, the rotating structure 8 of the present invention includes a discharge pipe 81 installed at the bottom of the hopper 5, and a feed pipe 82 is connected to the tail end of the telescopic tube 71. The discharge pipe 81 in this embodiment is fixedly connected to the hopper 5, and the feed pipe 82 is fixedly connected to the telescopic tube 71;

[0046] The end of the feed pipe 82 is sleeved on the outside of the discharge pipe 81 and rotatably connected. Of course, a sealing structure can also be set at the rotational connection between the two. A worm gear 83 is fixedly installed on the outside of the top end of the feed pipe 82, and a drive motor 84 is fixedly connected to the side of the slide 4. A worm 85 meshing with the worm gear 83 is fixedly installed on the shaft end of the drive motor 84. When it is necessary to adjust the circumferential position of the feeding of the telescopic tube 71 during operation, the worm 85 is driven to rotate by the drive motor 84. Since the worm 85 is meshed with the worm gear 83 for transmission, the feed pipe 82 is driven to rotate. Since the feed pipe 82 is fixedly connected to the telescopic tube 71, the circumferential position of the telescopic tube 71 can be driven and controlled at this time.

[0047] Preferably, in order to realize remote control of each action drive component in the present invention, the drive component 3, motor 72, electric push rod 74 and drive motor 84 in this embodiment are all electrically connected to the control unit 11, and the control unit 11 is connected to the cloud server through a wireless module. Of course, the wireless module can adopt a LORA module, a Bluetooth module or a WIFI module, and can be connected to the server through a terminal such as a mobile phone to realize control of each drive component, so as to realize remote control of the casting equipment and improve the convenience and safety of operation.

[0048] In addition, the present invention also proposes a method for pouring a wind turbine foundation based on the Internet of Things, using the above-mentioned equipment, and the specific method includes the following steps:

[0049] The frame 1 is installed at a predetermined position on the side of the foundation pit, and the driving member 3 controls the slide 4 to move out, so that the hopper 5 moves to the bottom of the tail end of the conveying unit 2;

[0050] The concrete is placed on the conveying unit 2 for conveying, and the concrete falls into the hopper 5 and falls into the feeding assembly 7 to be discharged outward;

[0051] The rotating angle of the feeding assembly 7 is controlled by the rotating structure 8, and the telescopic length of the feeding assembly 7 is controlled to realize circular pouring in the middle of the foundation pit until the pouring operation in the middle of the foundation pit is completed.

[0052] In summary, the present invention adopts the design of the cleaning component 6 to clean the surface of the conveying unit 2, which can prevent the conveying unit 2 from rotating and causing concrete to drip onto the ground. Secondly, the telescopic feeding component 7 and the rotating structure 8 that controls the circumferential rotation of the feeding component 7 are designed. When pouring the middle part of the foundation pit, the circumferential position of the telescopic tube 71 is adjusted by the rotating structure 8, and the feeding radius can be changed within the circumferential range to ensure that when pouring in the middle part of the foundation pit, a large range of material feeding is achieved, without the need for manual material selection, thereby improving the convenience of operation.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
