Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, specifically a large-volume concrete curing device for wind turbine foundations. Background Technology

[0002] Concrete curing is a crucial process in the initial stage after pouring, where humidity and temperature are controlled to ensure that the cement and water undergo a full hydration reaction, thereby hardening and reaching the designed strength. Cement needs sufficient moisture to complete hardening; water shortage will lead to a decrease in strength, and early dehydration can easily cause drying shrinkage cracks, affecting durability. Uniform temperature and humidity can reduce structural problems caused by uneven shrinkage.

[0003] Regarding the above and existing related technologies: During the construction of wind turbines, it is necessary to pour large-volume concrete on the foundation. Since large-volume concrete is prone to moisture condensation during hardening, it is necessary to use water spray pipes to spray the concrete. However, since most spray pipes need to be held in hand, prolonged spraying can easily cause arm discomfort and affect spraying efficiency. Therefore, to address the above problems, a large-volume concrete curing device for wind turbine foundations is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A large-volume concrete curing device for wind turbine foundations, comprising a vehicle body, a spray pipe, and a support device. A push handle is fixedly connected to the upper surface of the vehicle body, and the spray pipe is located directly above the vehicle body. The support device is set on the upper surface of the vehicle body and includes a rotating rod. The inner wall of the rotating rod is rotatably connected to the surface of the vehicle body, and an adjusting rod is rotatably connected to the surface of the rotating rod. Multiple fixing rings are inserted into the inner wall of the adjusting rod, and a positioning pin is threadedly connected to the inner wall of the adjusting rod and the fixing rings. The fixing rings are fitted onto the surface of the spray pipe. The adjusting rod is then pushed to rotate on the surface of the rotating rod, and the rotating rod is then pushed to rotate on the surface of the vehicle body. After the spray pipe is fixed in a suitable position, water is sprayed onto the concrete through the spray pipe. By setting the rotating rod, adjusting rod, fixing rings, and positioning pins, the spray pipe can be fixed, and the angle of the spray pipe can be easily adjusted.

[0006] Preferably, the surface of the adjusting rod is provided with multiple storage slots, and the fixing ring is inserted into the inner surface of two storage slots of the adjusting rod. When the fixing ring moves, the fixing ring will be inserted into the inner wall of the storage slot. The fixing ring can be stored by providing storage slots.

After the rotating rod rotates to a suitable angle, the fixing pins are rotated to the inner walls of the two fixing blocks and the rotating rod. By setting the fixing blocks and fixing pins, the angle of the rotating rod can be limited.

[0008] Preferably, the inner walls of the rotating rod and the adjusting rod are threaded with a limiting pin. After the adjusting rod is rotated to a suitable angle, the limiting pin is rotated to the inner wall of the rotating rod and the adjusting rod, and the limiting pin can limit the angle of the adjusting rod.

[0009] Preferably, the surface of the adjusting rod is provided with multiple limiting holes, and the surface of the limiting pin is threadedly connected to the inner wall of the limiting hole of the adjusting rod. When the limiting pin rotates, the limiting pin rotates to the inner wall of the limiting hole, and the opening of the limiting hole can accommodate the limiting pin.

[0010] Preferably, the side wall of the rotating rod is provided with multiple limiting devices. Each limiting device includes a placement block, the side wall of which is fixedly connected to the side wall of the rotating rod. A main wheel is rotatably connected to the surface of the placement block, and the main wheel is located on the surface of the nozzle. A moving block is slidably connected to the surface of the placement block, and a secondary wheel is rotatably connected to the side wall of the moving block, and the secondary wheel is located on the surface of the nozzle. The moving block drives the secondary wheel to move, and the secondary wheel fits against the nozzle. When the nozzle moves, it drives the main wheel and the secondary wheel to rotate. By setting the placement block, the main wheel, the moving block, and the secondary wheel, the position of the nozzle can be limited.

[0011] Preferably, the surface of the movable block is provided with a sliding hole, and the inner wall of the sliding hole of the movable block is slidably connected to the surface of the placement block. When the movable block moves, the movable block slides on the surface of the placement block through the sliding hole.

[0012] Preferably, the inner walls of the moving block and the placement block are threaded with bolts. After the moving block moves to a suitable position, the bolts are rotated to the inner walls of the moving block and the placement block. The bolts can limit the position of the moving block.

[0015] 2. After the nozzle is installed, the other part of the nozzle is attached to the main wheel. Then, the moving block is pushed to drive the auxiliary wheel to move. The auxiliary wheel is attached to the nozzle. When the moving block moves, it will slide on the surface of the placement block. Then, the bolt is rotated to the inner wall of the moving block and the placement block. When the nozzle moves, the nozzle moves on the surface of the main wheel and the auxiliary wheel. The main wheel and the auxiliary wheel will rotate. By setting the entire device, the position of the nozzle can be restricted, reducing the situation of the nozzle moving randomly.
