Description

Technical Field

[0001] This utility model relates to the field of wind power tower construction technology, specifically to a hoisting device for anchor bolt cages of power collection lines in the foundation of a mountain wind power tower. Background Technology

[0002] Wind power equipment consists of a wind turbine, a generator, and a tower. Based on the direction of the main shaft, it is divided into horizontal and vertical shafts. The number of blades is mainly three-bladed. The transmission methods include gearbox type and direct drive type. The design of wind turbine towers must be based on specific working conditions (such as wind speed, terrain, and equipment parameters). The core is to balance structural strength and material cost.

[0003] Regarding the above and existing related technologies: During the construction of wind turbine towers, anchor bolt cages are frequently used. These cages need to be hoisted into the pre-erected column formwork in the foundation pit. Traditional installation requires the use of cranes, but due to the complex location environment of wind turbine towers, using cranes can lead to inconvenience in handling and affect hoisting efficiency. Therefore, to address these issues, a hoisting device for anchor bolt cages of power collection lines in mountain wind turbine tower 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: The anchor bolt cage hoisting device for the collection line in the mountain wind power tower foundation of this utility model includes two support rods and a hoisting device. The inner walls of the two support rods are provided with threaded rods, and two positioning rods are inserted into the inner walls of the support rods. The hoisting device is set directly above the two threaded rods. The hoisting device includes two rotating blocks. The inner walls of the rotating blocks and the surfaces of the threaded rods are rotatably connected. Hoisting rods are inserted into the inner surfaces of the two rotating blocks. Two bolts are provided on the inner walls of the rotating blocks and the hoisting rods. A moving block is slidably connected to the surface of the hoisting rod. A hook is fixedly connected to the bottom end of the moving block. The hoisting rod drives the rotating block to rotate. The rotating block rotates on the surface of the threaded rod, and then the anchor bolt cage is hung on the hook. Then, the moving block is pushed to move the moving block on the surface of the hoisting rod. The moving block drives the anchor bolt cage on the hook to move. By setting up the entire device, the anchor bolt cage can be hoisted conveniently.

[0006] Preferably, the inner surface of the movable block is rotatably connected to two rollers, which are located on the surface of the hoisting rod. The rollers roll on the surface of the hoisting rod. By setting the rollers, the movable block can be supported, and the movable block can also be moved to a convenient position.

[0007] Preferably, a pull rope is fixedly connected to the side wall of the movable block. When it is necessary to adjust the position of the movable block, the pull rope is pulled to move the movable block. The position of the movable block can be easily adjusted by setting the pull rope.

[0008] Preferably, a support block is fixedly connected to the upper surface of the rotating block, and a support wheel is rotatably connected to the surface of the support block. The support wheel is located on the surface of the pull rope and rotates on the surface of the support block. By setting the support block and the support wheel, the pull rope can be supported.

[0009] Preferably, the surface of the rotating block has a through hole, and the hoisting rod is inserted into the inner wall of the through hole of the rotating block. When the hoisting rod moves, the hoisting rod is inserted into the inner wall of the through hole, and the opening of the through hole can facilitate the storage of the hoisting rod.

[0010] Preferably, the surface of the support rod is provided with a support device, the support device including a fixing block, the side wall of the fixing block being fixedly connected to the surface of the support rod, a rotating rod being rotatably connected to the surface of the fixing block, and rotating columns being rotatably connected to both sides of the rotating rod. A limiting rod is inserted into the inner wall of the rotating column. The rotating column is rotated to a suitable angle, and then the limiting rod is inserted into the rotating column and the inner surface of the soil. By setting the fixing block, rotating rod, rotating column and limiting rod, the support rod can be supported.

[0011] Preferably, multiple reinforcing columns are fixedly connected to the surface of the rotating rod. When the rotating rod is subjected to force, the force is transmitted to the reinforcing columns, which can increase the strength of the rotating rod.

[0012] The advantages of this utility model are:

[0013] 1. When it is necessary to lift the anchor bolt cage, the support rod is fixed in a suitable position by the positioning rod. Then, the threaded rod is rotated to make the threaded rod rotate on the inner wall of the support rod. The height of the rotating block is adjusted by the threaded rod. Then, the rotating block is pushed to rotate to a suitable angle. Then, the lifting rod is inserted into the inner surface of the through hole of the two rotating blocks. Then, the lifting rod is fixed to the inner wall of the rotating block with bolts. When lifting, the anchor bolt cage is hung on the hook. Then, the pull rope is pulled to make the pull rope move the moving block. The pull rope moves on the surface of the support wheel on the support block. The support wheel rolls on the surface of the support block. When the moving block moves, it will drive the roller to roll on the surface of the lifting rod. The moving block will also drive the anchor bolt cage on the hook to move. When the anchor bolt cage is moved to the installation position, the lifting rope is tied to other objects. By setting up the whole device, the anchor bolt cage can be lifted and transported conveniently. At the same time, the lifting device can be moved easily, reducing the impact of terrain on the transport, thereby increasing the lifting efficiency.

[0014] 2. After the support rod is set up, the rotating rod is pushed to rotate on the surface of the fixed block. When the rotating rod rotates, the rotating column rotates so that the rotating column touches the ground. Then, the limiting rod is inserted into the rotating column and the inner surface of the soil. When the rotating rod is under force, the rotating rod will transmit the force to the reinforcing column. By setting up the whole device, the support rod can be supported, reducing the situation of the support rod moving randomly under force. Attached Figure Description

The surface of the device is slidably connected to a movable block 43, and the bottom end of the movable block 43 is fixedly connected to a hook 44. During operation, the support rod 1 is fixed in a suitable position, and then the two threaded rods 2 are adjusted to tilt the hoisting rod 42. The hoisting rod 42 will drive the rotating block 41 to rotate. The rotating block 41 rotates on the surface of the threaded rod 2. Then, the anchor bolt cage is hung on the hook 44, and then the movable block 43 is pushed to move on the surface of the hoisting rod 42. The movable block 43 drives the anchor bolt cage on the hook 44 to move. By setting up the entire device, the anchor bolt cage can be easily hoisted.

[0024] Two rollers 45 are rotatably connected to the inner surface of the movable block 43, and the two rollers 45 are located on the surface of the hoisting rod 42. During operation, the movable block 43 drives the rollers 45 to rotate, and the rollers 45 roll on the surface of the hoisting rod 42. By setting the rollers 45, the movable block 43 can be supported, and the movable block 43 can also be moved to a convenient position.

[0025] A pull rope 46 is fixedly connected to the side wall of the movable block 43; during operation, pulling the pull rope 46 causes the movable block 43 to move, and the position of the movable block 43 can be easily adjusted by setting the pull rope 46.

[0026] A support block 47 is fixedly connected to the upper surface of the rotating block 41, and a support wheel 48 is rotatably connected to the surface of the support block 47. The support wheel 48 is located on the surface of the pull rope 46. During operation, the pull rope 46 moves on the surface of the support wheel 48, and the support wheel 48 rotates on the surface of the support block 47. By setting the support block 47 and the support wheel 48, the pull rope 46 can be supported.

[0027] The rotating block 41 has a through hole 49 on its surface, and the hoisting rod 42 is inserted into the inner wall of the through hole 49 of the rotating block 41. During operation, the hoisting rod 42 is inserted into the inner wall of the through hole 49, and the opening of the through hole 49 can facilitate the storage of the hoisting rod 42.

[0028] The surface of the support rod 1 is provided with a support device 5. The support device 5 includes a fixing block 51. The side wall of the fixing block 51 is fixedly connected to the surface of the support rod 1. A rotating rod 52 is rotatably connected to the surface of the fixing block 51. Rotating columns 53 are rotatably connected to both sides of the rotating rod 52. A limiting rod 54 is inserted into the inner wall of the rotating column 53. During operation, the rotating rod 52 is rotated to rotate on the surface of the fixing block 51.

[0030] Working principle: When hoisting the anchor bolt cage, the support rod 1 is fixed in a suitable position by the positioning rod 3. Then, the threaded rod 2 is rotated to make it rotate on the inner wall of the support rod 1. The threaded rod 2 adjusts the height of the rotating block 41, and then the rotating block 41 is pushed to rotate to a suitable angle. The hoisting rod 42 is then inserted into the inner surface of the through holes 49 of the two rotating blocks 41, and then bolts are used to fix the hoisting rod 42 to the inner wall of the rotating block 41. During hoisting, the anchor bolt cage is hung on the hook 44, and then the pull rope 46 is pulled to make the pull rope 46 drive the moving block 43 to move. The pull rope 46 moves on the surface of the support wheel 48 on the support block 47, and the support wheel 48 rolls on the surface of the support block 47. When the moving block 43 moves, it will drive the roller 45 to roll on the surface of the hoisting rod 42. The moving block 43 will also drive the anchor bolt cage on the hook 44 to move. When the anchor bolt cage moves to the installation position, the lifting rope is tied to other objects. By setting up the whole device, the anchor bolt cage can be lifted and transported, and the lifting device 4 can be moved easily, reducing the impact of terrain on the transportation and thus increasing the lifting efficiency. After the support rod 1 is set up, push the rotating rod 52 to make the rotating rod 52 rotate on the surface of the fixed block 51. When the rotating rod 52 rotates, it rotates the rotating column 53, so that the rotating column 53 is pressed against the ground. Then, the limiting rod 54 is inserted into the rotating column 53 and the inner surface of the soil. When the rotating rod 52 is under force, the rotating rod 52 will transmit the force to the reinforcing column 55. By setting up the whole device, the support rod 1 can be supported, reducing the situation of the support rod 1 moving randomly under force.
