Description

Technical Field

[0001] The utility model relates to the field of wind power tower assembly, in particular to an auxiliary device for large合拢 assembly of wind power towers. Background Technique

[0002] With the continuous growth of the global demand for clean energy, wind power generation, as a renewable and pollution-free energy acquisition method, has developed rapidly. As an important supporting structure of the wind power generation unit, the quality and stability of the wind power tower directly affect the operation efficiency and safety of the entire wind power generation system. In the manufacturing process of the wind power tower, large合拢 assembly is a key link. In this process, the pre-manufactured tower barrel segments are connected and assembled at the construction site to form a tower body structure that can withstand wind force and various environmental loads.

[0003] Since wind power towers are usually large in volume and heavy in weight, hoisting and adjustment are required during assembly. All the equipment used in this process can be collectively referred to as such. Not only is the efficiency low, but there are also potential safety hazards. In addition, there are various auxiliary devices for large合拢 assembly of wind power towers, including support equipment, hoisting equipment, transfer equipment, etc. Among them, the hoisting equipment consists of a boom, a hoisting mechanism, a slewing mechanism, a power system, an operating system, and components such as an electrical system. Operators control the actions of the crane through these devices. At the same time, most of the booms are designed as "C"-shaped frames. When in use, the boom will be inserted into the wind power tower barrel to be processed to hoist the tower barrel.

[0004] However, the above-mentioned auxiliary device for large合拢 assembly of wind power towers still has certain problems when in use. For example, most of the booms in the current auxiliary device are simply designed as "C"-shaped frames, and only rely on friction and the weight of the tower barrel to ensure the stability and fixation effect of the tower barrel on the boom. However, in order to facilitate the movement and angle change of the boom, the top of the boom is mostly connected to the hoisting mechanism through a hook, which causes the boom to shake during movement. When in use, workers will use a pulling rope to pull the boom to assist in positioning it, but it still shakes. This will increase the pressure on the boom when hoisting the tower barrel, and it is easy to reduce the service life of the boom and cause safety accidents such as damage over a long time. Therefore, it is urgently necessary to improve on the basis of the existing auxiliary device for large合拢 assembly of wind power towers. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide an auxiliary device for large合拢 assembly of wind power towers to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary device for large-scale closure and assembly of a wind power tower, comprising a lifting arm, a clamping plate for reinforcing the tower tube is arranged inside the lifting arm, and a limiting rod slidably connected to the lifting arm is installed on the top of the clamping plate, and a threaded barrel rotatably connected to the clamping plate is installed on the inner thread of the top of the lifting arm, a transmission block for driving the threaded barrel to rotate is rotatably installed inside the lifting arm, and a transmission assembly for driving the transmission block to rotate is arranged inside the lifting arm, and a rope pulley corresponding to the transmission assembly is arranged on the outer side of the top of the lifting arm to drive the transmission assembly to operate, a pulley is wound around the rope pulley, and the two ends of the pull rope are respectively a main rope end and a secondary rope end, and a connecting plate is slidably installed on the main rope end, and the end of the connecting plate is fixedly connected to the secondary rope end.

[0008] Furthermore, two groups of the limiting rods are symmetrically installed on the top of the clamping plate, and the length of the limiting rods is greater than the length of the threaded barrel.

[0009] By adopting the above technical solution, the sliding stability of the clamping plate is further ensured, and at the same time, the clamping plate is prevented from being separated from the lifting arm.

[0010] Furthermore, the transmission assembly consists of a first bevel gear, a second bevel gear and a gear transmission box, a first bevel gear fixedly connected to the top of the transmission block is rotatably installed inside the top of the boom, a gear transmission box connected to the pulley is fixedly installed on the top of the boom, and a second bevel gear meshingly connected to the first bevel gear is installed at the output end of the gear transmission box.

[0011] By adopting the above technical solution, it is ensured that the transmission block can smoothly obtain the power for rotation, and it is ensured that the clamping plate can smoothly perform the lifting and lowering movement.

[0012] Furthermore, the transmission block is designed as a rectangular block, and a sliding groove corresponding to the transmission block is opened in the threaded barrel.

[0013] By adopting the above technical solution, it is ensured that the threaded barrel lifting motion pair transmission block can still drive the threaded barrel to rotate.

[0014] Furthermore, a ball head is fixedly mounted on the end of the main rope, and the diameter of the ball head is larger than the diameter of the main rope end.

[0015] By adopting the above technical solution, it is ensured that the main rope end and the auxiliary rope end can be in a connected state for a long time.

[0016] Furthermore, the rope wheel is provided with a plurality of turns of the rope wheel, and the number of turns of the rope wheel on the rope wheel is at least four.

[0017] By adopting the above technical solution, it is ensured that the rope wheel can rotate smoothly when the main rope end or the auxiliary rope end is pulled.

[0018] Furthermore, two groups of limiting plates for limiting the pull rope are symmetrically installed on the outer wall of the gear transmission box, and limiting wheels that are in contact with the outer wall of the pull rope are rotatably installed on the inner walls of the limiting plates.

[0019] By adopting the above technical solution, the pull rope will be restricted by the limiting wheel to prevent the main rope end and the auxiliary rope end from interfering with each other.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] The utility model is provided with a clamping plate, a limiting rod, a threaded cylinder, a transmission component, a rope pulley and a pull rope, so that the user can squeeze and fix the tower by pulling the pull rope, thereby improving the fixation of the tower on the crane arm, ensuring the safety of the tower during transportation, and further reducing the occurrence of safety accidents during the large closure of the tower, making the device more suitable for wide promotion and use.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] An auxiliary device for large folding and assembly of wind power towers, such as Figure 1-Figure 6 As shown, it includes a boom 1, a clamping plate 2 for reinforcing the tower is arranged inside the boom 1, and a limiting rod 3 slidably connected to the boom 1 is installed on the top of the clamping plate 2, and the clamping plate 2 is slidably connected to the boom 1 through the limiting rod 3, so as to ensure the stability of the clamping plate 2 when sliding;

[0032] Because the top of the boom 1 is internally threaded with a threaded barrel 4 rotatably connected to the clamping plate 2, when the threaded barrel 4 rotates, it will drive the clamping plate 2 to move up and down in the boom 1, thereby ensuring that the clamping plate 2 can smoothly clamp the tower;

[0033] Furthermore, a transmission block 5 for driving the threaded barrel 4 to rotate is rotatably installed in the boom 1, so that the transmission block 5 will drive the threaded barrel 4 to rotate synchronously when rotating. In addition, a transmission assembly for driving the transmission block 5 to rotate is provided in the boom 1, and a rope wheel 9 corresponding to the transmission assembly is provided on the outer side of the top of the boom 1 to drive the transmission assembly to operate. When the transmission assembly operates, the transmission block 5 will be driven to start operating, ensuring that the transmission block 5 can smoothly drive the threaded barrel 4 to rotate;

[0034] Furthermore, a pull rope 10 is wound around the rope wheel 9, and the two ends of the pull rope 10 are respectively a main rope end 101 and a secondary rope end 102. Since the main rope end 101 and the secondary rope end 102 are respectively located on both sides of the rope wheel 9, when the user pulls one of the main rope end 101 and the secondary rope end 102, the other one will start to reel in, and a connecting plate 12 is slidably installed on the main rope end 101, and the end of the connecting plate 12 is fixedly connected to the secondary rope end 102. Through the setting of the connecting plate 12, it is convenient for the user to pull the main rope end 101 and the secondary rope end 102.

[0035] See also Figure 4 and Figure 5 There are two groups of limit rods 3 symmetrically installed on the top of the splint 2. The two groups of limit rods 3 will further ensure the sliding stability of the splint 2, and at the same time ensure that the splint 2 will not rotate synchronously with the threaded tube 4. The length of the limit rods 3 is greater than the length of the threaded tube 4, ensuring that the splint 2 moves to a state of being in contact with the bottom top surface of the boom 1, and the top of the limit rods 3 is still located in the boom 1 to prevent the splint 2 from separating from the boom 1.

[0036] See also Figure 2 , Figure 4 and Figure 5 , the transmission assembly consists of a first bevel gear 6, a second bevel gear 7 and a gear transmission box 8;

[0037] Among them, a first bevel gear 6 fixedly connected to the top of the transmission block 5 is rotatably installed inside the top of the boom 1, and a gear transmission box 8 connected to a rope pulley 9 is fixedly installed on the top of the boom 1, and a second bevel gear 7 meshingly connected to the first bevel gear 6 is installed at the output end of the gear transmission box 8. Because the rope pulley 9 is connected to the input end of the gear transmission box 8, when the rope pulley 9 rotates, the gear transmission box 8 starts to operate, thereby prompting the second bevel gear 7 to start driving the first bevel gear 6 to rotate, ensuring that the transmission block 5 can smoothly obtain the power for rotation.

[0038] See also Figure 5 The transmission block 5 is designed as a rectangular block, and a sliding groove corresponding to the transmission block 5 is opened in the threaded barrel 4, so that the threaded barrel 4 can be smoothly slidably connected with the transmission block 5. At the same time, the shape of the transmission block 5 will ensure that the threaded barrel 4 can still drive the threaded barrel 4 to rotate when the transmission block 5 moves up and down.

[0039] See also Figure 2-Figure 5 A ball head 103 is fixedly installed at the end of the main rope end 101, so that the user can pull the main rope end 101 through the ball head 103. At the same time, because the diameter of the ball head 103 is larger than the diameter of the main rope end 101, the connecting plate 12 will not slide off the main rope end 101, ensuring that the main rope end 101 and the auxiliary rope end 102 can be connected for a long time;

[0040] Furthermore, a plurality of turns of pull rope 10 are provided on the rope wheel 9, and the number of turns of the pull rope 10 on the rope wheel 9 is at least four, so that when the main rope end 101 and the auxiliary rope end 102 are pulled, the rope wheel 9 will be driven to rotate, ensuring that the rope wheel 9 can rotate smoothly.

[0041] See also Figure 4 one Figure 6 Two sets of limiting plates 11 for limiting the pull rope 10 are symmetrically installed on the outer wall of the gear transmission box 8, and the inner walls of the limiting plates 11 are rotatably installed with limiting wheels 111 that are in contact with the outer wall of the pull rope 10. The pull rope 10 will be restricted by the limiting wheels 111 to prevent the main rope end 101 and the auxiliary rope end 102 from interfering with each other.

[0042] The working principle of the utility model is as follows: when it is necessary to transport the tower for large closure, first the lower part of the boom 1 is inserted into the tower, and the boom 1 is moved so that the top surface of the bottom of the boom 1 is in contact with the inner wall of the tower, and then the user pulls the auxiliary rope end 102 to cause the rope wheel 9 to start rotating. At this time, the rope wheel 9 starts to retract the main rope end 101 of the pull rope 10. At this time, the main rope end 101 will drive the dropped auxiliary rope end 102 to move upward through the connecting plate 12. When the rope wheel 9 starts to rotate, the gear transmission box 8 will drive the second bevel gear 7 to start rotating, so that the second bevel gear 7 drives the transmission block 5 to rotate through the first bevel gear 6, causing the threaded cylinder 4 to drive the clamping plate 2 to start descending until the bottom of the clamping plate 2 is in contact with the outer wall of the tower. At this time, the user cannot continue to pull the auxiliary rope end 102, and then the boom 1 can drive the tower to move. During the movement of the boom 1, the clamping plate 2 will reinforce the tower to improve safety.

[0043] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
