Abstract
Description
Technical Field
[0001] This utility model relates to the field of truss tower technology, and more specifically, to a modular connection device for truss towers. Background Technology
[0002] Truss-type towers are towers assembled from structural steel to support wind turbine generators. Because they are not limited by site or transportation constraints, they offer greater flexibility and are a good choice for cost reduction in the wind power industry. For example, patent application number CN202010185766.7 describes a truss-type wind turbine generator tower. It includes a central cross-shaped main tower column, surrounding secondary tower columns, crossbars connecting the main and secondary tower columns, web members connecting the secondary tower columns, and a lifting device for workers installed on the central main tower column. A key feature is the small span between the secondary tower columns, reducing the overall tower's footprint. Equidistant protective steel plates are installed on the main tower column, forming a semi-enclosed structure, saving materials, facilitating workers' access via ladders, and ensuring elevator safety. However, in this design, because the truss-type tower is assembled from structural steel, the connections between the structural steel components are not tight, resulting in poor stability and a tendency to loosen. Utility Model Content
[0003] The main objective of this invention is to provide a modular connection device for truss-type towers, which can effectively solve the problem in the prior art where, since truss-type towers are assembled from structural steel, the connection between the structural steels in the aforementioned devices is not tight, the stability between the structural steels is poor, and loosening is likely to occur.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a truss-type tower modular connection device, comprising a plurality of towers, which are connected by a tower frame. Each tower has an upper mounting plate installed on its upper circumferential surface and a lower mounting plate installed on its lower circumferential surface. The surfaces of the lower and upper mounting plates are provided with through mounting holes. A secondary positioning component is provided on the circumferential surface of the towers. A positioning post is fixedly installed on the lower surface of each tower and a positioning hole is provided on the upper surface of each tower. The positioning post is positioned inside the positioning hole by means of the secondary positioning component.
[0005] Preferably, all of the towers are inclined toward the center.
[0006] Preferably, a positioning ring is fixedly installed at the upper end of the tower.
[0007] Preferably, a positioning groove is formed on the lower end surface of the tower, and the positioning ring is disposed inside the positioning groove.
[0008] Preferably, the secondary positioning component includes a first mounting plate, a second mounting plate, and a locking hole. The first mounting plate and the second mounting plate are both disposed on the circumference of the tower, and the locking hole is opened on the circumference of the positioning column.
[0009] Preferably, the first mounting plate and the second mounting plate are each fixedly mounted with a locking post on their adjacent sides, and the top of the locking post is movably inserted through the tower rod and positioned inside the locking hole.
[0010] Preferably, a mounting sleeve is rotatably mounted on the side of the second mounting plate near the first mounting plate, and a mounting screw is engaged in the middle of the mounting sleeve, with the top end of the mounting screw rotatably disposed on the surface of the first mounting plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] (1) The positioning post is placed inside the positioning hole. At this time, the worker rotates the installation sleeve. Since the first and second mounting plates are both located on the circumference of the tower, and the locking hole is opened on the circumference of the positioning post, the locking posts are fixedly installed on the sides of the first and second mounting plates that are close to each other. The top of the locking post moves through the tower and is located inside the locking hole. The installation sleeve is rotatably installed on the side of the second mounting plate that is close to the first mounting plate. The installation screw is engaged in the middle of the installation sleeve. The top of the installation screw is rotatably set on the surface of the first mounting plate, which can drive the installation screw to the installation. The internal movement of the screw sleeve drives the two first and second mounting plates to move closer to each other, and simultaneously drives the two locking posts to move closer to each other, so that the locking posts are positioned inside the locking holes. This allows the positioning posts to be positioned inside the positioning holes, thus initially connecting the two towers. At this point, the upper and lower mounting plates of the two towers can be connected. Using bolts and other tools, the upper and lower mounting plates can be connected together for a secondary connection, ensuring the stability of the tower assembly connection. This double guarantee results in better tower stability. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0019] like Figure 1 , 2 As shown, a modular connection device for a truss-type tower includes several towers 1, which are connected by towers 2. Each tower 1 has an upper mounting plate 6 installed on its upper circumferential surface and a lower mounting plate 3 installed on its lower circumferential surface. The surfaces of the lower mounting plate 3 and the upper mounting plate 6 are provided with mounting holes 7. A secondary positioning component 5 is provided on the circumferential surface of each tower 1. A positioning post 4 is fixedly installed on the lower surface of each tower 1, and a positioning hole 9 is provided on the upper surface of each tower 1. The positioning post 4 is set inside the positioning hole 9 by the secondary positioning component 5.
[0020] like Figure 1 As shown, all the towers 1 mentioned above are inclined towards the center.
[0021] like Figure 2 , 3 As shown, a positioning ring 8 is fixedly installed on the upper end of the tower 1, and a positioning groove 10 is opened on the lower end surface of the tower 1. The positioning ring 8 is set inside the positioning groove 10. Setting the positioning ring 8 in the positioning groove 10 can make the connection between the two towers tighter when they are connected.
[0022] like Figure 2 , 3The secondary positioning component 5 shown in Figure 4 includes a first mounting plate 501, a second mounting plate 502, and a locking hole 506. The first mounting plate 501 and the second mounting plate 502 are both located on the circumference of the tower rod 1. The locking hole 506 is located on the circumference of the positioning post 4. A locking post 503 is fixedly installed on the side of the first mounting plate 501 and the second mounting plate 502 that is close to each other. The top end of the locking post 503 movably passes through the tower rod 1 and is located inside the locking hole 506. The second mounting plate 502 is close to the first mounting plate 501. A mounting sleeve 504 is rotatably mounted on one side of plate 501. A mounting screw 505 is engaged in the middle of the mounting sleeve 504. The top end of the mounting screw 505 is rotatably mounted on the surface of the first mounting clamp 501, positioning the positioning post 4 inside the positioning hole 9. At this time, the operator rotates the mounting sleeve 504. Since the first mounting clamp 501 and the second mounting clamp 502 are both located on the circumference of the tower rod 1, and the locking hole 506 is opened on the circumference of the positioning post 4, the first mounting clamp 501 and the second mounting clamp 502 are close to each other. Each mounting plate 501 is fixedly mounted with a locking post 503. The top of the locking post 503 moves through the tower rod 1 and is positioned inside the locking hole 506. A mounting sleeve 504 is rotatably mounted on the side of the second mounting plate 502 closest to the first mounting plate 501. A mounting screw 505 is engaged in the middle of the mounting sleeve 504. The top of the mounting screw 505 is rotatably positioned on the surface of the first mounting plate 501. This allows the mounting screw 505 to move into the mounting sleeve 504, thereby driving the two first mounting plates 501 and the second mounting plate 502 to move towards each other. The two tower rods 1 are initially connected by moving the two adjacent sides together, which simultaneously drives the two locking posts 503 to move towards each other, so that the locking posts 503 are set inside the locking holes 506. This allows the positioning posts 4 to be set inside the positioning holes 9, thus initially connecting the two tower rods 1. At this time, the upper mounting plates 6 and lower mounting plates 3 of the two tower rods 1 can be connected. By using bolts and other tools, the upper mounting plates 6 and lower mounting plates 3 can be connected together for a secondary connection, ensuring the stability of the tower assembly connection. This double guarantee results in better tower stability.
[0023] The working principle of this truss-type tower modular connection device:
[0024] In use, when assembling the tower components, the positioning post 4 is first placed inside the positioning hole 9. At this time, the operator rotates the installation sleeve 504. Since the first mounting plate 501 and the second mounting plate 502 are both located on the circumference of the tower rod 1, and the locking hole 506 is located on the circumference of the positioning post 4, locking posts 503 are fixedly installed on the sides of the first mounting plate 501 and the second mounting plate 502 that are close to each other. The top of the locking post 503 moves through the tower rod 1 and is located inside the locking hole 506. The installation sleeve 504 is rotatably installed on the side of the second mounting plate 502 that is close to the first mounting plate 501. An installation screw 505 is engaged in the middle of the installation sleeve 504. The top of the installation screw 505 is rotatably positioned on the first... By mounting the clamping plate 501, the mounting screw 505 can be driven to move into the mounting sleeve 504, which in turn drives the two first mounting clamping plates 501 and the second mounting clamping plate 502 to move closer to each other. At the same time, the two locking pins 503 are driven to move closer to each other, so that the locking pins 503 are set inside the locking holes 506, and the positioning pins 4 are set inside the positioning holes 9, thus initially connecting the two tower rods 1. At this time, the upper mounting plate 6 and the lower mounting plate 3 of the two tower rods 1 can be connected. With bolts and other tools, the upper mounting plate 6 and the lower mounting plate 3 can be connected together for a secondary connection to ensure the stability of the tower assembly connection. This double guarantee results in better tower stability.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
