Description

Technical Field

[0001] This utility model relates to the field of wind power supporting equipment, specifically a bracket limiting component and a cable installation bracket. Background Technology

[0002] In the wind power industry, wind turbine generators operate in a complex and variable environment. The cable mounting brackets inside the tower are subjected to harsh conditions such as high-frequency vibration, strong wind impact, and temperature fluctuations for extended periods. Traditional cable mounting brackets are mostly composed of multiple brackets connected by welding. This connection method has limited strength, and under long-term vibration, stress concentration can easily occur at the connection points, leading to fatigue cracks, weld detachment, and other problems. This results in a decrease in the load-bearing capacity of the brackets and may even cause structural failure. At the same time, this connection method results in high installation costs and low installation efficiency. Therefore, it is necessary to develop a bracket limiting component and a cable mounting bracket to solve the problems of low connection strength, high installation costs, and low installation efficiency caused by the welding method used in existing cable mounting brackets. Utility Model Content

[0003] To address the aforementioned problems of low connection strength, high installation cost, and low installation efficiency caused by welding in existing cable mounting brackets, the technical solution adopted by this utility model is as follows:

[0004] A bracket limiting assembly includes a mounting column connected to a tower, a bracket connected to the mounting column, and a connector for connecting the mounting column and two adjacent brackets to achieve a fixed connection between the bracket and the mounting column.

[0005] Furthermore, the connector has a mounting groove for the bracket to be embedded on the side near the mounting post. The mounting groove has a limiting part that divides the mounting groove into at least two limiting grooves. The two limiting grooves are respectively connected to two adjacent brackets.

[0006] Furthermore, the side wall of the connector is provided with a first connection hole, and the end of the bracket connected to the connector is provided with a second connection hole. The fastener passes through the first connection hole and the second connection hole so that the bracket and the connector are fixedly connected.

[0007] Furthermore, the limiting part is provided with a positioning hole for the mounting post to be inserted.

[0008] Furthermore, the connector is provided with a third connecting hole, and the top of the mounting post is provided with a first mating part. The fastener passes through the third connecting hole and engages with the first mating part to fix the connector to the mounting post.

[0009] Furthermore, the first connecting hole penetrates through the two side walls of the limiting groove, the bracket is a channel steel, the second connecting hole penetrates through the bracket, and the fastener passes through the first connecting hole located on both sides of the limiting groove and the second connecting hole located on the bracket, so that the bracket is fixedly connected to the connector.

[0010] Furthermore, the cross-sectional shape of the mounting post is one of the following: circular, elliptical, or polygonal, and the cross-sectional shape of the mounting post matches the cross-sectional shape of the positioning hole.

[0011] Furthermore, each of the limiting grooves has at least two sets of first connecting holes, with the second connecting hole corresponding to the first connecting hole one-to-one.

[0012] A cable mounting bracket includes the bracket limiting component and a cable fixing component connected to the bracket.

[0013] Furthermore, the cable fixing assembly includes a cable clamp connector connected to the bracket, a lower cable clamp connected to the cable clamp connector, and an upper cable clamp connected to the lower cable clamp. The upper cable clamp and the lower cable clamp are provided with multiple clamping slots for fixing cables on opposite sides. The upper cable clamp and the lower cable clamp are locked by fasteners so that the cable is fixed in the clamping slots.

[0014] The beneficial effects of this utility model are as follows:

[0027] Please see Figures 1 to 8 The bracket limiting assembly shown includes a mounting column 1 connected to a tower, a bracket 2 connected to the mounting column 1, and a connector 3. The connector 3 is used to connect the mounting column 1 and two adjacent brackets 2 to achieve a fixed connection between the bracket 2 and the mounting column 1.

[0028] In this invention, the mounting column is directly connected to the tower, serving to support the entire cable mounting bracket and ensuring a certain distance between the cable and the tower surface to prevent damage from friction. The bracket is mainly used to fix the cable and other components used for cable fixing, ensuring effective fixation and avoiding structural failure due to long-term vibration. The connector is used to connect two adjacent brackets and mounting columns. By using the connector to firmly connect the mounting column and bracket, adjacent brackets are connected to each other while the bracket is fixed to the tower, effectively improving the ease of installation of the cable mounting bracket. This avoids problems such as weld point detachment and fatigue cracks that are prone to occur under high-frequency vibration in traditional welding methods, improving connection strength and stability. In addition, this design helps to disperse stress, reduce the burden on a single connection point, thereby reducing the possibility of fatigue cracks and enhancing the overall structural stability and reliability.

[0029] Furthermore, the connector 3 is provided with a mounting groove 31 for the bracket 2 to be embedded on the side near the mounting post 1. The mounting groove 31 is provided with a limiting part 32, which divides the mounting groove 31 into at least two limiting grooves 311. The two limiting grooves 311 are respectively connected to the two adjacent brackets 2.

[0030] In this invention, the connector has a mounting groove on the side near the mounting post for accommodating the bracket, providing a clear positioning space for the bracket. This allows the bracket to be quickly and accurately embedded into the connector, simplifying the installation process and effectively improving installation convenience. Furthermore, the mounting groove has a limiting part inside, which divides the mounting groove into two limiting grooves. The two limiting grooves are respectively for two adjacent brackets to be embedded in, allowing the two adjacent brackets to be precisely aligned and connected with the connector, effectively improving installation convenience and reliability. At the same time, it also ensures that the two adjacent brackets can be stably connected in their respective limiting grooves, avoiding fatigue cracks or structural failures caused by vibration or external forces. Therefore, through the design of the mounting groove and limiting groove, the bracket can be quickly embedded and accurately positioned, reducing the manual adjustment time during the installation process and improving installation efficiency. At the same time, the two limiting grooves can disperse the connection stress of the bracket, avoiding the problem of stress concentration at a certain point in traditional welding methods, and significantly improving the fatigue resistance of the overall structure.

[0031] Furthermore, in a preferred embodiment of this utility model, the limiting part is located in the middle of the mounting groove, so that the two limiting grooves formed are of the same length.

[0032] Furthermore, the side wall of the connector 3 is provided with a first connection hole 34, and the end of the bracket 2 connected to the connector 3 is provided with a second connection hole 21. The fastener passes through the first connection hole 34 and the second connection hole 21 so that the bracket 2 and the connector 3 are fixedly connected.

[0033] This invention provides a first connecting hole on the side wall of the connector and a second connecting hole at the end where the bracket connects to the connector. This allows fasteners to pass through both the first and second connecting holes simultaneously, tightly fixing the bracket and connector together. Compared to traditional welding connections, this mechanical connection method not only provides greater installation flexibility but also makes the structure more robust and reliable, easier to disassemble and maintain, and effectively prevents loosening or weld point detachment caused by vibration or external force, further improving connection stability and reliability.

[0034] Furthermore, the limiting part 32 is provided with a positioning hole 321 for the mounting post 1 to be inserted.

[0035] In this utility model, the limiting part is provided with a positioning hole, which is used to precisely embed the mounting column. This not only ensures that the mounting column can be accurately positioned in the predetermined position, but also increases the contact area and connection strength between the two through physical embedding. This allows the alignment work to be completed quickly and accurately during the installation process, reducing errors and improving installation efficiency. It also increases the mechanical locking effect between the two, avoiding relative movement caused by vibration or external force, thereby enhancing the stability of the overall structure.

[0036] Furthermore, the connector 3 is provided with a third connecting hole 33, and the top of the mounting post 1 is provided with a first mating part 11. The fastener passes through the third connecting hole 33 and engages with the first mating part 11 to fix the connector 3 to the mounting post 1.

[0037] This invention achieves a fixed connection between the connector and the mounting column by setting a third connecting hole and a first mating part, and using fasteners passing through the third connecting hole and connecting to the first mating part. This connection method can significantly improve the connection strength and stability between the connector and the mounting column. This connection structure is more flexible and robust than traditional welding, and can maintain stability in complex working environments. In addition, this connection structure can achieve high-precision alignment and positioning during installation, reduce errors, and ensure that each component can be installed accurately, thereby improving the reliability of the overall structure. Especially in the wind power industry, when facing harsh working conditions such as high-frequency vibration, strong wind impact, and temperature fluctuations, it can ensure the safety and stability of the cable mounting bracket.

[0038] Furthermore, the first connecting hole 34 penetrates the two side walls of the limiting groove 311, the bracket 2 is a channel steel, the second connecting hole 21 penetrates the bracket 2, and the fastener passes through the first connecting hole 34 located on both sides of the limiting groove 311 and the second connecting hole located on the bracket 2, so that the bracket 2 is fixedly connected to the connector 3.

[0039] In this utility model, the first connecting hole penetrates the two side walls of the limiting groove, and similarly, the second connecting hole penetrates the bracket. This means that the fastener can pass through both sides of the connector and both sides of the bracket at the same time, which realizes the fixed connection between the connector and the bracket, and can also effectively disperse stress and avoid local stress concentration, thereby improving the fatigue resistance of the overall structure. Furthermore, the bracket is made of channel steel, which has good load-bearing capacity and is easy to process, install and obtain.

[0040] Furthermore, the cross-sectional shape of the mounting post 1 is one of a circle, an ellipse, or a polygon, and the cross-sectional shape of the mounting post 1 matches the cross-sectional shape of the positioning hole 321.

[0041] In this invention, the cross-section of the mounting post is set to one of a circle, an ellipse, or a polygon. Correspondingly, the cross-sectional shape of the positioning hole matches the cross-sectional shape of the mounting post. This means that if the mounting post is circular, the positioning hole is also circular; if the mounting post is polygonal, the positioning hole is also a polygon of the same type. This shape-matching design of the mounting post and the positioning hole can further ensure that the mounting post can be accurately embedded into the positioning hole, thereby achieving high-precision positioning. At the same time, the precisely matched cross-sectional shape helps to disperse the force, avoid stress concentration at a certain point, reduce the risk of fatigue damage caused by long-term vibration, and improve the safety and service life of the entire structure. In addition, this also helps to simplify the installation process, thereby enhancing the stability and reliability of the overall structure.

[0042] Furthermore, each of the limiting grooves 311 has at least two sets of first connecting holes 34, and the second connecting hole 21 corresponds one-to-one with the first connecting hole 34.

[0043] In this invention, each limiting groove is provided with at least two sets of first connecting holes, and each set of first connecting holes includes two first connecting holes located on the two side walls of the limiting groove and whose axes coincide. This means that in each limiting groove, each side wall has at least two positions for fixed connection with fasteners. Correspondingly, the number and position of the second connecting holes on the bracket correspond one-to-one with the first connecting holes in the limiting groove, ensuring that each set of first connecting holes can find a corresponding second connecting hole so as to achieve a stable connection with fasteners. This design can effectively enhance the connection strength between the connector and the bracket, reduce the risk of overall structural instability due to the failure of a single connection point, and increase the number of connection points to help distribute the force more evenly, avoiding stress concentration on one or a few connection points, thereby improving the fatigue resistance of the entire system and extending its service life. In summary, by providing at least two sets of first connecting holes in each limiting groove and ensuring that the second connecting holes correspond one-to-one, this design greatly improves the connection strength and stability of the bracket limiting component, while taking into account installation accuracy and maintenance convenience, especially for fields with extremely high safety and reliability requirements such as the wind power industry.

[0044] The cable mounting bracket includes the bracket limiting component and the cable fixing component 4 connected to the bracket 2.

[0045] In this utility model, the cable mounting bracket includes a bracket limiting component and a cable fixing component. The cable fixing component is directly connected to the bracket and is used to fix and support the cable, ensuring that the cable can be effectively fixed inside the tower. By setting the bracket limiting component and the cable fixing component, the cable mounting bracket can ensure that the cable is firmly fixed in its position. At the same time, the entire cable mounting bracket can be effectively fixed inside the tower, which can not only effectively resist adverse factors such as high-frequency vibration, strong wind impact and temperature changes, but also effectively improve the connection stability and reliability between the cable mounting bracket and the tower. In terms of installation and maintenance, due to the modular design and mechanical connection instead of welding, the entire cable mounting bracket can be quickly installed and maintained. This not only reduces the initial installation cost, but also reduces the time and cost of subsequent maintenance.

[0046] Furthermore, the cable fixing assembly 4 includes a cable clamp connector 41 connected to the bracket 2, a lower cable clamp 42 connected to the cable clamp connector 41, and an upper cable clamp 43 connected to the lower cable clamp 42. The upper cable clamp 43 and the lower cable clamp 42 are provided with multiple clamping grooves 44 for fixing cables on opposite sides. The upper cable clamp 43 and the lower cable clamp 42 are locked by fasteners so that the cable is fixed in the clamping grooves 44.

[0047] In this invention, the cable connector is the part of the cable fixing assembly that is directly connected to the bracket. It acts as a bridge, firmly installing the cable fixing assembly onto the bracket system. The lower cable clamp is connected to the cable clamp connector, and the upper cable clamp is connected to the lower cable clamp. Each of them has multiple clamping slots on opposite sides for fixing cables. The clamping slots of the upper cable and the lower cable correspond one-to-one. The upper and lower cable clamps are locked together by fasteners to form a strong clamping force, which can effectively prevent the cable from loosening or shifting due to vibration, wind, or other external forces, thereby ensuring the safety and stability of the cable. The number and size of the clamping slots can be customized according to actual needs, which can adapt to the cable arrangement requirements of different specifications and quantities, enhancing the flexibility and adaptability of the cable installation bracket.

[0048] In summary, this cable fixing assembly, by introducing cable clamp connectors, upper cable clamps, lower cable clamps, and clamping grooves, provides an efficient, reliable, and flexible cable fixing structure, effectively improving the overall performance of the cable mounting bracket and providing a stable and reliable cable installation structure for the wind power industry.
