Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, specifically to a cable positioning component for power construction. Background Technology

[0002] During power construction, cable positioning and fixing is an important task. If the cable is not securely positioned, it is prone to displacement, entanglement and other problems during construction or later use, which can affect the normal operation of the power system and may even cause safety accidents.

[0003] Existing cable positioning devices are usually simple in structure, and most can only position a single cable, which is not very versatile. They are also not flexible enough in adjusting the clamping force, making it difficult to meet the cable positioning requirements of different construction scenarios. Utility Model Content

[0004] This utility model aims to solve the above-mentioned technical problems by providing a cable positioning component for power construction.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A cable positioning component for power construction includes a U-shaped frame, wherein multiple sets of limiting blocks are installed inside the U-shaped frame, and clamping blocks are installed on each of the multiple sets of limiting blocks.

[0007] The limiting block and clamping block, and the clamping groove between the two clamping blocks are all provided for use with cable conductors, and the connecting block is installed on the U-shaped frame;

[0008] The connecting block is equipped with an adjustment device that limits the position of the clamping block.

[0009] Preferably, the inner walls of the plurality of clamping slots are each equipped with a protective rubber layer. The rubber layer can act as a buffer when clamping the cable, preventing the clamping slot from causing wear on the cable surface, while increasing the friction between the cable and the clamping slot, thus improving the stability of the clamping.

[0010] Preferably, the multiple clamping slots are staggered vertically. This staggered arrangement allows multiple cables to be positioned separately, avoiding mutual compression and entanglement between the cables, which is beneficial for heat dissipation and subsequent maintenance.

[0011] Preferably, the inner sides of the two upper ends of the U-shaped frame are chamfered, and the lower end of the connecting block is equipped with a guide block for use with the chamfer. The connecting block, the guide block and the U-shaped frame are all provided with threaded holes, and fixing bolts are installed in the threaded holes. The cooperation between the guide block and the chamfer of the U-shaped frame facilitates the installation and positioning of the connecting block and the U-shaped frame. The fixing bolts then fix the three together, improving the strength of the connection.

[0012] Preferably, positioning posts are installed on both ends of the U-shaped frame, and a positioning groove is provided at the lower end of the connecting block to cooperate with the positioning posts. The cooperation between the positioning posts and the positioning groove further improves the positioning accuracy when the connecting block is installed with the U-shaped frame, ensuring the accuracy of the installation position of the connecting block.

[0013] Preferably, a guide post is installed at the lower end of the connecting block, and guide holes are provided on both the limiting block and the clamping block to cooperate with the guide post. The cooperation between the guide post and the guide hole can guide the movement of the limiting block and the clamping block, ensuring that they move in a fixed direction during the adjustment process and avoiding deviation.

[0014] Preferably, the adjusting device includes an adjusting bolt for the threaded connection block and a stop plate that can move outside the guide post. By rotating the adjusting bolt, the stop plate moves up and down, pushing the clamping block to move, thereby adjusting the distance between the clamping block and the limiting block, and between the clamping blocks themselves, thus adjusting the clamping force of the clamping groove to adapt to the positioning requirements of cables of different specifications.

[0015] Preferably, the U-shaped frame is provided with mounting holes for fixing, through which the entire positioning component can be fixedly installed at the required construction location, such as a wall or bracket, to ensure the overall stability of the positioning component.

[0016] With the above structure, this utility model has the following advantages:

[0017] 1. This utility model forms multiple clamping slots by setting multiple sets of limiting blocks and clamping blocks, which can simultaneously position multiple cables. The clamping slots are staggered vertically to avoid mutual interference between cables.

[0018] 2. The adjustment device allows the clamping force of the clamping groove to be flexibly adjusted according to the cable specifications, improving the versatility of the positioning component.

[0019] 3. The rubber layer inside the clamping groove protects the cable surface and increases friction, thus improving clamping stability.

[0020] 4. The connecting block and the U-shaped frame are fixed together by a variety of positioning structures, which makes installation convenient and the connection firm. The overall structure is simple and highly practical.

[0021] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0028] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] The present invention will now be described in further detail in conjunction with the full text.

[0031] Combined with appendix Figures 1-4A cable positioning component for power construction includes a U-shaped frame 1. Multiple sets of limiting blocks 2 are installed inside the U-shaped frame 1, and clamping blocks 3 are installed on each of the multiple sets of limiting blocks 2. Grooves 4 for use with cable conductors are opened between the limiting blocks 2 and the clamping blocks 3, and between two clamping blocks 3. Connecting blocks 5 are installed on the U-shaped frame 1. Adjustment devices 6 that limit the position of clamping blocks 3 are installed on the connecting blocks 5.

[0032] In the specific implementation of this utility model, the inner walls of multiple clamping grooves 4 are all equipped with protective rubber layers. The center-line spacing between adjacent clamping grooves 4 is ≥ 1.2 times the cable diameter, and the lateral misalignment distance is ≥ 20mm, which can reduce electromagnetic interference between cables (tests show that it can reduce the mutual inductance coefficient by 15%-20%), and reserve independent heat dissipation space for each cable, thereby reducing the operating temperature by 5-8℃.

[0033] The rubber layer provides a dual benefit: firstly, it cushions the cable surface during clamping, preventing the hard clamping groove from abrading the insulation layer; secondly, it increases the friction between the cable and the inner wall of the clamping groove, improving clamping stability and preventing cable slippage. The rubber layer uses aging-resistant rubber with a Shore hardness of 60-70, ensuring 30%-50% deformation capacity to fit cables of different diameters, while also providing elastic cushioning to offset the impact of construction vibrations. Tests have shown it can reduce cable insulation wear by over 90%. Simultaneously, the anti-slip texture on the rubber surface increases the coefficient of friction to 0.8 (compared to 0.3 for metal surfaces), effectively preventing axial cable slippage.

[0034] In a specific implementation of this utility model, multiple clamping grooves 4 are staggered vertically.

[0035] The staggered layout ensures that multiple cables do not touch each other during positioning, effectively avoiding squeezing and tangling between cables. This not only facilitates cable heat dissipation but also makes it easier to quickly identify individual cables during later maintenance.

[0036] In this invention, the inner sides of the two upper ends of the U-shaped frame 1 are chamfered. A guide block 7, used in conjunction with the chamfer, is installed at the lower end of the connecting block 5. Threaded holes are provided on the connecting block 5, guide block 7, and U-shaped frame 1, and fixing bolts 13 are installed in these threaded holes. The chamfer and the tapered surface of the guide block (taper 1:10) allow for rapid pre-positioning of the connecting block, with a positioning error ≤0.5mm. Combined with M8 fixing bolts (tensile strength ≥800MPa), the connection strength reaches over 30kN, meeting the requirements of outdoor strong wind and vibration environments.

[0037] The chamfer and guide block work together to guide the installation of the connecting block and the U-shaped frame, ensuring that the two are quickly aligned; the fixing bolts fasten the three together through the threaded holes, improving the stability of the overall structure.

[0038] In a specific implementation of this utility model, positioning posts 8 are installed on both ends of the U-shaped frame 1, and positioning grooves 9 are provided at the lower end of the connecting block 5 to cooperate with the positioning posts 8.

[0039] The engagement of the positioning post 8 and the positioning groove 9 further improves the installation accuracy of the connecting block, avoiding misalignment of the clamping groove due to installation deviations and ensuring the consistency of cable positioning. The positioning post 8 and the positioning groove 9 adopt a clearance fit (gap 0.05-0.1mm) to further constrain the lateral displacement of the connecting block, ensure the positioning accuracy of the clamping groove, and avoid uneven clamping force due to installation deviations.

[0040] In a specific implementation of this utility model, a guide post 12 is installed at the lower end of the connecting block 5, and guide holes 10 are provided on both the limiting block 2 and the clamping block 3 to cooperate with the guide post 12.

[0041] The sliding fit between the guide post 12 and the guide hole 10 provides directional constraint for the movement of the clamping block, ensuring that the clamping block moves in a straight line during the adjustment process and avoiding instability in the clamping groove size caused by offset.

[0042] In a specific implementation of this invention, the adjusting device 6 includes an adjusting bolt 601 for connecting the threaded block 5 and a stop plate 602 that can move outside the guide post 12. A through hole is provided on the stop plate 602 to cooperate with the guide post 12.

[0043] By rotating the adjusting bolt 601, the abutment plate 602 can be pushed up and down along the guide post 12. The abutment plate 602 then presses against the clamping block, thereby adjusting the spacing of the clamping grooves 4. Furthermore, the multiple sets of clamping grooves 4 are of different sizes to accommodate cables of different diameters, improving the versatility of the positioning component.

[0044] In a specific implementation of this utility model, the U-shaped frame 1 is provided with mounting holes 11 for fixing.

[0045] The mounting holes can be used with expansion bolts and other connectors to fix the positioning component to the wall, bracket, or other basic structure, ensuring that the positioning component does not shift during construction or use.

[0046] The working principle of this utility model:

[0047] 1. Fix the U-shaped frame 1 to the construction position through the mounting holes 11;

[0048] 2. Place the cable into the corresponding clamping groove 4, rotate the adjusting bolt 601, push the abutment plate 602 down, so that the clamping block 3 slides along the guide post 12 until the clamping groove 4 tightly clamps the cable;

[0049] 3. The rubber layer adheres to the cable surface to provide protection and prevent slipping; the staggered grooves 4 ensure that the cables do not interfere with each other.

[0050] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
