Description

Technical Field

[0001] The invention relates to the technical field of alloy copper rods, in particular to an alloy copper rod for a transmission structure of a feeder. Background Art

[0002] In the feeder transmission system, alloy copper rods, as core components of power transmission, are subject to high torque, high-frequency reciprocating motion, and extreme temperature environments for a long time. Traditional alloy copper rods can no longer meet the requirements of long-term use in actual applications. Traditional solid copper rods are prone to plastic deformation under continuous impact loads. When the core temperature of the rod exceeds the recrystallization temperature of the copper alloy, the material's yield strength drops by more than 40%, resulting in a significant increase in the risk of transmission failure. At the same time, the heat dissipation structure of existing alloy copper rods is difficult to penetrate into the heat source area inside the rod body. When the temperature difference between the center and surface temperatures of the rod body is too large, microcracks may be caused and fatigue fracture of the copper rod may be accelerated. In addition, the high-frequency vibrations during the transmission process are directly transmitted through the rigid rod body, inducing structural resonance and generating harsh noise. Existing alloy copper rods cannot balance heat dissipation and noise reduction performance. To address the above problems, we propose an alloy copper rod for the feeder transmission structure. Summary of the Invention

[0003] In order to overcome the technical defects of the prior art, the present invention provides an alloy copper rod for a feeder transmission structure, which has the advantages of sufficient heat dissipation and obvious noise reduction.

[0004] The technical solution adopted by the present invention is: it includes an outer copper sleeve, an inner copper rod and a heat-conducting support part, the inner wall of the outer copper sleeve is provided with a docking groove, the outer wall of the inner copper rod is provided with a docking ridge that can be snapped into the docking groove, the inner copper rod and the outer copper sleeve are also fixedly connected by a connecting piece, the heat-conducting support part is arranged in the first groove provided on the outer wall of the inner copper rod, and the heat-conducting support parts are fixed by a connecting piece, the inner copper rod is provided with a water hole running through each first groove, the end face center position of the inner copper rod and the outer periphery near the two end faces are respectively provided with a first water injection hole and a second water injection hole, the two water injection holes are in a connected state, and the inner copper rod is also provided with a device for connecting the first water injection hole, the second water injection hole and the water-through hole. The connecting cavity allows cooling water to be injected into the first groove through the first or second water injection hole to immerse the heat-conducting support part. The overall structure adopts an assembled structure design. The inner copper rod and the outer copper sleeve adopt the embedded meshing of the butt groove and the convex strip, and the circumferential locking mechanism of the waist-shaped connecting plate bolt forms a dual torsional load-bearing system, which effectively resists high-load alternating stress and significantly reduces the risk of plastic deformation. The heat-conducting support part is located between the inner copper rod and the outer copper sleeve. During actual use, cooling water can be injected through either the first or second water injection hole. The first and second water injection holes are located on the end face and outer periphery of the inner copper rod respectively, which can meet the water injection cooling requirements in different application scenarios and effectively improve the heat conduction efficiency. The coordinated design of the first groove and the heat-conducting support part not only increases the heat dissipation area, but also ensures that the cooling water can be evenly distributed around the heat-conducting support part, further improving the heat dissipation effect. During the transmission process, the circulation of cooling water effectively reduces the rod temperature and reduces the micro cracks caused by excessive temperature differences, thereby extending the service life of the alloy copper rod.

[0005] Preferably, the heat-conducting support portion is composed of an arc-shaped piece and a plurality of U-shaped support pieces arranged on the outer surface of the arc-shaped piece. The arc-shaped piece fits in the first groove, and the U-shaped support piece is provided with a water-permeable groove so that the cooling water can penetrate into the interior of the U-shaped support piece. The design of the water-permeable groove not only promotes the uniform distribution of the cooling water, but also increases the contact area between the heat-conducting support portion and the cooling water, thereby enhancing the heat exchange efficiency between the heat-conducting support portion and the cooling water.

[0006] Preferably, sound-absorbing cotton is provided on the inner wall of the U-shaped support plate. The setting of the sound-absorbing cotton effectively reduces the noise generated by friction and vibration during the transmission process. At the same time, the sound-absorbing cotton also has certain heat insulation properties, which can block the transfer of heat to a certain extent, and further assist the cooling water in the heat dissipation of the alloy copper rod, thereby ensuring the efficient and stable operation of the transmission structure.

[0007] Preferably, the inner wall of the first groove is provided with a magnet layer, and the fitting surface between the arc-shaped sheet and the first groove is provided with a magnetic coating that can be adsorbed by the magnet layer. The magnet layer and the magnetic coating are provided for temporarily fixing the arc-shaped sheet, so that the arc-shaped sheet can be quickly and accurately positioned in the first groove during the installation process, without the need for additional fixing devices or complicated installation steps, thereby greatly improving the installation efficiency.

[0008] Preferably, the connecting piece is composed of a fixing seat, a plurality of connecting rods integrally formed with the fixing seat at one end, and a connecting seat detachably connected to the connecting rods. The end of the connecting rod is provided with a thread, and the connecting seat is connected to the connecting rod by the cooperation of a second bolt and a thread, so that the connecting piece has good detachability and flexibility, and is easy to maintain and replace.

[0009] Preferably, both end surfaces of the inner copper rod are provided with second grooves for installing the fixing seat and the connecting seat, and a first through groove for the connecting rod to pass through is opened between the two second grooves. The setting of the second grooves enables the fixing seat and the connecting seat to be stably installed at both ends of the alloy copper rod, thereby enhancing the stability of the structure, and the design of the first through groove allows the connecting rod to pass through smoothly, ensuring an effective connection between the connector and the alloy copper rod, and also providing convenience for the assembly of the transmission structure.

[0010] Preferably, a second through slot for the connecting rod to pass through is provided in the arc-shaped piece of the heat-conducting support portion. The design of the second through slot enables the connecting rod to pass through the arc-shaped piece of the heat-conducting support portion smoothly, thereby ensuring the structural stability of the arc-shaped piece.

[0011] Preferably, external screw holes are provided on both end surfaces of the outer copper sleeve, and internal screw holes are provided on both end surfaces of the inner copper rod. Both end surfaces of the inner copper rod and the outer copper sleeve are connected by fitting together through connecting parts, external screw holes and internal screw holes, which simplifies the assembly process and improves assembly efficiency.

[0012] Preferably, the connecting piece is composed of a waist-shaped connecting piece and a first bolt. Two through-holes are provided on the waist-shaped connecting piece, which are used to align with the outer screw hole and the inner screw hole respectively. The first bolt passes through the through-hole and is installed into the outer screw hole or the inner screw hole to realize the assembly and fixation of the outer copper sleeve and the inner copper rod. The first bolt serves as a fastening element. By passing through the through-hole and cooperating with the thread of the outer screw hole or the inner screw hole, the outer copper sleeve and the inner copper rod are firmly fixed. The connection method is simple and easy, and can provide sufficient strength and stability.

[0013] Preferably, the connecting member also includes a common ring, and the common ring and each of the waist-shaped connecting pieces are made by an one-piece molding process. The one-piece molding technology ensures the overall strength of the common ring and the waist-shaped connecting piece, thereby enhancing the overall structural strength of the connecting member, making it less likely to break or loosen, providing a strong guarantee for the long-term stable operation of the transmission structure, and making the connecting member more stable and reliable during the assembly process.

[0014] The beneficial effects of the present invention are: 1. The inner copper rod and outer copper sleeve of the present invention adopt the embedded engagement of the butt groove and the convex strip, and cooperate with the circumferential locking mechanism of the waist-shaped connecting plate bolt to form a dual torsional load-bearing system, effectively resisting high-load alternating stress and significantly reducing the risk of plastic deformation. The water hole running through the inner copper rod and the dual water injection holes (a first water injection hole in the center and a second water injection hole in the periphery) construct a three-dimensional cooling circuit, allowing the cooling water to fully immerse the heat-conducting support part through the connecting cavity, directly conducting away the internal heat source, and avoiding the problem of material softening caused by local high temperature.

[0015] 2. The arc-shaped piece of the thermal support part is embedded with a magnetic coating, which can be quickly pre-positioned into the first groove for adsorption, facilitating rapid assembly of the connector. The water-permeable grooves on the surface of the U-shaped support piece promote the penetration of coolant, and the sound-absorbing cotton on the inner wall absorbs high-frequency vibrations, thereby simultaneously solving the problems of uneven heat dissipation and noise conduction.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings: like Figures 1-9 As shown, this embodiment provides an alloy copper rod for a feeder transmission structure, comprising an outer copper sleeve 1, an inner copper rod 2 and a heat-conducting support part 4. The inner wall of the outer copper sleeve 1 is provided with a docking groove 11, and the outer wall of the inner copper rod 2 is provided with a docking ridge 23 that can be snapped into the docking groove 11. The inner copper rod 2 and the outer copper sleeve 1 are also fixedly connected by a connecting piece 3, the heat-conducting support part 4 is arranged in the first groove 21 opened on the outer wall of the inner copper rod 2, and each heat-conducting support part 4 is fixed by a connecting piece 5. A water through hole 27 is provided in the inner copper rod 2 that passes through each first groove 21, and a first water injection hole 25 and a second water injection hole 26 are respectively provided at the center position of the end face of the inner copper rod 2 and near the outer periphery of the two end faces. The two water injection holes are in a connected state. A connecting cavity 28 is also provided in the inner copper rod 2 for connecting the first water injection hole 25, the second water injection hole 26 and the water through hole 27, so that cooling water can be injected into the first groove 21 through the first water injection hole 25 or the second water injection hole 26 to immerse the heat-conducting support part 4.

[0019] The present invention adopts an assembled structural design as a whole. The inner copper rod 2 and the outer copper sleeve 1 adopt the embedded meshing of the docking groove 11 and the convex strip, and cooperate with the circumferential locking mechanism of the waist-shaped connecting piece 31 bolt to form a dual torsional bearing system, which effectively resists high-load alternating stress and greatly reduces the risk of plastic deformation. The heat-conducting support part 4 is located between the inner copper rod 2 and the outer copper sleeve 1. During actual use, cooling water can be injected through any one of the first water injection hole 25 and the second water injection hole 26. The first water injection hole 25 and the second water injection hole 26 are respectively located on the end face and the outer periphery of the inner copper rod 2, which can meet the water injection cooling in different application scenarios and effectively improve the heat conduction efficiency. The matching design of the first groove 21 and the heat-conducting support part 4 not only increases the heat dissipation area, but also ensures that the cooling water can be evenly distributed around the heat-conducting support part 4, further improving the heat dissipation effect. During the transmission process, the circulation of the cooling water effectively reduces the rod temperature and reduces the micro cracks caused by excessive temperature difference, thereby extending the service life of the alloy copper rod.

[0020] Specific as Figure 8 As shown, the heat-conducting support part 4 is composed of an arc-shaped piece 41 and a plurality of U-shaped support pieces 42 arranged on the outer surface of the arc-shaped piece 41. The arc-shaped piece 41 is fitted in the first groove 21. The U-shaped support piece 42 is provided with a water-permeable groove 43, so that the cooling water can be immersed in the U-shaped support piece 42. The design of the water-permeable groove 43 not only promotes the uniform distribution of the cooling water, but also increases the contact area between the heat-conducting support part 4 and the cooling water, thereby enhancing the heat exchange efficiency between the heat-conducting support part 4 and the cooling water. In addition, the U-shaped structure of the U-shaped support piece 42 increases the overall strength of the heat-conducting support part 4, making it more stable and reliable when facing high-load transmission. This design not only optimizes the heat conduction path, but also improves the durability of the alloy copper rod through structural reinforcement, ensuring the long-term stable operation of the transmission structure.

[0021] Sound-absorbing cotton 44 is provided on the inner wall of the U-shaped support plate 42. The setting of the sound-absorbing cotton 44 effectively reduces the noise generated by friction and vibration during the transmission process. At the same time, the sound-absorbing cotton 44 also has certain heat insulation performance, which can block the transfer of heat to a certain extent, further assisting the cooling water in the heat dissipation of the alloy copper rod, and ensuring the efficient and stable operation of the transmission structure.

[0022] The inner wall of the first groove 21 is provided with a magnet layer, and the fitting surface between the arc-shaped piece 41 and the first groove 21 is provided with a magnetic coating that can be adsorbed by the magnet layer. The setting of the magnet layer and the magnetic coating for temporarily fixing the arc-shaped piece 41 enables the arc-shaped piece 41 to be quickly and accurately positioned in the first groove 21 during the installation process, without the need for additional fixing devices or complicated installation steps, thereby greatly improving the installation efficiency.

[0023] Specific as Figure 7 As shown, the connecting member 5 is composed of a fixing seat 51, a plurality of connecting rods 52 integrally formed with the fixing seat 51 at one end, and a connecting seat 53 detachably connected to the connecting rod 52. The end of the connecting rod 52 is provided with a thread, and the connecting seat 53 is connected to the connecting rod 52 by the cooperation of a second bolt 54 and the thread, so that the connecting member 5 has good detachability and flexibility, and is easy to maintain and replace.

[0024] Specific as Figure 4 and Figure 8As shown, both end surfaces of the inner copper rod 2 are provided with second grooves 22 for installing the fixing seat 51 and the connecting seat 53, and a first through groove 29 for the serial rod 52 to pass through is provided between the two second grooves 22. The setting of the second groove 22 enables the fixing seat 51 and the connecting seat 53 to be stably installed at both ends of the alloy copper rod, thereby enhancing the stability of the structure. The design of the first through groove 29 allows the serial rod 52 to pass through smoothly, ensuring the effective connection between the connector 5 and the alloy copper rod, and also providing convenience for the assembly of the transmission structure. The arc-shaped piece 41 of the heat-conducting support part 4 is provided with a second through groove 4 for the serial rod 52 to pass through. 5. The design of the second through groove 45 enables the connecting rod 52 to smoothly pass through the arc-shaped piece 41 of the heat-conducting support part 4, thereby ensuring the structural stability of the arc-shaped piece 41. External screw holes 12 are provided at both end surfaces of the outer copper sleeve 1, and internal screw holes 24 are provided at both end surfaces of the inner copper rod 2. Both end surfaces of the inner copper rod 2 and the outer copper sleeve 1 are connected by the matching assembly of the connecting piece 3, the external screw holes 12 and the internal screw holes 24, which not only simplifies the assembly process and improves the assembly efficiency, but also enhances the stability and reliability of the connection through the threaded connection. The tight fit between the outer copper sleeve 1 and the inner copper rod 2 effectively prevents loosening and falling off, thereby ensuring the stability and durability of the transmission structure.

[0025] Specific as Figure 9 As shown, the connecting piece 3 is composed of a waist-shaped connecting piece 31 and a first bolt 33. The waist-shaped connecting piece 31 is provided with two through-holes for aligning the outer screw hole 12 and the inner screw hole 24 respectively. The first bolt 33 is inserted into the outer screw hole 12 or the inner screw hole 24 after passing through the through-hole to realize the assembly and fixation of the outer copper sleeve 1 and the inner copper rod 2. The first bolt 33 is used as a fastening element. By passing through the through-hole and cooperating with the thread of the outer screw hole 12 or the inner screw hole 24, the outer copper sleeve 1 and the inner copper rod 2 are firmly fixed. The connection method is simple and easy, and can provide sufficient strength and stability. The connecting piece 3 also includes a common ring 32. The ring 32 and each waist-shaped connecting piece 31 are made by an integrated molding process. The integrated molding technology ensures the overall strength of the common ring 32 and the waist-shaped connecting piece 31, thereby enhancing the overall structural strength of the connector 3, making it less likely to break or loosen, providing a strong guarantee for the long-term stable operation of the transmission structure, and making the connector 3 more stable and reliable during the assembly process. The setting of the common ring 32 forms a unified whole between the multiple waist-shaped connecting pieces 31, effectively avoiding the relative displacement between the connecting pieces, thereby further improving the stability and durability of the transmission structure.
