Description

Technical Field

[0001] The present invention belongs to the technical field of cable trays, and particularly relates to a cable tray for intelligent power grid wire laying. Background Art

[0002] As a key supporting structure for cable laying in the power system, cable trays are widely used in fields such as buildings, industrial facilities, and intelligent power grids. Traditional suspended cable trays mainly include types such as trough type, tray type, and ladder type. Their basic structure usually consists of metal brackets, cantilever arms, and supporting installation accessories, and the surface mostly adopts galvanizing or spraying processes to improve corrosion resistance. However, with the rapid development of intelligent power grids, the power load density has increased significantly, the cable layout has become more complex, and the operating environment is often accompanied by challenges of high-frequency vibration and temperature rise. Traditional cable trays have shown significant defects in the following aspects.

[0003] Insufficient heat dissipation performance: Existing cable trays mostly rely on natural convection or simple ventilation holes for heat dissipation. The heat dissipation efficiency is restricted by environmental conditions, which easily leads to accelerated aging of the cable insulation layer and even the risk of short circuit; Poor adaptability of the clamping mechanism: Traditional clamping structures mostly adopt fixed straps or bolt locking designs, and cannot dynamically adjust the clamping force according to the diameter difference of cables (such as 10 - 50 mm). In actual applications, over-tight clamping is likely to cause damage to the cable epidermis, while over-loose clamping leads to cable displacement or detachment, especially in a vibrating environment, the failure rate increases significantly; Low efficiency of the shock absorption system: Traditional cable trays often use a single spring shock absorber, and its natural frequency is prone to resonance with the operating vibration frequency of power grid equipment, resulting in increased friction between the cable and the cable tray; Therefore, it is necessary to design a cable tray for intelligent power grid wire laying to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a cable tray for intelligent power grid wire laying to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A cable tray for intelligent power grid wire laying, comprising: A cable tray main body, which includes a main hoisting frame and a support crossbeam fixed inside the main hoisting frame; A heat dissipation mechanism, arranged on one side of the cable tray main body, including a heat insulation plate, heat dissipation pipes, heat dissipation fins, and a heat dissipation silica gel pad, and the heat dissipation silica gel pad is filled with heat-conducting silicone oil; A suspension mechanism, arranged on the upper side of the cable tray main body, including a suspension rod, a buffer seat, a connection seat, and a buffer and shock absorption mechanism; A clamping mechanism, arranged inside the support crossbeam, including a clamping seat, a clamping pressure column, a clamping arm, and a clamping claw; The support base is installed on the outer side of the support crossbeam through the installation bracket. The main frame cover plate is arranged on the upper side of the hoisting main frame, and ventilation holes are provided on the surface.

[0006] Preferably, the heat dissipation mechanism further includes a circulation pump, which is communicated with the heat dissipation silica gel pad through a connecting pipe and a connector, and a connecting head is installed at one end of the heat dissipation pipe. The upper surface of the heat dissipation silica gel pad is arc-shaped, and the heat dissipation pipes are communicated with each other.

[0007] Preferably, the suspension mechanism further includes a suspension cable, which passes through the connecting seat and the buffer rod and is wound in the winding groove on the surface of the connecting seat. The buffer and shock absorption mechanism includes a buffer spring, a damping sliding seat and a damping sliding groove. A fixing plate is fixedly installed on one side of the damping sliding seat, and an installation clamping block is arranged on one side of the fixing plate.

[0008] Preferably, in the clamping mechanism, when the clamping pressure column presses down, it drives the clamping arm and the clamping claw to rotate. The shapes of the clamping arm and the clamping claw are both V-shaped, and a limiting plate is arranged at the upper end of the clamping arm.

[0009] Preferably, a support pressing frame is arranged on one side of the installation bracket and is fixed by a support screw rod and a support screw sleeve. The ventilation holes of the main frame cover plate are equally distributed, and positioning protrusions are arranged on the lower side.

[0010] Preferably, the buffer and shock absorption mechanism further includes a damping seat, a damping sliding column and a damping spring. A guiding push plate is arranged inside the buffer seat, and the guiding push plate is slidably sleeved outside the positioning plate. A buffer guiding column is installed inside the buffer seat.

[0011] Preferably, the heat dissipation pipe is communicated with the heat dissipation silica gel pad, and heat dissipation fins are installed on the surface of the heat dissipation pipe. A support plate is installed on the support base for supporting the heat dissipation silica gel pad.

[0012] Preferably, a through hole is arranged in the middle of the connecting seat, and the through hole is communicated with the installation groove. The suspension cable is clamped in the guiding groove on the surface of the buffer rod, and one end is tied to the installation groove.

[0013] Preferably, a damping ball is arranged at one end of the damping sliding column and contacts the damping push plate on the guiding push plate. The other end of the damping sliding column presses on the damping spring.

[0014] Preferably, the clamping mechanism further includes a return spring and a rotating column. A rotating guiding groove is formed on the clamping arm and is rotatably connected with the rotating column at the lower end of the clamping pressure column.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Integrated design of adaptive clamping and anti-vibration: The V-shaped clamping arm and involute guide groove structure support dynamic adjustment of the cable diameter, the clamping force range is adjustable, and the overload protection threshold is automatically triggered (the reset spring releases the buffer when the pressure exceeds the limit), reducing the cable skin damage rate compared with traditional fixed clamping; the non-linear rotating guide groove of the clamping mechanism converts longitudinal vibration into rotational motion, combined with the friction damping of the suspension cable, and for every 10% increase in the vibration amplitude, the clamping force adaptively increases by 8% - 12%, and the cable displacement is ≤1mm in a high-frequency vibration environment.

[0016] 2. Efficient active heat dissipation and temperature adaptive control: Through the direct-contact heat dissipation silicone pad, the heat-conducting silicone oil circulation system and the heat sink forced convection, a three-level heat dissipation network of "contact - conduction - convection" is formed, and the temperature in the high-density cable area can be stably controlled within the safe temperature. The arc design of the heat dissipation silicone pad and the V-shaped clamping claw cooperate with each other. When the cable expands due to heat, the softening rate of the silicone pad matches the clamping angle, realizing dynamic balance of the clamping force and avoiding cable damage caused by thermal stress.

[0017] 3. Multi-stage composite shock absorption and high-reliability hoisting: The suspension cable winding friction damping and the buffer shock absorption mechanism (including hydraulic damping sliding columns, spring groups) form a parallel shock absorption, reducing the vibration transmission rate and effectively suppressing the resonance risk; the contact surface between the guiding push plate and the damping ball adopts a wear-resistant coating, combined with redundant buffer guide columns (double-backup structure), and the system can still maintain more than 80% of the shock absorption efficiency under extreme loads, extending the service life cycle.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1 to 10 , the present invention provides a technical solution: A cable tray for intelligent power grid wire laying, including a cable tray main body 1, a heat dissipation mechanism 2 is arranged on one side of the cable tray main body 1, and a suspension mechanism 3 is arranged on the upper side of the cable tray main body 1; The cable tray main body 1 includes a hoisting main frame 11 and a support cross beam 12 fixed inside the hoisting main frame 11. A clamping mechanism 4 is arranged inside the support cross beam 12, a support seat 13 is arranged outside the support cross beam 12, the support seat 13 is installed on the support cross beam 12 through an installation clamping frame 15, a support pressing frame 18 is arranged on one side of the installation clamping frame 15, a support screw rod 17 is fixedly installed at one end of the support pressing frame 18, one end of the support screw rod 17 is screwed with a support screw sleeve 16 through a thread, a main frame cover plate 14 is arranged on the upper side of the hoisting main frame 11, ventilation holes are arranged on the surface of the main frame cover plate 14, and the ventilation holes are equidistantly arranged on the main frame cover plate 14. A positioning protrusion is arranged on the lower side of the main frame cover plate 14. When in use, the main frame cover plate 14 is installed more stably and is convenient for ventilation and heat dissipation; The clamping mechanism 4 includes a clamping seat 41 mounted on the support crossbeam 12 and a clamping pressure column 43 slidably mounted on the upper end of the clamping seat 41. A return spring 42 is installed inside the clamping seat 41, and the lower end of the clamping pressure column 43 presses on the return spring 42. A clamping arm 44 is rotatably mounted inside the support crossbeam 12. One end of the clamping arm 44 is rotatably mounted with a clamping claw 45. A rotating guide groove 47 is formed at one end of the clamping arm 44. The lower end of the clamping pressure column 43 is fixedly installed with a rotating column 46. The clamping pressure column 43 and the clamping arm 44 are rotatably connected through the rotating column 46 and the rotating guide groove 47. The cable is pressed on the clamping pressure column 43. The clamping pressure column 43 descends and cooperates with the rotating column 46 and the rotating guide groove 47 to drive the clamping arm 44 and the clamping claw 45 to clamp on the cable, ensuring stable cable installation and facilitating equidistant separation of the cables for ventilation and heat dissipation. The shapes of the clamping arm 44 and the clamping claw 45 are both set to be V-shaped, and a limiting plate is provided at the upper end of the clamping arm 44 corresponding to the position of the clamping claw 45, which facilitates stable clamping of the cable by the clamping arm 44 and the clamping claw 45 during use. During use, the dynamic clamping with pressure self-adaptation is realized to achieve constant clamping force protection for cables with different diameters.

[0021] As can be seen from the above description, the present invention has the following beneficial effects: During use, the clamping mechanism 4 is installed through the support crossbeam 12, and the cable is assisted to be supported through the cooperation of the installation bracket 15 and the support base 13. The separated installation during installation and use can ensure ventilation and heat dissipation, and the clamping pressure column 43 presses down to drive the clamping arm 44 to rotate, so that the clamping arm 44 clamps on the cable and presses the clamping claw 45 to clamp on the cable to ensure stability.

[0022] Embodiment 2: Please refer to Figures 1 to 10 As shown in the figure, on the basis of Embodiment 1, the present invention provides a technical solution: The heat dissipation mechanism 2 includes a heat insulation plate 22 mounted on the hoisting main frame 11 and a support plate 25 mounted on the support base 13. A heat dissipation silica gel pad 21 is provided on the upper side of the support plate 25. A heat dissipation pipe 23 and heat dissipation fins 24 are installed on one side of the heat insulation plate 22, and one side of the heat dissipation fins 24 is installed on the surface of the heat dissipation pipe 23. One end of the heat dissipation pipe 23 is communicated with one end of the heat dissipation silica gel pad 21. During use, the heat dissipation silica gel pad 21 is installed on the support plate 25, and one end of the heat dissipation silica gel pad 21 is connected to the connection head 28 and the circulation pump 29 through a connecting pipe 26 and a connector 27; One end of the heat dissipation silica gel pad 21 is provided with a connecting pipe 26, one end of the connecting pipe 26 is provided with a connector 27, one end of the heat dissipation pipe 23 is installed with a circulation pump 29 through a connection head 28, and the circulation pump 29 is connected to the connecting pipe 26 through the connection head 28 and the connector 27. The upper surface of the heat dissipation silica gel pad 21 is set to be arc-shaped, and the inside of the heat dissipation silica gel pad 21 is filled with heat-conducting silicone oil. The heat dissipation pipes 23 are communicated with each other. The operation of the circulation pump 29 enables the silicone oil to flow between the heat dissipation silica gel pad 21 and the heat dissipation pipe 23 to facilitate heat absorption and dissipation, and the heat dissipation fins 24 are cooperated to accelerate heat dissipation to the outside.

[0023] Among them, when the arc-shaped design of the heat dissipation silicone pad 21 wraps the cable, the radial pressure generated by its elastic deformation forms a complement to the clamping force of the clamping claw 45. When the cable heats up and expands, the softening degree of the silicone pad due to heat is matched with the V-shaped angle (50-70°) of the clamping claw, so that the clamping force maintains a dynamic balance. At the same time, the heat-conducting silicone oil circulation system conducts part of the heat to the area of the clamping seat 41 through the spiral layout of the heat dissipation tube 23, and uses the thermal expansion and contraction effect to adjust the pre-tightening force of the return spring 42 to achieve temperature self-compensated clamping. The separated installation of the clamping mechanism forms an equidistant air duct between the cables, which constitutes a vertical convection with the ventilation holes of the main frame cover plate 14, which can increase the air flow rate and improve the heat dissipation efficiency of the heat sink 24. The hollow structure of the support cross beam 12 serves as an auxiliary air duct, and its opening direction forms a diversion angle with the limiting plate of the clamping arm 44 to guide the air flow to concentrate on passing through the cable dense area.

[0024] For the heat dissipation mechanism 2 adopting the above technical solution, during use, the heat dissipation silicone pad 21 is supported by the cooperation of the support seat 13 and the support plate 25, and the cable is supported by the heat dissipation silicone pad 21 on the support plate 25. The heat dissipation silicone pad 21 wraps the cable, absorbs the heat of the cable through the heat dissipation silicone pad 21 and the internal heat-conducting medium, and the heat-conducting medium circulates between the heat dissipation tube 23 and the heat dissipation silicone pad 21 by the operation of the circulation pump 29, so as to quickly export the heat of the cable for heat dissipation. A three-level active heat dissipation system of contact, conduction and convection is adopted, and more than 70% of the heat is taken away quickly by the directly contacting silicone pad.

[0025] Further, reference can be made to Figure 1 、 Figures 6 to 10, the suspension mechanism 3 includes a suspension rod 31 fixed to the main hoisting frame 11, a buffer seat 32 installed at one end of the suspension rod 31, and a connecting seat 33 fixed to one end of the buffer seat 32. A buffer rod 36 is installed inside the buffer seat 32. An installation groove 34 and a winding groove 35 are formed on the surface of the connecting seat 33. A suspension cable 38 is arranged inside the connecting seat 33. The suspension cable 38 passes through the connecting seat 33 and the buffer rod 36 and is wound in the winding groove 35. The hoisting installs the suspension rod 31 on the main hoisting frame 11. The suspension cable 38 passes through the connecting seat 33, the installation groove 34, and the guiding groove 37. Then one end of the suspension cable 38 is wound inside the winding groove 35, and the other end of the suspension cable 38 is hoisted at the using position; the upper end of the buffer rod 36 is slidably installed inside the buffer seat 32. A buffer guide post 361 is installed inside the buffer seat 32. One end of the buffer guide post 361 is slidably installed inside the buffer rod 36. A buffer and vibration damping mechanism 39 is arranged on the outer side of the buffer guide post 361. When being pulled forcefully, the suspension cable 38 drives the buffer rod 36 to slide inside the buffer seat 32 and compress the buffer spring 395 for buffering. At the same time, the friction between the suspension cables 38 provides damping; a through hole is arranged in the middle of the connecting seat 33. The installation groove 34 communicates with the through hole. A guiding groove 37 is formed on the surface of the buffer rod 36, and the suspension cable 38 is clamped in the guiding groove 37, which is convenient for installing and using the suspension cable 38 during use; one end of the suspension cable 38 passes through the installation groove 34 and the guiding groove 37, and one end of the suspension cable 38 is tied to the installation groove 34 and pressed on the outer side of the suspension cable 38.

[0026] The involute-shaped rotating guide groove 47 of the clamping arm 44 converts the longitudinal vibration of the suspension system into a non-linear rotational motion, and the anti-slip lines of the clamping claw 45 consume the vibration energy through friction with the surface of the cable; the self-winding friction damping of the suspension cable 38 and the return spring 42 of the clamping mechanism form a parallel damping system; when the bridge is subjected to a lateral force, the displacement of the buffer rod 36 pushes the damping ball 3981 through the guiding push plate 396, and the generated reverse force is transmitted to the cable through the clamping pressure column 43, forming a force closed-loop balance system. The V-shaped design of the clamping mechanism enables it to generate a self-tightening effect in a vibrating environment, and the greater the vibration amplitude, the greater the increase in the clamping force.

[0027] Further, reference can be made to Figure 1 , Figures 6 to 10, the buffer damping mechanism 39 includes a damping chute 392 formed on the surface of the buffer guide post 361 and a damping slider 391 slidably installed in the damping chute 392. A fixing plate 393 is fixedly installed on one side of the damping slider 391. An installation block 394 is provided on one side of the fixing plate 393. A buffer spring 395 is engaged inside the installation block 394. The fixing plate 393 drives the damping slider 391 to slide in the damping chute 392 to further provide damping and vibration reduction. The buffer damping mechanism 39 further includes a positioning plate 397 installed inside the buffer seat 32 and a guiding push plate 396 fixed to one end of the buffer rod 36. One end of the guiding push plate 396 is slidably sleeved outside the positioning plate 397. A damping seat 399 is installed on the inner wall of the buffer seat 32. A damping slide post 398 is provided at one end of the damping seat 399. A damping ball 3981 is provided at one end of the damping slide post 398. A damping push plate 3961 is provided on one side of the guiding push plate 396. The damping ball 3981 presses on the damping push plate 3961. A damping spring 3991 is provided inside the damping seat 399. One end of the damping slide post 398 presses on the damping spring 3991. The guiding push plate 396 slides outside the positioning plate 397, and the damping push plate 3961 presses on the damping ball 3981 for damping and vibration reduction. The damping slide post 398 slides to compress the damping spring 3991 to strengthen the support and buffer. The adopted multi-physical-field coupling composite damping system can dissipate the vibration energy through mechanical friction and elastic deformation in stages.

[0028] For the suspension mechanism 3 adopting the above technical solution, when in use, the bridge main body 1 is hoisted through the suspension rod 31, the suspension steel cable 38 and the connecting seat 33. During hoisting, the installation groove 34 is conveniently installed and tied through the installation groove 34 and the winding groove 35. With the buffer of the buffer damping mechanism 39, when there is a pull, friction damping and vibration reduction are carried out between the suspension steel cable 38 in the installation groove 34 and the winding groove 35, and the buffer and vibration reduction of the buffer damping mechanism 39 itself are further coordinated to reduce the phenomenon of pull damage.

[0029] Working principle and usage process of the present invention: When in use, fix the support crossbeam 12 inside the hoisting main frame 11, and install the circulation pump 29 at one end of the support crossbeam 12 and connect it to one end of the heat dissipation pipe 23. Then, install the clamping mechanism 4 equidistantly inside the support crossbeam 12 as needed. Install the support base 13 on the support crossbeam 12 through the installation bracket 15. Clamp the support pressure frame 18 on the installation bracket 15, and rotate the support screw sleeve 16 to push the support screw 17 and the support pressure frame 18 to tightly press and clamp on the installation bracket 15 to ensure stable installation. Install the support plate 25 on the support base 13, install the heat dissipation silica gel pad 21 on the support plate 25, and connect one end of the heat dissipation silica gel pad 21 to the connection head 28 and the circulation pump 29 through the connecting pipe 26 and the connection head 27. Then, place the cable on the heat dissipation silica gel pad 21. At the same time, the cable presses on the clamping pressure column 43. The clamping pressure column 43 descends and drives the clamping arm 44 and the clamping claw 45 to clamp on the cable in cooperation with the rotating column 46 and the rotating guide groove 47, ensuring stable installation of the cable and facilitating equidistant separation of the cable for ventilation and heat dissipation. At the same time, the heat dissipation silica gel pad 21 and the internal silicone oil absorb heat, and then the circulation pump 29 operates to make the silicone oil flow between the heat dissipation silica gel pad 21 and the heat dissipation pipe 23 for convenient heat absorption and dissipation, and cooperate with the heat dissipation fins 24 to accelerate heat dissipation outward. For hoisting, install the suspension rod 31 on the hoisting main frame 11. The suspension steel cable 38 passes through the connection seat 33, the installation groove 34, and the guide groove 37. Then, one end of the suspension steel cable 38 is wound inside the winding groove 35, and the other end of the suspension steel cable 38 is hoisted to the use position. When stressed and pulled, the suspension steel cable 38 drives the buffer rod 36 to slide inside the buffer seat 32 and compress the buffer spring 395 for buffering. At the same time, the friction between the suspension steel cables 38 provides damping, and the damping sliding seat 391 is driven by the fixing plate 393 to slide inside the damping chute 392 to further provide damping and vibration reduction. At the same time, the guide push plate 396 slides outside the positioning plate 397, and the damping push plate 3961 presses on the damping ball 3981 for damping and vibration reduction. The damping sliding column 398 slides to compress the damping spring 3991 to strengthen the support and buffering, thereby reducing the pulling and vibration reduction during use and reducing the phenomenon of bridge vibration damage.
