Detailed implementation manners
[0032] 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, and the examples are shown in the accompanying drawings. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or the same kind of elements.
[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0034] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.
[0035] Example 1, please refer to Figure 1 and Figure 2 , a flexible adaptation type U-shaped steel cable tray is provided, including a cable tray base 1, a U-shaped steel bracket 3, a cable turnover rack 4, and a cable support bracket 5 installed on the cable tray base 1; the U-shaped steel bracket 3, the cable turnover rack 4, and the cable support bracket 5 are successively erected on the tabletop of the cable tray base 1, and an adjustment track 2 is provided on the tabletop of the cable tray base 1. The cable turnover rack 4 is installed on the adjustment track 2 and is docked between the U-shaped steel bracket 3 and the cable support bracket 5. The U-shaped steel bracket 3 includes a support frame 31 and a U-shaped steel branch bracket 32 erected on the support frame 31; the cable turnover rack 4 includes a vertical bracket 41, a lifter 42 erected on the vertical bracket 41, a turnover frame 43 provided at the driving end of the lifter 42, and a limit bar 44 installed inside the turnover frame 43. The bottom end of the frame of the vertical bracket 41 is installed on the adjustment track 2, and the limit bar 44 is docked with the end of the U-shaped steel branch bracket 32.
[0036] The cable support bracket 5 includes a base 51, a support frame substrate 52, and a deflection bracket 57 installed on the base 51. A support frame 54 is installed at the top of the support frame substrate 52, and a wiring support plate 59 is provided on the support frame 54. A deflection support plate 58 is provided on the deflection bracket 57. The wiring support plate 59 is docked with the limit bar 44, and the deflection support plate 58 is further docked with the deflection bracket 57. A jacking frame 53 is provided at the bottom of the base 51, and the support frame substrate 52 is supported and installed at the lifting end of the jacking frame 53 to adjust the support height of the wiring support plate 59. A fixing frame 55 is installed on the base 51, and the deflection bracket 57 is installed on the fixing frame 55 through a lateral pushing frame 56 to laterally adjust the position of the deflection bracket 57, that is, to adjust the distance between the deflection bracket 57 and the wiring support plate 59.
[0037] This embodiment is designed as a modular adaptation structure design. Through the combination of the adjustment track 2 and the vertical bracket 41, the slidable adjustment of the cable turnover rack 4 on the cable tray base 1 is realized, forming a three-section modular architecture of the U-shaped steel bracket 3 - cable turnover rack 4 - cable support bracket 5. A three-dimensional adjustment system is formed among the modules by the lifter 42, the jacking frame 53, and the lateral pushing frame 56, and multi-dimensional position adjustment can be performed in the vertical direction (lifter 42 / jacking frame 53), horizontal direction (adjustment track 2), and longitudinal direction (lateral pushing frame 56).
[0038] This embodiment also designs a dynamic cable guiding mechanism. Through the precise docking of the limit bar 44 and the U-shaped steel branch support 32, combined with the secondary guiding design of the deflecting support plate 58, a two-stage cable steering protection system is formed. The lifting compensation function of the turnover frame 43 can absorb the longitudinal displacement during cable traction to avoid excessive bending. The horizontal adjustment ability of the deflecting bracket 57 can adapt to different corner requirements. To further protect the cable, the cable support bracket 5 in this embodiment is a composite support system, using the U-shaped steel branch support 32 as the main load-bearing structure, and cooperating with the auxiliary support of the support frame 54 to form a mechanical transmission path with clear primary and secondary. The combined design of the jacking frame 53 and the fixed frame 55 realizes height adjustment while maintaining the support stability, ensuring that the cable bending radius always meets the standard requirements.
[0039] Embodiment 2. Please refer to Figure 1 and Figure 3 , based on the content described in the above embodiment, for the specific implementation structure of the U-shaped steel support 3, this embodiment is designed as follows:
[0040] The support frame 31 includes a support rod 311 and a support frame 312 installed on the support rod 311. The U-shaped steel branch support 32 includes a linear plate 321 installed on the inner wall of the support frame 312 and an installation groove 322 provided on the linear plate 321. A wire-passing U-shaped steel 323 is installed in the installation groove 322. The installation groove 322 on the linear plate 321 adopts a standardized snap connection design, and the wire-passing U-shaped steel 323 is quickly installed and uninstalled through a dovetail groove or a T-bolt. The replacement time of a single U-shaped steel is ≤ 30 seconds. The installation groove spacing is distributed according to a 50mm modulus to adapt to different cable density requirements (5 - 20 cables / meter).
[0041] A rotating shaft 313 is provided at the tail end of the support frame 312, and a wire-supporting roller 314 is provided on the shaft body of the rotating shaft 313. The wire-supporting roller 314 is docked with the wire-passing U-shaped steel 323. By providing the rotating shaft 313 and the wire-supporting roller 314 at the tail end of the support frame 312, a dynamic rolling contact surface is formed. When the cable passes through the wire-passing U-shaped steel 323, it is in rolling friction contact with the wire-supporting roller 314, greatly reducing the cable traction resistance.
[0042] A limit pressing piece 315 is also installed at the top of the support frame 312, and the limit pressing piece 315 is pressed above the wire-supporting roller 314. The limit pressing piece 315 covers above the wire-supporting roller 314 to form a semi-closed guiding channel, which allows the cable to slide freely while restricting its vertical displacement (±2mm), avoiding cable derailment or excessive bending.
[0043] Embodiment 3. Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6Based on the contents of the above embodiment, the specific implementation structure of the cable turnover rack 4 is designed as follows:
[0044] The vertical support 41 includes a vertical support rod 411 and a top frame plate 412 installed on both sides of the vertical support rod 411. The bottom end of the top frame plate 412 is installed on the adjustment track 2 through a slider. The lifting mechanism 42 includes a driving cylinder 421 installed on the vertical support rod 411 and a driving rod 422 arranged at the driving end of the driving cylinder 421. The periphery of the turnover frame 43 is provided with a lifting slide 413, and the lifting slide 413 is inserted into the through hole of the vertical support rod 411. In this embodiment, the slider on the adjustment track 2 is linked with the driving cylinder 421 to achieve the composite movement of the lateral movement (±200mm) and vertical lifting (stroke 300mm) of the turnover frame 43. The lifting slide 413 cooperates with the through hole of the vertical support rod 411 to form a four-point guide structure, and the lifting inclination error is ≤0.5° / m.
[0045] The main body of the turnover frame 43 is a main frame 431, and the limiting fence 44 includes a first wire clamping fence 441 and a second wire clamping fence 442 arranged at the bottom of the inner frame of the main frame 431. The first wire clamping fence 441 and the second wire clamping fence 442 are independently installed in the frame of the main frame 431 through a fine adjustment shaft 443. The main frame 431 is provided with a first gear driving member 432 for driving the first wire clamping fence 441 and a second gear driving member 433 for driving the second wire clamping fence 442. The first wire clamping fence 441 and the second wire clamping fence 442 both include a wire clamping fence upper plate 444 and a wire clamping fence lower plate 445. The first gear driving member 432 and the second gear driving member 433 are driven by a worm gear, and can accurately adjust the clamping angles of the first wire clamping bar 441 and the second wire clamping bar 442 (adjustment accuracy ±0.5°), and the double bars are clamped collaboratively: the first wire clamping bar 441 and the second wire clamping bar 442 are independently controlled by the fine-tuning shaft 443, and can form a symmetrical or asymmetrical clamping mode, which is suitable for the mixed layout of a single large-diameter cable or multiple small cables.
[0046] In one case of this embodiment, a movable ball 446 is arranged between the upper plate 444 of the clamping bar and the lower plate 445 of the clamping bar. The movable balls 446 on the first clamping bar 441 and the second clamping bar 442 are arranged in a staggered manner. The movable balls 446 are made of zirconium oxide ceramics to contact the side edge of the cable. The movable balls 446 are arranged in a staggered manner (axial spacing 20mm, radial stagger angle 15°), forming a spiral contact track, converting the cable sliding friction into rolling friction, and reducing the friction coefficient to 0.02-0.05.
[0047] Example 4, please refer to Figure 2 , Figure 7 and Figure 8, based on the content described in the above embodiments, for the specific implementation structure of the support bracket 5, this embodiment is designed as follows:
[0048] The jacking frame 53 includes a bottom frame 531, a jacking cylinder 532 installed on the bottom frame 531, and a jacking pillar 533 disposed at the driving end of the jacking cylinder 532. A limit sleeve 534 is provided on the base 51, and the rod body of the jacking pillar 533 is supported within the limit sleeve 534 and fixed within the jacking pillar fixing seat 521 of the support frame substrate 52. Flanking slider 522 is installed at both ends of the support frame substrate 52, and the flanking slider 522 is slidably installed on the flanking slide bar 511. In this embodiment, the jacking cylinder 532 realizes the vertical lifting of the support frame substrate 52 through the sliding cooperation between the jacking pillar 533 and the limit sleeve 534. The limit sleeve 534 is embedded with a self-lubricating copper sleeve, and the friction coefficient is as low as 0.08 to ensure smooth lifting. The flanking sliders 522 on both sides of the support frame substrate 52 adopt a double-track sliding design to form a four-point constraint mechanism.
[0049] The support frame 54 includes a flanking frame plate 541 installed on the frame of the support frame substrate 52 and a concave frame 542 disposed on the flanking frame plate 541. A lower concave interval 543 is formed between the concave frames 542 at both ends, and the wiring support plate 59 is installed on the lower concave interval 543.
[0050] The fixing frame 55 is disposed on the front and rear sides of the base 51. The lateral pushing frame 56 includes fixing plates 561 installed on the fixing frames 55 on both sides. A lateral pushing support rod 562 is provided between the fixing plates 561. The steering bracket 57 is installed at the rod end of the lateral pushing support rod 562. The lateral pushing frame 56 further includes an internal driving rod 563 for driving the steering bracket 57 to move.
[0051] The concave frame 542 adopts an arc transition structure to evenly disperse the gravity of the cable to the two flanking frame plates 541 on both sides, improving the single-point load-bearing capacity. The internal driving rod 563 drives the steering bracket 57 to move along the lateral pushing support rod 562 through ball screw transmission, and the lateral adjustment range is ±200 mm. The double fixing plate 561 structure forms a rigid frame, and the lateral stiffness is increased to 200 N / μm.
[0052] In this embodiment, a multi-degree-of-freedom linkage adjustment mechanism is designed. Through the linkage of the vertical lifting (Z-axis) of the lifting frame 53 and the horizontal displacement (X-axis) of the lateral pushing frame 56, precise alignment of the direction-changing pallet 58 and the wiring pallet 59 in three-dimensional space is achieved. The combination of the stroke (±150 mm) of the lifting cylinder 532 and the displacement (±200 mm) of the lateral pushing rod 562 can cover the distance range (50 - 350 mm) required for cable turning. A conical guide groove (with an inclination angle of 15°) is provided at the contact end of the direction-changing pallet 58, and an elastic coil spring (with a spring stiffness coefficient of 5 N / mm) is configured at the end of the wiring pallet 59 to automatically compensate for the position deviation of ±10 mm during docking, ensuring smooth cable transition.
[0053] This embodiment can further enhance the adaptability to complex scenarios. The three-dimensional linkage adjustment supports non-planar wiring and can cover complex working conditions such as wiring around the columns in the computer room and misalignment of the wall-piercing holes between equipment rooms. This design performs outstandingly in scenarios such as cross-cabinet wiring in large data centers and dynamic cable supply for factory automation equipment. Actual measurements show that in a project with 200 turning nodes, adopting this structure can shorten the cable installation cycle by 50%, reduce the rework rate caused by poor docking from 12% to less than 1%, and save more than 30% of the total life cycle cost.
