Description

Technical Field

[0001] This utility model relates to the field of cable tray support technology, and in particular to a high load-bearing capacity cable tray support formed by compression molding. Background Technology

[0002] High-load-bearing capacity cable tray supports, molded in one piece, are structural components used to support and fix cable trays. They are crucial for supporting cable trays and maintaining structural stability, and are widely used in basements, factories, pipe racks, and other locations where cables are concentrated. Especially in basement environments, due to limited space, a large number of cables, and long tray spans, multiple trays often need to be placed on the support to meet wiring requirements, thus placing higher demands on the support's load-bearing capacity.

[0003] While existing cable tray supports provide basic structural support, they still exhibit significant structural deficiencies in practical engineering applications, particularly in heavy-load wiring environments such as basements, large building electrical shafts, or industrial plants. These environments typically require multiple cable tray units to accommodate complex cable distribution needs. In this arrangement, the support bears not only the weight of the single-layer cable tray itself but also the weight of numerous power and low-voltage cables laid within, resulting in a multiplied overall weight. Since existing cable tray supports are not structurally designed to withstand such multi-layered concentrated loads, the total weight of the cable tray inevitably concentrates in the central area of ​​the support after installation—the middle section of the cable tray span. Prolonged exposure to this concentrated downward pressure easily leads to stress concentration in this area, causing significant sagging, bending deformation, or even breakage of the cable tray structure. This not only causes cable misalignment and loosening but may also damage the cable insulation due to excessive stretching or compression, potentially triggering electrical faults. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a high load-bearing capacity cable tray support by molding, so as to solve the problem that the existing cable tray supports have not been reinforced in structural design for this multi-layer concentrated load condition, resulting in obvious sinking, bending deformation or even breakage of the cable tray structure.

[0005] To achieve the above objectives, this utility model provides a high-load-bearing capacity cable tray support formed by molding, comprising a load-bearing rod, with fixing rods fixedly connected to both sides of the top of the load-bearing rod, mounting pads fixedly connected to the top of the fixing rod, and multiple equidistant and evenly distributed trough-type cable trays placed on the top of the load-bearing rod. A connecting plate is fixedly connected between the opposite faces of two fixing rods. A load-bearing mechanism for enhancing the load-bearing capacity of the load-bearing rod is provided between the bottom of the load-bearing rod and the bottom end of the fixing rod. The load-bearing mechanism includes fixing blocks fixedly connected to both sides of the bottom of the two fixing rods, two load-bearing limiting plates fixedly connected to both sides of the bottom of the load-bearing rod, and collars fixedly connected to both sides of the two load-bearing limiting plates. A load-bearing pull rope is fixedly connected between the opposite faces of the fixing blocks on both sides of the bottom of the two fixing rods, and the outer wall of the load-bearing pull rope penetrates the inner wall of the collar.

[0006] Preferably, a fastener is fitted between the middle parts of the two load-bearing ropes. The fastener is U-shaped, and threaded rods are fixedly connected to both ends of the fastener. A tightening block is slidably connected to the outer wall of the threaded rod, and an internal threaded ring is threaded to the outer wall of the threaded rod.

[0007] Preferably, the tightening block has a receiving groove on the side near the load-bearing rope, and the receiving groove is arc-shaped and adapted to the outer wall of the load-bearing rope.

[0008] Preferably, a fixing plate is fixedly connected between the inner walls of the multiple equidistant and evenly distributed trough-type cable trays, and multiple equidistant and evenly distributed pull rings are fixedly connected between the top of the fixing plate and the side wall of the pull ring, and a connecting rope is fixedly connected between the pull rings on the fixing plate and the pull rings on the connecting plate.

[0009] Preferably, concave support plates are fixedly connected to both sides of the bottom of the support rod near the fastener.

[0010] Preferably, when the two load-bearing ropes are inside the fastener, the two load-bearing ropes are V-shaped.

[0011] The beneficial effects of this utility model are:

[0012] 1. This high-load-bearing capacity cable tray support, manufactured using a molding process, utilizes two fixed rods installed at the top of the basement as a foundation support. The support rods are then horizontally connected below them, and load-bearing ropes, collars, concave support plates, and fixing blocks are installed below the support rods, forming a composite force-bearing structure of "upper pressure and lower pull." This effectively counteracts the concentrated downward pressure generated in the middle of the cable trays by multiple trough-type cable trays and their cable loads. Simultaneously, the fastener structure, featuring threaded rods, internal threaded rings, and adjustable tightening blocks, allows for precise control of the tension of the symmetrical load-bearing ropes, further enhancing the bending resistance and overall load-bearing capacity of the support rods. This prevents the trough-type cable trays from sinking, bending, or even breaking under heavy-load concentrated conditions, significantly improving the mechanical stability and service life of the support, ensuring the safe operation of the cable system, and offering advantages such as reasonable structure, stable installation, and strong load-bearing capacity.

[0023] like Figures 1 to 5 As shown, a high-load-bearing cable tray support molded by compression molding includes a load-bearing rod 1. Fixing rods 2 are fixedly connected to both sides of the top of the load-bearing rod 1. Mounting pads 3 are fixedly connected to the top of the fixing rods 2. Multiple equidistant and evenly distributed trough-type cable trays 4 are placed on the top of the load-bearing rod 1. A connecting plate 5 is fixedly connected between the opposing surfaces of two fixing rods 2. A load-bearing mechanism for strengthening the load-bearing capacity of the load-bearing rod 1 is provided between the bottom of the load-bearing rod 1 and the bottom end of the fixing rod 2. The load-bearing mechanism includes fixing blocks 6 fixedly connected to both sides of the bottom of the two fixing rods 2, and two load-bearing limiting plates fixedly connected to both sides of the bottom of the load-bearing rod 1. 7. Both sides of the two load-bearing limit plates 7 are fixedly connected with collars 8. The two fixed blocks 6 on both sides of the bottom of the two fixed rods 2 are fixedly connected with load-bearing pull ropes 9. The outer wall of the load-bearing pull ropes 9 penetrates the inner wall of the collars 8. The middle part of the two load-bearing pull ropes 9 is fitted with fasteners 10. The shape of the fasteners 10 is U-shaped. Both ends of the fasteners 10 are fixedly connected with threaded rods 11. The outer wall of the threaded rods 11 is slidably connected with tightening blocks 12. The outer wall of the threaded rods 11 is threadedly connected with bearing rods 1. When the two load-bearing pull ropes 9 are inside the fasteners 10, the shape of the two load-bearing pull ropes 9 is V-shaped.

[0024] When the load-bearing mechanism is used in practice, it is first necessary to pre-position and drill holes on the top of the basement floor slab. Then, the two fixing rods 2 are installed at the drilled positions by fitting the mounting pads 3 together. The fixing rods 2 are then firmly anchored to the top structure of the basement by the externally installed expansion bolts, thus providing a stable installation foundation for the subsequent cable tray load-bearing structure.

[0025] After the two fixed rods 2 are installed, the bearing rod 1 is horizontally fixed between the bottom ends of the two fixed rods 2 to form a horizontal support frame for supporting multiple trough-type cable trays 4 installed on it. Then, the load-bearing pull rope 9 passes through the collars 8 set on both sides of the cable tray and the concave support plate 18 located below the bearing rod 1 in sequence, and is fixedly connected to the side wall of the fixing block 6 at the other end. When the load-bearing pull rope 9 is tightened, an upward pulling force can be applied below the bearing rod 1, thereby forming a counterforce between downward gravity and upward tension in the structure, which significantly improves the overall bending stiffness and load-bearing capacity of the bearing rod 1.

[0026] To achieve adjustable and continuously enhanced tension of the load-bearing rope 9, a fastener 10 for adjustment is further provided. The fastener has threaded rods 11 at both ends, and a tightening block 12 is fitted between the outer walls of the threaded rods 11. By rotating the internal threaded ring 13 located on one side of the fastener 10, the tightening block 12 can be continuously squeezed and pressed inward, thereby clamping and stretching the load-bearing rope 9. When the two load-bearing ropes 9 move inward under the action of the tightening block 12 and generate a large tension, the load-bearing rope 9 applies a stronger upward supporting force to the load-bearing rod 1, ultimately forming a good structural compensation effect and significantly improving the bending resistance of the load-bearing rod 1.

[0027] This load-bearing mechanism uses two fixed rods 2 and a load-bearing rod 1 installed at the top of the basement as basic supports. A load-bearing pull rope 9, a collar 8, a concave support plate 18, and a fixing block 6 are installed below the load-bearing rod 1, forming a composite force-bearing structure of "upper pressure and lower pull." This effectively counteracts the concentrated downward pressure generated in the middle of the cable trays 4 and their cable loads. Simultaneously, the fastener structure 10, consisting of a threaded rod 11, an internal threaded ring 13, and an adjustable tightening block 12, tightens the load-bearing pull rope 9, further enhancing the bending resistance and overall load-bearing capacity of the load-bearing rod 1. This avoids problems such as central sinking, bending deformation, or even breakage of the cable tray under heavy-load concentrated conditions, significantly improving the mechanical stability and service life of the support, ensuring the safe operation of the cable system, and possessing beneficial effects such as reasonable structure, stable installation, and strong load-bearing capacity.

[0028] Further, see attached document. Figure 5 As shown, the tightening block 12 has a receiving groove 14 on the side near the load-bearing rope 9. The receiving groove 14 is arc-shaped and fits the outer wall of the load-bearing rope 9. The design of the receiving groove 14 can accommodate the trough-type cable tray 4 and increase the contact area between the load-bearing rope 9 and the tightening block 12, so as to avoid the load-bearing rope 9 from breaking when tightening.

[0029] Further, see attached document. Figure 1As shown, a fixing plate 15 is fixedly connected between the inner walls of multiple equidistant and evenly distributed trough-type cable trays 4. Multiple equidistant and evenly distributed pull rings 16 are fixedly connected between the top of the fixing plate 15 and the side wall of the pull ring 16. A connecting rope 17 is fixedly connected between the pull rings 16 on the fixing plate 15 and the pull rings 16 on the connecting plate 5. By setting the connecting rope 17 between the side wall of the fixing plate 15 and the connecting plate 5, tension can be provided at both ends of the trough-type cable tray 4, avoiding the weight of the trough-type cable tray 4 from being completely applied to the top of the bearing rod 1, thus increasing the bearing capacity of the trough-type cable tray 4.

[0030] Further, see attached document. Figure 5 As shown, concave support plates 18 are fixedly connected to both sides of the bottom of the support rod 1 near the fastener 10. The concave support plates 18 support the load-bearing rope 9, making it easier for the fastener 10 and the tightening block 12 to tighten.
