Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a cable tray for power line wiring. Background Technology

[0002] Cable trays for power line wiring are devices used to support and fix power cables. They are usually made of metal or composite materials and have open or closed structures. They are mainly used to arrange and lay power cables in an orderly manner in buildings, substations, factories and other places. They can effectively protect cables from mechanical damage, environmental corrosion and electromagnetic interference, while facilitating the installation, maintenance and replacement of cables, and ensuring the safe and reliable operation of the power system.

[0003] Cable trays may deform, bend, or break due to external forces during use, affecting their load-bearing capacity and stability. Minor deformations can be corrected and repaired; severely damaged cable trays need to be replaced to ensure the safety and reliability of cable laying.

[0004] When it is necessary to replace the cable trays installed on the wall-mounted ceiling hangers, the cables inside the trays must first be temporarily erected and secured so that the trays can be safely removed from the hangers. After the trays are removed, the cables will be suspended in the air. If the cables are not properly managed and secured, they are prone to displacement due to gravity or external forces, which may even cause the cables in other trays that have not been removed to also shift. This phenomenon can easily damage the fixing frames inside other trays, thereby affecting the normal operation of the cables and subsequent replacement work. Therefore, a cable tray for power line wiring is proposed to address the above problems. Utility Model Content

[0029] Please see Figure 1-7 This utility model provides a technical solution:

[0030] A cable tray for power line wiring includes a tray body 1, an internal support assembly 2 fixedly connected to the inner side of the tray body 1, a tray cover plate assembly 3 fixedly connected to the upper end of the internal support assembly 2, the internal support assembly 2 including a cable arc frame 21, a support column 22 fixedly connected to the outer side of the cable arc frame 21, an expansion foot 23 fixedly connected to the end of the support column 22, a reserved screw hole 24 opened on the inner side of the support column 22, and a cable mounting groove 25 and a fixing opening 27 opened on the inner side of the cable arc frame 21. A flat-head bolt 26 is spirally fitted inside the screw hole 24. The cable tray cover plate assembly 3 includes a cable tray cover body 31. A second crimping hole 32 is opened inside the cable tray cover body 31. A reinforcing rib 33 and a sliding shell 34 are fixedly connected to the top of the cable tray cover body 31. A sliding groove 35 is opened inside the sliding shell 34. A sliding rod 36 is slidably connected inside the sliding groove 35. An internal threaded cylinder 39 is fixedly connected to the front end of the sliding rod 36. A screw 37 is spirally fitted inside the internal threaded cylinder 39. A load-bearing plate 38 is rotatably connected to the lower end of the screw 37.

[0031] As a further implementation of this solution, multiple sets of built-in support components 2 are set, with two components in each set. The built-in support components 2 are fixed together by bolts. Through the above settings, the multiple sets of built-in support components 2 can provide multi-point support for the cable, effectively disperse the weight of the cable, prevent the cable from shifting due to suspension during replacement, and ensure the stability of the cable when replacing the cable tray.

[0032] As a further implementation of this solution, a first crimping hole 4 is provided on the inner side of the cable tray body 1, the outer side of the flat-head bolt 26 is fitted with the inner side of the first crimping hole 4, and the inner side of the second crimping hole 32 is fitted with the upper flat-head bolt 26. Through the above arrangement, the built-in support assembly 2 can be fixed simultaneously with the cable tray body 1 and the cable tray cover body 31, so as to facilitate the replacement of the cable tray distribution in the future.

[0033] As a further implementation of this solution, the bottom end of the cable tray cover body 31 is fitted with the upper expansion foot 23, the lower end of the cable tray body 1 is fitted with the lower expansion foot 23, and the top end of the cable tray body 1 is fitted with the bottom end of the cable tray cover body 31. Through the above settings, a stable support structure is formed. This tightly fitted structure can effectively disperse the weight of the cable.

[0034] As a further implementation of this solution, a gap is provided between the front end of the sliding shell 34 and the front end of the cable tray cover body 31. Slide bars are fixedly connected to the left and right sides of the slide rod 36. The slide rod 36 is embedded in the interior of the sliding shell 34. Through the above arrangement, the gap design between the front end of the sliding shell 34 and the front end of the cable tray cover body 31 leaves space for supporting other load-bearing plates 38.

[0035] As a further implementation of this solution, the length of the slide rod 36 is twice the length of the slide shell 34. A storage groove is provided on the inner side of the slide rod 36 near the support plate 38. The support plate 38 is installed inside the storage groove of the slide rod 36. A threaded hole is provided on the inner side of the internal threaded cylinder 39. A rotating plate is fixedly connected to the lower end of the screw 37. A rotating hole is provided at the upper end of the support plate 38. The rotating plate of the screw 37 is embedded and installed inside the support plate 38. A rotating handle is fixed at the upper end of the screw 37. With the above settings, this design can support the suspended cable by the support of the support plate 38 when replacing the cable tray body 1, preventing the suspended cable from falling and displacing from other cable trays, thus improving the safety when replacing the cable tray.

[0036] Workflow: When replacing the installed cable tray, first replace the cable tray cover assembly 3. Remove the front part of the flat-head bolts 26 installed inside the second crimping hole 32, and then directly lift the cable tray cover body 31. Install the intact cable tray cover assembly 3, aligning the second crimping hole 32 of the cable tray cover body 31 with the reserved screw hole 24 at the upper end. Then fix the cable tray cover body 31 to the upper support 22 using the flat-head bolts 26. After fixing, replace the cable tray body 1. Before replacing the cable tray body 1, remove all the flat-head bolts 26 installed inside the first crimping hole 4 of the cable tray body 1. Push the screw 37 to move the sliding rod 36 to the front end of the cable tray body 1, so that the front end of the sliding rod 36 protrudes from the front end of the cable tray body 1. At the same time, the load-bearing plate 38 is on top of another cable tray cover body 31. Turn the handle at the upper end of the screw 37. The screw 37 rotates inside the internal threaded cylinder 39. At this time, the screw 37 drives the support plate 38 to move downward. When the support plate 38 is in close contact with the upper end of another cable tray cover body 31, the same operation is performed on the other screws 37. At this time, the cable tray cover body 31 can be supported. At the same time, the cable tray cover body 31 supports the second crimping hole 32 fixed at the lower end. The reinforcing rib 33 can improve the strength of the cable tray cover body 31 and prevent the cable tray cover body 31 from bending when supporting the cable. At this time, the bolts connecting the cable tray body 1 to other cable tray bodies 1 are removed, and the cable tray body 1 can be pulled out from the hanger, so that the intact cable tray body 1 can be replaced. During this process, multiple sets of built-in support components 2 support the cable, which can prevent the cable from shifting due to being suspended inside other cable trays, avoid damage to the internal fixing structure of other cable trays, and ensure the safety of cable tray replacement.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
