Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to an internal support reinforcement for cable trays. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) and pipe gallery supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts must be galvanized. After galvanizing, cable trays installed in the open air outside buildings are used.

[0003] To enhance the structural strength of cable trays, transverse stiffeners (crossbars) or longitudinal stiffeners are typically used as internal support reinforcements to prevent deformation, twisting, or collapse under load or external force. This is especially important in long spans, heavy loads, or special installation environments.

[0004] However, existing cable tray internal support reinforcements are usually fixed by welding or bolts, requiring special tools (such as welding machines and wrenches) for construction. Installation is time-consuming and relies on skilled workers. Moreover, operation is inconvenient in narrow spaces or at heights, prolonging the construction period. This results in complex and inefficient installation of cable tray internal support reinforcements. At the same time, the internal support reinforcements of cable trays are not adjustable, lacking flexibility. The spacing and position of the reinforcements (such as transverse support ribs) are fixed and cannot be dynamically adjusted according to the actual load. When the number or weight of cables changes, the original structure must be dismantled and reinstalled, resulting in insufficient adaptability. Welded or riveted reinforcements cannot be disassembled, and the original structure must be damaged during later maintenance or cable replacement, which increases maintenance costs and may affect the overall strength of the cable tray. Utility Model Content

[0005] To address the problems of inconvenient installation, poor adaptability, and difficult maintenance of existing cable tray internal support reinforcements mentioned in the background art, this utility model proposes a cable tray internal support reinforcement that is easy to install, highly adaptable, and convenient for later maintenance and use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cable tray internal support reinforcement, including a frame plate, side locking holes, bottom locking holes, a support plate, and mounting components. The side locking holes are symmetrically opened on both sides of the frame plate; the bottom locking holes are equidistantly opened on the bottom of the frame plate, and a limit block is inserted into the inside of the bottom locking hole; the support plate is fixedly connected to the top of the limit block, and a rib plate is welded inside the support plate; the mounting components are symmetrically installed on both sides of the support plate.

[0008] Furthermore, the limiting blocks are symmetrically installed at the bottom of the support plate, the support plate is inserted into the frame plate through the limiting blocks, and the top of the support plate has a wave-shaped structure.

[0009] Furthermore, the rib is composed of multiple rectangular plates of different lengths, and the top of the rib has an arc-shaped structure, which is fitted together with the top and bottom arc surfaces of the support plate.

[0010] Furthermore, the mounting assembly includes an insert plate, a movable strip welded to one side of the insert plate, a pull plate welded to one side of the movable strip, a limit groove formed on one side of the pull plate, a protruding plate provided on one side of the pull plate, a positioning block welded to one side of the rib plate, springs symmetrically mounted on one side of the insert plate, a limit hole formed on one side of the rib plate, and a shrinkage groove formed on one side of the support plate.

[0011] Furthermore, the insert plate is movably disposed inside the shrinkage groove, one side of the insert plate has an inclined structure, the moving strip is movably disposed inside the limiting hole, the positioning block is movably disposed inside the limiting groove, and when the limiting block is engaged inside the bottom locking hole, the insert plate is inserted into the side locking hole.

[0012] Furthermore, the pull plate is movably disposed on the outside of the rib plate, the limiting hole is opened on the rectangular plates on both sides of the rib plate, one end of the spring is fixedly connected to one side of the rib plate, and the insert plate is elastically connected to the rib plate through the spring.

[0013] Furthermore, the mounting component includes a slot, the inner wall of which is fixedly connected to a limiting strip, the outer side of which is engaged with a locking strip, the inner wall of which is fixedly connected to an insert block, and one side of which is fixedly connected to a pull ring.

[0014] Furthermore, when the limiting block is engaged inside the bottom card hole, the insert block passes through the side card hole and engages inside the card slot. The limiting strip is made of stainless steel, the card strip is made of rubber, and the card slots are symmetrically opened on both sides of the support plate.

[0015] The present invention provides an internal support reinforcement for cable trays, which has the following advantages: The installation components facilitate the installation of the support plate inside the tray using plug-in or snap-fit ​​methods, eliminating the need for installation tools and allowing for direct hand operation. This reduces the installation difficulty and efficiency of the internal support reinforcement, and also facilitates subsequent maintenance. Furthermore, the multiple side and bottom locking holes allow for easy installation of the internal support reinforcement in different positions within the cable tray according to usage requirements, thereby improving its applicability.

[0028] Example 1

[0029] See Figures 1-4 In this embodiment, the device includes a frame plate 1, side locking holes 2, bottom locking holes 3, a support plate 5, and an installation assembly 7. The side locking holes 2 are symmetrically located on both sides of the frame plate 1. The bottom locking holes 3 are equidistantly located at the bottom of the frame plate 1, and a limiting block 4 is inserted into the interior of each bottom locking hole 3. The support plate 5 is fixedly connected to the top of the limiting block 4, and the limiting block 4 is symmetrically installed at the bottom of the support plate 5. The support plate 5 is inserted into the interior of the frame plate 1 through the limiting block 4. The top of the support plate 5 has a wavy structure, and a rib plate 6 is welded inside the support plate 5. The rib plate 6 is composed of multiple rectangular plates of different lengths. The top of the rib plate 6 has an arc-shaped structure and is fitted to the top and bottom arc surfaces of the support plate 5. In use, the cable is placed on the top of the support plate 5. The wavy top surface of the support plate 5 can distribute the pressure of the cable, and the rib plate 6 increases the load-bearing capacity of the support plate 5, thereby improving the strength of the internal support reinforcement.

[0030] The mounting components 7 are symmetrically installed on both sides of the support plate 5. The side locking holes 2 are equally spaced on both sides of the frame plate 1, and the bottom locking holes 3 are equally spaced on the bottom of the frame plate 1. Two bottom locking holes 3 and four side locking holes 2 form a group, which can install one support plate 5, thereby facilitating the installation of the inner support reinforcement in the required position. At the same time, it is convenient to add or remove the inner support reinforcement according to the amount of cable used.

[0031] Mounting assembly 7 includes a mounting plate 711, one side of which has an inclined structure. A movable strip 712 is welded to one side of the mounting plate 711. When the limiting block 4 is engaged inside the bottom locking hole 3, the mounting plate 711 is inserted into the side locking hole 2. A pull plate 713 is welded to one side of the movable strip 712. The pull plate 713 is movably positioned on the outside of the rib plate 6. A limiting groove 714 is formed on one side of the pull plate 713. A protruding plate 715 is provided on one side of the pull plate 713. A positioning block 716 is welded to one side of the rib plate 6. 16 is movably disposed inside the limiting groove 714. Springs 717 are symmetrically installed on one side of the insert plate 711. One end of the spring 717 is fixedly connected to one side of the rib plate 6, and the insert plate 711 is elastically connected to the rib plate 6 through the spring 717. A limiting hole 718 is opened on one side of the rib plate 6. The limiting hole 718 is opened on the rectangular plates on both sides of the rib plate 6. The moving strip 712 is movably disposed inside the limiting hole 718. A shrinkage groove 719 is opened on one side of the support plate 5, and the insert plate 711 is movably disposed inside the shrinkage groove 719.

[0032] Specifically, in use, the limiting block 4 is directly aligned with the top of the bottom locking hole 3, and then the support plate 5 is moved vertically downward and placed inside the frame plate 1, so that the inner side wall of the frame plate 1 presses the insert plate 711. Due to the inclined surface of the insert plate 711, it is convenient to move and retract the insert plate 711 into the shrinkage groove 719 by the squeezing force. When the limiting block 4 is inserted into the bottom locking hole 3, the insert plate 711 is aligned with the side locking hole 2, so that the insert plate 711 is elastically engaged into the side locking hole 2 by the spring 717, thereby positioning and installing the support plate 5, thus making the installation of the inner support reinforcement convenient.

[0033] During later maintenance, by pinching the protruding plates 715 on both sides of the rib plate 6, the pull plate 713 is moved to the outside of the rib plate 6, and the insert plate 711 is pulled into the shrinkage groove 719 by the moving strip 712, thereby removing the insert plate 711 from the side locking hole 2, making it easy to remove the inner support reinforcement, thereby facilitating the replacement of the position of the inner support reinforcement or the increase or decrease of the number used, and improving the flexibility of the use of the inner support reinforcement.

[0034] Example 2

[0035] See Figure 5 and Figure 6In this embodiment, an installation component 7 is included. The installation component 7 includes a slot 721, which is symmetrically opened on both sides of the support plate 5. A limiting strip 722 is fixedly connected to the inner wall of the slot 721. The limiting strip 722 is made of stainless steel. A locking strip 723 is engaged on the outer side of the limiting strip 722. The locking strip 723 is made of rubber. The material of the locking strip 723 is elastic, which makes it easy to squeeze and engage it on one side of the limiting strip 722. This increases the stability of the inner support reinforcement installation through friction. An insert 724 is fixedly connected to the inner wall of the locking strip 723. When the limiting block 4 is engaged inside the bottom locking hole 3, the insert 724 passes through the side locking hole 2 and engages inside the slot 721. A pull ring 725 is fixedly connected to one side of the insert 724.

[0036] Specifically, in use, the limiting block 4 at the bottom of the support plate 5 is aligned with the bottom locking hole 3 and placed vertically. Then, the support plate 5 is placed inside the frame plate 1. When the limiting block 4 is inserted and engaged inside the bottom locking hole 3, the moving strips 712 on both sides of the support plate 5 are aligned with one side of the side locking hole 2. Then, the insert block 724 is taken out and inserted into the side locking hole 2. By pressing, the locking strip 723 can be squeezed and engaged with one side of the limiting strip 722, so that the insert block 724 is inserted and engaged inside the side locking hole 2 and the locking groove 721. This fixes the support plate 5 to the frame plate 1, which facilitates the installation of the inner support reinforcement. When disassembling the inner support reinforcement, simply pull the pull ring 725 to move the insert block 724 outward, and the support plate 5 can be easily removed from the frame plate 1, which facilitates the later maintenance of the inner support reinforcement.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
