Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray with an internal fixing mechanism. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They are composed 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. Cable trays installed outdoors are also classified as such.

[0003] Chinese patent document CN114268060A discloses a cable tray with internal cable fixing function, including a housing, a cover plate fitted on the top of the housing, L-shaped hanging plates fixedly connected to both sides of the housing, a hanging mechanism movably connected to both sides of the cover plate, and support rails fixedly connected to both sides of the inner wall of the housing, with sliding seats fitted on the surface of the support rails. This invention has the advantages of separating and fixing cables, facilitating cable assembly and disassembly, and providing dehumidification protection for cables. It solves the problems of existing cable trays having a simple structure, lacking internal cable fixing mechanisms, resulting in cables being haphazardly placed inside the cable tray, easily tangled, prone to short circuits if cables are damaged, thus damaging electrical equipment, inconvenient for cable fixing and disassembly, and unable to dehumidify the cables, allowing excessive moisture to seep into the cables and reducing their lifespan.

[0004] The existing technology described above cannot quickly limit and lock the cable reel, nor can it safely and stably control and adjust its lifting. Therefore, it is necessary to develop a cable tray with an internal fixing mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cable tray with an internal fixing mechanism to solve the problems mentioned in the background art, such as the inability to quickly limit and lock the cable reel, and the inability to safely and stably control and adjust its lifting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable tray with an internal fixing mechanism, including a cable reel, wherein a limiting sleeve is fixedly installed at the center of both ends of the cable reel, a rotating shaft assembly is installed inside the limiting sleeve, a hollow sleeve is welded and fixed to one end of the limiting sleeve, and the interior of the hollow sleeve is fixedly connected to the rotating shaft assembly through a limiting pin, and sturdy support members are installed on both sides of the bottom of the cable reel.

[0007] Preferably, the hollow sleeve and the rotating shaft assembly are provided with insertion holes at corresponding positions on their surfaces, and the limiting pin is connected to the insertion holes.

[0008] Preferably, two bearing assemblies are installed below the rotating shaft assembly, and the two ends of the bearing assemblies are connected to bearing seats via movable shafts.

[0009] Preferably, a fixed guide post is installed below the bearing housing, and a fixed sleeve is installed at the lower end of the fixed guide post.

[0010] Preferably, a triangular support frame is welded and fixed to the side surface of the fixing sleeve, and a support base is fixedly connected to the fixing sleeve through the triangular support frame.

[0011] Preferably, a hydraulic support cylinder is installed on the stabilizing support member, and the upper end of the hydraulic support cylinder is fixedly connected to the lower end surface of the fixed sleeve through a hydraulic rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model features a conveniently assembled and fixed limiting sleeve structure, which facilitates the limiting and fixing of the rotating shaft components at both ends of the cable reel, thereby locking the rotating shaft components and securing the cable reel. Simultaneously, it provides stable lifting and lowering control for the bottom of the cable reel, allowing for quick and easy adjustment of the cable reel's installation height. Furthermore, it offers advantages such as good support and protection, and high structural installation stability. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-3 An embodiment of this utility model provides: a cable tray with an internal fixing mechanism, including a cable reel 9, with limiting sleeves 8 fixedly installed at the center of both ends of the cable reel 9, a rotating shaft assembly 7 installed inside the limiting sleeve 8, a hollow sleeve 14 welded to one end of the limiting sleeve 8, the interior of the hollow sleeve 14 being fixedly connected to the rotating shaft assembly 7 through a limiting pin 13, and sturdy support members 2 installed on both sides of the bottom of the cable reel 9.

[0020] Furthermore, the hollow sleeve 14 and the rotating shaft assembly 7 are provided with corresponding insertion holes on their surfaces. The limiting pin 13 is connected to the corresponding insertion hole structure, which facilitates quick locking between the rotating shaft assembly 7 and the hollow sleeve 14 to prevent the rotating shaft assembly 7 from rotating.

[0021] Furthermore, two bearing assemblies 11 are installed below the rotating shaft assembly 7. The two ends of the bearing assembly 11 are connected to the bearing seats 6 through the movable shaft 10, which facilitates the control of the bearing assembly 11 to rotate, thereby causing the rotating shaft assembly 7 to rotate on the bearing assembly 11.

[0022] Furthermore, a fixed guide post 5 is installed below the bearing housing 6, and a fixed sleeve 4 is installed at the lower end of the fixed guide post 5. A triangular support frame 1 is welded and fixed to the side surface of the fixed sleeve 4. The fixed sleeve 4 is fixedly connected to a support base through the triangular support frame 1, which is used to provide stable support and protection for the upper bearing housing 6 and improve the safety and stability of the cable reel 9.

[0023] Furthermore, a hydraulic support cylinder 3 is installed on the stabilizing support 2. The upper end of the hydraulic support cylinder 3 is fixedly connected to the lower end surface of the fixed sleeve 4 through the hydraulic rod 12. Under the drive of the hydraulic support cylinder 3, the hydraulic rod 12 is driven to push the fixed sleeve 4 upward, thereby enabling rapid control and adjustment of the installation height of the cable reel 9.

[0024] Working principle: During use, limit sleeves 8 are fixedly installed at the center of both ends of the cable reel 9. A rotating shaft assembly 7 is installed inside the limit sleeve 8.

Stable support members 2 are installed on both sides of the bottom of the cable reel 9. Hydraulic support cylinders 3 are installed on the stable support members 2. The upper end of the pressure support cylinder 3 is fixedly connected to the lower end surface of the fixed sleeve 4 via a hydraulic rod 12. Driven by the hydraulic support cylinder 3, the hydraulic rod 12 is driven to press the fixed sleeve 4 upward, thereby allowing for rapid control and adjustment of the installation height of the cable reel 9. Two bearing assemblies 11 are installed below the rotating shaft assembly 7. The two ends of the bearing assembly 11 are connected to bearing seats 6 via movable shafts 10. A fixed guide post 5 is installed below the bearing seat 6. A fixed sleeve 4 is installed at the lower end of the fixed guide post 5. A triangular support frame 1 is welded and fixed to the side surface of the fixed sleeve 4. A support base is fixedly connected to the fixed sleeve 4 via the triangular support frame 1, which is used to provide stable support and protection for the upper bearing seat 6, thereby improving the safety and stability of the cable reel 9.
