Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, and in particular relates to a reinforcement structure for cable tray hinges. Background Technology

[0002] In the field of building electrical engineering and industrial pipeline laying, cable trays are the core support structure that carries wires and ensures the stable operation of power and communication systems. Their installation stability is directly related to the safety and reliability of the entire electrical system. During service, cable trays inevitably face the dual challenges of temperature changes and building structure deformation. The core of hinged connection is to allow a certain relative displacement (such as slight expansion and contraction) at the connection parts. Its core function is to buffer stress and adapt to deformation.

[0003] When the length of a straight section of cable tray is too long, hinges need to be installed between the cable trays to offset the thermal expansion and contraction deformation caused by temperature changes and to prevent the overall structure from warping. Therefore, the stability of the hinges is crucial. Thus, a reinforced structure for cable tray hinges is needed. The hinge connection plate can be supported and wrapped by supporting angle steel and U-shaped right-angle plates, thereby improving the installation stability of the cable tray. Utility Model Content

[0013] In the following description, embodiments of the reinforcing structure of the cable tray hinge of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a reinforced structure for a cable tray hinge connector according to an embodiment of the present invention. It includes hinge connecting plates 2 disposed at the bottom of two cable trays 1. The cable trays 1 are mounted below the ceiling via a hanging bracket. A copper braided strip is installed between the two cable trays 1. A cover plate 3 is provided on the top of each cable tray 1. Three strip-shaped mounting holes 4 are provided on both the front and back of each cable tray 1. Two mounting grooves 5 are provided on both the front and back of each hinge connecting plate 2. Mounting bolts 14 are fixedly connected to both the front and back of each hinge connecting plate 2. Through the oblong hole 15, the surface of the mounting bolt 14 is provided with a matching nut. Both the front and back of the hinged connecting plate 2 are provided with rectangular plates 12. Through the cooperation of the rectangular plates 12, mounting bolts 13 and 14, and the oblong hole 15, the two oblong holes 15 on the rectangular plate 12 are aligned with mounting bolts 13 and 14 respectively, so that the rectangular plate 12 fits onto the mounting bolts 13 and 14. Then, the matching nuts are installed, but not too tightly, and further... To improve the stability of the U-shaped right-angle plate 9, two oblong holes 15 are opened on the surface of the rectangular plate 12. The hinged connecting plate 2 is installed on the surface of the cable tray 1 with bolts and nuts. Two supporting angle steels 6 are provided at the bottom of the hinged connecting plate 2, and two connecting plates 7 are fixedly installed on the top of the supporting angle steels 6. The surface of the connecting plate 7 is fixedly installed with a lifting screw 8. The top of the lifting screw 8 is fixed to the roof with an expansion bolt. The top of the hinged connecting plate 2 is provided with a U-shaped right-angle plate 9, which is in contact with the cover plate 3. The U-shaped right-angle plate 9 is located at the top of the gap between the two cover plates 3. The front and back of the U-shaped right-angle plate 9 are fixedly connected with mounting bolts 13. Mounting bolts 13 pass through the waist-shaped hole 15. The surface of mounting bolts 13 is provided with a matching nut. The U-shaped right-angle plate 9 is deformable. The surface of the U-shaped right-angle plate 9 has two waist-shaped holes 10. The front and back of the hinged connecting plate 2 are fixedly connected with mounting bolts 11. Mounting bolts 11 pass through the waist-shaped hole 10. The surface of mounting bolts 11 is provided with a matching nut.

[0015] Working principle: When using this utility model, the user places the hinged connecting plate 2 below the gap between the two cable trays 1, ensuring the hinged connecting plate 2 is tightly against the cable tray 1, and aligns the mounting groove 5 with the strip-shaped mounting hole 4. Then, one end of the matching bolt is passed through the strip-shaped mounting hole 4 and the mounting groove 5, and the matching nut is installed on the bolt. The nut should not be tightened too much; some expansion gap should be left between the nut and the hinged connecting plate 2. Then, the U-shaped right-angle plate 9 is installed above the gap between the two cover plates 3, which can effectively reduce the entry of dust and other dirt into the cable tray 1. Then, the U-shaped right-angle plate 9 is slightly pried open to make the waist-shaped... Hole 10 can be fitted onto mounting bolt 11, and then the matching nut is installed on mounting bolt 11. Again, it should not be tightened too much. At this time, the hinge connecting plate 2 and the U-shaped right angle plate 9 are used together to form a protective cover for the gap between the two cable trays 1. Then, the connecting plate 7 is installed on the pre-installed lifting screw 8, and then the supporting angle steel 6 is installed together with the connecting plate 7, so that the supporting angle steel 6 provides support and stability for the hinge connecting plate 2. This achieves the purpose of supporting and covering the hinge connecting plate through the supporting angle steel and the U-shaped right angle plate, thereby improving the installation stability of the cable tray.

[0016] In summary, this reinforced cable tray hinge structure, by installing the hinge connecting plate 2 below the gap between the two cable trays 1, and ensuring the nuts are not too tight (leaving some expansion gap between the nuts and the hinge connecting plate 2), and then installing the U-shaped right-angle plate 9 above the gap between the two cover plates 3, effectively reduces the entry of dust and other contaminants into the cable tray 1. Similarly, the nuts on the mounting bolt 11 should not be tightened too much. The combined use of the hinge connecting plate 2 and the U-shaped right-angle plate 9 forms a protective enclosure around the gap between the two cable trays 1. Furthermore, the supporting angle steel 6 provides support and stability to the hinge connecting plate 2, thus improving the stability of the cable tray installation.
