Description

Technical Field

[0001] This application belongs to the field of cable tray technology, specifically a fireproof cable tray that is easy to inspect and maintain. Background Technology

[0002] Fire-resistant cable trays are facilities used to prevent cable fires caused by external fires or internal faults from spreading and to prevent the spread of fire. These trays are typically made of fire-resistant or flame-retardant materials such as fiberglass, metal, and concrete. The trays are lined with insulating blocks or plates, and the ends and joints are sealed with fire-resistant materials to form fire-resistant sections. Even if the cables inside the tray catch fire, the limited air inside makes ignition unlikely. They have a wide range of applications, generally used for fire separation in areas with dense cable distribution, such as overhead cables, cable tunnels, cable interlayers, and cable shafts, to prevent the spread of fire and to provide fireproof (or fire-resistant) separation for important cable circuits. Furthermore, fire-resistant cable trays have significant practical value; they not only serve as cable laying channels, allowing for unified cable routing and easy maintenance, but also as pathways for fire protection facilities, improving the fire safety of buildings. Therefore, fire-resistant cable trays are widely used in building design and decoration.

[0003] For example, CN222966654U discloses a fireproof cable tray that is easy to maintain. It includes an upper box and a lower box, with the lower box attached to the upper box. A connecting component is provided between the upper and lower boxes, and the upper box is connected to the lower box via the connecting component. By rotating a handle through the connecting component, a limiting block drives a rotating rod to rotate within the movable chamber and the connecting block. This causes the rotating rod to twist a torsion spring until the limiting block aligns with the limiting groove. Then, the connecting block slides off the rotating rod, and the lower box slides its insert block out of the slot, thus achieving the purpose of disassembling the lower box. This facilitates the maintenance of cables within the lower and upper boxes, allowing workers to disassemble the fireproof cable tray without tools, reducing the difficulty of disassembling and assembling the fireproof cable tray, and further improving the efficiency of cable maintenance.

[0004] However, in this application, the slot box is generally fixed to the wall or the ground, while the height-adjustable bracket design is convenient for different installation environments. Utility Model Content

[0005] The purpose of this application is to provide a fireproof cable tray that is easy to inspect and maintain, in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: a fireproof cable tray that is easy to maintain, including an upper box body and a lower box body. The lower box body is provided below the upper box body. Four fixing plates are fixedly provided on the outer surfaces of both sides of the lower box body. Threaded posts are threaded to the surface of the fixing plates. Fastening nuts one and two are threaded to the two sides of the fixing plates respectively. A support plate is fixedly provided at one end of the threaded posts at the bottom of the lower box body.

[0007] By adopting the above technical solution, the adjustable mounting bracket allows the slot box to be adjusted and installed according to different installation environments. The fixing plate fixed on the outside of the lower box body facilitates the fixing of the support plate and threaded post to the outside of the upper and lower box bodies. At the same time, by rotating the first and second fastening nuts, when the support plate and the lower box body are at a suitable distance, the first and second fastening nuts are fixed to the two ends of the fixing plate, thereby fixing the structural component and facilitating subsequent installation work.

[0008] In a preferred embodiment, a slot is provided at the connection between the lower box and the upper box, and a plug is provided inside the slot.

[0009] By adopting the above technical solution, and with the slots and inserts provided on the inner walls of the upper and lower boxes, the structure can be made to reinforce the fixation of the upper and lower boxes.

[0011] By adopting the above technical solution, the groove opened on the surface of the fixing block facilitates the limiting and fixing of the upper and lower boxes by the structural component.

[0012] In a preferred embodiment, a connecting rod is movably disposed on the surface of the fixed block, and a rotating rod is disposed inside the movable chamber of the connecting rod, and a torsion spring is disposed on the surface of the rotating rod.

[0013] By adopting the above technical solution, the fixed movable compartment, together with the fixed block and the internal rotating rod and torsion spring, can make the upper box and the lower box fixedly connected or open.

[0014] In a preferred embodiment, a throttle is fixedly provided at the top end of the connecting rod, and two limiting blocks are fixedly provided on the top surface of the connecting rod.

[0015] By adopting the above technical solution, the throttle is designed to facilitate the rotation of components such as connecting rods by the staff, while the limit block can fix or open the structure.

[0016] In a preferred embodiment, the upper and lower boxes are provided with clamping plate grooves inside, two sliding rods are fixedly provided on one side surface of the clamping plate grooves, and a connecting plate is fixedly connected to the surface of the two sliding rods. A handle is fixedly provided on the extended end surface of the connecting plate.

[0017] By adopting the above technical solution, workers can hold the handle and use the connecting plate to move the slide rod, which facilitates the sliding of the clamping plate slot and the placement of cables.

[0018] In a preferred embodiment, a slide cylinder is movably disposed on the other end surface of the slide rod, and a spring is disposed inside the slide cylinder, and the spring is fixedly disposed on the inner surface of the upper box.

[0019] By adopting the above technical solution, the spring can be used to allow the slide rod to slide inside the slide cylinder or return to its original position, thereby performing clamping work.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, an adjustable mounting bracket is provided to allow the slot box to be adjusted and installed according to different installation environments. With the fixed plate fixed on the outside of the lower box body, the support plate and threaded post can be easily fixed to the outside of the upper and lower box bodies. At the same time, by rotating the first and second fastening nuts, when the support plate and the lower box body are at a suitable distance, the first and second fastening nuts are fixed to the two ends of the fixed plate, thereby fixing the structural component and facilitating subsequent installation work.
