Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a cable tray with cable fire protection and isolation function. 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] Existing cable trays mostly adopt a hollowed-out structure. When the cable catches fire, the fire source can spread directly through the hollowed-out holes and the cable, making it impossible to effectively isolate and control the fire source. They lack fire protection function and have poor fire resistance, which affects the fire-resistant use of cable trays. Therefore, we propose a cable tray with cable fire isolation function. Utility Model Content

[0004] The purpose of this invention is to provide a cable tray with fireproof isolation function for cables, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable tray with cable fireproof isolation function, comprising a cable tray housing and a cable tray cover, wherein the cable tray cover is snapped onto the cable tray housing;

[0006] The inner side of the cable tray housing is provided with several cable fixing components that are evenly distributed, and the cable fixing components are used to support and fix the cable body.

[0007] Fireproof isolation components are provided on the inner sides of both ends of the cable tray housing and the cable tray cover. The two fireproof isolation components are used to isolate and protect the cables inside the cable tray housing and the cable tray cover from fire.

[0008] Preferably, the cable fixing assembly includes a base plate, a lower clamping plate, an upper clamping plate, a locking clamp, and a locking bolt;

[0009] The base plate is located at the bottom inner side of the cable tray housing. The base plate is provided with an adjustment slot. The lower clamping plate is movably mounted on the base plate via a clamping block. The locking clamp is movably engaged on the base plate at the position corresponding to the lower clamping plate. The upper clamping plate is located inside the locking clamp via a locking bolt. The locking clamp has a threaded hole that matches the locking bolt.

[0010] Preferably, the lower clamping plate and the upper clamping plate are aligned vertically, and the cable body is disposed between the lower clamping plate and the upper clamping plate.

[0011] Preferably, the upper plate and the locking bolt are rotatably connected by a rotating seat.

[0012] Preferably, the inner side of the cable tray housing is provided with a first limiting groove that is adapted to the base plate, and the base plate is engaged in the first limiting groove.

[0013] Preferably, both the lower and upper card plates are arc-shaped card plates made of polytetrafluoroethylene material.

[0014] Preferably, the fireproof isolation component includes a lower fireproof isolation frame, an upper fireproof isolation frame, and an adjustable fireproof plate;

[0015] The inner ends of the cable tray housing are provided with second limiting grooves. The lower fireproof isolation frame and the upper fireproof isolation frame are both snapped into the second limiting grooves, and the upper fireproof isolation frame is aligned and snapped onto the lower fireproof isolation frame.

[0016] Both the lower and upper fireproof isolation frames have guide adjustment grooves on their inner sides. The upper part of the adjustable fireproof plate is set in the guide adjustment groove on the upper fireproof isolation frame through guide posts and compression springs, and the lower part of the adjustable fireproof plate is set in the guide adjustment groove on the lower fireproof isolation frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model provides fire-resistant isolation components on the inner sides of both ends of the cable tray housing and the cable tray cover. When the cable inside the cable tray housing and the cable tray cover catches fire, the fire-resistant isolation components at both ends isolate the burning cable inside the cable tray housing and the cable tray cover, preventing the spread of fire. After the cable sheath melts, the semi-circular groove at the bottom of the adjustable fireproof plate moves downward according to the change of the cable outer diameter. Through the compression spring, the adjustable fireproof plate is guided downward along the guide post in the guide adjustment groove inside the cable tray housing and the cable tray cover to press the cable. This makes the adjustable fireproof plate and the lower fireproof isolation frame tightly wrap around the burning cable, preventing the fire source from continuing to spread along the cable between the adjustable fireproof plate and the lower fireproof isolation frame, thus improving the fire-resistant isolation performance of the cable tray and enhancing the safety and reliability of the cable tray.

[0031] Fire-resistant isolation components 5 are provided on the inner sides of both ends of the cable tray housing 1 and the cable tray cover 2. These two fire-resistant isolation components 5 are used to isolate and protect the cables inside the cable tray housing 1 and the cable tray cover 2 from fire. Each fire-resistant isolation component 5 includes a lower fire-resistant isolation frame 501, an upper fire-resistant isolation frame 502, and an adjustable fire-resistant plate 503. Second limiting grooves 102 are provided at both ends of the inner side of the cable tray housing 1. The lower fire-resistant isolation frame 501 and the upper fire-resistant isolation frame 502 are both engaged within the second limiting grooves 102, with the upper fire-resistant isolation frame 502 aligned with the locking mechanism. It is placed on the lower fireproof isolation frame 501; both the lower fireproof isolation frame 501 and the upper fireproof isolation frame 502 have guide adjustment grooves 504 on their inner sides.
