Description

Technical Field

[0001] The utility model belongs to the technical field of cable trays, and more specifically, particularly relates to a flame-retardant and fire-proof cable tray. Background Art

[0002] A cable is usually a cable similar to a rope formed by stranding several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a center. The whole is wrapped with a highly insulating covering layer. It is mostly erected in the air or installed underground or underwater for telecommunications or power transmission. A cable tray is an essential object for erecting cables. Cable trays are divided into trough type, tray type, ladder type, grid type and other structures.

[0003] Based on the above, the inventor found the following problems: Most of the existing fire-proof cable trays can effectively prevent fire and retard flame, but the connection between the cable trays is usually assembled by patches and rivets. When a certain section of the cable tray is damaged, it needs to be disassembled as a whole, which will cause unnecessary losses. At the same time, the wires in the cable tray are directly placed inside the cable tray, and it is inevitable that they will be in a mess, which is not convenient for later maintenance.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a flame-retardant and fire-proof cable tray is provided with the aim of achieving a more practical value. Content of the Utility Model

[0005] The purpose and effect of a flame-retardant and fire-proof cable tray of the utility model are achieved by the following specific technical means:

[0006] A flame-retardant and fire-proof cable tray includes a cable tray body. The cable tray body is composed of a "C"-shaped trough and a cover plate. A through-hole groove is penetrated through one outer wall of the "C"-shaped trough. A clamping component is installed on the other outer wall of the "C"-shaped trough, and a pair of adjacent cable tray bodies are assembled and installed through the clamping component and the through-hole groove.

[0007] Further, the clamping component includes a fixed block installed on the outer wall of the "C"-shaped trough. An installation groove is opened on the side wall of the fixed block. A limiting groove is opened in the installation groove. A trapezoidal protruding block is slidably installed between the limiting grooves, and a spring is installed on one side of the trapezoidal protruding block located in the installation groove.

[0008] Further, an assembly groove is opened at the bottom of the "C"-shaped trough. A fixing plate is installed in the assembly groove through a sliding block. A rectangular groove is opened at the top of the fixing plate.

[0009] Further, a partition plate is inserted and installed in the rectangular groove. A conical rubber seat is installed at the bottom end surface of the partition plate, and the shape of the conical rubber seat is matched with the shape inside the rectangular groove.

[0010] Furthermore, both the "C"-shaped groove frame and the cover plate are made of metal materials, and galvanized layers are coated on the surfaces of the "C"-shaped groove frame and the cover plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Through the cooperation of the fixing block, installation groove, trapezoidal raised block, spring and through-hole groove, when a pair of adjacent bridge frames need to be installed, the fixing block is inserted into the through-hole groove. At this time, the trapezoidal raised block is squeezed by the inner wall of the through-hole groove so that the trapezoidal raised block can contract into the installation groove. After being inserted to a certain position, the trapezoidal raised block is forced by the reaction force of the spring to be engaged in the through-hole groove, thus completing the assembly of adjacent bridge frames. When disassembling, just operate in the reverse direction. Through the above operations, convenient disassembly and installation can be achieved, greatly improving the overall assembly efficiency.

[0013] 2. Through the use of the assembly groove, fixing plate, rectangular groove and partition board, when the partition board is inserted into the corresponding rectangular groove, effective partitioning inside the bridge frame can be realized. By clamping different types of lines in the corresponding partitions, classification operations can be achieved. Through the above operations, it is convenient for subsequent maintenance and detection. BRIEF DESCRIPTION OF THE DRAWINGS

A trapezoidal protrusion block 5 is slidably installed between the limiting grooves. One side of the trapezoidal protrusion block 5 located in the installation groove is provided with a spring 6. Through the cooperation of the fixing block 7, the installation groove, the trapezoidal protrusion block 5, the spring 6 and the through-hole groove 4, when a pair of adjacent cable trays need to be installed, the fixing block 7 is inserted into the through-hole groove 4. At this time, the trapezoidal protrusion block 5 is squeezed by the inner wall of the through-hole groove 4 so that the trapezoidal protrusion block 5 can be contracted into the installation groove. After being inserted to a certain position, the trapezoidal protrusion block 5 is forced by the reaction force of the spring 6 to be clamped in the through-hole groove 4, thereby completing the assembly of adjacent cable trays. When disassembling, just operate in the reverse direction. Through the above operations, convenient disassembly and installation can be achieved, greatly improving the overall assembly efficiency.

[0027] Among them, an assembly groove 3 is formed at the bottom of the "C"-shaped groove frame 1. A fixing plate 8 is installed in the assembly groove 3 through a sliding block. A rectangular groove 9 is formed at the top of the fixing plate 8. By using the assembly groove 3, the fixing plate 8, and the rectangular groove 9 in cooperation with the partition plate 10, when the partition plate 10 is inserted into the corresponding rectangular groove 9, effective partitioning inside the cable tray can be achieved. By clamping different types of cables in the corresponding partitions, classification operations can be realized. Through the above operations, subsequent maintenance and inspection are facilitated.

[0029] Among them, both the "C"-shaped groove frame 1 and the cover plate 2 are made of metal materials, and galvanized layers are coated on the surfaces of the "C"-shaped groove frame 1 and the cover plate 2. Through the design of the galvanized layer, the overall corrosion resistance and oxidation resistance of the cable tray body can be increased, and the overall service life of the cable tray body can be extended.

[0030] Specific usage method and function of this embodiment:

[0031] When using this type of cable tray, first align adjacent cable trays, and then insert the fixing block 7 into the through-hole groove 4. Through the cooperation of the fixing block 7, the installation groove, the trapezoidal protruding block 5, and the spring 6 with the through-hole groove 4, when adjacent cable trays need to be installed, insert the fixing block 7 into the through-hole groove 4. At this time, the trapezoidal protruding block 5 is squeezed by the inner wall of the through-hole groove 4 so that the trapezoidal protruding block 5 can contract into the installation groove. After being inserted to a certain position, the trapezoidal protruding block 5 is forced by the reaction force of the spring 6 to be clamped in the through-hole groove 4, thus completing the assembly of adjacent cable trays. When disassembling, just operate in the reverse direction. Through the above operations, convenient disassembly and installation can be achieved, greatly improving the overall assembly efficiency. At the same time, for the convenience of later maintenance, by using the assembly groove 3, the fixing plate 8, and the rectangular groove 9 in cooperation with the partition plate 10, when the partition plate 10 is inserted into the corresponding rectangular groove 9, effective partitioning inside the cable tray can be achieved.
