Description

Technical Field

[0001] The utility model belongs to the technical field of cable installation support, in particular to a convenient and detachable cable trench fireproof bracket. Background Art

[0002] The cable trench support is a structure that supports and fixes the cable in the cable trench. It is usually made of metal materials and has certain strength and corrosion resistance. The cable trench support can be used in industries such as electricity, communications, and transportation. Its function is to fix the cable support in a specified position. It plays an important role in the cable laying and maintenance process, reducing the risk of the cable being squeezed, damaged or broken. In addition, in order to prevent the spread of fire in the cable trench, an isolation structure is generally provided in the cable trench to prevent the cable fire from spreading to each other. The Chinese patent with application number CN201820425793.5 discloses a drawer-type layer-by-layer isolated insulated composite cable support, including a fixed column, a plurality of brackets and a plurality of fireproof drawer-type isolation panels. The brackets are installed on the fixed columns at intervals. The fireproof drawer-type isolation panel is L-shaped, one end is inserted between two adjacent brackets, and the other end is used to form a blockage for the cable to prevent the cable fire between layers from spreading to each other when a fire occurs, effectively improving the fireproof performance. In actual use, thinner cables may sag and bend, and abut against the part of the fireproof drawer-type isolation board between the support arms, causing the fireproof drawer-type isolation board to bear a certain weight, making it inconvenient to pull out the fireproof drawer-type isolation board. At the same time, after the fireproof drawer-type isolation board is pulled out, the cable may sag further and form an obstruction when the waterproof drawer-type isolation board is reinserted, making it inconvenient to reinsert the waterproof drawer-type isolation board.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0022] like Figure 1-3 As shown, this embodiment provides a convenient and detachable cable trench fireproof support, which includes a column 1 and a bracket 2. The column 1 is vertically fixed on the cable trench side wall 11, and multiple brackets 2 are arranged at equal intervals along the length direction of the cable trench. Multiple brackets 2 are arranged at equal intervals along the length direction of the column 1, and each bracket 2 is perpendicular to the cable trench side wall 11. At the same time, the number of brackets 2 arranged on each column 1 is the same and corresponds one to one. The brackets 2 located on the same horizontal plane form a layer of support structure, and the brackets 2 located on different horizontal planes cooperate to form a multi-layer support structure. The cables are laid on each bracket 2 located on the same horizontal plane.

[0023] Specifically, refer to Figure 1 and Figure 2 A fireproof bottom plate 3 is arranged between two adjacent brackets 2 located on the same horizontal plane, and a fireproof side plate 4 is inserted between the ends of two adjacent brackets 2 located on the same horizontal plane away from the column 1. The fireproof bottom plate 3 is arranged horizontally, one side of the fireproof bottom plate 3 is in contact with the side wall of the cable trench, and the two sides of the fireproof bottom plate 3 close to the bracket 2 are in contact with the bracket 2. Multiple fireproof bottom plates 3 are combined to form a horizontal isolation surface, thereby isolating cables on different layers. At the same time, refer to Figure 2 and Figure 3 The fireproof side plate 4 is vertically arranged and located on the side of the fireproof bottom plate 3 away from the cable trench side wall 11. The fireproof side plate 4 and the fireproof bottom plate 3 together form an L-shaped structure. The fireproof side plate 4 is located on the side of the cable. Multiple fireproof side plates 4 cooperate with the cable trench side wall 11 to form a vertical isolation surface on both sides of the cable to isolate the cable. The fireproof bottom plate 3 and the fireproof side plate 4 cooperate with the cable trench side wall 11 to isolate cables of different layers from multiple dimensions, preventing the fire between adjacent layers from spreading to each other, and effectively improving the fireproof performance.

[0024] Reference Figure 1 and Figure 3 , support plates 7 are provided on the side walls of two adjacent brackets 2 located on the same horizontal plane, and both ends of the fireproof bottom plate 3 are set on the support plates 7. The support plates 7 and the fireproof bottom plate 3 cooperate to form a complete isolation surface between the two adjacent brackets 2 to ensure the fireproof effect. And the setting mode of setting also improves the convenience of setting and disassembling the fireproof bottom plate 3.

[0025] Further, refer to Figure 1 and Figure 3 , mounting fasteners 5 are provided on the side walls of two adjacent brackets 2 located in the same horizontal plane that are close to each other, and the mounting fasteners 5 are located at the end of the bracket 2 away from the side wall 11 of the cable trench. The mounting fasteners 5 have a U-shaped structure, and the U-shaped openings of the mounting fasteners 5 on the two adjacent brackets 2 are arranged opposite to each other, and the two mounting fasteners 5 cooperate to form a vertical plug-in interface for the fireproof side panel 4 to be inserted from above.

[0026] The fireproof side panel 4 includes a main body 41 and a plug-in portion 42. The plug-in portion 42 is formed at the bottom of the main body 41, and the plug-in portion 42 is smaller than the main body 41 in the horizontal direction. The two are combined to form a T-shaped plate body. The plug-in portion 42 is plugged into the plug interface, and when the plug-in portion 42 is plugged into the plug interface, the main body 41 abuts against the top of the support arm 2.

[0027] In addition, refer to Figure 1 and Figure 3A relief space 10 is formed between the upper and lower fireproof side panels 4 for the lower fireproof side panel 4 to be pulled out from the plug interface. When the plug-in portion 42 is pulled out upward from the plug interface, the main body 41 is located in the relief space 10 and moves upward to avoid the movement of the fireproof side panel 4. The fireproof side panel 4 can be installed and removed conveniently by plugging and matching with the plug interface. Moreover, by setting the relief space 10, any fireproof side panel 4 can be flexibly removed as needed to inspect and repair the cables there, without having to pull out the fireproof bottom panel 3, which greatly improves the convenience of operation.

[0028] In order to facilitate the installation of support plates 7 and mounting fasteners 5 on both sides of the support arm 2, the support arm 2 is preferably a square steel pipe, which has a stable structure and low cost. Figure 1 and Figure 3 An isolation plate 8 is provided between two adjacent brackets 2 located on the same horizontal plane, and both ends of the isolation plate 8 are fixed to the top of the bracket 2. The isolation plate 8 is used to support the cables on the bracket 2, and forms an isolation cavity with the fireproof bottom plate 3 to keep the cables straight and at a certain distance from the fireproof bottom plate 3. The isolation plate 8 can prevent the cables from directly contacting the fireproof bottom plate 3, reduce the heat transfer of the cables in the adjacent layers, improve the heat dissipation and fireproof performance, and prevent the cables from bending and sagging in the gap between the two adjacent brackets 2, making the cables straighter and neater, and more convenient for cable maintenance.

[0029] Further, refer to Figure 3 A blocking plate 9 is provided between the main bodies 41 of two adjacent fireproof side panels 4 located on the same horizontal plane, and the blocking plate 9 is fixed on one of the main bodies 41. The blocking plate 9 is used to fill the gap between the main bodies 41 of the two adjacent fireproof side panels 4 to form a complete isolation surface. In this embodiment, the blocking plates 9 are sequentially fixed on the same side of the main bodies 41 of each fireproof side panel 4.
