Fig. 3 is a partially enlarged view of a portion a in fig. 1.
The codes in the figure are respectively: 1 is the support axle sleeve, 2 is the support horizontal pole, 3 is the fixed bolster, 4 is the connecting rod, 5 is the thermal expansion spare, 6 is fixed axle sleeve, 7 is the cable, 8 is the metal support pole, 9 is the strong point, 33 is the gas storage chamber.
Detailed Description
As shown in fig. 1, the cable fireproof support comprises a fixed support 3, wherein more than one supporting cross rod 2 is arranged on the fixed support 3 through screws, one side of the fixed support 3 is fixedly arranged on the inner wall of a cable well through more than one screw, more than one supporting point 9 is welded at the upper end of each supporting cross rod 2 side by side, the upper end surface of each supporting point 9 is provided with a jack, and a metal supporting rod 8 is inserted into each jack;
A supporting shaft sleeve 1 is all sleeved at the top of the metal supporting rod 8, an arc-shaped concave cavity is formed in the upper end face of the supporting shaft sleeve 1, the bottom of each cable 7 is placed in the arc-shaped concave cavity, a clearance cavity is formed between every two adjacent cables 7, a thermal expansion assembly is arranged in the clearance cavity, the two sides of the thermal expansion assembly are in contact with the cables 7 and the metal supporting shaft sleeve 1 at the bottom, as shown in figure 3, the cables on the two sides are mutually ejected after the thermal expansion assembly is heated, and the distance of the clearance cavity between every two adjacent cables is increased.
As shown in fig. 2, the thermal expansion components all include a connecting rod 4, the bottom of the connecting rod 4 is welded and fixed on the supporting cross rod 2, the top of the connecting rod 4 is integrally provided with a fixed shaft sleeve 6, the upper end surface of the fixed shaft sleeve 6 is provided with an installation cavity, a thermal expansion piece 5 is arranged in the installation cavity, and the top of the thermal expansion piece 5 extends upwards and contacts with the two sides of the cable.
In this embodiment, each thermal expansion member comprises a hollow rubber member, a gas storage cavity 33 is formed in the middle of the hollow rubber member, and the gas storage cavity 33 is filled with inert gas. In this embodiment, the inert gas is a mixed gas in which nitrogen, argon, and carbon dioxide are mixed in proportion. Because the thermal expansion piece is filled with inert gas, in case there is flame around, can make the thermal expansion piece damaged, inside inert gas can be followed the damaged discharge, can be full of surrounding air like this to drive away oxygen, utilize the inert gas of environmental protection, to its operation of putting out a fire, get rid of the flame on the cable fast, prevent the diffusion of flame, consequently, use very safely.
In addition, if the heat between the cables is too high, the heat of the cables can be transmitted to the thermal expansion piece, the whole thermal expansion piece is expanded by utilizing the principle that the gas inside the thermal expansion piece is heated and expanded, so that the cable which is originally close to the thermal expansion piece can be spread under the action of the thermal expansion piece, the distance of a gap cavity between the adjacent cables is increased, and after the gap is spread, the cable has good heat dissipation performance and can prevent the heat between the two adjacent cables from being transmitted.
In this embodiment, the metal support rod 8 is made of an elastic metal material. Because metal support 8 all adopts elastic metal material, therefore the cable sets up in the upper end can be random puts, can be random when receiving shearing and extrusion complete deformation, effectively resists the impact, uses as the bolster, can realize warping after the thermal expansion piece is heated the inflation simultaneously and crooked, increases the interval between two adjacent strands of cables.
The invention has the beneficial effects that: the cable is supported by more than one metal support rod, the bottom of the cable can be suspended in the air, the heat dissipation performance of the whole cable is improved, and the cable has very good compression resistance and shear resistance due to the elastic metal support rods, so that the cable is effectively prevented from being damaged after being installed by external force;
Secondly, because the thermal expansion pieces are filled between the cables, when the temperature of the cables is high, the internal gas of the cables is heated to expand, or the whole thermal expansion piece is expanded, so that the cables on two sides are jacked open, gaps between the cables are increased, and the transmission of a fire source or a heat source between the cables is prevented, so that the safety is improved.
