DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1 to Figure 4 The flame-retardant bridge frame that can be used in a petrochemical base shown in the figure includes a first frame 1 and a second frame 2, both of which are L-shaped and parallel, and a horizontal plate 3 is arranged between the first frame 1 and the second frame 2, one end of the horizontal plate 3 is fixedly connected to the first frame 1, and the other end of the horizontal plate 3 is fixedly connected to the second frame 2, and the horizontal plates 3 are arranged in plurality, and the plurality of horizontal plates 3 are distributed at equal distances. A plurality of horizontal plates 3 are arranged between the first frame 1 and the second frame 2, so that the bottom of the bridge frame forms a hollow structure, which is beneficial to the heat dissipation of the cables laid inside the bridge frame; at the same time, the cooperation of the plurality of horizontal plates 3 makes the cable placement more stable.

[0022] Considering the multiple dangerous goods in the petrochemical base, in order to improve the safety performance of the bridge frame, a slide groove 4 is provided inside the horizontal plate 3, and a sliding channel 6 is provided on the upper surface of the horizontal plate 3. The sliding channel 6 is connected to the slide groove 4, and the width of the sliding channel 6 is smaller than the width of the slide groove 4. A slider 5 is slidably connected inside the slide groove 4, and a threaded block 7 is provided inside the sliding channel 6, and the threaded block 7 is fixedly connected to the top of the slider 5. A threaded sleeve 8 is threadedly matched on the threaded block 7, and the outer diameter of the threaded sleeve 8 is smaller than the width of the sliding channel 6. A rotating column 9 is fixedly connected to the top of the threaded sleeve 8, and the diameter of the rotating column 9 is greater than the width of the sliding channel 6. Specifically, the threaded sleeve 8 is docked with the threaded block 7, and then the slider 5 is driven to slide inside the slide groove 4 by the threaded sleeve 8 and the threaded block 7, and the fixed position of the rotating column 9 is adjusted to meet different usage requirements. After the adjustment is completed, the rotating column 9 is rotated. Due to the cooperation between the threaded block 7 and the threaded sleeve 8, the rotating column 9 moves downward and abuts on the upper surface of the horizontal plate 3, and the slider 5 abuts on the inner wall of the slide groove 4, completing the positioning of the rotating column 9. After the positioning of multiple rotating columns 9 is completed, cables of different types can be separated to avoid the cables being intertwined, and cables of different types can be separated and placed according to their heat generation to prevent cables with higher heat generation from affecting other cables in the bridge, thereby improving the safety performance of the bridge.

[0023] When the rotating column 9 needs to be moved again, the rotating column 9 is rotated in the reverse direction and positioned again according to the above steps.

[0024] In specific use, multiple sets of threaded blocks 7, threaded sleeves 8 and rotating columns 9 can be arranged on the horizontal plate 3, so as to separate multiple types of cables at the same time, especially in petrochemical bases, which have many types of cables.

[0025] In order to improve the efficiency of separating and placing cables, a separation component is provided on the rotating column 9, and the separation component includes a ring sleeve 10 and a partition 13, and two partitions 13 are provided. The ring sleeve 10 is plugged into the rotating column 9, and the partition 13 is fixedly connected to the outer wall of the ring sleeve 10, and the two partitions 13 are symmetrically distributed about the axis of the ring sleeve 10. When the partition 13 is installed, its length direction is consistent with the length direction of the bridge. The separation component is provided, and the separation component is installed on the rotating column 9 in a plug-in manner, so that cables of different models can be better separated.

[0026] The partition assembly can be selectively installed to improve the flexibility of use. The partition 13 is made of heat-insulating material, which can be used but not limited to rock wool material, and has excellent heat insulation and fireproof properties. In addition, in order to improve the flame retardant performance of the bridge, the first frame 1, the second frame 2 and the cross plate 3 are all provided with a fireproof coating, which can improve the overall fire resistance and flame retardant ability of the bridge, slow down the propagation speed of the flame, or prevent combustion within a certain period of time.

[0027] In order to improve the stability of the use of the partition 13, a slot 11 is opened on the inner ring of the ring sleeve 10. The slots 11 are distributed along the axial length direction of the ring sleeve 10. A clamping strip 12 is fixedly connected to the outer wall of the rotating column 9. The clamping strip 12 is distributed along the axial length direction of the rotating column 9, and the clamping strip 12 is plugged into the slot 11. When the ring sleeve 10 is plugged into the rotating column 9, the clamping strip 12 is inserted into the inside of the slot 11 to prevent the partition 13 from rotating at will. Considering that after the partition 13 is installed, its length direction is consistent with the length direction of the bridge, the pitch of the threaded sleeve 8 and the threaded block 7 can be reasonably set in the specific production process, so that after the rotating column 9 is positioned, the clamping strip 12 faces one of the ends of the bridge, so that after the partition 13 is installed, its length direction is consistent with the length direction of the bridge (refer to Figure 1 ), which facilitates the laying of cables.

[0028] A plurality of first heat dissipation holes 14 are formed on the side wall of the first frame 1, and a plurality of second heat dissipation holes 15 are formed on the side wall of the second frame 2. The first heat dissipation holes 14 and the second heat dissipation holes 15 are provided to improve the heat dissipation performance of the bridge as a whole.
