Description

Technical Field

[0001] The utility model relates to the technical field of bridge design, and particularly to a steel structure bridge. Background Art

[0002] A cable tray is a metal structure used to run cables and wires. It usually consists of a series of parallel metal troughs that are used to contain the cables, protect them from physical damage, and keep them away from external interference such as dust, moisture, and other factors that may affect the performance of the cables. Cable trays are widely used in industrial, commercial, and residential buildings for wiring and electrical systems.

[0003] Existing bridges are mostly integrated structures when laid. When the length of the bridge is too long or too short, welding and cutting are required to change the length of the bridge, which increases the working time and is inconvenient for bridge transportation. At the same time, the bridge is usually laid indoors or outdoors. When laid outdoors, the probability of the bridge being damaged by external forces will increase, and the existing bridge has weak protection against external force impacts and cannot well protect the cables placed in the bridge.

[0004] Therefore, a steel structure bridge is proposed. Utility Model Content

[0028] Specifically, Figures 1 to 4 As shown, the bridge assembly 1 is provided with multiple groups, and the multiple groups of bridge assembly 1 are connected by connecting plates 4 and connecting slots 5. The upper slide plate 2 is provided with multiple groups, and the number of groups of the upper slide plate 2 is the same as that of the bridge assembly 1. The inner upper end of the bridge assembly 1 is provided with a bottom plate 13, and the upper end of the bottom plate 13 is fixedly connected to the lower end of the support platform 6. The support platform 6 is matched with the support plate 7 and the bottom plate 13 to form an "I" shape. The bottom plate 13 is fixedly connected to the inner upper end of the bridge assembly 1 by multiple groups of screws.

[0029] During operation, according to the required length, multiple groups of bridge components 1 are connected together through the connecting plate 4 and the connecting groove 5, the upper slide plate 2 is slidably connected to the upper end of the bridge component 1, and the bottom plate 13 is fixed to the inner upper end of the bridge component 1 by screws. The upper end of the bottom plate 13 is fixed with the support platform 6 and the support plate 7. The support platform 6, the support plate 7 and the bottom plate 13 are arranged in the middle of the bridge component 1 to support the lower end of the bridge component 1 and the upper end of the upper slide plate 2. Then, the assembled bridge is fixedly installed on the wall or other fixed objects through the upper end of the fixing plate 3. Finally, when the staff conducts daily inspections of the cables in the bridge, the slide The cable condition inside the bridge frame assembly 1 can be observed by moving the upper slide plate 2. By setting a connecting mechanism, the bridge frame body is assembled by multiple groups of bridge frame assemblies 1, and can be assembled according to the required bridge frame length, which saves working time and is more convenient for the transportation of the bridge frame. The setting of the upper slide plate 2 is convenient for the staff to inspect and repair the cables set inside the bridge frame assembly 1. A support platform 6 is set. When the upper slide plate 2 is impacted by external force, the support plate 7 and the bottom plate 13 fixedly connected at the upper and lower ends of the support platform 6 support and buffer the upper slide plate 2 and the bridge frame assembly 1, thereby reducing the possibility of damage to the cables inside the bridge frame assembly 1.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, multiple groups of first adjustment grooves 8 are arranged on the front and rear sides of the lower end of the support plate 7, and the first extrusion spring 9 is fixedly connected inside the first adjustment groove 8.
