DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0020] The cable bridge is composed of a bracket, a support arm and installation accessories; it can be erected independently or laid on various buildings (structures) and pipe gallery brackets, and has the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts need to be galvanized. The bridge installed in the open air outside the building, if it is near the seaside or belongs to a corrosion zone, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion and high impact strength. The FRP bridge provided by the utility model is conveniently fixed by setting a first FRP bridge 1 and a second FRP bridge 2, and it is easy to install. The first FRP bridge 1 and the second FRP bridge 2 can be fixed by plugging them into each other. When disassembling, you only need to pull the plug rod 6 outward and then pull the second FRP bridge 2 out of the first FRP bridge 1.

[0021] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a conveniently fixed FRP bridge frame, comprising a first FRP bridge frame 1 and a second FRP bridge frame 2, the second FRP bridge frame 2 is inserted into the first FRP bridge frame 1, slots 9 are provided on both sides of the inner walls of the first FRP bridge frame 1, plug blocks 3 are fixed on both sides of the second FRP bridge frame 2, the plug blocks 3 are inserted in the slots 9, and a connecting groove 11 is provided on the side of the plug block 3 away from the second FRP bridge frame 2, connecting members 4 are fixed on both sides of the first FRP bridge frame 1, an installation groove 12 is provided inside the connecting member 4, a sliding connection limit member passes through the installation groove 12, the limit member is inserted in the connecting groove 11, a movable plate 14 is fixed to the outer wall of the limit member, the movable plate 14 is slidably connected in the installation groove 12, a spring 13 is fixed between the movable plate 14 and the inner wall of one side of the installation groove 12, and the spring 13 is located on the outside of the limit member. The limiting member includes an insertion rod 6 that passes through and is slidably connected in the installation groove 12. The limiting member also includes a limiting block 10 fixed on the side of the insertion rod 6 close to the insertion block 3. The limiting block 10 is inserted into the connecting groove 11. The limiting block 10 and one side of the insertion block 3 are both in an inclined state. One side of the limiting block 10 contacts one side of the insertion block 3. The movable plate 14 is fixed on the outer wall of the insertion rod 6.

[0022] It should be noted that by pulling the insertion rod 6 outward, the spring 13 is compressed, the movable plate 14 slides in the installation groove 12, and the limit block 10 moves out of the connecting groove 11. At this time, the second FRP bridge frame 2 can be extracted from the first FRP bridge frame 1 to achieve disassembly. In addition, when it is necessary to fix the second FRP bridge frame 2 and the first FRP bridge frame 1, the second FRP bridge frame 2 is aligned with the first FRP bridge frame 1 and inserted so that the plug block 3 is inserted into the slot 9. During the insertion process, the limit block 10 contacts the surface of the plug block 3, and as the plug block 3 continues to go deeper, the spring 13 is squeezed, and the movable plate 14 slides in the installation groove 12 until the limit block 10 is located on one side of the connecting groove 11. The spring 13 is no longer squeezed, driving the limit block 10 to be inserted into the connecting groove 11, thereby achieving fixation between the second FRP bridge frame 2 and the first FRP bridge frame 1, which is more convenient to fix and easy to disassemble.

[0023] like Figure 1 and Figure 2 As shown, a groove 8 is provided on the side of the connector 4 away from the first FRP bridge 1, and the plug rod 6 passes through the groove 8. A connecting rod 7 is fixed to the outer wall of the plug rod 6, and the connecting rod 7 is located in the groove 8. The inner wall and the outer wall of the first FRP bridge 1 are both installed with a first flame retardant plate 15, and the inner wall and the outer wall of the second FRP bridge 2 are both installed with a second flame retardant plate. Reinforcement strips 5 are fixed to the bottom of both sides of the second FRP bridge 2 for reinforcing the bottom of both sides of the second FRP bridge 2.

[0024] It should be noted that the insertion rod 6 is limited by the connecting rod 7, and it is convenient for the staff to move the insertion rod 6 by pulling the connecting rod 7. In addition, the first flame retardant plate 15 and the second flame retardant plate are arranged to provide sufficient fire retardancy, and the two sides of the second fiberglass bridge frame 2 are protected and reinforced by the reinforcement strips 5.

[0025] Working principle: During use, when the first FRP bridge frame 1 and the second FRP bridge frame 2 are damaged, the connecting rod 7 is pulled to move the plug rod 6, and the plug rod 6 moves outward, so that the spring 13 is compressed, the movable plate 14 slides in the installation groove 12, and the limit block 10 moves out of the connecting groove 11. At this time, the second FRP bridge frame 2 can be extracted from the first FRP bridge frame 1 to achieve disassembly.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
