[0018] The specific embodiment is as follows in combination with the drawings.

[0019] Embodiment

[0020] As Figures 1-5As shown, in the embodiment, a cable tower disassembly and assembly horizontal connection operation platform is mainly disclosed, which comprises a frame 1, the frame 1 comprises vertical rods 11 arranged at four corners, the adjacent vertical rods 11 are connected through horizontal rods 12, the top and bottom of the frame 1 are provided with steel plate nets 13, the top end of one side vertical rod 11 is provided with a hook 14 for hanging on the horizontal connection, the adjacent frames 1 are connected through a clamping block 2, a reinforcing plate 3 is bolted to the adjacent vertical rods 11 of the adjacent frames 1 to realize the connection, the reinforcing plate 3 is arranged along the length direction of the frame 1, and the length of the reinforcing plate 3 is the same as the length of the frame 1. Specifically, the frame 1 is welded through the vertical rods 11, the horizontal rods 12 and the steel plate nets 13, and the whole is a rectangular cuboid channel structure, the steel plate net 13 at the bottom provides support for the construction personnel and is convenient for the construction personnel to pass by, and the steel plate net 13 at the top can play a shielding role. The frame 1 is hung on the horizontal rod 12 of the horizontal connection through the hook 14, and one side vertical rod 11 directly abuts against the outer edge of the horizontal connection, so that the stable connection of the operation platform and the horizontal connection is realized. In addition, the operation platform is modularly arranged, the number of frames 1 required can be increased or decreased according to the distance between the cable tower columns (i.e. the length of the horizontal connection), the operation platform is convenient for repeated use, and the flexibility of the device is improved. The clamping block 2 is in the shape of a U, when the frames 1 are assembled, the corresponding faces of the adjacent frames 1 along the width and height directions are overlapped, the adjacent vertical rods 11 of the adjacent frames 1 are clamped together through the clamping block 2, and the reinforcing plate 3 is fastened and connected through bolts, so that the two adjacent vertical rods 11 are limited in the space enclosed by the clamping block 2 and the reinforcing plate 3, the splicing of the adjacent frames 1 is realized, and the reinforcing plate 3 abuts against all the vertical rods 11 on one side, so that certain bending and shearing resistance is provided. It should be noted that, due to the large self-weight of the horizontal connection and the lifting weight limit of the tower crane, when disassembling, the horizontal connection needs to be removed in part, then the whole horizontal connection is lifted, and then is transported to the disassembly site for the second disassembly; when installing, the whole horizontal connection is lifted without complete assembly, the horizontal connection is connected with the column, and then is further assembled. Therefore, the operation platform can be used as a passage for construction personnel and as an operation platform during disassembly and assembly of the horizontal connection.

[0024] Preferably, the plugboards 5 are respectively clamped with the clamps 4 on the upper side and the lower side. Specifically, the plugboards 5 are simultaneously subjected to the limiting action of the two clamps 4 on the same placement position along the length direction, and the stability of the installation of the plugboards 5 is ensured. In the use process of the platform, the existence of the clamps 4 can prevent the plugboards 5 from loosening due to external force or vibration, and the safety is ensured.
