This invention provides a communication landscape tower that is easy to maintain, relating to the field of communication landscape towers. It includes a supporting low pole, a supporting ball, an annular retaining plate, and a mobile ladder. The supporting low pole is fixedly vertically installed, and a flange connector is installed at the top of the supporting low pole. The supporting ball is fixedly installed at the top of the flange connector. This invention moves the mobile ladders on each side outwards by different lengths, creating a stepped effect that facilitates subsequent climbing by maintenance personnel and improves their work efficiency. The invention also features a fixed protective vertical plate that assists maintenance personnel in climbing and provides some protection. Finally, the invention uses three annular retaining plates that flip to the same height and merge together to assist maintenance personnel in climbing and to facilitate their standing.

This utility model discloses a busbar connector box maintenance lifting platform, which includes a two-wheeled frame with a front fork, a rear fork, and a handlebar; a front wheel mounted on the front fork; a rear wheel mounted on the rear fork; a height-adjustable seat mounted on the top side of the middle of the frame; and two L-shaped support frames respectively hinged to the front and rear forks. Each support frame includes a U-shaped, open pressure beam that extends beyond the wheel opening; and a support rod with one end fixedly connected to the end of the pressure beam and the other end hinged to the front or rear fork of the frame. The frame, with the front wheel mounted on the front fork and the rear wheel on the rear fork, can be moved flexibly and quickly into narrow passages. The seat can be raised to a certain height for maintenance of the busbar connector box at higher positions. The support frames support the top of the frame, and the U-shaped pressure beam provides a large span of support, thus providing sufficiently stable support after raising the frame, facilitating operation while standing on the platform.

This invention discloses scaffolding for arch ribs of arch bridges, relating to the field of scaffolding technology. The invention includes four scaffolding poles and two frame plates. Two limiting holes are provided at one end of each scaffolding pole. Two connecting sleeves are provided on the lower surface of each frame plate. One end of each scaffolding pole is in movable contact with the inner wall of the connecting sleeve. U-shaped sleeves are provided on both sides of each frame plate. The surface of the connecting sleeves is provided with a disassembly and assembly mechanism for assembling and disassembling the scaffolding poles. A fixing mechanism is provided inside the U-shaped sleeve. By rotating a lead screw, the lead screw drives a second slider to move horizontally along the inner wall of a second sliding groove. The second slider moves the scaffolding poles horizontally through the connecting sleeves, thus facilitating the horizontal displacement of the scaffolding. This allows construction workers to stand on the scaffolding and perform construction work at different locations on the two arch ribs of the arch bridge. Simultaneously, it effectively reduces the amount of scaffolding used during construction and effectively reduces the time required to erect the scaffolding.
