Curbs are fixedly installed on the left and right sides of the top of the box girder plate 1 , and a locking sliding frame 2 is clamped on the curb. At this time, the locking sliding frame 2 is stuck on three sides above and on both sides of the road edge.

A traveling fixing block 9 is fixedly installed on the side of the locking carriage 2 , and a traveling motor 10 is fixedly mounted on the outer surface of the traveling fixing block 9 , and a driving gear 15 is fixed on the output shaft of the traveling motor 10 , and the side of the locking carriage 2 is fixedly installed There is a traveling fixed plate 11 located above the driving gear 15, and the traveling fixed plate 11 is fixed with a fixed shaft 12. The external movable sleeve of the fixed shaft 12 is connected with a traveling wheel 13 located under the traveling fixed plate 11, and the traveling wheel 13 is connected to the box beam. The road of the flat plate 1 is in contact with the side wall, and a traveling gear 14 is fixed coaxially and fixedly installed on the bottom. Wherein, the upper and lower ends of the traveling gear 14 are fixedly installed with the traveling wheel 13, and the diameter of the traveling gear 14 is smaller than the diameter of the traveling wheel 13. The outer edge of the traveling gear 14 meshes with the driving gear 15, and the traveling fixing plate 11 is located at The traveling wheels 13 are arranged symmetrically on the upper and lower sides.

The traveling motor 10 drives the driving gear 15 to rotate, thereby driving the traveling gear 14 to rotate, and then drives the traveling wheel 13 to travel along the side of the road. The locking sliding frame 2 is driven to move as a whole, and the movable device is realized. Compared with the previous fixed metal railings, the work efficiency is improved, and the operation is simpler. The inner side of the top of the locking sliding frame 2 is fixedly installed with two support frames 17, and The two supporting frames 17 are movably sleeved with driven rollers 18 through fixed pins. The number of the driven rollers 18 is six, and the six driven rollers 18 are evenly distributed on the inner side of the top of the locking carriage 2 . The inner side of the locking sliding frame 2 away from the fixing block 9 (the inside of the bridge in FIG. 2 ) and the inner side extending to the bottom of the box girder plate 1 (see the surface of the bridge in FIG. 3 ) are movably sleeved with driven rollers 18 through the support frame 17 , and The outer circle of the moving roller 18 fits with the curb.

When in use, the safety protection device for high-altitude construction of the bridge checks whether each structure is in good condition. After correct, the traveling motor 10 is started, and the traveling motor 10 drives the driving gear 15 to rotate, thereby driving the traveling gear 14 to rotate, and then driving the traveling wheel 13 along the road. Traveling along the side, at this time, the driven roller 18 inside the locking slide 2 and the box girder plate 1 rotates, driving the locking slide 2 to move as a whole, when it moves to the construction position, turn off the motor, and the metal The protective fence effectively avoids the occurrence of personal injury and material damage from high-altitude falls, and ensures the safety of workers. At the same time, the waterproof sunshade cloth on the top of the fixing frame 16 effectively reduces the impact of sun and rain, and further ensures the safety of workers. When the bridge deck needs to work on large-scale equipment, the turning gear 5 is driven to rotate by the turning motor 4, thereby driving the turning shaft 8 to rotate through the driven wheel 7, and then the L-shaped fixing frames 16 on both sides are opened to the outside to provide work for large-scale equipment. In addition, when the L-shaped fixing frame 16 is opened outward, the metal protective fence is in a horizontal state to prevent the occurrence of falling accidents, and the waterproof sunshade cloth is in a vertical state to further protect the staff. The turning gear 5 is driven by the turning motor 4 to rotate, and then the turning shaft 8 is driven by the driven wheel 7 to rotate, so that the fixing frame 16 can be returned to the initial state.
