Example (b):

according to the construction requirement, an operation starting area is selected on the bridge floor. According to the width of the bridge deck, marking the starting point of the construction operation of the bridge deck, selecting a plurality of modularized walking bedplate 1 and placing the walking bedplate on a flat ground or a floating platform below the bridge deck. The modularized walking platforms 1 are connected in a splicing mode through hole aligning bolts on the side connecting rods 3 to form an integral hanging basket platform for overhauling the bridge (as shown in figures 1 and 2). And a hook 5 (shown in figure 1) is arranged on the outer side of the walking platform 1 in the middle of the hanging basket platform through a bolt and is used for fixing a safety rope and tying the other end of the safety rope on a bridge deck railing or used for dragging and moving the hanging basket platform. The lower ends of the frame-shaped guardrails 2 are inserted into the sockets 4 arranged on the two outer sides of the walking platform 1 for the safety protection of the operating personnel on the hanging basket platform.

Inserting rods 15 are inserted into the side connecting rods 3 at the outermost sides of the walking platforms 1 at the two ends of the hanging basket platform and are fixed through bolts penetrating through the through holes (as shown in figure 3). The two ends of the inserted link 15 are respectively sleeved with a sleeve joint seat 6, a hanging lug above the sleeve joint seat 6 is connected with a third suspender 13 through a bolt, the third suspender 13 is connected with a second suspender 17 through an external thread adjusting rod 14, and the other end of the second suspender 17 is connected with one end of the first suspender 12 through a fork joint part 16 (as shown in fig. 2 and 4).

The fastening device 7 is provided with a groove 701, the bridge deck railings 02 on both sides of the operation area on the bridge deck are sleeved, and an end cover 702 (shown in fig. 7) is installed at the notch of the groove 701 through a bolt, so that the fastening device 7 is fixed on the bridge deck railings 02. On the deck, the upper side of the guide rail 8 is connected to the lifting lug 18 below one end of the anchor 7, so that the guide rail 8 is held fixed to the deck rail 02 by the anchor 7. If the rails 8 need to be extended, the joints between the rails 8 can be spliced to each other by the sleeve clamps 20 (as shown in fig. 4). The inside of the section of the guide rail 8 is of a C-shaped structure, the opening of the guide rail is downward, and two sides of the opening are bent inwards to form a slide rail. A rail trolley is arranged on a slide rail in the guide rail 8 in advance, the rail trolley can run in the slide rail through a rail wheel 10, and an adjustable lifting hook 9 is connected to a guide wheel seat 19 of the rail trolley (as shown in figures 5 and 6). One end of the adjustable lifting hook 9 is connected with the ear fork 11.

On the bridge floor, the assembled hanging basket platform on the flat ground or the floating platform is hoisted to the splicing height through a steel wire rope hoist or a crane. The lug at the top end of the first suspender 12 is connected with the lug fork 11 on the adjustable suspender 9 below the small rail car through a bolt. So that the basket platform remains fixed in the height direction and the basket platform is finally integrated with the rail trolley in the guide rail 8. After the connection is stable, the safety rope is tied on the bridge surface railing after the safety rope is threaded around the hook 5 at the middle walking platform 1 of the hanging basket platform. At this moment, the maintenance hanging basket platform is acted by the safety rope, can not move along the direction of the guide rail 8, and is kept fixed in the horizontal plane direction. And (4) removing the steel wire rope hoist or the crane, and enabling personnel to enter the maintenance platform from the bridge floor for operation. In the operation process, the horizontal posture condition of the hanging basket platform can be adjusted and overhauled by an operator through adjusting the external thread adjusting rod 14.

When the operation surface needs to be extended along the extending direction of the bridge according to the construction operation requirement, after an operator withdraws from the construction operation platform, the safety rope tied on the railing can be loosened on the bridge floor, and when the operator pulls the safety rope on the bridge floor to move along the extending direction of the bridge, the safety rope drives the first suspender 12 at the top of the operation platform and the adjustable lifting hook 9 at the bottom of the guide wheel seat of the guide rail trolley connected with the first suspender 12 through the hook 5, so as to drive the guide rail trolley to move along the guide rail 8. Finally, the operation hanging basket platform moves to a required construction position along the guide rail 8, and the safety rope is tied on the bridge deck railing to be fixed. Constructors can enter the operation hanging basket from the bridge floor to carry out the next operation.

After the construction operation is finished, the steel plate can be pushed backwards to be removed in the mode.
