The hanging basket device can perform construction work at the whole undersurface of the bridge, thus, the construction bind zone is avoided, and the quality of bridge construction can be improved.

Description

The nacelle device of bridge construction

Technical field

The utility model relates to a kind of nacelle device that is used for the construction of bridge bottom surface.

Background technology

At present; The nacelle device that is used for bridge construction all is to be installed in the structural members such as truss on the bridge floor through cantilever, and it is positioned at the side of bridge, can only construct to the side of bridge and near very short one section bridge bottom surface of side; Can't carry out construction operation to whole bottom surfaces of bridge; For wide more bridge floor, there is bigger construction blind area in its bottom, is difficult to improve the quality of bridge construction.

The utility model content

The purpose of the utility model is the above-mentioned deficiency to prior art, and a kind of nacelle device of bridge construction is provided, and it can carry out construction operation to whole bottom surfaces of bridge, can improve the quality of bridge construction.

For achieving the above object; The nacelle device of the bridge construction of the utility model; The nowel beam that comprises bridge is characterized in that also comprising the suspension rod that is installed in several tie rod holes of nowel beam two ends, the suspension rod at two ends in twos one group link to each other through steel cable; Below all steel cables, be provided with a hanging basket, hanging basket movably is loaded on the steel cable through several structural members.

Said structure spare can be the suspension ring that are loaded on the roller on the steel cable, the support that is connected with roller, the hook that is connected with support and connect firmly with the framework of hanging basket, and suspension ring are hung on the corresponding hook.

Said structure spare also can for connecting rod on the framework that is fixedly arranged on hanging basket, with the collar that connecting rod connects firmly, cover is located on the steel cable.

During use, the operator spurs steel cable in hanging basket, can make hanging basket oppositely move, thereby construction operation is carried out in whole bottom surfaces of bridge, can improve the quality of bridge construction;

As the utility model further; On the nowel beam, also be provided with several lifting appliances; The drag hook that each lifting appliance comprises screw rod in the tie rod hole of being located between the suspension rod of two ends, connect firmly with the screw rod lower end, be loaded on nut and top board on the screw rod through screw thread, nut is positioned at the top board below and places on the nowel beam, on the nowel beam of nut both sides, also is respectively equipped with jack; The two ends of top board place on the jack, and drag hook hooks corresponding steel cable; Can increase the stability of shroud through lifting rope and weight, further improve protection effect; When steel cable occurs sagging or nowel beam when being arch, hanging basket moves to the stage casing of steel cable, and this moment, hanging basket was far away apart from the top of nowel beam; Can operate two jack and make the top board lifting; Descend spin nut to being adjacent to the nowel beam again,, draw steel cable on the drag hook the screw rod location; Can promote hanging basket, guarantee carrying out smoothly of operation;

In sum, the utility model can carry out construction operation to whole bottom surfaces of bridge, has avoided the construction blind area, can improve the quality of bridge construction.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Embodiment one

By Fig. 1 to shown in Figure 4, the nacelle device of this bridge construction, comprise bridge nowel beam 1, be installed on the suspension rod 2 in six tie rod holes in nowel beam two ends; The suspension rod 2 at two ends in twos one group link to each other with a steel cable 3 through securing member such as fastener, below all steel cables 3, be provided with a hanging basket 4, hanging basket 4 is provided with the railing of six framework 4a and connecting frame; The front and back end of each framework 4a all is fixedly connected with suspension ring 5; Two rollers 6 all are housed on the steel cable 3 above each framework 4a, and each roller 6 is connected with a support 7, is connected with hook 8 on each support 7; Suspension ring 5 are hung on the corresponding hook 8, make hanging basket 4 movably be loaded on the steel cable 3; On nowel beam 1, also be provided with six lifting appliances; The drag hook 10 that each lifting appliance comprises screw rod 9 in the tie rod hole of being located between the two ends suspension rod 2, connect firmly with screw rod 9 lower ends, be loaded on nut 11 and top board 12 on the screw rod 9 through screw thread; Nut 11 is positioned at top board 12 belows and places on the nowel beam 1; On the nowel beam 1 of nut 11 both sides, also be respectively equipped with jack 13, the two ends of top board 12 place on the jack 13, and drag hook 10 hooks corresponding steel cable 3;

The utility model utilizes tie rod hole intrinsic on the nowel beam 1 that steel cable 3 is installed, and movably is loaded on hanging basket 4 on the steel cable 3; During operation, the operator spurs steel cable 3 in hanging basket 4, can make hanging basket 4 oppositely move, thereby construction operation is carried out in whole bottom surfaces of bridge, can improve the quality of bridge construction; When steel cable 3 because of using for a long time or hanging basket is reppeared and now hung down and nowel beam 1 during as arch, hanging basket 4 moves to the stage casing of steel cable 3, hanging basket 4 is far away apart from the top of nowel beam 1 at this moment; Can operate two jack 13 and make top board 12 liftings; Descend spin nut 11 to being adjacent to nowel beam 1 again,, draw steel cable 3 on the drag hook 10 screw rod 9 location; Can promote hanging basket 4, guarantee carrying out smoothly of operation.

Embodiment two

Like Fig. 5 and shown in Figure 6, the difference of present embodiment and embodiment one only is that hanging basket 4 movably is loaded on the steel cable 3 through the collar 16 that is fixedly arranged on its framework 4a and goes up connecting rod 15, connect firmly and be placed on the steel cable 3 with connecting rod 15; During operation, the operator spurs steel cable 3 in hanging basket 4, can make hanging basket 4 oppositely move equally, thereby construction operation is carried out in whole bottom surfaces of bridge, can improve the quality of bridge construction; This structure is simple relatively, but frictional force is bigger, with embodiment one advantage is arranged respectively.

The utility model is not limited to above-mentioned embodiment, also can be varied like the connected mode of hanging basket and steel cable, but, all fall into the protection domain of this patent as long as adopt the described scheme of claim 1.
