Description

Suspension type bridge overhauls platform

Technical Field

The utility model belongs to the technical field of bridge engineering, a maintenance construction of bridge is related to, concretely relates to suspension type bridge overhauls platform.

Background

Diseases often appear during bridge operation, and in order to guarantee operation safety, regular maintenance is needed. The conventional bridge maintenance method adopts a special maintenance vehicle, is very convenient and fast, is limited by the passing conditions under the bridge, and cannot be used for large-area repair operation under the bridge; the other method is to build a floor stand under a bridge as a platform, but the stand is built for a long time, and meanwhile, the stand foundation needs to be processed, so that the floor stand is difficult to build under the conditions of complex terrain and high river or bridge floor under the bridge.

Disclosure of Invention

The utility model aims at the above-mentioned problem, a suspension type bridge overhauls platform is provided, avoids receiving underbridge geological conditions or current condition restriction.

The technical scheme of the utility model as follows:

the utility model provides a suspension type bridge overhauls platform, the bridge both sides are equipped with anticollision barrier, its characterized in that respectively: a plurality of cross beams which are arranged at equal intervals in the transverse bridge direction are hung at a certain height below the bridge, two ends of each cross beam are respectively connected with a lifting rope, the upper ends of the lifting ropes are provided with hooks, and the two hooks are respectively hung on the anti-collision guardrails on two sides of the bridge; a plurality of distribution beams are arranged among the cross beams, and platform panels are laid on the distribution beams; guardrail vertical rods are further mounted at two ends of each cross beam respectively, and a guardrail cross rod is connected between the guardrail vertical rods on each side of the bridge.

The utility model has the advantages that:

(1) the platform is simple in structure, adopts a suspension type structure, and is not limited by the geological conditions and the passing conditions under the bridge;

(2) the cross beam adopts a triangular truss, so that the bearing capacity is strong, and the construction safety can be ensured;

(3) the platform can have enough to meet the need and recycle, has reduced cost input.

Drawings

FIG. 1 is a schematic view of a transverse bridge structure of the present invention;

fig. 2 is a schematic diagram of the forward bridge structure of the present invention.

Detailed Description

As shown in fig. 1 and 2, two sides of a bridge 1 are respectively provided with anti-collision guardrails 2, a plurality of cross beams 3 which are arranged at equal intervals in the axial direction of the bridge are hung at a certain height below the bridge, two ends of each cross beam are respectively connected with a lifting rope 4, the upper ends of the lifting ropes are provided with hooks 5, and the two hooks 5 are respectively hung on the anti-collision guardrails 2 at the two sides of the bridge; a plurality of distributing beams 6 are arranged among the cross beams, and platform panels 7 are laid on the distributing beams; guardrail vertical rods 8 are further mounted at two ends of each cross beam respectively, and a guardrail cross rod 9 is connected between the guardrail vertical rods on each side of the bridge.

The utility model discloses during the implementation, the crossbeam can adopt the triangle truss, can guarantee the bearing capacity of crossbeam. One plane of each triangular truss faces upwards, and the distribution beam can be made of scaffold steel pipes, is erected on the top surface of each triangular truss and is fixed with the upper chord of the truss through a fastener; the guardrail vertical rods and the cross rods can be made of small-diameter steel pipes, the guardrail vertical rods are fixed with the upper chord members of the truss through fasteners, and the guardrail cross rods are connected with the guardrail vertical rods through the fasteners; the platform panel can adopt bamboo plywood, has the characteristics of light dead weight and high strength, and is convenient to carry and install.

The utility model discloses during the implementation, according to the width of bridge, assemble into whole with the platform under the bridge earlier, then connect the lifting rope at crossbeam both ends, promote the platform to suitable height with the hoist engine on the bridge to hang the couple of lifting rope upper end on the anticollision barrier of bridge both sides.

Claims
