Description

A hoisting structure for hoisting bridge tower crossbeam below decoration

Technical Field

The utility model relates to a lifting device specifically is a hoisting structure for hoisting bridge tower crossbeam below decoration.

Background

The bridge tower is an important part of a suspension bridge and a cable-stayed bridge, and a plurality of decorative components are added on the bridge tower, so that the aesthetic enjoyment can be added to a single bridge structure, and the bridge tower is an organic combination of structural engineering and building aesthetics. However, since the height of the pylons is generally high, this adds difficulty to the installation of the trim member. When the decoration component is installed, large-scale hoisting equipment is needed to hoist the decoration component to the high altitude, and then the operation personnel reinforce the decoration component, so that a large amount of equipment cost is increased. Especially, the installation of bridge tower crossbeam below decoration, current lifting device location is accurate inadequately to because the construction face is narrow, be unfavorable for the construction operation, the operation risk is big.

Disclosure of Invention

To the problem that exists among the above-mentioned prior art, the utility model provides a simple structure, with low costs, convenient operation, construction safety be used for hoist and mount bridge tower crossbeam below hoisting structure of decoration.

The utility model adopts the technical scheme as follows: a hoisting structure for hoisting a decoration part below a bridge tower beam comprises a hoisting frame, a first pulley lifting hook, a second pulley lifting hook, a fixed pulley, a winch and a steel wire rope, the first pulley lifting hook, the second pulley lifting hook, the fixed pulley, the winch and the steel wire rope are respectively provided with two groups, the hanger comprises an installation platform, a support frame for fixing the decorative piece is arranged on the mounting platform, a construction platform is arranged on the support frame, the two ends of the mounting platform are respectively connected with a lifting rope, the lifting rope is connected with a first pulley lifting hook, a supporting beam with two ends extending out of a cross beam is fixed on the bridge tower cross beam, the two ends of the supporting beam are respectively connected with the second pulley lifting hook, the fixed pulley is fixedly arranged on the bridge floor, the winch is arranged on the bridge floor, one end of the steel wire rope is wound on a winding drum of the winch in a rotating mode, and the other end of the steel wire rope is connected with the first pulley lifting hook after winding the fixed pulley and the second pulley lifting hook.

Further, the second pulley hook is a double-pulley-block hook.

Furthermore, a protective net is arranged on the construction platform in a surrounding mode.

The beneficial effects of the utility model reside in that:

(1) by adopting the hoisting structure of the utility model, large-scale hoisting equipment is not needed to enter the field, and only corresponding pulleys and I-shaped steel are needed, thereby saving a large amount of cost;

(2) the hoisting structure of the utility model can accurately position the decorative component, and is light and flexible;

(3) the utility model discloses a hoisting structure provides better construction platform for the construction operation personnel, and convenient operation reduces the operation risk, improves the operating efficiency.
