A kind of bridge hoisting equipment

Abstract

The invention discloses a bridge-hoisting device. The invention relates to the field of road and bridge construction machinery, including a removable rack, the low end of the track is provided with awalking wheel, the upper surface of that rack is provided with a working platform for conveying the bridge deck, a conveyor mechanism is diagonally arranged on the working platform, as one end of thatconvey mechanism is used as the load end of the bridge slab, the other end is provided with a tractor mounted on the working platform for pulling the bridge slab to move on the conveying mechanism, the working platform is provided with a lifting rack for lifting the bridge slab, two first lifts are installed on the lifting rack at the upper position of one end of the traction machine, a second lift is installed on the upper position of the other end, the front end of the bridge slab is lifted on the two first lifts, and the rear end is lifted on the second lifts, and is lifted and installed on the pier. To solve the problem of overturning and collision damage in the process of bridge deck hoisting, the bridge can be kept stable in the process of bridge hoisting without torsion, avoiding collision damage and protecting the integrity of the bridge.

Description

technical field [0001] The invention relates to the field of road and bridge construction machinery, in particular to bridge hoisting equipment. Background technique [0002] With the development of transportation, bridge erecting machinery and equipment have also been rapidly developed and applied, and the application of bridge erecting machines as indispensable equipment for erecting road bridges and railway bridges is becoming more and more extensive. The hoisting structure of the bridge erecting machine is an important part of the bridge erecting machine. It is responsible for the lifting of the bridge and is also the main load-bearing component of the bridge erecting machine. It plays a very important role in the lifting performance and work efficiency of the bridge erecting machine. The traditional bridge erecting machine has a lifting point at both ends of the hanging beam, and each lifting point is connected to a winch, and the hoisting machine drives the double lift...

AI Technical Summary

Problems solved by technology

The double lifting point lifting operation is unstable. During the lifting process, it is easy to cause a series of problems such as the torsion of the beam body in the air, difficulty in positioning, and large force on the lifting beam, which may easily lead to damage to the lifting beam, and there are certain safety risks.
