Self-climbing type installation system of steel cable tower

Abstract

The invention discloses a self-climbing type installation system of a steel cable tower. The self-climbing type installation system comprises a self-climbing assembly, a hoisting assembly attached tothe self-climbing assembly and a power assembly installed on the hoisting assembly. The self-climbing assembly comprises a rail attached to the surface of the steel cable tower and a climbing assemblysliding on the rail. The hoisting assembly comprises a climbing frame, a hoisting truss arranged at the top of the climbing frame and a moving trolley arranged on the top face of the hoisting truss and used for pulling a lifting appliance. The climbing frame is connected to the climbing assembly in a bolted mode. And the power assembly is arranged on the hoisting truss and used for executing hoisting and translation procedures. The self-climbing type mounting system is used for mounting the steel pylon, so that the butt joint precision of the steel pylon is controlled, the butt joint adjustability of the steel pylon is improved, the operation difficulty and complexity in the construction process are reduced, and the construction safety is also improved.

Description

technical field [0001] The application relates to the field of road and bridge construction, in particular to a self-climbing installation system for a steel cable tower. Background technique [0002] It is a very important job to control the line shape of the steel cable tower installation of a cable-stayed bridge or a suspension bridge. If the line shape deviation of the cable tower is large, it will not only affect the structural force of the cable tower, but also may affect the overall construction quality of the bridge. lead to engineering quality accidents. The current hoisting of steel cable towers mostly uses tower cranes. After the processed and formed steel tower segments are transported to the construction platform, they are hoisted in sections by large-tonnage tower cranes and formed by butt welding. Lift and attach to the wall. The main disadvantage of using a tower crane to hoist the cable tower is that it is difficult to control the line shape of the cable t...

The main disadvantage of using a tower crane to hoist the cable tower is that it is difficult to control the line shape of the cable tower

As the height of the cable tower increases, the tower crane and the cable tower must be attached to the wall for many times. Due to the uncertainty of the force of the tower crane on the wall and the influence of multiple wall-attached iterations, it is difficult to control the line shape of the cable tower.

[0003] In addition, other high-altitude operations during the installation of steel cable towers also need to rely on tower cranes or wall-attached elevators to transport construction personnel to high altitudes. The construction process is shortened and the construction cost is increased, which is not conducive to improving work efficiency
