Wedge type large-diameter round pipe column lifting and overturning device

Abstract

The invention relates to a wedge type large-diameter round pipe column lifting and overturning device. The wedge type large-diameter round pipe column lifting and overturning device comprises a horizontal bearing steel plate, and an inclined support bracket is arranged on the upper surface of the bearing steel plate. The lower end of the support bracket is fixedly connected with the bearing steelplate, and a supporting seat is fixedly connected between the support bracket and the bearing steel plate. A support rod perpendicular to the bearing steel plate is arranged on the upper surface of the support bracket, and the upper end of the support rod is covered with a rubber ball. A support pad assembly for underlaying a round pipe column is disposed on the outer side of the lower end of thesupport bracket, and a supporting block for supporting the round pipe column in the round pipe column overturning process is disposed at the lower end of the support bracket. The supporting block is located on the bearing steel plate, and the rubber ball and the supporting block are arranged on the axis of the support bracket. The length of a connecting line of a point through which the supportingblock is in contact with the lower end of the round pipe column and the center of the rubber ball is not less than the difference between the diameter of the round pipe column and the radius of the rubber ball. The wedge type large-diameter round pipe column lifting and overturning device is simple in operation, simple in structure and high in safety and stability.

Description

technical field [0001] The invention relates to the technical field of a lifting device, in particular to a lifting and turning device for a wedge-shaped large-diameter circular pipe column. Background technique [0002] In the process of building construction, cylindrical steel pipes with large weight and size are used. The design of giant columns poses great challenges and higher requirements for the production, transportation and installation of steel structures. [0003] For the construction of super high-rise buildings, on-site steel structure installation is the focus and difficulty of the entire project construction. The difference in installation schemes will directly affect the overall construction progress, project quality, economic benefits, and the quality of the installation scheme, especially on key routes. The application of construction techniques and innovative points has a direct impact on construction efficiency, so it is very important to determine advanc...

Problems solved by technology

[0005] At present, it is more common to use a tower crane to turn over a steel column or use a car crane to place the steel column on a sleeper to turn over the steel column, and directly use a tower crane to turn over the steel column. When the lifting point exceeds the overall center of gravity of the steel column during the hoisting process, the steel column will be turned over. The column will fall in the direction of turning over. Due to the self-heaviness of the steel column, the arm of the tower crane is susceptible to a large instantaneous impulse, which will cause damage to the tower crane and cause danger. A slight impact may break the sling, causing the giant column to roll over and round. During the turning process of the pipe column, the rotation and offset may be caused by factors such as the asymmetry of the lifting point. Although the safety performance of the column is greatly improved, multiple truck cranes are required for lifting operations. Steel columns will enter the site during the entire construction process, requiring a truck crane to be stationed for a long time for irregular hoisting, which not only increases the working time, but also reduces the cost of the tower crane. Use efficiency, and increase the cost of construction machinery, reduce the overall construction progress
