Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of leveling, in particular to a wedge-shaped block locking leveling device for the flatness of the end surface of a steel tower segment. Background Art
[0002] With the rapid development of infrastructure construction at home and abroad, bridges, as important infrastructure for transportation development, have a variety of erection methods and more advanced steel structures. With the continuous maturity of bridge design and production technology, bridge steel structures are becoming increasingly high-end and complex. At present, there is a lack of accurate and simple methods to control the flatness of the end faces of steel tower segments. The old devices for controlling the flatness of the end faces of steel tower segments are not easy to operate and have low precision, waste materials, and are not adjusted properly, so that the functions of the current equipment cannot meet the requirements of high efficiency and high quality, affecting the sustainability of manufacturing. In the manufacturing process of bridge steel structures, the plane and end face processing of steel structures and the flat and vertical splicing processes are complex, time-consuming, and require high precision. The leveling of steel structures has a great impact on subsequent manufacturing processes.
[0003] The original steel tower segment end face flatness adjustment had no fixed equipment. Most of them were cut on site using steel plates, and the steel plates and remaining mechanical parts were welded to ensure relative fixity. Manually cut wedge blocks were placed at the bottom of the steel tower for a week. When adjusting, the wedge blocks were hammered to raise the part. However, manual hammering had almost no accuracy, and the magnitude of the applied force could not be accurately controlled, which often led to mistakes and readjustments, greatly wasting construction time. Moreover, this method was used for the current situation. Most of the manually cut materials could not achieve the required accuracy, and they were used by welding, which was disposable, wasting recyclable materials and increasing manufacturing costs. The materials required for on-site cutting by workers may be irregular, and the bridge steel structure is heavy. If the materials burst out, it will be a great safety hazard to personnel.
