Description
Technical Field
The utility model relates to the technical field of steel structure platform installation equipment, in particular to a steel structure platform butt joint adjusting device.
Background
In the installation process of large and ultra-large steel structural members such as steel structure bridges and ship lifts, the steel structure bridge or ship lift has the characteristics of large size, heavy weight and the like, in order to reduce the cost of hoisting equipment, the common practice is to divide the steel structure into a plurality of sections of steel structures, and the connection and the fixation of adjacent steel structures are realized through bolts or welding modes, so that the integral functions of the steel structure bridges or the ship lifts are realized. In the construction and implementation process, the connection of the joints of the structural members is a crucial step, and the connection effect directly determines the flatness and the structural strength of the formed steel structure platform.
According to the conventional construction method, since a single-section steel structure weighs several hundred tons or even thousands of tons, the hoisting is often completed by a floating crane or a large cable machine. Misalignment in the elevation direction or the running water direction often occurs at the joint due to factors such as uneven center of gravity adjustment, manufacturing dimensional deviation, improper choice of the hanging point, thermal deformation, and the like. How to construct, the elevation of the joint of the adjacent connecting steel structures is flush, and the centering is left and right, which is a control key point and a difficult point in the construction process.
Conventionally, in the manufacturing process of manufacturers, a plurality of positioning pins are matched and drilled in advance, so that the alignment of centers and the consistency of heights of joints of two sections of platforms are ensured. The method can be realized theoretically, but in the actual construction process, the lifting points are uneven, the center of gravity is not in the centroid, or the platform is deformed due to thermal expansion and contraction, so that the holes are misplaced, and the positioning pins are tapered pins, but the size is too small relative to the platform, so that the stress of the platform is not overcome, and the misplaced parts are corrected. If the size of the locating pin is increased, stress concentration is caused, and the locating hole of the connecting plate is damaged first. Or the pin penetrating work can not be realized by manpower because the pin penetrating force is too great in mid-air.
Or constructing by using a soil method, welding a plurality of L-shaped steel blocks on the top and the side surfaces of the platform with smaller relative sizes, driving gaps at the lower parts of the steel blocks into the other platform by using steel wedges, and pressing the platform with more elevation to enable the platforms to be level. The method can realize adjustment in multiple directions, but the platform has larger structural rigidity, can adapt to a small structure, and is always torn at the welding seam of the L-shaped steel block for a large steel structure, the downward pressure is insufficient to adjust the platform in place, and the adjustment direction is unidirectional adjustment.
Or fixing a lifting bracket on the generated structural surface for adjusting the size. When in hoisting, the hoisting steel wire rope or the length change of the hydraulic oil cylinder on the hoisting support is utilized to adjust the elevation. In the method, adjustment can be realized in the elevation direction, but along the water flow direction, the hoisting support is fixed on the platform and cannot move, so that the adjustment in the horizontal direction is difficult to realize. The method can not realize millimeter-level adjustment due to poor adjustment precision of the hoisting steel wire rope or the hydraulic cylinder.
Aiming at the defects in the traditional construction method, the utility model provides a steel structure platform butt joint adjusting device which can simultaneously realize the adjustment of the height and the flow direction size and the millimeter level adjustment.
