Problems solved by technology

When hoisting and positioning, wedge blocks in the same direction are used for positioning. Because there is a gap between the pin and the bolt hole, when the segments are placed, the wedge blocks will collide, causing displacement of the wedge blocks. The precise positioning cannot be done once, and a second precise positioning is required. Positioning; if the wedge block is installed one front and one reverse, the wedge block will be displaced in the opposite direction, making the segment unable to fall
Due to the large cross-section and heavy weight of the section of the tower, if wedge-shaped blocks are used for positioning, it is very difficult to perform secondary precise positioning, which is labor-intensive and time-consuming, and the positioning accuracy is not high

The device comprises a first segment, a second segment, a connection part and a positioning mechanism; the second segment is disposed over the first segment; the positioning mechanism is fixed at the upper end of the first segment; the lower end of the second segment is provided with positioning holes corresponding to the positioning mechanism; the first segment is inserted onto the positioning holes for positioning, through the positioning mechanism; the first segment is connected with the second segment through the connection part. The tower segment positioning device has the advantages that positioning precision is improved, and labor and time are saved.

Description

technical field [0001] The invention relates to the technical field of bridge technology, in particular to a steel tower segment positioning device and method. Background technique [0002] In the prior art, bolted steel towers are positioned using bolted holes, and wedge-shaped positioning blocks are fixed at the two-segment ports with pins and bolts. When hoisting and positioning, wedge blocks in the same direction are used for positioning. Because there is a gap between the pin and the bolt hole, when the segments are placed, the wedge blocks will collide, causing displacement of the wedge blocks. The precise positioning cannot be done once, and a second precise positioning is required. Positioning; if the wedge blocks are installed with one front and one reverse, the wedge blocks will be displaced in the opposite direction, making the segment unable to be positioned. Due to the large cross-section and heavy weight of the section of the tower, if wedge-shaped blocks are ...
