Described location-plate is provided with locating hole, and is connected through the described flange of this locating hole with single hop tower cylinder two ends by connecting bolt I.
Described reserved line locating notch I is described erection column screwed hole theoretical pitch with the spacing of described reserved line locating notch II.
Described reserved line locating notch III is located at the center of two described erection column spacing.
Described erection column is connected with described welding positioning tool by connecting bolt II.
The utility model compared with prior art has the following advantages:
1, owing to being provided with the location-plate be connected respectively with single hop tower cylinder two ends flange in the utility model, and the side of location-plate is provided with reserved line locating notch I, its opposite side is provided with reserved line locating notch II, reserved line locating notch III is provided with in the middle part of it, therefore, by connecting reserved line locating notch I and reserved locating notch II and the reserved locating notch III of ruling of ruling, mark erection column two screwed hole center line and two erection column center lines, and determine that these three lines are scribe fiducials, two ends screwed hole center line chalk line is connected simultaneously, be convenient to correct erection column integrated straight dimension, thus make Adjustment precision high, affect by operating personnel's collimation error when avoiding artificial line, and welding and cooling time the factor such as the thermal stress distortion that causes impact, make linearity in tower cylinder good with overall package in each section of tower cylinder, all meet the installation requirement of conductor rail.
2, the utility model structure is simple, simple for production, uses material light, is easy to dismounting, can repeatedly utilizes, and can realize the line of conductor rail batch high accuracy.
