Example 1

[0022] As Figures 1 to 5 shown, the utility model provides a kind of steel structure anchor bolt fastening device of transformer substation, including sleeve 1, sleeve 1 lower end fixedly connected with sleeve cap 2, sleeve cap 2 is used to sleeve nut, magnet is arranged on the inner wall of sleeve cap 2 top, for adsorbing nut, sleeve cap 2 is set according to the structure of nut, sleeve 1 upper portion is provided with transverse force bar 3, sleeve 1 upper end is provided with positioning device;

[0023] The positioning device includes a sliding column 4, which is slidably connected to the upper end of the sleeve 1;

[0024] It also includes a limiting plate 41, which is used to fix it to the column of the steel structure. Multiple positioning columns 42 are fixedly connected to the bottom of the limiting plate 41. The upper end of the sliding column 4 is provided with a positioning hole 43, which is corresponding to the positioning column 42. The lower end of the positioning column 42 is tapered. The sliding column 4 slides upward and fits on the positioning column 42. The positioning column 42 is coaxially designed with the anchor bolt below to position the cap 2 and nut.

[0025] The limiting plate 41 is provided with a slot 44, and a locking bolt 45 is threadedly connected to one side of the slot 44. The limiting plate 41 is adapted to the structure of the steel column 30. Generally, the column is an H-beam with stiffening plates 40 inside. The slot 44 is inserted into it. If the H-beam column 30 does not have stiffening plates 40, then... Figure 4 The limiting plate 41 shown is inserted into the two sides of the H-beam column through the slots 44 on both sides and fixed by the locking bolts 45.

[0026] In Example 1, the limiting plate 41 is engaged with the steel structure column 30 through the slot 44, making the positioning column 42 coaxial with the anchor bolt of the pre-embedded steel plate at the bottom of the installation pit 20. The sliding column 4 extends and retracts relative to the sleeve 1. After the positioning hole 43 of the sliding column 4 is inserted with the positioning column 42, the sleeve 1 and the cap 2 are coaxial with the anchor bolt. The sleeve 1 falls vertically, and the cap 2, with the nut, aligns with the anchor bolt. Then, by turning the lever 3, the anchor bolt is securely installed. In this process, the tightening of the anchor bolt has good guidance, which facilitates the construction operation. Example 2
