Problems solved by technology

If the inclination angle of the iron tower is too large, the iron tower has to be replaced, and the replacement of the iron tower requires a large amount of work, and most of the iron towers are distributed in the fields in mountainous areas, which not only makes the construction difficult, but also easily affects the production and life of local residents
The existing tower foundation anchor bolts have a certain reserved length, but they can only cope with extremely small settlements. Some iron tower foundations are installed with oil cylinders in advance, and the oil cylinders are used to lift when the tower foundations settle, but the installation of oil cylinders The cost is high, and it is prone to damage and leakage when it is outdoors for a long time, and the stability cannot be guaranteed
When the iron tower is connected, due to the large number of connecting parts required, the operation is often hindered due to space limitations during fastening and adjustment

Embodiment Construction

[0014] Such as Figures 1 to 3 As shown, a power transmission tower tilt correction bolt is an integrated structure of an upper bolt part 41 and a lower nut part 42, and a connecting head 43 is arranged on the top of the upper bolt part 41. The shape of the connecting head 43 can be a straight protrusion in the figure, or It is cross-shaped, square, etc., and can also be a groove, and its function is to connect with torsion tools such as wrench and screwdriver. When the bolts are in use, the lower nut part 42 is connected to the anchor bolt of the iron tower, and the upper bolt part 41 is connected to the anchor of the iron tower, so as to play the role of continuous deviation correction.

[0015] Such as Figure 4 , 5 As shown, a deflection correction device for iron tower connection includes an upper flange plate 1, a lower flange plate 2, a deflection correction bolt 4, a lower fixing nut 6, an upper leveling nut 7, an upper fixing nut 8, a reinforcing screw 9, and a rein...

Abstract

The invention discloses a steel pylon inclination correction bolt which comprises an upper bolt portion and a lower nut portion. The upper bolt portion and the lower nut portion are of an integrated structure, and the top of the upper bolt portion is provided with a connector. The inclination correction bolt is in the integrated design, accordingly, connection strength can be improved, space limitation does not need to be considered in the installation process, and installation quality of the connection rectifying device is further improved.

Description

technical field [0001] The invention relates to a maintenance tool for a power transmission tower, in particular to a power transmission tower tilt deviation correction bolt and a connected deviation correction device for the power transmission tower. Background technique [0002] Iron towers are widely used in power transmission, communication and other fields. During the use of iron towers, tower base settlement often occurs, especially in goaf areas, where settlement is particularly obvious. If the inclination angle of the iron tower is too large, the iron tower has to be replaced, and the replacement of the iron tower requires a large amount of work, and most of the iron towers are distributed in the fields in mountainous areas, which not only makes construction difficult, but also easily affects the production and life of local residents. The existing tower foundation anchor bolts have a certain reserved length, but they can only cope with extremely small settlements. S...
