Description

Technical Field

[0001] The invention relates to the technical field of electric power engineering, and in particular to a transmission line tower base height adjustment device. Background Art

[0002] This is due to the concern about the stability of transmission line towers under different geological conditions. In the power transmission system, towers are key structures that support transmission lines, and their stability is directly related to the safe operation of the power system. In actual construction, tower foundations often face complex and changeable geological conditions, such as soft soil foundations, uneven settlement areas, and goaf areas, which pose severe challenges to the stability of towers.

[0003] Under complex geological conditions, settlement and deformation of the tower foundation are difficult to avoid, which may lead to tower tilt, line tension imbalance, and even serious consequences such as line breakage. In order to ensure the safe operation of transmission lines, effective measures must be taken to adjust the height of the tower foundation to adapt to changes in geological conditions.

[0004] Traditional tower foundation height adjustment methods, such as increasing foundation depth and adopting special foundation forms, can solve the stability problem to a certain extent, but they are often difficult to construct, costly, and have limited adjustment effects. Therefore, it is particularly important to develop a new type of transmission line tower foundation height adjustment device. Summary of the invention

[0037] In an optional implementation manner of the embodiment of the present invention, as Figure 5 As shown, the latch 8 is T-shaped.

[0038] Working principle: when in use, the present invention can quickly and conveniently install the pole tower 1. First, before installing the pole tower 1, the connecting plate 3 is fastened to the base 2 by bolts, and the connecting plate 3 and the lifting plate 4 can be matched. Then, the pole tower 1 is hung above by a crane and slowly lowered. The direction is manually adjusted from the bottom so that the connecting plate 3 falls into the groove of the lifting plate 4. The bottom of the connecting plate 3 presses the bottom of the buckle 5, so that the buckle 5 rotates inward by a certain angle. When the connecting plate 3 is completely placed in the groove of the lifting plate 4, the buckle 5 does not completely clamp the connecting plate 3. Then, the worm Ⅰ9 is manually rotated, thereby driving the worm wheel 10 to rotate, and then driving the disc 6 to rotate. The disc 6 drives the pin 8 to slide outward through the connecting rod Ⅰ7. The inclined surface of the pin 8 contacts the groove below the buckle 5, and the pin 8 is inserted into the groove below the buckle 5, thereby squeezing the buckle 5 to continue to rotate, so that the buckle 5 tightly clamps the connecting plate 3, thereby completing the installation and fixation of the pole tower 1.

[0039] After the installation is completed, if the angle of the pole tower 1 is tilted, the heights of the four corners of the pole tower 1 can be adjusted separately to straighten the pole tower 1. Specifically, the worm screw II 14 of the corner that needs to be adjusted is manually rotated to drive the support plate 12 to rotate, and the lower extrusion ring 13 squeezes the upper extrusion ring 11, thereby lifting the upper extrusion ring 11, thereby lifting the pole tower 1 at this corner, and adjusting the angle of the pole tower 1.

[0040] When the angle adjustment of the pole tower 1 is completed, the overall height of the pole tower 1 can also be adjusted so that the height reaches the expected value. Specifically, the threaded rod 23 is manually rotated to drive the horizontal slider II 22 to slide inward, and the horizontal slider II 22 drives the horizontal slider I 20 to slide to both sides through the connecting rod III 21. The horizontal slider I 20 drives the inclined slider 18 to slide outward through the connecting rod II 19. The inclined slider 18 squeezes the raised inclined surface under the support plate 12, so that the four corners are raised synchronously, so as to adjust the overall height of the pole tower 1, which is very convenient.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
