Description

Technical Field

[0001] This utility model relates to the field of crossing tower technology, and in particular to an irregularly shaped adjustable crossing tower. Background Technology

[0002] In the field of power engineering, transmission lines often need to cross various obstacles such as rivers, valleys, railways, and highways. Traditional crossing towers suffer from inflexible height and tension adjustments when facing complex terrain and crossing requirements of varying heights and widths. This makes it difficult to accurately adapt to different crossing scenarios, which may increase construction difficulty, reduce efficiency, and even affect the safe and stable operation of transmission lines.

[0003] Traditional crossing towers have relatively fixed structures and limited height adjustment methods. Adjustments are typically made through cumbersome methods such as replacing sections of the tower, which is time-consuming, labor-intensive, and costly. Furthermore, there is a lack of precise and convenient adjustment devices for conductor tension during crossing, making it difficult to adjust tension in real time according to actual operating conditions. This can lead to conductor damage due to excessive tension or swaying and loosening due to insufficient tension, affecting power transmission safety. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the structure of the crossing tower is relatively fixed, the means of height adjustment are limited, and adjustments can usually only be made by replacing some tower sections, which is time-consuming, labor-intensive and costly. Therefore, this invention proposes a non-standard adjustable crossing tower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable cross-tower with an irregular shape, comprising vertical columns, three first horizontal columns fixedly connected between each vertical column, a first X-shaped rod fixedly connected between each first horizontal column, triangular plates fixedly connected to the surface of each vertical column and between each first horizontal column, a lifting column penetrating and slidably connected to the center of the two uppermost triangular plates, a hydraulic cylinder embedded in the bottom of each lifting column, the bottom of each hydraulic cylinder fixedly connected to the triangular plate, a lifting frame fixedly connected to the top of each lifting column, trapezoidal plates and fixed plates fixedly connected inside the lifting frame and near both ends, a screw provided between each trapezoidal plate and fixed plate, a lifting plate threadedly connected to the surface of each screw, vertical rods fixedly connected to the bottom of each lifting plate and near its four corners, a U-shaped plate fixedly connected to the bottom of each vertical rod, and rotating rollers fixedly connected to the inside of each U-shaped plate and near both ends.

[0031] Working principle: Start the hydraulic cylinder 11. Its extension and retraction movement causes the lifting column 10 to slide vertically under the limit of the triangular plate 9. When the lifting column 10 moves up and down, it drives the top lifting frame 13 to rise and fall together, realizing the adjustment of the entire tower height. The limit ring 12 restricts the movement range of the lifting column 10 to prevent excessive movement. Start the motor 19. Its output end drives the screw 16 to rotate. Because the screw 16 is threadedly connected to the lifting plate 18 and the lifting plate 18 can only move vertically under the restriction of the limit rod 17, the rotation of the screw 16 causes the lifting plate 18 to move up and down along the screw 16. When the lifting plate 18 moves, it drives the bottom vertical rod 20 and U-shaped plate. 21. Lifting and lowering: The rotating roller 24 inside the U-shaped plate 21 is used to support the conductor. The tension of the conductor is adjusted by changing the height of the rotating roller 24. At the same time, the tension detector 23 inside the U-shaped plate 22 detects the conductor tension in real time and feeds back the data for precise adjustment. Throughout the process, the vertical column 1, the inclined column 2, and the base plate 3 form the bottom support structure to ensure the stability of the tower. The first horizontal column 4, the first X-shaped rod 5, and the triangular plate 9 enhance the connection stability between the vertical columns 1. The second horizontal column 6, the second X-shaped rod 7, and the inclined rod 8 further reinforce the structure between the inclined columns 2, so that the crossing tower remains stable when subjected to conductor tension and external wind loads, ensuring the safe crossing of the transmission line.

[0032] The wiring diagrams of the hydraulic cylinder 11, motor 19, and tension detector 23 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the hydraulic cylinder 11, motor 19, and tension detector 23 will not be explained in detail.
