Description

Technical Field

[0001] The utility model relates to a connecting piece, in particular to a connecting piece for a cross beam of a steel tower, belonging to the technical field of cross beam connection of steel towers. Background Art

[0002] The iron frame for erecting high-voltage transmission lines is also called a steel tower. High-voltage power transmission is a way of transmitting power after boosting the voltage output by a generator through a transformer in a power plant. The reason for adopting this way of power transmission is that under the same transmission power, the higher the voltage, the smaller the current. In this way, high-voltage power transmission can reduce the current during power transmission, thereby reducing the heat loss generated by the current and reducing the material cost of long-distance power transmission.

[0003] During the erection of the steel tower, in order to ensure the structural strength, cross beams are usually erected between the cross frames. In the existing process of erecting cross beams, the cross beams are directly welded or fixed to the cross frames by bolts. It is not convenient to remove and replace the cross beams after they are bent or damaged. When the cross beams are fixed by bolts, since the cross beams are exposed, the joints are likely to become loose or deformed when they are shaken under stress.

[0004] To solve the above technical problems, a connecting piece for a cross beam of a steel tower is proposed. Content of the Utility Model

The slide bars are slidably connected with the connecting frame through the sliding grooves. A fourth bolt is threadedly connected to one side of the limiting frame. One end of the fourth bolt is threadedly connected to the connecting frame.

[0009] Further preferably, a first bolt is threadedly connected to one side of the connecting frame. One end of the first bolt is threadedly connected to the cross frame.

[0026] As Figures 1-4 shown, the embodiment of the present utility model provides a tower cross beam connector, which is composed of a cross frame 1, a cross beam 2, a main body mechanism 10 and a limiting mechanism 20.

[0027] The main body mechanism 10 includes a connecting frame 11 and a fixing frame 14. A connecting groove 32 is integrally formed on one side of the connecting frame 11. The connecting frame 11 is connected to the cross frame 1 through the connecting groove 32. The connecting frame 11 is engaged with the cross frame 1 through the connecting groove 32. A placement groove 12 is integrally formed on one side of the connecting frame 11. The cross beam 2 is supported by the placement groove 12. One side of the cross beam 2 is engaged with the placement groove 12. And the fixing frame 14 is sleeved on one side of the cross beam 2.

The convex parts 31 of the fixing frame 14 are engaged with the connecting frame 11 through the limiting grooves 18 to fix the cross beam 2 and the connecting frame 11 and prevent the cross beam 2 from disengaging from the connecting frame 11. Empty grooves 17 are equidistantly distributed on one side of the connecting frame 11. The empty grooves 17 are provided to allow local deformation of the connecting frame 11 when the cross beam 2 is overloaded, preventing the cross beam 2 from breaking. Sliding grooves 25 are formed on both sides of the connecting frame 11.

[0028] In one embodiment, in order to facilitate the fixation of the connecting frame 11 and the cross frame 1, a first bolt 13 is threadedly connected to one side of the connecting frame 11, and one end of the first bolt 13 is threadedly connected to the cross frame 1.
