when the pole tower sleeve joint 7 is installed, only the connecting rod 701 at one end of the pole tower pull rod 704 in the pole tower sleeve joint 7 needs to be inserted between two vertical ends of the U-shaped pendant 6 and fixed through the bolt, so that the operation is convenient and fast.

Example 5:

this embodiment provides a concrete structure of preventing wind with partial insulating cable for high voltage transmission system, as shown in fig. 9, including insulating part and installation department, wherein, the installation department is provided with two altogether, installs respectively at the both ends of insulating part, and two installation departments are fixed respectively on corresponding support on the high voltage transmission system shaft tower, make insulating cable between shaft tower and high voltage transmission line, are provided with the striking district in the insulating part, and the striking district is used for accepting high voltage transmission line's striking, separation shaft tower and high voltage transmission line's contact.

The insulating part comprises a first end insulator 2, a middle insulator 4 and a second end insulator 5, the mounting part comprises a hanging frame 1 and a tower sleeve 7, the middle insulators 4 are arranged in a plurality, the middle insulators 4 are connected in series end to end, one end of the first end insulator 2 is connected to the hanging frame 1, the other end of the first end insulator is connected to one end of the middle insulator 4 located at the most edge, one end of the second end insulator 5 is connected to one end of the middle insulator 4 located at the other most edge, and the tower sleeve 7 is connected to the other end of the second end insulator 5 through a U-shaped pendant 6;

the impact area adopts a combined impact piece 3, and the first end insulator 2 and the middle insulator 4 and the second end insulator 5 are detachably connected through the combined impact piece 3.

An inserting shaft 9 is arranged at one end of the first end insulator 2, two ends of the middle insulator 4 and one end of the second end insulator 5, and a locking hole 10 is formed in one end of the inserting shaft 9.

The combined impact piece 3 is provided with assembling insertion holes 302 at two ends, the insertion shaft 9 is inserted into the assembling insertion holes 302, the locking pin 304 is inserted above the combined impact piece 3, and the locking pin 304 is inserted into the locking hole 10 from top to bottom.

The pole tower sleeving piece 7 is of a strip frame structure, pole tower pull rods 704 are movably installed at two ends of the pole tower sleeving piece 7 in a penetrating mode, one ends, located inside the pole tower sleeving piece 7, of the pole tower pull rods 704 are provided with pole tower penetrating jacks 705, the other ends of the pole tower pull rods 704 are provided with connecting rods 701, and one ends of the connecting rods 701 are inserted between two vertical ends of the U-shaped hanging pieces 6 and fixed through bolts.

The tower pull rod 704 adopts a threaded structure, and the end of the tower pull rod 704, which is positioned outside the tower socket 7, is sleeved with the tensioning nut 703.

A limiting ring 702 is further arranged at one end, located outside the tower sleeve-connection piece 7, of the tower pull rod 704, the limiting ring 702 is of an arch structure, a connecting shaft 7021 is arranged between two ends of the limiting ring 702, and the connecting shaft 7021 penetrates through the tower pull rod 704.

By adopting the technical scheme:

when the tower socket piece 7 is installed, the tower socket piece 7 is firstly assembled, one end of a tower pull rod 704 is inserted into the tower socket piece 7, a tower through hole 705 on the tower pull rod 704 is sleeved on a support of a tower, then the tensioning nut 703 is rotated, the tower pull rod 704 moves outwards, the support can be locked, the operation is convenient and fast, the limiting ring 702 with the arch structure is further arranged at one end, located at the outer part of the tower socket piece 7, of the tower pull rod 704, the connecting shaft 7021 is arranged between the two ends of the limiting ring 702, the connecting shaft 7021 penetrates through the tower pull rod 704, and therefore the tensioning nut 703 is prevented from being excessively loosened, and the overall safety performance of the device is improved.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
