The following detailed description of the present invention is provided to facilitate the understanding and appreciation of the technical aspects of the present invention in connection with the accompanying drawings.

Example (b):

a10 KV hoisting type common-tower double-circuit insulated folding cross arm is shown in a figure 1 and a figure 2 and comprises a lower folding joint 11, an upper folding joint 12, a vertical rod 3, an upper left cross arm 41, a lower left cross arm 42, an upper right cross arm 43, a lower right cross arm 44, a wire support 5, a left auxiliary suspension rod 61 and a right auxiliary suspension rod 62. The structure that lower folding joint 11 and last folding joint 12 are similar, and the size is different, and in this scheme, last folding joint 12 is "T" shape structure, and the centre supplies montant 3 to cut into to fixed through bolt and montant 3, the cross section of montant 3 is circular, is circular hollow tube. The center of the lower folding joint 11 is fixedly connected with the lower end of the vertical rod 3. The vertical rod 3 is provided with a row of equidistant fixing holes 31. The upper folding joint 12 is sleeved on the vertical rod 3 and fixedly assembled with the corresponding fixing hole 31. Thus, the distance between the upper folding joint 12 and the lower folding joint 11 can be adjusted according to the position of the selected fixing hole 31.

Two ends of the upper folding joint 12 are respectively connected with an upper left cross arm 41 and an upper right cross arm 43 through folding structures, and two ends of the lower folding joint 11 are respectively connected with a lower left cross arm 42 and a lower right cross arm 44 through folding structures. As shown in fig. 4 and 5, the folding structure includes two mounting holes 22 and a fixing bolt 21 inserted into the mounting hole 22. The upper folding joint 12 has slots at both ends, which can be fitted with the ends of the cross arm, and then the folding joint and the cross arm are fixed by two fixing bolts 21, and when folding is required, one fixing bolt 21 can be removed, while the other fixing bolt 21 rotates as a rotating shaft, thereby realizing folding as shown in fig. 2.

Meanwhile, as can be seen in fig. 7, the cross section of the upper left cross arm 41, the lower left cross arm 42, the upper right cross arm 43 and the lower right cross arm 44 is a long waist type structure. It can be seen from this structure that when the wire holder 5 and the member fixed to the cross arm are assembled, the rotation in the circumferential direction is not easily caused, the assembly is firm and the reliability is greatly improved.

In addition to the above configuration, in order to further improve the structural reliability, as shown in fig. 1 and 3, the upper left cross arm 41 and the lower left cross arm 42 are supported and connected by a left auxiliary boom 61, and the upper right cross arm 43 and the lower right cross arm 44 are supported and connected by a right auxiliary boom 62.

For the auxiliary suspension rods, the left auxiliary suspension rod 61 and the right auxiliary suspension rod 62 both comprise a female rod 71 and a male rod 72, the female rod 71 is sleeved on the male rod 72 and is adjusted in length in a telescopic mode, a locking bolt 73 is arranged at the end portion of the female rod 71, and the locking bolt 73 is used for adjusting the fixed position of the male rod 72 in a loosening mode. During operation, the locking bolt 73 can be loosened, so that the female rod 71 and the sub-rod 72 can be telescopically adjusted in length, and then the locking bolt 73 is fastened, so that the female rod 71 and the sub-rod 72 are fixed, and a cross arm is supported.

The upper ends of both the left auxiliary boom 61 and the right auxiliary boom 62 are provided with a hanging ring 74. Therefore, the structure can be hoisted through the crane, and the operation burden of engineering personnel is reduced.

A plurality of wire holders 5 are also fixed to the upper left cross arm 41, the lower left cross arm 42, the upper right cross arm 43, and the lower right cross arm 44 in a sleeved manner. Referring to fig. 1 and 6, fig. 1 shows one configuration of the wire holder 5.

Specifically, on the basis of fig. 1, a preferred structure as shown in fig. 6 can be designed, specifically as follows: the wire support 5 comprises a clamp seat 51, a cable seat 52 and a lock door 53, wherein the cable seat 52 is positioned above the clamp seat 51 and is provided with an opening 54 for placing a cable, and one end of the lock door 53 is rotatably connected to the position of the opening 54 of the cable seat 52 and is used for opening and closing and fixing the opening 54 through rotation. The clamp seat 51 is used for fixing on the cross arm. The cable may be placed in the cable seat 52 and then the latch door 53 may be snapped into place to secure the cable. The locker door 53 is provided with a handle part 531, and the handle part 531 extends outward and has a handle hole 532. Therefore, the remote operation of the toggle handle portion 531 can be realized by using a bamboo pole or a tool, so that the opening and closing operation of the latch door 53 can be realized, and the operation is safer and more convenient.

On the whole, can realize the three cable on the left, the fixed of the three cable on the right, be with tower double-circuit promptly. The scheme is suitable for a 10KV same-tower double-circuit steel pipe tower, the distance between the upper and lower-layer cross arms is 700-1200mm, and the position of the wire support 5 is adjustable.
