Detailed Description

The technical scheme of the invention is further explained in detail by combining the attached drawings:

a cable hanging piece is shown in figures 1, 2 and 3 and comprises a wire hanging device 10, wherein the wire hanging device 10 comprises a pair of vertically and symmetrically arranged supporting rods 1, a pair of inclined downward movable rods 11 are symmetrically hinged to the upper ends of the two supporting rods 1, one ends, far away from the supporting rods 1, of the two movable rods 11 are mutually abutted, a bent rod 2 is transversely arranged between the two supporting rods 1, connecting rods 21 are respectively arranged between the bent rod 2 and the movable rods, and a spring 22 in a stretching state is horizontally arranged between the two connecting rods 21; a clamping device 23 is arranged between the spring one 22 and the movable rod one 11 between the two connecting rods 21.

The lower ends of the two support rods 1 are symmetrically hinged with a pair of inclined upward movable rods 12, one ends, away from the support rods 1, of the two movable rods 12 are mutually abutted, a second spring 121 in a stretching state is arranged between the two movable rods 12 and the adjacent support rod 1, and a guide rail 122 is arranged between the bent rod 2 and the two movable rods 12 on the inner side of the support rod 41.

Further, still include vaulting pole 4, vaulting pole 4 includes handle 41, and handle 41 upper end is provided with U type pole 42, and the inboard at the both ends of U type pole 42 is provided with a pair of ratchet 43 mechanism, including ratchet 43 and pawl 44, the both sides of ratchet 43 are provided with the straight-teeth gear 45 that the diameter is greater than ratchet 43, and the outside of two bracing pieces 1 bottoms sets up the rack 46 with straight-teeth gear 45 engaged with, and ratchet 43 mechanism makes vaulting pole 4 unable upward movement on bracing piece 1, only can the downstream.

Further, the clamping device 23 includes a pair of clamping plates 232 arranged transversely, grooves are arranged inside the clamping plates 232, and the clamping plates 232 are connected and fixed with the U-shaped rod 42 through a supporting rod 231.

Further, the guide rail 122 is an arc-shaped rod with an upward opening.

The working principle is as follows:

1. firstly, the pawl 44 is opened and the rack 46 on the wire hanger 10 is meshed with the spur gear 45 on the support rod 4, then the support rod 4 is lifted upwards, when the steel strand 52 contacts the point A, the push rod 4 is lifted continuously, the movable rod I11 is opened, and the spring I22 is further stretched. Meanwhile, the clamping device 23 is opened, when the steel strand 52 just enters between the two clamping plates 232 of the clamping device 23, the first spring 22 enables the clamping device 23 to clamp the steel strand 52, so that the wire hanger 10 is fixed on the steel strand 52, and finally the ratchet wheel 43 can rotate by pulling downwards, so that the straight gear 45 and the rack 46 can be meshed for transmission, and the support rod 4 is separated from the support rod 1 of the wire hanger 10.

2. After the wire hanger 10 is fixed, the cable 51 is lifted up by using the stay bar 4, when the cable passes through the point B, an upward force is generated, so that the two movable bars 12 are separated, the cable 51 is placed on the guide rail 122, and the work of erecting the cable 51 is completed.
