Abstract
The invention relates to a slide-type anti-string-fall wire clamp, which comprises an aluminium twisted wire and a wear-resisting pre-twisted wire. The wear-resisting pre-twisted wire sleeves the aluminium twisted wire. The slide-type anti-string-fall wire clamp also comprises a support and a pulley gear arranged in the support. The pulley gear comprises at least two main pulleys and one trip-proof pulley. The two main pulleys are arranged at the left and right two sides at the bottom portion of the support. The trip-proof pulley is arranged above the place between the two main pulleys. The distance between the lower end of the trip-proof pulley and the upper end of the corresponding main pulley is not smaller than the external diameter of the aluminium twisted wire. The wear-resisting pre-twisted wire is arranged at the two ends of the support. The aluminium twisted wire passes through the wear-resisting pre-twisted wire, the upper ends of the main pulleys and the lower end of the trip-proof pulley, and slides in the wear-resisting pre-twisted wire. The slide-type anti-string-fall wire clamp is simple in structure and convenient to use and install; through the arrangement of the wear-resisting pre-twisted wire, slide safety of the aluminium twisted wire can be ensured effectively; and meanwhile, through the arrangement of the main pulleys and the trip-proof pulley, slide smoothness of the aluminium twisted wire can be ensured, and safety of towers is guaranteed.

Move between Si.
As a preferred embodiment of the present invention, described support is also associated with hanging head and U-shaped link；U-shaped link upper end connects has hanging deck, support to be connected by fishbolt with hanging head, and hanging head is connected by movable bolt with U-shaped link.As a preferred embodiment of the present invention, described head pulley is solid by fixing axle
Surely being connected on support, anti-jump pulley is movably connected on support by string screw.
As a preferred embodiment of the present invention, the quantity of described head pulley is 3, along frame bottom arc shooting；Corresponding, described anti-jump pulley is 2, is uniformly laid between adjacent main pulley.
The invention has the beneficial effects as follows: present configuration is simple, easy to install and use, by arranging wear-resisting type preformed armor rods, it is possible to effectively protect the slip safety of aluminum stranded conductor, meanwhile, anti-jump pulley and head pulley are set,
Ensure that the slip of aluminum stranded conductor is unobstructed, the safety of protection electricity tower；It addition, in the case of aluminum stranded conductor ruptures, by the effect of anti-jump pulley, it is possible to the safety of post-rift aluminum stranded conductor rear end part and tower is effectively ensured, the bounce preventing aluminum stranded conductor fracture from producing damages other aluminum stranded conductors and tower.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
Reference in figure: aluminum stranded conductor 1, wear-resisting type preformed armor rods 2, support 3, head pulley 4, anti-jump pulley 5, hanging head 6, U-shaped link 7, fishbolt 8, movable bolt 9, fixing axle 10, string screw 11, hanging deck 12.
