Abstract
The utility model discloses a special rope ladder between a tower and a lead, which comprises a rope ladder body. The top end of the rope ladder body is provided with a hanger, and the bottom end of the rope ladder body is provided with a clamp device. The utility model discloses the special rope ladder, which has a simple structure, is capable of realizing safe and convenient construction and does not damage a compound insulator and is suitable for the tower and the lead.
Description
Technical field
The utility model relates to a kind of rope ladder.
Background technology
At present, the insulator of transmission line of electricity generally all is composite insulator now, will be in the conducting transmission line maintenance process by on the composite insulator upper conductor, but composite insulator does not allow to step on to step on, can have a strong impact on the trouble free service of composite insulator like this, in order to guarantee the full skirt safety of composite insulator, do not influence the lower wire work on the transmission line of electricity again, we have developed a kind of special-purpose rope ladder.
The hard ladder of our usual usefulness cannot fixing cord and shaft tower on, rope ladder then rocks back and forth, and is also dangerous. in order to eliminate hidden danger and the difficulty that above-mentioned reason is brought, we have developed this novel rope ladder.
The utility model content
The purpose of this utility model provides a kind of simple in structure, for the construction of safe ready does not damage composite insulator again, is adapted at the special-purpose rope ladder that uses between iron tower and the lead.
For achieving the above object, the utility model adopts following technical scheme: a kind of special-purpose rope ladder from the shaft tower to the lead, comprise the rope ladder body, and rope ladder body top is provided with hook, and the bottom is provided with fastener.
Described fastener comprises fastening block, and fastening block is provided with click apparatus, is wound with restraint zone on the wheel shaft of ratchet, and restraint zone links to each other with the bottom of rope ladder body.
Described fastening block is provided with the U-shaped draw-in groove, and wherein a draw-in groove arm is provided with fastening bolt.
Described ratchet comprises end of matching with ratchet and the handle that oppositely extends with above-mentioned end.
Described fastening block is provided with set bolt, is fixedly arranged on the set bolt after rope ladder body bottom is twined at described restraint zone middle part.
The beneficial effects of the utility model are: 1. mounting method is simple, increases work efficiency.2. safe and reliable, can reach the requirement of hard ladder by the tension of ratchet, so just guarantee personnel's safety.3. because the length of rope ladder can be stretched, the composite insulator of any length can use.The utlity model has easy for installation, simple operation, the advantage of highly versatile.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
A kind of special-purpose rope ladder from the shaft tower to the lead by illustrated in figures 1 and 2 comprises rope ladder body 2, and rope ladder body 2 tops are provided with hook 1, and the bottom is provided with fastener.Described fastener comprises fastening block 11, and fastening block 11 is provided with click apparatus and set bolt 9, is wound with restraint zone 4 on the wheel shaft 10 of ratchet 5, and restraint zone 4 middle parts were fixedly arranged on the set bolt 9 after twining the bottom 3 of rope ladder body 2.Fastening block 11 bottoms of click apparatus downside are provided with U-shaped draw-in groove 8, are positioned on the draw-in groove arm of fastening block 11 bottoms vertically to be provided with fastening bolt 7.Described ratchet 6 comprises end of matching with ratchet 5 and the handle 12 that oppositely extends with above-mentioned end.(the pawl ratchet device is a prior art so be not described in detail.）
During use, the hook 1 of rope ladder can be suspended on the lead, utilize fastening bolt 7 and U-shaped draw-in groove 8 that fastening block 11 is fixed on the shaft tower, when needs reclaim restraint zone 4, but forward rotation ratchet 5, simultaneously, regain restraint zone 4, rope ladder can be strained, but the construction of safe ready.When need loosen rope ladder, can press the handle 12 of ratchet 6, ratchet 6 breaks away from ratchet 5, and the ratchet 5 that reverses is simultaneously emitted restraint zone 4, and rope ladder can relax.
