Abstract
The utility model discloses an anti-slide head of an insulating flexible ladder for overhauling a high-voltage line. According to the anti-slide head, holes (3) are symmetrically formed in the periphery of the edge of a pulley (2), and dowels (4) are arranged in the holes (3); the flexible ladder can freely slide along the high-voltage line by removing the dowels (4) and can stop at any place of the high-voltage line by installing the dowels (4). Compared with the prior art, the anti-slide head disclosed by the utility model is especially convenient for an operator to stop on the high-voltage line to overhaul the high-voltage line, thus facilitating the normal working of the operator.
Description
Technical field
The utility model belongs to power transmission lines overhauling instrument, especially a kind of high-voltage line insulated flexible ladder.
Background technology
Carrying out ultra-high-tension power transmission line when maintenance, often will use high-voltage line insulated flexible ladder, the rope ladder head of this high-voltage line insulated flexible ladder is all the hook of U-shaped conventionally, in the hook of U-shaped, be provided with pulley, can hang on the line, also can slide along circuit, use more for convenience, but, if when maintainer need to be parked in the enterprising line operate of certain circuit, this rope ladder head also easily along circuit from line slip, brought inconvenience to operating personnel's normal operation.
Summary of the invention
Technical problem to be solved in the utility model is to provide the anti-slippery fellow of a kind of high-voltage line insulated flexible ladder, not only can slide along circuit, also can be parked in the enterprising line operate of certain circuit, be not easy along circuit from line slip, bring convenience to operating personnel's normal operation.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is to comprise U-shaped hook and be arranged on the pulley on U-shaped hook, it is characterized in that: the edge of described pulley around symmetry be provided with at least one hole, in hole, be provided with pin.
Described pin can for cottor pin, can be also cylindrical pin, the other end of cylindrical pin hinged be provided with folding hook.
The utility model is by the hole that arranges of symmetry around the edge of pulley, pin is set in hole, take down pin, rope ladder can be free to slide along high-tension line, set up pin, can make rope ladder be parked in arbitrary place of high-tension line, compared with prior art, the special handled easily personnel of the utility model are parked on high-tension line and overhaul, and have brought convenience to operating personnel's normal operation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment 2.
Fig. 4 is the structural representation of the utility model embodiment 3.
Shown in figure: 1 is U-shaped hook, and 2 is pulley, and 3 is hole, and 4 is pin, 5 is folding hook.
The specific embodiment
embodiment 1:with reference to Fig. 1-Fig. 2, for the structural representation of the utility model embodiment 1, pulley 2 is arranged on the U-shaped hook 1 on high-voltage line insulating flexible ladder head, the symmetrical hole 3 that is provided with around the edge of pulley 2, in hole 3, be provided with pin 4, pin 4 is cylindrical, hook 5 is rolled in hinged being provided with of the other end at cylindrical pin 4, when use, pulley 2 is shelved on high-tension line, drag rope ladder, pulley 2 can move freely on high-tension line, when operating personnel need to be parked in while overhauling on high-tension line, can insert pin 4, 5 bendings of folding hook are come, prevent that pin 4 from coming off, in the time that pulley 2 rotates, wire on high-tension line can be blocked by pin 4, play the effect of fixed block 2, operate convenient, after operation, can be by straight folding hook 5 plates, take out pin 4, pulley 2 again can normal rotation.
embodiment 2:with reference to Fig. 3, be the structural representation of the utility model embodiment 2, compared with embodiment 1, the main distinction of the present embodiment is: pin 4 is cottor pin, also can play same effect.
embodiment 3:with reference to Fig. 4, for the structural representation of the utility model embodiment 3, compared with embodiment 1, the main distinction of the present embodiment is: in embodiment 3, around the edge of pulley, be provided with multiple holes, in the suitable hole that can as required pin be inserted, more convenient to use.
Claims (3)
