Description

Electric power line pole tower article carrying device
Technical field
The present invention relates to a kind of electrician tool, i.e. a kind of electric power line pole tower article carrying device.
Background technology
In Maintenance of Electric Transmission Line process, operating personnel sometimes will to lifting article on shaft tower.The multiplex rope attachment of existing extract mode, then lift rope by people, article are risen to shaft tower.Because the operating personnel on shaft tower are in work high above the ground, operate very inconvenient, lift article compare effort, and operating efficiency is very low, and has certain risk.
Summary of the invention
The object of this invention is to provide one can to lifting article above shaft tower, and fast laborsaving, is convenient to ground staff and coordinates, significantly can alleviate the manipulation strength of personnel on tower, reduce the electric power line pole tower article carrying device of work high above the ground risk.
Above-mentioned purpose is realized by following technical scheme: develop a kind of electric power line pole tower article carrying device, be characterized in: described article carrying device has a U-shaped gib be folded to form by strip-shaped steel plate, the side of U-shaped gib has screw, screw is furnished with fastening bolt, and opposite side is provided with the hanging joint that can mount rope.
The outer end of described fastening bolt is provided with crank.
Described hanging joint is a link.
Described link hangs with hook, and rotating shaft is installed in hook lower end, and pulley is equipped with in rotating shaft.
Described hanging joint is a pulley, and pulley spindle is fixed on the side of U-shaped gib, and rocking handle is equipped with in the outside of pulley.
Described pulley is unidirectional pulley.
The assembly pulley that described pulley is made up of fixed pulley and movable pulley.
The invention has the beneficial effects as follows: gib is fixed on the cross-arm of shaft tower, pull rope can to lifting article above shaft tower, easy for installation, time saving and energy saving, be convenient to ground staff coordinate, significantly alleviate labour intensity and the risk pressure of personnel on tower, be expected the indispensable equipment becoming power transmission lines overhauling operation.

Embodiment
The total design of the present invention is stuck on shaft tower with U-shaped gib, by hanging joint and rope to lifting article above shaft tower.Four kinds of embodiments are introduced below in conjunction with accompanying drawing:
The first embodiment: Fig. 1 Fig. 2 describes a kind of electric power line pole tower article carrying device, its critical piece is a U-shaped gib 1 be folded to form by strip-shaped steel plate, the side of U-shaped gib 1 has screw 2, and screw 2 is furnished with fastening bolt 3, and the opposite side of U-shaped gib 1 is provided with the hanging joint 4 that can mount rope 9.The version of hanging joint 4 has multiple, and what exemplify in Fig. 1 is the link 5 of a circle or part circular.This link 5 inherently can penetrate rope 9 lifting article.As shown in Figure 3, can also mount a set of pulley 8 at link 5 below by hook 7, rope 9 is through on pulley 8, and lifting article are more laborsaving.
Composition graphs 4 is visible: the U-shaped gib 1 of this article carrying device is stuck on the cross-arm of shaft tower, or on other similar parts, rope one end connects weight, and the other end is operated by ground staff, pulls rope, can on weight lifting to shaft tower.Operating personnel's tie surface personnel above shaft tower, easy to doly take required material, and upkeep operation is smooth.
The second embodiment: as shown in Figure 5, the critical piece of this electric power line pole tower article carrying device is a U-shaped gib 1 be folded to form by strip-shaped steel plate, the side of U-shaped gib 1 has screw 2, and screw 2 is furnished with fastening bolt 3, and the outer end of fastening bolt is provided with crank 10.The opposite side of U-shaped gib 1 is provided with the hanging joint 4 that can mount rope 9.Described hanging joint is a pulley 8, and rocking handle 11 is equipped with in the outside of pulley 8.
During use, U-shaped gib 1 is stuck on the cross-arm of shaft tower, and the personnel above shaft tower need not use spanner, and the crank 10 on shake fastening bolt 3 can be locked at U-shaped gib 1 on cross-arm.Rope one end connects weight, and the personnel on shaft tower shake pulley rocking handle 11, i.e. rotatable pulley, coil rope 9, lifting article, can omit ground and coordinate personnel, when ground is understaffed, can meet an urgent need in this way.
The third embodiment: the critical piece of this electric power line pole tower article carrying device is substantially identical with the second embodiment, also a U-shaped gib 1 is had, the side of U-shaped gib 1 has screw 2, screw 2 is furnished with fastening bolt 3, U-shaped gib 1 opposite side is provided with hanging joint 4, hanging joint 4 is pulleys 8, and rocking handle 11 is equipped with in the outside of pulley 8.As shown in Figure 6, described pulley 8 is a kind of unidirectional pulleys 12 to its feature.Unidirectional pulley 12 comprise interiorly take turns 13, foreign steamer 14, unidirectional tooth 15, one-way clutch 16 and return spring 17.The effect of unidirectional pulley 12 can only be rotated to foreign steamer 14 direction, can not reverse.Adopt this unidirectional pulley 12, can not rise during lifting article, can not decline, more laborsaving, fail safe is higher, if when needing to carry article downwards, exchange opposite side rope.
4th kind of embodiment: as shown in Figure 7, the assembly pulley that described pulley 8 is made up of fixed pulley 18 and movable pulley 19.From the mechanical property of assembly pulley, each assembly pulley can laborsaving half, if be furnished with multiple assembly pulley, lifting operation is more laborsaving.
