The purpose of the utility model is to provide a power transmission line pole and tower lifter that can lift objects on the pole tower, is relatively quick and labor-saving, facilitates the cooperation of ground personnel, can greatly reduce the operating intensity of personnel on the tower, and reduces the risk of high-altitude operations.

The above-mentioned purpose is achieved by the following technical solutions: develop a transmission line pole tower lifter, which is characterized in that: the lifter has a U-shaped clamp formed by folding a long steel plate in half, and one side of the U-shaped clamp is There are screw holes, the screw holes are equipped with fastening bolts, and the other side is provided with a hanging joint for hanging ropes.

A crank is provided at the outer end of the fastening bolt.

The hanging joint is a hanging ring.

A hook is hung on the hanging ring, and a rotating shaft is installed at the lower end of the hook, and a pulley is arranged on the rotating shaft.

Described hanging joint is a pulley, and the pulley shaft is fixed on one side of U-shaped clamping iron, and the outside of pulley is equipped with rocking handle.

Described pulley is one-way pulley.

Described pulley is the pulley block that is made up of fixed pulley and movable pulley.

The beneficial effects of the utility model are: the clamping iron is fixed on the crossarm of the tower, and the objects can be lifted to the top of the tower by pulling the rope, which is convenient for installation, saves time and effort, facilitates the cooperation of ground personnel, and significantly reduces the labor intensity and labor intensity of the personnel on the tower. Risk pressure, it is expected to become an essential equipment for transmission line maintenance operations.

Detailed ways

The general design of the utility model is to clamp on the pole tower with a U-shaped clamp iron, and carry and lift articles above the pole tower by hanging joints and ropes. Introduce four kinds of embodiments below in conjunction with accompanying drawing:

The first embodiment: Fig. 1 Fig. 2 has introduced a kind of power transmission line pole tower extractor, and its main component is a U-shaped clamping iron 1 that is formed by the long steel plate folded in half, and one side of U-shaped clamping iron 1 is provided with screw. Holes 2 and screw holes 2 are equipped with fastening bolts 3, and the other side of the U-shaped clamping iron 1 is provided with a hanger 4 that can be articulated with a rope 9. There are various structural forms of the hanging joint 4, and a circular or partially circular hanging ring 5 is illustrated in FIG. 1 . This hanging ring 5 itself just can pass through rope 9 and lift article. Can also as shown in Figure 3, hang a set of pulley 8 by hook 7 below hanging ring 5, rope 9 is worn on the pulley 8, lifts and hangs article more labor-saving.

Combined with Figure 4, it can be seen that the U-shaped clamp iron 1 of this object lifter is clamped on the crossarm of the pole tower, or on other similar parts, one end of the rope is connected to the heavy object, and the other end is operated by the ground personnel, and the rope is pulled. Lift heavy objects onto the tower. The operators on the tower cooperate with the ground personnel to easily get the required materials, and the maintenance work can be carried out smoothly.

The second embodiment: as shown in Figure 5, the main part of this power transmission line pole tower extractor is a U-shaped clamping iron 1 formed by folding a long steel plate in half, and one side of the U-shaped clamping iron 1 has a screw hole 2. The screw hole 2 is equipped with a fastening bolt 3, and the outer end of the fastening bolt is provided with a crank handle 10. The other side of U-shaped clamp iron 1 is provided with the hanger 4 that can hang rope 9. Described hanger is a pulley 8, and the outside of pulley 8 is equipped with rocking handle 11.

During use, the U-shaped clamping iron 1 is stuck on the cross arm of the pole tower, and the personnel above the pole tower can lock the U-shaped clamping iron 1 on the cross arm by shaking the crank handle 10 on the fastening bolt 3 without using a wrench. Rope one end connects heavy object, and the personnel on pole tower shakes pulley handle 11, can rotate pulley, coils rope 9, lifts and lifts article, can omit ground to cooperate personnel, when the ground is short of manpower, can emergency with this method.

The third embodiment: the main parts of this power transmission line pole tower extractor are basically the same as the second embodiment, and there is also a U-shaped clamp 1, and one side of the U-shaped clamp 1 has a screw hole 2, and the screw hole 2 is equipped with fastening bolt 3, and U-shaped clamping iron 1 other side is provided with hanging joint 4, and hanging joint 4 is a pulley 8, and the outside of pulley 8 is equipped with rocking handle 11. Its characteristic is as shown in Figure 6, described pulley 8 is a kind of one-way pulley 12. The one-way pulley 12 includes an inner wheel 13 , an outer wheel 14 , a one-way tooth 15 , a one-way pawl 16 and a return spring 17 . The effect of one-way pulley 12 is to only be able to rotate to an outer wheel 14 directions, can not reverse. Adopt this one-way pulley 12, can not only go up when hoisting article, can not descend, more energy-saving, safety is higher, if need when conveying article downwards, exchange the other side rope and get final product.

Fourth embodiment: as shown in FIG. 7 , the pulley 8 is a pulley block composed of a fixed pulley 18 and a movable pulley 19 . According to the mechanical characteristics of the pulley blocks, each pulley block can save half of the effort. If there are multiple pulley blocks, the lifting operation will be more labor-saving.
