Abstract
The utility model relates to an upturned three-wheeled pulley used for electric paying out. The upturned pulley is a pulley (2) coaxially arranged in an integrated way by three blocks. The utility model can put three ropes pulled by one hauling rope in an electric paying out construction into the three pulleys accurately without any human assistance and no artificial over climbing or rope distribution is needed when the rope head passes through the pulley, therefore, the operational procedure for operators is simplified effectively, the security risk is lowered and the efficient operation of construction is guaranteed.
Description
Technical field
The utility model belongs to electric power releasing pulley technical field of structures.
Background technology
Utilize the remote control airship unwrapping wire to enter the construction that routinizes of electric power stringing at present, carry an elementary messenger, run through each basic iron tower of crossing over section, realize crossing in the air by dirigible.Yet, after dirigible is put logical elementary messenger, realize that every basic iron tower has five or eight pull rope, " one leads three " (three ropes of a rope band) construction that will utilize the elementary messenger of this root to carry out twice or three times realizes.Prior art be adopt three independent respectively each of installing only with a pulley towards the sky coaster, the fag end of three ropes will coming by the traction of fag end connecting plate straddles respectively on three pulleys, to carry out follow-up unwrapping wire.But when the fag end connecting plate strides across coaster, because three coasters are installed separately, the installation site is unfixing, distance between each coaster is unfixing yet, distance between adjacent two of three ropes holding with the fag end connecting plate often can not and adjacent two of three coasters between distance coincide, three ropes are difficult to be installed on exactly in the outer rim groove of three independent pulleys, and what needs were artificial crossed coaster to fag end, and manually three ropes was placed in respectively in each pulley.This mode need stop traction and carry out separated time, and not only holding time simultaneously, carries out separated time under the stressed bigger situation of rope, also has bigger potential safety hazard.In addition, when coaster was installed in lower position, stressed rope raised up and usually can rub with the members such as support that coaster is installed, and makes the rope fracture, causes construction to interrupt.
Summary of the invention
The purpose of this utility model provides a kind of artificial auxiliary three ropes of " leads three " can being placed to exactly in three pulleys of coaster that do not need in order to solve the deficiency that above-mentioned prior art exists just, save time, efficiently, safe electric power unwrapping wire is towards the sky three-fold block.
The purpose of this utility model is achieved by the following technical solution.
The electric power unwrapping wire is towards the sky three-fold block, and it is three coaxial pulleys that are installed as one towards the sky coaster.
The utility model correspondence above three pulleys is equipped with one or three fabric wheels; On the top of support the triangle link plate is installed.
Because three pulley coaxles towards the sky coaster are installed as one, the fixed-site of three pulleys, it is also fixing that the pulley outer rim is used to accept the groove location of rope, when carrying out " one leads three " construction, as long as adopt the suitable fag end connecting plate of size, make distance between adjacent two of three ropes of its pulling equal distance between the outer rim groove of adjacent two pulleys of coaster, just can in striding across the process of coaster, the fag end connecting plate exactly three ropes be installed in the groove of three pulleys, fag end no longer needs artificial crossing and separated time during by coaster, effectively simplified operating personnel's operation sequence, reduce security risk, ensure the efficient operation of construction.
The fabric wheel that is positioned at three pulley tops that the utility model is set, can be according to the size of the moment that raises up, selectivity is installed one or three fabric wheels, and the rope that passes pulley is pushed down, prevent that it from excessively raising up, avoid with coaster support or other member contact friction and rubbed.In cantilever tip the triangle link plate is installed, can be made the utility model that multiple use is arranged, as being used as lead or corner block.
Further set forth content of the present utility model below in conjunction with Figure of description.

Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is the schematic diagram that utilizes three lines of the utility model traction;
Fig. 4 is the line ball schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises support 3, and frame bottom is equipped with the fixed head 4 of a band draw-in groove 9, and during use, the draw-in groove 9 by fixed head 4 bottoms and fastening bolt 5 are installed in the utility model on the electric power tower.One transverse axis 8 is installed on support, is coaxially installed on the transverse axis 8 towards three pulleys 2 of sky coaster and constitutes one.Triangle link plate 1 is installed on top at support 3.Before carrying out " one leads three " construction, fabric wheel 6 is not installed earlier.As shown in Figure 3, when carrying out " one leads three " construction, elementary messenger 10 is fastened top at triangle fag end connecting plate 11, three ropes 12 that are pulled are equidistantly fastened the bottom at fag end connecting plate 11, distance between adjacent two ropes 12 with equate towards the distance between adjacent two pulleys, the 2 outer rim grooves of sky coaster, elementary messenger 10 hauls fag end connecting plate 11 and strides across coaster, and three ropes 12 that fag end connecting plate 11 is leading promptly straddle respectively on three pulleys 2.After three rope straddle mountings were good, corresponding installation one or three fabric wheels 6 above three pulleys 2 were pushed down three ropes respectively again.Three fabric wheels 6 can be coaxially installed on the support 3 with axle 7.The utility model is as long as be equipped with the fag end connecting plate of the suitable special use of size, and the fag end connecting plate directly by coaster, just can successfully be installed on trailed three ropes in three pulleys, no longer need artificial separated time, not only save time, aspect personal security, higher guarantee has been arranged also.
Claims (3)
1. the electric power unwrapping wire is towards the sky three-fold block, comprise support (3) and be installed on the support towards the sky coaster, it is characterized in that described is three coaxial pulleys (2) that are installed as one towards the sky coaster.
2. electric power unwrapping wire according to claim 1 is characterized in that towards the sky three-fold block correspondence is equipped with one or three fabric wheels (10) in three pulleys (2) top.
3. electric power unwrapping wire according to claim 1 is characterized in that towards the sky three-fold block, on the top of support (3) triangle link plate (1) is installed.
