Description

Overhead transmission line ground wire optical fiber cable fitting changes support
technical field:
The present invention relates to a kind of power circuit maintenance tool, particularly relate to a kind of overhead transmission line ground wire optical fiber cable fitting and change support.
background technology:
China's electrical distribution is uneven, need long distance powedr transmission, in order to reduce the wastage and improve power transmission efficiency, adopt ultra high voltage and super UHV transmission more and more, correspondingly the diameter of power transmission line and ground wire is also increasing, its weight is also very large, when needing repairing or change power transmission line or ground insulator, bucket crane is needed power transmission line or ground wire to be sling, efficiency is low and cost is high, and for the place that bucket crane can not go, replacing power transmission line or ground wire can only adopt manpower to pull or jacking, require great effort time-consuming, and there is the hidden danger of personal injury.
summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, easy to use, evenly can lift by crane ground wire and the high overhead transmission line ground wire optical fiber cable fitting of operating efficiency changes support.
Technical scheme of the present invention is: a kind of overhead transmission line ground wire optical fiber cable fitting changes support, containing column, the lower end of described column is connected with the inner ends thereof formula of a strut respectively, the outer end of two described struts arranges an assembly pulley respectively, the outer end of two described struts is connected with the upper end of described column with oblique pull steel wire rope respectively by shackle, two described assembly pulleys are placed respectively a hoisting wirerope, the lower end of two described hoisting wireropes is connected with a line hanging hook respectively, and the upper end of two described hoisting wireropes is connected with wire grip respectively.
The outer end of described strut is provided with sealing screw.Described shackle is U-shaped structure, and two perforated wall is connected with described column upper end thereof or with the wheel shaft rotary type of described assembly pulley respectively.Described column lower end is fixed on pole tower ground wire support by connecting bolt.
The invention has the beneficial effects as follows:
1, the present invention with pole tower ground wire support for anchor point, utilize the principle of goat's horn pole, by the parts such as column, strut, steel wire rope and wire grip balanced hoisting ground wire or optical cable simultaneously, the vertical load of ground wire or optical fiber cable fitting is transferred on shaft tower, realize the operations such as ground insulator replacing, the replacing of optical cable pre reeled silk type wire clamp, save the activity duration, decrease the labour intensity of personnel, ensure that the safety of personnel and equipment.
2, the present invention is provided with assembly pulley in one end of strut, can reduce the moving resistance of hoisting wirerope, laborsavingly saves time, and in addition, the other end of strut is connected with column rotary type, can rotate, and is convenient to pull-up ground wire or cable.
3, column of the present invention is fixed by connecting bolt and pole tower ground wire support, and be convenient to dismounting, operating efficiency is high, and can reuse.
4, the end of strut of the present invention is provided with sealing screw, can prevent assembly pulley from coming off, and improves stability and the fail safe of work.
5, the present invention reasonable in design, easy to use, evenly can lift by crane ground wire and operating efficiency is high, it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing illustrates:
Fig. 1 is the structural representation that overhead transmission line ground wire optical fiber cable fitting changes support;
Fig. 2 is the end view of Fig. 1 central post.
embodiment:
Embodiment: see in Fig. 1 and Fig. 2, figure, 1-line hanging hook, 2-brazier head screw, 3-assembly pulley, 4-wire grip, 5-shackle, 6-column, 7-strut, 8-oblique pull steel wire rope, 9-hoisting wirerope, 10-seals screw, 11-pole tower ground wire support, 12-connecting bolt.
Overhead transmission line ground wire optical fiber cable fitting is changed support and is contained column 6, wherein: the lower end of column 6 is connected with the inner ends thereof formula of a strut 7 respectively, the outer end of two struts 7 arranges an assembly pulley 3 respectively, the outer end of two struts 7 is connected with the upper end of column 6 with oblique pull steel wire rope 8 respectively by shackle 5, two assembly pulleys 3 are placed respectively a hoisting wirerope 9, the lower end of two hoisting wireropes 9 is connected with a line hanging hook 1 respectively, and the upper end of two hoisting wireropes 9 is connected with wire grip 4 respectively.
The outer end of strut 7 is provided with sealing screw 10.Shackle 5 is U-shaped structure, and two perforated wall is connected with column 6 upper end thereof or with the wheel shaft rotary type of assembly pulley 3 respectively.
During use, column 6 lower end is fixed on pole tower ground wire support 11 by connecting bolt 12, adjustment wire grip 4 makes hoisting wirerope 9 move downward, thus make line hanging hook 1 stick ground wire, then, then adjust wire grip 4 hoisting wirerope 9 is moved upward, pull-up ground wire, the vertical load of ground wire or optical fiber cable fitting is transferred on shaft tower, realizes the operations such as ground insulator replacing, the replacing of optical cable pre reeled silk type wire clamp.Because two struts 7 are symmetrical arranged, thus can simultaneously balanced hoisting ground wire or optical cable, prevent from, be convenient to work.
The above is only preferred embodiment of the present invention, and not do any pro forma restriction to the present invention, every any simple modification done according to technical spirit of the present invention, all still belongs in the scope of technical solution of the present invention.
