Abstract
The utility model discloses an operating device of a line lifter lead screw for a transmission line, which is provided with a screw sleeve matched with a line lifter lead screw, a ratchet wrench is fixedly sleeved on the screw sleeve, and an operation ring is arranged at an operation end of the ratchet wrench. The operating device achieves long-distance operation of a line lifter, thereby effectively preventing a safety distance from harming human bodies. An operator can hold a pole with one hand and operates the line lifter with a one hand, thereby improving stability of standing and being labor-saving, convenient and fast in operation. The operating device has the advantages of being simple in structure, convenient to use and the like.
Description
Technical field
The utility model belongs to transmission line erecting tools technical field, particularly a kind of transmission pressure line lifter screw mandrel operating means.
Background technology
In the electric power system Overhead Transmission Line Construction; The conventional method of carrying out transmission pressure lifting installation is normally stood on the cross-arm of tower bar by the operator; There is the outstanding rope of simple and easy thread-lifting hook that two leads are promoted to the height that needs by root through two root systems; And will hang rope and be bundled in respectively on the cross-arm, after treating lead is strained and fixed, untie again and take off outstanding rope.The major defect one of this method is to lean on manpower to promote two leads one by one fully, wastes time and energy, and labour intensity is big, and operating efficiency is low; The 2nd, thread-lifting hook adopts the steel plate cutting to form, and makes coarsely, causes easy damaged lead when carrying line; The 3rd, altitude hot-line operation, supporting surface is narrow and small, astasia, not only very inconvenience of operation, and seriously have potential safety hazard.At present, special-purpose line lifter is adopted in the construction that has, and this line lifter is by carrying the line suspension hook, carrying the line plate and screw mandrel is formed; The screw mandrel upper end is provided with nut, and when construction, nut places on the cross-arm of power transmission line column bar; Through rotating nut, carry the line plate, propose the up of line suspension hook through the screw mandrel drive.Though the operation of this line lifter is easier, the fail safe of carrying line than conventional method improves greatly, because leading screw belongs to metal tools, caused in the operation process safe distance shortening.In this case, the operating personnel need stand on the cross-arm and move nut with spanner, carries out the lifting of lead, because the position limit, it is not too convenient that workman's operation is still felt, and especially during live line working, safe distance is to the serious threat of personal safety formation.
The utility model content
The purpose of the utility model is to provide a kind of can effectively eliminate the threat of safe distance to operating personnel's personal safety, simple to operate, high in efficiency and convenience, the transmission pressure line lifter screw mandrel operating means that labour intensity is low, operating efficiency is high.
The technical scheme that purpose adopted that realizes the utility model is: a kind of transmission pressure line lifter screw mandrel operating means, have a swivel nut that cooperates with the line lifter screw mandrel, and fixed cover is equipped with ratchet spanner on the swivel nut, and the operating side of ratchet spanner is provided with the operation ring.
The transmission pressure line lifter screw mandrel operating means of the utility model; Through the setting of ratchet spanner, realized line lifter than remote operation, thereby the threat of effectively having avoided safe distance to cause to the person; And operating personnel can buttress the tower bar on the other hand; The one-handed performance line lifter, and strengthened the steadiness of standing thus, operate also more laborsaving quick.Advantages such as this device has simple in structure, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, the transmission pressure line lifter screw mandrel operating means of the utility model is the swivel nut 1 that cooperates with line lifter screw mandrel 4 with, and fixed cover is equipped with ratchet spanner 2 on the swivel nut 1, and the operating side of ratchet spanner 2 is provided with operation ring 3.Wherein, ratchet spanner can directly be purchased on market, and its structure repeats no more.
This lever operating device can use said swivel nut 1 to replace the nut of line lifter in use, is screwed in screw mandrel 4 upper ends of line lifter, and line lifter is passed through swivel nut 1 rotating hanging on the cross-arm of power transmission tower bar.When promoting lead, operating personnel may stand in the junction of cross-arm and tower bar, hand insulating bar, and the hanging hang structure of insulating bar front end is inserted in the said operation ring 3, and reciprocating sliding ratchet spanner 2 can be realized the lifting of transmission pressure.Because than remote operation, thereby the threat of effectively having avoided safe distance to cause to the person, and operating personnel can buttress the tower bar on the other hand, the one-handed performance line lifter, thereby strengthened the steadiness of standing, operate also more laborsaving fast.
