Abstract

The utility model discloses an adjustable lifter of a power transmission line overhead ground wire, which is applied to a wire clamp for replacing an overhead ground wire and comprises a lead screw, a ratchet wrench and a pressure bearing. The adjustable lifter is technically characterized in that a threaded sleeve is arranged on the upper portion of the lead screw, the ratchet wrench is positioned on the threaded sleeve, the pressure bearing is arranged on the lower side of the threaded sleeve, and a hook is arranged on the lower portion of the lead screw. The lifter further includes a horizontal suspension plate connected with a transverse rod of a tower, and when the transverse rod portion of the power transmission tower is different in structure, a triangular support can be added according to needs, and the horizontal suspension plate is mounted on the tower by the aid of the triangular support and a vertical suspension. The adjustable lifter has the advantages of convenient utilization, fine universality, rapid wire clamp replacement and simple structure.

Description

Transmission line overhead ground wire adjustable type lifter
Technical field
The utility model relates to a kind of hand-operated tools that upkeep operation is used in transmission line, especially a kind of transmission line overhead ground wire adjustable type lifter.
Background technology
Transmission line has characteristics such as quantity is many, distribution is wide, annex is various, and along with rapid development of national economy, to the also raising day by day of quality requirement of power supply service, the upkeep operation of transmission line more and more is subjected to the attention of power supply department.As the peaceful sesame II of 110kv on November 6 coil holder vacant lot line seriously corroded in 2009, might cause the overhead ground wire broken string at any time, cause serious harm to personnel and equipment, therefore need in time carry out the work of changing overhead ground wire.And when changing overhead ground wire, ground wire just can need be carried out maintenance activity after sprung parts is erected.Amount to 9 days 140 hours time spent in whole maintenance, 32 basic shaft towers are not owing to there is advanced Work tool to change the overhead ground wire of seriously corroded, and it is very difficult to work, consuming time very long, incur loss through delay electric power feeding time and reach 5 hours.Find in the work that because of there not being advanced Work tool to change the overhead ground wire wire clamp be to incur loss through delay the key point of sending electricity.Rely on the landing work that tactics of human sea on the shaft tower solves overhead ground wire in the work, especially need strong operating personnel could tackle big span, overhead ground wire that weight is big, it is time-consuming relatively to require great effort, if and misoperation, easily cause the damage of shoulder and waist, overhead ground wire also may take place come off and cause earth fault to the staff.Therefore press for a kind of service kit, so that the wire clamp of convenient replacing overhead ground wire.
The utility model content
The technical problems to be solved in the utility model provides a kind of easy to use, replacing wire clamp transmission line overhead ground wire adjustable type lifter rapid and simple in structure.
For solving the problems of the technologies described above, first kind of technical scheme that the utility model is taked is: a kind of transmission line overhead ground wire adjustable type lifter, comprise leading screw, ratchet wrench and pressure bearing, its key technology is to be provided with swivel nut on described leading screw top, on swivel nut, be positioned with ratchet wrench, below swivel nut, be provided with pressure bearing, be provided with hook in the leading screw bottom; Described lifter also comprises and is used for the horizontal link plate that is connected with the cross-arm of shaft tower.
Preferably, above-mentioned horizontal link plate body shape is dull and stereotyped, is provided with slotted hole on flat board, is provided with hook at an end of flat board.
Second kind of technical scheme that the utility model is taked is: a kind of transmission line overhead ground wire adjustable type lifter, comprise leading screw, ratchet wrench and pressure bearing, its key technology is to be provided with swivel nut on described leading screw top, on swivel nut, be positioned with ratchet wrench, below swivel nut, be provided with pressure bearing, be provided with hook in the leading screw bottom; Described lifter also comprises and is used for the combination link plate that is connected with second angle bar on the shaft tower cross-arm, and described combination link plate comprises A-frame and by bolt and the affixed vertical link plate of A-frame.
Adopt the beneficial effect that technique scheme produced to be: to adopt the utility model that overhead ground wire is promoted, the replacing wire clamp is quick and easy, need three people to be reduced to a present people from original replacing one pedestal vacant lot line, and be reduced to about 20 minutes the time by original about 2 hours; Because it is convenient to change, thereby reduce operating personnel's labour intensity, improved operational security; Mechanical strength of the present utility model is higher, and is in light weight, easy to make, and has good shaft tower adaptability and versatility, carries out adaptive adjustment according to the difference of transmission tower shape.
