Abstract
The utility model relates to an earth electrode raiser used in the maintenance of a power circuit. The earth electrode raiser comprises a winding reel for a steel rope, which is assembled on a U-shaped pedestal; wherein, both ends of the winding reel stick out from the two lateral plates of the U-shaped pedestal and are respectively provided with an anti-gyration ratchet wheel and a handle-connecting shaft head; a pawl on which a spring is assembled is mated with the ratchet wheel; the end of the steel rope is provided with a connecting hook; a U-shaped connector is hinged with the lower side of the bottom plate of the U-shaped pedestal; a connecting cross shaft is arranged on the lower part of the connector; and a raising hook is hinged with the cross shaft. The earth electrode raiser, which is characterized by simple structure and convenient use, can effectively reduce the labor intensity in the maintenance operation of an earth electrode, increase working efficiency and ensure the safety and quality of the maintenance operation.
Description
Technical field
The utility model relates to a kind of earth electrode lifter that is used for the power circuit maintenance
Background technology
Earth electrode is the facility that the anti-thunder and lightning of overhead power line guarantees power supply safety, and the earth electrode that is embedded in ground usually is connected with overhead line structures through bolt, guarantees the lightning rod on shaft tower top and the good conducting of the earth.And, be subjected to all multifactor influences of outdoor environment with the increase of the circuit operation time limit, and corrosion can take place in earth electrode and shaft tower connecting bolt, and earth electrode also can the displacement relatively downwards with the sinking on ground, thus causing connecting becomes flexible, and influences effective work of earth electrode.Therefore, the periodic inspection of earth electrode connecting bolt being changed, is the important measures that guarantee the power circuit safe operation.Change in the operation in the earth electrode maintenance, the problem that to be the earth electrode that causes owing to earth electrode displacement downwards misplace with shaft tower connecting bolt hole that often runs into, at present in upkeep operation, the method of adjusting the dislocation of connecting bolt hole is that manpower upwards lifts earth electrode, perhaps use steel wire rope to become to lift instrument, be used for upwards promoting of earth electrode with the crowbar occasional combination.Owing to there not be the earth electrode lifting instrument that is suitable for, the upkeep operation of earth electrode is wasted time and energy, labour intensity is big, inefficiency, and be difficult to guarantee the safety and the quality of service work.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of earth electrode lifter that is applicable to the earth electrode maintenance is provided, and with the labour intensity of effective reduction earth electrode upkeep operation, increases work efficiency, and guarantees the safety and the quality of earth electrode service work.
The technical scheme that realizes above-mentioned purpose is: a kind of earth electrode lifter, it has the steel wire rope that is assemblied on the U-shaped pedestal and twines axle, its two ends of twining axle are given prominence to and are disposed respectively anti-revolution ratchet and are connected spindle nose with handle by the both sides panel of U-shaped pedestal, match with ratchet and to be provided with mounted elastically ratchet, fag end end at steel wire rope is provided with butt hook, below the bottom panel of U-shaped pedestal, be hinged and be connected to the U-shaped connector, be provided with the connection transverse axis in the bottom of connector, hinge is connected to transverse axis and is provided with the lifting hook.
When the utility model uses, steel wire rope on utilization places and butt hook twine on the online bar or are hooked on the line tower angle steel, utilization places the lifting of lower end to hook the connecting plate of earth electrode upper end, use the dedicated handle or the common wrench of configuration to rotate the winding axle, can finish the lifting of earth electrode.In promoting operating process, twine the ratchet of axle head and cooperating of mounted elastically ratchet by being fixed in, can prevent that the winding axle after the lay winding wire ropes from turning round.Discharge ratchet and move ratchet, the winding axle is turned round as required.The utility model is simple in structure, and is easy to use, can effectively alleviate the labour intensity of earth electrode upkeep operation, increases work efficiency, and guarantees the safety and the quality of service work.
