Supporter is played a supporting role; Extension type horizon bar length can adjust, and has good insulation property and mechanical strength, can meet the work of various electric pressure power line tension shaft tower level installing earth connection; Fixed muffle plays connection function; Steel wire rope is used for connecting installing earth connection fixture, is placed on power transmission line, completes the overlap joint of ground wire to facilitate by wire clamp.
Described supporter comprises fastening backplate, arranges wing screw A bottom fastening backplate, top mounting bracket, cradle top installs roating sphere by securing member, roating sphere top arranges fastening bracket, installs pulley between the side plate of fastening bracket, and extension type horizon bar is placed on pulley.Fastening backplate is fixed on cross arm of tower by wing screw A, and the angle of fastening bracket can be adjusted by roating sphere and securing member, thus the angle of adjustable extension type horizon bar; Fastening bracket plays the protective effect preventing extension type horizon bar from deviating from; Link effect is articulated in by annealed copper wire on extension type horizon bar, effectively prevents annealed copper wire from waving and reducing labor intensity.
Securing member between described support and roating sphere is wing screw B, and the outer end of installing earth connection fixture arranges electrical verification pole, and annealed copper wire arranges link.Electrical verification pole can detection line whether with residual voltage, ensure safety.
Described wire clamp comprises two fixture blocks be hinged by connecting plate, the two ends of steel wire rope are respectively by between the top being bolted to two fixture blocks, between the bolt of both sides and corresponding connecting plate, wire clamp spring is set respectively, run through between two bottom, fixture block hinged places and support pin is set, support pin one end and arrange wave shape groove, corresponding wave shape groove arranges the projection matched in the fixture block of corresponding end.Wire clamp is the part be directly connected with wire, and the wire clamp of this structure reduces labor intensity effectively carrying out mounting, when retracting, convenient operation; Support pin and run through two fixture blocks settings, the projection that the corresponding wave shape groove supporting pin matches in fixture block, to realize supporting the function that pin supports two fixture blocks and stressed rear disengaging fixture block.
Operation principle and process:
The present invention mainly adopts lever principle, extension type levels operation bar is placed on pulley, two fixture blocks of conductor wire end wire clamp open and use and support pin support, make it automatically to close, again installing earth connection fixture is through on steel wire rope, by adjusting the position of roating sphere, wire clamp can reach above the wire of strain insulator string front end by maintainer on cross arm of tower, by handling extension type horizon bar, transfer wire clamp, when supporting pin and touching wire, conductor wire end wire clamp can be automatically closed, wire is clamped, thus complete the mounting work of earth connection.In like manner, when retracting wire clamp, installing earth connection fixture applies power upwards to steel wire rope, and steel wire rope to wire clamp generation effect, impels wire clamp to open simultaneously, can complete the dismounting work of earth connection.
The invention has the beneficial effects as follows:
By changing original artificial line-outgoing type installing earth connection method into carry out remote horizontal installing earth connection on electric power line pole tower cross-arm method, effectively can ensure the personal safety of operating personnel, reduce labour intensity, increase work efficiency, simple to operation; The installation of suitable various electric pressure strain rod tower earth connection.
