In order to the equipment end jaws overcoming existing angle mode crane type earth rod can not carry out the deficiency of bidirectional modulation, heavier-weight, the invention provides a kind of can bidirectional modulation stationarity is good, easy to operate, operating efficiency is higher bi-directional movable gear angle mode crane type earth rod.
The technical solution adopted for the present invention to solve the technical problems is:
Bi-directional movable gear angle mode crane type earth rod, comprise insulated handle, be arranged on the spiral ejection pin of described insulated handle end and be arranged on the equipment end holder at described spiral ejection pin top, described equipment end holder is provided with grounding end connector, described grounding end connector is connected with earth connection, described equipment end holder comprises clamping part and lower clamping part, the equipment end jaws in order to holding electrical equipment is formed between described upper clamping part and described lower clamping part, the rear end of described upper clamping part is cemented on pedestal, the rear end of described lower clamping part is hinged on described pedestal, the lower hinge of described pedestal has push rod external member, described spiral ejection pin contacts in the bottom of described lower clamping part through described push rod external member, the bottom of described lower clamping part is provided with tooth-shape structure, the external screw thread of described spiral ejection pin upper end matches with described tooth-shape structure, spring is provided with between described upper clamping part and described lower clamping part, the upper end of described spring contacts the postmedian of clamping part on described, the lower end of described spring contacts at the pin joint of described lower clamping part and described pedestal with between described lower clamping part and the contact point of described spiral ejection pin.
Further, the front end of described upper clamping part is provided with activity template, and the front end of described lower clamping part is provided with lower activity template, between described upper activity template with described upper clamping part, is torsion spring is connected between described lower activity template with described lower clamping part.
Further again, described upper activity template is provided with tooth-shape structure in the side near described lower activity template.
Further again, described insulated handle is dismountable to be arranged in described push rod external member.
Further again, described upper activity template and described lower activity template are petal-shaped, and described upper activity template and described lower activity template are arranged symmetrically on described equipment end holder.
Further, the material of described equipment end holder is aluminium dilval.
Beneficial effect of the present invention is mainly manifested in:
1, because the insulated handle of the operated earth connection of angle adjustable can take off, only need an insulated handle can complete operation, each transformer station only need be equipped with two insulated handles, and wherein one is for subsequent use, so just, a large amount of insulated handles can be saved, save manufacturing cost;
2, shorten the time installation of earth connection, improve operating efficiency;
3, equipment end hold assembly adopts two-way adjustable angle, can solve real work earthing position and does not fix and bring asking of difficulty to carry to operation;
4, equipment end hold assembly adopts tooth-shape structure to fix, and arbitrarily can not rock, improve fail safe.
