Abstract
The utility model discloses an earth electrode, comprising a supporting frame having an open-ended side. The supporting frame is clamped and mounted on an iron tower and made of conductive materials. The end surface of the supporting frame is provided with binding posts for connecting an earth wire. The supporting frame is inwardly provided with a pressing plate adjusted by a screw rod and used for pressing against the iron tower. The screw rod extends out of the supporting frame. The side of the screw rod, extending out of the supporting frame, is provided with a handle fixedly connected with the screw rod. The side of the pressing plate, opposite to the open-ended side of the supporting frame, is provided with a slide chute. A slide rail matching with the slide chute is arranged at a corresponding position inside the supporting frame. The pressing plate is provided with an unthreaded hole corresponding to the screw rod. The side surface of the unthreaded hole on the pressing plate is provided with a screwed hole perpendicularly communicated with the unthreaded hole. The tail end of the screw rod is provided with an unthreaded rod corresponding to the depth of the unthreaded hole. The earth electrode is characterized by being simple in structure, reasonable in design, beautiful in form, and convenient to hang, and is capable of effectively reducing the working burden of working personnel.
Description
Technical field
The utility model relates to a kind of electric power operation device, specifically a kind of earth electrode of the tower line for needing ground connection.
Background technology
Along with developing rapidly of China's economic construction, the demand of electric power is sharply increased various places also erect power transmission lines in a large number steel tower or shaft tower.In 110kV line construction and the construction of part steel tower, the wire distance to the ground is far away, causes the staff to promote ground wire difficulty and waste material.
The utility model content
The utility model technical issues that need to address provide a kind of earth electrode for the tower line that needs ground connection of safe ready.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Earth electrode, the carriage that the conductive material on the steel tower is made that is installed on that comprises a side opening, be provided for connecting the binding post of ground wire on the end face of carriage, the inner pressure strip that is used for propping up steel tower of being regulated by screw rod that arranges of carriage, described screw rod stretches out outside the carriage, and screw rod stretches out the handle that a side setting of carriage is fixedly connected with screw rod.
Further improvement of the utility model is: the side that described pressure strip is relative with the carriage openend arranges chute, the slide rail that the correspondence position setting of carriage inside cooperates with chute.
Further improvement of the utility model is: the unthreaded hole corresponding with screw rod is set on the described pressure strip, on the pressure strip setting of the side of unthreaded hole and unthreaded hole vertical communicate screwed hole, the end of screw rod arranges one section polished rod corresponding with the degree of depth of unthreaded hole.
Further improvement of the utility model is: the bottom surface that described pressure strip contacts with steel tower arranges anti-skidding striped.
Further improvement of the utility model is: the inner one side relative with screw rod of described carriage is provided with the groove that the cross section is arc.
Further improvement of the utility model is: described binding post is two, and binding post is arranged on the end face with the relative side of the openend of carriage.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The earth electrode of the utility model design, can by pressure strip and screw rod with carriage fastening with steel tower on, ground wire just can be connected on the binding post of carriage, use during for the circuit that needs ground connection or shaft tower construction, saved the earth connection material, alleviated again staff's lodge ground wire work load, the convenient use.Described pressure strip is stuck in the slide rail of carriage, makes things convenient for the staff to operate, and pressure strip also is not easy landing.The screw rod tip designs is become polished rod with threaded hole, be more conducive to being fastenedly connected of pressure strip.In the pressure strip bottom anti-skidding striped is set, prevents the relative sliding of pressure strip and steel tower.The arc groove of carriage setting also is convenient to be connected to the positions such as round bar.The utlity model has simple in structure, reasonable in design, form is attractive in appearance, make things convenient for the characteristics of hanging ground-wire, has effectively alleviated staff's work load.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
Earth electrode as shown in Figure 1, comprises carriage 4, screw rod 2, pressure strip 3.One side opening of described carriage 4 is used for being installed on steel tower, can be the shape of similar channel-section steel.Carriage 4 selects conductive material to make.Two binding posts 5 that are used for connecting ground wire are set on the end face of the side that the openend of carriage 4 is relative.Carriage 4 inside arrange pressure strip 3, and the top connecting screw rod 2 of pressure strip 3 is used for propping up steel tower by what screw rod 2 was regulated pressure strips 3.Screw rod 2 stretches out outside the carriage 4, and screw rod 2 stretches out the handle 1 that a side setting of carriage 4 is fixedly connected with screw rod.The side that described pressure strip 3 is relative with carriage 4 openends arranges chute, the slide rail 8 that the correspondence position setting of carriage 4 inside cooperates with chute.The unthreaded hole corresponding with the thickness of screw rod 2 is set on the described pressure strip 3, and the side of unthreaded hole arranges vertical with unthreaded hole and a communicate screwed hole on the pressure strip.The end of screw rod 2 arranges one section polished rod consistent with the degree of depth of unthreaded hole.When pressure strip 3 slides into when contacting with steel tower along slide rail, firmly pin pressure strip 3, the polished rod of screw rod 2 is partly stretched in the unthreaded hole of pressure strip, the bolt 7 of then screwing in the screwed hole on pressure strip 3 is in order to fix screw rod.The relative position relation that other connections prevent from keeping pressure strip 3 and screw rod 2 also can be set, for example at pressure strip 3 threaded blind hole is set, and screw rod 2 be forms of full thread.The bottom surface that described pressure strip 3 contacts with steel tower arranges anti-skidding striped.The inner one side relative with screw rod 2 of carriage 4 namely is provided with the groove 6 that the cross section is arc on the face of the carriage relative with the bottom surface of pressure strip, the steel tower use of more convenient and round bar.
