Abstract

The utility model relates to a ground wire apparatus, particularly to a ground wire apparatus for power-failure maintenance of an overhead transmission line. A middle portion of an upper fixed hook is fixed at the upper end of an insulated rod (9). One bending end of the upper fixed hook is hinged to an upward bending end arranged at one side of a lower movable hook (4) by a shaft; a long circular hole (5) formed in the middle portion of the lower movable hook is sleeved at the upper portion of the insulated rod; and the other bending end of the upper fixed hook is located at the middle portion between an upward bending end at the other side of the lower movable hook and the insulated rod. An upper end and a lower end of a spring (6) sleeved at the upper portion of the insulated rod are respectively pressed against the lower portion of the lower movable hook and a baffle ring arranged at the insulated rod; and one end of a ground wire (7) is connected to the lower movable hook. According to the scheme, the upper fixed hook and the lower movable hook are arranged to be in a movable holding-on structure, so that ground demand of a lead, a wiring terminal, or a plate-shaped structure can be satisfied and thus an objective of multiple purposes integration to one object can be achieved.

Description

A kind of overhead transmission line maintenance grounding wire device in the time having a power failure

[technical field]

The utility model relates to a kind of grounding wire device, especially relates to a kind of overhead transmission line maintenance grounding wire device in the time having a power failure.

[background technology]

Known, in overhead transmission line has a power failure maintenance or in repairing wire maintenance process, for preventing that electric shock accidents occurs incoming call suddenly, between circuit and bottom surface, need to arrange earth connection, existing earthing clamp accommodates end and is mostly hook-type structure, and a fixing hook is namely set on action bars top, in the time of connecting band electric lead, need vertical use, but can not be general during for overhaul of the equipments, be equipped with multiple earth connection so cause, carry very inconvenient.

[summary of the invention]

In order to overcome the deficiency in background technology, the purpose of this utility model is to provide a kind of overhead transmission line maintenance grounding wire device in the time having a power failure, be set to movable occlusion structure by upper stay hook, lower movable hook, can adapt to the ground connection needs of wire, binding post or platy structure, realize the object of one-object-many-purposes.

For achieving the above object, the utility model adopts following technical scheme:

A kind of overhead transmission line maintenance grounding wire device in the time having a power failure, comprise handle, insulating bar, upper stay hook, lower movable hook, spring and earth connection, the lower end of insulating bar is provided with handle, upper stay hook middle part is screwed in the upper end of insulating bar, upper stay hook both sides are respectively equipped with bending end down, one of them bending end of upper stay hook is by the be articulated and connected bending end upward of lower movable hook one side of axle, the slotted hole that lower movable hook middle part arranges is enclosed within the top of insulating bar, another bending end of upper stay hook is in the lower movable hook opposite side middle part between bending end and insulating bar upward, the upper and lower two ends of spring that are enclosed within insulating bar top withstand on respectively on the baffle ring on bottom and the insulating bar of lower movable hook, earth connection 7 one end are connected on lower movable hook.

Owing to adopting technical scheme as above, the utlity model has following superiority:

Overhead transmission line described in the utility model is maintenance grounding wire device in the time having a power failure, and by the occlusion structure that upper stay hook, lower movable hook are formed by spring, can adapt to the ground connection needs of wire, binding post or platy structure; The utility model is rational in infrastructure, has realized the object of one-object-many-purposes, is beneficial to and applies.

[brief description of the drawings]

Fig. 1 is perspective view of the present utility model;

In the drawings: 1, screw; 2, upper stay hook; 3, axle; 4, lower movable hook; 5, slotted hole; 6, spring; 7, earth connection; 8, extend hook; 9, insulating bar; 10, handle.

[embodiment]

By reference to the accompanying drawings to the utility model further instruction; The utility model is not limited to the following examples;

Overhead transmission line described in 1 maintenance grounding wire device in the time having a power failure by reference to the accompanying drawings, comprise handle 10, insulating bar 9, upper stay hook 2, lower movable hook 4, spring 6 and earth connection 7, the lower end of insulating bar 9 is provided with handle 10, upper stay hook 2 middle parts are fixed on the upper end of insulating bar 9 by screw 1, upper stay hook 2 both sides are respectively equipped with bending end down, one of them bending end of upper stay hook 2 is by the be articulated and connected bending end upward of lower movable hook 4 one sides of axle 3, the slotted hole 5 that lower movable hook 4 middle parts arrange is enclosed within the top of insulating bar 9, another bending end of upper stay hook 2 is in the lower movable hook 4 opposite sides middle part between bending end and insulating bar 9 upward, the spring that is enclosed within insulating bar 9 tops withstands on respectively on the baffle ring on bottom and the insulating bar 9 of lower movable hook 4 at two ends Shang Xia 6, earth connection 7 one end are connected on lower movable hook 4.

Implement overhead transmission line described in the utility model maintenance grounding wire device in the time having a power failure, when use, the extension hook 8 that hand-held handle 10 forms lower movable hook 4 opposite sides upward, be placed on transmission line bottom, upper pushing handle 10 the slip the utility model of taking advantage of a situation, just can be stuck in transmission line in another bending end of upper stay hook 2; Upper pushing handle 10 while taking off the utility model, transmission line just can take off the utility model in extending hook 8 inner sides.

The utility model does not describe part in detail for prior art.

The embodiment selecting in this article for open the purpose of this utility model, current think suitable, but will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the embodiment within the scope of this design and the utility model.
