Abstract
The utility model relates to an insulting operation bar with a grounding line. The insulting operation bar is composed of three segments of insulating rubber bars. Aluminium connecters are arranged at the joints of the insulating rubber bars. A rubber umbrella is arranged at the upper end of the aluminium connecter close to an operation head of the insulting operation bar, and the aluminium connecter at the lower part of the insulting operation bar is provided with a metal hook which is connected with the grounding line. According to the utility model, the body of the insulting operation bar is divided into three segments, and provided with the aluminium connecters at the joints, and the rubber umbrella is arranged at the connecter close to the operation head of the insulting operation bar to ensure the lower two insulating rubber bars to keep dry, so that dew and rain are effectively prevented from flowing along the insulating rubber bars in extreme weather, and the safety coefficient of the insulting operation bar is greatly increased; the connecter close to a handling end of the insulting operation bar is provided with the hook which is connected with the grounding line, so that weak current that might be generated is guided to the ground by the grounding line, thereby protecting the safety of the operator holding the handling end; besides, the insulting operation bar is simple in structure, effective in use, and low in production and use costs, having high popularization and application values.
Description
Technical field
The utility model relates to a kind of electric power system renewal part equipment, is specifically related to a kind of zero gram rod of line with ground.
Background technology
Electric power system is at present changed zero gram and is conventionally used zero gram rod, and because a zero gram filament length phase was exposed under external environment condition, the factors such as impressed current overload of exposing to the sun and rain, are easier to fracture, and the work of therefore changing crane with zero gram of rod is very frequent.During due to replacing crane, zero gram of rod contact be high-tension electricity, therefore in crane Renewal process, guarantee that being perfectly safe of operator is necessary, but our zero gram rod used is mostly relatively simple for structure at present, there is no ground connection, design such as rainproof grade, when running into greasy weather or the special wet weather of air, zero gram excellent coefficient of safety will be in various degree reduction, add in zero gram of excellent school inspection, occur sometimes undetected, the situation of exceeding the time limit etc., and change and in crane process, to be prone to the factors such as manual operation is improper, cause changing crane work and have larger potential hazard.How to guarantee that zero gram rod is applicable to extreme weather and guarantees that being perfectly safe of operator is the problem demanding prompt solution facing during current crane more changes jobs.
Summary of the invention
Technical problem to be solved in the utility model; be exactly for the existing deficiency of above prior art; and a kind of zero gram rod of line with ground proposed; this zero gram rod is divided into three sections by barred body; junction is provided with aluminum joint; joint is provided with rubber umbrella and earth connection; effectively prevent that under extreme weather, dew, rainwater etc. flow along electro-insulating rubber bar; improved zero gram excellent coefficient of safety; the weak current that earth connection may occur imports the earth; adequately protect operating personnel's the fail safe of hand-held end, has good application value.
The utility model scheme is achieved by the following technical measures:
A kind of zero gram rod of line with ground, its feature is that this zero gram barred body is connected by three sections of electro-insulating rubber bars, electro-insulating rubber bar junction is provided with aluminum joint, and the aluminum upper end of joint of close zero gram excellent working head is provided with rubber umbrella, and the aluminum joint of lower end is provided with earth connection.
The aluminum joint of above-described zero gram barred body upper and lower side is provided with metal hanger, earth connection coupling hook.
The beneficial effects of the utility model are:
This zero gram rod is divided into three sections by barred body, junction is provided with aluminum joint, joint near zero gram excellent working head is provided with rubber umbrella, can guarantee that two sections of electro-insulating rubber bars keep dry below, effectively prevent that under extreme weather, dew, rainwater etc. flow along electro-insulating rubber bar, greatly improved zero gram excellent coefficient of safety; Zero gram rod is provided with and buckles near the joint of handheld terminal, is connected the weak current importing the earth that earth connection may occur, the operating personnel's of the hand-held end that adequately protects fail safe with earth connection.This zero gram bar structure is comparatively simple in addition, and result of use is better, and production and use cost are lower, have good application value.
Accompanying drawing explanation
Fig. 1 is zero gram excellent structural representation of a kind of line with ground described in the utility model, in figure, 1 be wherein electro-insulating rubber bar, and 2 is aluminum joint, and 3 is rubber umbrella, and 4 is earth connection, and 5 is zero gram excellent working head, and 6 is metal hanger.
Embodiment
In order to make the technical solution of the utility model clearer, below in conjunction with accompanying drawing, 1 use embodiment is further described the utility model.
As shown in Figure 1, a zero gram rod of line with ground, its feature is that this zero gram barred body is connected by three sections of electro-insulating rubber bars 1, electro-insulating rubber bar 1 junction is provided with aluminum joint 2, aluminum upper end of joint near zero gram excellent working head 5 is provided with rubber umbrella 3, and the aluminum joint of lower end is provided with earth connection 4.
The aluminum joint of above-described zero gram barred body upper and lower side is provided with metal hanger 6, earth connection 4 connection metal hooks 6.
During use, by earth connection 4 ground connection, the joint of close zero gram excellent working head 5 is provided with rubber umbrella 3, can guarantee that two sections of electro-insulating rubber bars 1 keep dry below, effectively prevent that under extreme weather, dew, rainwater etc. flow along electro-insulating rubber bar 1, greatly improved zero gram excellent coefficient of safety; Zero gram rod is provided with metal near the joint of handheld terminal and buckles 6, is connected the weak current importing the earth that earth connection 4 may occur, the operating personnel's of the hand-held end that adequately protected fail safe with earth connection 4.
