Description
Technical field
The utility model relates to a kind of power matching network live line work insulating socket bar.
Background technology
Insulating sleeve bar is electric power system operating personnel widely used a kind of important jointer in distribution network live line work, and for example, in lead-in wire overlap joint, operating personnel usually adopts insulating sleeve bar to tighten parallel groove clamp, thereby difference lead-in wire is overlapped on main line.Existing insulating sleeve bar is comprised of upper boom and two poles of lower beam of column conventionally, approximately 3.3 meters of total lengths, upper boom comprises sleeve, connector and shaft from top to bottom, the top of sleeve is embedded with the counterbore (sleeve size is optional) of receiving hex bolts, and the bottom of upper boom is provided with the connection-peg being connected with lower beam.Lower beam comprises tapered end, shaft and rocking handle from top to bottom, and tapered end is responsible for docking with upper boom connection-peg, realizes firmly and connecting.During operation, first upper boom and lower beam are linked to be to integral body, and keep vertical shape, the top counterbore of upper boom is inserted on the bolt of the parallel groove clamp that is positioned at top, and then, operating personnel grip the bottom of lower beam on the other hand, another hand rotation crank, rotation by upper boom and lower club body, screws bolt, thereby difference lead-in wire is overlapped on main line.
Before the utility model is made, there are the following problems for this insulating sleeve bar:
1, effort, operating difficulties.
Operating personnel are in live line working, need on hand to wear under the situation of three gloves (lining glove, insulating gloves, kid gloves), the insulating bar afterbody that only relies on single the long 3.3M of left-handed, another hand removes to rotate the rocking handle of this socket bar again, and difficulty is well imagined.In operation process, it is vertical that left hand (hereinafter to be referred as gripping hand) should firmly maintain socket bar, prevent from or fall down, hang on to again the mellow and full socket bar of smooth surface and upwards exert oneself, prevent that it from deviating from from bolt, another hand must rotation crank, and two hands are all suspended in the air, operating difficulties, effort.
2, wire is fixing not in place, has potential safety hazard.
During due to operation, socket bar need to rotate along with rocking handle, therefore exist rocking handle to rotate and grip hand in good time loose this to contradiction, in reality, this contradiction usually causes the arc clip on parallel groove clamp to occur deviation phenomenon, make wire clamp fixing cord not in place, and have potential safety hazard.
3, partly upwards top power and rocking handle rotatory force are cancelled out each other, and efficiency is low.
During due to operation, socket bar needs larger top power to withstand Bing ditch wire clamp on the one hand, and the grip of the larger gripping hand of top power is larger, and the larger socket bar of grip is held more fastening; Socket bar is again along with rocking handle rotates and rotate on the other hand, and it is in good time loose that rotation crank need to grip hand.In brief, grip the hand-tight socket bar of holding, right hand rotational sleeve bar, just a positive and a negative, the mutually opposing of this group active force.Certainly will cause gripping the hand portion phenomenon that the rocking handle rotatory force of top power and the right hand cancels out each other that makes progress, and greatly reduce operating efficiency.
Summary of the invention
For solving the problems of the technologies described above, the utility model aims to provide a kind of distribution network live line work insulating sleeve bar, and that this socket bar has is easy to operate, time saving and energy saving, the fastening advantage such as put in place of wire.
For achieving the above object, the utility model has adopted following technical proposals, the structure of this distribution network live line work insulating sleeve bar, comprise lower beam and rocking handle, it is characterized in that: the upper end of the bottom of described shaft and a core bar is fixedly connected, described core bar is arranged in the gripping pipe that a upper port is fixed with flange, has the bearing in a circle radial convex loop limit, inner chamber with fixing described core bar on this flange shell; The lower end of this core bar and described rocking handle are fixed together.During operation, operating personnel's one clenching of the hand grips pipe, another hand rotation crank, and rocking handle drives lower club body through core bar, and upper boom rotation, completes the rotation to parallel groove clamp fastening bolt; Utilize this socket bar lap works that goes between, owing to gripping pipe, do not need to follow rocking handle and rotate, therefore do not have rocking handle to rotate, grip hand loose and say.Moreover, use the power that gripping hand tiger's jaw and flange convex ring edge offset, make to maintain all the time the top power making progress and become especially convenient, reliable, guarantee that deviation phenomenon does not occur arc clip.
Furtherly, two of the upper ends level of described core bar is fixed together to bearing pin and the lower beam settled.
Beneficial effect: compared with prior art, the utility model is set up the gripping pipe that need to not rotate with rocking handle owing to having adopted in lower beam bottom, and be fixedly nested with after the flange with radial convex loop limit in gripping pipe upper port, overcome present technology socket bar rocking handle rotate and grip hand in good time loose this to contradiction, make operating difficulties effort, wire that original insulating sleeve bar exists always fixing not in place, there is potential safety hazard, and part upwards top power cancel out each other with rocking handle rotatory force, the low grade of efficiency series of problems is readily solved.
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.Clear for illustrating, in figure, be drawn into the stereochemical structure of parallel groove clamp.
