Description
Technical field
Aid while the present invention relates to power construction, specifically a kind of mechanism that has simultaneously electrical verification and back brake function.
Background technology
Along with industrial expansion, all trades and professions improve day by day to the power supply reliability of electric power system and the requirement of stability, therefore power system operation are safeguarded and are overhauled particularly important.In electric power system during console switch, after running into sometimes the switch operating rod action, indicating device also arrives a minute position, but internal mechanism goes wrong separately unactual, caused the situation of on-load broaching tool lock to occur, there is larger potential safety hazard in this, therefore, after cut-off switch, the staff is usually to just carrying out back brake after the load side electrical verification.Existing general electroscope length is shorter, the switching manipulation personnel must step on bar to switch place in the time of will be to the load side electrical verification and carry out electrical verification, after identifying with no pressure, the switching manipulation personnel drop to certain altitude again, by the ground handling personnel, link rod is passed to operating personnel on bar and carry out grid switching operation, operating efficiency is low, and the switching manipulation personnel step on bar operation and have potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of mechanism that has simultaneously electrical verification and back brake function is provided, simple operation during its application, and can avoid operating personnel to step on the existing potential safety hazard of bar operation.
purpose of the present invention is achieved through the following technical solutions: a kind of mechanism that has simultaneously electrical verification and back brake function, comprise the link rod working head, electrical verification head and extensible member, described extensible member comprises bottom sleeve, extension and backstay, described extension lower end is connected with the first positioning threads head, the first positioning threads head is connected with the bottom sleeve upper end by the mode that screw thread mates, described backstay lower end is connected with the second positioning threads head, the second positioning threads head is connected with the extension upper end by the mode that screw thread mates, described backstay top indent forms positioning screw hole, described link rod working head and electrical verification head lower end all are connected with positioning screw, positioning screw is provided with the external screw thread with positioning screw hole internal thread coupling.In order to guarantee operating personnel's safety, in the present invention, all parts adopt insulation materials to make, or at the plated surface insulating varnish of all parts.When the present invention applies, if need the load side electrical verification be embedded the positioning screw of electrical verification head in positioning screw hole, if need carry out grid switching operation, the positioning screw of link rod working head is embedded in positioning screw hole.
The external diameter of described extension is less than the internal diameter of bottom sleeve, and the diameter of described backstay is less than the internal diameter of extension.The present invention is by penetrating backstay when mounting design from the extension lower end, the backstay upper end passes from the extension upper end, and extension penetrates from the bottom sleeve lower end, and the extension upper end passes from the bottom sleeve lower end.When the present invention does not use, can with bottom sleeve, break away from and be connected by making the first positioning threads head, and the second positioning threads head is broken away from and is connected with extension, so, extension is placed in bottom sleeve, and backstay is placed in extension, and it is convenient when the present invention is not used, to carry.
While for fear of the present invention, using, extension and backstay do not break away from bottom sleeve, and described bottom sleeve lower end is provided with the bottom head that embeds in it, and described bottom head and bottom sleeve form interference fit.
As preferably, described bottom sleeve, extension and backstay three's length is 1.5m.
When the present invention applied, operating personnel held bottom sleeve and operate, and occurred skidding while for operating personnel, holding bottom sleeve, on described bottom sleeve, were arranged with the Anti-slip cover with its interference fit.
In order to strengthen the non-skid property of Anti-slip cover, described Anti-slip cover outer wall forms a plurality of granular projections.
Occur skidding when further avoiding operating personnel to hold bottom sleeve, on described bottom sleeve, also be arranged with two spacing rings with its interference fit, described Anti-slip cover is between two spacing rings.
compared with prior art, the present invention has following beneficial effect: the present invention includes the link rod working head, electrical verification head and extensible member, wherein, extensible member comprises bottom sleeve, extension and backstay, the extension lower end is connected with the first positioning threads head, the first positioning threads head is connected with the bottom sleeve upper end by the mode that screw thread mates, the backstay lower end is connected with the second positioning threads head, the second positioning threads head is connected with the extension upper end by the mode that screw thread mates, backstay top indent forms positioning screw hole, link rod working head and electrical verification head lower end all are connected with positioning screw, positioning screw is provided with the external screw thread with positioning screw hole internal thread coupling, the present invention adopts said structure, overall structure is simple, be convenient to realize, cost is low, in the present invention, extensible member is mainly by bottom sleeve, extension and backstay three parts form, extension all is connected by the mode that screw thread mates with backstay with bottom sleeve, dismounting is convenient, be convenient to management, the present invention can be by guaranteeing the length of extensible member after splicing, during to the load side electrical verification, the positioning screw of electrical verification head is embedded in positioning screw hole, operating personnel hold bottom sleeve can carry out the electrical verification operation, if need carry out grid switching operation, the electrical verification head is disassembled from extensible member, again the positioning screw of link rod working head is embedded in positioning screw hole, operating personnel hold bottom sleeve can carry out grid switching operation, simple operation, in the length assurance situation of extensible member, electrical verification and back brake all can carry out on ground, so, can eliminate the potential safety hazard that operating personnel step on the bar operation.
