Technical field
The utility model relates to a kind of power equipment Work tool, particularly relates to a kind of outdoor voltage levels converting equipment test operation bar.
Background technology
In 110kV and above transformer station, voltage levels circuit breaker is installed, current transformer, voltage transformer, transformer, lightning arrester and isolating switch, numerous converting equipments such as grounding switch, these voltage levels converting equipments are arranged on the overhead eminence of 3-5 rice conventionally, for completing these voltage levels converting equipment electrical test wiring, the work of taking out stitches, staff need to carry out ascend operation by means of high-altitude operation vehicle, ascend a height up and down respectively once for completing a phase power transformation testing of equipment need of work, the time of ascending a height occupies 80 percent left and right of single test time up and down.For preventing that high-altitude operation vehicle from breaking converting equipment or mistake forward (FWD) electricity interval, the common service speed of high-altitude operation vehicle is slow, complete upper and lower ascend operation and need to expend the plenty of time, cause current outdoor voltage levels converting equipment electric test operating efficiency low, and also there is the danger of falling from high altitude in ascend operation.Therefore, development is a kind of without ascend operation, can test wiring, the work of taking out stitches by the outdoor voltage levels converting equipment of portable realization on ground, contribute to the outdoor voltage levels converting equipment test operating arm dedicated of increasing work efficiency and ensuring personal safety to there is very important engineering practical value.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of without ascend operation, can test wiring, the work of taking out stitches by the outdoor voltage levels converting equipment of portable realization on ground, contribute to the outdoor voltage levels converting equipment test operation bar of increasing work efficiency and ensuring personal safety.The utility model solves the technical scheme that its technical problem adopts:
A kind of outdoor voltage levels converting equipment test operation bar, comprise jointing clamp, insulation stock, connecting ring, pull rope, middleware and extension device, described jointing clamp comprises movable tong arm, fixing tong arm, jointed shaft and return mechanism, the middle part of this activity tong arm is hinged by the middle part of this jointed shaft and this fixing tong arm, one end of this activity tong arm and one end of this fixing tong arm form the jaw of this jointing clamp, thereby this activity tong arm can rotate and open or closed this jaw around this jointed shaft, this return mechanism applies closed this jaw of elastic force to this activity tong arm, this fixing tong arm lower end is provided with junction button, the end of this insulation stock is provided with the joint being interlockingly connected with this junction button, the other end Joint of this middleware one end and this activity tong arm, one end Joint of this middleware other end and this extension device, this connecting ring is connected to the below of this extension device the other end setting near this extension device, this pull rope one end tying-up is on this connecting ring.
The technical program is compared with background technology, and its tool has the following advantages:
When on-the-spot use, test wire is connected on extension device with crocodile clip geometrical clamp, lift insulation stock, the drop-down pull rope other end of exerting oneself, open described jaw, put outdoor voltage levels converting equipment wire clamp into described jaw inside, unclamp pull rope, closed this jaw again under this return mechanism effect.The utility model is simple in structure, and operation is used easily, without ascend operation, can test wiring, the work of taking out stitches by the outdoor voltage levels converting equipment of portable realization on ground, contributes to increase work efficiency and ensure personal safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the schematic diagram of the outdoor voltage levels converting equipment of the utility model test operation bar.
Embodiment

Described jointing clamp 10 comprises movable tong arm 11, fixing tong arm 12, jointed shaft 13 and return mechanism 14.The middle part of this activity tong arm 11 is hinged by this jointed shaft 13 and the middle part of this fixing tong arm 12, and one end of one end of this activity tong arm 10 and this fixing tong arm 12 forms the jaw 15 of this jointing clamp 10.Thereby this activity tong arm 11 can rotate and open or closed this jaw 15 around this jointed shaft 13.Thereby this return mechanism 14 is for applying closed this jaw 15 of elastic force to this activity tong arm 11.These fixing tong arm 12 lower ends are provided with junction button 122.
The end of this insulation stock 20 is provided with the joint 22 being interlockingly connected with this junction button 122.
The other end Joint of these middleware 50 one end and this activity tong arm 11.One end Joint of these middleware 50 other ends and this extension device 60.This connecting ring 30 is connected to the below of this extension device 60 other end setting near this extension device 60.These pull rope 40 one end tying-ups are on this connecting ring 30.
Described pull rope 40 and insulation stock 20 are made for insulating material.
Described middleware 50, extension device 60, movable tong arm 11 and fixing tong arm 12 are all that metallic conduction material is made.
When normality, this return mechanism 14 is executed resilience active force to this activity tong arm 11 and is made this jaw 15 in stinging tight state.
When use, test wire is connected on extension device 60 with crocodile clip geometrical clamp, lift insulation stock 20, the drop-down pull rope 40 of exerting oneself, in pull rope 4 downdraw process, drive activity tong arm 11 clockwise rotates around jointed shaft 13, opens jaw 15, puts outdoor voltage levels converting equipment wire clamp into jaw 15 inside, unclamp pull rope 40, act on lower clamp nozzle 15 at return mechanism 14 and again sting tightly.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
