Abstract
The utility model discloses a spiral earth connection appurtenance, including being cylindric clamp 1 of keeping silent, this clamp 1 lateral part of keeping silent is equipped with along the earth connection opening that length extends, and clamp 1 front end opening of keeping silent, its middle part rather than being equipped with butterfly fastening screw 2 perpendicularly, and this butterfly fastening screw 2 stretches into in the cavity of keeping silent 1 of keeping silent, and the threaded sleeve is equipped with two fixation nut 3 on the butterfly fastening screw 2, presss from both sides 1 rear end fixedly connected with collapsible hand pole 4 of keeping silent. Its simple structure, low cost, portable can effectively assist electric wire netting operating personnel to carry out the wiring work of spiral earth connection, and insulating gloves operation is convenient for wear by butterfly fastening screw, and operating personnel can screw up or the spiral earth connection of back-off fast according to clockwise, the anticlockwise rotation collapsible hand rod of needs of installing, demolising.
Description
Technical Field
This scheme relates to the earth connection and installs technical field, concretely relates to spiral earth connection appurtenance.
Background
In the field of power grids, 35kV, 10kV and 0.4kV grounding wires require that a spiral grounding wire must be used, a duckbill-type clamping grounding wire is not allowed to be used, and the operation of the spiral grounding wire is usually carried out under the condition of power failure. But the current spiral earth connection can only rely on the manual work to constantly rotate insulating handle and screw up the bolt in order to press from both sides tight wire. In actual operation, the current action bars that are used for the wiring is very smooth, and operating personnel wears under the insulating gloves condition, and the operation is very inconvenient, especially under the circumstances that the bolt corrosion card is dun, and operating personnel hardly twists out the bolt and carries out the earth connection operation, leads to hanging time long, wastes time and energy, influences the job schedule and delays the activity duration to cause the power off time to prolong greatly.
Therefore, it is necessary to design a tool which can facilitate the auxiliary operation of an operator on the spiral grounding wire, so that the operation difficulty is reduced, the mounting and dismounting operation time of the grounding wire is reduced, the power failure overhaul time can be reduced, and the power supply reliability of a power grid is improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the problem that present electric wire netting operating personnel dresses insulating gloves and are difficult for carrying out spiral earth connection operation, this application provides a spiral earth connection appurtenance.
The utility model adopts the following technical scheme:
the utility model provides a spiral earth connection appurtenance which the key lies in: including being cylindric clamp, should press from both sides the lateral part of keeping silent and be equipped with along the earth connection opening that length extends, press from both sides the front end opening of keeping silent, its middle part is equipped with butterfly fastening screw perpendicularly, and this butterfly fastening screw stretches into press from both sides in the cavity of keeping silent, threaded sleeve is equipped with two fixation nut on the butterfly fastening screw, press from both sides the collapsible hand pole of rear end fixedly connected with of keeping silent.
As the preferred scheme, collapsible rocker includes dead lever, connecting rod and rocker, the dead lever with press from both sides tight rear end axis vertical direction fixed connection of keeping silent, connect through the axis of rotation respectively between dead lever, connecting rod and the rocker.
Has the advantages that: the utility model discloses a spiral earth connection appurtenance, its simple structure, low cost, portable can effectively assist electric wire netting operating personnel to carry out the wiring work of spiral earth connection, and butterfly fastening screw is convenient for wear insulating gloves operation, and operating personnel can screw up or back loose spiral earth connection fast according to clockwise, the collapsible hand pole of anticlockwise rotation of needs of installing, demolising.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of foldable hand lever 4 in a folded state.
Detailed Description
The invention is described in further detail below with reference to the following figures and examples:
example (b): as shown in the attached drawing 1, the spiral type auxiliary tool for the ground wire comprises a cylindrical clamping jaw 1, wherein a ground wire opening extending along the length is formed in the side portion of the clamping jaw 1, the front end of the clamping jaw 1 is open, a butterfly-shaped fastening screw rod 2 is vertically arranged in the middle of the clamping jaw 1, the butterfly-shaped fastening screw rod 2 extends into a cavity of the clamping jaw 1, two fixing nuts 3 are sleeved on the butterfly-shaped fastening screw rod 2 in a threaded manner, and a foldable hand lever 4 is fixedly connected to the rear end of the clamping jaw 1.
The foldable hand lever 4 comprises a fixing rod 41, a connecting rod 42 and a hand lever 43, the fixing rod 41 is fixedly connected with the rear end axis of the clamping jaw 1 in the vertical direction, and the fixing rod 41, the connecting rod 42 and the hand lever 43 are respectively connected through rotating shafts. The foldable hand-operated lever 4 is distributed in a Z shape with the clamping jaw 1 after being opened, so that the strength of operators can be effectively saved. When operating personnel carries out actual scene earth connection operation, embolia the earth connection insulation grab handle in clamping jaw 1 inner chamber through the earth connection opening, utilize butterfly fastening screw 2 and two fixation nut 3 control the elasticity of clamping jaw 1, behind clamping jaw 1 presss from both sides the earth connection insulation grab handle, operating personnel according to installing, the needs of demolising clockwise, anticlockwise rotation collapsible hand pole 4 screw up or the spiral earth connection of back-off. After the grounding wire operation of the operator is completed, as shown in fig. 2, the foldable hand lever 4 can be folded for carrying.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
