Description
Technical field
A kind of earth connection dop of the utility model, relates to a kind of operation tool that connects earth connection.
Background technology
In power line overhauling operation, for guaranteeing handling safety, before maintenance, need quilt maintenance circuit reliable ground; The earth connection dop using at present, be double tongue type for connecting the connector lug of earth connection and overhead bare conductor, above-mentioned double tongue type dop uses comparatively general on straight line pole, while articulating on strain rod tower, because circuit is not level, double tongue type dop can not be bending, and reality articulates very inconvenient while use, waste time and energy.
In addition, because of the sectional area of the steel reinforced aluminium conductor of transmission line different, need to be equipped with the double tongue type dop of Multiple Type, not only can increase cost, and in real work, also be difficult to realize coupling completely, the dop that uses size " to put up with ", cause occurring that wire contacts tension or the problem of contacted pine with dop, cause ground connection unstable, make operation process have potential safety hazard, even entail dangers to operating personnel's life security.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is: provide a kind of and increase work efficiency and the earth connection dop of operational security.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is a kind of earth connection dop, comprise action bars, coupler body, for the adjustment sheet of attended operation bar and coupler body, gib head and screw mandrel, on described coupler body, be provided with the earth connection nut for dead earth line, described gib head is flexibly connected with coupler body by bearing pin, described gib head one end is connected with the top of screw mandrel, the other end of described gib head is to form the closed free end contacting with coupler body, connecting portion at screw mandrel and gib head is set with nut sleeve, between the bottom of described screw mandrel and action bars, be provided with deviator.
Described deviator is universal shaft coupling.
Described adjustment sheet is fixedly connected with the shackle that action bars top arranges by locking nut.
Compared with prior art, the beneficial effect having is the utility model: the earth connection dop in the utility model can swing and fix in certain angle, realizes the function of the wire ground connection that adapts to different gradients; Simultaneously, by universal drive shaft connected device is set between action bars and screw mandrel, by the rotation that rotarily drives screw mandrel of action bars, nut sleeve is upwards released, drive inside the withdrawal with coupler body of free end of gib head to form closed contact, work in coordination with and compress wire, be grounded the good contact of line card head and wire, and can adapt to the wire of different wire diameters, guarantee reliable ground; Above-mentioned earth wire clip header structure is simple, and cost of manufacture is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is that action bars, 2 is that coupler body, 3 is that adjustment sheet, 4 is that locking nut, 5 is that gib head, 6 is that screw mandrel, 7 is that nut sleeve, 8 is that deviator, 9 is that earth connection nut, 10 is earth connection.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, a kind of earth connection dop, comprise action bars 1, coupler body 2, adjustment sheet 3, gib head 5 and screw mandrel 6 for attended operation bar 1 and coupler body 2, on described coupler body 2, be provided with the earth connection nut 9 for dead earth line, described gib head 5 is flexibly connected with coupler body 2 by bearing pin, described gib head 5 one end are connected with the top of screw mandrel 6, the other end of described gib head 5 is to form the closed free end contacting with coupler body, be set with nut sleeve 7 at screw mandrel 6 and the connecting portion of gib head 5, between the bottom of described screw mandrel 6 and action bars 1, be provided with deviator 8.
Described action bars 1 adopts insulating material to make, and is superposed to Collapsible structure by more piece, can adapt to the operational requirements of differing heights; Described deviator 8 adopts universal shaft coupling, and in the time of rotation action bars 1, action bars 1 can drive screw mandrel 6 to rotate by universal shaft coupling; Described adjustment sheet 3 is fixedly connected with action bars 1 by locking nut 4, can realize by adjusting locking nut 4 object of adjusting angle between coupler body 2 and action bars 1.
Operation principle of the present utility model is: install earth connection additional on overhead transmission line time, first by earth connection nut 9 by firm reliable ground connection earth connection 10 being fixed on coupler body 2, unclamp locking nut 4, adjust the angle between coupler body 2 and action bars 1, after angle adjustment is good, tighten locking nut 4, by above-mentioned adjustment, make earth connection dop can adapt to the wire of different gradients.
Gib head 5 is hooked on the wire that needs ground connection, rotation action bars 1, action bars 1 drives screw mandrel 6 to rotate by deviator 8, nut sleeve 7 is upwards released, the free end of drive gib head 5 is inwardly regained and coupler body 2 forms closed contact, works in coordination with and compresses wire, is grounded the good contact of line card head and wire, and can adapt to the wire of different wire diameters, guarantee reliable ground.
After service work completes, while needing dismounting to be mounted on the earth connection on overhead transmission line, reverse rotation action bars 1, thus drive screw mandrel 6 to rotate, nut sleeve 7 is return downwards, and gib head 5 unclamps wire, can unload lower draw-bar.
Undertaken after above-mentioned improvement by earth wire dop, maintainer not only can be articulated to earth connection dop on the wire that needs ground connection easily, also can easily earth connection once be disassembled, thereby reduce the operating time, reduce labour intensity, alleviated maintainer's workload.
Meanwhile, the earth connection dop after use improves can also shorten the power failure preparation time of transmission line greatly, has produced good social benefit.
By reference to the accompanying drawings the utility model is explained in detail above, but the utility model is not limited in above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
