Description
Technical field
The utility model relates to a kind of 800 kilovolts of DC power transmission line six-multiple conductor line lifters.
Background technology
Composite insulator V string form is all adopted at ± 660 kilovolts and above DC power transmission line cathetus shaft tower, when changing insulator or annex, instrument in the past can only change a certain insulator string in V string, and cannot the insulator annexes such as grading ring be changed, and difficulty installed by instrument, has been difficult to service work.
Utility model content
The purpose of this utility model is to provide a kind of 800 kilovolts of DC power transmission line six-multiple conductor line lifters, can reach the object simultaneously changing V insulator string and annex thereof.
A kind of 800 kilovolts of DC power transmission line six-multiple conductor line lifters, comprise hand-hydraulic leading screw, its special feature is: be provided with steel tower connector on the top of described hand-hydraulic leading screw thus can be fixed on the cross-arm of steel tower, and the wire lever that stretches out of this hand-hydraulic leading screw bottom is then hooked line lifter by insulation pulling plate be connected with one six.
Wherein six hook line lifters comprise support, and this support is hinged with six roots of sensation suspension hook.
The utility model device has quality advantage light, quick for installation, can realize at right angle setting, efficiently solves the problem simultaneously can not changing V insulator string and grading ring.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of 800 kilovolts of DC power transmission line six-multiple conductor line lifters, (usual hand-hydraulic leading screw 2 forms by hand-hydraulic controlling organization and by wire lever 3 telescoping mechanism of pipeline connection, and hereinafter hand-hydraulic leading screw 2 specifically refers to wire lever 3 telescoping mechanism to comprise hand-hydraulic leading screw 2; Certainly the integrated hand hydraulic screw rod 2 above-mentioned Liang Zhong mechanism be fixed together can also be adopted).Be provided with steel tower connector 1 on the top of hand-hydraulic leading screw 2 thus can be fixed on the cross-arm of steel tower, the wire lever 3 that stretches out of this hand-hydraulic leading screw 2 bottom is then hooked line lifter by insulation pulling plate 4 be connected with one six.Wherein six hook line lifters comprise support 6, and this support 6 is hinged with six roots of sensation suspension hook 5.
Using method of the present utility model is:
During use, steel tower connector 1 and steel tower cross-arm bottom bolt are fixed, the top bolt of the other end and hand-hydraulic leading screw 2 is connected firmly, the pressure relief valve 8 of hand-hydraulic leading screw 2 is opened simultaneously and make leading screw be in most long status, then the both sides of insulation pulling plate 4 are connected respectively the wire lever 3 and six stretched out hand-hydraulic leading screw 2 bottom and hook line lifter, six conductors catches on by six roots of sensation suspension hook 5 respectively that hook line lifter with six again, swung by handle 7 and tighten up hand-hydraulic leading screw 2, six conductors is upwards mentioned, insulator string is relaxed, i.e. replaceable insulator and annex.
Claims (2)
