Description
Technical field
The present invention relates to high voltage transmission line live work field of tool, particularly a kind of multifunctional length adjustable insulating insulator bracket.
Background technology
At present, due to the difference of the factors such as the residing environment of transmission line, there is inconsistent phenomenon in 220 KV transmission line strain insulator string insulation configuration, and the sheet number of strain insulator string is from 15---and 19 are not etc.After these insulators are damaged or are deteriorated, the insulation level of bunch of insulator will reduce greatly, has a strong impact on the safe operation of transmission line.Therefore must change in time.Changing insulator can adopt power failure operation or two kinds of diverse ways of live line working to carry out.At present, for the consideration to power supply reliability, the methods that adopt live-line replacing more.When live-line replacing insulator, must use for insulator sheet number the insulating insulator bracket of different length.
In order to realize the replacing of the insulator string different to insulator sheet number, work unit just has to purchase the insulating insulator bracket of different length, causes the waste of instrument procurement payment, insulating tool keeping and deposits difficulty and strengthen.In addition, before live line working, in preparation tool, because the length of different bottle-holding racks differs for 146mm × n (n is insulator sheet number), difference is not very large, easily mistake is taken and the inconsistent bottle-holding rack of on-the-spot actual insulation substring length, causes operation to carry out.
Summary of the invention
The object of the invention is the replacing insulator job requirements in order to meet different length strain insulator string, spy provides a kind of multifunctional length adjustable insulating insulator bracket.
The invention provides a kind of multifunctional length adjustable insulating insulator bracket, it is characterized in that: described multifunctional length adjustable insulating insulator bracket, comprises conductor wire end jig 1, suspension member 2, main bottle-holding rack 3, adjustable bottle-holding rack 4, whorl brace rod 5;
Wherein: the right-hand member of main bottle-holding rack 3 is fixed with suspension member 2, conductor wire end jig 1 connection hanging piece 2; The right-hand member of adjustable bottle-holding rack 4 inserts the left end of main bottle-holding rack 3, and insertion depth can regulate, and by through hole and finger setting on adjustable bottle-holding rack 4; The left end of adjustable bottle-holding rack 4 is connected with whorl brace rod 5.
Described conductor wire end jig 1, comprises pulley yoke 101, pulley 102, crossbearer 103, hook 104;
Pulley yoke 101 is fixedly mounted on crossbearer 103 tops, and pulley 102 is arranged on pulley yoke 101, and hook 104 is arranged on crossbearer 103 bottoms.
Described main bottle-holding rack 3 and adjustable bottle-holding rack 4 are rod member package assembly, after the two connects, form semi-cylindrical structure.
After described main bottle-holding rack 3 is connected with adjustable bottle-holding rack 4, in vertical member direction, with crossbeam, form ladder-shaper structure.
Advantage of the present invention:
Multifunctional length adjustable insulating insulator bracket of the present invention, length can be adjusted, and can meet the replacing job requirements of the insulator string different to insulator sheet number, can replace multiple bottle-holding racks of original different length.Save the procurement payment of the insulating insulator bracket of buying different length.Save the parking space of instrument, reduced insulating tool keeping and deposited difficulty.Can decompose, easily assembling, is convenient to vehicle transport and a dead lift.By installing additional, end is fixed and suspension arrangement can change insulated ladder into, passes in and out highfield for operating personnel.

Embodiment
Embodiment 1
The present embodiment provides a kind of multifunctional length adjustable insulating insulator bracket, it is characterized in that: described multifunctional length adjustable insulating insulator bracket, comprises conductor wire end jig 1, suspension member 2, main bottle-holding rack 3, adjustable bottle-holding rack 4, whorl brace rod 5;
Wherein: the right-hand member of main bottle-holding rack 3 is fixed with suspension member 2, conductor wire end jig 1 connection hanging piece 2; The right-hand member of adjustable bottle-holding rack 4 inserts the left end of main bottle-holding rack 3, and insertion depth can regulate, and by through hole and finger setting on adjustable bottle-holding rack 4; The left end of adjustable bottle-holding rack 4 is connected with whorl brace rod 5.
Described conductor wire end jig 1, comprises pulley yoke 101, pulley 102, crossbearer 103, hook 104;
Pulley yoke 101 is fixedly mounted on crossbearer 103 tops, and pulley 102 is arranged on pulley yoke 101, and hook 104 is arranged on crossbearer 103 bottoms.
Described main bottle-holding rack 3 and adjustable bottle-holding rack 4 are rod member package assembly, after the two connects, form semi-cylindrical structure.
After described main bottle-holding rack 3 is connected with adjustable bottle-holding rack 4, in vertical member direction, with crossbeam, form ladder-shaper structure.
In the work of actual live-line replacing insulator, taking insulator sheet number as 18 as example, the length that operating personnel can calculate bunch of insulator is: L=146 × 18=2628mm, by adjusting the adjustable part of bottle-holding rack, the total length of bottle-holding rack and the length of bunch of insulator are adapted.Bottle-holding rack is connected and fixed in corresponding connection hole by connecting bolt.Then, earth potential working personnel carry insulation and transmit rope and arrive at the cross-arm-end of insulator string to be replaced, hang up properly and transmit rope.Ground Operation personnel are restricted the bottle-holding rack of adjusting length are passed to earth potential working personnel place by transmission.Earth potential working personnel insert the bolt of cross-arm-end fixture the manhole of insulator string two connecting plates, fastening nut.Meanwhile, equal potential working personnel enter insulator string conductor wire end job position by insulated flexible ladder, by rope, bottle-holding rack is lifted to job position, and the connection annulus of bottle-holding rack is suspended on the hook under overhang insulation jig.Then by shifting the method for wire tension, whole string insulation is pitched on insulating insulator bracket, easily completed the replacing that damages insulator by operating personnel.
