Abstract
The utility model discloses a portable insulation maintenance bridge, comprising a main bridge body, wherein, the main bridge body is made of high strength insulating materials; the tail end of the main bridge body is connected with a pole and tower cross arm fixation device by a second reinforcement hoop to be convenient for the connection with an insulator pole and tower cross arm; the head end of the main bridge body is connected with a hook by a first reinforcement hoop and the hook is hung at the front end of the insulator; the main bridge body is provided with an expansion part and the expansion part is sheathed inside the main bridge body and can stretch or retract if necessary; an adjusting pin is arranged between the main bridge body and the expansion part. The utility model made of high strength insulating materials has the advantages of retractable assembling, convenient installation, adjustment and carrying, being capable of using bridge outgoing line without trampling and injuring the insulator umbrella skirt in outgoing line process, improving work efficiency, reducing outage time and strengthening security and reliability, which is particularly suitable for installation, replacement and inspection of composite insulators on the 110KV power transmission line and 220KV power transmission line.
Description
Technical field:
The utility model relates to electric power overhaul equipment, particularly installation, replacing and the testing fixture of 110KV, 220KV transmission line turnover strain insulator shaft tower composite insulator.
Background technology:
Existing maintenance gap bridge characteristics are length that fix, unadjustable, heaviness, installation trouble, only are applicable to the 110KV transmission line, and do not have insulation property.Zhengzhou electric company in 2006 goes into overdrive Zhengzhou area 110KV, 220KV and above transmission line have been carried out large tracts of land replacing composite insulator, the dress that a large amount of need of work operating efficiencies is higher, replacing and testing fixture occurred at synthetic insulator inspection work in 2007.
Summary of the invention:
Technical problem to be solved in the utility model is exactly to provide a kind of portable insulation maintenance to pass a bridge at having problems such as overhauling gap bridge naked performance, heaviness now, select for use the high-strength insulation material to make, have the advantages that material is light, insulation property are high, and scalable assembling, regulate length, easy to carry, be applicable to 110KV, 220KV transmission line.
The technical solution adopted in the utility model is:
A kind of portable insulation is passed a bridge, and includes the gap bridge main body, and wherein: the gap bridge main body adopts the high-strength insulation material to make; The tail end of gap bridge main body is strengthened hoop by second and is connected with shaft tower cross-arm fixture, so that be connected with insulator shaft tower cross-arm; The head end of gap bridge main body is strengthened hoop by first and is connected with hook, and hook can hang over the insulator front end.
The gap bridge main body has pars contractilis, and pars contractilis is socketed in the gap bridge main body, and can stretch as required or indentation.
During work, movable in the gap bridge main body for preventing pars contractilis, and the control collapsing length, be provided with the adjusting pin between gap bridge main body and the pars contractilis
The beneficial effect that the utility model can reach is:
1, the utility model main body selects for use the high-strength insulation material to manufacture, two ends adopt metal to manufacture, front end is installed in the insulator front portion, the rear end is installed in shaft tower cross-arm proper site, and the staff installs, can be along the gap bridge outlet, in going out line process, can not trample, damage the insulator full skirt, increase work efficiency, reduce interruption duration, reliability tightens security.
2, length is regulated in the utility model and scalable assembling, and is easy to carry, safe and convenient to use quick, is particularly useful for installation, replacing and the inspection of composite insulator on 110KV, the 220KV transmission line
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, this portable insulation maintenance is passed a bridge, and includes gap bridge main body 4, and gap bridge main body 4 adopts the high-strength insulation material to make, and gap bridge main body 4 has pars contractilis 3; The tail end of gap bridge main body 4 is strengthened hoop 6 by second and is connected with shaft tower cross-arm fixture 7, so that be connected with insulator shaft tower cross-arm; The head end pars contractilis 3 of gap bridge main body 4 is strengthened hoop 2 by first and is connected with hook 4, and hook 4 can hang over the insulator front end; During work, movable in gap bridge main body 4 for preventing pars contractilis 3, and the control collapsing length, be provided with between gap bridge main body 4 and the pars contractilis 3 and regulate pin 5.
During use; the testing staff is earlier according to power line tension insulator length; after regulating the length of pars contractilis 3; pin 5 is fixing with regulating; step on bar arrival then and need to detect insulator cross-arm place; the ground support staff utilizes rope that gap bridge is passed to the testing staff; the testing staff is installed in the insulator front portion with gap bridge front end hook 1 earlier; rear end shaft tower cross-arm fixture 7 is installed in shaft tower cross-arm proper site; detect insulator along 4 outlets of gap bridge main body then; in going out line process, can not trample, damage the insulator full skirt, effectively protected insulator.
