Described insulation bridge plate, for be formed by several sections of connections, adopts detachable being actively coupled between several sections;
Described tensioning apparatus is lead screw device;
Described cross-arm side yoke plate hook includes the supporting bracket of sheet, the end of described supporting bracket is provided with an auxiliary hook, described auxiliary hook includes threaded peg, the end of supporting bracket is provided with contiguous block, contiguous block is provided with the screwed hole passed for peg, the axis of this screwed hole is parallel with supporting bracket, setscrew nut is provided with above screwed hole with on the peg of below, supporting bracket is provided with the location hole of a row along the length direction of supporting bracket, also include the hook groove that can snap in cross-arm side triangle yoke plate, this hook groove can be locked in any location hole place of supporting bracket according to the length selection of insulator string thus adapt to different insulator strings,
Cross-arm side yoke plate hook is connected with one end of tensioning apparatus, and the other end of tensioning apparatus is connected with insulation bridge plate, and the other end of insulation bridge plate is then linked up with side of wire yoke plate and is connected.
In use, the shaft tower position arriving Awaiting Overhaul by interruption maintenance operating personnel, is first assembled into dormant state by the folding means of instrument to this synthetic insulator outlet bridge.
Operating personnel carries a transmission rope and steps on the insulator string position of tower to Awaiting Overhaul, is passed on shaft tower by synthetic insulator outlet bridge by transmitting rope.
Operating personnel ties up dual control safety belt, be displaced to strain insulator string triangle yoke plate place, the hand-held synthetic insulator outlet bridge assembled, first to hang over side of wire yoke plate on square yoke plate and to be supported to place by supporting leg, then being hung on triangle yoke plate by cross-arm side yoke plate and hang up properly auxiliary hook.
Operating personnel tightens up the screw mandrel of tensioning apparatus, makes outlet bridge be in tight state.
Safety belt moves on on composite insulation substring by operating personnel, take crouching formula pin tread line bridge hand steered the upper insulator string of vertical arrangement, moved by the side small step of cross-arm side guiding line and carry out outlet.
After the service work of wire position completes, operating personnel returns cross-arm side along outlet bridge, eases out the screw mandrel of tensioning apparatus, removes outlet bridge and transfers to an other phase, repeat above action until operation completes.
Described supporting leg is telescoping support leg.
The structure realizing telescoping support leg has a lot, itself or be hinged between two by more piece pipe, or for be nested in together by 2-section pipe, threaded engagement is set at mutual contact-making surface.
Described lead screw device is two-pass lead screw device.
Described insulation bridge plate adopts novolac epoxy resin frp layer pressing plate.
Strain insulator string outlet bridge is arranged between wire and cross-arm, if there is induced voltage in wire, just likely conduct to operating personnel's body part by outlet bridge, there is shock hazard, meanwhile, also likely occur operating personnel's fault rod climbing, outlet bridge is arranged on the situation on live wire by mistake, this just needs the bridge plate of outlet bridge, and higher dielectric strength should be had to have certain mechanical strength again, therefore adopts novolac epoxy resin frp layer pressing plate.
In sum, the utility model following advantage compared to existing technology:
Composite insulation substring outlet bridge of the present utility model, effectively can solve the 220kV transmission line interruption maintenance adopting strain insulator vertical arrangement composite insulation substring.Have employed tensioning mode innovatively to install, the lateral load of instrument is converted into longitudinal tension force, significantly reduce the weight of instrument, this instrument one man operation can carry out installation and removal.Because the bridge plate of outlet bridge have employed high-strength insulating material, also can prevent induction of electric shock and fault rod climbing from getting an electric shock.The parts such as this tool set is linked up with by side of wire yoke plate, insulation bridge plate, stretcher, cross-arm side yoke plate hook form, have that volume is little, quality is light, simple to operation, the advantage such as be easy to carry about with one, complete an outlet bridge installation and only need 5-10min, alleviate the labour intensity of operating personnel dramatically, increase work efficiency and operational security.
After this instrument has been developed, analog line carries out repeatedly try out, applied in the interruption maintenance of strain tower.Adopt the composite insulation substring outlet bridge newly developed, field operation personnel complete interruption maintenance work rapidly smoothly efficiently.Field operation personnel are reflected, 220kV vertical arrangement composite insulation substring outlet bridge is reasonable in design, lightweight, easy to carry; Install, remove simply, labour intensity is little, and required personnel are few, and effect of field application is good.
