Description
Technical field
The utility model relates to the power line construction jig, device and the rear card of charged for replacement 220kV electric power circuit insulator when relating in particular to for power line construction.
Background technology
Up to the present, 220 kilovolt that put into operation have reached more than 4846 kilometers.The version of insulator string is divided two kinds of simply connected and duplexs, and duplex plate gold utensil proportion is larger, and existing machete jig is not suitable with more changing jobs of large load insulator in the 220kV circuit conductors on quad bundled, and the short circuit air gap is more, and leading screw can be dispatched little.
The utility model content
The technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part, and a kind of device and rear card for changing insulator be provided,, it be used for to be changed under the large load of 220kV circuit, on the strain tower because of broken by lightning or self-destruction, deteriorated glass, porcelain insulator.The use of this straight line bent plate jig, having increased the effective air gap of live line working and leading screw can dispatch, and guarantees power supply reliability, makes 220kV line security, stable, reliably operation.
Change the 220kV strain insulator, namely, because of broken by lightning or self-destruction, deteriorated glass, porcelain insulator, the mechanical load transfer that strain insulator/string must be born is to jig, make insulator/string not be subjected to pulling force, be in " coming to nothing " state, i.e. free falling body state could be changed the strain insulator that damages/string.When changing, also need consider the short circuit distance of jig leading screw, and the effective insulated lengths that guarantees to satisfy insulation pulling plate.
The technical scheme that the utility model solve the technical problem employing is: a kind of device for changing insulator is provided, comprise front card, rear card and insulation pulling plate, especially: connect lead screw assembly between described rear card and the described insulation pulling plate, described rear card comprises straightway and bending section, be provided with the recessed round tube hole that is complementary with described lead screw assembly in the straightway side of described rear card, after described lead screw assembly passes the recessed round tube hole of described rear card from the outside of described rear card, affixed with described insulation pulling plate, the room of yoke plate after the side central authorities of the bending section of described rear card are provided with for clamping, and be provided with location hole perpendicular to this empty place; One end and the front yoke plate of described front card are affixed, and the other end and described insulation pulling plate are affixed.
A kind of rear card of the device for changing insulator also is provided, described rear card comprises straightway and bending section, the straightway side of described rear card be provided with described device in the recessed round tube hole that is complementary of lead screw assembly, after described lead screw assembly passes the recessed round tube hole of described rear card from the outside of described rear card, affixed with described insulation pulling plate, the room of yoke plate after the side central authorities of the bending section of described rear card are provided with for clamping, and be provided with location hole perpendicular to this empty place.
Described room is the draw-in groove take described rear card central axis as line of symmetry, and described location hole is for perpendicular to this draw-in groove and two location holes being parallel to each other.
Compare with prior art, the beneficial effects of the utility model are: when the jig load is 98KN behind the utility model, without distortion and crackle.Jig is easy to assembly, and upper and lower jig is the energy one man operation all, has saved the labour; Not only reduce the short circuit distance of leading screw, can also carry out charged for replacement to insulator string faster, thereby safely, high-quality and efficiently finished production task.For example, general 220 KV transmission line calculated loads are 10MW, and the activity duration calculated with 2 hours, and 200,000 degree of can powering are amounted to into 80,000 yuan of RMB (1 degree electricity is by 0.4 yuan of consideration) more.
Description of drawings
Fig. 1 is that the master who blocks behind the utility model looks schematic diagram;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation that the utility model is used to change the device of insulator.
Embodiment
Below in conjunction with accompanying drawing content of the present utility model is described in further detail.
Referring to figs. 1 through shown in Figure 3, a kind of device and rear card for changing insulator, described device comprises front card 60, rear card 10 and insulation pulling plate 40, connect lead screw assembly 20 between described rear card 10 and the described insulation pulling plate 40, described rear card 10 comprises straightway 11 and bending section 12, is provided with the recessed round tube hole 13 that is complementary with described lead screw assembly 20 in straightway 11 sides of described rear card 10, recessed garden through hole 13, when being embedded, lead screw assembly 20 supporting plates are unlikely to unbalance stress, and stressed rear slippage.
After described lead screw assembly 20 passes the recessed round tube hole 13 of described rear card 10 from the outside of described rear card 10, affixed with described insulation pulling plate 40, existing machete card screw mandrel is inboard at jig, occupies insulation distance, and the effective travel of screw mandrel is lacked, is easily come off, and screw mandrel is not easy to operate.Then block 10 screw component 20 in the jig outside, the screw mandrel stroke is long, and is simple to operate up and down, and the assurance insulation distance.
The room 14 of yoke plate 50 after the side central authorities of the bending section 12 of described rear card 10 are provided with for clamping, and be provided with location hole 15 perpendicular to these 14 places, room; One end and the front yoke plate 70 of described front card 60 are affixed, and the other end and described insulation pulling plate 40 are affixed.
Described room 14 is the draw-in grooves take described rear card 10 central axis as line of symmetry, and described location hole 15 is for perpendicular to this draw-in groove and two location holes being parallel to each other.
