Fig. 2 is using state structural representation of the present utility model.
Fig. 3 is another using state structural representation of the present utility model.
Wherein: 1 positioning supports plate, 1-1 gap, 1-2 connecting hole 2 locate leading screw, 3 backstays, 3-1 gland, 4U type baffle plate, 5 leading role's steel, 6 angle steel welding portion, 7 leading screw decks, 8 connection leading screw, 9 action bars, 10 yoke plate decks, 11 insulators back-to-back.
Embodiment
Below in conjunction with accompanying drawing 1-3 and specific embodiment, utility model is described in further detail:
A kind of tangent tower replacing insulator string servicing unit as shown in Figure 1, it comprises two symmetrically arranged positioning supports plates 1 and the location leading screw 2 being connected described two positioning supports plates 1, the two ends of described location leading screw 2 respectively with corresponding positioning supports plate 1 threaded engagement, lead screw pair is formed between location leading screw 2 and positioning supports plate 1, described location leading screw 2 is two-way leading screw, two positioning supports plates 1 can be made to move in the opposite direction by rotational positioning leading screw 2 simultaneously, thus the distance between adjustment two positioning supports plates 1.Described positioning supports plate 1 is provided with connecting hole 1-2, and described connecting hole is used for being connected with the leading screw of existing replacing jig.
Described location leading screw 2 is provided with U-shaped baffle plate 4, and described U-shaped baffle plate 4 is in described location leading screw 2 central authorities and and for being rotatably assorted between described location leading screw 2, namely U-shaped baffle plate 4 does not affect the rotation of location leading screw 2.Location leading screw 2 is provided with snap ring, and described U-shaped baffle plate 4 can not be horizontally slipped on described location leading screw 2, and described U-shaped baffle plate 4, for blocking the top connecting portion of insulator 11 bulb or leading screw deck 7, limits its double swerve.Be provided with backstay 3 between described two positioning supports plates 1, for being rotatably assorted between described backstay 3 and two positioning supports plates 1, described backstay 3 is through described U-shaped baffle plate 4.By arranging backstay 3, two positioning supports plates 1 and U-shaped baffle plate 4 can not freely be rotated, when rotating location leading screw 2, two positioning supports plates 1 can only move horizontally, and can not rotate, in use, U-shaped baffle plate 4 also can not rock, and structural stability is better.
