There is slot at the corresponding the attracted numbers place of described plate outer side.
The utility model is provided with lockweight between the open side and base of link, link is damage wires not, be hung on lockweight and link after on wire wire is pinned, link is avoided to come off from wire, prevent operating personnel from touching somersault coaster in side of wire operation mistiming on the one hand and may cause its risk of falling, jeopardize the safety of Ground Operation personnel, prevent on the other hand that operating personnel's amplitude in lifting rope ladder process is excessive to be caused link to depart from wire and somersault coaster is fallen the risk of hurting sb.'s feelings, improve safety in utilization.Base is connected with the connecting axle of coaster by insulation bearing, and coaster can be rotated around base, is convenient to adjust the direction of transmitting insulating cord.Shorten the activity duration by rotatable pulley-lifting rope ladder head and rope ladder moment like this, improve processing safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model lockweight open mode.
Fig. 2 is the structural representation of the utility model lockweight full state.
Fig. 3 is that schematic diagram is looked on a left side of Fig. 1.
Embodiment
As shown in Figure 1 to Figure 3, the utility model discloses a kind of transmission overhead line somersault coaster, comprise hook 1 and the coaster 2 being connected to its underpart.The top of hook 1 is link 11, bottom is base 12, is connected with lockweight 3 between the open side of link 11 and base 12.
The outer arm of link 11 open side upper end has the chute along its short transverse, and the length direction center line of chute is connected with screw rod 112, and the outer end of screw rod 112 is connected with cover type nut 111.Base 12 is surrounded by riser 121, base plate 122 and side plate 123, and riser 121 and base plate 122 surround L-type, and biside plate 123 separates from the both sides between riser 121 and base plate 122.The length of base plate 122 is greater than the diameter of link 11.Lockweight 3 is plugboard pin, comprises plate 31 and the cavity ring 32 being positioned at plate 31 upper end.There is slotted hole 311 at the length direction center of plate 31.Plate 31 is connected in chute, and both length direction center lines overlap.
Fastening spacing by cover type nut 111 between plate 31 and chute, the external diameter of cover type nut 111 is greater than the width of slotted hole 311 on plate 31.
Coaster 2 comprises the U-shaped frame 22 of insulating block 21 and fixed insulation pulley 21, and the two end axles of insulating block is connected with the biside plate of U-shaped frame 21 is vertical, and the blind end central vertical of U-shaped frame 22 is provided with connecting axle 23.Base plate 122 has insulation bearing 4, on base plate 122, the central hole of corresponding insulation bearing 4 inner ring has through hole, and the aperture of through hole is greater than the external diameter of connecting axle 23, and connecting axle 23 is connected with interference fit with the inner ring of insulation bearing 4 through rear from through hole.
Outside base plate 122, there is slot corresponding plate 31 position.
Operation principle of the present utility model is as follows: between the open side and base 12 of link 11, be provided with lockweight 3, link 11 not damage wires, hook 1 is hung on lockweight 3 and link 11 after on wire and is pinned by wire, link 11 is avoided to come off from wire, prevent operating personnel from touching somersault coaster in side of wire operation mistiming on the one hand and may cause its risk of falling, jeopardize the safety of Ground Operation personnel, prevent on the other hand that operating personnel's amplitude in lifting rope ladder process is excessive to be caused link to depart from wire and somersault coaster is fallen the risk of hurting sb.'s feelings, improve safety in utilization.Base 12 is connected with the connecting axle 23 of coaster 2 by insulation bearing 4, and coaster 2 can be rotated around base 12, is convenient to adjust the direction of transmitting insulating cord.Be elevated rope ladder head and shortening activity duration in rope ladder moment by rotatable coaster 2 like this, improve processing safety.
Before hook hangs wire, lockweight is in the state shown in Fig. 1, fastening by cover type nut 111.Be hung on by hook after on wire, unscrewed by cover type nut, lockweight is fallen automatically, in the slot on the inserted base base plate of lower end, wire pins by link together with lockweight, as shown in Figure 3, avoids hook to come off raising fail safe.
