Description
Technical Field
The utility model relates to a transmission line maintenance of equipment especially relates to a wire turn-buckle of insulator is changed in electrified.
Background
At present, when the insulators are replaced on the linear pole towers of the transmission lines of 220KV and above in a live mode, wires connected with the insulators need to be disassembled and tightened to the upper cross arms, so that the wires are far away from the insulators, and a sufficient insulator replacement operation space is guaranteed. The existing wire tightening tool usually adopts a turn buckle, the two ends of the turn buckle are respectively hooked on the cross arm and the wire, the length of the turn buckle is shortened, and then the wire is tightened to the cross arm. Because the turn buckle is close to the wire, the operating personnel is easy to be shocked by the wire when adjusting the turn buckle, and the life safety of the operating personnel is threatened.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide a wire turn-buckle of insulator is changed in electrified, when the stringing operation, the operation personnel can keep away from the wire, avoid the operation personnel to receive the wire electric shock, provide the guarantee to operation personnel's life safety.
The technical solution of the utility model is that:
the wire tightener for live replacement of the insulator is characterized in that: including the supporting seat that has vertical centre bore, it has the lead screw to run through from top to bottom in the vertical centre bore of supporting seat, passes through threaded connection screw in the lead screw upper end, and screw one side sets up the pull rod, rotates installation lifting hook at the lead screw lower extreme, and the support frame is installed respectively to the both sides about the supporting seat, and the support frame lower extreme is equipped with two bayonets of arranging from beginning to end.
Preferably, the support frame is composed of a front support frame split body and a rear support frame split body which are hinged with the support seat, the two bayonets are respectively arranged at the lower ends of the front support frame split body and the rear support frame split body, the span between the front support frame split body and the rear support frame split body is adjusted, and the front support frame split body and the rear support frame split body are clamped on two angle steels with different intervals on the cross arm through the bayonets at the lower ends.
Further preferably, transverse bolts are respectively connected between the two front support frame split bodies and between the two rear support frame split bodies, so that the structural stability between the two front support frame split bodies and between the two rear support frame split bodies is improved.
Preferably, the two transverse pull rods are provided with front and rear opposite through holes, longitudinal bolts penetrate through the front and rear opposite through holes, bayonets at the lower ends of the front support frame split body and the rear support frame split body are clamped on the two angle steels, the transverse bolts automatically rotate, and the longitudinal bolts are fastened to improve the structural stability between the front support frame split body and the rear support frame split body.
Further preferably, an inverted U-shaped hanging bracket is arranged at the lower end of the screw rod, the lower end of the screw rod penetrates through a top plate of the inverted U-shaped hanging bracket, a stop block is welded at the end, penetrating through the inverted U-shaped hanging bracket, of the screw rod, and the lifting hook is hinged to the bottom end of the hanging bracket, so that the flexibility of the lifting hook is improved.
The utility model has the advantages that:
1. because the lead screw that runs through the supporting seat from top to bottom, install the screw in the lead screw upper end through the screw thread, rotate the lifting hook of installing at the lead screw lower extreme, install the support frame at the supporting seat left and right sides, fix the support frame at the cross arm, with lifting hook wire, rotatory screw promotes the lead screw, and then tightens up the wire to the cross arm through the lifting hook of lead screw lower extreme, keeps away from the wire as the screw at tight line operation position, makes the operating personnel keep away from the wire, avoids the operating personnel to receive the wire electric shock, provides the guarantee to operating personnel's.
2. Because the lifting hook rotates with the lead screw installation, at the rotatory in-process of lead screw, the lifting hook is not rotatory along with the lead screw with the wire hook, prevents that the wire from droing the lifting hook. 3. Because install the support frame in the supporting seat left and right sides, the wire turn-buckle that changes the insulator for this electrified provides fixed knot and constructs, guarantees the line tightening in-process and evaporates steamer tray structural stability.
