Concrete pole ground wire reset device

Abstract

The invention provides a concrete pole ground wire reset device, and relates to the technical field of overhead transmission line construction. The concrete pole ground wire reset device comprises a lifting device and a wire clamp fixing device, wherein the lifting device comprises a telegraph pole detachable clamp, a support and a pair of fixed pulleys symmetrically arranged on the support, the telegraph pole detachable clamp is arranged above a telegraph pole ground wire hanging point, and the support and the telegraph pole detachable clamp are fixedly connected; the wire clamp fixing device comprises a wire clamp and a bolt penetrating device positioned at the upper end of the wire clamp. The device is reasonable in structural design, simple and convenient in operation and convenient to carry and use, and the device is used in ground wire reset operation, so that a great deal of time and manpower can be saved, the task difficulty and labor intensity are greatly reduced, the personal safety of workers is guaranteed, the work efficiency is improved, and the device has good social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of overhead transmission line construction, in particular to a cement pole ground wire reset device. Background technique [0002] In the construction of overhead power transmission lines using cement poles, the ground wire of the cement poles is connected to the hanging point with a suspension clamp, and the connection is fixed with bolts. Due to wind force, corrosion, thermal expansion and contraction, etc., the pins of the bolts are easy to corrode and fall off. , And then cause the ground wire of the cement pole to fall off. [0003] Since there is no transmission rope hanging point above the ground wire hanging point, it brings great difficulties to the ground wire reset. The traditional method can only be reset by manpower shouldering the ground wire, but because the distance between the cross arm and the ground wire hanging point is 2.5 meters, the operator cannot operate on the cross arm, they need ...

[0002] In the construction of overhead power transmission lines using cement poles, the ground wire of the cement poles is connected to the hanging point with a suspension clamp, and the connection is fixed with bolts. Due to wind force, corrosion, thermal expansion and contraction, etc., the pins of the bolts are easy to corrode and fall off. , and then cause the ground wire of the cement pole to fall off

[0003] Since there is no transmission rope hanging point above the ground wire hanging point, it brings great difficulties to the ground wire reset. The traditional method can only be reset by manpower shouldering the ground wire, but because the distance between the cross arm and the ground wire hanging point is 2.5 meters, the operator cannot operate on the cross arm, they need to climb to the upper end, carry the ground wire to the hanging point with their shoulders, align the suspension clamp connecting plate with the screw hole of the fixed hanging point of the ground wire, insert the screw, tighten the screw and then installation pin

The ground wire of the two gears is nearly 40 kg, and it is difficult for the operator to exert force on the pole. The reset of the ground wire is always a difficult problem in maintenance
