Embodiment 1

[0029] For an installation tool for interphase spacers in this embodiment, please refer to Figure 1-2 , which is mainly composed of five parts: pulley 1, "eight-character" type jaw 2, connecting rod 3, right-angle fixing rod 4, lifting rod 5.

[0030] Among them, the pulley 1 is fixed at the middle connection of the clamping mouth 2, and plays a transmission role.

[0031] The "eight-character" type jaw 2 is composed of a large jaw 2-2 and a small jaw 2-3 on the same horizontal plane. The large jaw 2-2 is used to clamp the spacer bar, and the inner side of the large jaw 2-2 is installed with a Rubber strip 2-1, the rubber strip 2-1 acts as a fastening spacer to prevent sliding, the opening and closing of the large clip 2-2 and the small clip 2-3 are mutually exclusive, the large clip 2-2 Open, the small jaw 2-3 is closed, the small jaw 2-3 is opened, and the large jaw 2-2 is closed.

[0032] The connecting rod 3 plays the role of connection and transmission. The upper part ...

Abstract

The invention relates to a special tool for installing a phase-to-phase spacer, which is widely applied to the work of live installation of the phase-to-phase spacer with a fallen lower end in a power transmission line, and belongs to the technical field of power transmission line maintenance. Comprising a clamping opening used for clamping a metal rod at the lower end of the spacer, the clamping opening clamps or loosens the spacer through a connecting rod, the connecting rod is sleeved with a lifting rod capable of rotating with the connecting rod as the axis, and a limiting baffle used for preventing the lifting rod from being separated from the connecting rod is installed at the bottom of the connecting rod. The tail end of the lifting rod is provided with a clamping plate used for clamping a split conductor connecting plate or a conductor, and a driving mechanism used for driving the lifting rod to move towards the clamping opening is arranged between the clamping opening and the lifting rod. The device is convenient to install, is safe and reliable, improves the hot-line work efficiency, and reduces the work intensity and the safety risk of operators.

Description

technical field [0001] The invention relates to a special tool for installing interphase spacers, which is widely used in the work of live installation of interphase spacers whose lower ends have fallen off in power transmission lines, and belongs to the technical field of transmission line maintenance. Background technique [0002] Overhead transmission lines are the main roads for the transmission of electric energy, and their daily operation and maintenance is an important guarantee to ensure the safety and reliable power supply of the power grid. The interphase spacer is mainly used in the transmission line to prevent the line from galloping or even short circuit between phases due to external factors such as wind. However, due to the nature of the work and the influence of external conditions, the lower end of the interphase spacer sometimes becomes loose or even falls off, which poses a safety hazard to the reliable operation of the line. [0003] The installation of ...
