Example Embodiment

[0032] In Embodiment 1, as shown in FIG. 1, the top line mechanism includes a U-shaped mounting frame 20 and a top line pulley 14, the mounting frame 20 is connected to the upper base 9, and the top line pulley is installed on the mounting frame 20. When the porcelain bottle 27 on the top pole is damaged, as shown in FIG. 7, the base 2 is positioned on the cross arm 29 of the electric pole. Sleeve the handle on the joint at the end of the adjusting screw 7, turn the handle to rotate the adjusting screw 7, so that the distance between the two shaft pins 10, 13 is shortened, the top line pulley 14 rises to remove the wire on the porcelain bottle 27, and move After the wire 28 is turned on, the top wire pulley supports the wire 28 again. After the wire 28 is removed from the porcelain bottle 27, the porcelain bottle 27 can be replaced. The electric wire 28 is removed from the porcelain bottle 27 by an auxiliary tool, which reduces the labor intensity. After the replacement is complet...

Example Embodiment

[0033] Embodiment 2, as shown in Figure 2, the top thread mechanism includes a sleeve 15, a screw 16 and a U-shaped top thread fork 19. The sleeve 15 is horizontally fixed on the upper base 9, and the screw 16 is threadedly connected in the sleeve 15 , The top line fork 19 is provided at one end of the screw 16, and the other end of the screw 16 is provided with a rotary joint 17. This structure is mainly used to remove the wire on the porcelain bottle outside the corner rod, and after the top wire fork is raised to contact with the wire by adjusting the screw, the screw is then rotated to push the wire forward and sideways.

Example Embodiment

[0034]Embodiment 3, as shown in Figure 3, the top line mechanism includes a sleeve 15, a screw 16, a U-shaped mounting frame 20 and a top line pulley 14. The sleeve 15 is horizontally fixed on the upper base 9, and the screw 16 is threadedly connected to the sleeve. In the barrel 15, one end of the screw 16 is provided with a rotary joint 17, and the other end is threadedly connected with a mounting sleeve 18, and a top line fork 19 is provided on the mounting sleeve 18; the mounting frame 20 is connected to the sleeve 15, and the top line pulley 14 is installed On the mounting frame 20. A U-shaped cable hook 21 can also be provided on the mounting sleeve 18 at the same time. This structure can not only be used to remove the wires on the top pole porcelain bottle, but also can be used to remove the wires on the corner pole porcelain bottle. The working principle for removing the wires on the porcelain bottle on the top pole is the same as that of embodiment 1, and the working prin...

Abstract

The invention relates to an auxiliary tool used for replacing porcelain insulators of a wire pole, wherein, an elevating mechanism is arranged on a pedestal; a mean line mechanism capable of removing wires on the porcelain insulators and supporting the removed wires is connected with the upper end of the elevating mechanism; the pedestal is located on a cross arm of the wire pole; the elevating mechanism is operated and drives the mean line mechanism to contact the wires which are then removed from the porcelain insulators, and then the porcelain insulators can be replaced. The invention has the advantages of simple operation, small labor intensity, and improvement of safety and convenience of operation during the process of replacing the porcelain insulators.

Description

technical field [0001] The invention relates to a power distribution tool, in particular to an auxiliary tool for replacing porcelain bottles on utility poles. Background technique [0002] When the power line distribution team is performing line maintenance and accident handling, it often encounters the need to replace porcelain bottles, that is, insulators. The current operation method is: first use a special wire tightening device to turn the wires on both sides of the porcelain bottle to be replaced inwards and horizontally. Fold towards each other, so that the wires bound on the porcelain bottle are in a loose state, and then replace the porcelain bottle. The used tightening device generally includes a wire tightener and a wire clamp. The wire tightener is composed of a ratchet with a handle and a ratchet assembly, and the wire tightener is connected with the wire clamp through a cable. When using above-mentioned tightening device to change porcelain bottle, there are ...
