Problems solved by technology

Generally, two people are required to disconnect and connect the lead wires when the insulating gloves are used. One person operates, and the other holds the lead wire fixing rod to fix the lead wires. When disconnecting and connecting the lead wires, the control requirements for the lead wires are relatively high, and it is difficult to cooperate and labor-intensive.
Sometimes it needs the support of lifting equipment, or due to certain conditions, it is inconvenient for two people to operate, and special fixtures are needed to meet the construction requirements.

Embodiment 1

[0042] See figure 1 , a structural diagram of the opening of the lead wire clamp tool for the edge glove operation method. A clamp tool for disconnecting lead wires in the glove operation method, comprising large molar teeth 18, small molar teeth 16, large molar tooth holders 1, jaw holders 17, upper insulating handle 7 and lower insulating handle 11, characterized in that: The large tooth 18 is connected to the head of the large tooth seat 1 through the large tooth pin shaft 19, the upper end of the tail of the large tooth seat 1 is connected to the upper insulating handle 7 through the pin shaft 2, and the lower end of the tail of the large tooth seat 1 is connected through the hinge shaft 3. Connect with the lower insulating handle 11, the middle part of the upper insulating handle 7 is connected with one end of the insulating connecting handle 6 through the connecting handle pin 5, the other end of the insulating connecting handle 6 is provided with a slider 9, and the sli...

Embodiment 2

[0055] Figure 4 It is a schematic diagram of clamp breaking and connecting lead wire operation. The clamps shown are in the closed state, the overhead main wire 20 is clamped between the large molar 18 and the jaw seat 17, and the disconnected and connected lead wire 21 is clamped between the small molar 16 and the jaw seat 17. Through the inherent structure of the clamp, the overhead main wire 20 is kept at a certain distance from the disconnecting and connecting lead wires 21, and the clamping is firm and difficult to move in series, which brings convenience to the subsequent operation of disconnecting and connecting the lead wires.

[0056] Figure 5 is a schematic diagram of the clamp used for the main wire stripping operation. Under the closed state of the tongs, by clamping the empty lead wire 20, breaking and connecting the lead wire 21, the wire stripping operation is performed on the lead.

[0057] Figure 6 Is the clamp used to install and hook clip and guard op...

Abstract

The invention relates to an insulating glove operation method broken lead clamp tool and a use method. The tool comprises a large jaw tooth, a small jaw tooth, a large jaw tooth seat, a jaw seat, an upper insulating handle and a lower insulating handle. The tool is characterized in that a sliding block is arranged at the other end of an insulating connecting handle; the sliding block is positionedin the chute of the lower insulating handle; a large jaw tooth adjusting bolt is arranged at the tail part of the lower insulating handle; the screw rod of the large jaw tooth adjusting bolt abuts against the sliding block of the connecting handle; a spring is arranged between the large jaw tooth seat and the lower insulating handle; the small jaw tooth is connected with the lower insulating handle through a small jaw tooth pin shaft; an adjusting handle is arranged at one end of the small jaw tooth; the other end of the adjusting handle abuts against a small jaw tooth adjusting bolt; the small jaw tooth adjusting bolt is screwed on the head of the lower insulating handle; and a torsional spring is arranged between the small jaw tooth and the jaw seat. According to the clamp, the large jaw tooth and the small jaw tooth are tightly meshed with the jaw seat by pressing the upper insulating handle, and a wire and a lead are clamped; the wire and the lead are fixed in position; and the corresponding distance is kept.

Description

technical field [0001] The invention belongs to the field of high-voltage power distribution operations, and in particular relates to a clamp tool for disconnecting lead wires in the insulating glove operation method and a use method thereof Background technique [0002] The power system is one of the most important infrastructures in the country. The urban power grid is the main component of the power system, and its position plays a pivotal role in the power system. Urban electricity consumption accounts for more than 70% of the country's electricity consumption. As the power load center, the urban power grid has the characteristics of high load density and high dependence of users on electricity. The increase of daily power supply load, or emergency repair of accidents, timely power supply and ensuring stable power supply are directly related to social harmony and smooth production, and must be given sufficient attention. [0003] With the increase of power consumption, ...
