Description

A combination tool for installing grounding wires with special-shaped wire clips

technical field

The invention relates to a combined tool, in particular to a combined tool for installing grounding wires with special-shaped wire clips.

Background technique

During the power line outage operation, it is necessary to install a grounding wire on the pole. In the process of climbing poles, due to factors such as personnel skill level, use of insulating gloves, and location restrictions, it is often inconvenient to assemble and disassemble the grounding wires, and the work efficiency is low. Generally, it takes about 15 minutes to install a set of grounding wires after the electrical inspection; at the same time, In power lines, high and low voltage lines are often erected on the same pole, multi-circuit lines on the same pole, and other situations where it is not convenient to install grounding wires manually. When working at the position of the grounding wire, the body needs to be protruded far away to install the grounding wire. There is a risk of falling from a height and touching other live wires to cause electric shock.

At the same time, the current on-site operation requires the use of insulating grounding rods with screw-locking functions. When personnel twist the insulating rods, their hands are sore, they feel tired, the speed is slow, and even the twisting is not tight in daily work. , causing the ground rod to slip off the conductor.

When working in this way, personnel can install and disassemble the grounding wire on the pole tower, and can also complete the installation and disassembly of the grounding wire of the electrical facilities 6 meters away from the ground on the ground. In addition, when the power lines are erected on the same pole with high and low voltage, multi-circuit lines on the same pole, and other situations where it is not convenient to manually install the grounding wire, the low-voltage line cooperates with the power outage or other lines erected on the same pole. The grounding wire can only be installed at a far position, avoiding the risk of high fall and electric shock. At the same time, it avoids cooperating with power failure, improves the reliability of power supply, reduces the workload of personnel who install the grounding wire, and prevents the situation that personnel are easily tired when twisting the insulating rod.

In addition, the current shape of the collet makes the overall stress on the collet uneven, and the collet cannot be firmly suspended on the wire.

Contents of the invention

Further, the wire clip is provided with a cavity, and one end of the screw is rotated on the cavity, and as the screw rotates, the wire clip is driven to engage or separate from the collet. The wire clip will gradually bite into the clamp, so that the special-shaped wire clamp will be in close contact with the wire at the pre-grounded part of the power line and will not come out. When the screw rod is unscrewed through the internal thread through hole of the screw rod support, the wire clip will be gradually separated from the chuck, so that the special-shaped wire clamp is separated from the wire, and the grounding wire is removed.

Further, the collet includes an arc-shaped bending portion, a vertical section connected to one end of the arc-shaped bending portion, a screw support member perpendicular to one end of the vertical section, a second vertical section vertically arranged at one end of the screw support member, and Clamping bolts are arranged on the two vertical sections.

Compared with the prior art, the beneficial effects of the present invention are specifically as follows:

(1) The collet of the present invention has a special shape, and its appearance is similar to an "S"-shaped structure. This shape can ensure that after the collet is inserted into the wire, the supporting force of the wire to the curved collet is at the same level as the gravity of the special-shaped clip itself On the other hand, the special-shaped clamp can ensure that the curved clamp can be firmly suspended on the wire due to its unique structural design.

(2) In the present invention, the rod body and the screw rod are flexibly connected. The vertical rod and the horizontal rod are respectively inserted into the horizontal clamping seat and the vertical clamping base through the holes, so that the insulating rod and the special-shaped clamp are clamped. The tool drives the insulating rod to move to realize the removal of the grounding wire, and also facilitates the separation of the rod body and the screw rod after completion.

By adding different numbers of insulating rods, the operator can easily install the grounding wires in places where the height of the grounding wire installation point is 6 meters or less. You can stand on the ground to complete the assembly and disassembly of the ground wire. After the power failure of the high and low voltage lines erected on the same pole, it is necessary to install the grounding wire of the upper power line through the lower power line; After the line is powered off, it is inconvenient to manually install the electrical work field of the grounding wire. At the same time, the electric insulating operating rod of the combination tool can be used as a common insulating rod, and it is used in the operation and maintenance fields such as the operation of electrical equipment and the removal of foreign objects in power lines, effectively reducing the installation of high and low voltage on the same rod, the erection of multi-circuit lines on the same rod and the inconvenience of personnel When the ground wire is installed, low-voltage lines and adjacent lines are required to cooperate with power outages, which improves the reliability of power supply, reduces the risk of personal electric shock and high fall, and has very good operating capabilities.

(5) When the combination tool is not used to assemble and disassemble the grounding wire, the present invention can be used as an ordinary insulating rod, and is applied in the operation of electrical equipment and the removal of foreign objects in power lines, etc., and has good versatility.
