Description

A combination tool for installing a special-shaped wire clamp on a ground wire

Technical Field

The invention relates to a grounding wire assembly tool, in particular to a grounding wire assembly tool for installing a special-shaped wire clamp.

Background technique

During the power outage operation, it is necessary to climb the pole to install the grounding wire. During the climbing process, due to factors such as personnel skill level, the use of insulating gloves and location restrictions, it is often inconvenient to install and remove the grounding wire, and the work efficiency is low. Generally, it takes about 15 minutes to install a set of grounding wires after the power test; at the same time, in power lines, high and low voltages are often installed on the same pole, multiple lines on the same pole, and other situations that are not convenient for manual installation of grounding wires often occur. Low-voltage lines and other lines installed on the same pole are often required to be stopped, or when personnel work in a position where it is inconvenient to install the grounding wire, they need to lean out to a far position to install the grounding wire, which poses a risk of electric shock caused by falling from a high place and touching other live wires.

At the same time, it is currently required to use insulating grounding rods with a spiral locking function during on-site operations. When workers twist the insulating rods, their hands become sore, they feel very tired, and their speed is slow. In daily work, they even fail to tighten the rods, causing the grounding rods to slip off the conductors.

When working in this way, personnel can install and remove ground wires on the pole tower, or they can complete the installation and removal of ground wires for electrical facilities 6 meters above the ground on the ground. In addition, when high and low voltage are installed on the same pole, multiple lines are installed on the same pole, or other situations where it is inconvenient to install ground wires manually, the low voltage line is shut down in coordination or other lines installed on the same pole are shut down, and the operator does not need to lean out of the ground wire to install it, thus avoiding the risk of falling and electric shock. At the same time, it avoids coordinated power outages, improves power supply reliability, reduces the workload of personnel installing ground wires, and eliminates the situation where personnel are easily tired when twisting the insulating rod.

In addition, the current chuck shape makes the overall force of the chuck uneven, and the chuck cannot be firmly hung on the wire.

Summary of the invention

In view of the deficiencies in the prior art, the present invention has developed a combination tool for installing grounding wires with special-shaped wire clamps. Compared with other existing methods, the combination tool improves work efficiency, reduces operation time, reduces the number of power outage lines, and improves power supply reliability. It can solve the deficiencies in the prior art and has a convenient, fast and simple effect.

The technical solution of the present invention is specifically as follows:

A combined grounding wire installation tool with a special-shaped wire clamp comprises a clamp head, the clamp head is arranged on a screw support, a screw is movably arranged on the screw support, one end of the screw is movably connected to a wire clamp, and the other end is detachably connected to one end of a rod body, a handle is arranged at the other end of the rod body, the handle comprises a sleeve and a rod body connector, one end of the rod body connector is fixed to the end of the rod body, and the sleeve is movably sleeved on the outside of the end of the rod body;

Among them, a horizontal clamp is provided at the other end of the screw rod, a vertical clamp is provided on the horizontal clamp, a vertical rod is provided at one end of the rod body, a horizontal rod is vertically provided on the vertical rod, holes are provided on the horizontal clamp and the vertical clamp, and the vertical rod and the horizontal rod are respectively inserted into the horizontal clamp and the vertical clamp through the holes. The insulating rod is clamped with the special-shaped wire clamp, and after the bolt is clamped with an electric tool, the electric tool drives the insulating rod to move, so as to realize the removal of the grounding wire.

Furthermore, a cavity is provided on the wire clamp, and one end of the screw is rotatably arranged on the cavity. As the screw rotates, the wire clamp is driven to engage or separate with the clamp. The wire clamp will gradually engage with the clamp, so that the special-shaped wire clamp is in close contact with the wire at the pre-grounding position of the power line and will not fall out. When the screw is screwed out through the internal threaded through hole of the screw support, the wire clamp will gradually separate from the clamp, so that the special-shaped wire clamp is separated from the wire, and the grounding wire is removed.

Furthermore, the clamp includes an arc-shaped curved portion, a vertical section connected to one end of the arc-shaped curved portion, a screw support member arranged perpendicularly to one end of the vertical section, a second vertical section arranged perpendicularly to one end of the screw support member, and a clamping bolt is arranged on the second vertical section. In this way, the appearance of the clamp is similar to an "S"-shaped structure, and this shape can ensure that after the clamp is clamped into the wire, the supporting force of the wire on the bent clamp is on the same horizontal line as the gravity of the special-shaped wire clamp itself, so that the special-shaped wire clamp can ensure that the bent clamp can be firmly suspended on the wire due to its unique structural design.

Furthermore, the interior of the rod body is a cavity, and a first pin hole is provided on the cavity wall at the end of the rod body. The rod body connecting piece includes an insulating filler and a first bolt provided at the tail end of the insulating filler, a second pin hole is provided on the insulating filler, and a third pin hole is provided on the first bolt. The second pin hole corresponds to the third pin hole. After the rod body connecting piece is inserted into the cavity, the first pin hole, the second pin hole and the third pin hole correspond to each other, and the end of the rod body, the insulating filler and the first bolt are fixed by a pin.

Furthermore, a fixed base is provided between the first bolt and the sleeve. The fixed base is annular and has a cavity inside. A clamp hole is provided on the wall of the fixed base. A circular hole is provided at one end of the sleeve. The clamp connects the sleeve and the fixed base through the clamp hole and the circular hole.

Furthermore, the screw rod is driven to rotate by connecting an electric tool to the first bolt. The electric tool is a handheld electric drill equipped with a socket of corresponding size, an electric wrench, and other electric tools that can drive the first bolt to move.

Furthermore, the outer diameter of the insulating filler is consistent with the inner diameter of the end of the rod body, and the two fit tightly. The outer diameter of one end of the sleeve fixing base is consistent with the inner diameter of the sleeve, and they fit tightly. The outer diameter of one end of the sleeve fixing base is slightly larger than the outer diameter of the end of the insulating rod, so that there is a certain gap between the sleeve and the end of the rod body to ensure sufficient rotation margin.

Furthermore, the rod body is composed of a plurality of insulating rods assembled through insulating rod connectors, and a guard ring is provided at one end of the insulating rod body close to the handle.

Furthermore, a gasket is sandwiched between the fixed base and the first bolt to reduce wear between the bolt and the fixed base.

Furthermore, limiting grooves are provided on the upper and lower sides of the hole on the vertical clamping seat, the vertical rod is inserted into the horizontal clamping seat through the hole, and the horizontal rod slides into the limiting groove through the hole.

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

(1) The clamp of the present invention is of a special shape, and its appearance is similar to an "S"-shaped structure. This shape can ensure that after the clamp is clamped into the conductor, the supporting force of the conductor on the bent clamp is on the same horizontal line as the gravity of the special-shaped wire clamp itself, so that the special-shaped wire clamp can be firmly suspended on the conductor due to its unique structural design.

(2) The present invention provides a movable connection between the rod body and the screw rod. The vertical rod and the horizontal rod are respectively inserted into the horizontal clamp and the vertical clamp through the holes, so that the insulating rod and the special-shaped wire clamp are clamped. After the bolt is clamped with an electric tool, the electric tool drives the insulating rod to move, thereby realizing the removal of the grounding wire. After completion, it is also convenient to separate the rod body and the screw rod.

(3) The present invention can drive the rod body to rotate by using an existing electric tool, without the need for manual twisting, thus shortening the operation time.

(4) The present invention can be used in the field of installing combined or split-phase short-circuit grounding wires during power outage operations of electrical equipment. By adding different numbers of insulating rods, operators can stand on the ground to complete the installation and removal of grounding wires in places where the height of the grounding wire installation point is 6 meters or less. After the high and low voltage lines on the same pole are powered off, it is necessary to cross the lower power line to install the upper power line grounding wire, and after the multi-circuit electrical lines on the same pole are powered off, it is necessary to cross the lower power line to install the upper power line grounding wire, or after the single-circuit line is powered off, it is in the field of electrical operations where it is inconvenient to install the grounding wire manually. At the same time, the electric insulating operating rod of the combined tool can be used as an ordinary insulating rod and applied to the operation and maintenance fields such as electrical equipment operation and power line foreign body removal, effectively reducing the need for low-voltage lines and adjacent lines to cooperate in power outages when high and low voltage lines are installed on the same pole, multi-circuit lines are installed on the same pole, and when it is inconvenient for personnel to install grounding wires, thereby improving the power supply reliability, reducing the risk of electric shock and falling, and having very good operating capabilities.

(5) When the combined tool is not used to install or remove the ground wire, the present invention can be used as an ordinary insulating rod and applied to the operation of electrical equipment and the removal of foreign matter from power lines, and has good versatility.
