Description

Portable anti-vibration hammer tool for replacing tension wires during power failure

technical field

The invention relates to a replacement tool, more specifically to a tool for replacing a tension wire anti-vibration hammer.

Background technique

Due to the influence of weather conditions such as wind, rain, ice, etc., the anti-vibration hammer of overhead transmission line wires is easy to cause corrosion and deformation of the anti-vibration hammer or the breakage of the hammer head, which affects its anti-vibration performance. Especially for old transmission lines, the service life is relatively long, and the damage of wire anti-vibration hammers has an increasing trend year by year, which makes the maintenance work of replacing and installing wire anti-vibration hammers more and more frequent.

During a power outage to replace the anti-vibration hammer for tension conductors, especially when replacing the anti-vibration hammer for single-strand conductors, since the tension insulators are installed horizontally, the distance between the anti-vibration hammer for the conductors and the cross arm is relatively far, so routinely replace and install the anti-vibration conductors The traditional methods of anti-vibration hammer mainly include parallel ladder method, soft ladder method and rope method. The parallel ladder method is that the operator fixes the parallel ladder on the cross arm and the wire, and then climbs to the position of the anti-vibration hammer to replace the wire. This method requires at least three ground assistants to be responsible for passing the parallel ladder, and two operators on the tower to cooperate. Responsible for installing and dismantling the parallel ladder and replacing the anti-vibration hammer. The entire operation procedure is very cumbersome, risky, time-consuming and labor-intensive, and the work efficiency is low. The soft ladder method is to hang a soft ladder on the wire, and the operator climbs the soft ladder to the position of the anti-vibration hammer of the wire to be replaced. The disadvantage of this method is that the operation is labor intensive, the safety factor is low, the time is long, and four ground assistants are required. The rope method is to use the rope to surround the first insulator near the conductor side, connect the conductor to the cross arm, and the operator enters the place to replace the shock hammer through the rope to replace the shock hammer. This method also has the disadvantages of high labor intensity and long time. The disadvantage of low safety factor. In general, the above three operation methods all have the problems of high risk, cumbersome procedures, high energy consumption, long time consumption and low work efficiency.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a portable anti-vibration hammer tool for replacing tension wires during power outages. Labor force, improve work efficiency.

The present invention is characterized in that it includes a main insulating tube, a universal hook on the wire side, a universal hook on the cross-arm side, a U-shaped connecting plate, and a center-through fixing bolt. The main insulating tube is provided with 4-6 secondary insulating tubes. The two ends of the main insulating pipe are connected to the U-shaped connecting plate by the through-center fixing bolt, and spring washers are installed in front of the nuts on both sides of the through-center fixing bolt; the U-shaped connecting plate at one end is connected by a nut and a spring washer The universal hook on the wire side, the lower end of the universal hook on the wire side is provided with the wire side safety wire connecting plate; The support bar is connected to the fixed splint, and the U-shaped connecting plate is connected to the universal hook on the cross-arm side through the connecting rod and the direction adjuster; Tube security line.

There are two support rod connecting plates .

The technical principle adopted in the present invention: using the principle of leverage and the stability of the triangle, after the operator hangs the universal hook on the side arm of the centipede ladder, he can easily hang the wire side hook on the wire by pressing down on one side of the centipede ladder with one foot At the same time, the staff will fix the centipede ladder firmly on the main material of the cross arm with the adjustable fixing frame (composed of support rods and fixed splints), so that the staff can safely and smoothly enter the anti-vibration hammer of the wire to be replaced through the centipede ladder It is easy to replace or install the anti-vibration hammer for tension wires, especially for the replacement of single-string anti-vibration wire for anti-vibration hammers.

The invention adopts the main insulation pipe and the secondary insulation pipe to make the centipede ladder: the insulation pipe itself is high in strength and light, and after being transformed into a climbing tool centipede ladder, it is easy to carry and transport, reduces labor intensity, and can be conveniently installed in the pipe wall The personal security line eliminates the need for operators to install personal security lines, reduces the operating process, is easy to operate, and reduces operating risks.

The present invention adopts the universal hooks on the wire side and the cross-arm side: according to the universal characteristics of the wire-side and cross-arm side universal hooks, when installing the wire-side and cross-arm side universal hooks, the operator can , different angles and orientations of the main material of the cross-arm can be freely selected, and the universal hook can be easily and effectively connected with the wire and the cross-arm, and the operation is more convenient.

The present invention adopts the spring washer and the fixing bolt through the center to fix the universal hook on the wire side and the cross arm side: the characteristic of the spring washer itself determines that it can generate elastic tension during use. When the center-through fixing bolt fixes the universal hook on the wire side and the cross-arm side on the insulating tube, install a spring washer before installing the nut on both sides of the bolt. The elastic tension generated by the spring washer can make the wire side and the cross-arm side universal hook After the hook is fixed on the insulating tube, it will not swing in any direction. At the same time, it is convenient for the operator to adjust the direction of the universal hook on the wire side and the cross arm side. The operation is simple, flexible and convenient.

The present invention adopts the universal hook on the side of the cross arm: according to the different orientations of the main material of the cross arm of the pole tower, the operator can easily adjust the direction of the universal hook on the side of the cross arm, and hang the universal hook on the side of the cross arm firmly in any direction. On the main material of the cross arm, the operator saves labor when working, and the operation is relatively simple.

The present invention adds an adjustable support rod to enhance stability: in order to enhance the stability of the centipede ladder made of insulating tubes and the universal hook on the cross arm side fixed on the cross arm, an adjustable support rod is added for fixing, so that the pole tower cross arm The main material, the universal hook on the side of the cross arm and the adjustable support rod form a triangular structure, which effectively prevents the centipede ladder from swinging left and right. In addition, the adjustable support rod can be fixed on the main material of the cross-arm of the tower in different orientations by adjusting the direction by itself, which enhances the stability of the centipede ladder, so that the operator can safely and smoothly enter the working point through the centipede ladder for operation, reducing the operation risk.

It can be seen from the above technical scheme that the present invention is safe to use, light in weight, easy to transport, carry, and install, good in stability, dexterous in use, convenient in operation, safe and reliable, reduces the labor intensity and operating risks of operators during the operation process, and improves the The work efficiency reduces the power outage time of the line, saves the cost of maintenance and construction operations, and can also be used to replace the self-explosive insulators and drain wires of the tension tower in a power outage.
