Description

[Detailed description of the invention] (Field of industrial application) This invention is a live wire coating machine, especially for applying anti-rust coating to overhead line support towers and support arms of power transmission lines and trolley lines in power generation and substations and railway lines. It relates to a coating machine used for coating.

(Prior Art) When painting overhead wire support towers and support arms for power transmission lines, trolley wires, etc., conventionally the work was carried out under a power outage condition in which power transmission to the wires was stopped.

(Problem that the invention aims to solve) However, if the power transmission to the wire is stopped, it will cause a great deal of inconvenience to nearby residents and factories, and the electric power company and railway company will not only suffer losses. However, there was a problem in that the workers were forced to work quickly, causing them to become impatient and increasing the risk of falling.

In the past, there was a system in which the operator carried a tube containing the coating solution and a tube for air pressure on his back, and carried out painting work while supplying the coating solution from the tube to the brush. It was extremely dangerous to work at heights, which required carrying a heavy weight on one's back, which restricted the movement of the body and required to be nimble.

(Means for solving the problems) The present invention was devised to solve the problems of the prior art, and its purpose is to:
Our objective is to provide a coating machine that is easy to handle so that work can be carried out safely even when the power is being transmitted to a live wire.As a technical means to achieve this purpose, we have developed a handle 1 made of an insulated rod; and an arm 4. Brush 5 on the tip of

A receiving surface 1 formed at the base end surface of the handle 1 and at the tip end of the handle 1.
a nozzle 25 connected to the other end of an outflow hose 26 made of a flexible hose inserted into a gap 17 formed between the brush 5 and the brush 5; The base end surface of the arm 4 of the brush member 3 is formed as a cam surface 15 with the pivot point as a fulcrum, and the receiving surface 1
6 is formed at a position facing the cam surface 15, and when the cam surface 15 positions the brush member 3 in a straight-extending state by the click mechanism 6, the cam surface 15 and the receiving surface 16 connect the outflow hose. 26 is compressed flat to close the conduit 27, and when the brush member 3 is positioned in a bent state by the click mechanism 6, the conduit 27 of the outflow hose 26 is opened. It was decided to.

(Function) Therefore, since the live wire coating machine of the present invention is provided with a handle made of an insulated rod, work can be carried out safely at a position away from the dangerous area by the length of the handle. The brush member is provided so as to be bendable relative to the handle via a click mechanism, and
The coating liquid can be supplied and stopped using the rotation of the cam surface that accompanies the direct extension operation, so simply strike the brush member against a steel frame, etc., bend the brush member toward the handle, and make it extend directly. The coating solution can be supplied and stopped automatically, eliminating the need for troublesome operations such as opening and closing valves, making it easier to handle.

(Example) Hereinafter, a live wire coating machine A which is an example of the present invention will be described with reference to the drawings.

Reference numeral 3 denotes a brush member, and a brush 5 is provided at the tip of an arm 4, and the base end of the arm 4 is pivotably attached to the tip of the handle 1 via a click mechanism 6 so as to be bendable.

In this case, a plate 7 is fixed to one side of the tip of the handle 1, a mounting hole 8 is formed at the tip of the plate 7, and a mounting hole 8 is formed on the inner surface of the plate 7 on the same radius around the mounting hole 8. Ball head pins 9 are embedded with their heads protruding at regular intervals of 90 degrees, and mounting holes 10 are also formed at the base end of the arm 4 in the brush member 3, and mounting holes are formed on the inner surface. Hemispherical recesses 11 that fit into the spherical pin 9 are formed at equal intervals of 30° on the same radius centered at 10, and
Insert the pivot pin 12 with the mounting holes 8 and 10 aligned, and fit the spring 14 between the adjustment nut 13 screwed onto the tip of the pivot pin 12 and the plate 7. The plate material 7 and the arm 4 are connected by the spring 14.
The mounting structure is such that the two sides are biased in the facing direction. Then, the above-mentioned ball head pin 9 and hemispherical recess 1
1 and a spring 14.
The brush member 3 can be placed in a straight-extending state (FIG. 2) in which it extends in the same direction as the handle 1, and in a straight-extending state (see FIG.
The state of refraction at every 30° extending in the direction of refraction with respect to the direction of extension of (Figure 3 shows the state of refraction at 90°),
It is now positioned at

Further, the proximal end surface of the arm 4 is formed into a cam surface 15 whose distance from the pivot pin 12 is gradually changed;
Further, a receiving surface 16 opposite to the cam surface 15 is provided at the tip of the handle 1, and the receiving surface 16 and the cam surface 1
An outflow hose, which will be described later, is inserted into the gap 17 between the pipe and the pipe 5.

The cam surface 15 is configured such that when the arm 4 of the brush member 3 is positioned in a straight-extending state by the click mechanism 6,
The outflow hose 2 is connected to the cam surface 15 and the receiving surface 16.
6 is compressed flat to close the conduit 27, and
When the arm 4 of the brush member 3 is positioned in the bent state by the click mechanism 6, the outflow hose 26
It is formed in a shape that opens the conduit 27.

Next, 18 is a cylinder, which is attached to the handle 1 by a band 19, has an inlet 20 and an outlet 21 on one end surface, and has a piston inside that is biased by a spring. ing.

22 is a coating liquid tank, and an outflow hose 23 formed of a flexible hose is connected to the inlet 20 of the cylinder 18.
A hook 24 is provided on the top surface.

Further, 25 is a nozzle, which is installed inside the brush 5 and has an outflow hose 26 made of a flexible hose.
The outlet port 21 of the cylinder 18 is connected to the outlet port 21 of the cylinder 18 through the outlet port 21 of the cylinder 18.

The outflow hose 26 is connected to the cam surface 1 described above.
The outflow hose 26 is connected to the cam surface 15 and the receiving surface 16 with the brush member 3 positioned in a straight line as shown in FIG. The conduit 27 is closed by compressing it flat, and in the bent state of 30 degrees, the conduit 27 is
is opened by 1/3, and in the bent state of 60°, pipe 27 is opened by 2/3.
When open and bent at 90° as shown in Figure 3, pipe 2
I try to open the 7 all the way. In addition, 28 is a presser plate.

Therefore, when using the coating machine A of this embodiment, the coating liquid tank 22 containing the coating liquid is hung by hooking the hook 24 to the arm 29 or the like at a position higher than the area to be coated. When the tank 30 of the tank 22 is opened, the coating liquid flows into the cylinder 18 from the inflow hose 23 due to potential energy, and further flows from the cylinder 18 through the outflow hose 26 to the nozzle 2 installed inside the brush 5.
In this case, when the brush member 3 is positioned in a straight line with respect to the handle 1, the cam surface 15 and the receiving surface 16 close the conduit 27 of the outflow hose 26. Because of this, the supply of coating fluid will be stopped. Therefore,
During actual application work, the operator, while gripping the handle 1, breaks the arm 4 of the brush member 3 against a steel frame, etc., and changes the brush member 3 from a straight state to a bent state via the click mechanism 6. By bending it, the conduit 27 of the outflow hose 26 is opened and the coating liquid can be supplied to the brush 5, and the operator can
is gripped and the coating liquid is applied to the surface to be coated using the brush 5.

In addition, the amount of supply of the coating liquid can be adjusted by changing the bending angle of the brush member 3, and the supply of the coating liquid can be stopped by positioning the brush member 3 in a straight-extending state.

Also, when the coating liquid in the tank 22 becomes small, the pressure decreases and the discharging of the coating liquid becomes difficult.In this case, the piston of the cylinder 18 is pulled by the trigger 31, and the coating liquid is sucked into the cylinder. This is then sent out from the outlet 21 by the pressure of the spring.

Although one embodiment of the present invention has been described above with reference to the drawings, the specific configuration of the present invention is not limited to the above-described embodiment.

For example, the material of the handle is not limited as long as it is an insulating rod, and it may be made of wood such as oak.The length can also be determined as appropriate, and it is more preferable if the handle is telescopic.

Also, regarding the click mechanism, the ball head pin may be directly biased by a spring, or a steel ball may be used instead of the ball head pin.

Further, in the embodiment, the bending angle of the brush member can be adjusted in 30° increments, but it is within the scope of the present invention as long as it can be positioned in at least two positions, a straight-extending state and a constant bending state.

(Effects of the invention) As explained above, according to the invention, since the handle is provided with an insulating rod, it is possible to be as far away from the dangerous area as the handle is, and the supply and stop of the coating liquid can be controlled by the brush member. Since the operation is simply to bend and straighten the valve, there is no need for the troublesome work of operating a valve, making it easier to handle. Since this is a particularly dangerous work, ease of handling is the most important requirement, and the present invention satisfies this requirement and can be used practically.
