Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-scale marking line coating device used for easily drawing a marking line on a road or a parking lot. In particular, the present invention relates to an apparatus most suitable for coating small-scale lane markings of about several meters.

2. Description of the Related Art Conventionally widely used marking line coating devices are
For example, as seen in Jikaidai 4-105111 and Jikaihei 2-5412, the paint filled in the paint tanks placed on the upper part of the three-wheel or four-wheel machine is heated and kept warm by the propane gas burner below. Supply to the box type paint reservoir of
There are a pre-press type that discharges from the paint discharge port provided on the side of the machine body and a back-drawing type that has a discharge port on the four-wheel inner ring side. The latter type is poor in safety because it draws while moving backward. .

Since such a conventional structure uses propane gas as a heating source, it has a large volume and a high weight.
Moreover, he was forced to equip a cylinder of dangerous goods. Therefore, since the volume occupied by the propane gas cylinder is large, there is a limit to the increase in the volume of the paint tank when viewed from the entire marking line coating device. Further, as a difficulty at the time of use, due to its high weight, it is complicated for an operator to operate, and moreover, drawing work along the marked line prior to application requires skill. Since the four wheels pick up irregularities on the road surface, line drawing is unstable, and there are irregularities in linearity, coating thickness, and the amount of beads dispersed.

[0004] Therefore, conventionally, for the lane marking after the pavement restoration in the construction which has the underground burial work such as the pavement business, the pipe construction business, the electric construction business and the civil engineering business, the work was ordered to the line construction company. . However, the unit price of a specialist is high because it is a complete construction work, and in many cases it is not possible to carry out prompt construction, so the delivery of that construction was naturally delayed.

The inventor of the present invention has previously proposed Japanese Unexamined Patent Publication No. 8-291509 to solve the above-mentioned drawbacks, and anyone can easily and accurately perform marking line application work with a low-priced device. is suggesting. The structure is such that there are two wheels that support the machine during coating, and below the paint tank that supplies paint to the discharge port on the rear inner ring side of the two wheels. The marking line coating device was provided. The two wheels that support the machine during coating here may be only two normal wheels, but an auxiliary wheel should be provided near the paint outlet so that the wheels do not touch the ground during coating. It also includes a structure that becomes two wheels during coating, such as a structure that escapes upward.

Further, the bead discharging device comprises an outer cylinder having a discharge guide below, and a bead case of an inner cylinder rotatably provided in the outer cylinder and having a discharge port, and a handle is attached to the inner cylinder. The bead discharge operation is synchronized with the paint application by the open / close handle. Further, the paint tank is composed of a main tank on the side of the machine body and a sub tank detachably or fixedly mounted on the main tank.

In this apparatus, the heat source for heating the paint is changed from a propane gas cylinder to a lightweight butane liquefaction cylinder and its burner, so that the machine can be supported by two simple wheels during coating. The flexibility of the two-wheel axle to the ground contact surface is great, and the paint discharge port is provided on the rear inner ring side of the two wheels. With three-point support, anyone can easily and accurately draw by constructing in the front direction. And since the paint tank is composed of the main tank on the machine side and the sub tank that is detachable or fixed above it, there is a limit to the line coating (drawing) distance in the case of only the main tank,
The coating distance is extended by the sub-tank, and the coating material is added to the sub-tank, so that the line coating distance can be greatly extended in spite of the small device.

Further, the inventor of the present invention, in Japanese Unexamined Patent Publication (Kokai) No. 11-100810, examined a simple construction device for applying the liquid in a liquid-filled container from a spray gun by using the rotation of an axle as a driving force. We have proposed a construction device that can be applied even when using a liquid with a relatively high viscosity that was difficult to construct. This device is capable of accommodating and heating the liquid filling container in a paving surface spraying device in which a liquid pressurizing device is provided on a carriage, and the liquid in the liquid filling container is applied from a spray gun by the liquid pressing device. A warming device was provided on the carriage, and the warming device warmed the liquid to reduce the viscosity of the liquid without diluting it so as to improve the fluidity and to apply the liquid from a spray gun.

At present, there are an open-cut method and a propulsion method when burying pipes in the four underground burial industries, which are electricity, gas, water, and information. The latter is the mainstream. In the case of the propulsion method, the vertical shaft is dug down from the road surface, and after the installation of the propulsion unit is completed, the piping is pushed in the lateral direction.
After installing the pipes, the propulsion unit will be removed from the pit and the condition will be restored. Naturally, the pavement and lane markings on the road surface must be restored. Among the protests of this propulsion method, the conventional road surface slicing (square construction method) has a problem of excess cutting at the four corners, and circular cutting is the mainstream (for example, JP-A-6158612). In particular
When burying pipes for electricity, gas, communications, etc. of 200 mmφ or less, the diameter of the pit is about 1000 to 1500 mm, and the lane marking restoration length is 2
It is necessary to have a drawing function on a very small scale of about m. The present invention is intended to provide a small-scale marking line coating apparatus having such a function.

As a result of studying the above-mentioned problems, a machine consisting of a paint tank, a wheel provided below the machine and serving as a fulcrum at the time of drawing and supporting the machine obliquely or horizontally, and a lower part of the paint tank The paint outlet provided in
The small-scale marking line coating device includes an opening / closing operation handle connected to an opening / closing mechanism provided at the paint discharge port, a paint tank heating burner, and a fuel cylinder holder. The opening / closing mechanism provided at the paint discharge port is composed of a slide opening / closing plate for opening / closing the paint discharge port and a link for moving the slide opening / closing plate, and an opening / closing operation handle connected to the link is provided near the handle on the machine side. A structure in which a release prevention device is provided between the handle and the body side handle is preferable.

The paint tank referred to in the present invention has only to have a coating length of about 2 m so that it can be applied on a very small scale. Therefore, the paint volume can be as small as about 3 liters. The fuel cylinder to be heated is appropriately selected from disposable portable propane, butane, isobutane, etc., and these portable gas cylinders are used. It is preferable that both the opening / closing operation handle and the machine-side handle are rod-shaped handles that are projected forward in the coating direction because they are lightweight and simple. In this way, the wheels are installed under the small capacity paint tank,
Since it is a simple device that has an opening / closing mechanism and a handle at the paint discharge port, the total length is about 300 mm, the width is about 180 mm, and the weight is 5
It is a simple handy type that can be easily carried to the construction site and has never been seen before.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view of a small scale marking line coating apparatus of the present invention, FIG. 2 is a side view, and FIG. 3 is a bottom view. As is clear from these figures, the lower portion of the paint tank 1 having a capacity of 3 liters, which also serves as a machine body, is narrowed and the bottom is opened to form the paint discharge port 2. Wheels 3 are provided below the paint tank 1 to enable the progress during drawing and serve as a fulcrum to support the machine body at an inclination or a horizontal angle. A rod-shaped running handle 4 is provided so as to project from the paint tank 1 in the forward direction (indicated by an arrow in FIG. 2) during drawing. This makes it possible to proceed with drawing, maintain the inclination or horizontal angle, etc. Behind the paint tank 1, a burner 5 for heating the paint tank and a cylinder holder 6 for supplying fuel to the burner 5 are provided. The cylinder holder 6 has a gas pressure regulating valve 6a. A handle 7 is provided above the paint tank 1 to hold the inclination angle during drawing and facilitate the carrying.

An opening / closing mechanism is provided at the paint discharge port 2 below the paint tank 1. The opening / closing mechanism includes a slide opening / closing plate 8 for opening / closing the paint discharge port 2 and a link 9 for moving the slide opening / closing plate. The slide opening / closing plate 8 is a plate-like member having a width that is substantially the same as the partition line width and covers the paint discharge port 2, and the opening width can be changed by moving it in the horizontal direction (line drawing direction). . One end of a link rod 10 is pivotally supported on the side surface of the paint tank 1, and a notch 10a is provided at the other end of the link rod 10 to engage with a protrusion 8a at the end of the slide opening / closing plate 8.

The link rods 10, 10 on the left and right of the paint tank form a link together with the U-shaped bracket 11 integrated so as to straddle them, and the U-shaped bracket 11 is provided with a rod-shaped opening / closing operation handle 12. There is. As shown in Fig. 4, the opening / closing operation handle 12 connected to the link is attached to the body side handle 4
The slide opening / closing plate 8 that opens and closes the paint discharge port 2 is always biased in the closing direction because the spring 13 as an opening prevention device is provided between the two.
When an operator grips the opening / closing operation handle 12 and rotates it in the direction of the handle 4 on the machine side during drawing, the link rod 10 forming a link together with the bracket 11 rotates and the slide opening / closing plate 8 opens. Be drawn. As a result, the paint flows from the paint discharge port 2 to the road surface to draw a line. At this time, by heating the lower wall surface of the paint tank 1 by the heating burner 5, the viscosity of the paint can be reduced and the fluidity can be increased.
