Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air compressor, and more particularly, to an air compressor with a small accumulator tank that is portable with a hose winder and uses the accumulator tank as a hose winding drum.

[0002]

2. Description of the Related Art Conventionally, there is no such an air compressor, and a hose winder around which an air hose is wound is separately prepared and used by connecting to the air compressor.

[0003]

Such an air compressor is often used by a painter mainly at a construction site, and it is loaded on a wagon or a light van to go to the site. At this time, since the air compressor and the hose winder are separate, a lot of loading space was required, which hindered loading of other work tools.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to integrate an air compressor and a hose winder into a conventional hose winding device. It is to provide an air compressor that does not require a machine and can save the loading space.

[0005]

In order to achieve the above-mentioned object, the technical means taken by the present invention is that the both ends of the accumulator tank of the air compressor with the accumulator tank are rotatably installed on the frame, and one side is provided. The end part and the discharge part of the air compressor are connected by connecting means, flanges are provided on the left and right side surfaces of the accumulator tank, and hose connecting means is provided on the outer peripheral surface of the tank sandwiched between both flanges to wind the outer peripheral surface of the tank with a hose. It is characterized by the fact that it is taken as a part.

The pressure accumulating tank has a substantially cylindrical shape with spherical surfaces on both sides, and is provided with spindles at both ends. One of the support shafts is a hollow shaft, which circulates inside and outside the accumulator tank. The frame is made of steel pipe, etc., and has a substantially cubic shape.
The air compressor is fixed, and the shaft support of the accumulator tank is provided. Although the air compressor and the accumulator tank are installed side by side in parallel with each other in a plan view, the accumulator tank may be installed directly above the air compressor.

As the connecting means, a rotary joint or the like is provided at the tip of the hollow shaft, and a steel pipe or a hose is connected to the discharge port of the air compressor. Also, the flanges on the left and right side of the accumulator tank are welded to the outer peripheral surface of the accumulator tank, and its height is
3 to 4 times the diameter of the hose. Then, the hose connecting means is provided with an inverted L on the outer peripheral surface of the accumulator tank sandwiched by both flanges.
A character-shaped pipe is provided, communicated with the inside of the accumulator tank, and a hose joint is attached to the tip thereof.

The hose winding portion constituted by the outer peripheral surface of the pressure accumulating tank has a flat surface, but a chord winding groove may be provided to make the hose winding beautiful.

[0009]

According to the above means, since the pressure accumulating tank has both ends rotatably mounted on the frame, it can freely rotate. Then, the air discharged from the air compressor can be accumulated by the connecting means. Furthermore, if you connect a hose to the hose connection means,
This can be wound around the outer peripheral surface of the accumulator tank, and the accumulator tank functions as a winding cylinder of the hose winder. Therefore, the conventional hose winder becomes unnecessary.

Further, if the air compressor and the accumulator tank are arranged parallel to each other in plan view, stability at the time of installation can be obtained.
Placing the accumulator tank directly above the air compressor makes it easier to handle the hose.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. An air compressor 1 with a pressure accumulating tank is composed of a pressure accumulating tank 3 having a hose winding portion in a substantially cubic frame 2 formed of a steel pipe, shaft supporting portions 4a and 4b rotatably supporting the accumulating tank 3, an engine or a motor. A compressor and an air compressor 5 having an integrated operation unit are installed in parallel, and a connecting means 6 for connecting the accumulator tank 3 and the air compressor 5 is provided. (See Fig. 1)

The above-mentioned pressure accumulating tank 3 is made of a steel pipe or a steel plate in a cylindrical shape, and both side surfaces 7a and 7b thereof are spherical so as to disperse the internal pressure, and a shaft 8 is provided at the center thereof.
a and 8b are attached. At both ends, flanges 9a and 9b are provided to prevent the wound hose from collapsing to the outside of the accumulator tank. The height of the flange is 3 to 4 times the diameter of the hose, that is, the height at which the hose can be wound in 3 to 4 layers. An elbow 11 is attached to the outer peripheral surface 10 between the two flanges to circulate the inside and outside of the accumulator tank 3, and a hose joint 12 is attached to the tip thereof.

The shaft 8a is a hollow shaft which circulates between the inside and the outside of the pressure accumulating tank 3, and a rotary joint 13 is attached to the tip thereof. On the other hand, a handle 14 for rotating the accumulator tank 3 is provided at the tip of the shaft 8b.
Is attached. Further, the frame 2 is basically formed by assembling a steel pipe into a rectangular frame shape and bending both sides thereof vertically. The air compressor 5 is fixed in about half the space, the shaft support portions 4a, 4b are provided in the remaining space, and the accumulator tank 3 is rotatably installed.

In the connecting means between the pressure accumulating tank and the air compressor, the rotary joint 13 attached to the end of the hollow shaft 8a of the pressure accumulating tank and the discharge port 15 of the air compressor are connected by a steel pipe or a hose.

Next, a method of using the above-mentioned first embodiment will be described. A hose 16 is connected to a joint 12 at the tip of an elbow 11 attached to the outer peripheral surface of the pressure accumulating tank 3, and a spray gun or the like is attached to the tip thereof. Then, by turning the handle, the hose 16 can be wound around the outer peripheral surface of the accumulator tank 3. In this state, it can be loaded on the trunk of a wagon or light van and headed to the site. When it arrives at the site, the hose 16 can be pulled out, and the air compressor can be used for painting work. Although the air compressor section and the accumulator tank section are installed in parallel in the drawing, for the purpose of the present invention, the air compressor section and the accumulator tank section may of course be arranged vertically.

[0016]

According to the air compressor with a pressure accumulating tank of the present invention, since the pressure accumulating tank also functions as the hose winding portion, it is not necessary to separately prepare a hose winding machine. Therefore, the space for one hose winder can be saved when it is loaded on the vehicle, and thus other tools can be loaded accordingly. Also, in the field,
Connection work with the hose winder is not necessary, so work can be started quickly and post-cleanup can be completed quickly.

Further, in the case of the structure described in claim 2, since the air compressor part and the accumulator tank part are installed in parallel with the frame, the ground contact area becomes large. Therefore, there is no fear of falling due to vibration even when loaded on a vehicle, and stability when installed at a work site is also good. Further, in the case of the configuration described in claim 3, the position of the pressure accumulating tank portion is higher than in the case of claim 2, so that the handling work of the hose becomes easier. Further, since the heavy air compressor section is located at the bottom, stability is not impaired.
