Description

Spraying device and spraying method {SPRAY APPARATUS AND SPRAY METHOD}

The present invention relates to a spraying device and a spraying method, and more particularly, to an spraying device and a spraying method capable of suppressing the influence of the spraying pressure.

Materials used in the steel mill, such as coal, are transported by a conveyor belt to a yard for molten iron production or a yard. And, while the material is being loaded and moved on the conveyor belt, a large amount of dust is generated by the material, and the material falling to the floor of the workshop where the conveyor belt is installed may be generated. Accordingly, since the floor of the workshop where the conveyor belt is installed is contaminated by dust and camel, cleaning is required.

For cleaning, use a spraying facility equipped with a spray gun that sprays water on the floor of the workplace. That is, water is sprayed onto the floor of the workshop through the spray gun to clean. This spraying facility is installed to connect a fixed pipe connected to a water tank for providing water, a spray gun for spraying water, and a fixed pipe and a spray gun, and a moving pipe that rotates around the fixed pipe so that the horizontal position is adjusted. includes

The spray gun is provided to be movable so as to spray water to the spray target position. That is, the spray gun is provided to be rotatable around one end so that the horizontal position thereof is changed.

However, when the current position of the injection gun and the injection target position are far away, it is difficult to adjust the injection gun to face the injection target position only by rotating the injection gun. Accordingly, a moving pipe connecting between the fixed pipe and the spray gun is provided so as to be able to rotate around the fixed pipe. That is, the moving pipe may be rotated around the fixed pipe in a state connected to the fixed pipe, whereby the horizontal position of the moving pipe and the spray gun is changed.

On the other hand, when water is sprayed from the spray gun, a repulsive force is generated by the spraying pressure, and the repulsive force acts in a direction opposite to the spraying direction. That is, the repulsive force due to the injection pressure is transmitted to the moving pipe, whereby the moving pipe can rotate around the fixed pipe.

In addition, water is injected at a high pressure according to the injection target position and the injection purpose, and as the injection pressure increases, the repulsive force increases. Accordingly, when the spray is sprayed at high pressure, the moving pipe may be strongly rotated around the fixed pipe by the repulsive force generated at this time. In this way, when the moving pipe moves by the spray pressure while spraying water from the spray gun, a safety accident in which the surrounding equipment is damaged or the operator is exposed to danger may occur.

That is, the support body 1222 is installed to connect between the injection unit 1221 and the moving pipe unit 1210 or between the driving member 1223 and the moving pipe unit 1210 . In addition, the inside of the support body 1222 may communicate with the moving pipe unit 1210 , the driving member 1223 and the injection unit 1221 , and a passage through which the injection material can move is provided. That is, a passage through which the spray can move is provided in the support body 1222 , one end of which communicates with the moving pipe unit 1210 , and the other end communicates with the inlet of the spray unit 1221 . In this case, the other end of the support body 1222 may be in direct communication with the inlet of the injection unit 1221 or may be in communication with the driving member 1223 .

The support body 1222 is connected to the moving pipe part 1210 to be rotatable. More specifically, the support body 1222 is formed to extend in the vertical direction, and can be rotated by an external force about a center in a width direction or a diameter direction intersecting the extension direction as an axis.

At this time, the passage in the support member 1222b communicates with the passage of each of the moving piping unit 1210 and the holding member 1222a. And, the passage of the holding member 1222a communicates with the support member 1222b and the injector 1220 . In this case, the holding member 1222a may be in direct communication with the injection unit 1221 or may be indirectly communicated through the driving member 1223 .

In addition, a means for enabling rotation of the support body 1222 may be installed at the connection portion between the support body 1222 and the moving pipe part 1210 , and well-known means may be used.

The means for connecting the support body 1222 and the moving pipe part 1210 so that the support body 1222 is rotatable is not limited to the above-described rolling bearing, and is supported by an external force while connected to the moving pipe part 1210 . Any means may be used as long as the body 1222 is rotatable means.

In this way, the support body 1222 supporting the injection unit 1221 can be rotated about the center in the width direction or the radial direction by an external force. That is, when a force is applied to the injector 1220, the support body 1222 rotates, and accordingly, the entire injector 1220 rotates. At this time, the injector 1220 may be rotated by applying a force to the injector 1220 in a clockwise or counterclockwise direction.

In applying a force to the injector 1220 so that the injector 1220 is rotated in this way, the operator can apply the force by grasping at least one of the holding member 1222a of the support body 1222 and the lever 1224 to be described later. have.

More specifically, the driving member 1223 is fastened to the upper portion of the support body 1222 so as to be rotatable in the front in which the injection hole 1221a is located and in the rear direction opposite to the injection hole 1221a with respect to the support body 1222 . do. At this time, the driving member 1223 may be fastened to the upper portion of the holding member 1222a of the support body 1222 . In addition, both ends of the driving member 1223 in a direction crossing or orthogonal to the extending direction of the injection unit 1221 may be fastened to the holding member 1222a so as to be rotatable forward or backward in response to an external force.

When the driving member 1223 rotates forward or backward by an external force, the injection unit 1221 connected thereto moves vertically or ascends and descends. That is, as the injection unit 1221 connected to the driving member 1223 rotates around one end thereof, the other end, that is, the injection port 1221a elevates and descends so that the height of the injection hole 1221a changes. In this way, the inclination or angle of the spraying part 1221 can be adjusted by the operation of elevating the spraying part 1221 so that the height of the spraying hole 1221a is changed. That is, by adjusting the angle between the spraying unit 1221 and the floor of the workplace where the spray is to be sprayed, the spraying angle of the spray can be adjusted.

The lever 1224 may be provided so that the operator can handle it by grasping it by hand. For example, the lever 1224 may have a bar shape extending in one direction, and may be connected to the driving member 1223 to be positioned opposite to the injection unit 1221 . That is, the lever 1224 may have a shape extending from the driving member 1223 to the opposite side of the injection unit 1221 .

That is, the moving pipe 1211 communicates with the passage of each of the fixed piping unit 1100 and the injector 1220 therein, and has a passage through which the spray can move. And, among both ends of the passage, one end connected to the fixed pipe unit 1100 and the other end connected to the injector 1220 are opened. Accordingly, the spray provided from the fixed pipe unit 1100 is introduced through one end of the moving pipe 1211 , and then is discharged through the other end and supplied to the injector 1220 .

In addition, the moving pipe 1211 is provided to be able to rotate around the fixed pipe part 1100 so that its horizontal position is changed.

The pipe 1211b and the first connecting pipe 1211a and the second connecting pipe 1211b are connected, and may include an intermediate pipe 1211c in which the moving member 1212 is installed. Here, the first connecting pipe 1211a, the intermediate pipe 1211c, and the second connecting pipe 1211b may be provided integrally.

In addition, the moving pipe 1211 is a connecting member (rotational connecting member 1211d) connecting between the joint 1300 and the first connecting pipe 1211a so as to be rotatably connected to the joint 1300 (rotational connecting member 1211d) and an injector ( and a valve 1211e for controlling communication with 1220.

The first connection pipe 1211a is formed to extend in the arranging direction of the joint portion 1300 and the rotation connection member 1211d, and one end is connected to the rotation connection member 1211d connected to the joint portion 1300, and the other end is the middle It is connected to the pipe 1211c. At this time, since the joint 1300 is connected to the fixed connecting member 1120, the first connecting pipe 1211a is connected to the fixed connecting member 1120 through the rotating connecting member 1211d and the joint 1300. can be explained. Also, the movable pipe unit 1210 may be described as rotating around the fixed pipe unit 1100 , that is, the fixed connecting member 1120 .

The rotation connection member 1211d connects between the joint part 1300 and the first connection pipe 1211a, and may be rotated while being connected to the joint part 1300 . That is, the rotation connecting member 1211d is to be fastened to the joint 1300 so as to be rotatable about the center in the width or diameter direction intersecting the arrangement direction of the joint 1300 and the first connecting pipe 1211a as an axis. can The rotation of the rotation connecting member 1211d will be described again when the joint 1300 is described later.

A first connection pipe 1211a is connected to the rotation connection member 1211d, and the first connection pipe 1211a is connected to be fixed to the rotation connection member 1211d. That is, the first connection pipe 1211a is installed to be fixed to the rotation connection member 1211d so as not to rotate separately from the rotation connection member 1211d.

And, the rotation connecting member (1211d) is provided to have a passage communicating with each passage of the joint portion 1300 and the first connection pipe (1211a). Accordingly, the spray passing through the joint 1300 may be moved to the first connection pipe 1211a through the rotation connection member 1211d.

One end of the second connecting pipe 1211b is connected to the intermediate pipe 1211c, and the other end is connected to the support body 1222 of the injector 1220 . Accordingly, the injection material provided from the intermediate pipe 1211c may be moved to the support body 1222 of the injector 1220 via the second connection pipe 1211b. The shape of the second connection pipe 1211b is not particularly limited, but may be, for example, a shape extending in the vertical direction or perpendicular to the floor surface of the workshop.

The intermediate pipe 1211c is a pipe connecting the first connecting pipe 1211a and the second connecting pipe 1211b. That is, one end of the intermediate pipe 1211c in the extending direction is connected to the first connection pipe 1211a, and the other end is connected to the second connection pipe 1211b. Accordingly, the spray provided from the first connection pipe 1211a may be moved to the second connection pipe 1211b through the intermediate pipe 1211c. And, it is preferable that the intermediate pipe 1211c has at least a shape extending in a direction crossing or orthogonal to the first connection pipe 1211a connected to the rotation connection member 1211d. To explain with a more specific example, the first connection pipe 1211a may have a shape extending in the vertical direction to be perpendicular or perpendicular to the floor of the workshop, and the intermediate pipe 1211c may have a shape extending to be parallel to the floor of the workshop. .

The valve 1211e controls communication between the moving pipe 1211 and the injector 1220 , that is, the moving pipe 1211 and the support body 1222 . The installation position of the valve 1211e is not particularly limited, but may be installed, for example, on an extension path of the second connection pipe 1211b. In addition, the valve 1211e may be, for example, a ball valve, but is not limited thereto, and any valve may be applied as long as it is a means capable of controlling communication between the moving pipe 1211 and the injector 1220 .

The moving member 1212 is installed to support the intermediate pipe 1211c while being drivable by an external force. The moving member 1212 may be a driving means so that the moving pipe 1210 can be moved in a direction crossing or orthogonal to the extending direction of the intermediate pipe 1211c. As a more specific example, the moving member 1212 may be a means including a rotatable wheel. And the wheel may be provided to rotate in a direction crossing the extension direction of the intermediate pipe (1211c) or in a radial direction of the intermediate pipe (1211c).

Of course, the moving member 1212 is not limited to means including wheels as described above, and may be means including various means, for example, rails. In this case, the rail may have a shape extending in a direction crossing or orthogonal to the extending direction of the intermediate pipe 1211c.

That is, the joint 1300 may be a means including a rolling bearing including an inner ring connected to the fixed connection member 1120, an outer ring connected to the rotation connection member 1211d, and a ball positioned between the inner ring and the outer ring. According to such a joint 1300, the outer ring rotates by the external force transmitted through the rotation connection member 1211d, and the rotation connection member 1211d mounted on the outer ring rotates. And with the rotation of the rotation connecting member 1211d, the moving pipe 1211 connected thereto rotates together.

The joint 1300 is not limited to the means including the above-described rolling bearing, and any means may be used as long as it is a means for enabling the rotation connection member 1211d to be rotatable by an external force in a connected state.

Hereinafter, the movement of the injector 1200 will be described.

The direction in which the other end of the injection unit, that is, the injection hole 1221a, looks, needs to be changed according to the target position at which the injection material is to be injected (hereinafter, the injection target position). That is, the injection port 1221a should face the injection target position or face the injection target position, and for this purpose, the injection unit 1221 is moved to adjust its position.

For example, the support body 1222 is rotated to adjust the horizontal position of the injection part 1221 or the injection hole 1221a. As another example, by rotating the driving member 1223, the injector 1220 is rotated with one end connected to the driving member 1223 as an axis. Accordingly, the height of the injection port 1221a rises or falls. Through the movement of the injection unit 1221 as described above, the injection hole 1221a may face the injection target position or may face the injection target position.

On the other hand, as the current position of the injection hole and the injection target position are farther away, it may be difficult to match the injection target position only by the rotation of the support body 1222 and the raising/lowering operation of the injection unit 1221 . This is because the support body 1222 only rotates (ie, rotates) about the center in the width direction or the diameter direction as an axis, so the horizontal position change amount of the injection unit 1221 due to the rotation of the support body 1222 Because this is limited. In addition, only the height of the injection hole 1221a can be adjusted by the rotation of the driving member 1223 and the horizontal position cannot be adjusted.

Accordingly, when the injection port 1221a cannot be directed toward the injection target position only by the rotation of the support body 1222 and the elevating operation of the injection unit 1221, the entire injection device 1200 is moved. That is, by rotating the moving pipe unit 1210 around the fixed pipe unit 1100 , for example, the horizontal position of the moving pipe unit 1210 and the injector 1220 is adjusted as shown in FIG. 2 .

To this end, a force is applied to the injection device 1200 so that the moving pipe part 1210 can be rotated around the fixed pipe part 1100 . At this time, depending on the direction in which the force is applied, the rotating connecting member 1211d connected to the joint 1300 rotates clockwise or counterclockwise, and the rotating force of the rotating connecting member 1211d is the entire moving pipe 1211. is transmitted to Accordingly, the moving member 1212 connected to the moving pipe 1211 operates.

By the rotation of the rotation connecting member 1211d and the operation of the moving member 1212 , the entire moving pipe 1211 rotates around the fixed pipe unit 1100 . In other words, the moving pipe 1211 rotates around one end connected to the joint 1300 .

At this time, the fixed connecting member 1120 and the rotating connecting member 1211d formed to extend in the serial direction of the joint 1300 and connected to the joint 1300 is connected to the joint 1300 and rotates on the spot. rotate motion. Accordingly, the horizontal position of the rotation connecting member 1211d may be fixed. In addition, the first connection pipe 1211a that is formed to extend in the serial direction of the joint 1300 and the rotation connection member 1211d and is connected to the rotation connection member 1211d to be fixed to the rotation connection member 1211d is connected to the rotation connection member 1211d. to make a rotational motion that rotates on the spot. Accordingly, the horizontal position of the first connection pipe 1211a may be fixed.

In addition, the intermediate pipe 1211c extending in a direction crossing or perpendicular to the extending direction of the first connecting pipe 1211a moves so as to change its horizontal position by the rotation of the first connecting pipe 1211a. In other words, the intermediate pipe 1211c rotates about the fixed pipe part 1100 or the first connection pipe 1211a. Accordingly, the horizontal position of the intermediate pipe 1211c is changed, and this causes the second connection pipe 1211b connected to the intermediate pipe 1211c and the injector 1220 connected to the second connection pipe 1211b to change the horizontal position. move as much as possible

In this way, as the moving pipe unit 1210 is provided to be able to rotate and move around the fixed pipe unit 1100 , it is possible to move the entire injection device 1200 . Accordingly, even if the distance between the current location of the injection hole 1221a and the injection target position is long, by rotating the moving pipe unit 1210, the injection hole 1221a can be adjusted to face the injection target position.

On the other hand, when the spray material is injected from the injector 1220, a repulsive force is generated by the injection pressure, and the repulsive force acts in a direction opposite to the direction in which the spray material is sprayed (refer to FIG. 1). That is, an impact may be applied to the moving pipe unit 1210 connected to the injector 1220 by the repulsive force caused by the injection pressure.

And, the spraying material is injected at a high pressure according to the injection target position and the injection purpose, and as the injection pressure increases, the repulsive force increases. Accordingly, when spraying the spray at high pressure, the entire spraying device 1200 may be strongly rotated around the fixed pipe unit 1100 by the repulsive force generated at this time. That is, the moving pipe unit 1210 may rotate around the fixed pipe unit 1100 by the repulsive force caused by the injection pressure (refer to the dotted arrow in FIG. 1 ). And due to this, the injector 1220 connected to the moving pipe unit 1210 also rotates and moves, and eventually the injector 1200 as a whole may move.

Immediately after starting or during the injection of the injection, if the moving pipe unit 1210 or the injection device 1200 as a whole moves by the injection pressure, the equipment around the injection device 1200 may be damaged, or the operator may be at risk. Exposure to safety accidents may occur. Accordingly, in order to prevent the movement of the moving pipe unit 1210 while the spray is sprayed, the operator may perform the spraying operation while holding the spraying device 1200 , but since the operator is fixing the spraying device 1200 , is limited and requires a lot of power.

Accordingly, the present invention provides an injector 1200 having a fixture 1230 capable of preventing or suppressing movement of the injector 1200 by the injection pressure. More specifically, there is provided an injection device having a fixing device 1230 capable of preventing or suppressing rotational movement of the moving pipe portion 1210 by injection pressure.

Hereinafter, with reference to FIGS. 3 to 5, an injection facility having a fixture according to an embodiment of the present invention will be described.

3 is an exploded perspective view for explaining a fixture according to an embodiment of the present invention. 4 and 5 are diagrams illustrating an operation of a fixture according to an embodiment of the present invention. Here, FIG. 4 is a state in which the fixing part is not inserted into the through hole of the rotating flange, and FIG. 5 is an inserted state.

3 to 5, the fixture 1230 is mounted and fixed to the moving pipe 1211 so as to be rotatable together with the moving pipe 1211, and a rotating flange having a hole (hereinafter, a through hole 1232a). It is connected to be fixed to the 1232 and the fixed pipe portion 1100 , and includes a fixed portion 1231 that is capable of being coupled to and separated from the rotating flange 1232 . In addition, the fixing unit 1230 may include a fixing flange 1233 fixed to the fixing pipe unit 1100 and a coupling part 1234 for coupling the fixing part 1231 to the fixing flange 1233 .

The rotation flange 1232 is installed on the rotatable movable pipe 1211 , and may be installed to surround the outer circumferential surface of the movable pipe 1211 . More specifically, the rotation flange 1232 may have a hollow shape in which an empty space is provided in the center so that the first connection pipe 1211a can pass therethrough. And, when the first connection pipe 1211a is passed through the empty space in the center of the rotation flange 1232 , the rotation flange 1232 is installed to surround the outer circumferential surface of the first connection pipe 1211a. At this time, the rotation flange 1232 is coupled or fixed to the first connection pipe 1211a so as not to move separately from the first connection pipe 1211a. For example, the rotation flange 1232 and the first connection pipe 1211a are coupled using a separate coupling means, or coupled by a bonding method such as welding.

In addition, a through hole 1232a is provided in the rotation flange 1232 , and is provided to pass through the rotation flange 1232 in the extending direction of the fixing part 1231 . That is, the through hole 1232a is provided to penetrate the rotation flange 1232 in the vertical direction or the thickness direction. A plurality of through-holes 1232a are provided, and the plurality of through-holes 1232a are arranged in a rotation direction of the rotation flange 1232 or the first connection pipe 1211a. For example, eight through-holes 1232a may be provided, and the eight through-holes 1232a are arranged at equal intervals in the rotational direction of the rotating flange 1232 or the first connecting pipe 1211a. Of course, the number of through-holes 1232a is not limited to the above-described example of eight, and may be less or more than eight.

In the above, it has been described that the rotation flange 1232 is installed on the first connection pipe 1211a of the moving pipe 1211 . However, the present invention is not limited thereto, and may be connected to the rotation connecting member 1211d of the moving pipe 1211 .

The fixing part 1231 includes a fixing member 1231a that can be engaged and separated from the rotation flange 1232 so that a part can be inserted into or taken out of the through hole 1232a provided in the rotation flange 1232 . .

In addition, the fixing part 1231 is located on the upper side of the fixing member 1231a, one end is connected to the fixing pipe part 1100, and a guide member ( 1231b), one end is connected to the guide member 1231b and the other end is connected to the fixing member 1231a, so that the fixing member 1231a can be moved up and down by an external force, and the elastic part 1231c having elasticity. ) is included.

In addition, the fixing part 1231 may include an operation member 1231d which is formed to extend outwardly from the fixing member 1231a and is provided so that the operator can grasp it by hand.

The fixing member 1231a is fastened with the rotating flange 1232 to block the rotation of the rotating flange 1232 or the first connecting pipe 1211a, or the rotating flange 1232 or the first connecting pipe 1211a is rotated. It is a means separable from the rotating flange 1232 as possible. The fixing member 1231a may have a shape extending toward the rotation flange 1232 so as to be coupled to and separated from the rotation flange 1232 . In other words, the fixing member 1231a may have a shape extending in the arrangement direction of the fixed pipe part 1100 and the moving pipe 1211 or the fixed pipe part 1100 and the rotating flange 1232 . In other words, the fixing member 1231a may have a shape extending in the vertical direction.

The fixing member 1231a is provided so as to be able to move up and down by an external force, and at least a part thereof is provided to be raised and lowered while being inserted into the guide member 1231b. To this end, the fixing member 1231a may be inserted such that at least one end thereof is positioned inside the guide member 1231b. And, the other end is located above the rotation flange 1232 or the through hole 1232a provided in the rotation flange 1232 according to the movement of the fixing member 1231a, or through the through hole 1232a. The through hole 12132a may be positioned to protrude inside or below the through hole 12132a.

In locating the other end of the fixing member 1231a above the rotation flange 1232 or the through hole 1232a provided in the rotation flange 1232 , the other end of the fixing member 1231a is the upper portion of the rotation flange 1232 . It is desirable not to come into contact with the surface. In other words, it is preferable that the other end of the fixing member 1231a be spaced apart from the upper side of the upper surface of the rotating flange 1232 .

When the other end of the fixing member 1231a passes through the through-hole 1232a and is located inside the through-hole 1232a or protrudes downward of the through-hole 1232a, the moving pipe part ( 1231a) by the fixing member (1231a) 1210) cannot be rotated. This is because the fixing member 1231a is fastened to the through hole 1232a of the rotation flange 1232 so that the rotation flange 1232 installed on the first connection pipe 1211a is fixed without being rotated. Conversely, when the other end of the fixing member 1231a is positioned above the through hole 1232a or the rotating flange 1232 , the moving pipe unit 1210 may rotate around the fixed pipe unit 1100 . That is, the rotation connection member 1211d and the first connection pipe 1211a may be rotated by an external force. This is because the fixing member 1231a is separated from the rotation flange 1232 installed in the first connection pipe 1211a, and there is no force to block the rotational force of the rotation flange 1232 .

It is effective that the other end of the fixing member 1231a passing through the through hole 1232a of the rotation flange 1232 is provided in a shape in which the width or diameter decreases toward the lower end. In this case, it may be easier for the other end of the fixing member 1231a to pass through the through hole 1232a. In addition, it is more effective that the other end of the fixing member 1231a is provided in a shape having a convex curved surface in the downward direction as in the enlarged view shown in FIG. 3 . In this case, when one end of the fixing member 1231a is provided to have a curved surface, passage through the through hole 1232a becomes easier compared to the case where the fixing member 1231a has a sharp edge.

In the above description, it has been described that the fixing unit 1230 includes a rotating flange 1232 , and the fixing member 1231a is fastened or connected to the moving pipe unit 1210 through the rotating flange 1232 . That is, by penetrating the other end of the fixing member 1231a through the through hole 1232a provided in the rotation flange 1232 , the fixing member 1231a is indirectly connected to the moving pipe unit 1210 through the rotation flange 1232 , or connection has been described.

However, the fixing unit 1230 may not include the rotating flange 1232 , and the fixing member 1231a may be provided to be directly connected to the moving pipe unit 1210 . For example, the other end of the fixing member 1231a may be provided with a means capable of being fastened to and separated from the moving pipe unit 1210 , such as a clamp or tongs.

The guide member 1231b is positioned above the fixing member 1231a and has one end fixedly connected to the fixing pipe unit 1100 . The guide member 1231b may have a shape extending in the extending direction of the fixing member 1231a, and an empty space extending in the extending direction of the guide member 1231b, that is, a guide passage is provided therein. In addition, the guide member 1231b may have an open shape at both ends of the guide member 1231b in the extending direction. Here, among both ends of the guide member 1231b in the extending direction, one end of the opening facing the fixed pipe part 1100 may be provided so that a part of the coupling part 1234, which will be described later, is inserted. In addition, the opening of the other end is provided to enable the elevating or moving of the fixing member (1231a).

The elastic part 1231c connects the upper plate 31a mounted on the guide member 1231b, the lower plate 31b mounted on the fixing member 1231a, and the upper plate 31a and the lower plate 31b, and is deformed by an external force. This is possible and includes an elastic member 31c having an elastic force.

The upper plate 31a is installed to surround the outer circumferential surface of the guide member 1231b. More specifically, the upper plate 31a may have a hollow shape in which an empty space is provided in the center so that the guide member 1231b can pass therethrough. And, when the guide member 1231b is passed through the empty space in the center of the upper plate 31a, the upper plate is installed to surround the outer circumferential surface of the guide member 1231b. At this time, the upper plate 31a is fixedly installed to the guide member 1231b so as to be integral with the guide member 1231b.

The lower plate 31b is installed to surround the outer peripheral surface of the fixing member 1231a. The lower plate 31b may have the same or similar shape as the above-described upper plate 31a. That is, the lower plate 31b may have a hollow shape in which an empty space is provided in the center so that the fixing member 1231a can pass therethrough. And, when the fixing member 1231a is passed through the empty space in the center of the lower plate 31b, the lower plate 31b is installed to surround the outer circumferential surface of the fixing member 1231a. At this time, the lower plate 31b is fixedly installed to the fixing member 1231a so as to be integral with the fixing member 1231a.

The elastic member 31c has one end connected to the upper plate and the other end connected to the lower plate 31b, and can be stretched and contracted between the upper plate 31a and the lower plate 31b. That is, the elastic member 31c is contracted by the force applied from the lower plate 31b to the upper plate 31a, and when released by the force, it is extended by the elastic force or the restoring force. More specifically, when the fixing member 1231a is raised, the lower plate 31b and the upper plate 31a are raised closer to each other, and the elastic member 31c positioned therebetween is contracted in the direction of the upper plate 31a. And when the force that raises the fixing member 1231a is released in this state, the elastic member 31c is extended in the direction of the lower plate 31b.

The elastic member 31c may be, for example, a spring. Of course, the elastic member 31c is not limited thereto, and can be contracted by an external force, and various means having an elastic force that can return to an original state when released by an external force can be applied.

The manipulation member 1231d may be formed to extend outwardly from the fixing member 1231a so that the operator can grab it by hand. More specifically, the operation member 1231d extends in a direction crossing or perpendicular to the extending direction of the fixing member 1231a, one end is connected to the fixing member 1231a, and the other end protrudes to the outside of the rotation flange 1232 . It can be arranged so that At this time, the manipulation member 1231d is connected to the fixing member 1231a so as to be positioned below the lower plate 31b.

The fixed flange 1233 is mounted on the fixed pipe unit 1100 to fix one end of the fixed unit 1231 to the fixed pipe unit 1100 . More specifically, the fixing flange 1233 may be installed to surround the outer circumferential surface of the fixing pipe 1110 . The fixed flange 1233 may have a shape similar to the above-described rotating flange 1232 . That is, the fixing flange 1233 may have a hollow shape in which an empty space is provided in the center so that the fixing pipe 1110 can pass therethrough. And, when the fixing pipe 1110 is passed through the empty space in the center of the fixing flange 1233 , the fixing flange 1233 is installed to surround the outer circumferential surface of the fixing pipe 1110 . At this time, the fixing flange 1233 is preferably installed on the fixing pipe 1110 so as to be integral with the fixing pipe 1110 . For example, the fixing flange 1233 and the fixing pipe 1110 are coupled by using a separate coupling means, or coupled by a bonding method such as welding.

Also, a hole (hereinafter, a coupling hole 1233a) into which a portion of the coupling portion 1234 is inserted may be provided in the fixing flange 1233 . In addition, a screw thread capable of being engaged with the coupling portion 1234 may be provided on the inner circumferential surface of the coupling hole 1233a.

The coupling part 1234 is a means for fastening the guide member 1231b to the fixing flange 1233 more specifically than the fixing part 1231 . The coupling portion 1234 is a coupling member 1234a inserted to pass through an opening, which is one end of the coupling hole 1233a and the guide member 1231b provided in the fixing flange 1233 , and the coupling member from the upper side of the fixing flange 1233 . It may include a fastening member 1234b fastened to the 1234a.

The coupling member 1234a may be provided with a screw thread capable of being engaged with the screw thread provided in the coupling hole 1233a on its outer peripheral surface. In addition, the fastening member 1234b may have a hollow shape through which the coupling member 1234a can pass, and may have a screw thread provided on the inner circumferential surface so as to be engaged with the screw thread provided in the coupling member 1234a. Such a coupling member 1234a may be a bolt, and the coupling member 1234b may be a nut.

In the above description, it has been described that the fixing unit 1230 includes the fixing flange 1233 , and the guide member 1231b is connected to the fixing pipe unit 1100 through the fixing flange 1233 . However, the fixing unit 1230 may not be provided with the fixing flange 1233 , and one end of the guide member 1231b may be provided to be directly coupled to the fixing pipe unit 1100 .

Hereinafter, with reference to FIGS. 1 to 5, a method of spraying a spray using a spraying facility according to an embodiment of the present invention will be described.

First, the injection unit 1221 is moved toward the injection target position. That is, the injection unit 1221 is moved so that the injection port 1221a faces the injection target position. More specifically, by rotating the support body 1222 of the injector 1220 to move the injector 1221 in the horizontal direction, or by rotating the driving member 1223 to change the height of the injector 1221a, the injector 1221 ), or by rotating the moving pipe unit 1210 as shown in FIG. 2 , for example, the injection unit 1221 is moved in the horizontal direction.

At this time, if the distance between the current location of the injection hole 1221a and the injection target position is long, and it is difficult to adjust the injection hole 1221a toward the injection target position only by the rotational operation of the support body 1222 and the driving member 1223, first, By rotating the moving pipe portion 1210, the entire injection device 1200 is moved.

To this end, the fixing force for fixing the moving pipe unit 1210 to the fixed pipe unit 1100 is released so that the moving pipe unit 1210 is not rotated. That is, as shown in FIGS. 2 and 4 , the fixing unit 1230 connected to the fixed pipe unit 1100 and the moving pipe unit 1210 are separated.

Specifically for a method of releasing the fixing force of the moving pipe portion 1210, as shown in FIG. 4 , the other end of the fixing member 1231a is located above the through hole 1232a or the rotation flange 1232 . to raise the fixing member 1231a. As a more specific example, when the operation member 1231d is raised, the fixing member 1231a connected thereto is raised, and the other end of the fixing member 1231a is located outside the through hole 1232a, that is, above the through hole 1232a. rise until it becomes

When the other end of the fixing member 1231a is positioned above the through hole 1232a in this way, the fixing member 1231a and the rotation flange 1232 are separated. Accordingly, the fixing force of the first connection pipe 1211a to which the rotation flange 1232 is connected is fixed to the fixed pipe 1110 is released or lost. In other words, the fixing force in which the moving pipe unit 1210 is fixed to the fixed pipe unit 1100 is released or lost.

When the fixing force of the moving pipe unit 1210 is released in this way, the injector 1200 is moved. That is, a force is applied to at least one of the moving pipe unit 1210 and the injector 1220 so that the moving pipe unit 1210 can rotate around the fixed pipe unit 1100 . At this time, depending on the direction in which the force is applied, the moving pipe part 1210 rotates clockwise or counterclockwise around the fixed pipe part 1100 as shown in FIG. 2 , for example.

The rotation of the moving pipe unit 1210 will be described in more detail as follows. The rotation connecting member 1211d and the first connecting pipe 1211a coupled to the joint 1300 and the rotation connecting member 1211d are formed to extend in the arranging direction and coupled to the rotating connecting member 1211d so that the position in the horizontal direction does not change. It rotates and rotates on the spot.

And, the intermediate pipe 1211c extending to cross or perpendicular to the first connecting pipe 1211a is rotationally moved by the rotation of the first connecting pipe 1211a, and the intermediate pipe 1211c is horizontally positioned so that the position is changed. rotate That is, the intermediate pipe 1211c rotates around one end connected to the first connecting pipe 1211a so that the horizontal position of the other end connected to the second connecting pipe 1211b is changed. When the intermediate pipe 1211c rotates in this way, the second connection pipe 1211b connected thereto also moves. Accordingly, the horizontal position of the injection unit 1221 connected to the second connection pipe 1211b is changed. That is, as shown in FIG. 2 , the intermediate pipe 1211c, the second connection pipe 1211b and the injector 1220 of the moving pipe 1211 move so as to change the horizontal position. At this time, it is preferable to move the injection port 1221a of the injection unit 1221 so that the injection target position can be viewed or as close as possible to the injection target position.

And, when the moving pipe 1211 and the injector 1220 move in this way, the rotating flange 1232 mounted on the moving pipe 1211 also rotates together. That is, by the rotation of the first connection pipe 1211a, the rotation flange 1232 mounted thereon rotates together.

When the injection port 1221a of the injection unit 1221 is able to see the injection target position or becomes as close as possible to the maximum, the moving pipe unit 1210 does not rotate, as shown in FIGS. 1 and 5, the fixture 1230 ) to fix the moving pipe unit 1210 to the fixed pipe unit 1100 .

To this end, first, it is checked whether the fixing member 1231a faces the through hole 1232a provided in the rotation flange 1232 . For example, when the through-hole 1232a is not positioned to face the fixing member 1231a, the through-hole 1232a located closest to the fixing member 1231a among the plurality of through-holes 1232a is the fixing member 1231a. ) and the moving pipe 1211 is rotated and moved by a predetermined amount to face. That is, additional rotation moves.

Thereafter, when the through hole 1232a is positioned to face the lower side of the fixing member 1231a, the force applied to the fixing member 1231a is released. That is, the current fixing member 1231a is in a state in which a force is applied to the fixing member 1231a so that the other end thereof is located above the through hole 1232a, and this force is released. To give a more specific example, if the current operator is holding the operation member 1231d connected to the fixing member 1231a so that the other end of the fixing member 1231a is located above the through hole 1232a, When the operator releases the operation member 1231d, the force holding the fixing member 1231a is released.

When the force applied to the fixing member 1231a is released in this way, the force applied to the elastic part 1231c is released. Accordingly, the fixing member 1231a is lowered by the elastic force of the elastic part 1231c. At this time, since the fixing member 1231a faces the through hole, at least a portion of the fixing member 1231a is inserted into the through hole as shown in FIG. 5 . Accordingly, the fixing member 1231a is fastened to the rotation flange 1232 . In this case, the fixing member 1231a is connected to the guide member 1231b, and the guide member 1231b is coupled to the fixing pipe unit 1100 . Accordingly, the fixing member 1231a, the rotating flange 1232 and the moving pipe part 1210 are in a state fixed to the fixed pipe part 1100 whose positions do not change or do not move.

Next, by rotating at least one of the support body 1222 and the driving member 1223, an additional movement of more precisely adjusting the position of at least one of the horizontal direction and the vertical direction of the injection hole 1221a may be performed.

Of course, when the injection port 1221a is adjusted to face the injection target position only by rotational movement of the moving pipe unit 1210 , additional movement using the support body 1222 and the driving member 1223 may be omitted.

When the position of the injector 1220 is adjusted so that the injection port 1221a faces the injection target position, the injection material is injected as shown in FIG. 1 . To this end, the valve 1211e installed in the moving pipe 1211 is operated to communicate between the moving pipe 1211 and the injector 1220 . Accordingly, the spray of the moving pipe 1211 is discharged, that is, sprayed through the injection hole 1221a of the injection unit 1221 .

At this time, a repulsive force is generated by the injection pressure injected from the injection unit 1221 . However, the moving pipe unit 1210 is not rotated or moved by this repulsive force, or its moving distance is very small. This is because the fixing unit 1230 fixes the moving pipe unit 1210 to the fixed pipe unit 1100 so that the moving pipe unit 1210 does not rotate.

Therefore, according to the injection facility 1000 according to the embodiment of the present invention, when the injection material is injected from the injection unit 1221, the moving pipe unit 1210 or the injection device 1200 as a whole rotates due to the repulsive force. can be prevented or suppressed. Accordingly, it is possible to prevent an accident caused by the rotation of the moving pipe unit 1210 or the injection device 1200 while the injection material is injected from the injection unit 1221 .
