Description

Spray device and spray method {SPRAY APPARATUS AND SPRAY METHOD}

The present invention relates to an injection device and an injection method, and more particularly, to an injection device and an injection method capable of suppressing the effects of injection pressure.

Materials used in steelworks, such as coal, are transported by a conveyor belt to a manufacturing site for molten iron production or to a yard for stacking. In addition, while the material is being loaded and moved on the conveyor belt, a large amount of dust is generated by the material, and droppings of the material may be generated on the floor of the workplace where the conveyor belt is installed. Therefore, since the floor of the workplace where the conveyor belt is installed is contaminated by dust and falling coal, cleaning is required.

For cleaning, a spraying facility having a spray bottle for spraying water on the floor of the workplace is used. That is, the cleaning is performed by spraying water on the floor of the workshop through the spray gun. This injection facility is installed to connect a fixed pipe connected to a water tank for providing water, a spray case for spraying water, and a fixed pipe and a spray case, and a moving pipe that rotates around the fixed pipe so that the horizontal position is adjusted. includes

The spraying case is provided to be movable so as to spray water to the spraying target location. That is, the spray gun is provided so as to be rotatable about one end thereof so that its horizontal direction position is changed.

However, when the current location of the injection event is far from the target injection location, it is difficult to adjust the injection event toward the target injection location by only rotating the injection event. Accordingly, a movable pipe connecting the fixed pipe and the spray gun is provided so as to be able to rotate around the fixed pipe. That is, the movable pipe may be rotated around the fixed pipe in a state of being connected to the fixed pipe, and thus the horizontal direction positions of the movable pipe and the spray gun are changed.

On the other hand, when water is injected from the injection case, a repulsive force is generated due to the injection pressure, and the repulsive force acts in a direction opposite to the direction in which the injection product is injected. That is, the repelling force by the injection pressure is transmitted to the movable pipe, so that the movable pipe can rotate around the fixed pipe.

In addition, water is injected at a high pressure according to the injection target position and the purpose of injection. As the injection pressure increases, the repelling force increases. Therefore, when the jet is injected at high pressure, the moving pipe can be strongly rotated around the fixed pipe by the repulsive force generated at this time. In this way, when the moving pipe is moved by the spraying pressure while water is sprayed from the spraying case, a safety accident may occur that damages surrounding facilities or exposes workers to danger.

One end of the opening connected to the driving member 1223 is an inlet through which the jet is introduced, and the other end of the opening is a jet opening 1221a through which the jet is discharged or sprayed.

The support body 1222 supports the driving member 1223 and the spraying unit 1221 and supplies the spray water provided from the moving pipe 1210 to the driving member 1223 and the spraying unit 1221 . That is, the support body 1222 is installed to connect between the spraying part 1221 and the moving pipe part 1210 or between the driving member 1223 and the moving pipe part 1210. In addition, the inside of the support body 1222 may be in communication with the movable pipe 1210, the driving member 1223, and the spraying unit 1221, and a passage through which the sprayed water can move is provided. That is, there is provided a passage through which the jet can move inside the support body 1222, one end of which communicates with the moving pipe 1210, and the other end communicates with the inlet of the jetting unit 1221. At this time, the other end of the support body 1222 may be in direct communication with the inlet of the injection unit 1221 or communicated through the driving member 1223 .

The support body 1222 is connected to the movable pipe part 1210 so as to be rotatable. More specifically, the support body 1222 extends in the vertical direction and can be rotated by an external force around a center in a width direction or a diameter direction intersecting the direction of extension as an axis. In this support body 1222, for example, the injection unit 1221 and the driving member 1223 are connected, and the gripping member 1222a provided so that the operator can grip and handle it by hand, and the gripping member 1222a and the moving pipe A support member 1222b connecting between the parts 1210 may be included.

The holding member 1222a and the supporting member 1222b each have a passage through which the spray can pass. At this time, the passage in the support member 1222b communicates with each passage of the movable pipe part 1210 and the holding member 1222a. Also, the passage of the holding member 1222a communicates with the support member 1222b and the injector 1220. At this time, the gripping member 1222a may communicate directly with the injection unit 1221 or indirectly through the driving member 1223 .

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

In addition, the rolling bearing may include an inner ring connected to the other end of the moving pipe 1210, an outer ring connected to the support body 1222, and a ball positioned between the inner ring and the outer ring. According to such a rolling bearing, the outer ring rotates by the external force transmitted through the support body 1222, and the support body 1222 mounted on the outer ring rotates.

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

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 as an axis by an external force. That is, when force is applied to the injector 1220, the support body 1222 rotates, and thus the entire injector 1220 rotates. At this time, the injector 1220 may be rotated by applying force to the injector 1220 in a clockwise or counterclockwise direction.

In applying force to the injector 1220 so that the injector 1220 rotates in this way, the operator grabs at least one of the gripping member 1222a of the support body 1222 and a lever 1224 described later to apply force. there is. Of course, it is not limited thereto, and the injector 1220 may be rotated by applying force to at least one of the support body 1222 and the lever 1224 as a separate device.

The driving member 1223 connects between the support body 1222 and the injection unit 1221, and is fastened to the support body 1222 to be rotatably connected to the injection unit 1221. More specifically, the driving member 1223 is fastened to the upper part of the support body 1222 so as to be rotatable in the front where the nozzle 1221a is located and in the opposite direction to the back, which is opposite to the nozzle 1221a, based on the support body 1222. do. In this case, the driving member 1223 may be fastened to an 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 perpendicular to the extending direction of the injection unit 1221 may be fastened to the gripping member 1222a so as to be rotatable forward or backward in response to an external force.

When the driving member 1223 is rotated forward or backward by an external force, the injection unit 1221 connected thereto moves up and down or moves up and down. That is, by rotating about one end of the injection unit 1221 connected to the driving member 1223, the other end, that is, the injection port 1221a moves up and down so that the height of the nozzle 1221a changes. In this way, the inclination or angle of the spraying part 1221 may be adjusted by the operation of moving the spraying part 1221 up and down so that the height of the spraying hole 1221a changes. That is, the spray angle of the spray may be adjusted by adjusting the angle between the spray unit 1221 and the floor of the workplace where the spray is to be sprayed.

The lever 1224 may be provided so that an operator can grasp and handle the lever 1224 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 so as to be located on the opposite side of 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 .

Meanwhile, as described above, the lever 1224 has been described as being capable of being handled by an operator holding it by hand, but is not limited thereto, and a separate device may be provided to operate the lever 1224.

The moving pipe part 1210 supplies the spray water provided from the fixed pipe part 1100 to the injector 1220 . And the moving pipe part 1210 is provided to be movable by an external force. More specifically, the movable pipe part 1210 is rotated around the fixed pipe part 1100 so that its horizontal position is changed or movable so as to be changed.

Here, the horizontal direction may refer to a direction parallel to the floor surface of a workplace where the jet is to be sprayed or an extension direction of the floor surface.

The moving pipe part 1210 supplies the spray water provided from the fixed pipe part 1100 to the injector 1220, and is driven by a pipe capable of moving by rotation (hereinafter referred to as a moving pipe 1211) and an external force. A moving member 1212 installed on the moving pipe 1211 is included.

The moving pipe 1211 connects the fixed pipe part 1100 and the injector 1220, and supplies the spray water provided from the fixed pipe part 1100 to the injector 1220. That is, the moving pipe 1211 communicates with the passages of the fixed pipe part 1100 and the injector 1220 therein, and has a passage through which the jet can move. And, of both ends of the passage, one end connected to the fixed pipe 1100 and the other end connected to the injector 1220 are open. Accordingly, after the jet supplied from the fixed pipe 1100 is introduced through one end of the moving pipe 1211, it is discharged through the other end and supplied to the injector 1220.

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

In more detail, the configuration of the movable pipe 1211 is described in detail. The movable pipe 1211 includes a first connection pipe 1211a connected to the fixed pipe part 1100 and a second connection pipe 1211a connected to the injector 1220 so as to be rotatable. It may include a pipe 1211b, an intermediate pipe 1211c connecting the first connection pipe 1211a and the second connection pipe 1211b, and in which the moving member 1212 is installed. Here, the first connection pipe 1211a, the intermediate pipe 1211c, and the second connection pipe 1211b may be integrally provided.

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

The first connecting pipe 1211a extends in the direction of arrangement of the joint 1300 and the rotary connecting member 1211d, one end is connected to the rotary connecting member 1211d connected to the joint 1300, and the other end is in 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 In addition, it may be described that the movable pipe part 1210 rotates around the fixed pipe part 1100 , that is, the fixed connection member 1120 .

The rotation connecting member 1211d connects the joint 1300 and the first connection pipe 1211a, and can be rotated while connected to the joint 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 later when the joint 1300 is described.

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.

Further, the rotation connecting member 1211d is provided to have a passage communicating with each passage of the joint 1300 and the first connection pipe 1211a. Accordingly, the jet passing through the joint 1300 may be moved to the first connection pipe 1211a via the rotation connecting member 1211d.

One end of the second connection 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 jet supplied 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, extended vertically or orthogonally to the floor of the workplace.

The intermediate pipe 1211c is a pipe connecting the first connection pipe 1211a and the second connection pipe 1211b. That is, the intermediate pipe 1211c has one end in its extending direction connected to the first connection pipe 1211a and the other end connected to the second connection pipe 1211b. Accordingly, the jet supplied from the first connection pipe 1211a may be moved to the second connection pipe 1211b via the intermediate pipe 1211c. And, it is preferable that the intermediate pipe (1211c) extends in a direction crossing or perpendicular to the first connecting pipe (1211a) connected to at least the rotation connecting member (1211d). As a more specific example, the first connection pipe 1211a may have a shape extending vertically or orthogonally to the floor of the workshop, and the intermediate pipe 1211c may have a shape extending 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 the 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 used as long as it is a means capable of controlling communication between the moving pipe 1211 and the injector 1220.

The movable member 1212 is installed to support the intermediate pipe 1211c while being driven by an external force. The movable member 1212 may be a means for driving the movable pipe 1210 to move in a direction crossing or perpendicular 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. The wheel may be provided to rotate in a direction crossing the extending direction of the intermediate pipe 1211c or in a radial direction of the intermediate pipe 1211c.

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

The joint 1300 connects the fixed connection member 1120 and the rotation connection member 1211d. At this time, the fixed connecting member 1120 is connected to be fixed to the joint 1300, and the rotation connecting member 1211d is connected to be rotatably connected to the joint 1300.

This joint 1300 may use well-known means. For example, joint 1300 may include, for example, a rolling bearing. 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 connecting member 1211d, and the rotation connecting member 1211d mounted on the outer ring rotates. And along with the rotation of the rotation connecting member 1211d, the moving pipe 1211 connected thereto also rotates.

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 rotation by an external force while the rotation connecting member 1211d is connected.

Hereinafter, movement of the injection device 1200 will be described.

The other end of the spraying unit, that is, the direction in which the spraying hole 1221a is viewed should be changed according to the target position to spray the sprayed water (hereinafter referred to as the spraying target position). That is, the spray hole 1221a should face or face the spray target position, and for this purpose, the spray unit 1221 is moved to adjust its position.

For example, the support body 1222 is rotated to adjust the horizontal position of the injection unit 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 face the injection target position.

On the other hand, as the position of the injection hole at the present time and the spray target position are farther away, it may be difficult to match the spray target position only by rotation of the support body 1222 and the lifting and lowering motion of the spraying unit 1221 . This is because the support body 1222 only rotates (ie, rotates) about the center in the width direction or the radial 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 nozzle 1221a can be adjusted by rotation of the driving member 1223, and the horizontal position cannot be adjusted.

Accordingly, when the spray hole 1221a cannot be directed toward the spray target position only by the rotation of the support body 1222 and the lifting and lowering motion of the spraying unit 1221, the entire spraying device 1200 is moved. That is, the moving pipe part 1210 is rotated around the fixed pipe part 1100 to adjust the horizontal position of the moving pipe part 1210 and the injector 1220 as shown in FIG. 2 .

To this end, force is applied to the injection device 1200 so that the movable pipe part 1210 can be rotated around the fixed pipe part 1100. At this time, according to the direction in which the force is applied, the rotating connecting member 1211d connected to the joint 1300 rotates clockwise or counterclockwise, and the rotational force of the rotating connecting member 1211d is the entire moving pipe 1211 is forwarded 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 part 1100. In other words, the moving pipe 1211 rotates around one end connected to the joint 1300 .

At this time, the rotating connection member 1211d connected to the joint 1300 by extending in the direction of arrangement of the fixed connecting member 1120 and the joint 1300 rotates in place while being connected to the joint 1300. do rotational movements. Accordingly, the horizontal position of the rotation connecting member 1211d may be fixed. In addition, the first connection pipe 1211a extending in the direction of arrangement of the joint 1300 and the rotation connection member 1211d and connected to be fixed to the rotation connection member 1211d is connected to the rotation connection member 1211d. , which rotates on the spot and performs a rotational motion. Accordingly, the horizontal position of the first connection pipe 1211a may be fixed.

Also, the intermediate pipe 1211c extending in a direction crossing or orthogonal to the extension direction of the first connection pipe 1211a moves such that its horizontal position is changed by the rotation of the first connection pipe 1211a. In other words, the intermediate pipe 1211c rotates around the fixed pipe 1100 or the first connection pipe 1211a. Accordingly, the horizontal position of the intermediate pipe 1211c is changed, and as a result, the horizontal position of the second connection pipe 1211b connected to the intermediate pipe 1211c and the injector 1220 connected to the second connection pipe 1211b is changed. move as much as possible

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

On the other hand, when the jet is injected from the injector 1220, a repulsive force is generated by the jet pressure, and the repulsive force acts in a direction opposite to the direction in which the jet is injected (see FIG. 1). That is, a shock may be applied to the moving pipe part 1210 connected to the injector 1220 by a repulsive force caused by the injection pressure.

In addition, the jet is jetted at high pressure according to the jetting target position and jetting purpose, and the repelling force increases as the jetting pressure increases. Accordingly, when spraying water at high pressure, the entire spraying device 1200 can be strongly rotated around the fixed pipe part 1100 by the repulsive force generated at this time. That is, the movable pipe part 1210 can be rotated around the fixed pipe part 1100 by the repelling force caused by the injection pressure (refer to the dotted line arrow in FIG. 1 ). And because of this, the injector 1220 connected to the moving pipe part 1210 also rotates and moves together, and eventually the entire injector 1200 can move.

If the moving pipe part 1210 or the entire spraying device 1200 is moved by the spraying pressure immediately after starting the spraying or during spraying, equipment around the spraying device 1200 is damaged or the operator is in danger. Exposure safety accidents may occur. Therefore, in order to prevent the movement of the moving pipe part 1210 while the spray is being sprayed, the spraying operation can be performed while the operator is holding the injector 1200, but the operator is fixing the injector 1200. has limitations and requires a lot of strength.

Therefore, the present invention provides an injection device 1200 having a holder 1230 capable of preventing or inhibiting the movement of the injection device 1200 by injection pressure. More specifically, an injection device having a fixture 1230 capable of preventing or suppressing rotational movement of the moving pipe part 1210 by injection pressure is provided.

Hereinafter, with reference to FIGS. 3 to 5, a spraying 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 the 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 rotary flange, and FIG. 5 is a state in which it is inserted.

3 to 5, the fixture 1230 is mounted and fixed to the movable pipe 1211 so as to be rotatable together with the movable pipe 1211, and has a rotating flange having a hole (hereinafter referred to as a through hole 1232a). 1232 and a fixing part 1231 that is connected to the fixed pipe part 1100 and can be fastened and separated from the rotary flange 1232. In addition, the fixture 1230 may include a fixed flange 1233 fixed to the fixed pipe 1100 and a coupling part 1234 coupling the fixing part 1231 to the fixed flange 1233 .

The rotating flange 1232 is installed on the rotatably movable moving pipe 1211 and may be installed to surround an outer circumferential surface of the moving pipe 1211 . More specifically, the rotary flange 1232 may have a hollow shape with an empty space in the center so that the first connection pipe 1211a may pass therethrough. Then, when the first connecting pipe 1211a passes through the empty space in the center of the rotating flange 1232, the rotating flange 1232 is installed to surround the outer circumferential surface of the first connecting 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 joining method such as welding.

In addition, a through hole 1232a is provided in the rotation flange 1232 and is provided to penetrate the rotation flange 1232 in the extension direction of the fixing part 1231 . That is, the through hole 1232a is provided to pass through the rotary flange 1232 in a vertical direction or a thickness direction. A plurality of through-holes 1232a are provided, and the plurality of through-holes 1232a are arranged in a direction of rotation 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 rotation flange 1232 or the first connection pipe 1211a. Of course, the number of through holes 1232a is not limited to the above-mentioned example of 8, and may be less than or greater than 8.

In the above, it has been described that the rotation flange 1232 is installed in the first connection pipe 1211a of the moving pipe 1211. However, it 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 moved up and down so that a part can be inserted into or taken out of the through hole 1232a provided in the rotary flange 1232 to be fastened and separated from the rotary 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 fixed pipe part 1100, and a guide member having a guide passage capable of inserting and moving the fixing member 1231a therein ( 1231b), one end connected to the guide member 1231b and the other end connected to the fixing member 1231a, so that the fixing member 1231a can be moved up and down by an external force and has an elastic force (1231c) ).

Also, the fixing part 1231 may include an operating member 1231d extending outwardly from the fixing member 1231a so that the operator can grip it by hand.

The fixing member 1231a is fastened with the rotation flange 1232 to prevent rotation of the rotation flange 1232 or the first connection pipe 1211a, or prevents rotation of the rotation flange 1232 or the first connection pipe 1211a. It is a means that is separable from the rotation flange 1232 so that it is possible. The fixing member 1231a may have a shape extending toward the rotation flange 1232 so as to be fastened to and detached from the rotation flange 1232 . In other words, the fixing member 1231a may have a shape extending in a direction in which the fixed pipe 1100 and the moving pipe 1211 or the fixed pipe 1100 and the rotating flange 1232 are arranged. In other words, the fixing member 1231a may have a shape extending vertically.

The fixing member 1231a is provided to be able to go up and down by an external force, and at least a part thereof is provided to go up and down 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 located inside the guide member 1231b. In addition, according to the lifting and lowering operation of the fixing member 1231a, the other end is located on the upper side of the rotation flange 1232 or the through hole 1232a provided in the rotation flange 1232, or passes through the through hole 1232a to It may protrude into the through hole 12132a or to the lower side thereof.

In positioning the other end of the fixing member 1231a on the upper side of the rotation flange 1232 or the through hole 1232a provided in the rotation flange 1232, the other end of the fixing member 1231a is on the upper side of the rotation flange 1232. It is desirable to avoid contact with the surface. In other words, it is preferable that the other end of the fixing member 1231a is spaced upward from the upper surface of the rotary 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 ( 1210) cannot rotate. 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 in the first connection pipe 1211a is fixed without rotation. Conversely, when the other end of the fixing member 1231a is positioned above the through hole 1232a or the rotation flange 1232, the movable pipe part 1210 may rotate around the fixed pipe part 1100. That is, the rotating connecting member 1211d and the first connecting pipe 1211a may be rotated by an external force. This is because the fixing member 1231a is separated from the rotational flange 1232 installed in the first connection pipe 1211a, and there is no force to block the rotational force of the rotational flange 1232.

It is effective that the other end of the fixing member 1231a penetrating the through hole 1232a of the rotary flange 1232 is provided in a shape in which the width or diameter decreases toward the lower end. In this case, the other end of the fixing member 1231a may more easily 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 a downward direction as shown 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 than when the fixing member 1231a has a sharp edge.

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

However, the fixing unit 1230 may not include the rotating flange 1232 and the fixing member 1231a may be directly connected to the movable pipe 1210 . For example, the other end of the fixing member 1231a may be provided with a means capable of fastening and separating the movable pipe part 1210, for example, a clamp or tongs.

The guide member 1231b is located on the upper side of the fixing member 1231a and one end is fixedly connected to the fixed pipe part 1100. The guide member 1231b may have a shape extending in the extension direction of the fixing member 1231a, and an empty space extending in the extension direction of the guide member 1231b, that is, a guide passage is provided therein. In addition, both ends of the guide member 1231b in the extending direction may be open. Here, among both ends of the guide member 1231b in the extension direction, one end of the opening toward the fixed pipe part 1100 may be provided to insert a part of the coupling part 1234 described later. In addition, the opening at 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 between 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 elasticity.

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 having an empty space in the center so that the guide member 1231b may pass therethrough. Then, when the guide member 1231b passes through the empty space in the center of the top plate 31a, the top 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 circumferential surface of the fixing member 1231a. The lower plate 31b may have the same or similar shape as the upper plate 31a described above. 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. Then, when the fixing member 1231a passes 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 integrated 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 extended 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 the force is released, the elastic member 31c is extended by the elastic force or 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 located between them is contracted in the direction of the upper plate 31a. In this state, when the lifting force of the fixing member 1231a is released, the elastic member 31c extends toward 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 can be applied with various means having an elastic force capable of returning to its original state when the external force is released.

The operating member 1231d may extend outwardly from the fixing member 1231a so that the operator can grip it by hand. More specifically, the operating member (1231d) extends in a direction crossing or orthogonal to the extending direction of the fixing member (1231a), one end is connected to the fixing member (1231a), and the other end protrudes outward from the rotating flange (1232). can be arranged so that At this time, the operating 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 part 1100 and fixes one end of the fixed part 1231 to the fixed pipe part 1100 . More specifically, the fixed flange 1233 may be installed to surround the outer circumferential surface of the fixed pipe 1110. The fixed flange 1233 may have a shape similar to that of the rotation flange 1232 described above. That is, the fixed flange 1233 may have a hollow shape in which an empty space is provided in the center so that the fixed pipe 1110 can pass therethrough. Then, when the fixed pipe 1110 passes through the empty space in the center of the fixed flange 1233, the fixed flange 1233 is installed to surround the outer circumferential surface of the fixed pipe 1110. At this time, the fixed flange 1233 is preferably installed on the fixed pipe 1110 so as to be integrated with the fixed pipe 1110. For example, the fixed flange 1233 and the fixed pipe 1110 are coupled using a separate coupling means, or coupled by a joining method such as welding.

In addition, a hole into which a part of the coupling portion 1234 is inserted (hereinafter, coupling hole 1233a) may be provided in the fixing flange 1233 . Further, a screw thread that can be 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 part 1234 is a coupling member 1234a inserted through an opening that is one end of the coupling hole 1233a provided in the fixed flange 1233 and the guide member 1231b, and a coupling member from the upper side of the fixed flange 1233. (1234a) and fastening member (1234b) may be included.

Coupling member (1234a) may be provided with a screw thread that can engage with the screw thread provided in the coupling hole (1233a) on its outer circumferential surface. Further, the fastening member 1234b may have a hollow shape through which the coupling member 1234a may penetrate, and may have a screw thread formed on an inner circumferential surface so as to be engaged with the screw thread provided in the coupling member 1234a. The coupling member 1234a may be a bolt, and the fastening member 1234b may be a nut.

In the above, it has been described that the fixture 1230 includes the fixing flange 1233 and the guide member 1231b is connected to the fixing pipe 1100 through the fixing flange 1233. However, the fixer 1230 may be provided so that one end of the guide member 1231b is directly coupled to the fixing pipe 1100 without having the fixing flange 1233 .

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

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

To this end, the fixing force fixing the movable pipe part 1210 to the fixed pipe part 1100 is released so that the movable pipe part 1210 does not rotate. That is, as shown in FIGS. 2 and 4 , the fixture 1230 connected to the fixed pipe part 1100 and the moving pipe part 1210 are separated.

When explaining in detail how to release the fixing force of the movable pipe part 1210, as shown in FIG. 4, the other end of the fixing member 1231a is positioned above the through hole 1232a or the rotary flange 1232. The fixing member 1231a is raised so as to do so. As a more specific example, when the operating member 1231d is raised, the fixing member 1231a connected thereto rises, 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

When the other end of the fixing member 1231a is positioned above the through hole 1232a, the fixing member 1231a and the rotary flange 1232 are separated. Accordingly, the fixing force of the first connecting pipe 1211a to which the rotary flange 1232 is connected to the fixed pipe 1110 is released or lost. In other words, the fixing force by which the movable pipe part 1210 is fixed to the fixed pipe part 1100 is released or lost.

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

The rotation of the movable pipe part 1210 will be described in more detail below. The rotational connection member 1211d and the joint 1300 and the rotational connection member 1211d are extended in the direction of arrangement so that the first connection pipe 1211a coupled to the rotational connection member 1211d does not change its position in the horizontal direction. It rotates and rotates on the spot.

In addition, the intermediate pipe 1211c extending to intersect or orthogonal to the first connection pipe 1211a is rotated and moved by the rotation of the first connection pipe 1211a, and the intermediate pipe 1211c changes its position in the horizontal direction. rotate That is, the intermediate pipe 1211c rotates around one end connected to the first connection pipe 1211a so that the horizontal position of the other end connected to the second connection pipe 1211b changes. When the intermediate pipe 1211c rotates and moves 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 are moved so that their horizontal positions are changed. At this time, it is preferable to move the injection port 1221a of the injection unit 1221 so as to be able to look at the injection target position or to be as close as possible.

Also, 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. That is, the rotation flange 1232 mounted on the rotation of the first connecting pipe 1211a rotates together.

When the injection hole 1221a of the injection unit 1221 can face the injection target position or comes as close as possible, the fixing device 1230 as shown in FIGS. 1 and 5 prevents the moving pipe 1210 from rotating. ) to fix the movable pipe part 1210 to the fixed pipe part 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 positioned closest to the fixing member 1231a among the plurality of through holes 1232a is the fixing member 1231a. ) Rotate and move the moving pipe 1211 by a predetermined amount so as to face. That is, an additional rotational movement is performed.

Then, when the through hole 1232a is positioned facing 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 where force is being applied to the fixing member 1231a such that the other end is positioned above the through hole 1232a, but this force is released. As a more specific example, if the operator is currently holding the operating member 1231d connected to the fixing member 1231a so that the other end of the fixing member 1231a is positioned above the through hole 1232a, When the operator releases the control member 1231d, the force holding the fixing member 1231a is released.

When the force applied to the fixing member 1231a is released, the force applied to the elastic part 1231c is released. Accordingly, the fixing member 1231a descends due to the elastic force of the elastic part 1231c. At this time, since the fixing member 1231a faces the through hole, at least a part of the fixing member 1231a is inserted into the through hole as shown in FIG. 5 . Thus, the fixing member 1231a is fastened to the rotary flange 1232. At this time, the fixing member 1231a is connected to the guide member 1231b, and the guide member 1231b is coupled to the fixed pipe part 1100. Accordingly, the fixing member 1231a, the rotating flange 1232, and the movable pipe part 1210 are fixed to the fixed pipe part 1100, the position of which does not change or does not move.

Next, by rotating at least one of the support body 1222 and the driving member 1223, additional movement for 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 hole 1221a is adjusted toward the injection target position only by the rotational movement of the moving pipe part 1210, additional movement using the support body 1222 and the driving member 1223 can be omitted.

When the position of the injector 1220 is adjusted so that the injection hole 1221a faces the injection target position, the injection 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 sprayed water of the moving pipe 1211 is discharged through the spraying hole 1221a of the spraying unit 1221, that is, sprayed.

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

Therefore, according to the spraying equipment 1000 according to an embodiment of the present invention, when the spraying water is sprayed from the spraying unit 1221, the entire moving pipe part 1210 or the spraying device 1200 rotates due to the repelling force. can be prevented or suppressed. Accordingly, an accident caused by rotation of the moving pipe part 1210 or the entire spraying device 1200 while spraying water from the spraying unit 1221 can be prevented.
