Description

Pipe cleaning device {PIPE CLEANING DEVICE}

The present invention relates to a pipe cleaning device, and more specifically, to a pipe cleaning device that can easily remove rust or foreign substances by hand when they occur at welded areas of pipes used in semiconductor processing lines, etc.

In general, piping such as water pipes, gas pipes, etc. mainly consists of metal pipes connected by welding.

In addition, rust may occur on the surface when the pipes age or when the welded area is oxidized. Since this rust causes corrosion of the pipe, rust generated on the outer surface of the pipe, especially the welded area, must be removed.

In particular, in the case of pipes used to supply nitrogen gas to semiconductor process lines, if rust occurs at welded areas of these pipes, serious process losses can occur, so thorough management of the pipes is necessary.

For example, in order to supply gas such as nitrogen provided from an external gas source to various facilities on the semiconductor processing line, the gas is supplied after passing through an intermediate gas supply facility. In this case, the gas supply facility has a very narrow space. Since there is a piping structure in which pipes of small diameter are connected within the space, and there are many welded areas between each pipe, post-processing of the pipes, such as rust removal, must be performed before delivery of the equipment.

Usually, the way to remove rust from pipes is for workers to manually remove rust and foreign substances from the pipe surface one by one using a metal wire brush, sandpaper, or scrubber.

However, in harsh conditions where the internal space is small and pipes are intricately intertwined, there is a disadvantage in that work efficiency and productivity are reduced, such as requiring a lot of manpower, effort, and time, and it is difficult to expect quality in the rust removal area. There is.

The main body 10 is formed in the form of a box-shaped block with a plate portion extending toward the front end, and a main body cover 22 is attached to the rear part to close the inner space of the box-shaped block.

The front part of the main body 10 is used as an area where the cleaning mechanism 18 is installed, and various gears forming the electric mechanism 14 are installed inside the box-shaped block.

In addition, a port 23 is installed at the upper end of the main body 10, and each gear of the electric gear 14 can be operated smoothly by lubricant or the like injected through the port 23.

The handle 11 is a part that the user holds with his hand during rust removal work, and is made in the form of a hollow cylindrical bar and is installed in a structure that is coupled to the rear end of the main body 10.

In addition, a switch 25, for example, a switch 25 that can be turned on and off in a sliding manner, is installed on the other side of the handle 11, and the switch 25 can be turned on and off during rust removal work. Through this, power can be supplied or cut off to the motor 12.

In addition, the pipe cleaning device includes a motor 12 and a power source 13 as means for providing power and power required for rust removal work.

The motor 12 and the power unit 13 are installed inside the handle 11 and are electrically connected to each other, so that the motor 12 can be driven when power is supplied from the power unit 13.

Here, the power unit 13 preferably uses a replaceable battery (not shown) built into the handle 11 for ease of handling.

As another example, the power supply unit 13 may be powered by an external power source, and in this case, a power cord (not shown), a USB port (not shown), etc. are used to introduce external power to the motor built into the handle 11. It may be provided on the rear end of the handle 11.

Therefore, when the user turns ON the switch 25, the power supplied from the power supply unit 13 is supplied to the motor 12, and eventually the power according to the driving of the motor 12 can be transmitted to the electric mechanism 14. do.

In addition, the pipe cleaning device includes an electric mechanism 14 as a means of transmitting the power of the motor 12 to the cleaning mechanism 18.

The electric mechanism 14 is installed inside the main body 10, that is, inside a box-shaped block, and consists of a combination of a plurality of gears that mesh with each other and serve to transmit the power of the motor 12 to the cleaning mechanism 18. .

As an example, when one cleaning mechanism 18 of the first cleaning mechanism 18a is applied, the electric mechanism 14 includes a first gear 14a mounted on the shaft of the motor 12, and the first gear 14a. It is composed of a combination of a second gear (14b) that rotates in mesh with the first gear (14a) and a third gear (14c) that rotates in mesh with the first gear (14b).

And, the drive side pulley 15 of the cleaning mechanism 18, for example, the first drive side pulley 15a, is mounted on the axis of the third gear 14c.

Accordingly, the power of the motor 12 is transmitted from the first gear 14a to the second gear 14b to the third gear 14c, allowing the first drive side pulley 15a to rotate.

As another example, when a pair of cleaning mechanisms 18 of the first cleaning mechanism 18a and the second cleaning mechanism 18b are applied, the electric mechanism 14 is mounted on the shaft of the motor 12. A first gear (14a), a second gear (14b) rotating in mesh with the first gear (14a), a third gear (14c) rotating in mesh with the first gear (14b), and the first gear (14a) It is composed of a combination of a fourth gear (14d) that rotates in mesh and a fifth gear (14e) that rotates in mesh with the fourth gear (14d).

In addition, the drive side pulley 15 of the cleaning mechanism 18, for example, the first drive side pulley 15a, is mounted on the axis of the third gear 14c, and on the axis of the fifth gear 14e. A driving side pulley 15 of the cleaning mechanism 18, for example, a second driving side pulley 15b, is mounted.

Accordingly, the power of the motor 12 is transmitted from the first gear 14a → the second gear 14b → the third gear 14c, allowing the first drive side pulley 15a to rotate, and at the same time It is transmitted from the first gear (14a) → the fourth gear (14d) → the fifth gear (14e), allowing the second drive side pulley (15b) to rotate.

That is, when the cleaning mechanism 18 is composed of a pair of the first cleaning mechanism 18a and the second cleaning mechanism 18b, the motor 12 moves the first driving side pulley 15a and the second cleaning mechanism 18b by power. The two drive side pulleys 15b can be rotated simultaneously.

Here, the gears of the electric mechanism 14 can be a single gear type made of one gear, a dual gear type made of two integrated gears, etc.

Additionally, the pipe cleaning device includes a cleaning mechanism 18 as a means for substantially removing rust from the pipe while directly contacting the pipe.

The cleaning mechanism 18 receives power from the electric mechanism 14 and operates to remove rust from the pipe. Basically, it consists of a driving pulley 15, a driven pulley 16, and a driving pulley. It consists of a belt (17) that is connected between (15) and the driven side pulley (16) and directly contacts the pipe while operating.

In a preferred embodiment, the cleaning mechanism 18 may be a single belt type using one belt, but in terms of increasing the efficiency of rust removal work, a dual belt type using a pair of belts may be used. It's good.

To this end, the cleaning mechanism 18 is mounted on the axis of the third gear 14c of the electric mechanism 14 and rotates freely on the front end of the plate portion of the main body 10 and the first drive side pulley 15a that rotates together. A first cleaning mechanism including a first driven side pulley (16a) mounted in a possible structure and a first belt (17a) connected and installed between the first driving side pulley (15a) and the first driven side pulley (16a). (18a), the second drive side pulley (15b) mounted on the axis of the fifth gear (14e) of the electric mechanism (14) and rotating together, and the clamp bar (19) installed on the plate portion of the main body (10). It includes a second driven pulley (16b) mounted in a freely rotatable structure at the front end and a second belt (17b) connected and installed between the second driving side pulley (15b) and the second driven pulley (16b). It consists of a second cleaning mechanism 18b.

At this time, the first cleaning mechanism 18a and the second cleaning mechanism 18b of the cleaning mechanism 18 are arranged side by side with each other at the bottom and top, and the first belt of the first cleaning mechanism 18a arranged in this way ( 17a) and the second belt 17b of the second cleaning mechanism 18b rotate while being in contact with the pipe side with the pipe in between.

Here, the belt 17 used in the cleaning mechanism 18 may be a scrubber belt, sandpaper belt, etc.

In particular, the first belt 17a of the first cleaning mechanism 18a and the second belt 17b of the second cleaning mechanism 18b are connected to a transmission mechanism in the electric gear 14, for example, the first gear 14a. ), the second gear (14b) and the fourth gear (14d) are engaged and rotated at the same time to operate in opposite directions to each other by an electric mechanism, and as a result, the two belts scrape the outer peripheral surface of the pipe to the same side, ultimately leading to the pipe Rust can be removed more effectively.

And, as a means for providing tension to the first belt 17a and the second belt 17b, a tensioner 26 is attached to the first belt 17a and the second belt 17b, respectively, and these tensioners (26) is installed with a bolt fastening structure in the long hole 27 formed in the plate portion of the main body 10, and the tensioner 26 installed in this way can press the belt while contacting each belt side.

Of course, the position of the tensioner 26 can be adjusted by loosening or retightening the bolt fastening structure, and the first belt 17a and the second belt 17b can be adjusted through appropriate position adjustment of the tensioner 26. The tension can be adjusted.

Additionally, the pipe cleaning device includes a clamp mechanism 21 as a means for fixing the pipe when removing pipe rust.

The clamp mechanism 21 serves to hold the pipe when rust is removed from the pipe, that is, to tightly fix the pipe cleaning device to the pipe side.

This clamp mechanism 21 is composed of a clamp bar 19 that functions to tightly clamp the pipe side and a spring 20 that functions to pull the clamp bar 19 toward the pipe side.

The clamp bar 19 is in the form of a bar with a hook-shaped tip, and is installed on the main body 10 through the rear end in a structure supported by a hinge pin 28.

The clamp bar 19 installed in this way can be rotated around the hinge pin 28, and thus the pipe can be fixed by pressing it through the hook shape at the tip using this rotational movement.

The spring 20 is a type of tension spring, and is installed in a structure to elastically support the clamp bar 19 while being fixed at both ends between the clamp bar 19 and the main body 10. Accordingly, the clamp bar 19 is a spring Due to the pulling force in (20), it always receives a force that tends to bend toward the pipe.

In particular, an arc-shaped pipe seating groove 28 is formed at the tip of the main body 10, and when the pipe is pressed by the clamp bar 19, the pipe is partially accommodated in the pipe seating groove 28. It can be fixed so that it does not move.

Here, the tip of the clamp bar 19 for holding the pipe and the pipe seating groove 28 are located a certain distance inward between the first belt 17a and the second belt 17b of the cleaning mechanism 18. can be located.

Therefore, when the pipe is brought into the pipe seating groove 28 with the tip of the clamp bar 19 bent outward and the clamp bar 19 is released, the clamp bar 19 is pulled by the spring force. The pipe is pressed, and eventually the pipe can be fixed between the clamp bar (19) and the pipe seating groove (28).

Figure 6 is a perspective view showing a belt guide device in a pipe cleaning device according to an embodiment of the present invention.

As shown in FIG. 6, a belt guide device is shown here as a means for stable driving of the belt.

The belt guide device includes a roller block 31 that can move forward and backward on the main body 10, a roller bracket 33 installed on the side of the roller block 31, and a roller bracket 33 that rotates on the roller bracket 33. Installed in a possible structure, each guide roller 29 rotates together while being in close contact with the belt 17, that is, the first belt 17a and the second belt 17b, respectively, and penetrates the roller block 31 to the main body ( 10), an adjustment knob 32 installed with a screw fastening structure, a bearing 34 interposed between the outer peripheral surface of the adjustment knob 32 and the inner peripheral surface of the small diameter hole of the roller block 31, and the roller block ( In addition to being partially inserted into the large diameter hole of 31), it is supported at both ends between the spring support jaw 35 formed at the boundary between the large diameter hole and the small diameter hole of the roller block 31 and the head of the adjustment knob 32. It consists of a knob spring (30) that always pushes the roller block (31) forward.

Accordingly, the entire guide roller 29, including the roller block 31, is constantly pushed forward by the force exerted by the knob spring 30, and eventually the guide roller 29 is moved to the first belt. By being in close contact with the (17a) and the second belt (17b), separation of the first belt (17a) and the second belt (17b) is prevented and the first belt (17a) and the second belt (17b) are stably maintained. It can be driven.

At this time, by adjusting the elasticity of the knob spring 30 by adjusting the degree of fastening of the adjustment knob 32, the degree of adhesion between the guide roller 29 and the first belt 17a and the second belt 17b can be appropriately adjusted. There will be.

Accordingly, the usage status of the pipe cleaning device configured as described above is as follows.

Figures 7 and 8 are perspective views showing a use state of a pipe cleaning device according to an embodiment of the present invention.

As shown in FIGS. 7 and 8, the user holds the pipe cleaning device by hand using the handle 11, and then folds the first belt 17a and the second belt 17b while flipping the clamp bar 19. ), when the clamp bar 19 is placed after inserting the pipe 100 between the pipes 100 and the first belt 17a while being fixed by the pipe seating groove 29 and the clamp bar 19. It is located between two belts (17b).

Subsequently, when the switch 25 is turned ON, the motor 12 is driven, and the power at this time is transmitted to the cleaning mechanism 18 through each gear 14a to 14e of the electric mechanism 14, and at the same time, As the first belt (17a) and the second belt (17b) operate, they cause friction with the surface of the pipe (100). Therefore, the rust on the pipe (100) is cleanly removed by the friction of the belt, making the pipe rust removal work very easy. It can be done quickly and easily, and because the pipe cleaning device is small in size and can be easily handled by hand, pipe rust removal can be done efficiently even in places where space is limited.

As such, the present invention provides a new type of pipe cleaning device that can quickly and easily remove rust, etc., occurring in pipes such as semiconductor processing lines, thereby preventing pipes from being corroded by rust, etc. In addition to improving the durability of piping, process losses can be minimized, and because it is light in weight, simple to operate, and easy to handle, workers can easily handle it and can perform rust removal work, especially in narrow work spaces, reducing labor costs and In addition to reducing work time, work efficiency can be improved, and the quality of cleaning work can be improved by completely removing rust from welded areas of pipes, etc., while at the same time, semiconductor processing lines can be efficiently maintained and managed. .
