Description

Technical Field

[0001] This invention relates to the field of auxiliary tools for spraying construction, and in particular to a color mark spraying device and construction method for grounded flat steel. Background Technology

[0002] In construction projects, electrical shafts (both high and low voltage), distribution rooms, and transformer substations are densely populated areas for laying grounding trunk lines. The primary function of grounding is to conduct hazardous currents, static charges, and lightning currents generated during electrical faults into the earth, preventing electric shocks, damage to equipment and lines, fires, static electricity damage, and ensuring the normal operation of the power system. It is also a safety measure to ensure the normal operation of electrical equipment and personal safety. The grounding trunk line is connected to the grounding device, diverting leakage currents, static charges, and lightning currents that may be generated on electrical equipment and other production equipment into the ground, thereby preventing electric shocks and potential fires, explosions, and other accidents. According to Article 23.2.6 of GB50303-2015 "Code for Acceptance of Construction Quality of Building Electrical Engineering," the entire length or section of the grounding trunk line and the surface near each connection point should be marked with alternating yellow and green stripes of equal width, ranging from 15mm to 100mm.

[0003] The traditional spray painting method involves measuring the required length of the grounding main line beforehand, measuring the width of the yellow-green stripes on the flat iron with a ruler, drawing the stripe boundaries with a marker, and then spraying yellow-green striped paint within the stripe boundaries. The flat iron is then installed after the paint dries. This traditional method has the following drawbacks: 1. The yellow-green stripes on the flat iron are measured manually, which introduces significant errors, resulting in inconsistent and non-standard spacing and slant of the stripes, leading to a poor appearance. 2. The manual measurement and drawing of the stripe spacing is repetitive, time-consuming, inefficient, and wasteful of labor and materials.

[0004] In existing grounding flat steel spraying devices, such as the utility model patent with application number 202022480759.8, a device for spraying grounding wires is disclosed. The main problem that this device solves is that the irritating odor of the paint will damage the respiratory tract of workers, and there is also a risk of corrosion if the paint is accidentally splashed onto the workers' skin. Furthermore, it can only achieve one color spraying for grounding wires and cannot achieve 45° stripe spraying. For example, utility model patent application number 202222149987.6 discloses a grounding flat steel diagonal pattern paint brush. Although this patent can apply diagonal pattern paint to grounding flat steel, it still has the following problems: 1. It can only paint one grounding wire at a time, resulting in low work efficiency; 2. The flat steel slot is of a fixed size, but the thickness of different models of grounding flat steel is inconsistent. When a grounding flat steel that does not match the size of the slot is placed in the slot, there is a gap between the grounding flat steel and the front and rear diagonal grooves. If the amount of paint applied or sprayed is not well controlled, the paint can easily flow into the gap and form drip stripes in areas that do not need to be painted, resulting in irregular marking stripes and a poor appearance; if a grounding flat steel of the matching size is placed in the slot, there is no margin between the grounding flat steel and the front and rear diagonal grooves, and the grounding flat steel is prone to jamming when being put in and taken out; when the grounding flat steel is taken out after painting, the paint is not dry, and the paint can easily rub against the sides of the slot, scratching the marking stripes.

[0054] S6: Step on the lifting pedal (45) to raise the spraying mold (3) until the locking block (453) pops into the positioning step 435. Stop stepping when you hear the first sound of the locking block (453) hitting the pedal lifting bracket (43).

[0055] S7: Push the frame (2) forward and position the rear wheel of the frame (2)'s traveling wheel (21) above the Y-shaped positioning frame (73) of the next frame positioning mechanism (7);

[0056] S8: Follow the construction methods of steps S4-S7 above until all the stripes of the grounding flat steel (8) are coated, and then turn off the air compressor equipment connected to the spray gun (64).

[0057] Working principle of the invention:

[0058] When the operator steps on the lifting pedal (45), the lifting pedal (45) moves downward. The lifting pedal (45) drives the spraying mold (3) to rise through the force transmission rope (44). The locking block (453) descends synchronously with the lifting pedal (45). During the descent, the locking block (453) is gradually compressed by the slope of the lowering groove (431). After the locking block (453) descends to the bottom of the lowering groove (431), it automatically springs into the positioning step (435). When the operator stops stepping on the lifting pedal (45), the locking block (453) is limited on the positioning step (435). Stepping on the lifting pedal (45) is limited along with the locking block (453), and the spraying mold (3) is pulled through the force transmission rope (44), so that the spraying mold (3) is lifted and then limited along with the lifting pedal (45).

[0059] When the operator steps on the lifting pedal (45) again, the lifting pedal (45) moves downward. The locking block (453) descends and disengages from the positioning step (435), then automatically springs into the extension area of ​​the riser groove (432) at the bottom of the positioning step (435). After the locking block (453) springs into the riser groove (432), the limit is released, and the operator stops stepping on the lifting pedal (45). The spraying mold (3) automatically rotates and descends due to its own weight, and pulls the lifting pedal (45) through the force transmission rope (44). As it rises, the locking block (453) follows the lifting pedal (45) and gradually slides through the transition arc surface (434) to the middle of the lifting groove (432). During the rising process, the locking block (453) is gradually compressed by the slope of the lifting groove (432). After the locking block (453) rises to the top of the lifting groove (432), it automatically bounces into the lowering groove (431) at the top of the lifting groove (432). At this time, the spraying mold (3) descends to the position, and the top of the locking block (453) is limited by the top of the lowering groove (431).

[0060] When the construction worker turns the handle (56), the second gear (55) rotates accordingly. The second gear (55) drives the first gear (54) and the cylindrical cam drum (53) to rotate. During the rotation of the cylindrical cam drum (53), the cam groove (531) rotates accordingly. The contact position between the cam groove (531) and the follower column (521) changes. The follower column (521) moves with the rotation of the cam groove (531). The movement of the follower column (521) drives the nozzle slider (52) to slide on the nozzle slide rail (51). During the process of the nozzle slider (52), the nozzle (6) moves accordingly, realizing the rotational feed control of the nozzle (6) spraying.

[0061] When the frame positioning mechanism (7) positions the frame (2), the rear wheel of the traveling wheel (21) moves to the position of the frame positioning mechanism (7), the traveling wheel (21) presses down the Y-shaped positioning frame (73), the positioning spring (72) is compressed, and when the traveling wheel (21) enters directly above the Y-shaped positioning frame (73), the positioning spring (72) extends upward to reset, the Y-shaped positioning frame (73) is lifted, and the V-shaped groove at the top of the Y-shaped positioning frame (73) abuts against the bottom sides of the traveling wheel (21), thereby realizing the positioning of the moving spraying position of the frame (2).

[0062] The advantages of this invention compared to the prior art are:

[0063] 1. The device of the present invention has a reasonable structural design, is easy to manufacture with readily available materials, and is quick and easy to assemble, disassemble, and transport; it can be used repeatedly and has a high reusability rate.

[0064] 2. By using the spraying mold (3) to pre-determine the spraying position on the grounding flat steel (8), the spraying position of the grounding flat steel (8) can be made more accurate, thereby ensuring the visual quality requirements of the pre-painted double-color mark of the grounding busbar.

[0065] 3. This device can perform spraying work on more than 10 grounding flat steels (8) at a time, which greatly improves the efficiency of double-color marking spraying work on grounding flat steels (8).

[0066] 4. The present invention has wheels (12) installed on the vehicle body (1) for movement, which makes it easy and effortless to push the trolley when transferring the spraying work surface, thus reducing labor intensity.

[0067] 5. Construction workers can raise and lower the spraying mold (3) by stepping on the lifting pedal (45). It is fast and efficient, and does not require construction workers to bend over to operate, saving time and effort.

[0068] 6. Multiple stripes can be sprayed through the nozzle (6) to improve work efficiency. The nozzle (6) can be moved by rotating the handle (56) of the nozzle tilting mechanism (5), which makes it easier for construction personnel to control the spraying speed of the nozzle (6) and can spray ground flat steel (8) with a large span at a uniform speed.

[0069] 7. Position the frame (2) by positioning the frame (7). The frame (2) can be positioned by pushing it to the position of the frame positioning mechanism (7). The positioning speed is fast and no manual operation is required by the construction personnel, resulting in high work efficiency. Attached Figure Description

[0092] To enable those skilled in the art to better understand the technical solution of the present invention, the specific embodiments are described in detail below with reference to the accompanying drawings.

[0093] like Figure 1-14As shown, a color mark spraying device for grounded flat steel includes two parallel frame guide rails 1 set on the ground. The frame 2 is rolled on the two frame guide rails 1 by four traveling wheels 21 on both sides. A spraying mold 3 is set below the frame 2. The spraying mold 3 is vertically slidably set on the vertical slide rails 22 on both sides of the frame 2 by several lifting sliders 31. A spraying frame lifting mechanism 4 is set on the transverse support 23 in the middle of the frame 2. A spray pipe oblique movement mechanism 5 is set on the oblique support 24 in the middle of the frame 2. A spray pipe 6 is slidably set on the spray pipe oblique movement mechanism 5. Several frame positioning mechanisms 7 are arranged on the inner side of one frame guide rail 1. The spacing of the frame positioning mechanisms 7 is adapted to the distance of each movement of the spraying mold 3.

[0094] In some embodiments, such as Figure 4 As shown, a mold tie rod 32 is provided in the middle of the spraying mold 3; the spray pipe 6 is located between the mold tie rod 32 and the spraying groove 33, and the height distance between the mold tie rod 32 and the spraying groove 33 is not less than 80mm, so that the spraying mold 3 will not collide with the spray pipe 6 when it is raised and lowered.

[0095] In some embodiments, such as Figure 4 As shown, the spraying mold 3 is a parallelogram frame structure. Several spraying grooves 33 are set at an angle of 45° inside the frame structure of the spraying mold 3. The spacing of the spraying grooves 33 is adapted to the color mark spacing of the grounding flat steel 8.

[0096] The inclined bracket 24 forms a 45° angle with the frame guide rail 1, and the inclined bracket 24 is parallel to the spraying tank 33.

[0097] In some embodiments, such as Figure 4 As shown, the spray frame lifting mechanism 4 includes a first pulley 41 located in the middle of the horizontal support 23 and a second pulley 42 located at the front end of the horizontal support 23. A pedal lifting bracket 43 is provided on the frame 2 directly below the front end of the horizontal support 23, and the second pulley 42 is located directly above the pedal lifting bracket 43. A lifting pedal 45 is vertically slidably provided on the pedal lifting bracket 43. The first end of the force transmission rope 44 is connected to the mold pull rod 32 in the middle of the spray mold 2, and the second end passes through the first pulley 41 and the second pulley 42 in sequence before connecting to the lifting pedal 45.

[0098] In some embodiments, such as Figure 5-7 As shown, the front end face of the pedal lifting bracket 43 is vertically provided with a descending groove 431 and a rising groove 432, and a limiting partition 433 is provided between the descending groove 431 and the rising groove 432; the descending groove 431 is a guide groove for the locking block 453 to descend, and the rising groove 432 is a guide groove for the locking block 453 to rise. The limiting partition 433 is used to separate the middle area of ​​the descending groove 431 and the rising groove 432, and to limit the position of the locking block 453 when it rises and falls, so as to prevent the locking block 453 from deviating when it rises and falls.

[0099] In some embodiments, such as Figure 5-7 As shown, the top of the descending groove 431 extends to the top of the ascending groove 432, and the bottom of the ascending groove 432 extends to the bottom of the descending groove 431. A transition arc surface 434 is provided at the top extension of the descending groove 431 and the bottom extension of the ascending groove 432. A positioning step 435 is provided at the junction of the bottom of the descending groove 431 and the bottom extension of the ascending groove 432.

[0100] In some embodiments, such as Figure 5-7 As shown, the depth of the descending groove 431 decreases from deep to shallow from top to bottom, while the depth of the ascending groove 432 increases from shallow to deep from top to bottom. The depth of the top of the descending groove 431 is greater than the depth of the top of the ascending groove 432, and the depth of the bottom of the ascending groove 432 is greater than the depth of the bottom of the descending groove 431. The top of the descending groove 431 extends to the top of the ascending groove 432, and the bottom of the ascending groove 432 extends to the bottom of the descending groove 431. A transition arc surface 434 is provided at the extension of the top of the descending groove 431 and the extension of the bottom of the ascending groove 432. A positioning step 435 is provided at the junction of the bottom of the descending groove 431 and the bottom of the ascending groove 432.

[0101] When the operator steps on the lifting pedal 45, the lifting pedal 45 moves downward. The lifting pedal 45 drives the spraying mold 3 to rise through the force transmission rope 44. The locking block 453 descends synchronously with the lifting pedal 45. During the descent, the locking block 453 is gradually compressed by the slope of the lowering groove 431. After the locking block 453 descends to the bottom of the lowering groove 431, it automatically springs into the positioning step 435. When the operator stops stepping on the lifting pedal 45, the locking block 453 is limited on the positioning step 435. Stepping on the lifting pedal 45 is limited along with the locking block 453, and the force transmission rope 44 pulls the spraying mold 3, causing the spraying mold 3 to be lifted and then limited along with the lifting pedal 45.

[0102] When the operator steps on the lifting pedal 45 again, the lifting pedal 45 moves downward. After the locking block 453 descends and disengages from the positioning step 435, it automatically springs into the extension area of ​​the rising groove 432 at the bottom of the positioning step 435. After the locking block 453 springs into the rising groove 432, the limit is released. The operator stops stepping on the lifting pedal 45. The spraying mold 3 automatically rotates and descends due to its own weight, and pulls the lifting pedal 45 upward through the force transmission rope 44. The locking block 453 follows the lifting pedal 45 upward and gradually slides to the middle of the rising groove 432 through the transition arc surface 434. During the upward process, the locking block 453 is gradually compressed by the slope of the rising groove 432. After the locking block 453 rises to the top of the rising groove 432, it automatically springs into the descending groove 431 at the top of the rising groove 432. At this time, the spraying mold 3 descends to the position, and the top of the locking block 453 is limited by the top of the descending groove 431.

[0103] In some embodiments, such as Figure 5-8As shown, a mechanism groove 451 is provided at the front end of the lifting pedal 45. A locking spring 452 and a locking block 453 are provided in the mechanism groove 451. The end of the locking spring 452 is fixedly set on the bottom surface of the mechanism groove 451, and the end of the locking block 453 is fixedly set on the front end of the locking spring 452. The front end of the locking block 453 extends into the lowering groove 431 or the raising groove 432. The height of the mechanism groove 451 is adapted to the thickness of the locking block 453. The locking block 453 is connected by the locking spring 452. The upper and lower sides of the mechanism groove 451 restrict the vertical displacement of the locking block 453, so that the locking block 453 has only two degrees of freedom: extension and retraction and left and right rotation. This prevents the locking block 453 from having too much freedom and affecting its locking effect.

[0104] In some embodiments, such as Figure 6 , 7 As shown, the front end of the locking block 453 extends into the lowering groove 431 or the raising groove 432, so that the locking block 453 can smoothly enter the lowering groove 431 or the raising groove 432 when it moves left or right.

[0105] In some embodiments, such as Figure 6 , 7 As shown, pedal slide rails 454 are vertically arranged on both sides of the front end face of the pedal lifting bracket 43, and pedal sliders 455 are fixedly arranged on both sides of the lifting pedal 45. The two pedal sliders 455 are slidably arranged on the two pedal slide rails 454 respectively. The pedal slide rails 454 and pedal sliders 455 are used to restrict the movement direction of the lifting pedal 45, so that the lifting pedal 45 can only move up and down.

[0106] In some embodiments, such as Figure 9 , 10 As shown, the nozzle oblique movement mechanism 5 includes a nozzle slide rail 51 located below the oblique support 24, a nozzle slider 52 slidably mounted on the nozzle slide rail 51, a nozzle mounting bracket 62 at the top of the nozzle 6 mounted on the nozzle slider 52, and a follower column 521 on one side of the nozzle slider 52; a cylindrical cam cylinder 53 is located on one side of the nozzle slide rail 51, and both ends of the cylindrical cam cylinder 53 are connected to the oblique support 24 through rotating seats. The cylindrical cam cylinder 53 is provided with a spiral cam groove 531, and the follower column 521 extends into the cam groove 531. The length of the cam groove 531 is adapted to the stroke of the nozzle slide rail 51; a first gear 54 is coaxially mounted on the rotating shaft at the front end of the cylindrical cam cylinder 53, and a second gear 55 is rotatably mounted directly above the first gear 54. The second gear 55 meshes with the first gear 54, and a handle 56 is coaxially connected to the axle of the second gear 55.

[0107] In some embodiments, the first gear 54 and the second gear 55 are helical gears with a helical angle of 22.5°. Through the transmission of the two helical gears, the 45° rotation angle of the cylindrical cam drum 53 is transformed to be perpendicular to the frame guide rail 1, which facilitates the operation of the rotating handle 56 by the construction personnel. The transmission ratio of the first gear 54 and the second gear 55 is not less than 1.5. Through the transmission of the first gear 54 and the second gear 55, the number of turns of the rotating handle 56 is reduced, thereby improving the working efficiency of rotating the cylindrical cam drum 53.

[0108] In some embodiments, when the operator turns the handle 56, the second gear 55 rotates accordingly. The second gear 55 drives the first gear 54 and the cylindrical cam drum 53 to rotate. During the rotation of the cylindrical cam drum 53, the cam groove 531 rotates accordingly, and the contact position between the cam groove 531 and the follower column 521 changes. The follower column 521 moves along with the rotation of the cam groove 531. The movement of the follower column 521 drives the nozzle slider 52 to slide on the nozzle slide rail 51. During the movement of the nozzle slider 52, the nozzle 6 moves accordingly, thereby realizing the rotational feed control of the nozzle 6 for spraying.

[0109] In some embodiments, such as Figure 9 , 10 As shown, the spray pipe 6 is equipped with several nozzles 61. The spray pipe 6 is parallel to the frame guide rail 1. The nozzles 61 are located above several spraying slots 33, so that multiple spraying slots 33 can be sprayed at the same time, thereby improving work efficiency.

[0110] In some embodiments, such as Figure 2 As shown, the nozzle 6 is connected to the spray gun 64 via the guide hose 63. The spray gun 64 is fixed on the frame 2 and is connected to the air compressor via the air pipe. The spray gun 64 has a structure with its own paint tank, as is common in the prior art.

[0111] In some embodiments, such as Figure 11 , 12 As shown, the frame positioning mechanism 7 includes a limiting sleeve 71 fixed at the bottom of the inner side of a frame guide rail 1, a positioning spring 72 is provided inside the limiting sleeve 71, and the bottom end of the positioning spring 72 is fixed to the bottom end of the limiting sleeve 71; the lower vertical rod of the Y-shaped positioning frame 73 is slidably arranged inside the limiting sleeve 71, and the bottom end of the Y-shaped positioning frame 73 is connected to the top end of the positioning spring 72.

[0112] The frame positioning mechanism 7 is used to position the frame 2. During the process of the rear wheel of the traveling wheel 21 moving to the position of the frame positioning mechanism 7, the traveling wheel 21 presses down the Y-shaped positioning frame 73, and the positioning spring 72 is compressed. When the traveling wheel 21 enters directly above the Y-shaped positioning frame 73, the positioning spring 72 extends upward to reset, and the Y-shaped positioning frame 73 is lifted up. The V-shaped groove at the top of the Y-shaped positioning frame 73 abuts against the bottom sides of the traveling wheel 21, thereby realizing the positioning of the moving spraying position of the frame 2.

[0113] In some embodiments, such as Figure 1 , 2 As shown in Figure 11, a handle 25 is provided at the rear of the frame 2 to facilitate the construction personnel to push the frame 2.

[0114] In some embodiments, such as Figure 1 , 14 As shown, an end positioning strip 11 is provided on the ground inside one end of each of the two frame guide rails 1. The end positioning strip 11 is set at a 45° angle to the frame guide rail 1 and is used to position the end of the grounding flat steel 8. Several positioning blocks 12 are arranged along the guide rail direction on the ground inside one of the frame guide rails 1. The positioning blocks 12 are used to position the grounding flat steel 8 parallel to the frame guide rail 1 to prevent angle errors when the grounding flat steel 8 is sprayed with stripes.

[0115] In some embodiments, the thickness of the end positioning strip 11 and the positioning block 12 does not exceed the thickness of the grounding flat steel 8, to prevent the end positioning strip 11 and the positioning block 12 from blocking the spraying mold 3 from falling, and to create a gap between the spraying mold 3 and the grounding flat steel 8, so that paint can be sprayed into or flow into the area of ​​another color stripe from the gap.

[0116] How this invention works:

[0117] When using this invention:

[0118] Step 1: The construction workers arrange several grounding flat steel bars 8 between the two frame guide rails 1. The front end of the grounding flat steel bar 8 contacts the end positioning strip 11 for positioning. One side of the first grounding flat steel bar 8 contacts the positioning block 12 for positioning. The other grounding flat steel bars 8 are arranged closely in sequence.

[0119] Step 2: Apply or spray paint of one color to the entire surface of the grounding flat steel 8. After the paint on the grounding flat steel 8 is completely dry, proceed to the next step.

[0120] Step 3: Add another color of paint to the paint tank on the spray gun 64, turn on the air compressor connected to the spray gun 64, push the frame 2 to one end of the end positioning strip 11, and position the rear wheel of the frame 2's traveling wheel 21 above the Y-shaped positioning frame 73 of the first frame positioning mechanism 7. As the rear wheel of the traveling wheel 21 moves to the position of the frame positioning mechanism 7, the traveling wheel 21 presses down the Y-shaped positioning frame 73, and the positioning spring 72 is compressed. When the traveling wheel 21 enters directly above the Y-shaped positioning frame 73, the positioning spring 72 extends upward to reset, and the Y-shaped positioning frame 73 is lifted up. The V-shaped groove at the top of the Y-shaped positioning frame 73 abuts against the bottom sides of the traveling wheel 21, thereby achieving the positioning of the moving spray position of the frame 2.

[0121] Step 4: Step on the lifting pedal 45. The lifting pedal 45 moves downward. After the locking block 453 descends and disengages from the positioning step 435, it automatically springs into the extension area of ​​the lifting groove 432 at the bottom of the positioning step 435. After the locking block 453 springs into the lifting groove 432, it is released from its limit. Stop stepping when it can no longer be stepped on. The operator stops stepping on the lifting pedal 45. The spraying mold 3 automatically rotates and descends due to its own weight, and pulls the lifting pedal 45 upward through the force transmission rope 44. The locking block 453 follows the lifting pedal 45 upward and gradually slides to the middle of the lifting groove 432 through the transition arc surface 434. During the upward process, the locking block 453 is gradually compressed by the slope of the lifting groove 432. After the locking block 453 rises to the top of the lifting groove 432, it automatically springs into the descending groove 431 at the top of the lifting groove 432. After the spraying mold 3 is in contact with the grounding flat steel 8, the spraying mold 3 descends to its position, and the top of the locking block 453 is limited by the top of the descending groove 431.

[0122] Step 5: While the operator turns the handle 56 with one hand, they hold the spray gun 64 switch with the other hand to open the spray gun 64 switch and begin the painting process. When the operator turns the handle 56, the second gear 55 rotates accordingly, driving the first gear 54 and the cylindrical cam drum 53 to rotate. During the rotation of the cylindrical cam drum 53, the cam groove 531 rotates accordingly, and the contact position between the cam groove 531 and the follower column 521 changes. The follower column 521 moves along with the rotation of the cam groove 531, and the movement of the follower column 521 causes the nozzle slider 52 to slide on the nozzle slide rail 51. During the movement of the nozzle slider 52, the nozzle 6 moves accordingly. The process continues until the paint is applied, at which point the operator releases the spray gun 64 switch and stops turning the handle 56.

[0123] Step 6: The construction worker steps on the lifting pedal 45, which moves downward. The lifting pedal 45 drives the spraying mold 3 to rise through the force transmission rope 44. The locking block 453 descends synchronously with the lifting pedal 45. During the descent, the locking block 453 is gradually compressed by the slope of the lowering groove 431. After the locking block 453 reaches the bottom of the lowering groove 431, it automatically springs into the positioning step 435. The construction worker stops stepping when he hears the first sound of the locking block 453 hitting the pedal lifting bracket 43. The locking block 453 is limited on the positioning step 435. Stepping on the lifting pedal 45 is limited along with the locking block 453, and the force transmission rope 44 pulls the spraying mold 3, causing the spraying mold 3 to be lifted and then limited along with the lifting pedal 45.

[0124] S7: Then the construction workers push the frame 2 forward and position the rear wheel of the frame 2's traveling wheel 21 above the Y-shaped positioning frame 73 of the next frame positioning mechanism 7;

[0125] S8: Follow the construction methods of steps S4-S7 above until all the stripes of the grounding flat steel 8 are painted. Turn off the air compressor switch connected to the spray gun 64. After the painted grounding flat steel 8 is completely dry, take out the painted grounding flat steel 8 and put in a new batch of grounding flat steel 8 for stripe painting.
