Description

Technical Field

[0001] The invention relates to the technical field of paint spraying devices, in particular to a pressure vessel surface anti-corrosion paint spraying treatment device. Background Art

[0002] A pressure vessel is a closed container that can withstand pressure. It is widely used in industrial production and daily life. Pressure vessels are often exposed to various corrosive media. These corrosive substances will chemically react with the metal on the surface of the container, gradually corroding the metal and reducing its strength and carrying capacity. Therefore, a paint treatment device is often used to form a protective film to isolate the metal surface from the corrosive medium, effectively slowing down the corrosion rate.

[0003] When using a traditional paint spraying device, an operator usually holds a spray gun and sprays around the container. However, when the pressure vessel is high, the operator needs to climb a ladder or stand on tiptoe to operate, which can easily cause uneven paint spraying at a high position of the container, and is inconvenient to operate and has poor flexibility. After painting, the paint spray gun is usually placed directly on the ground or hung on the iron frame of the equipment, which leads to poor stability of the paint spray gun. When the equipment shakes, the paint spray gun is easy to fall from the equipment, causing damage and poor stability. When the paint tube of the paint spray gun needs to be put away after spraying, the paint tube is usually directly wound around the equipment. Therefore, when the equipment is moved, the paint tube is easily dropped and entangled, or directly damaged, and the flexibility is poor. Summary of the invention

Two mounting sleeves 701 are connected to the limiting structure 6. A first clamp 703 and a second clamp 704 are respectively slidably connected between the two second guide rods 702.

The two mounting sleeves 701 are located in an upper and lower layer relationship.Then, the paint spray gun 9 is installed. It only needs to be inserted from the center of the two installation sleeves 701 from top to bottom. In the process of inserting the paint spray gun 9, the bottom end of the paint spray gun 9 first contacts with the first clamp 703 and the second clamp 704. In the process of continuously pressing the paint spray gun 9 downward, the first clamp 703 and the second clamp 704 are driven to slide back to back along the second guide rod 702 until the paint spray gun 9 completely passes through the upper and lower installation sleeves 701. At this time, the first clamp 703 and the second clamp 704 clamp the paint spray gun 9 under the reset action of the third spring 705, thereby preliminarily fixing the paint spray gun 9. Then, the upper and lower limit posts 706 are twisted in turn. Since the limiting column 706 is threadedly connected with the mounting sleeve 701, the end of the limiting column 706 contacts the first clamp 703, and the limiting column 706 is continuously rotated until the back side of the second clamp 704 contacts the inner wall of the mounting sleeve 701. At this time, under the contact force of the limiting column 706, the first clamp 703 and the second clamp 704 are tightly contacted with the paint spray gun 9, and the paint spray gun 9 is further fixed with strong firmness. At the same time, the paint spray gun 9 is installed on the telescopic rod 603. When spraying paint on a pressure vessel with a large height, the telescopic rod 603 can be used to spray paint at a higher position, thereby improving the uniformity of spraying paint and simplifying the operation. ;

In a static state, the first driving rod 802 slides to the top of the guide bar 801 under the reset action of the fourth spring 803, and contacts the second guide rod 702. At the same time, the roller 807 at the other end of the first driving rod 802 is located at the bottom of the second slide groove 806. Then, during the painting process, the pull rope 810 is pulled. Since the other end of the pull rope 810 is connected to the docking rod 808, the docking rod 808 is driven to move in the direction of the guide ring 809, and the docking rod 808 drives the first driving rod 802 to the end of the guide bar 801. The guide plate 805 rotates a certain angle around the second guide rod 702 until the bottom surface of the first driving rod 802 hits the limiting column 706, and the pull rope 810 is continuously pulled. At this time, the first driving rod 802 continues to slide along the guide bar 801 and rotates a certain angle around the limiting column 706. The first driving rod 802 drives the second driving rod 804 at the end to hit the switch of the paint spray gun 9. At this time, the paint in the inner liner 207 can be sprayed out through the paint spray gun 9, which solves the problem of difficulty in painting when the pressure vessel is at a high height and improves the painting efficiency.

[0025] Specifically, Figure 1-Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the mounting structure 2 includes four mounting frames 201 and a first rotating shaft 202 rotatably connected to the mounting frames 201, the four mounting frames 201 are fixedly connected to the outer wall of the paint spray bucket body 1, the first rotating shaft 202 is fixedly connected to a connecting rod 203, the top of the paint spray bucket body 1 is in contact with a sealing cover 206, the edge of the sealing cover 206 is fixedly connected with four limiting frames 205, the top of the connecting rod 203 is threadedly connected to a limiting sleeve 204, the bottom surface of the limiting sleeve 204 is in contact with the limiting frame 205, and the interior of the paint spray bucket body 1 is clamped with an inner liner 207; when spraying the pressure vessel During the painting process, the paint spray bucket body 1 moves freely through the universal wheels at the bottom, pours the paint into the inner liner 207, and then the inner liner 207 is engaged with the inside of the paint spray bucket body 1, and then the sealing cover 206 is covered, so that the limiting frame 205 on the sealing cover 206 is aligned with the mounting frame 201 on the paint spray bucket body 1, and then the connecting rod 203 is rotated 180 degrees through the first rotating shaft 202, and then the limiting sleeve 204 is threadedly connected to the end of the connecting rod 203, so that the bottom surface of the limiting sleeve 204 and the limiting frame 205 are in conflict with each other, and then the other three are repeated The same operation, at this time, the fixing of the sealing cover 206 is completed, the operation is simple, and the firmness is strong.

The grooves on the mounting seat 501 are aligned with each other, and then the bottom end of the grip rod 504 is snapped into the center position of the mounting seat 501. In the process of inserting the grip rod 504, the bottom cover 505 at the bottom end of the grip rod 504 first contacts the limit block 502, causing the limit block 502 to slide toward the inside of the mounting seat 501 until the grip rod 504 is completely inserted into the mounting seat 501. At the same time, the limit block 502 slides outward along the inner wall of the mounting seat 501 under the reset action of the first spring 503, and is snapped into the limit groove 507 on the grip rod 504, so that the grip rod 504 is inserted into the mounting seat 501. 504 and the paint spray gun 9 are installed on the equipment to avoid the problem of the paint spray gun 9 falling and being damaged when the equipment is moved. When it is necessary to remove the grip 504 and the paint spray gun 9, just press the telescopic rod 603 downward, and the telescopic rod 603 drives the driving block 508 to slide downward and compress the second spring 509. At the same time, the protrusion at the edge of the driving block 508 slides downward along the first slide groove 506 and contacts the limit block 502, so that the limit block 502 is no longer engaged with the limit groove 507. At this time, the grip 504 can be pulled out from the mounting seat 501, which is easy to operate.

[0027] Specifically, Figure 4-Figure 6 , Figure 8 and Fig. 9As shown, the limiting structure 6 includes a second rotating shaft 601 and a resistance strip 602 rotatably connected to the second rotating shaft 601, the top of the gripping rod 504 is fixedly connected to the two second rotating shafts 601, the inside of the gripping rod 504 is slidably connected to a telescopic rod 603, the resistance strip 602 resists the telescopic rod 603, the end of the gripping rod 504 is threadedly connected to a limiting ring 604, the limiting ring 604 resists the resistance strip 602, the top of the telescopic rod 603 is fixedly connected to two mounting sleeves 701, and the outer wall of the telescopic rod 603 is fixedly connected to two guide rings 809; if a pressure vessel with a larger volume is to be sprayed with paint, first adjust the telescopic rod 603 to extend outward from the inside of the gripping rod 504 To achieve the desired distance, the limiting ring 604 only needs to be removed from the top of the gripping rod 504, and then the telescopic rod 603 is pulled outward. When the telescopic rod 603 is pulled out to a suitable length, the limiting ring 604 is rotated in the opposite direction. Since the limiting ring 604 is threadedly connected to the top of the gripping rod 504, the limiting ring 604 will downwardly contact the two contact bars 602 during the downward movement, so that the two contact bars 602 rotate around the second rotating shaft 601, and at the same time, the ends squeeze the telescopic rod 603. Therefore, under the action of the contact force of the two contact bars 602, the telescopic rod 603 cannot slide inside the gripping rod 504, so that the position of the telescopic rod 603 is effectively fixed, and the adjustment of the outward extension length of the telescopic rod 603 is completed, which has strong flexibility.

[0028] Specifically, Figure 3 and Figure 6As shown, the clamping structure 4 includes a connecting frame 401 and a first fixing clamp 402 fixedly connected to the connecting frame 401, the connecting frame 401 is fixedly connected to the outer wall of the paint spray bucket body 1, the first fixing clamp 402 is fixedly connected to the first guide rod 403, the first guide rod 403 is slidably connected to the second fixing clamp 405, a tension spring 404 is fixedly connected between the bottom surface of the second fixing clamp 405 and the first fixing clamp 402, the second fixing clamp 405 is slidably connected to the first fixing clamp 402, a pull bar 406 is fixedly connected to the second fixing clamp 405, a resistance rod 407 is threadedly connected to the connecting frame 401, and a knob 408 is fixedly connected to the top of the resistance rod 407, the electric mixer 3 is fixedly connected to the center position of the sealing cover 206, and the safety valve 11, the feeding port 12, The air release valve 13 and the discharge port 14, the bottom end of which is engaged with a suction pipe 15; when the painting operation is completed, the paint spraying pipe is rolled up, and then the pull bar 406 arranged on the side wall of the paint spraying bucket body 1 is pulled upward, and then the pull bar 406 drives the second fixing clamp 405 to slide upward along the first guide rod 403 until the second fixing clamp 405 is completely offset from the first fixing clamp 402, and then the spraying pipe rolled into a circular ring is hung between the first fixing clamp 402 and the second fixing clamp 405, and then the pull bar 406 is released, and the second fixing clamp 405 is driven to slide downward and clamp the spraying pipe under the resetting action of the tension spring 404. When it is not used for a long time, by rotating the knob 408 above the connecting frame 401, the resistance rod 407 at the bottom is driven to resist the second fixing clamp 405, so that the second fixing clamp 405 can be effectively limited to prevent the spraying pipe from falling off the equipment during movement, and the stability is strong.

[0029] When the present invention is used, during the process of spraying paint on the pressure container, the paint spray bucket body 1 moves freely through the universal wheels at the bottom, and the paint is poured into the inner liner 207, and then the inner liner 207 is clamped inside the paint spray bucket body 1, and then the sealing cover 206 is covered, so that the limiting frame 205 on the sealing cover 206 and the mounting frame 201 on the paint spray bucket body 1 are aligned with each other, and then the connecting rod 203 is rotated 180 degrees through the first rotating shaft 202, and then the limiting sleeve 204 is threadedly connected to the end of the connecting rod 203, so that the bottom surface of the limiting sleeve 204 and the limiting frame 205 are in conflict with each other, and then the same operation is repeated for the other three, and then the fixing of the sealing cover 206 is completed, and the operation is simple and the firmness is strong; Since the electric stirrer 3 is installed at the center of the sealing cover 206, it is convenient to stir the paint in the inner tank 207. The bottom of the pressure regulating valve 10 is wrapped with raw tape and installed on the sealing cover 206. Then the safety valve 11, the feeding port 12, the air release valve 13 and the discharge port 14 are installed on the sealing cover 206 in sequence. At the same time, the air inlet pipe of the electric stirrer 3 is connected to the pressure regulating valve 10, and then the air inlet pipe of the paint spray gun 9 is connected to the pressure regulating valve 10. Finally, the pressure regulating valve 10 is connected to the external air compressor through another air inlet pipe. Since the suction pipe 15 engaged at the bottom of the discharge port 14 extends to the inside of the inner tank 207, the paint pipe of the paint spray gun 9 is connected to the discharge port 14, so that the paint flows into the paint spray gun 9 through the discharge port 14, and the spraying operation is completed, which has strong flexibility. When spraying paint on a pressure vessel with a larger volume, the distance that the telescopic rod 603 extends outward from the inside of the grip 504 is adjusted first. The limiting ring 604 only needs to be removed from the top of the grip 504, and then the telescopic rod 603 is pulled outward. When the telescopic rod 603 is pulled out to a suitable length, the limiting ring 604 is rotated in the opposite direction. Since the limiting ring 604 is threadedly connected to the top of the grip 504, the limiting ring 604 contacts the two contact bars 602 downward during the downward movement, so that the two contact bars 602 rotate around the second rotation axis 601, and the ends squeeze the telescopic rod 603 at the same time. Therefore, under the action of the contact force of the two contact bars 602, the telescopic rod 603 cannot slide inside the grip 504, and the position of the telescopic rod 603 is effectively fixed, and the adjustment of the extension length of the telescopic rod 603 is completed, which has strong flexibility. Then, the paint spray gun 9 is installed. It only needs to be inserted from the center of the two installation sleeves 701 from top to bottom. In the process of inserting the paint spray gun 9, the bottom end of the paint spray gun 9 first contacts with the first clamp 703 and the second clamp 704. In the process of continuously pressing the paint spray gun 9 downward, the first clamp 703 and the second clamp 704 are driven to slide back to back along the second guide rod 702 until the paint spray gun 9 completely passes through the upper and lower installation sleeves 701. At this time, the first clamp 703 and the second clamp 704 clamp the paint spray gun 9 under the reset action of the third spring 705, thereby preliminarily fixing the paint spray gun 9. Then, the upper and lower limit posts 706 are twisted in turn. Since the limiting column 706 is threadedly connected with the mounting sleeve 701, the end of the limiting column 706 abuts against the first clamp 703, and the limiting column 706 is continuously rotated until the back side of the second clamp 704 abuts against the inner wall of the mounting sleeve 701. At this time, under the abutting force of the limiting column 706, the first clamp 703 and the second clamp 704 are tightly abutted against the paint spray gun 9, and the paint spray gun 9 is further fixed at this time, and the firmness is strong. At the same time, the paint spray gun 9 is installed on the telescopic rod 603. When spraying paint on a pressure vessel with a large height, the telescopic rod 603 can be used to spray paint at a higher position, thereby improving the uniformity of spraying paint and simplifying the operation. During the painting process, hold the grip 504 with your right hand, adjust the length of the pull rope 810 according to the distance that the telescopic rod 603 extends outward, and then buckle the pull ring at the bottom of the pull rope 810 with your index finger. Since the pull rope 810 changes direction through the two guide rings 809 on the telescopic rod 603, in a static state, the first drive rod 802 slides to the top of the guide bar 801 under the reset action of the fourth spring 803, and conflicts with the second guide rod 702. At the same time, the roller 807 at the other end of the first drive rod 802 is located at the bottom of the second slide groove 806. Then, during the painting process, pull the pull rope 810. Since the other end of the pull rope 810 is connected to the docking rod 808, it drives the docking rod 808 to the guide ring 80 9, the docking rod 808 drives the first driving rod 802 to move in the direction of the end of the guide bar 801, and drives the roller 807 to roll in the second slide groove 806, and the guide plate 805 rotates a certain angle around the second guide rod 702 until the bottom surface of the first driving rod 802 hits the limiting column 706, and the pull rope 810 is continuously pulled. At this time, the first driving rod 802 continues to slide along the guide bar 801, and rotates a certain angle around the limiting column 706. The first driving rod 802 drives the second driving rod 804 at the end to hit the switch of the paint spray gun 9. At this time, the paint in the inner liner 207 can be sprayed outward through the paint spray gun 9, which solves the problem of difficulty in painting when the pressure vessel is at a high height, and improves the painting efficiency; After the painting operation is completed, the paint spray tube is rolled up, and then the pull bar 406 arranged on the side wall of the paint spray bucket body 1 is pulled upward, and then the pull bar 406 drives the second fixing clamp 405 to slide upward along the first guide rod 403 until the second fixing clamp 405 is completely offset from the first fixing clamp 402, and then the spray tube rolled into a circular ring is hung between the first fixing clamp 402 and the second fixing clamp 405, and then the pull bar 406 is loosened, and the second fixing clamp 405 is driven to slide downward and clamp the spray tube under the reset action of the tension spring 404. When it is not used for a long time, the knob 408 above the connecting frame 401 is rotated to drive the resistance rod 407 at the bottom to resist the second fixing clamp 405, so that the second fixing clamp 405 can be effectively limited to prevent the spray tube from falling off from the equipment during transportation, and the stability is strong; Then install the paint spray gun 9 on the sealing cover 206, just align the protrusion on the grip rod 504 with the groove on the mounting seat 501, and then snap the bottom end of the grip rod 504 into the center position of the mounting seat 501. In the process of inserting the grip rod 504, the bottom cover 505 at the bottom end of the grip rod 504 first hits the limit block 502, so that the limit block 502 slides toward the inside of the mounting seat 501 until the grip rod 504 is completely inserted into the mounting seat 501. At the same time, the limit block 502 slides outward along the inner wall of the mounting seat 501 under the reset action of the first spring 503 and snaps into the grip rod 504. The grip 504 and the paint spray gun 9 can be installed on the equipment by fitting the limiting groove 507 on the grip 504 and the paint spray gun 9 to avoid the problem of the paint spray gun 9 falling and being damaged when the equipment is moved. When the grip 504 and the paint spray gun 9 need to be removed, it is only necessary to press the telescopic rod 603 downwards. The telescopic rod 603 drives the driving block 508 to slide downwards and compress the second spring 509. At the same time, the protrusion at the edge of the driving block 508 slides downwards along the first slide groove 506 and contacts the limiting block 502, so that the limiting block 502 is no longer engaged with the limiting groove 507. At this time, the grip 504 can be pulled out from the mounting seat 501, which is easy to operate.
