Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and particularly relates to a spraying device. Background Art

[0002] Chimneys are generally used for flue gas emissions. During the emission process, various corrosive gases and high temperatures will act, and these factors will gradually erode the inner wall materials, resulting in a decrease in the structural strength and stability of the chimney, thus affecting its long-term use safety and efficiency. Nowadays, corresponding anti-corrosion measures are usually taken to protect the inner wall. For example, anti-corrosion coatings are applied to the inner wall of the chimney to extend the service life of the chimney and ensure that the chimney can stably undertake the function of discharging waste gas. When carrying out anti-corrosion construction on the inner wall of the chimney, it is necessary to ensure that the coating thickness is consistent at all parts of the inner wall of the chimney. A thinner coating thickness will affect the anti-corrosion effect, and a thicker coating thickness will increase the cost and slow down the drying and curing speed compared to the surface, thus generating internal stress and causing the coating to crack or peel off. The prior art usually uses a hoisting device to hoist the spraying equipment into the chimney for spraying treatment. The hoisting method is likely to cause the spraying equipment to shake, resulting in the spraying position of the nozzle being erratic, thus affecting the spraying uniformity. Moreover, due to the different shapes of chimneys, which are usually wider at the bottom and narrower at the top, if a horizontal support structure is set on the spraying equipment, it is difficult to well adapt to different chimneys for spraying. Therefore, how to set up a spraying device that can spray evenly and at the same time adapt to different-shaped chimneys has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0003] The purpose of the present invention is to address the above deficiencies and provide a spraying device that can evenly spray anti-corrosion coatings on the inner wall of the chimney and at the same time adapt to different-shaped chimneys.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: A spraying device, comprising:

[0005] A guiding component, on which a hoisting device is arranged. The guiding component can be installed on the top of the chimney and can drive the hoisting device to move in the horizontal plane;

[0006] A lifting rope, which is wound around the moving end of the hoisting device. One end of the lifting rope away from the hoisting device is connected to a spraying component. The hoisting device can cooperate with the lifting rope to hoist the spraying component from top to bottom into the chimney, and the spraying component can spray the coating onto the inner wall of the chimney;

[0007] A loading and unloading mechanism, which is arranged at the moving end of the guiding component and includes a transfer component, a disassembly and assembly component, and a storage component. The transfer component can be turned back and forth between the horizontal and vertical directions. The storage component stores at least two positioning sleeves. The positioning sleeve is hollow inside, has external threads at one end and internal threads that match them at the other end;

[0008] In the initial state, a vertical positioning sleeve is provided on the spraying assembly; the transfer assembly can be flipped to a horizontal state to dock with the storage assembly, receive the positioning sleeve output by the storage assembly, and drive the positioning sleeve thereon to flip to a vertical state together, and make the positioning sleeve located below the disassembly and assembly assembly and above the spraying assembly, and coaxially aligned with the positioning sleeve on the spraying assembly. The disassembly and assembly assembly can drive the positioning sleeve in the vertical state on the transfer assembly to rotate and move downward to dock and screw with the positioning sleeve on the spraying assembly to form an integral body with the positioning sleeve on the spraying assembly.

[0009] Further, the transfer assembly includes a machine base provided at the moving end of the guiding assembly. A carrying platform is rotatably provided on the machine base. The machine base can drive the carrying platform to flip back and forth between the horizontal and vertical directions. When the carrying platform is in the horizontal state, it can be aligned with the input end or the output end of the storage assembly. When the carrying platform is in the vertical state, it is located at the bottom of the moving end of the disassembly and assembly assembly. A first electric clamp is provided on the carrying platform, and the first electric clamp can clamp the positioning sleeve when the positioning sleeve in the storage assembly moves onto the carrying platform.

[0010] Further, the disassembly and assembly assembly includes a first linear module vertically provided at the moving end of the guiding assembly. An installation plate is provided at the moving end of the first linear module. The first linear module can drive the installation plate to move up and down. A disassembly and assembly device is provided on the installation plate. A second electric clamp is provided on the lower side of the first linear module, and the second electric clamp can clamp and fix the corresponding positioning sleeve on the spraying assembly; the disassembly and assembly device can, when the carrying platform rotates to the vertical state, cooperate with the first linear module to drive the positioning sleeve on the carrying platform to rotate and descend.

[0011] Further, the storage component includes a second linear module disposed at the moving end of the guiding component. A storage frame is provided at the moving end of the second linear module. The second linear module can drive the storage frame to move up and down. Feeding and discharging ports are respectively formed through the upper and lower sides of the corresponding end of the storage frame. The feeding and discharging ports include a feeding port disposed above and a discharging port disposed below. An inclined guiding plate is further provided on the storage frame. There are at least two guiding plates which are distributed vertically, and their inclined directions are staggered. A gap for the positioning sleeve to pass through is formed between the downward side of each guiding plate and the storage frame. The feeding and discharging ports can cooperate with the guiding plates to enable each positioning sleeve to enter and exit the storage frame in sequence. A control console is provided on one side of the storage frame close to the transfer component. Two relatively rotatable conveying rollers are provided on the control console. When the carrying platform rotates to the horizontal state, the positioning sleeve thereon is located between the two conveying rollers. A cylinder is provided on the side of the storage frame far from the transfer component. When the conveying rollers, the cylinder and the feeding and discharging ports are on the same axis, the cylinder can extend into the feeding and discharging port to push one end of the positioning sleeve to the conveying rollers and enter the carrying platform under the drive of the conveying rollers.

[0012] Further, an electromagnet is provided at the moving end of the cylinder, and the positioning sleeve can be magnetically attracted by the electromagnet.

[0013] Further, the positioning sleeve is a polygonal sleeve body.

[0014] Further, the guiding component includes a first linear slide and a second linear slide. An installation frame is provided at the moving end of the second linear slide.

A pump body is provided at the bottom of the connecting frame. No less than six spray heads are provided at the output end of the pump body.

[0016] The beneficial effects of the present invention are embodied in:

[0017] In the present invention, a guide assembly is installed on the top of the chimney, which can drive the lifting equipment to move horizontally to the center of the chimney where the spraying assembly is located. Subsequently, the spraying assembly is controlled by the lifting equipment to move downward in the chimney so as to spray paint on the inner walls of the chimney at different heights. During the movement, the loading and unloading mechanism is driven to work. Specifically, when the transfer assembly is in a horizontal state, it can cooperate with the storage assembly to take out the positioning sleeves inside it in turn. During this process, whenever the transfer assembly drives the corresponding positioning sleeve to rotate to a vertical state, the positioning sleeve on the transfer assembly is located at the bottom of the disassembly assembly, and the disassembly assembly can drive the positioning sleeve to rotate and descend. At this time, the first positioning sleeve will be installed on the spraying assembly, and the remaining adjacent positioning sleeves are screwed together to form a vertical and non-rotatable long tubular structure, so that the spraying assembly will not change the distance from the inner wall of the chimney due to shaking when spraying the paint. At the same time, since the device can be used without using a support structure that laterally interferes with the inner wall of the chimney, it can evenly spray anti-corrosion paint on the inner walls of chimneys of different shapes.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-8 , the present invention discloses a spraying device, including a guiding component, on which a hoisting device is arranged. The guiding component can be hoisted by a crane and installed on the top of the chimney, and the guiding component can drive the hoisting device to move in the horizontal plane. A suspension rope 4 is wound around the moving end of the hoisting device. One end of the suspension rope 4 away from the hoisting device is connected to a spraying assembly 5. The hoisting device can cooperate with the suspension rope 4 to hoist the spraying assembly 5 from top to bottom into the chimney, and the spraying assembly 5 can spray paint onto the inner wall of the chimney.

[0030] In one embodiment, a loading and unloading mechanism is arranged at the moving end of the guiding component. The loading and unloading mechanism includes a transfer assembly 6, a disassembly and assembly component 7, and a storage component 8. The transfer assembly 6 can be turned back and forth between the horizontal and vertical directions. At least two positioning sleeves 9 are stored in the storage component 8. The positioning sleeve 9 is hollow inside, with external threads at one end and internal threads matching therewith at the other end. In the initial state, a vertical positioning sleeve 9 is arranged on the spraying assembly 5. The transfer assembly 6 can be turned to the horizontal state to dock with the storage component 8, receive the positioning sleeve 9 output by the storage component 8, and drive the positioning sleeve 9 thereon to turn to the vertical state together, and make the positioning sleeve 9 located below the disassembly and assembly component 7 and above the spraying assembly 5, and coaxially aligned with the positioning sleeve 9 on the spraying assembly 5. The disassembly and assembly component 7 can drive the vertical positioning sleeve 9 on the transfer assembly 6 to rotate and move downward to dock and screw with the positioning sleeve 9 on the spraying assembly 5 to form an integral body with the positioning sleeve 9 on the spraying assembly 5.

[0031] In a specific implementation, the guide assembly is installed on the top of the chimney, which can drive the lifting equipment to move horizontally to the center of the chimney where the spray assembly 5 is located. Subsequently, the spray assembly 5 is controlled to move downward in the chimney through the lifting equipment, so as to spray paint on the inner wall of the chimney at different heights. During the movement, the loading and unloading mechanism is driven to work. Specifically, when the transfer assembly 6 is in a horizontal state, it can cooperate with the storage assembly 8 to take out the positioning sleeves 9 inside it in turn. During this process, whenever the transfer assembly 6 drives the corresponding positioning sleeve 9 to rotate to a vertical state, the transfer assembly The positioning sleeve 9 on 6 is located at the bottom of the disassembly and assembly component 7, and the disassembly and assembly component 7 can drive the positioning sleeve 9 to rotate and descend. At this time, the first positioning sleeve 9 will be installed on the spraying component 5, and the remaining adjacent positioning sleeves 9 are screwed together to form a vertical and non-rotatable long tubular structure, so that the spraying component 5 will not change the distance from the inner wall of the chimney due to shaking when spraying paint. At the same time, since the device can be used without using a supporting structure that laterally resists the inner wall of the chimney, it can evenly spray the anti-corrosion paint on the inner walls of chimneys of different shapes.

[0032] In addition, according to the height of the chimney and the spraying range of the spraying component 5, the spraying component 5 can be controlled to descend a corresponding number of times in the chimney, and the height of each descent is the same. It will stop temporarily after descending a corresponding height, and the spraying component 5 will spray when it stops; when the device needs to be recovered, the transfer component 6 can be controlled to rotate to a vertical state. When the lifting device recovers the spraying component 5 upward, the corresponding positioning sleeve 9 will rise to the transfer component 6 synchronously. At this time, the positioning sleeve 9 can be removed from the spraying component 5 or the remaining positioning sleeves 9 at the bottom through the reverse operation of the disassembly and assembly component 7. After removal, it is clamped by the transfer component 6 and driven to rotate to a horizontal state. Then, it can be stored in the storage component 8 in cooperation with the storage component 8. The above operations can be repeated many times to remove and store each positioning sleeve 9, which is convenient for recycling.

[0033] In one embodiment, the transfer component 6 includes a base 61 arranged at the moving end of the guide component, and a support platform 62 is rotatably mounted on the base 61. The base 61 can drive the support platform 62 to flip back and forth between the horizontal and vertical directions, so that the support platform 62 rotates to a horizontal state or a vertical state. When the support platform 62 is in the horizontal state, it can be aligned with the input end or the output end of the storage component 8. When the support platform 62 is in the vertical state, it is located at the bottom of the moving end of the disassembly and assembly component 7. A first electric clamp 63 is arranged on the support platform 62, and the first electric clamp 63 can clamp the positioning sleeve 9 in the storage component 8 when it moves to the support platform 62.

[0034] In specific implementation, a motor device for driving the rotation of the carrier 62 is installed on the machine base 61. When the carrier 62 rotates to align with the output end of the storage component 8, it can cooperate with the storage component 8 to sequentially take out each positioning sleeve 9 inside it. When the corresponding positioning sleeve 9 is located on the carrier 62, the first electric clamp 63 can be controlled to start and clamp it. After clamping, the carrier 62 rotates and can very stably drive the positioning sleeve 9 to the vertical state. At this time, the moving end of the disassembly and assembly component 7 is located at the top of the positioning sleeve 9. By driving the moving end of the disassembly and assembly component 7 to continuously descend and rotate, its moving end will be screwed into the top of the positioning sleeve 9 in a spiral manner. At this time, first control the moving end of the disassembly and assembly component 7 not to rotate but to continuously descend. At this time, the positioning sleeve 9 synchronously descends until it contacts the spraying component 5 or the corresponding positioning sleeve 9 located at its bottom. At this time, control the moving end of the disassembly and assembly component 7 to continue to descend and release the first electric clamp 63. The positioning sleeve 9 continuously rotates and descends and will be screwed into the spraying component 5 or the other positioning sleeve 9 located at its bottom. After installation is completed, control the disassembly and assembly component 7 to clamp the positioning sleeve 9 so that it cannot rotate. Subsequently, control the moving end of the disassembly and assembly component 7 to reverse and rise to separate it from the corresponding positioning sleeve 9, thereby completing the installation of a single positioning sleeve 9. By repeating the operation in the above manner, each positioning sleeve 9 can be installed.

[0035] In one embodiment, the disassembly and assembly component 7 includes a first linear module 71 vertically arranged at the moving end of the guiding component. The moving end of the first linear module 71 is equipped with a mounting plate 72. The first linear module 71 can drive the mounting plate 72 to move up and down. A disassembly and assembly device 73 is installed on the mounting plate 72. A second electric clamp 74 is installed on the lower side of the first linear module 71. The second electric clamp 74 can clamp and fix the corresponding positioning sleeve 9 on the spraying component 5 when the spraying component 5 is in the spraying state. The disassembly and assembly device 73 can, when the carrier 62 rotates to the vertical state, cooperate with the first linear module 71 to drive the positioning sleeve 9 on the carrier 62 to rotate and descend.

[0036] In specific implementation, the disassembly and assembly device 73 includes a motor device and a threaded column installed at the moving end of the motor device. The threaded column is matched with the corresponding internal thread of the positioning sleeve 9. By driving the disassembly and assembly device 73 to descend and rotate through the first linear module 71, it can be screwed into the corresponding internal thread of the corresponding positioning sleeve 9 in a spiral manner; or when the second electric clamp 74 clamps the corresponding positioning sleeve 9, drive the disassembly and assembly device 73 to rise and reverse, so that the corresponding positioning sleeve 9 can be separated from the disassembly and assembly device 73. And when the spraying component 5 is in the spraying state, by clamping through the corresponding positioning sleeve 9 on the spraying component 5, the spraying component 5 can be kept stable without shaking.

[0037] And the above-mentioned electric clamp belongs to the common knowledge in the field, so the specific structure and working principle thereof will not be elaborated too much in this text.

[0038] In one embodiment, the storage component 8 includes a second linear module 81 vertically arranged at the moving end of the guiding component. A storage frame 82 is installed at the moving end of the second linear module 81. The second linear module 81 can drive the storage frame 82 to move up and down. Feeding and discharging openings 83 are respectively formed through the upper and lower sides of the corresponding end of the storage frame 82 corresponding to the transfer component 6. The feeding and discharging openings 83 include a feeding port arranged above and a discharging port arranged below. An inclined guiding plate 84 is also installed on the storage frame 82. There are at least two guiding plates 84 which are distributed up and down, and their inclined directions are staggered with each other. A gap for the positioning sleeve 9 to pass through is formed between the downward side of each guiding plate 84 and the storage frame 82. The feeding and discharging openings 83 can cooperate with the guiding plates 84 to enable the positioning sleeves 9 to enter and exit the storage frame 82 in sequence. A control console 85 is arranged on one side of the storage frame 82 close to the transfer component 6. Two relatively rotatable conveying rollers 86 are installed on the control console 85. When the bearing platform 62 rotates to the horizontal state, the positioning sleeve 9 thereon is located between the two conveying rollers 86. A cylinder 87 is arranged on the side of the storage frame 82 far from the transfer component 6. When the conveying rollers 86, the cylinder 87 and the feeding and discharging openings 83 are on the same axis, the cylinder 87 can extend into the feeding and discharging openings 83 to push one end of the positioning sleeve 9 to the conveying rollers 86 and enter the bearing platform 62 under the drive of the conveying rollers 86.

[0039] In one embodiment, an electromagnet 88 is installed at the moving end of the cylinder 87, and the positioning sleeve 9 can be magnetically attracted by the electromagnet 88.

[0040] In specific implementation, when it is necessary to sequentially take out the positioning sleeves 9 in the storage frame 82, the storage frame 82 is controlled to rise until the feeding and discharging openings 83 in the output direction of the guiding plate 84 are aligned with the bearing platform 62, the cylinder 87 and the conveying rollers 86. At this time, the cylinder 87 and the conveying rollers 86 are driven to work. The telescopic shaft of the cylinder 87 extends out and pushes the outermost positioning sleeve 9 in the output direction of the guiding plate 84 out of the storage frame 82. At this time, one end of the positioning sleeve 9 far from the cylinder 87 will move between the two conveying rollers 86. By driving the two conveying rollers 86 to rotate relatively, it can continue to move until it reaches the bearing platform 62 in the horizontal state. After the above-mentioned positioning sleeve 9 leaves the storage frame 82, the remaining positioning sleeves 9 are supplemented by the inclination guidance of the guiding plate 84 to facilitate the subsequent repetition of the above steps for transmission;

[0041] When each positioning sleeve 9 outside the storage frame 82 needs to be loaded in sequence, the storage frame 82 is controlled to descend until the feeding and discharging port 83 in the input direction of the guide plate 84 is aligned with the bearing table 62, the air cylinder 87, and the conveying rollers 86. At this time, the positioning sleeve 9 on the bearing table 62 in the horizontal state is located between the two conveying rollers 86. By driving the conveying rollers 86 to rotate, the positioning sleeve 9 is made to pass through the feeding and discharging port 83 and enter the storage frame 82. At this time, the telescopic shaft of the air cylinder 87 is controlled to extend and the electromagnet 88 is energized. When the positioning sleeve 9 moves into contact with the electromagnet 88, the electromagnet 88 can magnetically attract it. At this time, the telescopic shaft of the air cylinder 87 is controlled to retract, which will drive the positioning sleeve 9 to completely move into the storage frame 82, and at this time the positioning sleeve 9 is separated from the conveying rollers 86. After the movement is completed, the electromagnet 88 is powered off, the positioning sleeve 9 is released from the limit, and it is inclined and guided by the guide plate 84 to the output direction of the guide plate 84 for subsequent repetition of the above steps for transmission.

[0042] In one embodiment, the positioning sleeve 9 is a polygonal sleeve body, and there are a plurality of rounded corners on its outer wall.

[0043] With such a design, when the positioning sleeve 9 is clamped by the first electric clamp 63 or the second electric clamp 74, it cannot rotate, thus ensuring its stable operation. And because there are a plurality of rounded corners on the outer wall of the positioning sleeve 9, it will not stop when rolling on the guide plate 84, which is convenient for actual use.

[0044] In one embodiment, the guiding assembly includes two first linear slides 1. A second linear slide 2 is installed at the moving ends of the two first linear slides 1, and a mounting frame 3 is installed at the moving end of the second linear slide 2. The hoisting equipment, the transfer assembly 6, the disassembly and assembly assembly 7, and the storage assembly 8 are all installed on the mounting frame 3.

[0045] In specific implementation, the first linear slide 1 is temporarily installed on the top of the chimney in cooperation with corresponding fixing parts, and it can drive the second linear slide 2 to reciprocate in two lateral directions, and the second linear slide 2 can drive the mounting frame 3 to reciprocate in the other two lateral directions, so that the hoisting equipment can move to the center of the chimney. And the above-mentioned fixing parts can be installation structures such as bolts, or can be clamped and fixed by clamps. This fixing method belongs to the common knowledge in the art, so it will not be elaborated too much in this text.

[0046] In one embodiment, the spraying assembly 5 includes a connecting frame 51 installed on the suspension rope 4. The connecting frame 51 is detachably connected to the corresponding positioning sleeve 9. A threaded groove (not shown in the figure) is provided on the connecting frame 51, and the corresponding external thread of the positioning sleeve 9 is screwed and matched with the threaded groove. A pump body 52 is installed at the bottom of the connecting frame 51, and there are no less than six spray heads 53 at the output end of the pump body 52.

[0047] By installing a hose on the pump body 52, an anti-corrosion coating is externally connected to the hose. After the pump body 52 is started, the coating can be connected to each nozzle 53 and sprayed onto the inner wall of the chimney through each nozzle 53.

[0048] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0049] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0050] In addition, "a plurality of" means more than two.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
