Description

Technical Field

[0001] The present invention relates to the technical field of surface treatment, and particularly to an intelligent integrated device for grinding and spraying. Background Art

[0002] Grinding is a common method for treating impurities on metal pipes (including the inner wall of the pipes). Through physical grinding methods, such as using tools like sandpaper and steel wool, the surface of the metal pipes can be ground. At the same time, rust prevention treatment should be carried out in a timely manner after grinding, such as spraying rust inhibitors or sealants. Additionally, depending on the construction environment of the pipes, it is sometimes necessary to spray anti-corrosion agents on the pipes;

[0003] Currently, during the production process of pipes, the grinding and spraying operations on the inner wall of the pipes are interfered by the narrow working environment, making it difficult to carry out the grinding and spraying treatment on the inner wall of the pipes. It is impossible to accurately perform surface treatment on the pipes, which affects the subsequent stable operation of the pipes.

[0004] Referring to a grinding and spraying device disclosed in the patent application with the publication number CN116673842A, this spraying device integrates a grinding device and a spraying device, and can orderly perform grinding, adsorption, and spraying steps, ensuring that the workpiece can be immediately sprayed after grinding, with good practicability and reliability in use.

[0005] Currently, there are some devices on the market that integrate grinding and spraying designs. For example, the above-mentioned grinding and spraying device also combines a grinding device and a spraying device for construction. Although the construction efficiency is improved, during the grinding and spraying construction of the above-mentioned grinding and spraying device, no continuous dynamic isolation treatment is carried out on the construction environment. Limited by the construction environment, the spread of dust in the grinding environment is extremely likely to interfere with subsequent spraying, and the remaining dust is extremely likely to affect the subsequent spraying effect, affecting the spraying accuracy of the inner wall of the pipes and increasing the rework rate;

[0006] At the same time, the above-mentioned grinding and spraying device requires external equipment to control the grinding rate and cannot adapt the traveling speed according to its own grinding speed, increasing the control difficulty, being unfavorable for the rapid and stable operation of grinding and spraying work, and increasing the construction difficulty.

[0047] Compared with the prior art, the beneficial effects of the present invention are:

[0048] In the present invention, an isolation part is arranged on the traveling part, and the isolation part can complete dynamic cooperation with the extrusion part of the grinding unit, so that the isolation part can be in an expanded state during the operation state to complete effective isolation operation, separating the working areas of the grinding unit and the spraying unit, optimizing the construction environment, avoiding mutual interference.

[0050] In the present invention, by providing a grinding unit, the grinding roller of the grinding member is controlled to contact the inner wall of the processing pipeline. When the grinding roller rotates for grinding, through the meshing transmission of the third gear and the fourth gear, the rotating cleaning roller can clean the grinding roller. At the same time, the dust generated during the grinding process is filtered by the circular filter cartridge for dust impurities, and the dust is transferred to the outside through the conveying pipeline for centralized collection. Based on the fact that the circular filter cartridge can rotate in the circular channel, when the friction bumps and the friction ring are in frictional transmission, the circular filter cartridge rotates accordingly, which can change the contact position between the circular filter cartridge and the conveying channel, avoid the problem of impurity blockage affecting the air volume, and reduce the maintenance frequency.

[0069] Embodiment 1: The present invention provides a technical solution: As Figure 1 , Figure 2As shown, an intelligent grinding and spraying integrated equipment includes a walking part, which includes two symmetrically arranged annular parts 1, a center plate is installed in the middle position of the two annular parts 1, and module seats are arranged in a circular array between the inner sides of the two annular parts 1 and the center plate, and a screw nut is slidably installed on each module seat, and a plurality of positive and negative threaded screws 2 are arranged in a circular array between the two annular parts 1, and each positive and negative threaded screw 2 rotates through the center plate, and each positive and negative threaded screw 2 is driven through the corresponding screw nut to complete power transmission, and a plurality of No. 1 arms 3 and No. 2 arms 4 are respectively hingedly arranged in a circular array on the two annular parts 1, and each No. 1 arm 3 and No. 2 arm 4 is rotatably provided with a walking wheel. 5, each screw nut is hinged with a support arm, and the multiple support arms are hinged with the first arm 3 and the second arm 4 respectively, and the corresponding two screw nuts are synchronously controlled to move closer to or farther from each other through the positive and negative thread screws 2, and the first arm 3 and the second arm 4 are synchronously pushed to move by the support arms when the corresponding two screw nuts are closer to or farther from each other, and an annular inner gear ring 7 is coaxially arranged on one side of one of the ring members 1, and an outer gear ring is arranged on the outer wall of the annular inner gear ring 7, and a first gear 8 meshing with the annular inner gear ring 7 is fixedly sleeved at one end of each positive and negative thread screw 2, and a driving motor is installed on one side of one of the ring members 1, and a second gear meshing with the outer gear ring is arranged at the output end of the driving motor, and further comprising:

[0070] The center retaining ring 9 is arranged at the middle position of the walking member to complete the isolation operation. The center retaining ring 9 is fixedly arranged concentrically with the center plate. An adjusting arm 6 is rotatably penetrated at the center of the center retaining ring 9. An isolating member for isolation is detachably installed on the center retaining ring 9. A driving member is provided on the center retaining ring 9 and the adjusting arm 6.

[0071] A spraying unit, arranged at one end of the adjusting arm 6 for spraying operation;

[0072] The grinding unit is arranged at the other end of the adjusting arm 6 for grinding operation. The grinding unit cooperates with the driving member to complete the adaptive movement of the walking member. The grinding unit includes a grinding member, an extrusion member and an adsorption member. The grinding member is used to complete the grinding work. The extrusion member is arranged at the bottom of the grinding member to maintain its dynamic stability. The extrusion member controls the expansion of the isolation member to complete the blocking. The adsorption member is arranged on the grinding member to complete the adsorption and purification of smoke;

[0073] It should be noted that: when the walking part is adapted and adjusted: by providing a walking part, starting the drive motor, the annular inner gear ring 7 is driven to rotate via the No. 2 gear, and the multiple positive and negative screw rods 2 are synchronously controlled to rotate, so that the two screw nuts corresponding to the multiple positive and negative screw rods 2 move away from each other, and through the push of the support arm, the No. 1 arm 3 and the No. 2 arm 4 are synchronously unfolded until the walking wheel 5 contacts the inner wall of the processing pipe. The multiple No. 1 arms 3 and the No. 2 arms 4 on the walking part can be synchronously controlled, and the reset operation can be completed by subsequently controlling the driving motor to reverse, which is convenient to operate.

[0074] Among them, electrical components such as the drive motor, electric push rod, and control motor are all connected to switches through wires, and the switches are electrically connected to a controller. The specific structure of the controller is not limited. Absolute encoders are installed on both the drive motor and the control motor for accurately positioning the drive motor and the control motor.

[0075] Embodiment 2: Based on the separator provided in Embodiment 1, this embodiment provides a further technical solution for the separator.

[0076] As Figure 4 and Figure 5 shown, the separator includes:

[0077] An annular baffle 29 is detachably arranged on the central retaining ring 9, and the annular baffle 29 is detachably connected to the central retaining ring 9 specifically by quick-release parts, bolts, etc. The size of the annular baffle 29 is replaced with different sizes according to the actual construction pipe diameter for use;

[0078] An annular airbag 30 is sleeved outside the annular baffle 29. A wear-resistant layer is provided on the surface of the annular airbag 30, and the annular airbag 30 is communicated with the extrusion chamber 19 of the extrusion member through a pipeline. The annular airbag 30 is controlled by the extrusion member to expand to complete dynamic sealing;

[0079] It should be noted that when the separator is dynamically controlled: by providing the separator, first, the annular baffle 29 with different diameters is replaced according to the size of the processing pipeline. Specifically, the annular baffle 29 is assembled on the central retaining ring 9. Due to the cooperative setting of the separator and the grinding member, when the grinding roller 15 contacts the inner wall of the processing pipeline, first, the grinding roller 15 applies a force to the extrusion plate 20. Through the extrusion plate 20, the medium temporarily stored in the extrusion chamber 19 is sent into the annular airbag 30, and the annular airbag 30 is controlled to expand and be in sealed contact with the processing pipeline, thereby completing a stable dynamic isolation operation, avoiding interference of dust on the spraying work area. At the same time, under the control of the first spring 22, the grinding roller 15 contacts the inner wall of the processing pipeline with a certain pressure, ensuring the consistency of grinding and avoiding the problem of poor grinding uniformity. Designed in this way, the grinding roller 15 can be dynamically cooperated with the annular airbag 30, can provide a stable pressing force for the grinding roller 15, and can control the annular airbag 30 to maintain a certain expansion amount. The two cooperate with each other, enabling the grinding and spraying processing to be carried out safely and stably, which is beneficial to construction.

[0080] Embodiment 3: Based on the grinding unit provided in Embodiment 1, this embodiment provides a further technical solution for the grinding unit.

[0081] As Figure 3 、 Figure 7 shown, the adjusting arm 6 includes:

[0082] The central axis 10 is concentrically arranged on the central retaining ring 9, and the central axis 10 rotates through the central plate of the walking part. Adjustment areas are provided at both ends of the central axis 10;

[0083] Two extension arms 11 are symmetrically and slidably engaged into the two adjustment areas. A plurality of positioning holes are arranged side by side on each extension arm 11, and positioning bolts are inserted through the ends of the two extension arms 11. The two positioning bolts correspondingly pass through the positioning holes to limit the extension arms 11 on the adjustment areas;

[0084] Two telescopic frames 12 are correspondingly arranged at the tails of the two extension arms 11. A telescopic arm 13 is slidably arranged in each telescopic frame 12, and an electric push rod for controlling the telescopic movement of the telescopic arm 13 is arranged in each telescopic frame 12;

[0085] As Figure 6 and Figure 8 shown, in the embodiment of the present invention, the grinding part includes:

[0086] A grinding base 14 is arranged above one end of the adjusting arm 6, and the top of the grinding base 14 is open. A grinding roller 15 is rotatably installed in the grinding base 14. A third gear 16 is fixedly sleeved at one end of the grinding roller 15, and a grinding motor drivingly connected to the grinding roller 15 is arranged on the grinding base 14;

[0087] A cleaning roller 17 is rotatably arranged in the grinding base 14, and the cleaning roller 17 is in rotational contact with the top of the grinding roller 15 to complete cleaning. A fourth gear 18 meshing with the third gear 16 is fixedly sleeved at one end of the cleaning roller 17;

[0088] It should be noted that during the grinding process: by providing a grinding unit, first, the extension distance of the extension arm 11 is freely adjusted according to the processing environment, and then the electric push rod is started to control the extension length of the telescopic arm 13, so that the grinding roller 15 of the grinding part contacts the inner wall of the processing pipeline. As the grinding roller 15 rotates, the grinding of the processing pipeline is completed. When the grinding roller 15 rotates for grinding, through the meshing transmission of the third gear 16 and the fourth gear 18, the cleaning roller 17 rotates synchronously. With the rotating cleaning roller 17, the grinding roller 15 can be cleaned, ensuring the cleanliness of the grinding roller 15. At the same time, the dust generated during the grinding process is centrally collected through the suction nozzle 23. Then, the dust impurities enter the circular channel 24, and the circular filter cartridge 25 filters the dust impurities. The dust is transferred to the outside through the conveying pipeline for centralized storage. Based on the fact that the circular filter cartridge 25 can rotate in the circular channel 24, when the grinding roller 15 rotates, the cleaning roller 17 and the trigger ring are synchronously driven to rotate. With the design of the friction bumps 28, during the rotation of the trigger ring, it can intermittently contact the friction ring 26. When the friction bumps 28 and the friction ring 26 are in frictional transmission, the circular filter cartridge 25 rotates, which can change the contact position between the circular filter cartridge 25 and the conveying channel 27, avoiding the problem of impurity blockage affecting the air volume, ensuring the stability of dust purification, and reducing the maintenance frequency;

[0089] The extrusion part includes:

[0090] An extrusion chamber 19 is arranged below the grinding part, and the top is open. A certain amount of medium is injected into the extrusion chamber 19.

A first spring 22 is sleeved outside the two guide rods 21 correspondingly. The two first springs 22 are arranged between the extrusion plate 20 and the extrusion chamber 19 for resetting;

[0092] Such as Figure 9 and Figure 10 As shown, in the embodiment of the present invention, the adsorbing part includes:

[0093] A suction nozzle 23 is arranged on one side of the inner top of the grinding base 14 for adsorption;

A control motor in transmission connection with the driving gear 32 is arranged on the central plate of the walking member through a bracket;

[0102] It should be noted that: when performing circumferential grinding and spraying: after the grinding roller 15 and the spray pipe 46 move to the predetermined position, the control motor is started. Through the meshing transmission of the driving gear 32 and the sensing gear ring 31, the central axis 10 performs circumferential rotation. Since both ends of the adjusting arm 6 are respectively connected to the grinding unit and the spraying unit, the grinding unit and the spraying unit are synchronously driven to perform circumferential rotation processing, improving the processing efficiency and optimizing the construction process;

[0103] A pushing ring 33 is fixedly sleeved on the central axis 10 of the adjusting arm 6 through a bracket. An extrusion boss 34 protrudes from the pushing ring 33.

[0104] The trigger chamber 37 is arranged on the central plate of the walking member, and the top of the trigger chamber 37 is open. A certain amount of medium is injected into the trigger chamber 37. The medium is specifically one of hydraulic oil and gas. A piston member 38 is slidably and sealingly installed in the trigger chamber 37. The piston member 38 is composed of a piston plate and a piston rod. The piston plate is slidably and sealingly arranged in the trigger chamber 37, and the piston rod is integrally and fixedly arranged on the piston plate. The front end of the piston member 38 is rotatably connected to the roller 36 through a bracket;

[0105] The second spring 39 is arranged between the piston member 38 and the trigger chamber 37, and the piston member 38 is controlled to move back to its original position through the second spring 39;

[0106] The driving member further includes:

[0107] The traveling gear 40 is arranged on one of the traveling wheels 5 of the traveling member.

[0111] It should be noted that when controlling the walking part: by providing a driving part and adopting the design of the extrusion boss 34, the central shaft 10 synchronously drives the pushing ring 33 to rotate during the circumferential rotation. Moreover, the extrusion boss 34 is on the same horizontal line as the grinding roller 15 and the spray pipe 46. Therefore, after the grinding roller 15 and the spray pipe 46 complete one processing in the circular direction, the extrusion boss 34 acts synchronously. Through the transmission of the roller 36 and the walking track 35, the piston part 38 is extruded, causing the piston part 38 to extend in the trigger chamber 37 for suction, guiding the medium in the pushing chamber 42 into the trigger chamber 37, hiding the pushing rack 44 into the pushing chamber 42. In this action, the one-way bearing 41 is in the unlocked state, so the walking wheel 5 does not rotate. Then, when the pushing ring 33 continues to rotate, the roller 36 slides from the extrusion boss 34 onto the pushing ring 33, causing the piston part 38 to move in the trigger chamber 37 for pushing, pushing the medium in the trigger chamber 37 into the pushing chamber 42, gradually extending the pushing rack 44. At this time, the one-way bearing 41 is in the locked state, causing the walking wheel 5 to rotate, controlling the walking part, the grinding unit, and the spraying unit to move forward as a whole. It can complete the overall movement control based on a single circular processing of the grinding unit and the spraying unit, reducing the control difficulty, being able to automatically complete the walking processing, and the walking amount can be adaptively adjusted according to the width of the extrusion boss 34, enabling the device to move and walk autonomously according to the grinding speed and fully perform comprehensive grinding treatment, greatly reducing the construction difficulty;

[0112] In an embodiment of the present invention, the spraying unit includes:

[0113] The spray pipe 46 is arranged above one end of the adjusting arm 6, and a feed pipe is arranged on one side of the spray pipe 46. The feed pipe communicates with the spraying agent through a pipeline, and the spray pipe 46 is specifically detachably and fixedly connected to the top of the telescopic arm 13;

[0114] A plurality of nozzles 47 are arranged on the spray pipe 46 in parallel at intervals;

[0115] It should be noted that when performing spraying treatment: by providing the spraying unit, first, the extension distance of the extension arm 11 is freely adjusted according to the processing environment, and then the electric push rod is started to control the extension length of the telescopic arm 13, so that the spray pipe 46 maintains a certain distance from the processing pipeline. Subsequently, the spraying material is sent into the spray pipe 46, and the coating is evenly sprayed onto the inner wall of the processing pipeline through a plurality of nozzles 47. It can organically combine grinding and spraying, improve the construction efficiency, and there is no need to repeatedly replace different devices for construction, greatly reducing the construction difficulty.

[0116] The present invention provides an intelligent integrated device for grinding and spraying. The specific working principle is as follows: First, the walking part is pushed into one end of the processing pipeline waiting for grinding and spraying. Then, the walking part is controlled to expand until the walking wheels 5 contact the inner wall of the processing pipeline. Then, the two adjusting arms 6 are controlled so that the grinding units and spraying units provided at both ends thereof are synchronously moved to predetermined positions. By providing a separator on the walking part, and the separator can complete dynamic cooperation with the pressing part of the grinding unit, so that the separator can be in an expanded state during the operation state to complete effective isolation operation, separating the working areas of the grinding unit and the spraying unit, optimizing the construction environment and avoiding mutual interference. At the same time, the design of the pressing part can complete the flexible control of the grinding part, so that the grinding part contacts the processing pipeline with a predetermined pressure, ensuring the grinding consistency. By providing an adsorbing part, the dust generated by grinding can be fully adsorbed and purified, avoiding the spread of dust and improving the construction environment. At the same time, by providing a driving part, when the grinding part grinds in a circular rotation manner, after the single-cycle grinding of the grinding part is completed, the driving part is controlled to act, and the driving part provides a quantitative driving distance for the walking part, so that the whole walking part obtains mobile walking. With such a design, the walking speed of the walking part can be organically combined with the grinding speed of the grinding part, improving the overall precision of grinding and spraying, avoiding the problem of missing grinding and spraying, optimizing the construction steps, reducing the control difficulty at the same time, and being able to autonomously complete the grinding and spraying processing in the self-walking state, improving the construction precision.
