Description

Technical Field

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

[0002] Grinding is a common method for dealing with impurities in metal pipes (including the inner wall of the pipe). The surface of the metal pipe can be polished by physical grinding, such as using sandpaper, steel wool and other tools. At the same time, anti-rust treatment should be carried out in time after grinding, such as spraying rust inhibitors or sealants. At the same time, it is sometimes necessary to spray anti-corrosion agents on the pipes according to the construction environment of the pipes; At present, in the pipeline production process, the grinding and spraying of the inner wall of the pipeline are disturbed by the narrow working environment, which makes the grinding and spraying of the inner wall of the pipeline very difficult, and it is impossible to fully and accurately treat the surface of the pipeline, affecting the subsequent stable operation of the pipeline.

[0003] A grinding and spraying equipment disclosed in a patent application with reference publication number CN116673842A integrates a grinding device and a spraying device, and can perform grinding, adsorption and spraying steps in an orderly manner, ensuring that the workpiece can be sprayed immediately after grinding, and has good practicality and reliability.

[0004] At present, there are some equipments on the market that integrate grinding and spraying, such as the above-mentioned grinding and spraying equipment, which also adopts the combination of grinding device and spraying device for construction. Although the construction efficiency is improved, the above-mentioned grinding and spraying equipment does not carry out continuous dynamic isolation treatment of the construction environment during grinding and spraying construction. Due to the limitation of the construction environment, the spread of smoke and dust in the grinding environment can easily interfere with the subsequent spraying, and the residual smoke and dust can easily affect the subsequent spraying effect, which affects the spraying accuracy of the inner wall of the pipeline and increases the rework rate. At the same time, the above-mentioned grinding and spraying equipment requires external equipment to control the grinding rate, and cannot adapt the travel speed according to its own grinding speed, which increases the control difficulty, is not conducive to the rapid and stable operation of grinding and spraying work, and increases the construction difficulty.

[0023] Embodiment 1: The present invention provides a technical solution: Figure 1 , Figure 2 As 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: 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. A spraying unit, arranged at one end of the adjusting arm 6 for spraying operation; 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; 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.

[0024] 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 the controller. The specific structure of the controller is not limited. Absolute encoders are installed on the drive motor and the control motor for accurate positioning of the drive motor and the control motor.

[0025] Embodiment 2: Based on the isolation element provided in Embodiment 1, this embodiment provides a further technical solution for the isolation element.

[0026] like Figure 4 and Figure 5 As shown, the isolation element comprises: The annular baffle 29 is detachably arranged on the central baffle ring 9, and the annular baffle 29 is detachably connected to the central baffle ring 9 by means of quick-release parts, bolts, etc. The size of the annular baffle 29 can be replaced with different sizes according to different actual construction pipe diameters; The annular airbag 30 is sleeved on the outside of the annular baffle 29. A wear-resistant layer is provided on the surface of the annular airbag 30. The annular airbag 30 is connected with the extrusion chamber 19 of the extrusion piece through a pipeline. The annular airbag 30 is expanded by the extrusion piece to achieve dynamic blocking. It is worth noting that when the isolating element is dynamically controlled: by providing the isolating element, the annular baffle 29 of different diameters is replaced according to the size of the processing pipeline. Specifically, the annular baffle 29 is assembled on the central baffle ring 9. Due to the matching arrangement of the isolating element and the grinding element, when the grinding roller 15 contacts the inner wall of the processing pipeline, the grinding roller 15 first applies a force to the extrusion plate 20, and the medium temporarily stored in the extrusion chamber 19 is sent into the annular airbag 30 through the extrusion plate 20, and the annular airbag 30 is controlled to expand and contact with the processing pipeline in a sealed manner, thereby completing a stable dynamic control. Dynamic isolation operation is performed to prevent smoke and dust from interfering with the spraying work area. At the same time, under the control of spring No. 1 22, the grinding roller 15 carries a certain pressure to contact the inner wall of the processing pipeline, ensuring the consistency of grinding and avoiding the problem of poor grinding uniformity. This design allows the grinding roller 15 to be dynamically used with the annular airbag 30, providing a stable clamping force for the grinding roller 15 and controlling the annular airbag 30 to maintain a certain amount of expansion. The two cooperate with each other, so that the grinding and spraying process can be carried out safely and stably, which is conducive to construction.

[0027] Embodiment 3: Based on the polishing unit provided in Embodiment 1, this embodiment provides a further technical solution for the polishing unit.

[0028] like Figure 3 , Figure 7 As shown, the regulating arm 6 comprises: The central shaft 10 is concentrically arranged on the central retaining ring 9, and the central shaft 10 rotates through the central plate of the running member, and adjustment areas are opened at both ends of the central shaft 10; The two extension arms 11 are symmetrically slidably engaged in the two adjustment areas. A plurality of positioning holes are arranged side by side on each extension arm 11, and positioning bolts are passed through the ends of the two extension arms 11. The two positioning bolts pass through the positioning holes to restrict the extension arms 11 to the adjustment area. Two telescopic frames 12 are correspondingly arranged at the tails of the two extension arms 11, and a telescopic arm 13 is slidably arranged in each telescopic frame 12, and an electric push rod for controlling the telescopic arm 13 to extend and retract is arranged in each telescopic frame 12; like Figure 6 and Figure 8 As shown, in an embodiment of the present invention, the grinding piece includes: A grinding seat 14 is arranged above one end of the adjusting arm 6, and the top of the grinding seat 14 is open. A grinding roller 15 is rotatably installed in the grinding seat 14, a third gear 16 is fixedly sleeved on one end of the grinding roller 15, and a grinding motor connected to the grinding roller 15 is arranged on the grinding seat 14; A cleaning roller 17 is rotatably disposed in the grinding seat 14, and the cleaning roller 17 is in contact with the top of the grinding roller 15 to complete the cleaning. A fourth gear 18 meshing with the third gear 16 is fixedly sleeved on one end of the cleaning roller 17; It is worth mentioning that: when performing the grinding process: by providing a grinding unit, firstly, 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 piece contacts the inner wall of the processing pipe, and the grinding process of the processing pipe is completed with the rotation of the grinding roller 15. When the grinding roller 15 rotates for grinding, the meshing transmission of the third gear 16 and the fourth gear 18 makes the cleaning roller 17 rotate synchronously. With the help of the rotating cleaning roller 17, the grinding roller 15 can be cleaned to ensure the cleanliness of the grinding roller 15. At the same time, the smoke and dust generated during the grinding process are collected centrally through the suction nozzle 23, and then the smoke and dust are sucked out. Dust impurities enter the circular channel 24, and the smoke impurities are filtered by the circular filter cartridge 25. The smoke is transferred to the outside through the conveying pipe for centralized storage. Since the circular filter cartridge 25 can rotate in the circular channel 24, when the grinding roller 15 rotates, it synchronously drives the cleaning roller 17 and the trigger ring to follow the rotation. The design of the friction convex block 28 is adopted. When the trigger ring rotates, it can intermittently contact the friction ring 26. When the friction convex block 28 and the friction ring 26 are frictionally driven, the circular filter cartridge 25 follows the rotation, and the contact position of the circular filter cartridge 25 and the conveying channel 27 can be changed, so as to avoid the problem that the air volume is affected by the blockage of impurities, ensure the stability of smoke purification, and reduce the maintenance frequency; The extrusion includes: The extrusion chamber 19 is disposed below the grinding piece and has an open top. A certain amount of medium is injected into the extrusion chamber 19, and the medium is specifically one of oil and gas.

The bottoms of the two guide rods 21 slide out of the extrusion chamber 19, and a limiting head is installed at the bottom of the two guide rods 21. A No. 1 spring 22 is correspondingly sleeved on the outside of the two guide rods 21. The two No. 1 springs 22 are provided between the extrusion plate 20 and the extrusion chamber 19 for resetting. like Fig. 9 and Fig.10 As shown, in an embodiment of the present invention, the adsorption component includes: A suction nozzle 23 is provided at one side of the top of the grinding seat 14 for adsorption; The circular channel 24 is arranged on one side of the grinding seat 14 through a bracket, and the bottom of the circular channel 24 is spaced apart from the grinding seat 14, and an end cap is installed on the top of the circular channel 24 through threaded engagement; A circular filter cartridge 25 is rotatably disposed in the circular channel 24, and the circular filter cartridge 25 is rotatably connected to the grinding seat 14, and filter through holes are arranged in a circular array around the circular filter cartridge 25, and a friction ring 26 is fixedly sleeved at the bottom of the circular filter cartridge 25; The adsorbent also includes: The conveying channel 27 is connected to one side of the circular channel 24. The conveying channel 27 is connected to the dust collector through a pipeline, and the dust collector is arranged on one side of the walking member; The trigger ring is fixedly sleeved on one end of the cleaning roller 17, and a friction lug 28 is protruding from one side of the trigger ring. The friction lug 28 and the friction ring 26 are in friction contact to control the rotation of the circular filter cartridge 25; like Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, in the embodiment of the present invention, the driving member includes: The sensing gear ring 31 is fixedly sleeved on the central axis 10 of the regulating arm 6; A driving gear 32 is rotatably disposed on the center plate of the traveling member, and the driving gear 32 is meshed and transmission-connected with the sensing gear ring 31, and a control motor transmission-connected with the driving gear 32 is disposed on the center plate of the traveling member through a bracket; It is worth noting that: when performing circular grinding and spraying: after the grinding roller 15 and the spray pipe 46 move to the predetermined position, the control motor is started, and the driving gear 32 and the sensing gear ring 31 are meshed and driven, so that the central shaft 10 rotates in a circular manner. Since the two ends of the adjustment arm 6 are respectively connected to the grinding unit and the spraying unit, the synchronous linkage grinding unit and the spraying unit perform circular rotation processing, which improves the processing efficiency and optimizes the construction process; The push ring 33 is fixedly sleeved on the central axis 10 of the adjustment arm 6 through a bracket, and an extrusion boss 34 is protrudingly provided on the push ring 33. Both sides of the extrusion boss 34 are provided with inclined surfaces, and the extrusion boss 34 is on the same horizontal line as the grinding roller 15 of the grinding piece and the nozzle 46 of the spray unit. A walking track 35 is provided on the push ring 33 and the extrusion boss 34, and a roller 36 is slidably engaged in the walking track 35; The trigger chamber 37 is arranged on the central plate of the moving part, and the top of the trigger chamber 37 is open. A certain amount of medium is injected into the trigger chamber 37, and the medium is specifically one of oil and gas. A piston member 38 is installed in the trigger chamber 37 in a sliding seal. The piston member 38 consists of a piston plate and a piston rod. The piston plate is slidingly sealed in the trigger chamber 37, and the piston rod is fixedly arranged on the piston plate as a whole. The front end of the piston member 38 is rotatably connected to the roller 36 through a bracket. A second spring 39 is disposed between the piston 38 and the trigger chamber 37, and the piston 38 is controlled to return to its original position by the second spring 39; The drive also includes: A traveling gear 40 is arranged on one of the traveling wheels 5 of the traveling member, and a one-way bearing 41 is installed between the traveling gear 40 and one of the traveling wheels 5 of the traveling member, and the one-way driving control of the traveling gear 40 is completed by the one-way bearing 41; The push chamber 42 is arranged on one of the second arms 4 of the walking member, and the front end of the push chamber 42 is open. A sliding plate 43 is slidably and sealably installed in the push chamber 42, and the push chamber 42 communicates with the trigger chamber 37 through a pipeline; The pushing rack 44 is fixedly disposed at the front end of the sliding plate 43, and the pushing rack 44 can be hidden in the pushing chamber 42, and the pushing rack 44 is meshed and connected with the traveling gear 40; A third spring 45 is disposed between the sliding plate 43 and the pushing chamber 42, and the sliding plate 43 is controlled to return to its original position by the third spring 45; It is worth noting that when the walking part is controlled to move: by providing a driving part and adopting the design of the extrusion boss 34, the central shaft 10 rotates synchronously with the linkage push ring 33 in the circular rotation, and the extrusion boss 34 is on the same horizontal line as the grinding roller 15 and the nozzle 46. Therefore, after the grinding roller 15 and the nozzle 46 complete a processing in the circular direction, the extrusion boss 34 acts synchronously, and the piston 38 is squeezed through the transmission of the roller 36 and the walking track 35, so that the piston 38 extends out in the trigger chamber 37 for suction, and the medium in the push chamber 42 is guided into the trigger chamber 37, so that the push rack 44 is hidden in the push chamber 42, so that under the action, the one-way bearing 41 is in an unlocked state, so that the walking wheel 5 does not rotate, and then the push ring 33 continues to When the following rotation continues, the roller 36 slides from the extrusion boss 34 to the push ring 33, so that the piston 38 moves in the trigger chamber 37 to push, and pushes the medium in the trigger chamber 37 into the push chamber 42, so that the push rack 44 gradually extends. At this time, the one-way bearing 41 is in a locked state, so that the walking wheel 5 follows the rotation, and the walking parts and the grinding unit and the spraying unit are controlled to move forward as a whole. The overall movement control can be completed based on the single circular processing of the grinding unit and the spraying unit, which reduces the control difficulty, and the walking processing can be automatically completed. The walking amount can be adaptively fine-tuned according to the width of the extrusion boss 34, so that the equipment can complete autonomous movement and walking according to the grinding speed, and fully carry out comprehensive grinding processing, which greatly reduces the construction difficulty; In an embodiment of the present invention, the spraying unit includes: The nozzle 46 is disposed above one end of the adjusting arm 6, and a feed pipe is disposed on one side of the nozzle 46, the feed pipe is communicated with the spraying agent through a pipeline, and the nozzle 46 is specifically detachably fixedly connected to the top of the telescopic arm 13; A plurality of nozzles 47 are arranged side by side and connected to the nozzle pipe 46 at intervals; It is worth mentioning that when spraying: by providing a spraying unit, the extension distance of the extension arm 11 is also adjusted freely according to the processing environment first, and then the electric push rod is started to control the extension length of the telescopic arm 13, so that the nozzle 46 and the processing pipeline maintain a certain distance, and then the spray material is fed into the nozzle 46, and the paint is evenly sprayed onto the inner wall of the processing pipeline through multiple nozzles 47, which can organically combine grinding and spraying, improve construction efficiency, and do not need to repeatedly replace different equipment for construction, greatly reducing the difficulty of construction.
