Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and in particular relates to a U-shaped groove cleaning device. Background Technology

[0002] In industrial production processes such as electrolysis, U-shaped tanks are crucial production equipment, and their interiors are prone to accumulating various waste residues and impurities, requiring regular cleaning. Current methods for cleaning electrolytic U-shaped tanks primarily rely on extensive manual labor after equipment shutdown. However, manual cleaning is not only extremely inefficient and fails to meet the demands of continuous industrial production, but also presents numerous safety hazards for workers operating in complex environments, such as slipping, bumping, and exposure to hazardous substances. Furthermore, cleaning during equipment shutdowns results in significant production losses. Therefore, there is an urgent need for a more efficient and safer U-shaped tank cleaning device that can replace manual labor. Summary of the Invention

The cleaning robot is mounted on the track and moves along it. The cleaning robot includes a moving mechanism, an adaptive mechanism, and a cleaning mechanism. The moving mechanism is mounted on the track, and the adaptive mechanism is connected to it. The cleaning mechanism is connected to the adaptive mechanism. The moving mechanism drives the adaptive mechanism and the cleaning robot to move along the track. When the wall of the U-shaped groove deforms, the adaptive mechanism adaptively adjusts the lateral position of the cleaning robot to adapt to the U-shaped groove. The cleaning mechanism includes a fixed frame, a drive cylinder, and a scraping structure. The drive cylinder is mounted on the fixed frame, and the fixed frame is connected to the scraping structure. The drive cylinder drives the scraping structure to switch between an avoidance position and a cleaning position. In the avoidance position, the scraping structure is horizontally positioned above the U-shaped groove. In the cleaning position, the scraping structure is vertically positioned in the U-shaped groove and contacts the groove wall. When the moving mechanism moves to the position of the connecting rod at the top of the U-shaped groove, the scraping structure flips to the avoidance position. When the scraping structure leaves the position of the connecting rod at the top of the U-shaped groove, the scraping structure flips to the cleaning position to clean the groove wall.

The nitrogen spring mounting seat has two nitrogen springs. The two nitrogen springs are connected to the two movable connecting plates respectively. The two nitrogen springs apply a thrust away from each other to the two movable connecting plates to keep the fixed frame balanced.

[0019] To make the objectives, features, and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described below are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, the same or similar reference numerals may be used in the drawings to refer to the same or similar elements in different embodiments, and descriptions of the same or similar elements in different embodiments, as well as descriptions of prior art elements, features, effects, etc., may be omitted.

[0020] Reference Figures 1-9 This invention provides a U-shaped groove cleaning device.

[0021] like Figure 1As shown, the U-shaped channel 100 is set on the foundation 102. A beam and column 103 are set on one side of the U-shaped channel 100, and a wall 104 is set at a certain distance on the other side. Since the U-shaped channel 100 is very long, the top of the U-shaped channel 100 will deform during long-term use. Therefore, connecting rods 101 are set at a certain distance on the top of the U-shaped channel 100 to connect the two side walls of the U-shaped channel 100 to reduce deformation.

[0022] Specifically, the U-shaped trough cleaning device includes a track 2 and a cleaning robot. The track 2 is positioned above one side of the U-shaped trough 100 and parallel to it. The cleaning robot is mounted on the track 2 and moves along it. The cleaning robot includes a moving mechanism 3, an adaptive mechanism 4, and a cleaning mechanism 5. The moving mechanism 3 is mounted on the track 2, and the adaptive mechanism 4 is connected to the moving mechanism 3. The cleaning mechanism 5 is connected to the adaptive mechanism 4. The moving mechanism 3 drives the adaptive mechanism 4 and the cleaning mechanism 5 to move along the track 2. When the wall of the U-shaped trough 100 deforms, the adaptive mechanism 4 adaptively adjusts the lateral position of the cleaning mechanism 5 to adapt to the U-shaped trough 100. The cleaning mechanism 5 includes a fixed frame 51. The drive cylinder 52 and the scraping structure 53 are connected. The drive cylinder 52 is mounted on the fixed frame 51, and the fixed frame 51 is connected to the scraping structure 53. The drive cylinder 52 drives the scraping structure 53 to switch between a clearance position and a cleaning position. In the clearance position, the scraping structure 53 is horizontally positioned above the U-shaped groove 100. In the cleaning position, the scraping structure 53 is vertically positioned in the U-shaped groove 100 and contacts the groove wall of the U-shaped groove 100. When the moving mechanism 3 moves to the position of the connecting rod 101 at the top of the U-shaped groove 100, the scraping structure 53 flips to the clearance position. When the scraping structure 53 leaves the position of the connecting rod 101 at the top of the U-shaped groove 100, the scraping structure 53 flips to the cleaning position to clean the groove wall.

[0023] Specifically, the track 2 is fixed to the side of the beam-column 103 near the U-shaped groove 100.

[0024] In some embodiments, the moving mechanism 3 includes a mounting base plate 31, a drive wheel assembly 32, a driven wheel assembly 33, and a drive structure 34; the drive wheel assembly 32 includes a drive wheel 321, a drive shaft 322, and a drive wheel mounting plate 323; the drive wheel 321 is fixedly mounted on the drive shaft 322, and a drive wheel bearing 324 is provided in the drive wheel mounting plate 323; two sets of drive wheel mounting plates 323 are respectively fixed to both sides of the bottom of the mounting base plate 31; the two ends of the drive shaft 322 with the drive wheel 321 mounted are respectively disposed in the drive wheel bearings 324 of the two sets of drive wheel mounting plates 323; the driven wheel assembly 33 includes a driven wheel 331, a driven shaft 332, and a driven wheel. Mounting plate 333; driven wheel 331 is fixedly mounted on driven shaft 332, driven wheel bearing 334 is provided in driven wheel mounting plate 333, driven wheel mounting plate 333 is in two sets and fixed on both sides of the bottom of mounting base plate 31; the two ends of driven shaft 332 with driven wheel 331 installed are respectively set in driven wheel bearing 334 of two sets of driven wheel mounting plates 333; driving wheel 321 and driving wheel 331 are both set on track 2, driving structure 34 connects to driving shaft 322 and drives driving shaft 322 to rotate, driving driving wheel 321 to rotate and thus driving moving mechanism 3 to move along track 2, and driving driven wheel 331 to rotate when moving mechanism 3 moves.

[0025] In some embodiments, the drive structure 34 includes a motor 341, a reducer 342, a first synchronous pulley 343, a second synchronous pulley 344, and a synchronous belt 345. The motor 341 and the reducer 342 are connected and fixed to the mounting base 31 by a motor mounting seat 346. The rotating shaft of the reducer 342 is connected to the first synchronous pulley 343, the second synchronous pulley 344 is connected to the drive shaft 322, and the synchronous belt 345 connects the first synchronous pulley 343 and the second synchronous pulley 344. The motor 341 drives the first synchronous pulley 343 to rotate, and drives the drive shaft 322 to rotate through the synchronous belt 345 and the second synchronous pulley 344.

[0026] In some embodiments, the moving mechanism 3 further includes a retaining structure 35, which is a plurality of sets. The plurality of sets of retaining structures 35 are respectively disposed on both sides of the bottom of the mounting base plate 31. The retaining structure 35 includes a retainer mounting seat 351, a retainer 352, and a retaining shaft 353. The retainer mounting seat 351 is fixed to one side of the bottom of the mounting base plate 31, and the retainer 352 is connected to the retainer mounting seat 351. A retainer bearing 354 is disposed in the retainer 352, and the retaining shaft 353 is disposed in the retainer bearing 354. When the driving wheel 321 and the driven wheel 331 are disposed on the track 2, the retainer 352 is located on one side of the track 2, and the retaining shaft 353 is located below the track 2 and in contact with the track 2. When the driving wheel 321 moves along the track 2, the retaining shaft 353 rotates. The retaining structure 35 prevents the moving mechanism 3 from deviating from the track 2.

[0027] In some embodiments, the retainer mounting base 351 is connected to the retainer 352 by a screw 355, and a locking nut 356 is provided on the screw 355. The height of the retainer 352 is adjusted by adjusting the screw 355 and the locking nut 356.

[0028] Specifically, a control box 6 is also provided on the mounting base plate 31, and a controller (not shown) is provided in the control box 6. The controller controls the operation of the moving mechanism 3 and the cleaning mechanism 5.

[0029] Specifically, a first protective cover 8 is provided above the mounting base plate 31. The first protective cover 8 covers the top of the moving mechanism 3 and the control box 6. A cooling fan 81 is provided on the top of the first protective cover 8.

[0030] Specifically, an air compressor 7 is also installed on the mounting base plate 31, which provides compressed air to the device.

[0031] In some embodiments, the adaptive mechanism 4 includes a crossbar 41. The bottom of one end of the crossbar 41 is fixed to the moving mechanism 3 via a crossbar mounting plate 42. Two slide rail mounting plates 43 are vertically parallel to each other on the front side of the other end of the crossbar 41. Each slide rail mounting plate 43 is laterally provided with a linear slide rail 44. Each of the two linear slide rails 44 is provided with a movable connecting plate 45 that can move laterally along the linear slide rail 44. The two movable connecting plates 45 are respectively fixedly connected to the two sides of the fixed frame 51. A nitrogen spring mounting seat 46 is provided between the two slide rail mounting plates 43. Two nitrogen springs 47 are provided on the seat 46. The two nitrogen springs 47 are respectively connected to two movable connecting plates 45. The two nitrogen springs 47 apply a pushing force away from each other to the two movable connecting plates 45, so that the fixed frame 51 is kept in balance. When an external pushing force is applied to one side of the fixed frame 51, the fixed frame 51 and the movable connecting plates 45 move a certain distance along the linear slide rail 44 in the direction of the external pushing force, and stop moving when the pushing force generated by the two nitrogen springs 47 is balanced with the external pushing force. When the external pushing force is removed, the two nitrogen springs 47 restore the original state.

[0032] Specifically, when the scraper structure 53 is in the cleaning position, if the U-shaped groove 100 undergoes slight deformation, and the groove wall protrudes or indents to one side, the groove wall applies an external thrust to one side of the scraper structure 53, that is, applies an external thrust to one side of the fixed frame 51. At this time, the fixed frame 51 drives the scraper structure 53 and the movable connecting plate 45 to move a certain distance along the linear slide rail 44 in the direction of the external thrust, so that the thrust generated by the two nitrogen springs 47 is balanced with the external thrust, and then stops moving, automatically adapting to the lateral position change caused by the deformation of the U-shaped groove 100; when it moves to the non-deformed position of the U-shaped groove 100, the external thrust applied by the groove wall is removed, and the fixed frame 51 drives the scraper structure 53 and the movable connecting plate 45 to return to their original state under the action of the two nitrogen springs 47.

[0033] Specifically, one end of the crossbar 41 is fixed to the top of the mounting base plate 31 of the moving mechanism 3 via the crossbar mounting plate 42.

[0034] Specifically, the adaptive mechanism 4 and the fixed frame 51 are covered with a second protective cover 9.

[0035] In some embodiments, the fixed frame 51 is generally inverted L-shape. The bottom of the fixed frame 51 is movably connected to the movable frame 512 via a hinge 511. The front end of the movable frame 512 is fixedly connected to the scraper structure 53. The fixed end of the drive cylinder 52 is pin-connected to the first movable mounting seat 521 located on the top of the fixed frame 51. The telescopic end of the drive cylinder 52 is pin-connected to the second movable mounting seat 522 located on the front end of the movable frame 512. The telescopic end of the drive cylinder 52 retracts or extends, causing the scraper structure 53 to switch between an avoidance position and a cleaning position.

[0036] Specifically, the front end of the active frame 512 is the end furthest from the fixed frame 51.

[0037] In some embodiments, the slag scraping structure 53 includes a slag scraping frame 531, which is rectangular; a first roller brush 532 is rotatably connected to both sides of the slag scraping frame 531, and a second roller brush 533 is rotatably connected to the front end of the slag scraping frame 531; when the slag scraping structure 53 is in the cleaning position, the first roller brush 532 contacts the two side walls of the U-shaped groove 100; and the second roller brush 533 contacts the bottom surface of the U-shaped groove 100.

[0038] Specifically, the front end of the scraper frame 531 is the end furthest from the movable frame 512.

[0039] In some embodiments, both ends of the first roller brush 532 are mounted to the slag scraping frame 531 via a first mounting member 534, a first ceramic bearing 535 is provided in the first mounting member 534, and the end of the first roller brush 532 is disposed in the first ceramic bearing 535; both ends of the second roller brush 533 are mounted to the slag scraping frame 531 via a second mounting member 536, a second ceramic bearing 537 is provided in the second mounting member 536, and the end of the second roller brush 533 is disposed in the second ceramic bearing 537.

[0040] In some embodiments, a first sensor (not shown) and a second sensor (not shown) for detecting the connecting rod 101 are also included; the first sensor and the second sensor are respectively fixedly mounted on a first sensor bracket (not shown) and a second sensor bracket (not shown), the first sensor bracket being disposed below the crossbar 41; the second sensor bracket is fixed to the front end of the fixed frame 51, and when the scraper structure 53 is in the avoidance position, the second sensor is located in front of the scraper structure 53.

[0041] Specifically, both the first and second sensors are connected to the controller.

[0042] The working process of the U-shaped groove cleaning device according to an embodiment of the present invention is as follows: The moving mechanism 3 moves along the track 2. When the first sensor detects the connecting rod 101 in the middle of the U-shaped groove 100, it triggers a signal and transmits it to the controller. After receiving the signal, the controller controls the moving mechanism 3 to stop running. Subsequently, it controls the drive cylinder 52 to retract and flips the scraper structure 53 to the avoidance position. When the scraper structure 53 flips to the avoidance position, the controller controls the moving mechanism 3 to continue moving forward a fixed distance or stops when the second sensor detects the connecting rod 101 in the middle of the U-shaped groove 100. Then, the controller controls the drive cylinder 52 to extend and flip the scraper structure 53 to the initial cleaning position. The moving mechanism 3 drives the scraper structure 53 to move back and forth (the moving distance is determined according to parameters such as the distance between the connecting rods 101) to clean the groove wall and repeat the above action process when encountering the connecting rod 101, so as to realize the continuous cleaning of waste residue in the U-shaped groove 100.

[0043] The cleaning mechanism 5 is connected to the adaptive mechanism 4. When the U-shaped groove 100 undergoes slight deformation, the adaptive mechanism 4 automatically adjusts the left and right positions of the cleaning mechanism 5 to ensure that the scraping structure 53 always maintains a good fit with the inner wall of the U-shaped groove 100, thus ensuring the cleaning effect.

[0044] In summary, the U-shaped channel cleaning device of this invention achieves automated cleaning of the U-shaped channel 100 without requiring shutdown and waiting for manual cleaning. Cleaning can be performed during equipment operation breaks or continuous operation, significantly improving the cleaning efficiency of the U-shaped channel 100, reducing equipment downtime, and enhancing the continuity and efficiency of industrial production. The adaptive mechanism 4 automatically adapts to slight deformations of the U-shaped channel 100, ensuring efficient cleaning under different working conditions and improving the versatility and reliability of the equipment. It replaces traditional manual labor, avoiding workers operating in confined and dangerous environments, reducing labor costs, eliminating safety hazards during manual cleaning, and protecting the lives and health of workers.
