Description

Technical Field

[0001] This invention belongs to the technical field of concrete cutting equipment, specifically a device for cutting large-area concrete cracks in garages and its control method. Background Technology

[0002] Concrete cutting equipment is construction machinery used for cutting concrete. Based on different power sources, it is mainly divided into the following types: diesel cutting machine, gasoline cutting machine, hydraulic cutting machine, and electric cutting machine. These devices drive the saw blade or cutting disc to rotate through different power sources, so as to achieve precise cutting of concrete. They are widely used in construction, road construction and other fields.

[0003] In existing technologies, most concrete cutting equipment is equipped with nozzles to spray and cool the cutting blade during operation. During the cutting process, the blade generates a large amount of dust and impurities. After being moistened by the nozzle spray, the dust and impurities are rolled up and adhere to the top of the inner wall of the mounting cover due to the rotation of the blade. If these damp dust particles are not cleaned in time, they will not only drip and adhere to the cutting blade, affecting its sharpness, but also accumulate until they come into contact with the cutting blade, causing wear. However, existing cutting equipment lacks the function of automatically cleaning these dust and impurities, and can only be cleaned manually by the workers. Since the dust is on the inner wall of the mounting cover and close to the cutting blade, it not only increases the workload of the workers and reduces work efficiency, but also poses a very high safety hazard.

[0004] Therefore, the present invention provides a device for cutting large-area concrete cracks in garages and a method for controlling the same. Summary of the Invention

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1-13As shown in the embodiment of the present invention, a large-area garage concrete crack cutting device includes a body 1. A mounting cover 2 is fixedly connected to one side of the body 1. A cutting blade 3 is rotatably connected to the inner cavity of the mounting cover 2. An arc-shaped through groove 23 and two arc-shaped limiting grooves 24 are provided on the outer wall of the mounting cover 2. An arc-shaped guard plate 9 is provided on the outer side of the mounting cover 2. The arc-shaped guard plate 9 is slidably connected to the arc-shaped limiting grooves 24. A water spray pipe 10 is rotatably connected to the arc-shaped guard plate 9. The water spray pipe 10 is slidably connected to the arc-shaped through groove 23. The inner end of the water spray pipe 10 extends into the inner cavity of the mounting cover 2 and is equipped with two sets of nozzles 12. The two sets of nozzles 12 are evenly distributed on both sides of the cutting blade 3. The outer end of the water spray pipe 10 extends to the outer side of the mounting cover 2 and is connected to the water inlet pipe 11. A baffle 26 is vertically installed inside the mounting cover 2. An annular connecting frame 25 is fixedly connected to one side of the baffle 26. The annular connecting frame 25 is rotatably connected to the water spray pipe 10. The baffle 26 is adapted to the cutting blade 3. Both bottom ends of the baffle 26 are fixedly connected to... The limiting ring 27 is rotatably connected to the inner wall of the mounting cover 2. During operation, the operator pushes the machine body 1, and the cutting blade 3 cuts the concrete ground. The water inlet pipe 11 of the external water supply tank supplies water to the spray pipe 10. The water is sprayed from the nozzle 12 on the spray pipe 10 to spray and cool the rotating cutting blade 3. A baffle 26 is vertically installed at the center of the inner cavity of the mounting cover 2. The dust that is wetted by the spray nozzle 12 is rolled up by the rotation of the cutting blade 3 and blocked by the baffle 26, preventing the wet dust from being cut. When piece 3 enters the concrete, it causes unevenness on the cut surface, affecting the cutting quality. After the cutting operation is completed, when the workers clean the damp dust adhering to the inner wall of the mounting cover 2, they hold the outer end of the water spray pipe 10 and rotate it. The nozzle 12 rotates accordingly and sprays water onto the inner wall of the mounting cover 2. Then, the sliding arc-shaped guard plate 9 drives the water spray pipe 10 to make a quarter-circular motion, so that the nozzle 12 cleans one side of the inner cavity of the mounting cover 2 with damp dust, reducing the workload of the cleaning operation and improving work efficiency.

[0039] An arc-shaped seat 4 is fixedly connected to the outer wall of the mounting cover 2. A slider 5 is slidably connected to the inner cavity of the arc-shaped seat 4. A spring 7 is fixedly connected between the slider 5 and the inner cavity wall of the arc-shaped seat 4. A connecting block 6 is fixedly connected to the slider 5. The end of the connecting block 6 away from the slider 5 extends to the outer side of the arc-shaped seat 4 and is fixedly connected to the arc-shaped guard plate 9. A lever 8 is fixedly connected to the connecting block 6. During operation, by setting the spring 7 inside the arc-shaped seat 4, the water spray pipe 10 is positioned above the cutting blade 3 to spray and cool the cutting blade 3. When cleaning is required, the sliding lever 8 drives the arc-shaped guard plate 9 to slide, and the water spray pipe 10 drives the nozzle 12 to slide accordingly to achieve the spray cleaning operation. At this time, the spring 7 is stretched by the slider 5. After the cleaning operation is completed, the operator releases the lever 8. Through the pulling force of the spring 7, the slider 5 drives the arc-shaped guard plate 9 and the water spray pipe 10 to return to their original positions.

[0040] The outer end of the water spray pipe 10 is provided with an annular groove 21, and a spiral groove 22 is provided on the inner wall of the annular groove 21. A bracket 13 is fixedly connected to the arc-shaped guard plate 9. The bracket 13 is sleeved on the water spray pipe 10. A torsion spring 14 is fixedly connected between the water spray pipe 10 and the bracket 13. An installation sleeve 15 is fixedly connected to the bracket 13. An angle adjustment component is provided inside the installation sleeve 15. The angle adjustment component is compatible with both the annular groove 21 and the spiral groove 22. During operation, the operator drives the water spray pipe 10 to rotate through the angle adjustment component. After the nozzle 12 on the water spray pipe 10 rotates, it sprays water onto the top of the inner wall of the installation cover 2. When the operator slides the arc-shaped guard plate 9, he only needs to hold the lever 8 with one hand and no longer needs to fix the water spray pipe 10.

[0041] The angle adjustment component includes a threaded ring 17 and an adjusting ring 18. The threaded ring 17 is internally threaded onto the mounting sleeve 15. The adjusting ring 18 is rotatably connected to one end of the threaded ring 17 near the bracket 13. The adjusting ring 18 is fitted into the annular groove 21. A straight groove 16 is formed on the inner wall of the mounting sleeve 15 near the bracket 13, corresponding to the spiral groove 22. A limiting protrusion 19 and a limiting protrusion 20 are fixedly connected to the outer wall of the adjusting ring 18. The first limiting protrusion 19 is slidably connected to both the spiral groove 22 and the straight groove 16, and the second limiting protrusion 20 is slidably connected to the straight groove 16. During operation, by rotating the threaded ring 17 into the mounting sleeve 15, the adjusting ring 18 slides accordingly. The sliding engagement of the first limiting protrusion 19 and the second limiting protrusion 20 with the straight groove 16 ensures that the adjusting ring 18 only slides axially and does not rotate with the threaded ring 17. When the first limiting protrusion 19 slides from the straight groove 16 into the spiral groove 22, the second limiting protrusion 20 remains in the straight groove... The water spray pipe 10 rotates as the nozzle 12 of the water spray pipe 10 sprays water onto the inner wall of the mounting cover 2. At this time, the torsion spring 14 is in a stored state and stops rotating the threaded ring 17. When the operator slides the arc-shaped guard plate 9 to make the water spray pipe 10 slide to the bottom of one side of the mounting cover 2, the operator continues to rotate the threaded ring 17, and the water spray pipe 10 rotates again until the limit protrusion 20 slides to the connection between the straight groove 16 and the spiral groove 22 and is stuck by the spiral groove 22. The nozzle 12 on the water spray pipe 10 sprays water onto the top of the baffle 26, and the water flows down the baffle 26 to clean the baffle 26. After cleaning, the operator reverses the threaded ring 17 to make the adjusting ring 18 leave the water spray pipe 10. The water spray pipe 10 is reset under the action of the torsion spring 14. The operator slowly rotates the cutting blade 3 so that the nozzle 12 sprays water onto the cutting blade 3 again to prevent dust and impurities attached to the inner wall of the mounting cover 2 from dripping onto the cutting blade 3 during the cleaning process.

[0042] A marker 38 is fixedly connected to the bracket 13. The marker 38 has a pointed protrusion. The top of the baffle 26 has an opening groove 37, and a scraper 28 is installed in the opening groove 37. The scraper 28 fits against the inner top of the mounting cover 2. During operation, by setting the marker 38 on the bracket 13, the end of the threaded ring 17 is rotated to the position of the pointed protrusion. The nozzle 12 on the water spray pipe 10 is facing the top of the inner wall of the mounting cover 2. The scraper 28 is installed in the opening groove 37 at the top of the baffle 26. When the operator slides the arc-shaped guard plate 9 to drive the water spray pipe 10 to spray the top of the inner wall of the mounting cover 2, the baffle 26 drives the scraper 28 to rotate, so that the scraper 28 further cleans the top of the inner wall of the mounting cover 2 after spraying, thereby improving the cleaning effect.

[0043] The bottom of the opening slot 37 is symmetrically provided with T-shaped slots 39. A T-shaped support rod 30 is slidably connected inside the T-shaped slot 39. One end of the T-shaped support rod 30 extends to the outside of the T-shaped slot 39 and is fixedly connected to the scraper 28. A spring 29 is fixedly connected between the T-shaped support rod 30 and the inner wall of the T-shaped slot 39. Arc-shaped guide slots 34 and 35 are provided on both sides of the inner wall of the mounting cover 2. Guide members are provided on both sides of the scraper 28. The guide members are adapted to the arc-shaped guide slots 34 and 35. When the operator slides the arc-shaped guard plate 9 to drive the baffle 26 to rotate, the guide members on the scraper 28 slide along the arc-shaped guide slot 34 to further clean the top of the inner wall of the mounting cover 2 until the water spray pipe 10 rotates to the bottom of one side of the mounting cover 2. At this time, the guide members slide from the arc-shaped guide slot 34. 4. Slide into the arc-shaped guide groove 35 and slide along the arc-shaped guide groove 35 during the process of the water spray pipe 10 driving the baffle 26 to reset. During this process, the scraper 28 slides into the opening groove 37, causing the T-shaped support rod 30 to compress the spring 29, effectively preventing the scraper 28 from contacting the top of the inner wall of the mounting cover 2 again, thus achieving one-way cleaning. When the water spray pipe 10 is located at the bottom of one side of the mounting cover 2, the operator manipulates the nozzle 12 on the water spray pipe 10 to rotate and spray the scraper 28 and the baffle 26 for cleaning. After the operator releases the lever 8 and the water spray pipe 10 resets, the guide slides back into the arc-shaped guide groove 34. Under the elastic force of the spring 29, the T-shaped support rod 30 drives the scraper 28 to slide out of the opening groove 37 again and contact the top of the inner wall of the mounting cover 2, thus achieving the function of shielding in conjunction with the baffle 26.

[0044] The bottom end of the arc-shaped guide groove 34 is connected to the bottom end of the arc-shaped guide groove 35. The bottom end of the arc-shaped guide groove 34 is an inclined groove, and a pad 36 is fixedly connected inside the inclined groove. The side of the pad 36 away from the arc-shaped guide groove 35 is set as an inclined surface, and the top end of the arc-shaped guide groove 35 is set as an inclined surface. By setting an inclined groove at the bottom end of the arc-shaped guide groove 34 and setting a pad 36 with an inclined surface on one side inside the inclined groove, the guide component does not return to the arc-shaped guide groove 34 again during the reset process of the water spray pipe 10 after sliding from the arc-shaped guide groove 34 to the arc-shaped guide groove 35.

[0045] The guide component includes a fixed sleeve 31, a spring 32, and a guide block 33. Fixed sleeves 31 are embedded in both sides of the scraper 28. A guide block 33 is slidably connected inside the fixed sleeve 31. A spring 32 is fixedly connected between the guide block 33 and the inner wall of the fixed sleeve 31. The end of the guide block 33 away from the spring 32 extends to the outer side of the fixed sleeve 31 and is slidably connected to the first arc-shaped guide groove 34 and the second arc-shaped guide groove 35. When the guide block 33 slides onto the pad 36, the guide block 33 retracts into the fixed sleeve 31 and compresses the spring. Spring 32, until guide block 33 slides away from pad block 36, under the action of spring 32, guide block 33 contacts arc-shaped guide groove 2 35. When guide block 33 slides to the top inclined surface of arc-shaped guide groove 2 35, guide block 33 retracts and compresses spring 32 again until guide block 33 slides away from arc-shaped guide groove 2 35. Scraper 28 slides out of opening groove 37 under the elastic force of spring 2 29. At this time, guide block 33 slides back into arc-shaped guide groove 1 34 to prepare for the next cleaning work of scraper 28.

[0046] The top of the opening groove 37 near the water spray pipe 10 is chamfered; when the guide block 33 slides into the arc-shaped guide groove 35, the scraper 28 slides into the opening groove 37. Through the chamfer on the opening groove 37, the nozzle 12 on the water spray pipe 10 cleans the scraper 28, and the water sprayed on the scraper 28 slides down the baffle 26 along the chamfer.

[0047] A control method for a large-area garage concrete crack cutting device, applicable to the aforementioned large-area garage concrete crack cutting device, the control method comprising the following steps:

[0048] S1: Push the machine body 1 to make the cutting blade 3 cut the concrete ground, connect the water inlet pipe 11 to the external water supply equipment to send water into the spray pipe 10, and spray water from the nozzle 12 on the spray pipe 10 to spray and cool the rotating cutting blade 3.

[0049] S2: After the cutting operation is completed, the worker rotates the threaded ring 17 to the pointed protrusion of the marker 38, so that the nozzle 12 on the water spray pipe 10 rotates and faces the top of the inner wall of the mounting cover 2. Then, the lever 8 is slid to make the arc-shaped guard plate 9 drive the water spray pipe 10 to make a quarter-circular motion, thus completing the cleaning of the top of the inner wall of the mounting cover 2.

[0050] S3: When the water spray pipe 10 is rotated to the bottom of one side of the mounting cover 2, rotate the threaded ring 17 again so that the nozzle 12 on the water spray pipe 10 rotates again to spray water onto the baffle 26 to clean the baffle 26. After cleaning, release the lever 8 and reset the threaded ring 17 so that the nozzle 12 is aligned with the cutting disc 3 again.

[0051] Working principle:

[0052] Workers push the machine body 1, and the cutting blade 3 cuts the concrete floor. Water is supplied from the water inlet pipe 11 of the external water tank into the spray pipe 10. Water is sprayed from the nozzles 12 on the spray pipe 10 to cool the rotating cutting blade 3. A baffle 26 is vertically installed at the center of the inner cavity of the mounting cover 2. Dust sprayed and moistened by the nozzles 12 is rolled up by the rotating cutting blade 3 and blocked by the baffle 26, preventing damp dust from entering the concrete along with the cutting blade 3, causing uneven cut surfaces and affecting cutting quality. After the cutting operation is completed, when cleaning the damp dust adhering to the inner wall of the mounting cover 2, workers hold the outer end of the spray pipe 10 and rotate it, causing the nozzles 12 to rotate and spray water onto the inner wall of the mounting cover 2. Then, by sliding the arc-shaped guard plate 9, the water spray pipe 10 is driven to make a quarter-circle motion, so that the nozzle 12 cleans one side of the inner cavity of the mounting cover 2 which is covered with damp dust, reducing the workload of the cleaning operation and improving the work efficiency; by setting a spring 7 in the arc-shaped seat 4, when cutting, the water spray pipe 10 is above the cutting blade 3 to spray and cool the cutting blade 3. When cleaning is required, the arc-shaped guard plate 9 is driven to slide by the sliding lever 8, and the water spray pipe 10 drives the nozzle 12 to slide to realize the spray cleaning operation. At this time, the spring 7 is stretched by the slider 5. After the cleaning operation is completed, the operator releases the lever 8, and through the pulling force of the spring 7, the slider 5 drives the arc-shaped guard plate 9 and the water spray pipe 10 to return to their original positions.Rotate the threaded ring 17 into the mounting sleeve 15. The adjusting ring 18 slides accordingly. The first limiting protrusion 19 and the second limiting protrusion 20 slide in the straight groove 16, so that the adjusting ring 18 only slides axially and does not rotate with the threaded ring 17. When the first limiting protrusion 19 slides from the straight groove 16 into the spiral groove 22, the water spray pipe 10 rotates because the second limiting protrusion 20 is still sliding in the straight groove 16, until the nozzle 12 of the water spray pipe 10 sprays water onto the inner wall of the mounting cover 2. At this time, the torsion spring 14 is in a charged state and stops rotating the threaded ring 17. When the operator slides the arc-shaped guard plate 9 to make the water spray pipe 10 slide to the bottom of one side of the mounting cover 2, the operator continues to rotate the threaded ring 17, and the water spray pipe 10 rotates again until the second limiting protrusion 20... The blade 10 slides to the connection between the straight groove 16 and the spiral groove 22 and is stuck by the spiral groove 22. The nozzle 12 on the water spray pipe 10 sprays water towards the top of the baffle 26, and the water flows down the baffle 26 to clean it. After cleaning, the operator reverses the threaded ring 17 to make the adjusting ring 18 leave the water spray pipe 10. The water spray pipe 10 is reset under the action of the torsion spring 14. The operator slowly rotates the cutting blade 3 so that the nozzle 12 sprays water onto the cutting blade 3 again, avoiding dust and impurities attached to the inner wall of the mounting cover 2 from dripping onto the cutting blade 3 during the cleaning process. By setting a marker 38 on the bracket 13, with a pointed protrusion on the marker 38, when the end of the threaded ring 17 is rotated to the position of the pointed protrusion, the nozzle 12 on the water spray pipe 10 sprays water. The head 12 faces the top of the inner wall of the mounting cover 2. A scraper 28 is installed in the opening groove 37 at the top of the baffle 26. When the operator slides the arc-shaped guard plate 9 to drive the water spray pipe 10 to spray the top of the inner wall of the mounting cover 2, the baffle 26 drives the scraper 28 to rotate, so that the scraper 28 further cleans the top of the inner wall of the mounting cover 2 after spraying, improving the cleaning effect. When the operator slides the arc-shaped guard plate 9 to drive the baffle 26 to rotate, the guide on the scraper 28 slides along the arc-shaped guide groove 34 to further clean the top of the inner wall of the mounting cover 2 until the water spray pipe 10 rotates to the bottom of one side of the mounting cover 2. At this time, the guide slides from the arc-shaped guide groove 34 to the arc-shaped guide groove 35, and the water spray pipe 10 drives the baffle 26 to rotate. During the process of positioning, the scraper 28 slides into the arc-shaped guide groove 35. During this process, the scraper 28 slides into the opening groove 37, causing the T-shaped support rod 30 to compress the spring 29, effectively preventing the scraper 28 from contacting the top of the inner wall of the mounting cover 2 again, thus achieving one-way cleaning. When the water spray pipe 10 is located at the bottom of one side of the mounting cover 2, the operator manipulates the nozzle 12 on the water spray pipe 10 to rotate, spraying and cleaning the scraper 28 and the baffle 26. After the operator releases the lever 8 and the water spray pipe 10 is reset, the guide slides back into the arc-shaped guide groove 34. Under the elastic force of the spring 29, the T-shaped support rod 30 drives the scraper 28 to slide out of the opening groove 37 again and contact the top of the inner wall of the mounting cover 2, thus achieving the function of shielding in conjunction with the baffle 26.When the guide block 33 slides onto the pad 36, the guide block 33 retracts into the fixed sleeve 31 and compresses the spring 32 until the guide block 33 slides away from the pad 36. Under the action of the spring 32, the guide block 33 contacts the arc-shaped guide groove 35. When the guide block 33 slides to the top inclined surface of the arc-shaped guide groove 35, the guide block 33 retracts again and compresses the spring 32 until the guide block 33 slides away from the arc-shaped guide groove 35. The scraper 28 is under the influence of the spring 29. The guide block 33 slides out of the opening groove 37 under the elastic force, and then slides back into the arc-shaped guide groove 34 to prepare for the next cleaning operation of the scraper 28. When the guide block 33 slides into the arc-shaped guide groove 35, the scraper 28 slides into the opening groove 37. Through the chamfer set on the opening groove 37, in conjunction with the nozzle 12 on the water spray pipe 10, the scraper 28 is cleaned, and the water sprayed on the scraper 28 slides off the baffle 26 along the chamfer.
