Detailed implementation manners

[0066] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. 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 scope of protection of the present invention.

[0067] As Figures 1 to 6 As shown, in at least one embodiment, a cutting device 2 for concrete is provided, including: a housing 1, a cutting device 2 and a cooling device 3; the cutting device 2 is arranged on the housing 1, and the cutting device 2 is suitable for cutting concrete; the cooling device 3 is arranged on the housing 1, the cooling device 3 is suitable for cooling the cutting device 2, and the cooling device 3 is suitable for adjusting the water outlet position of the cooling water according to the cutting depth of the cutting device 2; it is realized that the cooling effect of the cooling device 3 can be ensured when cutting concrete at different depths, and the influence of the too high temperature of the cutting device 2 on the cutting effect and service life is avoided.

[0068] The cooling device 3 includes: a shielding piece 31 and a cooling mechanism; the shielding piece 31 is arranged on the outer wall of the housing 1; the cooling mechanism is arranged in the housing 1, and the cooling mechanism is connected to the shielding piece 31; the shielding piece 31 covers the cutting device 2, and the cutting device 2 extends out from below the bottom surface of the shielding piece 31; the cooling mechanism is suitable for cooling the cutting device 2; a part of the cutting disc 22 is located in the groove 311 of the shielding piece 31, and a part of the cutting disc 22 extends out from the bottom surface of the shielding piece 31, so as to facilitate cutting concrete. During the cutting process, the cooling mechanism sprays cooling water on the cutting disc 22, avoiding the influence of the heat generated by the friction when the cutting disc 22 cuts concrete on the cutting efficiency and effect, and avoiding the influence of the too high temperature of the cutting disc 22 on the service life.

[0069] The shielding member 31 is semi-circular. A groove 311 is formed on the bottom surface of the shielding member 31, and the groove 311 is semi-circular. The semi-circular shape of the shielding member 31 prevents the shielding member 31 from being too large and affecting the cutting depth of the cutting blade 22. The arc surface of the shielding member 31 faces upward. Part of the cutting blade 22 is located in the groove 311, and part extends from the bottom surface of the shielding member 31. When the cutting depth is not deep, cooling water is sprayed onto the cutting blade 22 through the water outlet hole 323 during the rotation of the cutting blade 22 for cutting. The rotation of the cutting blade 22 will bring the cooling water to the position where the cutting blade 22 contacts the concrete, facilitating the cooling of the cutting blade 22. The rotation of the cutting blade 22 will cause the cooling water to splash. At this time, the shielding member 31 can shield the splashing cooling water.

[0070] An arc-shaped plate 32 is arranged below the inner top surface of the groove 311, and the arc-shaped plate 32 is in contact with the side wall of the groove 311. One end surface of the arc-shaped plate 32 is connected to the inner top surface of the groove 311 through a connecting plate 321, so as to form an arc-shaped chamber between the arc-shaped plate 32 and the inner top surface of the groove 311, and the other end of this chamber is open. The length of the arc-shaped plate 32 is less than the length of the inner top surface of the groove 311. The arc-shaped strip 33 can slide in the arc-shaped chamber and can extend out from the open end of the chamber, and then extend out from the bottom surface of the shielding member 31, increasing the part for shielding the splashing of the cooling water. The arc-shaped strip 33 extending out from the bottom surface of the shielding member 31 can block the splashing of the cooling water generated during the rotation and cutting of the cutting blade 22.

[0071] A scraping strip 322 is arranged on the top surface of the arc-shaped plate 32, and the scraping strip 322 is arranged close to the other end surface of the arc-shaped plate 32. When the arc-shaped strip 33 extending out from the bottom surface of the shielding member 31 needs to rotate towards the inside of the shielding member 31, the scraping strip 322 will contact the bottom surface of the arc-shaped strip 33 and scrape off the splashing cooling water blocked by the arc-shaped strip 33 and the impurities remaining on the bottom surface of the arc-shaped strip 33.

[0072] The arc-shaped plate 32 is provided with a water outlet hole 323, and the water outlet hole 323 is arranged close to the connecting plate 321. Through the water outlet hole 323, the cooling water can be directly sprayed onto the cutting blade 22.

[0073] An arc-shaped hole 312 is formed on the arc-shaped surface of the shielding member 31. The arc-shaped hole 312 communicates with an arc-shaped chamber. An arc-shaped strip 33 is slidably disposed in the arc-shaped chamber. A grip 331 is provided on the top surface of the arc-shaped strip 33. The grip 331 passes through the arc-shaped hole 312 and extends out of the arc-shaped surface of the shielding member 31. A plurality of blocks 313 are equidistantly arranged on the arc-shaped surface of the shielding member 31. A card slot 314 is formed on the surface of the block 313 facing the grip 331. A convex block 332 is provided on the surface of the grip 331 facing the block 313. The convex block 332 is connected to the inner wall of the receiving groove formed in the grip 331 through a first spring. The convex block 332 is adapted to the card slot 314. A bellows is provided between the grip 331 and the inner wall of the arc-shaped hole 312. The top surface of the arc-shaped strip 33 contacts the inner top surface of the groove 311, and the side wall of the arc-shaped strip 33 contacts the side wall of the groove 311. A protrusion 333 is provided on the bottom surface of the arc-shaped strip 33. The protrusion 333 contacts the top surface of the arc-shaped plate 32. A flow channel 334 is formed inside the arc-shaped strip 33. Both ends of the flow channel 334 are located at both ends of the arc-shaped strip 33. A connector 335 is provided at one end of the arc-shaped strip 33 close to the connecting plate 321. The rotation of the arc-shaped strip 33 can be driven by the grip 331, and the grip 331 facilitates the rotation of the arc-shaped strip 33. After the arc-shaped strip 33 rotates to the required position, the arc-shaped strip 33 is fixed by inserting the convex block 332 into the corresponding card slot 314 to prevent the arc-shaped strip 33 from moving. The bellows can prevent the cooling water in the chamber from flowing out through the strip-shaped holes. The connector 335 can be connected to the water pipe 36 so that the water in the water pipe 36 enters the flow channel 334. The contact between the arc-shaped strip 33 and the inner wall of the chamber can prevent the cooling water from flowing out of the gap between the arc-shaped strip 33 and the chamber after entering the chamber.

[0074] When the cutting depth is less than the preset standard depth, it is determined at this time that the water supply pressure of the water pump is low. The arc-shaped strip 33 is driven to move by the grip 331, and the arc-shaped strip 33 moves away from the water outlet hole 323. One end of the arc-shaped strip 33 will pass through the opening of the arc-shaped chamber and extend from the bottom surface of the shielding member 31, so as to shield the cooling water splashing during the cutting process of the cutting blade 22. The cooling water in the water pipe 36 will flow into the chamber. At this time, the joint 335 is not connected to the water pipe 36, and the joint 335 moves away from the water pipe 36. At this time, the water outlet hole 323 is exposed, and the water outlet hole 323 is closer to the water outlet end of the water pipe 36 than the joint 335. The cooling water entering the chamber will drip on the cutting blade 22 through the water outlet hole 323 for cooling;During the cutting process, the cutting depth may need to be adjusted. When the cutting depth is greater than the preset standard depth, it is determined that the water supply pressure of the water pump is high at this time. At this time, the water supply pressure of the water pump increases. The operator can manually press the convex block 332 into the receiving groove, so that the convex block 332 leaves the clamping groove 314. At this time, the arc-shaped strip 33 can move. The arc-shaped strip 33 is driven to rotate by the handle 331. The arc-shaped strip 33 moves toward the connecting plate 321, so that the joint 335 can be connected to the water outlet end of the water pipe 36. After the arc-shaped strip 33 moves in place, the convex block 332 is made to enter the corresponding clamping groove 314 again. When the convex block 332 enters the clamping groove 314, the first spring is still in a compressed state, so that the convex block 332 is in close contact with the clamping groove 314 to prevent the arc-shaped strip 33 from moving. When the arc-shaped strip 33 moves toward the connecting plate 321, the scraping strip 322 can scrape off impurities and the like remaining from the cooling water splashing on the bottom surface of the arc-shaped strip 33. And as the arc-shaped strip 33 rotates, the protrusion 333 will block the water outlet hole 323. At this time, the cooling water remaining between the baffle and the arc-shaped strip 33 will be squeezed, so that the pressure of the cooling water remaining between the baffle and the arc-shaped strip 33 on the outer wall of the water pipe 36 increases. Since the pressure of the cooling water in the water pipe 36 increases due to the increase in the pressure of the water pump, the increase in the pressure of the cooling water in the water pipe 36 on the water pipe 36 may cause the connection position between the hose and the rigid part of the water pipe 36 to form a bulge due to the increase in water pressure, which is likely to cause damage to the water pipe 36. By squeezing the cooling water remaining between the baffle and the arc-shaped strip 33, the inward pressure of this part of the cooling water on the outer wall of the water pipe 36 increases to offset part of the outward pressure of the cooling water in the water pipe 36 on the water pipe 36, avoiding bulging deformation of the water pipe 36. After the water pipe 36 is connected to the joint 335, the cooling water in the water pipe 36 enters the chamber through the flow channel 334 and is sprayed out from the bottom surface of the shielding part 31 after being guided by the shape of the chamber. When the cooling water flows through the opening of the chamber, it can wash the scraping strip 322. When the cutting depth is relatively deep, the part of the cutting blade 22 away from the first moving component will be inclined to facilitate cutting a deeper depth. At this time, if the cooling water is sprayed onto the cutting blade 22 through the water outlet hole 323, the cutting blade 22 cannot bring the cooling water to the deeper cutting position. Therefore, the cooling water is guided through the chamber and directly sprayed between the cutting blade 22 and the concrete, so that the cooling water can be sprayed into the deeper cutting position and directly on the position where the cutting blade 22 contacts and cuts the concrete, ensuring the effect of cooling and heat dissipation.;

[0075] The cooling mechanism includes: a water pipe 36 and a water pump; one end of the water pipe 36 passes through the top surface of the shielding member 31 and extends into the chamber, and the end of the water pipe 36 extending into the chamber is close to the water outlet hole 323; the other end of the water pipe 36 is communicated with the liquid storage chamber 12 arranged in the housing 1 through the water pump; the water pump can pump the cooling water in the liquid storage chamber 12 into the water pipe 36; the pressure of the water pumped by the water pump can be adjusted to adapt to the cooling requirements of cutting at different depths; one end of the water pipe 36 extending into the chamber can be connected to the inner wall of the chamber through a plurality of connecting bars 361, so that the position of the end of the water pipe 36 extending into the chamber is fixed, which is convenient for the connection between the joint 335 and the water pipe 36 during the movement of the arc-shaped bar 33; there is a gap between adjacent connecting bars 361, so that the cooling water can flow in the chamber; an arc-shaped guiding surface can be arranged on the outer wall of the end of the water pipe 36 extending into the chamber, which is convenient for the joint 335 to be smoothly sleeved on the water pipe 36 through the guidance to complete the connection; one end of the water pipe 36 extending into the chamber can be rigid, and the rest is a flexible pipe, and the rigid part is convenient for connecting with the joint 335 and for fixing.

[0076] A liquid replenishing port 11 communicated with the liquid storage chamber 12 is arranged on the housing 1 to replenish water into the liquid storage chamber 12 to ensure that the cooling water can be cooled for a long time.

[0078] The driving motor 21 can adopt a DC brushless motor, which is directly connected with the cutting blade 22 after being decelerated by a speed reducer, and a lithium battery is used as the power supply, so that this concrete cutting device can work continuously in a closed environment. Detection devices such as a sensor assembly and a detector can be arranged on the concrete cutting device to detect concrete information or receive the concrete information sent by an external terminal wirelessly. After judging the pouring year of the concrete during use and inputting and feeding back to the controller through the instrument for information processing, the output speed and torque of the driving motor 21 are automatically adjusted by the controller, ensuring the optimal state of the cutting work.

The first moving component is arranged farther away from the cutting disc 22 than the second moving component; the first moving component includes: a first connecting shaft 23 and a pair of first rollers 24; the connecting shaft is arranged on the housing 1; the first rollers 24 are rotatably connected to the first connecting shaft 23, and the lowest point of the first rollers 24 is lower than the lowest point of the housing 1; the second moving component includes: a second connecting shaft 25 and a pair of second rollers 26; the second rollers 26 are rotatably arranged on the second connecting shaft 25; the first connecting shaft 23 is connected to the first connecting shaft 23 through a connecting piece 27, that is, the second connecting shaft 25 passes through the connecting piece 27 and is fixedly connected to the connecting piece 27, the first connecting shaft 23 passes through the connecting piece 27, and the first connecting shaft 23 is rotatably connected to the connecting piece 27; the concrete cutting device 2 can be driven to move through the first moving component and the second moving component to meet the length requirement of concrete cutting.
