[0015] Beneficial effects

[0016] This invention provides a roughening device for concrete surface treatment. Compared with the prior art, it has the following advantages: (1) By setting up a chiseling mechanism, the meshing of the worm gear and the worm can be used to adjust the overall length of the vertical rod and the chiseling head by rotating the screw. This allows for chiseling at different depths, and the chiseling head can be replaced by the stud. The curved surface can be chiseled by the vertical rod of different overall lengths, thus improving the applicability of the device. At the same time, a single linear motor drives the movement of the abutment. The vertical rod can be adjusted individually by the contact between the abutment and the corresponding spiral groove inside the worm, further improving the convenience of the device.

[0017] (2) By setting up a drive assembly, using a dual-shaft motor and intermittent transmission with missing gears, and through the meshing of two flat gears, one end of the telescopic rods on both sides swings upward, and through the contact of the sliding sleeve and the pin, the pin drives the vertical rod to move upward intermittently through the horizontal rod, and then descends through the gravity of the vertical rod and other structures. This can achieve the roughening treatment of the concrete surface, and avoid the problem of damage to the roughening head caused by the hard surface.

[0018] (3) By setting up a spray unit, the meshing of the toothed ring and the missing gear makes the spool intermittently driven to rotate, so as to achieve intermittent winding of the cable. Then, the water frame descends under its own gravity, so that the water frame quantitatively transfers the liquid water inside the water tank through reciprocating lifting and lowering. And through the connection of the overflow holes on both sides, the liquid water flows into the solid tank, thereby achieving quantitative spraying to ensure consistent spraying effect.

[0019] (4) By setting up connecting components, the connecting rod and the sliders on both sides are connected together, which not only improves the lateral compressive strength of the vertical rod, but also facilitates the adjustment of the vertical position of the vertical rod. At the same time, the baffle can block the slide groove, preventing dust from entering the slide groove during roughening. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-6 The present invention provides a technical solution: a roughening device for concrete surface treatment. The device includes a housing 1, with shock-absorbing casters and a handle (not shown in the figure) on the outside. Inside the housing 1 is a roughening mechanism, including a crossbar 2. The crossbar 2 is hollow and houses a battery, control circuit, and remote control module. The crossbar 2 is fixed to the lower part of the housing 1 via a spring rod, which maintains the relative position of the crossbar 2 when stationary. The outer surface of the crossbar 2 is movably connected to the interior of the housing 1. A vertical rod 4 is movably connected to the outer surface of the crossbar 2. One end of the vertical rod 4 is slidably connected to the body of the housing 1 and extends to the bottom of the housing 1. A lead screw 6 is rotatably connected inside the crossbar 2. The lead screw 6, through a threaded connection with the vertical rod 4, allows adjustment of the overall length of both, enabling different roughening depths. Furthermore, the vertical rod 4 can be individually adjusted to accommodate curved surfaces. The vertical rod 4 is roughened by chiseling, and the connection between the lead screw 6 and the crossbar 2 is provided with axial limiting measures. One end of the lead screw 6 is threadedly connected to the top of the vertical rod 4, and the other end of the lead screw 6 is fixedly connected to the worm wheel 7. The outer surface of the worm wheel 7 is rotatably connected to the inside of the crossbar 2. The outer surface of the worm wheel 7 is meshed with the worm 11. The meshing of the worm wheel 7 and the worm 11 can drive the lead screw 6 to adjust the position of the vertical rod 4, and can also improve the stability of the vertical rod 4 through the self-locking function. At the same time, the worm 11 is hollow, and the outer surface of the worm 11 is rotatably connected to the support plate 8. The connection between the support plate 8 and the worm 11 is provided with axial limiting measures. The outer surface of the support plate 8 is fixedly connected to the inside of the crossbar 2. One end of the vertical rod 4 is fixedly connected to the chisel head 10 by the stud 9. The chisel head 10 and the stud 9 are fixed together by welding to form a modular structure, which facilitates the quick disassembly and replacement of the chisel head 10.

[0024] The worm gear 11 has a slide rail 12 inside, and the two ends of the slide rail 12 are fixedly connected to the inside of the crossbar 2. The worm gear 11 has a helical groove 13 inside. A linear motor 14 is slidably connected to the outer surface of the slide rail 12. The linear motor 14 has a self-locking function and is electrically connected to the control circuit. A stop post 15 is fixedly connected to the outer surface of the linear motor 14. One end of the stop post 15 is chamfered to reduce the helical contact with the helical groove 13. The worm gear 11 is driven to rotate by the contact action. One end of the stop post 15 is in contact with the inside of the helical groove 13.

[0025] By setting up a chiseling mechanism, the meshing of the worm gear 7 and the worm 11 allows the screw 6 to rotate, adjusting the overall length of the vertical rod 4 and the chiseling head 10. This enables chiseling at different depths and allows the chiseling head 10 to be replaced via the stud 9. Furthermore, by using vertical rods 4 of different overall lengths, the curved surfaces can be chiseled, thus expanding the applicability of the device. At the same time, a single linear motor 14 drives the abutment 15 to move. Through the contact between the abutment 15 and the corresponding spiral groove 13 inside the worm 11, the vertical rod 4 can be adjusted individually, further enhancing the convenience of the device.

[0026] A drive assembly 3 is provided on the outside of the crossbar 2. The drive assembly 3 includes a dual-axis motor 31. The outer surface of the dual-axis motor 31 is fixedly connected to the inside of the housing 1. Both ends of the dual-axis motor 31 are fixedly connected to a missing gear 32. The missing gear 32 can provide intermittent drive. Two meshing spur gears 34 are provided on the outside of one side of the missing gear 32. The two spur gears 34 are arranged with one large and one small, which can facilitate the meshing of the larger spur gear 34 with the missing gear 32, so that the two spur gears 34 can rotate synchronously in opposite directions. The shaft ends of the two spur gears 34 are embedded and rotatably connected to the inside of the housing 1. The outer surface of one side of the missing gear 32 meshes with the outer surface of the larger spur gear 34. The outer surfaces of the two spur gears 34 are fixedly connected to a telescopic rod 35. The telescopic rods 35 corresponding to the large and small spur gears 34 are one short and one long, so as to ensure that the longitudinal displacement length of one end of the two is the same.

[0027] One end of each of the two telescopic rods 35 is rotatably connected to a sliding sleeve 36. The inside of each of the two sliding sleeves 36 is slidably connected to a pin 37. The larger end of the sliding sleeve 36 and the pin 37 abuts against each other, which can push the crossbar 2 and the chisel head 10 to rise. One end of each of the two pins 37 is fixedly connected to the outer surface of the crossbar 2.

[0028] By setting up the drive assembly 3, using the intermittent transmission of the dual-shaft motor 31 and the missing gear 32, and through the meshing of the two spur gears 34, one end of the telescopic rods 35 on both sides swings upward. Through the contact between the sliding sleeve 36 and the pin 37, the pin 37 drives the vertical rod 4 to move upward intermittently through the horizontal rod 2. Then, the vertical rod 4 and other structures descend by their own gravity. This can achieve the roughening treatment of the concrete surface and avoid the problem of damage to the roughening head 10 caused by surfaces with high hardness.

[0029] A spray unit 33 is provided outside the dual-axis motor 31. The spray unit 33 includes a fixed box 331. An existing blower and hood structure (not shown in the figure) are also provided between the fixed box 331 and the vertical rod 4. As a preferred method, the fixed box 331 can be additionally equipped with pressurization measures to increase the spray pressure. The outer surface of the fixed box 331 is fixedly connected to the body of the box 1. A through spray hole 332 is opened at the bottom of the fixed box 331. Multiple spray holes 332 are arranged in a row at equal intervals. The inner diameter of the spray holes 332 is the same. A water tank 334 is fixedly connected inside the fixed box 331 through a filter plate 333. The top of the water tank 334 is lower than the top of the fixed box 331 and stores liquid water inside. The filter plate 333 can both support the water tank 334 and facilitate the flow of liquid water.

[0030] A water frame 335 is slidably connected inside the water tank 334. The external dimensions of the water frame 335 are adapted to the internal dimensions of the water tank 334, and it is made of a material that is pressure-resistant, wear-resistant, corrosion-resistant, and has good sealing properties. A one-way valve 336 is fixedly connected through the bottom of the water frame 335. The one-way valve 336 allows liquid water inside the water tank 334 to flow into the water frame 335 in one direction when the water frame 335 is lowered. The interior of the one-way valve 336 is connected to the interior of the water tank 334. Both the body of the water frame 335 and the top of the water tank 334 are provided with through overflow holes 337. The inner diameter of the overflow hole 337 is much larger than the inner diameter of the spray hole 332 to ensure the amount of water flowing into the solid tank 331, thereby ensuring the uniformity and consistency of the spray. The interiors of the overflow holes 337 on both sides are connected.

[0031] Two reels 338 are installed above the water frame 335. The shaft ends of the two reels 338 are rotatably embedded in the interior of the housing 1. The outer surfaces of the two reels 338 are fixedly connected with toothed rings 339. The outer surfaces of the two toothed rings 339 mesh with each other. The outer surface of one toothed ring 339 meshes with the outer surface of the missing gear 32 on the other side. Cables are wound around the outer surfaces of the two reels 338. The cables lift the water frame 335 by winding the reels 338. The cables can be connected to the reels 338 by the guidance of a fixed pulley. The fixed pulley is fixed to the inner wall of the housing 1. One end of each cable is fixedly connected to the two sides of the top of the water frame 335.

[0032] By setting up a spray unit 33, the meshing of the gear ring 339 and the missing gear 32 causes the spool 338 to be intermittently driven to rotate, thereby achieving intermittent winding of the cable. Then, the water frame 335 descends under its own gravity, causing the water frame 335 to reciprocate and quantitatively transfer the liquid water inside the water tank 334. Through the connection of the overflow holes 337 on both sides, the liquid water flows into the solid box 331, thereby achieving quantitative spraying to ensure consistent spraying effect.

[0033] The external part of the vertical rod 4 is provided with a connecting component 5, which includes a slide groove 51. The slide groove 51 is formed on the outer surface of two adjacent vertical rods 4 that are close to each other. A slider 52 is slidably connected inside the slide groove 51. The slider 52 has a T-shaped cross-section to improve the stability of the connection with the vertical rod 4. A connecting rod 53 is fixedly connected between the outer surfaces of two adjacent sliders 52. The connecting rod 53 plays a lateral connection role between two adjacent vertical rods 4.

[0034] Two baffles 54 are fixedly connected through the outer surface of the connecting rod 53. The baffles 54 are made of pressure-resistant and wear-resistant material and are longer than the inner height of the slide groove 51. They prevent impurities from entering the slide groove 51 and affecting the sliding of the slider 52. The outer surfaces of the two baffles 54 are movably connected to the outer surfaces of the two vertical rods 4. Magnetic columns 55 are embedded and fixedly connected to the outer surface of the slider 52 and the inside of the slide groove 51. The magnetic columns 55 on both sides are made of permanent magnets and, through magnetic repulsion, make the slider 52 suspend in the middle position inside the slide groove 51, so as to facilitate the position adjustment of the vertical rod 4.

[0035] By setting the connecting component 5, the connecting rod 53 and the sliders 52 on both sides are connected together, which not only improves the lateral pressure resistance of the vertical rod 4, but also facilitates the adjustment of the vertical position of the vertical rod 4. At the same time, the baffle 54 can block the slide groove 51, preventing dust from entering the slide groove 51 during roughening.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: First, according to the shape of the concrete surface to be roughened, select the appropriate roughening head 10 and install it at the bottom of the vertical rod 4 through the action of the stud 9. Then, push the box 1 to move to the concrete surface to be roughened. During roughening, the dual-shaft motor 31 drives the two side gears 32 to rotate. One of the gears 32 meshes with the larger spur gear 34 to drive it to rotate synchronously. At the same time, the two spur gears 34 mesh to drive the two telescopic rods 35 to rotate synchronously in opposite directions. This causes one end of the telescopic rod 35 to drive the sliding sleeve 36 to move upward. When the sliding sleeve 36 abuts against the larger end of the pin 37, the pin 37 drives the horizontal rod 2 to rise synchronously, thereby causing the vertical rod 4 to drive the roughening head 10 to rise synchronously. During the process of the vertical rod 4 and the roughening head 10 rising. The linear motor 14 slides along the slide rail 12, thereby driving the abutment 15 to move synchronously. Through the contact between the abutment 15 and the spiral groove 13, the worm 11 rotates. Then, through the meshing of the worm 11 and the worm wheel 7, the lead screw 6 rotates. Through the threaded connection between the lead screw 6 and the vertical rod 4, the vertical rod 4 slides along the lead screw 6, thus adjusting the overall length of the two. This allows the chisel head 10 to chisel the curved surface or perform chiseling treatment at different depths. Then, when the missing gear 32 disengages from the contact with the flat gear 34, the horizontal bar 2 and the chisel head 10 descend under gravity, allowing the chisel head 10 to chisel the concrete surface. After chiseling, the elastic force of the spring rod cancels out the force, and the horizontal bar 2 and the chisel head 10 return to their original positions. Then, the above steps are repeated to perform continuous chiseling treatment. When the vertical rod 4 is adjusted, the connection between the sliders 52 on both sides and the connecting rod 53 makes the two adjacent vertical rods 4 connected as one, thereby axially limiting the vertical rod 4 so that it can only slide along the lead screw 6. When the vertical rod 4 is adjusted, the baffle 54 keeps blocking the slide groove 51 to prevent impurities from entering the interior of the slide groove 51 during the roughening process. During the roughening process, the missing gear 32 on the other side meshes with a toothed ring 339, and then the two toothed rings 339 mesh with each other, causing the two spools 338 to rotate synchronously to wind the two cables, thereby raising the water frame 335 through the cables. The water frame 335 then transfers the liquid water inside the water tank 334. When the overflow hole 337 on the water frame 335 is aligned and connected with the overflow hole 337 on the water tank 334, the liquid water inside the water frame 335 flows into the solid box 331 through the overflow hole 337, and then is sprayed onto the roughened concrete surface through the spray hole 332. Then, when the missing gear 32 disengages from the toothed ring 339, the water frame 335 descends due to gravity, thereby allowing the liquid water inside the water tank 334 to enter the water frame 335 through the action of the one-way valve 336. Then, by raising the water frame 335 again, the liquid water is sprayed in a timed and quantitative manner.
