Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1

[0036] Please refer to Figure 1 - Figure 12As shown, a roofing leveling device for building construction includes a long rod 1. A connecting block 45 is fixedly connected to the bottom end of the long rod 1. A fixed base 22 is fixedly connected to the bottom end of the connecting block 45. The front end of the connecting block 45 is close to the top end of the scraping plate 20. A driving mechanism is arranged inside the fixed base 22. The driving mechanism is used to drive the scraping plate 20 to slide on the fixed base 22. A fixing mechanism is arranged at the top end of the scraping plate 20. The fixing mechanism is used to fix the scraping plate 20. A starting mechanism is arranged inside the long rod 1. The starting mechanism can facilitate controlling the forward and reverse rotation of the servo motor 27, so that the scraping plate 20 can slide in different directions;

[0037] Further, the driving mechanism includes a T-shaped plate 23. The T-shaped plate 23 is fixedly connected to the rear end of the scraping plate 20. A rubber pad 24 is fixedly connected to the T-shaped plate 23. The rubber pad 24 abuts against the runner 26. The runner 26 is fixedly connected to the output shaft of the servo motor 27. The servo motor 27 is fixedly connected inside the fixed base 22. A sliding groove 25 is opened at the front end of the fixed base 22. An inclined surface is opened at the rear end of the fixed base 22. The T-shaped plate 23 is slidably connected inside the sliding groove 25. The inner wall of the sliding groove 25 fits with the T-shaped plate 23. The scraping plate 20 is designed in an overall L shape. A wiring hole 35 is opened at the top end of the fixed base 22. The wiring hole 35 communicates with the inside of the fixed base 22. A first wiring 29 is inserted into the wiring hole 35. The top end and the bottom end of the first wiring 29 are electrically connected to the controller inside the control box 30 and the servo motor 27 respectively;

[0038] Through the structural design of the driving mechanism, the function of adjusting the length of the scraping plate 20 during the process of scraping the concrete by the scraping plate 20 is realized. So that when scraping the concrete at the edge of the roof, the worker can stay away from the roof edge, thereby improving the safety during the construction process. During work, the bottom end of the long rod 1 is connected to the fixed base 22 through the connecting block 45. When adjusting the length of the scraping plate 20 on the fixed base 22, first start the servo motor 27 inside the fixed base 22 to drive the rotating wheel 26 to rotate. The rotating wheel 26 abuts against the rubber pad 24 fixed on the T-shaped plate 23. The rubber pad 24 can increase the friction with the rotating wheel 26 to ensure that the rotation of the rotating wheel 26 can stably drive the T-shaped plate 23 to slide inside the sliding groove 25. The T-shaped plate 23 is fixed on the scraping plate 20. Therefore, the scraping plate 20 will slide on the fixed base 22 to move the scraping plate 20 to one side of the fixed base 22. At this time, when scraping the concrete at the edge position of the roof, the worker can stay away from the roof edge, improving the safety during the construction process. Among them, the servo motor 27 is fixed inside the fixed base 22. A wiring hole 35 is opened at the top end of the fixed base 22 to facilitate the connection of the first wiring 29 to the servo motor 27 inside the fixed base 22. An inclined surface is opened at the rear end of the fixed base 22 to facilitate better pushing of the concrete.

[0039] Furthermore, the fixing mechanism includes a lifting plate 43. Two groups of clamping blocks 44 are fixedly connected to the bottom end of the lifting plate 43. The clamping blocks 44 are inserted into the internal of the clamping grooves 50. The clamping grooves 50 are opened at the top end of the scraping plate 20. Multiple groups of the clamping grooves 50 are opened. Two groups of guide rods 46 are inserted into the top end of the lifting plate 43. The top ends of the guide rods 46 are fixedly connected to the inner wall of the long rod 1. A pulling rod 42 is fixedly connected to the top end of the lifting plate 43. The top end of the pulling rod 42 is rotatably connected to the connecting rod 41. The top end of the connecting rod 41 is rotatably connected to the disc 38. The disc 38 is fixedly connected to the small gear 37. The small gear 37 is rotatably connected to the fixed rod 36. One side of the fixed rod 36 away from the small gear 37 is fixedly connected to the inner wall of the long rod 1. The small gear 37 meshes with the large gear 40. The large gear 40 is fixedly connected to the rotating block 54. The large gear 40 is rotatably connected to the support rod 39. Both sides of the support rod 39 are fixedly connected to the inner wall of the long rod 1;

[0040] Through the structural design of the fixing mechanism, during the process of the rotating block 54 abutting against the start button 59, the pulling rod 42 will pull the lifting plate 43 to slide inside the long rod 1, so that the clamping block 44 is withdrawn from the clamping groove 50, releasing the fixation of the scraping plate 20, enabling the scraping plate 20 to slide smoothly on the fixed base 22. At the same time, after the length adjustment of the scraping plate 20 is completed, the clamping block 44 can be inserted back into the clamping groove 50 to fix the scraping plate 20, ensuring that the position of the scraping plate 20 does not move during work. During work, since the rotating block 54 is connected to the large gear 40, the rotation of the rotating block 54 will drive the large gear 40 to rotate synchronously. The bottom end of the large gear 40 meshes with the small gear 37. Therefore, a relatively small rotation angle of the large gear 40 will cause a relatively large rotation angle of the small gear 37 on the fixed rod 36. The small gear 37 is connected to the disc 38, thus driving the disc 38 to rotate. The rotating connecting rod 41 on the disc 38 then pulls the pulling rod 42 upward. The bottom end of the pulling rod 42 is fixed with a lifting plate 43. At this time, the clamping block 44 fixed to the bottom end of the lifting plate 43 will move away from the scraping plate 20 and finally no longer be inserted into the clamping groove 50. At this time, the fixation of the scraping plate 20 can be released, and the scraping plate 20 can slide smoothly on the fixed base 22 to adjust the length. Two guide rods 46 are inserted on the lifting plate 43 to guide the movement of the lifting plate 43 through the guide rods 46.

[0041] Further, the starting mechanism includes two rotating blocks 54. Two linkage rods 53 are rotatably connected to each of the rotating blocks 54. The rotating blocks 54 are rotatably connected to the support rod 39. The linkage rods 53 are slidably connected inside the through groove 60. The through groove 60 is opened inside the long rod 1. The bottom end of the bottom rotating block 54 is close to the start button 59. There are two start buttons 59. The start buttons 59 are slidably connected to the button housing 33. The button housing 33 is fixedly connected to the support frame 34. The top end of the support frame 34 is fixedly connected to the support rod 39 rotatably connected to the bottom rotating block 54. The bottom end of the button housing 33 is inserted with a second wiring 32. The bottom end of the second wiring 32 is electrically connected to the controller inside the control box 30. The top end of the control box 30 is fixedly connected to the fixed rod 36. Two connecting columns 55 are fixedly connected to the top rotating block 54. The front ends of the connecting columns 55 are slidably connected inside the arc-shaped groove 61. The arc-shaped groove 61 is opened at a position close to the top of the long rod 1. The side of the connecting column 55 away from the rotating block 54 is fixedly connected to the knob 58;

[0042] Through the structural design of the starting mechanism, by turning the knob 58 clockwise and counterclockwise, the bottom end of the rotating block 54 will respectively abut against one of the starting buttons 59, and the servo motor 27 will be started by pressing the starting button 59. The two starting buttons 59 respectively control the forward and reverse rotation of the servo motor 27, so as to facilitate the sliding of the scraping plate 20 to the left or right on the fixed base 22, making the adjustment of the scraping plate 20 more convenient and flexible. During work, first rotate the knob 58 clockwise or counterclockwise. The knob 58 is connected to the top rotating block 54 through two connecting columns 55. The rotation of the knob 58 will drive the top rotating block 54 to rotate synchronously. Since two linkage rods 53 are rotatably connected to the two rotating blocks 54, the bottom rotating block 54 will also rotate by the same angle. The linkage rod 53 is slidably connected inside the through groove 60. The length of the through groove 60 is greater than the width of the linkage rod 53 to ensure that the linkage rod 53 can move and slide normally inside the through groove 60. During the process of the bottom rotating block 54 rotating to one side, the bottom rotating block 54 will abut against one of the starting buttons 59 and push the starting button 59 to slide inside the button housing 33. When the starting button 59 slides to the maximum position, the circuit inside the control box 30 will be connected, and the servo motor 27 will be started. The two starting buttons 59 respectively control the forward and reverse rotation of the servo motor 27. Therefore, by rotating the knob 58 in different directions, the scraping plate 20 can be slid in different directions on the fixed base 22. When the rotating block 54 is in a horizontal state relative to the two starting buttons 59, the servo motor 27 will stop rotating. Since the rotation of the bottom rotating block 54 is transmitted to the small gear 37 through the large gear 40 to drive the disc 38 to rotate, the clamping block 44 can be separated from the card slot 50 before the starting button 59 slides down to the maximum position to start the servo motor 27.

[0043] Further, a rubber ring 57 is sleeved outside the knob 58. The rubber ring 57 is fixedly connected to the inner wall of the fixing ring 56. The fixing ring 56 is fixedly connected to the long rod 1. A notch is provided on one side of the fixing ring 56 and the rubber ring 57.

[0044] During work, the fixing ring 56 is fixed on the long rod 1 to protect the knob 58. And a rubber ring 57 is fixed on the inner wall of the fixing ring 56. The rubber ring 57 is sleeved on the knob 58, which can provide frictional resistance for the rotation of the knob 58 to ensure that the knob 58 will not rotate due to small vibrations. Notches are provided on one side of the fixing ring 56 and the rubber ring 57 to facilitate the rotation of the knob 58 through the notches.

[0045] Further, the top end of the inner wall of the long rod 1 is threadedly connected with an extension rod 52. The bottom end of the extension rod 52 is close to the cover plate 62. The cover plate 62 is fixedly connected to the inner wall of the long rod 1.

[0046] During operation, the extension rod 52 is used to extend the length of the top end of the long rod 1, and a cover plate 62 is also fixed on the inner wall of the long rod 1. When the extension rod 52 is removed from the top end of the long rod 1, the cover plate 62 can provide shielding for the top end rotating block 54 to reduce the interference of the rotating block 54 by external factors.

[0047] Further, fixed columns 31 are fixedly connected to both the left and right sides of the control box 30, and the fixed columns 31 are fixedly connected to the inner wall of the long rod 1;

[0048] During operation, both sides of the control box 30 are fixedly connected to the inner wall of the long rod 1 through the fixed columns 31, so that the fixing effect of the control box 30 inside the long rod 1 is better. At the same time, the bottom end of the fixed rod 36 can also be supported to a certain extent through the connection with the control box 30.

[0049] Further, two sets of movable grooves 47 are opened at the front end of the fixed base 22. A spring 48 is fixedly connected inside the movable groove 47. The front end of the spring 48 is fixedly connected to a spherical member 49. The spherical member 49 is clamped inside a semi-circular groove 51. The semi-circular groove 51 is opened at the rear end of the scraping plate 20, and multiple sets of semi-circular grooves 51 are opened;

[0050] During operation, multiple sets of semi-circular grooves 51 are opened at the rear end of the scraping plate 20. When the scraping plate 20 slides, the spherical member 49 originally inserted inside the semi-circular groove 51 will slide out of the semi-circular groove 51 and abut against the scraping plate 20. While the spring 48 is compressed, the spherical member 49 will also be received inside the movable groove 47. When the scraping plate 20 slides to align the next set of semi-circular grooves 51 with the spherical member 49, at this time, the spherical member 49 can, under the action of the spring 48, be re-clamped inside the semi-circular groove 51, so that the worker can judge whether the card slot 50 is aligned with the card block 44 through the sound generated by the collision between the inner wall of the semi-circular groove 51 and the spherical member 49, so as to facilitate the subsequent insertion of the card block 44 into the card slot 50 to fix the scraping plate 20.

[0051] Embodiment 2

[0052] Please refer to Figure 2 and Figure 6 As shown, as another implementation manner of the present invention for comparing with Embodiment 1, two sets of limit blocks 21 are fixedly connected to both the left and right sides of the scraping plate 20, and the limit blocks 21 are horizontal with the left and right sides of the scraping plate 20;

[0053] During operation, the limit blocks 21 are fixed on both the left and right sides of the scraping plate 20 to limit the moving distance of the scraping plate 20 and prevent the scraping plate 20 from sliding too far and separating from the fixed base 22.

[0054] The lifting plate 43 fits against the inner wall of the connecting block 45, and the guide rod 46 is designed in an overall L shape;

[0055] During operation, an arc surface is provided on the lifting plate 43 to facilitate fitting against the inner wall of the connecting block 45. The guide rod 46 is designed in an overall L shape and is used to guide the movement of the lifting plate 43.
