[0027] Example 1

[0028] Reference Figure 1 、 Figure 2 , a processing equipment for waste concrete, including a frame 1, the bottom of the frame 1 and near the four corners are rotatably connected to a roller, which can facilitate the movement of the frame 1. The frame 1 includes a bottom plate 11, a top plate 12 and a mounting frame 13.

The top plate 12 is slidably connected to the mounting frame 13, and a moving device 3 is installed on the top plate 12, which is used to drive the mounting frame 13 to move horizontally, close to or away from the concrete wall panel. The moving direction of the mounting frame 13 is perpendicular to the moving direction of the bottom plate 11. A cutting device 4 is installed on one side of the mounting frame 13, which can cut the discarded concrete wall panel.

[0029] Reference Figure 1 、 Figure 2 The moving device 3 includes a guide rod 31, a moving screw 32, and a moving motor 33. The guide rod 31 is fixedly mounted on the top plate 12, the moving screw 32 is rotatably connected to the top plate 12, and the moving motor 33 is fixedly mounted on the top plate 12 and is located on one side of the top plate 12. The guide rod 31 and the moving screw 32 are parallel to each other and are respectively close to opposite sides of the top plate 12. The guide rod 31 and the moving screw 32 both pass through the mounting frame 13, and the guide rod 31 and the mounting frame 13 are slidably engaged. The moving screw 32 is threadedly connected to the mounting frame 13, and the output shaft of the moving motor 33 is fixedly connected to one end of the moving screw 32. The moving screw 32 is driven to rotate by the moving motor 33, which in turn drives the mounting frame 13 to slide along the length direction of the moving screw 32.

[0030] Reference Figure 1 、 Figure 2 and Figure 3The cutting device 4 includes a cutting frame 41 and a wire saw 42. The cutting frame 41 is rotatably mounted on the mounting frame 13. The cutting frame 41 is in the shape of an elongated strip, extending horizontally away from the mounting frame 13. The minor axis of the wire saw 42 is perpendicular to the length of the cutting frame 41. The wire saw 42 is in the shape of an elliptical ring and is rotatably connected to the cutting frame 41. The wire saw 42 is arranged along the length of the cutting frame 41. The cutting frame 41 is equipped with a brake device 5 for driving the wire saw 42 to rotate and cut the concrete wall panel. The frame 1 is equipped with a drive device 6 that can drive the cutting frame 41 to rotate, driving the wire saw 42 to rotate and simultaneously perform circular cutting on the concrete wall panel. The cutting frame 41 is equipped with an adjustment device 7 for adjusting the minor axis distance of the wire saw 42, and thereby adjusting the width of the cut made by the wire saw 42 on the concrete wall panel, so that the concrete wall panel can be cut step by step.

[0031] Reference Figure 2 、 Figure 3 and Figure 4 The adjustment device 7 includes a first guide wheel 71 and a second guide wheel 72. The first guide wheel 71 and the second guide wheel 72 rotate at the two ends of the cutting frame 41, respectively. The diameter of the first guide wheel 71 is larger than that of the second guide wheel 72, and the first guide wheel 71 is located at the end of the cutting frame 41 near the mounting frame 13. Two second guide wheels 72 are arranged at intervals along the width of the cutting frame 41. The axial directions of the first guide wheel 71 and the second guide wheel 72 are perpendicular to the longitudinal direction of the cutting frame 41. The wire rope saw 42 is mounted on the first guide wheel 71 and the second guide wheel 72. Two limiting rings 73 are fixed at each end of the cutting frame 41. The axial directions of the limiting rings 73 are parallel to the longitudinal direction of the cutting frame 41. The wire rope saw 42 passes through the limiting rings 73 and slides with them. A plurality of movable rollers are rotatably connected to the inner circumference of the limiting rings 73. The wire rope saw 42 passes through the plurality of movable rollers and slides with them. The two limiting rings 73 located at each end of the cutting frame 41 are symmetrically arranged about the cutting frame 41, and the center distance between the two limiting rings 73 at one end of the cutting frame 41 is equal to the center distance between the two limiting rings 73 at the other end of the cutting frame 41, so that the two ends of the rope saw 42 can maintain cooperation with the first guide wheel 71 and the second guide wheel 72.

[0032] Reference Figure 2 、 Figure 3Two support mechanisms 74 are rotatably connected to the cutting frame 41. These two support mechanisms 74 are symmetrically arranged about the center of the cutting frame 41. These support mechanisms 74 include two support rods 741, one end of which is rotatably connected to the cutting frame 41, while the other end of each support rod 741 faces the center of the cutting frame 41. The two support rods 741 on the same support mechanism 74 form a V-shape. Specifically, two strip grooves are defined on the upper and lower side walls of the cutting frame 41, one end of each strip groove extending through the end of the cutting frame 41. One end of each support rod 741 is rotatably connected to the strip groove near the end of the cutting frame 41. When the movable end of each support rod 741 rotates, it engages within the strip groove, allowing the entire support rod 741 to be accommodated within the strip groove. The movable end of each support rod 741 is rotatably connected to a guide ring 742. Multiple movable rollers are rotatably connected to the inner circumference of the guide ring 742. The wire saw 42 passes through the guide ring 742 and slidably engages with it. The openings of the two support mechanisms 74 face each other. The larger the opening, the greater the spacing between the short axes of the wire saw 42 located in the middle of the cutting frame 41, and the larger the concrete wall panels that can be cut. The smaller the opening, the smaller the spacing between the short axes of the wire saw 42 located in the middle of the cutting frame 41, and the smaller the concrete wall panels that can be cut. An adjustment mechanism 75 is mounted on the cutting frame 41 to facilitate adjusting the opening size of the support mechanisms 74.

[0033] Reference Figure 2 、 Figure 3 and Figure 4The adjustment mechanism 75 includes a bidirectional lead screw 751, an adjustment rod 752, and two adjustment seats 753. The bidirectional lead screw 751 is rotatably connected to the cutting frame 41, which is hollow. The two ends of the bidirectional lead screw 751 are respectively rotatably engaged with the two ends of the cutting frame 41, and the centerline of the bidirectional lead screw 751 coincides with the centerline of the cutting frame 41. The bidirectional lead screw 751 is arranged along the length of the cutting frame 41, and the two adjustment seats 753 are respectively threadedly connected to the two threaded sections of the bidirectional lead screw 751. The adjustment seats 753 slide along the length of the cutting frame 41. Two adjustment rods 752 are hinged to the opposite sides of the two adjustment seats 753. The adjustment rods 752 correspond to the support rods 741 one by one. The adjustment rods 752 are hinged to the corresponding side of the support rod 741, and the hinged position of the adjustment rods 752 and the support rod 741 is close to the hinged position of the support rod 741 and the cutting frame 41. An adjustment assembly 76 is mounted on the cutting frame 41, which is used to drive the bidirectional lead screw 751 to rotate, thereby adjusting the distance between the two adjustment seats 753. The adjustment assembly 76 includes a first adjustment wheel 761, a second adjustment wheel 762, an adjustment belt 763, and an adjustment motor 764. The first adjustment wheel 761 is fixed to the end of the bidirectional lead screw 751 away from the mounting frame 13, and the second adjustment wheel 762 rotates on the end of the cutting frame 41 away from the mounting frame 13. The adjustment belt 763 is mounted on the first and second adjustment wheels 761 and 762. The adjustment motor 764 is fixed to one side of the cutting frame 41, and the output shaft of the adjustment motor 764 is fixed to the end of the second adjustment wheel 762. By driving the bidirectional lead screw 751 in forward rotation by the adjustment motor 764, the distance between the two adjustment seats 753 can be increased, causing the adjustment rod 752 to lift the support rod 741, driving the movable end of the support rod 741 away from the cutting frame 41, thereby increasing the distance between the short axes of the wire saw 42 located in the middle of the cutting frame 41. When the adjustment motor 764 drives the bidirectional lead screw 751 to reverse, the distance between the two adjustment seats 753 is reduced, bringing the movable end of the support rod 741 closer to the cutting frame 41, thereby reducing the short axis distance of the wire saw 42. The limiting rings 73 correspond one to one with the support rods 741, and each limiting ring 73 is located near the hinged connection between the support rod 741 and the cutting frame 41.

[0034] Reference Figure 3 and Figure 4A tensioning device 8 is mounted on the end of the cutting frame 41 away from the mounting frame 13, enabling timely adjustment of the tension of the wire saw 42. The tensioning device 8 comprises a fixed rod 81, a first fixed block 82, a second fixed block 83, a movable frame 84, and a tensioning cylinder 85. The fixed rod 81 is fixed to one end of the cutting frame 41 and aligned with the length of the cutting frame 41. Two fixed rods 81 are provided at intervals. The first fixed block 82 and the second fixed block 83 are both fixedly mounted on the fixed rod 81, with the first fixed block 82 being closer to the cutting frame 41 and the second fixed block 83 being located away from the cutting frame 41. The movable frame 84 is slidably connected to the fixed rod 81 and slides along the length of the fixed rod 81. The movable frame 84 is located between the first fixed block 82 and the second fixed block 83. A tensioning cylinder 85 is fixed to the first fixed block 82, and the end of the piston rod of the tensioning cylinder 85 is fixed to the movable frame 84. The second guide wheel 72 is rotatably mounted on the movable frame 84. When adjusting the opening of the support mechanism 74, the movable frame 84 can be brought close to the cutting frame 41, so that the wire rope 42 is in a relaxed state, which facilitates adjustment of the wire rope 42. When the opening of the support mechanism 74 is adjusted, the piston rod of the tensioning cylinder 85 is extended to tighten the wire rope 42, making it easier for the wire rope 42 to cut.

[0035] Reference Figure 2 、 Figure 3 and Figure 5 The brake device 5 includes a fixed base 51, a first brake wheel 52, a second brake wheel 53, a brake belt 54, and a brake motor 55. The fixed base 51 is fixed to one end of the cutting frame 41 near the frame 1. The first brake wheel 52 and the second brake wheel 53 are both rotatably connected to the same side of the fixed base 51. The brake belt 54 is mounted on the first and second brake wheels 52, 53. The brake motor 55 is fixed to the other side of the fixed base 51. The first brake wheel 52 is fixed to the first guide wheel 71 via a connecting shaft. The output shaft of the brake motor 55 passes through the fixed base 51 and is fixed to the second brake wheel 53. The brake motor 55 drives the second brake wheel 53 to rotate, which in turn drives the first brake wheel 52 to rotate. The first guide wheel 71 connected to the first brake wheel 52 rotates, thereby driving the rope saw 42 to rotate.

[0036] Reference Figure 2 、 Figure 3 and Figure 5The driving device 6 includes a gear ring 61, a gear 62, a first driving wheel 63, a second driving wheel 64, a driving belt 65 and a driving motor 66. A circular hole is opened on the end surface of the mounting frame 13, and the end of the cutting frame 41 is inserted into the circular hole and rotatably connected to the circular hole. A turntable 43 is fixed to the end of the cutting frame 41 near the mounting frame 13, and the center of the turntable 43 coincides with the center of the cutting frame 41. The gear ring 61 is fixed to one end of the turntable 43 and is coaxially arranged with the turntable 43. A mounting seat 67 is fixedly installed on the side of the mounting frame 13 away from the cutting frame 41. The first driving wheel 63 and the gear 62 are respectively rotatably connected to the two sides of the mounting seat 67, and the first driving wheel 63 and the gear 62 are fixed by a connecting shaft. The second driving wheel 64 is rotatably connected to the mounting frame 13. The driving belt 65 is sleeved on the first driving wheel 63 and the second driving wheel 64. The driving motor 66 is fixed on the mounting frame 13, and the output shaft of the driving motor 66 is fixed to the end of the second driving wheel 64. The second drive wheel 64 is driven by the drive motor 66 to rotate, which drives the first drive wheel 63 to rotate, and the gear 62 connected to the first drive wheel 63 to rotate. Since the gear 62 is engaged with the gear ring 61, it can drive the cutting frame 41 to rotate as a whole, thereby enabling the rope saw 42 to perform circumferential cutting on the concrete wall panel.

[0037] Example 2

[0038] Reference Figure 1-5 On the other hand, an embodiment of the present application discloses a method for using a treatment device for waste concrete, which uses the treatment device in the above technical solution and includes the following six steps.

[0039] S1. Use a cylindrical saw to drill a hole in the concrete wall panel to form a cutting hole. The hole is a circular hole that can pass through the cutting frame 41. At this time, the diameter of the hole is a1.

[0040] S2. Move the frame 1 to a position corresponding to the hole, and drive the cutting frame 41 through the hole by the moving device 3 and insert it into the hole. Move the middle part of the cutting frame 41 to correspond to the hole wall.

[0041] S3. Drive the adjustment device 7, causing the support mechanism 74 to open and the minor axis spacing of the wire rope 42 to be greater than the diameter of the hole. The minor axis spacing of the wire rope 42 is b1, which is greater than a1. By rotating the bidirectional screw 751 in the forward direction, the spacing between the two adjustment seats 753 is increased, thereby widening the opening of the support mechanism 74 and increasing the minor axis spacing of the wire rope 42. While adjusting the opening of the support mechanism 74, the wire rope 42 is simultaneously driven to rotate, cutting the hole wall. After the opening of the support mechanism 74 is adjusted, the tensioning force of the wire rope 42 is simultaneously adjusted using the tensioning device 8, ensuring that the wire rope 42 is taut.

[0042] When adjusting the opening size of the support mechanism 74, quantitative adjustments are made based on the thickness of the concrete wallboard. The larger the opening of the support mechanism 74, the greater the spacing between the short axes of the wire saw 42 located in the middle of the cutting frame 41, and the larger the concrete wallboard that can be cut. The smaller the opening of the support mechanism 74, the smaller the spacing between the short axes of the wire saw 42 located in the middle of the cutting frame 41, and the smaller the concrete wallboard that can be cut.

[0043] S4, start the driving device 6, drive the cutting frame 41 to rotate, and further cut the hole to form a hole with a larger diameter. The hole after cutting has a diameter a2, and a2 is equal to b1.

[0044] S5, repeat step S3, continue to increase the short axis spacing of the wire saw 42 to b2, so that the short axis spacing of the wire saw 42 is larger than the existing large diameter hole a2, and cut the hole wall; repeat step S4 to further enlarge the hole;

[0045] S6. Continue to repeat the action of S5, gradually increase the short axis spacing of the wire saw 42, and gradually cut the holes until the concrete wall panel is cut.
