Description

Technical Field

[0001] This invention relates to the field of roller grinding equipment technology, and in particular to a grinding and processing device for road rollers. Background Technology

[0002] Road rollers are indispensable pieces of machinery in earthmoving engineering. They not only provide the necessary force for soil compaction but also compact road surfaces in road construction, improving their density and smoothness. The key component of a road roller is its compaction system, composed of steel wheels. These wheels can withstand enormous pressure and intense wear, but over time, problems such as wheel wear, cracks, and deformation can occur. These directly affect pressure transmission, reducing the machine's lifespan and efficiency. Therefore, the repair and maintenance of the steel wheels are crucial.

[0003] Existing road roller wheels are prone to rusting due to frequent contact with damp ground during operation. Rusting often occurs over large areas or even all over the surface, making it inconvenient to deal with. In addition, long-term contact with hard objects such as stones during operation makes the wheels prone to wear, cracks, and deformation. In the past, cracks were manually welded together, and the weld seam was then ground and smoothed separately. This process often required manual hand-held equipment, which was not very practical. Summary of the Invention

[0004] The main objective of this invention is to provide a grinding and processing device for road roller wheels, which can effectively solve the problems in the background art.

[0009] Preferably, the maintenance mechanism includes a threaded rod movably mounted on a fixed frame and a positioning plate. A third synchronous pulley is fixedly mounted on the outer side of the threaded rod near the fixed frame. A second synchronous belt is movably sleeved on the inner side of the third synchronous pulley and the second synchronous pulley. A gear plate is fixedly mounted on the outer side of the threaded rod near the inner side of the fixed frame. T-shaped limiting rings are movably mounted in the inner walls of both sides of the fixed frame. A second bevel gear is fixedly mounted at one end of each of the two sets of T-shaped limiting rings. A gear ring is fixedly mounted at one end of each of the two sets of second bevel gears. A limiting groove ring is fixedly mounted on the outer side of the threaded rod near the other side. A fixed shell is fixedly mounted on the upper end of the positioning plate. A positioning element is movably mounted on the inner side of the fixed shell. A first spring is fixedly mounted between the positioning element and the rear inner wall of the fixed shell. A fixing plate is fixedly mounted at the rear end of the fixed frame. A round rod is fixedly mounted between the two sets of support plates and on the inner side of the fixing plate.

[0010] Preferably, positioning rings are movably arranged on both sides of the outer surface of the round rod, and second bolts are movably arranged on the upper inner side of each positioning ring. A second spring is fixedly arranged at one end of each of the two sets of second bolts. Movable parts are movably arranged on the outer surface of the threaded rod and the round rod, and a grinding part is fixedly installed on the lower side of the movable parts.

[0011] Preferably, the threaded rod moves through the interior of the fixed frame, the two sides of the toothed disc are adapted to the two sets of toothed rings, the two sets of T-shaped limiting rings, the second bevel gears and the toothed rings are mirror symmetrical, the two sets of second bevel gears are respectively meshed with the first bevel gears, the inner side of the limiting groove ring has two limiting grooves, the positioning member passes through the front side of the fixed shell, and the positioning member is stuck in one set of limiting grooves of the limiting groove ring.

[0012] Preferably, the second bolt and the positioning ring are threaded together, the bottom of the second bolt rests on the surface of the round rod, one end of each of the two sets of second springs is fixedly provided with a round plate, the movable part is threaded together with the threaded rod, and the movable part is connected to the grinding part by bolts.

[0013] Preferably, limit strips are fixedly provided at the upper end of the groove near both sides, and several sets of slots are opened inside the groove near the front and rear sides of the groove. Rollers are movably arranged on the outer side of the several sets of slots, and a rolling wheel is provided in the groove of the groove.

[0014] Preferably, the upper ends of several sets of rollers protrude from the upper side of the groove, and the grinding wheel is placed on the upper end of several sets of rollers.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The grinding wheel is pushed into the groove of the slot seat and placed on several sets of rollers. The grinding wheel is rotated by the setting of the groove and the set of several sets of rollers, in conjunction with the drive switching mechanism. Two sets of limit strips are set on both sides of the grinding wheel to prevent the grinding wheel from shifting to the side when rotating.

[0017] The motor drives the rotating shaft and the first bevel gear to rotate, which in turn drives two sets of meshing second bevel gears to rotate in opposite directions. One set of second bevel gears meshes with a gear disc fixed to the outside of the threaded rod through a gear ring, thereby driving the threaded rod to rotate. This causes the threaded movable part and the grinding part to slide to one side along the rod. When it moves to the edge of the rod, it first contacts the second spring, while the positioning part presses against a set of grooves in the limiting groove ring fixed to one side of the threaded rod. This causes the movable part to compress the second spring as it moves, until the pressure of the compressed second spring exceeds the elasticity of the first spring supported behind the positioning part, at which point the threaded rod is compressed. The second spring pushes in the opposite direction, and the positioning part is pushed back by the limiting groove ring. The toothed disc is pushed to mesh with another set of toothed rings and the second bevel gear. At the same time, the positioning part is pushed by the first spring and stuck in another set of grooves, restricting the position of the threaded rod. The threaded rod will be driven to rotate in the opposite direction by another set of rotating toothed rings and the second bevel gear, so that the threaded moving part and the grinding part move back along the round rod. Similarly, it hits the second spring on the other side, realizing the back-and-forth movement of the grinding part. This, together with the drive switching mechanism, rotates the grinding wheel, which can grind, thin, and maintain the surface of the grinding wheel, such as rust or small dents.

[0018] By rotating the first bolt on the ring away from the disc, it is inserted into the corresponding groove, fixing the first synchronous wheel and the movable rod together. The first bolt on the other side is rotated and removed. The motor drives the rotating shaft and a set of connected first synchronous wheels to rotate. At the same time, the sleeved first synchronous belt drives the lower first synchronous wheel, the movable rod, the disc, the extrusion ring, and the outer shell to rotate. Through the use of the fitted outer shell and several sets of rollers on the lower side, the grinding wheel is rotated and the maintenance mechanism performs comprehensive grinding, which is convenient for surface grinding and repair processing of large areas and the entire grinding wheel that is rusted.

[0019] By screwing in one set of first bolts near the disc and removing the other set of first bolts, the second synchronous wheel and the movable rod are fixed together. The rotating threaded rod drives the sleeved second synchronous wheel and the movable rod fixed to the second synchronous wheel to rotate through the third synchronous wheel and the second synchronous belt. The threaded rod rotates back and forth during operation, thereby driving the grinding wheel to reciprocate. In conjunction with loosening the two sets of second bolts, the two sets of second springs are moved to both sides of the location where some weld cracks need to be ground separately. "Simultaneously, the movable part and the grinding part move to the welding position." Thus, the threaded rod drives the outer shell to reciprocate the grinding wheel, and the grinding part will locally grind the area back and forth to make the welding position match the surface of the grinding wheel. By switching, different processing methods can be achieved, replacing manual handling and improving practicality. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0031] Please see Figure 1-8 An embodiment of the present invention provides a grinding and processing device for road roller wheels, comprising a groove seat 1, with support plates 2 fixedly disposed at both ends of the groove seat 1, two sets of fixing plates 3 fixedly disposed at one end of one set of support plates 2, a fixing frame 4 fixedly disposed at one end of the two sets of fixing plates 3, a positioning plate 5 fixedly disposed at one end of the other set of support plates 2, a drive switching mechanism 6 disposed on the front side of the fixing frame 4, and a maintenance mechanism 7 disposed between the two sets of support plates 2. The drive switching mechanism 6 includes a U-shaped frame 61 fixedly disposed at the front end of the fixing frame 4, a motor 62 fixedly mounted at the front end of the U-shaped frame 61, a rotating shaft 63 fixedly disposed at the rear end of the motor 62, and a first bevel gear 64 fixedly disposed at the rear end of the rotating shaft 63. A movable rod 65 is movably mounted on the lower side. A first synchronous pulley 66 is fixedly mounted on the outside of both the rotating shaft 63 and the movable rod 65. A first synchronous belt 67 is movably sleeved on the inner side of the two sets of first synchronous pulleys 66. A second synchronous pulley 68 is movably sleeved on the outer side of the movable rod 65 near the U-shaped frame 61. A ring 69 is fixedly mounted on one end of the second synchronous pulley 68 and one set of first synchronous pulleys 66 on the lower side. A first bolt 610 is movably mounted on the inner side of both sets of rings 69. A circular groove 611 is opened on the inner side of the movable rod 65 corresponding to the positions of the two sets of first bolts 610. A disc 612 is fixedly mounted on the outer side of one side of the movable rod 65. A compression ring 613 is fixedly mounted on the outer side of the disc 612. A housing 614 is fixedly mounted on the outer side of the compression ring 613.

[0032] The rotating shaft 63 moves through one side of the U-shaped frame 61 and the fixed frame 4. Limiting plates are provided on the outer side of the movable rod 65 near the second synchronous wheel 68, the lower set of first synchronous wheels 66, and the end of the ring 69. The first bolt 610 is threadedly connected to the ring 69. The first bolt 610 is adapted to the circular groove 611. The extrusion ring 613 and the outer shell 614 are made of rubber. Anti-slip strips are provided on the outer side of the outer shell 614.

[0033] The motor 62 drives the rotating shaft 63 and the first bevel gear 64 to rotate, which in turn drives the two sets of meshing second bevel gears 76 to rotate in opposite directions. One set of second bevel gears 76 meshes with the toothed disc 74 fixed to the outside of the threaded rod 71 through the toothed ring 77, thereby driving the threaded rod 71 to rotate. This causes the threaded movable part 717 and the grinding part 718 to slide to one side along the round rod 713. When moving to the edge position, it first contacts the second spring 716, while the positioning part 710 presses against a set of grooves in the limiting groove ring 78 fixed to one side of the threaded rod 71. This causes the movable part 717 to compress the second spring 716 when it moves, until the pressure of the compressed second spring 716 is greater than the elasticity of the first spring 711 supported behind the positioning part 710, at which point the threaded rod 71 is stopped. The compressed second spring 716 pushes in the opposite direction, and the positioning part 710 is pushed back by the limiting groove ring 78. The toothed disc 74 is pushed to mesh with another set of toothed rings 77 and the second bevel gear 76. At the same time, the positioning part 710 is pushed and stuck in another set of grooves by the first spring 711, which restricts the position of the threaded rod 71. The threaded rod 71 will be driven to rotate in the opposite direction by another set of rotating toothed rings 77 and the second bevel gear 76, so that the threaded movable part 717 and the grinding part 718 move back along the round rod 713. Similarly, it hits the second spring 716 on the other side, realizing the back-and-forth movement of the grinding part 718. This, in conjunction with the drive switching mechanism 6, rotates the grinding wheel 11, which can grind, thin, and maintain the surface of the grinding wheel 11, such as rust or small dents.

[0034] The maintenance mechanism 7 includes a threaded rod 71 movably mounted on the fixed frame 4 and the positioning plate 5. A third synchronous pulley 72 is fixedly mounted on the outside of the threaded rod 71 near the fixed frame 4. A second synchronous belt 73 is movably sleeved on the inner side of the third synchronous pulley 72 and the second synchronous pulley 68. A geared disc 74 is fixedly mounted on the outside of the threaded rod 71 near the inner side of the fixed frame 4. T-shaped limiting rings 75 are movably mounted in the inner walls of both sides of the fixed frame 4. A second bevel gear 76 is fixedly mounted at one end of each of the two sets of T-shaped limiting rings 75. A gear ring 77 is fixedly mounted at one end of each of the two sets of second bevel gears 76. A limiting groove ring 78 is fixedly mounted on the outside of the threaded rod 71 near the other side. A second synchronous belt 74 is fixedly mounted on the upper end of the positioning plate 5. A fixed shell 79 is provided with a positioning element 710 movably disposed on the inner side of the fixed shell 79. A first spring 711 is fixedly disposed between the positioning element 710 and the rear inner wall of the fixed shell 79. A fixing plate 712 is fixedly disposed at the rear end of the fixed frame 4. A round rod 713 is fixedly disposed between the two sets of support plates 2 and the inner side of the fixing plate 712. A positioning ring 714 is movably disposed on both sides of the outer side of the round rod 713. A second bolt 715 is movably disposed on the upper inner side of the positioning ring 714. A second spring 716 is fixedly disposed at one end of each of the two sets of second bolts 715. A movable part 717 is movably disposed on the outer side of the threaded rod 71 and the round rod 713. A grinding part 718 is fixedly installed on the lower side of the movable part 717.

[0035] The threaded rod 71 moves through the interior of the fixed frame 4. The two sides of the toothed disc 74 are adapted to the two sets of toothed rings 77. The two sets of T-shaped limiting rings 75, the second bevel gears 76, and the toothed rings 77 are mirror symmetrical. The two sets of second bevel gears 76 are respectively meshed with the first bevel gears 64. Two limiting grooves are opened on the inner side of the limiting groove ring 78. The positioning member 710 passes through the front of the fixed shell 79 and is stuck in one of the limiting grooves of the limiting groove ring 78. The second bolt 715 is threadedly connected to the positioning ring 714. The bottom of the second bolt 715 abuts against the surface of the round rod 713. One end of each of the two sets of second springs 716 is fixedly provided with a round piece. The movable member 717 is threadedly connected to the threaded rod 71. The movable member 717 is connected to the grinding member 718 by bolts.

[0036] By rotating the first bolt 610 on the ring 69 on the side away from the disc 612, it is inserted into the corresponding groove 611, fixing the first synchronous wheel 66 and the movable rod 65 together. The first bolt 610 on the other side is rotated and removed. The motor 62 drives the rotating shaft 63 and the connected set of first synchronous wheels 66 to rotate. At the same time, the sleeved first synchronous belt 67 drives the lower first synchronous wheel 66, the movable rod 65, the disc 612, the extrusion ring 613, and the outer shell 614 to rotate. Through the use of the fitted outer shell 614 and several sets of rollers 10 on the lower side, the grinding wheel 11 is rotated and the maintenance mechanism 7 performs comprehensive grinding. This facilitates the surface grinding and repair of large and comprehensive rusted grinding wheels 11. On the other hand, by screwing in one set of first bolts 610 near the disc 612, the other set of first bolts 610 is removed. The second synchronous wheel 68 is fixedly installed with the movable rod 65. The rotating threaded rod 71 drives the sleeved second synchronous wheel 68 and the movable rod 65 fixed to the second synchronous wheel 68 to rotate through the third synchronous wheel 72 and the second synchronous belt 73. The threaded rod 71 rotates back and forth during operation, thereby driving the grinding wheel 11 to reciprocate. In conjunction with loosening the two sets of second bolts 715, the two sets of second springs 716 are moved to both sides of the position where some weld cracks need to be ground separately. "At the same time, the movable part 717 and the grinding part 718 move to the welding position." Thus, the threaded rod 71 drives the outer shell 614 to reciprocate the grinding wheel 11, while the grinding part 718 will perform local back and forth grinding on the area to make the welding position match the surface of the grinding wheel 11. By switching, different processing methods can be achieved, replacing manual handling and improving practicality.

[0037] Limiting strips 8 are fixedly installed at the upper end of the groove 1 near both sides. Several sets of slots 9 are opened inside the groove 1 near the front and rear sides of the groove. Rollers 10 are movably installed on the outer side of the several sets of slots 9. A grinding wheel 11 is installed in the groove of the groove 1. The upper ends of the several sets of rollers 10 protrude from the upper side of the slots 9. The grinding wheel 11 is placed on the upper end of the several sets of rollers 10.

[0038] The grinding wheel 11 is pushed into the groove of the slot seat 1 and placed on several sets of rollers 10. The grinding wheel 11 is rotated by the setting of the groove position and the several sets of rollers 10 in conjunction with the drive switching mechanism 6. Two sets of limit strips 8 are set on both sides of the grinding wheel 11 to prevent the grinding wheel 11 from shifting laterally when rotating.

[0039] Working principle:

[0040] In use, the grinding wheel 11 is first pushed into the groove of the slot seat 1 and placed on several sets of rollers 10. The grinding wheel 11 is rotated by the groove position and the arrangement of the rollers 10, in conjunction with the drive switching mechanism 6. Two sets of limiting strips 8 are set on both sides of the grinding wheel 11 to prevent lateral displacement during rotation. Next, the motor 62 drives the rotating shaft 63 and the first bevel gear 64 to rotate, causing the two sets of meshing second bevel gears 76 to rotate in opposite directions. One set of second bevel gears 76 meshes with the toothed disc 74 fixed externally to the threaded rod 71 through the toothed ring 77, thereby driving the threaded rod 71 to rotate. This causes the threaded movable part 717 and the grinding part 718 to slide to one side along the round rod 713. When moving to one edge position, it first engages with the second... Spring 716 contacts the positioning element 710, which rests against a set of grooves in the limiting ring 78 fixed on one side of the threaded rod 71. This causes the moving part 717 to compress the second spring 716 as it moves. The compression of the second spring 716 continues until its pressure exceeds the elasticity of the first spring 711 supporting the rear of the positioning element 710. At this point, the threaded rod 71 is pushed in the opposite direction by the compressed second spring 716, and the positioning element 710 is pushed back by the limiting ring 78. The gear disc 74 is pushed to mesh with another set of gear rings 77 and the second bevel gear 76. Simultaneously, the positioning element 710 is pushed and locked in another set of grooves by the first spring 711, restricting the position of the threaded rod 71. The threaded rod 71 is then driven to rotate in the opposite direction by the rotating gear rings 77 and the second bevel gear 76, causing the threaded moving part 717 to... 7. The grinding part 718 moves back along the round rod 713, and similarly impacts the second spring 716 on the other side, realizing the back-and-forth movement of the grinding part 718. This, in conjunction with the drive switching mechanism 6, rotates the grinding wheel 11, which can grind, thin, and maintain small problems such as rust or small dents on the surface of the grinding wheel 11. Finally, by rotating the first bolt 610 on the ring 69 away from the disc 612, it is inserted into the corresponding round groove 611, so that the first synchronous wheel 66 and the movable rod 65 are fixed together. The first bolt 610 on the other side is rotated and removed. The motor 62 drives the rotating shaft 63 and the connected set of first synchronous wheels 66 to rotate. At the same time, the sleeved first synchronous belt 67 drives the lower first synchronous wheel 66 and the movable rod 65 to rotate. The disc 612, extrusion ring 613, and outer shell 614 rotate. Through the use of the fitted outer shell 614 and several sets of rollers 10 on the lower side, the grinding wheel 11 rotates in conjunction with the maintenance mechanism 7 for comprehensive grinding. This facilitates surface grinding and repair of large and widespread rusted grinding wheels 11. On the other hand, by screwing in one set of first bolts 610 near the disc 612 and removing another set of first bolts 610, the second synchronous wheel 68 and the movable rod 65 are fixed together. The rotating threaded rod 71 drives the sleeved second synchronous wheel 68 and the movable rod 65 fixed to the second synchronous wheel 68 to rotate via the third synchronous wheel 72 and the second synchronous belt 73. The threaded rod 71 rotates reciprocally during operation, thereby driving the grinding wheel 11 to reciprocate.By loosening the two sets of second bolts 715 and moving the two sets of second springs 716 to both sides of the areas requiring separate grinding after welding cracks, "simultaneously, the movable part 717 and the grinding part 718 move to the welding position." This causes the threaded rod 71 to drive the outer casing 614 to reciprocate over the grinding wheel 11, while the grinding part 718 performs localized back-and-forth grinding on that area, adapting the welding position to the surface of the grinding wheel 11. By switching between different processing methods, this replaces manual handling and improves practicality.
