Referring to fig. 1-7, an exemplary embodiment of a rubbing device according to the invention is shown. As shown in fig. 1 and 2, the flattening device comprises a bearing frame, a flattening beam 1, an elevation angle adjusting sub-device and a driving mechanism 2.
The bearing frame is used for supporting the rest structures of the rubbing device, is generally 冂 -shaped and comprises a main beam 3 and two side beams 4 fixed with two ends of the main beam 3. Specifically, the main beams 3 and the side beams 4 are formed by splicing a plurality of square pipes, and adjacent square pipes are connected through flanges, bolts and the like; therefore, the lengths of the main beam 3 and the side beam 4 can be adjusted to increase or decrease the number of square tubes according to actual needs. It should be understood that the main beams 3, side beams 4 may also be integrally formed, or other suitable structures, not specifically illustrated herein.
The rubbing beam 1 is hung below the side beam 4 by a suspension arm 5 connected with the side beam 4, and the driving mechanism 2 can move along the rubbing working direction relative to the side beam 4 when working. The working direction of the rubbing, i.e. the direction in which the rubbing beam 1 moves relative to the carrier, i.e. the direction substantially perpendicular to the advancing direction of the paver.
Specifically, the rubbing beam 1 comprises a rubbing beam main body 6, wherein the rubbing beam main body 6 is formed by splicing a plurality of square pipes, and adjacent square pipes are connected through flanges, bolts and the like. Thus, as well, the body 6 of the flat-rubbing beam can adjust the length of the flat-rubbing beam 1 in a manner of increasing or decreasing the number of square tubes according to actual needs. It should be appreciated that the body 6 may also be formed as a single piece, or any other suitable structure, not shown.
The rubbing flat beam 1 further comprises a rubbing flat plate 7, wherein the rubbing flat plate 7 is fixed at the bottom of the rubbing flat beam main body 6, and directly acts on a cement pavement during rubbing flat work so as to realize slurry lifting and pavement repairing.
Referring now to fig. 4 and 7, the boom 5 includes a hanger bracket 8, a height adjuster 9, a first fastener 10, and a bushing 11. The hanger 8 is cylindrical, is inserted into the side member 4, and is fixed by welding. The height adjusting piece 9 is a rod piece arranged vertically, is inserted into a vertical through hole of the hanging seat 8, and can move in a vertical direction and lock a position relative to the hanging seat 8 under the action of the first fastening piece 10. The sleeve 11 forms a horizontal through hole and is fixedly connected with the lower protruding end of the height adjusting piece 9 through a flange and bolts.
The upper surface of the rubbing girder 1 is also provided with a sliding seat 12, and the sliding seat 12 is welded and fixed with the rubbing girder 1. The sliding shaft 13 of the sliding seat 12 is inserted into the horizontal through hole of the shaft sleeve member 11, and can move along the rubbing working direction relative to the shaft sleeve member 11. Of course, the sliding shaft 13 can also rotate relative to the sleeve member 11, i.e. the flattening beam 1 can also rotate relative to the sleeve member 11.
Specifically, the outer peripheral wall of the upper protruding end of the height adjusting member 9 forms an external thread, and the first fastening member 10 is a fastening nut, and the inner peripheral wall thereof forms an internal thread that mates with the external thread. When the first fastening member 10 is rotated, the height adjusting member 9 can drive the leveling beam 1 to move to a set height. For example, when the first fastening member 10 is rotated clockwise, the height adjusting member 9 moves upwards under the promotion of the first fastening member 10 and drives the flat-twisting beam 1 to move upwards at the same time, after the flat-twisting beam 1 moves upwards to a set height, the rotation of the first fastening member 10 is stopped, the first fastening member 10 abuts against the hanging seat 8 and/or the upper end surface of the side beam 4, and the height of the flat-twisting beam 1 is locked; when the first fastening member 10 is rotated counterclockwise, the height adjusting member 9 moves downward synchronously with the flat beam 1 under the action of gravity of the flat beam 1, after the flat beam 1 moves downward to a set height, the rotation of the first fastening member 10 is stopped, the first fastening member 10 abuts against the upper end surface of the hanging seat 8 and/or the side beam 4, the height adjusting member 9 and the flat beam 1 stop moving downward, and the height of the flat beam 1 is locked.
Preferably, a linear bearing is disposed in the vertical through hole of the hanging seat 8, and the height adjusting member 9 is sleeved in the linear bearing, so as to reduce friction between the height adjusting member 9 and the hanging seat 8. A linear bearing is arranged in the horizontal through hole of the shaft sleeve piece 11, and the sliding shaft 13 of the sliding seat 12 is sleeved in the linear bearing so as to reduce friction between the sliding shaft 13 and the shaft sleeve piece 11.
Referring now to fig. 1 and 5, the elevation adjustment sub-assembly includes a first elevation adjustment sub-assembly 14 secured to the main beam 3, and two second elevation adjustment sub-assemblies 15 secured to the two side beams 4, respectively. The two second elevation angle adjusting sub-devices 15 are respectively located at two sides of the first elevation angle adjusting sub-device 14, and the first elevation angle adjusting sub-device 14 and the second elevation angle adjusting sub-device 15 are used for jointly adjusting and locking the elevation angle of the flat-twisting beam 1.
As shown in fig. 6, the first elevation adjustment sub-apparatus 14 includes a first link 16, a main roller 17, and an extension adjustment mechanism. The first connecting piece 16 is a rod piece which is vertically arranged, and the upper end of the first connecting piece is fixedly welded with the bottom of the main beam 3. The main roller 17 can prop against the rubbing girder 1 and roll along with the movement of the rubbing girder 1 in the rubbing direction. The extension adjusting mechanism is welded and fixed to the lower end of the first connecting piece 16, and is used for adjusting and locking the extension distance of the main roller 17.
The extension adjustment mechanism comprises a barrel 8, an extension adjustment member 19, and a second fastener 20. The cylinder 8 is horizontally arranged in a direction perpendicular to the flat beam 1 and is welded to the lower end of the first connecting member 16. The extension adjusting member 19 is a strip rod member, and is inserted in a horizontal through hole of the cylinder 8 and can move in a horizontal direction relative to the cylinder 8, and the main roller 17 is mounted at an extension end of the extension adjusting member 19 toward the flattening beam 1 through a U-shaped wheel frame 21. The second fastening member 20 is used for adjusting and locking the relative positions of the cylinder 8 and the extension adjusting member 19, and since the main roller 17 is mounted on the extension end of the extension adjusting member 19 facing the flatwise beam 1, the second fastening member 20 adjusts and locks the position of the extension adjusting member 19 relative to the cylinder 8, i.e. the extension distance of the main roller 17 can be adjusted and locked.
Specifically, the outer peripheral walls of the two protruding ends of the protruding adjusting member 19 form external threads, and the second fastening member 20 is a fastening nut, and the inner peripheral wall thereof forms internal threads that mate with the external threads. When the second fastening members 20 at the two protruding ends of the protruding adjusting member 19 are rotated, the protruding adjusting member 19 can drive the main roller 17 to move to a set position. For example, when the second fastening members 20 located at the two protruding ends of the protruding adjusting member 19 are rotated clockwise, the protruding adjusting member 19 moves horizontally to the side of the rubbing beam 1, and drives the main roller 17 to move horizontally to the side of the rubbing beam 1, and after the main roller 17 moves to a set protruding distance, the second fastening members 20 stop rotating, and the protruding distance of the main roller 17 is locked; when the second fastening members 20 at the two protruding ends of the protruding adjusting member 19 are rotated counterclockwise, the protruding adjusting member 19 moves horizontally to a side far away from the flat beam 1, and drives the main roller 17 to move horizontally to a side far away from the flat beam 1, and after the main roller 17 moves to a set protruding distance, the rotation of the second fastening members 20 is stopped, and the protruding distance of the main roller 17 is locked.
As shown in fig. 7, the second elevation adjustment sub-assembly 15 includes a second connection member 22, a movable member 23, a locking member 24, and an auxiliary roller 25. The upper part of the second connecting piece 22 is welded and fixed with the side member 4. The fixed end of the movable piece 23 above is hinged with the second connecting piece 22. The locking member 24 is used to adjust and lock the angle between the second connecting member 22 and the movable member 23. The auxiliary roller 25 is mounted at the movable end of the movable member 23 below, and can support against the leveling beam 1 together with the main roller 17 and roll along with the movement of the leveling beam 1 in the leveling direction.
Specifically, the second connecting member 22 forms a limiting wall 26 disposed opposite to the movable member 23 on the side where the movable member 23 is located, for preventing the movable member 23 from moving in the rubbing direction. The locking member 24 is a fastening bolt, and is inserted into a screw hole of the second connecting member 22 and can be abutted against the movable member 23, and when the locking member 24 is rotated, the locking member 24 can cause the movable member 23 to rotate to a set angle, so as to cause the auxiliary roller 25 to move to a set position. For example, the locking member 24 is rotated clockwise, the locking member 24 drives the movable member 23 to rotate anticlockwise, and simultaneously drives the auxiliary roller 25 to move, after the movable member 23 rotates to a set angle, the rotation of the locking member 24 is stopped, and the included angle between the second connecting member 22 and the movable member 23 is locked; and the locking piece 24 is rotated anticlockwise, the movable piece 23 is rotated clockwise under the action of gravity of the rubbing beam 1, after the movable piece 23 is rotated to a set angle, the rotation of the locking piece 24 is stopped, and the included angle between the second connecting piece 22 and the movable piece 23 is locked.
The locking member 24 and the second fastening member 20 are rotated to enable the main roller 17 and the auxiliary roller 25 to move to the set positions and then to lock, and the main roller 17 and the auxiliary roller 25 are propped against the flat-twisting beam 1, so that the flat-twisting beam 1 can be driven to rotate relative to the shaft sleeve 11 during the movement of the main roller 17 and the auxiliary roller 25, thereby realizing the adjustment and locking of the elevation angle of the flat-twisting beam 1.
Considering that the first elevation angle adjusting sub-means 14 receives the main pressure from the flatback girder 1 and the installation space of the auxiliary roller 25 when adjusting and locking the elevation angle of the flatback girder 1, in this embodiment, the main roller 17 is a rubber roller which is wear-resistant and easy to replace, and the auxiliary roller 25 is a rolling bearing which is small in size and long in service life.
Referring to fig. 2 and 3, the driving mechanism 2 includes a power sub-device fixed on the rubbing beam 1, an eccentric wheel 27 fixed on the output end of the power sub-device, and a swing arm 28 sleeved on the eccentric wheel 27. The swing arm 28 is hinged to a fixed arm 29 fixed to the side member 4. When the driving mechanism 2 works, the rubbing beam 1 can be driven to reciprocate along the rubbing working direction.
In this embodiment, the power sub-device is composed of a hydraulic motor and a reduction gearbox, which are installed in the inner space of the box 30 fixed on the flat beam 1. A self-aligning bearing 31 is arranged in the mounting hole of the swing arm 28, and the eccentric wheel 27 is sleeved in the self-aligning bearing 31 so as to reduce friction between the eccentric wheel 27 and the swing arm 28.
The leveling device can adjust the horizontal height and the elevation angle of the leveling beam 1, effectively adjust the size of the rolled slurry roll, and further improve the paving quality. The rubbing girder 1 adopts a two-point hanging and three-roller propping mode, so that the rubbing girder 1 moves stably during working, and the paving quality is further improved.
