the bracket 141 includes a central bar 1411 and two rotating bars 1412 at two ends, the rotating bars 1412 are fixedly connected with the bar 1411 through connecting bars 1413, the rotating assembly 142 includes a supporting seat 1421 and a flat mounting ring 1422, the rotating bars 1412 pass through the supporting seat 1421 and are in rotating fit with the supporting seat 1421, and the supporting seat 1421 is provided with a rotating seat 1423 rotating synchronously with the rotating bars 1412;
the rotating levers 1412 are symmetrically fixed with rotating platforms 1415 perpendicular to the axial direction of the rotating levers 1412 on both sides of the supporting seat 1421, driving rods 1414 parallel to the rotating levers 1412 and having the same diameter are fixed on the rotating platforms 1415, one flat mounting ring 1422 is sleeved on the rotating levers 1412 and the driving rods 1414 on the side surface of the same rotating platform 1415, the flat mounting rings 1422 on both sides of the supporting seat 1421 are driven by a lifter 1424 fixed on the rotating seat 1423 to synchronously lift, and connecting columns 1425 for fixing the tamping rod handles 600 are mounted on the side surfaces of the flat mounting rings 1422.
Based on the tamping bar fixing frame 120 with the above structure, when the bracket 141 rotates around the rotation lever 1412, the rotation platform 1415 and the driving rod 1414 rotate synchronously with the rotation lever 1412, and the driving rod 1414 rotates in a circular arc around the center of the rotation lever 1412, so that the flat mounting ring 1422 deflects by a certain angle, thereby changing the angles of the connecting post 1425 and the tamping bar handle 600.
In some embodiments, the drive shaft 422 of the female clutch 420 is driven by a pulley 427 mounted thereon, and the motor 112 rotates the pulley 427 via the transmission 113. The transmission 113 is mounted on the equipment mounting frame 110, and the motor 112 synchronously provides power to the transmission shafts 422 of the four inner hole splitters 420 through the transmission 113 so as to synchronously perform multi-point tamping operations.
More specifically, in order to conveniently adjust the working angle of the tamper bar handle 600 at any time, the movable push handle 130 includes a manipulation push handle 131, a traversing push rod 132 fixed to the frame 100, and an angle adjusting assembly 133, wherein,
the angle adjusting assembly 133 comprises an adjusting seat 1331 arranged on the frame 100 and a rotating shaft 1332 assembled on the adjusting seat 1331, the front end of the operating pushing hand 131 is fixed on the rotating shaft 1332 so that the operating pushing hand 131 can swing relative to the adjusting seat 1331, and the transverse moving pushing rod 132 is used for pushing the adjusting seat 1331 to transversely move on the frame 100;
the manipulating pushing handle 131 is provided with a bar-shaped chute 1311, and is provided with a connecting seat 1312 capable of sliding along the bar-shaped chute 1311, wherein the connecting seat 1312 is used for connecting the cross bar 1411 of the bracket 141 in a shape like a Chinese character 'ji' through a ball shaft, so that the cross bar 1411 can be synchronously driven to swing when the manipulating pushing handle 131 swings.
Therefore, when the tamping angle needs to be adjusted, only the constructor swings the operating pushing hand 131 to use the rotation shaft 1332 as a rotation pivot point to rapidly pry the transverse bar 1411 of the bracket 141 according to the lever principle, and it should be noted that the bracket 141 can also be designed such that the length of the connecting bar 1413 is far longer than the distance between the rotation bar 1412 and the driving bar 1414, and then forms a lever again to push the flat mounting ring 1422 to change the angle. Therefore, the operation intensity of constructors is greatly reduced, and the manual operation is very simple.
After the angle is adjusted in place, a period of time is needed to be tamping at the adjusted angle to enable the ballast of the ballast bed to flow under the sleeper to be compact, in some embodiments, a stabilizing structure for keeping the posture after the angle adjustment is also designed, a plurality of adjusting grooves 1333 are formed in the adjusting seat 1331, a sliding frame 134 is further arranged on the operating pushing hand 131, one end of the sliding frame 134 is used for being clamped into the adjusting groove 1333 so as to keep the operating pushing hand 131 and the connecting seat 1312 in a locking state without relative rotation, and a pressure spring 135 for propping against the sliding frame 134 is arranged between the other end of the sliding frame 134 and the operating pushing hand 131. The constructor can freely adjust the swing position of the operating pushing hand 131 by pulling the sliding frame 134 to enable the sliding frame 134 to be in non-contact with the adjusting groove 1333, when the sliding frame 134 is swung in place, the constructor only needs to loosen the sliding frame, under the action of the pressure spring 135, the front end of the sliding frame is embedded into the adjusting groove 1333, the operating pushing hand 131 is kept to be locked with the connecting seat 1312, the tamping can be stably performed for a period of time, and after the tamping is completed, the constructor can adjust the angle again.
In order to ensure the full coverage of the ballast bed by the tamping point of the device, the frame 100 is provided with a rail platform 150 for the support seat 1421 to slide transversely. When the tamping position needs to be laterally adjusted, only the transverse pushing rod 132 needs to be driven to push the adjusting seat 1331, and when the adjusting seat 1331 is transversely moved, the bracket 141 and the operating pushing hand 131 can synchronously move in the transverse direction, so that the whole transverse movement of the tamping rod fixing frame 120 is facilitated, and the rail platform 150 can conveniently slide the supporting seat 1421. The traversing push rod 132 can be in the form of an electric push rod or a hydraulic cylinder or an air cylinder, and a driving switch thereof can be arranged on the operating push rod 131 through a circuit so as to be convenient for constructors to operate at any time.
Meanwhile, the lifter 1424 can also adopt the form of an electric push rod or a hydraulic cylinder or an air cylinder, a driving switch of the lifter 1424 can also be arranged on the operating push handle 131 through a circuit so as to be convenient for constructors to operate at any time, and the height of the flat mounting ring 1422 can be changed through the lifter 1424 so as to further change the tamping depth of the vibrating rod assembly 200, thereby being beneficial to compacting the railway ballast flowing under the sleeper.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
