Example 1.1 as shown in fig. 1, a tamping apparatus including a swash plate joint includes a vibration exciting device 1, an opening and closing driving device 2, and a clamping device 3, and for convenience of illustration, a coordinate system is defined as shown in the figure, wherein the coordinate system includes X, Y, Z three-dimensional directions, wherein X is a direction in which a steel rail extends, Y is a direction parallel to a sleeper, and Z is a vertical direction.
The excitation device 1 comprises a rotary power 11, a swash plate 12 and a vibrating rod 13. The rotating power 11 drives the swash plate 12 to rotate, and one end of the vibrating rod 13 passes through the through hole on the bracket 41 and is hinged with the swash plate 12. The rotary power 11 comprises two outputs, each of which is connected to a swash plate 12. The swash plate 12 includes two plates parallel to each other and capable of rotating relatively, and the end faces of the plates are not perpendicular to the rotation axis and form a certain angle, such as an obtuse angle or an acute angle. The center of one of the discs is connected with the output end of the rotary power 11, and the center of the other disc is hinged with a bracket 41 fixedly arranged on the fixed frame 4.
The vibrating rod 13 passes through a bracket 41 of the fixed frame 4, one end of the vibrating rod is hinged with the swash plate 12, and the other end of the vibrating rod is hinged with the opening and closing driving device 2. As the swash plate 12 rotates, the vibration rod 13 reciprocates.
The vibrating rod 13 is hinged between the second joint 122 and the first joint 5 of the swash plate 12, and the support 41 on the fixed frame 4 is hinged with the first joint 121 of the swash plate 12, wherein the first joint 12 is the central point of the other body of the swash plate.
The swash plate structure has the advantages that: the rotary motion of the rotary power is simply converted into the reciprocating motion of the vibrating rod, the double-pillow tamping device is easily derived, and only a hinge point needs to be led out from the end part of the swash plate, and then the vibrating rod, the opening and closing driving device and the clamping device are correspondingly arranged.
The two ends of the opening and closing driving device 2 can be extended and retracted, and oil cylinder driving is preferred. One end of the opening and closing driving device 2 is hinged with the vibrating rod 13 through a first joint 5, and the other end of the opening and closing driving device is hinged with the clamping device 3 through a second joint 6.
The clamping device 3 comprises a clamping arm 31 and a clamping pick 32, and the clamping pick 32 is fixedly installed at the lower end of the clamping arm 31. The gripping arm 31 is articulated to the fixed frame 4 by means of the joint three 7. The third joint 7 is preferably arranged in the middle of the holding arm 31.

a tamping device with a swash plate joint is arranged on a lower inserting frame 8, and the tamping device with the swash plate joint can move up and down along the lower inserting frame 8 to perform lower inserting and lifting actions. The swash plate 12 is rotated by the rotating power 11, so that the vibrating rod 13 reciprocates, i.e. generates vibration, and the vibration is transmitted to the end of the clamping pick 32 in turn. The opening and closing driving device 2 can do telescopic motion, then the clamping arm 31 is driven to rotate around the joint III 7, and then the clamping pick 32 is driven to do clamping and opening actions.
When the tamping device is operated, the tamping device descends along the lower inserting frame 8, the clamping pickaxe 32 is inserted into the ballast 10 of the track bed at the lower part of the sleeper 9, the clamping pickaxe 32 is inserted along with high-frequency vibration, the lower inserting of the clamping pickaxe 32 is facilitated, the opening and closing driving device 2 stretches out after the insertion, the clamping pickaxe 32 is pushed to perform clamping action, and the high-frequency vibration is still accompanied at the moment, so that the flowing of the ballast 10 is facilitated. After the clamping action is completed, the tamping device is lifted, the opening and closing driving device 2 is retracted, and the clamping pick 32 is opened. This completes a tamping action.
According to the vibration accompanying conditions under different actions, the embodiment proposes two vibration modes: the vibration excitation device 1 vibrates in the whole working process; the vibration excitation device 1 vibrates in the whole process that the clamping pick 32 contacts the ballast 10 of the ballast bed, and does not vibrate in other processes.
Example 1.2 a tamping apparatus including a swash plate joint, the difference from example 1.1 is that: the holding pick 32 is detachably connected to the holding arm 31.
