The track lifting and lining device has the defects that the track lifting wheel and the track lifting hook are designed at different positions, and the control and operation of the track lifting wheel and the track lifting hook are mutually independent, so that the track lifting and lining device is not compact in structure and complex in operation. The tamping device has the characteristic of single structural type, and the defect of low working reliability caused by the over-complex structure of part of the tamping devices. Therefore, it is necessary to develop a tamping vehicle suitable for turnout operation, which has the characteristics of simple and compact structure, reliable work, high engineering application value and the like.
For example, chinese patent publication No. CN1056140A discloses a track tamping machine in which the tamping units can traverse. A travelling track tamping machine having four tamping units which are arranged on both sides of a rail and can be displaced transversely along the rail is provided with a tamping mechanism which can be vibrated by opening and closing energy. The tamping units are mounted on a machine carrier bar which is connected to the machine frame and whose height is adjusted along the guide rails, the machine frame of each outer tamping unit in the transverse direction of the machine being mounted on the machine frame of the adjacent inner tamping unit arranged in the transverse direction of the machine, while the machine frame of the outer tamping unit can be moved laterally along the guide rails at a distance from the machine frame of the inner tamping unit by means of a displacement drive, and the two inner tamping units can be moved individually on the transverse guide rails which are horizontal in the transverse direction in the longitudinal direction of the machine. But its operational reliability is low.

Example 2.1 a tamping vehicle suitable for turnout operations, which is the same as the example 1.1, but is different from the structure of the rotary traversing frame shown in figures 7-9. Fig. 8 is a view showing the structure of the inner frame, and fig. 9 is a view showing the structure of the outer frame.
As shown in fig. 7, the rotary traverse frame 9a includes an inner rotary traverse device 91a, an outer rotary traverse device 92a, and a working unit mounting frame 93 a.
The inner rotary traversing device 91a includes an inner rotary device 911a and an inner traversing device 912a for effecting a rotary motion and a traversing motion, respectively. As shown in fig. 8, the inner rotating device 911a includes an inner fixed beam 9111a, an inner rotating beam 9112a, an inner rotating shaft 9113a, an inner fixed frame 9114a, an inner rotating frame 9115a, and an inner rotating drive mechanism 9116 a.

When the inner rotation driving mechanism 9116a acts, the inner rotation beam 9112a drives the inner rotation frame 9115a to rotate around the inner rotation shaft 9113a, so as to realize the rotation action.
The inner-traverse device 912a includes an inner-traverse guide column 9121a, an inner-traverse guide bush 9122a, and an inner-traverse driving mechanism 9123 a. The inner-traverse guide sleeve 9122a is provided with an inner operation unit mounting frame 931a which can slide along the inner-traverse guide post 9121a under the action of an inner-traverse driving mechanism 9123 a. The inner lateral moving guide pillar 9121a is connected to the inner rotating frame 9115a, so that when the inner rotating frame 9115a rotates, the inner lateral moving guide pillar 9121a also rotates, and further drives the inner operation unit mounting frame 931a to rotate. The inner-lateral-movement driving mechanism 9123a has one end connected to the inner operation unit mounting frame 931a and the other end connected to the inner fixed frame 9114 a. When the inner-traverse driving mechanism 9123a acts, the inner operation unit mounting frame 931a is driven to move along the inner-traverse guide post 9121a, and then the transverse-traverse action is realized. In this embodiment, the inner working unit mounting brackets 931a are mounted in two sets for the inner working.
In this embodiment, the inner fixing frame 9114a includes an inner fixing frame guide groove, which is preferably disposed at the edge of the inner fixing frame 9114a, or more preferably, uniformly disposed at the four corners of the edge of the inner fixing frame 9114 a.

When the work unit does not require the remote work, the inner work unit mounting frame 931a and the outer work unit mounting frame 932a are fixedly connected to each other, and the operation is controlled by the inner rotary traverse device 91 a. When the working unit needs to perform remote work, the inner working unit mounting frame 931a and the outer working unit mounting frame 932a are unlocked from each other, the inner working unit mounting frame 931a is controlled to move by the inner rotary traversing device 91a, the outer working unit mounting frame 932a is controlled to move by the outer rotary traversing device 92a, and the inner working unit mounting frame 931a and the outer working unit mounting frame 932a work independently and do not interfere with each other.
