[0040] In order to further improve the flexibility of the device, please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6In some possible embodiments, the connecting body 1 is composed of two parts, which are defined as the first connecting part 11 and the second connecting part 12 for the convenience of introduction, and the connecting body 1 further comprises a rotary driving member 13. The first connecting part 11 is used to be mounted on the tamping vehicle, the two tamping assemblies 2 are respectively mounted on the two sides of the second connecting part 12, and the first connecting part 11 is rotationally connected with the second connecting part 12. The rotary driving member 13 is mounted between the first connecting part 11 and the second connecting part 12, and is connected with the first connecting part 11 and the second connecting part 12 respectively, and is used to drive the second connecting part 12 to rotate relative to the first connecting part 11 or to be fixed. In operation, the operator can control the rotary driving member 13 to realize the rotation of the second connecting part 12 relative to the first connecting part 11, thereby driving the two tamping assemblies 2 to adjust the angle, so that the tamping accessory can adjust the overall working angle and direction according to the needs in the working process, and the flexibility of the accessory is enhanced.

[0041] Preferably, referring to Figures 4 to 6 In the embodiment, the first connecting part 11 is a quick-change connecting seat 111, which can be quickly connected and detached with the tamping vehicle, thereby facilitating the installation and replacement of the tamping accessory on the tamping vehicle. The second connecting part 12 is a mounting seat 112, which is used to mount and support the two tamping assemblies 2, so as to ensure that the tamping assemblies 2 can stably perform the tamping work.

Specifically, one end of each of the two first oil cylinders 41 close to the mounting seat 112 is rotationally connected with the mounting seat 112 through a rotating shaft, and the vibration driving member 5 is mounted on one side of the mounting seat 112, and the driving end of the vibration driving member 5 is connected with the rotating shaft through the mounting seat 112, and is used to drive the two first oil cylinders 41 and the tamping assemblies 2 connected therewith to vibrate synchronously through the vibration action of the vibration driving member 5, thereby realizing the vibration tamping of the ballast at the bottom of the sleeper. Through the vibration action of the vibration driving member 5, the bonding force between the ballasts can be more effectively broken, so that the ballasts are more loose and uniform, thereby improving the compactness and stability of the tamping.

[0044] Preferably, in the present embodiment, the vibration driving member 5 is a vibration motor.

Preferably, the limiting member 6 is a horizontally arranged limiting insulating plate, which is arranged between the four tamper rams. When the movable tamper ram 22 and the fixed tamper ram 21 are used simultaneously, the rail 8 will be abutted against the rail 8, so as to limit the depth of the movable tamper ram 22 and the fixed tamper ram 21 into the ballast. The limiting member 6 can ensure that the tamper ram does not excessively penetrate into the ballast, thereby avoiding unnecessary damage to the track bed structure.

[0046] In some possible embodiments, referring to Figure 4 and Figure 5 The bottom of the fixed tamper ram 21 and the movable tamper ram 22 is respectively provided with a clamping plate 221, and the length direction of the clamping plate 221 is perpendicular to the fixed tamper ram 21 or the movable tamper ram 22.

During the tamping operation, the clamping plate 221 can better clamp the ballast, so that the ballast is subjected to more uniform pressure during the tamping process, thereby further improving the compactness and uniformity of the tamping.

[0047] In a second aspect, the embodiments of the present scheme further provide a tamping vehicle comprising the four-head tamping tool capable of turnout operation as described in any one of the above embodiments.

During the operation, the tamping vehicle can drive the tamping tool to move along the track, and continuously tamps the ballast on both sides of the track.

[0048] Working principle: at the beginning of the operation, the operator first stably connects the tamping tool with the tamping vehicle through the connecting main body 1. Then, according to the operation requirements, the second connecting part 12 is driven to rotate relative to the first connecting part 11 by controlling the rotary driving member 13, so as to adjust the overall working angle and direction of the second connecting part 12 and the tamping assembly 2 thereon, to ensure that the tamping assembly 2 can conform to the shape and trend of the track bed. Next, according to the on-site requirements, the movable tamper ram 22 is switched to the first working position or the second working position relative to the fixed tamper ram 21 by starting the second oil cylinder 31 and controlling the extension and retraction of the second oil cylinder 31, so as to adapt to different interval turnout rails 8. At the same time, the first oil cylinder 41 and the vibration driving member 5 also start to work. The first oil cylinder 41 drives the first rotary body 23 to rotate around the connecting main body 1 through the extension and retraction of the first oil cylinder 41, and then drives the two tamping assemblies 2 to move relatively, to realize the clamping, extruding and vibrating operations on the ballast at the bottom of the sleeper. The vibration driving member 5 provides vibration driving force for the tamper ram assembly through the clamping driving member 4, to vibrate the ballast, so as to improve the compactness and stability of the tamping.
