In the specific embodiment of the present application, the support device 16 adopts a hydraulic cylinder, which has stable output and large supporting force.

[0038] In the specific embodiment of the present application, as Figure 5 shown, the tamping mechanism 3 includes two support guide rails 18 fixedly arranged in parallel on the walking frame 7. A tamping support 19 capable of sliding along the support guide rails 18 is arranged between the two support guide rails 18. The upper ends of the two support guide rails 18 are fixedly connected by a support cross beam 20. A tamping telescopic structure 21 is fixed on the tamping support 19. The telescopic arm of the tamping telescopic structure 21 is fixed on the support cross beam 20.

[0039] In the specific embodiment of the present application, in order to ensure the stability of the support guide rails 18, both sides of the support cross beam 20 are fixedly connected to the walking frame 7 through downward pull support rods 23.

[0040] As Figure 1 、 Figure 5 shown, multiple groups of tamping mechanisms 3 are symmetrically arranged on the walking frame 7.

At the same time, a vibrating rod 27 is hinged on the tensioning arm 26, and the vibrating rod 27 is rotationally connected to the eccentric wheel 25. During use, the output rod of the lower insertion oil cylinder 24 is used to control the tensioning arm 26 to swing around the rotation center of the rotational connection axis between the vibrating rod 27 and the tensioning arm 26. At the same time, the rotation of the eccentric wheel 25 drives the vibrating rod 27 to vibrate up and down, so as to achieve the purpose of tamping the foundation stone at the bottom of the guide rail by the pick head 28 on the tensioning arm 26.

[0042] As Figure 6 shown, both ends of the vibrating rod 27 connected to the eccentric wheel 25 are respectively hinged with a tensioning arm 26, and the two tensioning arms 26 are arranged oppositely, which can tamp the foundation stone under the same sleeper.

[0043] In the specific embodiment of the present application, as Figure 7 shown, the connecting mechanism 5 includes a connecting plate 29. A connecting joint 30 is arranged at the upper end of the connecting plate 29, and a hinged connecting rod 31 is arranged at the lower end of the connecting plate 29. The hinged connecting rod 31 is hinged to the lower end of the connecting plate 29. A connecting head for fixedly connecting with the frame of the track lifting and tamping machine is arranged at the end of the hinged connecting rod 31. In the present application, the connecting plate 29 is used as the rotational connection joint part between the hinged connecting rod 31 and the connecting joint 30. After connecting the hinged connecting rod 3 to the connecting hole 10 on the connecting support seat 8 during the handling process, and then fixedly connecting the handling tool to the connecting joint 30. During the lifting process, since the hinged connecting rod 31 is hinged to the lower end of the connecting plate 29, the rotation of the track lifting and tamping machine will not affect the connecting part of the connecting joint 30, thus ensuring the safety during the hoisting process and being able to ensure the hoisting accuracy at the same time.

[0044] In the specific embodiment of the present application, as Figure 8 shown, the connecting joint 30 includes two joint plates 32 fixed on the connecting plate 29. A connecting fixing rod 33 is fixed between the two joint plates 32. The connecting fixing rod 33 is used for connecting with the handling tool. Specifically, for example, the gripper of a mechanical device can directly grab the connecting fixing rod 33, or a lifting hook can be directly hung on the connecting fixing rod 33, so as to realize the hoisting of the overall connecting device.

[0045] The mechanical equipment adopted in the present application can be a railway excavator. By being used in combination with the railway excavator, the circuit and oil circuit are introduced from the railway excavator, and the power is provided by the excavator. The tamping and track lifting operations are controlled in a short-distance remote control manner, and at the same time, the traveling of the excavator equipment is linked with the operation process of this device.

[0046] As Figure 8As shown, the articulated connecting rod 31 is articulated to the lower end of the connecting plate 29 through the hinge seat 34.

[0047] Specifically, in an embodiment of the present application, as Figure 2 shown, the hinge seat 34 is welded and fixed to the lower end of the connecting plate 29. A groove is provided in the hinge seat 34. One end of the articulated connecting rod 31 is a hemispherical structure. The hemispherical structure end of the articulated connecting rod 31 is arranged in the groove of the hinge seat 34. The other end of the articulated connecting rod 31 passes through the hinge seat 34 and is located outside. The hemispherical structure end of the articulated connecting rod 31 can rotate relative to the hinge seat 34, thus forming an articulated structure. Lubricating oil can be added into the hinge seat 34 to reduce the friction between the hinge seat 34 and the articulated connecting rod 31.

[0048] In the specific implementation manner of the present application, a groove is provided in the hemispherical structure end of the articulated connecting rod 31. A spring 36 is arranged in the groove of the hemispherical structure end of the articulated connecting rod 31. The spring 36 is located between the articulated connecting rod 31 and the inner bottom of the hinge seat 34. The spring 36 is used to ensure that the articulated connecting rod 31 and the hinge seat 34 remain in contact, and prevent the articulated connecting rod 31 from being pressed into the hinge seat 34 during non-use or disassembly and installation.

[0049] The hinge seat 34 includes a bottom plate and side plates. The side plates and the bottom plate are welded to form the structure of the hinge seat 34. The inner side of the side plates is an arc surface structure. One end of the side plates welded to the bottom plate is an open structure, which can fit with the surface of the hemispherical structure of the articulated connecting rod 31 to ensure the stability of the rotation of the articulated connecting rod 31. During the installation process, the articulated connecting rod 31 is placed into the side plates from the open structure of the side plates, and then the spring is placed. The side plates are placed in the tooling to ensure that the articulated connecting rod 31 remains in contact with the inner wall of the side plates, that is, the articulated connecting rod 31 is in a freely suspended state. Then the side plates and the bottom plate are welded. Or the side plates with connecting ear structures and the bottom plate are bolted together, which is convenient for maintenance work.

[0050] A fastening bolt 35 is provided on the side wall of the hinge seat 34. The fastening bolt 35 can rotate on the side wall of the hinge seat 34. The end of the fastening bolt 35 can abut against the hemispherical structure of the articulated connecting rod 31 for fixing the articulated connecting rod 31. After the lifting of the track lifting and tamping machine is completed and it is in a stable state, the articulated connecting rod 31 is fixed by adjusting the fastening bolt 35, which ensures the stability of the track lifting and tamping machine during the lifting process and prevents its shaking from affecting the accuracy of the lifting and placement.

[0051] In this application, the frame 1 serves as the connection and support mechanism for the tamping mechanism 3 and the track lifting device 4. As an integral structure, it can achieve tamping and track lifting operations. At the same time, it can use the robotic arm 6 of the track construction vehicle to lift through the coupling device. The structure of this application is simple, can achieve the integrated function of track lifting and tamping, and uses the robotic arm for lifting, greatly reducing the labor intensity of workers, significantly improving the tamping quality and operation efficiency, and greatly reducing the labor intensity.
