Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of track lifting and tamping integrated machine connection, and particularly relates to a flexible connection device for the track lifting and tamping integrated machine. Background Art
[0002] Tamping machines are essential tools for railway line maintenance, used for regular track tamping to ensure track stability and driving safety. During new railway line construction, tamping machines are used to tamp the ballast in the trackbed to ensure the stability of the track foundation. Tamping machines are also used for specialized tamping operations in special sections, such as switches and tunnels, to ensure track stability in these areas. Their vibration system compacts the ballast, improving the trackbed's buffering capacity and eliminating track defects such as dead slabs. During tamping, a pair of high-frequency vibrating tamping picks simultaneously insert ballast into both sides of the sleeper. At a specified depth, the ballast is compacted through a relative clamping action, causing it to flow, aggregate, and reorganize, thereby stabilizing the track. However, due to the particularity and special environment of railway construction, tamping machines are generally mainly lifted and placed on the railway to be constructed by manual labor. As the construction progresses, the tamping machine travels along the track. During the driving process, it is mainly controlled by manual or mechanical equipment to move forward or backward, and large machinery cannot be used to control it. During the lifting process by manual or mechanical equipment, it is mainly hoisted on the frame of the tamping machine with a rope. The tamping machine is prone to deflection under the action of its own gravity, and the rope is prone to knotting and the safety of the lifting cannot be ensured. Utility Model Content

[0025] As right Figure 1When the lifting device is lifted up, the lifting link 1 is tightened, and the lifting link 1 is tightened. The lifting link 1 is loosened, and the lifting link 1 is loosened, and the lifting link 1 is loosened.
[0026] In the specific implementation of this application, Figures 2 to 4 As shown, the connecting joint 2 includes two connecting plates 4 fixed on the connecting plate 1, and a connecting fixing rod 5 is fixed between the two connecting plates 4. The connecting fixing rod 5 is used to connect with the handling tool. Specifically, the gripper of the mechanical equipment can directly grab the connecting fixing rod 5, or a hook can be used to directly hang on the connecting fixing rod 5, thereby realizing the lifting of the overall connecting device.
[0027] In the specific implementation of this application, Figure 1 As shown, two parallel connecting fixing rods 5 are arranged between the two joint plates 4. By utilizing the structure of the two parallel connecting fixing rods 5, the connecting joint 2 can be stably fixed when a mechanical gripper is used for grabbing, thereby ensuring the stability between the connecting device and the track lifting and tamping machine.
[0028] like Figure 1 、 Figure 2 As shown, the hinged connecting rod 3 is hinged to the lower end of the connecting plate 1 through the hinge seat 6.
[0029] Specifically, in one embodiment of the present application, Figure 2 As shown, the articulated seat 6 is welded and fixed to the lower end of the connecting plate 1, and a groove is provided in the articulated seat 6. One end of the articulated connecting rod 3 is a hemispherical structure, and the hemispherical structure end of the articulated connecting rod 3 is provided in the groove of the articulated seat 6. The other end of the articulated connecting rod 3 passes through the articulated seat 6 and is located on the outside. The hemispherical structure end of the articulated connecting rod 3 can rotate relative to the articulated seat 6, thereby forming a hinge structure. Lubricating oil can be added to the articulated seat 6 to reduce the friction between the articulated seat 6 and the articulated connecting rod 3.
[0030] In a specific embodiment of the present application, a groove is provided at the hemispherical structure end of the articulated connecting rod 3, and a spring 7 is provided in the groove of the hemispherical structure end of the articulated connecting rod 3. The spring 7 is located between the articulated connecting rod 3 and the inner bottom of the articulated seat 6. The spring 7 is utilized to ensure that the articulated connecting rod 3 and the articulated seat 6 maintain contact, and the articulated connecting rod 3 is pressed into the articulated seat 6 when not in use or during disassembly.
[0031] Specifically, a fastening bolt 8 is provided on the side wall of the articulated seat 6. The fastening bolt 8 can rotate on the side wall of the articulated seat 6. The end of the fastening bolt 8 can rest on the hemispherical structure of the articulated connecting rod 3 to fix the articulated connecting rod 3. When the track lifting and tamping machine is in a stable state after the hoisting is completed, the articulated connecting rod 3 is fixed by adjusting the fastening bolt 8, thereby ensuring the stability of the track lifting and tamping machine during the hoisting process, and preventing its shaking from affecting the accuracy of hoisting and placement.
[0032] In the specific implementation of this application, Figure 2 As shown, the hinge seat 6 comprises a base plate and side plates, which are welded to the base plate to form the hinge seat 6 structure. The inner side plate has a curved surface structure, and the end of the side plate welded to the base plate has an open structure that can fit the hemispherical surface of the hinged connecting rod 3, ensuring the stability of the hinged connecting rod 3's rotation. During installation, the hinged connecting rod 3 is inserted into the side plate through the opening structure of the side plate. Then, the spring is inserted and the side plate is placed into the tooling to ensure that the hinged connecting rod 3 maintains contact with the inner wall of the side plate, that is, the hinged connecting rod 3 is in a freely suspended state. The side plate is then welded to the base plate. Alternatively, a side plate with a connecting ear structure can be used to connect the side plate to the base plate via bolts to facilitate maintenance.
[0033] In another embodiment of the present application, Figure 1 and Figure 4 As shown, the hinge seat 6 is fixed to the lower end of the connecting plate 1 by bolts, and maintenance work is performed on the hinge seat 6 according to the wear and tear of the hinge seat 6 at the lower end of the connecting plate 1.
[0034] In the present application, a flexible connection device for a track lifting and tamping machine is provided, in which a connecting plate 1 is used as a rotational connection joint portion between an articulated connecting rod 3 and a connecting joint 2. During transportation, the articulated connecting rod 3 is fixedly connected to the frame of the track lifting and tamping machine, and then the transportation tool is fixedly connected to the connecting joint 2. During the lifting process, since the articulated connecting rod 3 is hinged to the lower end of the connecting plate 1, the rotation of the track lifting and tamping machine will not affect the connection portion of the connecting joint 2, thereby ensuring safety during the lifting process and ensuring the accuracy of the lifting.
