Description

Technical Field

[0001] The utility model relates to the technical field of railway track tamping, in particular to a railway track tamping device. Background Art

[0002] Railway is also an important means of transportation nowadays, which has made great contributions to people's travel and the transportation of goods. However, trains transport goods every day and will run on the rails constantly, which will inevitably put pressure on the rails, thereby loosening the ballast at the bottom of the rails, causing the sleepers and rails to sink, making the height of the rails inconsistent, thereby affecting the normal travel of the train, causing the train to shake when passing through uneven rails, and when the rails sink seriously, it may also cause the train to derail, causing serious safety hazards. For this reason, it is necessary to vibrate the ballast under the rails and sleepers, and after replacing the tracks, sleepers and ballast, it is also necessary to vibrate and compact the newly laid ballast to increase the density of the ballast, thereby enhancing the load-bearing capacity of the railway roadbed. At present, most of the tamping work for ballast is carried out manually, and the loose rails need to be lifted first, and then tamped. The efficiency of pure manual tamping of ballast is low, and the labor cost and construction time are long, which is inefficient. Utility Model Content

[0006] By adopting the above technical solution, the supporting flat pressing bottom plate can be pushed out by the push of the first hydraulic cylinder, so that the supporting flat pressing bottom plate contacts the slag and the mounting base is lifted up. The rotating wheel screwed into the mounting base will drive the guide rail to rise together with the rising of the mounting base, and the mounting base can be moved on the guide rail through the supporting roller, which can save a lot of manual operation and improve the efficiency of tamping.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the railway track tamping device:

[0018] 1. The support roller can facilitate the installation base to move on the guide rail. When it reaches the place where tamping is required, the first hydraulic cylinder can be started to push out the support flat pressing bottom plate, so that the support flat pressing bottom plate contacts the slag, and the installation base is lifted up, driving the rotating wheel to rise together, so that the rotating wheel drives the guide rail and the track to rise together, and then the vibrating tamping rod is lowered to tamp, so that the slag is tightened and the gap of the raised guide rail is filled at the same time, reducing manual operation and improving tamping efficiency;

[0019] 2. When the width of the sleepers is inconsistent, the screw can be turned to drive the sliding base to move to both sides to open or tighten. The sliding base can be limited by the fit between the sliding ejection bottom plate and the sliding base, so that the sliding base drives the vibrating tamping rod to move together and adjust to the appropriate spacing to suit the guide rails with different spacings;

[0020] 3. When the fuel linkage machine rotates, the shaft in the connecting soft shaft will rotate, causing the vibration tamping rod to rotate and vibrate, and the spring will reduce the energy lost when the vibration tamping rod vibrates. The vibration tamping rod and the sliding base are flexibly connected. At the same time, the position of the vibration tamping rod can be fixed by clamping the vibration tamping rod with the installation block and the inlaid fixing block, which makes it convenient to remove the vibration tamping rod for maintenance and adjustment, so that when the installation base moves on the guide rail, the vibration tamping rod will not be damaged by contact with slag.
