[0002] In the field of railway repair and maintenance, due to the long-term operation of the ballasted trackbed, the track wheels of the train roll and run on the rails, causing the rails to be stressed and transmitted to the ballasted trackbed, so that the gravel constituting the ballasted trackbed is frequently stressed and displaced to a certain extent, which in turn causes the density of the gravel under the sleepers to decrease, which not only affects the driving comfort, but also easily causes accidents such as rail damage and derailment, which can cause major safety accidents in severe cases. Therefore, it is necessary to regularly inspect the ballasted trackbed and compact the ballasted trackbed to improve the connection strength between the sleepers and the ballasted trackbed. The generally adopted means is that the railway maintenance personnel use a handheld tamping machine to compact the ballasted trackbed near the sleepers so that the density of the gravel around and below the sleepers meets the requirements. Although this method can effectively compact the ballasted track bed, the work intensity is high and the work efficiency is extremely low. During the long-term repetitive work of railway maintenance personnel, fatigue work is very likely to occur, resulting in safety accidents. Utility Model Content

The vertical adjustment mechanism 14 of the utility model is installed on the side of the plate-type vertical seat 1 close to the rail, and the vertical adjustment mechanism 14 is connected to the limiting assembly, and the limiting assembly is slidably connected to the top of the rail, and the crawler chassis 4 is assembled at the lower end of the mounting seat 2. The working principle and advantages of the utility model are as follows: the utility model controls the crawler chassis 4 to move, so that the crawler chassis 4 drives the mounting seat 2, the plate vertical seat 1 and the tamping seat 3 to move along the length direction of the railway on one side of the rail, and controls the telescopic length of the inclined member 8 so that the lower end surface of the tamping seat 3 contacts the surface of the ballasted track bed at the end of the sleeper; controls the vibrator 10 to drive the tamping seat 3 to tamp the ballasted track bed, thereby achieving the purpose of compacting the ballasted track bed. In addition, in order to prevent the tamping seat 3 from deviating from the entire tamping machine during the tamping process, the utility model connects the limiting assembly to the top of the rail in a sliding manner, and the limiting assembly limits the spacing between the mounting seat 2 and the rail; and according to the height difference between the rail and the ballasted track bed, the vertical adjustment mechanism 14 can be adjusted to drive the limiting assembly to move vertically, ensuring that the limiting assembly can be slidably connected to the top of the rail.

In this embodiment, according to the height difference between the ballasted track bed and the rails, the operating hand wheel 1405 is rotated to drive the transmission screw 1404 to rotate, and the transmission screw 1404 drives the sliding block 1403 to move along the sliding rail 1402, and the sliding block 1403 drives the limiting assembly to move in the vertical direction, so that the limiting assembly is slidably connected with the top of the rail.

[0032] As a preferred embodiment of the present invention, Figure 4 , 5 As shown, the limiting component includes a mounting plate 11 and two connecting members 12. The mounting plate 11 is detachably connected to the sliding block 1403, and the mounting plate 11 extends along the length direction of the rail. The two connecting members 12 are respectively hinged at the two ends of the mounting plate 11, and a buckle 13 is installed at one end of each connecting member 12 away from the mounting plate 11, and the buckle 13 is elastically buckled on the top of the rail. The connecting member 12 includes a second electric cylinder, the cylinder body of the second electric cylinder is hinged to the mounting plate 11, and the cylinder rod of the second electric cylinder is connected to the buckle 13. The specific structure of the buckle 13 is that the buckle 13 includes two oppositely arranged buckle seats 1301, a buckle opening 1303 is formed between the two buckle seats 1301, and the top of the rail is located in the buckle opening 1303.

When it is necessary to release the fastening of the fastening member 13 to the top of the rail, the fastening bolt 1306 is screwed down, and then the adapter seat 1302 movably connected to the cylinder rod of the second electric cylinder is moved so that the diameter of the fastening opening 1303 gradually increases, and then the second electric cylinder is lifted along its hinge point, so that the fastening member 13 is separated from the top of the rail. When it is necessary to fasten the fastening member 13 to the top of the rail, two fastening seats 1301 are set on both sides of the top of the rail, and then the fastening bolts 1306 are used to connect and fix the connection plate 1305 to the corresponding adapter seat 1302, so that the top of the rail is confined in the fastening opening 1303. In this embodiment, when the tamping operation is performed, the fastening member 13 will also vibrate.
