[0041] The connection structure 4 includes a fixing plate A401 and a fixing plate B402;

[0042] The fixing plate A401 is fixed to the top end of the connecting plate 3; the fixing plate B402 is fixed to the top side of the tamping plate 2 on one side of the square groove 201; wherein, the fixing plate A401 and the fixing plate B402 are fixedly connected by bolts 403 and nuts 404, the bolts 403 pass through the holes on the fixing plate A401 and the fixing plate B402, and one end of the bolts 403 is threaded onto the nut 404.

[0043] The utility model has the advantages of installing a tamping plate 2 with a larger area, a large single tamping area, and a detachable tamping plate 2, by arranging a connecting plate 3, a tamping plate 2, a fixing plate A401, a fixing plate B402, bolts 403 and nuts 404, so as to solve the problem that a smaller tamping plate 2 has a small tamping area each time, resulting in an increase in the tamping time, and a large tamping plate 2 will occupy a larger space when not in use.

[0044] Specifically, the bottom end of the connecting plate 3 is set to a concave trapezoidal structure, and the four side plane sections of the connecting plate 3 contact and cooperate with the inner wall of the square groove 201. When the square groove 201 on the tamping plate 2 is connected to the connecting plate 3, the bottom end of the connecting plate 3 is easier to insert into the square groove 201.

[0045] Furthermore, the connection structure 4 also includes a guide rod 405, an L-shaped plate 406 and a round block 407;

[0046] Two guide rods 405 are symmetrically fixed on the top inner side of the fixed plate A401: the vertical section of the L-shaped plate 406 is sleeved on the two guide rods 405; two round blocks 407 are respectively fixed on the outer ends of the two guide rods 405; wherein, a spring 408 is sleeved on the guide rod 405 between the round block 407 and the vertical section of the L-shaped plate 406, and the two ends of the spring 408 are respectively fixedly connected to the round block 407 and the vertical section of the L-shaped plate 406, and the elastic coefficient of the spring 408 is selected and used by the technical personnel of this profession according to the actual situation; wherein, the horizontal end of the L-shaped plate 406 is penetrated and matched with the through hole 4021 opened at the top of the fixed plate B402.

Under the action of the spring 408, the vertical section of the L-shaped plate 406 moves back along the guide rod 405, and the horizontal end of the L-shaped plate 406 passes through the through hole 4021 to position the fixed plate A401 and the fixed plate B402. The bolt 403 passes through the holes on the fixed plate A401 and the fixed plate B402, and the end of the bolt 403 is threaded onto the nut 404. The hydraulic rammer body 1 pushes the connecting plate 3 and the rammer plate 2 downward to hit the road surface for rammering.

[0054] When removing the tamping plate 2, the hydraulic tamping machine body 1 is lifted by the vehicle, the nut 404 is loosened and the bolt 403 is removed, and the handle 4062 is held to pull the L-shaped plate 406 outward until the horizontal end of the L-shaped plate 406 leaves the through hole 4021, and the fixing plate A401 and the fixing plate B402 are no longer fixed, and the tamping plate 2 can be removed.
