The operation mode of the hydraulic tamper can be divided into a free drop hammer type and a forced drop hammer type, wherein the free drop hammer type (single action): the hydraulic cylinder lifts the hammer body to a set height and then releases the hammer body, and the hammer body falls freely; after falling down, the hammer body strikes the assembly of the lower hammer body and the tamping plate through the hammer pad, and the tamping plate is driven to compact the ground; forced drop hammer (double action): the hydraulic cylinder lifts the hammer body to a set height and then rapidly applies force in a reverse direction, and the hammer body is accelerated to fall under the combined action of gravity and the thrust of the hydraulic cylinder; after falling down, the hammer body strikes the assembly of the lower hammer body and the tamping plate through the hammer pad, and the tamping plate is driven to compact the ground.
The hydraulic dynamic compactor can be switched between a free falling weight type hydraulic compactor and a forced falling weight type hydraulic compactor by controlling the gear locking device 180, namely, one hydraulic compactor has two operation modes.

The specific motion cycle of the free falling hammer is described in the foregoing, and is not described in detail herein.
The experiment of this application reachs, through control hydro-cylinder 120 flexible volume and gear locking device 180's runtime can obtain different tamping effects.
In the experiment of the present application, it is found that if the same tamping effect is maintained for a long time (i.e., the expansion amount of the oil cylinder 120 is kept unchanged), whether the free drop hammer or the forced drop hammer is adopted, some teeth (for a long time) on the gear set 160 are stressed greatly and other teeth are stressed less, and therefore, fatigue damage of some teeth on the gear set 160 is easily caused in the past, which is earlier than damage of other teeth, and adverse effects are caused on the service life of the whole gear set 160.
In view of the above problem, as shown in fig. 7, the present embodiment is added with a gear driving assembly 190 on the basis of the first embodiment; the gear driving assembly 190 plays a role in driving the gear set 160 to rotate after the gear set 160 and the rack set 170 are disengaged, so as to ensure that the stress duration of each tooth of the gear set 160 is similar.

the ramming plate is positioned on the inner wall of the shell, which is close to the ground, is a block-shaped body and plays a role in bearing the impact of the rammer so as to compact the ground.
8. The method of installing a hydraulic tamper tamping device according to claim 3,
the two groups of gear driving assemblies are respectively used for driving the first gear and the second gear, and each group of gear driving assemblies comprises a motor, a friction wheel and a motor control device;
the motor is positioned on the gear rack;
the friction wheel is a wheel with a rough surface, is positioned on the output shaft of the motor and is attached to the gear of the gear set;
after the gear set and the rack set are disengaged, the motor runs, and the friction wheel drives the first gear and the second gear to rotate for a certain angle;
and the motor stops running after the gear set and the rack set are meshed.
