Description

Technical Field

[0001] The utility model relates to a hammer pressing mechanism, in particular to a hammer pressing mechanism with adjustable pressure and adjustable frequency, belonging to the technical field of hammer pressing mechanisms. Background Art

[0002] The hammer mechanism is a mechanism that hammers the soil during the construction process to make the soil more compact for subsequent construction. During the work process, different weights are added according to different soil conditions to tamp the land to make the soil dense.

[0003] The hammer mechanism includes a hydraulic hammer mechanism and a free-fall hammer mechanism. In the common free-fall hammer mechanism, the hammer block is raised to a certain height by a lifting device and then released. The hammer block falls freely and hits the ground. However, this operation method is very dangerous during operation because the hammer block is free to fall without restraint. If it encounters an uneven ground, the hammer block may roll to one side at the moment of landing. At the same time, since the power of the lifting equipment is fixed, the hammer frequency cannot be adjusted, which makes it not very versatile. Utility Model Content

A cable 16 is wrapped around the outer surface of the rotating rod 6, and the other end of the cable 16 is connected to the connecting rod 15.

[0029] When the utility model is in use: first, the turntable 10 is rotated, and the rotation of the turntable 10 drives the driving motor 11 to rotate.
