At present, the pile breaking mechanism is generally arranged under the fuselage, with a fixed height from the ground. In addition, since the space under the fuselage is relatively small, it is inconvenient to use a sling to raise and lower the pile breaking mechanism, and the height adjustment of the pile breaking mechanism is relatively cumbersome. Therefore, the pile breaking mechanism in the prior art can only break prefabricated piles of fixed height. This traditional pile breaking has too many limitations and the construction efficiency is extremely low. Utility Model Content

[0009] The second connection assembly includes a second steel wire rope. The bottom end of the pile clamping mechanism is provided with four second lower hanging ears arranged in a square or rectangle. Both ends of each second steel wire rope are respectively connected to the corresponding upper hanging ear and the second lower hanging ear.

[0017] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1As shown, the adjustable pile-breaking mechanism for a static pile driver of this embodiment comprises a pile-breaking mechanism body 1, the pile-breaking mechanism body 1 is located directly below the pile clamping mechanism 2, the pile clamping mechanism 2 is driven to rise and fall by the pile-pressing mechanism 3 arranged above it, the top of the pile-breaking mechanism body 1 is provided with a first connecting component 41 for connecting with the static pile driver body and a second connecting component 42 for connecting with the bottom end of the pile clamping mechanism 2, when only the first connecting component 41 is connected to the static pile driver body, the height of the pile-breaking mechanism body 1 from the ground is the lowest, and it is used to break the precast pile 5 with the lowest height protruding from the ground; when the first connecting component 41 and the second connecting component 42 are connected to the static pile driver body and the pile clamping mechanism 2 at the same time, the height of the pile-breaking mechanism body 1 from the ground can be adjusted with the rise and fall of the pile clamping mechanism 2, and precast piles 5 of different heights can be broken. The utility model has a simple structure and can improve the convenience of pile-breaking construction.

[0019] In this embodiment, the first connecting assembly 41 and the second connecting assembly 42 are each provided with four groups, and the four groups of the first connecting assembly 41 and the four groups of the second connecting assembly 42 are all symmetrically arranged with the longitudinal center line of the prefabricated pile 5 as the symmetry axis. The first connecting assembly 41 and the second connecting assembly 42 are each provided with four groups arranged symmetrically, so that the pile breaking mechanism can perform the pile breaking work more stably without shaking.

[0021] When the first steel wire rope is connected to the bottom end of the fuselage of the static pile driver and the second steel wire rope is not connected to the pile clamping mechanism 2, the pile breaking mechanism body 1 cannot be lifted or lowered and can only be suspended under the fuselage without moving. At this time, the height of the prefabricated pile 5 protruding from the ground can be the lowest. When the first and second steel wire ropes are connected to the fuselage and the pile clamping mechanism at the same time, the pile clamping mechanism 2 can be lifted or lowered a certain distance by the pile pressing cylinder of the pile pressing mechanism 3 to drive the pile breaking mechanism body 1 to adjust the height from the ground.
