With the further expansion of China's infrastructure construction scale, especially when some large-scale infrastructure projects have been launched, it provides a broad space for hydraulic vibrating hammers and makes them an indispensable key equipment. For example, increase deep excavation, large piles of large steel pipes and shell construction projects, soft soil foundation and rotary drilling rig construction projects, high-speed railway subgrade structures and infrastructure projects, land reclamation and construction sand management projects, and a wider range of municipal projects Construction, pipeline construction, support and treatment of sewage interception projects, retaining piles, and it are all inseparable, and the price of hydraulic vibrating hammers has therefore attracted much attention.

The current vibratory pile hammers can be divided into the following two categories. One type of enterprise uses a rotary vibrator, which also affects vibration through the rotation of an eccentric shaft (the center of gravity does not coincide with the rotation control center or the shaft with an eccentric mass); the other type mainly uses various reciprocating Vibration exciters usually produce different vibrations due to the hydraulic oil being used as the driving piston to circulate and reciprocate continuously in the cylinder. If a rotary vibrator is used, if the drive system device to improve the exciter is an electric motor, it is an electric vibration Pile hammer; if the drive technology device of the vibrator is a hydraulic motor, it is a hydraulic vibratory pile hammer. This kind of hydraulic vibratory pile hammer is more and more demanding in China, and the price of hydraulic vibratory hammer is also comparable to its price. The production quality is inseparable. The vibratory pile hammer using the rotary vibrator can be connected to several or dozens of units to vibrate synchronously for the construction of super large precast piles.

The basic working principle of the hydraulic system vibratory pile hammer: The working management principle of the hydraulic vibratory pile hammer is to make the hydraulic motor make a mechanical rotation by analyzing the hydraulic power source, so that each pair of eccentric wheels in different vibration boxes can be realized at the same angular velocity Reverse rotation; the centrifugal force generated during the rotation of the two eccentric wheels, the component connecting the center of the rotating shaft will cancel the interaction in the same unit time, and the components of the vertical direction of the connecting line between the center of the vibrating hammer will be mutually. The relationship is superimposed and finally there is no pile (pipe) excitation force.
