Vibration piling hammer

Abstract

The vibratory pile driving hammer includes motor, belt drive system, pile-drawing vibration-reducing system, pressuziing vibration-reducing system, eccentric body and exciter. It is characterized by that the interior of pile-drawing vibration-reducing system of said vibratory hammer is equipped with closed pile-drawing vibration-reducing spring, and the interior of the described pressurizing vibration-reducing system is equipped with closed pressurizing vibration-reducing spring, the described springs are closed in their respective box bodies, the described eccentric body is equipped with oil ring with directional oil channel, and on the belt drive cover box a microhole is set, and the inner walls of all the box bodies are coated with sound-absorbing coating layer.

Description

technical field [0001] The invention relates to a construction engineering machine, in particular to a vibratory hammer for piling in the construction of construction engineering. Background technique [0002] In the current technology, diesel pile drivers and ordinary vibratory hammers used in the market are generally used for piling in construction projects. This kind of diesel pile driver is an impact hammer driven by the explosive force of a diesel engine to move the pile hammer. The impact noise produced by it It is very large, and the exhaust gas emitted by the diesel hammer seriously pollutes the environment, its construction speed is slow, and the infrastructure cost is high, so it is prohibited to use in urban construction projects at home and abroad. Ordinary vibratory piling hammer has fast construction speed, no exhaust gas and impact noise of diesel hammer, but the vibration noise caused by continuous vibration is relatively large, coupled w...

Problems solved by technology

[0002] In the current technology, diesel pile drivers and ordinary vibratory hammers used in the market are generally used for piling in construction projects. This kind of diesel pile driver is an impact hammer driven by the explosive force of a diesel engine to move the pile hammer. The impact noise produced by it It is very large, and the exhaust gas emitted by the diesel hammer seriously pollutes the environment. Its construction speed is slow and the infrastructure cost is high. It is forbidden to use it in urban construction projects at home and abroad.

Ordinary vibratory piling hammer has fast construction speed, no exhaust gas and impact noise of diesel hammer, but the vibration noise caused by continuous vibration is relatively large, coupled with improper vibration reduction parameters and balance processing, poor vibration reduction effect, lateral vibration, shimmy, etc. Vibration and the impact of piling on the horizontal vibration of the ground, the combination of various factors, the noise during the construction process exceeds the environmental protection requirements, the efficiency is reduced, and the energy waste is large. Some cities in China also prohibit the use of old city renovation projects. I hope there will be a A vibratory hammer with high efficiency and low energy consumption in line with national environmental protection standards
