A river piling machine

Abstract

The invention discloses a riverway piling machinery, and relates to the technical field of water conservancy projects. The riverway piling machinery comprises a platform which suspends on a water surface; an accelerating device is arranged on the platform; an annular accelerating channel is formed in the accelerating device; a vertical guide cylinder is arranged out of the platform; the upper endof the guide cylinder is connected with the accelerating device; and a guide channel in the guide cylinder is tangent to the accelerating channel. The invention aims to solve technical problem that inorder to make a pile hammer have higher impact force and improve the piling efficiency, the height of a pile frame is improved so that the stability of a ship body is reduced and the ship body imbalance is initiated to cause an accident in the prior art. The riverway piling machinery is reasonable and simple in structural design; a hammer block has higher downward viscosity when the hammer blockis thrown out by utilizing centrifugal force, so that the hammer block has great dynamic potential energy to make up the loss of gravitational potential energy caused by the fact that the pile frame is not lifted, and the hammer block also has great impact force; meanwhile, a high pile frame is not erected, so that the stability of the ship body is kept, and the accident which is possibly caused by the imbalance of the ship body is avoided.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a river piling machine. Background technique [0002] River piling is a common water conservancy project, and currently piling on the river is generally carried out by piling boats. Except for the hull accident, the other parts of the piling ship have a similar piling structure on the bottom surface, with truss pile frames and piling hammers. During operation, the pile lifting, ship moving, and positioning work are completed through linkage mechanisms such as steel cables, pulleys, and winches. The explosive force of the pile hammer drives the pile into the water. The explosive force of the pile hammer comes from the gravitational potential energy after the pile hammer is lifted. The pile hammer falls freely, and the gravitational potential energy is converted into kinetic energy to impact the wooden pile, thereby driving the wooden pile into the river bed....

AI Technical Summary

Problems solved by technology

[0003] In such a construction plan, in order to obtain a greater impact force for the pile hammer and improve piling efficiency, the current method is to increase the lifting height of the pile hammer so that it has greater gravitational potential energy, which requires erecting a higher pile frame, but , the higher the pile frame is erected, the more unstable the hull will be, and accidents may occur due to imbalance. Therefore, a solution to increase the impact force of the pile hammer while maintaining the stability of the hull is needed
