Technical Field

The invention relates to the field of construction machinery, in particular to an equidistant pile driver with adjustable transmission ratio.

Background

The pile driver is a piling machine which uses impact force to drive the pile into the stratum, and the pile hammer is attached between two parallel vertical guide rods (commonly called gantry) at the front part of the pile frame and is hoisted by a hoisting hook. The pile frame is a steel structure tower frame, and a winch is arranged at the rear part of the pile frame and used for hoisting the pile and the pile hammer. The front of the pile frame is provided with a guide frame consisting of two guide rods for controlling the piling direction so that the pile can accurately penetrate into the stratum according to the designed direction.

But the function that current pile driver ubiquitous can not remove, in road and bridge construction process, often need carry out the pile construction, the continuous pile of automatic positioning must improve the progress of construction, consequently, await urgent need to develop a neotype equipment that can pile automatically in succession equidistance.

Disclosure of Invention
