Problems solved by technology
[0002] At present, most of the pile drivers commonly used in construction projects are to lift the pile hammer from a low place through the hoist, generate a large gravitational potential energy, make the pile hammer fall freely, convert the stored gravitational potential energy into kinetic energy, and impact the pile body. Pile driving process; increase the strength of the pile by raising the height of the pile hammer, which is very inefficient; due to safety factors, the pile hammer cannot be raised too high, which also limits the working capacity of the pile driver

The invention relates to an electromagnetic pile driver. The electromagnetic pile driver comprises a cylindrical pile frame, two long and narrow clamping grooves which extend in the axial direction of the pile frame are formed in the inner wall of the pile frame, conductive substrates are arranged along the inner walls of the long and narrow clamping grooves in an equally-spaced mode, a hard guide rod is arranged at the position of the axis of the pile frame, and permanent magnet columns corresponding to the conductive substrates in a one-to-one mode are distributed on the guide rod in an equally-spaced mode. The electromagnetic pile driver further comprises a pile hammer, a guide hole is formed in the axis of the pile hammer, two flanges matched with the clamping grooves are arranged on the outer surface of the pile hammer, the outer surfaces of the flanges are respectively provided with a conductive contact, an electromagnet surrounding the guide hole is arranged in the pile hammer, and two joints of the electromagnet are connected to the conductive contacts respectively. According to the pile driver, the pile body can be hammered in the small stroke with the giant impact force, efficient piling is achieved, and on the premise that the safety of a construction site is ensured, the working capability of the pile driver is greatly improved.
Description
technical field [0001] The invention relates to a construction machine, in particular to a pile driver. Background technique [0002] At present, most of the pile drivers commonly used in construction projects are to lift the pile hammer from a low place through the hoist, generate a large gravitational potential energy, make the pile hammer fall freely, convert the stored gravitational potential energy into kinetic energy, and impact the pile body. Pile driving process: Increase the strength of the pile by raising the height of the pile hammer, which is very inefficient; due to the limitation of safety factors, the pile hammer cannot be lifted too high, and the working capacity of the pile driver is also limited. Contents of the invention [0003] In view of the above problems, the present invention provides an electromagnetic pile driver, which can beat the pile body with a huge impact force within a small stroke, realize efficient pile driving, and greatly improve the w...
