Pile driver

Abstract

The invention discloses a pile driver which comprises a work frame. A water tank is installed on the top of the work frame. A water pump is installed on the top of the water tank. A liquid outlet in one side of the water pump is connected with a pile hammer through a liquid pipe. The top of the pile hammer is connected with a pile hammer moving frame through a hydraulic hammer rod. The two sides of the pile hammer moving frame penetrate a pile frame and are connected with a lifting device in a pile frame inner cavity in the left side and a pulley of a pile frame inner cavity in the right side correspondingly. The bottom of the lifting device is connected with an output shaft of a lifting motor. By the adoption of the pile driver, through integrated matching of the lifting motor and the lifting motor, the pile hammer can be driven to move, and the pile driving work becomes more easily; and meanwhile, the water tank, the water pump and the liquid pipe are matched, a liquid head in an inner cavity of the pile hammer is matched, after the pile hammer is driven into the underground part, gluing liquid flows out through the liquid head, a pile body and the underground part are connected through the gluing liquid and can be connected more stably, and the pile driver is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a pile driver. Background technique [0002] At present, most of the pile drivers on the market use the hoist to drive the pulley block to carry out a process of gravity piling. This type of pile driver has poor piling strength and is often prone to skewing of the pile hammer. At the same time, due to insufficient piling strength Large, when it is often necessary to increase the strength, it is often necessary to raise the pulley block, but often raising the pulley block requires proofreading, which greatly wastes working time and makes the piling operation time longer. Contents of the invention [0003] The purpose of the present invention is to provide a pile driver with simple structure, convenient use and strong piling force. At the same time, it is equipped with a water tank matched with a pile hammer to facilitate the outflow of glue, so that the connection...
