Description

A device for efficiently and safely connecting a drill pipe for a pile driver

technical field

The present invention relates to the technical field of construction equipment, and more particularly, to a device for efficiently and safely connecting a drill pipe of a pile driver.

Background technique

In the construction of the pile foundation, a large number of continuous drill pipes are used when the project needs to form deeper holes. The current conventional method is: as shown in Figure 1, the pre-drilled process holes are first stored in the drill pipe to be connected, and the pile driver is driven to the process when drilling is required. Put down the power head at the hole to complete the drilling; then lift the power head to the highest position, use the auxiliary crane to hoist the drill pipe to the bottom of the power head, connect the drill pipe to be connected with the drill pipe below, remove the crane, and use the hanging basket to lift the drill pipe to the bottom of the power head.
