Pile hammer of a building construction punching pile driver

Abstract

The invention provides a pile hammer of a construction punching pile driver, which effectively solves the problem that the hammer head of the existing punching pile driver is prone to inclination of the pile hole, the hammer head is easy to be stuck in the hole, and the plum blossom hole is easy to appear. The problem of hole collapse; the technical solution is to include the main body of the hammer head of the punching pile driver, the center of the main body has a central hole, the central hole has a central shaft, the upper end of the central shaft has a counterweight, and there is a groove on the central shaft. There is a cylinder on the central axis, a slider on the inner wall of the cylinder, an annular plate is set on the cylinder, and a telescopic rod is arranged on the annular plate, which can drive the telescopic rod to rotate, and a cylinder is installed on the end of the telescopic rod away from the central axis. shaped roller, and the central shaft is fitted with a rotatable annular sleeve; the invention has an ingenious structure, which can also compact the side wall of the pile hole to build the wall during the punching process, reducing the occurrence of hole collapse and effectively avoiding the hammer The head is deflected to prevent the hammer head from being stuck in the pile hole, realize punching and reaming, and improve the bearing capacity of the pile foundation.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a pile hammer of a construction punching pile driver. Background technique [0002] In bridge construction, early piling is very important for the stability and safety of the bridge. Bridge piling is a construction method in which piles of various materials are driven, pressed, vibrated or screwed into the foundation soil with special machines. Commonly used hammering method, vibration method, water jet method and pile pressing method. Among them, the hammering method is to use the impact energy of the pile hammer to overcome the resistance of the foundation soil to the pile, and drive the pile to a predetermined depth, which is suitable for soft plastic or plastic cohesive soil layers. The main equipment used are pile frame, pile hammer, power equipment and so on. [0003] During the construction process, the pile hammer hammers the ground. During repeated hamm...
