Pile driver for civil engineering

Abstract

The invention discloses a pile driver for civil engineering. The pile driver for civil engineering comprises a chassis, a stand column and a crane jib. A rotation shaft of a drive motor is provided with an incomplete gear. The support is provided with a cross shaft rotationally connected with the support. The cross shaft is provided with a transmission gear and a rope reel. The stand column is provided with a first pulley. A second pulley is arranged at the top end of the crane jib. The lower end face of the crane jib is provided with two vertically downward guide sliding grooves. A pile hammer is arranged between the two guide sliding grooves. The two sides of the upper end of the pile hammer are both provided with supporting arms which are inclined and upward. A pile clamping mechanism connected with the stand column is arranged under the pile hammer. One end of a connection rod is fixedly connected with the bottom end of the stand column. The lower end of the stand column is connected with the chassis through a sliding mechanism. The chassis is provided with a hydraulic cylinder. The pile driver for civil engineering is simple in structure, good in pile driving upright performance, capable of continuously driving piles, high in pile driving efficiency, easy and convenient to operate and high in practicability.

Description

technical field [0001] The invention relates to a building construction machine, in particular to a pile driver for civil engineering. Background technique [0002] At present, in building construction, pile barrels are often used to ram and expand pile equipment, that is, pile drivers. The pile driver uses a pile barrel to insert into the ground, and the soil in the pile barrel is rammed out of the pile barrel by a heavy hammer, and at the same time, the soil around the pile is compacted. When a certain depth is reached, fill dry hard concrete or other filling materials from the side of the pile barrel, tamp it with a heavy hammer to the required quantity and hardness, lift the heavy hammer out of the pile barrel, put the steel bars and then pour the concrete into the pile barrel, then Lift the pile out. The pile driver for civil engineering is generally composed of pile hammer, pile frame and auxiliary equipment, etc., and the pile driver for civil engineering generally ...

AI Technical Summary

Problems solved by technology

The pile driver for civil engineering is generally composed of pile hammer, pile frame and auxiliary equipment, etc., and the pile driver for civil engineering generally drives the pile hammer up through the wire rope, and then uses the weight of the pile hammer to drive the pile. guide device, so the uprightness of pile driving is poor, and it is easy to tilt the pile body into the ground, and for multiple pile driving, it is necessary to move the entire pile driver, which increases difficulties and lower piling efficiency
