Problems solved by technology

[0003] When the existing pile driver strikes the wooden pile progressively, the pile hammer is generally driven up by the steel wire rope, and then the pile driver is driven down by the weight of the pile hammer to drive the pile. And the steel wire rope has low lifting efficiency, which leads to the defect of low piling efficiency of the pile driver

Abstract

The invention discloses a pile driver for a construction site. The pile driver comprises a bottom plate, a support and a pile driving mechanism, wherein the pile driving mechanism comprises a pile driving barrel, a driving mechanism and a clamping mechanism; the driving mechanism comprises a first gear, a second gear, a guide rod and a sliding box; and a lubricating mechanism is arranged in the sliding box. By arranging the driving mechanism, compared with a traditional pile driver which pulls a pile hammer through a steel wire rope for striking, the pile driver can drive the pile hammer to repeatedly and rapidly hammer timber piles through a motor, and the pile driving efficiency is greatly improved; and by arranging the lubricating mechanism, the lubricating mechanism is driven to discharge oil while the driving mechanism operates, thus, the driving mechanism operates more smoothly, and equipment is prevented from being disassembled and lubricated.

Description

technical field [0001] The invention relates to the technical field of construction site equipment, in particular to a pile driver for a construction site. Background technique [0002] The pile driver is composed of pile hammer, pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) at the front of the pile frame, and is hoisted with a lifting hook. The pile frame is a steel structure tower frame, and a hoist is provided at the rear of it for lifting piles and pile hammers. There is a guide frame composed of two guide rods in front of the pile frame, which is used to control the direction of pile driving, so that the pile can accurately penetrate into the ground according to the design orientation, and wooden pile support is widely used in water conservancy, bridges, and shallow foundation pits of buildings. When driving wooden piles, it is advisable to drive the wooden piles one by one to a stab...
