Pure mechanical building pile driver

Abstract

The invention discloses a pure mechanical building pile driver. The pure mechanical building pile driver comprises bases. The upper ends of the bases are connected with bearings. The upper ends of the bearings are connected with lead screws. Driven wheels are connected to the middle portions of the lead screws. The driven wheels are engaged with drive wheels. Rotation handles are connected to the drive wheels. The upper ends of the lead screws are connected with sliding blocks. The lower ends of the sliding blocks are connected with telescopic springs. The upper ends of the sliding blocks are connected with supporting rods. The middle portions of the supporting rods are connected with fixing rods. Motor shafts are arranged at the middle portions of the fixing rods and connected with rotation wheels. The outer sides of the rotation wheels are connected with gear tooth sets. A beam is connected to the upper ends of the supporting rods. The lower end of the beam is connected with a buffering spring. An annular limiting sleeve is arranged on the outer side of the upper end of the buffering spring. The lower end of the buffering spring is connected with a pile driving rod. The bottom end of the pile driving rod is connected with a pile cone. By means of the pure mechanical building pile driver, constant ascending and descending on a pile hammer are achieved, and therefore the pile body driving function is achieved; usage of a hydraulic system is avoided, and the manufacturing and maintaining cost is greatly reduced; and meanwhile, pollution is small, and energy saving and environment-friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of construction pile drivers, in particular to a purely mechanical construction pile driver. 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 designed orientation. The basic technical parameters of the pile driver are the impact part weight, impact kinetic energy and impact frequency. Pile hammers can be divided into drop hammers, steam hammers, diesel ha...
