Abstract

The invention discloses a freely-adjustable supporting leg device for a pile driver. The device comprises a a hydraulic cylinder, a supporting leg, a bottom fixing seat, a worm, a worm gear and a driving motor, wherein the supporting leg is movably connected to the top end of a piston push rod at the lower part of the hydraulic cylinder and the supporting leg and the piston push rod can rotate relative to each other; a groove is formed in the middle of the bottom fixing seat; the lower portion of the supporting leg is movably fixed in the groove in the middle of the bottom fixing seat and freely rotates relative to the bottom fixing seat; the worm gear is fixedly connected to a rod body in the middle of the supporting leg in a sleeving mode; the worm and the worm gear are in transmission connection; and the end of the worm is in transmission connection with a rotating shaft of the driving motor. The freely-adjustable supporting leg device for the pile driver is simple in overall structure and capable of effectively realizing free rotation of the supporting leg, the automation degree is high, the labor intensity is low, the operation is simple and fast, and the practicability is high.

Description

Technical field: [0001] The invention relates to a freely adjustable outrigger device for a pile driver, and relates to the technical field of pile drivers. 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 hamme...
