Walking pile frame

Abstract

The invention discloses a walking pile frame. The walking pile frame comprises a walking chassis, a machine body, an upright post and two pairs of inclined support rods, wherein the walking chassis comprises front and back traverse mechanisms and left and right longitudinal rotary mechanisms; the machine body are supported on the traverse mechanisms and the longitudinal rotary mechanisms by virtueof a plurality of groups of support legs; the lower end of the upright post is hinged to the front end of the machine body; the two pairs of inclined support rods are respectively connected between the upright post and the machine body so as to form two groups of symmetrical triangular support structures; and a winch unit, a hydraulic power station for driving the winch unit and a pile frame power system for driving the traverse mechanisms and the longitudinal rotary mechanisms are arranged on the machine body, and a steel wire rope connected with the winch unit bypasses a traction hoisting and drilling device on the top of the upright post by virtue of a pulley block. The walking pile frame has the advantages of high adaptability to construction site conditions, good stability during operation and high working efficiency of the whole machine.

Description

technical field [0001] The invention relates to a building construction machine, in particular to a crawler pile frame capable of suspending and installing foundation construction machines such as pile drivers and drilling machines. Background technique [0002] Pile frame is an indispensable mechanical equipment in building foundation construction. Various foundation construction machines such as pile drivers and drilling machines must be suspended and installed on pile frames for construction; walking pile frames are all kinds of pile frames. One of them, it moves in a step-by-step manner, and has the characteristics of safety and stability, so it is widely used in building foundation construction. [0003] The walking pile frame mainly includes a walking chassis, a fuselage, a hoisting unit, a column, a diagonal support and a power system, etc., and the chassis is composed of a lateral movement mechanism and a longitudinal movement and slewing mechanism. Its advantages a...

Problems solved by technology

[0007] (1) When the length of the column reaches a certain level, its rigidity will decrease significantly, its stability against compression will also be greatly reduced, and the axial bearing capacity of the entire column will also be greatly reduced, thus seriously affecting the performance of the whole machine;

[0008] (2) For the longitudinal movement and rotation mechanism in the chassis of the existing walking pile frame, its reset mechanism only has two groups at most, such as the Chinese patent document whose application number is 200710040925.9, which discloses a shoe reset mechanism for a piling frame If two groups are arranged on the longitudinal movement and slewing mechanism, then only one reset mechanism can work when turning and resetting, so the resetting force is limited and not symmetrical, so the resetting speed and reliability still need to be improved
