Self-walking balance-weight-free static pile pressing device

Abstract

The invention belongs to the technical field of building devices and particularly relates to a self-walking balance-weight-free static pile pressing device. The self-walking balance-weight-free static pile pressing device is composed of a chassis, a clamping balance system, a pile pressing system and a moving system. The self-walking balance-weight-free static pile pressing device is characterized in that the clamping balance system is composed of locating oil cylinders and clamping plates which are arranged on the two sides of the bottom of the chassis, clamping of the clamping plates is controlled through the locating oil cylinders, the moving system is composed of a jacking oil cylinder arranged at the back end of the chassis, a moving oil cylinder and a moving guide rail, wherein the moving oil cylinder and the moving guide rail are arranged on the chassis, the pile pressing system is composed of a pile pressing frame, a guide rail frame, pile pressing clamps, a vibrating device and pile pressing oil cylinders, and the guide rail frame, the pile pressing clamps, the vibrating device and the pile pressing coil cylinders are fixed to the pile pressing frame. The self-walking balance-weight-free static pile pressing device has the advantages of being reasonable in design, convenient to use, convenient and flexible to operate, capable of accurately controlling the pile planting accuracy and improving work efficiency, safe, reliable, good in project quality, capable of having little influence on surrounds and surrounding buildings and free of damaging the earth structure.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, and in particular relates to a self-propelled static pile pressing device without counterweight. Background technique [0002] Pile driver is a commonly used equipment in construction engineering, which is a pile machine that uses static pressure to press piles into the ground. It is used for soft soil laminated piles, such as pile construction in underground railways, seaports, bridges, reservoir power stations, offshore oil production platforms and national defense projects. Existing pile driver is divided into two kinds of mechanical type and hydraulic type. [0003] When the mechanical pile driver is in operation, the pile is placed under the pressure beam, and the pile pressure pulleys are installed on both sides of the pressure beam. The steel wire rope is led out from the hoist, goes around the guide pulley on the top beam of the pile frame, and then goes around the movabl...

AI Technical Summary

Problems solved by technology

[0005] Both of the above two types of pile drivers are bulky and their own weight is hundreds of tons or even thousands of tons. When used, they need to occupy a large work site. The requirements for the construction site are extremely strict, and the pile planting speed is relatively slow. It is difficult to control the pile forming accuracy, and it is very inconvenient to transfer, disassemble and transport.
