Walking pile driver chassis and walking pile driver including the chassis

Abstract

The invention provides a walking pile driver chassis and a walking pile driver comprising the same. The chassis at least comprises a support plate (13), hydraulic cylinders (1), and steel I-beams or channel beams (8). The support plate (13) is fixedly connected with a walking pile driver chassis platform (3). A cylinder block of every hydraulic cylinder (1) is connected with the support plate (13). The steel I-beams or channel beams (8) are arranged on two sides of the walking pile driver chassis platform (3). The hydraulic cylinders (1) are disposed on the inner side of a side steel beam (8) of the chassis platform. A piton rod of every hydraulic cylinder (1) faces to space below the chassis platform (3). Side seal plates (61) are welded to open ends of the steel I-beams or channel beams (8). The chassis and the pile driver with the same have the advantages that bearing capacity is higher, connection is more stable, the pile driver is safer and more reliable to use, the transverse central distance of the cylinders is reduced, strength of the platform is improved, demounting hydraulic support legs is not required during transporting, transporting is more facilitated, the pile driver can be more efficiently installed on a work site, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of walking pile drivers, in particular to a chassis of the walking pile driver. The invention also relates to a walking pile driver. Background technique [0002] Pile driver is a prefabricated pile and cast-in-situ pile hole-forming equipment with multiple functions, high efficiency and low pollution. It is widely used in foundation construction projects such as municipal construction, highway bridges, and high-rise buildings. With different working devices, the pile driver is suitable for hole-forming operations in various working conditions, and is suitable for the soil geological conditions in most areas of our country, and has a very wide range of applications. Pile drivers mainly include walking pile drivers and crawler pile drivers. The crawler chassis has the characteristics of large driving force, good versatility, and strong adaptability, and can travel with a load. The walking pile driver adop...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the hydraulic outriggers of the walking pile driver are installed in a suspended manner. The hydraulic cylinder is connected to the side longitudinal beam of the walking pile driver platform through bolts, which increases the width of the platform. During the transfer, it needs to be disassembled Drop the oil cylinder and mounting seat, otherwise it will be super wide, and its strength will be easily affected by bolt connection, and there will be technical problems of poor safety and reliability during use

The center of gravity of the walking pile driver moves down, which is beneficial to improve the stability of the whole machine, but in the prior art, the walking trolley device of the walking pile driver occupies a relatively high position space, which is not conducive to reducing the height of the center of gravity
