Electric control system and electric control method for integrated pile driver drill pipe

Abstract

The invention relates to an electric control system of a comprehensive pile driver drill pipe and an electric control method thereof. The system and the method solve the problem that the automation degree of an existing pile driver is low. The system comprises a drill pipe assembly, a power head and a drill pile disassembly and assembly device, and the drill pipe assembly is provided with multiple drill pipe bodies. The drill pipe disassembly and assembly device is provided with a disassembly and assembly driver. The power head is connected with a drill pipe lifting mechanism provided with a plurality of lifting drivers. The power head, the disassembly and assembly driver and the lifting drivers are connected with a power source, and a first power adjusting device is disposed between the power source and the power head. A second power adjusting device is arranged between the power source and the lifting drivers. The drill pipe assembly is connected with an ash conveying system, an ash conveying control device is arranged between the drill pipe assembly and the ash conveying system, and the disassembly and assembly driver, the first power adjusting device, the second power adjusting device and the ash conveying control device are all connected with a PLC. The electric control system has the advantages that rotation and lifting speed of a drill pipe is controllable, ash conveying amount is controllable, and filling of drilled holes can be conducted in time.

Description

Technical field [0001] The invention belongs to the technical field of construction equipment, and in particular relates to an electric control system for a drill rod of a comprehensive pile driver and an electric control method thereof. Background technique [0002] At present, there are two types of piling machines used on construction sites: one is a rotary pile driver, which uses a drill rod suspension frame pulled up by a hoist to drill through the drill rod; the other is an impact hammer Pile driver, the structure of this type of pile driver is to use a hoist to pull the impact hammer repeatedly to fall and lift to achieve piling. Among them, the rotary pile driver mainly uses the circumferential rotation of the drill rod to achieve the purpose of drilling the rod underground. However, due to the long length of the drill rod during actual construction, there is a problem of inconvenience in installation and disassembly, and the fixed drill rod is installed The stability is...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned scheme solves the problem of poor stability of the drill pipe of the existing pile driver to a certain extent, but the scheme still exists: the joint between the drill pipe and the grouting mechanism is not convenient enough to disassemble, the degree of automation is low, and the drilled hole cannot be drilled.
