Intelligent electrical control system and control method for screw pile machine

Abstract

The invention relates to an intelligent electrical control system and a control method of a screw pile machine. The screw pile machine is connected with a photoelectric coder, a travel switch and a tension sensor of an electronic control system to realize detection feedback, and the feedback is subjected to programming treatment in the electronic control system so that coordinated operation of a hoist motor, a backpressure motor, a variable-frequency motor I and a variable-frequency motor II can be synchronously controlled in a variable-frequency control mode, and thus the relative relation between the rotating speed of a threaded drill pipe and the rotating speed of the hoist motor can be regulated continuously; therefore, influences of human adverse factors can be reduced, the labor intensity can be alleviated, internal threads which are formed are good in quality, the drilling quality is stable, the construction efficiency is high, the fault rate of a driving device is low, and convenience is provided for maintenance; after a wireless communication module has connection with a pump truck, construction parameters can be conveniently recorded and invoked, so effective supervision is realized, and engineering problems can be found in time and remedied in time as well so as to eliminate hidden dangers of the engineering; and after the intelligent electrical control system is connected with a network cloud system, remote supervision and maintenance can be performed conveniently, and construction history records can be queried conveniently.

Description

technical field [0001] The invention relates to the field of engineering construction machinery, in particular to an intelligent electrical control system of a screw pile machine and a control method based on the intelligent electrical control system. Background technique [0002] Modern roads, railways, multi-storey or high-rise buildings all require strict foundation treatment and appropriate load-bearing pile foundations to carry buildings and prevent damage to buildings caused by earthquakes. Generally, prefabricated piles and cast-in-situ piles can be used as load-bearing pile foundations. However, prefabricated piles can only be prefabricated with pile foundations of appropriate length, and then docked according to actual needs. The butt piles have very little lateral bearing capacity for the pile body, and are often easily misplaced. They only have vertical bearing capacity, and the piling docking process takes time and effort. materials, the cost is high. [0003] ...
