Automatic hole punching piling machine control system aiming at complicated terrains

Abstract

The invention discloses an automatic hole punching piling machine control system aiming at complicated terrains, and belongs to the field of building engineering. The automatic hole punching piling machine control system consists of a power distribution cabinet (1), a control cabinet (2), an air compressor (3), a windlass (4), a brake air cylinder (5), a brake operation rod (6), a clutch air cylinder (7), a clutch operation rod (8), an air pipe (9), a height sensor (10), a clamp hammer sensor (11), a pile frame (12) and a pile hammer (13), and is characterized by also comprising a FFT (fast Fourier transform algorithm) conversion system, an excessive rope optimum control algorithm system and an excessive rope expert control system. The automatic hole punching piling machine control system has the advantages that the flexible response to various geological conditions can be realized, in addition, the reliability and the stability of the system are improved, meanwhile, the hammer lifting signal collecting speed is also accelerated, and the operation time of a microcontroller is reduced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an automatic punching pile driver control system for complex terrain. Background technique [0002] The traditional punching pile driver is composed of hoist, brake control, clutch control lever, pile frame, pile hammer and auxiliary equipment, etc., and generally requires manual operation. During the working process, the construction personnel control the hoist to lift and lower the pile hammer by frequently and repeatedly operating the clutch and brake operating levers. Use the impact force generated by the free fall of the pile hammer to periodically impact and break the target foundation until a pile hole with a certain depth and diameter is formed. During the punching process, use the slag pump to clean the debris in the hole in time In order to speed up the punching speed, after the punching is completed, the steel cage installation and concrete pouring are carried ...

AI Technical Summary

Problems solved by technology

[0003] At the same time, in the piling process of the traditional pneumatic punching pile driver, when the pile hammer hits the bottom of the pile with its own gravity, due to the inertia of the pile hammer, the winding device will be driven to rotate at an accelerated speed. If the winding device cannot be braked in time, The wire rope will fall endlessly due to inertia, and the subsequent clutch time will cause the length of the remaining rope to be too long

The length of the remaining rope is too long, which not only reduces the efficiency of the piling system, but also because the pile hammer is deposited at the bottom of the pile for a long time, it is easy to cause failures such as suction hammer and hammer jamming, which poses a great safety hazard

However, if the brake is too early, the remaining rope will be too...
