Control system for attached vibrator used for shield segment concrete vibration

Abstract

The invention provides a control system for an attached vibrator used for shield segment concrete vibration. The control system for the attached vibrator used for shield segment concrete vibration comprises a power distribution cabinet, a PLC central processing unit, an input module, an output module, a communication module, an upper computer, a control button, a sensor, a signal indicator light and a pneumatic circuit. The input module provides a sensor signal and a button signal for the central processing unit. The output module executes an output signal of the central processing unit to drive all systems of the pneumatic circuit. Based on the PROFINET protocol, the upper computer interacts with the central processing unit through a communication module. According to the control system for the attached vibrator, parameters such as the vibration frequency, the vibration time, the amplitude and the pneumatic pressure can be monitored and controlled in real time, programmed control overthe attached vibrator is achieved, the labor intensity is relieved, the vibration process can be controlled, and excessive vibration and insufficient vibration are effectively avoided; and concrete quality problems such as bubbles, holes, honeycombs and pitted surfaces of shield segments are eliminated, and the concrete construction quality of the shield segments is ensured.

Description

technical field [0001] The invention relates to an attached vibrator control system, in particular to a vibrator for shield segment concrete and belongs to the field of shield segment concrete construction. Background technique [0002] In recent years, domestic subway construction projects have developed rapidly, and the main components of subway tunnels in shield tunneling construction include reinforced concrete lining segments for subway tunnels, that is, shield segments; the quality of subway shield segments is directly related to the physical quality of subway tunnels . In the production and construction of shield tunneling segments, the concrete vibrating process is the most critical link in the production and construction of shield tunneling segments, which is directly related to the physical and appearance quality of the shield tunneling segments such as compactness, flatness, and air bubbles. Therefore, it is very important to control the vibration quality of shie...

Problems solved by technology

[0004] At present, the traditional attached vibrator mostly uses a pneumatic circuit to directly drive the attached vibrator to vibrate concrete. This method is extensive in construction, high in labor intensity, and parameters such as vibration frequency, vibration time, pneumatic pressure, and amplitude cannot Monitoring, the concrete vibrating process is uncontrollable, prone to over-vibration, under-vibration, and cause quality problems such as air bubbles, cavities, honeycombs, and pockmarks on the surface of the segment. The proficiency and responsibility of the workers directly affect the quality of concrete vibration, which is difficult to guarantee Construction quality of shield segment concrete
