Embodiment 1

[0039] Example 1, such as figure 1 As shown, a shield muck improvement control device based on muck monitoring, including automatic manipulator I1 and automatic manipulator II (same structure as automatic manipulator I1, figure 1 Not shown in), the automatic mechanical arm I1 is used to control the up and down movement of the stirring device 9, and the automatic mechanical arm II is used to control the up and down movement of the grasping container 8, so as to collect the muck. The end of the automatic mechanical arm II is connected with a grasping container 8 for collecting muck, and the grabbing container 8 is arranged directly above the belt conveyor 10 for transporting the muck to facilitate the collection of the muck transported on the belt conveyor 10. The end of the automatic mechanical arm I1 is connected with a stirring device 9 for stirring and grabbing the muck in the container 8 , and the agitating device 9 is arranged in the grabbing container 8 to stir the muck i...

Embodiment 2

[0044] Embodiment 2, a kind of shield dregs improvement control method based on dregs monitoring, such as figure 2 As shown, the steps are as follows:

[0045] Step 1: The shield machine starts to excavate, and the host computer obtains the slag discharge information and gives control instructions to the slag improvement control device, so that the moisture sensor 11, torque sensor 4, force sensor 2 and load cell 6 all start to work. At the same time, the geological exploration data of the muck soil in the current excavation interval are retrieved to obtain the water content interval of the current muck soil [ω min , ω max ] and shear strength interval [s min ,s max ]; where, ω min is the minimum water content, ω max is the maximum water content, s min is the minimum shear strength of muck, s max is the maximum shear strength of the muck. Force sensor 2 detects the weight of stirring device 9, and load cell 6 detects the quality of grasping container.

Abstract

The invention provides a shield muck improvement control device and a method based on muck monitoring. The device comprises an automatic mechanical arm I and an automatic mechanical arm II, the end part of the automatic mechanical arm II is connected with a grabbing container for collecting muck, the grabbing container is arranged above a belt conveyor for conveying the muck, the end part of the automatic mechanical arm I is connected with a stirring device for stirring the muck in the grabbing container, a moisture inductive sensor, a torque sensor which measures the stirred muck torque and a stress bearing sensor which measures the weight of the stirring device and the weight of the stirring device after the muck is attached are arranged on the stirring device, a weighing sensor which measures the weight of the grabbing container and the weight of the muck in the grabbing container is arranged on the grabbing container, the moisture inductive sensor, the torque sensor, the stress bearing sensor and the weighing sensor are all connected with a controller, and the controller is connected with an upper computer. The device has the real-time performance and quantitative performance of muck parameter monitoring, the structure is simple, intelligent sensing is achieved, the problem that muck improvement is not real-time can be effectively solved, and the muck output quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of shield machine dregs monitoring and dregs improvement, in particular to a shield dregs improvement control device and method based on dregs monitoring. Background technique [0002] The muck improvement is to inject the modifier into the cutter head, the soil bin and the screw conveyor, so that the muck cut by the cutter head of the shield machine has better flow plasticity and lower friction. On the one hand, the flow plasticity of the dregs determines the operation status of the shield machine, whether the dregs can be discharged smoothly, whether the cutter head is stuck, and the spewing of the screw conveyor; on the other hand, the improvement of the dregs directly affects the stratum Disturbance and facilitate the control of surface subsidence. Therefore, in the excavation process of earth pressure balance shield, muck improvement is an important technical link, and the effect of muck improvement de...
