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 present invention proposes a shield tunneling dregs improvement control device and method based on dregs monitoring. The device includes an automatic manipulator I and an automatic manipulator II. The end of the automatic manipulator II is connected with a grasping container for collecting dregs. The grabbing container is arranged above the belt conveyor for transporting the muck, and the end of the automatic mechanical arm I is connected with a stirring device for stirring the muck in the grabbing container, and the stirring device is provided with a moisture sensor and a torque sensor for measuring the torque of the muck And the force sensor for measuring the weight of the stirring device and the stirring device after the muck is attached, the grab container is equipped with a load cell for measuring the weight of the grab container and the muck inside, a moisture sensor, a torque sensor, a force sensor and a scale The heavy sensors are all connected with the controller, and the controller is connected with the upper computer. The present invention has the real-time performance and quantification of muck parameter monitoring, simple structure and intelligent perception, can effectively solve the problem of non-real-time improvement of dregs, and improve the output quality and efficiency of muck.

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...
