A slag stirring monitoring device and stirring detection method thereof

A technology of a monitoring device and a detection method, which is applied in the direction of earth drilling, mining equipment, tunnels, etc., can solve the problem of being unable to accurately understand the internal conditions of the excavation cabin in real time, and cannot intuitively judge the mud cake formed by large-sized foreign objects in the muck, which affects the excavation. To reduce the number of abnormal shutdowns, reduce the total time of cabin entry, and improve construction efficiency

Problems solved by technology

[0002] When using a roadheader for tunneling operations, when excavation is carried out under the condition of establishing a pressure balance between the excavation cabin and the face of the tunnel, the excavation cabin is in a closed state due to the existence of high pressure, and the operator cannot accurately unlock it in real time. The internal situation of the excavated cabin, including whether there are large-sized foreign objects, whether there is mud cake in the excavated cabin, the mixing of the dregs in the excavated cabin, and the improvement status of the dregs in the excavated cabin, etc., are greatly affected by the inability to monitor and update feedback in real time. It affects the tunneling efficiency and construction period of the roadheader, resulting in an increase in construction costs
[0003] In the published patent CN110849775A, a method for monitoring the viscosity of dregs in the excavation cabin is mentioned. The device and method mention that the viscosity of the dregs in the excavation cabin can be detected by sensors and displayed on the host computer interface in real time, but it cannot be visually judged. Whether there are large-sized foreign objects in the soil, whether there is mud cake in the excavation cabin, etc., and the formation of mud cake cannot be effectively prevented

Embodiment 3

[0042] Embodiment 3: A roadheader, including the muck mixing monitoring device described in Embodiment 2, used for monitoring the muck in the excavation cabin during tunnel excavation, so as to facilitate timely adjustment of the parameters of the modifier and ensure the excavation Machine efficient excavation. The high-pressure water system can be set on the rear matching trailer.

Embodiment 4

[0043] Embodiment 4: A stirring detection method of a slag stirring monitoring device, the steps are as follows:

[0044] S1: Set an active stirring rod on the back of the cutter head 1, and set a passive stirring rod on the rear bulkhead of the excavation cabin 4. The active stirring rod and the passive stirring rod are located on concentric circles with different diameters, and the active stirring rod and the passive stirring rod Stress sensors 501 are arranged on the rods; the stress sensors 501 are connected to the host computer, and a display module is connected to the host computer; the data measured by the stress sensors can be displayed in real time on the interface of the display module of the host computer;

[0045] S2: During the excavation process, the main drive 3 installed in the shield body 2 drives the cutter head 1 to rotate, and the active stirring rod and the passive stirring rod perform stirring detection on the muck in the excavation cabin 4; The stress mo...

Abstract

The invention discloses a muck stirring monitoring device and a stirring detection method thereof, which are located inside an excavation cabin and include an active stirring assembly and a passive stirring assembly, the active stirring assembly is fixed on the back of the cutterhead, and the passive stirring assembly is fixed on the excavation cabin On the rear bulkhead, the active stirring component and the passive stirring component are equipped with monitoring devices, and the monitoring devices are connected with the host computer. The active stirring assembly and the passive stirring assembly are arranged in the excavation chamber of the present invention, and the active stirring assembly and the passive stirring assembly are used together. By arranging a suitable trajectory and a number of active stirring rods and passive stirring rods, they are arranged at the same section in the middle of the excavation chamber , realize accurate, real-time, two-way monitoring of muck stress, and transmit the monitored stress value to the host computer interface for display, so that the dregs in the excavation chamber can be monitored in real time on the host computer.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a dregs stirring monitoring device capable of stirring dregs in an excavation cabin and a stirring detection method thereof. Background technique [0002] When using a roadheader for tunneling operations, when excavation is carried out under the condition of establishing a pressure balance between the excavation cabin and the face of the tunnel, the excavation cabin is in a closed state due to the existence of high pressure, and the operator cannot accurately unlock it in real time. The internal situation of the excavated cabin, including whether there are large-sized foreign objects, whether there is mud cake in the excavated cabin, the mixing of the dregs in the excavated cabin, and the improvement status of the dregs in the excavated cabin, etc., are greatly affected by the inability to monitor and update feedback in real time. It affects the tunneling efficiency and const...
