Embodiment 1

[0048] like figure 1 As shown, the present invention is a real-time weighing system for shield tunnel engineering dregs, including a weighing device 5, a data acquisition device 11, a wireless transmission device 6 and a power supply device 12 arranged under the dregs hopper 41 of the muck truck 4 , and the data processing and display device 8 arranged in the shield machine operating room, the weighing device 5 weighs the muck, the data acquisition device 11 obtains the weighing signal of the weighing device 5, and wirelessly The transmission device 6 transmits the data to the data processing and display device 8 , the data processing and display device 8 processes the data and displays it in real time, and the power supply device 12 is used to supply power to the weighing device 5 , the data acquisition device 11 and the wireless transmission device 6 .

[0049] The weighing device 5 includes a weighing platform 51 between the slag hopper 41 and the mobile trolley 42, and a s...

Embodiment 2

[0059] like Figure 5 As shown, the present invention also discloses a method of using a real-time weighing system for shield tunnel engineering dregs, including any one of the above-mentioned real-time weighing systems for shield tunnel engineering dregs, and the usage method is as follows:

[0060] Step 1: Load slag, put the slag excavated from the excavated tunnel into the slag hopper. The excavated slag can be directly loaded into the slag hopper, or loaded into the slag hopper through a screw conveyor.

[0061] Step 2: Weighing. After the muck is full, trigger the weighing device to automatically weigh. The sensors installed on the left weighing platform and the right weighing platform respectively weigh the muck weight.

[0062] Step 3: signal collection and transmission, the data collection device obtains the weighing signal of the weighing device, and transmits the data to the data processing and display device through the wireless transmission device. Wherein, the ...

Abstract

The present invention discloses a shield tunnel engineering slag real-time weighing system and an application method thereof. The real-time weighing system comprises a weighing device, a data collection device, a wireless transmission device and a power device which are arranged below a slag hopper of a slag car, and a data processing display device arranged at a shield tunneling machine operationroom. The weighing device is configured to perform weighing of slag, the data collection device is configured to obtain weighing signals of the weighing device and transmit the data to the data processing and display device through the wireless transmission device, the data processing and display device is configured to perform processing and real-time display of the data, the power device is configured to supply power to the weighing device, the data collection device and the wireless transmission device. The application method comprises the steps of: filling slag into the slag hopper; triggering the weighing device to automatically perform weighing; obtaining the weighing signals of the weighing device through the data collection device, and transmitting the data to the processing and display device; and after the data processing and display device receives the weighing signals, converting the received weighing signals to figures, and displaying the figures on the display device.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a real-time weighing system for shield tunnel engineering dregs and a method for using it. Background technique [0002] With the large-scale development of infrastructure construction in our country, the shield tunneling method has gradually become the main construction method of tunnel engineering, especially in the construction of subway tunnels, road tunnels, and power tunnels in the core areas of cities. As the main equipment of shield tunneling method, earth pressure balance shield has been widely used in urban shield tunnel construction due to its good stratum adaptability and high cost performance. Excavation volume control is an important content in the construction management of earth pressure balance shield tunneling. The cutter head of the shield machine cuts the front soil, and the muck is sent to the muck truck soil box by the screw conveyor through the belt convey...
