Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment, and in particular to a double-shield coal mine tunneling machine. Background Technology

[0002] Coal is an important energy source for industrial development and a strategic resource related to the security of national economic construction. The healthy development of the coal industry is inseparable from the safety and stability of coal mining. With the continuous increase in my country's total economic output, the demand for coal from all walks of life is increasing, and the pressure on the coal mining industry is also increasing day by day. As an important piece of equipment in the field of coal mining, the application of coal mine tunneling machines is becoming more and more widespread.

[0003] Chinese patent CN218912873U discloses a double-shield coal mine tunneling machine, including a main body. A climbing ladder is provided on the left front end of the main body. A drive unit and a counterweight are provided at the lower end of the main body. The counterweight is located to the right of the drive unit and is not in contact with it. A control room and a protective mechanism are fixedly connected to the upper end of the main body. A control console is provided on the left lower wall of the control room, and a seat is provided on the right lower wall of the control room. The control console and the seat are not in contact. However, the protective mechanism of the double-shield coal mine tunneling machine in the above patent cannot be detached from the tunneling machine. In the event of a mine collapse, it can only provide fixed-point support and cannot detach from the shield for evacuation, which reduces the safety of workers. Therefore, we propose a double-shield coal mine tunneling machine to solve the above problems. Utility Model Content

[0004] This utility model provides a double-shield coal mine tunneling machine. The first shield can protect the cab of the tunneling machine body, and the second cylinder can push the second shield to support the mine tunnel, achieving the effect of double protection for the tunneling machine body. Through the cooperation of the second cylinder and the anti-slip seat, the second shield can be smoothly detached from the tunneling machine body, achieving the effect of independent support for the mine tunnel, enabling the tunneling machine body to be smoothly withdrawn, and improving the safety of the workers.
