Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control system for a towing vehicle that enables remote control of a towing vehicle that pulls a truck for carrying materials and the like in shield work.

[0002]

2. Description of the Related Art In a shield work, a vertical shaft is excavated, a tunnel (horizontal shaft) is excavated laterally from the lower part of the vertical shaft, and a track of a truck and its towing vehicle is formed in the vertical shaft to transport materials and the like in the tunnel. To the face of the tunnel. Conventionally, regarding the operation of the towing vehicle, as shown in FIG.
Unmanned operation by guided radio is performed in the section from the tunnel entrance to the trailing tail of the trailing carriage, and from the end of the shaft to the tunnel entrance (hereinafter referred to as the shaft section), and from the trailing tail of the trailing carriage to the cutting face. Section of 60-100m (hereinafter,
The manned radio operation is performed by handy radio with a maximum communication capacity of about 20 m.
The reason why the inductive radio system is not used in the vertical shaft section or the face section is that the towing vehicle may run away. In order to perform manned wireless operation in the vertical section or the face section, the tunnel pit and the succeeding bogie shown in FIG. After temporarily stopping the towing vehicle at the end of, the worker confirmed the safety and then operated by manned radio.

[0003]

However, in the operation of the conventional towing vehicle, since the face section operated by the handy radio for manned operation is as long as about 60 to 100 m, a worker is required to reach the vicinity of the towing vehicle which is temporarily stopped. There was a problem in that the driver had to be greeted and the driving work was very troublesome, and the towing vehicle could not be smoothly driven from the unmanned driving section by the guide radio. Further, since the maximum communication capacity of the handy radio is about 20 m, there is a problem that the work of extending the guide radio in the unmanned driving section must be performed every day.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to improve work efficiency by eliminating the trouble of a worker welcoming him to a guidance wireless stop position where the towing vehicle temporarily stops. Another object of the present invention is to provide a remote control system for a towing vehicle in shield work that can be remotely operated on the ground or in a tunnel without the need for daily extension work of induction radio.

[0005]

In order to achieve the above-mentioned object, the present invention provides a towing vehicle including a traveling drive unit and a drive control unit, which is connected to a trolley, from a ground in a guiding radio section from a tunnel mouth to a face. In the shield construction to be operated unmanned by the guide radio, the towing vehicle is provided with an antenna connected to the drive control unit, and an antenna is provided at a position other than the guide radio section in the tunnel and a modem is used for the antenna. A remote control panel connected to the vehicle is installed, and the towing vehicle is remotely controlled via the both antennas by operating the remote control panel in a section other than the guidance wireless section.

Further, the present invention is characterized in that the antenna, the modem and the remote control panel are installed near a face of a tunnel and inside a shaft, respectively. Further, in the present invention, while the imaging device is installed on the towing vehicle, a remote operation panel and a monitor for displaying an image by the imaging device are installed on the ground, and the modem is connected to the remote operation panel on the ground through a cable. By operating a remote control panel on the ground while looking at the screen of the monitor from the ground, the towing vehicle is remotely controlled in a section other than the guidance wireless section.

[0007]

In the guidance radio section, the towing vehicle is automatically driven by the guidance radio from the ground as in the conventional case. In sections other than the guided radio section, such as sections up to the face and sections in the shaft, remote operation is performed through the towing vehicle and both antennas provided in each section by operating the remote control panel installed respectively. The car is driven unmanned. Further, instead of the remote control panel installed in the tunnel, the remote control panel installed on the ground is operated while watching the monitor on the ground, whereby the towing vehicle is remotely controlled.
