However, the rail type carrier has a limited traveling speed, requires a lot of time from the wellhead to the face, and requires a long time before and after the carrier for a long time each time material is loaded and unloaded. Each person must have a worker, which greatly affects the overall process construction period. In addition, the tunnel is usually a single line because the tunnel cross section is small, and blind lines are provided at regular intervals on the way, where vehicles entering and exiting the tunnel cross each other, and each time the rail point is switched, an operator is required. You have to get out of the carrier and operate the switch.

When a steel car such as a trolley or a shear car is connected to the carrier, only one driver is required when the carrier is in front, but when the carrier is in the opposite direction, another driver is in front. Needed. Further, when rails are installed, there is an advantage that a passage can be secured, but it requires time and effort for removal when constructing the bottom plate, and there is also a risk of derailment or overturning during transportation work.

Furthermore, for safety reasons, the speed of the carrier cannot be increased, which causes a serious problem in the process. The present invention has been proposed in view of the above-mentioned problems of the prior art, and the purpose of the invention is to speed up the inside of the mine by unmanning and mechanization, and improve tunnel construction in terms of both process and safety. The point is to provide a carrier.

[0006]

In order to achieve the above-mentioned object, a conveying device for constructing a tunnel according to the present invention is a tire type electric carrier that travels on a concrete traveling path laid in the tunnel, and the same carrier. A vehicle guidance device that controls the vehicle so that it does not deviate from the prescribed operation route, and constantly monitors the operation status of the transport vehicle, displays information on the monitor in the observation room outside the mine, and transmits information to convey information inside the mine It is composed of a device and a safety device that senses an obstacle on the traveling path and issues an alarm to the carrier, and manages the operation of the carrier in the mine.

[0007]

According to the present invention, a tire-type electric carrier travels along a predetermined guide line on a concrete runway laid in a tunnel by a vehicle guiding device without deviating from a running route. In the case of unmanned operation, the road is maintained with a certain degree of accuracy, and the safety device is maintained, so that the vehicle can be operated at high speed.

[0008] The situation inside the mine is grasped by the information transmission device, and it does not collide with an obstacle on the road,
It enables efficient operation of the carrier.

[0009]

The present invention will be described below with reference to the illustrated embodiments. Fig. 1 shows the outline of this device, and 1 is an electric carrier for material transportation of a tire system, along a concrete running path 2 laid evenly on the bottom of the tunnel, along a guide cable 3 laid on the top of the tunnel. Run. Since the guide cable 3 is installed above the transport vehicle 1 in this manner, it is possible to drive the retractable antenna 4 upright during automatic operation so that the antenna 4 strongly receives the guide radio waves. Then, the steering wheel of the unmanned driving device is controlled, and the transport vehicle 1 moves along a prescribed trajectory on the traveling path 2. Further, if the antenna 4 is turned upside down, a manual operation becomes possible.

A bag line portion 5 is provided on the traveling path 2 every 500 m, and the bag line portion 5 is divided into two systems for both the traveling path 2 and the guide cable 3, and an empty line is confirmed near the branch portion. Signal is automatically switched by the sensor 6 installed on the side wall of the tunnel so that only an empty line is allowed to pass therethrough, and it is not necessary to get out of the car for operating the switch.

Always move along the guide line during unmanned driving,
Various operation modes can be selected by the operation panel mounted on the transport vehicle 1 when operating on a face or outside the mine, or when used as a person's car. For example, the driving route can be left to automatic guidance so that only the speed is changed to manual operation, or the vehicle can be completely driven out of the guide line.

At the time of manual driving, the steering wheel, accelerator and brake are operated in the same manner as an ordinary electric vehicle.
A qualified person drives. The speed control during unmanned operation is wirelessly instructed to the carrier by the central monitoring device 7 outside the mine through the optical communication cable 8 and the nearest repeater 9 installed every 500 m inside the mine.

As will be described later, this wireless device is also used as a communication means inside and outside the mine. During operation in the mine, it is completely under the control of the central monitoring device, and when changing it, it is done with permission, etc. to ensure safety. The optical communication cable 8 is guided from the central monitoring device 7 outside the mine into the mine,
It is connected to the cutting face via the repeater 9 installed in the deadline section 5 every 500 m.

The information connected to the cable is also used for the image information of the television monitor 10 installed at the face of the face, the key point in the mine, or the wellhead, and the security system, and the infrared transmission device 11 is installed in the carrier 1. Installation, each carrier 1
The current position of each transport vehicle 1 can be confirmed by reading the code number set for each with the receiver 12 installed near the repeater 9 every 500 m. Further, when an obstacle on the traveling path 2 is detected, the central monitoring device 7 issues an alarm to the carrier 1 to cause an emergency stop. Further, the personal computer 13 processes the data to form an operation management system, and the cable 8 is used as a communication line of the underground wireless communication device.
Since the underground radio has a communication capability of 500 m or more, it is possible to make mutual calls through the repeater 9 on all lines such as the face, the carrier, the pit, etc. Of the vacant route is sent to the central monitoring device 7 via the relay device 9.

When there is a request for permission to pass a train,
The central monitoring device 7 determines the passage route of the automatic driving device, and energizes the guide cable 3 on the passable route. Also,
It also conveys signal switching information. Further, by sending a command such as operation start, traveling speed, etc. to the automatic driving device and starting automatic operation, and by the command of the central monitoring device, the transport vehicle 1 completes the movement to the target position. In addition, underground environment measurement data such as temperature, humidity, oxygen concentration, carbon monoxide concentration, and dust amount measured by the environment measurement sensor 14 are transmitted to the central monitoring device 8 through the relay device 9, and the inverter device controls the blower Control the number of rotations to keep the ventilation volume optimal.

The polluted water, the amount of the polluted water, the concentration of the discharged water, the PH value, etc. are automatically measured and displayed on the monitor of the central monitoring unit 7 so that any trouble can be dealt with quickly. In addition, the data of loading and unloading of materials are sequentially communicated, and the progress of the work can be checked at a glance by the monitor, and the geological data of the current work position, information on the blasting work, etc. are displayed.

At the same time, information such as the current entry condition and work status is transmitted to the central monitoring device 8 and displayed on the monitor 15. Of the above information, the main information such as underground operation status, environmental conditions, work status, and entry name will also be displayed at the wellhead. Furthermore, a security device is configured by the traveling road obstacle detection device, the underground wireless system, the underground TV monitor system, the operation management system, and the environmental management system described above. When the carrier 1 travels in the underground, people, materials, etc. 3 obstacles
It senses 0 m or more in front, issues an alarm, stops, and returns to normal operation when the obstacles disappear within a certain time. Otherwise, it sends a signal to the central monitoring unit 8 to remove the obstacle.

The obstacle detection device for traveling roads uses a video camera to capture the path ahead of the traveling route, and when an object of a certain size or more is detected on the screen by the processing of the computer in the sensing area of the monitor screen, an electric transport vehicle. 1 to send a signal to activate the brake to stop the carrier 1. In this way, the safe running of the haul vehicle is maintained.

In addition, the underground radio system enables quick and reliable contact in an emergency and can also be used for normal business contact, thus contributing to work efficiency. By installing a TV monitor, the situation inside the mine can be constantly grasped outside the mine, and work meetings between the inside and outside the mine can be done not only by talking but also by video, so there are few mistakes.

The operation management system not only grasps the operation status of the vehicle in the mine, but also determines the priority when there is a counter vehicle, gives an instruction to wait on the deadline, or designates a designated section. Information such as running speed in
Trains can be instructed via the repeater 9. In addition, environmental measurement data can be centrally managed at all times, and in the event of abnormal conditions, it is possible to respond swiftly and reliably, and it is also possible to centrally manage mine entrance information and material import information.
