CONSTITUTION:A battery locamotive runs along a rail 2. In this case, a probing means 4 is connected at the front of the battery locamotive through a universal joint 1a and a supporting lever 1b, a wheel 4b being attached to a box 4a. The probing means 4 is constituted by at least any one of a rail cleaning device 5, a rail gauge measuring device 6 and a gas sensing device 7. The is when the battery locamotive runs along, a motor 5a is operated, thereby rotating a brush 5b, so that the rail 2 is cleaned. A pair of rollers 6b are brought in contact with the rail 2, so that the interval between these two is measured by a stroke meter 6c. And furthermore, the presence of any noxious gas is sensed by a sensing sensor 7a and oxygen concentration is sensed by a measuring instrument 7b.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail environment exploration device which is used when excavating a tunnel or the like and which confirms in advance the state of a rail on which a battery locomotive is traveling.

[0002]

2. Description of the Related Art Conventionally, each worker has carried out a cleaning work of a rail surface, a measurement of a distance between rails by a rail gauge, and an environmental investigation for the presence or absence of gas.

[0003]

However, the above-mentioned conventional cleaning work is complicated since it must be carried out after the locomotive is in operation or after passing through it, and the measurement of the rail-to-rail distance is a manual work.
As the tunnel becomes longer, the time required for measurement becomes longer, the measurement man-hours and cost increase, and there is a problem that the gas detection work is dangerous in the environment of harmful gas.

The present invention solves the above-mentioned problems, unmanned the rail cleaning work, confirms the distance between the traveling rails before the locomotive travels, or conducts an environmental survey in the tunnel before entering the tunnel. The purpose is to improve safety and work efficiency during tunnel excavation.

[0005]

In order to achieve the above object, the present invention provides a battery locomotive that travels on a rail by a guided radio path, and is provided with an exploration means, the exploration means being a rail cleaning device and a rail interval measurement. At least one of the apparatus and the gas detection and measurement apparatus is provided.

[0006]

[Function] The rail surface is cleaned by the cleaning device having the rotating brush of the exploration means provided in the battery locomotive traveling by wireless guidance, the rail-to-rail distance measuring device measures the rail-to-rail distance, and the gas detecting and measuring device measures toxic gas. Since the oxygen concentration is detected, safety can be achieved during excavation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a wireless control type battery locomotive,
The locomotive 1 travels unmanned on the traveling rail from the guidance signal from the guidance wireless path 3 parallel to the rail 2.

Reference numeral 4 denotes an exploring means, which is a universal joint 1a from the front of the battery locomotive 1, a substantially rectangular parallelepiped casing 4a connected by a supporting rod 1b, and the traveling rail 2 A rail cleaning device 5 that has wheels 4b that roll over and is driven by the battery locomotive 1 and that cleans the rail 2 in the front part of the housing 4a, and the distance between the rails 2 is measured. It is comprised of a rail interval measuring device 6 and a detection measuring device 7 for detecting toxic gas in the tunnel and measuring oxygen concentration.

The rail cleaning device 5 includes a motor 5
a and a brush 5b fixed to the rotating shaft of the motor 5a, the upper surface of the rail 2 is rotated to be cleaned.

Further, the rail distance measuring device 6 includes a roller 6b which abuts on the inside of the rail 2 by a pressing spring 6a,
6b and a stroke meter 6c for measuring the moving distance of the rollers 6b, 6b.

The detection / measurement device 7 is composed of, for example, a detection sensor 7a for detecting CO ₂ gas and the like, and an oxygen amount measuring device 7b for measuring the oxygen concentration.

Reference numeral 8 denotes an inductive wireless converter which transmits signals from the stroke meter 6c, the detection sensor 7a, and the oxygen content measuring device 7b to a central processing unit 9 on the ground through the inductive wireless path 3. Send.

Reference numeral 10 denotes a display device, which comprises an image display monitor 10a, and the central processing unit 9
The position of the rail 2 that needs to be adjusted, the presence or absence of gas, and the oxygen concentration are displayed by the signal from.

Next, the operation of the embodiment having the above construction will be described.

When the battery locomotive 1 is transmitted, the motor 5a of the rail cleaning device 5 operates and the brush 5b rotates to clean the rail 2.

The roller 6 of the rail distance measuring device 6
b and 6b come into contact with the rail 2 and the distance between them is detected by the stroke meter 6c, and is input to the central processing unit 9 by the inductive wireless converter 8 via the inductive wireless path 3.

The presence / absence of toxic gas by the detection sensor 7a and the oxygen concentration by the oxygen amount measuring device 7b are determined by the inductive wireless converter 8 via the inductive wireless path 3 and the central processing unit 9 is operated.
Entered in.

Thus, the current position of the battery locomotive 1, the measured value of the stroke meter 6c, the presence or absence of toxic gas, and the oxygen concentration calculated by the central processing unit 9 are displayed on the image display monitor 10a.

The exploration means 4 is replaced by the battery locomotive 1
It can also be formed at the rear of the vehicle or integrally with the battery locomotive 1.

[0021]

As described above, according to the present invention, the rail cleaning device, the rail interval measuring device, or the gas detecting / measuring device provided in the exploration means provided in the battery locomotive traveling on the rail by the guide wireless path, Rail cleaning work can be unmanned, the distance between running rails on which locomotives run can be checked, or the environment inside the tunnel can be checked before entering the pit, thus improving safety and improving work efficiency during tunnel excavation.
