2. Description of the Related Art A roller coaster travels in all directions of 360 degrees on a vertical plane including vertical, reverse rotation and diagonal traveling and a plane orthogonal to it, according to its traveling rail. This traveling rail and its supporting structure are inspected mainly by a person walking near a traveling path installed near the traveling rail.

As an apparatus for traveling at low speed on a traveling rail of a roller coaster, there is an apparatus disclosed in Japanese Patent Laid-Open No. 9-248385. Although this device is not an inspection vehicle, it is a towing vehicle for performing a running test of a roller coaster at low speed, equipped with a caterpillar to which a permanent magnet is attached, and travels in close contact with a rail by the permanent magnet. The traveling is performed by driving a motor with a battery mounted on the towing vehicle.

However, the above-mentioned manual inspection requires a long time for the inspection and also requires a lot of work at a high place, so that there is a problem in safety.

Further, the device disclosed in Japanese Patent Laid-Open No. 9-248385 may cause slippage during vertical traveling. The causes of slippage include reduction of frictional force when the rail surface gets wet due to rain or the like and increase of weight of the towing vehicle due to use of the battery. As a method of reducing weight, there is a method of using an internal combustion engine instead of a battery and a motor, but it has an output that makes an inspection vehicle of several hundred kg or more self-propelled,
Also, in commercially available internal combustion engines, the inclination of the posture that can be operated steadily is only about 15 degrees, and if it is more than that, seizure etc. occurs due to lack of lubricating oil,
There is a problem that steady operation cannot be performed.

An object of the present invention is to use a commercially available internal combustion engine as a power source, to make a self-propelled movement in all directions of 360 degrees in a vertical plane and a horizontal plane, and inspect a rail and a rail support structure for a roller coaster. And to provide an inspection system using the same.

The operating state data signal and the inspection data signal are sent to each device of the fixed base by the reverse route of reception, and the operating state of the inspection vehicle 1 is grasped, the traveling rail 2 and the rail structure 3 are provided.
It is used for inspection.

The present invention relates to the drive unit of the inspection vehicle 1, which will be described below. Inspection vehicle 1 is trolley 1
0, an inner car 15, internal combustion engines 16a, 16b, bevel gears 7a, 7b, drive shafts 8a, 8b, 9a, 9b, 26a, 26b, an inspection device 20, an outer car 21, and the like.

Wheels 11a, 11b and 11c are attached to the carriage 10 at four positions. Wheel 11a has a rail surface on the dolly side, wheel 11b has a rail surface opposite to the dolly, and wheel 11c has a structure capable of running on the side surface of the rail. The traveling vehicle 1 can be held on the traveling rail 2 in all directions.

Inside the inner car 15, a mobile wireless device 18a which receives an operation signal from the mobile wireless device 18b, transmits an operation state signal and sends / receives a signal to / from the internal combustion engine control device 17, and generates power 2 One internal combustion engine 16a, 16b and an internal combustion engine control device 17 that receives an operation signal to start / stop the internal combustion engine 16a, 16b and control the speed are installed.

The power of the internal combustion engines 16a, 16b is transmitted to the power converter 19 by the bevel gears 7a, 7b which are driving means and the drive shafts 8a, 8b, 9a, 9b, 26a, 26b. In the power conversion device 19, the powers having different rotational directions transmitted from the drive shafts 26a and 26b are added together, and the rotational direction of the power is converted by a forward or reverse drive signal and transmitted to the pinion 12.

The rack 13 installed on the rail support structure 3 and the pinion 12 mesh with each other, and the power transmitted to the pinion 12 allows the inspection vehicle 1 to run independently. In order to ensure the meshing of the rack 13 and the pinion 12, a rack guide roller 14 that presses the rack surface opposite to the meshing side of the rack 13 and the pinion 12 is attached to the power conversion device 19.

The internal combustion engines 16a and 16b are installed inside the inner car 15, the inner car 15 is supported by the outer car 21, and the outer car 21 is a trolley.
Backed by 10.

Drive shafts 8a and 8b are provided on the rotating shaft of the inner car 15, and bearings 22a and 22b of the drive shafts 8a and 8b are supported by the inner car 15.
The bearings 23a and 23b are supported by the outer cage 21. The drive shafts 9a, 9b that are also the rotation shafts of the outer car 21 are driven by the drive shafts 8a, 8b of the inner car 15.
The drive shafts 9a and 9b are installed in a direction perpendicular to the direction of the above, and are supported by bearings 24a and 24b installed in the outer car 21 and bearings 25a and 25b installed in the carriage 10.

The drive shafts 8a, 8b which are also the rotation shafts of the inner car 15 and the drive shafts 9a, 9b which are also the rotation shafts of the outer car 21 do not have to be on the same plane, but the internal combustion engine 16a, 16b, the internal combustion engine control device 17 and the mobile radio device 18a must maintain a right and left, front and rear weight balance so that the devices can maintain a normal posture, and the center of gravity G should be below the rotation axis. Constitute. The larger the distance between the center of gravity and the rotation axis, the easier it is to maintain a normal posture.

The internal combustion engines 16a and 16b have the same specifications, and the rotation directions when installed in the inner car 15 are opposite to each other, so that the reaction force due to the rotation is offset.
Therefore, the reaction force for rotating the inner car 15 is not generated by the startup, output change, and stop of the internal combustion engines 16a, 16b.

The running of the inspection vehicle 1 is on a plane orthogonal to the rotation axis of the outer car 21, but when the running of the inspection vehicle 1 has a three-dimensional azimuth with an inclination, the center of gravity G of the outer car 21 is the rotation axis. Since it is below, the original posture can always be maintained with respect to changes in the plane orthogonal to the rotation axis of the outer car 21, but the original posture is maintained with changes in the rotation axis direction of the outer car 21. You cannot do it.

However, according to the embodiment of the present invention, which is composed of the outer car 21 and the inner car 15, the inner car 15 has the rotation axis of the inner car 15 with respect to the change of the rotation axis direction of the outer car 21. Outside basket 21
Since the center of gravity G of the inner car 15 is below the axis of rotation because it is located in the direction perpendicular to the direction of the axis of rotation of the Can maintain their posture.

An internal combustion engine installed in the inner car 15
The drive power is transmitted from 16a, 16b to the outer car 21 by the rotation of the drive shaft, but the inner car supported by the outer car 21
Since the rotating shaft of 15 and the drive shaft coincide with each other, and the rotation speed of the drive shaft is sufficiently higher than the pendulum motion speed of the inner car, power can be transmitted from the inner car 15 to the carriage 10.

As described above, with respect to the inclination of the traveling rail 2 to the left, right, front and rear, the inner cage 15 of the inspection vehicle 1 and the internal combustion engines 16a, 16b and the like built therein are always in a normal posture by the above supporting mechanism. Internal combustion engine 16a, 16
b can operate normally.

[0033]

According to the present invention, it is possible to provide an inspection vehicle for a roller coaster which can be self-propelled in all directions of 360 degrees in a vertical plane and a horizontal plane by using a commercially available internal combustion engine as a power source. The efficiency of the inspection work can be significantly improved, and the safety of the work can be secured.

Since a commercially available internal combustion engine can be used, the cost of the inspection vehicle for the roller coaster can be reduced.
