2. Description of the Related Art Conventionally, a monorail type traveling apparatus has been known which is designed to carry a load while traveling a traveling carriage along a monorail track. The application of the monorail type traveling device may be used as a monitoring device other than the transportation of such articles. For example, a monorail track is installed in a turbine room of a thermal power plant, and a traveling carriage equipped with a surveillance camera is mounted on the monorail. The turbine is run along a track to monitor the abnormality of the turbine.

In such a monorail type traveling device, generally, the monorail track has an I-shaped cross section, the drive wheels provided on the traveling carriage are on the upper surface of the monorail track, and the respective support rollers are on the side surfaces of the monorail track.

Since the layout is required, it is advantageous to allow the traveling carriage to travel in a narrower space in order to enhance the monitoring function.

However, in the above-mentioned conventional monorail type traveling device, since the traveling carriage holds the monorail track, a certain space in which the traveling carriage can travel is required around the monorail track, and the traveling track is Layout restrictions are often imposed. In particular, with a monorail type traveling device having a structure in which the drive motor greatly extends in the width direction of the traveling carriage, it becomes difficult to drive the traveling carriage in a narrow space, or the turning (curve) part of the monorail track is turned. Since it becomes difficult to provide a turning track having a small diameter, it may not be possible to lay out the running track so that the object can be effectively monitored.

Recently, there has also been proposed a device for mounting a chain member on a monorail track, and engaging a pinion mounted coaxially with a drive wheel with the chain member to enable vertical traveling of a traveling carriage. However, even in such a device, the traveling carriage tends to expand in the width direction because the above-described mechanism for vertical traveling is provided.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a monorail type traveling device capable of traveling on a narrow space or on a turning track (curve) having a relatively small diameter. Has an aim.

Next, the operation of the monorail type traveling device will be described.

When the motor 12 is driven in the monorail type traveling apparatus configured as described above, the rotational driving force is transmitted to the drive shaft 14 via the pulley 24, the drive belt 25 and the pulley 15. As a result, the drive roller 13 is rolled on the rail portion 3b of the rail 1. Then, in the horizontal track portion, the traveling carriage 10 travels along the rail 1 by the rolling of the drive roller 13.

In the uphill portion and the downhill portion, the traveling carriage 10 is driven by the chain 6 and the pinion 17. That is, the rotational driving force transmitted to the drive shaft 14 is further transmitted to the drive shaft 18 via the transmission gear 16 and the passive gear 20.
And the pinion 17 is rotated while meshing with the chain 6, whereby the traveling carriage 10 travels along the rail 1.

Therefore, the drive roller 13 alone enables traveling on a steeply inclined track or a vertical track that causes slip, so that the traveling carriage 10 can travel from the horizontal track to the inclined track or the vertical track. Has become.

Then, while the traveling carriage 10 is traveling in this way, an image of the object is taken by the monitoring camera 30 and the taken image data is transmitted and output to the monitoring room or the like. The object in the monitoring room is remotely monitored by the operator.

By the way, the above monorail type traveling apparatus having the above-mentioned structure has the following advantages.

First, in the traveling vehicle 10, the traveling vehicle 10 is provided by arranging the motor 12, the mechanism portion for inclining and traveling on the vertical track, that is, the chain 6 and the pinion 17 under the rail 1. The lateral projection of the is suppressed, and as a result, the mounting part on the rail 1 has a compact structure, so when traveling in a narrow space or traveling on a turning track (curve),
The sideward projecting portion of the motor 12 or the like does not interfere with traveling. Therefore, the traveling carriage 10 can be made to travel in a narrower space or can be made to travel along a turning path having a small turning diameter.

Moreover, as the monorail track, a rail 1 having an I-shaped cross section having rail portions 3a and 3b at the upper and lower ends of the rail-constituting wall 2 is applied, and the drive roller 13 of the traveling carriage 10 and the like are rail portions 3a. , 3b are arranged so as to plunge between the carriages 3b and 3b, so that there are few portions of the traveling carriage 10 that project above the rail 1, and therefore, when compared with the conventional device configured so that the traveling carriage holds the rails, The railcar 1 can be installed at a position closer to the ceiling portion or the ground to drive the traveling carriage 10.

That is, according to the above-mentioned monorail type traveling device, the traveling carriage 10 is placed in a place closer to the ceiling portion, in a narrower place, than in the conventional monorail type traveling device of this type.
Alternatively, there is a feature that the traveling performance is enhanced in that the vehicle can travel along a turning path having a relatively small diameter.

Therefore, the degree of freedom in designing the running track is increased, and it becomes possible to provide an optimal running track according to the layout of the building or a running track that can fully utilize the work space. In particular, when the monorail type traveling device is used for monitoring as in the above embodiment, in order to effectively monitor each place in a limited space such as a turbine room, the traveling carriage can be used in a narrower space. Although it is required to drive the vehicle, the monorail type traveling device of the above embodiment can suitably meet such a requirement.

Further, in the monorail type transporting apparatus, as described above, since the motor 12 having a comparatively heavy weight is arranged below the rail 1, it becomes easy to maintain the weight balance of the traveling carriage 10 when traveling on a horizontal track. Therefore, it is possible to effectively suppress the occurrence of vibration and noise at the time of traveling due to the imbalance of weight, overload on the drive mechanism, unnecessary shake of the handling means, and the like.

Further, since the trolley wire 4 and the drive rollers 13 of the traveling carriage 10 are arranged on different sides with the rail-constituting wall 2 of the rail 1 interposed therebetween, the trolley wire 4 and the current collector 29 are arranged. The dust (for example, carbon powder) generated by the sliding contact of the
Therefore, there is also an advantage that it is possible to prevent the occurrence of slip due to the dust adhering to the drive roller or the like.

The monorail type traveling device of the above embodiment is one example of the monorail type traveling device of the present invention, and its specific structure can be appropriately changed without departing from the gist of the present invention. .

For example, although the chain 6 is omitted in the horizontal track portion in the above embodiment, the chain 6 may be provided over the entire range of the running track of the running track. A rack may be applied instead of the chain 6 as the meshing means.

Further, in the above-described embodiment, the monorail type traveling device is applied as the monitoring device by mounting the monitoring camera 30 on the traveling vehicle 10, but of course, it may be used for purposes other than the monitoring device. it can. For example, instead of the monitoring camera 30, a handling device for loading and unloading the luggage may be connected to the traveling vehicle 10 to carry various items of luggage.

Further, in the above-described embodiment, the rail 1 is formed in the I-shaped cross section having the rail-constituting wall 2 and the rail portions 3a and 3b horizontally projecting to both sides at the upper and lower ends thereof. Other than this, the rail 1 may have a U-shaped cross section in which the rail portion projects to one side at the upper and lower ends of the rail-constituting wall 2.

[0045]

As described above, according to the monorail type traveling apparatus of the present invention, since the drive wheels are projected between the upper and lower rail portions, the traveling carriage has a small portion protruding upward from the monorail track. The motor is arranged below the drive wheels and directly below the monorail track, and the mechanism for tilting and vertical traveling, that is, the meshing means and the rotary member meshing with the mechanism, are respectively arranged below the monorail track. As a result, there are few protruding parts in the width direction of the traveling carriage. Therefore, the mounting portion of the traveling carriage on the monorail track is made compact, and it is possible to travel in a narrower space and to travel on a relatively small diameter turning track (curve). Further, since the motor is arranged directly below the monorail track, the weight balance of the traveling carriage can be maintained well.

In such a monorail type traveling device, a transmission gear is attached to the first drive shaft on which the drive wheels are attached, and a passive gear which meshes with the transmission gear is attached to the second drive shaft on which the rotating member is attached. If the power transmission means is mounted so as to transmit the driving force of the motor to the first drive shaft via the belt transmission means, the driving force of the motor is surely transmitted to the drive wheel and the rotating member, and the precision is high. Can be driven.
