Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field relating to a mechanism that enables passage of a branch rail point of an apto type traveling vehicle.

[0002]

2. Description of the Related Art In general, an APT type traveling vehicle is provided with traveling wheels that roll on a traveling rail and pinion wheels that mesh with a rack rail. The rack rail is laid between the traveling rails. Therefore, if the apto type traveling vehicle travels in the same traveling mode, the pinion wheels will collide with the traveling rail at the branch rail point.

Conventionally, it has been known to use a traverser as means for allowing passage of a branch rail point of an apto type traveling vehicle. This conventional first means is
With the traverser installed near the branch rail point, the entire apt-type traveling vehicle is lifted and laterally moved to move above the branch rail point, thereby causing the apt-type traveling vehicle to pass.

Further, as another conventional means, it is known to cut off a part of the traveling rail at the branch rail point. The second conventional means is to cut the traveling rail to form a passage gap for the pinion wheels on the traveling rail.

[0005]

The above-mentioned first means of the prior art requires the installation and operation space of the traverser, so that it cannot be used inside a tunnel, which is a limited space. There is. Further, the above-mentioned second means of the related art has a problem that the traveling wheels may be derailed from the excised portion of the traveling rail.

The present invention has been made in consideration of the above problems, and an object thereof is to provide an apto-type traveling vehicle having a mechanism capable of safely passing a branch rail point in the vehicle itself. To do.

[0007]

In order to solve the above-mentioned problems, the apto type traveling vehicle according to the present invention adopts the following means.

That is, according to the first aspect of the present invention, in an apto type traveling vehicle having traveling wheels rolling on the traveling rail and pinion wheels meshing on the rack rail, the traveling wheels and the pinion wheels are supported non-coaxially. The vehicle is characterized in that the axle of the traveling wheels is supported by the vehicle body so as to be capable of ascending and descending, and a lifting mechanism is provided between the axle of the traveling wheels and the vehicle body.

With this means, when the lifting mechanism is operated,
The vehicle body rises and the pinion wheels are pulled up to a position higher than the traveling rail, but the traveling wheels are left on the traveling rail. Therefore, at the branch rail point, the pinion wheels can pass without colliding with the traveling rail.

According to a second aspect of the invention, in the apto type traveling vehicle according to the first aspect, the driving force of the traveling drive source is transmitted from the pinion wheel side to the traveling wheel side through a chain type drive transmission member whose tension is adjusted by a tensioner. It is characterized by being transmitted to.

According to this means, the traveling wheels that move up and down with respect to the vehicle body are located below the traveling drive system, and the change in the axial distance between the pinion wheels and the traveling wheels due to the operation of the elevating mechanism is absorbed by the tension of the drive transmission member. As a result, the traveling drive system is smoothly transmitted.

[0012] According to a third aspect of the invention, the apto-type traveling vehicle according to the second aspect further includes a sensor for detecting disconnection of the drive transmission member.

By this means, the disconnection of the drive transmission member due to the frequent fluctuation of the tension of the drive transmission member due to the operation of the lifting mechanism is immediately detected.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of an apto type traveling vehicle according to the present invention will be described below with reference to the drawings.

In this embodiment, a battery electric drive type used in a gallery is shown.

A traveling rail 1, on which this embodiment travels
The rack rail 2 is laid on a common sleeper 3 made of H-shaped steel and installed on the bottom of the gallery. Running rail 1
Consists of two common rails. Rack rail 2
Is laid between the traveling rails 1, and in order to prevent the accumulation of soil and sand and the retention of water and oil, the pins 2b are arranged in parallel between the opposing grooved steels 2a with a certain interval. Things have been adopted.

In this embodiment, the vehicle body 5 is formed in a box shape. A driver's seat 6 is provided on the front side of the vehicle body 5. A battery 7 is mounted in the center of the vehicle body 5. Then, inside the vehicle body 5, two pairs of motors 8 and speed reducers 9 which are electrically connected to the battery 7 and which are traveling drive sources are suspended and supported by the side wall of the vehicle body 5 (points A and B) and are laterally reversed. It is housed side by side in parallel.

Two pairs of traveling wheels 10 on the front side and the rear side, which have a relatively slightly smaller diameter, are rollingly traveling on the traveling rail 1.
The two pinion wheels 11 having a relatively slightly larger diameter that mesh with the rack rails are supported non-coaxially.

Axle 12 on which traveling wheels 10 are supported
Are supported by the vehicle body 5 so as to be able to move up and down. Then, between the upper portion of the axle housing 12a of the axle 12 and the roof wall of the vehicle body 5, a lifting mechanism 13 including a hydraulic cylinder is provided.
Is equipped.

Axle 1 on which pinion wheels 11 are supported
4 is fixedly supported by the speed reducer 9. The axle housing 14 a of the axle 14 is fixed to the housing of the speed reducer 9. The axle shaft 14 b of the axle 14 is connected to the power takeout part of the speed reducer 9.

A sprocket gear 15 having a relatively small diameter is coaxially fixed to the axle shaft 12b of the axle 12 of the traveling wheel 10. A sprocket gear 16 having a relatively slightly larger diameter is coaxially fixed to the axle shaft 14b of the axle 14 of the pinion wheel 11. And these sprocket gears 15,
Between 16 is a drive transmission member 1 consisting of a chain belt.
7 has been passed over. Further, the drive transmission member 17 includes
A tensioner 18 for applying tension is attached. Further, a sensor 19 for detecting disconnection of the drive transmission member 17 is installed near the drive transmission member 17.

Further, in this embodiment, the floating prevention guide wheel 20 that runs on the grooved steel 2a of the rack rail 2 is supported by the vehicle body 5.

Further, in this embodiment, the lower end point La of the pinion wheel 11 at the normal time is located below the upper end point Lb of the traveling rail 1, as shown in FIG.

In the embodiment configured as described above, the driving force of the motor 8 as a traveling drive source is transmitted to the pinion wheels 11 via the speed reducer 9 using the battery 7 as a drive energy source, and at the same time, the drive transmission is performed. It is also transmitted to the traveling wheel 10 via the member 17 and the like. Therefore, when the motor 8 is driven, the traveling wheels 10 roll on the traveling rail 1, the pinion wheels 11 mesh with the rack rail 2, and the vehicle body 5 moves forward or backward.

As described above, the two drive systems can be dedicated to forward or reverse, or both can be used for forward and reverse by switching the forward and reverse rotations.

When the vehicle reaches the branch rail point during traveling, the elevating mechanism 13 is operated.

When hydraulic pressure is input to the lifting mechanism 13, the vehicle body 5
Is pushed up and raised, and the traveling wheels 10 are pushed down by the reaction force and left on the traveling rail 1. The raised vehicle body 5 also integrally raises the pinion wheels 11 which are fixedly supported. As shown in FIG. 3, the ascending width of the pinion wheel 11 is set so that the lower end point La ′ of the pinion wheel 11 is located above the upper end point Lb of the traveling rail 1. In addition, since the rising width of the pinion wheel 11 is extremely small, there is no problem such as contact with other parts even inside the gallery. Further, since the rack rail 2 is removed at the branch rail point, the floating prevention guide wheel 20 is not caught by the grooved steel 2a of the rack rail 2 and the rise of the vehicle body 5 is not prevented.

When the vehicle body 5 is raised, the traveling wheels 1
0, the inter-axle distance of the pinion wheels 11 is extended, but the extension of the inter-axle distance is absorbed by the fluctuation of the tension of the drive transmission member 17 formed of the chain belt provided with the tensioner 18, and the transmission of the drive transmission system is prevented. Will hold.

Therefore, if the motor 8 is driven as it is, the vehicle body 5 moves forward or backward only by rolling the traveling wheels 10 on the traveling rail 1. As a result, the pinion wheels 11 can pass through the branch rail point without colliding with the traveling rail 1. Since the traveling rail 1 does not have a removed portion as in the conventional example, there is no fear of derailment and the vehicle can pass safely.

After passing through the branch rail point, when the hydraulic pressure of the lifting mechanism 13 is discharged, the vehicle body 5 descends and returns to the normal traveling state.

When the drive transmission member 17 is fatigue-cut due to the frequent change in the tension of the drive transmission member 17 due to the repeated lifting and lowering of the vehicle body 5, the sensor 19 detects this. Therefore, since the repair can be immediately performed by the detection signal of the sensor 19, the vehicle body 5 is not lifted at the branch rail point and the pinion wheels 11 are idled without knowing the disconnection to prevent the vehicle from running.

As described above, in addition to the illustrated embodiment, the drive system of the motor 8 or the like can be constituted by an internal combustion engine or the like.

Further, the lifting mechanism 13 can be composed of other equipment such as an air cylinder.

[0034]

As described above, the apto type traveling vehicle according to the present invention is provided with the elevating mechanism for elevating and lowering the vehicle body and the pinion wheels, and the collision between the pinion wheels and the traveling rail can be avoided with a slight elevation. There is an effect that it can be used for passage of a branch rail point even in a tunnel where the space is limited.

Further, since the traveling rail does not require a removed portion, there is an effect that there is no danger of derailment and the vehicle can safely pass through the branch rail point.
