Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a front and rear two-wheel drive system that rolls on a pair of left and right guide rails.
This invention relates to a steering device for a transport train equipped with supporting wheels.

(Prior Art) A conventional steering device for this type of transport train is provided with a pair of front and rear bogies, each pivoted by a vertical support shaft at the center position in the width direction of the train. A support wheel that rolls on a guide rail and a guide roller that follows the guide rail, or a support wheel that engages with the guide rail so that it can follow the guide rail, were pivotally supported at both left and right ends, respectively.

(Intelligence B to be solved by the invention) In the conventional steering device as described above, the main body of the train is supported only at the bogie bogie rocking centers at two locations, front and rear, so the vertical support to which the bogie is pivoted is required. Unless the diameter of the shaft is increased to sufficiently increase the support strength, it will not only be impossible to support the train body stably, but also if the radius of curvature of the horizontal curve of the running route is small, each bogie will Since the amount of inward rocking of the bogie becomes very large, it becomes difficult to effectively use the space between the bogies as an installation space for linear motors and the like.

In order to solve the above-mentioned conventional problems, the present invention has the following features:
In a transport train equipped with two sets of front and rear support wheels that roll on a pair of left and right guide rails, each support wheel is separately attached to a wheel shaft supporting member that can swing around a vertical support shaft. The pair of left and right wheel shaft support members are interlocked and connected to each other so that they steer in the same direction for each set of front and rear wheels, and the guide rails are connected only to the wheel shaft support member located on one side from the left and right sides The present invention proposes a steering device for a transport train, in which a sandwiching positioning guide roller is pivotally supported, or the supporting wheel is engaged with a guide rail so as to be able to follow the same.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In Figures 1 to 4, 1 is a transport train, and a pair of left and right guide rails 2A are laid along the running route.
, two pairs of left and right supporting wheels 3a, 3b and 4a, 4b rolling on 2B, and one guide rail 2.
The supporting wheels 3a and 4a that roll the AJ2 are supported by vertical shafts on the wheel shaft supporting members 5a and 6a, respectively, so as to sandwich the guide rail 2A from the left and right sides at two places, front and back. It includes a positioning guide roller 7.8 and a pair of left and right linear motor bodies 9A and 9B.

The wheel shaft supporting members 5a, 6a and the wheel shaft supporting members 5b, 6b, which respectively pivotally support the supporting wheels 3b, 4b rolling on the other guide rail 2B, are located at the bottom of each of the boilers 33 to 4b, respectively. Vertical support shaft 10a~+t in upper position
b, and each pair of left and right wheel shaft support members 5a.

5b, 6a, and 6b are interlocking arms 12a, 12b, and 13a, 13b connected from these wheel shaft supporting members.
and are interlocked via interlocking links 14 and 15 so as to move in the same direction.

The linear motor bodies 9A, 9B have brackets 16a, 17a, 16b, 17b protruding from both front and rear ends thereof, and brackets 16a, 17a, 16b, 17b are provided from the front and rear wheel shaft support members 5a, 6a, 5b, 6b located on the same left and right sides. At the inner ends of the support arms laa, 19a and T13b, 19b, which are connected to each other,
The brackets 16a, +7a and 16b, 17b
Both front and rear ends of each linear motor main body 9A, 9B are swingably supported by vertical support shafts 20a, 21a and 20b, 21b.

The brackets 17a and 17b are provided with elongated holes 22a and 22b that extend in the longitudinal direction of the linear motor bodies 9A and 9B, and the vertical support shafts 21a and 21b pass through these elongated holes. Also, the brackets 16 on both ends of the linear motor main body
a, 17a and 16b, 17b, when the gap between these linear motor bodies 9A, 9B and the guide rails 2A, 2B becomes below a certain value, two guide rails, two
1 for protecting the left and right linear motors that come into contact with B
Colas 23 and 24 are pivotally supported.

25 is a power supply rail unit, and both guide rails 2
The wheel shaft supporting member 5a of the transport train 1 is supported by one side of the support rail 26 laid between A and 2B.
, 6a is in sliding contact with each other, power is supplied to the linear motor bodies 9A, 9B, etc., and control signals are exchanged between the main controller on the ground side and the sub-controller on the transport train 1 side. It will be done. A cover plate 28 having a gate-shaped cross section is attached to the support rail 26 to cover the pair of left and right guide rails 2A, 2B and the power supply rail unit 25, and each supporting wheel 33 to 4b etc. are configured to pass inside this cover plate 28. Therefore, as shown in FIG.
3 to 6b extend outward and upward through the lower sides of both sides of the cover plate 28, and are pivotally connected to the conveyance train 1 at the outer upper side of the cover plate 28 by vertical support shafts 10a to 10llb.

Both guide rails 2A and 2B are provided with supporting wheels 3a to 2B so as to serve as secondary conductor rails for linear motors.
The wheel 4b has a laminated structure portion consisting of a non-magnetic plate made of aluminum or the like forming a wheel rolling surface on which the wheel rolls, and an iron plate laminated inside the non-magnetic plate.

In the linear motor-driven transport device configured as described above, the wheel rolling running surface (secondary conductor surface for linear motor) in the pair of left and right guide rails 2A, 2B is
By energizing and energizing the pair of left and right linear motor bodies 9A, 9B facing each other with a small gap in between, these linear motor bodies 9A, 9B and the guide rail 2A,
As is well known, a thrust force is generated in a predetermined direction on the transport train 1 by the magnetic action between the secondary conductor part (the laminated structure part of the non-magnetic plate and the iron plate) of the transport train 1. It can be made to run on its own along both guide rails 2A and 2B.

However, as shown in FIG. 4, when the transport train 1 travels along a horizontally curved route, the supporting wheels 3a, 4a rolling on the guide rail 2A on one side are aligned with the wheel axes by the positioning guide rollers 7.8. The support members 5a and 6a follow the bending of the guide rail 2A and the vertical support shafts 10a and ll.
Since it swings around a, it is automatically steered in the bending direction of the guide rail 2A. Then, the steering motion of the wheel shaft support members 5a, 6a is transmitted to the wheel shaft support members 5b, 6b on the opposite side via the interlocking arms 12a to 13b and the interlocking links 14.15.
Since b also swings in the same direction around the vertical support shafts 10b and llb, the supporting wheels 3b and 4b that are pivotally supported on the wheel shaft support members 5b and 6b also automatically move in the direction of bending of the guide rail 2B. be steered. Therefore, the transport train 1 can run smoothly on the horizontal curve route. In this case, as shown in FIG.
By shortening the effective length of 5 and making the interlocking arms 12a, 12b and 13a, 13b not parallel to each other but inclined in a V-shape, the support is forcefully steered by the positioning guide rollers 7.8. wheel 3a
.

When the radius of the two guide rails supporting the guide rail 4a is smaller than that of the other guide rail 2B (inside the horizontal curve path), the wheels 3a and 4a rolling on the two guide rails 2B are If the steering angle θb of the wheels 3b and 4b rolling on the other guide rail 2B is smaller than the steering angle θa, and vice versa (the guide rail 2
When A is outside the horizontal curve path section), the steering angle θ of the wheels 3a and 4a rolling on the two guide rails is
The steering angle θb of the wheels 3b and 4b rolling on the other guide rail 2B is larger than that of a. Therefore, when traveling on a horizontal curve route, which wheels 3a to 4
b also has its rotation center axis Ca, Cb is the guide rail 2A,
Each wheel 3 is moved in the direction passing through the center of the circular arc of 2B, in other words, in the tangential direction of the guide rails 2A and 2B at each wheel position.
The interlocking arms 12a to 13b are oriented so that a to 4b are oriented.
By setting the length of link 14 and 15,
Each of the wheels 3a to 4b can be rolled and run on the guide rails 2A and 2B in the horizontal curved path portion with the least resistance.

On the other hand, when the transport train 1 travels along the horizontal curve route section as described above, as shown in FIG.
, 2B, the movement of the wheel shaft support members 5a, 6a, 5b, 6b that automatically performs steering motion in the bending direction of the linear motor bodies 9A, 9B is transmitted via the support arms 18a to 19b and the vertical support shafts 203 to 21b. , and both linear motor bodies 9A and 9B are automatically moved laterally to the outside of the guide rails 2A and 2B (in the direction away from the center of the arc) curved in an arc shape, and the guide rail 2A.

This prevents each linear motor body 9A, 9B from coming off the surface of the motor 2B, that is, directly above the wheel rolling surface that also serves as a secondary conductor surface.

The means for interlocking and connecting the pair of left and right wheel shaft support members is not limited to that of the above embodiment; for example, as shown in FIG. 5, a pair of left and right wheel shaft support members 5a, 5b and 6a,
Interlocking arms 30a, 30 are connected outwardly from 6b, respectively.
Tension chains (or wires, etc.) 32, 33 are stretched between 31a and 31b, and each wheel shaft supporting member 5a.

Tension springs 36 and 37 for constantly tensioning the tension chains 732 and 33 are tensioned between interlocking arms 34a and 34b and between 35a and 35b, which are connected inwardly from 5b and 6a and 6b, respectively. A pair of wheel shaft support members 5
a, 5b and 6a, 6b can also be interlocked and connected to each other so as to steer in the same direction.

Of course, in this case as well, each tension check 732.33 is
Idle gear ring 5B fixed in position so as to bend into a dogleg shape.
, 39 in the intermediate position, all wheels 33 to 4b are guided in the direction in which their rotation center axes Ca and Cb pass through the arc centers of the guide rails 2A and 2B when traveling on the horizontal curve path as described above. to direct,
Steering angle θa of wheels 3a, 4a and wheels 3h, 4
The steering angle θb of b can be changed.

Although a linear motor is used as a propulsion means for the transportation train 1, it can also be configured to be propelled using a general rotary motor that drives at least two of the supporting wheels 3a to 4b. . In addition, although the positioning guide roller 7.8 was also used, the support wheel 3a,
4a may be a grooved wheel that fits into the guide rail 2/1m, or the wheel 3a may be installed in a groove provided in the guide rail 2A.
.

4a, etc., to support the wheel 3a.

If 4a is configured for a follow-up steering movement along two guide rails, the positioning guide rollers 7.8 can be omitted.

(Operations and effects of the invention) As described above, according to the steering device for a transport train of the present invention,
The four parts of the train can be supported separately by the four wheel shaft support members that each support the support wheels, so even if the train is used for transporting heavy loads, the vertical support shafts for steering can be Since this burden is reduced, the structure of the part becomes easy, and the train body can be stably supported. Moreover, in the horizontal curve route section, the distance between the inner and outer guide rails in the direction connecting the left and right pair of support wheels increases, but without being affected by this, each support wheel can be attached to the horizontal curve route section. Since the steering movement can be made along both the inner and outer guide rails, the transport train can run smoothly on the horizontal curve route.

Also, compared to the case where a pair of front and rear bogies are used, the amount of oscillation of each wheel shaft support member is smaller, so as in the example, the space between the front and rear wheel shaft support members is used as the installation space for the linear motor body, etc. It can be used effectively.
