Abstract

PURPOSE:To smoothly move a moving beam by laterally moving a moving beam with each connecting pin to connect a plurality of moving beams held through a pin receiver on a truck, and making the connecting pin sliclable in the pin receiver in the longitudinal direction of the moving beam. CONSTITUTION:In the case where a branch start C is track-shifted between a reference position A. and a branch position B, lateral moving force is acted on each of trucks 4 by a hydraulic cylinder or the like. The lateral moving force is simultaneously transmitted to two adjacent moving beams in the connecting part of each of moving beams C1 to C4 through a pin receiver 11, a roller 9 and a connecting pin 1, and each of moving beams C1 to C4 is thereby laterally moved together with the truck 4. Since in this case, the pin receiver 11 moves in one body with the truck 4, and on the other hand the connecting pin 1 moves curvedly, moving force is transmitted as the pin receiver 11 and the connecting pin 1 move in the longitudinal direction of a track C. In addition frictional resistance occurring when the roller 9 moves to the pin receiver 11 decreases. Thus a moving force transmitting mechanism can be used in common between the adjacent beams, and the damage of a connecting part can be sharply reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branching device for switching the course of a magnetic levitation railway or the like.

[0002]

2. Description of the Related Art As a branching method of a magnetic levitation railway, a plurality of moving girders each having a U-shaped cross section are arranged in the lengthwise direction while being supported by a bogie device at each end in the lengthwise direction. , A branch track is formed by connecting the opposite ends by a connecting pin in the vertical direction so as to be rotatable relative to each other, and this branch track is a reference position at which the end moving girder on the branch end side is connected to the reference line, A traverser system is generally known in which the same moving girder is moved to and from a branch position connected to a branch line.

In the branching device adopting the traverser system, each trolley device is moved in the track width direction by a conversion drive device having a hydraulic cylinder, a hydraulic motor or the like as a drive source, and the motive force of the trolley device is moved by each moving girder. Is transmitted to each moving girder so that the moving girder can be moved together with the bogie device.

Conventionally, as a moving force transmitting mechanism for transmitting the moving force of the trolley device to the moving girder at the time of changing the track, the Japanese Patent Publication No.
As shown in Japanese Laid-Open Patent Publication No. 54201, slide metal is provided on the upper surface of the bogie device and slide plates are provided on the lower surface of the traverse device at the moving girder support portion (both end portions of each moving girder) by the bogie device, and slide is performed. There is known a structure in which a slide metal is engaged with a concave portion of a plate to transmit the moving force of the carriage device to the moving girder via the engaging portion.

[0005]

However, according to the known technique of transmitting and receiving the moving force to and from the bogie device on both sides of the end of the moving girder and for each moving girder in this way, The structure was complicated and the cost was high.

[0006] Further, the moving girder and the trolley device perform relative motion at the time of changing the track (during relative rotation between adjacent moving girders),
At this time, since only the slide plate performs the rotational movement around the connecting pin together with the movable girder while the slide metal is fixed, an unreasonable force acts on the engaging portions of both and the wear of these becomes severe.

Therefore, the present invention provides a railroad branching device which can simplify the structure of the moving force transmitting mechanism and which does not apply unreasonable force to the moving force transmitting portion.

[0008]

According to a first aspect of the present invention, a plurality of movable girders are arranged in the lengthwise direction and are adjacent to each other in a state in which the ends in the lengthwise direction are supported by a carriage device. Mutually connected to each other by a connecting pin in the vertical direction at the center portion in the width direction of the ends facing each other to form a branch orbit,
By moving the bogie device in the track width direction, the branch track is divided into a reference position where the end moving girder on the branch end side is connected to the reference line and a branch position where the moving girder is connected to the branch line. In a railway in which the traveling girders are switched between the moving girders by switching between the moving girders, the moving girders can be integrally moved in the widthwise central part of the bogie device at the connecting portions of the moving girders with respect to the connecting pin. A pin receiving member that engages in a relatively movable state in the length direction is provided, and the connecting pin and the pin receiving member constitute a moving force transmission mechanism that transmits the moving force of the bogie device to the moving girder.

According to a second aspect of the present invention, in the structure of the first aspect, a roller is rotatably provided around the pin at an engaging portion of the connecting pin with the pin receiving member.

[0010]

According to the above construction, the moving force of the carriage apparatus is simultaneously transmitted to the two adjacent moving girders via the pin receiving member and the connecting pin. In other words, since one moving force transmission mechanism is shared by two moving girders, the structure of the moving girder is far superior to the conventional moving force transmission mechanism that separately transmits moving force for each moving girder. It will be easy.

Further, since relative movement does not occur between the connecting pin and the pin receiving member at the time of relative rotation between adjacent moving girders, an unreasonable force is not generated on them.

On the other hand, according to the second aspect of the invention, since the relative movement of the connecting pin and the pin receiving member during the movement of the carriage device is performed by the rolling movement, the frictional resistance between them is small.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an outline of the entire branching device according to this embodiment will be described with reference to FIGS.

A1 is a fixed girder on the branch start point side of the reference line (main line track), A2 is a fixed girder on the end point side, and B is a branch line (lateral line track)
The fixed girder on the base end side of C is a branch orbit, and this branch orbit C is
On the floor surface F (see FIG. 2), the vertical pin P at the end of the branch start point is used as a fixed fulcrum, and the end of the branch end is connected to the fixed girder A2 of the branch end of the reference line as shown in FIG. By moving between the reference position and the branch position where the end point on the branch end point side is connected to the fixed girder B on the base end side of the branch line as shown in FIG. 6, the train route is divided into the reference line and the branch line. Can be switched between.

In this branch orbit C, a plurality of moving girders C1 to C4 (four in the figure, which will be described below in this example) having a U-shaped cross section arranged in the longitudinal direction face each other. The end portions are connected to each other by connecting pins 1 in the vertical direction so as to be rotatable relative to the pins. 2 and 3 are brackets for this connection.

Each moving girder C1-C4 has a length direction (hereinafter,
(This direction is called the front-back direction, and the moving girder width direction is called the left-right direction.)
Both sides of the end portion of are supported by the carriage device 4.

In this case, in the connecting portion of the movable girders, the opposite end portions are supported by the common bogie device 4, and the free end portion of the fourth movable girder C4 is supported by the single bogie device 4.

This trolley device 4 comprises a pair of left and right trolleys 5, 5.
Are movably connected by a connecting plate 6, and both carriages 5 and 5 are driven in the left-right direction on a rail 7 by being driven by a known conversion drive device using a hydraulic cylinder or hydraulic motor (not shown) as a drive source. To do.

Denoted at 8 are wheels of both carriages 5 and 5, and as shown in FIGS. 1 and 2, these wheels 8 are provided with collars 8a, 8a on both sides thereof, which are generated during movement of the carriage device 4. Forces in the front-rear direction that act on the trolley device 4 due to the relative movement of the trolley device 4 and the movable girder are received by the collars 8a, 8a and the rail 7.

Next, a moving force transmission mechanism for transmitting the moving force of the trolley device 4 to the moving beams C1 to C4 at the connecting portions of the moving beams will be described.

This moving force transmitting mechanism is common to each moving girder connecting portion, and representatively, FIGS. 1 to 3 show the moving force transmitting mechanism at the connecting portion of the second moving girder C2 and the third moving girder C3. ing.

The connecting pin 1 is formed longer than the length required for connecting the movable girders, and the lower end of the connecting pin 1 projects toward the trolley device 2 side. 3a is inserted.

A roller 9 is rotatably attached to the lower end portion of the connecting pin 1 through a bush 10 so as to be rotatable around the pin 1, and the roller 9 is attached to the center portion of the connecting plate 6 of the carriage device 4. It is engaged with the receiving member 11.

The pin receiving member 11 is a connecting plate 6
A pair of receiving plates 12 and 12 which are vertically provided on the upper surface of the pair with a space left and right, and slide plates 13 and 13 mounted inside the receiving plates 12 and 12, and the roller 9 is The slide plates 13 and 13 are sandwiched between the plates 13 and 13 in such a manner that they can move integrally in the left-right direction with respect to the slide plates 13 and 13 in the front-rear direction. .

The slide plates 13, 13
Has been heat-treated and surface-treated to improve wear resistance. Further, in FIG. 3, reference numeral 14 is a roller receiving plate attached to the connecting plate 6 in a state of being in contact with the lower surface of the roller 9 in order to smooth the movement of the roller 9.

On the other hand, each moving digit C1 to
As a supporting mechanism for smoothly performing the relative motion between C4 and the bogie device 4 with a small frictional resistance, as shown in FIGS. Of the sliding girder 15 made of a material having a small frictional resistance, and a sliding plate 16 made of metal or plastic which is in contact with the sliding girder 15 is provided on the lower surface of the moving girders C1 to C4.

In this configuration, the reference position of FIG. 5 and FIG.
At the time of changing the track to and from the branch position, the lateral moving force applied to each bogie device 4 by the conversion driving device (not shown) is applied to the pin receiving member 1 at each moving girder connecting portion.
It is simultaneously transmitted to two adjacent moving girders via the roller 1, the roller 9 and the connecting pin 1, whereby the respective moving girders C1 to C4 move in the left-right direction together with the carriage device 4.

In this case, the pin receiving member 11 is the carriage device 4
While the connecting pin 1 moves in a curved line, the connecting pin 1 moves in a curved manner, and the moving force is transmitted while the connecting pin 1 relatively moves in the front-rear direction. Further, at this time, the rolling movement of the roller 9 causes the connecting pin 1 to move relative to the pin receiving member 11, so that the frictional resistance therebetween can be minimized.

When the orbit is changed, two adjacent moving girders make a relative rotational movement, but at this time, no relative movement occurs between the connecting pin 1 and the pin receiving member 11. Therefore, there is no possibility that an unreasonable force acts on the engaging portion between the two.

Since the free end portion of the fourth movable girder C4 does not have the connecting pin 1, the vertical pin 17 is provided at the center of the free end portion in the left-right direction in place of the connecting pin 1. The vertical pin 17 engages with the pin receiving member 11 provided at the center of the bogie device 4 to form a moving force transmission mechanism.

By the way, although the roller 9 is provided on the connecting pin 1 in the above embodiment, the connecting pin 1 is directly connected to the pin receiving member 11.
May be engaged with each other and the both may be moved relative to each other by a sliding motion.

[0032]

As described above, according to the present invention, the moving force transmitting mechanism at the connecting portion of the moving girders is constituted by the connecting pin and the pin receiving member provided in the carriage device,
Since one moving force transmission mechanism is shared by two adjacent moving girders, the structure of the moving girder is much simpler than the conventional moving force transmission mechanism that transmits moving force separately for each moving girder. Becomes

Further, since relative movement does not occur between the connecting pin and the pin down member at the time of relative rotation between the adjacent moving girders, an unreasonable force is not generated on them. Therefore, the moving force transmitting mechanism is less worn and the life is improved.

On the other hand, according to the invention of claim 2 in which the roller is attached to the connecting pin, the relative movement of the connecting pin and the pin receiving member during the movement of the carriage device is performed by the rolling movement, so that the frictional resistance between them is small and the movement is reduced. The force transmission is carried out smoothly and their wear is further reduced.
