Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a monorail branching device that allows a lifting machine such as a hoist to change direction during movement, and particularly relates to a monorail branching device suitable for installation in a narrow space. .

[Background of the invention]

BACKGROUND ART Conventionally, there is a monorail device in which a rail member having an I-shape in cross section is installed on the ceiling of a building for transporting equipment, etc., and the rollers of a lifting device such as a hoist are supported on the lower side of the rail member so as to be movable.

Conventionally, the lifting machine direction changing means of this monorail system has mainly used a rail member curved into a U-shape in plane. However, since the rail member is curved, there is a drawback that a relatively large rail installation space is required. In addition, when changing the direction of a lifting machine in a place with little space, the lifting machine must be removed from one monorail and moved to the other monorail, which requires a lot of time and effort.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a monorail branching device that allows a lifting machine to easily and quickly change direction between multiple rails even in a narrow space.

[Summary of the invention]

The monorail branching device according to the present invention includes a fixed monorail in which a plurality of rail members are arranged on the same plane in an intersecting manner, and a fixed monorail arranged at the intersection of each of the fixed monorails, and a fixed mole -λ with a vertical turning axis. A rotating monorail that can change the direction of the rail is provided in between, and the lifting machine can perform the necessary change of direction while stopped on the rotating monorail, and easily move from one fixed rail to the other. I'm trying to make it possible.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Figure 1 shows an example of the schematic layout of a monorail.
A plurality of fixed monorails 2 are arranged vertically and horizontally, and swing monorails 4 are arranged at the intersections of the fixed monorails 2 so as to be able to turn via pivot shafts 6, respectively. Predetermined rotating monorails 4 are connected by interlocking members 8 so that they can rotate simultaneously.

2 to 8 show the rail configuration in detail. The fixed monorail 2 consists of a rail member with an approximately ■-shaped cross section (6th
figure). An example of the lower side 2a of this rail member is used as a roller guide for a lifting machine such as a hoist, and the upper side 2b is fixed to the building ceiling 12 by a hanging device 9 (FIG. 2). The swing guide rail 4 has the same cross-sectional shape as the fixed monorail 2 (approximately I
It consists of a rail member of the shape). The lower side 4a of this rail member
One example part is used as a roller guide of a lifting machine, and the central part of the upper side 4b in the longitudinal direction and the width direction is connected to the building ceiling 12 by the pivot shaft 6.
(Figure 2).

As shown in FIG. 2, the pivot shaft 6 includes a support shaft 18 suspended from a mounting member 14 such as a ceiling-embedded metal fitting or a steel beam via a holder 16, and a cylindrical shaft rotatably fitted onto the support shaft 16. and a housing 20. The upper side 4b of the swing monorail 4 is fixed to the lower end of the housing 20 with bolts 21. The support shaft 18 is the holder 16
The screw portion 22 at the top is screwed into the fixing nut portion 16a of the support shaft 18.
Furthermore, the height level of the rotating monorail 4 can be adjusted.

Level adjustment is performed via an L-shaped level adjustment lever 24 inserted into the support shaft 18, and installation is sometimes performed by rotating the support shaft 18. When the heights of the rotating monorail 4 and the fixed monorail 2 match, the tip 24a of the level adjustment lever 24 is
is fixed to the holder 16 by welding or the like.

As shown in FIG. 2, the housing 20 is fitted onto the support shaft 18 via a radial hair ring 26 and a thrust bearing 28. The eightaging 20 is connected to an operating cable 32 via a gear mechanism 30 such as a bevel gear, and is driven to rotate manually, electrically, hydraulically, or the like. Both end portions 4C of the swinging monorail 4 and the end portions 2C of each fixed monorail 2 adjacent thereto are mutually formed into an arc shape, allowing the swinging monorail 4 to turn smoothly.
When the turning monorail 4 is stopped, the ends thereof are arranged close to each other. At each end, there is a rail stopper mechanism 34 for stopping the swinging monorail 4 in series with the fixed monorail 2, and a rail stopper mechanism 34 that operates in conjunction with this to stop the rollers 36 of the lifting machine on the rail during the swing. A roller stopper mechanism 38, 39 is provided which opens after turning.

As shown in FIGS. 2 and 4, the rail stopper mechanism 34 includes an engagement arm 40 that projects from the upper side 4b of the rotating monorail 4 and extends to a position covering the upper side 2b of the fixed monorail 2, and this locking arm 40. It is composed of a rotary wheel 44 which is pressed and held downward by a spring 42, and a corrugated guide member 4 that protrudes from the upper side 2b of the fixed monorail 2 and receives the rotary wheel 44. The corrugated guide member 48 has four parts 48a in which the rotating ring 44 pressed by the spring 42 collapses when the swinging monorail 4 swings to a position where it is in series with the fixed monorail 2. At this position, the swinging monorail 4
It is designed to stop and hold. The operator detects in advance the resistance force when the rotating wheel 44 passes through the convex portions 48b in front of the four parts of the waveform guide member 48, and the rotation drive motor (
In consideration of the output of
Adjustment is made so that a smooth locking force for the monorail 4 can be obtained by operating the .

Furthermore, roller stopper mechanisms 38 and 39 are attached to each of the vertical sides 2d and 4d of the fixed monorail 2 and the rotating monorail 4, respectively. The roller stopper mechanism 38 on the fixed monorail 2 side, as shown in FIG. A stopper actuating lever 56 that is provided so as to be integrally movable with the stopper 54 via a shaft 52 and protrudes upward as an example of the fixed monorail 2, and a spring seat 58.
The plate spring 60 is attached to the fixed monorail 2 via a plate spring 60 and presses the stopper 54 to one side of the fixed monorail 2. In the roller stopper mechanism 38 of the fixed monorail 2 which is in a disconnected state from the rotating monorail 4, the stopper 5
4 is pressed by the leaf spring 60 and protrudes to one side of the vertical side 2d, and becomes in a state of preventing the transfer of the roller 36 of the lifting machine (
(state indicated by the solid line in Figure 6). Also, the roller stopper mechanism 38 of the fixed monorail 2 that is connected to the rotating monorail 4
In this case, the engagement arm 40 protruding from the upper side 4b of the rotating monorail 4 pushes the stopper operating lever 56 to one side (in the direction of arrow A), so that the stopper 54 is moved against the elastic force of the leaf spring 60. It retreats to the vertical side 2d side of the fixed monorail 2, and becomes in a state where the rolling of the roller 36 of the lifting machine is allowed (
(state of virtual line in Fig. 6).

On the other hand, as shown in FIG.
A stopper 64 is rotatably suspended from one part via a horizontal support shaft 62, and a stopper actuator is provided to be able to operate integrally with the stopper 64 via the support shaft 62 and rises to the vicinity of the bottom of the side 4b of the rotating monorail 4. It consists of a lever 66 and a leaf spring 68 that presses the switch/socket 64 to one side of the rotating monorail 4. Rotating monorail 4 is fixed monorail 2
When the vehicle is not lined up in series, that is, when it is in the middle of a turn,
The stopper 64 is pressed by the leaf spring 68 and protrudes to one side of the vertical side 4d, and becomes in a state of preventing the transfer of the roller 36 of the lifting machine (the state shown by the solid line in FIG. 7). Furthermore, when the swinging monorail 4 swings in one direction (direction of arrow B) and becomes connected to, for example, the fixed monorail 2 (2A) placed toward the right in FIG. 3, the fixed monorail 2 (2A) A retaining pin 70 protruding from the vertical side 2d comes into contact with the stopper operating lever 66 through a through hole 72 formed on the vertical side 4d of the swinging monorail 4, whereby the stopper 64 is moved by the leaf spring 68.
resisting the elastic force of the swinging monorail 4 and retreats to the vertical side 4d side of the swinging monorail 4, resulting in a state in which transfer of the rollers 36 of the lifting machine is permitted (the state indicated by the imaginary line in FIG. 7). Conversely, when the swinging monorail 4 swings in the other direction (direction of arrow C in FIG. 7) and becomes connected to, for example, the fixed monorail 2 (2B) arranged upward in FIG. The presser arm 74 protruding from the vertical side 2d of 2 (2B) directly contacts the stopper 64, which causes the stopper 64 to retract toward the vertical side 4d of the rotating monorail 4 against the elastic force of the handling spring 68. However, as in the case of turning in one direction, the lifting machine enters a state in which the rollers 36 of the lifting machine are allowed to shift (the state indicated by the imaginary line in FIG. 7).

Further, the interlocking mechanism between the rotating monorails 4 is composed of a link mechanism. That is, as shown in FIGS. 3 and 8, brackets 78 are protruded from both ends of the upper sides 4b of the rotating monorails 4 that are to be interlocked with each other, and the brackets 78 are connected by link arms 80, respectively. The end of the link arm 80 extends beyond the bracket 78,
The extending end portion thereof is connected to a rotation link 82 provided on the upper side 2b of the fixed monorail 2. As a result, the rotating monorail 4 to be interlocked rotates by the same angle as the rotating link 82.

Each link arm 80 is provided with an adjustment spring 83 for positioning the interlocking swing monorail 4 when initially installed.

After setting the initial position, the spring 83 is locked in a non-extendable state, creating a rigid structure in which the section of the link arm 80 is constant.

Note that a trolley bus 84 is provided in parallel to the fixed monorail 2 and the rotating monorail 4, respectively.

This trolley bus 84 is connected and disconnected in the same direction as the rotating monorail 4. A center feed box 86 is provided on the trolley bus 84 attached to the rotating monorail 4.

FIG. 9 shows an example of the use of the monorail branching device configured as described above. That is, three parallel fixed monorails 2
A swinging monorail 4 is provided at each intersection branch of AI--2A3 and fixed monorails 2B1 and 2B2 that intersect with these, via an interlocking mechanism 8, so that they are in the same swing state.

As shown in FIG. 3A, it is assumed that the lifting machine first moves in the direction of the arrow along the fixed monorail 2A1 arranged at the upper part of the figure.

If the swinging monorail 4 is aligned with the direction of the fixed monorail 2A1, each roller stopper mechanism 38, 39 of the fixed monorail 2A1 and the swinging monorail 4 will be in a state that allows the lifting machine to run on its rollers. Therefore, the lifting machine is suspended on the rotating monorail 4 and rotated, for example, 90 degrees counterclockwise to bring it into the state shown in FIG. 4(B). During the turning, the lifting machine is kept from falling from the turning monorail 4 by the roller stopper mechanism 39. After turning, the roller stopper mechanisms 38 and 39 are again in the roller release state, so the lifting machine is moved in the vertical direction across the fixed monorails 2B1 and 2B2, as shown in FIG. 2C.

After that, when the lifting machine is placed on the swinging monorail 4 at a predetermined position, the swinging monorail 4 is turned in the opposite direction from the beginning, as shown in FIG.
The lifting machine is caused to run in the opposite direction to the first fixed monorail 2A3. In addition, the fixed monorail 2B in the middle part
The same applies to the case of shifting to 2.

According to the configuration of this embodiment, the swing monorail 4 can be installed even in a narrow space, so unlike the conventional U-shaped fixed rail structure, the rail can change the direction of the lifting machine even in a narrow space. It can be configured as follows. Furthermore, when changing the direction of the lifting machine, it is only necessary to move the lifting machine to the swinging monorail 4 and then swinging the swinging monorail 4. Unlike the conventional method in which the lifting machine is attached to and detached from the monorail, the direction can be changed quickly and easily. I can do it.

Moreover, the roller stopper mechanism 38, 39 opens the roller running section only when the fixed monorail 2 and the swinging monorail 4 are connected, and shuts off the roller running section at other times.
Since this is provided, it is possible to reliably prevent the lifting machine from falling off or falling due to erroneous operation.

Further, since the rail stopper mechanism 34 for positioning the swinging monorail 4 at the monorail connection position is provided, the swinging monorail 4 can be positioned easily and reliably.

Furthermore, since the height of the swing monorail 4 can be adjusted by rotating the swing shaft 6 using the level adjustment lever 24, installation is easy.

Furthermore, since the rotating monorails 4 installed at at least two or more intersections are interlocked with each other, the direction of the lifting machine can be set systematically.

〔Effect of the invention〕

As described above, according to the present invention, the fixed monorails arranged in an intersecting manner and the swinging monorails provided at the intersections thereof are provided, and the lift-N machine can perform necessary direction changes while stopped on the swinging monorails. Therefore, it is possible to easily and quickly change the direction of the lifting machine between multiple rails in a small space.
