[Purpose of the invention]

The present invention was made in view of these circumstances, and provides a monorail branching device that allows a lifting machine to easily and quickly change direction between multiple rails despite a narrow space, and that prevents the lifting machine from falling off when changing direction. The purpose is to provide.

[Summary of the invention]

In the monorail branching device according to the present invention, there is a fixed monorail in which a plurality of rail members are arranged in the same plane in a cross-shaped manner, and a fixed monorail arranged at the intersection of the fixed monorails with a vertical turning axis. The lifting machine is equipped with a rotating monorail that can change the direction of the rail, and the lifting machine can make the necessary change of direction while stopped on the rotating monorail, so that it can easily move from one fixed rail to the other. ing.

〔Example〕

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

FIG. 1 shows an example of a schematic arrangement configuration of a monorail, in which a plurality of fixed monorails 2 are arranged vertically and horizontally, and a swinging monorail 4 is arranged at the intersection of each fixed monorail 2 so as to be able to swing via a swing axis 6. has been done. 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 is made of a rail member with a roughly shaped cross section (FIG. 6). The lower side 2a of this rail member
One side 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). Swivel guide rail 4
consists of a rail member having the same cross-sectional shape (approximate shape) as the fixed monorail 2. The lower side 4a of this rail member
One side is used as a roller guide for the lifting machine, and the upper side 4
The longitudinal and widthwise center portions of b are supported by the building ceiling 12 by a pivot shaft 6 (FIG. 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 has a threaded portion 22 at the top screwed into the fixing nut portion 16a of the holder 16, and by adjusting the screwing amount, the height level of the support shaft 18 and thus the rotating monorail 4 can be adjusted. Level adjustment is performed by rotating the support shaft 18 during installation via an L-shaped level adjustment lever 24 inserted into the support shaft 18. When the heights of the swing monorail 4 and the fixed monorail 2 match, the tip 24a of the level adjustment lever 24 is fixed to the holder 16 by welding or the like.

The housing 20 is connected to the support shaft 1 as shown in FIG.
8 via a radial bearing 26 and a thrust bearing 28. The housing 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 ends 4c of the swinging monorail 4 and the ends 2c of each fixed monorail 2 adjacent thereto are mutually formed in an arc shape, allowing the swinging monorail 4 to swing smoothly, and also allowing the ends to touch each other when the swinging monorail 4 is stopped. are arranged in close proximity. 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. Roller stop mechanisms 38 and 39 are provided which open 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 It is composed of a rotating ring 44 that is pressed and held downward by a spring 42, and a wave-shaped guide member 48 that protrudes from the upper side 2b of the fixed monorail 2 and receives the rotating ring 44. The corrugated guide member 48 has a recess 48a into which the rotating wheel 44 pressed by the spring 42 sinks when the swinging monorail 4 swings to a position where it is in series with the fixed monorail 2, so that the swinging monorail 4 is stopped and held at this position. It's getting old. The operator should know in advance the resistance force when the rotating wheel 44 passes through the convex portion 48b in front of the concave portion of the corrugated guide member 48, and take into consideration the output of the swing drive motor (not shown), etc. By operating the spring force adjustment nut 50 of the rotating wheel pressing spring 42 provided on the coupling arm 40, adjustment is made so that a smooth locking force for the monorail 4 can be obtained.

Further, the roller stopper mechanisms 38 and 39 are connected to each vertical side 2 of the fixed monorail 2 and the rotating monorail 4.
d and 4d, respectively. As shown in FIG. 6, the roller stopper mechanism 38 on the fixed monorail 2 side includes a stopper 54 that is swingably suspended from one side of the vertical side 2d of the fixed monorail 2 via a horizontal support shaft 52, and a support shaft. Stopper 54 via 52
A stopper operating lever 56 is provided to be able to operate integrally with the fixed monorail 2 and protrudes upward from one side of the fixed monorail 2, and a leaf spring is attached to the fixed monorail 2 via a spring seat 58 and presses the stopper 54 to one side of the fixed monorail 2. It consists of 60. In the roller stopper mechanism 38 of the fixed monorail 2 which is in a disconnected state from the rotating monorail 4, the stopper 54 is connected to the leaf spring 6.
0, it protrudes to one side of the vertical side 2d, and becomes in a state of preventing the rolling of the roller 36 of the lifting machine (the state indicated by the solid line in FIG. 6). In addition, the rotating monorail 4
In the roller stopper mechanism 38 of the fixed monorail 2 that is connected to the
When the engaging arm 40 protruding from the side pushes the stopper operating lever 56 to one side (in the direction of arrow A), the stopper 54 resists the elastic force of the leaf spring 60 and moves to the vertical side 2d side of the fixed monorail 2. The lifting machine enters a state in which the roller 36 of the lifting machine is allowed to roll (the state indicated by the imaginary line in FIG. 6).

On the other hand, as shown in FIG. 7, the roller stopper mechanism 39 on the swinging monorail 4 side includes a stopper 64 that is rotatably suspended from one side of the vertical side 4d of the swinging monorail 4 via a horizontal support shaft 62, and a support. axis 62
It consists of a stopper actuating lever 66 that is movable integrally with the stopper 64 via the lever and rises to near the bottom of the upper side 4b of the rotating monorail 4, and a leaf spring 68 that presses the stopper 64 to one side of the rotating monorail 4. . When the swinging monorail 4 is not aligned in series with the fixed monorail 2, that is, when it is in the middle of turning, the stopper 64 is pressed by the leaf spring 68 and protrudes to one side of the vertical side 4d, preventing the rotation of the roller 36 of the lifting machine. Also, the rotating monorail 4 turns in one direction (the direction of arrow B) and, for example, the fixed monorail 2 (2A) placed toward the right in FIG. When the connection is established, the engagement pin 70 protruding from the vertical side 2d of the fixed monorail 2 (2A) connects to the stopper operating lever 66 through the through hole 72 formed on the vertical side 4d of the rotating monorail 4. As a result, the stopper 64 retracts toward the vertical side 4d of the rotating monorail 4 against the elastic force of the leaf spring 68, and the roller 3 of the lifting machine
6 is allowed to roll (the state indicated by the virtual 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. 2 (2
The presser arm 74 protruding from the vertical side 2d of B) 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 leaf spring 68. As in the case of turning in one direction, the lifting machine is in a state where the rollers 36 of the lifting machine are allowed to roll (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, the rotating monorails 4 to be interlocked with each other
Brackets 78 are protruded from both ends of the upper side 4b, and each bracket 78 is connected to a link arm 8, respectively.
Connected by 0. The end of the link arm 80 extends beyond the bracket 78, and the extended end 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. Note that each link arm 80 has
An adjustment spring 83 is provided for positioning the interlocking swing monorail 4 at the time of initial installation. After the spring 83 is set to the initial position, it is locked in a non-extensible state, creating a rigid structure in which the length of the link arm 80 is constant.

In addition, the fixed monorail 2 and the rotating monorail 4
Trolley buses 84 are provided in parallel with each other.
This trolley bus 84 is connected and disconnected in the same direction as the rotating monorail 4. Trolley bus 8 attached to rotating monorail 4
4 is provided with a center feed box 86.

FIG. 9 shows an example of the use of the monorail branching device configured as described above. That is, the rotating monorail 4 is provided at each intersection branch of the three parallel fixed monorails 2A1...2A3 and the fixed monorails 2B1 and 2B2 intersecting these so that they are in the same rotating state via the interlocking mechanism 8. 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 rotating monorail 4 is aligned with the direction of the fixed monorail 2A1, each roller stopper mechanism 38 of the fixed monorail 2A1 and the rotating monorail 4,
39 is in a state where the lifting machine is allowed to run on its rollers. Therefore, the lifting machine is suspended on the swinging monorail 4 and turned, for example, 90 degrees counterclockwise to the state shown in FIG. 2B. Roller stop mechanism 39 during turning
This keeps the lifting machine from falling from the rotating monorail 4. After turning, the roller stopper mechanisms 38 and 39 will be in the roller release state again, so the lifting machine can be moved to the fixed monorails 2B1 and 2B as shown in Figure C.
Move it vertically across B2. After that, when the lifting machine is placed on the rotating monorail 4 at a predetermined position, the rotating monorail 4 is rotated in the opposite direction to the initial direction as shown in FIG. Have 2A3 run the lifting machine in the opposite direction from the beginning. Note that the same applies to the case of moving to the intermediate stationary monorail 2B2.

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. In addition, 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, fixed monorail 2 and rotating monorail 4
The roller running section is opened only when the
Since roller stopper mechanisms 38 and 39 are provided to block the roller running section at other times, it is possible to reliably prevent the lifting machine from falling off or falling due to erroneous operation.

In addition, a rotating monorail 4 is installed at the monorail connection position.
Since the rail stopper mechanism 34 for positioning is provided, the swinging monorail 4 can be easily and reliably positioned.

Furthermore, the level adjustment lever 24 allows the rotation axis 6 to
Since the height of the rotating monorail 4 can be adjusted by rotating the monorail 4, the installation process 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, fixed monorails arranged in an intersecting manner and a swinging monorail provided at the intersection thereof are provided, and the lifting machine can perform necessary direction changes while stopped on the swinging monorail. Therefore, it is possible to easily and quickly change the direction of the lifting machine between multiple rails in a small space.

Further, in the present invention, the fixed monorail is provided with a first stopper member, and the rotating monorail is provided with a second stopper member, and the first and second stopper members operate during non-contact, such as during a direction change, to lift the vehicle. Since the rollers of the heavy equipment are locked, it is possible to prevent the lifting equipment from falling off the monorail when changing direction.

Furthermore, since the second stopper member is also provided on the swinging monorail, the direction can be changed while the lifting machine is placed on the swinging monorail. Thereby, the direction of a large number of lifting machines can be changed efficiently.

Further, in the present invention, a holding mechanism is provided on the fixed monorail and the swinging monorail, and when the fixed monorail and the swinging monorail are connected, the engaging member of the holding mechanism attached to the swinging monorail is the guide member of the holding mechanism fixed to the fixed monorail. Since it engages and comes into pressure contact with the corrugated surface of the rotating monorail, it becomes easy to position the rotating monorail to the connection position, and the rotating monorail can be reliably and stably connected to the fixed monorail.
