Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a branching device for a suspended vehicle.

Conventionally, the type of branching device shown in Figure 1 has been used for this type of suspended vehicle. In FIG. 1, a is a fixed girder, and a' is a running surface disposed on the left and right sides of a gap provided at the bottom of the fixed girder a. A truck runs on the same running surface a', and a vehicle is suspended from the truck through the gap. b is a movable rail that is rotatably supported inside the fixed girder a on a pivot shaft c fixed to the fixed girder a, and has a running surface forming an extension of the running surface at the bottom thereof. There is. b' is the tip of the movable rail b and does not have a running surface at the bottom. d is a correction rail that is pivotally supported by a pin d' on the running surface on the merging side of the branching part, and that aligns the deviation between the running surfaces of the movable rail b and the fixed girder a. e is a crimping device that crimps and fixes the movable rail b and the correction rail d to the fixed girder a, and i is a hydraulic cylinder that drives the crimping device e. f is a hydraulic cylinder that turns the movable rail b, g is a hydraulic cylinder that pulls up the movable rail b, and h is a hydraulic cylinder that swings the correction rail d. The branching operation is performed by moving the movable rail b from one running surface to the other running surface. First, hydraulic cylinder i is activated to unlock the crimping device e, then hydraulic cylinder g is activated to pull the movable rail b upward, and then hydraulic cylinders f and h are activated to move the movable rail b and correction rail d. After swinging and moving to a predetermined position, actuate the hydraulic cylinder g to lower the movable rail b to the running surface of the fixed girder, then actuate the hydraulic cylinder i to lock the crimping device and correct it to the movable rail b. Fix rail d to the fixed girder.

In this way, in conventional branching devices, branching operations are performed using hydraulic cylinders dedicated to each component, which increases the number of hydraulic piping, complicates the operation control mechanism of the hydraulic device, and reduces the operating time of each hydraulic cylinder. Combined with the fact that the branches are added sequentially, there is a drawback that the time required to turn the branch increases. In addition, many hydraulic cylinders are installed within fixed girders and have many hydraulic piping, so they may not operate due to wear on the hydraulic cylinder packing, deterioration of the hydraulic piping rubber hose, or loosening of the hydraulic piping joints due to track vibration. Oil leaks to the outside, making it dirty, which poses a problem in terms of environmental pollution, and increases the number of maintenance and inspection steps. Furthermore, the drive arm for swinging the movable rail using a hydraulic cylinder protrudes behind the pivot axis of the movable rail, and due to the location, this drive arm has to pass through the pillar that suspends the fixed girder, which poses a problem in terms of strength. occurs.

The present invention provides a movable rail whose one end is pivotally supported on the branch side end of a fixed girder and is swingable in the horizontal direction, and a movable rail that is provided on the left and right running surfaces of the fixed girder so as to be swingable in the horizontal direction about the merging side end, respectively. In a suspension vehicle branching device consisting of a pair of correction rails that align the movable rail and the running surface of a fixed girder, an opening extending along the sliding direction of the movable rail is opened on the upper surface of the outer wall of the fixed girder, and one end is connected to the movable rail. A traveling rail for a traveling trolley is disposed along the opening and supports the other end of the lifting connecting rod protruding from the opening, which is connected to the upper middle part of the rod, while always biasing upward with a spring, and a correction rail is provided. A first device that swings the carriage via a link mechanism and drives the traveling carriage via the link mechanism.
and a second electric drive device that drives, via a link mechanism, crimping hardware that presses and fixes the movable rail and the correction rail to the fixed girder, respectively, are arranged on the upper surface of the outer wall of the fixed girder. The object thereof is to provide a branching device which eliminates the above-mentioned drawbacks of the conventional art, speeds up the switching time, and is easy to maintain and inspect.

The present invention is configured as described above, and in the branching operation, first, the second electric drive device moves the crimping hardware upward to free the movement of the movable rail and the correction rail. At this time, the movable rail floats upward due to the action of the spring. Then, the actuating arm is driven by the first electric drive device to swing the movable rail via the traveling truck and the lifting connecting rod, and swing the correction rail via the link mechanism to set each to a predetermined position. . In this state, the crimping hardware is lowered by the second electric drive device, and the movable rail and the correction rail are pressed and fixed.

As described above, according to the present invention, the number of drive devices is greatly reduced and the number of drive operations is halved, so the operation control mechanism of the drive device can be simplified, and the amount of time lag between each operation is reduced, so branch switching is possible. It takes less time. The main components are installed on the outer wall (shelf) of the fixed girder, and the drive device is electric, making it easy to access each device, eliminating oil leaks like in the past, and making maintenance and inspection easier. In addition, the central part of the movable rail is pulled upwards by a spring via a lifting connecting rod, and the lifting connecting rod is driven to swing, so that the fixed part, which is the main strength member, is not used as in the past. There is no need to provide a through hole in the pillar supporting the girder, increasing safety.

The present invention will now be described in detail with reference to the most preferred embodiment shown in FIGS. 2-8. In the figure, 1 is a movable rail, and 2 is a pivot shaft attached to the movable rail 1 and rotatably supported by a fixed girder 9. Reference numeral 3 denotes a correction rail, which is attached to the left and right running surfaces 9' of the fixed girder 9 so as to be swingable about the merging side end. Reference numeral 4 denotes crimping hardware installed on each side of the fixed girder 9, and the crimping hardware 4 is pulled upward when the movable rail 1 and correction rail 3 are turning, and when the turning is completed, both are pulled up. When positioned at a predetermined position, both are pressed downward to prevent movement of the rail when the vehicle is running. Reference numeral 5 designates a lifting connecting rod whose one end is attached to the upper end of the center portion of the movable rail 1 and whose other end is provided to protrude from the fixed girder 9 shed. Reference numeral 8 denotes a traveling rail provided along the opening of the fixed girder, which serves as a movement path for the lifting connecting rod 5 as the movable rail 1 swings. 6 is the same running rail 8
It is a traveling trolley that runs above. 7 is the above-mentioned lifting connection rod 5
The spring 7 is a spring interposed between the carriage 6 and the traveling carriage 6, and the spring 7 urges the lifting connecting rod 5 upward. 12
An operating arm is supported on the upper roof of the fixed girder 9 so as to be swingable about a pivot shaft 12', and one end of the operating arm 12 is attached to the traveling carriage.
Reference numeral 10 denotes an electric drive device which rotates a transmission shaft 14 by means of a connecting rod 13, operates link mechanisms 15 disposed on the left and right sides of the transmission shaft 14, and swings the correction rail 3. At the same time, the operating arm 12 is moved by the connecting rod 13 via the escape crank 11 to move the traveling carriage 6, and the movable rail 1 is swung via the lifting connecting rod. 16 is another electric drive device, which rotates the transmission shaft 17 to drive the left and right two
The crimp fitting 4 is moved up and down via a set of link mechanisms 18.

This embodiment is constructed as described above, and when branching from the straight line position shown in FIG. 4 to the branch position shown in FIG. 18 is actuated to move the crimping hardware 4 upward and free the movable rail 1 and correction rail 3. Next, the electric drive device 10
is driven to move the connecting rod, and one side swings the movable rail 1 via the escape crank 11, the operating arm 12, the traveling truck 6 and the lifting connecting rod 5,
At the same time, the correction rail 3 is swung via the transmission shaft 14 and the link mechanism 15 on the other hand. When the movable rail 1 and the correction rail 3 are in the predetermined positions, the electric drive device 10
is stopped, and then the electric drive device 16 is operated in the opposite direction to the front, and the crimp fitting 4 is operated downward to press and fix the movable rail 1 and the correction rail 3.

In this way, according to this embodiment, the movable rail and the correction rail are oscillated by one electric drive device using the link mechanism, and the vertical movement of the crimping metal is carried out by one electric drive device. Since the spring automatically lifts the rail, the drive source and drive operations are halved compared to conventional models. This simplifies the operation control mechanism of the drive, reduces the amount of time lag between each operation, and reduces the time required to turn over a branch. In addition, since an electric drive device is used, it is easy to control the speed of acceleration and deceleration during a fall, and it is possible to reduce the impact noise during a fall and shorten the time for falling. Since most of the drive mechanism is located on the outer wall of the fixed wall, maintenance and inspection can be performed during the day when the vehicle is in operation, and maintenance and inspection are also facilitated since it is easily accessible to workers. Furthermore,
Since the movable rail is swung by moving the center part of the movable rail, there is no need for the drive arm to protrude behind the pivot axis as in the conventional case, and this allows for a common hole in the column that supports the fixed girder, which is the main strength member. It is safe and easy to construct, as there is no need to install a
