Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a crossing monorail device that can be applied to a hoist monorail line that runs on the ceiling and conveys articles.

Conventional technology In the past, for example, in a hoist monorail line used for transporting casting ladles, etc., a monorail was used in the main transport direction, which had a large transport capacity and frequency, and a monorail in an auxiliary transport direction, which had a small transport capacity and frequency. When the lines intersect slightly due to the structure, a two-stage monorail crossing monorail system shown in FIGS. 3 and 4 is often adopted. In this crossing monorail device, the upper rail 2a of the auxiliary line monorail 2 is fixedly arranged below the main line monorail 1 with a slight distance left until it intersects with the main line monorail 1, and the trolley 3 and fishing wheel are attached to this upper rail 2a. 4, the lower rail 2b is provided so as to be runnable,
In addition, a hoist 6 is provided on the lower rail 2b via a trolley 5 so that it can run, and the upper rail 2 is moved when necessary.
A lower rail 2b is extended from the tip of a, so that the auxiliary line monorail 2 slightly intersects the main line monorail 1.

Problems to be Solved by the Invention By the way, in the two-stage monorail crossing monorail device, the lower rail 2b must be constantly running together with the hoist 6, which requires a large amount of power and is costly. Further, since the lower rail 2b runs on the upper rail 2a, when the lower rail 2b runs on a curve, the radius of curvature of the upper rail 2a must be increased, which results in a large loss of ceiling space. Furthermore, since the lower rail 2b overhangs the tip of the upper rail 2a, the lower rail 2b inevitably becomes unstable. Furthermore, since the work was carried out in two stages, workability was poor and work efficiency was not improved.

Means for Solving the Problems This invention consists of one side of intersecting monorails consisting of a fixed rail and a movable rail, the fixed rail and the movable rail being connected in abutting manner below the other monorail, and the movable rail can be moved in the longitudinal direction of the rail.

Function: This invention allows mutual transportation of both monorails by moving the movable rail as necessary and separating the movable rail from the fixed rail to allow passage of the other hoist. .

Embodiment FIGS. 1 and 2 show a crossing monorail device according to this invention. In this drawing, 11 is a main line monorail, which is installed on a ceiling beam 12 that is part of the ceiling. An auxiliary line monorail 13 is arranged below the main line monorail 11 so as to slightly intersect with the main line monorail 11, and is composed of a long fixed rail 14 and a short movable rail 15. The fixed rail 14 connects the rod 1 with a slight distance left until its tip intersects with the main line monorail 11.
6 to the ceiling beam 12, and a receiving bush 14a is fixed to the upper surface of the tip. The movable rail 15 is disposed at the tip of the fixed rail 14 in abutting manner, is fixed to a bogie 19 that is movably provided on a bogie rail 18 of a bogie support frame 17 fixed to the lower part of the ceiling beam 12, and is attached to the top surface of the tip. A support pin 15a that fits into a receiving bush 14a of the fixed rail 14 is fixedly provided on the support pin 15a. 20 is bogie rail 1
The tip of the piston rod 21 is engaged with the bogie 19 by a cylinder for running the bogie fixedly attached to the bogie 8, and the extending and contracting motion of the piston rod 21 causes the bogie 19 to run along the bogie rail 18 to move the movable rail 15 as shown in the figure. I try to move back and forth from side to side. A trolley 22 is movable on the fixed rail 14 and the movable rail 15, and is equipped with a hoist 23 for hoisting articles.

In the above configuration, when carrying the main line monorail 11, the piston rod 21 of the bogie running cylinder 20 is retracted and the bogie 19 is moved backward along the bogie rail 18, that is, to the left in the figure. Then, the moving rail 15 retreats together with the trolley 19,
As shown in FIG. 2, the fixed rail 14 and the movable rail 15 are separated, and there are no obstacles directly below the main line monorail 11, allowing transportation on the main line monorail 11. Next, when transporting on the auxiliary line monorail 13, the piston rod 21 of the bogie running cylinder 20 is extended and the bogie 19 is moved forward along the bogie rail 18, that is, to the right in the figure. 15 moves forward together with the truck 19, and as shown in FIG. 1, the fixed rail 14 and the movable rail 15 are connected in abutting state.
At this time, the support pins 15a of the movable rail 15 are fitted into the receiving bushes 14a of the fixed rail 14 to guide and center the fixed rail 14 and movable rail 15 together, and further stabilize the movable rail 15 by supporting both ends. let In this state, the trolley 22 equipped with the hoist 23 can be transferred from the fixed rail 14 to the movable rail 15, allowing transportation on the auxiliary line monorail 13.

Effects of the invention This invention consists of an auxiliary line monorail that intersects the main line monorail, consisting of a fixed rail and a moving rail, and connecting the fixed rail and the moving rail in abutting manner below the main line monorail,
The rail connections can be separated as needed, allowing the hoist to run on its own, saving power and saving on ceiling space since the radius of curvature of the rail is small even when the hoist is running on curves. Furthermore, the structure is simple and maintenance is easy, and the workability is excellent, so that the work efficiency can be improved. In addition, by connecting the movable rail to the fixed rail in abutting manner, both ends of the movable rail can be supported, so that stable conveyance can be performed on the movable rail.
