Description

[Detailed Description of the Invention] The present invention relates to a device for moving a guide girder forming a guide track of a monorail vehicle.

Traditionally, the track of a monorail vehicle consists of a running girder A, a guide girder B, etc., as shown in Figure 1.
is fixed to the fixed guide girder C with a bolt D.
Therefore, if the guide girder B gets in the way when inspecting the monorail, inspecting the bogie of the monorail vehicle at the inspection and repair shop, or replacing the running wheels or guide wheels, remove the bolt D and guide the guide girder B using a crane, etc. Girder B had been removed. Therefore, the installation and removal work of the guide girder takes time and is inefficient, requires equipment such as a crane, and the installation and removal work is dangerous. Furthermore, there are many other problems, such as the need for extra space to place guide girders during replacement of running wheels, etc.

The present invention provides a guide girder for the track of a monorail vehicle, which consists of a running girder that guides the running wheels of the monorail vehicle, and a pair of guide girders that are installed on both sides of the running girder and guide the guide wheels of the monorail vehicle. A portion of the notch is cut out in the longitudinal direction, and the notch is formed to be freely undulating on the outside of the running girder via a hinge, and the other end of a fluid cylinder whose one end is connected to the stationary part via a pin joint is attached to the guide girder. The guide girder is connected to the opposite guide surface via a pin joint, and is constructed so that the guide girder is raised and lowered by the expansion and contraction of the fluid cylinder. The present invention aims to provide a guide rail moving device that eliminates the problems encountered.

Since the present invention is constructed as described above, by simply operating the fluid cylinder girder, the traveling wheels and guide wheels can be replaced by simply raising and lowering the guide girders at their installation positions, without having to use a crane or the like to attach or remove the guide girder as in the past. I can work. Therefore, not only can the equipment cost be greatly simplified, but also the work of replacing wheels etc. can be carried out efficiently and safely.

Next, the present invention will be described with reference to the illustrated embodiment shown in FIGS. 2 and 3.

The monorail track is composed of a running girder 1, a guide girder 2, a fixed guide girder 3, etc. The running girder 1 carries the entire load of the monorail vehicle, and the running wheels 8 run on it. The guide girder 2 guides the guide wheel 9 with the guide surface 2a, as in the conventional case, and restricts the left-right movement of the monorail vehicle. As shown in the figure, the guide girder 2 is hinged to the outer edge of the running girder 1 by several hinges 5 so as to be able to rise and fall freely. Reference numeral 4 denotes a fluid cylinder that raises and lowers the guide girder 2, and one end of the fluid cylinder 4 is connected to the inspection walkway surface 1.
The other end is connected to the stationary part 11 located on the lower surface of the guide beam 2 via a pin joint 4a, and the other end is connected to the opposite guide surface 2b of the guide beam 2 via a pin joint 4b. When the guide girder 2 is erected, it is prevented from falling down by a latch 6 rotatably attached to the fixed guide girder 3.
When it is laid down, it is accommodated in a pocket provided in the inspection walkway surface 10, as shown in FIG. 3, and is used commonly as the inspection walkway surface.

In this embodiment, when moving the guide girder 2 for inspection and replacement of the traveling wheels 8, etc., first remove the latch 6, supply and discharge pressure fluid to and from the fluid cylinder 4 to extend it, and then move the guide girder 2. Lay it down and store it in the pocket described above.

When raising and lowering the guide girder 2, the guide girder 2 is raised and lowered using the opposite operation procedure.

In this embodiment, as described above, the guide girder 2 can be raised and lowered simply by removing the latch 6 and operating the fluid cylinder 4. Therefore, the movement of the guide girder 2 does not require the use of a crane or the like, which is dangerous as in the past, and can be done by one person. This can be done easily and safely, and has excellent practical effects such as eliminating the need for space for ornaments on the guide girder 2.
