Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) This invention is a mobile device that is installed on a large-scale building such as a baseball stadium or other sports building and covers it in an openable and closable manner. It relates to a moving track '4 & mushroom provided at the running end of the roof.

(Background of the invention) In large buildings used for baseball stadiums, track and field stadiums, etc.
A movable roof has been installed on top of the building for the purpose of regulating lighting and temperature, and protecting the inside of the building in rainy weather, allowing the competition to be viewed in conditions as close to natural as possible on sunny or warm days. However, it is hoped that the roof can be moved and closed if necessary.

In order to meet these demands, the present inventors have previously developed the third
We have developed the retractable suspended roof shown in the figure.

In the figure, 1 is the outer wall of a cylindrical building, 2 is the outer wall 1
At the top, there is a fan-shaped folding hanging roof that is divided into six radial sections from the center of the building's ridge.

Each hanging roof 2 can be folded and unfolded from a point 28 at the center of the roof provided at the center O of the ridge, and its eave side end can be moved along a beam 10 provided on the outer wall 1 of the building. It contracts and expands in a fan shape.

Each suspended roof 2 is maintained in a suspended state by suspending a suspension wire 4 between the top of the ball 3 erected on the outer wall 1 of the building and the central portion 28 of the roof.

In the figure, each suspended roof 2 is shown in a completely closed state, and each suspended roof 2 has an outer building wall 1 with its roof surface expanded.
The upper surface of the container is covered with an umbrella shape at a predetermined slope.

In order to open the inside of the building from this state, each suspended roof 2 is folded with the central part of the roof serving as a key point of a fan, and the eave side part of each suspended roof 2 is concentrated in one place at the position of the pole 3. Next, each suspended roof 2 is lifted up by the suspension wire 4 to separate each suspended roof 2, and then rotated, and the beam 1a
By installing it in the center of the roof, it will be completely open. In addition, in the figure, the reference numeral 5 is a support stay that holds the ball 3.

(Problems to be Solved by the Invention) In order to realize this type of structure, - a mobile traveling device is provided that efficiently moves the opening and closing ends of each suspended roof 2 and allows each suspended roof 2 to be folded and unfolded; is necessary.

The conditions required for this mobile traveling device are, first, that the entire load of each suspended roof 2 can be received at the eave side end;
Since this load generates horizontal and vertical component forces depending on the roof slope, it is necessary to have sufficient durability and to maintain the component forces and distribute the load.

Further, if the traveling drive device is made to share these loads, the driving power thereof becomes extremely large, so it is not preferable to make the power device share this load.

The purpose of this invention is to satisfy the above conditions by providing stability and durability, distributing the load, and roughly providing only the traction function for movement to the power unit. The present invention provides a mobile traveling device that can reduce driving power.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides at least a pair of movable roofs installed along the running edge of the movable roof and orthogonally arranged with an inclination according to the root slope. a main rail; a guide rail arranged horizontally and parallel to the side of the main rail;
a guide wheel that is connected to a running end of the movable roof and rolls on each of the main rails to transmit a force corresponding to the load of the movable roof to each of the main rails; It is characterized by comprising a traveling drive device that runs, and a connector that connects the traveling drive device and the traveling end of the movable roof in the transport direction.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 is a sectional view of a mobile travel device according to the present invention, and FIG. 2 is a perspective view of the same device, partially in section.

Each figure shows the application of this invention to the retractable hanging roof of the previous J-ho.

The suspended roof 2 is a lightweight steel membrane structure, and an end fitting 22 connected to a main beam 20 for supporting the roof membrane is provided at the end of the eave side. A track bed base 30 is laid on the pole 1a facing the eave-side end of the end fitting 22 along the circumferential direction of the beam 1a. The side and top surface of the track bed base 30 on the end fitting 22 side have an inclination equal to the roof slope of the suspended roof 2, and the upper and side T-shaped frames 32 installed perpendicular to this inclination are orthogonal. A convex main rail 36 is arranged and fixed on the surface of each T-shaped frame 32 via a pillow plate 34.

The lower edge of the end fitting 22 is notched in correspondence with each of the main rails 36, and an angle 3 is attached to this notched portion.
8 is welded, and a frame 4 is also welded to the inner circumference of the frame 4.
The location of 0 is fixed.

A substantially U-shaped truck 42 is fixed to the frame 40 and is positioned opposite to each of the main rails 36 . Guide wheels 44 that roll in contact with each of the main rails 36 are supported on this truck 42 .

In addition, on the upper side of the guide wheel 44 located on the side,
A tapered cone-shaped flange 44a is integrated, thereby receiving the vertical load of the suspended roof 2 and preventing the guide wheel 44 from falling off.

Further, a tapered cone-shaped flange 44a is also formed on the side surface of the upper guide wheel 44 on the end fitting 22 side, and the axial inner cylinder of the main beam 20 receives heavy horizontal component force on this flange surface.・Furthermore, the upper cart 4
An L-shaped reinforcing member 46 and an angle member 48 for preventing floating are attached to the side surface of the roof 2. By placing the lower end of this angle member 48 facing the lower surface of the pillow plate 34, the suspension roof 2 is prevented from floating. Prevents climbing.

Further, a horizontal arm 50 is provided on the eave-side side surface of the track bed base 30.
are welded together, and a guide rail 52 with a T-shaped cross section parallel to the main rail 36 is laid at the end of this arm 5°, and a pin rack 54 is arranged and fixed at the center of the upper surface.

A traveling drive device 56 is arranged on the guide rail 52.

This travel drive SjJ device 56 has a case 5 whose bottom surface is open.
62, a motor 564 disposed within the case 562,
A sprocket 568 is rotatably connected to the output shaft of the motor 564 via a plurality of reduction gear groups 566 and meshes with the pin rack 54; It consists of a pair of wheels 570 for guiding and preventing lifting, which freely touch and sandwich the wheel.

The traveling drive device 56 and the suspended roof 2 are connected to each other in the first
As shown in the figure, it consists of a combination of a connecting plate 60 that protrudes from the side surface of the upper truck 42 and two locking plates 62 that protrude from the side surface of the case 562 of the travel drive device 56 and sandwich the connecting plate 60. ing.

Each plate 60, 62 is free in the vertical and horizontal directions, and is connected only along the direction of each rail 36, 52.

Therefore, the load of the suspended roof 2 is not applied to the traveling drive device 56 at all, and the load is exclusively passed through each guide wheel 44.

As a result, only the main rail 36 will bear the load.

Moreover, the pair of guide wheels 44 on the side side mainly share the horizontal component of the load in the axial direction of the main beam 20 of the suspended roof 2,
In addition, the guide wheels 44 on the upper side share the vertical component force,
Each component force is transmitted to each main rail 36.

In the above configuration, the traveling drive device 56 moves by itself on the guide rail 52, so that the suspended roof 2 moves while rolling the wheels 44 provided at the ends thereof along the surface of each main rail 36, The eaves side edge can be folded or unfolded along the running direction.

In this embodiment, the present invention is applied to a retractable suspended roof, but it can also be applied to a movable retractable roof as shown in FIG. 4, for example.

This movable retractable roof has a plurality of layers of arch-shaped roof 10 provided on the upper part of the outer wall of the building, and both ends of the roof 10 are installed parallel to the beam 1a of the outer wall 1. Therefore, a plurality of mobile traveling devices having the same configuration as described above can be arranged in a straight line at both ends (the portions surrounded by A in FIG. 4).

(Effects of the Invention) As described above in detail with reference to the embodiments, according to the present invention, the load is distributed according to the roof slope of the movable roof, so the load can be distributed. There are no problems with the strength of the rails due to concentration of the rails in one place, and there is no large load on the shaft of the guide wheel, resulting in great stability.

Further, since no roof load is applied to the traveling drive device and only the traction force is required, the driving power can be small.

Furthermore, in this invention, since the travel drive device and the travel end of the movable roof are connected only in the transport direction, it is possible to deal with misalignment during travel.
