Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large open / close roof drive device suitable for driving an open / close roof of a stadium.

[0002]

2. Description of the Related Art A large-span steel roof with a long span in a stadium, as shown in the plan view of FIG.
A large roof of the stadium 1 having an elliptical planar shape is formed by a four-part roof structure having a pair of movable roofs 3. The movable roofs 3 are attached to the lower ends of the rectangular long-span direction. Further, it is possible to travel straight by a plurality of drive carriages and driven carriages, and when the roof is opened, the vehicle travels so as to cover the fixed roofs 2 and opens the central portion of the large roof. Then, the structure of the drive carriage and the driven carriage will be described by taking the drive carriage shown in the side view of FIG. 7 and the front view of FIG. 8 as a representative, and traveling wheels on traveling rails 5 and 6 laid on the bottom and side surfaces of the traveling pit 4. 9 and a horizontal wheel 10, a drive carriage 8a is mounted, and a front and rear portion of the drive carriage 8a is equipped with a motor 18 and a speed reducer 19, respectively.
Further, a pedestal 11 is fixed to a central portion of the drive carriage 8a by a fixing pin 12 perpendicular to a roof traveling direction, and a frame base 1 of a roof lower frame 13 is mounted on the pedestal 11.
4, the drive carriage 8a and the lower roof frame 13 are integrally rigidly connected in a direction perpendicular to the roof traveling direction.

Therefore, in the movable roof 3 having such a driving carriage and a driven carriage, the temperature generated in the span direction of the driving carriage and the driven carriage attached to the lower ends of both ends is affected by the temperature change of the steel roof structure. Due to the amount of horizontal displacement generated by the stress, the driving carriage and the driven carriage are subjected to a temperature load, which affects the running performance thereof.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and avoids the occurrence of temperature load on a traveling carriage mounted on the lower ends of both ends of an opening / closing roof, seismic force, etc. It is an object of the present invention to provide a large-sized open / close roof drive device that exhibits sufficient resistance to a load with a large fluctuation, and can prevent a reaction force fluctuation on the dolly side to prevent a decrease in traveling performance.

[0005]

To this end, the present invention is designed to move and open in a direction perpendicular to the long-span direction by driving a plurality of traveling carriages each having a long-span large steel roof attached to the lower ends of both ends in the long-span direction. In a large open / close roof to be carried out, at least the joint portion between the bogie on one end side and the lower portion of the roof structure is slidably coupled in correspondence with horizontal displacement in a direction perpendicular to the traveling direction of the component due to temperature stress, and the above-mentioned coupling part is also provided. Further, it is characterized in that a buffer means for limiting horizontal displacement due to fast movement is provided.

[0006]

In the large open / close roof drive apparatus of the present invention, when a temperature load is generated due to a horizontal displacement amount of the roof structure which is perpendicular to the roof traveling direction due to temperature stress, the joint portion between the lower part of the roof structure and the carriage is horizontally displaced. Slide in the direction, thereby avoiding reaction force fluctuations on the bogie. In addition, when the reaction force fluctuates rapidly due to seismic force or the like, the shock absorber sufficiently resists the load to eliminate the reaction force fluctuation to the trolley side.

By sliding with 6, the horizontal displacement amount due to temperature stress is released, and it is possible to avoid the temperature load on the driven carriage 7b. Further, when an earthquake occurs in the sliding direction between the lower sliding hardware 15 and the upper sliding hardware 16, the seismic force cannot be counteracted only by the sliding hardware 15, 16 coupling, and the integrated rigid structure shown in FIG. The load is transmitted from the drive carriage 8a and the driven carriage 8b side, and the drive carriage 7a and the driven carriage 7 on this side are transmitted.
Although only b may bear a large seismic force, in this case, by setting a damper coefficient in the hydraulic cylinder 17 that can resist a large movement quickly such as seismic force, The drive carriage 7a and the driven carriage 7b show sufficient resistance against a large load of seismic force, and can act as a fixed against a drastic reaction force fluctuation.
