Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof moving device applied to a vertically movable retractable roof.

(Prior art) In conventional vertically movable retractable roofs, a winch is generally installed below the outer end of the beam supporting the movable roof in order to move the heavy roof vertically against gravity. ,
The wire rope unwound from the winch was guided to the top of the beam using a sheave or the like, and at the top, it was further looped around the sheave, and the tip was latched to the movable roof while being reversed downwards of the beam.

This allowed the winch to be rotated in forward and reverse directions to raise and lower the movable roof.

(Problem to be Solved by the Invention) However, in the conventional moving device described above, the traction reaction force when moving the roof acts on the shaft supporting the sheave at the part of the sheave that changes the traction direction of the wire rope. This requires a sheave and winch installation structure that can sufficiently withstand this reaction force, which has the disadvantage of increasing the weight of the structure.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to solve the problem that the structure of the entire retractable roof has a strength problem due to the structure of the moving device required to open and close the movable roof. The object of the present invention is to provide a retractable roof moving device.

(Means for Solving the Problem) In order to achieve the above object, a retractable roof moving device according to the present invention is provided on the back surface of a vertically movable movable roof, and has a chain stretched in the direction of the moving axis of the roof, and A gear for opening and closing, which engages with this chain and rotates, is fixed to the beam that supports the moving roof. Furthermore, in order to move a stacked vertically movable retractable roof with a two-tiered movable roof structure, the movable roof is made into a lower movable roof, and an upper movable roof is stacked on top of it, and both are driven to open and close. In a movable roof that can be moved up and down, one end of a rope or belt is fixed to the base end of the beam that supports these roofs, and this is passed around the sheave attached to the tip of the lower movable roof while moving it downward. It was inverted onto the roof and the other end was fixed to the lower end of the upper movable roof.

(Function) When the opening/closing drive gear is driven to rotate, the chain that engages with this gear moves in accordance with the direction in which the gear rotates.

The moving roof that moves in this way is referred to as the lower moving roof,
When another movable roof is movably stacked on top of the lower movable roof and the lower movable roof is moving toward the base end of the beam supporting the movable roof, the rope, belt, etc. Since the length between the tips is the shortest, the part beyond the sheave at the tip of the lower moving roof is reversed and folded back, and as this folded part becomes longer, the upper moving roof is Under its own weight, it moves on the lower moving roof towards the base end of the beam and becomes superimposed on the lower moving roof.

Conversely, when the lower moving roof is moved upward, the ropes, belts, etc. from the tip end are wound back toward the lower moving roof and change linearly, so that the upper moving roof is moved upward. The roof is moved towards the top of the beam. That is, when the lower movable roof is moved in the vertical direction, the upper movable roof also opens and closes in a corresponding manner.

(Example) FIG. 1 shows the side surface of a vertically movable opening/closing roof. A movable roof 1 that opens and closes moves on guide rails attached to the surface of an arch beam 2 while being directed by running wheels or the like. The motive power for the movement is provided by the moving device described below.

First, a chain 3 is stretched on the back surface of the moving roof 1 along the moving axis. This chain 3 is stretched linearly from the upper end to the lower end of the movable roof 1. Also, chain 3
In order to keep the slack of
Chain supports for supporting the chain 3 on the arch beam 2 are also provided with rollers 5 intermittently.

The middle part of this arch beam 2 is located at the tip of the arch beam 2 when the movable roof 1 has descended to the base end of the arch beam 2, that is, when the movable roof 1 is in an open state. Chain 3 so that the teeth slightly protrude from the surface.
A hydraulic motor 7 integrated with a sprocket 6 for rotating a sprocket 6 that engages with the sprocket 6 is arranged in parallel on the left and right. In order to drive this hydraulic motor 7, hydraulic piping 8 is arranged along the arch beam 2, and its hydraulic unit 9
is installed at the base end of the arch beam 2.

Therefore, when the hydraulic motor 7 is driven to rotate, the chain 3 of the moving roof 1 is driven by the sprocket 6 in the direction of rotation of the sprocket 6. The chain holder is supported by the rollers 5 and pressed downward by the chain presser rollers 4, so that the slack in the middle of the chain 3 does not easily come off at the position where it engages with the sprocket 6, and in the direction of rotation. Chain 3 while sequentially engaging
is sent, and the movable roof 1 moves accordingly.

The movable roof 1 directed by such an arch beam 2 moves in the vertical direction and has a steep slope, so there is always a force trying to fall downward, and it is necessary to brake this. Driving by a hydraulic motor 7 is preferable. Of course, the motor is not limited to a hydraulic motor, and may be an ordinary three-phase induction transmission machine, but in these cases, a separate brake is required. The hydraulic motor 7 is therefore advantageous since it has its own braking force in the opposite direction.

Furthermore, the hydraulic motor has an extremely large rotational torque, is lightweight, compact, and can rotate at low speeds, making it advantageous from the viewpoint of the structure and weight of the reducer.

Dome roofs required for baseball stadiums and the like may consist of large frame arch beams, and in such cases it is practical to stack movable roofs in several stages to increase the open area ratio. If one considers the case where the two layers are stacked one on top of the other, an embodiment as shown in FIG. 2 can be obtained. In other words, the situation can be seen in the second
Shown in the figure. In the figure, the lower movable roof 1a has a sprocket 6 driven by a hydraulic motor 7 as described above.
The moving roof 1a is moved by engaging a chain 3 placed directly in front of the moving roof 1a. Separately, one end of the wire rope 10 is fixed to the base end of the arch beam 2, and the wire rope 10 is moved from this fixed point. is guided to the tip of the movable roof 1a, and at this tip, it is turned back onto the movable roof 1a by the sheave 11, and the other end of the folded back is guided to the top of the movable roof 1a.
It is locked at the bottom of b.

When the lower movable roof 1a is driven upward with the rotation of the sprocket 6, the turning point of the wire rope 10 is pushed by the sheave 11 at the tip of the lower movable roof 1a, and the upper movable roof 1b is also pushed upward in conjunction. That is, the lower movable roof 1a acts to push the upper movable roof 1b upward via the wire rope 10. The state of the movement is shown in FIGS. 3(a) and 3(b). As can be seen from the figure, the wire rope 10 is connected to the arch beam 2.
When the upper part is fully extended linearly, the upper moving roof 1b
has moved completely above the arch beam 2. In this way, the openings of the dome roof, etc. are closed by the moving roofs 1a, lb. Conversely, when opening the movable roofs la and lb, if the direction in which the sprocket 6 is rotated is reversed, the lower movable roof 1 can be opened.
As the wire rope a gradually descends downward, the length of the folded portion of the wire rope 10 becomes longer, so that the upper movable roof 1b descends to overlap with the lower movable roof 1a.

(Effects) As explained in detail above, the retractable roof moving device of the present invention has a chain attached to the underside of the movable roof that can be moved up and down, rotates a gear that engages with this chain, and opens and closes in accordance with the direction of rotation. Since the direction is controlled and driven, when the movable roof is opened, the gravity of the movable roof itself is not applied.
Also, when the moving roof is raised, the rising reaction force is stopped, and these reaction forces are always applied toward the base end of the beam that supports the moving roof through the support shaft of the gear that engages with the chain. Therefore, it is sufficient to provide reinforcement strength sufficient to withstand the linear load acting toward the base end of the arch beam. Therefore, it is not necessary to take into consideration the effect of loads that change the directionality of each other due to bending of the wire lines that occurs when the wires are hung and driven by a winch as in the conventional case.

In addition, in the case of a retractable roof in which multiple movable roofs are stacked one on top of the other and can be moved up and down, a rope 1 belt, etc., with one end fixed to the base end of a beam, is folded back and reversed at the tip of the lower movable roof. Since the end portion thereof is locked to the proximal end portion of the upper movable roof, the upper movable roof can be opened and closed by simply moving the lower movable roof. In this case as well, the force acting on the upper movable roof during opening and closing only pushes the upper movable roof upward from the base end, so that the structural reinforcement strength is quite light.
