Description

  TECHNICAL FIELD The present invention relates to a turntable installed in an up-and-down space of a parking tower, and when the turntable is rotated, the turntable passing through a gap on the turnrail is quiet and travels smoothly without vibration. It is.

  In the conventional turntable device, a gap is required for the lifting lift to move up and down in the lifting space, so the turn rail also has a gap. For turning the turntable, a drive wheel and a plurality of support wheels are provided on the lower surface of the turntable. The driving wheels are arranged on the same side one by one before and after the turntable so that the driving force can be transmitted even when positioned in the gap. Therefore, when one driving wheel is in the gap, the other driving wheel Because it is on the turn rail, it can rotate. The support wheel is a rotatable wheel that is mounted at a position wider than the width of the gap and can withstand the load when the vehicle is mounted.

The lift can pass the vehicle by passing the turntable. For this purpose, the turn rail is provided with a gap through which the lift can be lowered so that it can be lowered below the turntable. When the turntable changes direction, the lift lift is lowered from the gap between the turnrails, and then the drive wheels rotate and the support wheels follow to turn on the turnrail, thereby changing the direction of the vehicle.

Since the conventional turn rail has a gap through which the lift lift moves up and down, both the rail sides of the gap are set in a horizontal state when the drive wheel and the support wheel pass.
However, there is a problem that the drive wheel and the support wheel are deformed horizontally by bending due to the vehicle weight mounted on the turntable, so that contact sound and vibration increase and smooth rotation cannot be achieved.

The present invention forms the presence or absence of a gap, so that even when the turntable is deflected due to the vehicle weight, the drive wheel and the support wheel are smoothly passed by using an integrated rail that closes the gap when passing through the gap. Like that.
When the lift lifts up and down, it is operated to create a gap. The operation is a configuration in which the turn rail is rotated in the ascending / descending space so that the ascending / descending lift can be moved up and down and formed in a state having a gap.

  The present invention provides a turn rail 6 capable of quietly operating the turntable 5 installed in the boarding place S of the parking tower 1. The turn rail 6 operates so that the gap is opened when the lifting lift 2 moves up and down so that the driving wheel 14 and the support wheel 15 can easily pass when the turntable 5 changes direction. The turn rail is formed by closing the gap by turning.

  FIG. 1 shows a parking tower 1 erected on a high floor, and the center is provided in the vertical direction as an elevating space E in which an elevating lift 2 moves up and down. In the elevating space E, parking rooms X and Y are provided on a plurality of floors in adjacent left and right directions. In the parking rooms X and Y, a traverse tray 3 that reciprocates between the elevating space E and the parking rooms X and Y is arranged. A traverse roller 12 is provided as a drive unit at the front and rear ends of the elevating space E and the parking chambers X and Y to support the traverse tray 3 and to move laterally.

  A plurality of transverse rollers 12 are driven to rotate by projecting a plurality of them horizontally. The traverse tray 3 includes a traverse rail having a U-shaped cross section supported at the front and rear ends by the traverse roller 12, and traverses as the traverse roller 12 rotates.

  The parking tower 1 includes a boarding place S where the vehicle C can enter and exit at a position on the ground surface GL. In the boarding place S, the lift 2 and the floor surface intersect and are integrated to form a horizontal and flat passage, which enables the vehicle C to run and people to pass. The lifting / lowering lift 2 suspends the suspended portion 10 from the lifting / lowering drive unit via the cord 9 and engages the guide rail 4.

The traversing roller 12 is positioned on the left and right side surfaces with respect to the direction in which the vehicle C enters, and moves up and down horizontally in a pair of left and right, and includes a lift hawk. The lift hawk protrudes inward from the fixing member 12 in a comb shape. The floor has a tray hawk fixed from the inside to the outside so as to block the space between the lift hawks, and when the lift 2 is raised and lowered so that it can pass, the lift hawk and the tray Hawks are integrated to form a flat passage with few gaps.

  The parking chambers X and Y include a traverse roller 12 that traverses the traverse tray 3 in the horizontal direction. The traverse roller 12 has a plurality of traverse rollers 12 mounted in the horizontal direction at either one of the parking chambers X and Y and the front and rear ends of the elevating space E, and the traverse tray mounted on the traverse roller 12. 3 is reciprocated in the elevating space E from either one of the parking rooms X and Y. The vehicle C is placed with a tire supported on a tray fork fixed to the transverse tray 3.

The transverse tray 3 is connected to a central portion of the transverse rail by arranging a frame in the front-rear direction.
On the frame, the tray hawk is fixed in a comb shape from the inside to the outside. When the lift 2 is located at the boarding place S, the turntable 5 includes a tray hawk that is integrated with the lift 2 and overlaps a gap between the lift hawks and forms a passage for the vehicle C and a person. The surface on which the vehicle C enters the boarding place S is on the ground surface GL and is connected to the road.

The lifting / lowering lift 2 is suspended from the lifting / lowering drive unit 9 and rolled by a guide roller pivotally attached to the hanging portion 10 of the lifting / lowering lift 2 guided by guide rails 4 erected at the four corners of the lifting / lowering space E. Go up and down. Fixing members 12 are fixed to the four suspension portions 10 at both ends in parallel with the vehicle C entering direction. The fixing member 11 is fixed in a comb shape so that the lift hawk can mount the tire of the vehicle C, and is lifted up and down to a pair of left and right so that the vehicle C can be conveyed. The suspended portion 10 is suspended from the upper portion by the cord-like body 9 and moves up and down along the guide rail 4.

The guide rails 4 are erected from the pit P to the uppermost floor and are arranged at the four corners of the elevating space E to guide the elevating lift 2 up and down. The pit P is a space in which the lift 2 can stand by in the lower stage of the turn rail 6 and can incorporate a motor 21 to be rotated. The turntable 5 of the boarding place S is at the same height as the ground surface GL, and the floor surface 23 is lowered by the thickness of the turntable 5 so that the level of the turnrail 6 is increased.

  The turn rail 6 is provided with a fixed rail 7 fixed to the floor surface 23 and a rotating rail 8 that rotates and is connected to the fixed rail 7 to close or open the gap 26. The rail frame 22 that supports the rotating rail 8 is fixed to the front and rear ends of the elevating space E, supports the rotating rail 8 so as to be rotatable, and can mount the turntable 5 and the vehicle C. The turntable 5 and the rotating rail 8 are provided with a bearing at the center of the rail frame 22 and rotate around the bearing. The turntable 5 has a drive wheel 14 on the lower surface and can rotate 180 degrees. The rotating rail 8 is provided with a driving portion in the bearing and rotates several tens of degrees to the left and right in order to contact the fixed rail 7.

  FIG. 2 shows that the turntable 5 rotates counterclockwise along the turn rail 6 on the drawing, and the rotating rail 8 of the turn rail 6 also rotates counterclockwise to eliminate the gap 26. One drive wheel 14 of the turntable 5 is provided at each of the front and rear ends, and the direction is changed by the drive rotation of the motor 17. The shaft core 13 that supports the turntable 5 is rotatably mounted and receives a load by the support wheel 15 to maintain a horizontal state.

The rotating rail 8 rotates to the left in the rotation direction and is connected to the fixed rail 7 to close the upper left and lower right gaps 26 in the drawing to form an integral rail surface. When the turntable 5 is mounted on the rotating rail 8 and connected to the fixed rail 7 and starts to rotate and moves on the fixed rail 7, the rotating rail 8 rotates to the right, The turn rail 6 is formed by closing the lower left gap 26. The turntable 5 rotates about 90 degrees in the first half and rotates about 90 degrees in the second half around the shaft core 13, and is parallel to the lift 2.

The rotation rail 8 has a shaft gear 19 fixed to the rail shaft 18 so that it can rotate about the rail shaft 18, a pinion 20 is meshed with the shaft gear 19, and the pinion 20 is rotated by a motor 21. .

FIG. 4 shows a fitting portion 24 where the fixed rail 7 and the rotating rail 8 are connected, and the connecting surface 25 has no step or gap. When the fixed rail 7 and the rotating rail 8 are brought into contact with each other, the fitting portion 24 has a stepped surface and an uneven shape to engage with each other, thereby eliminating a step and a gap to increase rigidity.
The drive wheel 14 and the support wheel 15 travel with a load applied to the turn rail 6, and can smoothly roll the fitting portion 24.

  FIG. 5 shows that the contact surface of the drive wheel 14 and the support wheel 15 is inclined so that the fitting portion 24 can move more smoothly when the drive wheel 14 and the support wheel 15 roll. When passing, since the driving wheel 14 and the support wheel 15 partially pass through the connecting surface 25, vibration noise can be suppressed low.

(Description of parking tower operation)
The entering vehicle C enters the boarding place S and stops where the lift 2 and the turntable 5 form an integral passage. In the warehousing command, when the parking room X / Y (described on the upper floor) is designated on the operation panel (not shown), the lift 2 is lifted, the vehicle C is mounted, and the upper floor is elevated from the designated floor. When the traversing tray 3 traverses the lower stage of the lifting lift 2 from the parking chambers X and Y, the lifting lift 2 descends and delivers the vehicle C to the traversing tray 3. The traversing tray 3 carries the vehicle C, returns to the parking rooms X and Y, and completes the warehousing.

  When leaving the vehicle, the vehicle C to be delivered is commanded using the operation panel. The traversing tray 3 traverses into the elevating space E from the designated parking rooms X and Y. The lifting lift 2 ascends and passes the traverse tray 3 to scoop up and receive the vehicle C. The traversing tray 3 becomes an empty car and returns to the parking rooms X and Y to open the elevating space E. The lift 2 is lowered to the boarding place S with the vehicle C mounted in the lift space E. The vehicle C passes through the turntable 5 at the boarding point S and descends to the pit P, and delivers the vehicle C to the turntable 5.

  When the turntable 5 receives the vehicle C, the turntable 5 rotates to turn the rotating rail 8 and closes the gap 26. The rotating rail 8 rotates with the turntable 5 mounted, and is connected to the fixed rail 7 to overlap the fitting portion 24 to form the turn rail 6. Turning direction of the turntable 5 is such that the vehicle C can be driven to the exit by rotating 180 degrees. When passing the first gap 26, the turntable 5 rotates 90 degrees, and the remaining 90 degrees rotates. Therefore, the rotating rail 8 is rotated in the opposite direction, the next gap 26 is closed, and the connecting surface 25 is formed and rotated.

  The turntable 5 stops on the rotating rail 8. The rotating rail 8 starts rotating and rotates to a position where the gap 26 is opened in a state where the turntable 5 is mounted. In the turntable 5 whose direction has been changed, the lifting lift 2 is lifted from below to be united to form a horizontal passage. Vehicle C drives and completes loading / unloading from boarding point S.

  When the boarding place S is used as a barrier wheel, an elevating mechanism is added to the rotating rail 8 and moved up and down when the turntable 5 is mounted on the rotating rail 8. In the state of getting in the boarding place S, the rotating rail 8 is lowered to make the upper surface of the turntable 5 flush with the floor surface 23. Then, the turntable 5 can be integrated with the lifting lift 2 to form a horizontal boarding floor without unevenness. The horizontal boarding floor has the effect of allowing easy walking and wheelchair traffic.

When turning the vehicle C, the turn rail 8 can be lifted to be flush with the fixed rail 7 to form the turn rail 6 that allows the turn table 5 to rotate. Then, the rotating rail 8 can be lowered again to make it a flat surface to easily form a barrier wheel.
