Description

  The present invention relates to a three-dimensional parking apparatus such as a mechanical parking apparatus, in which a vehicle entering and exiting the parking apparatus is placed to change the direction of the vehicle, or an article such as an exhibit, furniture, or luggage is placed on the top board. The present invention relates to a turntable device that can be placed and turned.

  In general, a turntable device for an automobile has a recess (pit) formed on a floor surface, and a driving mechanism for horizontally rotating a top plate on which the automobile is placed and a support for supporting the top plate and the like in the recess. And a mechanism is provided, and the top plate is arranged flush with the recess. Since the turntable device places a heavy automobile and changes the direction, the allowable load of the drive mechanism and the support mechanism is increased to correspond to the load of the automobile. For this reason, the turntable apparatus has a problem that the entire apparatus is enlarged and the depth of the recess (pit) for storing the entire apparatus is increased.

  As a device in which such a problem is solved and the pit depth is reduced (the height of the top plate is lowered), a turntable device described in Patent Document 1 is known. The turntable device described in Patent Document 1 distributes the load of an automobile by providing a large number of ball bearings that support the top plate and a large number of base frames that respectively support the ball bearings. The base frame is composed of five circumferential frames made of concentric circles and 32 radial frames radially arranged from a circular plate arranged at the center. The ball bearings are installed at 144 locations where the circumferential frame and the radial frame are orthogonal to each other.

Japanese Patent Laid-Open No. 2008-213658 (FIGS. 1, 2, and 6)

  However, although the turntable device described in Patent Document 1 can be thinned by installing the top plate outside the outer peripheral portion of the drive device, 144 metal ball bearings are installed. The number of circumferential frames and radial frames holding the ball bearings increases, and there is a problem that the number of parts, the number of assembling steps, the assembling work time, and the weight of the entire apparatus increase.

  In other words, in the turntable device in which the support portion is composed of a ball bearing, the sphere is in point contact with the lower surface of the top plate, so that the sphere is easily deformed by wear or load and flattened. When the sphere is flattened, the sphere does not rotate. This increases wear and causes failure. For this reason, in such a turntable device, it is indispensable to increase the number of ball bearings installed and to reduce the load of the automobile applied to each ball bearing.

  In addition, the turntable device described in Patent Document 1 increases the number of parts, the number of assembling steps, and the weight, and it takes time to transport the parts to the work site and assembly time when assembling the parts. It was the cause.

  In the turntable device, ball bearings are respectively installed at positions where five circumferential frames made of concentric circles and 32 radial frames installed on a radial center line intersect. Therefore, the installation interval of the ball bearings installed on the circumferential frame located near the circular plate in the center is smaller than the installation interval of the ball bearings installed on the outermost circumferential frame. It is installed and is arranged unevenly as a whole, and the shared load applied to the ball bearing is also uneven.

The ball bearings arranged in this way are the amount that the ball bearings installed on the outermost circumferential frame are wider than the installation interval of the ball bearings installed on the circumferential frame near the circular plate, Since a large load is applied, it is easy to wear.
Furthermore, since the ball bearing of the turntable device is rotatably installed in the upper opening of the cylindrical wall portion mounted on the flat plate, dust or the like is formed in the gap between the opening and the ball bearing. There is a problem that wear easily increases due to dust, and abnormal noise easily occurs.

  Accordingly, the present invention has been made to solve the above-described problems, and an object thereof is to provide a turntable device in which the height of the entire device is low and the installation cost is reduced.

A turntable device according to the present invention includes a circular top plate that rotates by placing an article, a drive device that rotates the top plate, a guide roller unit that rotatably supports the top plate, A plurality of outer guides arranged at predetermined intervals on an outer circle along an outer peripheral edge of the top plate.

Since the inner guide roller unit and the outer guide roller unit arranged in this way are supported by lines in comparison with the bearings supported by the turntable device described in Patent Document 1, the load applied to each roller. Can be reduced. As a result, the turntable device can be reduced in size by reducing the overall height of the device (the pit depth is shallow), improving the transportability of each member, and reducing the installation cost.
Further, according to this configuration, the drive device includes the driven roller that moves the outer rail in the same rotation as the drive roller, so that the outer rail is rotated by the two rollers of the drive roller and the driven roller. For this reason, it is possible to reduce the size of the roller by reducing the load of each load.

  The number of the inner guide roller units is preferably ½ of the number of the outer guide roller units.

  According to this configuration, since the number of the inner guide roller units is ½ of the number of the outer guide roller units, the load of articles such as a vehicle and the load of the top plate on each roller unit are equally shared. Can be supported. That is, one inner guide roller unit is arranged on the center line between the two outer guide roller units with respect to the two outer guide roller units. Are equally distributed and averaged, so that the load imposed on each roller unit can be reduced, and the entire apparatus can be reduced in size and weight.

  The guide roller unit preferably includes a resin roller.

  According to such a configuration, the turntable device includes a resin roller in the guide roller unit, thereby reducing weight and reducing operation noise compared to metal rollers and metal bearings. Can be achieved. Since the turntable device can reduce the weight by reducing the size of the guide roller unit, it can facilitate the work of transporting the parts that make up the guide roller unit. The working efficiency can be improved.

≪Action≫
Next, the operation of the turntable device 1 will be described.
For example, when turning the direction of the vehicle by the turntable device 1 in FIG. 1, first, the vehicle is self-propelled and placed on the top plate 2. The four tires of the vehicle are placed on the outer divided plate 22 of the top plate 2. That is, the four tires are arranged on two outer guide roller units 41 and 41 arranged next to each other on the outer circle R1 shown in FIG. 3 and on the center line between the two outer guide roller units 41 and 41. It is arranged between one inner guide roller unit 42 and supported at three points.
In addition, the four tires are arranged on the outer circle R1 with the two outer guide roller units 41 and 41 arranged adjacent to each other, and the center line of the two outer guide roller units 41 and 41 sandwiching the inner circle. It is arranged between two inner guide roller units 42, 42 adjacent to each other on R2, and is supported at four points.

  Then, when the user operates the switch on the operation panel (not shown) to drive the drive device 3, for example, the control device (not shown) rotates the top plate 2 90 degrees that is a predetermined angle set in advance. Move to stop. In this way, the user can change the direction of the vehicle to be taken in and out of the multi-story parking device by operating the switch on the operation panel to drive the drive device 3.

  In this case, as shown in FIG. 6, in the driving device 3, the orthogonal shaft motor M1 is rotationally driven by turning on the switch, and the rotation of the orthogonal shaft motor M1 is a gear reduction mechanism including a hypoid gear (not shown) in the gear head M2. The drive roller 32 and the drive sprocket 33 are decelerated and rotated by (not shown). The rotation of the drive sprocket 33 is transmitted to the driven roller 38 via the chain 34, the driven sprocket 39, and the support shaft 37.

The driving roller 32 and the driven roller 38 of the driving device 3 rotate around the outer frame fulcrum shaft 81 in the direction of the outer rail 24 (arrow a direction), with the driving outer frame 36 biased by the spring 88 of the pressing device 8. It is always pressed against the driving surface 24a of the outer rail 24. Further, since the outer rings 32 b and 38 b of the driving roller 32 and the driven roller 38 are made of rubber having high frictional resistance, the driving roller 32 and the driven roller 38 can also reliably transmit the rotational power to the outer rail 24. In addition, the driving sound and vibration during operation can be absorbed and silenced.
For this reason, the outer rail 24 is rotated by applying a rotational force to two places by the two rotating bodies of the driving roller 32 and the driven roller 38.

  As shown in FIGS. 2 and 3, the top plate 2 rotates around the central axis 5 integrally with the outer rail 24. The top plate 2 loaded with the vehicle load has a central shaft 5 fixed at the center supported by a single central bearing 7 so as to be rotatable, and an inner rail 25 fixed on an inner circle R2 has nine inner rails. The outer rail 24 that is rotatably supported by the guide roller unit 42 and fixed on the outer circle R1 is distributed and supported by the 18 outer guide roller units 41 that are twice the inner guide roller unit 42. Is done.

That is, the lower surface 2b of the top plate 2 is supported at 27 locations, and the load of the top plate 2 and the load of the vehicle are distributed and supported substantially uniformly by the guide roller unit 4 and the like.
Further, since the guide roller unit 4 is in line contact with the outer rail 24 and the inner rail 25, the supporting load is not concentrated on one point like the ball bearing supported at the point described in Patent Document 1. Compared to a conventional apparatus using 144 ball bearings, the number of parts, the number of assembling steps, and the cost can be greatly reduced.

For this reason, 27 guide roller units 4 (outer guide roller unit 41 and inner guide roller unit 42) supporting the top plate 2 are distributedly supported to reduce the size of each roller and the entire apparatus. Further, the weight can be reduced.
As a result, as shown in FIG. 2, the pit depth H1 (the height of the turntable body) from the installation surface Ba to the floor surface A of the recess B is set to 90 mm, which is larger than the pit depth of a general turntable device. , It can be shallowed to about 1/2.

  As shown in FIGS. 5 and 7, the driving device 3 disposed in the driving device housing recess C is provided with a motor unit M, a driving inner frame 35 and a driving outer frame 36, and a driving roller 32 and a driven roller. 38, the drive sprocket 33, the driven sprocket 39 and the chain 34 are arranged horizontally, so that the pit depth H2 from the inner bottom of the drive device housing recess C to the floor surface A shown in FIG. ) Is 240 mm, and the depth can be reduced to about ½ of the pit depth of the general drive device housing recess C.

  Therefore, the turntable device 1 of the present invention has the pit depth H1 of the recess B (the height of the turntable body) and the pit depth H2 of the drive device housing recess C (the height of the drive device). By reducing the overall height of the device by making it shallower, the size of each material in the height direction can be shortened to reduce the weight and cost of the entire turntable device 1.

  Further, as shown in FIGS. 5 and 7, all the rollers including the guide roller unit 4, the driving roller 32, and the driven roller 38 disposed on the lower side of the top plate 2 are made of resin (for example, nylon). Thus, it is possible to reduce the size, reduce the driving sound, and reduce the noise. For this reason, since the drive sound of the turntable device 1 is low, the drive sound does not resonate greatly at night or the like.

  As shown in FIG. 2, the outer rail 24 and the inner rail 25 are made thicker because the rolling guide roller unit 4, the driving roller 32, and the driven roller 38 are made of resin, so that the pressing force is reduced. It is possible to reduce the weight and reduce the weight. Further, since the outer rail 24 and the inner rail 25 do not damage the plating of the rolling surfaces, rust does not occur, and therefore, the maintenance cost can be reduced by reducing oil supply and maintenance inspection.

  Thus, the turntable device 1 can improve the transportability and the assembling property when assembling the turntable device 1 in the field by reducing the weight of the entire device. Further, the turntable device 1 can reduce excavation work and reduce costs as the pit depths H1 and H2 of the recess B and the drive device storage recess C become shallow. Further, when the work period from the production of the pit to the installation of the turntable is opened, it is necessary to take measures to ensure the safety of the pits. However, since the pit depths H1 and H2 are shallow, safety measures can be easily taken.
