Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a two-stage multi-level parking device used for parking a vehicle in two stages.

[0002]

[Prior Art]

 A two-stage multi-story parking system as shown in Fig. 4 has already existed, in which a car or the like can be parked three-dimensionally so that the parking space can be effectively used. And a lifting frame 5 is suspended via a chain 3 interlocked with the expansion and contraction operation of the cylinder device 2 and sprockets 4 for guiding the chain.

When this is used, the vehicle w is parked on the elevating frame 5 by operating the hydraulic cylinder device 2 and lowering the elevating frame 5 to the ground, and then the hydraulic cylinder device 2 is reversely operated to raise and lower the frame 5. Is raised to a certain height, and then the vehicle w is also parked under the lifting frame 5.

[0004]

[Problems to be solved by the device]

 Since the conventional two-stage multi-storey parking device uses the hydraulic cylinder device 2 and the chain 3, it takes time and effort to perform maintenance and inspection of each of these parts and the hydraulic pressure generators related to these parts. There is also a danger that the lifting frame 5 will be dropped all at once due to damage to the hydraulic system or disconnection of the chain 3. It is an object of the present invention to provide a novel two-stage multi-level parking device that does not cause such problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides at least a pair of jack devices for transmitting the rotation of a motor to an input shaft on both upper sides of a portal main frame, and each jack device is a worm that is interlocked with the rotation of the input shaft. The output screw shaft is operated up and down via a wheel transmission mechanism. On the other hand, an elevating frame is provided inside the main frame and is vertically movable while being guided by the frame. Each of the opposite sides is characterized in that it is suspended from the lower end of each of the output screw shafts via a link mechanism that is freely movable in the vertical direction. In this case, the motor shall not be automatically braked by the braking device when it stops rotating, and should be manually operable in the event of a power failure.

[0006]

[Action]

 The product of the present invention is not a hydraulic cylinder device or a chain, but a jack or link mechanism consisting of a motor and a worm wheel transmission mechanism, which makes maintenance and inspection relatively easy. Moreover, even if the driving force of the motor disappears, the self-locking action of the worm wheel transmission mechanism keeps the elevating frame at a fixed position via the output screw shaft, preventing sudden drops. Improves safety.

【Example】

 FIG. 1 is a side view of the device of the present invention, FIG. 2 is a vertical cross-sectional front view of the device, and FIG. 3 is a view showing a link mechanism used in the device. In the figure, 1A is a gate-shaped main frame, and a pair of jacks 6, 6 are fixed to the upper part. The jack 6 does not transmit the rotation of the motor 7 to the input shaft (not shown) via the transmission shaft s, and the rotation of the input shaft causes the output screw shaft 8 to be transmitted via the worm wheel transmission mechanisms 6a and 6a. , 8 are operated vertically. It is assumed that the motor 7 is automatically braked by the brake mechanism 7a when the rotation is stopped, and that it can be rotated by hand by using the detachable handle 9 when a power failure occurs. 6b and 6b are protective cylinders for the output screw shafts 8, 8.

Reference numeral 5A denotes an elevating frame positioned inside the main frame 1A, which includes a horizontal floor portion 10 and side wall portions 11 and 11 provided on each side in the width direction. Four guide rollers 12 ... Are provided symmetrically on the outer surface of each of the side wall portions 11 and 11, and these rollers 12 are provided on the standing wall portions 13 of the main frame 1A. It is assumed that the horizontal floor portion 10 of the elevating frame 5A is vertically moved while being fitted in the inner groove 14 ...

However, the respective sides of the lifting frame 5A facing each other in the width direction are adapted to be hung from the lower ends of the output screw shafts 8 and 8 via link mechanisms 15 and 15. Specifically, Do as follows. That is, a link member 15a is attached to the lower ends of the output screw shafts 8 and 8, and a link member 15b having an inverted U-shaped portion k as shown in FIG. 3 is attached to the lower end of the link member 15a. In addition, a link member 15c having an elongated hole h formed in the upper part is provided inside the inverted U-shaped part k, and a pin 16 inserted in the elongated hole h is fixed to the lower part of the inverted U-shaped part k. The lower end of the link member 15c is axially attached to the metal fittings 17 and 17 fixed to each side of the horizontal floor portion 10 of the elevating frame 5A in the width direction, and the link mechanisms 15 and 15 are moved up and down by a dimension related to the length of the slot h. It is supposed to move in the direction. In the figure, GL is the ground, and 18 is a fixing bolt of the main frame 1A.

To explain an example of use of the device of the present invention configured as described above, when the vehicle w is parked on the elevating frame 5A, the motor 7 is rotated so that the output screw shafts 8, 8 of the jacks 6, 6 are rotated. By lowering and displacing, the elevating frame 5A is lowered toward the ground GL. The elevating frame 5A thus lowered is automatically stopped by detecting that the horizontal floor 10 has reached the ground GL by a detection device (not shown). It is unavoidable that the motor 7 will be stopped after the detection signal is output from the detection device, but in this case, the link mechanisms 15 and 15 will float vertically and become horizontal. Even after the floor portion 10 reaches the ground GL, the descending displacement of the output screw shafts 8 and 8 is still allowed, so that an unreasonable compressive load acts on the output screw shafts 8 and 8 and this causes buckling. The situation of being punished is avoided. After this, the automobile w is parked on the elevating frame 5A, and then the motor 7 is reversed to raise and displace the output screw shafts 8 and 8 so that the elevating frame 5A can reach a certain height. Try to raise it. The motor 7 may suddenly stop due to a power failure or the like while the elevating frame 5A is rising. In such a case, the output screw shafts 8 and 8 are operated via the worm wheel transmission mechanisms 6a and 6a. Therefore, the reverse actuating force to the motor 7 side due to the load acting on the output screw shafts 8 and 8 is completely locked by the self-locking operation of the worm wheel transmission mechanisms 6a and 6a, and the output screw shafts 8 and 8 are completely locked. The shafts 8 and 8 are never displaced downward. Further, the brake mechanism 7a of the motor 7 is also automatically operated to prevent the rotation of the input shafts of the jacks 6 and 6, so that the downward displacement of the output screw shafts 8 and 8 is further reliably prevented. .. Therefore, an accident due to a sudden drop of the lifting frame 5A can be surely avoided. After the elevating frame 5A has risen to a certain height, another vehicle w is parked below it.

On the other hand, when the automobile w parked in a two-tiered state is taken out of the apparatus, the above-described parking procedure may be performed in reverse. In this case, it may not be possible to operate the motor 7 due to a power failure, but in such a case, after rotating the brake mechanism 7a of the motor 7 to the non-braking state, the handle 9 is used to rotate the motor 7. Try to rotate the shaft manually.

[0012]

[Effect of the device]

 According to the present invention described above, since the main operating parts are composed of the motor, jack, and link mechanism, maintenance and inspection can be performed more easily than the conventional ones having hydraulic cylinder devices and chains as constituent elements. In addition, even if the motor's operating force disappears due to a power outage, etc., the lifting frame is supported by the output screw shaft and held at a fixed position, so there is no risk of a sudden drop of the lifting frame. In addition to improving safety, it also prevents the output screw shaft from being forced by the free movement of the link mechanism and allows the lifting frame to operate smoothly.
