【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0014] Figure 2 shows a vehicle transport device and a vehicle support section that constitute a parking device equipped with the present invention. FIG.

[0015] The vehicle transport device 1 runs on rails 5 arranged horizontally on a travel path 2. A plurality of vehicle support sections 3 are arranged in parallel on both sides or one side of the travel path 2. ing. This vehicle support section 3 is used for carrying vehicles placed on the vehicle transport device 1. This is a parking room for storing.

[0016] In FIG. 2, 7 is a truck frame of the vehicle transfer device 1, and the vehicle Two conveyors 10a and 10b for transversely conveying the material are arranged in parallel. The conveyor A 10a and 10b are roller conveyors, of which 10a is a front wheel conveyor. , 10b is a rear wheel conveyor. The longitudinal direction of the vehicle is aligned with the bogie frame 7. It is placed on the conveyor so that it matches the longitudinal direction (the running direction of the vehicle conveyance device), Due to the simultaneous rotation of both conveyors in the same direction, the rotation is perpendicular to the running direction of the vehicle conveyance device. is transferred in the lateral direction.

[0017] In the figure, reference numeral 11 is connected to both conveyors via chains, and conveyors 10a, This is a conveyor drive device that rotates the conveyor belt 10b. In the drawing, front wheel conveyor 1 The rear wheel conveyor 10b is configured to be wider than the rear wheel conveyor 10a, but this is due to the This is to allow vehicles of various sizes with different lengths to be placed thereon. 13 is Wheels 15 for driving the truck frame 7 along the rails 5 drive the wheels 13. It is a traveling drive device that

[0018] Each vehicle support section 3 includes a front wheel conveyor provided in the vehicle conveyance device 1. The front wheel conveyor 16a and the rear wheel conveyor 10a correspond to the rear wheel conveyor 10a and the rear wheel conveyor 10b. A conveyor 16b is provided in parallel, and the vehicle conveyance device 1 is connected to the vehicle support area. When it stops at the side of the picture 3, each conveyor is connected.

[0019] Conveyors 10a and 10b of the vehicle conveyance device 1 and the vehicle support section 3 After the conveyors 16a and 16b are connected, each conveyor rotates in the same direction, and the vehicle transport Vehicles are transferred between the device 1 and the vehicle support section 3.

[0020] Each of the vehicle support compartments 3 has conveyors 16a, 16b in the vehicle support compartment that are rotatably driven. No conveyor drive is provided to move each conveyor in the vehicle support section 3. 16a and 16b utilize the driving force of a drive device provided in the vehicle conveyance device 1. It is supposed to rotate.

[0021] To explain the mechanism in this respect, first, there is a structure shown in FIG. 3 on the bogie frame 7. The component power transmission device 20 is movable in the lateral direction perpendicular to the traveling direction of the vehicle conveyance device 1. It is set in.

[0022] The power transmission device 20 has a total length similar to that of the conveyors 10a and 10b of the vehicle conveyance device 1. The frame 21 is based on a frame 21 having a short length, and the frame 21 is connected to the bogie frame. It is installed on the bogie frame 7 so as to be perpendicular to the longitudinal direction of the bogie frame 7. It is supported so that it can move in the intersecting directions. The frame 21 has one end connected to the truck. The other end of the power cylinder 22 fixed to the frame 7 is connected, and the operation of the power cylinder is It is said that it is possible to move in the lateral direction perpendicular to the traveling direction of the vehicle transport device by It is something.

[0023] Furthermore, rollers 23, 23 are pivotally supported at both ends of the frame 21. Applicable The roller 23 is rotatably mounted on the shaft 24 with the shaft 24 parallel to the traveling direction of the vehicle conveyance device 1. It is supported. Each roller 23 is provided with a chain as a transmission means. Motors 26 as drive devices 26 are connected via 25, respectively. -26 allows each roller 23 to rotate in forward and reverse directions. Each roller 23 transmits the rotational driving force of the drive device 26 to the conveyors 16a, 16b of the vehicle support section 3. This is a friction wheel 23 for power transmission.

[0024] On the other hand, each of the vehicle support sections 3 is provided so as to face the power transmission friction wheel 23. A roller 30 is attached to each. This roller 30 is the power transmission As the device 20 moves laterally, it comes into close contact with the power transmission friction wheel 23, and the friction It is a driven friction wheel to which rotational driving force is transmitted from the wheel 23, and its rotating shaft 31 is connected to the It is provided parallel to the rotating shaft of the power transmission friction wheel 23.

[0025] The driven friction wheel 30 is connected to each of the controllers provided in the vehicle support section 3. It is interlocked with the bears 16a and 16b, and is not affected by contact with the power transmission friction wheel 23. When the dynamic friction wheel 30 is rotated, each conveyor 16a, 16b is also rotated accordingly. It is said to be a mechanism that rotates.

[0026] The power transmission device 20 has a total length (from the rollers at both ends to the rollers). length) is slightly shorter than the length of the conveyors 10a and 10b of the vehicle conveyance device 1. has been done. When the vehicle is transferred, the power cylinder 22 is activated. The frame 21 moves in the direction of the vehicle support section 3, and the power transmission friction wheel 23 moves. It contacts the driven friction wheel 30 provided in the vehicle support section 3 with an appropriate pressure. after that, By the operation of the conveyor drive device 11, the conveyors 10a, 1 of the vehicle conveyance device 1 0b rotates, and the power transmission friction wheel 23 operates its own drive device 26. Therefore, it rotates. The rotational force of the power transmission friction wheel 23 is transmitted to the driven friction wheel 30, As a result, the conveyors 16a and 16b interlocked with the driven friction wheel 30 are moved to convey the vehicle. It rotates in the same direction as the rotation direction of the conveyors 10a and 10b of the apparatus 1.

[0027] Note that in order to change the conveyance direction of the vehicle, the conveyor drive device of the vehicle conveyance device 1 must be changed. The rotation directions of the drive unit 11 and the drive device 26 of the power transmission friction wheel 23 are respectively reversed. All you have to do is turn it around.

[0028] Furthermore, the transmission efficiency of the rotational force is determined between the power transmission friction wheel 23 and the driven friction wheel 30. Since it depends on the magnitude of the contact pressure, the friction for power transmission by the power cylinder 22 By adjusting the pressing force of the wheel 23 in the direction of the driven friction wheel 30, the transmission effect of rotational force can be improved. All you have to do is control the rate.

[0029] In the present invention, in the parking device having the above configuration, the conveyor 10a of the vehicle conveyance device 1 , 10b (hereinafter referred to as "end rollers") 51, 52, 53, and 54 are flipped upward and inward while the conveyance device 1 is running.

[0030] That is, as the mechanism is shown in FIG. 51, 52, 53, and 54 are each non-fixed rollers. Here non-rigid A fixed roller is a roller whose spindle is not supported by a fixed bearing. It means ra.

[0031] Each of the end rollers (in FIG. 1, the end roller 51 is taken as an example) Both ends (in FIG. 1, one end of the support shaft (rotating shaft) 51a) of the ), one end 55a of the first doglegged lever 55 is rotatably attached to each The bent portion 55b of the lever 55 is connected to the roller 5 adjacent to the end roller. It is rotatably attached to a fixed support shaft 56a of No. 6.

[0032] The other end 55c of the lever 55 is provided with a connecting rod that can reciprocate in the horizontal direction. One end 57a of the connecting rod 57 is rotatably attached to the other end 57 of the connecting rod 57. One end 58a of a second doglegged lever 58 is rotatably connected to b. moreover, The other end portion 58b of the second dogleg-shaped lever 58 is connected to the central portion 60 via the connecting member 59. b is rotatably connected to one end 60a of a lever 60 rotatably supported by a shaft 61. Ru. Due to the action of the second dogleg-shaped lever 58, the connecting rod 57 is moved approximately horizontally. Both ends 60 of the lever 60 have a rotatable support shaft 61 in the center. It is converted into an up and down movement of a and 60c.

[0033] A profiling roller 62 is rotatably supported on the other end 60c of the lever 60. The profiling roller 62 contacts the cam 63 attached to the power transmission device 20. ing. Since the cam 63 is attached to the power transmission device 20, the cam 63 is attached to the power transmission device 20. The station 20 moves laterally toward the traveling direction of the vehicle conveyance device 1 as described above. It moves with the movement.

[0034] The end rollers 51 are arranged to move the vehicle between the vehicle transport device 1 and the vehicle support section 3. The first dog-shaped lever 55 is used to move the It's being jumped up. The raised end roller 51 is free from its own weight or spring. It is constantly trying to move downward due to the urging force of Since the action of is converted into an upward action of the profiling roller 62, the corresponding profiling roller 62 The roller 62 is constantly trying to move upward. However, the corresponding profiling roller 62 contacts the lower surface of the cam 63 attached to the power transmission device 20 and prevents its upward movement. Since the end roller 51 is restrained, the end roller 51 that is interlocked with the end roller 51 is in an upturned state. The situation is maintained.

[0035] When the vehicle is transferred, the power transmission device 20 is connected to the vehicle support area. It moves to supply rotational force to the conveyors 16a and 16b in picture 3, but at this time The cam 63 also moves together. The profiling roller is moved by the movement of the cam 63. 62 is released from the restriction of the cam 63, the front Since the inhibition of the downward movement of the end roller 51 is released, the end roller 5 1 moves downward. Then, the end roller 51 is connected to the first dogleg-shaped lever 55. By hitting a stopper (not shown), the conveyor rollers will be on the same level as other conveyor rollers. is set to

[0036] When the transfer of the vehicle is completed and the power transmission device 20 returns to its original position on the bogie frame 7, the The profiling roller 63 pushes down the profiling roller 62 and restricts its upward movement. Ru. As a result, the end roller 51 interlocking with the profiling roller 62 springs upward. It will be in a raised state.

[0037] With the above configuration and mechanism, each end roller 51, 52, 53, 54 can move the vehicle. While the power transmission device 20 is not moving laterally to transmit, it always jumps upward in an arc. It's being lifted up. As a result, the width of W in FIG. 1 (conveyor rollers 10a, 10 There are flip-up rollers at both ends of b, so the total width is 2W). The overall width becomes shorter. Therefore, the vehicle transport device 1 may come into contact with other components while traveling. There is less risk of damage.

[0038] In the illustrated embodiment, the first dogleg roller 55 is an end roller. 51 is disclosed. However, the first doglegged roller 55 is not adjacent to the end roller 51 but is located at a separate position. on the spindle of the conveyor roller (for example, conveyor roller 65 in Figure 3). It is also possible to attach it, and in this case, the width of the W mentioned above should be made larger. becomes possible.

[0039] By the way, in the parking device having the above configuration, the conveyor in each vehicle support section 3 has its own drive. Since it is not connected to a moving device, it rotates freely. Therefore, if the vehicle is parked The vehicle rotates due to vibrations, etc., and the vehicle placed on it moves and falls. Such risks are expected. Therefore, in order to prevent such dangers, the following vehicles are An anti-movement device is provided.

[0040] First, the rotating shaft 31 of the driven friction wheel 30 has a latch as shown in FIGS. A jet wheel 32 is mounted and fixed so as to rotate integrally with the rotating shaft 31, A stopper pawl 33 is engaged with the ratchet wheel 32 from below.

[0041] In the illustrated embodiment, the stopper pawl 33 is an engaging pawl centered around the support shaft 34. The portion 35 is formed to be small and lightweight, and the head portion 36 is formed to be large and heavy. . Therefore, the engaging pawl 35 is always in the engaged state with the ratchet wheel 32 due to gravity. The ratchet wheel 32 rotates clockwise in FIG. This prevents it from rotating. In addition, using a spring, the engaging claw 35 portion can be pressed. The ratchet wheel 32 is biased in the direction of the ratchet wheel 32 or the like. It may also be possible to maintain the engaged state with. In FIG. 5, 37 is a driven friction wheel 30 39 is a bearing that supports the rotating shaft 31 of the conveyor 16a of the vehicle support section 3. , 16b, and the like.

[0042] In the embodiment described above, the stopper pawl 33 is engaged from below the ratchet wheel 32. A mechanism is provided to prevent the ratchet wheel 32 from rotating clockwise in FIG. Therefore, a gear 38 is provided between the driven friction wheel 30 and the conveyors 16a, 16b. , 38 (see FIG. 3), the rotational direction of the driven friction wheel 30 and the conveyor 16a are , 16b are arranged to rotate in opposite directions. For this reason, the The driven friction wheel 30 in FIG. 4 is prevented from rotating clockwise by the jet mechanism. As a result, the conveyors 16a, 16b of the vehicle support section 3 are equipped with friction wheels for power transmission. Rotation in 23 directions is prevented.

[0043] On the other hand, the stopper claw 3 is attached to the end of the frame 21 of the power transmission device 20. Press the head 36 part of No. 3 to engage the engaging pawl 35 and the ratchet wheel 32. A pusher 41 for releasing is attached.

[0044] The pusher 41 is integrated with the power transmission friction wheel 23 in the direction of the driven friction wheel 30. When the power transmission friction wheel 23 comes into contact with the driven friction wheel 30, the stopper claw 33 The engagement is released by pressing the head 36 portion of the holder. Conversely, when moving a vehicle When the transmission is completed, the power transmission friction wheel 23 and the driven friction wheel are moved by the movement of the power transmission device 20. When the contact with 30 is released, the weight of the head 36 portion and the engaging claw 35 portion is reduced as described above. Due to the difference or biasing force of the spring, the stopper pawl 33 is moved against the ratchet wheel 32. It is something that re-engages with.

[0045] Furthermore, a tire stopper (not shown) is provided on the back side of the vehicle support section 3. to prevent parked vehicles from moving away from the travel path 2. It has stopped.

[0046] As mentioned above, the ratchet mechanism provided on the driven friction wheel 30 and the vehicle support section 3 The tire stopper installed on the back side prevents the parked vehicle from moving. Risks such as the vehicle falling can be avoided.

[0047] In the above embodiment, as shown in the above-mentioned Japanese Utility Model Publication No. 1-150764, The vehicle is placed on the transport device in the direction in which the running direction of the vehicle transport device and the longitudinal direction of the vehicle match. Although the present invention has been explained by taking as an example a parking device of the type installed in a parking lot, the invention is not limited to this. The vehicle should be positioned so that the running direction of the vehicle transport device and the longitudinal direction of the vehicle are perpendicular to each other. Of course, a parking device in which the parking device is placed on a conveyor device may also be used.

[0048]

[Effect of the idea]

According to the present invention, while the vehicle conveyance device is running, the conveyor of the conveyance device supports the vehicle. The risk of coming into contact with the conveyor etc. in the compartment is extremely reduced.

[0049] Moreover, the vertical movement of the conveyor roller is linked to the movement of the power transmission friction wheel. Because of this, accidents involving contact between conveyors can be easily and reliably prevented.
