CONSTITUTION: In order to transfer a car between a traveling truck and a parking roan of a mechanical parking system, a conveyor is installed there. A power transmitting roller 19 of the traveling truck 6 is attached, under pressure, to a driven roller 22 in linkage with a conveyor of the parking room 8, driving the conveyor of the parking roan 8 with power of the traveling truck 6. This power transmitting roller 19 is supported by a movable frame 18. In addition, a main frame 17 of the traveling truck 6 is provided with each hook 35 for delivery of a car in linkage with the movable frame 18. The parking roan 8 is provided with an engaging part 38 with the hook 35. Interlocking with a fact that the power transmitting roller 19 is pressed to the driven roller 22 under pressure, the hook 35 is drawn out, making it be connected to the engaging part 38 of the parking room 8. Since the traveling truck 6 and the parking room 8 are connected together with the hook 35, pressing-contact force of the power transmitting roller 19 to the driven roller 22 is increased, so that power transmission is carried out positively, through which car delivery is performed with certainty.

Further, when a traveling carriage with a lift having an elevating device is used as the traveling carriage 6, if the traveling carriage is installed only in the lowermost stage, one vehicle can handle a plurality of stages. The present inventors have already disclosed the details of the mechanical parking device configured as described above in Japanese Patent Application No. 6-53249. Regarding the traveling carriage with lift, the present inventors have already disclosed the details in Japanese Patent Application No. 6-56619.

By the way, the conveyor 15 of the traveling carriage 6 described above.
And the conveyor 16 in the parking room 8 rotate in synchronization with each other. This synchronous rotation will be described with reference to FIG.

[0010]

However, the mechanical parking device configured as described above has the following problems. Originally, it is desirable that the traveling vehicle 6 is designed not to be a rigid body for downsizing and weight saving, but to be designed so as to allow the main frame 17 and the like to bend and deform to the extent that it does not hinder safety. However, the power transmission roller 19
When the main frame 17 is deflected by the reaction force of pressing against the driven roller 22 of the parking room 8, there is a risk that sufficient pressing force cannot be obtained and power cannot be sufficiently transmitted.

Further, in the case of a traveling vehicle with a lift, since it has a structure extending upward, there is a risk that the amount of deflection of the entire traveling vehicle will increase and the power transmission will become insufficient, especially when the vehicle is transferred in the upper stage. there were.

In order to prevent this, it is possible to reinforce the traveling carriage 6 sufficiently, but this causes an increase in the weight of the traveling carriage, and accordingly, it is necessary to reinforce the entire parking device. . Particularly when the number of units (2, 3, etc.) to be installed is large, the overall size and weight of the device are considerably increased, and this is not preferable because it may affect the building 1 etc.

The present invention has been made in view of the above problems, and an object of the present invention is to allow the pressure contact force from the power transmission roller to the driven roller while allowing the deflection that occurs due to the weight reduction of the traveling carriage. It is to provide a connecting structure for a traveling carriage and a parking room to secure and transmit power more reliably.

A hydraulic circuit diagram of the above is shown in FIG. As is clear from the fact that the relief valve 49 is provided between the hydraulic cylinder 21, the hydraulic switching valve 48, and the hydraulic pump 50, the power transmission roller 19 described later is provided.
When the contact pressure between the driven roller 22 and the driven roller 22 reaches the set value, the pressure is automatically maintained. Power transmission rollers 19 are provided at both ends of the movable frame 18. Further, a center sprocket 29 fixed to an output shaft 28 driven by a drive motor 20 (FIG. 2), an end sprocket 30 fixed to a power transmission roller 19, and a chain 31.
The power is transmitted to the power transmission roller 19 by this.

At the end of the movable frame 18, there are provided an open bar 32 and an arm 33 protruding laterally of the power transmission roller 19 (FIG. 2). The open bar 32 moves the movable frame 18 in a direction orthogonal to the traveling path 4 (FIG. 11),
The stopper claw 42 of the driven roller 22, which will be described later, is opened. The arm 33 is a hook that is rotatably attached to the main frame 17 when the movable frame 18 moves.
It comes in contact with 35. The hook 35 is installed near the end of the movable frame 18, and is normally stored so that the tip end thereof is located above the rotation shaft 37 by the urging of the butterfly spring 36. However, by pushing with the arm 33 attached to the open rod 32, it is possible to incline toward the parking room 8 and to make the tip end project.

On the side of the parking shelf 9 forming the parking room 8,
A driven roller 22 with which the power transmission roller 19 abuts, and a connecting rod 38 that is an engaging portion with the hook 35 are provided. Although the right end of FIG. 1 is not shown in detail, it has a structure symmetrical to the left end.

Now, the structure of the peripheral portion of the driven roller 22 will be described with reference to FIG. The driven roller 22 has a rotating shaft 39 at its shaft center, and the rotating shaft 39 is supported by a bracket 40 fixed to the parking rack 9. Further, the rotating shaft 39 is connected to the transmission member 25 (see FIG. 11) that drives the conveyor 16 in the parking room 8. Furthermore, the ratchet wheel 41 is attached to the rotary shaft 39.
And the bracket 40 is provided with stopper claws 42 that engage with the ratchet wheel 41. Stopper claw 42
Is engaged with the ratchet wheel 41, the inadvertent rotation of the conveyor 16 in the parking room 8 in the vehicle mounted state is prevented.

Further, when the power transmission roller 19 of the traveling carriage 6 contacts the driven roller 22, the release rod 32 is moved to the stopper claw 42.
The stopper claw 42 in FIG.
The stopper claw 42 can be released from the ratchet wheel 41 by moving to the state shown by the dotted line. Therefore,
At this time, the driven roller 22 freely rotates.

Next, the procedure for connecting the hook 35 and the connecting rod 38, which is the main part of the present invention, will be described with reference to FIGS.
Will be described by showing only the relevant portion. FIG. 5A shows a state where the movable frame 18 of the traveling carriage 6 is not moving with respect to the main frame (neutral state). This is the case when the traveling vehicle is running. This time, the hook
The butterfly spring 36 is retracted by the urging force of the butterfly spring 36 so that its tip is located above the rotation shaft 37. The arm 33 provided on the movable frame 18 is in contact with the middle portion of the hook 35.

Next, FIG. 5B shows a state in which the traveling vehicle reaches the target parking room 8 and the movable frame 18 is moved toward the parking room 8. The arm 33 presses the intermediate portion of the hook 35 as the movable frame 18 moves in the parking room direction. Therefore, the hook 35 opposes the urging force of the butterfly spring 36 and tilts in the direction of the parking room 8 about the pivot shaft 37.

Further, FIG. 5C shows a state in which the movable frame 18 is further moved toward the parking room 8 and the power transmission roller 19 is in contact with the driven roller 22 of the parking room 8. Figure 5 above
From the state of (b) to this state, the arm 33 further presses the intermediate portion of the hook 35, and the hook 35 further increases the tilt angle. When the power transmission roller 19 comes into contact with the driven roller 22 of the parking room 8, the hook 35 moves to the parking rack 9.
Engages with the connecting rod 38 provided on the side of the. Therefore, the traveling carriage 6 and the parking rack 9 in the parking room 8 are connected.

After the hook 35 is engaged with the connecting rod 38, the movable frame 18 may be brought closer to the parking room 8 in order to increase the pressure contact force between the power transmission roller 19 and the driven roller 22. Therefore, when the hook 35 engages with the arm 33, the rear surface 351 of the hook 35 becomes substantially horizontal, and
33 is the height h from the rotary shaft 37 to the attachment position of the hook 35 so that the rear surface 351 of the hook 35 can slide.
And the width t from the rotary shaft 37 to the back surface 351 of the hook 35 are set to be substantially the same. Therefore, the hook 35 becomes the arm 33.
Does not interfere with the progress of.

Next, a procedure for detaching the hook 35 engaged with the connecting rod 38 will be described. When the vehicle 10 is transferred between the traveling carriage 6 and the parking room 8, as shown in FIG.
Although 35 is engaged with the connecting rod 38, when transfer of the vehicle 10 is completed and the traveling carriage 6 moves to the traveling path 4 again, the movable frame 18 moves as shown in FIG. 5 (b). It moves backward toward the center of the traveling carriage 6. Then, the arm 33 also retracts together with the movable frame 18, and the pressing force on the hook 35 decreases, so that the hook 35 is urged by the butterfly spring 36 to erect the tip end thereof about the rotation shaft 37, and the hook 35 moves. It separates from the connecting rod 38. Then, as shown in FIG. 5A, when the movable frame 18 returns to the neutral position, the hook 35 is retracted by the urging of the butterfly spring 36 so that the tip of the hook 35 is positioned above the rotation shaft 37. It

The operational effects obtained from the present invention having the above-mentioned structure are as follows. The hook 35 is stored in the traveling carriage 6 by the urging of the butterfly spring 36 when the movable frame 18 is in the neutral state. However, when the movable frame 18 of the traveling carriage 6 is moved toward the parking room 8 and the power transmission roller 19 provided at the side end of the movable frame 18 is pressed against the driven roller 22 of the parking room 8, the movable frame 18 is moved. In conjunction with
The hook 35 provided on the traveling carriage 6 can be projected to connect the hook 35 to the connecting rod 38 provided on the parking shelf 9 of the parking room 8. That is, the power transmission roller 19 and the driven roller 22
The hook 35 is engaged with the connecting rod 38 in the vicinity of the pressure contact portion with
Since the traveling carriage and the parking room are connected to each other, in order to reliably transmit power, the power transmission roller with respect to the driven roller 22 is
When the pressure contact force of 19 is increased, the flexure of the traveling carriage 6 that is about to be generated by the reaction force can be efficiently stopped by utilizing the strength of the parking rack 9. Therefore, as the pressure contact force is increased, the power transmission roller 19 and the driven roller 22 are more closely contacted with each other, and the power transmission can be performed more reliably. Since the present invention prevents bending by connecting with other strength members only when a force is applied to the traveling carriage 6, it is not necessary to reinforce the traveling carriage 6 itself to prevent the deflection, and the size of the apparatus can be reduced. And weight reduction can be promoted.

Next, a second embodiment of the present invention will be described with reference to FIG. Descriptions of parts or portions corresponding to those of the first embodiment in the second embodiment will be omitted.

In the present embodiment, the present invention is applied to a traveling carriage 43 with a lift as shown in FIG. Here, the traveling carriage with lift 43 will be briefly described. The traveling vehicle with lift 43 is designed to deliver the vehicle 10 to each stage of a multi-stage parking room 8 (FIG. 11) provided on both sides of one traveling path 4 by one traveling vehicle. At this time, the traveling carriage with lift 43
Is installed in the lowermost stage of the parking room 8, and an elevating device (lifter) corresponding to the number of installed stages of the parking room is used in the parking room 8 above it. Therefore, the conveyor 15, the movable frame 18 (having the power transmission roller 19 at the end), the hook 35, and the like are attached to the lifting table 44. A traveling carriage 43 with a lift shown in FIG. 6 corresponds to a three-tiered parking room, and a support column 45 for guiding the lifting platform 44 upward and a lifting motor 4 are provided.
6. Equipped with a lifting chain 47 etc.

When the vehicle 10 is delivered to the upper parking room, as shown in FIG. 6, it is lifted to the height of the target parking room.
Raise 44. Since the pillar 45 that guides the lifting platform 44 has a structure in which the root portion is supported by the main frame 17, the amount of deflection above the pillar 45 is increased by the reaction force that brings the power transmission roller 19 into contact with the driven roller 22 in the parking room. It tends to be large, and there is a possibility that power transmission will be further insufficient as compared with the traveling carriage 6 (single-stage type) described in the first embodiment. Therefore, by engaging the hook 35 provided on the lift table with the connecting rod 38 provided in the parking chamber 8, it is possible to suppress the occurrence of the above-mentioned deflection and obtain the same effect as that of the first embodiment. In particular, reinforcing the traveling carriage with lift 43 itself to prevent it from bending causes a considerable increase in size and weight, so the effect of reducing the size and weight of the present embodiment is very large. .

By the way, since the amount of deflection of the column 45 increases as it goes upward, the connecting rod 38 that engages with the hook 35.
It is advantageous in terms of cost to install at least in the uppermost stage of the parking room 8 and to provide the stages below it according to the situation.

[0033]

As described above, the present invention has the following effects. In a movable parking frame provided on a traveling carriage, a mechanical parking device provided with a power transmission roller that presses a driven roller interlocking with a conveyor in a parking room to transmit driving force on the traveling carriage side, wherein the traveling carriage is By installing a hook that goes in and out in conjunction with the movable frame, and by forming an engaging portion with the hook in the parking room,
When the power transmission roller is brought into pressure contact with the driven roller in the parking room, the hook provided on the traveling carriage is projected in conjunction with the movable frame and engaged with the connecting rod that is an engaging portion with the hook. You can At this time, the hook is engaged with the connecting rod in the vicinity of the pressure contact portion between the power transmission roller and the driven roller to connect the traveling carriage and the parking chamber. When the pressure contact force of the power transmission roller with respect to is increased, the bending of the traveling carriage that is about to occur due to the reaction force can be efficiently stopped by utilizing the strength of the parking rack. Therefore, by increasing the pressure contact force, the power transmission roller and the driven roller can be more sufficiently brought into close contact with each other, and power can be transmitted more reliably.

As described above, according to the present invention, since the traveling carriage is prevented from being bent by connecting with other strength members (parking shelves) only when the traveling carriage is under a force, the traveling carriage itself is reinforced. Since it is not necessary to apply it, it is possible to reduce the size and weight of the traveling carriage. Therefore, it is possible to promote downsizing and weight reduction of the entire parking device, and this effect becomes greater particularly when a traveling carriage with a lift is used or when the number of units constituting the mechanical parking device is large.
