The mechanical parking device 1 is provided with an entry / exit room 2 for entering / exiting a vehicle. A plurality of parking rooms 3 are arranged in a row in the longitudinal direction inside the parking device 1, and a traveling path 4 is provided along the parking rooms 3. A traveling rail 5 is laid on the traveling path 4, and a traveling carriage 6 on which a vehicle is mounted can freely travel on the traveling rail 5. In the traveling carriage 6 and the parking room 3, the vehicle 8 is arranged in a direction orthogonal to the traveling path 4, that is, the vehicle is arranged in the traveling carriage 6
To the parking room 3 or the vehicle 8 from the parking room 3 to the traveling carriage 6 are provided with transverse feed conveyors 9 and 10 (hereinafter, also simply referred to as conveyors) that can be connected to each other.

In the parking device 1, in order to increase the number of cars that can be accommodated, it is possible to stack the parking rooms 3 to form a plurality of parking floors. In this case, the traveling rail 5 is laid on the lowermost floor, and the traveling carriage 6 is provided with a lift mechanism for exchanging the vehicle between the parking room located above and the traveling carriage. A traveling carriage having this lift mechanism is called a traveling carriage with a lift. In addition, a traveling rail 5 may be provided for each parking floor, and a traveling carriage having no lift mechanism may be provided for each floor.

FIG. 6 shows a traveling carriage 6 with a lift. The traveling carriage 6 with a lift has wheels 6a, and the wheels 6a

When the vehicle is to be unloaded, the conveyors 9 and 10 are driven in the opposite direction to the loading, so that the vehicle can be unloaded in the same manner as the loading.

[0008]

However, the mechanical parking device having the above structure has the following problems. The structure including the parking room 3, the traveling path 4, and the traveling rail 5 of the mechanical parking device 1 is divided into several parts in order to satisfy all of the transportability, the assembling property, and the assembly accuracy of the parts. And unitize and produce each unit at the factory. And transport it to the installation site in units,
A method of performing final assembly at the installation location of the mechanical parking device 1 is adopted. The present inventors have already disclosed in detail Japanese Patent Application No. 6-192169, Japanese Patent Application No. 6-210429, etc. regarding the unitization of constituent parts. Similarly, the traveling vehicle 6 is also divided into several units for factory production, and these units are carried into the structure for final assembly.

Therefore, it is inevitable that a slight assembly error will occur in the structure and the traveling carriage when the final assembly is carried out at the installation site. Since the rails 5 are fixed in a predetermined positional relationship based on the same assembly reference position, the influence of the assembly error is small and the respective parts do not interfere with each other. However, the traveling carriage 6 with a lift moves inside the structure, and the reference position at the time of assembly is different from that of the structure having the parking room 3, the traveling path 4, and the traveling carriage 5. Moreover, parking room 3
When the vehicle is installed in multiple stages, the traveling carriage 6 also needs to have a height corresponding to the height, so that the assembly error between the structure and the traveling carriage 6 may become a value that cannot be ignored as the height increases. is there. Then, it becomes impossible to provide an appropriate space between the parking room 3 and the traveling carriage 6, which hinders the traveling of the traveling carriage 6. Therefore, it is necessary to set a large interval between the parking room 3 and the traveling carriage 6 in advance. However, in this case, the interval between the conveyors 9 and 10 also becomes large, and smoothness in delivery of the vehicle between the parking room 3 and the traveling carriage 6 is lacking, which is not a preferable countermeasure. It was

Further, as the traveling distance of the traveling carriage increases,
The urethane rubber arranged on the outer peripheral portion of the wheel 6a is worn and the diameter of the wheel 6a is reduced. Then, the conveyor 9 of the traveling carriage 6
Then, the height of the conveyor 10 in the parking room 3 was deviated, which also caused a lack of smooth delivery of the vehicle.

The present invention has been made in view of the above problems, and an object thereof is to easily correct an assembly error between a parking room and a traveling carriage and a change in a positional relationship due to wear. It is in.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, the same or corresponding parts as those of the conventional example are denoted by the same reference numerals, and detailed description is omitted.

FIG. 1 shows a front view of a traveling carriage 6 with a lift according to an embodiment of the present invention, and FIG. 2 shows a side view of the traveling carriage 6 with a lift. The parking room 3 shown in FIG. 1 shows an example in which it is stacked in three stages.
Has an ascending / descending height corresponding to these three-tiered parking rooms. The elevating body frame 13 of the traveling carriage with lift 6 includes four columns 12 erected on the main frame 11, a reinforcing member 19,
It is formed by connecting and reinforcing with 20. A chain 21 is hung around the elevating table 7 that is guided up and down by the elevating body frame 13 to transmit the power of the elevating motor 22. Further, the traveling carriage 6 with a lift has wheels 6a.
Is driven by the traveling motor 23 (Fig. 2),
It is possible to move freely on the traveling rail 5.

By the way, an H-shaped steel is used for the traveling rail 5, and angle steel or the like is fixed along the web side surface of the traveling rail 5 to form the guide rail 24. A main guide roller 25 is provided on the main frame 11 of the traveling carriage 6 with lift so as to be guided by the guide rail 24 below the rotation axis of the wheels 6a (FIG. 2). Since the main guide rollers 25 are guided by the guide rails 24, the traveling carriage 6 with lift can travel along the traveling path 4 without departing from the traveling rails 5.

Further, the traveling carriage 6 with a lift is provided with an auxiliary guide roller 26. By the way, in the multi-tiered parking room 3, as shown in FIG. 1, a main frame 30 parallel to the traveling path 4 is mounted on a base 29 unitized by a vertical column 28 provided under each horizontal frame 27. Then, the conveyor 10 is formed on the main frame 30 in the direction orthogonal to the traveling path 4. The main frames 30 of the parking rooms 3 adjacent to each other in the front and rear are continuous along the traveling path 4. The sub guide roller 26 uses the web side surface of the main frame 30 as a guide rail structure. The reinforcing members 19 and 20 forming the elevating body frame 13 of the traveling carriage 6 with a lift are provided at substantially the same height as the main frame 30 of the parking room 3, and a sub guide roller is provided at a substantially central portion of the reinforcing member 20 in the front-rear direction. 26 is attached (Fig. 2).

When the traveling carriage 6 with a lift moves along the traveling path 4, it is basically guided by the main guide roller 25. Therefore, the distance between the guide rail 24 fixed to the web side surface of the traveling rail 5 and the main guide roller 25 is set to be the minimum required distance for the traveling carriage 6 with lift to travel. The sub-guide roller 26 is provided in the main frame 30 of the parking room 3 mainly when the upper part of the elevator frame 13 is bent during traveling of the traveling carriage 6 with a lift.
When the auxiliary guide roller 26 is guided to the side surface of the web of the main frame 30, the traveling carriage 6 with lift is kept traveling stably. Therefore, the distance between the main frame 30 and the sub guide roller 26 is set to a distance that does not normally make contact.

Next, the adjusting means for supporting the inclination of the traveling carriage frame relative to the wheel shaft 31 of the traveling carriage 6 will be described. The traveling carriage frame is
1 shows a skeleton portion of a traveling carriage formed by a main frame 11, columns 12, reinforcing members 19, 20 and the like.

As shown in FIG. 1, the left and right wheels 6a are supported on both ends of a wheel shaft 31. Further, the wheel shaft 31 is fixed to the traveling carriage frame (specifically, the support plate 3 fixed to a portion where the main frame 11 and the column 12 shown in FIG. 2 intersect.
2, 33), fixed via an adjusting bearing 34. This adjusting bearing 34 is shown in FIGS. 3 and 4. The adjustment bearing 34 includes a radial bearing 35 and a flange plate 36, and a bolt 37 and a nut 38 are used to support the support plate 32,
Holds 33. The flange plate 36 has a wheel shaft 31 and bolts.
A flat plate portion 361 having a circular hole penetrating therethrough and a flange portion 362 having a surface orthogonal to the flat plate portion 361 are formed. Further, as shown in FIG. 4, the support plates 32 and 33 are provided with an oval shaft hole 39 and a bolt hole 40 which are long in the vertical direction and through which the wheel shaft 31 and the bolt 37 penetrate. Further, the support plates 32, 33 are formed with protrusions 32a, 33a, and the head of the adjusting bolt 41 screwed to the protrusions 32a, 33a.
The 411 is brought into contact with the flange portion 362 of the flange plate 36. In addition, as shown in FIG. 1, the adjustment bearing 34 is used only for one of the two left and right bearings that pivotally support the wheel shaft 31,
The other is a normal radial bearing 42 without adjustment means.
It is supported by.

When the inclination of the traveling carriage frame with respect to the wheel shaft 31 is changed by using the adjusting means having the above construction, the following procedure is performed. First, the bolt 37 and the nut 38 are loosened to release the fixing of the adjustment bearing 34 to the support plates 32 and 33. Next, the adjustment bolt 41 is rotated. Then, the heads of the adjusting bolts 41 with respect to the protruding pieces 32a, 33a.
The protrusions 32a and 33a are guided by the spiral groove of the adjusting bolt 41 by the action of the forward and backward movement of 411 and move up and down with respect to the flange portion 362. Then, the support plates 32, 33 to which the protruding pieces 32a, 33a are fixed are moved up and down. The movable range at this time is from the upper end of the shaft hole 39 to the lower end of the wheel shaft 31. As mentioned above, the other radial bearing that supports the wheel shaft 31.
42 (see FIG. 1) has no adjusting means, so the adjusting bearing 34
By appropriately moving up and down the support plates 32, 33 on the side having the angle, the angle formed by the traveling carriage frame with the wheel shaft 31 can be changed with the radial bearing 42 as the center of rotation.
Then, when the desired tilt angle is obtained, the bolt is again
Tighten 37 and nut 38, adjust bearing 34 to support plate 32,
Fix at 33.

The operation and effect obtained from the embodiment of the present invention having the above configuration are as follows. By supporting the traveling carriage frame so that the inclination of the traveling carriage frame can be changed with respect to the wheel shaft 31 of the traveling carriage 6, the assembly error between the traveling carriage 6 and the structure having the parking room 3, the traveling path 4, and the traveling rail 5 is large. (For example, the structure is assembled without distortion, and the traveling carriage frame is deformed into a parallelogram when viewed from the direction shown in FIG. 1)
However, by tilting the traveling carriage frame according to the assembled state of the structure, the parking room 3 and the traveling carriage 6
It becomes possible to provide an appropriate space between the and. That is, it is possible to easily correct an assembly error between the traveling carriage 6 and the structure having different assembly reference positions. Therefore, there is no possibility that the auxiliary guide roller 26 of the traveling carriage 6 will come into contact with the main frame 30 of the parking room 3 with an excessive force.

By the way, it is also possible to attach adjustment bearings 34 for supporting the inclination of the traveling carriage frame with respect to the wheel shaft 31 to both the left and right sides of the wheel shaft 31. In this case, the inclination angle of the traveling carriage frame is adjusted by fixing one of the left and right adjusting bearings 34 and moving only the other adjusting bearing 34.

The advantages of using the adjustment bearings 34 on both the right and left sides are as follows. FIG.
As shown in FIG. 5, the wheels 6a of the traveling carriage 6 with a lift are provided with urethane rubber on their outer peripheral portions 6b to reduce traveling vibration. Therefore, if the traveling distance of the traveling carriage increases,
The wheel outer peripheral portion 6b is worn and the diameter of the wheel 6a is reduced. Then, the traveling carriage frame sinks into the parking room 3 by the reduced diameter of the wheels 6a, and the heights of the conveyor 9 of the traveling carriage 6 and the conveyor 10 of the parking room 3 are displaced,
The delivery of vehicles between each other will lack smoothness.
At this time, by adjusting the left and right adjustment bearings 34 in the direction in which the traveling bogie frame is raised with respect to the wheel shaft 31, it is possible to correct the diameter reduction due to wear of the wheel outer peripheral portion 6b.

In the case of the traveling carriage 6 with a lift, the lifting platform 7
Although it is possible to correct the diameter reduction due to the wear of the wheel outer peripheral portion 6b by controlling the stop height of the vehicle, a type in which a traveling carriage without a lift is used (a traveling carriage is arranged for each parking floor) Type) mechanical parking equipment,
In the past, it was particularly effective because there was no way other than replacing the wheels.

[0026]

According to the present invention, the following effects are obtained. Supporting the inclination of the traveling carriage frame with respect to the rotation axis of the wheel is changeable, the parking room,
With respect to the structure having the traveling path and the traveling rail, the inclination of the traveling carriage frame assembled on the basis of the separate assembly reference position can be matched with the inclination of the structure. Therefore, it is possible to easily correct an assembly error between the structural body and the traveling carriage and deterioration of the positional relationship due to wear, and adjust to an optimum state. Therefore, it becomes possible to drive the traveling carriage safely and reliably, and the gap between the parking room and the traveling carriage can be set optimally. It will be possible to deliver smoothly.
