DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device used for lifting various objects to be raised and lowered, and more particularly to a lifting device applied to parking equipment.

[0002]

2. Description of the Related Art Conventionally, as a technique belonging to such a field, a technique disclosed in Japanese Patent Application Laid-Open No. 11-229655 is known. The conventional parking facility described in this publication is configured as a multi-story parking lot having a parking berth and a parking floor provided on different floors. This parking facility is provided with a lift device (elevator) for transferring vehicles between the entrance / exit berth and the parking floor. The lift device is provided with a conveyor that can transfer the vehicle in the lateral direction (the width direction of the vehicle).

[0003] The parking floor is provided with a plurality of parking sections (parking rooms) for storing vehicles, and a transport cart for transporting the vehicles between the lift device and each parking section. That is, the parking floor is provided with two parallel parking section rows each having a plurality of parking sections arranged side by side in the vertical direction (the front-rear direction of the vehicle). The transport vehicle can travel freely between these two parking section rows. In addition, each parking stall and the transport trolley have 2
Row conveyors (conveyors for front wheels and rear wheels) are provided, and are provided on these when transferring vehicles between the lift device and the transport vehicle, and between the transport vehicle and each parking section. Operate the conveyor appropriately.

[0004] Here, the conveyor of the lift device provided in the parking facility described in the publication is composed of two rows of first spiral conveyors capable of transferring a vehicle in two directions, that is, a horizontal direction and a vertical direction. A first roller conveyor disposed between the spiral conveyors and capable of transporting the vehicle in the vertical direction.
In addition, beside the stop position of the lift device in the entrance / exit berth, two rows of first horizontal transfer conveyors that can be connected to the spiral conveyor of the lift device are arranged. Further, the loading / unloading berth includes two rows of second spiral conveyors that can be connected to the first horizontal transport conveyor and a second roller conveyor that is disposed between the spiral conveyors and that can transport the vehicle in the vertical direction. Are located. In addition, two rows of second horizontal transfer conveyors that can be connected to each of the second spiral conveyors are arranged at the entrance / exit berth.

The second spiral conveyor and the second roller conveyor form an annular transfer path. Therefore, the direction of the vehicle on each conveyor can be changed by appropriately setting the operation direction (transfer direction of the vehicle) of each conveyor. Thus, for example, it is possible to change the direction so that the vehicle conveyed from the parking floor to the entrance / exit berth by the lift device can exit the vehicle by traveling forward.

[0006]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No.
According to the parking facility described in Japanese Patent No. 229655, it is possible to always allow the vehicle to enter the parking facility forward and to leave the vehicle from the parking facility facility always forward. Ease and safety can be improved. However, the entrance / exit berth of the parking facility has an extremely complicated structure in which a spiral conveyor, a roller conveyor, and a lateral transfer conveyor are combined. Furthermore, in order to change the direction of the vehicle smoothly and reliably, it is necessary to control each of these conveyors extremely complicatedly and accurately. For this reason, the conventional parking facility has a problem that the manufacturing cost, the maintenance cost, and the like are rather increased.

[0007] On the other hand, from the viewpoint of simultaneously improving the ease of entry and exit of the parking facility and the safety, and simplifying the structure of the entrance / exit berth, it is conceivable to use a lift-type turntable. Can be In this case, although the lift for raising and lowering the turntable (pallet) may be relatively small, the height of the pit, that is, the height at which the installation location is dug is made as small as possible in view of the construction cost of the parking facilities. Should. Therefore, it is required that the total height of the lifting device is also made as small as possible. However, in general, when the total height of a hydraulic actuator that can be applied as a lifting device is set to be small, the driving force per unit decreases. The problem exists.

Accordingly, an object of the present invention is to provide an elevating device which can easily suppress the overall height and can surely elevate the elevating object.

[0009]

According to a first aspect of the present invention, there is provided an elevating device for vertically moving a table member with respect to a base member to elevate an object mounted on the table member. A driven body fixed to the table member or the base member and having a first inclined portion forming a predetermined angle with respect to a horizontal plane; and a second driven member parallel to the first inclined portion.
A movable body having an inclined portion, the second inclined portion being moved forward and backward in a state of facing the first inclined portion, the first inclined portion of the driven body and the second inclined portion of the movable body, A lift mechanism including a driving force transmitting member rotatable with respect to the first inclined portion and the second inclined portion is provided.

In the lifting device having such a configuration, for example, the driven body is fixed to (the back surface of) the table member,
The moving body is arranged on a base member and is movable forward and backward by moving means such as a fluid pressure cylinder and an electric motor.
Further, the first inclined portion of the driven body and the second inclined portion of the moving body are
They are opposed (parallel) via a driving force transmission member. The driving force transmission member is in contact with the first inclined portion and the second inclined portion, and is rotatable with respect to the first inclined portion and the second inclined portion.

Thus, when the moving body is moved forward, that is, moved to the driven body side, the driving force transmitting member in contact with the second inclined portion of the moving body rotates in one direction with respect to the second inclined portion. Move. Here, the second inclined portion is parallel to the first inclined portion. Therefore, when the driving force transmitting member rolls in one direction with respect to the second inclined portion, the driven body including the first inclined portion in contact with the driving force transmitting member is moved relative to the moving body including the second inclined portion. Relative movement in the one direction. As a result, the table member to which the follower is fixed is at a maximum from the base member,
The height is raised by a head equivalent to twice the smaller of the height of the first inclined portion and the height of the second inclined portion.

On the other hand, if the moving body is retracted, that is, moved to the opposite side of the driven body, the driving force transmitting member in contact with the second inclined portion of the moving body moves the one of the driving force with respect to the second inclined portion. Rolls in the opposite direction (other direction). Here, the second inclined portion is parallel to the first inclined portion. Therefore, when the driving force transmitting member rolls in the other direction with respect to the second inclined portion, the driven body including the first inclined portion in contact with the driving force transmitting member becomes the second inclined portion.
It moves relative to the moving body including the inclined portion in the other direction. As a result, the raised table member can be lowered with respect to the base member.

As described above, according to the elevating device, by moving the moving body forward and backward, the table member can be reliably moved up and down with respect to the base member, and the overall height of the elevating device can be reduced. Becomes possible. Further, the table member is mechanically supported on the base member via a driven body, a driving force transmission member, and a moving body. Therefore, it is possible to reliably maintain the state where the table member is raised. In addition, the follower is (the upper surface of) the base member.
And the movable body can be moved forward and backward with respect to the table member in a state where the second inclined portion is opposed to the first inclined portion of the driven member in parallel via the driving force transmitting member. Is obtained. It is also possible to attach a caster or the like to the base member to make the lifting device movable.

In this case, it is preferable that the apparatus further comprises a guide means for vertically guiding the table member which moves up and down with respect to the base member, and the moving body is moved forward and backward in the horizontal direction.

Thus, if the moving body is moved forward and backward in the horizontal direction, the driven body is surely moved in the vertical direction, so that the table member can be moved up and down straight with respect to the base member. Become.

Further, the first inclined portion of the driven member and the second inclined portion of the moving member are provided.
Racks having the same pitch are arranged on the inclined portion, respectively, and the driving force transmitting member preferably has a pinion gear that meshes with each rack.

By adopting such a configuration, if the moving body is moved forward and backward, the driven body will surely move relative to the moving body via the driving force transmitting member. Therefore,
It is possible to realize a lifting device that operates reliably and can raise and lower the lifting target efficiently.

Further, it is preferable that a pair of lift mechanisms is provided, and that each moving body of the lift mechanism is moved forward and backward in directions opposite to each other.

In this case, for example, the driven members may be fixed in opposite directions to each other at both ends of the table member, and the moving members may be arranged so that the second inclined portion faces the first inclined portion of the driven member. In addition, it becomes possible to depress the vicinity of the center of the table member.

Further, it is preferable that a plurality of lift mechanisms are provided, and that the moving bodies of each lift mechanism are connected in a row and are respectively moved forward and backward in the same direction.

By adopting such a configuration, it is possible to drive the moving bodies connected in one row by one moving means (fluid pressure cylinder, electric motor, etc.).

This lifting device is preferably applied to parking equipment. In this case, it is preferable that a turntable provided in the parking equipment be an object to be raised and lowered.

Can be rotated about the rotation axis 27 of the conveyor pulley 23.

The conveyors 5f and 5r and the conveyors 11f and 11r adjacent to each other by the gap closing device 30A.
In order to close the gap D, the hydraulic cylinder 55 as a drive unit is operated to extend the stroke of the piston rod. As a result, the bell crank 50 is
As shown in (2), it rotates in a predetermined direction (counterclockwise in the case of the left bell crank in the figure). With the rotation of the bell crank 50, the closing member 31A attached to the first arm portion 51 of the bell crank 50 moves upward from below the conveyors 5f, 5r, 11f, 11r along the outer periphery of the conveyor pulley 23. And inserted into the gap D.

On the other hand, for example, the front wheel conveyors 5f and 11f adjacent to each other and the rear wheel conveyor 5r
When the vehicle C is transferred between the two, the hydraulic cylinder 55 is operated to reduce the stroke of the piston rod. This causes the bell crank 50 to rotate in the opposite direction (clockwise in the case of the left bell crank 50 in the figure) as shown in FIG. With the rotation of the bell crank 50, the closing member 31A attached to the first arm portion 51 of the bell crank 50 moves below the gap D between the conveyors 5f and 5r and the conveyors 11f and 11r, or each of the conveyors 5f and 5f. It is moved to below 5r, 11f, 11r. Even if such a configuration is adopted,
Conveyors 5f, 5r, 11f, 11 are provided by gap closing device 30A (blocking member 31A, closing member drive mechanism 40A).
r does not hinder the transfer of vehicle C,
And the conveyors 5f, 5r and the conveyor 11 which are adjacent to each other.
The gap D between f and 11r can be reliably closed.

Here, when the closing member 31A is inserted from below by rotating the bell crank 50 with respect to the gap D as in the gap closing device 30A, the width of the closing member 31A is set to the width of the adjacent conveyor 5f. , 5r and conveyor 1
It is necessary to set the gap D to be smaller than the shortest distance ds between the gaps 1f and 11r. For this reason, there is a possibility that the gap D cannot be sufficiently closed by one closing member 31A.
Based on this point, when equipping the parking facility with the gap closing device 30A, as shown in FIG.
It is preferable to dispose one 0A for each of the adjacent ends of the conveyors 5f, 5r, 11f, 11r. This makes it possible to sufficiently close the gap D near the upper surface of the conveyor belt 24 even if the narrow closing member 31A is used.

In this case, the bell crank 50 provided for one of the conveyors 5f and 5r is rotated, and the bell crank 50 provided for the other conveyors 11f and 11r is rotated first. It is rotated with the operation start timing appropriately delayed from that of the bell crank 50. Thus, after the closing member 31A attached to one bell crank 50 is inserted from below into the gap D, the closing member 31A attached to the other bell crank 50 is inserted from below. Will be. In addition,
It is also possible to form the closing member 31A with a rectangular cross section, a circular cross section, or the like. Further, it is preferable to form the back surface of the closing member 31A along the shape of the end of the conveyor 5f, 5r, 11f, 11r like the right side of the closing member 31A shown in FIG.
