Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator holding device in an elevator type or elevator slide type parking device (hereinafter referred to as an elevator type parking device or the like).

[0002]

[Prior Art]

 A multi-level parking system that uses an elevator such as an elevator is used to hoist or unwind a wire rope by an elevator driving device and raise or lower the elevator that is connected to the wire rope to move a car into or out of each parking room. It is supposed to do. In such an elevator-type parking system, even if the elevator is stopped at the corresponding position in each parking room, the load on the elevator changes, that is, the car, etc. moves from the elevator to the parking room. As a result, the wire rope contracts (the wire rope expands when a car or the like moves toward the lift), and a step is created between the lift and the parking room level, which prevents the car from moving smoothly. was there.

Therefore, for example, a technique such as Japanese Utility Model Laid-Open No. 50-150085 shown in FIG. 2 has been proposed. In the figure, 1 is a hoistway wall, 2 is a hoisting platform that hoists up and down along the hoistway wall 1 by a wire rope 3, and 4 is an arm driving device including a hydraulic cylinder device fixed to the bottom of the hoisting platform 2, and the like. The arm 5 is extended and retracted toward the hoistway wall 1 while being guided by the arm guide 6, and is driven. A stopper 7 is fixed to the hoistway wall 1, and is provided at a position where it engages with the stopper 7 when the arm 5 is extended.

When raising and lowering the elevator base 2, the arm 5 is always retracted, and when the elevator base 2 is raised and lowered to a position where a parking room is present for loading and unloading an automobile or the like, After temporarily stopping the lift 2 at a position slightly higher than the parking room level, the arm drive device 4 extends the arm 5, and then the arm 5 engages with the stopper 7 to loosen the wire rope 3 somewhat. The elevating table 2 is lowered to a state where the weight of the elevating table 2 is supported by the stopper 7.

If the automobile or the like is moved in such a state, the wire rope 3 does not expand or contract smoothly regardless of whether the vehicle is entering the parking room or the elevator table 2. It is possible to move a car or the like.

In the case of moving the automobile or the like and raising and lowering the elevating table 2, first, the wire rope 3 is wound up to eliminate the looseness of the wire rope 3, and then the arm driving device 4 is operated to retract the arm 5. Then, the elevating table 2 is moved up and down.

[0007]

[Problems to be solved by the device]

 However, in such a conventional device, every time a loading / unloading operation to / from the parking room is performed, an extra operation such as loosening or tensioning the wire rope 3 and engaging the arm 5 with the stopper 7, There was a drawback that extra time such as disengagement was required and the waiting time of the customer was extremely long. Further, the wire rope 3 can be loosened or stretched only by a hoisting drum type elevator drive device that winds the wire rope 3 around a drum, and the elevator 2 and a counter are provided at both ends of the wire rope 3. -It cannot be used for a parking system in which weights are attached and the lift 2 is raised and lowered in a slippery manner.

Since the present invention has been made in view of the above points, it is possible to smoothly move an automobile or the like into and out of any type of elevator-type parking device, etc. It is an object of the present invention to provide a lifting platform holding device that does not require the.

[0009]

[Means for Solving the Problems]

 The present invention is a parking device for moving an elevator, which is suspended by a wire rope, up and down along an upright guide rail to allow a vehicle or the like to enter and leave each parking room. A flexible rod and a clamping device for compressing the guide rail are provided, and a conversion means for converting the sliding motion of the rod into a rotational motion to operate the clamping device is provided.

[0010]

[Action]

 With the above-mentioned structure, the linear sliding motion of the rod is converted into the rotational motion of the clamping device to grab or release the guide rail.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is an overall perspective view of an elevator 20 equipped with the device of the present invention, FIG. 3 is an enlarged plan view of the device of the present invention, FIG. 4 is a view taken along the line XX in FIG. 1, and FIG. FIG. 20 is a view as seen from the direction of the Y-line, in which 20 is an elevating platform that can be moved up and down along the guide rails 21 by the wire rope 3, 22 is a pallet carrier that is horizontally movable on the elevating platform 20, and 23 is an automobile. A pallet which is placed on and is conveyed by the pallet carrier 22,

Reference numeral 30 denotes a driving device such as a power cylinder fixed to the bottom surface of the lifting table 20, which extends or retracts the rod 31 in the longitudinal direction. A bracket 32 slidably supports the rod 31 and is fixed to the bottom surface of the lifting table 20. Reference numeral 33 denotes a plate rotatably provided at the tip of the rod 31 and has a shape of a divergent end that widens toward the side opposite to the rod 31.

Numerals 34a and 34b are levers arranged so as to face each other with one end having the plate 33 in between and the other end having the guide rail 21 in between, and one end side of which is a rotatable roller 35a, 35b is provided with pads 36a and 36b on the surface facing the guide rail 21 on the other end side, and is rotatably connected to each other by a pin 37 at an intermediate portion of the levers 34a and 34b. It is fixed on the bottom of the lift 20.

A spring 38 is mounted between the levers 34a and 34b so that the rollers 35a and 35b always come into contact with the side surface of the plate 33 and sandwich the plate 33 from the side surface.

With such a structure, when the elevator 20 is moved up and down along the guide rail 21 by the wire rope 3, the rod 31 is extended in the longitudinal direction by the drive device 30. Thus, the rollers 35a and 35b are both in contact with a narrow position near the rod 31 of the plate 33, and the levers 34a and 34b have the pads 36a and 36b together with the guide rail 21 at a predetermined clearance as shown in FIG. Since the maintained state is maintained, the lift table 20 can be freely raised and lowered without any obstacle.

On the other hand, when the lift 20 is landed on the level of an arbitrary parking room, the driving device 30 operates to move the rod 31 in the retracting direction (direction A in FIG. 3), and the plate 33 also moves in the direction A. As a result, the rollers 35a and 35b are guided by the side surface of the plate 33 and move in the directions away from each other against the spring force of the spring 38 as shown in FIG. That is, the levers 34a and 34b rotate about the pin 37 in the direction in which the pads 36a and 36b come close to each other, so that the guide rail 21 is pinched with a predetermined force.

Therefore, the lift table 20 is held by the friction between the pads 36a and 36b and the guide rails 21, so that the vehicle mounted on the pallet 23 is moved between the parking room and the lift table by the palette carrier 22. Even if the hanging load of the wire rope fluctuates during the movement, the lifting platform 20 does not move in the vertical direction and the level does not shift, so that the loading and unloading of the vehicle can be carried out extremely quickly and safely.

Then, when the movement of the automobile to the parking room or the lifting table 20 is completed and the lifting table 20 is to be lifted and lowered, the driving device 30 is operated in the opposite direction to move the rod 31 in the direction B in FIG. When they are moved, as the plate 33 moves in the B direction, the rollers 35a and 35b move toward each other while being pressed against the side surface of the plate 33 by the spring force of the spring 38, so that the levers 34a and 34b move toward the pins. The pads 36a and 36b rotate around 37 in a direction away from each other to release the holding of the lift table 20 as shown in FIG. As a result, the elevating table 20 can be freely moved up and down.

Since the expansion / contraction speed of the rod 31 by the drive unit 30 is constant, the pads 36a and 36b are guided when the traveling surfaces of the rollers 35a and 35b of the plate 33 are straight as shown in FIGS. 3 and 6. Since the rail 21 is released in an instant, the expansion and contraction state of the wire rope 3 changes at the moment of release, and the elevator 20 may swing upward and downward. For example, as shown in FIG. 7, it is easy to solve the swinging problem of the lift table 20 by devising the curved shape so that the releasing operation of the pads 36a and 36b is gradually performed.

In the above description, an example in which the lifting table holding device is provided on the bottom surface of the lifting table has been illustrated and described. However, as shown in FIG. It may be installed vertically on the side surface of the base 20 and used, and is not limited to the embodiment.

As described above, according to the present invention, even if the load on the lifting platform such as an automobile moves, the level fluctuation of the lifting platform due to the expansion and contraction of the wire rope can be suppressed to a small level, so that the parking room is always in a direct state. It can be landed on the floor etc. and the time required for loading and unloading can be greatly reduced. It is also safe because the load can be moved very smoothly.
