Abstract

PURPOSE:To improve the extent of economical efficiency in view of construction and maintenance by simplifying the structure of a driving sprocket wheel in a power transmission mechanism for a vertical circulating type parking system. CONSTITUTION:The proper numbers of toothed plates 31 provided with partial teeth of proper numbers are arranged on a pitch circle 29 in size corresponding to the specified turning ratio and attached to the side of an upper sprocket wheel 23 circulating an endless link chain 17 hangingly supporting a car mounting cage 11 at regular intervals. Since each of these toothed plates 3 is adjustable of its position in the radial direction of the pitch circle, it can easily cope with any pitch variation due to the elongation of a driving chain 47 to be secularly produced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical three-dimensional parking system for passenger cars, and more specifically, a vertical circulation system in which vehicles are mounted in a plurality of cages and circulates in a ferris wheel type by a link chain. The present invention relates to a power transmission mechanism of a parking device.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 4, a vertical circulation type parking system has a car chain 101, ..., 101 suspended from an arm 103 ,.
It is cyclically driven by 05. In the power transmission mechanism of the conventional vertical circulation type parking device, as a transmission mechanism for rotationally driving the upper sprocket wheel 107, a normal drive sprocket having a sprocket groove 113 that engages with the pin 111 of the drive chain 109 is provided on the entire circumference. Wheel 1
It is general that 15 is directly connected to the upper sprocket wheel 107, and the drive sprocket wheel 115 is rotated through the drive chain 109 by an appropriate power source 117.

[0003]

However, when the drive chain 109 rotates the drive sprocket wheel 107, the force for transmitting power is the drive chain 1.
09 pin 111 and drive sprocket wheel 107
The teeth 119 are not evenly applied. Therefore, when the rotation speed is low, the teeth 119 of the drive sprocket wheel 107 do not necessarily have to be provided over the entire circumference.

Based on the above consideration, an object of the present invention is to simplify the gear cutting process of a large-diameter sprocket by using the driving sprocket teeth as partial teeth and reduce the weight to reduce the manufacturing cost, and in terms of construction and maintenance. An object is to provide a highly economical multi-story parking system.

[0005]

In order to achieve the above object, the multi-story parking apparatus of the present invention has an endless link chain stretched between a pair of sprocket wheels vertically spaced from each other. In a multi-level parking apparatus in which a plurality of cages for mounting on a vehicle are suspended and supported on a link chain via an arm, and the cage is vertically circulated by rotating the upper sprocket wheel by an appropriate drive mechanism. Regarding the rotational driving force transmission, an appropriate number of toothed plates having an appropriate number of partial teeth are arranged at equal intervals on a pitch circle of a size corresponding to a required rotation ratio on the side surface of the upper sprocket wheel. , Adjustable radial position.

[0006]

[Function] On the side surface of the upper sprocket wheel that circulates the endless link chain that suspends and supports the cage for mounting on the vehicle, the partial teeth having an appropriate number of teeth are provided on the pitch circle of a size corresponding to the required rotation ratio. Since the appropriate number of toothed plates are arranged and mounted at equal intervals, any part of the teeth of the toothed plate can be engaged with the pin of the drive chain to transmit the rotational driving force. Therefore, since there is no base body as a wheel for the drive sprocket, the upper sprocket wheel also serves as the connection with the drive shaft. For this reason, the weight of the drive wheel for rotating the cage circulation link chain is reduced, and mass production of the toothed plate having only partial teeth is facilitated in the same process, resulting in reduction of material cost and manufacturing cost. Also, since a bearing for this wheel portion can be used for light loads, this also contributes to economy in terms of construction and maintenance.

Further, since the toothed plate can be attached by adjusting the position in the radial direction of the pitch circle, the pitch fluctuation due to the elongation of the chain that occurs over time can be easily dealt with by adjusting the pitch circle. ..

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the whole of a multi-level parking apparatus according to the present invention, and a front portion of a frame of the entire apparatus is omitted for easy understanding. FIG. 2 is a sectional view taken along the line II-II in FIG.

In FIG. 1, 11 is a vehicle for each.
It is a cage that stores one by one, each arm 13, ..., 1
3 is suspended and supported in a freely suspended state. Arm 1
3, ..., 13 are connected by connecting pins 15, ..., 15 respectively to form a link plate of an endless link chain 17. Further, guide rollers 19, ..., 19 are provided on the arms 13, ..., 13 and the guide rollers 19 ,. The cage 11 is regulated so as to move along a vertical track without being bent.

Connecting pin 1 of the endless link chain 17
.., 15 move the endless link chain 17 as the upper sprocket wheel 23 rotates while engaging with the sprocket grooves provided on the outer periphery of the upper sprocket wheel 23 at the upper side. Endless link chain 17
Is guided along a fixed guide 25 having a substantially semi-circular shape below. By rotating the upper sprocket wheel 23, the cage 11 circulates vertically.

As shown in FIG. 2, the same mechanism as described above including the arm 13 for suspending and supporting the cage 11 and the endless link chain 17 is symmetrically arranged in front of and behind the apparatus with the cage 11 interposed therebetween. The respective endless link chains 17 arranged before and after this are interlocked by a main shaft 27 that drives the opposing upper sprocket wheels 23, 23 in a chain. The main shaft 27 includes a drive chain 47 for rotating the upper sprocket wheels 23, 23,
The rotational driving force of the motor 51 is transmitted to the motor 47 via the speed reducer 53. 55 and 55 are idle wheels that clamp the drive chain 47 to adjust the tension, and at the same time drive chain 47
Determine the orbit of.

On one of the upper sprocket wheels 23,
An appropriate number of toothed plates 31, ..., 31 having three teeth are arranged on a pitch circle 29 having a size corresponding to a rotation ratio required for circulating the cage 11 and are attached at equal intervals. ..

The mounting mechanism will be described with reference to FIG. Reference numeral 33 is a bracket integral with a liner base 35 fixed to the side surface of the upper sprocket wheel 23, and adjustment bolts 37, 37 are screwed and inserted therethrough. The toothed plate 31 is fitted on the liner base 35 between the guides 39, 39 provided on both side ends with the tooth portion 41 facing outward.

The toothed plate 31 is provided at the leg end of the adjusting bolt 37.
When the adjusting bolt 37 is screwed so as to press the bottom portion 43, the tooth portion 41 moves outward. Therefore, by adjusting the adjusting bolt 37 appropriately, the pitch circle 2
9 can be scaled up or down. The movement of the toothed plate 31 on the liner base 35 is performed along the elongated hole 45, and when proper engagement with the drive chain 47 is obtained, a fixing bolt 49 that is inserted through the elongated hole 45 is tightened. Fix the tooth plate 31 in that position and set the pitch circle 29
Hold.

The upper sprocket wheel 23 is rotationally driven by transmitting the rotational driving force of the motor 51 to the drive chain 47, which is wound and meshed with the plurality of toothed plates 31, through the reduction gear 53. Numerals 55 and 55 are idle wheels for adjusting the tension of the drive chain 47 and determining the orbit of the drive chain 47. In this embodiment, a motor is used for the driving force, but
Other drive sources can also be used.

When the vehicle is loaded or unloaded, the motor 51 is driven to circulate the link chain 15 to move the required cage 11 to the position S shown in FIG. The load causes permanent extension of the drive chain 47, and the accumulated pitch error becomes large particularly in the case of engagement with a large-diameter sprocket. In such a case, loosen the fixing bolt 49 and adjust the adjusting bolt 37,
When the pitch circle is enlarged to obtain proper engagement with the drive chain 47, the fixing bolt 49 is tightened again to fix the toothed plate 31 at that position. It is possible to adjust the pitch circle 29 to be suitable for the drive chain 47 which is stretched in this way.

[0017]

According to the vertical circulation type parking apparatus of the present invention,
Regarding the rotation drive of the upper sprocket wheel that circulates the link chain that suspends and supports a plurality of cages for vehicle mounting, the sprocket teeth are provided partially and evenly on the required pitch circle on the side surface of the upper sprocket wheel for driving. The elimination of the base body of the sprocket wheel not only reduces the weight of the drive wheel that rotates the cage circulation link chain, but also eliminates the need to manufacture an expensive large-diameter sprocket. Since the tooth plate can be easily mass-produced in the same process, material cost and manufacturing cost are reduced. Also, the bearing of this wheel part can be used for light loads, and the toothed plate can be attached by adjusting the position in the radial direction of the pitch circle. Fluctuations can be compensated for in the pitch circle preparation and prolong the replacement cycle for the drive chain. This also makes it possible to achieve economy in terms of construction and maintenance.
