Description

The invention relates to structures for parking cars: cars, off-road vehicles, vans, but mainly cars.

A device for storing two cars [1] is preferably of the garage type, consisting of a floor section for placing the first car and a roof section for placing the second car, rigidly interconnected and forming a single structure, a mechanism for raising and lowering the structure into a recess made below the road level so that the roof can be installed at the level of the road. The lifting and lowering mechanism is made in the form of a cylinder with an electro-hydraulic drive.

The first disadvantage of the device is that it occupies a large volume below the ground level, which is undesirable for two-level parking lots, for example, located on city squares near shopping malls, government and public organizations. [Link to parking area regulations]. The second drawback is the high complexity and cost of protecting a large underground structure from the entry of ground and surface waters.

A device for two-level parking of cars (DPA), consisting of two interconnected platforms that can rise and fall, as well as rotate around a horizontal axis using drive mechanisms, occupying an inclined position [2, 3].

This device is also located in a recess below the level of the road and it is characterized by the above disadvantages of such a device.

A known system of two-level parking of cars [4], consisting of platforms located one above the other and rigidly interconnected for cars and a lever mechanism with a hydraulic drive for lifting the platforms. The system may include adjacent platforms with cars. Such a two-level parking system has the same disadvantages that are inherent in the above devices, since the system is located in a depression (bunker) below the ground level and in order to exit the car from the upper platform, lowering it to the road level, it is necessary to lower the lower platform into the bunker.

The advantage of the above devices and a two-level parking system is that in the absence of cars at both levels or only at the top, the upper platform can occupy a position at the level of the area on which it is located and should not rise above this area.

A well-known underground garage, including a platform for placing a car, mounted with the possibility of vertical movement in an underground bunker using a telescopic hydraulic lift, bushings fixed in the corners of the platform with the possibility of sliding along the guide racks located in the corners of the bunker [5]. The first drawback of this design of the platform with the guides is that when a difference in the friction forces arises in the guides, the platform skews relative to the vertical axis of the hydraulic lift, leading to a larger increase in the difference of the friction forces in the platform guides and possible jamming. The second drawback is the complexity of the design of the platform and the guides. The third disadvantage is the location of the platform, motionless in the horizontal plane, and the associated impossibility of its different orientation relative to the lane of cars.

A known device DPA installed in the garage [6]. The device consists of a first-level site located in the garage, a platform for parking cars at the second level, above the first-level site, mounted movably in the vertical direction on a rotating stand fixed in a frame base. The platform is driven by a hydraulic or pneumatic drive or from an electric motor through a rack and pinion gear. The design of any drive in the description is not disclosed. The stand rotates in sliding bearings installed between the upper and lower ends of the stand and the upper and lower cross-members of the frame base. The angle of rotation of the strut in the bearings, necessary for the vehicle to enter the platform, is shown in the figure to the description and is in the range of 75-90 °. Means of rotation of the rack in the description of the invention are not disclosed.

A disadvantage of the known device is the complexity of the construction of the rack mount at the base in the form of a rectangular frame. In addition, the description does not disclose the design of the drives of the vertical movement of the platform relative to the rack and the rotational movement of the platform, that is, the portable movement of the platform from the second level, on which the car parked on the platform is stored, to the first level, on which the car enters the platform to rise to the second level and drives out of it, leaving the parking lot.

The invention of the roadside device of a two-level (or three-level) car parking having a second-level platform, movable in the vertical direction and rotated in a horizontal plane relative to the rack fixed in a concrete base installed near the lane [7] is known.

A known device DPA (prototype device) having a platform for parking a second car, movable in the vertical direction and rotating in a horizontal plane relative to the vertical rack, mounted in the base in the immediate vicinity of the lane [8]. Car parking at the first level of the parking space is performed at the upper position of the platform of the second level. Car parking on the second level platform is performed regardless of the presence or absence of the car on the first level of the parking space.

The invention provides various options for the location of cars in the parking space with respect to the lane: parallel or perpendicular to the lane, as well as various options for the position of the platform relative to the lane when the car enters the platform: along the lane, perpendicular to it and at an angle to the lane. The rotation of the platform during its portable movement from the state of car parking to the position in the traffic lane is performed at an angle from 45 ° to 180 ° depending on the position of the loaded car in the traffic lane.

Having advantages in cases where the DPA device is the only device in the parking area, this device has disadvantages in the case of installing many devices, namely: the constant location of vertical racks and platforms of the second level above the parking area, regardless of the presence or absence of parked cars on the second level, significantly worsens the composition of the area; low efficiency of double parking with their single placement.

The technical task is to create a DPA device that allows you to park the car on a second-level platform when it enters the platform both from a position parallel to the lane and from it and perpendicular to it and from a position at an angle to the lane, and in the absence of cars, the upper plane of the second platform level should be placed at the level of the parking surface of the first level.

The resulting technical effect of solving the problem is to reduce the time for parking and driving the car off the platform, to preserve the composition of the area on which the ADD devices are located, in the absence of parked cars and to increase the safety of drive elements (protection against vandalism).

The problem was solved in the design of the device of the DPA and in the placement system of the devices of the DPA both on the parking area and relative to the lane of cars.

The DPA device consists of a vertical rack fixed to the base; a platform mounted on a rack with the possibility of movement in the vertical direction and rotational movement in the horizontal plane to a limited angle not exceeding 180 °, for occupying the first level in the traffic lane and the second level above the parking area; bushings rigidly attached to the platform on its peripheral part; mechanisms and their drives, providing vertical and rotational movement of the platform; platform position locks at the second level; the base is made in the form of a well, the stand is telescopic and has a fixed part fixed in the well with a height less than the depth of the well and an axis mounted movably in the vertical direction, on the upper end of which there is a sleeve with a platform.

Various versions of the telescopic stand are possible.

In one embodiment, the fixed part of the rack has a central hole, and the lower part of the platform axis is located in the central hole of the fixed part of the rack, in another embodiment, the lower part of the platform axis has a central hole, and the fixed part of the rack is located in the central hole of the platform axis.

In further embodiments, the sleeve is attached at an angular portion of the periphery of the platform or at the periphery of the platform so that the center of the sleeve is located on the transverse axis of the platform.

To reduce the moment of friction between the sleeve and the upper part of the axis of the platform there is an end bearing.

In a preferred embodiment, to fix the position of the platform relative to the axis, there is a controlled brake installed between the sleeve and the upper part of the axis of the platform.

The above technical effect is provided by the distinguishing features of the device, namely: the stand is telescopic and has a fixed part fixed in the well with a height less than the depth of the well and an axis mounted movably in the vertical direction, on the upper end of which there is a sleeve with a platform.

A significant increase in the technical effect is achieved by creating a DPA system consisting of a parking area; at least one lane adjacent to the parking area; devices for two-level parking of cars installed in the parking area so that their racks are at a minimum distance from the lane; however, at least two devices are installed so that their racks are as close as possible to each other, and the distance between adjacent platforms is minimal.

There are various options for the arrangement of devices in the system relative to the lane: perpendicular to the lane or along it. The preferred option is that the platforms are installed above the parking areas along the lane.

If the parking area has a width greater than the width of two platforms and two lanes are adjacent to it, then the ADD devices are installed along each lane.

The maximum technical effect is achieved from the DPA system, in which at least one pair of devices is installed so that their racks are close to each other, and the distance between adjacent platforms is minimal. When the platforms are located along the lane, the coefficient of useful use of the parking area is close to two.

Figure 1, 2 shows the design of the devices of the DPA; figure 3 is a section aa of the device shown in figure 1; figure 4 - view In the drive mechanism of figure 1; figure 5 is a top view of the platform with the axis of rotation placed on the transverse axial line of the platform; Figures 6, 7, 8 show variants of arrangement of devices (Fig. 1) in DPA systems; Figures 9, 10 show variants of arrangement of devices (Fig. 5) in DPA systems.

The DPA device consists of (figure 1, 2): a vertical rack 1, fixed in the base 2 of the well 3; platform 4 mounted on a rack 1 with the possibility of movement in the vertical direction and rotational movement in the horizontal plane at an angle not exceeding 180 °.

The platform 4 has a central part 5, designed to accommodate the car, and a peripheral part 6 with fences 7 and an attached sleeve 8. The rack 1 has a body 9 which is motionlessly fixed in the base 2 and is less than the depth of the well and a vertical axis 10 that is movable in the vertical direction relative to the body 9 On the upper part 11 of the axis 10, a sleeve 8 and a platform 4 are installed, as well as a drive 12 for turning the platform, and the lower part 13 of the axis 10 interacts with the housing 9 and has dimensions consistent with the dimensions of the housing 9. On the upper part 11 of the axis 10 the lower end of the sleeve 8 is installed controlled brake 14, which is a latch of the angular position of the platform 4 in its upper position.

There are various versions of the rack 1. In one embodiment (figure 1), the stationary housing 9 of the rack 1 has a cavity 15, and the lower part 13 of the axis 10 is placed in the cavity 15 and has a plate 16 at the end, the side protrusions of which are included in the longitudinal grooves 17 in the cavity 15.

In another embodiment (FIG. 2), the lower part of the axis 13a has a cavity 15a, and the fixed body 9a is located in the cavity 15a and has a plate 16a at the end, the lateral protrusions of which enter the longitudinal grooves 17a in the cavity 15a.

To drive the vertical movement of the axis 10 and platform 4, a hydraulic cylinder 18 is installed on the base 2.

Possible location of the sleeve 8 on the peripheral part 6 of the platform 4.

In one embodiment, the sleeve 8 is attached to the peripheral part of the platform (FIGS. 1, 2), farthest from the longitudinal 19 and transverse 20 center lines of the platform 4. In another embodiment, the sleeve 8 is fixed to the peripheral part of the platform 4 so that the center of the sleeve 8 and axis 10 is located on the transverse center line 20a of the platform 4 (FIGS. 5, 9, 10).

To reduce the friction moment between the sleeve 8 and the upper part of the axis 10 there is an end bearing 21 (Fig.1, 2).

A significant increase in the technical effect is achieved by creating a DPA system consisting of a parking area 22, including parking areas 23 under platforms 4; at least one lane 24 adjacent to the parking area 22; DPA devices installed on the parking area 22 so that their racks 1 are at a minimum distance from the lane, with each two devices installed so that their racks 1 are close to each other, and the distance between adjacent platforms is minimal (Fig. 8).

There are various options for the arrangement of devices in the DPA system relative to the lane 24 both along the lane and perpendicular to it. The preferred option is that the platforms 4 are mounted above the parking areas 23 so that their longitudinal axial lines 19 are parallel to the lane 24 (6, 7, 8). For devices with a sleeve 8, connected so that the axis of the strut 13 intersects with the transverse axial line of the platform, only the option of placing the platform 4 along the lane 24 is possible (Fig.9, 10).

In the embodiment of the system (Figs. 7, 8, 11), if the parking area has a width greater than the width of two platforms and two lanes are adjacent to it, then ADD devices are installed for each lane. Moreover, the utilization of the parking area is close to 2.

The initial position of the platform 4 is at the upper level (figure 1). The hydraulic cylinder 18 is filled with liquid under pressure. To transfer the platform 4 to the lane 24 (FIGS. 1, 2), the brake 14 is turned off, the drive 12 is turned on, the platform is rotated by a predetermined angle to a position above the lane 24. Then the working cavity of the hydraulic cylinder 18 is connected to a drain tank (not shown) and under by the action of gravity, the platform 4 lowers into the lane 24. A parked car drives off the platform 4 or, if the platform 4 is empty, a car enters it. To raise the platform with the car, working fluid under pressure from the pump is supplied to the cylinder, in the upper position of the platform 4, the drive 12 is turned on and the platform 4 is rotated by a predetermined angle to its position above the parking area 22. The platform is fixed from turning by the brake 14, and by lowering it with a hydraulic lock integrated into the hydraulic system (not shown).

In the absence of cars at the lower level of the platform 4 can be lowered to the platform 23 below them, which allows to improve the overall composition of the area and serves to save from vandalism of the drive and control system devices DPA.

The mechanical bearing 21 provides a small amount of friction, which reduces the energy consumption for turning the platform with the car. The proposed device reduces the time to transfer the platform to the lane and vice versa.

The above technical effect is provided by the distinguishing features of the device, namely: the stand is telescopic and has a fixed part fixed in the well with a height less than the depth of the well and an axis mounted movably in the vertical direction, on the upper end of which there is a sleeve with a platform and an end bearing.
