Description

The invention relates to structures for parking mainly cars.

A device for a two-level parking of cars, 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 [1]. 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.

Known roadside device of 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, mounted in a concrete base, installed near the lane [2].

A device for two-level parking of cars installed in the garage [3]. The device consists of a platform for parking cars located in the garage on the second level, mounted movably in the vertical direction on a rotating rack, mounted 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 in the range of 75-90 ° and is indicated on the drawing to the description. 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 design of the mounting of the rack 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 description indicates that the platform makes a combination of movements: rotation, lowering, sliding, lifting, but the technical means by which these movements are performed are not disclosed. The technical effect obtained depends on the technical means used — reliability, energy costs, and the cost of parking the car, the time spent on its portable movement, necessary when performing parking.

The technical problem posed in the invention is to simplify the design of the two-level parking device while reducing the time spent on the portable movement of the second level platform.

The problem is solved in the device for parking cars, consisting of a rack fixed in the base; a second level platform mounted on a rack with the possibility of its portable movement from the second level to the first level, consisting of turning to a location above the car lane, moving down to the lane and vice versa, having a central section occupied by the car and a peripheral section; a guide device eccentrically located and rigidly attached to the peripheral portion of the platform and covering the rack; platform drive; the platform has a thrust bearing covering the rack from the side of the platform facing the base; the guiding device is made on the rack and has a straight section for vertical movement of the platform and a screw section at the end of the rack for rotating the platform at an angle π or π / 2; the platform drive has at least one hydraulic cylinder mounted between the base of the platform and the thrust bearing.

The technical effect consists in simplifying the design of the device, reducing its cost and reducing the time for portable movement of the platform with the car from the vehicle lane to the upper level and vice versa.

The technical effect is achieved due to new distinctive features of the device, namely:

the platform has a thrust bearing covering the rack from the side of the platform facing the base,

the guiding device is made on the rack and has a straight section for vertical movement of the platform and a screw section for rotating the platform by an angle π or π / 2 at the end of the rack with a helix angle that significantly exceeds the angle of friction,

the platform drive has at least one hydraulic cylinder mounted between the base of the platform and the thrust bearing.

Distinctive features of the device are not found when studying the prior art, are new and do not follow from the prior art.

The rack-mounted guide device, which has a straight section for vertical movement of the platform and a screw section for turning the platform at an angle π or π / 2, allows you to use only the hydraulic cylinder installed between the base and the thrust bearing to drive the platform. This design is simple and has a reduced cost, the thrust bearing can significantly reduce the friction moment when the platform is rotated. The use of a hydraulic cylinder in the drive allows to improve the dynamics of the platform and reduce the time of its transfer from the lane to the upper position.

Figure 1 shows the design of the device; figure 2 - design of the guide device in section aa in figure 1; figure 3 - section bb in figure 2; Figures 4 and 5 show a scan of the surface of the upper end of the strut with a screw guide, which enables the platform to rotate by an angle π / 2 and π, respectively; Fig.6 is a plan of placement of two-level car parking devices in the parking area perpendicular to the car lane; Fig.7 is a plan of placement of devices for two-level parking of cars in the parking area along the lane of cars.

The two-level car parking device consists of (Fig. 1): rack 1, fixed in the base 2; platform 3 of the second level mounted on the rack 1 with the possibility of its portable movement from the second level to the first level, consisting of turning to the location above the lane of cars, moving down to the lane and vice versa, having a Central section 4 occupied by the car, and peripheral section 5; a guide device 6 of the platform 3, eccentrically located and rigidly attached to the peripheral portion 5 of the platform 3, covering the rack 1 and interacting with the guide device 7 of the rack 1; a platform drive having at least one hydraulic cylinder 8 mounted between the base 2 of the platform 3 and the thrust bearing 9 covering the rack 1 from the side 10 of the platform 3 facing the base 2; the guide device 7 of the rack 1 (Figs. 2, 3) is made on the rack 1 and has a straight section 11 for vertical movement of the platform and a screw section 12 at the end of the rack to rotate the platform by an angle π or π / 2.

In one embodiment, the guide device 7 of the rack 1 has at least one rectilinear guide fixed in the form of a channel 13, which passes into the screw section 12 at the upper end of the rack (Figs. 4 and 5). The guide 6 of the platform 3 has rollers 14 fixed therein, located in the channels 13 of the guide device 7 of the rack 1. A latch 15 can be installed in the guide 6 (Fig. 1).

The angle of inclination of the helix (φ) on the screw section 12 is taken to be a large friction angle of the rollers 14 of the guide platform 3 relative to the guide channels 13, mounted on the rack 1.

Based on the practice of designing non-self-locking screw mechanisms, the angle φ (Figs. 4, 5) is taken to be large 17 °.

The two-level car parking device is installed on the parking area 16 so that the rack 1 is as close as possible to the lane 17 (Fig.6). When several platforms 3 are located above an area of 16 perpendicular to the lane, the distance between the racks of adjacent devices should be sufficient to rotate the platform. With this arrangement of devices, the angle of rotation of the platform is π / 2, and the utilization of the parking area is determined as the ratio:

where S is the value of the parking area, S _PL is the value of the platform area, n is the number of two-level parking devices installed on the parking area.

To increase the utilization rate of the parking area up to 2 devices are positioned so that the platforms 3 above the parking area 16 are installed along the lane 17 and for the car to enter the platform when it is moving along the strip, the platform must be rotated through an angle π (180 °) (Fig. 7) , and for entering from a direction perpendicular to the lane, by an angle π / 2 (90 °).

The initial state of the two-level car parking device is the platform at the top above the parking area. When the fluid is discharged from the hydraulic cylinder 8 under the action of the weight of the platform 3 and the vehicle, the platform, dropping down, rotates around the rack 1 along a helical line at an angle π / 2 (Fig.6) or an angle π (Fig.7) and, taking a position above the strip, falls down on the rack 1 with a straight section 11, taking a position in the lane 17. After entering the central part of the platform, the car is fixed on it. When applying the working fluid under pressure to the hydraulic cylinder 8, the platform with the car first rises up to the entrance of the guide rollers 14 into the screw part of the guides 7, then turns during further lifting and occupies the upper position above the parking area 15. In the upper position, the platform is held by a hydraulic lock (not shown ) or mechanical lock 15 (figure 1).

The device allows to reduce the area required for parking cars by 1.5-2 times in comparison with their parking at the same level.
