Description

The invention relates to the field of construction and can be used in the design and construction of multi-storey garages and parking lots serving various enterprises: large stores, stadiums, exhibitions and fairs, as well as manufacturing enterprises and offices.

Known mechanized multi-storey garage, which is a building having a height of several tiers (floors). On each tier there are separate sections with longitudinal and transverse guides located between the comb platforms serving for parking. Cars are loaded into the garage by a cable car lift, on which two freight platforms are installed: the lower, moving along the longitudinal guides, and the upper, articulated, delivering the car along the transverse guides to the parking lot (see RU 210144 C1, 10.01.98).

Known parking lot, made in the form of a tower, equipped with devices for transporting and installing cars on pallets in suitably equipped cells. The parking lot is designed in several layout options. There is an option in which the cells are located on both sides along the lift. The hoist consists of a hoist hoist drive and a hoisting platform that moves vertically along the rails. The platform is equipped with a mechanism for moving a car mounted on a pallet from the platform to the cell of the parking tower and back, as well as a turntable for turning the car.

In another embodiment, the cells are located on both sides across the lift. The lifting platform in this case has a width equal to the width of the cells adjacent to the lift, usually two to three. An additional platform is installed on the main platform, which moves along the first along the front of the cells using a cable or chain drive. The second trolley carries the mechanisms for moving and turning the car mounted on a pallet (see US 5314284, from 05.24.94).

The disadvantages of the described construction include saturation with mechanisms, significant metal consumption, especially in the second embodiment, and, as a consequence of this, increased energy consumption.

The closest is a multi-storey mechanized car park, designed as a ground or buried building, in the center of which there is a mine with a lift, on both sides of the shaft on the floors there are parking places for cars installed on pallets for transporting cars from the lift to the parking places and back (see WO 99/06655 A1, 02/11/1999).

The disadvantages of the described design is the inefficient use of the built-up area and the insufficient reliability of the system.

The technical result of the invention is the creation of a multi-storey mechanized car park free of the above disadvantages, providing the possibility of uninterrupted car parking and, in violation of the prevailing notions, an attempt to create a much more economical system for delivering cars to parking lots and issuing them to their owners. At the same time, better use of the built-up area of the site allocated for the construction of the parking lot is achieved.

The technical result is achieved by the fact that in a multi-storey mechanized car park containing a ground or underground building, in the center of which there is a shaft with a lift, on both sides of the shaft on the floors there are parking places for cars installed on pallets for transporting cars from the lift to the parking places and back, parking places are equipped with two drive rolls with a common drive, the lift has a drive located on top of the shaft and consisting of an electric motor, gearbox with two outputs shafts mounted with the possibility of rotation using worm or bevel gears, two parallel shafts with two drive sprockets mounted on each of them, on which drive chains are worn, forming closed loops stretched from below by two sprockets mounted on a common shaft to form two pairs of drive chains located at the ends of the shaft, on each of which at least two shelves are suspended for raising and lowering pallets with or without cars to be parked, and LCI equipped with non-driven roller conveyors for moving the trays and rollers which are configured to roll along guide rails mounted in the shaft ends.

It is possible to carry out a multi-storey mechanized car park with shelves suspended on drive chains, each of which is made with a length equal to the width of the pallets, and in the form of a vertical wall, in the lower part of which there is a bracket on which non-drive roller tables are installed, consisting of worm gearboxes connected between using flexible couplings high-speed shafts, intermediate shafts, low-speed shafts with running rollers mounted on them with flanges, and in the upper part of the shelves, to the vertical wall two brackets with holes are welded, in which a shaft is mounted on the bearings, the ends of which are made in the form of axes of drive chain links, and in the lower part of the vertical wall on the side opposite to the roller table, two bearing housings are mounted with axes on which they are mounted for rotation in the plane perpendicular to the wall, and rolling along the guide rails of the roller with flanges, while the guide rails are installed vertically in the lift shaft.

It is possible to carry out a multi-storey mechanized car park with non-driven roller tables mounted on suspended shelves with the possibility of rotation by means of drive roller tables installed at parking places, while splined shafts with spline bushings having spherical ends included are installed on the output ends of the drive roller tables by means of shortened cardan shafts in the conical holes of the coupling halves installed on the output ends of the high-speed shafts of the non-driven roller tables installed on the shelves ivodnyh chains, wherein the ends of the sleeves and splined conical hole coupling halves are made with a surface having a high coefficient of friction.

A feature of the proposed design of the parking lot is the fact that two other shelves, previously located on the idle branches of the chains, are used to raise the next car. To install each subsequent car, you do not need to lower the lift, since there are already free shelves of the lift. System performance increases significantly. A sufficiently heavy cargo platform is replaced by shelves having a lower mass, which allows to reduce the lifting capacity of the lift by almost half and, accordingly, reduce energy consumption.

The reliability of the parking compared to the described analogues is achieved by reducing the number of mechanisms and reducing their metal consumption.

The invention is illustrated by the following drawings:

The multi-storey mechanized car park is a multi-storey building 1, in the center of which there is a lift shaft. On each floor of the building, on both sides of the mine, on the floors of floors and on the floor of the lower floor, drive rolls 2 are installed in pairs, on which pallets 3 are installed with or without cars. The drive roller tables form, depending on the length, one or more parking spaces on each side of the lift shaft. Entrance (and exit) to the building is made through gate 4 located on one or both sides of the mine.

Lift 5 has a drive located on the upper floor of the parking building. The drive consists of an electric motor 6, a cylindrical gearbox 7 with two output shafts, rotating with the help of worm gearboxes 8 two drive shafts 9 with two drive sprockets mounted on them 10. The drive chains 11 are put on the sprockets, forming closed loops. From the bottom, the loops are pulled by sprockets 12, also installed in pairs on a common shaft 13. On each pair of chains 11, shelves 14 are used to raise (lower) the pallets with cars. The shelf, the length of which is equal to the width of the pallet, is made in the form of a vertical wall, in the lower part of which a horizontal bar is welded. Two brackets 15 with holes are welded from above to the vertical wall, in which a shaft 17 is mounted on the bearings 16, the ends of which serve as the axes of the links of the drive chains 11. Thus, the shelf hangs on the drive chains using the shaft and can rotate freely around its axis. In the lower part of the vertical wall of the shelf there are two bearing housings 18, in which the axles 19 are mounted, on which the rollers 20 rotate with the help of bearings. The rollers roll along the guide rails 21, vertically mounted in the elevator shaft, two on the side of the working branches of the chains.

On the horizontal slats of the shelves 14, non-driven roller tables 22. The ratio of the number of teeth of the worm and the worm wheel is selected so that the gearbox is self-braking. This is necessary because of the reasons that no brakes are installed on the roller tables, and therefore, power supply to the roller tables is not required. For the same reasons, the roller tables are made non-powered.

The drive of the roller conveyors 22 installed on the shelves of the elevator is carried out by the drive roller conveyors 2 installed in the parking lots of the cars adjacent to the elevator shaft. To do this, at the ends of the high-speed shafts of the non-driven roller tables facing the drive roller tables, coupling halves 26 are installed having a conical bore.

The drive roller tables 2 are constructed in the same way as the non-driven roller tables 22. They are made with worm gears 23 connected by cardan shafts 24. Rollers with flanges 25 are installed on the slow-moving shafts of the gearboxes, which serve to move pallets with cars. The roller conveyor drive (not shown in the drawings) consists of an electric motor, a gearbox with two output shafts connected to worm gearboxes, and in turn, connected to the high-speed shafts of the conveyor gearboxes.

At the ends of the high-speed shafts of the gearboxes of the drive roller tables facing the hoist, by means of shortened cardan shafts 27, spline shafts 28 are included, which are included in the spline bushings 29. The spline bushings end in a solid section. The ends of the spline bushings have a spherical surface. The spline sleeves through the bearings 30 are fitted with lever clamps 31. The levers rotate around the axis of the hinges 32 under the action of hydraulic cylinders 33, the rods of which are also pivotally connected to the levers. In turn, the hydraulic cylinders are pivotally connected to the brackets 34.

Work in a multi-storey mechanized car park is as follows. Pallets 3 are installed at all parking lots of vehicles formed by pairwise installed drive rollers 2, having a common drive. Trays are not available only on rolling tables adjacent to the lift shaft on the floor located at the level of road access roads. When a car pulls up to the parking lot for parking, the operator determines the place of its installation (floor, cell) and calls the pallet 3 located on the corresponding cell. If the pallet 3 is located in a cell adjacent to the elevator 5, the elevator drive is switched on, and the direction of its movement depends on the location of the shelves 14 on the drive chains 11. The shelves closer to the given floor are called up, regardless of where they are located - on workers or on idle branches of chains. When the shelves are stopped on a given floor, the mechanisms for the movement of the pallet are turned on.

The hydraulic cylinders 33 are turned on (a single hydraulic line is constantly under pressure) and the levers 31 are turned, which, due to the displacement of the splined bushings 29 along the splined rollers 28, press the bushings face-on to the coupling halves 26 mounted on the high-speed shafts of the worm gearboxes 23 of the non-driven roller tables located on the shelves 14 of the elevator. At the same time, the drives of the live rolls 2 are turned on. The rotation from the shafts of the drive live rolls due to the torque created by the friction of the spline sleeve 20 having a spherical surface and the coupling half 26 having an internal conical surface is transmitted to the non-driven roll tables. In this case, the pallet moves first along the roller tables of the cell, and then along the roller tables installed on the shelves of the elevator. When the pallet is completely moved to the elevator shelves, the roller tables are turned off.

The lift turns on and lowers the pallet to the lower floor, where the car entry and exit section is located. The operator opens gate 4 and the car enters the pallet. The driver turns off the engine, puts the car on the parking brake or at speed and leaves the car. The roller tables are turned on and the pallet with the car drives into the lift as described above. The car is lifted to a given floor and moved to the desired cell.

Shelves 14 of the lift, suspended on the shaft 17, can freely rotate on bearings 16 around the axis of the shaft. When the shelves are on the working branch of the chain, under the influence of the moment from the own mass and mass of the pallet and the car (when the shelves are loaded), the rollers 20 are pressed against the guide rails 21. When the elevator moves, the rollers of the shelves roll freely along the rails. The vertically mounted guide rails 21 terminate at the top and bottom of the drive 10 and tension 12 sprockets. When the shelves go beyond the guide rails (they are always unloaded at the same time), due to the possibility of rotation around the axes of the shafts 17 they sag freely and in this position move on the idle branches of the chains 11. To enable the rollers 20 to freely enter the rails 21, the ends of the rails 21 are bent .

The chains 11 of the elevator 5 work from a common drive, so the movement of the shelves is performed at the same speed, which ensures strict parallelism of the vertical movement of the shelves of the elevator and, accordingly, pallets with cars. Elastic vertical vibrations of the chains 11 are practically absent. These circumstances make it possible to ensure reliable operation of the automatic lift control systems.
