Description

 The invention relates to the field of construction of buildings and structures and can be used as a parking garage, elevator warehouse of trade enterprises, catering, libraries, hotels, etc.

 A mechanized warehouse is known (US Pat. No. 4,674,602, class B 66 B 11/06, E 04 H 6/11, 1987) using a paternoster (continuous lift), in which the load carriers the cargo cradles for storing vehicles are suspended from a carrier cable according to the principle weight pendulum stability.

 Design disadvantages are non-compactness (low capacity of the structure in terms of indicator: built-up area per vehicle), complexity and low efficiency of mechanisms due to the need to move the load carriers in two directions (vertical and horizontal) and over long distances.

 Known elevator lift (AS USSR N 937309, class B 66 B 9/00, 1979), containing a shaft with several (one below the other) doorways, a cabin unit with cabins located one below the other. The cabin unit is located in the shaft on the covering rails. The drive of the cabin block is installed on the ceiling above the enclosing rails and is an electric winch, to the cables of which cabin blocks are suspended by the principle of weighted mutual balancing.

 In the case of using this elevator lift as a holder (device for receiving, storing and issuing storage objects), it will be a structure of considerable height, which is determined by the height of the shaft and the height of the superstructure above the upper ceiling of the shaft, where the cabin unit drive is located. The shaft height, in turn, is determined by the stroke length of the cabin block from the lowest to the highest position at which all cabs will be able to load from one level (ensuring loading and unloading of all cabs by increasing the number of loading and unloading levels leads to an increase in height and area of access facilities). In settlements with dense urban development, such a structure, especially when it is a high-rise structure of several sections of elevators, will create additional (negative) loading of the architectural landscape, increase the shading of streets, squares, etc.

 The purpose of the invention is to reduce the height of the elevator shaft used as a holder, and also to improve the operational properties of the device.

 To achieve these goals in a known device containing a shaft with a doorway, a cabin unit with cabs located one below the other, which is located in the shaft on the enclosing guides and the drive of the cabin unit, the shaft does not have a top floor and its cavity communicates from above with the outer space. The cabin block has male guides that are located outside the cabin block along the female rails and are connected to them by means of supports that allow the cabin block to be pulled out of the shaft. The lower part of the cabin block is equipped with a displacement tank, and the part of the shaft cavity located below the doorway is a tank equipped with a water pipe (this provides the possibility of emergency extension of the cabin block from the shaft through the use of buoyant water forces).

 The drawing shows a parking lot using the claimed device, a partial section.

 Car parking contains a shaft with an underground part 1 of depth t and a superstructure 2 of height h. In the superstructure there is a doorway with sliding doors 3. In the mine, on the enclosing guides 4, a cabin unit 5 with cabs located one below the other is mounted. Under the cabin block there is a displacement tank float 6 with foam core inside.

 The drive of the cabin block is installed outside the enclosing rails 4 (under their upper ends) and is a winch 7 with a rope 8. One end of the rope is mounted on a float 6, and the other on a counterweight 9, which has the ability to move parallel to the cabin block 5 along the rails 10 installed in the lateral recess of the mine walker (in the counterweight shaft).

 The cabin unit 5 has externally covered guides 11. At the upper ends of the enclosing guides 4 and at the lower ends of the enclosed guides 11, supports 12 are mounted to fix the cabin unit from lateral movements with the possibility of extension from the shaft and return to the initial (lowermost) position.

 In order to provide the possibility of emergency extension of the cabin block from the mine due to the use of buoyant forces of water (in case of flooding of the mine with ground and rainwater, in case of failure of the drive of the cabin block, etc.), the float 6 has a buoyancy reserve sufficient to maintain afloat a fully loaded cabin block 5. The part of the shaft cavity located below the doorway is a tank equipped with a water pipe 13 (the pipe provides water movement in two directions of discharge and filling). To prevent rainwater from entering the mine, the cabin unit has a roof with a canopy 14.

 Other design options are possible. For example, a mine may not have an above-ground superstructure 2 and, conversely, have a superstructure of great height and not have an underground part 1. The mine may have several doorways for the entry and exit of cars located one below (above) the other, which reduces the height of movement of the cabin block from the lowest to the highest position. The drive of the cabin unit can be installed on it itself, for example, in the float 6, and also have other well-known suspension schemes of the load carrier and counterweight. It is possible to use cabin units, hydraulic, screw and other ejectors, doubled according to the principle of weighted mutual balancing of the cabin unit, etc.

 The retractable design of the cabin block allows you to reduce the height of the structure by several times compared with the base object of the prototype (with the same indicators of the capacity of the cabin block and the built-up area of the structure).

 Car parking with multi-tier cars moving out of the elevator shaft of the elevator carrier in terms of capacity (building area per car) exceeds all parking garages known in the world, and among the well-known mechanized parking garages it is the simplest in design.
