Description

The invention relates to automobile construction and can be used for compact placement of cars and their storage.

Known mechanized garage-warehouse containing a supporting structure, coupled chain conveyors, each of which forms a closed chain circuit, enveloping the drive and tension sprockets mounted for rotation on the supporting structure. The garage-warehouse is equipped with load-carrying cradles connected with a chain by levers that contain rollers that are meshed with stationary guides [1].

The disadvantages of the described mechanized garage warehouse include insufficiently reliable fixing of the cradles (swinging during movement and displacement along the loading and unloading position), which leads to premature wear of parts and components of the mechanism. In addition, the design of the described warehouse garage does not provide synchronization of chain circuits. All this leads to a reduction in the service life of the mechanism and reduces its reliability.

Closest to the claimed solution is a mechanized parking of a vertical type, consisting of a metal frame with platforms fixed to it for placing cars, a drive with traction chains, and a control panel. The metal frame is made in the form of two load-bearing frames mounted on supports and connected by beams and turnbuckles. The bearing frames have guides for moving the links of the traction chains and a device for their tension. The platforms are equipped with rollers fixed with the possibility of interaction with guides made in the form of gutters of a U-shaped profile from straight and curved sections. The drive chain drive is mounted on the base frame. The rotation of the second carrier frame to the traction chain is transmitted through the shaft couplings, thereby achieving synchronous movement of both traction chains [2].

The disadvantages of this mechanized parking include insufficiently reliable fixation of the platform at the loading-unloading position (the possibility of rocking and moving along). Being at this position, the platform is located between two guides, while the platform pallet has no support, which leads to the occurrence of oscillatory movements both along and across the direction of movement, and, as a result, breakdowns and a decrease in the service life of the parking lot. In addition, the rotation to the traction chain of the second supporting frame is transmitted by the shaft through the couplings, which do not fully provide compensation for inaccuracies in the installation of large parts (supporting frames).

Also, each coupling is a rather complex product that requires precision in manufacturing. The use of couplings leads to an increase in the cost of the product.

The objective of the invention is to increase reliability and increase the service life of mechanized parking.

The problem is solved in that in a mechanized parking, including a metal frame, made in the form of sidewalls, interconnected by beams and turnbuckles, a drive with chain circuits and platforms fixed to them to accommodate cars, said chain circuits are located in rails mounted on the sidewalls, and equipped with chain tensioning mechanisms, and chain chain sprockets are interconnected by a shaft, with each said platform made in the form of a cross and a pallet connected by struts and equipped with rollers fixed to move along the guides-dampers mounted on one of the sidewalls, according to the invention, the said shaft connecting the chain sprockets is provided with a cardan joint, while the parking is additionally equipped with supports fixed to the parking foundation at the lowest sections of the guides-dampers equipped with elastic elements, and located with the possibility of contact with the rollers of the pallet of each platform, and on the cross of each platform installed elastic elements.

The invention is illustrated by drawings, where in FIG. 1 shows a mechanized parking, general view;

in FIG. 2 - callout A in FIG. one;

in FIG. 3 - callout B in FIG. one;

in FIG. 4 - mechanized parking, side view;

in FIG. 5 - callout B in FIG. 4.

The mechanized parking consists of a metal frame in the form of two sidewalls 1 and 2, mounted on the foundation and interconnected by beams 3 and turnbuckles 4. On the sidewall 2, located on the side opposite from the entrance to the parking lot, two guides are installed symmetrically relative to the central axis of the sidewall 2 5, made grooved and having straight and two curved sections in the upper and lower parts, located one above the other. Guides-pacifiers 5 are located at a distance from each other. On the foundation, at the lowest curved sections of the guides 5, fixed supports 6, consisting of an elastic element 7 and embedded 8. On the sidewalls 1 and 2 there are guides 9 in which the chain circuits 10 are placed, and the chain tension mechanisms 11. Each chain circuits 10 is equipped with brackets 12 for hinging platforms 13 on them. Each platform 13 consists of a cross 14, with elastic elements 15 mounted on one of its side parts, struts 16 and a pallet 17. Rollers 18 are fixed on the crosses 14 and pallets 17 with side ony guides-pacifiers 5. Rollers 18

- 1 023572 can be moved in guides-dampers 5. A drive 19 is mounted on the sidewall 1, connected via a chain gear to the chain sprocket 20 10. The sprocket 20 is mounted on a pivoting-rotary device 21 mounted on the sidewall 1. On the sidewall 2 with with the help of the pivoting device 21, a second sprocket is installed 20. The sprockets 20 of both sidewalls 1 and 2 are interconnected by means of the shaft 22, thereby achieving synchronized movement of the chain circuits 10. The shaft 22 is made integral and has a cardan joint 23. Mechanized The parking lot is equipped with a control system, a guard for the loading and unloading position with a safety circuit.

Mechanized parking is as follows. On the pallet 17, connected to the crosspiece 14 using racks 16, a free platform 13, located at the position of loading and unloading, upon receipt of an authorization signal, the car drives in. In this case, the pallet 17 of the platform 13 remains stationary due to the fact that it is fixed by the supports 6, the elastic elements 7 of which, located between the mortgages 8, dampen the vibrations of the platform 13 upon arrival of the car. Using the control system, the drive 19 is mounted on the sidewall 1, connected to the sidewall 2 with beams 3 and turnbuckles 4. The rotation is transmitted from the drive 19 through a chain drive to the sprocket 20 mounted on the pivoting device 21 of the sidewall 1. Next, the rotation is transmitted from this sprocket 20 to the sprocket 20 of the sidewall 2 by means of a shaft 22 connecting them. A universal joint 23 mounted on the shaft 22 allows you to compensate for design inaccuracies that may occur during the manufacture, installation and operation of the parking lot. The sprockets 20 drive the chain circuits 10 in motion along the guides 9 with the platforms 13 fixed to them using the brackets 12. The chain tension in the chain circuits 10 is regulated by the chain tension mechanisms 11. Next, the platform 13 starts moving at the loading and unloading position. In this case, the rollers 18 located on the pallet 17 of this platform 13 are rolled along the mortgages 8 of the supports 6. The elastic elements 7 of the supports 6 absorb the vibrations of the platform 13 during its movement. One of the rollers 18, located on the crosspiece 14 and one of the rollers 18, located on the pallet 17 of the platform 13 in the direction of its movement, enter the corresponding lower curved sections of one of the guides-dampers 5 depending on the direction of movement of the platforms 13. Next, the platform 13 continues the movement, the rollers 18 pass through the curved sections of the guide-damper 5 and go to its straight section. The implementation of the guides-callers 5 grooved and the ability to move the rollers 18 in them can reduce the oscillation of the platforms 13 during operation of the parking lot. When passing straight sections of guides-callers 5 platforms 13, the pallet 17 of the upper platform 13 is laid on the elastic elements 15 located on the cross 14 of the lower platform 13. Thus, all platforms 13 located on a straight line of guides-callers 5 move as a whole, which eliminates the vibrations of each platform 13 individually. All of the above reduces the wear of parts, increases the reliability of the design of the parking lot and increases its service life.
