The transport system includes two dependent displacement systems in three planes, namely:

- system of movement in vertical and horizontal directions

- depth moving system

To move in the vertical and horizontal directions, two parallel sets of vertical and horizontal guides are used, forming lattices parallel to each other. Each set is in the same plane, the guides are connected at the intersection points. Between these sets of rails there is a transportation device with eight wheels turning 90 °, four wheels for each set of rails; there are four wheels on each end of the transport device (one wheel in each corner). The wheels are placed in such a way that if one of their wheels is located at the intersection of the vertical and horizontal guides, then the other seven wheels are located at the intersection of the vertical and horizontal guides. For a one-time rotation of the wheels, a wheel rotation mechanism is used, which is driven by an electric motor. To transmit torque to the wheels, the drive wheel rotation mechanism is used, which is driven by an electric motor (electric motors). To fix the transportation device at the moment of turning the wheels by 90 degrees, a position synchronization device is used, consisting of four stops (stops may be, if necessary and sufficient, a different amount) with a feed drive (which is driven by an electric motor or an electromagnet) located on transportation device, and the required number of grooves located on the rails.

To move in depth, an additional guide system is used, consisting of two horizontal guides parallel to each other in the form of rails located perpendicular to the plane of horizontal and vertical guides; devices for translating the movement of a transportation device from vertical to movement in depth and vice versa. The system of moving in depth and the system of horizontal-vertical movement are interconnected, being one device.

The transport system also includes a control unit. It can work autonomously using the built-in microprocessor or commands to it can be submitted remotely; a manual control system using a human operator can also be used.

The system works as follows.

If you need to move the transport device 1 from position B1 to position, for example, I1 (along the path B1, D1.31, I1), the control unit 2 gives a command to turn all the wheels 3 to a vertical position. In this case, the electric drive of the chain drive 4 is turned on, which, with the help of the chain drive 5, rotates all eight half shafts 6, at the ends of which the wheels 3 are fixed. At the moment when the wheels 3 are turned into a vertical position, the rod 7 placed on the axis 6 abuts against the stop vertical stroke 8 and the limit switch 9 is activated, while the electric motor of the chain drive 4 is turned off, the wheels 3 are installed in a vertical position.

To further move along the trajectory B1, D1, 31 in the vertical direction along the vertical guides 10, the control unit 2 includes a wheel drive motor 11, which transmit a torque to the wheels 3 through a gearbox 12, half shafts 32, a chain gear 33 and wheel gears 34; the transport device 1 first moves to position D1 and then, without stopping, to position 31. In position 31, the control unit disables the wheel drive motor 11 and the transport device 1 stops. The exact stop of the transport device 1 at position 31 (or any other positions) is fixed using the mark 13 and the position sensor 14.

After stopping the transportation device 1, the control unit 2 gives a command to fix the position of the transportation device on the horizontal guides 15 using the synchronization device position of the transportation device. To do this, the stops 16 using the feed drive stop 17 are in the grooves 18, the position of the transport device 1 is rigidly fixed. Then, the control unit 2 gives a command to turn the wheels 3 in a horizontal position. In this case, the electric drive of the chain drive 4 is turned on. At the moment when the wheels 3 are turned 90 degrees to the horizontal position, the rod 7 rests against the travel stop 19 and the limit switch 20 is activated, the electric drive of the chain drive 4 is turned off. After the completion of the rotation of the wheels 3 in a horizontal position at the command of the control unit 2, the stops 16 exit the grooves 18.

To further move from position 31 to position I1, the control unit 2 includes a wheel drive motor 11; there is a horizontal movement of the transportation device 1 along the horizontal guides 15 from position 31 to position I1. Having moved to position I1, the control unit 2 of the transportation device 1 turns off the electric motor 11 and the transportation device 1 stops, followed by a command to fix the position of the transportation device 1 on the guides 15 using the mechanism for synchronizing the position of the trolley.

If it is necessary to move the transportation device 1 from position 31 to position, for example, 3 using the in-depth movement system along trajectory 31, Ж1, Ж, 3 (the transportation device 1 to position Ж1 can only go from position 31 and vice versa - from position Ж1 can go only at 31; also apply to positions G and 3) control unit 2 gives a command to translate all wheels 3 into a horizontal position. Then, the transportation device 1 is moved to the node of deep movement, in position G1 (figure 1). After moving in G1, the wheels 3 move to a vertical position, the transportation device 1 along the vertical guides of the deep-moving unit (24, 25, 28, 29) lowers down onto the guides for moving deep into 23 (Fig. 2). This position is detected by a position sensor for moving to a depth of 30 using a position mark for moving to a depth of 21.

For further movement, the right-hand side 25 and left-24 rotating part with vertical and horizontal guides of the deep-moving unit of row 1 is rotated by the rotation drive of the deep-moving guides 31, driven by, for example, an electric motor or a hydraulic piston, 90 to the right and left degrees so as not to interfere with the passage of the transportation device 1 along the guides to a depth of 23. It also happens with the guides 26 and 27 (figure 3).

The transportation device 1 begins to move along the rails 23 in depth, to row 2. At the same time, only the lower row of wheels 3 that travel along the rails 23 (Fig. 4) are used for movement. To move along the guides 23, the gearbox 12 of the engine 11 must switch the direction of rotation of the axle shafts 32, which transmits torque from the gearbox 12 to the wheels 3. If the axis 32 is solid, then when moving in depth, the lower wheels at opposite ends of the carriage will rotate in different directions and the trolley does not move. Therefore, the axis coming from the gearbox 12 is made of two axles and when moving in depth, the gearbox 12 rotates one axis 32 in one direction, the other in the opposite direction.

The transportation device 1 moves in a row 2 (figure 5)

For further movement, the parts 24, 25, 26 and 27 stand in their original position (Fig.6). The transportation device moves vertically to position G. Then, turning the wheels in a horizontal position, moves to position 3.

To brake the transportation device 1, a reverse of the electric motor of the drive of the wheels 11 is used, while the released energy is supplied to the current source 22.

The control unit, all electric motors and other systems are powered by a current source 22.

The calculated power of the electric motor 11 for moving goods weighing (including the mass of the trolley 1) up to 3000 kg does not exceed 8 kW.
