The invention relates to transport engineering and concerns prompt delivery of three-dimensional structures. The objective of the invention is more reliable operation of a device for vertical movement of a three-dimensional structure and, by means of the device, speeding up and facilitation of transportation of three-dimensional structures by vehicles. The device (Fig. 1) for vertical movement of a transported three-dimensional structure (2) installed on a vehicle (1) equipped with a pneumatic system (3) comprises rotatable brackets (9) mountable on the transported three-dimensional structure (2) and provided with support pads (21), power cylinders (15) with rods (14) and spring-loaded pistons (16). The rotatable brackets (9) are provided with guides (10) accommodating movable hollow bars (11) fixed in respect of the guides (10) by clamps (12) linked to rods (14) of the power cylinders (15), the rods being fixed on the guides (10), wherein the support pads (21) are implemented as chambers accommodating sealed movable partitions (22) provided with hollow rods, and power cylinders (15) and the top ends of the hollow bars (11) can communicate, through two-position pneumatic valves (26), with the pneumatic system (3) of the vehicle (1), the hollow rods and the bottom ends of the hollow bars (11) being provided with elements for sealed connection thereof. Versatility and quickness of lowering and lifting of three-dimensional structures (2) allow significant reduction of the time required for assembly from them lodgements for hospitals, collecting centres for forcibly displaced persons, refugees, people suffered from natural disasters or other emergencies as well as power plants, automatic telephone stations, warehouses, workshops, garages, amenity rooms, etc. |
