The structural design and safety assurance technology of intelligent mechanical automated parking garages are the cornerstone of ensuring stable and reliable operation and safeguarding vehicles and personnel.
In terms of structural design, intelligent mechanical automated parking garages have unique design concepts based on different types and functional requirements. Taking the common lifting and transverse moving type of intelligent mechanical automated parking garage as an example, its overall structure consists of main components such as a steel structure frame, vehicle carrier plates, lifts, and transverse moving devices. The steel structure frame is the skeleton of the garage, bearing the entire weight of the garage and the load of the vehicles. When designing the steel structure frame, engineers use mechanics principles and finite element analysis methods to accurately calculate the stress conditions of the frame under various operating conditions. For example, considering factors such as the weight distribution of vehicles on different floors, seismic forces, and wind forces, the cross-sectional shape, size, and material strength grade of components such as columns and beams are reasonably determined. Columns usually use rectangular or circular steel pipes with larger cross-sections to provide sufficient vertical load-bearing capacity; beams select appropriate I-beams or H-beams according to the span and stress conditions to ensure that the load can be effectively transferred in the horizontal direction. At the same time, in order to improve the overall stability of the frame, bracing and corner bracing are also set up in the structural design to form a stable spatial structural system.
As the component that carries the vehicles, the design of the vehicle carrier plate must meet the parking requirements of the vehicles while having sufficient strength and stiffness. The vehicle carrier plate is generally made of welded steel plates, and the surface is provided with anti-skid textures or rubber pads to prevent vehicles from sliding during parking and handling. At the connection points between the vehicle carrier plate and the lift and transverse moving device, special connection structures and high-strength bolts are used to ensure reliable connection and to withstand the impact force during the lifting and transverse movement of the vehicles. The lift is the key equipment for realizing the vertical lifting of vehicles, and its structural design focuses on improving stability and safety. The lift car uses a closed structure, and protective railings are set up on all sides to prevent vehicles from accidentally falling during lifting. The lift track uses high-precision guide rails, which cooperate with the guide shoes on the lift car to ensure the verticality and stability of the lift car during the lifting process. The transmission system uses steel wire ropes or chain drives. The selection of steel wire ropes or chains must meet the requirements of strength and fatigue life, and multiple safety protection devices are equipped, such as broken rope protection devices and overload protection devices. The transverse moving device is responsible for the horizontal movement of vehicles, usually consisting of components such as motors, gears, racks or sprockets, and chains. The design of the transverse moving device must ensure that the vehicles are accurately positioned and move smoothly during transverse movement, and limit switches and buffer devices are set to prevent vehicles from colliding with other objects during transverse movement.
In terms of safety assurance technology, intelligent mechanical automated parking garages are equipped with a complete safety protection system. In addition to the safety protection devices mentioned above on the lifts and vehicle carrier plates, the garage is also equipped with anti-fall devices, anti-collision devices, and fire protection systems. Anti-fall devices are installed on the vehicle carrier plates or lift cars. When a steel wire rope breaks or other accidents cause the vehicle carrier plate or lift car to fall, the anti-fall device can quickly start and, through mechanical braking or buffer structures, suspend the vehicle carrier plate or lift car in the air to avoid vehicles from directly falling to the ground and causing serious losses. Anti-collision devices are distributed at various passages and entrances and exits of parking spaces in the garage. When vehicles deviate from the track or are about to collide during driving or handling, the anti-collision device will automatically trigger and, through buffer materials or mechanical blocking structures, reduce the impact force of the collision to protect the safety of vehicles and equipment. The fire protection system is an important part of the safety assurance of intelligent mechanical automated parking garages. The garage is equipped with fire detectors, automatic sprinkler fire extinguishing systems, fire extinguishers, and other fire protection facilities. Fire detectors can promptly discover fire hazards and issue alarms. The automatic sprinkler fire extinguishing system can automatically start and spray water to extinguish fires when a fire occurs. Fire extinguishers allow management personnel and vehicle owners to fight initial fires. In addition, emergency evacuation passages and signs are set up in the garage to ensure that personnel and vehicles can evacuate quickly and safely in the event of a fire or other emergency. Through carefully designed structures and complete safety assurance technology, intelligent mechanical automated parking garages provide safe and reliable solutions for urban parking.
