Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a lifting platform for fire-fighting installation. Background Art

[0002] Firefighting is the elimination of hidden dangers and the prevention of disasters. It is a general term for preventing and solving man-made, natural and accidental disasters encountered by people in the process of life, work and study. People generally install firefighting equipment to prevent various fires. Firefighting equipment refers to equipment used for fire extinguishing, fire prevention and fire accidents to ensure people's personal safety and prevent fire accidents. Some firefighting equipment needs to be placed at a high place through a lifting platform to maximize its effectiveness. The lifting platform used for fire safety can sometimes also be used for rescue.

[0003] Patent CN218708973U proposes a lifting platform for fire protection installation, which drives a bidirectional threaded rod to rotate through a motor, and then the bidirectional threaded rod drives two threaded sleeves to move, and at the same time the threaded sleeve drives the movable plate to move, and then the movable plate drives the positioning frame to move, and at the same time the positioning frame drives the connecting rod to perform circular motion through an axle pin, and then the connecting rod drives the limit frame to lift and lower, and at the same time the limit frame drives the slider to move upward, and then the slider drives the limit shell to lift and lower, and at the same time the limit shell drives the load-bearing plate to lift and lower, thereby completing the bidirectional simultaneous lifting in the process of lifting the platform, when the user needs to lift the platform on the lifting device to support it, at this time the first hydraulic rod group stretches to drive the connecting plate to move upward, and then the connecting plate drives the second hydraulic rod group to move upward, and at the same time the second hydraulic rod group supports the load-bearing plate, when the lifting height of the lifting device exceeds the stretching length of the first hydraulic rod group, at this time the second hydraulic rod group drives the load-bearing plate to lift and support it for the second time.

[0004] The above scheme is basically similar to the principle of the existing fire-fighting lifting platform, and can only achieve vertical lifting. In actual rescue operations, the rescue platform may be obstructed by the surrounding environment after it is raised, and the base position cannot be moved to a position where the rescue platform is close to the trapped persons. At this time, the rescue platform is also inconvenient to move, which will hinder the rescue mission. Utility Model Content
