Description

Technical Field

[0001] The utility model relates to the field of earthquake rescue, and particularly relates to an adjustable door frame for the passability test of a large earthquake rescue robot. Background Art

[0002] Large earthquake rescue robots (such as large earthquake rescue handling robots) play an irreplaceable role in the rescue inside dangerous buildings after earthquake disasters. They can perform tasks in dangerous environments, reduce casualties, and improve search and rescue efficiency. Large earthquake rescue robots (such as handling robots) are usually equipped with devices such as cameras, sensors, thermal imaging equipment, and deformable stretchers that can automatically carry wounded people onto the robots. They can even carry rescue operation equipment such as demolition and propping. Large earthquake rescue robots are used to search for trapped orthopedic survivors in collapsed buildings and ruins, clear obstacles in the rescue passage, reinforce the environment of the wounded, and transfer them to a safe place. They can also be used as medical support equipment in earthquake rescue. When survivors cannot be transferred, they can deliver medical supplies, drugs, first aid equipment, and food to the survivors.

[0003] The earthquake site is usually accompanied by building deformation and collapse, resulting in different sizes of the robot's access entrances. Therefore, in earthquake rescue tests, it is necessary to simulate entrances of various sizes that the robot passes through to test its passability. For large earthquake rescue robots, the passability test is extremely important, and the test results provide a scientific basis for their sustainable optimization and improvement.

[0004] When testing the passability of large earthquake rescue robots, frames of different sizes are usually built using wood or metal to simulate the entrances and exits. However, since multiple entrances and exits of different sizes need to be simulated, this means that multiple frames of different sizes must be built, and such a practice is very inconvenient and not popularizable.
