Description

Technical Field

[0001] The utility model belongs to the technical field of earthquake rescue, and in particular relates to an earthquake rescue auxiliary device. Background Art

[0002] During earthquake rescue operations, when trapped people are buried under structures, support and shoring are sometimes necessary within a small space to expand the rescue area. Commonly used support and shoring equipment includes air cushions and jacks. Air cushions are inflated at the disaster site, powered by high-pressure gas cylinders or foot-operated air pumps, to lift or squeeze obstacles and rescue trapped people.

[0003] Because the building structure that needs to be supported is damaged and the structure is unstable, the rescuers are prohibited from putting their hands into the structure that needs to be supported when the lifting cushion is in use to avoid injury. Therefore, it is necessary to use an auxiliary device to put the lifting cushion into the structure that needs to be supported. In the prior art, CN220558441U discloses a multifunctional auxiliary tool for earthquake rescue support, including a first connecting rod, the bottom end of which is fixedly connected to an L-shaped push plate. The lifting cushion can be pushed to the correct position through the first connecting rod and the L-shaped push plate fixedly connected to the bottom end of the first connecting rod. However, it was found during use that due to the complex spatial structure in the narrow house structure, accompanied by interference from obstacles such as gravel and baffles, its technical solution is only to achieve the placement of the lifting cushion by lifting. During the placement process, the lifting cushion is easily displaced or even falls off from the L-shaped push plate due to collision with obstacles, and it is inconvenient to recycle the lifting cushion after use, affecting the rescue efficiency.

[0004] Based on the deficiencies in the prior art, the utility model discloses an earthquake rescue auxiliary device, which provides a clamping plate for clamping the edge of a lifting air cushion on the basis of an existing L-shaped push plate, and provides a transmission rod on the inner ring of a connecting pipe to control the clamping and release of the lifting air cushion by the clamping plate, thereby improving the supporting stability of the support plate on the lifting air cushion, and facilitating the removal of the lifting air cushion after use, thereby improving the rescue efficiency.
