Heavy-load large-distance coniform spiral-expanding rescuing equipment

Abstract

The invention relates to heavy-load large-distance coniform spiral-expanding rescuing equipment. The equipment has the technical key point that a screw thread shaft is clamped at the middle of the existing expander pincers and pincers mouths, the front end of the screw thread shaft is machined to be a coniform spiral cutting head, the back end of the screw thread shaft is connected with a moment input device, the screw thread shaft with the screw thread in the equipment body is sleeved with a castellated movable clutch and a pushing clutch, the pushing clutch is fixedly connected with a top rod slide block, the top rod slide block is also articulated with the back parts of the left pincer body and the right pincer body through a connecting board, the top of the castellated movable clutch is provided with a lug boss, the lug boss is positioned in an L-shaped sliding groove at the middle of the equipment body, and the left pincers mouth and the right pincers mouth are respectively articulated with a left expanding distance-increasing mechanism and a right expanding distance-increasing mechanism. The heavy-load large-distance coniform spiral-expanding rescuing equipment solves the defect that the existing expander can not extend to perform the expansion under the condition that a gap is narrow or a gap is unavailable, enlarges the expansion distance, and further expands a rescuing passageway.

Description

technical field [0001] The invention belongs to the technical field of rescue mechanical equipment, and in particular relates to a heavy-duty large-distance conical spiral expansion rescue equipment. Background technique [0002] With the frequent occurrence of geological disasters such as earthquakes, traffic accidents and industrial accidents, the country pays more and more attention to the rescue work of sudden disasters. Based on the idea that people's lives and property are above all else, as long as there is hope of rescue, rescue Officers and soldiers will spare no effort to do everything possible to rescue the injured and trapped people. In rescue work, time is life, and rescue equipment is also an indispensable weapon in their hands, and it is playing an increasingly important role in rescue work. Therefore, for Rescue equipment also puts forward higher and higher requirements. For example, currently widely used rescue dilators, because the jaws are stressed during...

AI Technical Summary

Problems solved by technology

For example, currently widely used rescue dilators, because the jaws are stressed during expansion, the jaw structure must have a certain thickness. For example, when the gap is less than 5 mm or there is no gap, it cannot be extended. Therefore, other methods or tools must be used to properly expand the narrow gap before the rescue can be performed, which delays the best time for rescue. Time affects the rescue effect
