Clamping shearing snatching and seam expanding integral rescue tool

Abstract

The invention discloses a clamping shearing snatching and seam expanding integral rescue tool, which comprises a clamping shearing holding snatching and seam expanding conversion device, a constant shearing force device, holding and snatching mechanisms of four pairs of four-connecting-rod mechanisms and a seam expanding device, wherein a deformation hydraulic cylinder of the clamping shearing holding snatching and seam expanding form conversion device and a slide block realize the mutual switching among the clamping shearing, holding snatching and seam expanding forms; the constant shearing force device provides uniform shearing force for the clamping and shearing process; the secondary collapse in the rescue process is prevented; a holding snatching hydraulic cylinder of the four-connecting-rod holding snatching mechanism controls the position of holding snatching claws to realize the shielding and the work of clamp shear blades, and is matched with the clamping shearing holding snatching and seam expanding conversion device to complete the holding and snatching operation. The four functions including the clamping, shearing, holding snatching and seam expanding are integrated into one tool; the structure is reasonable and creative; the operation is simple and convenient; the dealing with complicated rescue environment can be realized; the complicated residue operation can be fast completed; the rescue efficiency is improved.

Description

technical field [0001] The invention relates to a new type of rescue attachment integrating pliers, scissors, grasping and sewing, and belongs to the technical field of disaster emergency rescue. Background technique [0002] Sudden disasters such as earthquakes, building collapses, and large-scale urban explosions have caused huge damage to human society, and brought huge casualties and economic losses to the country and the people. The leaders of the party and the state pay close attention to public safety and emergency relief work, and have visited the front line many times to direct rescue, requesting to improve independent innovation capabilities, overcome major industrial accident prevention and rescue technologies, and develop emergency rescue equipment with independent intellectual property rights. However, at present, rescue attachments generally only have a single rescue function. In the face of complex rescue environments during rescue operations, it is often nece...
