Abstract

The invention relates to a rescue accessory with an expansion supporting function and a hydraulic control system thereof, and belongs to the technical field of engineering machinery rescue equipment.The rescue accessory consists of a mounting base part (1), a seam lifting expansion system (2), a jacking protection system (3), a conveying system (4) and a hydraulic control system (21), wherein theseam lifting expansion system (2) is driven by two seam lifting expansion power hydraulic cylinders (9) at the left and right, and the extension of a compression rod completes seam-lifting expansionaction on ruins; the jacking protection system (3) is driven by four jacking hydraulic cylinders (11) to complete supporting protection action; and the conveying system (4) extends out through the compression rod of a conveying hydraulic cylinder (14) to realize the conveying of the jacking protection system. The whole rescue accessory is powered by hydraulic pressure, has multiple functions, is simple in structure and convenient to operate, can be directly mounted at the front end of an existing common construction machine, and is used for disaster rescue, and the rescue efficiency is greatlyimproved.

Description

technical field [0001] The invention relates to a rescue attachment with an expansion support function, a hydraulic control system and an implementation method thereof, which belong to the field of construction machinery rescue equipment, and specifically relate to mechanical design, mechanical principles, and hydraulic transmission control technology. Background technique [0002] In the rescue process of natural disasters, construction machinery plays an important role in rescuing lives and properties with good operating performance, flexible rescue functions, and fast and efficient rescue efficiency. However, the original intention of many construction machinery designs is not for emergency rescue, so in practice, the existing attachments have also exposed problems such as single function, low efficiency, and insufficient safety performance. There is a major threat to the safety of personnel. Therefore, it is necessary to design a special rescue tool with the function of...
