Diamond bead hydraulic rope saw for firefighting emergency rescue and working method thereof

Abstract

The invention relates to a diamond bead hydraulic rope saw for firefighting emergency rescue. The diamond bead hydraulic rope saw comprises a movable rack, a feeding system, a driving system and a bead rope group, wherein the movable rack comprises angle braces, fixed blocks, a truss, a rack guide rail and a rope storage wheel, wherein the angle braces, the truss and the rope storage wheel are connected with fastening bolts by the fixed blocks; the rack guide rail is embedded and fixed on the truss; the feeding system comprises a base, a handle, a walking motor, a main motor, a guide wheel and a driving wheel; the base is mounted on the truss and is connected with a truss sliding pair; the base is used for carrying the walking handle, the walking motor, the main motor, the main guide wheel and the main driving wheel; the driving system comprises a hydraulic hose, a mobile hydraulic power station and a control valve box; the mobile hydraulic power station is used for connecting two low-power mobile hydraulic pumps into the control valve box in parallel by the hydraulic hose; the control valve box is used for adjusting the flow magnitude of the hydraulic hose of the output end through a valve group so as to drive the main motor and the walking motor respectively; the bead rope group adopts a dry cutting type brazing bead threading rope as a cutting and breaking tool and does not need a cooling device.

Description

technical field [0001] The invention relates to a diamond-beaded hydraulic wire saw for fire emergency rescue, and belongs to the technical field of fire emergency rescue wire saws. Background technique [0002] In recent years, with the gradual deterioration of the environment and climate and the rapid development of urbanization and industrialization, natural geological disasters such as earthquakes and mudslides in my country have entered a period of high incidence, and production safety accidents such as traffic accidents and building collapses have also occurred frequently. Production and life and the safety of life and property constitute a huge impact. For example: On May 12, 2008, a magnitude 8.0 earthquake occurred in Wenchuan County, Sichuan Province. The direct economic loss reached trillions of yuan, and the number of victims exceeded 80,000. On August 7, 2010, a catastrophic torrent and mudslide disaster occurred in Zhouqu County, Gannan Tibetan Autonomous Prefe...

AI Technical Summary

Problems solved by technology

For the demolition of concrete components and rocks, the existing rescue equipment of the fire brigade mainly includes diamond chain saws, circular saws, and breaking picks. Due to the small cutting radius, heavy weight, and large volume, the operation is relatively cumbersome It is too suitable for long-term demolition and rescue needs in small spaces, and cannot meet the demolition and movement work of large-volume concrete or stones
