AI Technical Summary

Technical Problem

Existing technologies lack efficient and safe remote operation solutions for the rescue of trackless loaders stranded underground due to mechanical failure, electrical system malfunction, or geological disasters. In particular, the precise alignment of the braking lock and hook components poses a challenge, requiring rescue personnel to enter dangerous areas and creating safety risks.

Method used

By installing a wireless remote-controlled electric hydraulic pump and solenoid valve in the hydraulic braking system of the loader, and equipping it with an independent backup battery, combined with a wireless image transmission system and camera, remote release of brake lock and precise hooking can be achieved, and rescue operations can be completed through a wireless remote control and handheld display screen.

Benefits of technology

It has achieved unmanned, end-to-end rescue operations, avoiding the need for rescuers to enter dangerous areas, ensuring personal safety, and improving rescue efficiency and safety.

Abstract

This invention discloses a method for rescuing a two-cubic-meter loader stranded in an open area, belonging to the technical field of rescue methods. The invention includes the following steps: S1, modifying the malfunctioning loader: adding an electric hydraulic pump controlled by a wireless remote controller and a normally open two-position three-way solenoid valve to its hydraulic braking system, and equipping it with an independent backup battery to power the electric hydraulic pump and solenoid valve; simultaneously, fixing a trailer hook at the rear of the loader. This invention solves the problem of remotely releasing the brakes of a malfunctioning loader when it is in a brake-locked state by adding an independently powered remote-controlled hydraulic release system. Combined with wireless image transmission visual assistance technology, it achieves remote and precise alignment and attachment of the trailer hook, completing the unmanned operation of key rescue operations; it constructs a complete remote rescue method from remote brake release, visual-assisted hook attachment to remote towing, allowing rescue personnel to remain in the danger zone throughout the process, fundamentally ensuring personal safety.
