Control system and control method of safe hoisting of front hoist

Abstract

The invention discloses a control system and a control method of safe hoisting of a front hoist. The system comprises an identification module, a measurement module, a safe hoisting module and an anti-tipping module, wherein the identification module is used for collecting images through a camera, identifying the images and judging whether the condition is a condition in which a container is unloaded from a train flatcar or not; the measurement module is used for measuring the length of a telescopic cylinder and the length of a pitching oil cylinder in real time through laser distance measurement sensors; four rotary locking type tension and pressure sensors on a hoisting appliance are used for measuring hoisting force of the container in real time; the safe hoisting module is used for judging a relative position between the container and a flatcar floor in the hoisting process according to collected data of the rotary locking type tension and pressure sensors; a hoisting speed and a hoisting direction of the hoisting appliance are controlled on the basis of data collected by the measurement module, so that a bottom corner part of the container can smoothly disengage from an F-TR lock on the flatcar, and the damage and the derailment of the flatcar are avoided; the anti-tipping module is used for considering the actual gravity center position of the container; compared with theexisting anti-tipping system of the front hoist, the anti-tipping module is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of front stacker control systems, in particular to a hoisting control system and control method for loading and unloading containers from train flat cars. Background technique [0002] Reach stackers are commonly used in railway freight yards for container loading, unloading and stacking operations. The existing reach stacker has the functions of vertical lifting and anti-tipping, but when unloading the container from the flat car, there may be a phenomenon that the bottom corner of the box body is not decoupled from the F-TR lock of the flat car, and even the flat car is hoisted. The Chinese utility model whose patent number is CN201520132108.6 discloses a safety lifting control system. A proximity switch is installed between the upper and lower frames of the spreader. The function of preventing false lifting of train F-TR lock. However, this patented technology does not detect and control the lifting pro...
