Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] Such as figure 2 As shown, the recognition module collects images through the camera, performs image recognition, and judges whether it is the working condition of unloading containers on a train flat car; A twist-lock tension pressure sensor measures the lifting force of the container in real time; the safety lifting module is used to co...

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...
