Hydrocylinder-type anti-rolling system used for crane

Abstract

The invention discloses a hydrocylinder-type anti-rolling system used for a crane, which is structurally characterized by comprising a hanger, a hoisting drum and a trolley frame, wherein the hoisting drum is connected with the hanger after passing through a fixed pulley by a hoisting steel wire rope and is connected with an anti-rolling drum arranged on the trolley frame by a chain transmission device; the anti-rolling drum is connected with a fixed pulley set arranged on the trolley frame by an anti-rolling steel wire rope (5. a. b. c. d); then, the anti-rolling steel wire rope (5. a. b. c. d) is crosswise connected with the fixed pulley set arranged on the hanger after passing through the fixed pulley set; finally, the anti-rolling steel wire rope (5. a. b. c. d) is connected with a piston rod of an anti-rolling oil cylinder (2. A. B. C. D) after passing through the fixed pulley; and a hydraulic power unit is connected with the anti-rolling oil cylinder (2. A. B. C. D) by an oil channel pipe. The invention has the advantages that the system has simple structure, lower manufacture cost, easy realization, good anti-rolling effect and the like; the hoisting swing angle is attenuated according to an exponential form; when the structural parameters of the system are determined, the hydrocylinder-type anti-rolling system has a structural parameter matching hoisting weight with the best anti-rolling effect (the shortest attenuation time).

Description

Technical field: [0001] The invention relates to a hydraulic oil cylinder type anti-sway system for cranes, which has the characteristics of simple structure, low manufacturing cost, easy realization and good anti-sway effect, and is the most widely used anti-sway system in container cranes at present. Background technique: [0002] Whether it is active anti-sway for hoisting or passive anti-sway for hoisting, the types of anti-sway and anti-sway control systems (devices) generally include mechanical type, hydraulic cylinder type, wire rope type, mechanical electronic type and intelligent electronic type. Mechanical anti-sway can be summarized into two forms: one is to consume the energy of swing by mechanical means to achieve the ultimate purpose of eliminating the swing of the hoisting weight, and most mechanical anti-sway devices are based on this principle; the other is to increase the rigidity of the suspension system Suppression of sway. Mechanical anti-sway devices g...

AI Technical Summary

Problems solved by technology

Mechanical anti-sway devices generally have complex mechanisms, poor reliability, and heavy maintenance workload. The anti-sway effect is not ideal when the hoisting wire rope is long. slower, unresponsive
