CONTROLLER OF THREE AXIAL OVERHEAD CRANE

摘要

Purpose: a controller of three axial gantry cranes is arranged to prevent a kind of shake of the material of the transmission generated during mobile gantry crane and rapidly moves gantry crane in the position needed for one. Construction: a controller of three axial gantry cranes removes controller comprising speed servo typewriting, is used to prevent the shake of the first thermal compensation signal of a reference position input signal of output one purlin of compensation or a trolley and is operated according to a control and regulation of the removing of a control and regulation table by the inclusion of removing. One first control signal of the first adjustment equipment of position (107) and an initial velocity servo type controller output speed controls the speed positioning purlin of each engine for driving to or the trolley in a target is equipped with according to the placement of the control signal of position. By the output signal that an a kind of reference-input signal of the height of the material from transmission adjusts height export the second adjustment equipment of a control signal of height by comprising. For a second speed servo type controller of the position of the second control signal of output speed, control signal of the material of transmission to an object height according to height is reached to control the speed of driving motor, and drive engine to a second speed servomechanism installation (109) of the speed of driving motor, with a Z-direction of the material of transmission follow the second control signal of speed by comprising.
