Abstract

The invention provides a four-cylinder synchronous translation mechanism and its control method, which are used for horizontal translation control of loads in a double winch system; the four-cylinder synchronous translation mechanism includes a telescopic mechanism and a control mechanism; The hoisting system is connected with the hoisting mechanism of the double hoisting system in transmission; the control mechanism is connected with the telescopic mechanism in communication, and is used to control the telescopic mechanism to perform telescopic operation according to the user's control instructions, and the telescopic mechanism is used to push the hoisting mechanism to drive the load under the control of the control mechanism Pan in the horizontal direction. The present invention realizes the macro synchronization of the oil cylinder by mapping the ratio of the area of ​​the rod chamber to the rodless chamber of the oil cylinder as the input amount of the handle for manipulating the movement of the oil cylinder, and realizes fine-tuning of the synchronization performance by performing PID control by comparing the dynamic movement distance. The problem of lateral movement adjustment in the horizontal direction of the load is solved, and four-point synchronous translation is realized.

Description

technical field [0001] The invention relates to the technical field of winch system control, in particular to a four-cylinder synchronous translation mechanism and a control method thereof. Background technique [0002] In the double winch system, when the load is lifted or lowered by the left and right hooks, it is often necessary to translate the load left and right in the horizontal direction so that the load can be aligned to a precise position. [0003] At present, the movement of the load in the horizontal direction is realized by moving the whole vehicle; however, it takes a lot of time to move the whole vehicle, and the accuracy of load translation is difficult to guarantee. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a four-cylinder synchronous translation mechanism and its control method to solve the problem of load horizontal movement adjustment in the double winch system and realize four-point syn...
