The invention discloses a control device (40) for synchronizing a luffing mechanism (20) with a lifting mechanism (30) of a mast. The control device (40) comprises receiving equipment for receiving a reeling-off signal and a synchronizing signal; processing equipment for generating a control signal for controlling the reeling-off speed of the luffing mechanism (20) of the mast according to the reeling-off signal, and generating a startup signal for starting up the lifting mechanism (30) to execute a lifting action under the condition that the reeling-off signal and the synchronizing signal are simultaneously received; and output equipment for outputting the control signal and the startup signal to the luffing mechanism (20) and the lifting mechanism (30) of the mast respectively. The control device (40) can start up the lifting mechanism (30) while operating the luffing mechanism (20) of the mast, so as to make the lifting mechanism (30) and the luffing mechanism (20) always synchronous to avoid wire rope entanglement.
Description
technical field [0001] The invention relates to a control device, a system and a construction machine for synchronously operating a mast luffing mechanism and a mast lifting mechanism. Background technique [0002] At present, masts are widely used in the field of lifting. For example, when a crawler crane product is transferred or assembled for the first time, it is necessary to place the mast from a horizontal position to a position at a certain angle to the horizontal plane. figure 1 A schematic diagram of a mast installed in the prior art is shown. Such as figure 1 As shown, the need to figure 1 The mast 10 shown in is mounted from a horizontal position (ie, a 180° position) to a position of approximately 60°. The entire installation process is completed through the cooperation of the luffing mechanism 20 and the jacking mechanism 30 . The luffing mechanism 20 may generally include a motor that drives the drum to rotate and a wire rope 22 wound on the drum, and the ...
