Embodiment Construction
[0039] The present invention is described in further detail below in conjunction with accompanying drawing:
[0040] see Figure 1-3 , this one-button deployment / folding device for knuckle boom cranes includes an operating device 1 and a data acquisition device installed on the crane body, a processor module 3 and an execution device 4; the operating device 1 and the data acquisition device are passed through The input circuit in the processor module 3 is connected to the processor module; the processor module 3 is connected to the execution device 4 through its internal output circuit.
[0041] The operating device 1 includes a switch 2 for switching between the normal operation mode and the one-key operation mode of the crane, and a joystick 6 for controlling the extension / retraction of each oil cylinder on the crane. The setting of the toggle switch is to prevent misoperation caused by confusion between one-button operation and normal operation. instruction, and pull down...

The invention discloses a device and a method for unfolding and withdrawing a folding-arm crane by one-key operation. The device comprises the crane, an operating device, a data acquiring device, a processor module and an executive device, wherein the data acquiring device is installed on a machine body of the crane; the operating device and the data acquiring device are connected with the processor module through an input circuit in the processor module; and the processor module is connected with the executive device through an output circuit in the processor module. According to the device and the method, the data acquiring device is arranged on the traditional folding-arm crane and transmits acquired information to the processor module installed on the crane, and the processor module performs analytical judgment on the acquired information and then sends a command to control the executive device according to the acquired information, so that the crane in a free state can automatically withdraw and be switched into a driving state by one-key operation, and the crane can unfold in an optimal route through a program; and therefore, the efficiency of unfolding and withdrawing and automation level are improved, and the working efficiency is improved.
Description
technical field [0001] The invention belongs to the field of cranes, and relates to a crane unfolding / folding device, in particular to a one-button unfolding / folding device and method for a knuckle-arm type crane. Background technique [0002] During the unfolding process of the folding arm truck-mounted crane, the outer arm is generally folded first, and then the inner arm is unfolded. When the inner arm is unfolded to a certain angle, the outer arm is started to unfold. During the unfolding process of the outer arm, if the outer arm and the turntable etc. Interference, it is necessary to further expand the inner arm to the appropriate position, and then continue to expand the outer arm. Since it is difficult to grasp the most appropriate deployment angle of the inner arm during the deployment process, it needs to be adjusted during the deployment process, which reduces the deployment efficiency. Contents of the invention [0003] The purpose of the present invention is ...
