[0034] The working process of the construction crane device is as follows:

[0035] (S1) The external remote control handle is transmitted to the PLC of the electric control cabinet 12 through the wireless transmission module, and the PLC outputs and controls the X-arm traction mechanism 9 in the X-arm structure 8, and the reel of the X-arm traction mechanism 9 pulls the Y-arm structure 14;

[0036] (S2) controlling the Y-arm traction mechanism 142 of the Y-arm structure 14, the drum of the Y-arm traction mechanism 142 pulls the crane 146, and controlling the lifting mechanism 146-4 in the crane 146;

[0037] (S3) The drum of the lifting mechanism 146-4 pulls the hook 146-7;

[0038] (S4) The PLC of the electric control cabinet 12 is connected to the X-arm traction mechanism 9 and the amplitude encoder, the Y-arm traction mechanism 142 and the amplitude encoder, the lifting mechanism 146-4 and the lifting height encoder, and the weight sensor 146-5; the PLC is provided with a wireless expansion module to receive the control signal of the remote control handle. The function of the three encoders is that the amplitude and height cannot exceed the limit position to ensure safety. The weight sensor 146-5 ensures that the weight of the hoisted object does not exceed the rated load of the construction crane.

[0039] The balance support rod 147 in this embodiment is on the Y-arm body 141, and uses a steel wire rope to ensure that the Y-arm can be balanced when the X-arm moves in the horizontal and vertical directions.

[0040] The standard section support frame in this embodiment is installed on both sides of the building, and the construction crane can be used for hoisting on the ground beside the building and on the roof of the building.

[0041] This embodiment should meet the requirements of hoisting working conditions. When the X and Y heights need to be increased, it is necessary to start lifting and adding sections at the bottom of the left and right support frames.

[0042] In this embodiment, the PLC of the electric control cabinet 12 is connected to the X-arm traction mechanism 9 and the amplitude encoder, the Y-arm traction mechanism 142 and the amplitude encoder, the lifting mechanism 146-4 and the lifting height encoder, and the weight sensor 146-5.

[0043] The PLC also has a wireless expansion module to receive control signals from a remote control handle (the remote control handle includes but is not limited to a remote control handle, and can also be an operating table on the top of a building or on the ground). The three encoders ensure that the amplitude and height cannot exceed the limit position to ensure safety. The weight sensor 146-5 ensures that the weight of the hoisted object does not exceed the rated load of the construction crane.
