4. The device for detecting verticality of a boom tower crane according to claim 1, wherein: A positioning groove is respectively provided at the lower part of each driven gear (701), and a limiting wheel (708) is provided in the inner cavity of the positioning groove. The other end of the limiting wheel (708) is movably connected to a support rod (709), and the other end of each support rod (709) is fixedly connected to the inner wall of the rotating disk (62), and the positioning groove and the limiting wheel (708) cooperate with each other.

5. The device for detecting verticality of a boom tower crane according to claim 3, wherein: The total station control box (3) includes a controller inside, and the encoder (69), the Hall sensor (602) and the electromagnetic clutch (75) are electrically connected to the controller respectively.

6. The device for detecting verticality of a boom tower crane according to claim 5, characterized in that: The following steps are also included: Step S1: Start the device, initialize the total station control box (3) and the total station body (5) through the controller, and detect the connection status of each component; Step S2: adjusting the levelness and stability of the device by adjusting the base (1) and the support assembly (2) to ensure that the support feet (23) are firmly in contact with the ground; Step S3: The motor (68) is started by the controller to drive the driving shaft (67) to rotate, thereby driving the rotating disk (62) to rotate through the bevel gear A (65) and the bevel gear B (66); Step S4: The encoder (69) monitors the rotation angle of the rotating disk (62) in real time and transmits the data to the controller; Step S5: When the Hall sensor (602) detects the signal of the magnet (601), the controller determines the eyepiece switching position and controls the motor (68) to stop rotating; Step S6: The controller starts the electromagnetic clutch (75), which drives the connecting rod (74) and the transmission rod (76) to move through the synchronous wheel A (71), the synchronous belt (72) and the synchronous wheel B (73); Step S7: The transmission rod (76) drives the clamping block (703) to move by driving the flat gear (77), the connecting gear (78) and the driven gear (701), and positions the target eyepiece (flat-field eyepiece (706) or the curved tube eyepiece (707)) to the working position; Step S8: After the controller confirms that the eyepiece switching is completed, it starts the total station body (5) to perform the verticality detection of the tower body; Step S9: After the detection is completed, the controller automatically switches the eyepiece or turns off the device according to a preset program.
