The technical improvement of the utility model lies in: a tilt angle sensor 7 is arranged on one section of arm 6 through a bolt; the tilt angle sensor 7 is respectively connected and communicated with the arm support controller 11 through signal lines. The tilt angle sensor 7 can measure the angle of the first arm 6 after being unfolded under the driving of the first arm lifting hydraulic cylinder 15 (i.e. the angle of the arm support formed by the first arm 6 and the second arm 4). As shown in fig. 8 and 9, the turntable angle encoder 8 is fixed on the disk portion 9-1 of the turntable 9 by bolts, the driven gear 33 is fixedly connected with the rotor of the turntable angle encoder 8, the driven gear 33 is meshed with the teeth on the outer ring 31-1 of the rotation support 31, when the turntable 9 rotates, the disk portion 9-1 rotates, and the rotor of the turntable angle encoder 8 rotates due to the meshing of the driven gear 33 and the outer ring 31-1, and the turntable angle encoder 8 performs detection work.

A boom one-key centering switch is arranged on the operation console 10, and is used for controlling boom centering, and is electrically connected with the boom controller 11. When the deicing vehicle is at the initial position shown in fig. 2 and 3, the arm support controller 11 respectively sets the angle value detected by the tilt sensor 7 and the angle value detected by the rotary table angle encoder 8 as 0 point; then, the deicing vehicle carries out deicing operation on the airplane, as shown in fig. 4 and 5, a worker operates in the operation cabin 1 to enable the high-altitude operation device 300 to act, so that the operation cabin 1 is close to the position of the airplane needing deicing, and different deicing positions determine the rotation angle of the rotary table 9, the stroke of the one-section arm lifting hydraulic cylinder 15, the stroke of the two-section arm telescopic hydraulic cylinder and the stroke of the folding arm hydraulic cylinder 17; therefore, the rotation angle of the turn table 9, the stroke of the one-arm lift hydraulic cylinder 15, the stroke of the two-arm telescopic hydraulic cylinder, and the stroke of the folding arm hydraulic cylinder 17 during the deicing operation are not fixed and random. When the boom return is needed after the deicing operation of the deicing vehicle is finished (at this time, the boom is in the unfolded state shown in fig. 5, and the turntable 9 is in the non-neutral state), the boom one-key return switch is turned on, the boom one-key return switch sends a signal to the boom controller 11, the tilt sensor 7 detects the angle value C of the position of the one-joint boom 6 in real time, the turntable angle encoder detects the angle value D of the position of the turntable 9 in real time, data C, D is sent to the boom controller 11, when the angle value C detected by the tilt sensor 7 is greater than a set threshold value (for example, the threshold value is 30 degrees, and the angle of the boom is 30 degrees shown in fig. 9), the boom controller 11 sends a control instruction to the boom control valve group 13 to control the hydraulic motor 14 to rotate reversely, the boom controller 11 compares the data D detected in real time with a preset value 0 until the angle value D detected by the turntable angle encoder is equal to 0, the boom controller 11 stops sending a control instruction to the boom control valve group 13 to stop the operation of the turntable hydraulic motor 14, and at this time, the boom return to the initial position shown in fig. 3, and the boom return process is finished. For signal judgment, when the condition of D =0 is satisfied, the control command signal sent by the boom controller 11 to the boom control valve group 13 is cut off.

If the angle value C detected by the tilt sensor 7 is not greater than the set threshold, the boom controller 11 will not send a control command to the boom control valve group 13 to control the turntable hydraulic motor 14 to rotate in the reverse direction.

Therefore, the operation of returning the arm support to the initial neutral position is very convenient, the arm support is quick to return to the neutral position, the time is short, and the arm support can be accurately in place. Greatly reducing the labor intensity of operators. The automatic centering can avoid the misoperation of the operator. The accident that the arm support touches objects around a cab or an ice removing vehicle in the process of returning when the angle of the arm support is too low is prevented.

It should be noted that the tilt sensor 7 may specifically adopt an INX360D-F99-I2E2-V15 model tilt sensor of the company beckfurter.
