The manual operation adjusts the telescopic shaft (the part for connecting the jaw 61 to the positioning device 6) on the positioning device 6 to the gripping position and installs the safety pin. The system automatically records the numerical value of a position encoder, the numerical value of a lifting arm 4, the rotating angle of a rotating arm and the encoder parameters of a servo motor 32 connected with a telescopic shaft, the whole equipment automatically disassembles the middle section 9 of the corrugated pipe according to a set program after recording, all the shafts return to zero positions, and an alarm lamp prompts the completion of the disassembly operation of the middle section 9 of the corrugated pipe.
Bellows middle section 9 installation flow: the equipment is switched to a manual mode to transport and place the old corrugated pipe to a specified position, and then the middle section 9 of the new corrugated pipe is transported. Specifically, after the whole equipment completes self-checking operation, the lifting arm 4 is lifted by 30 degrees (according to the installation required angle of the corrugated pipe) and drives into the grabbing position in the axial direction of the corrugated pipe, the whole device is stopped after the preset laser automatic moment measuring device detects the set moment, and the lifting arm 4 is lowered to 0 position. The positions of the lifting arm 4 and the rotating arm are automatically adjusted, the clamping jaws 61 are aligned to the positioning bolts 91 of the bellows middle section 9, the four positioning bolts 91 of the bellows middle section 9 are clamped by the four clamping jaws 61 and fixed at the nuts, then the safety pins are inserted, the lifting arm 4 is lifted by 30 degrees, the new bellows middle section 9 is lifted to be 20cm away from the ground, and then the new bellows middle section 9 is transported to the position where the bellows middle section 9 is to be installed and is automatically positioned.
At the in-process of installing new bellows middle section 9, servo electric cylinder 31 promotes the bellows middle section 9 that lifting arm 4 will snatch and lifts to the mounting height, and rethread tilting mechanism 5 (usually be rotatory servo cylinder) is rotatory 9 to the installation angle in bellows middle section, carries out automatic positioning according to the positional information that the encoder detected, then compares the adjustment to the current position of dolly according to the positioning data when the dismantlement bellows of system record, and after the adjustment, whether the artifical mounted position of affirming is correct.
It should be noted that, for various reasons (for example, the sizes of the bellows middle sections 9 are slightly different), the installation position of each bellows middle section 9 has different differences, and the leveling degree of the ground where the whole equipment is parked is different, and the installation operation needs to be finely adjusted, and the height and angle adjustment can be performed by combining the servo electric cylinder 31, the turnover mechanism 5 and the automatic compensation mechanism 2; the position of the bolt hole of the positioning bolt 91 can be adjusted by extending and retracting the jack catch 61 and the telescopic shaft, so that the bellows middle section 9 slightly rotates along the axis of the bellows middle section 9 to align with the bolt hole, and the parallelism between the flange of the bellows middle section 9 and the upper end flange is finely adjusted by driving the slewing bearing through the preset servo motor 32. In addition, the maintenance worker can stand on the operation platform to quickly fasten the positioning bolts 91 through a preset hydraulic constant-torque full-automatic wrench.
