When the train is overhauled, the door leaf needs to be removed, and after the overhaul is finished and a new door is repaired, the door leaf needs to be installed on the train. When the door leaf assembling device works, two processes of assisting in disassembling the door leaf and assembling the door leaf can be completed.
When the door leaf is disassembled, the train door leaf to be overhauled needs to be disassembled and then placed into a specified position of a specified door leaf shelf. The specific process is as follows:
firstly, the whole machine is aligned to the door leaf to be removed, which is called as contraposition for short. Secondly, starting the electro-hydraulic integrated oil cylinder 33 to adjust the height of the lifting plate 4; starting the servo motor 52 to drive the ball screw mechanism 54 to move, and synchronously lifting the moving plate 55, the four-bar swing arm 66 and the universal suction cup 67 to preset positions; the gear motor 612 is activated to drive the big and small gears so that the four-bar swing arm 66 and the universal suction cup 67 are rotated 90 deg. to align the door leaf to be removed. And then the whole machine is pushed to enable each universal suction cup 67 to press the door leaf, and after the four suction cups 671 can completely contact the door leaf at the same time, two paths of vacuum pipelines of the suction cups are started to enable the suction cups to vacuumize, so that the pressure reaches the set pressure of-86 KPa.
After the pressure reaches a set value, the disassembly action is started, 1 person on the carriage unloads the screw, and the door leaf is separated from the door carrying frame positioning pin hole on the train. The wireless code disc is operated by 1 person on the workshop ground to respectively control the four-rod swing arm 66 and the universal suction disc 67 to slightly move and rotate up and down, so that the door leaf is driven to slightly move and is matched with 1 person on the carriage to ensure that the door leaf is connected with the door leaf on the train and the lower swing arm is unhooked.
After the door leaf is unhooked, the door leaf is rotated to the horizontal position, the whole machine is pushed to aim at a door leaf shelf to move, the laser sensor is used for detecting that the door leaf is stopped after reaching a specified position, then the oil cylinder 33 is started to enable the lifting plate 4 to move downwards to a low position to touch a dead stop iron 11 with a lower limit, the ball screw mechanism 54 is used for driving the door leaf to move to about 20mm away from the bottom of the door leaf shelf, finally the vacuum sucker is used for releasing negative pressure, the door leaf is enabled to freely fall to the specified position of the door leaf shelf, and a cycle of detaching the door leaf is completed.
When the door leaf is installed, the door leaf on the door leaf shelf needs to be grabbed by the sucker and then loaded into the installation frame of the train. The specific process is as follows:
firstly, the four-bar swing arm 66 and the universal suction cup 67 are rotated to be in a horizontal position and are lowered to a low position, namely an initial position, the whole machine is pushed to be aligned to a door leaf to be installed manually, and when the four suction cups 671 just contact the door leaf, the ball screw mechanism 54 is driven to drive the four-bar swing arm 66 and the universal suction cup 67 to move downwards by about 20mm; then, the four suckers 671 are pushed manually to effectively press the door leaf, the vacuum generator is started until negative pressure indicates-86 MPa, and after the pressure reaches the standard, the ball screw mechanism 54 is driven to drive the swing arm 66, the universal sucker 67 and the grabbed door leaf to move upwards to separate from a door leaf shelf; then, the whole machine is continuously moved and indexed to be aligned to the position of a train door leaf to be installed, the oil cylinder 33 and the ball screw mechanism 54 are simultaneously started, the four-rod swing arm 66 and the universal suction cup 67 move upwards together with the door leaf, and the whole machine is automatically stopped after the angle sensor detects a specified position; the gear motor 612 is started to enable the four-rod swing arm 66 and the universal suction cup 67 to rotate by 90 degrees, so that the door leaf is converted into a vertical state from a horizontal state, the whole machine is pushed to the position of a train for installing the door leaf, the manual coded disc is utilized to operate the swing arm 66 and the universal suction cup 67 to ascend and rotate to perform micro-motion after the door leaf is in place, and the door leaf swing arm on the train are hooked by aligning with 1 person on the carriage in an interactive mode.
After the door leaf is hooked, the wireless code disc stops acting immediately, and 1 person on the carriage carries out the positioning of the door leaf positioning pin and the door carrying frame on the train and tightens the screw. At the moment, the vacuum generator releases the negative pressure of the sucker for unloading, the sucker is separated from the train door leaf, and a cycle of 'mounting the door leaf' is completed.
