In addition, the door-shaped frame 13 can improve the strength and bearing capacity of the whole support beam frame 1 and avoid overload deformation of the support beam frame 1.

Referring to fig. 2 and 6, the three-layered work platform 3 includes a plurality of rail beam sections 31 arranged along the traveling direction of the train 200 to be serviced, the rail beam sections 31 being disposed between adjacent two support beam frames 1, each rail beam section 31 including a first rail beam 311 and a second rail beam 312. The first rail beam 311 and the second rail beam 312 are each movably provided on the second mounting beam 12 in the width direction thereof so that the first rail beam 311 and the second rail beam 312 can be switched between an open state and a closed state. That is, the first rail beam 311 and the second rail beam 312 may be close to and distant from each other in the width direction. In the closed state, the travelling wheels 2011 of the bogie 201 of the train 200 to be overhauled are suspended on the first rail beam 311 and the second rail beam 312 in a rolling travelling manner; in the open state, the bogie 201 of the train 200 to be serviced can be transported out through the gap between the first rail beam 311 and the second rail beam 312 under the drive of the hoisting device.

The first rail beam 311 and the second rail beam 312 are initially in a closed state. When the train 200 to be overhauled needs to be overhauled, the train enters an overhauling stock way along the running track beam 100, the bogie 201 of the train 200 to be overhauled is hung on the first track beam 311 and the second track beam 312 which are in the closed state, and the train is stopped after running to a specified overhauling position along the first track beam 311 and the second track beam 312. Specifically, referring to fig. 5, the left and right traveling wheels 2011 and 2011 of the bogie 201 roll on the first and second rail beams 311 and 312, respectively, until a designated service position is reached. After stopping, the AGV trolley carries the car body support frame tool to move along the appointed direction, enters the lower part of the train 200 to be overhauled and adjusts the pose, lifts upwards after being accurately aligned with the lifting point of the car body frame of the train 200 to be overhauled, slightly lifts the whole car, then, an operator dismantles the bogie 201 and the car body at the two-layer operation platform 2, and the hoisting equipment hangs the bogie 201 to release the load applied on the first track beam 311 and the second track beam 312 by the bogie 201. Then, the first rail beam 311 and the second rail beam 312 are moved away from each other to switch to the open state, the lifting device lifts the bogie 201, moves the bogie 201 out of the maintenance platform after passing through the gap between the first rail beam 311 and the second rail beam 312, lifts the new fault-free bogie 201 to the upper part of the train 200 to be maintained, and then the operator installs the new bogie 201 on the two-layer work platform 2 to the roof of the train 200 to be maintained. After the bogie 201 is installed, the first rail beam 311 and the second rail beam 312 are closed.

It should be noted that, a gap still exists between the first rail beam 311 and the second rail beam 312 in the closed state, so as to penetrate through a narrower portion in the middle of the bogie 201. When the connection between the lower portion of the bogie 201 and the roof of the train 200 to be serviced is removed, the first rail beam 311 and the second rail beam 312 are opened to enlarge the gap, allow the wider lower portion of the bogie 201 to pass through the gap, and move out of the service platform under the lifting of the lifting device.

After the pressure on the first track beam 311 and the second track beam 312 is unloaded (the AGV trolley supports the train 200 to be overhauled, the lifting device lifts the bogie 201, the train 200 to be overhauled is not hung on the first track beam 311 and the second track beam 312 any more), the rotation driving piece 61 is started, the rotation driving piece 61 drives the driving pulley 621 to rotate, and then the driving pulley 621 drives the driven pulley to rotate through the synchronous conveyor belt 622, the extending direction of the synchronous conveyor belt 622 is consistent with the width direction of the first track beam 311 and the second track beam 312, and in the conveying process, the first track beam 311 and the second track beam 312 can be driven to move relative to the second installation beam 12, so that the opening and closing of the first track beam 311 and the second track beam 312 are realized.

When the first rail beam 311 and the second rail beam 312 are moved to the closed state, the positioning sleeve 74 is vertically opposite to the guide sleeve 73, and the latch 72 is moved downward to be inserted into the positioning sleeve 74.

Referring to fig. 6, both ends of the first rail beam 311 and the second rail beam 312 in the length direction are provided with locking units 7 so that they are firmly locked.
