In summary, the assembly process of the magnetic levitation vehicle can be set as follows: firstly, placing cushion blocks in sequence according to the position of a supporting point of an interlayer 02, hoisting the interlayer 02 above a rail 01 by using a special hoisting tool (a first hoisting tool), adjusting the interlayer 02 to be basically aligned with the rail 01, and hovering the interlayer 02 when the distance between the interlayer 02 and the upper part of a skid is about 30 mm; then, two first slippage alignment devices 1 are installed on a rail 01, two ends of an interlayer 02 are respectively installed, the position of a shifting fork 15 in each first slippage alignment device 1 is adjusted and clamped on a car coupler 14 at two ends of the interlayer 02, openings of the shifting forks 15 are divided into two types, the two types of openings correspond to the width size of the car coupler 14 respectively, when the device is used, a rocking wheel 11 is rotated, a lead screw 12 drives the shifting fork 15 to move along a first slide rail 13, the shifting fork 15 clamps the car coupler 14, the rocking wheel 11 is continuously rotated, so that the shifting fork drives the interlayer 02 to move left and right, the center of the interlayer 02 can be adjusted to be aligned with the central line of the rail 01 according to the scale indication of '0' of a graduated scale 16, the interlayer 02 continuously falls to contact with a cushion block, a lifting appliance is removed after the interlayer 02 completely falls on the cushion block on the rail 01, a suspension support mechanism 2 is installed in the interlayer 02 after the interlayer 02, so that the vehicle body 03 is connected with the vehicle body 03 after being synthesized with the interlayer 02.
Thirdly, uniformly distributing 8 elevators on two sides of the interlayer 02, connecting a cable connecting the lifting device 5 and the control console with a power supply, adjusting the height of the lifting device 5 to enable a supporting seat of the lifting device 5 to be about 300mm higher than the interlayer 02, then using a second lifting appliance to lift the car body 03 to the upper part of the interlayer 02, slowly descending, rotating the longitudinal and transverse rocking wheels 45 to enable the guide pillar 42 to be inserted into the pin hole, rotating the longitudinal rocking wheel 44 again to enable the guide pillar 42 to drive the car body 03 to move so as to realize the longitudinal alignment of the car body 03 and the interlayer 02, and rotating the transverse rocking wheel 45 to enable the guide pillar 42 to drive the car body 03 to move so as to realize the transverse alignment of the car body 03 and the interlayer 02; the position of the lifting device 5 is adjusted to be aligned with the supporting point of the underframe of the car body 03, and the lifting device is adjusted to be vertical to the ground through the supporting leg of the lifting device 5 and is locked. In this way, raising the lifting device 5 can hold the body 03 bottom sill, at which point the second spreader can be removed, and the lifting device 5 can be slowly lowered, at which point the guide post 42 can guide the body 03 down until the body 03 is attached to the sandwich 02.
After the vehicle body 03 is attached to the interlayer 02, checking whether the alignment size of the vehicle body 03 and the interlayer 02 meets the technical requirements, and connecting the vehicle body 03 and the interlayer 02 into a whole by using bolts and rivets; after that, the lifting device 5 is slightly lifted for a certain distance, so that the vehicle body 03 and the interlayer 02 are lifted together, at the moment, the cushion blocks under the interlayer 02 can be withdrawn, the lifting device 5 is lowered, and the vehicle body 03 and the interlayer 02 fall back to the normal position.
And finally, connecting the suspension frame supporting mechanism 2 pre-installed in the interlayer 02 with the vehicle body 03, then continuously dropping the vehicle body 03 to the lifting device 5 to be separated from the side beam of the vehicle body 03, after the suspension frame supporting mechanism 2 can completely support the weight of the vehicle, withdrawing the lifting device 5, and finishing the assembly and synthesis of the magnetic levitation vehicle.
It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
The assembling tool and the assembling method of the magnetic levitation vehicle provided by the invention are described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
