One component is slowly pushed toward the other, and the corresponding holes and pins are manually adjusted and aligned before insertion.

[0050] Working principle:

[0051] When in use, the guide rail frame structure 5, the horizontal angle adjustment assembly 6 and the electric hoist lifting assembly 7 cooperate to lift the two large cylindrical components and move them to the radial lifting platform assemblies 9 at both ends of the docking workbench 1 along its length direction; the two large cylindrical components are driven by the axial drive moving assembly 3 to move closer to each other, and when the two large cylindrical components are close to each other, the turnover drive assembly 8 drives the two large cylindrical components to rotate around their central axis at a certain angle, so that the mounting holes correspond to each other;

[0052] Specifically, according to the size of the outer diameter of the cylindrical large component, the electric telescopic rod 207 of the rotary support assembly 2 can first drive the two V-shaped support rods 202 to hinge and rotate under the support of the hinge seat 201, so that the two V-shaped support rods 202 rotate to each other, so that the support angle of the two V-shaped support rods 202 is adapted to the size of the outer diameter of the cylindrical large component. When the axial driving moving assembly 3 drives the cylindrical large component to move, the lifting driving assembly 4 first drives the axial driving moving assembly 3 to move upward, so that the axial driving wheel 3b of the axial driving moving assembly 3 abuts against the bottom side of the cylindrical large component, and then props up the cylindrical large component to a certain height, so that the cylindrical large component and the first supporting wheel 203 and the second supporting wheel 204 of the V-shaped support rod 202 are separated to a certain gap, and then the output shaft of the first motor 3c in the axial driving wheel 3b rotates, thereby driving the axial driving wheel 3b to rotate to realize the axial movement of the cylindrical large component;

[0053] After the butt ends of the two cylindrical large components are in contact with each other, the cylindrical large components need to be adjusted in angle along their circumferential direction. At this time, the lifting drive assembly 4 drives the axial drive moving assembly 3 to descend, so that the axial drive wheel 3b is separated from the bottom side of the cylindrical large component, and then the outer side of the cylindrical large component is again in contact with the first support wheel 203 and the second support wheel 204 at both ends of the V-shaped support rod 202, so that the cylindrical large component can be rotated along its circumferential direction under the support of the first support wheel 203 and the second support wheel 204, and the second hydraulic cylinder 502 of the guide rail frame structure 5 can drive the up and down height of the track 505 to be adjusted, so that the circumferential drive wheel 802 of the circumferential drive assembly 8 is in contact with the upper side of the cylindrical large component, and then the second hydraulic cylinder 502 can drive the height of the track 505 to move downward, so that the circumferential The rotating driving wheel 802 is elastically pressed against the upper side of the cylindrical large component under the elastic force of the second spring 805 to increase the friction. At this time, there is a certain gap between the pressure pad 705 and the cylindrical large component. The revolving driving wheel 802 rotates under the drive of the third motor 803 inside it, thereby driving the cylindrical large component to rotate a certain angle under the support of the rotary support assembly 2, so that the mounting holes of the two cylindrical large components can be assembled corresponding to each other. After alignment, the second hydraulic cylinder 502 can drive the height of the track 505 to continue to move downward until the upper side of the pressure pad 705 and the upper side of the cylindrical large component abut against each other, and under the action of the first spring 709, the cylindrical large component is elastically pressed, which plays a role of stopping and pressing. After the docking assembly is completed, the two electric hoist lifting assemblies 7 can lift and unload the cylindrical large component.
