[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0041] Example:

[0042] like Figure 1 - Figure 8 As shown, the present invention provides a prefabricated segment assembly lifting device, including a translation component 1, a lifting component 2, a rotation component 3 and a rotation measurement component 4;

[0043] The translation assembly 1 is arranged on the top of the external temporary support;

[0044] The lifting assembly 2 is arranged on the top of the translation assembly 1, and the rotating assembly 3 is arranged on the top of the lifting assembly 2, and the rotating assembly 3 is used to support the segment;

[0045] The rotation measuring assembly 4 is arranged between the lifting assembly 2 and the rotation assembly 3;

[0046] The lifting component 2 lifts the rotating component 3 upward, the rotating component 3 drives the segments to rotate, the rotating measurement component 4 monitors the rotation data of the rotating component 3, and the translation component 1 drives the lifting component 2, the rotating component 3 and the segments on the rotating component 3 to move horizontally synchronously to perform pre-assembly docking of the segments.

[0047] The lifting equipment lifts the segment to the surface of the rotating component 3 and then unhooks it. The point cloud data of the current segment and the existing segments on the surface of the rotating component 3 are measured by an external laser ranging component. The external computing device creates a super voxel point cloud model of the segment to form the spatial position information of the current segment relative to the existing segments. The super voxel point cloud model is used to simulate the pre-assembly of the current segment. The splicing adjustment data of the current segment and the segment are obtained through the simulated pre-assembly. The adjustment data includes the segment height, docking spacing and the angle of the segment section relative to the existing section.

[0048] The translation assembly 1 includes a grounding base plate 11, a slideway 12, a sliding support frame 13, a push plate 14, a hydraulic push rod seat 15 and a hydraulic push rod 16;

[0049] The grounding base plate 11 is arranged on the top of the temporary support and fixed with the temporary support by bolts, the slideway 12 is opened on the side of the grounding base plate 11, the sliding support frame 13 is arranged inside the slideway 12 and is restricted by the slideway 12, the push plate 14 is welded to the side wall surface of the sliding support frame 13, the hydraulic push rod seat 15 is welded to the surface of the grounding base plate 11, and the hydraulic push rod seat 15 and the push plate 14 are on the same horizontal line, the hydraulic push rod 16 is installed between the push plate 14 and the hydraulic push rod seat 15, and the sliding support frame 13 and the push plate 14 are pushed by the hydraulic push rod 16;

[0050] When adjusting the lateral position of the segment, the hydraulic push rod 16 works to adjust its length. The active length of the hydraulic push rod 16 is consistent with the docking spacing data. When the hydraulic push rod 16 is extended, it pushes the push plate 14 so that the push plate 14 drives the sliding support frame 13 to move horizontally along the slideway 12. When the sliding support frame 13 moves horizontally, the jacking assembly 2, the rotating assembly 3 and the segment arranged on the top of the sliding support frame 13 move horizontally synchronously. The current segment that moves horizontally is close to the existing segment. After the current segment and the existing segment are docked, they are connected by construction personnel.

[0051] The bottom width of the sliding support frame 13 is consistent with the inner width of the slideway 12. Lubricating oil is applied between the slideway 12 and the sliding support frame 13. Two sets of sliding support frames 13 are arranged side by side on the surface of the grounded bottom plate 11 through the slideway 12. An adjustment space for the jacking assembly 2 to move up and down is formed between the two sets of sliding support frames 13. The jacking assembly 2 includes a jacking bracket 21, a support seat 22, a support rod 23, a jacking plate 24, a hydraulic rod base 25 and a hydraulic jacking rod 26;

[0052] The jacking bracket 21 is erected between the two groups of sliding support frames 13 and is fixedly connected to the two groups of sliding support frames 13 by bolts. The support seat 22 is fixed to the side of the jacking bracket 21 by welding. Two groups of support seats 22 are fixed on both sides of the jacking bracket 21. The support rod 23 is arranged inside the support seat 22, and the support rod 23 can slide vertically relative to the support seat 22. The jacking plate 24 is fixed between the tops of the four groups of support rods 23. The hydraulic rod base 25 is arranged at the middle position of the grounded bottom plate 11. The hydraulic jacking rod 26 is installed at the center position of the hydraulic rod base 25. The top of the output end of the hydraulic jacking rod 26 is connected to the center position of the jacking plate 24.

[0053] When adjusting the segment height position, the hydraulic lifting rod 26 is extended, and the extended height of the hydraulic lifting rod 26 is consistent with the docking height data. The hydraulic lifting rod 26 pushes the lifting plate 24 during the rising process to move the lifting plate 24 vertically. The vertical movement of the lifting plate 24 causes the rotating component 3 on the top of the lifting plate 24 to synchronously adjust the setting height, and the segment on the top of the rotating component 3 synchronously completes the height adjustment. At this time, the current segment is relative to the cross-section of the existing segment.

[0054] The jacking assembly 2 also includes a reinforcing plate 27, which is arranged at the middle position of the bottom of the jacking bracket 21. A through hole is opened in the middle position of the reinforcing plate 27, and the hydraulic jacking rod 26 passes through the through hole. The reinforcing plate 27 limits the middle part of the hydraulic jacking rod 26 through the through hole. The reinforcing plate 27 limits the middle part of the hydraulic jacking rod 26, thereby reinforcing the hydraulic jacking rod 26 from the middle part, improving the setting stability of the hydraulic jacking rod 26 and further improving the structural strength of the device.

[0055] The rotating assembly 3 includes a driven wheel 31, a driving wheel 32, a reduction motor 33 and a segment support plate 34;

[0056] The driven wheel 31 is installed at the top center of the jacking plate 24 through a bearing, the driving wheel 32 is installed on the surface of the jacking plate 24 through a transmission shaft, the driving wheel 32 is meshed with the driven wheel 31, the reduction motor 33 is installed on the bottom side of the jacking plate 24, the output end of the reduction motor 33 is connected to the transmission shaft, the driving wheel 32 is driven by the reduction motor 33, the segment support plate 34 is set at the middle position of the top of the driven wheel 31, and the segment support plate 34 is driven by the driven wheel 31;

[0057] When adjusting the relative angle of the segments, the reduction motor 33 works to drive the driving wheel 32 to rotate, and the driving wheel 32 drives the driven wheel 31 to rotate by meshing with the driven wheel 31. The segment support plate 34 rotates synchronously with the driven wheel 31, and the current segment placed on the top surface of the segment support plate 34 rotates synchronously with the segment support plate 34. The required rotation angle of the segment support plate 34 is consistent with the segment cross-sectional angle, and the rotation stops after the current segment cross-section is aligned with the existing segment cross-section.

[0058] The rotation measurement assembly 4 includes a sensor frame 41, a rotation speed sensor 42, an angle sensor 43 and a sensor calibration plate 44;

[0059] The sensor frame 41 is arranged on the surface of the lifting plate 24, the speed sensor 42 and the angle sensor 43 are installed side by side inside the sensor frame 41, and the sensor calibration plate 44 is arranged at the bottom of the segment pallet 34. When the segment pallet 34 rotates, the sensor calibration plate 44 arranged at the bottom of the segment pallet 34 rotates synchronously with the segment pallet 34. During the rotation of the segment pallet 34, the sensor calibration plate 44 changes the setting position of the speed sensor 42 and the angle sensor 43. The speed sensor 42 and the angle sensor 43 measure the distance and angle between them and the sensor calibration plate 44 in real time during the rotation and movement of the sensor calibration plate 44. The distance and angle data obtained by the speed sensor 42 and the angle sensor 43 are synchronously transmitted to the external computing device.

[0060] The rotation measuring assembly 4 also includes a rotation limit seat 45, which is arranged on one side of the speed sensor 42. The end of the rotation limit seat 45 contacts the surface of the sensor calibration plate 44. The rotation limit seat 45 cooperates with the sensor calibration plate 44 to keep the segment support plate 34 fixed in position relative to the sensor frame 41, thereby preventing the segment support plate 34 from being excessively reversed and causing a collision between the segment support plate 34 and the sensor frame 41, thereby preventing the speed sensor 42 and the angle sensor 43 in the sensor frame 41 from being damaged due to the collision.

[0061] There are two groups of sensor racks 41, and both groups of sensor racks 41 are provided with speed sensors 42 and angle sensors 43. The two groups of sensor racks 41 are symmetrically distributed with the driven wheel 31 as the center of symmetry. The two groups of sensor racks 41 and the speed sensors 42 and angle sensors 43 inside the sensor racks 41 can synchronously obtain two groups of data, and the two groups of data can be cross-verified.

[0062] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
