Description

Technical Field

[0001] The present invention relates to the technical field of lifting devices, and particularly relates to a precast segment assembly lifting device and a using method thereof. Background Art

[0002] Segmental assembly is a common assembly method and is widely used in various production fields. In the current segment assembly process, the equipment mainly includes a transverse movement device and a conventional hoisting device. Among them, for the erection and docking of small segments, it mainly depends on the method of hoisting or transverse movement after hoisting combination to complete. When using a hoisting device to splice small segments, the hoisting device first hoists the segment to a predetermined installation position, and then, through manual operation, the segment is connected and fixed. After being connected into a main body, the segment is integrally transversely moved by the transverse movement device;

[0003] However, in the actual operation process, there are relatively obvious technical problems in the docking process between the segment hoisted by the hoisting device and the existing one. Hoisting is greatly affected by the external environment, such as wind speed, and it is necessary to combine manual command and instrument monitoring to ensure the hoisting accuracy. This method has the problem of low information transmission efficiency, and the progress of the entire hoisting and docking process is relatively slow. Therefore, the present invention proposes a precast segment assembly lifting device and a using method thereof. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides the following technical solution: A precast segment assembly lifting device includes a translation component, a jacking component, a rotating component, and a rotation measurement component;

[0006] The translation component is arranged on the top of an external temporary support;

[0007] The jacking component is arranged on the top of the translation component, the rotating component is arranged on the top of the jacking component, and the rotating component is used to support the segment;

[0008] The rotation measurement component is arranged between the jacking component and the rotating component;

[0009] The jacking component jacks up the rotating component, the rotating component drives the segment to rotate, the rotation measurement component monitors the rotation data of the rotating component, and the translation component drives the jacking component, the rotating component, and the segment on the rotating component to synchronously transversely move for the docking of segment pre-assembly.

[0010] Preferably, the translation component includes a grounding base plate, a slideway, a sliding support frame, a push plate, a hydraulic push rod seat and a hydraulic push rod. The grounding base plate is arranged on the top of the temporary support and fixed to the temporary support by bolts. The slideway is opened on the side of the grounding base plate. The sliding support frame is arranged inside the slideway and restricted by the slideway. The push plate is welded to the side wall surface of the sliding support frame. The hydraulic push rod seat is welded to the surface of the grounding base plate, and the hydraulic push rod seat and the push plate are on the same horizontal line. The hydraulic push rod is installed between the push plate and the hydraulic push rod seat. The sliding support frame and the push plate are pushed by the hydraulic push rod.

[0011] Preferably, the bottom width of the sliding support frame is the same as the inner width of the slideway. Lubricating oil for lubrication is applied between the slideway and the sliding support frame. Two groups of sliding support frames are arranged side by side on the surface of the grounding base plate through the slideway. An adjustment space for the lifting component to move up and down is formed between the two groups of sliding support frames.

[0012] Preferably, the lifting component includes a lifting support frame, a support seat, a support rod, a lifting plate, a hydraulic rod base and a hydraulic lifting rod. The lifting support frame is erected between two groups of sliding support frames and fixedly connected to the two groups of sliding support frames by bolts. The support seat is fixedly welded to the side of the lifting support frame. Two groups of support seats are fixed on each side of the lifting support frame. The support rod is arranged inside the support seat, and the support rod can slide vertically relative to the support seat. The lifting plate is fixed between the tops of the four support rods. The hydraulic rod base is arranged at the middle position of the grounding base plate. The hydraulic lifting rod is installed at the central position of the hydraulic rod base. The top of the output end of the hydraulic lifting rod is connected to the central position of the lifting plate.

[0013] Preferably, the lifting component further includes a reinforcing plate. The reinforcing plate is arranged at the middle position of the bottom of the lifting support frame. A through hole is opened at the middle position of the reinforcing plate. The hydraulic lifting rod passes through the through hole. The reinforcing plate limits the middle part of the hydraulic lifting rod through the through hole.

[0014] Preferably, the rotating component includes a driven wheel, a driving wheel, a reduction motor and a segment support plate. The driven wheel is installed at the central position of the top of the lifting plate through a bearing. The driving wheel is installed on the surface of the lifting plate through a transmission shaft. The driving wheel meshes with the driven wheel. The reduction motor is installed on one side of the bottom of the lifting plate. The output end of the reduction motor is connected to the transmission shaft. The driving wheel is driven by the reduction motor. The segment support plate is arranged at the middle position of the top of the driven wheel. The segment support plate is driven by the driven wheel.

[0015] Preferably, the rotation measurement assembly includes a sensor bracket, a rotational speed sensor, an angle sensor, and a sensor calibration plate. The sensor bracket is disposed on the surface of the lifting plate. The rotational speed sensor and the angle sensor are arranged side by side inside the sensor bracket. The sensor calibration plate is disposed at the bottom of the segment support plate.

[0016] Preferably, the rotation measurement assembly further includes a rotation limit seat. The rotation limit seat is disposed on one side of the rotational speed sensor, and the end of the rotation limit seat abuts against the surface of the sensor calibration plate.

[0017] Preferably, there are two sets of rotational speed sensors. Angle sensors and sensor calibration plates are disposed inside both sets of rotational speed sensors. The two sets of rotational speed sensors are symmetrically distributed with the driven wheel as the center of symmetry.

[0018] The using method of the precast segment assembling hoisting device includes the following steps:

[0019] Step S1: Install several groups of temporary support brackets in front of the bridge pier according to the pre-simulated assembling sequence, and install the precast segment assembling hoisting device in the temporary support brackets;

[0020] Step S2: Hoist the segments according to the pre-simulated segment assembling sequence, and hoist the current segment onto the surface of the segment support plate;

[0021] Step S3: Measure the point cloud data of the current segment and the existing segments on the surface of the segment support plate through an external laser ranging assembly. The external computing device creates a supervoxel point cloud model of the current segment and the existing segments, forms the spatial position information of the current segment relative to the existing segments, conducts simulated pre-assembling of the segments through the supervoxel point cloud model, and obtains the splicing adjustment data of the current segment and the segments through the simulated pre-assembling. The adjustment data includes the docking height, the docking spacing, and the docking angle;

[0022] Step S4: Adjust the relative angle between the current segment and the existing segments, that is, the docking angle. The speed reduction motor first operates to drive the driving wheel to rotate. The driving wheel drives the driven wheel to rotate. The segment support plate rotates synchronously under the drive of the driven wheel. The current segment placed on the top surface of the segment support plate rotates slowly synchronously under the drive of the segment support plate;

[0023] Step S41: During the rotation of the segment support plate, the sensor calibration plate changes its position relative to the rotational speed sensor and the angle sensor. The rotational speed sensor and the angle sensor measure the parameters between them in real time during the rotational movement of the sensor calibration plate. The parameters obtained by the rotational speed sensor and the angle sensor are synchronously transmitted to the external computing device. The external computing device compares the obtained data with the splicing adjustment data obtained through simulation. When the data is consistent, the speed reduction motor stops operating, and the relative angle between the current segment and the existing segments reaches the docking angle;

[0024] Step S5: Adjust the height position of the current segment. The hydraulic jacking rod works and extends. The extension height of the hydraulic jacking rod is consistent with the docking height data. The hydraulic jacking rod pushes the jacking plate to move vertically, and the rotating assembly at the top of the jacking plate synchronously adjusts the set height. The current segment at the top of the rotating assembly is synchronously adjusted in height. At this time, the current segment is aligned with the existing segment in height.

[0025] Step S6: Adjust the lateral position of the current segment. The hydraulic push rod works to adjust its length. The active length of the hydraulic push rod is consistent with the docking spacing data. The hydraulic push rod extends to drive the push plate to drive the sliding support frame to move horizontally along the slideway. The jacking assembly, rotating assembly and current segment arranged on the top of the sliding support frame move horizontally synchronously, and the horizontally moving current segment approaches the existing segment.

[0026] Step S7: After the current segment and the existing segment are docked, the construction workers carry out the connection operation.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. The present invention is provided with a translation assembly, a jacking assembly, a rotating assembly and a rotation measurement assembly. The jacking assembly jacks up the rotating assembly, the rotating assembly drives the segment to rotate, the rotation measurement assembly monitors the rotation data of the rotating assembly, and the translation assembly drives the jacking assembly, the rotating assembly and the segment on the rotating assembly to move horizontally synchronously for the docking of segment pre-assembly. The whole process is not affected by the activities of the hoisting equipment, with good docking stability and high docking accuracy, improving the docking efficiency of the segments.

[0029] 2. The present invention cooperates with external laser measurement and super-voxel point cloud model for the simulated pre-assembly of segments, and can obtain high-accuracy splicing adjustment data of the current segment and segments in advance. The adjustment data includes docking height, docking spacing and docking angle. During the splicing process, there is no need for manual monitoring of docking data, further improving the docking efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following further elaborates the present invention in combination with the accompanying drawings and embodiments on the above and other technical features and advantages of the present invention. However, the following embodiments are only the preferred embodiments of the present invention, not all of them.

[0041] Embodiment:

[0042] As Figure 1 - Figure 8 shown, the present invention provides a precast segment assembling and hoisting device, including a translation component 1, a lifting component 2, a rotating component 3 and a rotating measurement component 4;

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

[0044] The lifting component 2 is arranged on the top of the translation component 1, the rotating component 3 is arranged on the top of the lifting component 2, and the rotating component 3 is used for supporting the segment;

[0045] The rotating measurement component 4 is arranged between the lifting component 2 and the rotating component 3;

[0046] The lifting component 2 jacks up the rotating component 3, the rotating component 3 drives the segment 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 segment on the rotating component 3 to move horizontally synchronously for the docking of segment pre-assembly.

[0047] After the hoisting equipment hoists the segment to the surface of the rotating assembly 3 and unhooks, the external laser ranging assembly measures the point cloud data of the current segment and the existing segments on the surface of the rotating assembly 3. The external computing device creates a supervoxel point cloud model of the segment to form the spatial position information of the current segment relative to the existing segments. The current segment is simulated and pre-assembled through the supervoxel point cloud model, and the splicing adjustment data of the current segment and the segments are obtained through the simulated pre-assembly. The adjustment data includes the segment height, the docking spacing, and the angle of the segment cross-section relative to the existing cross-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 to 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 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 extends, it pushes the push plate 14 to drive 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 currently moving segment approaches the existing segment. After the current segment and the existing segment are docked, they are connected by construction workers.

[0051] The bottom width of the sliding support frame 13 is consistent with the internal width of the slideway 12. Lubricating oil is applied between the slideway 12 and the sliding support frame 13. Two groups of sliding support frames 13 are arranged side by side on the surface of the grounding base plate 11 through the slideway 12. An adjustment space for the up and down movement of the jacking assembly 2 is formed between the two groups of sliding support frames 13. The jacking assembly 2 includes a jacking support 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 support 21 is installed between two sets of sliding support frames 13 and fixedly connected to the two sets of sliding support frames 13 by bolts. The support seat 22 is fixedly welded to the side of the jacking support 21. Two sets of support seats 22 are fixed on each side of the jacking support 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 support rods 23. The hydraulic rod base 25 is arranged at the middle position of the grounding bottom plate 11. The hydraulic jacking rod 26 is installed at the central position of the hydraulic rod base 25. The top of the output end of the hydraulic jacking rod 26 is connected to the central position of the jacking plate 24;

[0053] When adjusting the height position of the segment, the hydraulic jacking rod 26 works and extends. The extension height of the hydraulic jacking rod 26 is consistent with the docking height data. During the rising process of the hydraulic jacking rod 26, it pushes the jacking plate 24 to make the jacking plate 24 move vertically. The vertical movement of the jacking plate 24 causes the rotating assembly 3 on the top of the jacking plate 24 to synchronously adjust the set height, and the segment on the top of the rotating assembly 3 synchronously completes the height adjustment. At this time, the cross-section of the current segment is opposite to that of the existing segment.

[0054] The jacking assembly 2 further includes a reinforcing plate 27. The reinforcing plate 27 is arranged at the middle position of the bottom of the jacking support 21. A through hole is opened at the middle position of the reinforcing plate 27. 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 plays a role in limiting the middle part of the hydraulic jacking rod 26, thereby strengthening the hydraulic jacking rod 26 from the middle part of the hydraulic jacking rod 26, 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 central position of the top 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 meshes with the driven wheel 31. The reduction motor 33 is installed on one side of the bottom 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 arranged at the middle position of the top of the driven wheel 31. The segment support plate 34 is driven by the driven wheel 31;

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

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

[0059] The sensor holder 41 is disposed on the surface of the jacking plate 24. The rotational speed sensor 42 and the angle sensor 43 are installed side by side inside the sensor holder 41. The sensor calibration plate 44 is disposed at the bottom of the segment support plate 34. When the segment support plate 34 rotates, the sensor calibration plate 44 disposed at the bottom of the segment support plate 34 rotates synchronously with the segment support plate 34. During the rotation of the segment support plate 34, the sensor calibration plate 44 changes its setting position relative to the rotational speed sensor 42 and the angle sensor 43. The rotational 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 rotational movement of the sensor calibration plate 44. The distance and angle data obtained by the rotational speed sensor 42 and the angle sensor 43 are synchronously transmitted to an external computing device.

[0060] The rotation measurement assembly 4 further includes a rotation limit seat 45. The rotation limit seat 45 is disposed on one side of the rotational speed sensor 42. The end of the rotation limit seat 45 abuts against the surface of the sensor calibration plate 44. The rotation limit seat 45, in cooperation with the sensor calibration plate 44, keeps the setting position of the segment support plate 34 relative to the sensor holder 41 fixed, preventing the segment support plate 34 from over-rotating and colliding with the sensor holder 41, thereby avoiding damage to the rotational speed sensor 42 and the angle sensor 43 inside the sensor holder 41 due to the collision.

[0061] There are two sets of sensor holders 41. The rotational speed sensor 42 and the angle sensor 43 are both disposed inside the two sets of sensor holders 41. The two sets of sensor holders 41 are symmetrically distributed about the driven wheel 31 as the center of symmetry. The two sets of sensor holders 41 and the rotational speed sensor 42 and the angle sensor 43 inside them that are symmetrically distributed can synchronously obtain two sets of data, and the two sets of data can be cross-validated.

[0062] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
