Description

Technical Field

[0001] This application relates to the field of caisson installation technology, and in particular to a hoisting and positioning device for caissons. Background Technology

[0002] Currently, caissons are common large precast reinforced concrete components in waterway engineering, often installed at wharves, breakwaters, and offshore bridge piers. A caisson is a box-shaped structure with a top but no bottom, which needs to be prefabricated as a whole and then hoisted to the wharf or other location for installation.

[0003] During the hoisting and lowering process, it is crucial to maintain the caisson's horizontal position to prevent tilting and potential safety hazards. The traditional method involves installing a GPS positioning structure on the caisson. The GPS information is used to determine if the caisson is tilting, and the release length of the steel cables at different locations is adjusted accordingly. However, this traditional method has several drawbacks: Firstly, according to the existing patent (CN212772503U), the GPS positioning structure needs to be disassembled and reassembled before and after each caisson's hoisting. Each installation requires precise adjustment of the relative position of the GPS positioning structure to the caisson, which is cumbersome due to the repeated disassembly. Furthermore, some caissons are located on the seabed after installation, necessitating diving for disassembly. Secondly, this method only allows adjustment of the caisson's horizontal state, not its horizontal position, making it difficult to accurately locate the caisson.

[0004] Therefore, there is a need for a hoisting and positioning device that does not require disassembly and reassembly of the GPS positioning structure during each hoisting operation and can adjust the horizontal position of the caisson. Utility Model Content

[0005] Therefore, it is necessary to provide a hoisting and positioning device for caissons, and its specific technical solution is as follows.

[0006] A hoisting and positioning device for caissons, comprising:

[0007] A first rectangular hanger is equipped with winches at its four corners; the winches are used to wind up or release the first wire rope.

[0008] The second rectangular hanger is located below the first rectangular hanger; the four corners of the second rectangular hanger are respectively connected to the first wire rope of the winch;

[0009] The X-axis moving assembly is mounted on the second rectangular hanger;

[0010] The third rectangular hanger is located below the second rectangular hanger; the third rectangular hanger is connected to the X-axis moving component, which drives the third hanger to move along the X-axis direction; at least three limiting posts that are not on the same straight line are connected to the bottom surface of the third rectangular hanger, and the limiting posts abut against the top of the caisson, so that the top of the caisson is parallel to the third rectangular hanger.

[0011] The Y-axis moving component is mounted on the third rectangular hanger; the Y-axis moving component is connected to the caisson and is used to drive the caisson to move along the Y-axis direction;

[0012] GPS-RTK mobile stations, multiple GPS-RTK mobile stations are mounted on a third rectangular bracket.

[0013] Furthermore, the X-axis moving assembly includes a first moving trolley, a second steel wire rope, and a first hydraulic cylinder; the first moving trolley is movably mounted on a second rectangular hanger along the X-axis direction; one end of the second steel wire rope is connected to the first moving trolley, and the other end is connected to a third rectangular hanger; one end of the first hydraulic cylinder is connected to the second rectangular hanger, and the other end is connected to the first moving trolley.

[0014] The Y-axis moving assembly includes a second moving trolley, a third steel wire rope, and a second hydraulic cylinder; the second moving trolley is movably mounted on a third rectangular hanger along the Y-axis direction; one end of the third steel wire rope is connected to the second moving trolley, and the other end is connected to the caisson; one end of the second hydraulic cylinder is connected to the third rectangular hanger, and the other end is connected to the second moving trolley.

[0015] Furthermore, the second rectangular hanger includes four first rods connected end to end; the first rods have a gap in the middle to accommodate the passage of the second steel wire rope.

[0016] Furthermore, the first rod body has a wing plate on its edge; the first moving trolley includes a vehicle body, a roller and a reverse hook plate; the roller is rotatably mounted on the bottom of the vehicle body and presses against the top of the first rod body; the reverse hook plate is mounted on the side of the vehicle body and extends under the wing plate and abuts against the bottom of the wing plate.

[0017] Furthermore, the second rectangular hanger is provided with four X-axis moving components arranged in a rectangular array; the third rectangular hanger is provided with four Y-axis moving components arranged in a rectangular array.

[0018] Furthermore, the limiting post is a third hydraulic cylinder.

[0019] Furthermore, the bottoms of the multiple limiting posts are on the same plane.

[0020] Beneficial effects: The hoisting and positioning device for caissons provided by this utility model, on the one hand, restricts the third rectangular gantry to remain parallel to the top of the caisson by limiting columns. The GPS-RTK mobile station is installed on the third rectangular gantry, and the level of the caisson can be monitored by monitoring the level of the third rectangular gantry, eliminating the need to disassemble and assemble the GPS-RTK mobile station each time, thus reducing workload. On the other hand, the horizontal displacement is adjusted by using X-axis and Y-axis moving components, which can adjust the horizontal position of the caisson. Based on the level of the caisson monitored by the GPS-RTK mobile station, the level of the caisson can be adjusted by adjusting the release length of each first wire rope by the winch, thereby enabling accurate positioning of the caisson.

[0037] Example

[0038] This embodiment provides a hoisting and positioning device for caissons, referring to... Figure 1 As shown, it includes a first rectangular hanger 1, a second rectangular hanger 2, an X-axis moving component 3, a third rectangular hanger 4, a Y-axis moving component 5, and a GPS-RTK mobile station 6.

[0039] Specifically, winches 11 are installed at the four corners of the first rectangular gantry 1; the winches 11 are used to wind up or release the first wire rope 12. By releasing the first wire rope 12 through the winches 11, the caisson can be lowered, and by adjusting the release length of the first wire rope 12 of different winches 11, the level of the caisson can be adjusted.

[0040] The second rectangular hanger 2 is located below the first rectangular hanger 1; its four corners are connected to the first wire rope 12 of the winch 11. The X-axis moving assembly 3 is mounted on the second rectangular hanger 2. The third rectangular hanger 4 is located below the second rectangular hanger 2; it is connected to the X-axis moving assembly 3 and is driven by the X-axis moving assembly 3 to move along the X-axis; at least three non-linear limiting posts 41 are connected to the bottom surface of the third rectangular hanger 4, and these limiting posts 41 abut against the top of the caisson, making the top of the caisson parallel to the third rectangular hanger 4. By using the limiting posts 41 to restrict the caisson's top from being parallel to the third rectangular hanger 4, the horizontal status of the caisson can be monitored by monitoring the horizontal status of the third rectangular hanger 4.

[0041] The Y-axis moving component 5 is mounted on the third rectangular hanger 4; the Y-axis moving component 5 is connected to the caisson and is used to move the caisson along the Y-axis direction. The X-axis moving component 3 moves the third rectangular hanger 4 along the X-axis direction, thereby causing the Y-axis moving component 5 to move the caisson along the Y-axis direction, thus adjusting the position of the caisson in the X and Y directions and ensuring accurate positioning of the caisson.

[0042] Multiple GPS-RTK mobile stations 6 are installed on the third rectangular gantry 4. By monitoring the coordinates of their respective positions using the GPS-RTK mobile stations 6, the horizontal status of the third rectangular gantry 4 can be determined, thereby monitoring the horizontal status of the caisson. When the caisson is not horizontal, its horizontal status can be adjusted by adjusting the release length of the first wire rope 12 of different winches 11.

[0043] The lifting and positioning device for caissons provided in this embodiment, on the one hand, restricts the third rectangular gantry 4 to remain parallel to the top of the caisson by limiting column 41, and installs GPS-RTK mobile station 6 on the third rectangular gantry 4. The level of the caisson can be monitored by monitoring the level of the third rectangular gantry 4, without having to disassemble and assemble GPS-RTK mobile station 6 every time, thus reducing workload; on the other hand, the horizontal displacement is adjusted by using X-axis moving component 3 and Y-axis moving component 5, which can adjust the horizontal position of the caisson. According to the level of the caisson monitored by GPS-RTK mobile station 6, the level of the caisson can be adjusted by adjusting the release length of each first wire rope 12 by winch 11, thereby enabling accurate positioning of the caisson.

[0044] Specifically, refer to Figure 1 As shown, the X-axis moving assembly 3 includes a first moving trolley 31, a second steel wire rope 32, and a first hydraulic cylinder 33; the first moving trolley 31 is movably mounted on a second rectangular hanger 2 along the X-axis direction; one end of the second steel wire rope 32 is connected to the first moving trolley 31, and the other end is connected to a third rectangular hanger 4; one end of the first hydraulic cylinder 33 is connected to the second rectangular hanger 2, and the other end is connected to the first moving trolley 31.

[0045] The Y-axis moving assembly 5 includes a second moving trolley 51, a third steel wire rope 52, and a second hydraulic cylinder 53. The second moving trolley 51 is movably mounted on a third rectangular hanger 4 along the Y-axis direction. One end of the third steel wire rope 52 is connected to the second moving trolley 51, and the other end is connected to the caisson. One end of the second hydraulic cylinder 53 is connected to the third rectangular hanger 4, and the other end is connected to the second moving trolley 51. The first moving trolley 31 is moved by the first hydraulic cylinder 33, and the second moving trolley 51 is moved by the second hydraulic cylinder 53, thereby adjusting the horizontal position of the caisson.

[0046] Specifically, the second rectangular hanger 2 includes four first rods 21 connected end to end; the first rods 21 have a gap 22 in the middle to accommodate the passage of the second steel wire rope 32. Correspondingly, the third rectangular hanger 4 includes four second rods connected end to end; the second cylinder has a gap 22 in the middle to accommodate the passage of the third steel wire rope 52. This facilitates the movement of the first moving trolley 31 and the second moving trolley 51.

[0047] Specifically, the first rod 21 has a wing plate 23 on its edge; the first moving trolley 31 includes a body 311, a roller 312, and a hook plate 313; the roller 312 is rotatably mounted on the bottom of the body 311 and presses against the top of the first rod 21; the hook plate 313 is mounted on the side of the body 311 and extends below the wing plate 23, abutting against the bottom of the wing plate 23. By setting the roller 312, the first moving trolley 31 can move relative to the first rod 21, and by the cooperation of the hook plate 313 and the wing plate 23, the relative stability of the first moving trolley and the first rod 21 can be maintained.

[0048] It should be noted that the structure of the second mobile trolley 51 is the same as that of the first mobile trolley 31, and will not be described in detail in this embodiment.

[0049] Specifically, the second rectangular hanger 2 is equipped with four X-axis moving components 3 arranged in a rectangular array; the third rectangular hanger 4 is equipped with four Y-axis moving components 5 arranged in a rectangular array. The stability of the third rectangular hanger 4 and the caisson is maintained by respectively setting four X-axis moving components 3 and four Y-axis moving components 5.

[0050] Specifically, the limiting post 41 is a third hydraulic cylinder. Since the third wire rope 52 will expand and contract to different degrees when hoisting caissons of different weights, the unified expansion and contraction of the third hydraulic cylinder can ensure that the end of the third hydraulic cylinder abuts against the caisson and that the bottom surface of the third hydraulic cylinder is on the same plane.

[0051] It should be noted that in this embodiment, there are four third hydraulic cylinders, which are located at the four corners of the third rectangular hanger 4.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
