Description

Technical Field

[0001] This invention relates to the technical field of caisson towing equipment, specifically to a fixing structure and fixing method for caisson towing equipment. Background Technology

[0002] As a core load-bearing component, the underwater or near-water installation of the caisson requires towing equipment to complete the position adjustment. At present, the fixing structure for caisson towing operations mostly adopts traditional clamps, bolt connections or temporary counterweights to achieve force transmission and position locking between the towing equipment and the caisson.

[0003] In practice, this method suffers from low efficiency, high cost, and low safety. To address these issues, existing technology (Chinese patent application number CN201420229985.0, application date 2014-05-07) discloses a convenient caisson towing connection device. However, when the lateral movement direction differs from the traction direction of the pre-reserved traction hole, a protective device for the traction hole sidewall is required. This device aims to disperse the traction force pressure on the hole sidewall, preventing stress concentration in the connecting rope and potential damage to the caisson. Furthermore, existing technology (Chinese patent application number CN202410121432.1, application date 2024-01-30) discloses a double caisson towing connection device. This device can quickly connect and fix two caissons, and utilizes buoyancy to quickly detach the device from the caisson. Combined with compression and fixing around the caisson, final positioning is achieved. After positioning, the swaying between the caissons is absorbed by springs, ensuring stability during transportation and demonstrating strong practicality.

[0004] Although the above-mentioned device can be used for fixing, it still has some shortcomings when fixing and dragging the caisson. For example, when dragging the cable with the tow wheel, different situations will be encountered. When adjusting the position, the stress point of the cable will change. Multiple adjustments may even cause the cable to shift.

[0005] In view of this, a fixing structure and fixing method for caisson towing equipment are proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a fixing structure and fixing method for a caisson towing device, in order to solve the problem that the fixing structures currently on the market, as mentioned in the background art, face different situations when towing cables with tow wheels. When adjusting the position, the stress point of the cable changes, and multiple adjustments may even cause the cable to shift.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A fixing structure for a caisson towing device includes a fixed steel frame. A rear plate is fixed to the back of the fixed steel frame, and a U-shaped fitting block is embedded in the inner side of the rear plate. The U-shaped fitting block is locked to the rear plate by a locking bolt. A base plate is fixed to the bottom of the fixed steel frame. Drive motors are fixedly installed on the back of both sides of the base plate. The output end of the drive motor is connected to one end of a locking mechanism. The locking mechanism achieves the clamping action of the actuator end through the threaded transmission of a bidirectional threaded rod and a threaded connecting sleeve. The actuator end of the locking mechanism acts on the outside of the cable. A sway damping mechanism is linked to the outside of the locking mechanism. The sway damping mechanism acts on the outside of the cable. The sway damping mechanism moves synchronously with the locking mechanism through the meshing transmission of a fixed rack and a rotating gear. The rotating roller of the sway damping mechanism forms an elastic clamp on the cable to buffer the swaying force.

[0009] Preferably, a mating roller is rotatably provided inside the fixed steel frame, and a limiting mating block is fixed at one end of the mating roller near the inner side of the fixed steel frame. A cable passes through the limiting mating block and the inner side of the mating roller.

[0010] Preferably, the locking mechanism includes a bidirectional threaded rod fixedly connected to the output end of the drive motor. Both ends of the bidirectional threaded rod are threadedly connected to threaded connecting sleeves on their outer sides. A movable rod is rotatably connected to the bottom of the threaded connecting sleeve. The bottom of the movable rod is rotatably connected to the top inner side of the connecting shaft. The bottom of the connecting shaft is fixed to the top center of the pressure plate by bolts.

[0011] Preferably, a slider is fixed to the outer side of the pressure plate, and the outer side of the slider is slidably disposed on the inner side of the guide groove. The guide groove is opened on the inner side of the base plate, and a fixing plate is also fixedly disposed inside the base plate. Several sets of locking pins are fixed on the corresponding side of the fixing plate and the pressure plate.

[0012] Preferably, the upper and lower sets of locking pins are staggered, the outer side of the fixing plate acts on the outer side of the cable, the size of the fixing plate is the same as the size of the pressure plate, and the pressure plate forms a sliding structure between the slider and the inner side of the guide groove.

[0013] Preferably, the anti-sway mechanism includes a fixed rack fixed to one side of the slider, a rotating gear meshing with the outer side of the fixed rack, a rotating connecting sleeve fixed at the center of the rotating gear, a threaded tube threadedly connected to the inner side of the rotating connecting sleeve, and the other end of the threaded tube fixed to one side of the support frame.

[0014] Preferably, a rotating roller is rotatably provided on the outer side of the support frame, and two sets of guide rods are fixed on the rear side of the support frame, the guide rods being symmetrically arranged about the lateral center of the support frame.

[0015] Preferably, the outer side of the guide rod is slidably disposed inside the drive motor, the outer side of the rotating connecting sleeve is rotatably disposed inside the drive motor, and the support frame forms a sliding structure between the guide rod and the interior of the drive motor.

[0016] Preferably, an anti-slip pad is attached to the inner wall of the U-shaped bonding block, and the anti-slip pad is fixedly connected to the U-shaped bonding block by an adhesive method.

[0017] A method for fixing a caisson towing device is described below:

[0018] S1: Embed the U-shaped fitting block into the inner side of the rear plate, and lock the U-shaped fitting block to the rear plate with the locking bolt, so that the fixed steel frame forms a basic fixed structure through the rear plate, the sunken box and the U-shaped fitting block;

[0019] S2: Pass the cable through the inside of the fixed steel frame between the mating roller and the limiting mating block, so that the cable extends along the outside of the mating roller to the position of the corresponding locking mechanism on the base plate;

[0020] S3: Start the drive motors on the back of the left and right sides of the base plate. The output of the drive motor drives the locking mechanism to run, so that the execution end of the locking mechanism moves closer to the outside of the cable and fits against the cable, thus achieving the initial fixation of the cable.

[0021] S4: During the operation of the locking mechanism, the anti-sway mechanism linked to its outer side moves synchronously. The outer side of the anti-sway mechanism moves closer to the outer side of the cable as the locking mechanism moves, until the outer side of the anti-sway mechanism is in contact with the outer side of the cable.

[0022] S5: After the caisson towing operation is completed, start the drive motor in reverse to drive the locking mechanism's execution end away from the cable. The anti-sway mechanism will reset in conjunction with the locking mechanism. Then, remove the cable from between the mating roller and the limit mating block to complete the fixation release.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This caisson towing equipment employs a fixed structure and method. A U-shaped contact block, combined with anti-slip pads and locking bolts, is fixed to the rear plate, ensuring a stable connection between the fixed steel frame and the caisson foundation and preventing displacement. The locking mechanism uses a drive motor to power a bidirectional threaded rod, working in conjunction with the offset locking pins of the pressure plate and the fixed plate to enhance cable fixation and prevent slippage. The locking mechanism is linked to the anti-sway mechanism; the movement of the slider drives the fixed rack, rotating gears, and other components, ensuring the rotating rollers synchronously contact the cable, reducing cable swaying during towing and preventing damage caused by changes in stress points. Operationally, the fixing and releasing processes are clear. The forward and reverse rotation of the drive motor enables the linked actions of the components, improving work efficiency, reducing labor costs, and ensuring towing safety. This solves the problem of low efficiency in traditional fixing structures. The specific structure is shown below:

[0025] 1. The locking mechanism allows the pressure plate to slide along the guide groove of the base plate via a slider, ensuring a stable movement trajectory. Combined with the staggered design of the fixing plate and the pressure plate, as well as the locking pins, it can accommodate cables of different diameters and provides uniform clamping force, preventing localized damage to the cables. The rotating rollers of the anti-sway mechanism move synchronously with the locking mechanism, keeping in real time close to the cable and effectively buffering the shaking impact during dragging, further improving the overall stability and ensuring accurate positioning of the caisson during dragging.

[0026] 2. The locking mechanism's bidirectional threaded rod drive and pressure plate clamping avoid the problem of easy loosening of traditional clamps and bolts, reducing the risk of cable detachment; the anti-sway mechanism's rotating rollers are in close contact with the cable, reducing fatigue damage caused by cable shaking, extending the cable's service life, and preventing safety accidents caused by cable damage, providing reliable protection for caisson towing operations, reducing operating costs and safety hazards.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-9 The present invention provides the following technical solution: a fixing structure for a caisson towing device.

[0039] Example 1: To address the issue that current fixed structures on the market encounter various problems when dragging cables using tow wheels, such as changes in the cable's stress point during position adjustments, and even cable misalignment after multiple adjustments, please refer to the attached document. Figure 1 - Appendix Figure 3 and attached Figure 5 - Appendix Figure 7The system includes a fixed steel frame 1, a back plate 2 fixed to the back of the fixed steel frame 1, a U-shaped fitting block 3 embedded in the inner side of the back plate 2, and a locking connection between the U-shaped fitting block 3 and the back plate 2 via a locking bolt 4; a base plate 7 fixed to the bottom of the fixed steel frame 1, and drive motors 8 fixedly installed on the back of both sides of the base plate 7, with the output end of the drive motor 8 connected to one end of a locking mechanism, the locking mechanism achieving the clamping action of the actuator end through the threaded transmission of the bidirectional threaded rod 9 and the threaded connecting sleeve 10, the actuator end of the locking mechanism acting on the outside of the cable; a mating roller 5 rotatably arranged inside the fixed steel frame 1, a limit mating block 6 fixed at the end of the mating roller 5 near the inner side of the fixed steel frame 1, a cable passing through the limit mating block 6 and the inner side of the mating roller 5; the locking mechanism includes a bidirectional threaded rod 9 fixedly connected to the output end of the drive motor 8, the bidirectional threaded rod 9... Both ends of the threaded rod 9 are threadedly connected to threaded connecting sleeves 10. The bottom of the threaded connecting sleeve 10 is rotatably connected to a movable rod 11. The bottom of the movable rod 11 is rotatably connected to the top inner side of the connecting shaft 12. The bottom of the connecting shaft 12 is fixed to the top center of the pressure plate 13 by bolts. A slider 14 is fixed to the outside of the pressure plate 13. The outside of the slider 14 is slidably disposed on the inner side of the guide groove 17. The guide groove 17 is opened on the inner side of the base plate 7. A fixing plate 16 is also fixed inside the base plate 7. Several sets of locking pins 15 are fixed on the corresponding side of the fixing plate 16 and the pressure plate 13. The upper and lower sets of locking pins 15 are staggered. The outside of the fixing plate 16 acts on the outside of the cable. The size of the fixing plate 16 is the same as that of the pressure plate 13. The pressure plate 13 forms a sliding structure between the slider 14 and the inner side of the guide groove 17.

[0040] First, the U-shaped fitting block 3 is embedded inside the back plate 2, and the U-shaped fitting block 3 is locked to the back plate 2 with the locking bolt 4, so that the fixed steel frame 1 forms a stable foundation connection with the caisson through the back plate 2, preventing the overall structure from shifting; then, the cable is passed through the mating roller 5 and the limiting mating block 6 inside the fixed steel frame 1. The mating roller 5 supports and guides the cable, while the limiting mating block 6 restricts the lateral movement of the cable, ensuring that the cable extends along the fixed path to the locking mechanism at the bottom plate 7; the drive motor 8 on the back of the left and right sides of the bottom plate 7 is activated. The output end of the drive motor 8 drives the bidirectional threaded rod 9 to rotate. With the threads in opposite directions, the threaded connecting sleeve 10 on the outer side moves relative to the rod body. The threaded connecting sleeve 10 pushes the connecting shaft 12 downward through the movable rod 11 connected to the bottom, thereby driving the pressure plate 13 at the bottom of the connecting shaft 12 to move closer to the cable. At the same time, the slider 14 on the outer side of the pressure plate 13 slides along the guide groove 17 on the inner side of the base plate 7 to ensure the stability of the movement trajectory of the pressure plate 13. Finally, the pressure plate 13 cooperates with the fixing plate 16 inside the base plate 7, and clamps the cable through the misaligned locking pins 15 on the opposite surfaces of the two, increasing the friction between the cable and the components, preventing the cable from shifting due to changes in the force point caused by position adjustment, and achieving reliable cable fixation.

[0041] Example 2: To reduce the possibility of offset during subsequent dragging, please refer to the attached document. Figure 1 Appendix Figure 2 Appendix Figure 4 Appendix Figure 5 Appendix Figure 8 and attached Figure 9 The anti-sway mechanism acts on the outside of the cable. The anti-sway mechanism operates synchronously with the locking mechanism through the meshing of a fixed rack 18 and a rotating gear 19. The rotating roller 24 of the anti-sway mechanism provides elastic clamping to the cable to buffer the swaying force. The anti-sway mechanism includes a fixed rack 18 fixed to one side of the slider 14. A rotating gear 19 is meshed with the outer side of the fixed rack 18. A rotating connecting sleeve 20 is fixed at the center of the rotating gear 19. A threaded tube 21 is threadedly connected to the inner side of the rotating connecting sleeve 20. The other end of the threaded tube 21 is fixed to the support frame 2. On one side of the support frame 22, a rotating roller 24 is rotatably mounted on the outer side of the support frame 22. Two sets of guide rods 23 are fixed on the rear side of the support frame 22. The guide rods 23 are symmetrically arranged about the transverse center of the support frame 22. The outer side of the guide rods 23 is slidably mounted inside the drive motor 8. The outer side of the rotating connecting sleeve 20 is rotatably mounted inside the drive motor 8. The support frame 22 forms a sliding structure with the inside of the drive motor 8 through the guide rods 23. An anti-slip pad is attached to the inner wall of the U-shaped bonding block 3. The anti-slip pad is fixedly connected to the U-shaped bonding block 3 by adhesive.

[0042] When the locking mechanism is activated, the pressure plate 13 drives the outer slider 14 to move along the guide groove 17. The fixed rack 18 fixed on one side of the slider 14 moves synchronously with the slider 14. The fixed rack 18 meshes with the rotating gear 19 on the outside, which drives the rotating gear 19 and the rotating connecting sleeve 20 fixed at the center to rotate. The inner side of the rotating connecting sleeve 20 is threaded with the threaded tube 21, converting the rotational motion into linear motion, which pushes the support frame 22 connected to the other end of the threaded tube 21 to move. The two sets of guide rods 23 on the rear side of the support frame 22 slide along the inside of the drive motor 8 to ensure that the support frame 22 moves smoothly, so that the rotating roller 24 on the outer side of the support frame 22 accurately approaches and fits the cable. The rotating roller 24 can rotate adaptively with the slight sway of the cable, forming an elastic clamp on the cable, buffering the shaking force during the dragging process, and reducing the deviation of the cable caused by the sway. At the same time, the anti-slip pad on the inner wall of the U-shaped fitting block 3 increases the friction with the caisson, further improving the connection stability between the fixed steel frame 1 and the caisson, and jointly ensuring that the cable is not easily deviated during the dragging operation.

[0043] A fixing structure for a caisson towing device is disclosed, and a fixing method for the caisson towing device is also disclosed, the specific method being as follows:

[0044] S1: Embed the U-shaped fitting block 3 into the inner side of the back plate 2, and lock the U-shaped fitting block 3 to the back plate 2 through the locking bolt 4, so that the fixed steel frame 1 forms a basic fixation through the back plate 2, the sunken box and the U-shaped fitting block 3;

[0045] S2: Pass the cable through the inside of the fixed steel frame 1 between the mating roller 5 and the limiting mating block 6, so that the cable extends along the outside of the mating roller 5 to the position of the locking mechanism on the base plate 7;

[0046] S3: Start the drive motors 8 on the back of the left and right sides of the base plate 7. The output end of the drive motor 8 drives the locking mechanism to run, so that the execution end of the locking mechanism moves closer to the outside of the cable and fits against the cable, thus achieving the initial fixation of the cable.

[0047] S4: During the operation of the locking mechanism, the anti-sway mechanism linked to its outer side moves synchronously. The outer side of the anti-sway mechanism moves closer to the outer side of the cable as the locking mechanism moves, until the outer side of the anti-sway mechanism is in contact with the outer side of the cable.

[0048] S5: After the caisson towing operation is completed, start the drive motor 8 in reverse to drive the locking mechanism execution end away from the cable. The anti-sway mechanism resets in conjunction with the locking mechanism. Then, remove the cable from between the mating roller 5 and the limit mating block 6 to complete the fixation release.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
