[0031] This embodiment aims to provide a rapid underwater concrete structure repair tool, whose main function is to replace manual underwater operations, thereby accelerating the overall repair speed of underwater concrete piers.
[0032] Reference Figure 1 , Figure 2 and Figure 4 The system includes: a support, a rotating ring 4, and a ring-shaped climbing frame 6. The support includes an inner ring seat 1 and an outer ring seat 2. The inner ring seat 1 surrounds and is fixed to the upper exterior of the pier. Four or more connecting pipes 3 are welded between the inner ring seat 1 and the outer ring seat 2. The four connecting pipes 3 are evenly distributed along the circumference. A positioning pin 10 is fitted inside the connecting pipe 3. The positioning pin 10 is a threaded rod. The surface of the pier has four positioning holes that are adapted to the positioning pins 10. These positioning holes are threaded holes. The surfaces of the outer ring seat 2 and the inner ring seat 1 are provided with through holes for the positioning pins 10 to pass through. Holes are provided so that the positioning pin 10 can pass through the outer ring seat 2, the connecting pipe 3 and the inner ring seat 1 simultaneously and be screwed into the corresponding positioning hole, so that the positioning pin 10 is threaded into the positioning hole, and the screw head of the positioning pin 10 is attached to the outer side of the outer ring seat 2, thereby stabilizing and fixing the entire support to the pier. The positioning hole and through hole are not shown in the figure. The inner ring seat 1 and the outer ring seat 2 are both vertical flat rings to widen them vertically, which is more conducive to the installation of the connecting pipe 3 and the positioning pin 10, and the diameter of the screw head of the positioning pin 10 will not exceed the vertical width of the outer ring seat 2.
[0033] Reference Figures 1-4The rotating ring 4 is located above the support and encircles the outside of the pier. Four or more traveling wheels 5 are rotatably mounted below the rotating ring 4. Each traveling wheel 5 is rotatably mounted between two support plates. The top of the support plate is welded to the bottom of the rotating ring 4. The four traveling wheels 5 are evenly distributed along the circumference of the rotating ring 4. The traveling wheels 5 are located on the top of the outer ring seat 2 and are supported by the outer ring seat 2, allowing the traveling wheels 5 to move along the circumference of the outer ring seat 2, greatly reducing the rotational resistance of the rotating ring 4. Four or more hoists 11 are distributed along the circumference of the top of the rotating ring 4. The frame of the hoist 11 is fixed on the rotating ring 4. The hoist 11 is an electric winch. The switching circuits of the four hoists 11 are connected in series so that they can be started simultaneously and work together. The ropes of the hoists 11 hang down to connect to the lifting device below. The rotating ring 4 is a horizontally flat ring to widen it laterally, which is more conducive to installing the hoists 11 on the top of the rotating ring 4. If necessary, a notch can be set on the outer edge of the rotating ring 4 at the position corresponding to the rope to avoid hindering the movement of the rope.
[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The circular climbing frame 6 is suspended below the support and surrounds the outside of the pier. The circular climbing frame 6 is spaced apart from the pier. Four or more U-shaped hanging plates 7 are fitted on the outside of the circular climbing frame 6. The hanging ropes are fixedly connected to the top of the corresponding hanging plate 7. The top of the hanging plate 7 is provided with a hanging ring for connecting the rope. So when the rotating ring 4 rotates, the hanging plate 7 will be pulled by the rope to move along the circumference of the circular climbing frame 6. The bottom of the frame is rotatably installed with a support wheel 12, so that the support wheel 12 is inverted on the bottom of the circular climbing frame 6, so that the support wheel 12 moves along the circumference of the circular climbing frame 6. The circumferential displacement is greatly reduced by the support rollers 12; each of the four hanging plates 7 is horizontally equipped with a high-pressure nozzle 8. The high-pressure nozzle 8 uses a fan-shaped nozzle, and the water curtain it sprays is horizontal and covers a wider area, so that the high-pressure nozzle 8 is oriented towards the pier. The high-pressure nozzle 8 has a threaded section in the middle so that the high-pressure nozzle 8 is threadedly fitted with the top of the hanging plate 7, which is conducive to positioning the high-pressure nozzle 8. The tail ends of the four high-pressure nozzles 8 are used to connect water pipes, which are then connected to the pump body. The water pipes and the pump body are not shown in the figure.
[0035] Reference Figure 1 , Figure 2 and Figure 5The inner side of the annular climbing frame 6 is equipped with four or more climbing wheels 9, which are evenly distributed around the pier and abut against the surface of the pier, allowing the climbing wheels 9 to move along the height direction of the pier. The distance between the climbing wheels 9 and the annular climbing frame 6 can be adaptively adjusted according to the diameter of different piers. Specifically, a rectangular support column 13 is provided between the climbing wheels 9 and the annular climbing frame 6. The climbing wheels 9 are rotatably installed at one end of the support column 13, and the other end of the support column 13 passes through the annular climbing frame 6 and is welded to an anti-detachment plate 14. The diameter of the anti-detachment plate 14 is larger than the diameter of the support column 13. The external fitting of the support column 13 is limited. Positioning plate 15 and limiting plate 15 are located inside the annular climbing frame 6, and a spring 16 is provided between the limiting plate 15 and the annular climbing frame 6. The spring 16 is sleeved on the outside of the support column 13. When the diameter of the pier column is too large, the pier column will squeeze the climbing wheel 9 outward during installation to reduce the distance between the climbing wheel 9 and the annular climbing frame 6, ensuring that all four climbing wheels 9 can contact the surface of the pier column. The climbing wheel 9 can greatly reduce the resistance of the annular climbing frame 6 moving up and down, and at the same time, it can also prevent the high-pressure nozzle 8 from colliding with the surface of the pier column. The annular climbing frame 6 is a vertical flat ring, which is widened in the vertical direction, which is beneficial to the installation of the support column 13.
[0036] In this embodiment, a hanging plate 7 is set between every two adjacent climbing wheels 9, and the distance between adjacent climbing wheels 9 is the moving distance of a single hanging plate 7.
[0037] In this embodiment, both the traveling wheel 5 and the supporting wheel 12 are rail wheels with a concave center, which provides strong stability during movement.
[0038] In this embodiment, the inner ring seat 1, outer ring seat 2, rotating ring 4, and annular climbing frame 6 are all arranged in half. The half-ring joint of the inner ring seat 1 and the outer ring seat 2 does not require additional fasteners because the positioning pin 10 fixes the inner ring seat 1 and the outer ring seat 2 to the pier column, and at the same time fixes their shape. That is to say, the inner diameter of the inner ring seat 1 should be designed to match the diameter of the pier column. However, the half-ring joint of the rotating ring 4 and the annular climbing frame 6 needs to be fixed by additional bolts.
[0039] During installation, first, the support ring is placed on the designated position above the pier. Then, the support is fixed to the pier using the positioning pin 10. Next, a rotating ring 4 is installed above the support, so that the rotating ring 4 is placed around the outside of the pier. The rotating ring 4 needs to meet the conditions for rotation, so the inner diameter of the rotating ring 4 is larger than the diameter of the pier to avoid contact between the rotating ring 4 and the surface of the pier. The hoist 11 on the rotating ring 4 is pre-installed and fixed. The next step is to install a ring-shaped climbing frame 6 below the support and connect the rope of the hoist 11 to the hanging plate 7 on the ring-shaped climbing frame 6. The installation is now complete.
[0040] In use, the four hoists 11 connected in series are started simultaneously. The ring climbing frame 6 is lowered into the water by raising and lowering the ropes. At the same time, the high-pressure nozzles 8 spray a horizontal pressure water curtain towards the pier. During this period, the workers can control the rotating ring 4 on the work platform to change the spray position of the high-pressure nozzles 8 to ensure that the surface of the pier is fully roughened, thus ensuring the quality of the repair work. After roughening is completed, the tool can be disassembled and removed in sequence.
[0041] The tool provided in this embodiment for underwater concrete pier repair work can replace manual roughening of the pier surface, significantly improving work efficiency and quality, greatly accelerating the pier repair speed, and allowing workers to control the tool to roughen the pier surface without going into the water, reducing the risk of underwater operations.
[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
