Description

Technical Field

[0001] This utility model relates to the field of bridge inspection support technology, specifically to a bridge underwater structure inspection support. Background Technology

[0002] As the main load-bearing structure of a bridge, the piers must be kept in good condition. Underwater piers are subject to long-term scouring by water flow, corrosion by chemicals in the water, and a series of effects caused by human factors, which can lead to cracking, corrosion, and damage. In severe cases, the steel bars inside the concrete may be exposed, which can seriously affect the safety of the underwater structure of the bridge. Therefore, it is necessary to inspect the underwater structure of the piers.

[0003] Existing methods for inspecting underwater bridge piers typically involve erecting a support frame on the pier and using a lifting mechanism on the frame to move the inspection equipment downwards. Current lifting mechanisms usually employ ropes or telescopic rods. While ropes can be wound up and lowered to different depths, their flexible lifting makes the equipment susceptible to swaying due to water flow, affecting the inspection results. Ropes, on the other hand, provide rigid lifting and prevent swaying, but their lifting distance is limited and cannot meet the requirements for inspecting bridge piers in deeper waters. Therefore, this invention proposes a support frame for inspecting underwater bridge structures. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge underwater structure inspection bracket in order to solve the problems in the background art.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figures 1-10 As shown, an embodiment of this utility model provides a bridge underwater structure inspection bracket, comprising:

[0032] Several arc-shaped plates 1 are arranged to form a ring and are fitted onto the bridge pier. A screw rod 2 is threaded through the arc-shaped plate 1. An arc-shaped block 3 is rotatably connected to the free end of the screw rod 2. Preferably, both ends of the arc-shaped plate 1 are provided with ear plates with through holes. Several arc-shaped plates 1 are arranged to surround the bridge pier and are sequentially spliced ​​to form a ring. The arc-shaped plates 1 are then fixed by the cooperation of screws and nuts. After several arc-shaped plates 1 are arranged and fixed into a ring, the screw rod 2 is twisted to rotate and move, thereby causing the arc-shaped block 3 to press against the surface of the bridge pier. Several arc-shaped blocks 3 press against and fix the bridge pier, thereby fixing the ring on the bridge pier.

[0033] The movable frame 4 is rotatably mounted on a circular ring. The circular ring is equipped with a driving component 5 for driving the movable frame 4 to rotate. Preferably, both the upper and lower sides of the arc plate 1 are constructed with arc rails. The movable frame 4 is provided with arc rail grooves. The arc rails are slidably inserted into the arc rail grooves. When several arc plates 1 are enclosed to form a circular ring, several arc rails on the same side are spliced ​​together to form a circular rail. The movable frame 4 can rotate along the circular rail. By driving the movable frame 4 to rotate through the driving component 5, the movable frame 4 can rotate around the bridge pier in a circular motion.

[0034] The lifting rod 6 is connected to the movable frame 4. The lifting rod 6 includes several vertical rods 601 spliced ​​together end to end. A rack 602 is fixed on one side of each vertical rod 601. A first shaft 7 is rotatably mounted on the movable frame 4. A first gear 8 that meshes with the teeth of the rack 602 is fixed on the first shaft 7. A first motor 9 is connected to the end of the first shaft 7 and mounted on the movable frame 4. In actual use, the number of vertical rods 601 can be increased or decreased according to the depth of the water. Several vertical rods 601 are spliced ​​together to form a lifting rod 6. The length of the lifting rod 6 is adapted to the depth of the water. It should be noted that the racks 602 on two adjacent vertical rods 601 can be effectively spliced ​​together to form a long rack. When the first motor 9 does work, its output shaft drives the first shaft 7 to rotate. Through the meshing of the teeth of the rack 602 with the first gear 8, the lifting rod 6 can be raised and lowered.

[0035] Mounting plate 10 is set at the bottom of lifting rod 6 and is used to install detection equipment. When inspecting the bridge pier, the detection equipment is installed on mounting plate 10. The movable frame 4 is driven to rotate by driving component 5, which can drive the detection equipment to move around the bridge pier. At the same time, the first motor 9 drives the lifting rod 6 to rise and fall, which can drive the detection equipment to rise and fall, and can carry out comprehensive inspection of the underwater parts of the bridge pier.

[0036] In this scheme, the testing equipment is installed on the mounting plate 10. The driving component 5 drives the movable frame 4 to rotate in a circle. The first motor 9 can drive the lifting rod 6 to rise and fall, thereby enabling the testing equipment to rotate and rise and fall, thus conducting a comprehensive inspection of the bridge pier. The lifting rod 6 is formed by sequentially splicing several vertical rods 601. Its number can be increased or decreased according to the depth of the water area to meet the testing needs of water areas of different depths. At the same time, the lifting rod 6 formed by splicing vertical rods 601 is rigid, so that the testing equipment will not sway due to water flow, thus ensuring the testing results.

[0037] like Figure 3 and Figure 4As shown, the specific structure of the driving component 5 of this utility model is disclosed. The driving component 5 includes a second shaft 501 rotatably mounted on the movable frame 4, several arc-shaped plates 1 each fixed with an arc rack 502, the several arc racks 502 forming a circular toothed ring, a second gear 503 fixed on the second shaft 501 that meshes with the teeth of the arc racks 502, and a second motor 504 mounted on the movable frame 4 connected to the end of the second shaft 501. The second motor 504 performs work, and its output shaft drives the second shaft 501 to rotate, thereby driving the second gear 503 to rotate. Through the meshing of the teeth of the second gear 503 with the circular toothed ring, the movable frame 4 is driven to rotate.

[0038] like Figure 10 As shown, a further technical solution for splicing vertical rods 601 is disclosed. One end of the vertical rod 601 is provided with a slot 11, and the other end is constructed with a plug block 12 that is inserted into the slot 11. A through hole 13 is provided on the plug block 12. A plug rod 14 that is inserted into the through hole 13 is threaded through the vertical rod 601. The plug block 12 at the end of one vertical rod 601 is movably inserted into the slot 11 at the end of another vertical rod 601. Then, the plug rod 14 is twisted and rotated to move it, so that the plug rod 14 is inserted into the through hole 13, thereby achieving the function of fixing the two adjacent vertical rods 601. At the same time, it can also ensure that the racks 602 on the two adjacent vertical rods 601 are effectively connected, and ensure that the second gear 503 can effectively mesh and transition from the two adjacent racks 602.

[0039] like Figure 9 As shown, a further technical solution for the lifting rod 6 of this utility model is disclosed. A worm gear 15 is fixedly mounted on the first shaft 7, and a worm 16 that meshes with the worm gear 15 is fixedly mounted on the output shaft of the first motor 9. When the first motor 9 does work, its output shaft drives the worm 16 to rotate. Through the meshing of the worm 16 and the worm gear 15, the first shaft 7 is driven to rotate. By adding the worm 16 and the worm gear 15, the first motor 9 is not directly connected to the first shaft 7. Utilizing the meshing characteristics of the worm 16 and the worm gear 15 (the worm 16 can drive the worm gear 15 to rotate, but the worm gear 15 cannot drive the worm 16 to rotate in reverse), the first motor 9 can be overload protected to ensure the stability of the lifting rod 6.

[0040] like Figure 1 , Figure 7 and Figure 8As shown, the present invention discloses a further technical solution for detection. Two support rods 17 are provided on one side of the mounting plate 10, and scrapers 18 are connected to the ends of the two support rods 17. The scrapers 18 are connected to the mounting plate 10 through the support rods 17. When the mounting plate 10 rotates or rises and falls, the scrapers 18 scrape the surface of the pier, which can remove impurities such as algae and shells attached to the surface of the pier, so that the detection equipment can better detect the surface of the pier.

[0041] like Figure 8 As shown, a further technical solution for the scraper 18 of this utility model is disclosed. Two sockets 19 are provided on the mounting plate 10, and two support rods 17 are slidably inserted into the two sockets 19 respectively. A spring 20 is connected between the inner wall of the socket 19 and the support rod 17. By providing sockets 19 on the mounting plate 10, the support rod 17 is movably inserted into the sockets 19 and connected to the spring 20. Under the influence of the elastic force of the spring 20, the scraper 18 can effectively contact and overlap with the surface of the bridge pier, so that the surface of the bridge pier can be effectively scraped and cleaned, thereby ensuring the test results.

[0042] like Figure 7 and Figure 8 As shown, the present invention discloses a further technical solution for the scraper 18. The scraper 18 includes a fixing plate 1801 fixedly mounted on the ends of two support rods 17. A rectangular frame 1802 is connected between the two fixing plates 1801. Preferably, the rectangular frame 1802 is a plastic frame with a certain toughness and deformation capability. Since the outer wall of the bridge pier is an arc-shaped surface, the scraper 18 is composed of the fixing plate 1801 and the rectangular frame 1802. The two fixing plates 1801 are respectively resisted by the elastic force of two springs 20, which can force the rectangular frame 1802 to produce a certain degree of deformation. This can effectively bring the rectangular frame 1802 into contact with the surface of the bridge pier, ensuring the scraping and cleaning effect. In actual use, after the detection equipment is installed on the mounting plate 10, it corresponds exactly to the hollow position in the center of the rectangular frame 1802, so that the rectangular frame 1802 can effectively clean the surface of the bridge pier without obstructing the detection.

[0043] like Figure 4 As shown, the present invention discloses a further technical solution for the arc-shaped block 3. The inner wall of the arc-shaped block 3 is provided with a rubber pad 21, and the rubber pad 21 is constructed with anti-slip ridges. By providing a rubber pad 21 and constructing anti-slip ridges on the inner wall of the arc-shaped block 3, the contact friction between the arc-shaped block 3 and the surface of the bridge pier can be increased, thereby improving the fixing effect on the arc-shaped plate 1, and further improving the stability of the entire support after it is erected.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
