Description

Technical Field

[0001] This application relates to the field of bridge pier inspection, and in particular to an inspection vessel for inspecting bridge piers. Background Technology

[0002] Currently, bridge piers are an important component of bridge structures, and their safety and reliability directly affect the operational safety of the entire bridge. Therefore, regular inspections of bridge piers are essential.

[0003] In existing technologies, the frequency of inspections during the service life of a bridge is determined based on the condition of the piers and the results of inspections. Generally, a visual inspection and dimensional measurement should be conducted annually, a concrete strength test and a steel reinforcement corrosion test should be performed every two years, and a non-destructive test should be conducted every five years. For visual inspections, a combination of visual inspection and magnification is used to comprehensively examine the surface of the pier. For dimensional inspections, measuring tools such as steel rulers and calipers are used to measure the dimensions of the pier. For non-destructive testing, an ultrasonic testing instrument is used to inspect the interior of the pier. Based on parameters such as the propagation speed and amplitude of ultrasonic waves in the concrete, the presence of internal defects in the pier is determined.

[0004] Regarding the aforementioned existing technologies, when inspecting cross-sea bridges far from land, it is usually necessary for staff to travel by boat to get close to the bridge piers for inspection. The sea surface has waves, and the staff are subject to significant swaying during the inspection process, which not only affects the progress of the inspection work but also poses a significant danger to the staff. There is an urgent need for improvement. Summary of the Invention

[0005] To reduce the swaying of the vessel, improve the convenience of inspecting bridge piers, and ensure the safety of personnel during the inspection process, this application provides an inspection vessel for inspecting bridge piers.

[0006] The technical solution for an inspection vessel used to inspect bridge piers provided in this application is as follows: The structure includes a hull, on which a telescopic support arm is rotatably connected. The hull is equipped with a first driving component for rotating the telescopic support arm. A passenger seat is provided at the end of the telescopic support arm away from the hull. Multiple lifting rods are connected to one side of the hull for lifting. A second driving component is provided on the hull for lifting the lifting rods. An overlapping plate is provided at the top of the lifting rod, and the overlapping plate overlaps with the bridge pier.

[0007] By adopting the above technical solution, a flat surface is formed on the bridge pier. After the hull approaches the bridge pier, the second driving component locks the overlapping plate to the bridge pier, thereby achieving the purpose of fixing the inspection window. In conjunction with the use of a telescopic support arm, it allows the staff to inspect the bridge pier more stably and safely, reduces the amplitude of ship swaying, improves the convenience of inspecting the bridge pier, and ensures the safety of the staff during the inspection process.

[0008] Preferably, a rubber fender is provided on the side of the hull near the lifting boom, and the rubber fender is used to abut against the bridge pier.

[0009] By adopting the above technical solution, the rubber fenders can achieve the purpose of buffering during use, reducing the damage of the piers to the hull. Furthermore, the rubber fenders and the overlapping plates can work together to achieve the purpose of mutual compression, thereby enabling the hull to be fixed more stably and improving the stability of the hull during use.

[0010] Preferably, the hull is provided with a drone mount, the drone mount is provided with a drone, and the drone mount is provided with a wireless charging block.

[0011] By adopting the above technical solution, staff can more conveniently inspect bridge piers using drones, thus improving the ease of inspection.

[0012] Preferably, the hull has a manned compartment, and a manned seat is installed in the manned compartment.

[0013] By adopting the above technical solutions, the manned cavity can make the operation of the ship more stable for the staff, improve the safety of using the inspection ship, and, together with the manned seat, make the staff more comfortable, thus improving the comfort of using the inspection ship.

[0014] Preferably, the bottom of the hull is provided with multiple keels for maintaining balance, and a rubber cover is provided on the side of the keel near the overlapping plate. A negative pressure cavity is formed inside the rubber cover, and a connecting hole is opened on the hull to communicate with the negative pressure cavity. A sealing plug is inserted into the connecting hole.

[0015] By adopting the above technical solution, during use, the rubber cover abuts against the bridge pier in the water. Through the deformation of the negative pressure chamber, the purpose of adsorbing and fixing the hull can be achieved. Furthermore, since the part of the bridge pier in the water is in the water for a long time, the surface of the bridge pier can be made smoother, reducing the occurrence of the rubber cover detaching from the bridge pier. When it is necessary to leave, the sealing plug can be removed, thereby making the negative pressure chamber lose its negative pressure effect, improving the convenience of the inspection vessel leaving.

[0016] Preferably, the telescopic support arm consists of two hinged first support arms and a second telescopic arm, the carrier is installed at the end of the second telescopic arm, the first support arm is provided with a third driving member for controlling the rotation of the first support arm and the second telescopic arm, a support rotating seat is provided between the first support arm and the second telescopic arm, the support rotating seat is provided with a support block, and the support block abuts against the bridge pier.

[0017] By adopting the above technical solution, in the process of using some bridge piers, which are quite high, the center of gravity will rise when the telescopic support arm is raised. By using the first support arm in conjunction with the support pivot to support the support block on the plane or side wall of the bridge pier, a secondary fixing purpose can be achieved, thereby reducing the tilting of the telescopic support arm and improving the convenience of bridge pier inspection.

[0018] Preferably, a vacuum chamber is provided on the side of the support block away from the support rotating seat, and a telescopic arc cavity is provided inside the support rotating seat. The telescopic arc cavity is aligned with the rotation axis of the first support arm. Both the first support arm and the second telescopic arm are provided with telescopic sliders that slide and cooperate with the telescopic arc cavity. A telescopic airbag connected to the vacuum chamber is provided inside the telescopic arc cavity. The two ends of the telescopic airbag are mounted on two telescopic sliders, which are spaced apart from each other to draw air from the vacuum chamber.

[0019] By adopting the above technical solution, during use, the first support arm abuts the support block against the bridge pier, and then the second telescopic arm is rotated to raise it and pull the telescopic airbag, so that the support block can be more stably fixed to the bridge pier, improving the stability of the support block and enhancing the safety of the staff.

[0020] Preferably, two hinge seats are symmetrically arranged on one side of the hull, and clamping seats are rotatably connected to the hinge seats. Multiple lifting rods are installed on the two clamping seats. The two clamping seats are tilted upwards in a direction away from the hull. A fourth driving member is provided on the hull for driving the two clamping seats to rotate. The two clamping seats are used to clamp the bridge pier.

[0021] By adopting the above technical solution, during use, the pier is first squeezed by two clamping seats to initially fix the hull, and then the overlapping plates are used to lock it again, which can improve the firmness of the hull fixation.

[0022] Preferably, counterweight sliding cavities are provided on both sides of the two clamping seats that are close to each other. The counterweight sliding cavities are inclined downward along the direction close to the hull. A counterweight block is slidably connected in the counterweight sliding cavity. When the two clamping seats are close to each other, the counterweight block slides towards the hull. When the two clamping seats are far apart, the counterweight block abuts against the side wall of the pier. During the contraction of the two clamping seats, the counterweight block is pulled away from the hull.

[0023] By adopting the above technical solution, during use, the bottom of the telescopic support arm is balanced with the counterweight, which can reduce the tilt of the hull and improve the stability of the hull. During normal operation, the counterweight moves closer to the hull, thereby bringing the counterweight closer to the center position and improving the stability of the hull.

[0024] Preferably, abutting blocks are installed on the two sides of the two counterweights that are close to each other, and the abutting blocks are rotatably connected to the counterweights.

[0025] By adopting the above technical solution, the clamping block can be used to fix the pier more firmly during use, thereby improving the stability of the ship's fixation.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The bridge pier has a flat surface. After the hull approaches the bridge pier, the second drive component locks the overlapping plate to the bridge pier, thereby fixing the inspection window. In conjunction with the use of the telescopic support arm, the staff can inspect the bridge pier more stably and safely, reduce the amplitude of the ship's sway, improve the convenience of inspecting the bridge pier, and ensure the safety of the staff during the inspection process. 2. During use, the rubber cover abuts against the bridge pier in the water. Through the deformation of the negative pressure chamber, it can achieve the purpose of adsorbing and fixing the hull. Furthermore, the part of the bridge pier in the water, due to being in the water for a long time, can make the surface of the bridge pier smoother, reducing the occurrence of the rubber cover detaching from the bridge pier. When it is necessary to leave, the sealing plug is removed, which can make the negative pressure chamber lose its negative pressure effect, improving the convenience of the inspection vessel leaving. 3. During use, the pier is first pressed by two clamping seats to initially fix the hull, and then the overlapping plates are used to lock it again, which can improve the firmness of the hull fixation.

[0028] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0029] This application discloses an inspection vessel for inspecting bridge piers.

[0030] Example 1; Reference Figure 1 An inspection vessel for inspecting bridge piers includes a hull 1. A telescopic support arm 3 is rotatably connected to the hull 1. The telescopic support arm 3 is a telescopic boom, and by controlling its extension and retraction length, the inspection area can be expanded. A first drive component 2, which is a first drive cylinder, is installed on the hull 1 to drive the telescopic support arm 3 to rotate. A passenger seat 4 is installed on the side of the telescopic support arm 3 away from the hull 1 for carrying personnel and inspection equipment. Multiple lifting rods are connected to one side of the hull 1 for lifting. A second drive component 5, which is a second drive cylinder, is installed on the hull 1 to drive the lifting rods to raise and lower. An overlapping plate 6 is installed on the top of the lifting rods, which overlaps with the bridge pier to fix the hull 1 and improve the safety of personnel during the inspection process.

[0031] A rubber fender 7 is installed on the side of the hull 1 near the lifting mast. The rubber fender 7 is made of rubber material and is used to abut the bridge pier.

[0032] The implementation principle of an inspection vessel for inspecting bridge piers according to an embodiment of this application is as follows: a flat surface is formed on the bridge pier. After the hull 1 approaches the bridge pier, the overlapping plate 6 is snapped onto the bridge pier by the second driving component 5, thereby achieving the purpose of fixing the inspection window. In conjunction with the use of the telescopic support arm 3, the staff can inspect the bridge pier more stably and safely, reduce the amplitude of the vessel's swaying, improve the convenience of inspecting the bridge pier, and ensure the safety of the staff during the inspection process.

[0033] Example 2; Reference Figure 2 The difference between this embodiment and Embodiment 1 is that a drone mount is installed on the hull 1, a drone 9 is installed on the drone mount, and a wireless charging block 10 is fixed on the drone mount. A manned cavity 11 is provided on the hull 1, and a manned seat 8 is installed on the manned cavity 11.

[0034] The bottom of the hull 1 is equipped with multiple keels for balance. A rubber cover 13 is fixed on the side of the keel near the overlapping plate 6. The rubber cover 13 is C-shaped and made of rubber material. A negative pressure chamber 14 is formed inside the rubber cover 13. A connecting hole connected to the negative pressure chamber 14 is opened on the bed. A sealing plug 12 is inserted into the connecting hole.

[0035] The implementation principle of Example 2 is as follows: During use, the rubber cover 13 abuts against the bridge pier located in the water. Through the deformation of the negative pressure chamber 14, the purpose of adsorbing and fixing the hull 1 can be achieved. Furthermore, the part of the bridge pier in the water, due to being in the water for a long time, can make the surface of the bridge pier smoother, reducing the occurrence of the rubber cover 13 detaching from the bridge pier. When it is necessary to leave, the sealing plug 12 is removed, thereby making the negative pressure chamber 14 lose its negative pressure function, improving the convenience of the inspection vessel leaving.

[0036] Example 3; Reference Figure 4 The telescopic support arm 3 consists of two hinged first support arms 23 and a second telescopic arm 15. A carrier seat 4 is installed at the end of the second telescopic arm 15. A fifth drive cylinder is installed on the hull 1 to drive the rotation of the first support arm 23. A third drive component 22, which is a third drive cylinder, is installed on the first support arm 23 to control the rotation of the first support arm 23 and the second telescopic arm 15. A support pivot 16 is installed between the first support arm 23 and the second telescopic arm 15, and a support block 17 is installed on the support pivot 16, which abuts against the bridge pier.

[0037] A vacuum chamber 18 is provided on the side of the support block 17 away from the support rotating seat 16. A telescopic arc cavity 21 is provided inside the support rotating seat 16. The telescopic arc cavity 21 is aligned with the rotation axis of the first support arm 23. Telescopic sliders 20 that slide and cooperate with the telescopic arc cavity 21 are installed on both the first support arm 23 and the second telescopic arm 15. A telescopic airbag 19 that communicates with the vacuum chamber 18 is installed inside the telescopic arc cavity 21. The two ends of the telescopic airbag 19 are installed on the two telescopic sliders 20. The two telescopic sliders 20 are far apart from each other and are used to draw air from the vacuum chamber 18.

[0038] Two hinge seats are symmetrically installed on one side of the hull 1. Clamping seats 25 are rotatably connected to the hinge seats. Two lifting rods are installed on the two clamping seats 25. The two clamping seats 25 tilt upwards in a direction away from the hull 1. A fourth driving member 24 is installed on the hull 1 to drive the two clamping seats 25 to rotate. The two clamping seats 25 are used to clamp the bridge pier.

[0039] Each of the two clamping seats 25 has a counterweight sliding cavity 28 on both sides near each other. The counterweight sliding cavity 28 is inclined downward along the direction close to the hull 1. A counterweight block 26 is slidably connected inside the counterweight sliding cavity 28. Abutting blocks 27 are respectively installed on both sides of the two counterweight blocks 26 near each other. The abutting blocks 27 are rotatably connected to the counterweight blocks 26. When the two clamping seats 25 are close to each other, the counterweight blocks 26 slide towards the hull 1. When the two clamping seats 25 are far apart from each other and supported on the pier by the abutting blocks 27, the two clamping seats 25 retract, pulling the counterweight blocks 26 away from the hull 1.

[0040] The implementation principle of Example 3 is as follows: During use, the two clamping seats 25 squeeze the pier, thereby initially fixing the hull 1. The bottom of the telescopic support arm 3 is balanced with the counterweight 26, which can reduce the tilt of the hull 1 and improve the stability of the hull 1. During normal operation, the counterweight 26 moves closer to the hull 1, thereby bringing the counterweight 26 closer to the center position and improving the stability of the hull 1. The first support arm 23 abuts the support block 17 against the pier. At this time, the second telescopic arm 15 is rotated to achieve the purpose of raising and pulling the telescopic airbag 19, so that the support block 17 can be more stably fixed to the pier. The stability of the fixed support block 17 improves the safety of the staff.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
