Bridge detection activity platform with good stability

Abstract

This invention discloses a stable bridge inspection platform, relating to the field of bridge inspection technology. It includes a movable mechanism, with a rotating mechanism fixedly connected internally. A connecting mechanism is rotatably connected below the rotating mechanism, and a chassis mechanism is fixedly connected to one side of the connecting mechanism. A guardrail mechanism is fixedly connected to the top of the chassis mechanism. This invention utilizes a combination of a water storage tank, a walking platform, and a movable platform. When seawater enters the walking platform, stepping on the movable platform lowers it, creating a gap between it and the walking platform. Water accumulated in the walking platform flows through this gap into the water storage tank, which stores the water. This prevents seawater from entering the platform when the platform is near the sea, thus avoiding water accumulation and hindering inspection work.

Description

Technical Field

[0001] This invention relates to an active platform, specifically to a bridge inspection technology platform with good stability. Background Technology

[0002] Bridges greatly facilitate people's travel. However, during their use, bridges are subject to natural erosion. To ensure their safety, regular inspections are necessary. To facilitate inspections beneath the bridge, specialized inspection vehicles are required. These vehicles use their mobile platforms to transport inspectors to the bridge's underside for safety checks. However, existing technologies have the following problems:

[0003] 1. In the existing technology, when the inspection platform is working on the platform, if the platform is close to the sea surface, the waves will bring seawater into the platform, causing water to accumulate inside the platform and affecting the inspection work of the inspection personnel.

[0004] 2. In the existing technology, some testing platforms will sway when working under the bridge in strong winds, making it impossible for testing personnel to stand on the platform. This fails to achieve the original purpose of stable work on the platform and reduces the applicability of the testing platform. Therefore, structural innovation is needed to solve the specific problems. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide a stable bridge inspection platform. One objective is to automatically drain seawater that enters the platform, thus addressing the issue of seawater accumulation caused by waves when the platform is near the sea surface, affecting the inspection work. Another objective is to address the problem of platform swaying during strong winds when working under the bridge, making it impossible for inspection personnel to stand on the platform, thereby achieving a stable working environment within the platform.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A stable bridge inspection platform includes an active mechanism, a rotating mechanism fixedly connected inside the active mechanism, a connecting mechanism rotatably connected below the rotating mechanism, a chassis mechanism fixedly connected to one side of the connecting mechanism, and a guardrail mechanism fixedly connected to the top of the chassis mechanism.

[0008] A further improvement of the technical solution of the present invention is that: the chassis mechanism includes a shell, the interior of the shell is provided with a water storage tank, the interior of the water storage tank is provided with a drainage device, the lower part of the drainage device is provided with a water outlet, the outer wall of the water outlet is fixedly connected to the inner wall of the shell, the interior of the drainage device is connected to the interior of the water outlet, the top of the shell is provided with a moving plate, the middle part of the moving plate is provided with a movable plate, the outer wall of the movable plate is movably connected to the inner wall of the shell, and the bottom surface of the movable plate is fixedly connected with a reset spring.

[0009] A further improvement of the technical solution of the present invention is that: the drainage device includes a connecting block, the inside of the connecting block is provided with a drainage pipe, one end of the drainage pipe is connected to a water outlet, a water suction pipe is fixedly connected to the top of the connecting block, water guide plates are provided on both sides of the water suction pipe, and the outer wall of the water guide plate is fixedly connected to the connecting block.

[0010] A further improvement of the technical solution of the present invention is that: the movable plate includes a fixed plate, a convex ball is fixedly connected to the top of the fixed plate, and a drainage groove is provided on the top of the fixed plate.

[0011] A further improvement of the technical solution of the present invention is that: the convex ball includes a spherical shell, a connecting plate is fixedly connected to the inner wall of the spherical shell, a compression spring is fixedly connected to the bottom surface of the connecting plate, a fixing block is fixedly connected to the bottom surface of the compression spring, and the bottom surface of the fixing block is fixedly connected to the inner wall of the spherical shell.

[0012] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0013] 1. This invention provides a bridge inspection platform with good stability. Through ingenious design, it combines a water storage tank, a walking plate, and a movable plate. When seawater enters the walking plate, stepping on the movable plate lowers it, creating a gap between the movable plate and the walking plate. This allows water accumulated in the walking plate to flow into the water storage tank, which stores the water. This avoids the problem of seawater entering the platform when the platform is close to the sea surface, causing water accumulation and affecting the inspection work.

[0014] 2. This invention provides a bridge inspection platform with good stability. By adopting a combination of an outer shell and a water storage tank, the U-shaped shape of the water storage tank causes the water inside to fluctuate with shaking. The fluctuation of the water in the water storage tank counteracts the frequency of wind shaking on the chassis mechanism, forming a wind damper principle, thereby reducing vibration and allowing inspection personnel to work stably on the platform.

[0015] 3. This invention provides a bridge inspection platform with good stability. By using a combination of connecting blocks, suction pipes, and guide plates, when the water level in the water tank exceeds the two sides of the guide plates, it will flow into the area below the suction pipe. When the water level exceeds the top of the suction pipe, the water below the suction pipe will be sucked into the drain pipe through the siphon principle and then discharged from the outlet, saving manpower to clean the water in the water tank.

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] Example 1

[0024] like Figures 1-2As shown, this invention provides a stable bridge inspection platform, including an active mechanism 1. A rotating mechanism 2 is fixedly connected inside the active mechanism 1. A connecting mechanism 3 is rotatably connected below the rotating mechanism 2. A chassis mechanism 4 is fixedly connected to one side of the connecting mechanism 3. A guardrail mechanism 5 is fixedly connected to the top of the chassis mechanism 4. The chassis mechanism 4 includes a shell 41, and a water storage tank 42 is provided inside the shell 41. The platform combines the water storage tank 42, a walking plate 43, and a movable plate 44. This allows water to enter the walking plate 43 when seawater enters it. By stepping on the movable plate 44, a gap is created between the movable plate 44 and the walking plate 43, allowing water to flow from the walking plate 43 into the water storage tank 42. The water storage tank 42 stores the water, preventing seawater from entering the platform when the platform is near the sea surface, thus avoiding water accumulation. To address the issue of interference with testing personnel's work, the water storage tank 42 is equipped with a drainage device 47. By combining the outer shell 41 and the water storage tank 42, the U-shaped shape of the water storage tank 42 causes the water inside to ripple with movement. This ripple counteracts the frequency of wind swaying on the chassis mechanism 4, forming a wind damper principle, thereby reducing vibration and allowing testing personnel to work smoothly on the platform. Below the drainage device 47 is a water outlet 46, the outer wall of which is fixedly connected to the inner wall of the outer shell 41. The interior of the drainage device 47 is connected to the interior of the water outlet 46. The top of the outer shell 41 is equipped with a moving plate 43, and the middle of the moving plate 43 is equipped with a movable plate 44. The outer wall of the movable plate 44 is movably connected to the inner wall of the outer shell 41, and the bottom surface of the movable plate 44 is fixedly connected with a reset spring 45.

[0025] Example 2

[0026] like Figure 3 As shown, based on Embodiment 1, the present invention provides a technical solution: the drainage device 47 includes a connecting block 471, the inside of the connecting block 471 is provided with a drainage pipe 473, one end of the drainage pipe 473 is connected to the outlet 46, the top of the connecting block 471 is fixedly connected with a suction pipe 472, and the two sides of the suction pipe 472 are provided with guide plates 474. The outer wall of the guide plate 474 is fixedly connected to the connecting block 471. By using the combination of the connecting block 471, the suction pipe 472 and the guide plate 474, when the water level in the water storage tank 42 exceeds the two sides of the guide plate 474, it will flow into the bottom of the suction pipe 472. When the water level exceeds the top of the suction pipe 472, the water below the suction pipe 472 is sucked into the drainage pipe 473 by the siphon principle and then discharged from the outlet 46, saving manpower to clean the water in the water storage tank 42.

[0027] Example 3

[0028] like Figure 4-5As shown, based on Embodiments 1 and 2, the present invention provides a technical solution: Preferably, the movable plate 44 includes a fixed plate 441, and a convex ball 442 is fixedly connected to the top of the fixed plate 441 to increase the friction of the surface of the fixed plate 441, making it less likely for people to slip when walking. The top of the fixed plate 441 is provided with a drainage groove 443, through which residual water on the surface of the fixed plate 441 can flow to the moving plate 43, reducing the retention of water. The convex ball 442 includes a spherical shell 421, and a connecting plate 422 is fixedly connected to the inner wall of the spherical shell 421. A compression spring 423 is fixedly connected to the bottom surface of the connecting plate 422, and a fixing block 424 is fixedly connected to the bottom surface of the compression spring 423. The bottom surface of the fixing block 424 is fixedly connected to the inner wall of the spherical shell 421.

[0029] The working principle of this stable bridge inspection platform will be explained in detail below.

[0030] like Figure 1-5 As shown, the bridge inspection vehicle lowers the chassis mechanism 4 to a designated position through the cooperation of the movable mechanism 1 and the connecting mechanism 3. Then, the direction of the chassis mechanism 4 is adjusted by the rotating mechanism 2. The inspection personnel stand inside the walking plate 43 to perform inspection work on the designated parts under the bridge. When seawater enters the walking plate 43 with the waves, the inspection personnel step on the movable plate 44, moving the movable plate 44 downward to compress the reset spring 45. After the movable plate 44 is pressed down, a gap is created between it and the walking plate 43. The water in 34 flows into the water storage tank 42 from the gaps on both sides of the movable plate 44. The water storage tank 42 stores the seawater. The water accumulated on the top of the movable plate 44 flows into 34 from the drainage trough 443, so that the water in the chassis mechanism 4 flows from... The system automatically discharges water to maintain a water-free environment and prevents water accumulation from affecting the work of testing personnel. When the chassis mechanism 4 shakes due to strong winds, the U-shaped water tank 42 causes the water inside to fluctuate with the shaking. The fluctuation of the water in the water tank 42 counteracts the frequency of the chassis mechanism 4 shaking due to the wind, forming a wind damper principle, thereby reducing vibration. When the water stored in the water tank 42 reaches a certain amount, the water enters the water guide plate 474. When the water level exceeds the top of the suction pipe 472, the water in the water guide plate 474 is automatically drawn from the suction pipe 472 to the drain pipe 473 through the siphon principle, and then discharged through the outlet 46, saving manpower to clean the water in the water tank 42.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
