Description

Technical Field

[0001] This invention belongs to the technical field of bridge construction equipment, specifically an inspection vehicle for inspecting the bottom of beams. Background Technology

[0002] Inspection vehicles used for beam bottom inspection are commonly known as bridge inspection vehicles (or bridge inspection trucks). They are special engineering vehicles designed specifically for close-range inspection of the bridge bottom, supports, webs, and other structures.

[0003] The existing bridge inspection equipment mainly consists of vehicle-mounted bridge inspection vehicles and permanent suspension bridge inspection vehicles. Permanent suspension bridge inspection vehicles require the installation of a large number of tracks on the bottom of the beam. When the wheels of permanent suspension bridge inspection vehicles start and brake, they will damage the track coating, resulting in damage and corrosion of both the tracks and the wheels. At the same time, due to the low frequency of use and lack of daily maintenance, the components will be further corroded and damaged. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: an inspection vehicle for inspecting the bottom of a bridge, comprising a bridge body, supports installed on both sides of the bridge body, and a track installed below the supports, and further comprising: The traveling mechanism is mounted on the track, the traveling frame is installed below the traveling mechanism, and the detection mechanism is slidably connected above the traveling frame; The walking mechanism includes a first carriage, an air-blowing assembly symmetrically arranged on the outside of the first carriage, and a cleaning assembly arranged at one end of the air-blowing assembly.

[0005] Furthermore, the walking mechanism also includes: A frame, which is installed below the first carriage; A baffle is installed on one side of the first carriage. The baffle engages the gap between the first carriage and the track, reducing the entry of dust and other impurities into the first carriage. The upper climbing frame is positioned above the first carriage.

[0006] Furthermore, the walking mechanism also includes: The lower climbing frame is installed below the first sliding frame and is connected to the traveling frame, allowing the detection mechanism to move back and forth on the traveling frame and scan and photograph the bottom of the bridge in coordination with the movement of the upper and lower climbing frames. The first roller is rotatably disposed inside the first carriage. The outer side of the first roller contacts the inner wall of the track. The first roller is engaged inside the I-shaped track, driving the first carriage to move.

[0007] Furthermore, the detection mechanism includes: The second carriage is slidably connected to the upper part of the traveling frame. The upper part of the traveling frame is provided with a groove so that the second roller can move along the traveling frame within the groove. The second roller is rotatably connected inside the second carriage, and the outside of the second roller is in contact with the outer wall of the traveling frame; The housing is installed above the second carriage. Together with the cover plate, the housing places the protective camera inside the housing during the retraction of the connecting rod, reducing the camera's contact with the outside world when not in use.

[0008] Furthermore, the detection mechanism also includes: A connecting rod is installed above the second carriage, and a support plate is provided above the connecting rod. The connecting rod drives the support plate to extend upward, making it easier for the camera to get closer to the bottom surface of the bridge. A protective assembly, which is mounted above a support plate; The camera is rotatably connected inside the protective assembly; A cover plate is symmetrically arranged inside the box, and the lower part of the cover plate is rotatably connected to the inside of the cover plate.

[0009] Furthermore, the air-blowing assembly includes: Gas cylinders, which are symmetrically arranged outside the first carriage; Piston plate, which is installed inside the gas tank, compresses the air out of the gas tank and sends it into the mounting housing through the gas pipe; A gas delivery pipe is installed at one end of the gas tank.

[0010] Furthermore, the cleaning assembly includes: The mounting shell is located at the other end of the gas supply pipe. An inflation hole is provided inside the mounting shell. Gas enters the mounting shell and is discharged through the inflation hole. It is blown from the internal outlet of the mounting shell to the rotating plate. A protrusion is provided inside the mounting shell near the inflation hole so that the airflow blows out from below the rotating plate, causing the rotating plate to rotate. A rotating plate is rotatably connected inside the mounting housing, and the size of the rotating plate is the same as the size of the outlet of the mounting housing; A rotating rod is installed inside the rotating housing on the side away from the rotating plate. Under normal circumstances, the rotating rod is in a position close to the inside of the housing, allowing the rotating plate to rotate freely and sweeping debris out of the track. A scraper is disposed at one end of the mounting housing.

[0011] Furthermore, the cleaning assembly also includes: The push plate is located inside the mounting shell at one end away from the rotating rod. By pushing the push plate outward, the water-absorbing block is deformed by the pressure of the push plate and the inner wall of the mounting shell, thus discharging the absorbed water. A water-absorbing block, which is disposed inside the mounting shell, and is made of a deformable material; The fixing teeth are installed on the outside of the mounting shell, which allow the water squeezed out of the water-absorbing block to be discharged quickly while maintaining the deformation of the water-absorbing block.

[0012] Furthermore, the protective component includes: A base, which is mounted above a support plate; A connecting frame is rotatably connected to the top of the base. The connecting frame allows the camera to rotate left and right, making it easy to capture images of various corners under the bridge. The elastic plate is fitted around the outside of the connecting frame at its lower part, and the upper part of the elastic plate is made of an elastic material that can deform.

[0013] Furthermore, the protective component also includes: An anti-slip strip is provided above the elastic plate. The anti-slip strip is used to increase the friction with the camera, so that the camera can be stuck on the elastic plate. A support plate, wherein the support plate is disposed on the side of the elastic plate away from the anti-slip strip; A pad is placed above the support plate. The surface of the pad is covered with a cleaning cloth to clean dust from the camera lens and to keep the camera isolated from the outside world when not in use.

[0014] The beneficial effects of this invention are as follows: 1. This invention, by setting up a walking mechanism, allows the sweeping component to clean the contact surface of the track during movement, reducing the amount of external debris adhering to the track and preventing hard-to-clean debris from being rolled into the first roller, causing jamming. The air blowing component works with the sweeping component to blow away debris covering the track surface, and also allows rainwater on the track to quickly leave the track after rain, reducing rust and facilitating the sweeping component to maintain and clean the track, reducing jamming and wear of the first roller.

[0015] 2. This invention, by setting up a detection mechanism and controlling the height of the camera via a linkage, can more accurately capture details such as cracks at the bottom of bridges, facilitating staff judgment and maintenance. When the camera is retracted, the protective component, through the rotation of the camera, abuts and wraps around the lens of the camera, blocking the lens area and isolating it from the outside world. Driven by the linkage, it enters the housing, where the cover plate covers the housing, reducing the camera's contact with the outside environment. After inspection, it is stored separately to prevent the camera from being exposed to the environment for a long time due to lack of use, which could lead to dust accumulation or rust affecting the sensitivity.

[0016] 3. By setting up a protective component, the lens end of the camera is rotated downwards to the bottom. At this time, the protrusion on the left side of the elastic plate contacts the bottom of the camera and presses downwards, causing the elastic plate to deform. Finally, the pad contacts the lens of the camera, allowing the pad to block the lens. This cleans the lens while preventing external dust from adhering to the lens surface, and isolates lenses that are not used for a long time for storage, thus strengthening the protection of the camera.

[0017] 4. This invention, through the inclusion of a cleaning component, uses a scraper to clean the inner side of the track during the movement of the first carriage, reducing contact between debris and rainwater on the track and the first roller. An air inlet blows air under the rotating plate, causing debris that cannot be easily blown away to be repeatedly tapped by the rotating plate until it loosens and falls off, and is then blown outwards. In rainy or snowy weather, most of the moisture and snow adhering to the track is cleaned by the scraper. During continued movement, a water-absorbing block absorbs and cleans the moisture on the track, and a pusher plate squeezes the water-absorbing block to expel excess water, keeping the track dry, reducing friction with the first roller, maintaining track durability, and reducing paint peeling.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: an inspection vehicle for inspecting the bottom of a beam, as described below.

[0022] The bridge includes a bridge body 1, supports 2 installed on both sides of the bridge body 1, and a track 3 installed below the supports 2, and also includes: The walking mechanism 4 is set on the track 3, the walking frame 5 is installed below the walking mechanism 4, and the detection mechanism 6 is slidably connected above the walking frame 5; The bracket 2 is installed on both sides of the bridge body 1, so that the track 3 can be fixed to the side of the bridge. The traveling mechanism 4 travels along the track 3, so that the traveling frame 5 can move horizontally along the bottom of the bridge. The detection mechanism 6 moves laterally on the traveling frame 5. As the traveling mechanism 4 moves along the bridge, the detection mechanism 6 monitors and photographs various parts of the bottom of the bridge, and conducts a comprehensive inspection of the bottom of the beam.

[0023] The walking mechanism 4 includes a first carriage 401, an air blowing assembly 403 symmetrically arranged on the outside of the first carriage 401, and a cleaning assembly 404 arranged at one end of the air blowing assembly 403.

[0024] The walking mechanism 4 also includes: The frame 405 is installed below the first carriage 401; Baffle 408 is installed on one side of the first carriage 401. Baffle 408 makes the gap between the first carriage 401 and the track 3 engage, reducing the entry of dust and other impurities into the first carriage 401. The upper climbing frame 406 is located above the first slide 401.

[0025] The walking mechanism 4 also includes: The lower climbing frame 407 is installed below the first sliding frame 401. The lower climbing frame 407 is connected to the traveling frame 5, so that the detection mechanism 6 can move back and forth on the traveling frame 5 and scan and photograph the bottom of the bridge in coordination with the movement of the upper and lower climbing frames 407. The first roller 402 is rotatably disposed inside the first carriage 401. The outer side of the first roller 402 contacts the inner wall of the track 3. The first roller 402 is locked inside the I-shaped track 3, driving the first carriage 401 to move.

[0026] During testing, the first roller 402 inside the first carriage 401 moves along the track 3, causing the frame 405 to move along the track 3, which in turn moves the traveling frame 5. The upper climbing frame 406 and the lower climbing frame 407 allow workers to pass through and stand on the traveling frame 5. The cleaning component 404 cleans the contact surface of the track 3 during movement, reducing the amount of external debris adhering to the track 3 and preventing hard-to-clean debris from being rolled into the first roller 402, causing jamming. The air blowing component 403 works with the cleaning component 404 to blow away the debris covering the surface of the track 3, and also allows rainwater on the track 3 to quickly leave the track 3 after rain, reducing rust and facilitating the cleaning component 404 to maintain and clean the track 3, reducing jamming and wear of the first roller 402.

[0027] Detection mechanism 6 includes: The second slide 601 is slidably connected to the upper part of the traveling frame 5. The upper part of the traveling frame 5 is provided with a groove so that the second roller 602 can move along the traveling frame 5 within the groove. The second roller 602 is rotatably connected to the inside of the second carriage 601, and the outside of the second roller 602 is in contact with the outer wall of the traveling frame 5. The housing 603 is installed above the second carriage 601. Together with the cover plate 604, the housing 603 places the protective component 607 and camera 608 inside the housing 603 during the retraction of the connecting rod 605, thereby reducing the contact between the camera 608 and the outside world when not in use.

[0028] Detection mechanism 6 also includes: Link 605 is installed above the second carriage 601. A support plate 606 is provided above the link 605. The link 605 drives the support plate 606 to extend upward, so that the camera 608 can get closer to the bottom surface of the bridge. Protective component 607 is mounted on top of support plate 606; Camera 608 is rotatably connected inside the protective component 607; Cover plate 604 is symmetrically arranged inside the housing 603, and the lower part of cover plate 604 is rotatably connected to the interior of cover plate 604.

[0029] As the traveling mechanism 4 moves along the bridge, the second roller 602 drives the second carriage 601 to move along the traveling frame 5, and the height of the camera 608 is controlled by the connecting rod 605, which can more accurately capture details such as cracks at the bottom of the bridge, making it easier for staff to judge and maintain. When the camera 608 is retracted, the protective component 607 abuts and wraps against the lens part of the camera 608 through the rotation of the camera 608, blocking the lens part of the camera 608 and keeping it isolated from the outside world. Driven by the connecting rod 605, it enters the housing 603, so that the cover plate 604 covers the housing 603, reducing the contact between the camera 608 and the outside world. After the inspection is completed, it is stored separately to avoid the camera 608 being exposed to the outside environment and easily affected by environmental factors, such as dust accumulation or rust on parts, which may affect its sensitivity.

[0030] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the air blowing assembly 403 includes: Gas tank 4031 is symmetrically arranged outside the first slide 401. One end of the gas tank 4031 is provided with a one-way air inlet, which causes the plug plate to move back and forth to send gas into the mounting shell 4041. Piston plate 4032 is installed inside gas tank 4031. Piston plate 4032 squeezes the air out of gas tank 4031 and enters the mounting shell 4041 through gas pipe 4033. Gas pipe 4033 is located at one end of gas tank 4031.

[0031] Cleaning component 404 includes: Mounting housing 4041 is located at the other end of air supply pipe 4033. An air inlet 4042 is provided inside the mounting housing 4041. Gas enters the mounting housing 4041 and is discharged through the air inlet 4042. The gas is blown from the internal outlet of the mounting housing 4041 toward the rotating plate 4043. A protrusion is provided inside the mounting housing 4041 near the air inlet 4042 so that the airflow blows out from below the rotating plate 4043, causing the rotating plate 4043 to rotate. Rotating plate 4043 is rotatably connected inside mounting housing 4041, and the size of rotating plate 4043 is the same as the outlet size of mounting housing 4041; Rotating rod 4044 is installed inside the rotating housing on the side away from the rotating plate 4043. Under normal circumstances, the rotating rod 4044 is in a position close to the inside of the mounting housing 4041, so that the rotating plate 4043 can rotate freely and sweep the debris on the track 3 outward. Scraper 4045 is disposed at one end of mounting housing 4041.

[0032] Cleaning component 404 also includes: Push plate 4046 is located inside the mounting shell 4041 at one end away from the rotating rod 4044. Push plate 4046 pushes outward, causing the water-absorbing block 4047 to be squeezed and deformed by the push plate 4046 and the inner wall of the mounting shell 4041, thus discharging the absorbed water. Water-absorbing block 4047 is located inside the mounting shell 4041 and is made of a deformable material. The fixing teeth 4048 are installed on the outside of the mounting shell 4041. While maintaining the deformation of the water-absorbing block 4047, the water squeezed out by the water-absorbing block 4047 can be discharged quickly.

[0033] During use, the stopper plate moves back and forth, sending gas into the mounting housing 4041. The gas enters the mounting housing 4041 through the air inlet 4042 and blows the rotating plate 4043, then is discharged outward. The discharged gas blows the inside of the side of the track 3. The scraper 4045 cleans the inside of the track 3 during the movement of the first carriage 401, reducing the contact between debris on the track 3 and rainwater and the first roller 402. The air inlet 4042 blows air under the rotating plate 4043, so that debris that cannot be easily blown away is repeatedly knocked by the rotating plate 4043 until it loosens and falls off, and the debris is blown outward. In rainy or snowy weather, most of the water and snow adhering to the track 3 are cleaned by the scraper 4045. During the continued movement, the water-absorbing block 4047 absorbs and cleans the water on the track 3, and the pusher plate 4046 squeezes the water-absorbing block 4047 to discharge the excess water, keeping the track 3 dry, reducing friction with the first roller 402, maintaining the use of the track 3, and reducing paint peeling.

[0034] Protective component 607 includes: Base 6071, base 6071 is installed above support plate 606; The connecting frame 6072 is rotatably connected to the top of the base 6071. The connecting frame 6072 allows the camera 608 to rotate left and right, making it convenient to shoot various corners under the bridge. Elastic plate 6073 is fitted around the outside of connecting frame 6072 at the bottom, and the top of elastic plate 6073 is made of elastic material that can deform.

[0035] Protective component 607 also includes: Anti-slip strip 6074 is set above elastic plate 6073. Anti-slip strip 6074 is used to increase friction with camera 608 so that camera 608 can be stuck on elastic plate 6073. Support plate 6075 is located on the side of elastic plate 6073 away from anti-slip strip 6074; The pad 6076 is positioned above the support plate 6075. The pad 6076 is circular and has a cleaning cloth on its surface to clean the dust on the lens of the camera 608 and to keep the camera 608 isolated from the outside world when not in use.

[0036] The camera 608 swings left and right on the connecting frame 6072 to capture images of multiple sides of the bridge. After the camera 608 is finished using the equipment, the lens of the camera 608 rotates downward to the bottom. At this time, the left protrusion of the elastic plate 6073 contacts the bottom of the camera 608 and presses downward, causing the elastic plate 6073 to deform. Finally, the pad 6076 contacts the lens of the camera 608, allowing the pad 6076 to block the lens. This cleans the lens and prevents external dust from adhering to the lens surface, thus isolating and storing lenses that are not used for a long time and strengthening the protection of the camera 608.

[0037] The specific workflow is as follows: The bracket 2 is installed on both sides of the bridge body 1 so that the track 3 can be fixed to the side of the bridge. The walking mechanism 4 walks along the track 3. During the inspection, the first roller 402 in the first slide 401 walks along the track 3, so that the frame 405 moves along the track 3, driving the walking frame 5 to move. The upper climbing frame 406 and the lower climbing frame 407 can allow workers to pass through and stand on the walking frame 5. The cleaning component 404 cleans the contact surface of the track 3 during the movement, reducing the external debris attached to the track 3 and preventing hard-to-clean debris from being rolled into the first roller 402, causing jamming. The air blowing component 403 works with the cleaning component 404 to blow away the debris covering the surface of the track 3, and also allows the rainwater on the track 3 to get off the track 3 as soon as possible after rain. As the traveling mechanism 4 moves along the bridge, the second roller 602 drives the second carriage 601 to move along the traveling frame 5, and the height of the camera 608 is controlled by the connecting rod 605, which can more accurately capture details such as cracks at the bottom of the bridge, making it easier for staff to judge and maintain. When the camera 608 is retracted, the protective component 607 abuts and wraps against the lens part of the camera 608 through the rotation of the camera 608, blocking the lens part of the camera 608 and keeping it isolated from the outside world. Driven by the connecting rod 605, it enters the box 603, so that the cover plate 604 covers the box 603, reducing the contact between the camera 608 and the outside world. After the inspection is completed, it is stored separately to avoid the camera 608 being exposed to the outside world and susceptible to environmental influences due to long-term disuse.

[0038] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
