Description
Technical Field
[0001] The present application relates to the field of bridge detection, and in particular to a bridge detection device. Background Art
[0002] During the use of the bridge, it is necessary to inspect the bridge regularly. The inspection of the bridge deck can be completed manually on the bridge deck, while the inspection of the bridge bottom is more inconvenient. Currently, the inspection is mainly carried out through the following two methods.
[0003] The first method involves constructing a base frame at the bottom of the bridge for inspection, with workers climbing onto it. The base frame is typically located on the ground or on a boat. The second method involves utilizing a large bridge inspection vehicle that can travel over the bridge deck. This vehicle is equipped with a work platform that can be moved to the bottom of the bridge, where workers inspect the bridge floor. In actual use, both of these inspection methods are found to be relatively cumbersome, resulting in low inspection efficiency. Summary of the Invention
[0004] In order to improve the convenience of bridge inspection and improve the inspection efficiency, the present application provides a bridge inspection device.
[0005] The bridge inspection equipment provided in this application adopts the following technical solution:
[0006] A bridge inspection device comprises: a traveling underframe, the traveling underframe comprising two bottom beams arranged in parallel, a connecting assembly connecting the two bottom beams, and traveling wheels arranged at the bottom of the bottom beams, the connecting assembly being used to connect the two bottom beams;
[0007] The detection frame includes a support beam horizontally arranged on each bottom beam, a support rod arranged between the support beam and the bottom beam, a sliding seat slidably arranged on the support beam, and a telescopic shaft rotatably arranged between the two sliding seats, wherein the ends of the support beam extend out of the bottom beam;
[0008] The detection module includes a detection probe rotatably connected to the end of the telescopic shaft and a display arranged on the detection frame. The display has a built-in controller, and the detection probe is electrically connected to the controller.
[0009] By adopting the above technical solution, when inspecting the bridge on the ground under the bridge, the telescopic shaft is flipped to a vertical state with the detection probe facing upward, and then the telescopic shaft is used to drive the detection probe to the detection position, and the real-time image of the detection probe is displayed on the display. At the same time, the equipment is controlled through the display to complete the inspection.
[0010] When working conditions are not available under the bridge, the equipment is pushed to the edge of the bridge, with the support beam extended beyond the bridge deck. The sliding seat is then slid to the end of the support beam. The telescopic shaft is then flipped so that the detection probe faces downward. The rotatable detection probe takes real-time images of the bridge bottom. Workers on the bridge deck can view the real-time images from the detection probe on a display, making bridge inspection easier. The entire operation is simple and convenient, eliminating the need for a chassis, vessels, or large surveying vehicles. This greatly improves the convenience and efficiency of inspections while reducing safety hazards.
[0011] Optionally, the connecting assembly includes two cross-arranged connecting rods and a fixed rod, the ends of the two connecting rods are connected to the bottom beam, the fixed rod is a square rod, and the fixed rod passes through the overlapping part of the two connecting rods.
[0012] By adopting the above technical solution, two cross-arranged connecting rods are used to connect the two bottom beams, thereby forming two triangles between the two bottom beams and the connecting rods. The stability of the triangle is utilized to improve the stability of the walking frame. At the same time, the fixed rod limits the two connecting rods, reducing the possibility of relative rotation between the two connecting rods.
[0013] Optionally, the sliding seat includes a sliding ring mounted on the outside of the support beam, a fixed disk arranged on the sliding ring, and a rotating disk rotatably arranged on the fixed disk. The sliding ring is provided with a positioning pin, and a plurality of pin holes are provided on the support beam. The positioning pins are plugged into the pin holes. The telescopic shaft is connected between the two rotating disks, and the fixed disk is provided with a flip motor for driving the rotating disk to rotate.
[0014] By adopting the above technical solution, a sliding ring is slidably mounted on the outside of the support beam, making it easy to adjust the position of the sliding seat. After adjusting the position of the sliding ring, the sliding seat is fixed with a positioning pin. Then, a turning motor is used to drive the rotating disk to rotate, thereby realizing the turning of the telescopic shaft, improving the convenience of detection.
[0015] Optionally, a plug-in shaft is coaxially provided on one of the rotating disks, and a connecting groove is provided on the other rotating disk. The plug-in shaft is a polygonal shaft, and a telescopic shaft is passed through the end of the plug-in shaft and is plugged into the connecting groove.
[0016] By adopting the above technical solution, the plug-in shaft is plugged into the connecting groove to connect the two rotating disks into a whole. When one rotating disk rotates, the other rotating disk will rotate synchronously, thereby reducing the possibility of the two rotating disks rotating out of sync.
[0017] Optionally, an arc-shaped limiting groove is provided on each side of the two rotating disks that are close to each other, and the telescopic shaft is located inside the limiting groove.
[0018] By adopting the above technical solution, when the two rotating disks rotate synchronously, the telescopic shaft is limited by the limiting groove, so that the telescopic shaft can be flipped and the stability of the flipping of the telescopic shaft is improved.
[0019] Optionally, the telescopic shaft includes a fixed shaft rotatably connected to the sliding seat and a pneumatic telescopic rod coaxially arranged on the fixed shaft.
[0020] By adopting the above technical solution, the telescopic shaft is extended and retracted using a pneumatic telescopic rod, thereby facilitating the detection probe to be sent close to a position that needs to be detected.
[0021] Optionally, a plurality of sleeves are provided on the bottom beam, the sleeves are vertically arranged and sealed at the top, and each sleeve is threadedly connected to a support block. When the bottom beam is in operation, the support block contacts the ground.
[0022] By adopting the above technical solution, the height of the support block is adjusted by rotating the support block threadedly connected to the inside of the sleeve. When the equipment is operating, the support block contacts the ground, thereby providing stable support for the bottom beam.
[0023] Optionally, a driving motor for driving the support block to rotate is provided on the top of each sleeve, a spirit level is provided on the walking chassis, and the spirit level and the driving motor are both electrically connected to a controller.
[0024] By adopting the above technical solution, a spirit level is used to detect the posture of the walking frame, and the signal is transmitted to the controller. The controller controls the drive motor to drive the support blocks to rotate, so that after several support blocks rotate, the walking frame is adjusted to a horizontal state, which is convenient for working on slopes.
[0025] Optionally, a pressure plate is provided on the support rod, and the pressure plate includes a ring mounted on the outside of the support rod, a pressure rod hinged on the ring, and a positioning plate hinged on the end of the pressure rod. The positioning plate is parallel to the ground for staff to step on or heavy objects to press on.
[0026] By adopting the above technical solution, the ring mounted on the support rod can conveniently adjust the position of the positioning plate through its own rotation. When the equipment is working, the positioning plate is placed on the ground. The staff steps on the positioning plate or presses the positioning plate with a heavy object, thereby applying a downward force to the walking chassis, making the detection equipment work more stably.
[0027] Optionally, the positioning plate includes a main body plate and folding plates hinged on both sides of the main body plate.
[0028] By adopting the above technical solution, the positioning plate is set in a foldable form, so that when the positioning plate is folded, it is convenient to fold the positioning plate and tie it to the support rod with a rope or a cable tie, so as to facilitate the storage of the pressure plate.
[0029] In summary, this application includes at least one of the following beneficial technical effects:
[0030] 1. When inspecting the bridge on the ground under the bridge, flip the telescopic shaft to a vertical position with the detection probe facing upwards, and then use the telescopic shaft to drive the detection probe to the detection position, display the real-time image of the detection probe on the monitor, and control the equipment through the monitor to complete the inspection. When there is no working ground under the bridge, push the equipment to the edge of the bridge, and extend the support beam out of the bridge deck, then slide the sliding seat to the end of the support beam, and then flip the telescopic shaft so that the detection probe faces downwards. The rotatable detection probe is aimed at the bottom of the bridge for real-time shooting. At this time, the staff on the bridge deck can view the real-time image of the detection probe through the monitor, which facilitates the inspection of the bridge. The entire operation process is simple and convenient, without the need for ships and large surveying vehicles, which greatly improves the convenience and efficiency of inspection, while reducing the safety hazards of inspection operations.
[0031] 2. Use two cross-arranged connecting rods to connect the two bottom beams, so that two triangles are formed between the bottom beams and the connecting rods. The stability of the triangle is used to improve the stability of the walking frame. At the same time, the fixed rod limits the two connecting rods to reduce the possibility of rotation of the two connecting rods.
[0032] 3. The collar mounted on the support rod facilitates the adjustment of the position of the positioning plate by its own rotation. When the equipment is working, the positioning plate is placed on the ground. The staff steps on the positioning plate or presses the positioning plate with a heavy object, thereby applying a downward force to the walking chassis, making the detection equipment work more stably.

[0039] The following is combined with Figure 1-4 This application is described in further detail.
[0040] An embodiment of the present application discloses a bridge detection device.
[0041] Reference Figure 1 A bridge inspection device includes a traveling chassis 1, an inspection frame 2, and an inspection module 3. The inspection frame 2 is mounted on the traveling chassis 1, enabling the inspection device to travel. The inspection frame 2 provides a mounting base for some components of the inspection module 3. After the traveling chassis 1 reaches the inspection position, the inspection module 3 performs an inspection of the bridge.
[0042] Reference Figure 1 and Figure 2 The walking chassis 1 includes a bottom beam 11, a connecting assembly 12, and walking wheels 13. Two bottom beams 11 are provided in parallel and horizontally. Two walking wheels 13 are provided at the bottom of each bottom beam 11. The connecting assembly 12 is located between the two bottom beams 11 and includes a connecting rod 121 and a fixed rod 122. Two connecting rods 121 are provided crosswise. Both ends of the connecting rod 121 are fixedly connected to the bottom beam 11. The fixed rod 122 is a square rod. The fixed rod 122 is fixedly provided at the position where the two connecting rods 121 overlap to limit the two fixed rods 122.
[0043] Reference Figure 1 The inspection frame 2 includes a support beam 21, a support rod 22, a sliding seat 23, and a telescopic shaft 24. A support beam 21 is provided parallel to each bottom beam 11. The support beam 21 is longer than the bottom beam 11, so that the end of the support beam 21 extends beyond the bottom beam 11. Two support rods 22 are fixedly provided between each support beam 21 and the bottom beam 11, and the two support rods 22 are arranged in an inverted eight shape.
[0044] Reference Figure 1 and Figure 2 A sliding seat 23 is slidably provided on each support beam 21. The sliding seat 23 includes a sliding ring 231, a fixed disk 232 and a rotating disk 233. The sliding ring 231 is slidably sleeved on the outside of the support beam 21, and a positioning pin 234 is passed through the sliding ring 231. A plurality of pin holes 211 are opened on the support beam 21 along its own length direction. The positioning pin 234 passes through the sliding ring 231 and is plugged into the pin hole 211 to position the sliding ring 231 after sliding.
[0045] Reference Figure 1 and Figure 2 The fixed disk 232 is fixedly connected to the sliding ring 231, and each rotating disk 233 is rotatably connected to one of the fixed disks 232. A flip motor 236 is fixedly installed on one of the fixed disks 232, and the flip motor 236 drives the rotating disks 233 to rotate through a gear transmission. A plug-in shaft 235 is coaxially fixed to one of the rotating disks 233. The plug-in shaft 235 is a polygonal shaft. The other rotating disk 233 has a connecting groove 2331. The plug-in shaft 235 is plugged into the connecting groove 2331. When the flip motor 236 is working, the two rotating disks 233 rotate synchronously.
[0046] Reference Figure 1 and Figure 2 The telescopic shaft 24 includes a fixed shaft 241 and a pneumatic telescopic rod 242. The pneumatic telescopic rod 242 is coaxially fixed to the fixed shaft 241. An arc-shaped limiting groove 2332 is provided on the side of the two rotating disks 233 that are close to each other. The fixed shaft 241 is located within the limiting groove 2332. The plug-in shaft 235 passes through the fixed shaft 241 and is limited by the limiting groove 2332. When the two rotating disks 233 rotate synchronously, the telescopic shaft 24 is driven to flip.
[0047] Reference Figure 1 and Figure 2 The detection module 3 includes a detection probe 31 and a display 32. The detection probe 31 is rotatably connected to the end of the pneumatic telescopic rod 242. The display 32 is fixedly set on the detection frame 2. The display 32 has a built-in controller. The detection probe 31 and the flip motor 236 are electrically connected to the controller.
[0048] Reference Figure 1 、 Figure 2 and Figure 3When working on the ground under the bridge, the pneumatic telescopic rod 242 is used to directly drive the detection probe 31 to the position to be inspected, and the staff can view the real-time image of the detection probe 31 on the display 32. When there is no working space under the bridge, the equipment is pushed to the edge of the bridge, and the sliding seat 23 slides to the end of the support beam 21. The reversing motor 236 then drives the telescopic shaft 24 to flip so that the detection probe 31 faces downward. The rotatable detection probe 31 is aimed at the bottom of the bridge for real-time imaging. The staff on the bridge deck can view the real-time image of the detection probe 31 on the display 32, thus completing the bridge inspection. The entire process is simple and fast.
[0049] Reference Figure 1 and Figure 2 In order to improve the working stability of the detection equipment and reduce the possibility of the walking chassis 1 moving after the telescopic shaft 24 is turned over, a spirit level 111 is fixedly installed on the walking chassis 1, and a number of sleeves 14 are fixedly installed on the side walls of each bottom beam 11. In this embodiment, two sleeves are used as an example. The sleeves 14 are vertically arranged, and the top of the sleeves 14 are sealed. A support block 141 is threadedly connected inside each sleeve 14, and the support block 141 is made of rubber. A driving motor 142 is fixedly installed on the top of each sleeve 14. The motor shaft of the driving motor 142 rotates and passes through the top of the sleeve 14, and slides coaxially through the top of the support block 141. The motor shaft of the driving motor 142 and the top of the support block 141 are circumferentially limited by a key. The motor shaft of the driving motor 142 drives the support block 141 to rotate synchronously, but does not affect the up and down movement of the support block 141. The spirit level 111 and the driving motor 142 are both electrically connected to the controller.
[0050] Reference Figure 1 and Figure 2 When the detection equipment is operating, the posture of the walking frame 1 is detected by the level meter 111, and then the driving motor 142 is controlled by the controller to work. By adjusting the height of each support block 141, not only the support block 141 is in contact with the ground, but also the walking frame 1 is in a horizontal state, thereby improving the stability of the operation.
[0051] Reference Figure 2 and Figure 4 In order to prevent the walking chassis 1 from tipping over, a pressing plate 4 is provided on each support rod 22. Each pressing plate 4 includes a collar 41, a pressure rod 42 and a positioning plate 43. The collar 41 is sleeved on the outside of the support rod 22. One end of the pressure rod 42 is hinged to the collar 41. The positioning plate 43 includes a main body plate 431 and folding plates 432 hinged on both sides of the main body plate 431. The main body plate 431 is hinged to the other end of the pressure rod 42.
[0052] Reference Figure 2 and Figure 4When the pressure plate 4 is not in use, the foldable positioning plate 43 is folded and tied to the support rod 22 with a rope or a cable tie. When the pressure plate 4 is in use, the position of the positioning plate 43 is adjusted by rotating the ring 41. Before the equipment is operated, the positioning plate 43 is folded and placed on the ground. The positioning plate 43 is stepped on by a worker or pressed with a heavy object to apply a downward force to the bottom beam 11, making the detection equipment more stable.
[0053] The bridge inspection device of the present embodiment is implemented as follows: upon arrival at the work site, if the inspection can be performed on the ground beneath the bridge, the traveling chassis 1 is first pushed to the inspection position. Once at the work position, the height of each support block 141 is adjusted to keep the traveling chassis 1 horizontal. The inspection probe 31 is then raised to the inspection height directly via the pneumatic telescopic rod 242. A worker, viewing the real-time image of the inspection probe 31 on the display 32 below, inspects the bridge.
[0054] When there is no working ground under the bridge, place the equipment at the edge of the bridge deck and extend the support beam 21 out of the bridge deck. First, adjust the height of each support block 141, then lower the pressure plate 4 and apply weight to the pressure plate 4 to keep the walking frame 1 stable. Slide the sliding seat 23 to the end of the support beam 21 and position it. Then control the turning motor 236 to drive the telescopic shaft 24 to turn so that the detection probe 31 is facing downward (such as Figure 3 As shown), the rotatable detection probe 31 is then aimed at the bottom of the bridge for real-time shooting. The staff on the bridge deck views the real-time image of the detection probe 31 through the display 32 to detect the bridge.
[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
