Description

Technical Field

[0001] This invention relates to the field of bridge paving technology, specifically to a crack detection device for bridge paving. Background Technology

[0002] During bridge paving, a crack detection device is needed to inspect the bridge surface for any breaks or cracks. If cracks are found, they need to be repaired during the paving process. This requires the use of a crack detection device to inspect the cracked areas of the bridge, facilitating subsequent cleaning. However, this crack detection device has some drawbacks:

[0003] Firstly, most crack detection equipment is quite large, making it very troublesome and space-consuming to move or store.

[0004] Secondly, it lacks the function of protecting the internal electronic equipment. Because it is a construction site, the electronic equipment is easily damaged by bumps and knocks, which is very troublesome.

[0005] Third, it lacks the function of assisting in linear movement. Summary of the Invention

[0006] The purpose of this invention is to provide a crack detection device for bridge pavement, in order to solve the problems mentioned in the background art, such as large footprint and storage space occupation; lack of function to protect internal electronic equipment; and lack of function to assist straight-line driving.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a crack detection device for bridge pavement, comprising:

[0008] The fixed block is a major component of the detection device. A barrier plate is fixedly installed on the outer surface of the fixed block, and the barrier plate is symmetrically distributed about the longitudinal center line of the fixed block.

[0009] A protective plate is fixedly installed on the top surface of the fixed block, and a display screen is installed on one side of the protective plate;

[0010] A cylindrical block penetrates the outer surface of the fixed block, and a support block is fixedly provided at one end of the cylindrical block.

[0011] As a preferred embodiment of the present invention, the top surface of the fixing block is penetrated by the extrusion plate, the outer surface of the extrusion plate is penetrated by the protective plate, the extrusion plate forms a sliding structure with the fixing block and the protective plate respectively, a return spring is fixedly provided on the top and bottom surfaces of the extrusion plate, the return spring is fixedly provided on the top surface of the fixing block, and the fixing block forms an elastic structure with the extrusion plate through the return spring.

[0012] Using the above technical solution, when the extrusion plate is subjected to the elastic force of the return spring, the extrusion plate will move downward.

[0013] As a preferred embodiment of the present invention, the bottom end of the extrusion plate is connected to a connecting rod, the bottom end of the connecting rod is connected to a top rod, the top rod and the extrusion plate both form a rotating structure with the connecting rod, the top rod and the extrusion plate both form a sliding structure with the fixed block, the connecting rod penetrates the inner surface of the groove, the groove has two openings at 90° on the outer surface of the cylindrical block, the cylindrical block is engaged with the connecting rod through the groove, and the cylindrical block and the fixed block form a rotating structure.

[0014] Using the above technical solution, when the extrusion plate moves downward, the extrusion plate will drive the top end of the connecting rod to move downward, so that the connecting rod will drive the top end of the push rod to move, allowing the push rod to be inserted into the groove. By engaging with the groove, the cylindrical block is prevented from rotating.

[0015] As a preferred embodiment of the present invention, the outer surface of the support block is penetrated by an outer ring block, and a connecting block is fixedly provided on the inner surface of the outer ring block. The connecting block and the outer ring block are both installed inside the fixed block to form a rotating structure. The inner surface of the connecting block is penetrated by a screw, and a limit block is connected to the top surface of the screw. The connecting block and the screw are meshed together.

[0016] Using the above technical solution, when the outer ring block is rotated, the outer ring block will drive the connecting block to rotate, so that the connecting block meshes with the screw, allowing the screw to slide.

[0017] As a preferred embodiment of the present invention, the screw and the support block form a sliding structure through the limiting block, the screw penetrates the bottom surface of the support block, the bottom surface of the screw is fixedly connected to a fixing plate, the bottom surface of the fixing plate is fixedly provided with a second roller, and one side surface of the support block is fixedly provided with a first roller.

[0018] Using the above technical solution, when the screw slides, it will drive the limit block to move, and the limit block will prevent the screw from sliding out. The sliding of the screw will also drive the fixed plate to slide, so that the second roller on the fixed plate will also move. The whole can be moved by the second roller or the first roller.

[0019] As a preferred embodiment of the present invention, a push plate is fixedly provided on one side surface of the support block. The push plate is located below the extrusion block, which is located inside the fixed block. One end of the extrusion block is connected to a guide rod, and the end of the guide rod is connected to a detection camera. The detection camera penetrates the bottom surface of the fixed block, and the output end of the detection camera is connected to the input end of the display screen.

[0020] Using the above technical solution, when the support block is driven to rotate, the push plate on the support block also rotates accordingly, thereby squeezing the extrusion block.

[0021] As a preferred embodiment of the present invention, the detection camera and the extrusion block both form a rotating structure with the guide rod, and the detection camera and the extrusion block both form a sliding structure with the fixed block. A support spring is fixedly connected to the outer surface of the detection camera, and the support spring is fixedly disposed inside the fixed block. The fixed block and the detection camera form an elastic structure through the support spring.

[0022] Using the above technical solution, when the extrusion block is extruded, the extrusion block will drive the top of the guide rod to move, so that the end of the guide rod can drive the detection camera to move. Thus, when the detection camera moves downward, it can compress and charge the support spring and slide out of the fixed block, which facilitates detection.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the crack detection device for bridge pavement:

[0024] 1. This device can pull the squeezing plate, causing it to detach from the groove via the connecting rod and the top rod. This allows the cylindrical block to rotate, driving the support block to rotate and change direction, making the detection camera more closely aligned with the ground for clear imaging and detection. The squeezing plate can then be released again, and the groove can be re-engaged by the reset spring, achieving the function of changing the occupied area, which is very convenient.

[0025] 2. At the same time, when the support block rotates, the push plate on the support block will squeeze the extrusion block, so that the extrusion block will push the detection camera through the guide rod, pushing it out for easy detection. When not in use, it will be stored inside for easy storage and to prevent damage.

[0026] 3. At the same time, by rotating the outer ring block, the connecting block and the screw can be rotated, which facilitates engagement with the screw. The screw moves downward through the limiting block to push the fixing plate, which causes the fixing plate to extend so that the second roller can fit against the inner wall of the bridge. This allows the entire structure to move linearly by fitting the second roller against the inner wall. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-7 The present invention provides a technical solution: a crack detection device for bridge pavement, comprising:

[0037] Fixed block 1 is the main component of the detection device. A baffle plate 2 is fixedly installed on the outer surface of fixed block 1. The baffle plate 2 is symmetrically distributed about the longitudinal center line of fixed block 1.

[0038] The protective plate 3 is fixedly installed on the top surface of the fixed block 1, and a display screen 4 is installed on one side of the protective plate 3;

[0039] A cylindrical block 10 penetrates the outer surface of the fixed block 1, and a support block 11 is fixedly installed at one end of the cylindrical block 10.

[0040] The top surface of the fixed block 1 is penetrated by the extrusion plate 5, and the outer surface of the extrusion plate 5 is penetrated by the protective plate 3. The extrusion plate 5 forms a sliding structure with the fixed block 1 and the protective plate 3 respectively. A return spring 6 is fixedly installed on the top and bottom surfaces of the extrusion plate 5. The return spring 6 is fixedly installed on the top surface of the fixed block 1. The fixed block 1 and the extrusion plate 5 form an elastic structure through the return spring 6. When the extrusion plate 5 is subjected to the elastic force of the return spring 6, the extrusion plate 5 will move downward.

[0041] The bottom end of the extrusion plate 5 is connected to a connecting rod 7, and the bottom end of the connecting rod 7 is connected to a top rod 8. The top rod 8 and the extrusion plate 5 both form a rotating structure with the connecting rod 7, and the top rod 8 and the extrusion plate 5 both form a sliding structure with the fixed block 1. The connecting rod 7 penetrates the inner surface of the groove 9. The groove 9 has two openings at 90° to the outer surface of the cylindrical block 10. The cylindrical block 10 is engaged with the connecting rod 7 through the groove 9. The cylindrical block 10 and the fixed block 1 form a rotating structure. When the extrusion plate 5 moves downward, the extrusion plate 5 will drive the top end of the connecting rod 7 to move downward, so that the connecting rod 7 will drive the top end of the top rod 8 to move, allowing the top rod 8 to be inserted into the groove 9. By engaging with the groove 9, the cylindrical block 10 is prevented from rotating.

[0042] The outer surface of the support block 11 is penetrated by the outer ring block 12. The inner surface of the outer ring block 12 is fixedly provided with a connecting block 13. The connecting block 13 and the outer ring block 12 are both installed inside the fixed block 1 to form a rotating structure. The inner surface of the connecting block 13 is penetrated by the screw 14. The top surface of the screw 14 is connected to the limit block 15. The connecting block 13 and the screw 14 are meshed. When the outer ring block 12 is rotated, the outer ring block 12 will drive the connecting block 13 to rotate, so that the connecting block 13 meshes with the screw 14, allowing the screw 14 to slide.

[0043] The screw 14 forms a sliding structure with the support block 11 through the limiting block 15. The screw 14 passes through the bottom surface of the support block 11. A fixing plate 17 is fixedly connected to the bottom surface of the screw 14. A second roller 18 is fixedly installed on the bottom surface of the fixing plate 17. A first roller 16 is fixedly installed on one side surface of the support block 11. When the screw 14 slides, it will drive the limiting block 15 to move. The limiting block 15 prevents the screw 14 from sliding out. The sliding of the screw 14 will also drive the fixing plate 17 to slide, so that the second roller 18 on the fixing plate 17 will also move. The whole can be moved by the second roller 18 or the first roller 16.

[0044] A push plate 19 is fixedly installed on one side surface of the support block 11. The push plate 19 is located below the extrusion block 20, which is located inside the fixed block 1. One end of the extrusion block 20 is connected to a guide rod 21, and the end of the guide rod 21 is connected to a detection camera 22. The detection camera 22 penetrates the bottom surface of the fixed block 1, and the output end of the detection camera 22 is connected to the input end of the display screen 4. When the support block 11 is driven to rotate, the push plate 19 on the support block 11 also rotates, thereby extruding the extrusion block 20.

[0045] Both the detection camera 22 and the squeezing block 20 form a rotating structure with the guide rod 21, and both the detection camera 22 and the squeezing block 20 form a sliding structure with the fixed block 1. A support spring 23 is fixedly connected to the outer surface of the detection camera 22. The support spring 23 is fixedly installed inside the fixed block 1. The fixed block 1 and the detection camera 22 form an elastic structure through the support spring 23. When the squeezing block 20 is squeezed, the squeezing block 20 will drive the top end of the guide rod 21 to move, so that the end of the guide rod 21 can drive the detection camera 22 to move. Thus, when the detection camera 22 moves downward, it can compress and charge the support spring 23 and slide out of the fixed block 1, which facilitates detection.

[0046] Working principle: When using this crack detection device for bridge pavement, connect the device to its built-in power supply, and according to... Figure 1-7 First, after moving the device to the desired location via the second roller 18, the pressing plate 5 under the action of the return spring 6 is pulled, causing the pressing plate 5 to slide upwards. The pressing plate 5 effectively wipes and protects the display screen 4 on the protective plate 3, preventing it from being bumped. Simultaneously, the pressing plate 5 pulls the top rod 8 out of the groove 9 via the connecting rod 7, allowing the support block 11 to rotate via the cylindrical block 10. After rotating 90°, the pressing plate 5 under the action of the return spring 6 is released. The pressing plate 5 then pushes the top rod 8 into the groove 9 via the connecting rod 7 to re-engage, preventing the support block 11 from rotating via the cylindrical block 10. At this time, the first roller 16 on the support block 11 connects... Upon contact with the ground, the device moves via the first roller 16. Simultaneously, the rotation of the support block 11 causes the push plate 19 to press against the compression block 20. The compression block 20 then pushes out the detection camera 22, protected by the support spring 23, via the guide rod 21. This effectively brings the detection camera 22 closer to the ground for crack detection, which is then displayed on the screen 4. At the same time, rotating the outer ring block 12 causes the connecting block 13 to engage with the screw 14, allowing the screw 14 to slide through the limit block 15. This pushes the fixing plate 17, enabling the second roller 18 on the fixing plate 17 to conform to the inner wall of the bridge, assisting the entire device in linear movement and preventing deviation, thus increasing its overall practicality.
