Technical Field

[0001] The invention relates to the technical field of bridge detection equipment, and in particular to a bridge structure damage identification and detection device. Background Art

[0002] With the continuous development of transportation infrastructure, bridges, as important transportation hubs, are of vital importance for their safety and reliability. In order to timely detect damage to bridge structures and avoid potential safety hazards, bridge structure damage identification and detection devices have emerged. At present, the existing bridge structure damage identification and detection devices on the market have met the needs of bridge structure detection to a certain extent, but with the continuous development of bridge construction and the continuous improvement of detection accuracy requirements, the existing detection devices have gradually exposed some shortcomings.

[0003] Existing bridge structure damage identification and detection devices usually use traditional detection methods, such as manual inspection, sensor monitoring, etc. Structurally, they are generally composed of detection equipment, mobile platforms, and data processing systems. The detection equipment mainly includes various sensors and scanners, which are used to collect physical parameters and image information of the bridge structure. The data processing system analyzes and processes the collected data to determine whether the bridge structure is damaged.

[0004] In actual use scenarios, existing bridge structure damage identification and detection devices have some problems. For example, in the inspection of some large bridges, existing devices often need to be pushed manually or moved with the help of large mechanical equipment, which is inconvenient to operate and inefficient. This is because the traditional mobile platform design is not flexible enough and cannot achieve automatic movement, which requires a lot of manpower and time. In addition, during the inspection process of the existing detection device, gravel and impurities on the bridge deck will interfere with the normal operation of the detection equipment and affect the accuracy of the detection results. Therefore, the present invention provides a bridge structure damage identification and detection device to solve the shortcomings of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please refer to the attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a bridge structure damage identification and detection device, including a main body plate 1. The main body plate 1 is the main bearing structure of the entire device, and provides a foundation for installation and support for other components. A guardrail is fixedly connected to the top of the main body plate 1, and the guardrail plays a protective role to prevent the operator from accidentally falling during work. A guide rod 20 is fixedly connected to the inner side of the guardrail, and the guide rod 20 provides a guide for the mounting seat 11 in the cleaning mechanism to ensure that the mounting seat 11 maintains a stable direction during the reciprocating movement. The outside of the main body plate 1 is rotatably connected to a reciprocating screw rod 9, which is an important component of the cleaning mechanism, and drives the mounting seat 11 to reciprocate through its rotation. Two groups of fixed blocks 2 are fixedly connected to the bottom of the main body plate 1, and the number of each group of fixed blocks 2 is two, and the fixed blocks 2 provide a stable installation position for the axle 3. The inside of each group of fixed blocks 2 is rotatably connected to the axle 3, and the wheel 4 is installed on the axle 3. The inner ring concave design of the wheel 4 plays an important role. This design reduces the contact area between the wheel 4 and the ground. On the one hand, it reduces the resistance of the wheel 4 when rolling, making the overall device easier and more labor-saving when moving; on the other hand, the use of rubber to increase friction ensures that the overall device can move stably on the bridge surface without slipping. A cleaning mechanism is arranged on the outside of the main plate 1, and the cleaning mechanism includes a driving assembly and a disassembly assembly. The driving assembly includes a motor 5, which is installed at the bottom of the main plate 1, and the motor 5 provides a power source for the entire cleaning mechanism. A worm 7 is fixedly connected to the output end of the motor 5, and a worm wheel 8 is fixedly connected to the outside of one of the axles 3, and the worm 7 is meshed with the worm wheel 8. When the motor 5 is started, the worm 7 is driven to rotate, and then the worm wheel 8 is driven to rotate, so that the axle 3 rotates, thereby realizing the rotation of the wheel 4, so that the overall device moves automatically for detection. A protective box 6 is fixedly connected to the bottom of the main plate 1, and the worm wheel 8 is arranged inside the protective box 6. The protective box 6 plays a role in protecting the worm wheel 8 and the worm 7 to prevent them from being hit and damaged by the outside. The reciprocating screw rod 9 and one end of the axle 3 close to the motor 5 are fixedly connected with a pulley 10, and a belt is sleeved on the outer circumference of the two pulleys 10. The rotation of the axle 3 is transmitted to the reciprocating screw rod 9 through the transmission of the pulley 10 and the belt, so that the reciprocating screw rod 9 rotates.

[0025] Specifically, first, push the whole device to the bridgehead. This step is relatively simple, and only requires manual movement of the device to the bridgehead position where the inspection is required. This ensures that the device starts working at the appropriate position and is ready for subsequent inspection work. Then start the motor 5 to drive the worm 7 to rotate. As a power source, the motor 5 can provide a stable driving force. When the motor 5 is started, its output end drives the worm 7 to rotate. The rotation of the worm 7 then causes the worm wheel 8 to drive the axle 3 to rotate. The cooperation of the worm wheel 8 and the worm 7 has a certain deceleration and torque increase effect, which can convert the high-speed rotation of the motor 5 into a suitable speed of the axle 3, so that the wheel 4 rotates to realize the automatic movement of the whole device for inspection work. The inner ring concave design of the wheel 4 reduces the contact area with the ground, which can reduce the friction of the device during the movement, so that the device can move more easily on the bridge deck. At the same time, the use of rubber to increase the friction can ensure that the device will not slip during the movement, ensuring the stability and safety of the device. Then, when the whole device moves, the reciprocating screw 9 is driven by the belt transmission through two pulleys 10. The transmission method of the pulley 10 and the belt is simple and reliable, and can transmit the rotation of the axle 3 to the reciprocating screw 9. The rotation of the reciprocating screw 9 causes the cleaning mechanism to reciprocate. The bristle brush at the bottom of the brush plate 14 can clean the gravel and impurities on the bridge deck that is moving forward as a whole. The effect of this is to reduce the complexity of the road surface and avoid affecting the data collection of the scanning device 23. If there are a lot of gravel and impurities on the bridge deck, it will interfere with the detection results of the scanning device 23 and cause inaccurate detection. Through the cleaning of the cleaning mechanism, it can be ensured that the bridge deck is clean and tidy, providing good conditions for the accurate detection of the scanning device 23.

[0026] Please refer to the attached Figure 1 -Attached Figure 4The disassembly assembly includes a mounting seat 11 and a brush plate 14. The mounting seat 11 is threadedly connected to the outside of the reciprocating screw 9. When the reciprocating screw 9 rotates, the mounting seat 11 will reciprocate along the reciprocating screw 9. The inside of the mounting seat 11 is slidably connected to the outside of the guide rod 20, and the guide rod 20 ensures the stability and directionality of the mounting seat 11 during movement. The bottom of the mounting seat 11 is fixedly connected to a combination block 12, and a clamping hole 13 is opened inside the combination block 12. The brush plate 14 is located directly below the mounting seat 11, and the top of the brush plate 14 fits with the bottom of the combination block 12. The top of the brush plate 14 is fixedly connected with a mounting block 15 and a mounting plate 19. A locking rod 16 is slidably connected to the internal through hole of the mounting block 15. A sliding ring 17 is fixedly connected to the outer side of the locking rod 16. One end of the locking rod 16 passes through the clamping hole 13 and is clamped in the internal hole of the mounting plate 19. The brush plate 14 is connected to the mounting seat 11 through the locking rod 16. The other end of the locking rod 16 is fixedly connected with a pull ring, which is convenient for the operator to pull the locking rod 16. A spring 18 is sleeved on the outer side of the locking rod 16. One end of the spring 18 is fixedly connected to the outer side of the sliding ring 17, and the other end of the spring 18 is fixedly connected to the inner wall of the mounting block 15. When the brush plate 14 is installed, the spring 18 is in a compressed state. When the locking rod 16 is clamped in the internal hole of the mounting plate 19, the elastic force of the spring 18 keeps the locking rod 16 in a stable connection state. After the brush plate 14 is worn out after being used for a long time, the lock rod 16 can be pulled out from the inside of the mounting plate 19 and the clamping hole 13 by pulling the pull ring to release the connection state, and the brush plate 14 can be easily removed and replaced.

[0027] Specifically, after the brush plate 14 is worn out after a long period of use, the pull ring can be pulled to extract the lock rod 16 from the inside of the mounting plate 19 and the clamping hole 13 to release the connection state. This operation is very convenient and quick, and no complicated tools are required. The brush plate 14 can be easily removed and replaced to ensure the continuous and effective operation of the cleaning mechanism. If the brush plate 14 is severely worn and not replaced in time, the cleaning effect will be reduced, affecting the working efficiency of the entire device.

[0028] Please refer to the attached Figure 1 -Attached Figure 4, a detection mechanism is provided on the outer side of the main plate 1, and the detection mechanism includes a scanning device 23 and a reciprocating screw 22. The reciprocating screw 22 is rotatably connected to the inside of the main plate 1, and one end of the reciprocating screw 22 and the other end of the reciprocating screw 1 9 are fixedly connected with a pulley 21, and the outer periphery of the two pulleys 21 is provided with a belt. Through the transmission of the pulley 21 and the belt, the reciprocating screw 22 also starts to rotate when the reciprocating screw 1 9 rotates. The outer side of the reciprocating screw 22 is threadedly connected to a moving seat 24, and the outer side of the moving seat 24 is in contact with the inner side of the main plate 1 to ensure the stability of the moving seat 24 during movement. The scanning device 23 is installed at the bottom of the moving seat 24. When the reciprocating screw 22 rotates, the moving seat 24 will drive the scanning device 23 to move back and forth, and collect and detect damage and cracks on the road surface.

[0029] Specifically, after the brush plate 14 is worn out after being used for a long time, the pull ring can be pulled to extract the lock rod 16 from the inside of the mounting plate 19 and the clamping hole 13 to release the connection state. This operation is very convenient and quick, and no complicated tools are required. The brush plate 14 can be easily removed and replaced to ensure the continuous and effective operation of the cleaning mechanism. If the brush plate 14 is severely worn and not replaced in time, the cleaning effect will be reduced, affecting the working efficiency of the entire device. And when the cleaning mechanism is working, the reciprocating screw 1 9 will be driven by the two pulleys 2 21 and the belt to allow the reciprocating screw 2 22 to start rotating. This transmission method can realize the linkage between the cleaning mechanism and the detection mechanism, and improve the working efficiency of the device. Then the moving seat 24 drives the scanning device 23 to move back and forth and collect and detect damage and rupture of the road surface. The reciprocating movement of the scanning device 23 can expand the detection range and ensure comprehensive detection of all parts of the bridge deck. Through the collection and detection of the road surface, the damage and rupture of the bridge structure can be discovered in time, providing an accurate basis for the maintenance and repair of the bridge.

[0030] Working principle: First, push the whole device to the bridge head, then start the motor 5 to drive the worm 7 to rotate, and then the worm wheel 8 drives the axle 3 to rotate, so that the wheel 4 can rotate to realize the automatic movement of the whole device for detection. The inner ring of the wheel 4 is concave to reduce the contact area with the ground, and rubber is used to increase the friction. Then, when the whole device moves, it drives the reciprocating screw 9 to rotate through two pulleys 10 with the help of belt transmission, so that the cleaning mechanism moves back and forth, and the hard brush at the bottom of the brush plate 14 can clean the gravel and impurities on the bridge surface that moves as a whole. Reduce the complexity of the road surface to avoid affecting the data collection of the scanning device 23. After the brush plate 14 is worn out after being used for a long time, the pull ring can be pulled to extract the locking rod 16 from the inside of the mounting plate 19 and the card hole 13 to release the connection state. The brush plate 14 can be easily removed and replaced. When the cleaning mechanism is working, the reciprocating screw 9 will be driven by two pulleys 21 and the belt to allow the reciprocating screw 22 to start rotating, and then the moving seat 24 drives the scanning device 23 to reciprocate and collect and detect damage and cracks on the road surface.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
