Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, and in particular to a modular assembled bridge inspection device. Background Technology

[0002] With the acceleration of industrialization and urbanization, the number and scale of various bridges, including highway bridges, railway bridges, and urban viaducts, have increased dramatically. However, under the long-term effects of loads, environmental erosion such as acid rain and salt spray, and traffic vibrations, bridges are prone to structural cracks, steel corrosion, and bearing aging, directly threatening traffic safety. Traditional bridge inspection methods rely on manual climbing, scaffolding, or simple rope hoisting, which are not only inefficient and labor-intensive but also pose serious safety hazards for working at heights, especially since they are difficult to comprehensively cover complex structures such as long-span and high-pier bridges.

[0003] While existing bridge inspection vehicles possess significant advantages, such as replacing dangerous manual climbing with liftable booms and platforms to quickly cover all parts of the bridge, thus improving inspection efficiency and safety, and integrating high-precision sensors and cameras for real-time data acquisition and accurate detection, they still have certain limitations: high equipment purchase costs and large initial investments; operators need systematic training to skillfully operate the complex robotic arms, hydraulic systems, and inspection equipment; the large size of the equipment makes it susceptible to space constraints when operating on urban roads or in busy traffic areas, requiring coordination with traffic control and potentially interfering with normal traffic flow; and high maintenance costs, requiring regular professional maintenance of the hydraulic systems, sensors, and inspection equipment, with mechanical failures easily leading to inspection interruptions and affecting project schedules. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of high cost, complex operation, large size and high maintenance cost of existing bridge inspection equipment, and to propose a modular assembled bridge inspection equipment.

[0005] To achieve the above objectives, the present invention employs the following technology: a modular assembled bridge inspection device, comprising a platform, the bottom of which is fixed to the bridge ground by a detachable suction cup base, and the top of which is provided with a base capable of circumferentially rotating around the axis of the platform via a detachable rotary mechanism. A slide seat capable of moving along the axis of the truss beam is provided on the truss beam of the base via a drive mechanism, and a basket mechanism is detachably provided at the bottom of the slide seat via a lifter assembled and connected thereto.

[0006] As a further description of the above technical solution: the positioning plate of the platform body is provided with positioning holes that cooperate with the pre-embedded bolts on the suction cup base, and the suction cup base is provided with reinforcing bolts that are threadedly connected to the platform body along the direction perpendicular to the axis of the platform body.

[0007] As a further description of the above technical solution: the rotary mechanism includes a rotary drive, the bottom of which is bolted to the flange on the top of the platform via a connecting seat, and the drive shaft of the rotary drive is detachably connected to the base via a connecting plate.

[0008] As a further description of the above technical solution: the truss beam is a box-shaped hollow structure.

[0009] As a further description of the above technical solution: the drive mechanism includes a motor unit installed in the base, and a screw arranged along the axis of the truss beam is provided on its output end, and a drive seat is provided on the screw that is threadedly engaged with it and connected to the slide.

[0010] As a further description of the above technical solution: the driving mechanism also includes a pair of guide rails arranged parallel to the screw, and a sliding sleeve that is detachably connected to the slide block is slidably connected on the guide rails.

[0011] As a further description of the above technical solution: the suspended platform mechanism includes a platform with a fence, a control box and a control panel electrically connected to the control box are installed on the fence via baffles.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. Modular design breaks down the equipment into multiple relatively independent components, reducing its size and weight, making it adaptable to different transportation tools, reducing transportation difficulty and costs, and allowing the components to be compactly arranged during transportation, reducing space occupation;

[0014] 2. With a modular design, each component has a clear function and can be assembled with simple bolt connections. Portable assembly makes the installation process more convenient, without the need for complex and large tools. Construction personnel can quickly complete the equipment setup or disassembly, greatly shortening preparation and finishing time and improving work efficiency.

[0015] 3. No need for specialized heavy lifting equipment and a large number of construction personnel, reducing dependence on on-site conditions. This advantage is more pronounced in bridge inspection sites with limited space or complex terrain, and can also reduce labor costs and construction risks.

[0016] 4. When a module malfunctions or is damaged, it can be disassembled and replaced individually without the need for overall repair or equipment replacement, thus shortening repair time and reducing repair costs. The spare module can quickly replace the faulty module, ensuring the continuity of testing work.

[0017] 5. Modular design allows manufacturers to mass-produce universal modules, reducing the production cost of individual modules. Users also do not need to pay high fees for unnecessary overall functions. They can select modules as needed, saving procurement funds and reducing procurement costs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5This embodiment provides a modular assembled bridge inspection device, including a platform 1. The bottom of the platform 1 is fixed to the bridge ground by a detachable suction cup base 2, and the top of the platform 1 is provided with a base 4 that can rotate circumferentially around the axis of the platform 1 by a detachable rotary mechanism 3. The rotary mechanism 3 includes a rotary driver 31, the bottom of which is bolted to the flange at the top of the platform 1 by a connecting seat 32. The drive shaft 33 of the rotary driver 31 is detachably connected to the base 4 by a connecting plate 34. A slide 7 that can move along the axis of the truss beam 5 is provided on the truss beam 5 by a drive mechanism 6, and a basket mechanism 9 is detachably provided on the bottom of the slide 7 by a lifting device 8 assembled and connected to it.

[0027] In this utility model, the suction cup base 2 at the bottom of the platform 1 adopts a vacuum pump suction cup structure. When conducting bridge inspection work, after selecting a position on the bridge ground, the suction cup base 2 is connected to the bottom of the platform 1. The vacuum pump is started to make the suction cup adsorb the ground and provide stable support. Then, the rotary mechanism 3 is installed on the top of the platform 1 and the base 4 is connected to the rotary mechanism 3. The rotary driver 31 serves as the power source (the rotary driver 31 adopts the WB120 model). After the internal worm gear structure is started, electrical energy is converted into mechanical energy, causing the drive shaft 33 to rotate. This causes the base 4 to drive the truss beam 5 to rotate 360° around the axis of the platform 1, so that the axis of the beam is at a suitable angle with the side of the bridge and the inspection position is determined.

[0028] After the detection location is determined, the drive mechanism 6 is activated. The drive mechanism 6 includes a motor unit 61 installed in the base 4. A screw 62, arranged along the axis of the truss beam 5, is mounted on its output end. A drive seat 63, threadedly engaged with the screw 62 and connected to the slide 7, is mounted on the screw 62. When the motor unit 61 is activated, its output shaft drives the screw 62 to rotate. Because the drive seat 63 is threadedly engaged with the screw 62, the rotation of the screw 62 causes the drive seat 63 to move along the axial direction of the screw 62, thereby driving the slide 7 to move along the axis of the truss beam 5, thus raising the suspended platform. Mechanism 9 is horizontally positioned above the target detection point. Then, the hydraulic cylinder of the lifting device 8 operates, driving the basket mechanism 9 to rise and fall vertically. Depending on the height of the detection part, it is adjusted to the optimal working range of 0.5-2 meters from the detection surface. It should be noted that the lifting device 8 adopts a hydraulic parallelogram telescopic lifting mechanism commonly used in existing technology. Its principle is that when the piston rod of the hydraulic cylinder extends or retracts, it will push one side of the parallelogram to move. Due to the characteristic that opposite sides of the parallelogram are always parallel and equal, the other sides will move accordingly, causing the entire parallelogram structure to change shape and achieve vertical telescopic changes.

[0029] The suspended platform mechanism 9 includes a platform 91 with a fence 92. A control box 94 is installed on the fence 92 via a baffle 93, and a control panel 95 is electrically connected to the control box 94. When the inspection personnel operate on the platform 91, through the cooperation of the control panel 95 and the control box 94, the inspection personnel can centrally control and monitor the entire bridge inspection equipment within the suspended platform mechanism 9, understand the operating status of the equipment in real time, and adjust the working parameters of the equipment in a timely manner to ensure the smooth progress of the inspection work.

[0030] In addition, to ensure the stable movement of the drive seat 63 and the slide 7, the drive mechanism 6 also includes a pair of guide rails 64 arranged parallel to the screw 62, and a sliding sleeve 65 detachably connected to the slide 7 is slidably connected to the guide rails 64. The sliding sleeve 65 is slidably connected to the guide rails 64, so that the slide 7 can slide smoothly along the axis of the truss beam 5 under the drive of the drive seat 63, avoiding deviation or shaking during movement.

[0031] The entire testing equipment adopts a modular assembly design, which breaks the equipment down into multiple independent parts, making it easy to transport and reducing transportation costs. It is also easy to assemble without the need for large tools, which can significantly shorten the installation and disassembly time, improve work efficiency, reduce dependence on construction sites and specialized equipment, reduce labor costs and construction risks, facilitate maintenance, and save maintenance and procurement costs.

[0032] It should be noted that the truss beam 5 is a box-shaped hollow structure. The box-shaped hollow truss beam 5 has high bending and torsional stiffness, which can effectively distribute and bear various loads generated during equipment operation, such as the dynamic load when the slide 7 moves and the gravity when the basket mechanism 9 is fully loaded. Compared with a solid structure, with the same amount of material, the box-shaped hollow structure has a larger moment of inertia and stronger resistance to deformation, thereby ensuring the stability of the entire equipment during testing operations and reducing testing errors or safety hazards caused by beam deformation.

[0033] Specifically, the positioning plate 11 of the platform body 1 is provided with positioning holes that cooperate with the pre-embedded bolts 21 on the suction cup base 2, and the suction cup base 2 is provided with reinforcing bolts 22 that are threadedly connected to the platform body 1 along the direction perpendicular to the axis of the platform body 1.

[0034] During installation, the bottom of the platform 1 is inserted into the mounting slot of the suction cup base 2. The positioning hole of the positioning plate 11 of the platform 1 is aligned with the pre-embedded bolt 21 of the suction cup base 2 to quickly complete the initial positioning. Then, the reinforcing bolt 22 perpendicular to the axis of the platform 1 is rotated and tightened. The threaded connection makes the platform 1 and the suction cup base 2 fit tightly together. The positioning hole and the pre-embedded bolt 21 cooperate to ensure accurate installation and reduce alignment time. The reinforcing bolt 22 enhances the connection strength and resists external forces such as shear force and torque during equipment operation, preventing the platform 1 from shifting or shaking during the testing process. This provides a guarantee for the stable operation of the upper rotation and movement mechanisms, and improves the overall stability and safety of the equipment.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
