Description

Technical Field

[0001] This utility model relates to the field of auxiliary device technology, and in particular to an auxiliary device for road and bridge design and construction based on BIM technology. Background Technology

[0002] BIM technology, or Building Information Modeling technology, is a digital-based approach to managing the entire lifecycle of building projects. It integrates and collaboratively manages various information within a building project by creating and applying a digital model that includes the physical and functional characteristics of the building. This supports efficient decision-making and implementation at every stage of the project, from planning and design to construction and operation and maintenance. Therefore, when designing and constructing roads and bridges, it is necessary to use digital acquisition devices such as cameras or laser scanners to collect information about the surrounding environment of the road and bridge pillars, providing strong support for model building.

[0003] Currently, when collecting information about bridge piers and their surrounding environment, cameras are usually fixed directly to the piers. However, traditional fixing devices are often unable to adapt flexibly to piers of different diameters, resulting in unstable installation or poor compatibility. If only simple binding methods such as rubber bands are used, although they can be temporarily fixed, they are easily damaged by aging and wear during long-term use, which reduces their service life and may even cause them to fall off directly. This makes it impossible to meet the needs of continuous and stable information collection, and their practicality is poor. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies, when fixing cameras for data collection around bridges, are difficult to flexibly adapt to bridge piers of different diameters, thereby reducing the quality and efficiency of data collection. Therefore, this invention proposes a road and bridge design and construction auxiliary device based on BIM technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A road and bridge design and construction auxiliary device based on BIM technology includes multiple fixing sleeves and multiple fixing columns, wherein the multiple fixing sleeves are interconnected through the multiple fixing columns, and further includes:

[0009] Preferably, the fixing component includes a fixing member and a limiting hole. The fixing member is installed at the top of the fourth elastic band near the third elastic band. The limiting hole is disposed through the top of the third elastic band near the fourth elastic band. The fixing member is inserted into the limiting hole, and its bottom end is threaded with a fixing nut. Both the third and fourth elastic bands have mounting holes at their top ends. The two mounting holes are located near the fixing member and the limiting hole, respectively. The plug-in shell is inserted into the two mounting holes.

[0010] Preferably, the first limiting and buffering component includes four limiting blocks and four buffer pads. Two of the limiting blocks are respectively installed at both ends of the elastic band and extend towards the corresponding through groove. Two of the buffer pads are respectively installed on the inner wall of the through groove on the two fixed shells away from the slide groove, and the ends of the two buffer pads near the slide groove are respectively in contact with one side of the two limiting blocks on the elastic band. The other two limiting blocks are respectively installed on the ends of the elastic bands three and four near the elastic band and extend towards the corresponding through groove. The other two buffer pads are respectively installed on the inner wall of the through groove on the fixed shells two and three away from the slide groove, and the ends of the two buffer pads near the slide groove are respectively in contact with one side of the limiting blocks on the elastic bands three and four.

[0011] Preferably, the external tensioning assembly includes two elastic components, which are symmetrically arranged on the fixed sleeve.

The four sliding grooves are respectively opened inside the fixed shell 2, the fixed shell 3, and the two fixed shells 1. Each of the four sliding grooves 2 has a through groove 2 on its outward side. Each of the four sliding grooves 2 is slidably connected to a limit block 2.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1 to 6A road and bridge design and construction auxiliary device based on BIM technology includes multiple fixed sleeves and multiple fixed columns 15. The multiple fixed sleeves are interconnected through the multiple fixed columns 15. Each fixed sleeve consists of a second fixed shell 20, a third fixed shell 21, and two first fixed shells 1.

[0027] The internal tensioning assembly includes two sliding grooves 1 and 2 and two sliding grooves 3 and 9. The two sliding grooves 1 and 2 are respectively installed through one end of two fixed shells 1 and 1, and the two sliding grooves 3 and 9 are respectively installed through one end of fixed shells 20 and 21. The sliding grooves 1 and 2 and the sliding grooves 3 and 9 are internally connected, and both sliding grooves 1 and 2 and the sliding grooves 3 and 9 have a through groove 1 on their inward-facing side. A rubber band 4 is inserted into both sliding grooves 1 and 2, and a rubber band 6 and a rubber band 12 are respectively inserted into the two sliding grooves 3 and 9. Rubber band 4 12 is located inside fixed shell 20 and fixed shell 3 21 respectively, and fixed components are provided on rubber band 3 6 and rubber band 4 12 to connect rubber band 3 6 and rubber band 4 12 to each other.

[0028] The fixing component includes a fixing member 16 and a limiting hole 14. The fixing member 16 is installed at the top of the elastic band four 12 near the position of the elastic band three 6. The limiting hole 14 is provided through the top of the elastic band three 6 near the position of the elastic band four 12. The fixing member 16 is inserted into the limiting hole 14, and its bottom end is threadedly connected to a fixing nut 17. The top of both the elastic band three 6 and the elastic band four 12 are provided with mounting holes 13. The two mounting holes 13 are located near the fixing member 16 and the limiting hole 14, respectively. The plug-in shell 10 is inserted into the two mounting holes 13.

[0029] The first limiting and buffering component includes four limiting blocks 7 and four buffer pads 18. Two limiting blocks 7 are respectively installed at both ends of the elastic band 4 and extend towards the corresponding through groove 1. Two buffer pads 18 are respectively installed on the inner wall of the through groove 1 on the two fixed shells 1 away from the slide groove 3 9, and the ends of the two buffer pads 18 near the slide groove 3 9 are respectively in contact with one side of the two limiting blocks 7 on the elastic band 4. The other two limiting blocks 7 are respectively installed on the ends of the elastic band 3 6 and elastic band 4 12 near the elastic band 4 and extend towards the corresponding through groove 1. The other two buffer pads 18 are respectively installed on the inner wall of the through groove 1 on the fixed shell 2 20 and fixed shell 3 21 away from the slide groove 2, and the ends of the two buffer pads 18 near the slide groove 2 are respectively in contact with one side of the limiting blocks 7 on the elastic band 3 6 and elastic band 4 12.

[0030] The external tensioning assembly includes two elastic components symmetrically arranged on the fixed sleeve. One elastic component is located above the other elastic component. The upper elastic component includes four sliding grooves 2 and 3. The four sliding grooves 2 and 3 are respectively opened inside the fixed shell 20, the fixed shell 3 and 21 and the two fixed shells 1. Each of the four sliding grooves 2 and 3 has a through groove 2 extending outward. Each of the four sliding grooves 2 and 3 has a limiting block 2 connected slidably. The sliding grooves 2 and 3 in the fixed shell 20 and the one of the fixed shells 1 are interconnected. The limiting blocks 2 and 8 in the two sliding grooves 2 and 3 extend in the direction of the corresponding through groove 2 and are jointly fixedly connected to a rubber band 2 and 5. The sliding grooves 2 and 3 in the fixed shell 3 and 31 and the one of the fixed shells 1 are interconnected. The limiting blocks 2 and 8 in the two sliding grooves 2 and 3 extend in the direction of the corresponding through groove 2 and are jointly fixedly connected to another rubber band 2 and 5. The two rubber bands 2 and 5 and the four through grooves 2 and 3 are provided with second limiting buffer components to ensure the stability and durability of the rubber band 2 and 5 during the stretching process.

[0031] The second limiting buffer component includes four buffer pads 19, which are located in four through slots. The opposite ends of two buffer pads 19 on the same side are respectively installed on the inner wall of one end of the corresponding through slot, and the other ends of the two buffer pads 19 are respectively in contact with the limiting block 8 in the corresponding through slot. A ring spring is installed in both the buffer pad 18 and the buffer pad 19.

[0032] In use, the operator first removes the fixing nut 17 threaded at the bottom of each fixing component 16 by twisting it off. Then, the operator pulls the right-side fixing shell 21, causing the elastic band 12 to move upwards, disengaging the fixing component 16 from the limiting hole 14. Next, the device is pulled according to the size of the bridge column to be fixed. Specifically, the fixing sleeve is first unfolded and wrapped around the bridge column, then the two fixing shells 1 are pulled outwards (separating the two fixing shells 1). As the two fixing shells 1 move, the two limiting blocks 7 on the elastic band 4 move and apply pressure to the buffer pads 18 on the two fixing shells 1, stretching the elastic band 4. Next, depending on the size of the bridge pier, the second fixed shell 20 and the third fixed shell 21 are stretched. At this time, the second elastic band 5 will be stretched, and the two limiting blocks 8 on the second elastic band 5 will apply pressure to the buffer pad 19 in the corresponding through groove 2. After completing the above work, the second fixed shell 20 and the third fixed shell 21 are pulled again, and the fixing piece 16 on the fourth elastic band 12 is inserted into the limiting hole 14 in the third elastic band 6. Finally, the fixing nut 17 is tightened on the fixing piece 16 to form a stable ring-shaped fixing structure. During the process of pulling the second fixed shell 20 and the third fixed shell 21, the limiting block 7 on the third elastic band 6 and the fourth elastic band 12 will also apply pressure to the buffer pad 18 on the second fixed shell 20 and the third fixed shell 21.

[0033] The aforementioned buffer pads 18 and 19 provide elastic cushioning and limiting for rubber bands 4, 5, 6, and 12 during the stretching process, thereby ensuring the safety, stability, and durability of each rubber band during stretching adjustment and effectively guaranteeing their service life. The annular springs installed inside buffer pads 18 and 19 further enhance the tensile stability of rubber bands 4, 5, 6, and 12, as well as the limiting strength of buffer pads 18 and 19, through their elastic reaction force.

[0034] After completing the above-mentioned fixing work, insert the plug-in housing 10, which is equipped with multiple cameras 11 (or other digital acquisition devices as needed), into the two mounting holes 13. This design not only ensures the stability of the entire device during the monitoring process, enabling it to accurately and reliably collect bridge data, but also has wide applicability, adapting to bridge piers of different sizes for fixed installation, thereby effectively ensuring the quality and efficiency of data acquisition. Multiple fixing columns 15 can connect multiple fixing sleeves together for integrated monitoring, thereby increasing the monitoring range and improving the comprehensiveness of data acquisition. In addition, the device is extremely convenient in terms of installing, disassembling, and replacing cameras 11, and can flexibly replace other digital acquisition devices according to actual monitoring needs, thereby effectively ensuring the integrity and continuity of monitoring data.

[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.
