Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering data acquisition technology, and more specifically, to a BIM-based building engineering data acquisition device. Background Technology
[0002] BIM, also known as Building Information Modeling, is a complete information model that integrates engineering information, processes, and resources at different stages throughout the entire life cycle of an engineering project into a single model. It is convenient for all parties involved in the project to use, and through three-dimensional digital technology, it simulates the real information of a building, providing a coordinated and internally consistent information model for engineering design and construction.
[0003] Chinese utility model patent application publication CN221483270U A BIM-based building engineering data acquisition and simulation device disclosed in the paper, although it can buffer the mounting box and the electronic components above through the set moving mechanism, solve the problem of internal vibration caused by uneven ground during movement, and increase the service life of the device, the protection of the device during use is limited to vertical vibration reduction. However, the vibration during the movement of the device is multi-angle and all-round, resulting in poor protection effect. In addition, when the device is used on an inclined ground, the entire device is also in an inclined state, making it difficult to straighten the probe. The information data collected under this condition often has a large deviation, which seriously affects the subsequent model calculation and splicing. Therefore, the present invention has the disadvantages of not being convenient for all-round vibration reduction and not being convenient for automatic leveling of the probe. Utility Model Content

[0013] (III) Beneficial Effects
[0014] Compared with existing technologies, this utility model provides a BIM building engineering data acquisition device, which has the following beneficial effects:
[0015] 1. This BIM building engineering data acquisition device, through the arrangement of a first ball head, a first ball head, a support rod, a top plate, a shock-absorbing spring, a first rubber block, a second rubber block, a steel wire rope, a counterweight ball, and a hydraulic cylinder, enables the BIM building engineering data acquisition device to provide all-round seismic protection for cameras and BIM probes. The coordinated arrangement of the support rod, top plate, shock-absorbing spring, first rubber block, second rubber block, steel wire rope, and counterweight ball provides high-quality vertical vibration damping during use. The coordinated arrangement of the first ball head, first ball head, support rod, steel wire rope, counterweight ball, and hydraulic cylinder allows the support rod to rotate freely during use, and the steel wire rope provides a flexible connection between the support rod and the counterweight ball, allowing the vibration damping structure to better accommodate vibrations at different angles, thus achieving the purpose of omnidirectional vibration damping.

[0027] Please see Figures 1-6A BIM (Building Information Modeling) data acquisition device includes a remote-controlled tracked vehicle 1. An installation platform 2 is mounted on the upper surface of the tracked vehicle 1. A bracket 3 is mounted on the upper surface of the installation platform 2. A first ball joint 4 is fixedly connected to one end of the bracket 3. A first ball joint 5 is movably connected to the inner wall of the first ball joint 4. A support rod 6 is inserted into the inner wall of the first ball joint 5. A support plate 7 is fixedly connected to one end of the support rod 6. A camera 8 and a BIM detector 9 are fixedly connected to the lower surface of the support plate 7. A steel wire rope 14 is fixedly connected to the lower end of the support rod 6. A counterweight ball 15 is fixedly connected to the lower end of the steel wire rope 14. A protective tube 22 is fixedly connected to the outer surface of the steel wire rope 14. A protective tube 22 is fixedly connected to the inner wall of the installation platform 2. A rubber pad 23 and a top plate 10 are fixedly connected to the outer surface of the support rod 6. A shock-absorbing spring 11 abuts against the lower surface of the top plate 10. A first rubber block 12 is fixedly connected to the lower surface of the top plate 10. A groove adapted to the shock-absorbing spring 11 is opened on the outer surface of the first rubber block 12. The outer surface of the shock-absorbing spring 11 is tightly connected to the inner wall of the groove. A second rubber block 13 is fixedly connected to the lower end of the shock-absorbing spring 11. The lower surface of the second rubber block 13 abuts against the upper surface of the first ball head 5. A battery and a main control module are installed inside the mounting platform 2. The support rod 6 has a hollow structure inside. The battery, main control module, support plate 7 and BIM probe 9 are all electrically connected by wires that pass through the inside of the support rod 6.
[0028] Specifically, the first ball joint 4 and the first ball joint 5 are connected movably, allowing the support rod 6 to rotate freely at any angle, converting multi-angle vibrations into vertical displacement. The top plate 10, damping spring 11, first rubber block 12, and second rubber block 13 on the outside of the support rod 6 form a vertical elastic buffer structure. The spring is embedded in the groove of the rubber block, consuming vibration energy through deformation and friction. The steel wire rope 14 flexibly connects to the counterweight ball 15, which can swing with the vibration direction, driving the support rod 6 to adjust its angle. Four ring-shaped hydraulic cylinders 17 are connected by a connecting pipe 21. When the counterweight ball 15 swings and squeezes a hydraulic cylinder 17 on one side, the hydraulic oil flows to the hydraulic cylinder 17 on the other side, using hydraulic damping to buffer lateral vibrations. The above structure achieves vibration direction conversion through multiple ball joint hinges, weakens vertical vibrations through the elastic friction between the spring and the first rubber block 12 and the second rubber block 13, and buffers multi-directional vibrations with the flexible traction of the steel wire rope 14 and the damping of the hydraulic system, together forming an all-round vibration reduction system, effectively protecting the camera 8 and the BIM probe from multi-dimensional vibration interference and improving the stability of data acquisition.
[0029] Please see Figures 1-6The bracket 3 is fixedly connected to the middle of a second ball head seat 16. The inner wall of the second ball head seat 16 is rotatably connected to a hydraulic cylinder 17 via a second ball head 18. The outer surface of the counterweight ball 15 is fixedly connected to a third ball head seat 20. One end of the telescopic rod of the hydraulic cylinder 17 is rotatably connected to the inner wall of the third ball head seat 20 via a third ball head 19. The bracket 3 is provided with four cylinders evenly distributed in a circular array. The hydraulic cylinders 17 are also provided with four cylinders evenly distributed in a circular array. Two hydraulic cylinders 17 are connected by a connecting pipe 21. The inside of the hydraulic cylinders 17 and the inside of the connecting pipe 21 are filled with hydraulic oil. The bracket 3 is provided with four cylinders evenly distributed in a circular array. The hydraulic cylinders 17 are also provided with four cylinders evenly distributed in a circular array. Two hydraulic cylinders 17 are connected by a connecting pipe 21. The inside of the hydraulic cylinders 17 and the inside of the connecting pipe 21 are filled with hydraulic oil.
[0030] Specifically, the counterweight ball 15 pulls down the support rod 6 via the steel wire rope 14, using gravity to make the support rod 6 tend towards the vertical direction; the movable connection between the first ball head seat 4 and the first ball head 5 allows the support rod 6 to rotate with the counterweight ball 15 until it is perpendicular to the horizontal plane; the four hydraulic cylinders 17 are hinged to the bracket 3 and the counterweight ball 15 via the second ball head seat 16 and the third ball head seat 20. When the device is tilted, the lower hydraulic cylinder 17 is squeezed by the counterweight ball 15, and the hydraulic oil flows into the higher hydraulic cylinder 17 through the connecting pipe 21, pushing the higher telescopic rod to extend, forming a reverse thrust to assist the support rod 6 in returning to the upright position. The gravity traction of the counterweight ball 15 and the ball head hinge structure work together to make the support rod 6 automatically tend towards the vertical on the tilted ground; the hydraulic system generates a dynamic balance thrust through the oil flow in the connecting pipe 21, which accelerates the leveling process and suppresses shaking, ensuring that the camera 8 and the BIM probe are always perpendicular to the ground, avoiding data acquisition deviations caused by device tilt, and improving the accuracy of BIM model calculation and splicing.
[0031] In summary, when the overall equipment is in use: the tracked vehicle 1 is remotely controlled by a remote controller, and the surrounding environment is captured by a camera 8. When traveling on bumpy sections, the support rod 6 is pulled down by the steel wire rope 14 and the counterweight ball 15. At this time, the support rod 6 can move up and down inside the first ball head 5. When the support rod 6 moves up and down, it will compress the shock-absorbing spring 11 through the top plate 10. The deformation of the shock-absorbing spring 11 will also rub against the first rubber block 12, compressing the first rubber block 12. Similarly, the lower end of the shock-absorbing spring 11 will also compress the second rubber block 13, thereby allowing the first rubber block 12 and the second rubber block 13 to absorb the energy of vibration and achieve a shock-absorbing effect. The setting of the first ball head seat 4 and the first ball head 5 allows the support rod 6 to rotate in all directions, thereby preventing the support rod from rotating in any direction. Vibrations at the same angle are all converted into a vertical state, and then weakened by the first rubber block 12 and the second rubber block 13. When the counterweight ball 15 swings to one side, the telescopic rod of the hydraulic cylinder 17 in that direction will be squeezed and contracted. Through the setting of the connecting pipe 21, the hydraulic oil in the hydraulic cylinder 17 will flow to the hydraulic cylinder 17 opposite to that direction, causing the telescopic rod of the hydraulic cylinder 17 to extend. Since the flow speed of the hydraulic oil is limited, the impact force of the counterweight ball 15 in a certain direction will be absorbed by the flow of hydraulic oil, thus achieving the shock absorption effect. The steel wire rope 14 and the counterweight ball 15 pull the support rod 6 to rotate relative to the first ball head 5 at the first ball head seat 4. When the device is in an inclined position, the support rod 6 will also be in a vertical state after a short period of shaking, improving the accuracy of the data collected by the BIM detector head 9.

For all the fixed connections mentioned above, welding is preferred.
