Technical Field

[0001] This utility model relates to a precise measurement device for smart construction based on BIM technology, belonging to the field of BIM construction measurement technology. Background Technology

[0002] BIM technology is a data-driven tool applied to engineering design, construction, and management. The core of BIM is to create a virtual 3D model of a building project and use digital technology to provide this model with a complete and realistic building project information database. This database not only contains geometric information, professional attributes, and status information describing building components, but also status information of non-component objects, such as spatial and motion behavior. With the help of this 3D model containing building project information, the level of information integration of building projects is greatly improved, thereby providing a platform for the exchange and sharing of engineering information for relevant stakeholders in building projects.

[0003] In BIM technology, all relevant information and data of building construction projects are collected by various information collection and surveying devices. Currently, in the construction environment, precise measuring devices need to be fixed on a base surface. However, it is not easy to find a flat base surface in the construction environment. Moreover, precise measuring devices are prone to shaking and loss of balance in the construction environment, which will affect the subsequent measurement results.

[0004] Therefore, there is an urgent need to improve a precise measurement device for smart construction based on BIM technology to solve the aforementioned problems. Utility Model Content

[0024] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown in the figure, this embodiment provides an example of a precise measurement device for smart construction based on BIM technology.

[0026] A precision measurement device for smart construction based on BIM technology includes a base 1, with multiple legs 2 fixedly installed at the bottom of the base 1. Each leg 2 has a caster wheel 3 at its bottom. A 3D measuring instrument 4 is mounted above the base 1. A BIM model data controller 5, electrically connected to the 3D measuring instrument 4, is mounted on one side of the instrument. A stable support mechanism 6 is mounted on the base 1. The stable support mechanism 6 includes a fixed plate 7 fixedly installed at the bottom of the base 1. A first hydraulic rod 8 is fixedly installed at the bottom of the fixed plate 7. A first support frame 9 is fixedly installed on the fixed plate 7. A second support frame 10 is movably installed at the bottom of the first support frame 9 and connected to the output end of the first hydraulic rod 8. A first motor 11 is fixedly installed at the bottom of the second support frame 10. A drill rod 12 is mounted on the first motor 11. Second hydraulic rods 13 are fixedly installed around the fixed plate 7. A support plate 14 is fixedly installed at the output end of the second hydraulic rods 13. A level 15 is fixedly installed on the surface of the base 1. By setting up a stable support mechanism 6, the base 1 can be placed in a balanced manner in the construction environment. First, multiple second hydraulic rods 13 are connected to external hydraulic pumps and control units. The control unit controls the extension and retraction of the second hydraulic rods 13, so that the support plate 14 on the output end of each second hydraulic rod 13 contacts the ground. Then, according to the calibration of the level 15, the extension and retraction of the second hydraulic rods 13 are adjusted one by one until the base 1 is adjusted to a horizontal state. After the adjustment and placement are completed, the first hydraulic rod 8 is connected to external hydraulic pumps and control units. The first hydraulic rod 8 is started so that its output end pushes the second support frame 10 down, and the first motor 11 is started to rotate the drill rod 12. During the descent, the drill rod 12 drills deep into the ground to make a tight connection, which can effectively fix the base 1 as a whole, thereby preventing the 3D mapping instrument 4 on the base 1 from shaking during the measurement process and avoiding affecting the measurement results.

[0027] In this embodiment, as Figures 1-6As shown, a first groove 16 is provided on the top of the base 1. A second motor 17 is fixedly installed inside the first groove 16. A turntable 18 connected to the bottom of the 3D mapping instrument 4 is fixedly installed at the output end of the second motor 17. Multiple support wheels 19 are fixedly installed at the bottom of the turntable 18. A second groove 20 is provided on the base 1. Multiple fixing rods 21 are symmetrically fixedly installed at the bottom of the base 1. Foot pedals 22 are fixedly installed on the fixing rods 21. Connecting shafts 23 are fixedly installed around the base 1. Protective frames 24 are movably installed on the connecting shafts 23. Multiple magnetic blocks 25 are fixedly installed on the protective frames 24. Through the arrangement of the first groove 16, the second motor 17, the turntable 18, the support wheels 19, and the second groove 20, starting the second motor 17 enables the turntable 18 to rotate, and with the support of multiple support wheels 19, the turntable 18 rotates on top of the base 1. The rotation of the turntable 18 synchronously drives the 3D mapping instrument 4 to rotate, thereby adjusting the angle of the 3D mapping instrument 4 to perform scanning measurements at different angles, improving the completeness of the measurement and making the BIM model more accurate. Through the setting of the fixing rod 21 and the foot pedal 22, the operator can use their foot to pedal while drilling with the drill rod 12. The foot pedal 22 applies downward pressure to the base 1, thereby enabling the drill rod 12 to drill more effectively and preventing the base 1 from being lifted up in reverse during drilling. Through the connection shaft 23, the protective frame 24 and the magnetic block 25, multiple protective frames 24 are pushed to flip and merge by the connection shaft 23 and are fixed by the attraction of multiple magnetic blocks 25. The merged protective frame 24 can completely enclose the 3D mapping instrument 4, thus providing protection and preventing it from being bumped during storage. At the same time, when measuring, the multiple protective frames 24 are unfolded outward to form a barrier, preventing personnel from approaching during measurement.

[0028] In this embodiment, as Figures 1-6As shown, a telescopic rod 26 is fixedly installed on one side of the fixed rod 21, a first pad 27 is fixedly installed at the output end of the telescopic rod 26, a second pad 28 is fixedly installed on the surface of the protective frame 24, a first flange 29 is fixedly installed on the first motor 11, a second flange 30 is fixedly installed on the drill rod 12, multiple bolts are installed between the first flange 29 and the second flange 30, multiple springs 31 are fixedly installed between the support leg 2 and the moving wheel 3, and shock absorbers 32 installed on the support leg 2 and the moving wheel 3 are provided between the multiple springs 31. With the telescopic rod 26, the first pad 27, and the second pad 28, after the multiple protective frames 24 are flipped and unfolded, the telescopic rod 26 is pulled to extend it and move the first pad 27 until it extends to below the second pad 28. After the first pad 27 contacts the second pad 28, it can provide stable support for the unfolded protective frame 24. With the first flange 29, the second flange 30, and the bolts, the first motor 11 and the drill rod 12 are fixed together by the connection of the first flange 29, the second flange 30, and the bolts, so that the drill rod 12 can be disassembled from the output end of the first motor 11, which facilitates replacement when the drill rod 12 is damaged or broken. With the spring 31 and the shock absorber 32, when the base 1 travels on the uneven construction road surface, the buffer of the spring 31 and the damping of the shock absorber 32 work together to reduce the vibration of the base 1, effectively reducing the damage caused by vibration to the 3D mapping instrument 4.

[0029] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the precision measurement device for smart construction based on BIM technology provided in this embodiment is as follows:

[0030] First, move the base 1 to the measurement location, flip the multiple protective frames 24 to expose the 3D measuring instrument 4, then connect multiple second hydraulic rods 13 to external hydraulic pumps and control units. Control the extension and retraction of the second hydraulic rods 13 through the control unit, so that the support plate 14 on the output end of each second hydraulic rod 13 contacts the ground. Then, according to the calibration of the level 15, adjust the extension and retraction of the second hydraulic rods 13 one by one until the base 1 is adjusted to a horizontal state. At the same time, after the adjustment and placement are completed, apply downward pressure to the base 1 by stepping on the foot pedal 22 through the gap between the multiple protective frames 24. Then connect the first hydraulic rod 8 to external hydraulic pumps and control units, start the first hydraulic rod 8 so that its output end pushes the second support frame 10 down, and start the first motor 11 to adjust the drill rod 12 to rotate. During the descent, the drill rod 12 drills deep into the ground to make a tight connection, which can effectively fix the base 1 as a whole. After the base 1 is fixed, the 3D measuring instrument 4 can be started to measure the BIM model.
