Description

Technical Field

[0001] This utility model belongs to the technical field of scanning devices for deep foundation pits, and particularly relates to a scanning device for deep foundation pits. Background Technology

[0002] A deep foundation pit scanning device is a detection device used in deep foundation pit engineering. It typically uses technologies such as lasers and radar to scan the internal structure and deformation of the deep foundation pit to obtain relevant data and ensure the safety and quality of foundation pit construction.

[0003] Most deep foundation pit scanning devices have several drawbacks in use. For example, they require a fixed frame to extend into the deep pit for scanning; during the scanning process, soil may fall onto the device, potentially damaging it and affecting the scan results. Furthermore, most deep foundation pit scanning devices cannot be angled, preventing them from extending vertically into the pit. This necessitates multiple movements and rearrangements of the scanning device, increasing operational complexity and time costs, and reducing scanning efficiency. Therefore, we propose a new deep foundation pit scanning device. Utility Model Content

[0004] The purpose of this invention is to provide a scanning device for deep foundation pits to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a scanning device for deep foundation pits, including a fixing plate and a three-dimensional laser scanner, and further comprising:

[0006] A sliding groove is formed inside a fixed plate, and a sliding column is slidably installed inside the sliding groove. The three-dimensional laser scanner is fixedly installed at the bottom of the sliding column, and a protective cover is fitted on the three-dimensional laser scanner. The protective cover is fixedly connected to the sliding column.

[0007] A driving component, located within a fixed plate, is used to drive the sliding column to slide.

[0008] The base is rotatably mounted on the bottom of the fixed plate. A power cavity is opened in the base. A sliding plate is slidably installed in the power cavity. A limit groove is opened at the bottom of the fixed plate. The upper end of the sliding plate passes through the power cavity and extends into the limit groove. Guide grooves are opened in the limit grooves and on both sides of the sliding plate. Guide posts fixed to the sliding plate are slidably installed in both guide grooves.

[0009] A power assembly, located within the base, is used to drive the sliding plate to slide.

[0010] In this technical solution, when it is necessary to scan a deep foundation pit, the entire device is first placed on top of the deep foundation pit. When the entire device is not in a horizontal state, the sliding plate can be driven to slide through the set power component. The sliding plate drives the fixed plate to rotate upward or downward through two guide columns and two guide grooves to ensure that the entire device is in a horizontal state and that the 3D laser scanner can be vertically extended into the deep foundation pit when in use.

[0011] The drive components allow the sliding column to slide downwards. The sliding column slides on the first fixed column to ensure the stability of the sliding. The sliding column causes the protective cover and the 3D laser scanner to move downwards. The 3D laser scanner emits a laser beam and receives reflected signals to quickly acquire high-precision 3D point cloud data of the foundation pit surface and generate an overall 3D model of the foundation pit. The protective cover ensures that no soil will fall on the 3D laser scanner during operation, thus ensuring the stability of the 3D laser scanner during use.

[0012] In the above technical solution, the driving component further includes:

[0013] A first threaded rod is rotatably mounted in a sliding groove and located at the top of a sliding column. The lower end of the first threaded rod passes through the sliding column and is threadedly connected to the sliding column. The upper end of the first threaded rod passes through the sliding groove and extends to the outside. A first operating disc is fixedly mounted on the top end of the first threaded rod.

[0014] In this technical solution, rotating the first operating disk drives the first threaded rod to rotate. Under the action of the thread, the sliding column slides downward, and the sliding column drives the protective cover and the 3D laser scanner to move downward. The 3D laser scanner quickly acquires high-precision 3D point cloud data of the foundation pit surface by emitting a laser beam and receiving reflected signals, and generates an overall 3D model of the foundation pit. The protective cover ensures that no soil will fall on the 3D laser scanner during operation, thus ensuring the stability of the 3D laser scanner during use.

[0015] In the above technical solution, the power component further includes:

[0016] A worm gear is rotatably mounted inside the power chamber and located on one side of the sliding plate. A second threaded rod is fixedly mounted on one end of the worm gear, and one end of the second threaded rod passes through the sliding plate and is threadedly connected to the sliding plate. A worm is meshed with the bottom of the worm gear, and one end of the worm passes through the power chamber and extends to the outside. A second operating disc is fixedly mounted on one end of the worm. Both the second threaded rod and the worm are rotatably connected to the power chamber.

[0017] In this technical solution, when scanning a deep foundation pit is required, the entire device is first placed on top of the pit. Then, it is checked whether the device is level. If the device is not level, the second operating disc is rotated, which drives the worm gear to rotate. The worm gear drives the worm wheel meshing with it to rotate, and the worm wheel drives the second threaded rod to rotate. Under the action of the thread, the sliding plate slides. The sliding plate drives the fixed plate to rotate upward or downward through two guide posts and two guide grooves. When the device is level, the second operating disc is stopped, ensuring that the 3D laser scanner can be vertically inserted into the deep foundation pit during use.

[0018] In the above technical solution, a second fixing post is further fixedly installed at the bottom of the fixing plate and near the four corners.

[0019] In this technical solution, when scanning a deep foundation pit is required, the entire device is first placed on top of the deep foundation pit, and all four second fixed columns are inserted into the soil to ensure that the entire device will not be displaced during use.

[0020] In the above technical solution, a spirit level is further fixedly installed on the fixing plate.

[0021] In this technical solution, the overall device can be determined by observing the level bubble.

[0022] In the above technical solution, a first fixing post is further fixedly installed inside the sliding groove and at the top of the sliding post. The lower end of the first fixing post passes through the sliding post, and the first fixing post is slidably connected to the sliding post.

[0023] In this technical solution, the sliding column slides on the first fixed column to ensure the stability of the sliding.

[0024] In the above technical solution, two third fixing posts are further fixedly installed inside the power cavity and on one side of the sliding plate. One end of each of the two third fixing posts penetrates the sliding plate and is slidably connected to the sliding plate. The two third fixing posts are respectively located on both sides of the second threaded rod.

[0025] In this technical solution, the sliding plate slides on two third fixed posts to ensure the stability of the sliding plate.

[0026] In the above technical solution, the bottom of the base is further inclined.

[0027] This technical solution ensures that the overall device is suitable for different ground inclination conditions during use.

[0028] The beneficial effects of this utility model are:

[0029] 1. The scanning device for the deep foundation pit, when it is necessary to scan the deep foundation pit, first places the whole device on the top of the deep foundation pit. When the whole device is not in a horizontal state, the set power component can drive the sliding plate to slide. The sliding plate drives the fixed plate to rotate upward or downward through two guide columns and two guide grooves to ensure that the whole device is in a horizontal state and that the 3D laser scanner can be vertically extended into the deep foundation pit when in use.

[0030] 2. The deep foundation pit scanning device, through a set drive component, can drive a sliding column to slide downwards. The sliding column slides on a first fixed column to ensure the stability of the sliding. The sliding column drives the protective cover and the 3D laser scanner to move downwards. The 3D laser scanner emits a laser beam and receives reflected signals to quickly acquire high-precision 3D point cloud data of the foundation pit surface and generate an overall 3D model of the foundation pit. The set protective cover ensures that no soil will fall on the 3D laser scanner during operation, ensuring the stability of the 3D laser scanner during use. Attached Figure Description

The 3D laser scanner 5 is fixedly installed at the bottom of the sliding column 3. The 3D laser scanner 5 is covered with a protective cover 4, and the protective cover 4 is fixedly connected to the sliding column 3.

[0044] The drive assembly is located inside the fixed plate 1 and is used to drive the sliding column 3 to slide.

[0045] The base 6 is rotatably mounted on the bottom of the fixed plate 1. A power cavity 7 is provided inside the base 6. A sliding plate 8 is slidably installed inside the power cavity 7. A limit groove 9 is provided at the bottom of the fixed plate 1. The upper end of the sliding plate 8 passes through the power cavity 7 and extends into the limit groove 9. Guide grooves 10 are provided in the limit groove 9 on both sides of the sliding plate 8. Guide posts 11 fixed to the sliding plate 8 are slidably installed in both guide grooves 10.

[0046] The power unit is located inside the base 6 and is used to drive the sliding plate 8 to slide.

[0047] When scanning a deep foundation pit, the entire device is first placed on top of the deep foundation pit. When the entire device is not in a horizontal state, the sliding plate 8 can be driven to slide through the set power component. The sliding plate 8 drives the fixed plate 1 to rotate upward or downward through two guide columns 11 and two guide grooves 10 to ensure that the entire device is in a horizontal state and that the three-dimensional laser scanner 5 can be vertically extended into the deep foundation pit when in use.

[0048] The sliding column 3 can be driven to slide downwards by the set driving components. The sliding column 3 slides on the first fixed column 14 to ensure the stability of the sliding. The sliding column 3 drives the protective cover 4 and the 3D laser scanner 5 to move downwards. The 3D laser scanner 5 quickly acquires high-precision 3D point cloud data of the foundation pit surface by emitting laser beams and receiving reflected signals, and generates an overall 3D model of the foundation pit. The set protective cover 4 ensures that no soil will fall on the 3D laser scanner 5 during operation, ensuring the stability of the 3D laser scanner 5 during use.

[0049] In this embodiment, the driving component includes:

[0050] The first threaded rod 12 is rotatably installed in the sliding groove 2 and located at the top of the sliding column 3. The lower end of the first threaded rod 12 passes through the sliding column 3 and is threadedly connected to the sliding column 3. The upper end of the first threaded rod 12 passes through the sliding groove 2 and extends to the outside. The top end of the first threaded rod 12 is fixedly installed with a first operating disc 13.

[0051] The first operating disk 13 is rotated, which drives the first threaded rod 12 to rotate. Under the action of the thread, the sliding column 3 slides downward.

One end of the worm 17 passes through the power cavity 7 and extends to the outside. A second operating disc 18 is fixedly installed at one end of the worm 17. Both the second threaded rod 16 and the worm 17 are rotatably connected to the power cavity 7.

[0054] When scanning a deep foundation pit, the entire device is first placed on top of the pit. Then, it is checked whether the device is level. If the device is not level, the second operating disc 18 is rotated, which drives the worm gear 17 to rotate. The worm gear 17 drives the worm wheel 15, which meshes with it, to rotate. The worm wheel 15 drives the second threaded rod 16 to rotate. Under the action of the thread, the sliding plate 8 slides. The sliding plate 8 drives the fixed plate 1 to rotate upward or downward through the two guide posts 11 and the two guide grooves 10. When the device is level, the second operating disc 18 is stopped to ensure that the 3D laser scanner 5 can be vertically inserted into the deep foundation pit during use.

The worm gear 17 rotates the worm wheel 15 that meshes with it. The worm wheel 15 rotates the second threaded rod 16. Under the action of the thread, the sliding plate 8 slides on the two third fixed columns 20. The sliding plate 8 rotates the fixed plate 1 upward or downward through the two guide columns 11 and the two guide grooves 10. Observe the level bubble 21 at the same time. When the device is level, stop rotating the second operating disk 18 to ensure that the 3D laser scanner 5 can be vertically inserted into the deep foundation pit during use.

[0072] Rotating the first operating disk 13 drives the first threaded rod 12 to rotate. Under the action of the thread, the sliding column 3 slides downward. The sliding column 3 slides on the first fixed column 14 to ensure the stability of the sliding. The sliding column 3 drives the protective cover 4 and the 3D laser scanner 5 to move downward. The 3D laser scanner 5 quickly acquires high-precision 3D point cloud data of the foundation pit surface by emitting laser beams and receiving reflected signals, and generates an overall 3D model of the foundation pit. The protective cover 4 ensures that no soil will fall on the 3D laser scanner 5 during operation, thus ensuring the stability of the 3D laser scanner 5 during use.
