Based on the embodiments in the present application, any other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0048] The embodiments of the present application provide an intelligent construction point cloud acquisition device fused and registered with a BIM model. The intelligent construction point cloud acquisition device fuses and registers with the BIM model, and uses the positioning of the vehicle body and the movement of the vehicle body to sequentially arrange marker columns at different construction points, so as to realize automatic and high-precision marking of the construction points. The present application solves the technical problem that the related art has low efficiency and poor precision in manually acquiring the construction points, and is difficult to adapt to the intelligent construction demand.

[0049] Reference Figure 1 and Figure 2 An intelligent construction point cloud acquisition device fused and registered with a BIM model, comprising a vehicle body 1, a positioning member 2, and an acquisition assembly. The vehicle body 1 is determined by the positioning member 2 to have a real-time position, and is moved to a specified construction point by the acquisition assembly according to the BIM model, and the acquisition assembly marks at the construction point.

[0050] Reference Figure 1 and Figure 2 The vehicle body 1 comprises a bearing table 11, and the bearing table 11 is moved by the vehicle body 1.

[0051] The positioning member 2 comprises a tracking positioner, which sends the real-time position of the vehicle body 1 by emitting a signal. The real-time position of the vehicle body 1 and the movement track of the vehicle body 1 can be obtained by using the positioning member 2, so as to ensure that the vehicle body 1 moves to the specified position.

[0052] Reference Figure 1 and Figure 2Wherein, the collecting assembly comprises a conveying groove 3, a pushing assembly 4, a pressing assembly 5 and a plurality of marking columns 6.

[0053] With reference to Figure 1 and Figure 2 , specifically, the conveying groove 3 is installed on the side surface of the bearing table 11, and one end of the conveying groove 3 is provided with an opening, and the top surface of the conveying groove 3 is open, and the plurality of marking columns 6 are arranged in sequence and placed in the conveying groove 3. The pushing assembly 4 is used to move the marking columns 6 in the conveying groove 3 towards the outlet of the conveying groove 3, and the marking columns 6 are sequentially pushed out of the outlet of the conveying groove 3.

[0054] With reference to Figure 1 and Figure 2 , the pressing assembly 5 is installed on the bearing table 11, and the driving end of the pressing assembly 5 is located at the outlet of the conveying groove 3, and is used to press the marking columns 6 pushed out of the conveying groove 3, so as to insert the marking columns 6 into the construction point, and fix the marking columns 6.

[0055] After the vehicle body 1 moves to the construction point, the pushing assembly 4 pushes the marking columns 6 out of the conveying groove 3 and places them at the construction point, and then the pressing assembly 5 inserts the marking columns 6 at the construction point, so as to complete the marking collection of the construction point.

[0056] With reference to Figures 3-5 , specifically, the conveying groove 3 comprises a first section and a second section, the first section is installed on the side surface of the bearing table 11, and the second section of the conveying groove 3 is installed on the rear end surface of the bearing table 11, the first section and the second section are communicated, and one end of the second section away from the first section is the outlet of the conveying groove 3.

[0057] In this way, on the one hand, the length of the conveying groove 3 is lengthened to accommodate more marking columns 6. On the other hand, the opening of the conveying groove 3 is arranged on the rear end surface of the bearing table 11, and after the marking columns 6 are fixed at the construction point, it does not affect the forward movement of the vehicle body 1.

[0058] With reference to Figures 3-5 , wherein the intelligent construction point cloud collecting device fused with the BIM model registration further comprises a limiting assembly 7, the limiting assembly 7 comprises a limiting frame 71 and a limiting elastic member 72, the limiting frame 71 limits the marking columns 6 from sliding out of the outlet of the conveying groove 3 at will, and limits the marking columns 6 from being pushed out of the conveying groove 3 and being skewed.

[0059] With reference to Figures 3-5Specifically, the limiting frame 71 comprises a limiting plate 711 and a sliding bar 712, the limiting plate 711 and the sliding bar 712 are connected, the sliding bar 712 is slidingly arranged at the side of the conveying groove 3, and the limiting plate 711 is located at the outlet of the conveying groove 3. The limiting plate 711 can block the outlet of the conveying groove 3 by moving the sliding bar 712 close to or away from the outlet of the conveying groove 3, so as to limit the marker column 6 from sliding out of the outlet of the conveying groove 3 at will.

[0060] With reference to Figures 3-5 The two ends of the limiting elastic member 72 are connected with the sliding bar 712 and the groove wall of the conveying groove 3 respectively. By the elastic force of the limiting elastic member 72, the limiting plate 711 is abutted against the end portion at the outlet of the conveying groove 3. When the marker column 6 is pushed out of the outlet of the conveying groove 3, the marker column 6 pushes the limiting plate 711 to move, and at this time, the limiting elastic member 72 is deformed to open the outlet of the conveying groove 3. In the embodiment, the limiting elastic member 72 comprises a spring.

[0061] In this way, when the marker column 6 moves with the vehicle body 1, the limiting plate 711 is abutted against the end portion at the outlet of the conveying groove 3 under the elastic force of the limiting elastic member 72, so as to block the outlet of the conveying groove 3 and limit the marker column 6 from sliding. When the vehicle body 1 is located at the construction point, the pushing assembly 4 pushes the marker column 6 to move towards the outlet of the conveying groove 3, and the marker column 6 pushes the limiting plate 711 away from the opening of the conveying groove 3. At this time, the opening of the conveying groove 3 is gradually opened, and the marker column 6 gradually leaves the conveying groove 3. The marker column 6 is clamped by the next marker column 6 and the limiting plate 711, so as to limit the marker column 6 from being skewed, and the compacting assembly 5 can vertically insert the marker column 6 at the construction point. In addition, the marker column 6 in the conveying groove 3 is clamped by the pushing end of the pushing assembly 4 and the limiting plate 711, so as to be not easily shaken at will.

[0062] With reference to Figures 3-5 The pushing end of the pushing assembly 4 moves along the extension direction of the conveying groove 3 to push the marker column 6 towards the outlet of the conveying groove 3. Specifically, the pushing assembly 4 comprises a conveying belt mechanism 41 and a pushing plate 42.

[0063] With reference to Figures 3-5 The inside of the bearing table 11 is provided with a mounting space, and the conveying mechanism is mounted in the inside of the bearing table 11. The pushing plate 42 is mounted at the conveying end of the conveying belt mechanism 41, one side groove wall of the conveying groove 3 is provided with a sliding groove 3a along the extension direction of the conveying groove 3, the pushing plate 42 extends into the conveying groove 3 through the sliding groove 3a, and the pushing plate 42 moves to push the marker column 6 to convey.

[0064] In this way, the pushing plate 42 is driven by the conveying belt mechanism 41 to move, so as to push the marker column 6 to convey. The conveying direction of the conveying belt mechanism 41 can be arranged according to the extension direction of the conveying groove 3, so as to adapt to push the marker column 6 to convey in various directions.

[0065] Referring to Figures 1-3 The pressing assembly 5 comprises a pressing driving member 52 and a pressing plate 51. The pressing driving member 52 is installed on the bearing table 11. The pressing plate 51 is connected with the pushing end of the pressing driving member 52, so that the pressing plate 51 is driven by the pressing driving member 52 to ascend and descend, and the pressing plate 51 is pressed downward to press the marker column 6 downward. In the embodiment, the pressing driving member 52 comprises a pneumatic cylinder.

[0066] In this way, when the marker column 6 is pushed out of the conveying groove 3 and clamped between the limiting plate 711 and the next marker column 6, the marker column 6 is located below the pressing plate 51, and the pressing plate 51 is lowered to insert the marker column 6 into the construction point, thereby realizing the marking and collecting of the construction point.

[0067] In the embodiment, the bottom end of the marker column 6 is in a conical shape, so as to be conveniently inserted into the construction point.

[0068] Referring to Figure 1 Optionally, the intelligent construction point cloud collecting device integrated with the BIM model further comprises a distance measuring instrument 8 installed on the bearing table 11, and the distance measuring instrument 8 is used to detect the distance between the vehicle body 1 and the installed marker column 6.

[0069] In this way, after the vehicle body 1 moves to the next construction point, the distance between the current position and the marker column 6 at the previous construction point is measured by the distance measuring instrument 8, so as to check whether the distance between the two construction points meets the requirements in the BIM model, thereby improving the construction accuracy.

[0070] Referring to Figures 6-8 The marker column 6 comprises a sleeve 61, an extension rod 62, an extension elastic member 63 and a limiting structure 64. In the embodiment, the top end of the sleeve 61 is open, and the bottom end of the sleeve 61 is in a conical shape. The extension rod 62 is arranged in the sleeve 61, and the extension rod 62 is slidable up and down relative to the sleeve 61, so as to adjust the length of the entire marker column 6.

[0071] Referring to Figures 6-8 The extension elastic member 63 is connected with the inner bottom surface of the sleeve 61 and the bottom end surface of the extension rod 62 at two ends, respectively. The elastic force of the extension elastic member 63 makes the extension rod 62 slide upward to increase the length of the extension rod 62 extending out of the sleeve 61, so as to change the length of the marker column 6. It can be understood that the extension rod 62 is at the lowest point, and the extension elastic member 63 is in a deformed state. In the embodiment, the extension elastic member 63 comprises a spring.

[0072] The limiting structure 64 is used to limit the extension rod 62 from extending out of the sleeve 61, i.e., the limiting assembly 7 makes the extension elastic member 63 in a deformed state. The extension rod 62 is pressed downward by the pressing assembly 5, so as to release the limitation on the upward sliding of the extension rod 62.

[0073] Referring to Figures 6-9Specifically, the limiting structure 64 comprises a limiting block 64a, a guide groove 64b and a limiting groove 64c.

[0074] Referring to Figures 6-9 The limiting block 64a is fixed on the circumferential side of the telescopic rod 62. The guide groove 64b is arranged on the inner side of the sleeve body 61, and the length direction of the guide groove 64b is arranged along the length direction of the sleeve body 61. The limiting block 64a is adapted to slide in the guide groove 64b. The limiting groove 64c is arranged on the inner side of the sleeve body 61, and the length direction of the limiting groove 64c is arranged along the circumferential direction of the sleeve body 61.

The upper groove wall of the limiting groove 64c is a limiting surface 64ca, and the lower groove wall of the limiting groove 64c is a guide surface 64cb, which is arranged obliquely.

[0075] Referring to Figures 6-9 The limiting block 64a is abutted against the limiting surface 64ca under the action of the telescopic elastic member 63, so as to limit the upward sliding of the telescopic rod 62, thereby facilitating the conveying of the marker column 6. When the pressing assembly 5 presses the marker column 6, the telescopic rod 62 slides downward relative to the sleeve body 61, and at this time, the limiting block 64a slides downward along the guide surface 64cb and into the guide groove 64b. After the pressing assembly 5 inserts the marker column 6 into the construction point, the pressing plate 51 of the pressing assembly 5 slides upward, and at this time, under the action of the telescopic elastic member 63, the limiting block 64a slides upward in the guide groove 64b, and the telescopic rod 62 slides upward relative to the sleeve body 61, so as to increase the length of the marker column 6.

[0076] In this way, by increasing the length of the marker column 6, it is more convenient to identify the position of the marker column 6, and it is also convenient for the range finder 8 to align the marker column 6.

[0077] Referring to Figure 6 and Figure 7 Optionally, the marker rod comprises a positioning module 65. In this embodiment, the positioning module 65 is installed on the telescopic rod 62.
