Description

Technical Field

[0001] This utility model relates to a BIM-based building model building device. Background Technology

[0002] In engineering design, not only are flexible and adaptable block sizes required, but also convenient block fabrication and rapid hoisting during construction. This necessitates a limited number of block types and specifications, while allowing for different combinations on the building's facade and plan surfaces to ensure the walls meet usage requirements. However, traditional block masonry methods waste significant manpower and time, a problem that needs to be addressed.

[0003] Chinese utility model patent published on October 30, 2018, with publication number "CN208023979U", discloses "an automatic construction device for cement mortar masonry based on BIM building model, including a main body, a terminal block and an information port fixedly connected to the side wall of the main body, a first rotating disk fixedly connected to the base surface of the main body, a rotating arm connected to the first rotating disk, a second movable shaft connected to the end of the rotating arm away from the first rotating disk, a drive arm fixedly connected to the second movable shaft, a first movable shaft connected to the end of the drive arm away from the second movable shaft, a working arm fixedly connected to the first movable shaft, and a working second rotating disk connected to the end of the working arm away from the first movable shaft."

[0004] While this application addresses some of the problems in the background technology, the high position of the block box in the device makes it inconvenient to stack bricks. Furthermore, as the bricks are gradually consumed during use, the height decreases, requiring the robotic arm on one side of the device to be constantly raised and lowered, which affects work efficiency.

[0005] Chinese utility model patent CN209704049U, published on November 29, 2019, discloses "a BIM-based building model building device". It includes a main body and a mobile vehicle. A robotic arm is installed on the main body. A control system is connected to one side of the main body. A drive wheel is connected to the lower surface of the main body. The drive wheel is movably connected to a slide rail. A low platform is fixedly connected to one end of the main body. Hydraulic lifting columns are symmetrically installed on the upper surface of the low platform. A support plate is fixedly connected to the upper end of the hydraulic lifting columns.

[0006] When building architectural models, robotic arms are used to grip bricks. After the robotic arm has gripped the upper half of the bricks, gripping the lower half becomes much more difficult. In addition, the existing devices are not easy to move and have poor flexibility, so further improvements are needed. Summary of the Invention

[0007] The technical problem to be solved by this utility model is how to overcome the above-mentioned defects of the prior art and provide a BIM-based building model building device.

[0008] To solve the above-mentioned technical problems, this utility model provides a BIM-based building model building device, comprising a main body and a mobile vehicle. The main body is equipped with a robotic arm, which has a robotic hand for grasping blocks. The mobile vehicle includes a frame and a block box mounted on the frame, with four wheels below the frame. The frame is hollow, and the block box includes a box frame and a movable base plate. The box frame is fixed to the frame, and the movable base plate is located inside the box frame. An unloading station is located next to the robotic arm, with a pit in the center of the unloading station. A vertical hydraulic cylinder is fixed in the pit. Each wheel has a track wheel on its outer side. Two parallel guide rails are provided on both sides of the unloading station, and guide rails are connected to the front ends of both parallel guide rails. The distance between the two sides of the mobile vehicle and the track wheels is equal to the distance between the two parallel guide rails.

[0009] Before use, the user fills the block box with blocks, then pushes the trolley between the front ends of the two guide rails, and then pushes the trolley onto the guide rails, as shown. Figure 3 As shown. Continue along the guide rail, push the trolley onto the parallel guide rail, and position the trolley above the pit, as shown. Figure 4 As shown, the robotic arm and robotic hand can then be activated to grab the upper layer of blocks in the block box.

[0010] After the blocks at the top of the block box are removed, pause the robotic arm and manipulator. Then, manually or automatically activate the vertical hydraulic cylinder to extend its piston rod, which then rests against the center of the movable base plate. Continue extending the cylinder to lift the movable base plate and the remaining blocks to a suitable height. Figure 5 As shown, the robotic arm continues to grab the remaining blocks.

[0011] With this design, the blocks are not easily detached during the transportation of blocks by the mobile cart, as they are blocked by the box frame; the lower layer of blocks inside the block box can be easily lifted to an appropriate height for the robotic arm or hand to grasp, which is simple and convenient.

[0012] As an optimization, guide posts are provided at the four corners of the movable base plate. This design prevents the movable base plate from easily tipping over when the vertical hydraulic cylinder lifts it.

[0013] As an optimization, each track wheel includes a cylindrical wheel body and a disc disposed inside the cylindrical wheel. The radius of the disc is larger than the radius of the cylindrical wheel body, and the sum of the radius of the cylindrical wheel body and the height of the parallel guide rail is greater than the radius of the wheel. With this design, the mobile vehicle can travel on flat ground with ease and stability thanks to its large-diameter wheels; when the mobile vehicle is pushed onto the parallel track and stops above the pit, it is stable and secure.

[0014] This utility model has a simple structure, is easy to use, and is suitable for BIM-based building construction. Attached Figure Description
