Abstract
Description
Technical Field
[0001] This utility model relates to the field of architectural engineering design technology, and more specifically, to a BIM building model for architectural engineering design. Background Technology
[0002] BIM, or Building Information Modeling, is a complete information model that integrates engineering information, processes, and resources at different stages throughout the entire lifecycle of a project into a single model, making it convenient for all project stakeholders to use. By simulating the real information of a building through 3D digital technology, BIM provides a coordinated and internally consistent information model for engineering design and construction. BIM achieves the integration of design and construction, enabling collaboration among various disciplines, thereby reducing engineering production costs, effectively improving collaborative efficiency, and ensuring accountability.
[0003] BIM building models are large and heavy. Existing BIM building models can be moved by detachable casters on their bottom surfaces. However, when the BIM building model needs to be parked in a fixed area, the casters cause instability and easy movement. The casters need to be removed to make the BIM building model stable, which is very inconvenient. BIM building models without casters on their bottom surfaces need to be loaded onto a forklift before they can be moved by the forklift. However, in some spaces with limited space, it is not possible to use a forklift to move them effectively, which cannot meet the needs of movement and is very inconvenient. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, a BIM building model for architectural engineering design is provided.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a BIM building model for architectural engineering design, including a base, on which the building model body is set, and movable seats are set on both the left and right sides of the base. At least three universal wheels are set on the bottom surface of the movable seats. The movable seats are provided with vertically extending grooves on the surface opposite to the base. An insertion rod is slidably arranged in the grooves. A driving mechanism for driving the insertion rod to move up and down is provided on the movable seats. A slot for inserting the insertion rod is provided on the side wall of the base. A limiting post is provided on the upper side wall of the slot. The length of the limiting post plus the thickness of the insertion rod is not greater than the vertical height of the slot. A limiting hole is provided on the insertion rod for the limiting post to be inserted.
[0006] Preferably, each of the movable seats is provided with two sliding grooves, and an insertion rod is slidably arranged in each sliding groove. The driving mechanism drives the two insertion rods to move up and down synchronously. Two slots are provided on the left and right sides of the base respectively.
[0007] Preferably, the drive mechanism includes a dual-axis motor and two lead screws. The two lead screws are rotatably disposed in two sliding grooves and extend vertically. The two insertion rods are threadedly connected to the two lead screws. The movable seat has a mounting cavity located between the two lead screws. The dual-axis motor is installed in the mounting cavity. Each of the two output shafts of the dual-axis motor is provided with a first bevel gear, and each of the two lead screws is provided with a second bevel gear. The two second bevel gears mesh with the two first bevel gears.
[0008] Preferably, the two slides are spaced apart in the front-to-back direction, and the two slides are symmetrical about the center of the movable seat.
[0009] Preferably, the height of the slot in the vertical direction is not less than twice the thickness of the insertion rod, and the length of the limiting post is not less than the thickness of the insertion rod.
[0010] Preferably, a guide post is provided on the bottom surface of the limiting post. Both the limiting post and the guide post are cylindrical structures. The limiting post and the guide post are coaxially arranged. The diameter of the guide post is smaller than the diameter of the limiting post. The insertion rod is provided with a strip-shaped notch for the guide post to slide into the limiting hole. The width of the strip-shaped notch is equal to the diameter of the guide post.
[0011] Preferably, the movable seat has a cuboid structure and four casters are provided, which are respectively located at the four corners of the bottom surface of the movable seat.
[0012] Preferably, the movable base is provided with a battery to provide power to the drive mechanism.
[0013] The beneficial effects of this utility model are as follows: Two movable seats are correspondingly set on both sides of the base. At this time, the insertion rod is inserted into the corresponding slot, and the drive mechanism drives the insertion rod to rise. At this time, the limiting post is inserted into the corresponding limiting hole, and then the insertion rod drives the base to rise through the slot, so that the base leaves the ground. Then the building model body can be easily moved. The volume of the movable seats and drive mechanism is much smaller than that of a forklift, which can move the building model body in the case of limited space. At the same time, the base can be lifted off the ground by the drive mechanism and the insertion rod, so that the building model body can be moved. This is very convenient. After the building model body is moved to the position, the drive mechanism drives the insertion rod to move down, so that the base returns to the ground. After removing the movable seats, the volume of the BIM building model is reduced, and at this time the BIM building model is fixed and stable and will not move. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. In addition, the directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. The directional terms are used to better and more clearly explain and understand this utility model, and are not intended to indicate or imply the necessary orientation of this utility model. Therefore, they should not be construed as limitations on this utility model.
[0020] Examples of embodiments of this utility model Figures 1 to 4As shown, a BIM building model for architectural engineering design includes a base 1, on which a building model body 2 is mounted. The building model body 2 is located on the top surface of the base 1. Preferably, the base 1 and the building model body 2 are integrally formed. Movable seats 3 are provided on both the left and right sides of the base 1. At least three casters 6 are provided on the bottom surface of the movable seats 3. When three casters are provided, the three casters 6 are arranged in an equilateral triangle on the bottom surface of the movable seats 3. Preferably, the movable seats 3 are cuboid structures, and four casters 6 are provided, with the four casters 6 corresponding to the four corners of the bottom surface of the movable seats 3. This allows... The movable base 3 and the BIM building model are more stable when moving. The movable base 3 has a vertically extending groove 30 on the surface opposite to the base 1. An insertion rod 4 is slidably installed in the groove 30. The movable base 3 is equipped with a drive mechanism to drive the insertion rod 4 to move up and down. The side wall of the base 1 is equipped with a slot 10 for inserting the insertion rod 4. The upper side wall of the slot 10 is equipped with a limiting post 5. The length of the limiting post 5 plus the thickness of the insertion rod 4 is not greater than the vertical height of the slot 10. The insertion rod 4 is equipped with a limiting hole 40 for the limiting post 5 to be inserted into, that is, the limiting hole 40 is located on the top surface of the insertion rod 4.
[0021] Two movable seats 3 are positioned on either side of the base 1. The insertion rod 4 is then inserted into the corresponding slot 10. The drive mechanism drives the insertion rod 4 upwards, at which point the limiting post 5 is inserted into the corresponding limiting hole 40. The limiting post 5 and the limiting hole 40 prevent the movable seat 3 from detaching from the base 1 when the BIM building model moves. The insertion rod 4 then drives the base 1 upwards through the slot 10, causing the base 1 to leave the ground. The building model body 2 can then be easily moved. The volume of the movable seat 3 and the drive mechanism is much smaller than that of a forklift, allowing the building model body 2 to be moved even in limited space. Simultaneously, the drive mechanism and the insertion rod 4 allow the base 1 to leave the ground, making the building model body 2 very convenient to move. After the building model body 2 is moved to its position, the drive mechanism drives the insertion rod 4 downwards, allowing the base 1 to return to the ground. Removing the movable seat 3 reduces the volume of the BIM building model, and the BIM building model is now fixed and stable and will not move.
[0022] Further improvements, such as Figure 1 , Figure 2 and Figure 3As shown, each of the movable seats 3 is provided with two sliding grooves 30, and an insertion rod 4 is slidably disposed in each sliding groove 30. The driving mechanism drives the two insertion rods 4 to move up and down synchronously. Two slots 10 are provided on the left and right sides of the base 1. The driving mechanism includes a dual-axis motor 7 and two lead screws 70. The two lead screws 70 are rotatably disposed in the two sliding grooves 30, extending vertically. The two insertion rods 4 are threadedly connected to the two lead screws 70. The front and rear side walls of the insertion rods 4 abut against the front and rear inner side walls of the sliding grooves 30, thereby preventing the insertion rods 4 from rotating with the lead screws 70. The movable seat 3 is provided with a mounting cavity 31 located between the two lead screws 70. The mounting cavity 31 is located near the top of the movable seat 3. The front and rear ends of the mounting cavity 31 are connected to the two sliding grooves 30. The dual-axis motor 7 is installed in the mounting cavity 31 and is set on the inner bottom surface of the mounting cavity 31. The two output shafts of the dual-axis motor 7 extend in the front-rear direction. Each of the two output shafts of the dual-axis motor 7 is provided with a first bevel gear 71, and each of the two lead screws 70 is provided with a second bevel gear 72. The two second bevel gears 72 mesh with the two first bevel gears 71. When the two output shafts of the dual-axis motor 7 rotate synchronously, the two lead screws 70 are driven to rotate synchronously in the same direction through the two first bevel gears 71 and the two second bevel gears 72, so that the two insertion rods 4 move up and down synchronously.
[0023] Further improvements, such as Figure 2 and Figure 3 As shown, the two slides 30 are spaced apart in the front-to-back direction, and the two slides 30 are symmetrical about the center of the movable seat 3.
[0024] Further improvements, such as Figure 2 and Figure 4 As shown, the height of the slot 10 in the vertical direction is not less than twice the thickness of the insertion rod 4, and the length of the limiting post 5 is not less than the thickness of the insertion rod 4. This ensures the contact area between the limiting post 5 and the limiting hole 40, which can better prevent the moving seat 3 from detaching from the base 1.
[0025] Further improvements, such as Figure 2 and Figure 4As shown, a guide post 8 is provided on the bottom surface of the limiting post 5. Both the limiting post 5 and the guide post 8 are cylindrical structures. The limiting post 5 and the guide post 8 are coaxially arranged. The diameter of the guide post 8 is smaller than the diameter of the limiting post 5. The insertion rod 4 is provided with a strip-shaped notch 41 for the guide post 8 to slide into the limiting hole 40. The strip-shaped notch 41 extends in the left and right direction. One end of the strip-shaped notch 41 is connected to the limiting hole 40. The end of the strip-shaped notch 41 away from the limiting hole 40 is an open structure. The width of the strip-shaped notch 41 is equal to the diameter of the guide post 8. The guide post 8 and the strip-shaped notch 41 guide the insertion rod 4 when it is inserted into the slot 10.
[0026] Further improvements, such as Figure 2 and Figure 3 As shown, the movable base 3 is equipped with a battery 9 that provides power to the drive mechanism, facilitating the drive mechanism to move the insertion rod 4.
[0027] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
