Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial heritage renovation technology, specifically to a BIM-based intelligent renovation construction system for industrial heritage. Background Technology
[0002] With the continuous development of technology, the constant updating of BIM technology, and the evolution of heritage protection concepts, BIM can not only be applied in modern architectural design but also extended to the field of architectural heritage protection, realizing the digitalization and scientification of heritage protection. The protection and utilization of modern and contemporary architectural heritage through BIM is equally important, involving a vast array of objects and diverse needs. However, it has long relied on experience and intuition, lacking scientific decision-making methods and quantitative technology platforms. There is an urgent need to explore new technologies and platforms. Compared to the construction industry, current research on the entire process and life cycle of architectural heritage protection is significantly insufficient, and protection and utilization are often separated. The protection of modern and contemporary architectural heritage lacks information-based and digital methods and platforms for operation, and related BIM technologies and theories are lacking and unsystematic.
[0003] Among them, announcement number CN115689373A disclosed a method for the protection and utilization of modern and contemporary architectural heritage based on MHBIM. This method involves acquiring heritage data from 3D laser point clouds and mapping the acquired data; using BIM technology to model the point cloud model; integrating and managing data information from the entire process of heritage protection and utilization to generate a multi-source data fusion platform; classifying modern and contemporary architectural heritage components into family libraries and establishing coding standards; evaluating the entire process of heritage protection and utilization; constructing a full life-cycle information record archive for heritage; developing a plugin that can automatically extract key information from the BIM model for physical environment simulation; and modifying the architectural heritage buildings based on their authenticity and protection and restoration plans. Through physical environment simulation, a physical scale model is created and modified, and combined with the BIM model, a physical model is automatically created using 3D printing technology. However, this technical solution still has shortcomings:
[0004] Existing 3D printers have a certain height and only a single workstation. Therefore, after each printing is completed, the physical object needs to be manually lifted down from the high worktable, which is not only labor-intensive but also wastes time and reduces the efficiency of intelligent transformation of industrial heritage.

It solves the problem that existing 3D printers have a certain height and only a single workstation, so after each printing, the physical object needs to be manually lifted down from the high worktable, which is not only labor-intensive but also wastes time and reduces the efficiency of intelligent renovation and construction of industrial heritage.

[0018] (III) Beneficial Effects
[0019] Compared with existing technologies, this invention provides a BIM-based intelligent renovation construction system for industrial heritage, which has the following beneficial effects:
[0020] 1. This intelligent renovation and construction system for industrial heritage using BIM technology uses a second motor to drive a transmission rod to rotate. The transmission rod, through the first and second bevel gears, drives the rotating tube to rotate. The rotating tube then drives the worktables on both sides to rotate, which allows the printed building entity to be rotated to the outside of the U-shaped frame for unloading. This does not affect the normal operation of the 3D printer, reduces the time wasted on material changes, and improves work efficiency.
[0021] 2. This intelligent industrial heritage renovation construction system utilizing BIM technology rotates two worktables via a rotating tube, causing two fixed spur gears to rotate. This rotation of the spur gears drives the worm gear, which in turn drives the worm wheel. This, in turn, causes the two push rods below the 3D printer to rotate vertically, pushing the worktable to a higher position for easy printing of the building. Simultaneously, the two push rods on the other side rotate horizontally, lowering the worktable to a lower position for convenient and time-saving unloading of the printed building.
[0022] 3. This intelligent transformation and construction system for industrial heritage using BIM technology uses a first motor to drive a turntable to rotate, which causes the pin to rotate around the rotating rod as an axis. This causes the pin to push the movable ring to move, which in turn causes the adjusting rod to move the mounting plate. This allows for the adjustment of the 3D printer's height, making it convenient to adjust the height of the 3D printer according to the height of the printed building entity. This saves printing time and improves printing efficiency. Attached Figure Description

A retaining ring is fixedly sleeved on the front end of the round pin 8 to prevent the round pin 8 from slipping out of the movable ring as much as possible.
[0034] Example 3
[0035] Please see Figure 1-5 The bottom inner wall of the U-shaped frame 1 is provided with a first transmission mechanism that drives the two second shaft pins 25 to rotate. The first transmission mechanism includes spur gears 30 and crown tooth rings 15. The front end of the first shaft pin 24 is fixedly sleeved with a worm gear 31.

[0036] Example 4
[0037] Please see Figure 1-5 A second transmission mechanism for rotating the rotating tube 13 is provided on the inner wall of one side of the upper end of the U-shaped frame 1. The second transmission mechanism includes a first bevel gear 21 and a second bevel gear 20. The first bevel gear 21 is fixedly sleeved on the upper end of the rotating tube 13. A support plate 18 is fixedly provided on the inner wall of one side of the upper end of the U-shaped frame 1. A transmission rod 19 is rotatably provided on the side of the support plate 18 near the rotating tube 13. The second bevel gear 20 is fixedly sleeved on the end of the transmission rod 19 near the first bevel gear 21. The first bevel gear 21 and the second bevel gear 20 are meshed and connected. A second motor 29 is fixedly provided on the side of the support plate 18 away from the transmission rod 19. The output end of the second motor 29 is fixedly connected to one end of the transmission rod 19. The second motor 29 is fixedly connected to the support plate 18 through a second support frame, making the connection between the second motor 29 and the support plate 18 more stable. The second motor 29 is a geared motor, which can provide a large and stable transmission force.
[0038] In summary, this intelligent industrial heritage renovation construction system utilizing BIM technology, during operation, uses a first motor 17 to drive a turntable 7 to rotate, causing a pin 8 to rotate around a rotating rod 6. This pin 8 pushes a movable ring 9 to move, which in turn causes an adjusting rod 2 to move a mounting plate 3, thus allowing for height adjustment of the 3D printer 4. This facilitates adjusting the height of the 3D printer 4 according to the height of the printed building entity, saving printing time and improving printing efficiency. After printing is complete, a second motor 29 drives a transmission rod 19 to rotate. The transmission rod 19, via a first bevel gear 21 and a second bevel gear 20, drives a rotating tube 13 to rotate. The rotating tube 13 then drives the two side worktables 16 to rotate, thus rotating the printed building entity to... Unloading is performed on the outside of the U-shaped frame 1 without affecting the normal operation of the 3D printer 4, reducing the time wasted on material changes and improving work efficiency. While the rotating tube 13 drives the two worktables 16 to rotate, it also causes the crown gear ring 15, which is fixedly set on the two spur gears 30, to rotate. This causes the spur gears 30 to rotate, driving the worm gear 28 to rotate. The worm gear 28 drives the worm wheel 31 to rotate, which in turn drives the two push rods 26 that are rotated to the bottom of the 3D printer 4 to rotate towards the vertical, thus pushing the worktable 16 to a higher position for easy printing of building objects. At the same time, the two push rods 26 on the other side rotate towards the horizontal, thus lowering the worktable 16 to a lower position for easy and time-saving unloading of the printed building objects.
