Description

Technical Field

[0001] This invention relates to a device for the restoration of ancient buildings, specifically to a device for automatically polishing wooden pillars in ancient buildings. Background Technology

[0002] Ancient building restoration is the process of protecting, repairing, and restoring ancient buildings. These buildings are typically constructed of wood, and wooden pillars are a crucial component of their structure. They are commonly used to support the roof and floors. Wooden pillars have a long history in ancient architecture and have played an important role in many cultures.

[0003] When repairing wooden pillars, the process typically involves scraping, sanding, and cleaning, followed by applying a mixture of hemp and ash (a traditional Chinese finishing technique). This hemp-ash method is used for the walls and floors of ancient buildings and traditional dwellings. It boasts excellent crack resistance, breathability, and environmental friendliness, and has been widely adopted in traditional architecture throughout China.

[0004] However, the repair of wooden pillars requires manual sanding, which is very physically demanding for the workers. Summary of the Invention

[0005] To address the problems existing in the above-mentioned technologies, the present invention provides an automated device for sanding wooden posts.

[0006] The present invention provides a device for the restoration of ancient buildings, comprising a moving structure, a lifting structure, and a grinding structure;

[0007] The lifting structure is located on the upper side of the movable structure, and the lifting structure has a lifting block that can be raised and lowered.

[0008] The grinding structure is connected to the lifting block. The grinding structure includes a driving component, an annular rotating part, and a grinding assembly. The driving component is used to drive the annular rotating part to rotate. The annular rotating part has a notch. The grinding assembly is located at the inner end of the annular rotating part. The grinding assembly includes a telescopic component and an arc plate. The telescopic component is used to drive the arc plate to move. The inner end of the arc plate is provided with sandpaper.

[0009] The aforementioned beneficial effects are as follows: by moving the structure, the wooden column enters the annular rotating part through the notch. Subsequently, the telescopic component moves the arc-shaped plate, causing the sandpaper at the inner end of the arc-shaped plate to contact the wooden column. At this time, the driving component drives the annular rotating part to rotate, which in turn drives the telescopic component, the arc-shaped plate, and the sandpaper to rotate. The rotating sandpaper polishes the circumferential direction of the wooden column, and the lifting blocks drive the polishing structure to rise or fall, thus completing the polishing process of the entire wooden column. In this way, the polishing of the wooden column is automated.

[0010] In a preferred embodiment, the movable structure includes a plate structure, wheels, and a handle. The wheels are respectively disposed at the four lower corners of the plate structure, and the handle is disposed at the rear end of the plate structure.

[0011] The lifting structure includes a vertical block, a lead screw, a slide bar, and a lifting block. The vertical block is located on the upper front side of the plate structure. The lead screw and slide bar are arranged parallel to each other in the groove at the front end of the vertical block. The lifting block is located on the lead screw and slide bar.

[0012] In a preferred embodiment, the driving component includes a housing, a driving gear, two sets of driven gears, and an annular gear. The front end of the housing has an inlet, and the rear end of the housing is connected to a lifting block. A guide groove is provided on the lower side inside the front end of the housing. The annular rotating part is rotatably disposed in the guide groove. An annular gear is provided at the rear end of the annular rotating part. The driven gears are respectively provided on both sides of the rear end inside the housing. The two sets of driven gears are respectively meshed with the annular gear. The driving gear is respectively meshed with the two sets of driven gears.

[0013] The telescopic component has two parts, both of which are telescopic cylinders. The rear ends of the two telescopic cylinders are respectively connected to the inner ends of the annular rotating part. The telescopic rods of the two telescopic cylinders are respectively connected to the arc-shaped plate. The inner ends of the two arc-shaped plates are provided with sandpaper.

[0014] In a preferred embodiment, fastening screws are provided at both the top and bottom positions on both sides of the arc-shaped plate;

[0015] It also includes a scraping assembly and a sweeping assembly, each with two sets. The two sets of scraping assemblies are respectively located at the lower end of the annular rotating part, and the two sets of scraping and sweeping assemblies are respectively located at the upper end of the annular rotating part. Each set of scraping assemblies includes a scraper and a cylinder. The telescopic column of the cylinder is connected to the scraper, and the end of the cylinder is located on the lower plate, which is connected to the lower end of the annular rotating part. Each set of sweeping assemblies includes a cylinder structure and a sweeping brush. The telescopic body of the cylinder structure is connected to the sweeping brush, and the end of the cylinder structure is located on the upper plate, which is connected to the upper end of the annular rotating part.

[0016] The working method of the ancient building restoration equipment provided by the present invention includes the following steps;

[0017] By moving the movable structure, the wooden column enters the annular rotating part through the notch. Then, the telescopic component moves the arc-shaped plate, causing the sandpaper at the inner end of the arc-shaped plate to contact the wooden column. Subsequently, the driving component drives the annular rotating part to rotate, which in turn drives the telescopic component and the arc-shaped plate to rotate. At this time, the sandpaper at the inner end of the arc-shaped plate rotates, sanding the circumferential direction of the wooden column. Then, the lifting block drives the sanding structure to rise or fall, thus sanding the entire wooden column and achieving automated sanding of the wooden column.

[0018] The working method of the ancient building restoration equipment provided by the present invention includes the following steps;

[0019] The structure is moved by pushing the handle manually, and the motor drives the lead screw to rotate, causing the lifting block to rise or fall along the slide bar. The lifting block then drives the grinding structure to rise or fall.

[0020] The working method of the ancient building restoration equipment provided by the present invention includes the following steps;

[0021] By moving the movable structure, the wooden column enters the annular rotating part through the inlet and notch. Then, the telescopic cylinder drives the arc plate to move, so that the sandpaper at the inner end of the arc plate comes into contact with the wooden column. At this time, the rotary motor drives the drive gear to rotate, and the drive gear drives the two sets of driven wheels to rotate. The driven wheels drive the annular rotating part to rotate through the annular teeth. The annular rotating part rotates in the guide groove, so that the annular rotating part forms a circular motion. The annular rotating part drives the telescopic cylinder, the arc plate and the sandpaper to rotate. The sandpaper polishes the wooden column in the radial direction. Then, the lifting block drives the shell to rise or fall, thus completing the polishing process of the entire wooden column.

[0022] The working method of the ancient building restoration equipment provided by the present invention includes the following steps;

[0023] The replacement of the sandpaper is facilitated by the fastening screws installed at the top and bottom positions on both sides of the curved plate. First, fold the top and bottom ends of the sandpaper and place them in contact with the top and bottom ends of the curved plate. Then, tighten the fastening screws downwards so that the bottom of the fastening screws presses the top and bottom ends of the sandpaper against the top and bottom ends of the curved plate. To disassemble, simply tighten the fastening screws.

[0024] Once the wooden post enters the annular rotating section, the telescopic cylinder moves the curved plate, causing the sandpaper at the inner end of the curved plate to contact the wooden post. Then, the cylinder and its structure extend simultaneously, causing the scraper and cleaning brush to contact the wooden post. As the annular rotating section rotates, it drives the curved plate, scraper, and cleaning brush to rotate as well. The scraper first scrapes away the peeling material from the wooden post, then the sandpaper at the inner end of the curved plate polishes the post. Finally, the cleaning brush cleans the polished post. This process further automates the handling of the wooden post. Attached Figure Description

[0031] First embodiment:

[0032] like Figures 1 to 3 As shown, the present invention provides a restoration device for ancient buildings, including a moving structure 10, a lifting structure 20 and a grinding structure 30;

[0033] The lifting structure 20 is disposed on the upper side of the movable structure 10, and the lifting structure 20 has a lifting block 21 that can be raised and lowered.

[0034] The sanding structure 30 is connected to the lifting block 21. The sanding structure 30 includes a driving member 310, an annular rotating part 320, and a sanding assembly 330. The driving member 310 is used to drive the annular rotating part 320 to rotate. The annular rotating part 320 has a notch 321. The sanding assembly 330 is disposed at the inner end of the annular rotating part 320. The sanding assembly 330 includes a telescopic member 340 and an arc plate 331. The telescopic member 340 is used to drive the arc plate 331 to move. The inner end of the arc plate 331 is provided with sandpaper.

[0035] By moving the moving structure 10, the wooden column 1 enters the annular rotating part 320 through the notch 321. Then, the telescopic member 340 drives the arc plate 331 to move, so that the sandpaper at the inner end of the arc plate 331 contacts the wooden column 1. Subsequently, the driving member 310 drives the annular rotating part 320 to rotate, and the annular rotating part 320 drives the telescopic member 340 and the arc plate 331 to rotate. At this time, the sandpaper at the inner end of the arc plate 331 rotates, and the wooden column 1 is sanded in the circumferential direction. Then, the lifting block 21 drives the sanding structure 30 to rise or fall, and the entire wooden column 1 is sanded, thus realizing the automated sanding process of the wooden column 1.

[0036] Second embodiment:

[0037] like Figure 3 As shown, the movable structure 10 includes a plate structure 11, movable wheels 12, and handle 13. The movable wheels 12 are respectively arranged at the four corners of the lower end of the plate structure 11, and the handle 13 is arranged on the rear end of the plate structure 11.

[0038] The lifting structure 20 includes a vertical block 22, a lead screw 23, a slide bar 24, and a lifting block 21. The vertical block 22 is disposed on the upper front end of the plate structure 11. The lead screw 23 and the slide bar 24 are disposed in parallel in the groove 25 at the front end of the vertical block 22. The lifting block 21 is disposed on the lead screw 23 and the slide bar 24.

[0039] The handle 13 is manually pushed to move the structure, and the motor drives the lead screw 23 to rotate, causing the lifting block 21 to rise or fall along the slide bar 24. The lifting block 21 then drives the grinding structure 30 to rise or fall.

[0040] Third embodiment:

[0041] like Figures 1 to 3As shown, the driving component 310 includes a housing 311, a driving gear 312, two sets of driven gear sets 313, and an annular gear 314. The front end of the housing 311 is provided with an inlet 315, and the rear end of the housing 311 is connected to the lifting block 21. The lower side of the front end of the housing 311 is provided with a guide groove 316. The annular rotating part 320 is rotatably disposed in the guide groove 316. The rear end of the annular rotating part 320 is provided with an annular gear 314. The driven gear sets 313 are respectively provided on both sides of the rear end of the housing 311. The two sets of driven gear sets 313 are respectively meshed with the annular gear 314. The driving gear 312 is respectively meshed with the two sets of driven gear sets 313.

[0042] There are two telescopic components 340, both of which are telescopic cylinders 341.

The telescopic rods of the two telescopic cylinders 341 are respectively connected to the arc plate 331. The inner ends of the two arc plates 331 are provided with sandpaper.

[0043] By moving the movable structure 10, the wooden column 1 enters the annular rotating part 320 through the inlet 315 and the notch 321. Then, the telescopic cylinder 341 drives the arc plate 331 to move, so that the sandpaper at the inner end of the arc plate 331 contacts the wooden column 1. At this time, the rotary motor drives the drive gear 312 to rotate, and the drive gear 312 drives the two sets of driven wheel sets 313 to rotate. The driven wheel sets 313 drive the annular rotating part 320 to rotate through the annular tooth part 314. The annular rotating part 320 rotates in the guide groove 316, so that the annular rotating part 320 forms a circular motion. The annular rotating part 320 drives the telescopic cylinder 341, the arc plate 331 and the sandpaper to rotate. The sandpaper polishes the wooden column 1 in the circumferential direction. Then, the lifting block 21 drives the housing 311 to rise or fall, so that the polishing process of the entire wooden column 1 can be completed.

[0044] Fourth embodiment:

[0045] like Figures 4 to 6 As shown, fastening screws 335 are provided at the upper and lower positions on both sides of the arc plate 331;

[0046] It also includes a scraping assembly 40 and a sweeping assembly 50. Two sets of each scraping assembly 40 and sweeping assembly 50 are provided. The two sets of scraping assemblies 40 are respectively located at the lower end of the annular rotating part 320, and the two sets of sweeping assemblies 50 are respectively located at the upper end of the annular rotating part 320. Each set of scraping assemblies 40 includes a scraper 41 and a cylinder 42. The telescopic column of the cylinder 42 is connected to the scraper 41, and the end of the cylinder 42 is located on the lower plate 43, which is connected to the lower end of the annular rotating part 320. Each set of sweeping assemblies 50 includes a cylinder structure 51 and a sweeping brush 52. The telescopic column of the cylinder structure 51 is connected to the sweeping brush 52, and the end of the cylinder structure 51 is located on the upper plate 53, which is connected to the upper end of the annular rotating part 320.

[0047] By setting fastening screws 335 at both the top and bottom positions on both sides of the arc plate 331, it is easy to replace the sandpaper. First, fold the top and bottom ends of the sandpaper and contact them with the top and bottom ends of the arc plate 331 respectively. Then, tighten the fastening screws 335 downwards, so that the bottom of the fastening screws 335 presses the top and bottom ends of the sandpaper against the top and bottom ends of the arc plate 331. When disassembling, simply loosen the fastening screws 335.

[0048] When the wooden column 1 enters the annular rotating part 320, the telescopic cylinder 341 drives the arc plate 331 to move, so that the sandpaper at the inner end of the arc plate 331 contacts the wooden column 1. Then, the cylinder 42 and the cylinder structure 51 extend simultaneously, so that the scraper 41 and the cleaning brush 52 contact the wooden column 1 respectively. When the annular rotating part 320 rotates, it drives the arc plate 331, the scraper 41 and the cleaning brush 52 to rotate respectively. The scraper 41 first scrapes off the peeling material on the wooden column 1. Then, the sandpaper at the inner end of the arc plate 331 polishes the wooden column 1 after the peeling is removed. Finally, the cleaning brush 52 cleans the polished wooden column 1. In this way, the automated processing of the wooden column can be further realized.

[0049] In a further preferred embodiment, an image acquisition device, such as a camera, is installed on the annular rotating part. Through lifting and circular motion, the image acquisition device scans the entire wooden column, and the image data is transmitted to a remote display for human observation. The location to be repaired on the wooden column is then determined, indicating a damaged or missing area resulting in a dent. After determining the location, the repair procedure is initiated. Once the location is identified, a repair agent is manually applied to the dent. Existing repair agents such as cement, plaster, paste, resin, or repair glue are used. After the repair agent is applied and solidified, a smoother repair surface is achieved through the combined action of the aforementioned sanding structure, scraper structure, and brush. Furthermore, when applying repair agent to a location on the wooden column, the height of the person may be limited, making it difficult to reach the area to be repaired. In this case, the preferred embodiment can be improved by designing a curved plate 331 as a cavity structure with a removable cap at the top for injecting the repair agent. Furthermore, the cavity structure is filled with a repair agent. The side of the cavity structure facing the wooden column has small openings. When the curved plate moves inward and contacts the wooden column, the cavity structure is preferably an elastic structure, such as an elastic structure made of rubber. Through compression, the cavity structure is deformed, and then the repair agent is squeezed out from the small openings to the position to be repaired to complete the repair. Subsequently, the process of sanding, cutting, or cleaning is completed. The inward movement of the curved plate is achieved by the movement of the moving structure 10.
