Description

Technical Field

[0001] This invention relates to the field of interior decoration technology, specifically to a building construction device for interior decoration. Background Technology

[0002] Before starting interior decoration, construction workers need to remove the coating from the ceiling and balcony. During the interior decoration process, they need to apply putty to the previously coated ceilings and other walls, and also lay wall tiles on the previously coated balcony to complete the interior decoration.

[0003] When removing coatings from indoor ceilings and balconies, workers need to use scaffolding and other climbing equipment to elevate themselves and reach higher areas. Similarly, when applying putty and laying wall tiles, scaffolding is required to elevate workers to complete tasks at height. For example, a Chinese patent (CN206784866U) discloses an interior decoration scaffolding system including two side frames and several footboards. Each side frame consists of two uprights with several horizontal bars between them. Braked casters are installed at the bottom of the uprights, and a platform that can be flipped upwards is located at the outer bottom of the side frame. Several detachable connecting rods are installed between the two side frames. The footboards have slots at both ends, allowing them to engage with the horizontal bars of the two side frames. A Chinese patent with patent number CN209099730U discloses an interior decorator comprising a frame consisting of a support plate and uprights. A portal frame is rotatably mounted on one side of the frame. The portal frame includes a horizontal bar and two vertical bars fixed to the ends of the horizontal bar. The vertical bars are hinged to the uprights. A receiving box is hinged to the horizontal bar, and the opening of the receiving box always faces upward. A pull rope is fixed to the vertical bar, and the free end of the pull rope has a retaining ring. A first hook and a second hook are fixed to the support plate, with the first hook positioned close to the portal frame. A limit block is also provided on the support plate. When the portal frame is flipped upward to a vertical position, the vertical bar abuts against the limit block.

[0004] When workers need to use scaffolding to climb, the lack of ladders and the vertical placement of the scaffolding make it unstable and prone to tipping over, potentially causing injury. Furthermore, the scaffolding is unstable when moved; workers must complete tasks such as applying putty or laying tiles before jumping down to move it. Otherwise, the high center of gravity increases the risk of accidents, delaying construction and reducing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a construction device for interior decoration, which aims to improve the problem that workers are easily injured or even have their decoration efficiency reduced when they climb scaffolding during interior decoration.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Example 1

[0039] like Figure 1 , Figure 2 , Figure 13As shown, to facilitate the removal of coatings, application of putty, and laying of wall tiles during interior decoration work, this invention provides a construction device for interior decoration, comprising a walking assembly 1, a middle plate 3, a support plate 7, a coating mechanism 8, and two sets of lifting assemblies 2. The two sets of lifting assemblies 2 are respectively located on the upper and lower sides of the middle plate 3. The lower end of the lower lifting assembly 2 is connected to the walking assembly 1, and the upper end of the upper lifting assembly 2 is connected to the support plate 7. The coating mechanism 8 can be positioned above the support plate 7, and the coating mechanism 8 and the support plate 7 together form a coating assembly 4. When it is necessary to remove coatings at higher locations or lay wall tiles at higher locations, workers can sit on the support plate 7 and, with the operation of the lifting assembly 2, rise to the higher location to remove the coating using a scraper. The walking assembly 1 can control the movement of the construction device according to the progress of coating removal, changing the previous situation where workers had to jump down to move the device, improving the efficiency of removing coatings or laying wall tiles, and reducing the work risks for workers. When putty needs to be applied, workers can sit on the support plate 7 and raise it to a higher position to apply it manually. Alternatively, an application mechanism 8 can be installed above the support plate 7, and putty can be injected into the application mechanism 8. Under the action of the lifting component 2, the application mechanism 8 contacts the indoor ceiling wall, and under the action of the walking component 1, it moves relative to the ceiling wall to complete the putty application. Or, the application mechanism 8 contacts the indoor vertical side wall, and under the action of the lifting component 2, it slides relative to the vertical side wall to complete the putty application. This changes the previous situation where workers had to jump down to move the device, improves the efficiency of putty application, and reduces the work risk for workers.

[0040] like Figure 3 As shown, in order to enable the device to adjust its position according to the construction progress, the walking component 1 includes a base 5 and four walking wheels 12. The four walking wheels 12 are located at the corners below the base 5. The four walking wheels 12 are divided into two groups. One group of walking wheels 12 controls the walking direction, and the other group of walking wheels 12 provides walking power.

[0041] like Figure 3 , Figure 4 , Figure 5 , Figure 9As shown, a circular groove 52 is provided on the lower side of the base 5. A programmable logic controller (PLC) is installed inside the base 5, and a control panel and remote control are provided on the surface. The PLC is electrically connected to the motor. The PLC consists of a CPU, instruction and data memory, input / output interface, power supply, digital-to-analog conversion and other functional units. The device is controlled by the PLC. Each of the walking wheels 12 has a top shaft 13 at its upper end. The top shaft 13 of the walking wheel 12 is inserted into the base 5 through a bearing connection. A transmission belt 14 and a rotary motor 15 are provided between the two walking wheels 12 for adjusting the walking direction. The rotary motor 15 is inverted and installed in the circular groove 52. The output shaft is provided with a drive wheel. The diameter of the drive wheel is larger than the diameter of the top shaft 13. The transmission belt 14 is in frictional contact with the drive wheel and the top shaft 13. The top shaft 13 of the traveling wheels 12, which provides the power for movement, is fixedly connected to the base 5. The central shafts of the two traveling wheels 12, which provide the power for movement, are connected by a rotating shaft 17. A transmission gear 16 and a drive motor 11 are mounted on the rotating shaft 17. The drive motor 11 is connected to the base 5, and a drive gear is mounted on its output shaft. The drive gear meshes with the transmission gear 16. The operation of the drive motor 11 propels the device to move, adjusting its position and providing support for continuous construction. When the direction of movement needs to be adjusted, the rotary motor 15 operates, driving the transmission belt 14 to rotate, controlling the two traveling wheels 12 to rotate around their axes, thus moving the device in a specific direction. The cooperation of the traveling wheels 12, the rotary motor 15, and the drive motor 11 changes the current situation where scaffolding is inconvenient to adjust its position, improving the flexibility of the device.

[0042] like Figure 10 As shown, to adjust the height of the support plate 7, the lifting assembly 2 includes two sets of vertically distributed scissor plate assemblies 21. Each scissor plate assembly 21 includes four connecting plates, which are divided into two sets. Two connecting plates in each set are staggered and cross-connected by a connecting shaft. The two sets of scissor plate assemblies 21 are hinged at their closest ends. One end of the upper scissor plate assembly 21 is provided with a movable shaft 25, and one end of the lower scissor plate assembly 21 is hinged with a vertical plate. A drive shaft 23 is provided between the two vertical plates. A threaded drive post 22 is threaded through the drive shaft 23 vertically. The end of the threaded drive post 22 is connected to the output shaft of the lifting motor 24. When the height of the support plate 7 needs to be adjusted, the lifting motor 24 controls the threaded drive post 22 to rotate. Because the threaded drive post 22 is threadedly connected to the drive shaft 23, the drive shaft 23 is forced to move in the horizontal plane, changing the tilt angle of the connecting plates and thus adjusting the height of the support plate 7.

[0043] like Figure 11 , Figure 12As shown, in order to achieve a stable connection between the lifting assembly 2 and the base 5, the intermediate plate 3, and the support plate 7, a sliding groove 36 is provided on the upper side of both the base 5 and the intermediate plate 3, and a drive hole 33 is provided inside the groove. The drive hole 33 and the sliding groove 36 are connected. The vertical plate passes through the sliding groove 36. The drive shaft 23 is located inside the drive hole 33. The lifting motor 24 is located at the end of the base 5 or the intermediate plate 3. The lower end of the lifting assembly 2, away from the drive shaft 23, is hinged to the base 5 or the intermediate plate 3. The drive shaft 23 is located inside the drive hole 33, thereby realizing the movable connection between the lower end of the lifting assembly 2 and the base 5 and the intermediate plate 3. The lower sides of the intermediate plate 3 and the support plate 7 are provided with two parallel recessed grooves 31. A second sliding hole 34 is provided between the two recessed grooves 31. The side walls that are far apart from each other are provided with a first sliding hole 32 and a through hole 35. The first sliding hole 32 and the second sliding hole 34 are arranged opposite each other. The movable shaft 25 is arranged through the sliding hole. The upper end of the lifting assembly 2, away from the movable shaft 25, is hinged to the intermediate plate 3 and the support plate 7. The end of the scissor plate assembly 21 extends into the recessed groove 31. The through hole 35 is opposite to the drive hole 33.

[0044] like Figure 15 , Figure 16 , Figure 17 As shown, in order to complete the putty application process by the application mechanism 8, the application mechanism 8 includes a chamber 81 and a cover plate 9. The chamber 81 has an inlet / outlet groove on one end face, and two opposite side walls inside have snap-fit ​​grooves. Two symmetrically arranged extrusion plates 86 are installed inside the chamber 81, and the two extrusion plates 86 are threaded onto both ends of the same bidirectional screw 85. The ends of the bidirectional screw 85 pass through the side walls of the chamber 81 and are connected to the output shaft of the extrusion motor 84. The cover plate 9 has snap-fit ​​posts 93 on both edges. The cover plate 9 passes through the inlet / outlet groove, and the snap-fit ​​posts 93 are located within the snap-fit ​​grooves. The cover plate 9 has an arc-shaped protrusion 92, with an output hole 91 at its uppermost end. A scraper 94 is installed on the arc-shaped protrusion 92, and the scraper 94 is inclined, with its upper end slightly higher than the upper end of the arc-shaped protrusion 92. The extrusion motor 84 controls the rotation of the bidirectional screw 85, which in turn controls the two extrusion plates 86 to move closer together, reducing the space of the putty in the chamber 81 and forcing the putty to be output from the output hole 91 and adhere to the wall. Under the control of the traveling assembly 1, the cover plate 9 moves relative to the wall, thereby allowing the putty to be applied to a larger area of ​​the wall. During the movement of the cover plate 9, the scraper 94 scrapes the putty to form a smooth surface.

[0045] like Figure 14 , Figure 15As shown, after applying putty to the interior ceiling, the chamber 81 can be controlled to rotate around its central axis to smooth the putty under the action of the scraper 94. To achieve this smoothing, the upper side of the support plate 7 has an installation groove 72, within which a drive gear 74 is installed. A rotating gear 73 meshes with the side of the drive gear 74 and is mounted on the output shaft of a second motor. A connecting shaft 75 is located on the upper side of the drive gear 74. A sleeve 82 and a support wheel 83 are located below the chamber 81. The sleeve 82 is fitted onto the connecting shaft 75, and the support wheel 83 contacts the drive gear 74. Under the operation of the second motor, the rotating gear 73 controls the drive gear 74 to rotate, thereby controlling the chamber 81 to rotate around its central axis, completing the smoothing of the putty layer.

[0046] like Figure 14 , Figure 15 As shown, a side shaft 71 is provided on the vertical side of the support plate 7, and a sleeve 82 and a support wheel 83 are provided below the chamber body 81. The sleeve 82 is fitted onto the side shaft 71, and the support wheel 83 contacts the drive support plate 7. When applying putty or finishing the interior vertical walls, the chamber body 81 can be vertically set on the side of the support plate 7, and its lifting and lowering can be controlled by the lifting component 2 to complete the application of putty to the vertical walls. Example 2

[0047] like Figure 1 , Figure 2 , Figure 13As shown, to facilitate the removal of coatings, application of putty, and laying of wall tiles during interior decoration work, this invention provides a construction device for interior decoration, comprising a walking assembly 1, a middle plate 3, a support plate 7, a coating mechanism 8, and two sets of lifting assemblies 2. The two sets of lifting assemblies 2 are respectively located on the upper and lower sides of the middle plate 3. The lower end of the lower lifting assembly 2 is connected to the walking assembly 1, and the upper end of the upper lifting assembly 2 is connected to the support plate 7. The coating mechanism 8 can be positioned above the support plate 7, and the coating mechanism 8 and the support plate 7 together form a coating assembly 4. When it is necessary to remove coatings at higher locations or lay wall tiles at higher locations, workers can sit on the support plate 7 and, with the operation of the lifting assembly 2, rise to the higher location to remove the coating using a scraper. The walking assembly 1 can control the movement of the construction device according to the progress of coating removal, changing the previous situation where workers had to jump down to move the device, improving the efficiency of removing coatings or laying wall tiles, and reducing the work risks for workers. When putty needs to be applied, workers can sit on the support plate 7 and raise it to a higher position to apply it manually. Alternatively, an application mechanism 8 can be installed above the support plate 7, and putty can be injected into the application mechanism 8. Under the action of the lifting component 2, the application mechanism 8 contacts the indoor ceiling wall, and under the action of the walking component 1, it moves relative to the ceiling wall to complete the putty application. Or, the application mechanism 8 contacts the indoor vertical side wall, and under the action of the lifting component 2, it slides relative to the vertical side wall to complete the putty application. This changes the previous situation where workers had to jump down to move the device, improves the efficiency of putty application, and reduces the work risk for workers.

[0048] like Figure 3 As shown, in order to enable the device to adjust its position according to the construction progress, the walking component 1 includes a base 5 and four walking wheels 12. The four walking wheels 12 are located at the corners below the base 5. The four walking wheels 12 are divided into two groups. One group of walking wheels 12 controls the walking direction, and the other group of walking wheels 12 provides walking power.

[0049] like Figure 3 , Figure 4 , Figure 5 , Figure 9As shown, a circular groove 52 is provided on the lower side of the base 5. A programmable logic controller (PLC) is installed inside the base 5, and a control panel and remote control are provided on the surface. The PLC is electrically connected to the motor. The PLC consists of a CPU, instruction and data memory, input / output interface, power supply, digital-to-analog conversion and other functional units. The device is controlled by the PLC. Each of the walking wheels 12 has a top shaft 13 at its upper end. The top shaft 13 of the walking wheel 12 is inserted into the base 5 through a bearing connection. A transmission belt 14 and a rotary motor 15 are provided between the two walking wheels 12 for adjusting the walking direction. The rotary motor 15 is inverted and installed in the circular groove 52. The output shaft is provided with a drive wheel. The diameter of the drive wheel is larger than the diameter of the top shaft 13. The transmission belt 14 is in frictional contact with the drive wheel and the top shaft 13. The top shaft 13 of the traveling wheels 12, which provides the power for movement, is fixedly connected to the base 5. The central shafts of the two traveling wheels 12, which provide the power for movement, are connected by a rotating shaft 17. A transmission gear 16 and a drive motor 11 are mounted on the rotating shaft 17. The drive motor 11 is connected to the base 5, and a drive gear is mounted on its output shaft. The drive gear meshes with the transmission gear 16. The operation of the drive motor 11 propels the device to move, adjusting its position and providing support for continuous construction. When the direction of movement needs to be adjusted, the rotary motor 15 operates, driving the transmission belt 14 to rotate, controlling the two traveling wheels 12 to rotate around their axes, thus moving the device in a specific direction. The cooperation of the traveling wheels 12, the rotary motor 15, and the drive motor 11 changes the current situation where scaffolding is inconvenient to adjust its position, improving the flexibility of the device.

[0050] like Figure 10 As shown, to adjust the height of the support plate 7, the lifting assembly 2 includes two sets of vertically distributed scissor plate assemblies 21. Each scissor plate assembly 21 includes four connecting plates, which are divided into two sets. Two connecting plates in each set are staggered and cross-connected by a connecting shaft. The two sets of scissor plate assemblies 21 are hinged at their closest ends. One end of the upper scissor plate assembly 21 is provided with a movable shaft 25, and one end of the lower scissor plate assembly 21 is hinged with a vertical plate. A drive shaft 23 is provided between the two vertical plates. A threaded drive post 22 is threaded through the drive shaft 23 vertically. The end of the threaded drive post 22 is connected to the output shaft of the lifting motor 24. When the height of the support plate 7 needs to be adjusted, the lifting motor 24 controls the threaded drive post 22 to rotate. Because the threaded drive post 22 is threadedly connected to the drive shaft 23, the drive shaft 23 is forced to move in the horizontal plane, changing the tilt angle of the connecting plates and thus adjusting the height of the support plate 7.

[0051] like Figure 11 , Figure 12As shown, in order to achieve a stable connection between the lifting assembly 2 and the base 5, the intermediate plate 3, and the support plate 7, a sliding groove 36 is provided on the upper side of both the base 5 and the intermediate plate 3, and a drive hole 33 is provided inside the groove. The drive hole 33 and the sliding groove 36 are connected. The vertical plate passes through the sliding groove 36. The drive shaft 23 is located inside the drive hole 33. The lifting motor 24 is located at the end of the base 5 or the intermediate plate 3. The lower end of the lifting assembly 2, away from the drive shaft 23, is hinged to the base 5 or the intermediate plate 3. The drive shaft 23 is located inside the drive hole 33, thereby realizing the movable connection between the lower end of the lifting assembly 2 and the base 5 and the intermediate plate 3. The lower sides of the intermediate plate 3 and the support plate 7 are provided with two parallel recessed grooves 31. A second sliding hole 34 is provided between the two recessed grooves 31. The side walls that are far apart from each other are provided with a first sliding hole 32 and a through hole 35. The first sliding hole 32 and the second sliding hole 34 are arranged opposite each other. The movable shaft 25 is arranged through the sliding hole. The upper end of the lifting assembly 2, away from the movable shaft 25, is hinged to the intermediate plate 3 and the support plate 7. The end of the scissor plate assembly 21 extends into the recessed groove 31. The through hole 35 is opposite to the drive hole 33.

[0052] like Figure 15 , Figure 16 , Figure 17 As shown, in order to complete the putty application process by the application mechanism 8, the application mechanism 8 includes a chamber 81 and a cover plate 9. The chamber 81 has an inlet / outlet groove on one end face, and two opposite side walls inside have snap-fit ​​grooves. Two symmetrically arranged extrusion plates 86 are installed inside the chamber 81, and the two extrusion plates 86 are threaded onto both ends of the same bidirectional screw 85. The ends of the bidirectional screw 85 pass through the side walls of the chamber 81 and are connected to the output shaft of the extrusion motor 84. The cover plate 9 has snap-fit ​​posts 93 on both edges. The cover plate 9 passes through the inlet / outlet groove, and the snap-fit ​​posts 93 are located within the snap-fit ​​grooves. The cover plate 9 has an arc-shaped protrusion 92, with an output hole 91 at its uppermost end. A scraper 94 is installed on the arc-shaped protrusion 92, and the scraper 94 is inclined, with its upper end slightly higher than the upper end of the arc-shaped protrusion 92. The extrusion motor 84 controls the rotation of the bidirectional screw 85, which in turn controls the two extrusion plates 86 to move closer together, reducing the space of the putty in the chamber 81 and forcing the putty to be output from the output hole 91 and adhere to the wall. Under the control of the traveling assembly 1, the cover plate 9 moves relative to the wall, thereby allowing the putty to be applied to a larger area of ​​the wall. During the movement of the cover plate 9, the scraper 94 scrapes the putty to form a smooth surface.

[0053] like Figure 14 , Figure 15As shown, after applying putty to the interior ceiling, the chamber 81 can be controlled to rotate around its central axis to smooth the putty under the action of the scraper 94. To achieve this smoothing, the upper side of the support plate 7 has an installation groove 72, within which a drive gear 74 is installed. A rotating gear 73 meshes with the side of the drive gear 74 and is mounted on the output shaft of a second motor. A connecting shaft 75 is located on the upper side of the drive gear 74. A sleeve 82 and a support wheel 83 are located below the chamber 81. The sleeve 82 is fitted onto the connecting shaft 75, and the support wheel 83 contacts the drive gear 74. Under the operation of the second motor, the rotating gear 73 controls the drive gear 74 to rotate, thereby controlling the chamber 81 to rotate around its central axis, completing the smoothing of the putty layer.

[0054] like Figure 14 , Figure 15 As shown, a side shaft 71 is provided on the vertical side of the support plate 7, and a sleeve 82 and a support wheel 83 are provided below the chamber body 81. The sleeve 82 is fitted onto the side shaft 71, and the support wheel 83 contacts the drive support plate 7. When applying putty or finishing the interior vertical walls, the chamber body 81 can be vertically set on the side of the support plate 7, and its lifting and lowering can be controlled by the lifting component 2 to complete the application of putty to the vertical walls.

The support mechanism 6 includes a support plate assembly 61 and an adjustment device 62. The upper end of the adjustment device 62 is connected to the base 5, and the lower end is connected to the support plate assembly 61. The support plate assembly 61 includes a main plate 64 and two side plates 69 symmetrically arranged on both sides of the main plate 64. Both side walls of the main plate 64 are provided with a snap-fit ​​plate 65. The snap-fit ​​plate 65 is connected to the main plate 64 with a sliding hole 66. A drive rod 67 and a threaded rod 68 are provided in the sliding hole 66. The threaded rod 68 is vertical and its thread passes through the drive rod 67, and its end is connected to the output shaft of the first motor. The side walls of the two side plates 69 that are close to each other are provided with snap-fit ​​grooves 63. The snap-fit ​​plate 65 is located in the snap-fit ​​groove 63. The two side plates 69 are connected to the two ends of the drive rod 67 by connecting bolts. The adjusting device 62 includes a scissor plate assembly 21, a lifting motor 24, and a threaded drive column 22. A sliding plate is hinged to the end of the scissor plate assembly 21. Sliding grooves 51 are provided on the side walls of the main board 64 and the base 5, with the sliding plate located within the grooves. The other end of the adjusting device 62 is hinged to both the main board 64 and the base 5. During operation, the adjusting device 62 lowers the support plate assembly 61, bringing its lower surface into close contact with the interior floor wall. Under the action of the first motor, the threaded rod 68 controls the movement of the drive rod 67, adjusting the position of the side plate 69 relative to the main board 64. The side plate 69 protrudes from the base 5, increasing the stability of the device.
