Description

Technical Field

[0001] This invention relates to the field of building platform technology, and more specifically, to a building platform for adjustable interior decoration buildings. Background Technology

[0002] Due to people's home needs, various renovations are frequently required, such as painting ceilings and high walls, and installing electrical wiring. However, because ceilings and high walls are often too tall, further renovations are difficult.

[0003] Currently, construction workers typically use ladders to approach ceilings and high walls for further decoration. However, ladders are prone to shaking and have limited stability, posing a safety hazard to workers standing on them and increasing the risk of falling to the ground. Furthermore, the small standing area of ​​the ladder makes it difficult for workers to maintain their footing, making it challenging to ensure the quality of the decoration.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] In view of the problems in related technologies, the present invention proposes an adjustable interior decoration building platform to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by the present invention is as follows:

[0008] Preferably, the moving component includes a plurality of telescopic hydraulic cylinders located at the bottom of the base, the bottom of the telescopic hydraulic cylinders being connected and fixed to the horizontal plate, and the bottom of the horizontal plate being provided with a plurality of rollers.

[0009] Preferably, in the first-stage lifting assembly, the fixed seat and the horizontal block are respectively connected and fixed to the base and the first adjusting plate; in the second-stage lifting assembly, the fixed seat and the horizontal block are respectively connected and fixed to the first adjusting plate and the second adjusting plate; and in the third-stage lifting assembly, the fixed seat and the horizontal block are respectively connected and fixed to the second adjusting plate and the working surface.

[0010] Preferably, the bottom end of the rotating shaft in the first-stage lifting assembly is connected to the drive motor, and the bottom end of the rotating shaft in both the second-stage lifting assembly and the third-stage lifting assembly is connected to a bottom long gear that cooperates with the adjusting assembly.

[0011] Preferably, the adjustment assembly includes an electric telescopic rod, symmetrically arranged limiting members on both sides of the electric telescopic rod, and three intermediate gears: intermediate gear one, intermediate gear two, and intermediate gear three. Limiting plates are fitted onto the two limiting members. Two limiting rods are symmetrically arranged on the top of the limiting plates. A spring is provided at the bottom of the limiting plates. The top output end of the electric telescopic rod passes through the limiting plates and is connected to a fixed plate. A connecting gear is movably connected at the top center of the fixed plate. The top of the limiting plate is pressed together with the bottom of the fixed plate. The two limiting rods extend through the fixed plate into the connecting gear. The connecting gear is located below intermediate gear one.

[0012] Preferably, a fixing member is fixed to the side of the fixing plate, and a fixing gear is provided on the top of the fixing member. The fixing gear meshes with the top side of the first intermediate gear, the second intermediate gear meshes with the first intermediate gear, the third intermediate gear meshes with the second intermediate gear, and the other side of the third intermediate gear meshes with the bottom long gear.

[0013] Preferably, the intermediate gear three in the adjustment component on the side of the first-stage lifting component meshes with the bottom long gear at the bottom end of the second-stage lifting component, and the intermediate gear three in the adjustment component on the side of the second-stage lifting component meshes with the bottom long gear at the bottom end of the third-stage lifting component.

[0014] Preferably, the bottom of the connecting gear is provided with a limiting groove that cooperates with the limiting rod, the spring is a compression spring, and the intermediate gears one, two, and three on the base, the adjusting plate one, and the adjusting plate two are all movably connected by shafts.

[0015] Preferably, the limiting plate has a through hole at its center that mates with the electric telescopic rod, and two movable holes that mate with the limiting member are symmetrically provided on the side of the limiting plate.

[0016] Preferably, the inclined wheel has a hole in the middle that matches both the rotating shaft and the limiting strip.

[0017] The beneficial effects of this invention are as follows:

[0018] By designing a moving component, a telescopic hydraulic cylinder is activated by a control switch. The telescopic hydraulic cylinder drives the horizontal plate to descend, which in turn drives several rollers to descend, thus lifting the device from the ground. Then, the device is pushed to the construction site. When it reaches the designated position, the telescopic hydraulic cylinder is activated again, which drives the horizontal plate and several rollers to rise. The support column at the bottom of the device comes into contact with the ground, thus fixing the device to the ground.

[0019] The design of the lifting components allows for adjustment of the working surface height. The lifting components at the corresponding positions are activated by adjusting the working surface height. Specifically, the motor in the first-stage lifting component is activated by the control switch. The motor drives the rotating shaft to rotate, which in turn drives the drive gear to rotate. The drive gear drives the gear ring, which in turn drives the inclined wheel to rotate. As the inclined wheel rotates, its top side pushes the top conical roller to rotate. Simultaneously, the conical roller drives the horizontal block to rise, which in turn pushes the top adjustment plate and the second-stage lifting component to rise synchronously.

[0020] By adjusting the component design, the first-stage lifting component can be linked with the second-stage and third-stage lifting components. Specifically, based on the height of the working surface, it is determined whether the second-stage lifting component needs to be activated. If so, the adjustment component on the side of the first-stage lifting component is activated before the first-stage lifting component is activated, i.e., the electric telescopic rod is activated. The electric telescopic rod pushes the fixed plate, connecting gear, and fixing parts upward. Simultaneously with the fixed plate's rise, under the action of the spring and limiting component, the limiting plate rises synchronously against the fixed plate, allowing the limiting rod on the limiting plate to insert into the limiting groove at the bottom of the connecting gear, thus aligning the connecting gear with the intermediate gear. Before contact, it will not rotate. At the same time, the fixed gear plate at the bottom of the fixed component and the fixed plate are an integral structure. Therefore, as the connecting gear rises and gradually contacts the intermediate gear, the fixed gear plate gradually disengages from the intermediate gear. The two actions are synchronized. When the connecting gear and the intermediate gear just make contact, the limiting plate also collides with the limiting component. The limiting plate stops rising under the action of the limiting component, while the electric telescopic rod continues to rise with both the fixed plate and the connecting gear. When the connecting gear is fully engaged with the intermediate gear and the driving gear, the first-stage lifting component can be activated to drive the first-stage adjusting plate and the second-stage lifting component to rise synchronously.

[0031] According to an embodiment of the present invention, an adjustable interior decoration building platform is provided.

[0032] Example 1, as Figure 1As shown in Figure 6, an adjustable interior decoration building platform according to an embodiment of the present invention includes a base 1. The base 1 has several supporting columns 2 at its bottom and a movable component at its bottom. An adjusting plate 6, a second adjusting plate 7, and a working surface 8 are sequentially arranged above the base 1. A safety railing 9 is provided on the top of the working surface 8.

The second adjusting plate 7 and the working surface 8 are connected by a tertiary lifting component. The primary, secondary, and tertiary lifting components have identical structures and are all connected by a fixed base 10 and a movable component. The fixed base 10 consists of a vertical rod 11. The top of the vertical rod 11 is provided with a horizontal block 12. The bottom of the horizontal block 12 is provided with a groove 13. A conical roller 14 is movably connected in the groove 13. The top of the fixed base 10 is provided with a conical roller 15, a rotating shaft 16, and a rotating shaft 20. The rotating shaft 16 is movably connected to the top of the fixed base 10. Limiting strips 17 are fixed on both sides of the rotating shaft 16. An inclined wheel 18 is sleeved on the rotating shaft 16. A gear ring 19 is fixed in the middle of the outer surface of the inclined wheel 18. The top of the rotating shaft 20 is provided with a drive gear 21. The gear ring 19 meshes with the drive gear 21. Adjustment components are provided on the sides of the first-stage lifting assembly, the second-stage lifting assembly, and the third-stage lifting assembly.

[0033] Example 2, as Figure 1As shown in Figure 6, the system includes a base 1, with several support columns 2 at its bottom. A movable assembly is located at the bottom of the base 1. Above the base 1, an adjusting plate 1, an adjusting plate 2, and a working surface 8 are arranged sequentially. A safety railing 9 is located on the top of the working surface 8. The base 1 and the adjusting plate 1 are connected by two symmetrically arranged primary lifting assemblies. The adjusting plate 1 and the adjusting plate 2 are connected by a secondary lifting assembly. The adjusting plate 2 and the working surface 8 are connected by a tertiary lifting assembly. The primary lifting assembly, the secondary lifting assembly, and the movable assembly... The three-stage lifting components have the same structure, each consisting of a fixed base 10 and a vertical rod 11 movably connected to the fixed base 10. The top of the vertical rod 11 has a horizontal block 12, and the bottom of the horizontal block 12 has a groove 13. A conical roller 14 is movably connected within the groove 13. The top of the fixed base 10 has a conical roller 15, a rotating shaft 16, and a rotating shaft 20. The rotating shaft 16 is movably connected to the top of the fixed base 10. Limiting strips 17 are fixed on both sides of the rotating shaft 16. An inclined wheel 18 is fitted onto the rotating shaft 16, and the middle of the outer surface of the inclined wheel 18 is fixed... A gear ring 19 is fixed, and a drive gear 21 is provided on the top of the rotating shaft 20. The gear ring 19 meshes with the drive gear 21. Adjustment components are provided on the sides of the first-stage lifting assembly, the second-stage lifting assembly, and the third-stage lifting assembly. The moving assembly includes several telescopic hydraulic cylinders 3 located at the bottom of the base 1. The bottom of the telescopic hydraulic cylinders 3 is connected and fixed to the horizontal plate 4. Several rollers 5 are provided at the bottom of the horizontal plate 4. The fixed seat 10 and the horizontal block 12 in the first-stage lifting assembly are respectively connected and fixed to the base 1 and the adjustment plate 6. In the secondary lifting assembly, the fixed seat 10 and the horizontal block 12 are respectively connected and fixed to the first adjusting plate 6 and the second adjusting plate 7. In the tertiary lifting assembly, the fixed seat 10 and the horizontal block 12 are respectively connected and fixed to the second adjusting plate 7 and the working surface 8. In the primary lifting assembly, the bottom end of the rotating shaft 20 is connected to the drive motor 22. In both the secondary and tertiary lifting assemblies, the bottom end of the rotating shaft 20 is connected to a bottom long gear 36 that cooperates with the adjusting assembly.It is easy to see from the above design that the height of the working surface 8 can be adjusted by the design of the lifting component. The lifting component at the corresponding position is activated by the height of the working surface. That is, the motor 22 in the first-stage lifting component is activated by the control switch. The motor 22 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the drive gear 21 to rotate. The drive gear 21 drives the gear ring 19. The gear ring 19 drives the inclined wheel 18 to rotate. At the same time as the inclined wheel 18 rotates, its top side pushes the top conical roller 14 to rotate. At the same time as the roller rotates, the conical roller 14 drives the horizontal block 12 to rise. At the same time as the horizontal block 12 rises, it pushes the top adjustment plate 6 and the second-stage lifting component to rise synchronously.

[0034] Example 3, as Figure 1As shown in Figure 6, the system includes a base 1, with several support columns 2 at its bottom. A movable assembly is located at the bottom of the base 1. Above the base 1, an adjusting plate 1, an adjusting plate 2, and a working surface 8 are arranged sequentially. A safety railing 9 is located on the top of the working surface 8. The base 1 and the adjusting plate 1 are connected by two symmetrically arranged primary lifting assemblies. The adjusting plate 1 and the adjusting plate 2 are connected by a secondary lifting assembly. The adjusting plate 2 and the working surface 8 are connected by a tertiary lifting assembly. The primary, secondary, and tertiary lifting assemblies have identical structures and are all supported by a fixed base 10. The system comprises a vertical rod 11 movably connected to the fixed base 10, a horizontal block 12 at the top of the vertical rod 11, a groove 13 at the bottom of the horizontal block 12, a conical roller 14 movably connected within the groove 13, a second conical roller 15, a rotating shaft 16, and a rotating shaft 20 at the top of the fixed base 10, the rotating shaft 16 being movably connected to the top of the fixed base 10, limit strips 17 fixed on both sides of the rotating shaft 16, a sloping wheel 18 sleeved on the rotating shaft 16, a gear ring 19 fixed in the middle of the outer surface of the sloping wheel 18, and a drive gear 21 at the top of the rotating shaft 20, with the gear ring 19 meshing with the drive gear 21. The first-stage lifting assembly, the second-stage lifting assembly, and the third-stage lifting assembly are all equipped with adjustment components on their sides. Each adjustment component includes an electric telescopic rod 23, symmetrically arranged limiting members 24 on both sides of the electric telescopic rod 23, and three intermediate gears: a first intermediate gear 33, a second intermediate gear 34, and a third intermediate gear 35. Limiting plates 25 are fitted onto the two limiting members 24. Two limiting rods 28 are symmetrically arranged on the top of the limiting plates 25. A spring 29 is provided at the bottom of the limiting plates 25, and the top output end of the electric telescopic rod 23 passes through the limiting plates 25 and connects to a fixed plate 30. A connecting gear 31 is movably connected to the top center of the fixed plate 30. The top of the limiting plate 25 is pressed together with the bottom of the fixing plate 30. Two limiting rods 28 extend through the fixing plate 30 into the connecting gear 31. The connecting gear 31 is located below the intermediate gear 33. A fixing member 32 is fixed to the side of the fixing plate 30. A fixing gear is provided on the top of the fixing member 32. The fixing gear meshes with the top side of the intermediate gear 33. The intermediate gear 34 meshes with the intermediate gear 33. The intermediate gear 35 meshes with the intermediate gear 34. The other side of the intermediate gear 35 meshes with the bottom long gear 36.It is clear from the above design that the adjustment component allows the first-stage lifting component to work in conjunction with the second-stage and third-stage lifting components. Specifically, based on the height of the working surface, it is determined whether the second-stage lifting component needs to be activated. If so, the adjustment component on the side of the first-stage lifting component is activated before the first-stage lifting component is activated, i.e., the electric telescopic rod 23 is activated. The electric telescopic rod 23 pushes the fixed plate 30, connecting gear 31, and fixing member 32 upwards. Simultaneously with the rise of the fixed plate 30, under the action of the spring 29 and the limiting member 24, the limiting plate 25 rises synchronously against the fixed plate 30. This allows the limiting rod 28 on the limiting plate 25 to insert into the limiting groove at the bottom of the connecting gear 31, enabling the connecting gear 31 to engage with the intermediate gear. Before wheel 33 contacts, it will not rotate. At the same time, the fixed gear plate at the bottom of the fixing member 32 and the fixing plate 30 are integrated structures. Therefore, as the connecting gear 31 rises and gradually contacts the intermediate gear 33, the fixed gear plate gradually disengages from the intermediate gear 33. The two actions are synchronized. When the connecting gear 31 just contacts the intermediate gear 33, the limiting plate 25 also collides with the limiting member 24. The limiting plate 25 stops rising under the action of the limiting member 24, while the electric telescopic rod 23 continues to rise with the fixing plate 30 and the connecting gear 31. When the connecting gear 31 is fully engaged with the intermediate gear 33 and the driving gear 21, the first-stage lifting assembly can be activated to drive the adjusting plate 6 and the second-stage lifting assembly to rise synchronously.

[0035] Example 4, as Figure 1As shown in Figure 6, the system includes a base 1, with several support columns 2 at its bottom. A movable assembly is located at the bottom of the base 1. Above the base 1, an adjusting plate 1 (6), an adjusting plate 2 (7), and a working surface 8 are arranged sequentially. A safety railing 9 is located on the top of the working surface 8. The base 1 and the adjusting plate 1 (6) are connected by two symmetrically arranged primary lifting assemblies. The adjusting plate 1 (6) and the adjusting plate 2 (7) are connected by a secondary lifting assembly. The adjusting plate 2 (7) and the working surface 8 are connected by a tertiary lifting assembly. The primary lifting assembly, the secondary lifting assembly, and the tertiary lifting assembly... The three lifting components have the same structure and each consists of a fixed base 10 and a vertical rod 11 movably connected to the fixed base 10. The top of the vertical rod 11 has a horizontal block 12, and the bottom of the horizontal block 12 has a groove 13. A conical roller 14 is movably connected within the groove 13. The top of the fixed base 10 has a conical roller 15, a rotating shaft 16, and a rotating shaft 20. The rotating shaft 16 is movably connected to the top of the fixed base 10. Limiting strips 17 are fixed on both sides of the rotating shaft 16. An inclined wheel 18 is fitted onto the rotating shaft 16, and a gear ring 1 is fixed to the center of the outer surface of the inclined wheel 18. 9. A drive gear 21 is provided at the top of the rotating shaft 20. The gear ring 19 meshes with the drive gear 21. Adjustment components are provided on the sides of the first-stage lifting assembly, the second-stage lifting assembly, and the third-stage lifting assembly. The intermediate gear 35 in the adjustment component on the side of the first-stage lifting assembly meshes with the bottom long gear 36 at the bottom of the second-stage lifting assembly. The intermediate gear 35 in the adjustment component on the side of the second-stage lifting assembly meshes with the bottom long gear 36 at the bottom of the third-stage lifting assembly. The bottom of the connecting gear 31 has an opening. The limiting groove cooperates with the limiting rod 28. The spring 29 is a compression spring. The intermediate gears 33, 34, and 35 on the base 1, the adjusting plate 6, and the adjusting plate 7 are all movably connected by shafts. The center of the limiting plate 25 has a through hole 26 that cooperates with the electric telescopic rod 23. The side of the limiting plate 25 has two symmetrical movable holes 27 that cooperate with the limiting member 24. The inclined wheel 18 has a hole in the middle that cooperates with both the rotating shaft 16 and the limiting strip 17. It is not difficult to see from the above design that the limiting groove design allows the limiting rod 28 to rotate and limit the connecting gear 31, preventing the connecting gear 31 from rotating and causing a mismatch between it and the intermediate gear 33 and the driving gear 21, thus preventing them from meshing together.

[0036] In summary, with the help of the above-mentioned technical solution of the present invention, firstly, the telescopic hydraulic cylinder 3 is started by the control switch. The telescopic hydraulic cylinder 3 drives the horizontal plate 4 to descend. The descent of the horizontal plate 4 drives several rollers 5 to descend, thereby lifting the device from the ground. Then, the device is pushed to the construction site. When it reaches the designated position, the telescopic hydraulic cylinder 3 is started again. The telescopic hydraulic cylinder 3 drives the horizontal plate 4 and several rollers 5 to rise. The support column 2 at the bottom of the device comes into contact with the ground, thereby fixing the device on the ground.

[0037] Then, the construction workers enter the working face 8 and activate the corresponding lifting and adjusting components according to the height of the working face. That is, the motor 22 in the first-stage lifting component is activated by the control switch. The motor 22 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the drive gear 21 to rotate, the drive gear 21 drives the gear ring 19, the gear ring 19 drives the inclined wheel 18 to rotate, and the inclined wheel 18 rotates at the same time. Its top side pushes the top conical roller 14 to rotate. At the same time, the conical roller 14 drives the horizontal block 12 to rise. The horizontal block 12 rises and pushes the top adjusting plate 6 and the second-stage lifting component to rise synchronously.

[0038] Based on the height of the working surface, determine whether the secondary lifting assembly needs to be activated. If so, before activating the primary lifting assembly, activate the adjustment assembly on the side of the primary lifting assembly, i.e., activate the electric telescopic rod 23. The electric telescopic rod 23 pushes the fixed plate 30, connecting gear 31, and fixing member 32 upward. As the fixed plate 30 rises, under the action of the spring 29 and the limiting member 24, the limiting plate 25 will rise synchronously against the fixed plate 30, thereby allowing the limiting rod 28 on the limiting plate 25 to be inserted into the limiting groove at the bottom of the connecting gear 31. This prevents the connecting gear 31 from rotating before it contacts the intermediate gear 33. At the same time, the fixing member 32 at the bottom... The fixed gear plate and the fixed plate 30 are an integral structure. Therefore, as the connecting gear 31 rises and gradually contacts the intermediate gear 33, the fixed gear plate gradually disengages from the intermediate gear 33. The two actions are synchronized. When the connecting gear 31 just contacts the intermediate gear 33, the limiting plate 25 also collides with the limiting member 24. The limiting plate 25 stops rising under the action of the limiting member 24, while the electric telescopic rod 23 continues to rise with both the fixed plate 30 and the connecting gear 31. When the connecting gear 31 is fully engaged with the intermediate gear 33 and the driving gear 21, the first-stage lifting assembly can be activated to drive the adjusting plate 6 and the second-stage lifting assembly to rise synchronously.
