[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figures 1-6This invention provides a technical solution: an adjustable indoor building decoration operation platform, including a base 1 and a lifting platform 3. Two uprights 2 are vertically arranged on the upper surface of the base 1. The lifting platform 3 is slidably arranged on the right side of the uprights 2. The height of the lifting platform 3 is adjustable. A drive adjustment mechanism 5 is provided between the lifting platform 3 and the base 1. The drive adjustment mechanism 5 can adjust the position of the lifting platform 3 according to the construction personnel, making it easier for the lifting platform 3 to approach the indoor construction site and increasing construction convenience. A horizontal crossbeam 4 is horizontally arranged on the upper surface of the uprights 2, located above the lifting platform 3, facilitating the subsequent installation of vertical guide wheels. 512 Installation: The drive adjustment mechanism 5 includes two sliding plates 54 slidably sleeved on the upright 2. Extension adjustment components 53, which drive the horizontal movement of the lifting platform 3, are respectively provided between the upper and lower ends of the lifting platform 3 and the two sliding plates 54. The extension adjustment components 53 can change the horizontal extension position of the lifting platform 3, making it easier for construction personnel standing on the lifting platform 3 to approach the construction ground. Simultaneously, the entire adjustment process does not require manual operation, increasing the convenience of adjusting the position of the lifting platform 3. Support components 52 are provided between the front and rear surfaces of the lifting platform 3 and the sliding plates 54, and the support components 52 can adjust the horizontal position of the lifting platform 3. The lifting platform 3 provides support and stability. A winding lifting component 51 is provided between the top of the lifting platform 3 and the upper left surface of the base 1. The winding lifting component 51 includes a vertical guide wheel 512 installed on the lower surface of the crossbeam 4, a side guide wheel 513 provided on the left side of the upright 2, and a lifting cable 511 on the top of the lifting platform 3. A lifting ring is fixed to the upper surface of the lifting platform 3, and the lower end of the lifting cable 511 is fixed to the lifting ring. As the lifting cable 511 moves, it can drive the height adjustment of the lifting platform 3. The lifting cable 511 wraps around the vertical guide wheel 512 and the side guide wheel 513 and is wound around the winding wheel 51. On the upper surface of the left end of the base 1, there are two support seats 514. A rotating shaft 517 is rotatably connected between the two support seats 514. The support seats 514 can support the rotating shaft 517. A winding motor 515 is provided at the front end of the rotating shaft 517. The operation of the winding motor 515 can drive the rotating shaft 517 to rotate. Two winding wheels 516 are sleeved on the rotating shaft 517, which are respectively wound for two lifting steel cables 511. The two winding wheels 516 rotate and respectively wind the two lifting steel cables 511. The change in the length of the lifting steel cables 511 facilitates the vertical movement of the lifting platform 3 to change the construction height.

[0029] In this embodiment, preferably, the extension adjustment component 53 includes two stabilizing seats 537 fixed to opposite surfaces of the sliding plate 54. The extension adjustment component 53 can drive the lifting platform 3 to move and extend in the X-axis direction, adjusting the position of the lifting platform 3 within a certain range, so that the lifting platform 3 is closer to the wall, increasing the convenience of construction personnel's operation. An installation shaft 533 is rotatably arranged between the two stabilizing seats 537, and the stabilizing seats 537 can support the installation shaft 533. At the same time, a bearing is embedded between the installation shaft 533 and the stabilizing seats 537 to facilitate the rotation of the installation shaft 533. A drive motor 536 is provided at the front end of the installation shaft 533. A frame is provided between the drive motor 536 and the sliding plate 54 to increase the installation strength of the drive motor 536. A horizontal plate is provided on the lower surface of the lifting platform 3, which increases the connection between the lifting platform 3 and the wall. The contact area of ​​the lower surface of the lifting platform 3 is increased to enhance the support effect on the lifting platform 3. A fixed rack 531 is provided on the left side of the horizontal plate and is slidably connected to the sliding plate 54. A rotating gear 532 is meshed above the fixed rack 531. The rotating gear 532 is fixedly sleeved on the mounting shaft 533, so that the mounting shaft 533 can drive the rotating gear 532 to rotate. A sprocket 534 is sleeved on both the upper and lower mounting shafts 533. A drive chain 535 is meshed between the two sprockets 534. The drive motor 536 drives the mounting shaft 533 to rotate, which can drive the lower sprocket 534 to rotate. The upper sprocket 534 and the lower sprocket 534 are connected by the drive chain 535, so that the two mounting shafts 533 can rotate synchronously. The two fixed racks 531 move outward to drive the lifting platform 3 to move.

[0030] In summary, when adjusting the height of the lifting platform 3, the winding motor 515 drives the rotating shaft 517 to rotate, and the winding wheel 516 on it rotates with the rotating shaft 517. As the winding wheel 516 rotates, the lifting steel cable 511 gradually winds around the winding wheel 516. The vertical guide wheel 512 and the side guide wheel 513 guide the moving and winding lifting steel cable 511. As the lifting steel cable 511 gradually winds around, it pulls the lifting platform 3 upward, causing the sliding plate 54 to move along the upright 2. This provides guidance and stability for the sliding plate 54 and the lifting platform 3 until the height of the lifting platform 3 is suitable. Construction workers can then stand on the lifting platform 3 at the appropriate height to carry out interior decoration work. When adjusting the horizontal extension position of the lifting platform 3, the drive motor 536 drives the mounting shaft 533 to rotate. The upper and lower mounting shafts 533 are connected by two sprockets 534 and a drive chain 535, allowing the two mounting shafts 533 to rotate synchronously, driving the upper and lower mounting shafts 533 to rotate. The rotating gear 532 rotates, and the fixed rack 531 meshing with the rotating gear 532 rotates and moves to the right, driving the fixed rack 531 and the lifting platform 3 to move to the right. The support plate 524 moves with the lifting platform 3, and the support plate 524 can always support the lifting platform 3. With the cooperation of the rotating gear 532 and the fixed rack 531, the lifting platform 3 is driven to extend to the right, allowing the lifting platform 3 to be closer to the construction wall, which also makes it easier for construction personnel to approach the construction wall, increasing the construction range and convenience. As the lifting platform 3 extends outward, the winding motor 515 works, driving the rotating shaft 517 to rotate in the opposite direction, gradually unfolding the wound lifting steel cable 511, which facilitates the movement of the lifting steel cable 511 with the lifting platform 3. When the lifting platform 3 is in a suitable position, the winding motor 515 and the drive motor 536 stop working, and the lifting steel cable 511 is tilted and stretched to provide suspension support for the extended lifting platform 3, increasing the load-bearing strength and stability of the lifting platform 3.

[0032] Reference Figure 6 This is the second embodiment of the present invention, which differs from the previous embodiment in that...

[0033] In this embodiment, preferably, the surface of the sliding plate 54 is provided with a guide rail 521 located outside the fixed rack 531. The supporting member 52 increases the stability of the lifting platform 3 during its extension and movement, while also increasing the load-bearing capacity and safety of the lifting platform 3. A guide slider 522, which slides into the guide rail 521, is fixedly provided on the outer surface of the fixed rack 531. The guide slider 522 has a T-shaped cross-section. While sliding with the guide rail 521, the guide slider 522 provides support for the fixed rack 531. The function is to increase the stability of the fixed rack 531. Two fixed protrusions 523 are vertically arranged on the front and rear surfaces of the sliding plate 54. L-shaped support plates 524 are provided on both the front and rear surfaces of the sliding plate 54. The support plates 524 can move outward together with the lifting platform 3. At the same time, the support plates 524 and the fixed protrusions 523 cooperate to support and stabilize the lifting platform 3, increasing the load-bearing strength of the lifting platform 3. The left end of the support plate 524 can move through the two fixed protrusions 523 and is exposed on the outside, which does not affect the movement of the support plate 524 as the lifting platform 3 extends.

[0034] In summary, during use, the lifting platform 3 moves outward under the action of the drive adjustment mechanism 5 and the fixed rack 531. The movement of the fixed rack 531 drives the guide slider 522 to move in the guide slide 521. The T-shaped cooperation between the two can prevent the fixed rack 531 from shifting laterally or separating vertically, increasing the stability and safety of the movement extension of the fixed rack 531 and the lifting platform 3. Furthermore, as the lifting platform 3 moves, it drives the support plate 524 to move, and the support plate 524 can always provide vertical support for the lifting platform 3, improving the load-bearing capacity of the lifting platform 3.

[0035] Example 3

[0036] Reference Figure 7 This is the third embodiment of the present invention, which differs from the previous two embodiments in that...

[0037] In this embodiment, preferably, two limiting members 7 are rotatably provided on both the front and rear surfaces of the base 1. By providing the limiting members 7, the decoration platform can be fixed and limited when it stops in a certain place, increasing the contact area and frictional resistance between the decoration platform and the ground, thereby limiting and fixing the position of the decoration platform, increasing the stability and safety of the decoration platform during placement and use. The limiting member 7 includes a fixing plate 71 fixed to the front surface of the base 1. The fixing plate 71 is U-shaped when viewed from the side and circular when viewed from above. A fixing shaft is provided inside the fixing plate 71. A fixing protrusion is fixed to the outer surface of the rotating plate 72 and rotatably sleeved on the fixing shaft. Limiting holes are opened on the upper and lower surfaces of the fixing plate 71 along the circumference of the fixing shaft. The mounting screw 76 cooperates with the limiting holes at different positions and passes through the fixing protrusion to fix the rotating plate. The fixed plate 71 has a U-shaped rotating plate 72, which is rotatably mounted inside the fixed plate 71. The rotating plate 72 has an inner plate 73, whose position is adjustable. A connecting bolt 75 is provided between the two. A limiting screw 74 is vertically mounted on the free end of the inner plate 73. The limiting screw 74 can move up and down, so that the lower end of the limiting screw 74 has a tapered limiting plate that contacts the ground, increasing the frictional resistance with the ground and thus limiting and fixing the entire decoration platform. Multiple adjustment holes are opened on the surface of the rotating plate 72 along its length. The connecting bolt 75 is combined with the adjustment holes at different positions to limit and fix the positions of the inner plate 73 and the rotating plate 72. A mounting screw 76 is provided between the fixed plate 71 and the rotating plate 72 to limit and fix the position of the rotating plate 72.

[0038] In this embodiment, preferably, the lower surface of the base 1 is provided with a movable wheel 6, which facilitates the movement of the entire decoration platform. The lifting platform 3 includes a top plate and a bottom plate, and support columns are provided between the four corners of the two to achieve a tight connection between the top plate and the bottom plate. A safety railing is provided on the upper surface of the bottom plate, and the safety railing can protect the construction workers when they stand on the bottom plate.

[0039] In this embodiment, preferably, the side of the upright 2 is provided with a guide hole for the lifting cable 511 to pass through, which can guide the movement of the lifting cable 511 and prevent the lifting cable 511 from detaching from the side guide wheel 513. The lower surface of the crossbeam 4 and the left side of the upright 2 are provided with a support frame. The vertical guide wheel 512 and the side guide wheel 513 are provided with a rotating shaft between them and the support frame, so that the vertical guide wheel 512 and the side guide wheel 513 can rotate due to frictional resistance as the lifting cable 511 moves, thus playing a guiding role and facilitating the up and down movement of the lifting platform 3.

[0040] In summary, when the renovation platform needs to be fixed during use, the rotating plate 72 stored on the surface of the base 1 is rotated outward around the fixed axis. When the rotation angle of the rotating plate 72 is appropriate, the fixing plate 71 is connected and fixed to the rotating plate 72 using the mounting screws 76. The inner plate 73 inside the rotating plate 72 is moved outward to increase the distance between the inner plate 73 and the rotating plate 72. Then, the inner plate 73 and the rotating plate 72 are connected and fixed using the connecting bolts 75. The longer length of both increases the contact area with the ground, thereby increasing the overall stability of the renovation platform. Then, the limiting screw 74 is rotated to move it downward, causing the conical limiting plate to move downward to contact the ground, increasing the contact area and frictional resistance with the ground, thereby fixing the renovation platform and increasing the stability and safety of the renovation platform.

[0041] Example 4

[0042] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0043] When in use, the construction platform is placed on the ground and fixed to the ground by the limiting component 7, which increases the contact area between the construction platform and the ground, preventing the construction platform from tilting and increasing the stability and safety of the construction platform during construction. Construction workers stand on the lifting platform 3 and can move the lifting platform 3 up or down by winding the lifting component 51, increasing the height range of the lifting platform 3 and making it easier for construction workers to be at a suitable construction height. At the same time, according to the construction workers' construction needs, the horizontal position of the lifting platform 3 can be changed by using the extension adjustment component 53, and the extension position of the lifting platform 3 can be adjusted so that the lifting platform 3 is closer to the wall, increasing the convenience of use for construction workers. Moreover, the support component 52 can always provide support and stability for the lifting platform 3, increasing the load-bearing strength and safety of the lifting platform 3.
