DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-5 :

[0034] Example 1:

[0035] This embodiment provides a mobile lifting scaffold for decoration, including a base frame 1 and further comprising:

[0036] The supporting mechanism 2 includes a base 20 provided at the bottom of the base frame 1, a working platform 21 connected to the base frame 1 in a lifting and sliding manner, and a moving mechanism 3 provided below the base 20;

[0037] The electric pulley mechanism 4 includes a rope 40, two electric winders 41 provided on the base 20, and two pulleys 42 provided on the top of the base frame 1. One end of the rope 40 is connected to the electric winder 41 and the other end is wound around the pulley 42 and connected to the working platform 21.

[0038] The moving mechanism 3 includes a moving foot 30 and a plurality of fixed feet 31 disposed below the base 20;

[0039] Among them, the movable foot 30 includes a mounting seat 300 arranged on the peripheral side of the base 20, a support rod 301 installed through the mounting seat 300, a movable wheel 302 installed at the bottom of the support rod 301, and an elastic reset member 303 located in the mounting seat 300, and the two ends of the elastic reset member 303 are axially in conflict with the support rod 301 and the mounting seat 300 respectively.

[0040] The base frame 1 serves as the primary support structure for the entire mobile lift scaffold used for renovations. It bears the weight of other components, such as the base 20, work platform 21, motorized pulley mechanism 4, and ladder 6, and provides a foundation for their installation and securing. The strength and rigidity of the base frame 1 directly impact the overall stability and safety of the scaffold, and it must withstand various loads and forces during construction. The base frame 1 typically has a frame-like structure, such as a square or rectangular frame. The individual members of the frame can be connected together using threads, rivets, or other means to form a stable structure.

[0041] Mounted at the bottom of the base frame 1, the base 20 bears the weight of the entire scaffold and evenly distributes the load to the ground. It also provides a mounting location for the mobile mechanism 3 and other related components within the support mechanism 2, serving as a crucial transitional component between the base frame 1 and the ground. The base 20 is typically a square or rectangular metal plate structure, ensuring a secure and stable connection to the base frame 1. It can be secured to the bottom of the base frame 1 by welding or bolting.

[0042] The work platform 21 provides a work platform for construction workers to carry out decoration work, bearing the weight of construction workers, tools and materials to ensure that construction workers can carry out construction operations safely and comfortably on it, and can be adjusted to different heights according to construction needs. The work platform 21 is generally a square or rectangular flat plate structure. Guardrails can be set around the work platform 21 to prevent construction workers and items from falling from the platform. The work platform 21 can be connected to the base frame 1 in a liftable and sliding manner through a lift sliding mechanism 5. The liftable and sliding connection can be a guide rail slider, a chain sprocket or other sliding connection. The work platform 21 is located above the base frame 1 and can be lifted and lowered relative to the base frame 1 under the action of the electric pulley mechanism 4.

[0043] The electric pulley mechanism 4 enables the lifting and lowering of the work platform 21. By retracting and releasing the rope 40 through the forward and reverse rotation of the electric winder 41, the work platform 21 is raised and lowered along the base frame 1, allowing construction workers to reach construction sites at different heights. This mechanism provides the power and transmission for the raising and lowering of the work platform 21 and is the core component that enables the scaffold's lifting function.

[0044] The main function of the rope 40 is to connect the electric winder 41 and the work platform 21 to achieve force transmission, thereby driving the work platform 21 to perform lifting and lowering movements. It bears the weight of the work platform 21 and the personnel, tools, and materials that may be carried on it. Under the action of the electric winder 41, it changes the height position of the work platform 21 by its own stretching and contraction. The rope 40 is usually a steel wire rope, which can be made of multiple strands of steel wire twisted together. It has a compact structure, high strength and wear resistance, and can withstand large tensile forces. One end of the rope 40 can be fixed to the electric winder 41 by a fixing clamp or welding to ensure that the rope 40 does not fall off during the winding process. The other end of the rope 40 can be fixed to the work platform 21 by a hook, a connector, etc.

[0045] The electric winder 41 serves as the power source for the electric pulley mechanism 4. Its function is to drive the reel to reel in and release the rope 40 through the rotation of the motor, thereby controlling the raising and lowering of the work platform 21. It provides sufficient torque and speed to meet the lifting requirements of work platforms 21 of varying weights, and can be operated in both forward and reverse directions as needed, precisely controlling the ascent and descent of the work platform 21. The electric winder 41 is secured to the base 20 by bolts or welding. The base frame 1 is equipped with a controller for controlling the raising and lowering of the electric winders 41 and is connected to the two electric winders 41 via wires or other electrical connections.

[0046] The main function of the pulley 42 is to change the direction of movement of the rope 40 so that the tension of the electric winder 41 can be effectively transmitted to the working platform 21, thereby realizing the lifting and lowering of the working platform 21. By cooperating with the rope 40, it reduces the friction of the rope 40 during movement, improves the transmission efficiency, and can withstand the pressure caused by the tension of the rope 40 and the weight of the working platform 21. The pulley 42 is usually circular and usually consists of a hub and a rim. The hub is the central part of the pulley 42, which is used to be mounted on the base frame 1 and connected to the shaft so that it can rotate freely. The rim is used to guide the direction of movement of the rope 40, and its outer surface usually has smooth grooves so that the rope 40 can slide smoothly in the grooves, reducing the friction resistance between the rope 40 and the pulley 42. The pulley 42 can be connected to the base frame 1 through a shaft, and the shaft and the base frame 1 can be connected by bearings or direct shaft-hole matching.

[0047] The moving mechanism 3 is an important component of the mobile lifting scaffold for decoration. Its main function is to achieve the overall mobility of the scaffold and its stability during use, thereby improving the flexibility and safety of the scaffold in decoration operations.

[0048] The mounting base 300 is used to mount and support the support rod 301, provides a mounting location for the moving wheel 302, and cooperates with the elastic return member 303 to realize the switching function between the moving wheel 302 and the fixed foot 31. The mounting base 300 is generally a square or circular block structure with a through hole inside for mounting the support rod 301. The mounting base 300 can be fixed to the base 20 by welding or bolting.

[0049] The support rod 301 connects the moving wheel 302 and the mounting seat 300, transmits the force borne by the moving wheel 302 to the mounting seat 300, and realizes the lifting and lowering movement of the moving wheel 302 under the action of the elastic reset member 303. The support rod 301 is usually a slender rod-shaped structure, and its cross-sectional shape can be circular, square or other suitable shapes. The support rod 301 and the mounting seat 300 are connected by a sliding fit or through a bearing so that the support rod 301 can move up and down relatively smoothly in the mounting seat 300. The connection with the moving wheel 302 is usually a fixed connection, such as welding or fastening with bolts, to ensure a reliable connection and effectively transmit the force borne by the moving wheel 302 to the mounting seat 300.

[0050] The mobile wheels 302 enable easy movement of the scaffold on the ground, allowing construction workers to quickly move the scaffold to different construction locations, thereby improving construction efficiency. The mobile wheels 302 are typically round wheels consisting of a hub and a tire. The hub is the center of the wheel and is used to connect the support rods 301 and the tire. The mobile wheels 302 can be connected to the support rods 301 by bolts, welding, or other connection methods.

[0051] When the scaffold is not carrying people or heavy objects, the elastic return member 303 keeps the moving wheel 302 on the ground, facilitating the movement of the scaffold; when the scaffold is carrying people or heavy objects, the pressure is transferred to the support rod 301 through elastic deformation, causing the fixed foot 31 to touch the ground, increasing the stability of the scaffold and preventing movement or shaking during use. The elastic return member 303 is usually a spring. The elastic return member 303 can be connected to the support rod 301 by welding, hooking or other means, so that it can be compressed or stretched as the support rod 301 moves up and down. The other end contacts the mounting seat 300, usually directly against the inner wall of the mounting seat 300 or positioned by some fixed structure to ensure that the spring does not shift or fall off during operation.

[0052] Example 2:

[0053] This embodiment provides a movable lifting scaffold for decoration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] A lifting and sliding mechanism 5 is provided between the base frame 1 and the working platform 21 .

[0055] The lifting and sliding mechanism 5 performs both guiding and bearing functions.

[0056] In terms of guidance, the lifting and sliding mechanism 5 guides the work platform 21 in a specific direction. The slide rail 50 provides a predetermined trajectory for the lifting and lowering of the work platform 21, ensuring that the work platform 21 can only slide in the vertical direction on the base frame 1, preventing the work platform 21 from deflecting, shaking, or other unstable motion during the lifting process.

[0057] Regarding load-bearing, the lifting and sliding mechanism 5 supports the work platform 21 and its load. When heavy objects such as tools or construction workers are placed on the work platform 21, the sliding seat 51 and the slide rail 50 cooperate to transfer this weight to the base frame 1. During the raising and lowering of the work platform 21, the lifting and sliding mechanism 5 withstands dynamic loads, ensuring the stability of the entire structure.

[0058] Example 3:

[0059] This embodiment provides a movable lifting scaffold for decoration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] The lifting and sliding mechanism 5 includes:

[0061] The slide rail 50 is provided on the base frame 1;

[0062] The slide 51 is disposed on the working platform 21 and cooperates with the slide rail 50 .

[0063] The primary function of the slide rail 50 is to provide a guide path for the lifting and lowering of the work platform 21, ensuring that the work platform 21 follows a predetermined linear trajectory during the lifting process, avoiding instabilities such as deviation, shaking, or rotation. It withstands the lateral forces and friction generated by the work platform 21 during the lifting process, ensuring the smooth lifting and lowering of the work platform 21. The slide rail 50 is typically a long metal track with a variety of cross-sectional shapes, with dovetail and rectangular shapes being common. It can be attached to the base frame 1 by welding, integrally formed with the base frame 1, or other methods.

[0064] The function of the slide 51 is to cooperate with the slide rail 50 to connect the work platform 21 to the base frame 1 and realize the lifting and sliding of the work platform 21 relative to the base frame 1. It bears the weight of the work platform 21 and the various forces generated during the lifting process. By sliding on the slide rail 50, the work platform 21 can rise or fall smoothly along the guide direction of the slide rail 50. At the same time, the slide 51 also plays the role of transmitting force and motion, converting the pulling force or thrust applied to the work platform 21 by the electric pulley mechanism 4 into motion along the direction of the slide rail 50.

[0065] Example 4:

[0066] This embodiment provides a movable lifting scaffold for decoration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] Ladders 6 are provided on both sides of the base frame 1 , and a detachable limiting mechanism 7 is provided between the ladders 6 .

[0068] The ladder 6 provides a passage for construction workers to go up and down the working platform 21, making it convenient for construction workers to work at different heights. It is an important facility for personnel to move vertically on the scaffold.

[0069] Example 5:

[0070] This embodiment provides a movable lifting scaffold for decoration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] The ladder 6 comprises:

[0072] A plurality of cross bars 60 are provided on both sides of the base frame 1 in pairs, and each cross bar 60 is provided with a boss 61, and the working platform 21 is provided with a groove matching the boss 61;

[0073] The fixing groove is provided on the cross bar 60 .

[0074] Crossbars 60 form the primary lateral support components of ladder 6, providing construction workers with footholds and handholds for vertical movement on the scaffold. Crossbars 60 may be spaced apart to accommodate climbing steps. Crossbars 60 are typically cylindrical or rectangular strips. Bosses 61 on crossbars 60 engage grooves on work platform 21, connecting and positioning the work platform 21 to the ladder 6 to a certain degree. Crossbars 60 can be fixed to the base in pairs by welding, bolting, or other methods.

[0075] The fixing groove is used to install the limit stop bar 70 of the limit mechanism 7, providing a fixed and installed position for the limit stop bar 70, so that the limit stop bar 70 can be accurately positioned below the work platform 21. When the work platform 21 is engaged with the ladder 6, it limits the work platform 21 and prevents the work platform 21 from accidentally falling or shaking. The fixing groove is generally a groove or hole structure provided on the crossbar 60, which is adapted to the limit stop bar 70 to ensure that the limit stop bar 70 can be stably installed therein.

[0076] Example 6:

[0077] This embodiment provides a movable lifting scaffold for decoration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0078] The limiting mechanism 7 includes:

[0079] Two limit bars 70 are respectively arranged in the fixing grooves of the corresponding cross bars 60;

[0080] When the groove on the working platform 21 is matched with the boss 61 on the crossbar 60 , the limiting stop bar 70 is in conflict with the bottom of the working platform 21 .

[0081] The stop bar 70 is primarily used to limit the work platform 21 when it is raised to the position for engagement with the ladder 6. This prevents the work platform 21 from accidentally dropping or shaking during use, thereby ensuring the safety of construction workers on the work platform 21. By interfering with the bottom of the work platform 21, it limits the vertical displacement of the work platform 21 and increases the stability of the work platform 21 when connected to the ladder 6. The stop bar 70 is generally an elongated structure with a rectangular cross-section. This shape facilitates installation with the fixing slots on the crossbar 60 and provides a larger contact area with the bottom of the work platform 21, effectively achieving the limiting function.

[0082] Example 7:

[0083] This embodiment provides a movable lifting scaffold for decoration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0084] The cross bar 60 and the limiting stop bar 70 are connected by bolts.

[0085] The stop bar 70 is bolted to the crossbar 60, making it easy to install and remove. When installing or replacing the stop bar 70, tightening and loosening the bolts facilitates this operation. Furthermore, the bolted connection provides sufficient strength to prevent the stop bar 70 from falling off the crossbar 60 during operation, ensuring proper operation.

[0086] Example 8:

[0087] This embodiment provides a movable lifting scaffold for decoration, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0088] The support rod 301 is connected to the mounting base 300 by bolts.

[0089] The support rods 301 and mounting bases 300 are connected by bolts, which facilitates installation and disassembly. During scaffold assembly, the bolted connection allows for a certain degree of adjustment in the relative position of the support rods 301 and mounting bases 300. This helps improve installation accuracy, ensuring the accurate positioning of the moving wheels 302 and maintaining good balance and stability during both movement and stationary operation. For example, if the verticality of the support rods 301 deviates during installation, this can be corrected by fine-tuning the bolts.

[0090] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
