[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides: a movable lifting platform with quick-folding and storage fixture, such as... Figures 1-4 As shown, the system includes a movable base 1, a fixed seat 2 mounted on the upper part of the base 1, a support frame 3 rotatably mounted on the middle of the fixed seat 2, and a lifting assembly 8 for driving the platform 9 to rise and fall mounted on the middle of the support frame 3. The platform 9 is rotatably positioned on the side of the lifting assembly 8. The support frame 3 and the platform 9 can be rotatably folded to the upper part of the base 1, and the folded support frame 3 and platform 9 are horizontal with the base 1. The base 1 is the basic support component for the quick-folding and storage of the tooling of the entire movable lifting platform. Its mobility gives the tooling flexible transportation capabilities and allows the working position to be adjusted according to usage requirements. The fixed seat 2 is mounted on the upper part of the base 1 and provides a reference for the rotational installation of the support frame 3. Through the rotational cooperation with the support frame 3, the folding and unfolding actions of the support frame 3 are realized. The support frame 3 serves as the mounting carrier for the lifting assembly 8. It not only bears the weight of the lifting assembly 8 but also drives the lifting assembly 8 and platform 9 to move synchronously through its own rotation. The lifting assembly 8 is installed in the middle of the support frame 3, and its function is to drive the platform 9 to achieve lifting and lowering, meeting the needs of operations at different heights. The platform 9 is rotatably positioned on the side of the lifting assembly 8, serving as the working surface for the tooling, used to place materials to be worked on or for personnel operation. In the non-use state, since the support frame 3 can rotate around the fixed base 2 and the platform 9 can rotate around the lifting assembly 8, the support frame 3 and platform 9 can be folded synchronously onto the upper part of the base 1, and after folding, both are horizontal with the base 1. This design maximizes the reduction of the tooling's storage volume, avoiding the space-consuming problem of traditional lifting platforms, significantly improving site space utilization, reducing storage and management costs, and facilitating subsequent transportation and redeployment.
[0024] Preferably, the support frame 3 is rotatably mounted on the center of the fixed base 2 via a rotating shaft 4, and a limiting block 5 is installed on the side wall of the fixed base 2 to limit the rotation angle of the support frame 3. The rotating shaft 4 is the core transmission component connecting the support frame 3 and the fixed base 2. Its cylindrical structure ensures that the support frame 3 can rotate stably around the fixed base 2, providing a rotation reference for the folding and unfolding of the support frame 3, and realizing the switching between the two states of the support frame 3 in operation unfolding and storage folding. The limiting block 5 installed on the side wall of the fixed base 2 is used to limit the rotation angle of the support frame 3 to prevent the support frame 3 from structural misalignment or functional failure due to excessive rotation. When the support frame 3 needs to be unfolded for operation, the external force drives the support frame 3 to rotate around the pivot 4 along the middle of the fixed base 2. As the rotation angle of the support frame 3 increases, its side wall will gradually approach the limiting block 5. When the support frame 3 contacts the limiting block 5, the limiting block 5 generates a blocking force, restricting the support frame 3 from continuing to rotate and keeping it at a fixed angle that meets the operation requirements. When it needs to be folded and stored, the support frame 3 is driven to rotate around the pivot 4 in the opposite direction. At this time, the limiting block 5 can prevent the support frame 3 from rotating excessively in the opposite direction, ensuring that the support frame 3 can be accurately folded to the upper part of the base 1 and kept horizontal with the base 1, ensuring the accuracy of the folding action and the stability of the structure.
[0025] Furthermore, a stepper motor 6 is installed at one end of the rotating shaft 4 to drive its rotation, and the other end of the rotating shaft 4 extends to the outside of the fixed base 2 and is equipped with a locking component 7. The stepper motor 6 features high control precision and stable speed, and can output a precise rotation angle according to requirements, thereby driving the rotating shaft 4 to achieve quantitative rotation, providing power support for the precise unfolding and folding of the support frame 3; the locking component 7 at the other end of the rotating shaft 4 is used to lock the rotating shaft 4 after the rotating shaft 4 drives the support frame 3 to adjust to the target angle, preventing the rotating shaft 4 from rotating accidentally during the use of the tooling and ensuring structural stability. When the support frame 3 rotates to the target angle, the stepper motor 6 stops working, and at this time the locking component 7 is tightened, so that the locking component 7 fits tightly against the outer wall of the fixed base 2. The mechanical locking action restricts the rotation of the rotating shaft 4, thereby stably fixing the support frame 3 at the target angle, preventing the support frame 3 from shaking during operation and shifting during storage, ensuring the safety of tooling use and storage effect.
[0026] The stepper motor 6 has selectable parameters: step angle 1.8°, holding torque 1.8-2.5 N·m, and no-load speed 300-600 rpm. The 1.8° step angle, combined with 16 microsteps, can achieve high-precision angle control of 0.1125°, ensuring that the support frame 3 can be accurately folded to be horizontal with the base 1 or unfolded to the working angle limited by the limit block 5; the holding torque of 1.8-2.5 N·m is sufficient to support part of the weight of the support frame 3, the lifting assembly 8, and the platform 9, preventing slippage due to excessive load when stationary; the speed of 300-600 rpm ensures smooth folding and unfolding operations.
[0027] Furthermore, the lifting assembly 8 includes a servo motor 81 mounted on the side wall of the support frame 3, with a lead screw 82 keyed to the output end of the servo motor 81. The servo motor 81 serves as the lifting power source, providing stable and controllable power for the lifting of the platform 9. The lead screw 82, keyed to the output end of the servo motor 81, is a key component for power transmission and motion conversion. The lead screw 82 is rotatably mounted in the middle of the support frame 3, and its threaded structure provides the basis for the linear motion of the subsequent movable block 83. When the platform 9 needs to be lifted, the servo motor 81 is powered on and starts, its output end rotating around its own axis. Because the lead screw 82 is keyed to the output end of the servo motor 81, the lead screw 82 rotates synchronously with the output end of the servo motor 81. The support frame 3 limits the rotation of the lead screw 82, ensuring that the lead screw 82 rotates only along its own axis and does not deviate radially.
[0028] The servo motor 81 can be configured with a rated power of 400-750W, a continuous torque of 2-5N·m, and a rated speed of 1500-3000rpm. The continuous torque of 2-5N·m can be effectively converted into lifting force through the lead screw 82 to meet the lifting load of the platform 9 and the load. The rated speed of 1500-3000rpm is reduced by the lead screw 82 to ensure efficiency during operation and to prevent the platform 9 from shaking due to excessive speed.
[0029] It is worth noting that the lead screw 82 is rotatably mounted in the middle of the support frame 3, and the middle of the lead screw 82 is internally threaded with a movable block 83 that is rotatably connected to the platform 9. The thread structure of the lead screw 82 matches the internal thread of the movable block 83, which can convert its own rotational motion into the linear motion of the movable block 83; the movable block 83 is rotatably connected to the platform 9, realizing the transmission of power to the platform 9. When the lead screw 82 rotates under the drive of the servo motor 81, the movable block 83 will move linearly along the axis of the lead screw 82 because the movable block 83 is threadedly engaged with the lead screw 82 and the support frame 3 restricts the rotation of the movable block 83. The movable block 83 is rotatably connected to the platform 9, so the up and down movement of the movable block 83 will drive the platform 9 to move up and down synchronously, realizing the lifting and lowering of the platform 9. When it needs to be folded for storage, since the platform 9 can rotate around the movable block 83, while the support frame 3 rotates and folds around the fixed seat 2, the platform 9 can rotate around the movable block 83 to a state that fits against the support frame 3. Finally, it will fold up to the upper part of the base 1 together with the support frame 3, keeping it horizontal with the base 1, and further compressing the storage volume.
[0030] Specifically, platform 9 is rotatably connected to movable block 83 via connecting rod 10. Both ends of connecting rod 10 extend to both sides of movable block 83 and are fitted with fasteners 11 to restrict the rotation of platform 9. Connecting rod 10 is an intermediate component connecting platform 9 and movable block 83. Its two ends form a rotating pair with movable block 83 and platform 9 respectively, ensuring that the linear motion of movable block 83 can be transmitted to platform 9 to achieve lifting and lowering, and providing a rotation axis for folding and rotating platform 9. The fasteners 11 at both ends of connecting rod 10 are used to control the rotation state of platform 9. During tooling operation, they lock the relative position of platform 9 and connecting rod 10 to prevent platform 9 from shaking. When folding is required, the lock is released to allow platform 9 to rotate around connecting rod 10. In operation, tighten fastener 11 so that it fits tightly against the end of connecting rod 10 and the side wall of movable block 83, restricting the relative rotation of connecting rod 10, movable block 83, and platform 9. At this time, when movable block 83 moves up and down along lead screw 82, it drives platform 9 to rise and fall smoothly through connecting rod 10. Platform 9 always maintains a horizontal working state, avoiding material falling or personnel safety risks caused by rotation.
[0031] More specifically, a shelf 12 is installed on the side wall of the support frame 3, and the shelf 12 is horizontal when the support frame 3 is folded. The shelf 12 is installed on the side wall of the support frame 3 to provide temporary storage space for tools, accessories or small materials needed for operation, so as to avoid the reduction of work efficiency or safety hazards caused by tools scattering. The state of the shelf 12 changes with the rotation of the support frame 3. When the support frame 3 is folded, the shelf 12 is horizontal. This design ensures that the shelf 12 does not take up extra space when stored, and can continue to play a storage function when folded.
