Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to an aluminum alloy lifting platform. Background Technology

[0002] Aluminum alloy lifting platforms, as lightweight and efficient lifting equipment, are widely used in construction decoration, equipment maintenance, and high-altitude operations. Their main structure typically includes a base, a lifting frame, and an operating platform. The lifting frame raises and lowers the operating platform through telescopic movement. In existing technologies, the lifting frame often uses multiple sections of rods connected by sliding or hinged joints to achieve height adjustment.

[0003] However, existing aluminum alloy lifting platforms have some shortcomings in design and use. For example, the telescopic connection of the lifting rod often relies on simple sliding or guide rail structures, which are difficult to effectively limit the telescopic stroke, potentially leading to overtravel or structural instability under high loads or high-altitude operations. Furthermore, the connection methods between lifting rods are usually quite traditional, with insufficient stability in sliding and snap-fit ​​joints, making them prone to wear or loosening over long-term use, affecting the overall safety and service life of the lifting platform. Additionally, existing lifting drive components are generally installed externally or inside the base, with a relatively simple connection method to the lifting rod, resulting in low transmission efficiency and difficulty in adapting to complex lifting requirements. Some lifting platforms use limit devices to control the stroke, but these limit structures are often simply designed and difficult to integrate effectively with the internal structure of the lifting rod, further limiting the stability and practicality of the lifting platform.

[0004] Therefore, further improvements are still needed in the existing technology regarding the stability of the telescopic connection of the boom, the accuracy of stroke control, and the optimization of the transmission structure, in order to meet the higher requirements for safety and efficiency in high-altitude operations.

[0025] Example 1

[0026] Please see Figures 1 to 4 This embodiment provides an aluminum alloy lifting platform 1, which aims to solve the problems of insufficient stability of the telescopic connection of the lifting rod 112, inaccurate stroke control, and low efficiency of the transmission structure in the prior art.

[0027] The aluminum alloy lifting platform 1 includes a base 11, a lifting frame 12 fixed on the base 11, and an operating platform 13 fixed on the top of the lifting frame 12. The base 11 is made of high-strength aluminum alloy, featuring lightweight and high strength to ensure the stability of the overall structure. The bottom of the base 11 has a rectangular frame structure with a flat upper surface for fixing the lifting frame 12. The base 11 also has reserved space to accommodate the lifting drive mechanism 125. The operating platform 13, fixed to the top of the lifting frame 12, is made of aluminum alloy sheet with an anti-slip texture to ensure the safety of operators working at height.

[0028] The lifting frame 12 is the core component of this embodiment, consisting of at least two longitudinally telescopically connected lifting rods 112. In this embodiment, the lifting frame 12 includes at least three lifting rods 112: a bottom lifting rod 112, a middle lifting rod 112, and a top lifting rod 112. Each lifting rod 112 is made of high-strength hollow aluminum alloy profile with a rectangular cross-section to ensure sufficient structural strength and rigidity. Each lifting rod 112 has a longitudinally extending transmission cavity 122 inside its cross-section. The transmission cavity 122 is a rectangular cavity that runs the entire length of the lifting rod 112 and is used to accommodate the lifting drive component 1253. The design of the transmission cavity 122 not only optimizes the layout of the lifting drive component 1253 and reduces external space occupation, but also improves transmission efficiency through the rational utilization of internal space.

[0029] The bottom lifting rod 112 is bolted to the upper surface of the base 11 to ensure a stable connection. The top lifting rod 112 is welded or bolted to the operating platform 13, with reinforcing ribs at the connection to enhance the structure's torsional resistance. The middle lifting rod 112, bottom lifting rod 112, and top lifting rod 112 are telescopically connected to achieve the lifting function. To ensure the smoothness and safety of the telescopic process, the inner walls of the lifting rods 112 below the top (i.e., the bottom lifting rod 112 and the middle lifting rod 112) are provided with limiting structures to restrict the telescopic stroke. The limiting structure includes a limiting boss and a limiting groove on the inner wall. The limiting boss is a rectangular protrusion; the limiting groove is adapted to the protrusion on the outer wall of the adjacent lifting rod 112. When the lifting rod 112 extends or retracts to the set stroke, the boss and the groove engage with each other, restricting further telescopic movement, thereby effectively preventing the stroke from exceeding the limit or structural instability.

[0030] Each section of the lifting rod 112 has a sliding structure 123 and a snap-fit ​​structure 124 adapted to the sliding structure 123 on its side wall to achieve a stable connection between adjacent lifting rods 112. The sliding structure 123 includes a limiting slider 127, and the snap-fit ​​structure 124 includes a limiting groove 126 provided on the outer wall of the lifting rod 112. There are two sets of limiting grooves 126, which are vertically arranged on opposite sides of the outer wall of the lifting rod 112, and their length extends longitudinally along the lifting rod 112. The limiting slider 127 is a rectangular slider adapted to the limiting groove 126, made of high-strength nylon material, with a smooth surface to reduce frictional resistance. The limiting slider 127 is fixed to the inner wall of the adjacent lifting rod 112 and achieves a sliding connection by embedding it in the limiting groove 126. The cooperation between the limiting groove 126 and the limiting slider 127 ensures that the lifting rod 112 maintains a stable relative position during the extension and retraction process, reducing wear or loosening caused by long-term use, thereby significantly improving the overall stability and service life of the lifting platform.

[0031] To drive the telescopic movement of the lifting frame 12, this embodiment includes a lifting drive mechanism 125 within the base 11. The lifting drive mechanism 125 includes a worm gear 1251 installed inside the base 11 and a worm wheel 1252 meshing with the worm gear 1251. The worm gear 1251 is made of high-strength steel and is fixed to the drive cavity inside the base 11 by bearings. One end of the worm gear 1251 is connected to the motor output shaft, and its speed is adjustable. The worm wheel 1252 and the worm gear 1251 form a highly efficient meshing transmission, ensuring high torque output and precise motion control. The worm wheel 1252 is connected to the lifting drive component 1253 via a drive shaft. The lifting drive component 1253 includes a wire rope and a pulley system disposed within the transmission cavity 122. One end of the wire rope is fixed to the bottom of the top lifting rod 112, and the other end passes around the pulley system and connects to the drive shaft of the worm wheel 1252. The pulley block includes multiple fixed pulleys and movable pulleys. The fixed pulleys are fixed to the top of the transmission cavity 122, and the movable pulleys are connected to the lifting rod 112. Through the multiplier effect of the pulley block, the load requirement of the motor is reduced and the transmission efficiency is improved.

[0032] In actual operation, the motor drives the worm gear 1251 to rotate, which in turn drives the worm wheel 1252 to rotate. The worm wheel 1252 pulls the wire rope through the transmission shaft. Guided by the pulley block, the wire rope drives the top lifting rod 112 and the middle lifting rod 112 to move longitudinally. The sliding of the limit slider 127 within the limit groove 126 ensures the smooth movement of the lifting rod 112, while the cooperation between the limit boss and the groove limits the extension and retraction stroke, preventing overextension or overretraction. When the lift needs to be raised to a specified height, the operator adjusts the lifting speed by controlling the motor speed. The precise control of the servo motor ensures the smooth lifting of the operating platform 13, meeting the precision requirements of high-altitude operations.

[0033] The aluminum alloy lifting platform 1 of this embodiment achieves the following technical advantages through the above design: First, the transmission cavity 122 integrates the lifting drive component 1253 inside the lifting rod 112, optimizing space utilization, improving transmission efficiency, and reducing the exposure of external components, thus lowering maintenance difficulty. Second, the combination of the limiting structure and the sliding structure 123 effectively controls the telescopic stroke and enhances connection stability, solving the problems of stroke exceeding limits and structural loosening in the prior art. Third, the adoption of the worm gear 1251-worm wheel 1252 transmission mechanism provides high torque control, adapting to complex lifting requirements and improving the reliability and safety of the equipment. In addition, the use of aluminum alloy material makes the overall equipment lightweight, easy to move and install, and suitable for various operating scenarios. The aluminum alloy lifting platform 1 of this embodiment, through reasonable structural design and efficient transmission system, significantly improves the stability, safety, and efficiency of the equipment, overcomes the shortcomings of the prior art, and provides a reliable solution for high-altitude operations. This design is compact, easy to operate, and suitable for various scenarios such as building decoration, equipment maintenance, and high-altitude operations, possessing high practical value and market prospects.

[0034] Example 2

[0035] Based on Embodiment 1, this embodiment further optimizes the structure of the aluminum alloy lifting platform 1, increasing its mobility, stability, and ease of operation to adapt to a wider range of high-altitude work scenarios. While retaining the lifting frame 12, transmission cavity 122, limiting structure, sliding structure 123, snap-fit ​​structure 124, and worm gear 1251-worm wheel 1252 drive mechanism from Embodiment 1, this embodiment adds a moving roller 128, a stabilizing arm 129, a limiting seat 132 and grid plate 133, and a lifting platform 14, further enhancing the functionality and safety of the equipment. It is suitable for applications in building decoration, equipment maintenance, and high-altitude work.

[0036] The aluminum alloy lifting platform 1 in this embodiment includes a base 11, a lifting frame 12 fixed on the base 11, and an operating platform 13 fixed to the top of the lifting frame 12. The base 11 is made of high-strength aluminum alloy and has a rectangular frame structure to ensure sufficient rigidity and load-bearing capacity. The upper surface of the base 11 is used to fix the lifting frame 12, and the interior space is reserved to accommodate the lifting drive mechanism 125. The operating platform 13 is made of aluminum alloy sheet with anti-slip texture on the surface and guardrails installed around it to ensure the safety of the operator.

[0037] The lifting frame 12 consists of two sets of parallel lifting frames 12, fixed to the left and right sides of the base 11 respectively. Each set of lifting frames 12 includes three longitudinally telescopically connected lifting rods 112, namely the bottom lifting rod 112, the middle lifting rod 112, and the top lifting rod 112. The lifting rods 112 are made of high-strength hollow aluminum alloy profiles with a rectangular cross-section. Each section of the lifting rod 112 has a longitudinally extending transmission cavity 122 for accommodating the lifting drive components 1253, including wire ropes and pulley blocks. The inner walls of the lifting rods 112 below the top (bottom lifting rod 112 and middle lifting rod 112) are provided with limiting structures, including limiting bosses and limiting grooves. The bosses are evenly spaced longitudinally, and the grooves are adapted to the bosses on the outer walls of adjacent lifting rods 112 to limit the extension stroke and prevent the stroke from exceeding the limit or the structure from becoming unstable.

[0038] Each section of the lifting rod 112 has a sliding structure 123 and a snap-fit ​​structure 124 on its side wall. The snap-fit ​​structure 124 consists of two sets of vertical limiting grooves 126 on the outer wall of the lifting rod 112, extending longitudinally along the lifting rod 112. The sliding structure 123 consists of limiting sliders 127 adapted to the limiting grooves 126, made of high-strength nylon material, fixed to the inner wall of adjacent lifting rods 112, and embedded in the limiting grooves 126 to achieve a sliding connection, ensuring stability during the extension and retraction process. The top lifting rods 112 of the two sets of lifting frames 12 are connected by an operating platform 13, which is fixed to the top lifting rods 112 by bolts or welding. The connection is reinforced with ribs to enhance torsional resistance. The bottom lifting rods 112 are fixed to the base 11 by bolts to ensure the stability of the overall structure.

[0039] The lifting drive mechanism 125 is located inside the base 11 and includes a worm gear 1251 and a worm wheel 1252 meshing with the worm gear 1251. The worm gear 1251 is made of high-strength steel and is fixed in the drive cavity of the base 11 by bearings, and is connected to a DC servo motor. The worm wheel is connected to a wire rope and a pulley block, and the extension and retraction of the lifting rod 112 is realized by the motor drive, so as to precisely control the lifting height and speed of the operating platform 13.

[0040] To improve the mobility and stability of the equipment, this embodiment features casters 128 installed at both ends of the bottom of the base 11. The casters are made of high-strength polyurethane material and have a locking function to ensure the equipment can be fixed in position after movement. Four stabilizing arms 129 are rotatably mounted on the side of the base 11. The stabilizing arms 129 are made of aluminum alloy tubing and connected to the base 11 via hinges, allowing them to rotate freely to a horizontal or vertical position. The distal end of each stabilizing arm 129 has a retractable support rod 131. The support rod 131 is a steel telescopic rod with a rubber pad at the end to increase friction with the ground. When the stabilizing arm 129 is lowered, the support rod 131 extends and contacts the ground, forming an additional support point, effectively distributing the equipment's center of gravity, improving stability during high-altitude operations, and preventing tipping.

[0041] An integrated limit seat 132 is provided on the side of the operating table 13. The limit seat 132 is an aluminum alloy casting and is integrally formed with the operating table 13. The limit seat 132 has a snap-fit ​​groove for installing a detachable grid plate 133. The grid plate 133 is made of aluminum alloy with a grid-like surface to reduce weight while maintaining strength. The grid plate 133 has two limit rods made of steel, which can be inserted into the snap-fit ​​groove of the limit seat 132 and fixed with nuts. The detachable design of the grid plate 133 facilitates installation and maintenance, while providing additional safety protection to prevent operators or tools from slipping off the side of the operating table 13.

[0042] Furthermore, the lifting platform in this embodiment includes a lift 14 connected to the operating platform 13 for convenient access for operators. The lift 14 is made of aluminum alloy, and its total height is adjustable according to the height of the operating platform 13. The lift 14 is hinged to the side of the operating platform 13, can be folded for storage, and is secured with latches when unfolded to ensure safe use. The lift 14 improves the operator's access efficiency, making it particularly suitable for scenarios involving frequent high-altitude operations.

[0043] In actual use, the operator pushes the elevator to the working position using the moving rollers 128, lowers the stabilizing arm 129, and adjusts the support rod 131 to contact the ground to ensure the equipment is stable. The motor is started, and the worm gear 1251-worm wheel 1252 mechanism drives the wire rope and pulley block, causing the two sets of lifting frames 12 to extend and retract synchronously, and the operating platform 13 is smoothly raised to the designated height. The cooperation between the limit slider 127 and the limit groove 126 ensures the stable sliding of the lifting rod 112, and the limit boss and groove limit the extension and retraction stroke to prevent exceeding the limit. The operator climbs onto the operating platform 13 via the elevator 14, installs the grid plate 133 to enhance side protection, and completes the high-altitude work task.

[0044] The aluminum alloy lifting platform 1 in this embodiment enhances the stability of the overall structure through the design of two sets of parallel lifting frames 12; the installation of moving rollers 128 and stabilizing arms 129 improves the mobility and safety of the equipment; the cooperation between the limiting seat 132 and the grid plate 133, as well as the addition of the lifting ladder 14, improves the convenience and safety of operation. Compared with Embodiment 1, this embodiment further optimizes functionality and applicability, meets the needs of complex high-altitude operations, and has higher practical value and market competitiveness.
