Description

Technical Field

[0001] The invention relates to the technical field of wind power tower construction, in particular to an adjustable concrete wind power tower hoisting construction platform. Background Art

[0002] With the growing global demand for clean energy, wind power generation has been widely adopted and developed as a sustainable energy solution. In wind power generation systems, towers, as the key structure supporting wind turbines, are constantly increasing in height and size. In inland areas, in particular, where wind speeds are relatively low, increasing tower height is necessary to improve power generation efficiency and capture greater wind energy resources. Concrete wind turbine towers are increasingly used in the wind power sector due to their high rigidity, good durability, and low cost. Concrete towers are generally prefabricated in sections and pieces, then transported to the site for assembly and hoisting. After each concrete section is hoisted, a series of follow-up tasks are required, such as removing the hooks at the top of the section, measuring the levelness of the top surface, placing steel shims, and applying epoxy structural adhesive. These tasks require construction workers to perform on a safe, stable, and easy-to-operate construction platform.

[0003] However, the existing adjustable concrete wind tower hoisting construction platform still has certain defects when in use; 1. Existing concrete wind turbine tower hoisting construction platforms mostly use fixed structures and lack flexible adjustment functions. This makes the platform only suitable for hoisting wind turbine towers of specific sizes and types. When faced with wind turbine towers of different specifications, the size and position cannot be adjusted, resulting in poor applicability. At the same time, the operation process is relatively cumbersome, and the assembly and disassembly stages require a lot of time and effort. There is also no flexibility in the hoisting process, resulting in low construction efficiency. 2. Existing construction platforms have significant safety deficiencies. For one thing, inadequate protective measures, crude guardrails, and blind spots make it easy for construction workers to fall while working at height. Furthermore, the platforms lack stability and are prone to shaking or even capsizing when subjected to external forces. This poses a serious threat to the safety of construction workers and equipment, particularly in inclement weather or when hoisting large components.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the emergence of this case.

[0005] In response to the above problems, an innovative design was carried out based on the original adjustable concrete wind tower hoisting construction platform. Summary of the Invention

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: an adjustable concrete wind tower hoisting construction platform, comprising a first connecting seat and a second connecting seat; The outer ring of the connecting seat is fixedly installed with a square tube sleeve 1 at equal angles, and the inner supporting square tube and the outer supporting square tube are connected between the square tube sleeves 1. The outer ring of the connecting seat is symmetrically installed with a square tube sleeve 2, and the inner connecting square tube and the outer connecting square tube are fixedly installed on both sides of the square tube sleeve 2. The inner connecting square tube and the outer connecting square tube at the rear end are fixedly connected to the square tube sleeve 1 at the front side through a connecting plate; The interior of the square tube sleeve 1 and the square tube sleeve 2 are both provided with a telescopic beam assembly 1; The connecting seat 1 is provided with a telescopic transmission assembly, and the telescopic transmission assembly is transmitted to the telescopic beam assembly 1; A fixing frame is fixedly installed on the top of the inner connecting square tube and the outer connecting square tube on the front side, and a telescopic beam assembly 2 is arranged inside the fixing frame; A pedal assembly is installed on the top surface of the telescopic beam assembly 1 and the telescopic beam assembly 2; The outer rings of the telescopic beam assembly 1 and the telescopic beam assembly 2 are connected with a protective assembly.

[0008] Preferably, the rear end of the fixing frame is fixedly connected to the square tube sleeve 1 on the front side through a connecting plate, and the outer end top surfaces of the square tube sleeve 1, square tube sleeve 2 and the fixing frame are all fixedly installed with side pull rings.

[0009] The above technical solution provides a stable support foundation for the entire hoisting construction platform through the connection base 1 and the connection base 2 and the square tube sleeve 1 and square tube sleeve 2 structures thereon. At the same time, the arrangement of the telescopic beam assembly 1, the telescopic transmission assembly, the telescopic beam assembly 2, etc. enables the platform to flexibly adjust its size and position according to the actual hoisting construction requirements, thereby improving the applicability and flexibility of the construction platform. The pedal assembly and the protective assembly provide a safe and reliable working environment for the construction workers. The rear end of the fixed frame is connected to the square tube sleeve through a connecting plate, which enhances the stability of the structure. The setting of the side pull ring facilitates auxiliary pulling through external force during the lifting process, further ensuring the stability and safety of the construction platform during the lifting process.

[0010] Preferably, the telescopic beam assembly includes a movable square tube 1 that is slidably installed inside the square tube sleeve 1 and the square tube sleeve 2. The tops of the square tube sleeve 1 and the square tube sleeve 2 are both provided with a limiting groove 1. The internal sliding connection of the limiting groove 1 is connected to a limiting pin 1. The bottom end of the limiting pin 1 is fixedly connected to the movable square tube 1. The movable square tube 1 forms a limiting sliding structure through the limiting pin 1 and the limiting groove 1.

[0011] Preferably, the telescopic beam assembly also includes a transmission seat fixedly mounted on the bottom of the movable square tube, the internal thread of the transmission seat is penetrated by an adjusting screw, both ends of the adjusting screw are rotatably sleeved with positioning shaft seats, and the inner end of the adjusting screw is fixedly mounted with a driven bevel gear.

[0012] Preferably, the square tube sleeve 1 and the square tube sleeve 2 are slidably connected to the transmission seat corresponding to the bottom, and the square tube sleeve 1 and the square tube sleeve 2 are fixedly connected to the top of the positioning shaft seat corresponding to the bottom.

[0013] By adopting the above technical solution, the movable square tube 1 can slide inside the square tube sleeve 1 and the square tube sleeve 2, and the cooperation between the limit pin 1 and the limit groove 1 limits the sliding of the movable square tube 1, making the telescopic action of the telescopic beam assembly 1 more stable and reliable, avoiding shaking or deviation during the telescopic process, thereby ensuring the stability of the overall structure of the construction platform; The arrangement of the transmission seat, the adjusting screw, the positioning shaft seat and the driven bevel gear provides an effective transmission mechanism for the telescopic movement of the telescopic beam assembly 1. By rotating the adjusting screw, the movable square tube 1 can be driven to perform telescopic movement, thereby achieving flexible adjustment of the size of the construction platform. At the same time, the driven bevel gear is engaged with the subsequent telescopic transmission assembly, so that the entire telescopic movement can be driven by an external power source, making the operation more convenient and efficient. At the same time, the square tube sleeves 1 and 2 can work stably with the transmission seat and the positioning shaft seat, ensuring the smoothness and stability of the telescopic beam assembly 1 during the telescopic process, while also facilitating the assembly and disassembly of the entire structure and improving the maintainability and operability of the construction platform.

[0014] Preferably, the telescopic transmission assembly includes a fixed shaft seat fixedly mounted on an inner ring of a connecting seat, the inner ring of the fixed shaft seat is fixedly connected to a connecting rod, the bottom end of the connecting rod is fixedly mounted with a driving bevel gear, and the driving bevel gear is vertically meshed with the driven bevel gear.

[0015] Preferably, the telescopic transmission assembly also includes a worm wheel fixedly mounted on the top end of the connecting rod, the outer side of the worm wheel is meshingly connected to a worm, one end of the worm is rotatably sleeved on a limiting shaft seat, the bottom end of the limiting shaft seat is fixedly connected to the top surface of the connecting seat, the other end of the worm is connected to a servo motor through a coupling, and the bottom of the servo motor is fixedly connected to the top surface of the connecting seat.

[0016] With the above technical solution, the fixed shaft seat, connecting rod, active bevel gear and driven bevel gear are vertically meshed and connected to form an effective power transmission system. The connecting rod is driven to rotate by an external power source, thereby driving the active bevel gear to rotate. The active bevel gear then transmits power to the driven bevel gear through meshing, thereby realizing the control of the telescopic movement of the telescopic beam assembly 1. This transmission method has the advantages of compact structure, high transmission efficiency and accurate transmission ratio. It can accurately control the telescopic length of the telescopic beam assembly 1 and meet the size adjustment requirements in different lifting construction scenarios. The addition of the worm gear transmission gives the telescopic transmission assembly a self-locking function. When the servo motor stops working, the telescopic beam assembly can stably maintain the current telescopic position and will not accidentally extend or retract due to external forces, thereby improving the safety and reliability of the construction platform. At the same time, the use of the servo motor can achieve precise control and automated operation of the telescopic action, further improving construction efficiency and quality.

[0017] Preferably, the telescopic beam assembly two includes a movable square tube two symmetrically slidably installed inside the fixed frame, a limiting groove two is provided on the top of both ends of the fixed frame, a limiting pin two is slidably installed inside the limiting groove two, the bottom end of the limiting pin two is fixedly connected to the movable square tube two, positioning grooves are provided at equal intervals on both sides of the top surface of the movable square tube two, and positioning pins are symmetrically passed through the front ends of both sides of the fixed frame, and the positioning pins are engaged with the movable square tube two through the positioning grooves.

[0018] By adopting the above technical solution, the symmetrical sliding installation of the movable square tube 2 inside the fixed frame, and the cooperation of the limit groove 2, the limit pin 2, the positioning groove and the positioning pin, the telescopic beam assembly 2 can also achieve flexible telescopic adjustment, and after adjusting to the appropriate position, it can be fixed by the engagement of the positioning pin and the positioning groove, thereby meeting the diverse requirements of the construction platform size in different lifting construction scenarios, and further improving the applicability and flexibility of the construction platform.

[0019] Preferably, the outer ends of the movable square tube one and the movable square tube two are both installed with fixed angle plates, the top of the movable square tube one which is slidably connected inside the square tube sleeve two is fitted with a connecting angle plate, the top surfaces of the connecting angle plate, the movable square tube one and the movable square tube two are installed with a pedal assembly, the pedal assembly includes a movable pedal movably installed on the top surfaces of the connecting angle plate, the movable square tube one and the movable square tube two, the connecting angle plate is fixedly connected to the movable pedal corresponding to the top, pull rods are installed on the top surfaces of both ends of the movable pedal, oblong holes are opened at both ends of the movable pedal and the interior of the connecting angle plate, a pin is movably passed through the interior of the oblong hole, and the movable square tube one and the movable square tube two are movably plugged with the pin corresponding to the top.

[0020] By adopting the above technical solution, the coordination of the movable pedal, pull rod, oblong hole and pin allows the pedal assembly to be flexibly adjusted and fixed according to actual construction needs. The pin passes through the oblong hole and is fixed with the movable square tube one and movable square tube two for movable connection, so that the movable pedal can slide on the pin using the oblong hole during telescopic adjustment, which is beneficial to provide radial position adjustment for the movable pedal.

[0021] Preferably, the protection assembly includes multiple groups of guardrail posts, the guardrail posts arranged in a ring shape on the outer circle are fixedly connected to the fixed angle plates, the guardrail posts symmetrically distributed on the inner side are fixedly connected to the fixing frame, and chains are fixedly connected between the guardrail posts.

[0022] By adopting the above technical solution, the setting of the protective components provides all-round safety protection for construction workers. The fixed connection between the guardrail posts and the fixed angle plates and fixed frames, as well as the connection of the chains, form a solid protective barrier, which effectively prevents construction workers from accidentally falling during the operation, ensures the personal safety of construction workers, and also provides strong protection for the overall safety of the construction platform.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the adjustable concrete wind tower hoisting construction platform, through the carefully designed connecting seat, square tube sleeve, telescopic beam assembly, telescopic transmission assembly, pedal assembly and protective assembly and other structures, realizes the flexible adjustment of the construction platform size and position, meets the diverse needs under different hoisting construction scenarios, and its structure is stable and reliable, which can effectively ensure the safety and stability during the construction process. At the same time, it is easy and efficient to operate, significantly improving the construction efficiency and construction quality, and providing an efficient, safe and reliable solution for the hoisting construction of wind towers. The specific contents are as follows: 1. Connecting Base 1 and 2, and their outer rings of Square Tube Sleeves 1 and 2, provide a stable support foundation for the entire construction platform. The inner and outer connecting square tubes at the rear end are fixedly connected to Square Tube Sleeve 1 at the front via connecting plates, enhancing the overall structural stability of the platform and ensuring it can withstand heavy loads without deformation or damage during hoisting. This stable support structure is a prerequisite for subsequent telescopic adjustment and hoisting construction. 2. The design of telescopic beam assembly 1 provides excellent adjustability in the platform's length. The sliding movement of movable square tube 1 within square tube sleeves 1 and 2, as well as the limited cooperation between limit pin 1 and limit slot 1, ensure the stability and reliability of the telescopic movement. The transmission mechanism consisting of the drive seat, adjustment screw, positioning shaft seat, and driven bevel gear allows the telescopic movement to be precisely controlled by an external power source, achieving flexible adjustment of the platform size to meet the length requirements of different lifting construction scenarios. The design of the telescopic beam assembly further enhances the width adjustability of the construction platform. The symmetrical sliding installation of the movable square tube assembly within the fixed frame, along with the coordinated positioning of the second limit slot, the second limit pin, the positioning slot, and the positioning pin, allows the platform to be flexibly adjusted in width to meet actual construction needs. This design not only improves the applicability and flexibility of the construction platform, but also better adapts to the requirements of different wind turbine tower structures and hoisting construction techniques.

[0024] 3. The telescopic transmission assembly provides effective power transmission and control for the telescopic beam assembly's telescopic movement. The fixed shaft seat, connecting rod, and vertical meshing of the driving and driven bevel gears ensure efficient power transmission and precise control. The addition of a worm gear drive not only further improves transmission efficiency but also provides a self-locking function for the telescopic transmission assembly, ensuring that the telescopic beam assembly remains stably in its current position after being extended and retracted, preventing accidental extension and retraction due to external forces. This improves the safety and reliability of the construction platform. The use of a servo motor automates and precisely controls the telescopic movement, enhancing both construction efficiency and quality.

[0025] 4. The flexible design of the pedal assembly provides a comfortable and convenient working platform for construction workers. The combination of the movable pedal, pull rod, oblong hole, and latch allows construction workers to freely adjust the position of the movable pedal according to their work habits and comfort requirements, and the pull rod and latch firmly secure it. This adjustable pedal design not only improves construction workers' working comfort but also effectively reduces fatigue during long work periods, thereby improving construction efficiency and quality.

[0026] 5. The protective components provide comprehensive safety protection for construction workers. The fixed connections between multiple guardrail posts, fixed angle plates, and fixed brackets, as well as the chain connections between the guardrail posts, form a solid protective barrier, effectively preventing construction workers from accidentally falling during operations. This safety measure not only ensures the personal safety of construction workers but also provides strong security for the entire lifting construction process, allowing construction workers to work with greater peace of mind and further improving the safety and reliability of the construction.

The telescopic beam assembly 1 also includes a transmission seat 16 fixedly installed at the bottom of the movable square tube 12, the square tube sleeve 13 and the square tube sleeve 26 are connected with the transmission seat 16 corresponding to the bottom through sliding connection, the internal thread of the transmission seat 16 is penetrated by an adjusting screw 17, and the two ends of the adjusting screw 17 are rotatably sleeved with a positioning shaft seat 18, the square tube sleeve 13 and the square tube sleeve 26 are fixedly connected to the top of the positioning shaft seat 18 corresponding to the bottom, and the inner end of the adjusting screw 17 is fixedly installed with a driven bevel gear 19; The above-mentioned structural design, in the hoisting construction platform of the adjustable concrete wind turbine tower of the present invention, the connecting seat 1 and the connecting seat 2 2 constitute the basic support structure of the platform, the outer ring of the connecting seat 1 is fixedly installed with a square tube sleeve 3 at equal angles, and these square tube sleeves 3 are connected to each other through the inner supporting square tube 4 and the outer supporting square tube 5 to form a stable support frame, the outer ring of the connecting seat 2 is symmetrically installed with a square tube sleeve 2 6, and the two sides of the square tube sleeve 2 6 are respectively fixedly installed with an inner connecting square tube 7 and an outer connecting square tube 8, the inner connecting square tube 7 and the outer connecting square tube 8 at the rear end are fixedly connected to the square tube sleeve 3 on the front side through the connecting plate 9, further enhancing the stability of the entire platform structure, the rear end of the fixing frame 10 is also fixedly connected to the square tube sleeve 3 on the front side through the connecting plate 9, and the square tube sleeve 3, the square tube sleeve 2 6 and the outer ring top surface of the fixing frame 10 are all fixedly installed with side pull rings 11, which can be used for auxiliary pulling by external force during the hoisting process to ensure the stability and safety of the platform during the hoisting process; A telescopic beam assembly 1 is provided inside the square tube sleeve 1 3 and the square tube sleeve 2 6. The core component of the telescopic beam assembly 1 is the movable square tube 12, which is slidably installed inside the square tube sleeve 1 3 and the square tube sleeve 2 6. The setting of the limiting groove 14 and the limiting pin 15 enables the movable square tube 12 to slide inside the square tube sleeve 1 3 and the square tube sleeve 2 6. At the same time, the cooperation of the limiting pin 15 and the limiting groove 14 limits the sliding of the movable square tube 12, ensuring the stability and reliability of the telescopic action, avoiding shaking or deviation during the telescopic process, and thus ensuring the stability of the overall structure of the construction platform; When the telescopic beam assembly 1 needs to be telescopically adjusted, the active bevel gear 22 meshing with the driven bevel gear 19 is driven by an external power source. The rotation of the active bevel gear 22 drives the driven bevel gear 19 to rotate, thereby causing the adjusting screw 17 to rotate in the transmission seat 16. Since the adjusting screw 17 and the transmission seat 16 are threadedly connected, the rotation of the adjusting screw 17 will be converted into a linear motion of the movable square tube 12 inside the square tube sleeve 1 3 and the square tube sleeve 2 6, thereby realizing the telescopic action of the movable square tube 12. This transmission mechanism allows the telescopic action to be precisely controlled by an external power source, thereby realizing flexible adjustment of the construction platform size, and making the operation more convenient and efficient.

[0031] A telescopic transmission assembly is provided on the connecting seat 1, and the telescopic transmission assembly is transmitted to the telescopic beam assembly 1. The telescopic transmission assembly includes a fixed shaft seat 20 fixedly mounted on the inner ring of the connecting seat 1, and the inner ring of the fixed shaft seat 20 is fixedly connected to a connecting rod 21. The bottom end of the connecting rod 21 is fixedly mounted with a driving bevel gear 22, and the driving bevel gear 22 is vertically meshed with the driven bevel gear 19. The telescopic transmission assembly also includes a worm gear 23 fixedly mounted on the top of the connecting rod 21, and the outer side of the worm gear 23 is meshed with a worm 24. One end of the worm 24 is rotatably sleeved on a limiting shaft seat 25, and the bottom end of the limiting shaft seat 25 is fixedly connected to the top surface of the connecting seat 1. The other end of the worm 24 is connected to a servo motor 26 through a coupling, and the bottom of the servo motor 26 is fixedly connected to the top surface of the connecting seat 1; With the above-described structural design, when servo motor 26 is powered on, its output shaft drives worm 24 to rotate about its own axis through a coupling. One end of worm 24 is supported by a limited shaft seat 25, ensuring its rotational stability. The rotating worm 24 engages with worm wheel 23 through threads, converting horizontal rotational motion into vertical rotational motion. Because the worm 24-worm wheel 23 transmission has a self-locking characteristic, when servo motor 26 stops, worm wheel 23 cannot reverse drive worm 24, thereby locking the current position. The worm gear 23 is fixedly connected to the connecting rod 21, so the rotation of the worm gear 23 drives the connecting rod 21 to rotate synchronously around the axis of the fixed shaft seat 20. The fixed shaft seat 20 is rigidly connected to the connecting seat 1 by bolts, providing stable support for the entire transmission system. The active bevel gear 22 at the bottom end of the connecting rod 21 rotates therewith and realizes vertical meshing with multiple driven bevel gears 19. Since the driven bevel gears 19 are respectively fixed to the inner ends of the adjusting screws 17, the rotation of the active bevel gear 22 drives all the adjusting screws 17 to rotate synchronously at the same time, and the adjusting screws 17 are rotated synchronously. The rotation of the segmented screw 17 drives the transmission seat 16 to move along the axial direction of the screw through the thread. Since the transmission seat 16 is fixedly connected to the movable square tube 12, and the movable square tube 12 limits the rotational freedom through the limit pin 15 and the limit groove 14, the rotational motion of the screw is finally converted into the linear telescopic motion of the movable square tube 12. When the servo motor 26 rotates clockwise, the adjusting screw 17 drives the movable square tube 12 to extend outward, and the platform diameter increases; when it rotates counterclockwise, the movable square tube 12 retracts inward, and the platform diameter decreases.

[0032] A fixing frame 10 is fixedly installed on the top of the front inner connecting square tube 7 and the outer connecting square tube 8. A telescopic beam assembly 2 is provided inside the fixing frame 10. The telescopic beam assembly 2 includes a movable square tube 27 symmetrically slidably installed inside the fixing frame 10. A limiting groove 28 is provided on the top of both ends of the fixing frame 10. A limiting pin 29 is slidably installed inside the limiting groove 28. The bottom end of the limiting pin 29 is fixedly connected to the movable square tube 27. Positioning grooves 30 are provided on both sides of the top surface of the movable square tube 27 at equal intervals. Positioning pins 31 are symmetrically penetrated by the front ends of both sides of the fixing frame 10. The positioning pins 31 are engaged with the movable square tube 27 through the positioning grooves 30. With the above-mentioned structure, when the lateral working range of the construction platform needs to be expanded, the positioning pin 31 is first pulled out from the engagement state between the fixing frame 10 and the positioning groove 30 on the top surface of the movable square tube 27, thereby releasing the position restriction of the movable square tube 27. At this time, due to the cooperation between the limiting pin 29 and the limiting groove 28, the movable square tube 27 is restricted to sliding linearly along the interior of the fixing frame 10, thereby preventing deviation or rotation during the sliding process. The locating pin 31 is then inserted into the positioning groove 30 to lock the movable square tube 27 in the current extended position, thereby preventing it from being displaced by external forces during construction. When the platform needs to be retracted, the locating pin 31 is pulled out again, and the movable square tube 27 is slid back along the fixed frame 10 in the opposite direction until it returns to its initial position. The locating pin 31 is then inserted to fix it, completing the adjustment process of the horizontal size of the platform. The entire process is guided by the limiting pin 29 and the limiting groove 28 and locked by the locating pin 31 and the positioning groove 30, thereby realizing convenient and reliable telescopic adjustment and position fixing of the telescopic beam assembly 2.

[0033] The outer ends of the movable square tube 12 and the movable square tube 2 are both installed with fixed angle plates 13, and the top of the movable square tube 12 slidably connected inside the square tube sleeve 26 is fitted with a connecting angle plate 38. The top surfaces of the connecting angle plate 38, the movable square tube 12 and the movable square tube 2 are installed with a pedal assembly. The pedal assembly includes a movable pedal 32 movably installed on the connecting angle plate 38, the movable square tube 12 and the top surface of the movable square tube 2, the connecting angle plate 38 is fixedly connected to the movable pedal 32 corresponding to the top, and pull rods 33 are installed on the top surfaces of both ends of the movable pedal 32. Long circular holes 34 are opened at both ends of the movable pedal 32 and the interior of the connecting angle plate 38. A latch 35 movably penetrates the interior of the long circular hole 34, and the movable square tube 12 and the movable square tube 2 are movably plugged with the latch 35 corresponding to the top; The above structure is designed so that before installing the movable pedal 32, the movable pedal 32 is first placed on the top surface of the connecting angle plate 38, the movable square tube 1 12 and the movable square tube 2 27, wherein the connecting angle plate 38 is fixedly connected to the movable pedal 32 that is in contact with the top, and an oblong hole 34 corresponding to the movable pedal 32 is opened inside the connecting angle plate 38, ensuring that the oblong holes 34 at both ends of the movable pedal 32 are docked with the slots opened inside the movable square tube 1 12 and the movable square tube 2 27, then the pin 35 is passed through the oblong holes 34 at both ends of the movable pedal 32 and inserted into the corresponding jacks of the movable square tube 1 12 or the movable square tube 2 27 below, thereby achieving a fixed connection between the movable pedal 32 and the supporting structure below; The design of the oblong hole 34 has a dual function: first, when the pin 35 is inserted, a certain installation error tolerance is allowed between the movable pedal 32 and the supporting structure, thereby reducing the difficulty of installation; second, when the movable square tube 1 12 of the telescopic beam assembly 1 and the movable square tube 2 27 of the telescopic beam assembly 2 are telescopically adjusted, the movable pedal 32 can slide with the telescopic adjustment, so as to facilitate the reduction and expansion of the distance between the movable pedals 32, ensuring that the movable pedal 32 will not fall off or shift during the telescopic process. If the movable pedal 32 needs to be disassembled, the operator only needs to pull the pin 35 and unplug the pin 35 from the oblong hole 34 and the socket of the supporting structure below to easily remove the movable pedal 32, which is convenient for inspection and replacement of the pedal, or reduces space occupancy during platform transportation and storage.

[0034] The outer rings of the telescopic beam assembly 1 and the telescopic beam assembly 2 are connected to a protection assembly, which includes multiple groups of guardrail posts 36. The guardrail posts 36 arranged in an annular shape on the outer ring are fixedly connected to the fixed angle plate 13, and the guardrail posts 36 symmetrically distributed on the inner side are fixedly connected to the fixed frame 10. Chains 37 are fixedly connected between the guardrail posts 36; The above-mentioned structural design achieves safety protection through the linkage design of the protective assembly and the telescopic beam assembly. The outer guardrail posts 36 are connected to the fixed angle plates 13 at the outer ends of the movable square tubes 12 and 27, while the inner guardrail posts 36 are fixed to the fixed frame 10. When the telescopic beam assemblies 1 and 2 are adjusted, the outer guardrail posts 36 move synchronously with the movable square tubes 12 and 27, while the inner guardrail posts 36 remain fixed. The chains 37 between the guardrail posts 36 remain tensioned during the movement of the posts, forming a continuous protective barrier that effectively prevents people and tools from falling and cushions collisions through its flexible structure. At the same time, the structure can automatically adjust the protection range according to the extension and contraction of the platform, without the need for additional disassembly or installation, ensuring the integrity and convenience of the protective function during construction.
