[0030] In a further preferred embodiment of the present invention, a plurality of anti-skid plates 21 are installed on the inner wall of the protection frame 5 , and the plurality of anti-skid plates 21 are in contact with the plurality of baffles 7 respectively.

[0031] In this embodiment, the anti-skid plate 21 provides an anti-slip surface, increases the friction between the baffle 7 and the inner wall of the protective frame 5, and prevents the baffle 7 from sliding or falling off when subjected to external force. The presence of the anti-skid plate 21 significantly reduces the risk of accidental sliding of the baffle 7, thereby avoiding safety accidents that may be caused by the baffle 7 falling off. By increasing the friction, the anti-skid plate 21 helps fix the position of the baffle 7, making it more stably attached to the protective frame 5, thereby improving the stability of the overall structure.

[0032] In a further preferred embodiment of the present invention, a mounting rod 12 is installed on one side of the plurality of pedals 4 close to the guide rail 1, and a plurality of support members 13 are installed on the mounting rod 12, and the plurality of support members 13 can all contact with the building surface, and the tops of the plurality of pedals 4 are provided with anti-slip grooves, and the plurality of pedals 4 are provided with drainage holes.

The support member 13 further improves the stability and safety of the pedal 4, ensuring the safety of construction workers working in complex environments. By increasing the roughness of the surface of the pedal 4, the friction between the soles of the construction workers' feet and the pedal 4 is increased, preventing slipping accidents in wet or oily conditions, significantly improving the safety of the use of the pedal 4, and reducing the risk of injury to construction workers due to slipping during operation. The drainage hole allows liquids such as accumulated water or rainwater on the pedal 4 to be quickly discharged, preventing problems such as slipping or corrosion caused by water accumulation on the surface of the pedal 4.

[0034] In a further preferred embodiment of the present invention, the support member 13 is composed of a mounting bar 14, a plurality of rotating shafts 15, and a plurality of extension rods 16. The mounting bar 14 is fixed to the top of the mounting rod 12, and the plurality of rotating shafts 15 are rotatably mounted on the mounting bar 14. The plurality of extension rods 16 are respectively fixed on the plurality of rotating shafts 15, and the spacing between the plurality of extension rods 16 is not less than 3 cm.

[0035] In this embodiment, the mounting strip 14 serves as the basic structure of the support member 13 and provides a mounting position for the rotating shaft 15, thereby ensuring that the entire support member 13 can be firmly connected to the pedal 4, thereby enhancing the connection strength between the support member 13 and the pedal 4, and enabling the support member 13 to more effectively bear the load from the construction workers. The rotating shaft 15 allows the extension rod 16 to rotate around it, thereby adjusting the contact angle and position of the extension rod 16 with the building surface to adapt to building structures of different shapes and inclinations, thereby improving the adaptability and flexibility of the support member 13, and enabling the pedal 4 to remain stable in a wider range of construction environments. The extension rod 16, as a component that directly contacts the building surface, transfers the weight of the pedal 4 and the load of the construction workers to the building structure through its supporting function. At the same time, the spacing design of multiple extension rods 16 helps to disperse the pressure and improve the supporting effect. The smaller spacing can also prevent falling from heights.

[0036] In a further preferred embodiment of the present invention, the extension rod 16 is composed of a threaded barrel, a threaded rod and an adjustment block, the threaded barrel is fixed on any one of the rotating shafts 15, the threaded rod is threadedly installed in the threaded barrel, and the adjustment block is fixed on the threaded rod.

[0037] In this embodiment, the threaded barrel serves as the installation base of the threaded rod, and provides an internal thread to cooperate with the threaded rod to achieve the adjustment of the length of the extension rod 16. Through the threaded cooperation, the threaded barrel ensures that the threaded rod can move smoothly along the axial direction during rotation, thereby adjusting the length of the extension rod 16. The adjustment block is the part of the extension rod 16 that is in direct contact with the building surface. Through its shape and material design, it enhances the friction and stability with the building surface. At the same time, the adjustment block also provides a grip point when rotating the threaded rod.

[0038] In a further preferred embodiment of the present invention, at least two support rods 11 are fixed to the bottom of each of the pedals 4, each of the support rods 11 is connected to the protective frame 5, and the chain 17 is provided with an anti-corrosion coating.

[0039] In this embodiment, the support rod 11 serves as a connecting component between the pedal 4 and the protective frame 5, and is mainly responsible for transferring the weight of the pedal 4 and the load of the construction workers to the protective frame 5, thereby enhancing the stability of the pedal 4. By setting at least two support rods 11, the pressure of the pedal 4 on the protective frame 5 is dispersed, and the stability of the overall structure is improved. At the same time, the support rod 11 also increases the anti-overturning ability of the pedal 4 when it is moving or subjected to external forces, thereby ensuring the safety of the construction workers. The anti-corrosion coating can effectively isolate the chain 17 from direct contact with the external environment to prevent it from being damaged by corrosion, rust, etc., which not only extends the service life of the chain 17, but also ensures its stability and reliability during use. At the same time, it also reduces the safety hazards and maintenance costs caused by damage to the chain 17.

[0040] To sum up, compared with the related art, the present device can adjust the height of the movable frame 2 by setting an adjustment component, so that the height of the climbing frame can be adjusted according to construction needs. By setting the guide rail 1, a guide can be provided for the ascent and descent of the climbing frame, thereby increasing the stability of the movement of the climbing frame. By setting the support member 13, the distance between the climbing frame and the building can be closed. By adjusting the length and angle of the extension rod 16, the support member 13 can be in contact with the building surface with low flatness, thereby ensuring the protective effect and preventing objects or people from falling.
