[0024] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, including a plurality of step units 1 connected in sequence, adjacent step units 1 are inclined and distributed along the vertical direction, the step unit 1 includes a connecting seat 2, there are a plurality of connecting seats 2, and a plurality of connecting seats 2 are distributed along a linear direction, the pedal 3 is movably arranged on the connecting seat 2, and the sliding direction of the pedal 3 is orthogonal to the distribution direction of the connecting seat 2, there are a plurality of connecting members 4, and the connecting member 4 is used to connect the connecting seat 2 and the pedal 3.

[0025] In the present disclosure, a plurality of ladder units 1 are connected in sequence to form a walkway ladder. In each ladder unit 1, a pedal 3 is movably arranged on a connection seat 2 distributed along a linear direction, and the connection seats 2 and pedals 3 of adjacent ladder units 1 are connected to each other through a connector 4. During installation and use, the position of the pedal 3 on the connection seat 2 can be adjusted according to actual needs to adapt to different site conditions and use requirements. The use of SMC composite materials makes the walkway ladder lightweight, easy to transport and install, and reduces labor costs and construction difficulties. Good corrosion resistance, not easy to rust and corrode in a humid environment, prolonging service life and improving safety. The assembled structure can flexibly adapt to different site and space requirements, especially in complex construction environments or places with limited space. The movable design of the pedal 3 on the connection seat 2 increases the adjustability and applicability of the walkway ladder. The overall structure is stable and can provide a reliable climbing channel to ensure the safety of users. This SMC composite assembled walkway ladder can be widely used in the following scenarios: construction sites, providing workers with safe and convenient climbing channels. In industrial plants, it is used for climbing operations during equipment maintenance and operation. Municipal road maintenance or street light maintenance projects. Various temporary venues for activities, such as exhibition venues, music festivals, etc.

[0026] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, the lower end of the connecting seat 2 is connected to the pedal 3 of the adjacent step unit 1; the pedal 3 has a first sliding groove 301, and the step unit 1 also includes a first sliding block 101, the first sliding block 101 is slidably set in the first sliding groove 301, the first sliding block 101 is connected to the upper end of the connecting seat 2 through the connecting member 4, and the pedal 3 is slidably set on the connecting seat 2 through the first sliding groove 301 and the first sliding block 101.

[0027] In some examples, it is suitable for construction sites where there is a need to fine-tune the position of the pedal 3, such as when it is necessary to avoid obstacles on the site. The pedal 3 cooperates with the first sliding block 101 on the connecting seat 2 through the first sliding groove 301 thereon to achieve the sliding of the pedal 3 on the connecting seat 2. The connecting member 4 connects the first sliding block 101 with the connecting seat 2 to ensure the stability and safety of the sliding. The position of the pedal 3 can be easily adjusted to adapt to different construction environments, thereby improving the versatility of the walkway ladder.

[0028] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, The step unit 1 also includes a connecting block 102, which is arranged in the connecting seat 2 for vertical movement. The first sliding block 101 is connected to the connecting block 102 through the connecting member 4. The pedal 3 and the first sliding block 101 move along the vertical direction following the connecting block 102. The pedal 3 has a fastening portion 302 at the bottom, and the clamping block 103 is slidably arranged on the connecting seat 2. Several clamping blocks 103 are respectively arranged on both sides of the fastening portion 302. The clamping block 103 slides close to or away from the fastening portion 302, and the clamping block 103 is used to clamp the fastening portion 302.

[0029] In some examples, the connecting block 102 moves vertically in the connecting seat 2, and drives the first sliding block 101 through the connecting member 4, so that the pedal 3 moves vertically. The fastening portion 302 at the bottom of the pedal 3 is clamped and fixed by the clamping blocks 103 on both sides. The pedal 3 is fixed, because one pedal 3 needs to be connected to multiple connecting seats 2, so the alignment of the connection holes is very troublesome. Therefore, after pressing down the pedal 3, the pedal 3 is clamped by the clamping block 103, and then the pedal 3 and the connecting seat 2 are installed and fixed more simply. Therefore, the connecting seat 2 may be offset, so the clamping block 103 clamps the fastening portion 302, which can limit the pedal 3 and facilitate installation.

[0030] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, The clamping block 103 has a guide hole 131, and the connecting block 102 has a guide portion 121, and the guide portion 121 passes through the guide hole 131. The connecting block 102 moves in the vertical direction to drive the clamping block 103 to slide along the guide portion 121, and the clamping block 103 slides close to or away from the fastening portion 302.

[0031] In some examples, the guide portion 121 of the connection block 102 passes through the guide hole 131 of the clamping block 103. When the connection block 102 moves vertically, the guide portion 121 drives the clamping block 103 to slide along the guide portion 121 to clamp or release the fastening portion 302. The accuracy and reliability of the clamping operation are ensured, and the safety of the walkway ladder is improved. It is particularly suitable for municipal engineering operations that require high clamping operations on the pedal 3. The matching accuracy of the guide hole 131 and the guide portion 121 can also be optimized to improve the smoothness of sliding, and the guide portion 121 can be surface treated to enhance wear resistance.

[0032] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, the guide portion 121 is in an eight-shaped shape, and the guide portion 121 passes through the guide holes 131 of the two clamping blocks 103 respectively.

[0033] In some examples, the guide portion 121 in an eight-shaped shape passes through the guide hole 131, and when the connecting block 102 moves, it can more effectively control the sliding distance and speed of the clamping block 103, thereby achieving rapid and stable clamping of the fastening portion 302. The efficiency and stability of clamping are improved to meet the needs of high strength and frequent use. Guide portions 121 of different shapes are used to achieve different clamping effects. The clamping block 103 clamps the fastening portion 302 and cooperates with the connecting seat 2 to limit the pedal 3 in the horizontal direction, and the guide portion 121 slides in the clamping block 103 to limit the pedal 3 in the vertical direction, so that the connecting block 102 cannot be separated from the connecting seat 2, so that the pedal 3 is separated from the connecting seat 2, which increases the stability of the pedal 3.

[0034] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, the ladder unit 1 also includes a baffle 104, the baffle 104 is connected to one end of the connecting seat 2, a plurality of the baffles 104 and a plurality of the pedals 3 are distributed in a stepped manner, the baffle 104 has a plurality of guide grooves 141, one end of the connecting seat 2 has a sliding portion 201, the sliding portion 201 is slidably arranged in the guide groove 141, and the cross-section of the sliding portion 201 is convex.

[0035] In some examples, the baffle 104 is connected to one end of the connection seat 2, and the sliding portion 201 at one end of the connection seat 2 slides in the guide groove 141 of the baffle 104, limiting the moving direction of the connection seat 2 and making the structure more stable. The overall stability and safety of the walkway ladder are enhanced, while reducing the space occupied. It is suitable for maintenance sites with narrow space and high requirements for the stability of the walkway ladder. The strength and protection area of ​​the baffle 104 can also be increased. A lubrication device is set in the guide groove 141 to reduce sliding resistance.

[0036] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, the ladder unit 1 also includes a second sliding block 107, the second sliding block 107 is vertically slidably set on the connecting seat 2, the connecting block 102 is swingably set on the second sliding block 107, the swing of the connecting block 102 is used to adjust the inclination angle of the pedal 3, the connecting block 102 is vertically slidably set on the connecting seat 2 through the second sliding block 107, one end of the elastic member 105 is connected to the connecting seat 2, and the other end of the elastic member 105 is connected to the second sliding block 107.

[0037] In some examples, the second sliding block 107 drives the connecting block 102 to move vertically, and the connecting block 102 can swing along the middle hinge point to adjust the angle of the pedal 3. The downward movement of the pedal 3 will cause the connecting block 102 to move downward, thereby causing the second sliding block 107 to move downward. The elastic member 105 connects the connecting seat 2 and the connecting block 102, and provides buffering and resetting force when the pedal 3 and the connecting block 102 move. When the connecting seat 2 and the pedal 3 are removed, the second sliding block 107 moves upward under the action of the elastic member 105, making disassembly more convenient. Reduce shock and vibration, and improve the comfort and safety of use. Suitable for industrial production environments that require buffering and shock absorption. Select elastic members 105 with different elastic coefficients to adapt to different working conditions, increase the protective cover of the elastic member 105, and extend its service life.

[0038] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, the ladder unit 1 also includes an anti-skid prism 106, there are a plurality of anti-skid prisms 106, and the plurality of anti-skid prisms 106 are evenly distributed on the surface of the pedal 3, and the anti-skid prisms 106 are in the shape of a broken line.

[0039] In some examples, the folded anti-skid prisms 106 evenly distributed on the surface of the pedal 3 increase the friction between the pedal 3 and the sole of the user's shoe, effectively preventing the user from slipping and ensuring personal safety, and are often used in wet or slip-prone places, such as outdoor municipal projects or construction sites with heavy rain. The shape and distribution density of the anti-skid prisms 106 can also be changed to meet different anti-skid requirements, and anti-skid materials with luminous function can be used to improve safety during nighttime use.

[0040] like Figure 1 to Figure 6 As shown, it shows an SMC composite material assembled walkway ladder in one embodiment of the present disclosure, the connecting seat 2 also has a connecting portion 202, and the connecting portion 202 is located at the bottom of the connecting seat 2, and the connecting seat 2 of the adjacent step unit 1 is connected to the pedal 3 of the adjacent step unit 1 through the connecting portion 202.

[0041] In some examples, the connection base 2 and the pedal 3 of the adjacent step unit 1 are connected through the connection portion 202 at the bottom of the connection base 2, which enhances the overall connection strength. The overall stability and durability of the walkway ladder are improved. It is applicable to heavy industrial scenes with high connection strength requirements or places that need to be used for a long time. The structure of the connection portion 202 can also be optimized to improve its bearing capacity and use high-strength connection materials.
